COMMODITY ANTITHEFT I1VVIPLEMENT
BACK GROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a commodity antitheft Implement for
preventing pilferage of commodities for rent such as diskswideotapes or game
software recorded with music images of CD cassettes or of various commodities
for
sales that are accumulated in cases, for preventing these commodities
including their
cases from being taken outside of the store without permission, and for
preventing theft
of various commodities for sales accumulated in such cases.
2. Description of the Prior Art
There exists a problem in, for instance, rental stores that pilferage and
theft of
commodities for rent cannot be prevented when displaying cases in which the
commodities for rent are being actually accumulated on shelves of the stores
since such
conventional cases are not provided with means for preventing; opening
thereof.
It is thus being employed a method in which empty cases are arranged and
displayed on the shelves of the rental store, and when a customer takes a
displayed
empty case of a commodity for rent bearing a title of his or he;r wish out of
the; shelf and
brings it to the counter, a salesperson standing by the counter will take the
corresponding commodity for rent as indicated on the empty case out of a
storage place,
and upon completion of specified lending procedures, the customer may rent the
commodity.
Employing such a method enables it to prevent theft of commodities for rent
since the customer will not directly touch the actual commodity for rent until
lending
procedures are completed.
However, it being troublesome for the salesperson to select commodities for
rent from the storage place or to maintain these commodities in a tidy manner,
such a
method is disadvantaged in that it is difficult to smoothly perform lending
procedures
and in that a wide storage place is required.
On the other hand~it would be possible to solve such a problem by displaying
cases accumulating therein commodities for rent on shelves of the rental
store, and
perfor~rrring lending procedures when a customer takes a commodity for rent of
his or
her wish out of the cases and brings it to the counter.
However, theft cannot be prevented since the customer may directly touch the
commodities for rent and take out of the store.
Some rental stores are now preventing theft of commodities for rent by
attaching antitheft tags with peculiar ID codes to arbitrary positions of the
commodities
for rent. A predetermined high frequency electromagnetic field is then
generated in a
gateway of the store, and when one tries to take a commodity for rent out
without
permission and passes through the gateway, such an unauthorized pass of the
commodity for rent may be detected upon resonance of resonance circuit of the
ID code
to generate a peculiar ID code and detection thereof upon demodulation thr-
oug;h the
high frequency electromagnetic field that the salesperson may observe.
Such a method is, however, disadvantaged in that commodities i:or rent of
which predetermined lending procedures have been completed will be detected
similar
to those taken out without permission unless such ID codes of the antitheft
tags are
shielded in some way when performing lending processes at the counter.
1
CA 02350889 2001-06-18
It thus resulted in a drawback of troublesome shielding procedures and
remarkable increase in costs owing to equipments accompanying the shielding.
Such problems are not limited to the above-described case with commodities
for rent but will also arise when employing antitheft tags for preventing
theft of various
commodities for sales such as clothing, accessories or daily nc;cessaries.
Theft of commodities that are accumulated in cases comprised, for instance, of
a box body and a cover body for opening and closing an aperture of the box
body
frequently occurs since it is easy to conduct pilferage of the commodities due
to the
openable arrangement.
Even if cases provided with opening preventing key members or sliders were
employed, it was still possible to open the cases since corresp~anding
portions that are in
latch with the key members or sliders could be broken or released by applying
forcible
force in a direction for opening the case.
Moreover, a case comprising a box body and cover body and prevc;nted from
being opened by means of a key member or slider may have the outer peripheral
wall
expanded outward when an external pressure is applied to the portion of the
inner and
outer peripheral walls at which the box body and cover body are to overlap
each other
inwardly or outwardly, the phenomenon being more noted as the pressure
increases.
When this phenomenon occurs, a finger or driver ca.n be easily forced into the
inside of the expanded portion of the outer peripheral wall, to prize open
the. case as it
stretches outward the open edge of the outer peripheral wall while forcibly
getting into
the expanded portion.
It is therefore an object of the present invention to provide a
commodity antitheft implement capable of blocking opening of the cases for
eliminating
pilferage of commodities for rent or of objects of which theft shall be
prevented and of
eliminating the necessity of providing shields by leaving tags for preventing
unauthorized takeout of commodities within the store, wherein cases may not be
opened
even upon application of forcible force in a direction for opening the cases.
These and other objects and features of the present invention will be
understood in details from the following descriptions with reference to the
accompanying drawings illustrating examples thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Figs.l to 3 are for illustrating a first embodiment of the commodity antitheft
implement.
Case A. according to the first embodiment is comprised of a shallow
rectangular box body 2 accumulating therein a commodity a. in the interior
thereof and
having an opening portion 1 for taking the commodity a in and out, and cover
body 4
provided at the box body 2 through hinges Sand arranged to open and close the
opening
portion 1.
The box body 2 is formed with peripheral walls 6 provided on four peripheral
edges of a square main wall 5 while the cover body 4 is forrned with
peripheral walls 6
provided on three peripheral edges of its square main wall '_>. By uniformly
forming a
lower edge of the main wall 5 to a lower peripheral wall of the box body2, the
box body
2 and the cover body 4 are uniformly molded by using synthetic resin.
As illustrated in Fig.3, the hinges 3 are subjected to half cut finishing at
corner
portions between a lower edge and the lower peripheral wall of the main wall 5
of the
box body 2 as well as at corner portions between the lower <;dge and a lower
peripheral
wall of the main wall 5 of the cover body 4, and the cover body 4 is thus
maf.e bendable
4
CA 02350889 2001-06-18
with respect to the box body 2 from a flat, fully opened condition to a
condition of
closing the opening portion 1.
When the opening portion 1 of the box body 2 is closed by the cover body 4,
the peripheral walls 6 of the cover body 4 will outwardly fit ~~rit.h the
peripheral walls 6
of the box body 2.
