A storage case and a holder thereof
TECHNICAL FIELD
This invention relates to a storage case for use of
storing any thin product such as CD-~OMs (compact disk read
only memory), CDs (compact disk), printed materials, cards
and papers.
BACKGROUND ART
Recently, in accordance with the wide spread of personal
computer, many CD-ROMs have been used and CDs for use of
music also have been spread. These products are sold at shops
or through direct mail, or inserted in pages of any
information magazine as inserts. In such cases, usually the
CD-ROMs and CDs are stored in a storage case. Such cases are
formed in many variety of kinds, and a common shape thereof
is shown in Fig. 27.
It comprises a body 81 for storing a storage material A
~hereinafter referring to "the material A") such as a CD-ROM
or CD and a cover 82 connected to the body 81 in such a
manner it freely opens and closes for the body 81. The body
81 is formed with an engagement face 83 in concave-convex in
accordance with the shape of the material A.
Further, as another example, as shown in Fig. 28, there is
one storage case in which it comprises usually a paper-made
and tWo-ply storage face B4 and a paper-made cover face 85,
both faces 84 and 85 are divided at a central folding line 86
and the upper face of two-ply face 84 is at the side
adjacent to the folding line 86 opened as an insertion
opening 87 from the under face of the two-ply face 84, and
the other three sides of the upper face are bonded to the
under face of the storage face 84 to form a bag, and is
folded at the folding line 86. In thus formed storage case,
such an insertion opening 87 is sometimes provided on the
upper side or on the side opposite to the folding line 86 and
the cover face 85 is sometimes formed as a doubled-face which
CA 02262390 1999-02-04
W O 98/54722 PCT/JP97/04697
covers the upper face and the rear face of the storage face
84 to form a three-folded case including the storage face 84.
Thus formed bag-like storage case having the insertion
opening 87 has been used for storage case for all thin
plate-like products not only such as CD. In such cases,
there are what are produced from vinyl, or plastic sheet and
the like.
Further, as a storage case for filing the material A as an
insert in books, as shown in Fig. 29, it comprises an inner
case 88 for protecting the material A and a plastic-made
outer-case 89 is provided with a perforation 90 for opening
the outer-case 89 and the opposite surface which is not
formed with a perforation 90 for opening is bonded to a
given portion of one page of such as book. When opening the
perforation 90 by breaking it, the upper portion of the outer-
case 89 is opened along the perforation 90 through the
opening formed by breaking the perforation 90, and the
material A is taken out (patent laid-open publication No. Hei
6-199387).
Here, the above mentioned storage case has had the
problems mentioned below.
In the case of the storage shown in Fig. 27, since the
body 81 and the cover 82 are produced under separated
processes and both of them are assembled, eventually it needs
plural processes and is expensive in producing cost.
Further, despite of the material A, since the storage case
itself has a given thickness, it occupies a storage space.
In the case of the storage case in Fig. 28, although it is
not so much thick, and becomes approximately similar to the
material A in thickness, in order to prepare a storage face
84 it needs a folding process at a given portion and a
bonding process, which takes a lot of processes and time and
shows a low productivity. In case where the storage case is
produced with vinyl etc. it needs to model it into a given
shape and bond them by heating, eventually it needs a lot of
CA 02262390 1999-02-04
W O 98154722 PCT/JP97/04697
producing processes. In addition, since two-ply sheets having
a rectangular shape are bonded at their three sides with one
side only opened as an opening 87 for insertion, the opening
87 can not be opened large, so that the material A inside the
storage case is difficult to be taken out.
Further, in the case where the case is to be filed in
books, as shown in Fig. 29, an adhesive is to be applied on
the outer case 89 and in addition a page of the book to be
attached by the storage case has to be bonded with it, which
has been troublesome to handle them and time-wasted.
Further, the above storage cases are stored individually
as storage case or carried, so that, when it becomes plural
numbers, they become troublesome in handling them.
