DESCRIPTION
SLIDE ACTION TYPE HINGED-LID PACKAGE
Technical Field
The present invention relates to slide action type
hinged-lid packages, and more particularly, to a hinged-lid
package that requires a slide action to open a hinged lid.
Background Art
As packaging containers for containing articles,
various types have been developed taking account of the
properties of articles to be contained. For example, where
the articles to be contained are smoking articles such as
cigarettes or filter cigarettes, hinged-lid packages are
very often used as such packaging containers.
One form of hinged-lid package has been proposed, for
example, in Patent Document 1.
The conventional hinged-lid package includes a box-
shaped outer body having an open end at the top thereof.
The outer body contains an inner pack, which includes a
bundle of cigarettes and an inner wrapper wrapping the
bundle.
A box-shaped lid is connected to a rear edge of the
open end of the outer body by a hinge. The lid is
pivotable about the hinge to open and close the open end.
Since this type of conventional hinged-lid package has
been in use for many years, consumers are used to its
opening/closing mode. It cannot be said, however, that the
conventional hinged-lid package has such appeal as to
encourage consumers to buy the package.
Accordingly, a slide action type hinged-lid package
which makes use of a slide action to open and close the lid
with a view to drawing consumers' attention has been
CA 02724107 2013-01-17

proposed, for example, in Patent Document 2.

Summary of the Invention
Problems to be Solved by the Invention
In the case of the conventional slide action type
hinged-lid package, the consumer slides up the inner pack
part while pushing, with his/her thumb or finger, the front
surface of the inner pack part exposed through a push-out
aperture. Accordingly, the consumer's thumb or finger may
possibly slip on the inner pack part, making it difficult
to slide up the inner pack part. Also, if the number of
the smoking articles contained is small, the inner pack
part is deformed when pushed with the consumer's thumb or
finger, making it difficult for the consumer to slide up
the inner pack part. In such case, extra effort is
required to take out a smoking article.
The present invention was made to solve the above
problems, and an object thereof is to provide a slide
action type hinged-lid package which is simple in
structure, employs an opening/closing mode so novel as to
stimulate consumers' buying motivation, and yet permits an
article contained therein to be taken out with ease.
Means for Solving the Problems
To achieve the above object, a slide action type
hinged-lid package according to the present invention
= CA 02724107 2013-01-17
3
comprises: an outer body having a rectangular parallelepiped shape and having
an
open end at a top thereof; and
an inner case slidably accommodated in the outer body and having a hinged
lid at an upper end portion thereof for opening and closing the inner case,
wherein the outer body includes an outer front wall and an opening formed in
the center of the outer front wall and allowing an inner front wall of the
inner case to
be partly exposed therethrough,
the inner case includes a reinforcing member affixed to an inner surface of
the inner front wall, the reinforcing member increasing the rigidity of the
exposed
portion of the inner front wall to resist pressure applied through the opening
when
the inner case is slid relative to the outer body, and
the inner front wall has a corrugated surface as an entire outer surface
thereof, whereby the corrugated surface is exposed through the opening when
the
inner case is slid relative to the outer body.
A consumer presses, with his/her thumb or finger, that
portion of the front wall of the inner case which is
exposed through the opening of the outer body, and then
moves up the inner case by sliding the inner case upward
with his/her thumb or finger. As a result, the inner case
projects from the upper open end of the outer body. Since
the reinforcing member is arranged on the inside of the
front wall of the inner case, the inner case has increased
rigidity, thus lessening deformation of the inner case.
Consequently, even if the number of articles contained in
the package has become small, the inner case can be
satisfactorily slid up without a hitch.
The slide action type hinged-lid package of the
present invention may further comprise engagement means for
CA 02724107 2013-01-17
3a
engaging the outer body and the inner case with each other,
and when the inner case is slid up relative to the outer
body, the engagement means causes the hinged lid to open
and also regulates an amount of sliding of the inner case.
Thus, with the package of the present invention, as the
inner case is pushed upward, the hinged lid gradually
opens, and the inner case is stopped when protruded from
the outer body by a predetermined length.