The peripheral walls 6, 6 of both, the box body 2 and the cover body 4 are
provided with through holes 7, 7 that coincide with key member 8 is inserted
into these
coincident through holes other when the box body 2 is closed by the cover body
4, and
holes 7, 7 from outside such that it nay freely be inserted and .drawn out.
By inserting the key member 8 into the through holes 7, 7, the closed.
condition
of the cover body 4 with respect to the box body 2 can be maintained, and by
drawing
the key member 8 out, the cover body 4 may assume an open position.
It should be noted that the structure of the above hinges 3 is not limited to
the
illustrated one, and it is alternatively possible to employ a structure in
which opening
and closing is affected by, for instance, separately provided hinges or pin
hinges of a
style in which holes and projecting shafts are fitted with each other.
The key member 8 is not limited to the illustrated plate-like body but may
also
comprise a square shaft or cylindrical shaft.
It will also be understood that while the illustrated through holes 7 ~~re
formed
as elongated holes that coincide with the peripheral shape of the plate-like
body of the
plate-like key member 8, these holes may be alternatively formed to meet the
peripheral
shape of the key member 8.
The shape of the through holes 7 may also be formed in a manner that it
engages with both side edge portions of the key member 8 as illustrated in
Fig.4.
The crucial point is that opening of the cover body 4 with respect to the box
body 2 shall be blocked by inserting the key member 8 into the coincident
through holes
7,7.
While the positions of the through holes 7, 7 are located at central portions
on
upper side of the peripheral walls 6, 6, opposing the illustrated hinges 3,
they may also
be formed on both end portions on upper sides or on both sides of the
peripheral walls
6, 6, depending on sizes or other reasons.
It is also possible to provide, in addition to the inner and outer overlapping
peripheral walls ~S, 6, formed with coincident through holes 7, 7, projecting
walls 9 to
extend from either or both main walls S in a parallel manner to oppose the
peripheral
walls 6 as illustrated in Fig.S, and by forming through holes 7 on these
projecting walls
9 that coincide with the through holes 7 of the peripheral walls 6, 6, the key
member 8
may be inserted into through holes 7 of both, the peripheral walls 6 and the
projecting
walls 9.
It should be noted that a distal end of the inserted key member may be hidden
in case L-shaped bent walls 10, 10 are provided outside of thf; peripheral
walls 6 formed
with the through holes 7 to be continuing from side edges of both main walks
5, 5 such
that the key member 8 may be inserted into the through holes 7 from between
the bent
walls 10, 10.
The provision of a guide means 11 within the case ,A for the key member 8 to
be inserted will enable smooth insertion of the key member 8 that is inserted
through the
through holes 7.
While the illustrated guide means 11 is comprised of rail strings 12 for
guiding
CA 02350889 2001-06-18
both side edges of the key member 8 formed on an inner surface of the main
wall 5 on
the box body 2 side and slip-off preventing strings 13 projecting out from the
rail strings
12 with respect to the main walls 5 while forming a clearance that is
somev~rhat larger
than a thickness of the key member 8 and further facing plate surfaces of side
edge
portions of the key member 8, it is alternatively possible to provide the
guide means 11
on the main wall 5 on the cover body 4 side. The shape of such means is
further not
limited to the stmcture comprised of the rail strings 12 and the slip-off
lareventing
strings 13 and may be formed to assume different shapes, e.g. as a cylindrical
lbody.
In such a case, stoppers 14 are provided at ends o1-' the rail strings 12
which
both sides of leading end edges of insertion of the key member 8 abut such
that distal
end edges of the inserted key member 8 and the surface of t:he outer
peripheral wall 6
are formed within a same plane.
The stoppers 14 may be formed as an arrangement other than those formed on
the rail strings 12, for instance, as protrusions formed on an inner surface
of the main
wall 5 or to employ an arrangement in which a brim 15 is formed at a distal
end of the
key member 8 as illustrated in Fig.7 wherein the brim 15 is fitted into a
concave portion
16 formed on the surface of the outer peripheral wall 6 with the surface of
the brim 15
being formed on the same plane as the surface of the peripheral wall 6 for the
purpose
of hiding.
A route for inserting the key member 8 will not contact the commodity a
accumulated in the case A even though the commodity a shall be unwrapped, and
it is
consequently possible to eliminate the occurrence of a case in which the
commodity a is
damaged through contact of the key member 8 with the unwrapped commodity a.
It is thus possible to eliminated damages of reG~rded surfaces or printed
surfaces though the commodities in question are unwrapped disks, to decrease
costs
since it is possible to leave commodities unwrapped, and to further to
eliminated
damages of accessories by the key member 8 in case accessories such as song
texts are
accumulated within the case A.
The commodity antitheft implement according to t:he second embodiment of
the present invention as illustrated in Figs.8 and 9 is arranged in that a key
member 8
that is inserted into case A is drawn out within the store.
Such a means for drawing out is arranged, as illustrated in Figs.8 and 9, in
that
a notch 20 is formed as an aperture for inserting a drawing tool 19 and in
that a pair of
latch portions 21 is formed on opposing surfaces or opposing edges of the
drawing tool
19 and the inserted key member 8.
The illustrated fitting member 21 is comprised with a protrusion 22 on one
member and of a hole 23 on the other member into which the protrusion 22 is
fitted to
and latched with.
Upon coincidence of the hole 23 and the protrusion 22 through the insertion of
the drawing tool 19, the protrusion 22 will fit into the hole 23 to assume: a
latched
condition, and by drawing the drawing tool 19 out after establishing the
latched
condition, the key member 8 will be simultaneously drawn out to thereby enable
opening of the case A.