Accordingly, one object of the present invention is to
improve a storage case from the viewpoint of function, cost
and a wide usability compared with the above storage case,
and while resolving the above problems, by reducing the
number of processes and, cost to provide a storage case which
can reduce the space. Further, when filing in the books,
what is easily filed therein is provided. Further, such
storage case can be used in place of a stand at a shop. In
addition, such storage case can store easily memos and the
like and be used in place of an opened envelope. Still
further, the presen invention can provide such holder as it
can store plural number of storage case.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the first embodiment of the present
invention is explained. First, the structure of a storage
case 1 is explained on the basis of Figs. 1 ~ 4. As shown in
Fig. 1, the storage case 1 is made of a plastic sheet having
a rectangular shape, and coping with the width of the
material A, both ends of the sheet are folded in such a
manner as they are overlapped at short sides (see Fig. 4) to
CA 02262390 1999-02-04
W O 98/54722 PCT/JP97/04697
form an engagement face 2, a holding face 3 and a cover face
4. Here, folding portions (folding lines) of the plastic
sheet are designated as 5a and 5b. The engagement face 2 is-
provided with a cut 6 having an approximately convex shape,
as shown in Figs. 1, in such a manner as the convex is
directed toward the free end 2a of the engagement face 2.
Further, since the plastic sheet is folded coping with
the material A, the length L of the holding face 3 along the
longitudinal direction of the plastic sheet is identical with
the dimension of the material A.
The engagement face 2 and the cover face 4 are folded
along the folding lines 5a and 5b overlapping on the holding
face 3 to form a storage portion for the material A. At that
time, the cover face 4 overlaps on the engagement face 2 to
form a storage portion for storing the material, further the
free end 4a of the cover face 4 is inserted under an
engagement piece 7 (see Fig. 2) to make the storage case 1
close.
Then, the length L' of the cover face 4 along the
longitudinal direction of the plastic sheet, while the cover
face 4 and the engagement face 2 being folded, is set forth
in such a manner as the cover face 4 is overlapped in contact
with the surface of the cut 6. Further, in the state where
the material A is stored, the length and locations of the
ends 6a, 6a are in advance regulated in such a manner as the
material A is in contact with the ends 6a, 6a.
The above length L, L' and the dimension of the
engagement face 2 are freely determined as well as the
dimension of the cut in accordance with the dimension of the
material A.
When the material A is stored in the storage case 1, as
shown in Fig. 3, the free end 4a of the cover face 4 is
removed from the engagement piece 7 and while the engagement
face 2 is folded on the holding face 3, the material A is
inserted under the engagement piece 7 until the circumference
CA 02262390 1999-02-04
W098/54722 PCT/~97/04697
of the material A abuts to the ends 6a, 6a. Then, a free end
2a of the engagement face 2 becomes to be located under the
material A.
Subsequently, as shown in Fig. 4, the free end 4a of the
cover face 4 is inserted between the engagement piece 7 and
the material A to close the storage case 1.
Since the material A which is stored in the storage case
1 is supported at three positions i.e. the folded portion
along the folding line 5b and two ends 6a, 6a of the cut 6,
although the upper and lower edges of the storage case 1
(vertical direction) are opened, the material A does not
come out from the storage case 1.
Further, since the length L of the holding face 3, the
length L' of the cover face 4, and the location of the ends
6a, 6a of the cut 6 in the longitudinal direction of the
storage case 1 (horizontal direction in Fig. 4) are
determined in accordance with the dimension of the material
A, and in such a m~nn~r as the material A gets in touch with
the folded portion (along the folding line Sb) and the ends
6a, 6a, it is supported by the engagement face 2, the holding
face 3 and the cover face 4.
- In addition, in the above explanation, the shape of the
material A is illustrated as a disk (for instance, a CD), the
invention is not limited to it but, as shown in Figs. 5 ~ 7,
the storage case 1 can store all kinds of sheet-like or
paper-like thin material having any shape such as rectangular
or triangular.