Specifically, the engagement means includes: a strip
arranged on the hinged lid, the strip having an upper end
connected to a rear part of the hinged lid by an upper
hinge which is located at a level higher than a lid hinge
allowing the hinged lid to open and close, and a lower end
CA 02724107 2010-11-10
- 4 -
portion forming a turned-back piece which is folded toward
an inner surface of the outer body; and a contact piece
arranged inside the outer body, the contact piece extending
from the open end toward the turned-back piece and capable
of engaging with the turned-back piece.
As the inner case moves upward within the outer body,
the turned-back piece at the distal end of the strip
becomes engaged with the contact piece of the outer body.
Since the rear part of the hinged lid is pulled relatively
downward by the strip because of the engagement, the hinged
lid gradually opens. As the inner case is further moved
upward, the hinged lid reaches a fully open position, where
the inner case is stopped and further upward movement is
prevented. Thus, an article contained in the package can
be taken out with ease, and it is also possible to
effectively prevent the inner case from dropping out of the
outer body. The contact piece is interposed between the
outer body and the inner case and thus is always in contact
with the inner case. Accordingly, the contact piece serves
as resistance to the upward-and-downward or reciprocating
movement of the inner case, thus preventing the inner case
from projecting to an undesirable extent from the outer
body.
Preferably, the front wall of the inner case has a
rough region formed at least on a portion of a surface
thereof which is exposed through the opening.
Where the rough region is formed on that portion of
the inner case which is exposed through the opening of the
outer body, it is possible to prevent the consumer's thumb
or finger from slipping on the inner case.
Advantageous Effects of the Invention
In the slide action type hinged-lid package of the
present invention, when the inner case containing articles
CA 02724107 2010-11-10
- 5 -
is slid up to be protruded from the outer body, the hinged
lid opens in a manner interlocked with the sliding
movement. Thus, the hinged-lid package of the invention
provides a unique, distinctive opening/closing mode, as
compared with ordinary packages, and therefore has such a
-ng appeal to consumers as to stimulate the consumers'
motivation to buy the package.

Mode for Carrying out the Invention
FIG. 1 illustrates a package 2 according to one
CA 02724107 2010-11-10
- 6 -
embodiment of the invention.
The package 2 is a packaging container for containing
smoking articles as tobacco product, such as cigarettes or
filter cigarettes, and is generally in the form of a
rectangular parallelepiped.
As illustrated in FIG. 2, the package 2 comprises an
inner case 6 having .a lid 4, and an outer body 8 slidably
accommodating the inner case 6.
The inner case 6 includes a box body 12, as shown in
FIG. 3, which contains inner packs 10.
The box body 12 is in the form of a box with its upper
end portion obliquely cut and has a size large enough to
contain two inner packs 10 side by side. Each inner pack
10 includes ten smoking articles of 95 mm long wrapped in
an inner wrapper. The inner wrapper comprises a sheet of
paper and a film of aluminum formed on one surface of the
paper sheet by vapor deposition. The aluminum film of the
inner wrapper not only serves to protect the bundle of
smoking articles from moisture but also prevents
dissipation of aroma from the bundle of smoking articles,
namely, from the individual smoking articles. For the
inner wrapper, laminated paper may be used instead of the
aluminum-metalized paper. In this case, the laminated
paper has a shielding layer formed therein for preventing
the passage of moisture and aroma.
More specifically, the box body 12 includes a
rectangular front wall 14, a rear wall 16 smaller in height
than the front wall 14, a pair of side walls 18, and a
rectangular bottom wall connected to the respective lower
ends of the front, rear and side walls 14, 16 and 18, as
clearly shown in FIGS. 3 and 4. Each side wall 18 has an
upper edge 18a slanted so as to connect the upper end of
the front wall 14 to the upper end of the rear wall 16.
CA 02724107 2010-11-10
- 7 -
Consequently, the box body 12 has a slanted opening at its
upper end portion.