The drawing tool 19 and the key member 8 that have been drawn out will be
left in the store for reuse. Thus, a case A that is not provided with a key
member 8 will
be case for sales or rent in case of a rental store.
It should be noted that while the hole 23 is formed at the drawing tool 19 and
6
CA 02350889 2001-06-18
the protrusion 22 at the key member 8 in the illustrated example, it is
possible to employ
an arrangement in reverse.
Smooth insertion of the drawing tool 19 is enabled in case a tapered surface
portion with its degree of projection increasing in approaching a leading
direction of
insertion is formed on an end surface in a projecting direction of the
protrusion 22 as
illustrated.
The commodity antitheft implement according to the third embodiment is
arranged in that an antitheft tag 24 is provided at the key members 8 of the
above-
described first and second embodiments through adhesion or embedding.
As exemplarily illustrated in Figs.8 and 9, the tal; 24 is comprised with a
known peculiar ID code, and when one tries to make a case A with the key
member 8
being inserted therein that is attached with the tag 24 pass through a gateway
of a store,
such an unauthorized pass of the case A may be detected upon resonance of a
resonance
circuit of the II> code and detection thereof upon demodulation through the
high
frequency electromagnetic field that the salesperson may observe to
consequently
preventtheft.
The key member 8 with the tag 24 is of course drawn out and left in the store,
and the case A accumulating therein an unwrapped commodity a is used as a case
for
sales or rent.
Prior to selling or lending, it is possible to block opening of the case A
through
the key member 8 and to effectively prevent shoplift or theft of an unwrapped
commodity a through the tag 24.
The commodity antitheft implement according to the. fourth embodiment of the
present invention is comprised, as illustrated in Figs.10 to 13" with a key
member 8 that
is inserted into case A similar to the first embodiment arid an engaging means
31
formed on the case A side to assume an engaged relationship upon insertion of
the key
member 8, and such engaged relationship may be released b:y inserting a
releasing tool
32 that is inserted into the case A.
The illustrated engaging means 31 includes an engaging claw 33 formed at a
side edge of the key member 8such that its degree of projection becomes
gradually
larger in approaching a distal end direction of the key member 8, and engaging
hole 34
into which the engaging claw 33 fits and engages at a portion midway of a rail
string 12
of the guide means 11 for blocking the key member 8 from being drawn out. When
the
engaging claw 33 contacts the rail string upon insertion of the key member 8,
the
engaging claw 33 will be pushed back, and upon completion of insertion of the
key
member 8, the engaging claw 33 and the engaging hole 34 will coincide such
that the
rail string 12 and the engaging claw 33 will not contact with each other.
Consequently, the engaging claw 33 that is released fron the force pushing the
same back will fit into the engaging hole 34 as illustrated in Fig.ll to
assume an
engaged condition for blocking the key member 8 fron being drawn out.
Instead of forming the engaging claw 33 and engaging gole 34 at the key
member 8 and the guide means 11, they may alternatively be formed on an inner
surface
of the main wall S of the box body 2 at a surface at which the key member 8
and the
case A oppose or' also on an inner surface of the main wall 5 of the cover
body 4.
In such a case, the engaging hole 34 fron among the; engaging claw 33 and the
engaging hole 34 comprising the engaging means 31 may be replaced by a
projecting
7
CA 02350889 2001-06-18
portion S 1 such as a projecting string or a protrusion projecting out from
the inner
surface of the main wall S of at least either one of the box body 2 or the
cover body 4 as
illustrated such that the engaging claw 33 contacts the projecting portion 51
;halfway of
insertion of the key member 8 to push the engaging claw 33 back through this
contact,
wherein the engaging claw 33 that is released of force pushing; the same back
will return
when the engaging claw 33 has completed passing the projecting portion 51
'while a tip
of the returned engaging claw 33 will hook at the projecting; portion 51 for
preventing
the key member 8 from being drawn out.
It should be noted that in case the projecting portion 51 is formed as a
projecting string as in the illustrated case, a piercing portion 52 for the
key member 8
may be formed as a notched through hole as illustrated in Fig. l 4 or Fig.18.
While the illustrated engaging claw 33 has been formed by cutting a slit 53
formed to substantially assume the shape of the letter U into the plate
surface of the key
member 8 and pushing the slit 53 out from inside, it is also possible to
fixedly attach a
separately arranged engaging claw to the key member or to uniformly forni the
same
with the key member 8 in a form of a molded plate made of synthetic resin.
The crucial point is that the key member 8 and the case A automatically
assume an engaged relationship upon completion of insertion of the key member
8 for
blocking the key member 8 from being drawn out.
In the case as illustrated in Figs.ll and 12, when the releasing tool 32 is
inserted through the through holes 7 serving as inserting apertures towards
the engaging
claw 33, a tapered jutting piece 35 projecting from a tip of the plate-like
releasing tool
32 will fit between an outer edge of a projecting piece 36, which projects
from the
engaging claw 33 in a direction directed to the distal end of the key member
8, and the
rail string 12, and when fitting is continued, the engaging claw 33 is pushed
and
released to escape from the engaging hole 34 whereupon the engaged
relationship is
released.
Accompanying the drawing out of the releasing tool 32, the key member 8 may
be drawn out together with the releasing tool 32 through frictional force
caused through
press-contact of the projecting piece 36 applied on the jutting piece 35
utilizing
resilience of the pushed and released engaging claw 33.
It should be noted that in case slip is caused at a portion where frictional
force
is generated, a combined latch portion 21 comprised of protrusion 22 and hole
23
similar to those of the second embodiment shall be formed at the key member 8
and the
releasing too132.
In case an engaging means 31 is provided on opposing surfaces as illustrated
in
Figs. l4 and 15, a notched portion 54 as illustrated in Figs. 16 and 17 that
is directed
inward fro a center of the projecting direction of the engaging; claw 33 may
be provided.
