Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a CD (compact di
sk), DVD (digital versatile disk) and other disk-shaped recording media, tape-shaped recording media and media such as semiconductor memory, as well as various cards, thin or granular confectionery, etc. TECHNICAL FIELD The present invention relates to a storage case used for storage, in which a stored state of stored items is maintained and the storage case is not easily dropped from the storage case despite its simple structure.

[0002]

2. Description of the Related Art Conventionally, storage cases, for example, CD cases are generally made of plastic, and plastics are widely used because they are lightweight, have high strength, and have good moldability.

By the way, such plastic CDs
The case includes a base-side case for mounting a CD, and a turning lid rotatably supported on the base-side case.

In such a conventional CD case,
Since the other case (rotating lid) is rotated with respect to one case (base side case), a hinge portion is required. Formed generally.

[0005] Although not a CD case, there is a storage case in the form of a bag with one side edge opened, and the storage case is configured to store stored articles through the opening. Since such a storage case has a very simple structure and can be constructed by simply folding paperboard or the like or bonding a part thereof,
It can be manufactured at low cost.

[0006]

However, the former CD
In the case, there is a problem that the hinge portion is relatively fragile, easily damaged, and if the hinge portion is broken, the CD case no longer functions as a case.

[0007] In the latter storage case, since there is nothing to cover the opening in particular, there is a problem that the stored matter easily comes out and may be damaged or broken.

There is a case in which a flap is formed on one side edge forming the opening in such a storage case. However, simply folding the flap to cover the opening causes the opening to face downward or shake the storage case. The risk of the stored item easily coming out of the opening was extremely high.

In particular, there is a case in which the storage case is an outer case, the inner case is slidably provided with respect to the outer case, and the storage case is supported by the inner case, for example, as a storage case for confectionery. In all of these, wrapping or the like must be performed while the inner case is housed in the outer case to prevent the inner case from jumping out of the outer case.

Further, it is conceivable that the above-mentioned flap is attached to the other side surface by a snap button or a bellows. However, in this case, there is a problem that a product which can be manufactured at a low cost becomes expensive. Was.

[0011] Further, in a storage case mainly made of plastic material, recycling is difficult because fossil fuels (coal and petroleum), which are limited resources, are used as raw materials, and a thermo-effective resin is used. There are also environmental issues.

It is another object of the present invention to maintain a stored state of stored items and prevent the stored items from dropping easily from a storage case despite its simple structure.

[0013]

Therefore, in order to solve the above-mentioned problems, the storage case of the present invention is formed by folding a sheet-like member or a plate-like member and forming an opening at one side edge. A storage case for storing and removing stored articles through an opening, wherein a flap that covers the opening by bending is extended on one of two side surfaces that constitute the opening and oppose each other. Is formed with an insertion slit into which the flap is inserted.

Therefore, according to the storage case of the present invention,
Despite the simple structure, it is possible to prevent the storage items stored in the storage case from falling.

Further, the storage case using paper has an advantage of being recyclable and useful for environmental protection.

[0016]

In each of the drawings, the direction U is indicated by an arrow.
The D direction, the L direction, the R direction, the F direction, and the B direction mean upward, downward, leftward, rightward, forward, and backward, respectively. Further, the direction shown in the present specification is:
Since the surface of the inner case 3 of the CD case 1 for holding the CD 2 is referred to as a “mounting surface”, the direction is defined based on this surface, and the CD case 1 will be described in the present specification. This is for convenience.

The outer case 4 is formed by folding a blank (hereinafter referred to as "outer case side blank") 7 formed by stamping out a paperboard having the shape shown in FIG.

Specifically, the outer case-side blank 7 mainly includes a top panel 8, a bottom panel 9, and three side panels 10 (a left side panel 101, a right side panel 10r, and a back side panel 10b). The top panel 8 and the bottom panel 9 have a substantially square shape with one side slightly larger than the diameter of the CD 2.
Ob is formed wider than the sum of the thicknesses of both the CD 2 and the booklet 6. The above “top panel 8”
And the “bottom panel 9” respectively correspond to “two side faces” described in claim 1. In addition, the above “side panel 1”
0 (the left side panel 10l, the right side panel 10r, and the back side panel 10b) "together correspond to the" bundling part ".

A substantially trapezoidal drop-preventing piece 11 is integrally formed on the front edge of the upper panel 8, and the left and right side panels 101 and 10r are attached to the bottom panel 9 by the margins 12, 12. Are integrally formed. Note that the “drop-off prevention piece 11” corresponds to the “bent piece” described in claim 10.