Then, the storage case 1 comprises the engagement face 2,
the holding face 3 and the cover face 4 which are formed by
folding a plastic sheet in order to storage the material A
securely in the storage case 1 in accordance with the si~e of
the material A, and further it is a matter of course that the
length of the cut 6 is adapted to be set in accordance with
the size of the material A in such a manner as the material A
abuts to the ends 6a, 6a of the cut.

W098/54722 PCT/~97/04697
Next, the second embodiment of the storage case 21 of the
present invention is explained based on Figs. 8 and 9. The
structure of the second embodiment is almost similar to the ~
above first embodiment and the different portions are shape
of the cut 26 and projections 28, 28 provided on the free end
24a of the cover face 4.
In more detail, as shown in Fig. 8, the cut 26 is formed
on the engagement face 2 in such a manner as it curves
against the free end 2a and on the free end 24a of the cover
face 4 and at the both ends thereof triangular projections
28, 28 are provided. In that case, the cut is formed, in the
state where the engagement face 2 and the cover face 4 are
folded toward the holding face 3, in such a manner as
crossing points of the circumference of the projections 28,
28 with the free end 24a abut against the ends 26a, 26a of
the cut 26.
Since the storage case 21, as mentioned above, is
provided with the convex cut 26 and the projections 28, 28, as
shown in Fig. 9, when, after accomodating the material A, the
free end 24a of the cover face 4 is inserted under an
engagement piece 27, a pushing-down force is applied on the
cover face 4 and the projections 28, 28 abut to the ends 26a,
26a, so that the free end 24a becomes difficult to be removed
from the engagement piece 27.
Then, the shape of the projection is not limited to
triangle, which shape may be formed in such a manner as it
abuts to the ends 26a, 26a of the cut 26 in the state where
the engagement face 2 and the cover face 4 are folded, for
instance, as shown in Fig. 10, those may be almost of
rectangular shape 28', 28'.
Subsequently, one use example of the first embodiment of
the present invention is explained based on Figs. 1 and 11.
As shown in Fig. 1, the cut 6 of the storage case 1 is formed
in approximately convex shape, in such a manner it is
directed (projected) toward the free end 2a of the engagement
..... .. ... ..
CA 02262390 1999-02-04
W O 98154722 PCT/JP97104697
face 2 and a free end 4a of the cover face 4 is formed
linear.
Now, in the case where the material A is a sheet of
paper, it is a matter of course that the material A may be
put under the engagement piece 7, then the free end 4a of
the cover face 4 may be inserted under the engagement piece
7, however, as shown in Fig. 11, the folded material A may
be hooked on the engagement piece 7. In this case, even
though the material A does not abut the ends 6a, 6a, it is
secured in the storage case 1.
Next, another use example is explained based on Fig. 12.
In this case, the storage cases 1, 21 of the first and second
embodiments can be used as a stand for such as a calendar and
a memorandum. When using it as such, the engagement face 2
and the cover face 4 are folded on the holding face 3 in such
a manner as the former is folded on the front side of the
holding face 3 and the latter is folded on the back side of
the holding face 3. Due to this folding method, on the free
end 4a of the cover face 4 and the holding line 5a, the
storage case 1 stands, thus, it can be used as a stand by
inserting the material A in the cut.
The sheet for use of the storage case 1, 21 of the first
and second embodiment prior to folding can be manufactured by
one pressing and shearing process, in a pattern, of a
polyethylene sheet by using a press machine. Further, such
sheet may be of paper owing to the nature of the material A,
which can be manufactured under the same process.
Subsequently, the constitution of the third embodiment of
the storage case 31 of the present invention is explained
based on Figs. 13 and 14. Since the storage case 31 is so
formed as it is held on a holder H, first, the constitution
of the holder H is explained. The holder H, as shown in Fig.