The engaged relationship between the engaging claw 33 and the projecting
portion 51
may then be released by fitting the jutting piece 35 of the releasing tool 32
that is
inserted through the notch 20 for insertion provided at edges of the through
holes 7 into
this notched portion 54 and pushing the engaging claw 33 back in the course of
fitting
operations.
The releasing tool 32 and the key member 8 are simultaneously drawn out
through latching affected by the fitting of the protrusion 22 and the hole 23
of the latch
portion 21 provided on opposing surfaces of the key member 8 and the releasing
tool
32.
8
CA 02350889 2001-06-18
Since the structure and the action of such latch portion 21 is identic;~l to
those
of the second embodiment, detailed explanations will be omitt:ed.
As described above, the key member 8 that has been drawn out simultaneously
with the releasing tool 32 is left in the store while the case A accumulating
therein
commodity a may be used as a case for rent or sales, and when being displayed,
opening
of the case A may be blocked by the key member 8 that is inserted into the
case A, and
the key member 8 is prevented from being drawn out by means of the engaging
means
31.
It is of course possible to attach an antitheft tag 24 to the key :member 8
including the engaging means 31, similar to the third embodiment, as
illustrated in
Fig.13.
In the drawing, 39 denotes a through window for pushing and releasing the
protrusion formed at the releasing tool 32.
In case the unwrapped commodity a accumulated within the case A. is a disk,
damages of its printed surface or recorded surface may be prevented by
arranging the
leading end of insertion of the key member 8 that is inserted iinto the case A
to stop at a
remote position with respect to a peripheral edge of thc; disk that is
temporally
supported by a central supporting member 40 such that the key member 8 and the
plate
surface of the disk do not contact each other as it is illustrated in Figs. l
and 2. Such an
arrangement omits the necessity of providing the above-described guide means
11.
The commodity antitheft implement according to the fifth embodiment of the
present invention is arranged in that assembled maintenance and release of the
assembled maintenance is enabled through a locking device C as illustrated in
Figs.l9
to 21 wherein an interposing member 42 is interposed into latch portion 41
such as a
hole or interposing portion formed on an object B of which theft shall be
prewented, the
interposing member 41 being folded into two to assemble both free ends
thereof.
In the illustrated case, the object B of which theft shall be prevented and
its
latch portion 41 are trousers and belt-inserting portion, while these may be
comprised of
button holes or holes formed on, for instance, mounts of blister-pack style of
display
cases; the crucial point is that the string-like or strap-like interposing
member 42 may
be interposed through.
In the illustrated case, the locking device C is arranged in that flat box-
shaped
bodies 43, 43 for inward and outward fit are provided on both ends of the
interposing
member 42 that is made of synthetic resin and provided to be foldable, and
through
holes 7 similar to those of the above-described first and second embodiiments
are
formed on overlapping or opposing peripheral walls of both box-shaped bodies
43, 43
that are fitted together. The key member 8 similar to tho:>e of the first,
second and
fourth embodiments is inserted through these coincident through holes 7 while
the key
member 8 is prevented form being drawn out through engaging means 31, and
releasing
tool 32 is used for affecting drawing the same out.
The interposing member 42 is of course attached with the antitheft tag 24,
similar to those the first, second and fourth embodiments, at a portion other
than the
interior of the box-shaped bodies 43 of the locking device C or the key member
8.
By attaching the interposing member 42, it is possible to prevent theft
through
unauthorized take-out of commodities, and after sales of the commodity in
question, the
interposing member 42 is simply removed from the object B of which theft shall
be
prevented and left in the store for reuse.
9
CA 02350889 2001-06-18
It should be noted that the locking device C is not limited to the above
arrangement, and locking and unlocking of the lock may also be affected by,
for
instance, inserting and operating a key provided at the store.
Since the guide means 11, through holes 7, key member 8, engaging means 31,
releasing tool 3f, and the tag 24 are similar to those of the first, second
and fourth
embodiments, detailed explanations will here be omitted.
The commodity antitheft implement according to the sixth embodiment of the
present invention is arranged, as illustrated in Figs.22 to 25, in that
fitting member 61
for blocking forced opening of the case A is provided at a distal end of the
ke;y member
8 of the first to fourth embodiments to be outwardly fitted to~ a side of the
case A upon
completion of insertion of the key member 8.
The fitting member 61 is formed in a shape of a lever having a groove-like
section that covers the peripheral walls 6 or both main walls 5, which
comprise the side
edge of the case .A, from outside. Though the same member is formed in a
linear shape
fitting the entire length of a single side edge in the illustrated example, it
is also possible
to employ arrangements in which the fitting member 61 is formed to assume a
shape of
the letter L with two sides pinching the corner of side edges at which the
through holes
7 are formed, or the letter U with three sides pinching the corner, and
further to employ
two fitting members 61 projecting from the key member 8 in mutually opposite
directions.
The crucial point is that opening shall be blocked through the fitting member
61, even if forcible force is applied in a direction for opening the box body
2 or the
cover body 4, by fitting the fitting member 61 from outside of the side edges)
of the
case A upon completion of insertion of the key member 8.
It is further possible to prevent damages of the fitting portion into which
the
key member 8 is pierced.
It should be noted that since arrangements and actions of the engaging member
31 of the inserted key member 8, the release of engaged relationship of the
engaging
means 31 through the releasing tool 32, uniform drawing of the releasing tool
32 and
the key member 8, and those of the tag 24 or the guide means 11 are similar to
those of
the first, third and fourth embodiments, detailed explanations will be
omitted.
In the drawing, 62 denotes and aperture for inserting the releasing tool 32
provided at the fitting member 61.