A U-shaped cut line 16 is provided at a position slightly to the right of the left and right central portions of the drop-preventing piece 11.
Is formed, and a portion surrounded by the cut line 16 is formed as a flap 17, and the flap 17 is connected to the upper panel 8 by a fold line 13g between the upper panel 8 and the falling-off preventing piece 11, so that the flap 17 Is formed separately from the falling-off prevention piece 11.

As described above, the flap 17 is attached to the fall prevention piece 1.
Since the cut line 16 is formed in the outer case 1, an extra projecting portion can be reduced as the outer case-side blank 7, which contributes to a reduction in material cost.

The left and right side edges of the flap 17 are cut into a flat triangular shape, and a base end portion 18 located on the fold line 13g side, a substantially circular insertion portion 19 on the front end side, and a base end portion And a constricted portion 20 between the insertion portion 19 and the insertion portion 19.
A folding line 13h is formed at a position substantially the same as the width of the side panel 10 from the folding line 13g.
A portion between the outer case 3h and the cover 3h is a cover 21 that covers the inner case insertion opening 5 of the outer case 4 described later.

An arc-shaped cut line 22 that opens forward is formed at a position of the insertion portion 19 of the flap 17 that is closer to the constricted portion 20, and a flat hooking piece 23 that extends rearward due to the formation of the cut line 22. Are formed. Note that the “front” and “rear” here mean that the two fold lines 13g and 13h of the flap 17 are both bent 90 ° and the covering portion 21 is formed.
In a state in which the inner case insertion opening 5 is covered by the cover.

A cut extending in the left-right direction at a position slightly closer to the right of the left and right center portions of the leading edge of the bottom panel 9 and corresponding to the flap 17 when the outer case-side blank 7 is assembled. (Hereinafter referred to as "insertion slit"
That. ) 24 is formed, and the insertion slit 24 is formed.
Is formed to be substantially the same as or slightly smaller than the lateral width of the insertion portion 19 of the flap 17. This means that after inserting the insertion portion 19 of the flap 17 into the insertion slit 24,
This is to prevent the flap 17 from easily coming off.
When inserting the insertion portion 19 of the flap 17 into the insertion slit 24, it is possible to easily insert it by bending the both ends of the flap 17 between fingers and pushing it in.

In the insertion slit 24, three slits (hereinafter, referred to as "orthogonal slits") 25, 25, 25 are formed rearward.

Thus, the outer case-side blank 7 thus formed is connected to the respective folding lines 13a, 13b, 13c, 13c.
By bending d, 13e, 13f and 13g,
It is assembled into a flat, thin box with one front side open.

That is, first, the falling-off preventing piece 11 is folded 180 ° along the folding line 13g so as to be along the inner surface of the upper panel 8.

Next, each of the fold lines 13a, 13b shown in FIG.
13c, 13d, 13e, 13f are bent almost 90 °,
The left and right sides of the bottom panel 9 and the above-mentioned margins 12 and 12 are adhered with an adhesive, whereby the outer case-side blank 7 is
Is assembled in an outer case 4 having a flat thin box with an open front (see FIG. 4). At this time, the flap 17 is positioned so as not to be folded and to protrude forward from the opening edge of the outer case 4.

It should be noted that the fall-off prevention piece 11 is folded according to the above-mentioned fold lines 13a, 13b, 13c, 13d, 13e, 1e.
According to 3f, each panel 8, 9, 10l, 10r, 1
Ob may be folded to assemble a flat thin box, and then folded into the thin box (see FIG. 5).

After the inner case 3 described later is housed in the outer case 4, the flap 17 has a folding line 13 g,
13h are bent approximately 90 °, and their insertion portions 19
Is inserted into the insertion slit 24.

The inner case 3 is formed by folding a blank formed by punching a paperboard having a shape shown in FIG. 6 (hereinafter referred to as “inner case side blank”).

Specifically, the inner case side blank 26 is
A substantially rectangular inner case bottom panel 27 serving as a bottom plate of the inner case 3, a CD mounting panel 28 on which CD 2 is mounted on one side with the inner case bottom panel 27 interposed therebetween, and a CD 2 on the other side. It consists of a holding panel 29 for preventing detachment from the inner case 3, and an inner case side panel 30 located between the inner case bottom panel 27 and the holding panel 29. These panels (the inner case bottom panel 27, CD The left and right width dimensions of the mounting panel 28, the holding panel 29, and the inner case side panel 30) are substantially the same as or slightly smaller than the left and right inner dimensions of the outer case 4.