15, comprises an approximately rectangular cover and back
cover 101 and 102 having a little larger size than the
storage case 31 respectively, and a rear cover 103, in the
1 0
CA 02262390 1999-02-04
W O 98/54722 PCT/JP97tO4697
inside of which, at its top end and its lower end, there are
provided with holding member 104, 104 for holding the storage
case 31.
The holding member 104 is of a U-letter shape in the plan
view or the bottom view as shown in Fig. 16.
Since the constitution of the storage case 31 according to
the third embodiment of the present invention is formed in
order to be able to be held on the holding member 104 of the
holder H, the structure around the folding line 5b of the
storage case 1, 21 is different from others. This is
explained based on Figs. 13 and 14 by referring to the area
X, for instance, in one dotted line around the folding line
5b of the storage case 21 shown in Fig. 8.
On the upper and lower sides of the cover face 4 and the
holding face 3, remaining projections 32, 32 two recesses 33,
33 are provided in trapezoidal shape adjacent to that
projections 32, 32. Two recesses 33, 33 on one side are
formed in such a manner as, when the sheet is folded along
the folding line 5b, the outline of two trapezoidal recesses
are overlapped completely.
Other constitutions of the storage case 31 except that the
projections 32, 32 are formed adjacent to the folding line 5b
are identical with ones of the storage case 21 shown in Fig.
8.
Since the storage case 31 is formed with polyethylene
sheet, the projection 32 is likely to be bent, and it has an
appropriate flexibility and elasticity. When the storage case
31 is held on the holder H, as shown in Figs. 17 and 18, the
projection 32 may be bent to be hooked on the holding member
104 and in order to remove it may be taken out of the holding
member 104 by making use of its elasticity.
In such constitution as a plurality of storage cases 31
are kept on the holder H, many storage cases 31 become
portable at a time.
Subsequently, a storage case 41, which can accommodate a
CA 02262390 1999-02-04
W O 98154722 PCT/JP91/04697
comparatively thick material A and has such thickness as it
is adapted therefor, is explained as a 4th embodiment.
As shown in Fig. 20, a storage case 41 is made from a
rectangular polyethylene sheet having a folding line 5a, Sb,
5c and 5d, along which the sheet is folded in that order to
make a chamber having an engagement face 42, a bottom portion
45, a cover face 44 and a upper portion 46 in such a manner
as both short sides are overlapped, and reference numeral 43
shows an engagement face~
At the central portion of the free end 42a (Fig. 19) of
the engagement face 42, a handle 47 is provided. The handle
47 comprises a rectangular portion connected to the central
portion of the free end 42a of the engagement face 42 and a
semicircular portion larger than the rectangular portion in
size and connected thereto, at which a hook hole 48 is
pierced for hooking the storage case 41. Further, the
engagement face 42 is provided with a cut 49 for being
inserted with the material A. The cut 49 is formed with a
pair of cuts parallel to the longitudinal direction of the
plastic sheet spacing each other by a given distance and a
convex cut arched for the free end 42a provided in such a
manner as it connected to the ends of the parallel cuts,
which are located near the side of the folding line 5a. And,
there are two cut out portions 60 formed in a rectangular
shape on the upper and lower sides of the engagement face 42
at the places near the free end 42a rather than the cut 49.
On both free ends 44a of the cover face 44, as well as in
the storage case 21 explained in the second embodiment,
approximately triangular tongue-like pieces 61, 61 are
provided. And, at the proximal and inside ends of the tongue-
like pieces 61, 61, there are provided with approximately
circular engagement holes 62, 62.
And, the holding face 43 is provided with a rectangular
opening h at central portion of and along the folding line
5c, which can pass the width of the semicircular portion of
CA 02262390 1999-02-04
W098/54722 PCTl~97/04697
the handle 47, and in communication with and adjacent to the
opening h a rectangular opening i, which can pass the width
of the rectangular portion of the handle 47 is provided on ~
the upper portion 46, and both openings h and i form a handle
engagement portion 63.