The commodity antitheft implement according to the seventh embodiment is
arranged, as illustrated in Figs.26 to 31, in that the case A is .comprised of
a t~ox body 2
having an opening portion 1 for taking a commodity a in and out, and a cower
body 4

CA 02350889 2001-06-18
It should be noted that the shapes of the engaging walls 71 and the slider 72
are
not limited to the illustrated ones, and any shape may be employed unless
opening of
the case A may be blocked through the engagement of the slider 72 and the;
engaging
walls 71 as an action of the inserted slider 72.
The case A being similar to that of the first embodinnent, detailed
explanations
will be omitted.
The slider 72 and the case A or the engaging walls 71 are provided with an
engaging means :31 that is pushed back upon insertion of thc; slider 72 and
that blocks
the slider 72 from being drawn out by automatically assuming an engaged
relationship
upon completion of insertion of the slider 72.
The engaging means 31 being comprised of engaging claws 33 and engaging
holes or engaging apertures 34 and thus similar to those of the fourth
embodiment,
explanations of arrangements and actions thereof will be omitted.
For releasing the engaged condition of the engaging means 31, a releasing tool
32 that is inserted towards the engaging claws 33 as illustrated in Figs.29
and 30 is
employed.
The releasing tool 32 may either be of a style similar to that of the third
embodiment or arranged, as illustrated in Figs.29 and 30, in that two engaging
claws 33
are disposed in the front and rear with respect to the inserting direction of
the slider 72,
wherein the engaged condition is released by pushing the engaging claw :33
located
remoter from the front by means of a bifurcated longer piece 73 and the
engaging claw
33 in the front by means of a shorter piece 74.
Insertion of the releasing tool 32 is affected from an aperture of the
engaging
wall 71 for inserting the slider 72 and is inserted into a clearance formed
between the
slider 72 and peripheral walls 6 of the case A, that is, between the engaging;
claws 33
and the engaging holes 34.
In view of uniform drawing of the releasing tool :32 and the slider 72, it is
preferable to provide, in addition to using frictional force ~of overlapping
surfaces, a
latch portion 21 which is a combination of protrusion 22 and hole 23, similar
to that of
the second embodiment.
Latching means 75 for blocking opening of the case A through forcible force
applied on the box body 2 and the cover body 4 in mutually opposite directions
are
formed on the case A and the slider 72 or the engaging walls 71 and the slider
72, the
means assuming a latched condition upon completion of insertion of the slider
72.
The illustrated latching means 75 is comprised of a projecting shaft 76 formed
at a leading end in an inserting direction of the slider 72, a through hole 78
on one side
and through hole 79 on another side formed on overlapping ~,valls 77 that are
formed to
continue from the main walls S of the box body 2 and thc; cover body 4 to
overlap
inwardly and outwardly. It is alternatively possible to employ a method in
which the
projecting shaft 76 is fitted through the through hole 78 into the hole. 79
upon
completion of insertion of the slider 72, or a method in which the projecting
shaft 76 is
fitted through the through hole 78 into the hole 79 upon connpletion of
insertion of the
slider 72, or a method in which plans- L-shaped carrying pierces 80 are formed
on both
sides of the distal end of the slider 72 with the carrying pieces 80 outwardly
contacting
both engaging walls 71, and it is further possible to achieve the same effects
through a
fitting means 75 provided on at least one end of the slider 72.
It is preferable that the tag 24 be attached to the slider 72.

In the commodity antitheft implement according to the eighth embodiment of
the present invention, case Ar is comprised, as illustrated in Figs.32 to 36,
a box body
102 including an opening portion 101 for taking a commodity a in and out, and
a cover
body 104 provided at the box body 102 through hinges 103 and arranged to open
and
close the opening portion 101, wherein inwardly and outwwdly overlapping
peripheral
walls 106, 106 are provided at peripheral edges of respective main walls 105
of the box
body 102 and the cover body 104.
In case of the illustrated hinges 103, the main wall lt)5 of the cover body
104 is
provided at a peripheral wall 106 on a lower side of the box body 102 through
the half
cut finished hinges 103.
Through holes 107, 107 that coincide with each other are formed at specified
positions of both peripheral walls 106, 106 of the box body 102 and the cover
body 104,
and a key member 108 is inserted into these coincident through holes 107, 107
to be
freely inserted and drawn out, wherein opening of the cover body 104, and a
key
member 108 is inserted into these coincident through holes 107, 107 to be
freely
inserted and drawn out, wherein opening of the cover body 104, and a key
member 108
is inserted in to these coincident through holes 107, 107 to be freely
inserted and drawn
out, wherein opening of the cover body 104 with respect to the box body 102 is
blocked
by the inserted key member 108.
In the illustrated case, the coincident through holes 107, 107 of both.
peripheral
walls 106, 106 ar-e formed as an elongated hole formed on the inner peripheral
wall 106
while a notch is :formed on the outer peripheral wall 106 to extend from an
open end of
the cover body 1104 towards the main wall 105, and a L-shaped latching piece
127 is
provided on an inner surface of the main wall 105 of the cover body 104 side
to serve as
an inserting guide for the key member 108 at the time of insertion and to
carry both side
edges ofthe key member 1080
Lt should be noted that smooth insertion and drawiing of the key member 108
might be perfornied in case of providing a guide means 109 for the key member
108 to
be inserted on an inner surface of the main walls 105 of the box body 102 and
the cover
body l04 as illustrated in Figs.32 and 34.
Continuous concave and convex portions 110 are firmed to fit in a mutually
meshing manner within specified regions at which a peripheral edge at a distal
end
opposite to the inserting direction of the key member 108 anf. open edges of
t:he through
holes 107 oppose.