The front wall 14 has a generally rectangular cut 20
formed in the center of an upper portion thereof. The cut
20 serves to open the front of the box body 12 wide, thus
making it easy to take out a smoking article. Also, a
rectangular reinforcing plate serving as a reinforcing
member for reinforcing the front wall 14 is bonded to a
portion of the inner surface of the front wall 14 located
at a lower level than the cut 20.
The rear wall 16 has an upper end provided with a lid
hinge 24. The lid hinge 24 extends between the rear ends
of the upper edges 18a of the two side walls 18, 18 and
connects the rear wall 16 and the lid 4 to each other.
As shown in FIGS. 2 to 4, the lid 4 includes a rear
wall 26 connected to the lid hinge 24, a top wall 28, and a
pair of trapezoidal side walls 30. The lid 4 is swingable
about the lid hinge 24. When the lid 4 is closed, the
oblique lines of the side walls 30 of the lid 4, that is,
the slanted lower edges 30a of the side walls 30 meet the
aforementioned upper edges 18a of the respective side walls
18 of the box body 12.
The inner case 6 further includes a strip 34 provided
at the rear of the lid 4.
The strip 34 is a tongue-like member generally
rectangular in shape. More specifically, as clearly shown
in FIG. 4, the strip 34 has an upper edge connected to the
lid 4 by an upper hinge 32 which is located at the center
of a boundary between the rear and top walls 26 and 28 of
the lid 4. Also, the strip 34 has a turned-back piece 36
at its lower end portion. The turned-back piece 36 is
formed by folding the lower end portion of the strip 34
outward in the thickness direction of the box body 12 to be
CA 02724107 2010-11-10
- 8 -
directed upward so that the turned-back piece 36 may remain
bent. Thus, while the inner case 6 is contained in the
outer body 8, the turned-back piece 36 of the strip 34 is
kept pressed against the inner surface of the outer body 8.
The strip 34 can be formed by using part of the rear
wall 26 of the lid 4 and part of the rear wall 16 of the
box body 12. Thus, as is clear from FIG. 4, a U-shaped
incision 22 is formed so as to extend from the rear wall 26
of the lid 4 past the lid hinge 24 to the rear wall 16 of
the box body 12.
The outer surface of the inner case 6 is formed as a
corrugated surface 6a by die forming over its entire area.
Specifically, the corrugated surface 6a has a large number
of ridges extending in the width direction of the inner
case 6 and spaced at regular intervals in the vertical or
height direction of the inner case 6.
The outer body 8 is a box in the form of a rectangular
parallelepiped having an open end 38 at the top thereof, as
shown in FIG. 1. More specifically, as shown in FIG. 3,
the outer body 8 includes a rectangular front wall 40, a
rectangular rear wall 42 having the same dimensions as the
front wall 40, a pair of side walls 44, and a rectangular
bottom wall connected to the respective lower ends of the
front, rear and side walls 40, 42 and 44. The front wall
40 has a generally rectangular opening 46 formed in the
center thereof, and the inner case 6 accommodated in the
outer body 8 is exposed through the opening 46 (see FIGS. 1
and 2).
Also, a contact piece 48 is provided at a rear edge of
the open end 38. More specifically, as clearly shown in
FIG. 3, the contact piece 48 extends from the rear edge of
the open end 38 toward the interior of the outer body 8
along the rear wall 42 and is folded along the rear edge to
CA 02724107 2010-11-10
- 9 -
be directed inward in the thickness direction of the outer
body 8 so that the contact piece 48 may remain bent. Thus,
the contact piece 48 is pressed against the inner case 6
accommodated in the outer body 8. When the inner case 6 in
the outer body 8 is slid in a direction toward the open end
'R, therefore, the contact piece 48 becomes engaged with
the turned-back piece 36 of the strip 34 of the inner case
6. Further, as is clear from FIG. 3, the contact piece 48
has a generally rectangular cut 50 formed in the center of
a lower end thereof. The width of the cut 50 is slightly
larger than that of the turned-back piece 36 of the strip
34. Accordingly, the contact piece 48 can reliably engage
with the turned-back piece 36 of the inner case 6. In this
manner, the strip 34 and the contact piece 48 constitute
engagement means.