Each of the panels 28, 29 and 30 of the inner case side blank 26 is formed by a fold line 31 as shown in FIG.
a, 31b, and 31c. FIG.
Is a view of the inner case-side blank 26 as viewed from the bottom side. Therefore, the folding lines 31a, 31b and 31c are mountain fold lines, which are indicated by dashed lines.

Between the inner case bottom panel 27 and the CD mounting panel 28, the above-mentioned fold line 31a is divided so as to hang on both panels and open in the inner case bottom panel 27 side. Is formed, and a portion surrounded by the cut line 32 is formed as a locking piece 33 (FIG. 6).
reference). Further, two folding lines 3 are provided at the base end side of the locking piece 33.
4a, 34b are formed, and respective fold lines 34a, 34
When b is bent by approximately 90 °, the locking piece 33 can be positioned above the CD mounting panel 28 (see FIG. 9), and when the inner case 3 is stored in the outer case 4. The locking piece 33 is engaged with the falling-off preventing piece 11 of the outer case 4 so as not to come off from the outer case 4. Note that the “drop-off prevention piece 11” and the “locking piece 3”
"3" corresponds to the "fall-out preventing means" described in claim 9.

Many parts of the CD mounting panel 28 opposite to the side connected to the inner case bottom panel 27 are CD2.
In addition, tongue-shaped wings 35 are formed on both left and right edges near the inner case bottom panel 27 side, respectively.
5, 35 are C through folding lines 36, 36, 36 ', 36'
It is connected to the D mounting panel 28. In FIG. 6, only the fold lines 36, 36, 36 ', 36' are valley fold lines. Also, the fold lines 36, 3 of the wing pieces 35, 35
6, 36 'and 36' are formed so as to be located slightly outside the outer peripheral edge of the CD2 when the CD2 is mounted on the CD mounting panel 28.

The interval h between the fold lines 36, 36, 36 ', 36' is formed to be substantially the same as or slightly larger than the thickness h 'of the CD2, and the fold lines 36, 36, 36', 36 'are formed.
Is folded, the CD 2 is located in the gap between the CD mounting panel 28 and the wing 35. A space h is also formed between the two fold lines 34a and 34b formed on the base end side of the locking piece 33.

The inner case blank 26 formed as described above is formed by folding the folding lines 31a, 31b and 31c, thereby forming a portion where the panels 27, 28 and 29 are overlapped and the booklet 6 is stored. And an inner case 3 configured to be divided into a portion for storing the CD2.

That is, first, the inner case bottom panel 27
The booklet 6 is placed thereon (see FIG. 7), and the CD mounting panel 28 is moved by approximately 180 degrees according to the folding lines 31a, 31a.
° Fold (see FIG. 8). At this time, the wing pieces 35, 35 are bent by approximately 90 ° with respect to the CD mounting panel 28 (see FIG. 8). It should be noted that a fold line 31a 'having an interval d substantially equal to the thickness d' of the booklet 6 is formed, and the fold line 31a 'is bent substantially at a right angle. This allows
The booklet 6 having the thickness d 'is sandwiched between the inner case bottom panel 27 and the CD mounting panel 28, and when the booklet 6 is stored, the CD mounting panel 28 and the holding panel 2
9 can be prevented, and pressure on CD2 that would be caused by these deformations can be prevented. Therefore, it also contributes to preventing the warpage (skew) of the CD2.

Next, the restraining panel 29 and the locking piece 33 are bent substantially 90 ° with respect to the inner case bottom panel 27 according to the folding lines 31b and 34a.
2 is mounted on the CD mounting panel 28 (see FIG. 9).

Finally, the holding panel 29, the locking piece 33, and the wing pieces 35, 35 are connected to these folding lines 31c, 34b, 3c.
Bending according to 6, 36, 36 ', 36'
The inner case 3 supporting the CD 2 and the booklet 6 is completed (see FIG. 10). Of course, CD2 and booklet 6
Instead of sandwiching the inner case side blank 26 in the middle of folding, after assembling the inner case 3, each of these panels 2
8, 29 and 30, open each panel 28, 29, 30
The CD 2 and the booklet 6 may be interposed therebetween.

The folding lines 34a and 34b of the locking piece 33
The gap between the fold lines 31b and 31c of the holding panel 29 is substantially the same as or slightly larger than the diameter of the CD2, so that the CD2 supported by the inner case 3 is prevented from moving in the front-rear direction, Since the fold lines 36, 36, 36 ', 36' of the left and right wing pieces 35, 35 are provided so as to be close to the outer peripheral edge of the CD 2, the movement of the CD 2 in the left-right direction is also suppressed. Thus, when the inner case 3 supporting the CD 2 is stored in the outer case 4 as described later, the CD 2 does not rattle in the outer case 4.