As illustrated in Fig.36, even if one should try to forcibly press a head of a
tool
K such as a minus driver into a fitting portion between the through holes 107
and the
key member 108, the head of the took K will get snagged ;at the concave and
convex
edges of the concave and convex portion 110 to thereby black the pressing, and
it is
accordingly possible to eliminate forcible opening through prying of the
peripheral
walls 6 by pressing the tool K therein or to eliminate damages of the fitting
portion.
In case lengths of projections, depths of concave laortions and widths of the
concaves and convexes of the concave and convex portions 110 are set to be
smaller
than a length of a pointed edge with a flat tip of the tool K, picking
operations of the
tool K may be more effectively performed D
The shape of the concave and convex portions 110 is not limited to that of
Fig.36 but may be formed to assume a shape of saw teeth as illustrated in
Fig.44 or
waveform as illustrated in Fig.45 0
12
CA 02350889 2001-06-18
While the range for the concave and convex portions 110 formed on the
opposing surfaces extends as far as the entire periphery of the fitting
portion in the
illustrated case, it: is also possible to form these at longer side edges that
are parallel to
each other except for both ends of the fitting portion.
The opposing surfaces on which the concave and convex portions 110 are to be
formed may be the plate surface of the key
member 108 and the edges of the through holes 107, the key member
108 and the main wall 105 of the caseaAl,for example, as shown in
Fig.46,an upper surface of a stepped portion 161 that is indent from
below the through hole 107 formed on the inner surface of the: main
wall 105 and a lower surface that overlaps therewith when fitted into
a distal end stepped portion 161 of the key member 108 0
The key member 108 shall further be provided wil;h an antitheft tag 111 by
means of, for instance, an adhering means such as adhesive or an embedding
means
foamed at the time of molding.
Since the tag 111 includes a peculiar ID code in a manner known per se, when
one tries to make; the case A1 with the key member 108 being inserted therein
that is
attached with the tag l l lpass through a gateway of a store, passing of the
case A1 may
be detected upon resonance of a resonance circuit of the >D code provided at
the
gateway to generate a peculiar ID code and detection thereof upon demodulation
through the high frequency electromagnetic field to consequently prevent
thefit.
Collection of the key member 108 in the store and a means for engaging the
inserted key member 108 with the case A1 will now be explained.
As illustrated in Fig.33, a flange 112 that fits into through holes 107 upon
completion of insertion of the key member 108 is provided at a distal end of
the key
member 108, and the above-described concave and convex portions 110 are
provided on
both, the flange 112 and the through holes 102.
While the flange 112 is made to project from both plate surfaces and side
edges
of the plate surfaces of the key member 108 in the illustrated case, it is
also possible to
make the flange 112 project from only one of the plate surfaces of the key
member 108.
In this case, concave and convex portions 110 shall be provided on a plate
surface of the key member 108 other than that on which the flange 112 is
forrr~ed.
Since the width of the flange 112 is large, the width of a clearance formed
between the main wall 105 of the through hole 107 formed on the outer
peril>heral wall
106 and the opening of the cover body 104 is defined to be a width into which
the
flange 112 is fitted in case the through hole 107 is formed a:> an elongated
hole, and in
case the through hole 107 is formed as an elongated hole, and in case the
through hole
107 is formed as a notch as in the above-described case, the flange 112 shall
be inserted
into the notch.
An engaging means Br is formed on a surface at which the case A, and the key
member 108 oppose, wherein the means is pushed back accompanying insertion of
the
key member 108 and automatically assumes an engaged condition upon completion
of
insertion.
The engaging means B, is arranged, as illustrated in Figs.33, 34 and 37, in
that
slits 121, which are substantially formed in the shape of the letter U with
both ends
facing downward, are cut into the key member 108, and inner sides of the slits
121 are
made to project towards the main wall 105 of the cover body 104 to comprise
engaging
13
CA 02350889 2001-06-18
/lh
claws 122 provided to exhibit resilience utilizing characteristics of
synthetic resin of
which the key member 108 is made. An inner surface of the iinner peripheral
wall 106 is
made to function as engaging portions 123 that start pushing the engaging
claws 122
back through the edges of the through holes 107 immediately after insertion of
the key
member 108 has been completed, wherein the ends of the .engaging claws 122 in
the
projecting direction thereof, which have been released :&~om pushing force
upon
completion of insertion of the key member 108, engage with the engaging
portions 123.
It is alternatively possible to employ arrangements for the engaging means E~1
in which
separately arranged engaging claws are attached to the lkey member 1C18
through
adhesive or the like, or in which the engaging portions 123 are provided as a
projecting
portion formed at the main wall 105 of the box body 102.
The number of engaging claws 122 is not limited to two formed on the right
and left as in the illustrated case but may be freely determined, and thE;
engaging
portions 123 may as well be formed on the cover body 104.
In using the above case A1, the opening portion 1 t) 1 of the box body is
first
closed by the cover body 104 whereupon the key member 108 is inserted into the
coincident through holes 107, 107.
The engaging claws 122 are pushed back by the edges of the through holes
107, 107 accompanying the insertion, and upon completion of insertion at which
the
through holes 107 of the outer peripheral wall 106 are fitted, the engaging
claws 122
that are released from contact with the edges of the through holes 107 will
restore upon
release of force pushing these back to hook at the engaging portions 123 such
that the
engaging portions 123 and the engaging claws 122 are in engaged conditions as
illustrated in Fig.34.
Drawing out of the key member 108 by anyone other than the salesl>erson may
be blocked through this engaged condition and theft of comnnodity a within the
case A,
may thus be prevented.
Actions for drawing the key member 108 out by usiing releasing tool Cr at the
store will now be explained.