The package 2 can be made by using an inner case blank
52 for forming the inner case 6 and an outer body blank 54
for forming the outer body 8.
As illustrated in FIG. 5, the inner case blank 52 has
a front panel 56 that constitutes the front wall 14 of the
box body 12, and a reinforcing panel 58 as the reinforcing
plate is connected to a lower part, as viewed in the
figure, of the front panel 56. Side panels 60, 60 for
forming the side walls 18 of the box body 12 are connected
to the respective side edges of the front panel 56.
Further, a bottom panel 62, which constitutes the bottom
wall of the box body 12, is connected to that end of the
front panel 56 which is located opposite the reinforcing
panel 58. A rear panel 64 for forming part of the rear
wall 16 of the box body 12 is connected to that end of the
bottom panel 62 which is located opposite the front panel
56.
Inner side flaps 66, 66, which are to be associated
CA 02724107 2010-11-10
- 10 -
with the respective side panels 60, are connected to the
respective side edges of the rear panel 64. Also, a rear
panel 68 for forming part of the rear wall 26 of the lid 4
is connected to that end of the rear panel 64 which is
located opposite the bottom panel 62, with a lid hinge line
'0 for forming the lid hinge 24 located therebetween. A
top panel 72, which constitutes part of the top wall 28 of
the lid 4, is connected to that end of the rear panel 68
which is located opposite the rear panel 64. Side panels
74, 74 for forming the side walls 30 of the lid 4 are
connected to the respective side edges of the rear panel
68. Further, inner top flaps 76, 76, which are to be
superimposed on the top panel 72, are connected to those
ends of the respective side panels 74 which are located
opposite the corresponding inner side flaps 66.
The blank 52 has a U-shaped incision 78 (incision 22)
extending from the rear panel 64 of the box body 12 to the
rear panel 68 of the lid 4. The region surrounded by the
incision 78 is a strip region 63 for forming the
aforementioned strip 34. More specifically, the strip
region 63 includes a lid rear panel 68b located in a
position corresponding to the rear wall 26 of the lid 4.
The lid rear panel 68b has an upper end connected to the
top panel 72 with a hinge line 80 for forming the upper
hinge 32 located therebetween. A case rear panel 64b and a
turn-back panel 64c for forming the turned-back piece 36 of
the strip 34, which correspond in position to the rear wall
16 of the box body 12, are connected successively to that
end of the lid rear panel 68b which is located opposite the
top panel 72.
An inner top flap 82, which forms the remaining part
of the top wall 28 of the lid 4, and an inner back flap 84,
which forms the remaining part of the rear wall 26 of the
CA 02724107 2010-11-10
- 11 -
lid 4, are connected successively to that end of the top
panel 72 which is located opposite the rear panel 68.
Also, a rear panel 86 for forming the remaining part
of the rear wall 16 of the box body 12 is connected to that
end of the inner back flap 84 which is located opposite the
inner top flap 82, with a hinge line 88 corresponding to
the lid hinge 24 therebetween.
As illustrated in FIG. 6, the outer body blank 54 has
a front panel 90 that constitutes the front wall 40 of the
outer body 8. Side panels 92, 92 for forming the side
walls 44 of the outer body 8 are connected to the
respective side edges of the front panel 90.
A bottom panel 94, which constitutes the bottom wall
of the outer body 8, is connected to the upper end, as
viewed in the figure, of the front panel 90. A rear panel
96 for forming the rear wall 42 of the outer body 8 is
connected to that end of the bottom panel 94 which is
located opposite the front panel 90. Inner side flaps 98,
98, which are to be associated with the respective side
panels 92, are connected to the respective side edges of
the rear panel 96. A contact panel 100 for forming the
contact piece 48 of the outer body 8 is connected to that
end of the rear panel 96 which is located opposite the
bottom panel 94.