The folding lines 34a and 34b and 36 and 3
Since the interval of the width h is provided between 6 ', the CD2 is not pressed, and therefore, there is no possibility that the CD2 is twisted (skewed).

Next, the storage of the inner case 3 in the outer case 4 will be described.

The inner case 3 is stored in the outer case 4 by inserting the inner case 3 from the inner case insertion opening 5 of the outer case 4 into a folding line 31 between the CD mounting panel 28 and the inner case bottom panel 27.
a, 31a (see FIG. 11).

At this time, the locking piece 33 of the inner case 3 and the falling-off prevention piece 11 of the outer case 4 are respectively connected to the folding lines 31a, 3a.
Since the sliding pieces 1a and 13g are slid and inserted from the side, the inner case 3 is smoothly housed in the outer case 4 without the locking piece 33 and the falling-off prevention piece 11 being caught (FIG. 12).
reference).

Thus, the CD case 1 is completed by storing the inner case 3 in the outer case 4.

Further, when the inner case 3 is simply stored in the outer case 4, the inner case insertion opening 5 is in an open state, and there is a risk that the inner case 3 is easily detached from the outer case 4. .

Therefore, the flap 17 is moved to the folding line 13
g and 13h, and inserted into the insertion slit 24 formed in the bottom panel 9 (see FIG. 12).

At this time, since the orthogonal slits 25, 25, 25 orthogonal to the insertion slit 24 are formed, the insertion slit 24 can be easily opened, and the insertion portion 19 of the flap 17 can be inserted. The insertion into the insertion slit 24 can be easily performed (see FIGS. 13 and 15). Further, the length of the insertion slit 24 is substantially the same as or slightly smaller than the width of the insertion portion 19 of the flap 17, but the insertion portion 19 of the flap 17 is slightly curved to insert the insertion slit 24. It can be easily inserted if it is inserted into.

Although not shown, the insertion slit 2
If the slit width of 4 is made slightly larger, the insertion can be further facilitated.

As a result, the inner case insertion opening 5 of the outer case 4 is covered with the flap 17, so that the inner case 3 does not come off from the outer case 4.

Further, the flap 17 inserted into the insertion slit 24 is formed so that the left and right width of the insertion portion 19 is substantially the same as or slightly larger than the left and right length of the insertion slit 24, and the constricted portion 20 is formed. Once formed, the flap 17 once inserted does not easily come out of the insertion slit 24, and even if the CD case 1 is turned downward or the inner case insertion opening 5 is shaken, the CD case 1 is inserted inside. The case 3 does not easily come out of the outer case 4.

FIGS. 14 and 16 show a state where the hook 23 of the flap 17 is hooked on the insertion slit 24.

Since the hook piece 23 is formed on the flap 17, the hook piece 23 can be hooked by slightly raising the hook piece 23 from the surface of the flap 17, and the hook piece 23 can be hooked on the insertion slit 24. 1
The inner case insertion opening 5 can be relatively easily covered without inserting the insertion portion 19 of the connector 7 into the insertion slit 24.

In this embodiment, the hook 23 of the flap 17 is hooked on the insertion slit 24. However, the present invention is not limited to this, and the insertion slit 24 is formed as a separate slit. May be hooked to a separate slit.

Then, in order to pull out the inner case 3 from the inside of the outer case 4, the above-mentioned flap 17 is inserted into the insertion slit 24.
After removing the inner case 3 from the bottom opening 14 and the upper opening 15, the inner case 3 is gripped by the thumb and the index finger, and the inner case 3 is pulled out in the pull-out direction.

At this time, the inner case 3 is
In a state where 9 is exposed from the inner case insertion opening 5 (see FIG. 17), the locking piece 33 and the drop-off preventing piece 11 are locked, so that further pulling-out cannot be performed.
The inner case 3 is dropped from the outer case 4 and the CD 2 is dropped.
Breakage can be prevented (see FIG. 19).

Next, when taking out the CD 2 and the booklet 6 from the inner case 3 pulled out from the outer case 4 by a predetermined amount, the holding panel 29 of the inner case 3 is opened and at the same time the inner case bottom panel 27 is slightly bent downward. If the CD 2 and the booklet 6 are exposed so that they can be gripped, the CD 2 can be easily read.
And the booklet 6 can be taken out. (FIG. 19, FIG. 2
0).