As illustrated in Fig.37, 38 and 39, the releasing tool C1 is located just
above
the engaging claws 122 of the flange 112, and by providing elongated holE;s
131 that
coincide with the through holes 107, jutting pieces 134 that project from a~
plate 133
with a grip 132 are pierced into these elongated holes 131.
When passing from central portions of ends in the projecting directions of the
engaging claws 132, the pierced jutting pieces 134 function to push the
engaging claws
122 back upon contact between bottom edges of the notchca 135 and tapered
surface
portions 136 provide on one side edge of the ends of the projecting pieces 134
in a
projecting direction thereof.
In this manner, the engaged condition between the engaging claws 122 and the
engaging portions 123 as illustrated in Fig.34 will be released when thf;
engaging
portions 123 come off the engaging claws 122 as illustrated in Fig.38, the key
member
108 may be drawn out when pulling the releasing tool C1 in a direction as
indicated by
the arrow in Fig.:39.
It should be noted that upon release of the engaged condition of the engaging
claws 122, resilience acting on the engaging claws 122 that have been pushed
back will
function to press the engaging claws 122 against the jutting pieces 134 so
that the key
member 108may be drawn out together with the releasing tool C1 through
frictional
14
CA 02350889 2001-06-18
/lh
force caused through pressing.
In order to ensure drawing actions, as shown in Fig.39, a through window 137
that coincides with the through holes 107 shall be formed next to the
elongated holes
131 of the flange 112 such that a projecting piece 138 projecting from the
plate 133 will
pierce through the through window 137 and the through hole:. 107.
The projecting piece 138 is formed with a slit 139 that is substantially
formed
in the shape of the letter U with both ends facing downward, .and an inner
side of the slit
139 is made to project towards the key member 108 to comprise a latching claw
140
that functions similar4 to the engaging claws 122.
The key member 108 is then formed with a latch portion 141 foamed as a
concave or through hole into which a tip of the latching piece 140 in the
projecting
direction thereof fits for latching upon completion of piercing of the
projeWing piece
138.
It is of course possible to form the latching piece 140 at the key member 108
while the latch portion 141 is formed on the projecting piece 138.
In such a case, the latching piece 140 abutting against the key member 108 in
the course of piercing the projecting piece 138 will be pushed back, and since
the
latching piece 140 and the latch portion 141 coincide when the engaged
condition of the
engaging claws 122 and the engaging portions 123 is released, the latching
piece 140,
which has been released from force pushing the same back, will fit into latch
portion
141 to assume a latched condition as illustrated in Fig.39.
It is therefore possible to reliably draw the key member 108 out when pulling
the releasing tool C 1 out.
The drawn out key member 197 is left in the store for reuse, and tile case Al
which key member 108 has been collected is used as a case for sales or rent.
Since no key member 108 with the tag 111 is present within the case; Ar, it
will
be possible to omit any shields for the Ar.
It is also possible to exhibit the same effects as those explained above with
reference to tool K by fitting pieces 142 projecting from the peripheral wall
106 into
inward end edges of the elongated holes 131 or through window 137 and by
providing
the above-described concave and convex portions 110 on surfaces at which these
pieces
142 and open edges of the elongated holes 131 or through window 137 oppose to
make
these concave and convex portions 110mesh with each other as illustrated in
Figs.32, 33
and 36.
While both, the projecting pieces 134 for releasing the engaged condition and
projecting pieces 138 formed with latching pieces 140 for drawing the key
member 108
out are provided on the releasing tool Cr, it is also possible to draw the key
member 108
out by means of a exclusively designed drawing tool comprising projecting
pieces with
latching pieces in case no engaging means Br are provided for the case Ar a.nd
the key
member 108.
In case the pieces 142 are fit into the through holes 131 or the through
window
137, clearances allowing passing of jutting pieces 134 or projecting pieces
138 shall be
provided.
In the commodity antitheft implement according to the ninth embodiment of
the present invention, the case Ar is comprised of the box body 102 as
illustrated in
Figs.40 to 42 or as illustrated in Figs.32 and 33 in relation to the eighth
embodiment,
and a cover body 104 provided at the box body 102 through lhinges 103 for
opening and
CA 02350889 2001-06-18
closing opening portion 101 of the box body 102, wherein continuous concave
and
convex portions 110 that fit with each other in a meshing condition are formed
at
specified regions on opposing surfaces of peripheral walks 106 of the case AI
that
inwardly and outwardly overlap with each other in an opening and abutting
manner or
on opposing surfaces of either one of the opening portion l01 of the outer
peripheral
wall 106 and the box body 102 or the cover body 104.
While the region for providing the concave and convex portions 110 is defined
to be other than the peripheral walls 106 at which the hinges 103 are formed
in the
eighth and ninth embodiments, they may be provided at arbitrary locations of
the
peripheral wall 6 upon suitable selection.
In the ninth embodiment, the concave and convex portions 110 are formed as
stepped portions overlapping inwardly and outwardly at the opening portion of
both
peripheral walls 106, 106 as illustrated in Figs.42 and 43 since surfaces of
both
peripheral walls 106, 106 of the box body 102 and the covE:r body 104 are
formed on
the same plane, .and such stepped portion may be formed on opposing surfaces
of the
fitting and abutting portion.
It should be noted that the concave and convex poritions 110 are formed on an
opening edge surface of the outer peripheral wall 105 in the eighth
embodiment.
The above concave and concave portions 110 may also be formed in a shape of
saw teeth or wave form as explained with reference to the eighth embodiment.
Similar 'to the eighth embodiment, the concave and convex portions 110 that
are in mesh with each other will block opening of the c<~se A1 through prying
by
piercing a tool.
In the drawing, 1 S 1 denotes a latching means of elastic piece style and is a
combination of a concave portion and projecting portion.