As shown in Fig. 20, when the engagement face 42 of the
storage case 41 is folded on the holding face 43 side along
the folding lines 5a, 5b, the handle 47 faces onto the handle
engagement hole 63 provided on the holding face 43 and the
upper portion 46. Then, the handle 47 can pass through the
opening h consisting the handle engagement hole 63, while
preventing it from passing through the opening i.
Accordingly, the handle 47 is inserted through the
opening h, the cover face 44 is folded on the engagement face
42 along the folding lines 5c and 5d and, as shown in Fig.
21, the free end 44a is inserted in the cut 49 to close the
storage case 41. At that time, the engagement portion 62 is
abutted to the ends of the circular portion of the cut 49 and
the free end 44a is kept therein.
Although the handle 47 inserted in the handle engagement
hole 63 is projected from the upper face 46 (see Fig. 21),
since the width of the semicircular portion of the handle 47
is larger than the width of the opening i of the handle
engagement hole 63, the storage case 41 can be maintained in
a closed state.
In the case where the material A is stored in the storage
case 41, the material A may be inserted in the cut 49 keeping
the engagement face 42 to be folded as shown in Fig. 22.
Then, since the storage case 41 is made from a hard
polyethylene sheet, the material A is kept in the cut 49 due
to appropriate elasticity.
Subsequently, when the storage case 41 stored with the
material A is closed, as well as the above the cover face 44
- may be folded and the free end 44a may be inserted in the cut
49. Since the storage case 41 is provided with the bottom
CA 02262390 1999-02-04
W098/54722 PCT/~97/04697
face 45 and the upper face 46, even if the material A is
thick or it is one of the overlapped thin materials in plural
number, the storage case 41 can accommodate it.
In the case where the storage case 41 stores the material
A which comprises a plurality of thin materials A and these
are easy to be loosened, in order to store these in a steady
state, these may be bundled with strings such as a rubber
string through the cut out portions 60, 60.
Subsequently, as 5th embodiment, a storage case 71 which
stores such as CD-ROMs as an insert of a magazine etc and is
filed in the same detachably is explained based on Figs. 23 -
26.
The storage case 71 is made of an approximately
rectangular plastic sheet, which is folded in accordance
with the size of the material A. At that time, one of the
folded faces is protruded or extended further from an
overlapping face to form a cover face 4, accordingly an
an engagement face 2, a holding face 3 and a cover face 4 are
formed, and further the portion protruded from the cover
face 4 becomes a filing piece 72. Since the constitution of
the engagement face 2, the holding face 5 and the cover face
4 is identical with the one of the storage case 21 as the
second embodiment, the following is an explanation about the
filing piece 72 which is connected to the end 4a'
(corresponding to the free end 4a) of the cover face 4.
The filing piece 72 is formed as follows. That is, it is
formed from what is extended from the cover face 4 (actually
from an end 4a' corresponding to the free end 4a of Fig. l).
Along this end 4a' and on the filing piece 72 a rectangular
opening 72' having a spacing L" shorter than the spacing
between the ends of the cut 26. From this opening 72', at its
width, two perforations 73a, 73b are applied to the upper and
lower sides of the cover face 4 and from the opening 72' to
the points, where the ends of the cut 26 are located, said
perforations 73a, 73b are cut (73c, 73d in Fig. 24) along the
1 4
CA 02262390 1999-02-04

perforation 73a, 73b to make two pieces surrounded by such
cuts 73c, 73d pick-up pieces 74', 74' and the pieces
surrounded by the perforations 73a, 73b removable pieces 74,
74.
In Fig. 24, the storage case 71 is formed by folding the
engagement face 2 and the cover face 4 along the folding
lines 5a, 5b. The material A is inserted, as shown in Fig.