Conversely, when inserting the CD 2 and the booklet 6 into the inner case 3, the holding panel 29 is opened with the inner case 3 pulled out from the outer case 4, and the inner case bottom panel 2 is opened.
7 is bent downward, so that the CD 2 is placed on the CD mounting panel 28 and the booklet 6 is placed on the inner case bottom panel 27.
And the CD mounting panel 28 can be inserted into the space (see FIGS. 19 and 20).

FIG. 21 shows a modified example of the flap 17, and the difference between the flap 17A according to the modified example and the flap 17 according to the above embodiment is the formation position thereof.

More specifically, as shown in FIG. 21, the flap 17A is formed in the shape of a tongue on the opening side edge of the bottom panel 9 of the outer case side blank 7A.

Although not shown, the flap 17A
However, when the outer case-side blank 7A is folded and the outer case 4 is assembled, the outer case 4 functions so as to cover the inner case insertion opening 5 and can effectively prevent the inner case 3 from jumping out. Can prevent the CD 2 and the booklet 6 from falling.

FIG. 22 shows another modification of the flap 17 and a modification of the insertion slit 24. The flap 17B according to the other modification differs from the flap 17 according to the above-described embodiment in that a notched portion 37 is formed at the formation position and the constricted portion 20. Also,
The insertion slit 24 </ b> B according to the modification has the formation angle.

Specifically, as shown in FIG. 22, the flap 17B is formed in the shape of a tongue on the opening side edge of the bottom panel 9 of the outer case side blank 7B, and the constricted portion 20B is formed.
Is formed with a notched portion 37. The notched portion 37 is for preventing the flap 17B from coming out of the insertion slit 24B when the flap 17B is inserted into the insertion slit 24B, and thereby the inner case 3 housed in the outer case 4 protrudes. Can be effectively prevented, and thus the CD 2 and the booklet 6 can be prevented from falling.

Although not shown, the flap 17B
However, when the outer case blank 7B is folded and the outer case 4 is assembled, the outer case blank 7B functions to cover the inner case insertion opening 5 and prevents the inner case 3 from jumping out.

Further, the insertion slit 24B according to the modification example
Is formed diagonally as shown in FIG.

According to the insertion slit 24B, the flap 17B can be easily inserted when it is inserted.

FIGS. 23 to 25 show still another modified example of the flap 17. The flap 17C according to this further modification is different from the flap 17 according to the above-described embodiment in that the direction of the arc-shaped cut line formed in the insertion portion 19 is changed to the cut line 2 that opens rearward.
2 ′ (see FIG. 23).

Therefore, by forming the cut line 22 ', a flat pressed piece 23' extending forward is formed. The "front" and "rear" herein are the states in which the two folding lines 13g and 13h of the flap 17C are both bent at 90 [deg.] And the cover 21 covers the inner case insertion opening 5 (see FIG. 25). .

The flaps 17C are not inserted into the insertion slits 24 of the bottom panel 9, but are inserted into the insertion slits 25 ', 25' formed therebetween by the formation of the orthogonal slits 25, 25, 25. Is inserted into the cut line 22 'of the flap 17C from the back side (see FIG. 24).

That is, in the above-described first embodiment, the insertion portion 19 of the flap 17 is inserted into the insertion slit 24, but in this modification, the flap 17
The pressed piece 23 'is slightly raised from the front side to the back side so as to widen the cut line 22' of C, while the insertion piece 25 ',
The insertion slit 24 is widened such that the insertion slit 25 is slightly raised from the inside to the outside, and the insertion pieces 25 ′ and 25 ′ are inserted into the cut line 22 ′ from the back side of the flap 17 C. The pressing piece 23 'is pressed.

With such a configuration, the state in which the inner case insertion opening 5 of the outer case 4 is covered by the flap 17C can be more simply maintained, and the convenience can be improved (see FIG. 25).

FIGS. 26 to 31 show a storage case according to a second embodiment of the present invention.

The second embodiment is different from the first embodiment in that a window, a sealing flap and the like are provided in a storage case. In addition, the description is made only for the above difference, and the other parts are the same as the reference numerals assigned to the same parts in the storage case (CD case 1) according to the first embodiment in each part of the drawing. The description is omitted by attaching the reference numerals.

A rectangular window (hereinafter, referred to as “opening”) is located at a position slightly behind the center of the upper surface panel 8 and the right side panel 10r of the CD case 1A in the front-rear direction.
It is called the “number confirmation window”. 2) 38 are formed.
6). Incidentally, the "number confirmation window 38" is described in claim 1.