Figs. 47 and 48 are for illustrating a tenth embodiment ~of the commodity
antitheft
implement. Case A according to the tenth embodiment comprises a box body 2
having
an opening portion 1 for taking the commodity in and out, and a cover body 4
provided
at the box body 2 through hinges 3 and arranged to open and close the opening
portion
1. Case A is provided with a holding-down means 601 at a specified position of
the
peripheral walls 6,6 at which the box body 2 and cover body 4 are to overlap
each other
inwardly or outwardly, the means 601 serving to prevent ouW and expansion of
the open
edge of the outer peripheral wall 6 when an external pressure is applied
inwardly to at
least one of the opposing surfaces of Case A (opposing main walls 5,5 of the;
box body
2 and cover body 4).
Since the box body 2, cover body 4 and hinge 3 are similar to those of the
first
embodiment, detailed explanations will here be omitted.
As shown in these figures, Case A is provided with through holes 7, 7 in the
opposing peripheral walls 6, 6 on the hinges 3, through which a key member 8
is
inserted to prevent theft of a commodity "a" Case A holds therein, as is the.
case with
16
CA 02350889 2001-06-18
the first embodiment.
Since the through holes 7,7, key member 8, engaging means B which prevents
the inserted key member 8 from being drawn out by any one except the
salesperson, and
drawing out the inserted key member 8 by the salesperson are similar to those
of the
first embodiment, detailed explanations will here be omitted.
It is needless to say that the means for blocking opening of Case A of the
l0a' embodiment of the present invention to prevent theft of the commodity "a"
is not
limited to the key member 8, and other means can be employE;d.
The holding-down means 601 is to prevent outward expansion of the open
edge of the outer peripheral wall 6 by an external pressure. A,s shown in
Fig.49, Case A
is provided with a protn.ision 602 projecting towards the: open edge of the
outer
peripheral wall 6 to continue from the peripheral edge (main wall S) of the
shown cover
body 4 having the inner peripheral wall 6, and also with a tapered surface 603
overlapping the open edge of the outer peripheral wall 6 and the surface
opposing to the
protrusion 602, to hold down the tapered surface 603 inside of the outer
peripheral wall
6 by the outer tapered surface 63 of the protrusion 602 projecting from t:he
tapered
surface 603. The tapered surface may be replaced by a liner, wherein the
projecting
strings of the opposing surfaces are fit in each other to overlap both
inwardly and
outwardly.
The object can be achieved more efficiently by providing a projecting string
604 in a line with the inside of the outer peripheral wall 6 in such a way to
fit the inner
peripheral wall 6 between the outer peripheral wall 6 and projecting string
64.
The above structure can control external expansion of the outer peripheral
wall 6 of the peripheral walls 6, 6 overlapping each other by the holding-down
means
61, even when an external pressure is applied to Case A to bend it inwardly
(or towards
the opposite side).
The holding-down means 601 shown is provided only in two sides of the
peripheral walls 6,6 running in parallel to each other and having no hinge 3
~or through
holes 7,7 for the key member 8. However, it may be provided in another side
having
the through holes 7,7.
Figs. S l and 52 are for illustrating an eleventh embodiment of the
commodity antitheft implement. Case A according to the eleventh ernbodiment
17
CA 02350889 2001-06-18
comprises a box body 2 having an opening portion 1 and a cover body 4 provided
at the
box body 2 through hinges 3 and arranged to open and close the opening,
portion 1.
Case A is provided with a notched portion 71 at a specified position of at
least one of
the open edges of the peripheral walls 6,6 at which the box body 2 and cover
body 4 are
to overlap each other inwardly or outwardly, the notched portion 71 giving a
pain to the
finger coming into contact therewith.
The notched portion 71 shown has an uneven surdace like saw teeth, giving a
pain to the finger applying a forcible force at the open edge of the
peripheral wall 6 to
the periphery 9fi in a direction for opening Case A, to discourage application
of a
forcible force. The uneven surface is not limited to saw-teeth-like one, but
in any form
so long as it bites into the finger coming into contact therewith.
The notched portion 71 shown is provided at: the open edges of both
peripheral walls 6,6, but may be provided at the open edge of one of the
peripheral walls
6,6, i.e., outer peripheral wall 6 or inner peripheral wall 6. Moreover, it
may be
provided together with the holding-down means 61 of the eighth embodiment.
Since the box body 2, hinge 3 and cover body 4 a.s Case A's components are
similar to those of the first embodiment, detailed explanations will here be
omitted.
Case A is provided with through holes 7, 7 in thc; opposing peripheral walls
6, 6 on the hinges 8 , through which a key member 8 is inserted to prevent
theft of a
commodity "a" Case A holds therein, as is the case with the first embodiment.
Since the through holes 7,7, key member 8, engaging means B which
prevents the inserted key member 8 from being drawn out by any one except the
salesperson, and drawing out the inserted key member 8 by the salesperson are
similar
to those of the first embodiment, detailed explanations will here be omitted.
It is needless to say that the means for blocking opening of Case A of the
11~' embodiment of the present invention to prevent theft of the commodity "a"
is not
limited to the key member 8, and other means can be employed.
The notched portion 71 shown is provided only in t:wo sides of the peripheral
walls 6,6 running in parallel to each other and having no hinge 3 or through
holes 7,7
for the key member 8. However, it may be provided in another side having the
through
holes 7,7.
The above arrangements of the commodity antitheft implement according to
the present invention enables it to prevent pilferage of commodities within
the case or
18
CA 02350889 2001-06-18
taking cases accumulating therein commodities or objects of which theft shall
be
prevented out of the store without permission with the effect of eliminating
theft.
Since key members with tags are left in the tore upon sales or rf;nt, it is of
advantage that troublesome shielding may be omitted and the key member may
also be
reused in the store.
It is further possible to ensure accurate insertion along a specified line