In this embodiment, the blanks 52 and 54 are made of
paper having a basis weight of 180 to 270 g/m2 and a
thickness of 0.2 to 0.5 mm. Specifically, the blanks 52
and 54 may be made of cardboard, Manila cardboard or the
like. The inner case blank 52 is subjected to die forming
to form a large number of ridges on one surface thereof
which is to constitute the outer surface of the inner case
6 such that the ridges extend in the width direction of the
inner case 6, that is, in a direction perpendicular to the
CA 02724107 2010-11-10
- 12 -
sliding direction of the inner case 6, and are spaced at
regular intervals in the sliding direction.
The blanks 52 and 54 are individually folded along
fold lines indicated by the dot-dash lines in FIGS. 5 and
6, to form the inner case 6 and the outer body 8,
nectively. By folding the blanks, the package 2 with
the lid 4 closed as shown in FIG. 1 is obtained.
More specifically, the blank 52 is folded first to
obtain the package 2. First, the reinforcing panel 58 is
folded and glued to the front panel 56. Then, the turn-
back panel 64c of the strip region 63 is folded down and
also the lid rear panel 68b is folded along the hinge line
80 toward the outer surface of the blank 52, that is,
toward the outside of the box body 12 to be formed, so that
these panels may remain bent on the same side.
Subsequently, the side panels 74, 74, the inner top flaps
76, 76 and the top panel 72 are successively folded, and
the inner top flaps 76 are glued to the inner surface of
the top panel 72. Further, the inner top flap 82, the
inner back flap 84 and the rear panel 86 are successively
folded over and glued to the respective inner surfaces of
the top and rear panels 72, 68 and 64. Then, two inner
packs 10 are placed on the rear panels 64 and 68 with the
rear panel 86 therebetween, and with the two inner packs 10
placed in this manner, the inner side flaps 66, the bottom
panel 62, the front panel 56 and the side panels 60 are
folded around the inner packs 10 and glued together. Thus,
the inner case 6 containing the inner packs 10 is obtained
as an intermediate product.
Subsequently, the blank 54 is folded to obtain the
outer body 8. First, the contact panel 100 is folded down
toward the inner surface of the blank 54, namely, toward
the interior of the outer body 8 to be formed. Then, the
CA 02724107 2010-11-10
- 13 -
above intermediate product is placed on the rear panel 96
such that the rear panel 68 of the intermediate product is
superimposed on the contact panel 100. With the
intermediate product placed in this manner, the blank 54 is
folded around the intermediate product and glued in the
inner known in the art, thereby forming the package 2 of
FIG. 1 in which the inner case 6 with the lid 4 is
contained in the outer body 8.
The hinged-lid package of slide action type having
smoking articles packaged therein is obtained in this
manner, and each package is then wrapped in, for example, a
transparent film.
A consumer who has purchased the package 2 first
removes the wrapping film. Then, the consumer presses,
with his/her thumb or finger, the front wall 14 of the
inner case 6 exposed through the opening 46 in the front
wall of the outer body 8, and slides up the inner case 6.
As the inner case 6 is pushed up in this manner, the inner
packs 10 contained in the inner case 6 project from the
outer body 8 with the lid 4 opened.
The movement of the package 2 will be now described in
more detail with reference to FIGS. 7 to 10. At first, the
inner case 6 is in its entirety accommodated in the outer
body 8 with the lid 4 closed, as shown in FIG. 7. As the
inner case 6 is moved upward within the outer body 8, the
turned-back piece 36 of the inner case 6 becomes engaged
with the contact piece 48 arranged inside the outer body 8
(FIG. 8). The inner case 6 is further moved upward within
the outer body 8, and since the contact piece 48 and the
turned-back piece 36 are engaged with each other, the lid 4
begins to open as the rear part of the lid 4 is pulled
relatively downward by the strip 34, so that the inner
packs 10 are exposed (FIG. 9). As the inner case 6 is
CA 02724107 2010-11-10
- 14 -
further moved upward within the outer body 8, the lid 4
reaches a fully open position, where the inner case 6 is
stopped and is prevented from being moved upward (FIG. 10).
Namely, the engagement of the contact piece 48 with the
turned-back piece 36 causes the lid 4 to open and also
---Tulates the amount of sliding of the inner case 6.