24, and the opening 72'and the cuts 73c, 73d of the cover
face 4 inserted by the engagement piece 27 in such a manner
as the removable pieces 74, 74 are overlapped on the
engagement face 2, so that, as shown in Fig. 25, the
picking-up pieces 74', 74' are positioned on the engagement
piece 27, and the filing piece 72 is located out of the area
where the holding face 3, the engagement face 2 and the cover
lS face 4 are overlapped. Thus, the storage 71 is closed and
the material can not be taken out. And this filing piece 72
is filed in a book such as a magazine (reference F in Fig. 25
shows a filing line). The storage case 71 thus filed in a
magazine, by pulling the pick-up pieces 74', 74' to remove
the removable pieces 74, 74, as shown in Fig. 26, the cover
face 4 is separated from the cover face 4.
INDUSTRIAL APPLICABILITY
The storage case according to claim 1 of the present
invention, since it is formed by folding a rectangular sheet
from both ends thereof in accordance with the size of the
material, and such sheet can be produced by modeling a
pattern together with the cut and the spots to be pressed for
folding lines, is easily produced. Further, since the storage
case itself is quite thin, and the material itself to be
stored is presumed to be thin, even after storing the
material it may occupy a little storing space. And that,
since it is carried out by a simple insertion of the free end
of the cover face into the cut to close or open the storage
case, it is quite easy to store the material and take out it.
In the storage case according to claim 2 of the present
CA 02262390 1999-02-04
W O 98/54722 PCT/JP97/04697
invention, since the convex shape of cut provided on the
engagement face is formed in such a manner as the convex
direction thereof is forwarded to the free end of the
engagement face, it is quite easy to carry out the engagement
operation of the material and the cover face into the cut.
Except that, the effects identical with the ones of claim 1
are expected.
In the storage case according to claim 3 of the present
invention, since the free end of the cover face is provided
with the tongue-like projections from the touching points of
the free end to the cut ends out of the cut in such a manner
as these projections are overlapped on the engagement face so
as to engage with the cut ends when being inserted in the cut,
the cover face becomes difficult to be removed from the
engagement with the cut. Except that, the effects identical
with the ones of claim 1 are expected.
In the storage case according to claim 4 of the present
invention, since it is formed by folding a rectangular sheet
from both ends thereof in the accordance with the size of the
material and being modeled in a pattern by pressing
simultaneously by being formed with the cut and the folding
lines, it is easy to produce it. Further, since it is
provided with a bottom portion and a upper portion, the
material having such and such thickness or a plurality of
thin materials can be accommodated.
In the storage case according to claim 5 of the present
invention, since it is formed by folding a rectangular sheet
from both ends thereof in accordance with the size and shape
of the material and making a cut and folding lines
simultaneously with pressing it for modeling, it becomes easy
to be produced, and since the filing piece is extended from
the free end of the cover face through the central opening,
which is inserted by the engagement piece, such filing piece
is easily filed in a book with a page thereof, which makes a
filing process of the material in the book easy. Further,
1 6
CA 02262390 1999-02-04
W O 98154722 PCT/JP97/04697
since the filing piece and the cover face are connected
through cutting pieces, when the cutting pieces are cut away,
the storage case can be removed from the book, and it can be
used as the storage case for an insert or as a general
storage case. And that, since the cut is formed in such a
manner as the cut ends thereof are engaged with the material,
it is supported at the cut ends and becomes difficult to be
removed.
In the storage case of claim 6 according to the present
invention, since the portion accommodating the material is
formed with the engagement face, the holding face and the
cover face, and that the storage case itself comprises three
quite thin faces of the engagement, holding and cover, the
total thickness becomes thin, which takes a little storing
space.
In the storage case of claim 7 according to the present
invention, since it is formed in such a manner as a plurality
of the storage cases can be stored in the holder, which
becomes possible to keep a plural number of storage cases and
very convenient to carry them together. Except that, the
effects identical with claim 1 are expected.
In the holder of claim 8 according to the present
invention, it is formed in such a manner as it can hang
a plurality of storage cases inside the cover like a book.