In this embodiment, the positional relationship
between the contact piece 48 and the turned-back piece 36
and the length of the strip 34 are set so that the sliding
of the inner case 6 may be stopped at a position where the
smoking articles can be easily taken out from the upper
open end of the outer body 8 and also the lid 4 is fully
opened.
After the inner packs 10 are thus exposed through the
upper open end of the outer body 8, the consumer opens
either inner pack 10 and takes out a smoking article. To
put the inner packs 10 back into the outer body 8, the
consumer presses, with his/her thumb or finger, the front
wall 14 of the inner case 6 exposed through the opening 46
in the outer body 8 and slides the inner case 6 down, so
that the inner case 6 is withdrawn into the outer body 8.
As the inner case 6 is withdrawn, the contact piece 48 and
the turned-back piece 36 become disengaged from each other
and the lid 4 gradually closes while being guided by the
open end 38 of the outer body 8. When the inner case 6
finally comes into contact with the bottom wall of the
outer body 8, the lid 4 is completely closed, thus closing
the package 2.
When taking out a smoking article again, the consumer
has only to press the front wall of the inner case 6 with
his/her thumb or finger through the opening 46 and slide
the inner case 6 upward in the same manner as stated above.
Thus, in the slide action type hinged-lid package 2 of
CA 02724107 2010-11-10
- 15 -
this embodiment, the lid 4 can be opened in a manner
interlocked with the projecting movement of the inner case
6 from the outer body 8. The hinged-lid package 2
therefore provides a novel opening/closing mode and can
strongly appeal to consumers. Also, the outer surface of
the inner case 6 is in its entirety corrugated, and the
corrugated surface serves to prevent the consumer's thumb
or finger from slipping on the inner case 6 when the inner
case 6 is slid up, thus making it easier for the consumer
to slide up the inner case 6. Further, since the
reinforcing plate is attached to the inside of the front
wall 14 of the box body 12, the box body 12 has increased
rigidity, thus effectively preventing deformation of the
box body 12. Accordingly, even if the number of the
smoking articles contained has become small, the inner case
6 can be satisfactorily slid up and down without a hitch.
Also, according to this embodiment, by closing the lid
4 of the package 2, it is possible to prevent lowering in
freshness of the smoking articles. Moreover, the package 2
can be conveniently used as a tobacco case in such a way
that once the package 2 is bought, the consumer continues
to use the package 2 by refilling the package 2 with new
inner packs 10.
The present invention is not limited to the foregoing
embodiment alone and may be modified in various ways.
For example, in the above embodiment, the outer
surface of the inner case 6 is corrugated in its entirety.
Alternatively, only a surface region of the inner case 6
corresponding at least to the opening 46 of the outer body
8 may be corrugated. Also, in the foregoing embodiment, a
large number of ridges are formed on the outer surface of
the inner case 6. Antislip means is, however, not limited
to such ridges alone, and round bumps or round dimples may
CA 02724107 2010-11-10
, .
,
- 16 -
alternatively be distributed over the entire surface or
part of the surface of the inner case 6, for example.
Also, in the above embodiment, a rectangular plate
corresponding in shape to the front wall 14 of the box body
12 is affixed as the reinforcing member to the inside of
the front wall 14. Alternatively, plate members so
combined as to have a U-shaped cross section may be
arranged as a reinforcing member 102 within the box body
12, as indicated by the dot-dot-dash lines in FIG. 11, or
plate members so combined as to have a T-shaped cross
section may be arranged as a reinforcing member 104 within
the box body 12, as indicated by the dot-dot-dash lines in
FIG. 12. Namely, a reinforcing member with any desired
shape may be used insofar as it is capable of increasing
the rigidity of the box body 12. In FIGS. 11 and 12, thin
lines indicating the corrugated surface 6a of the inner
case 6 are omitted for simplicity's sake.
Further, the package of the foregoing embodiment is of
the type in which two inner packs each including ten
smoking articles of 95 mm long are contained.
Alternatively, the package may contain a single inner pack
