Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technical field relating to a folding structure of a storage case for discs which holds and folds discs such as CDs (compact discs) and DVDs.

[0002]

2. Description of the Related Art Conventionally, as a storage case for disks having a folding structure, for example, one disclosed in Japanese Patent Publication No. 7-14743 is known.

As shown in FIGS. 23 and 24, this conventional storage case for disks includes a mount 1 on which one sheet of paper is adhered with a folding adhesive 5 and folded in three, and a mount. It is composed of a holder 2 which is fixed to one surface of an inner side paper 11 which is an inner side of the folding of No. 1 and which holds the discs D in a releasable manner.
The folding line of the inner paper 11 of the mount 1 is composed of a band-shaped cut 3 which is cut out over the entire line. In addition, the folding line of the outer side paper 12 of the mount 1 is composed of a band-shaped groove 4 which is narrower than the notch 3 in which the paper thickness is reduced over the entire line. The width of the band shape of these notches 3 and grooves 4 ensures the thickness of the holder 2 and the folding margin of the mount 1.

In this conventional storage case for disks,
Since the notch 3 and the groove 4 can absorb the crease formation stress generated in the mount 1 when the mount 1 is folded and expanded, the fold 1 can be smoothly folded and expanded without forming creases. Further, since the mount 1 is formed by folding one sheet of paper material, it is possible to perform design processing such as printing and decoration in advance except for the notch 3 on the inner surface of the paper material.

[0005]

In the above-mentioned conventional case for storing disks, since the notch 3 and the groove 4 increase the structural missing portion in the folding line, folding and unfolding are repeated many times. However, there is a problem that it is easily damaged and has low durability. Furthermore, since the paper material forming the mount 1 must be made thicker in order to form the groove 4, there is a problem in that the storage exterior becomes thicker.

The present invention has been made in consideration of the above problems, and provides a storage case for discs, which has a compact storage housing and has improved durability without lowering the smoothness of folding and unfolding. The task is to do.

[0007]

In order to solve the above-mentioned problems, a storage case for disks according to the present invention adopts the following means.

That is, according to the first aspect of the present invention, a sheet of paper which is folded and adhered to form a sheet of paper and is folded into at least two folds, and a disk which is fixed to at least one surface of an inner sheet which is an inner side of folding of the sheet of paper. In a storage case for disks, which comprises a holder for detachably holding items, the fold line of the mount is formed by two parallel fold lines, and a non-notched part is left in part along the fold line of the inner paper of the mount. It is characterized by notching two parallel slits.

According to this means, the two slits absorb the forming stress of the crease similarly to the notches and grooves of the conventional example, but the two slits absorb the stress especially in correspondence with the two fold lines. At the same time, the space between the folding lines is strengthened by the inner paper left between the two slits. The non-cutout portion remaining on the folding line can secure the structural strength of the folding line and can thin the paper material forming the mount. Further, since the mount does not have a notch as in the conventional case, it is possible to continuously perform design processing such as printing and decoration on the inner side paper.

Further, according to a second aspect of the present invention, a disc mount is formed by folding and adhering one sheet of paper material into at least two folds, and at least one surface of the inner paper which is an inner side of the folding of the mount sheet and is fixed to the disc. In a storage case for disks, which includes a holder that detachably holds items, the fold line of the mount is formed by two parallel fold lines, and one side in the length direction of the area surrounded by both fold lines of the inner paper of the mount is formed. It is characterized in that one slit is cut out leaving a non-cutout part in the part.

According to this means, the widely cut slit absorbs the crease forming stress in the same manner as the conventional notch and groove. The non-cutout portion remaining on the folding line can secure the structural strength of the folding line and can thin the paper material forming the mount.

According to a third aspect of the present invention, in the storage case for discs according to the first or second aspect, the non-cutout portions are provided at both ends of the folding line of the inner paper of the mount.

By this means, both ends of the fold line of the inside paper of the mount, on which the stress for forming creases is likely to concentrate, are structurally reinforced.

According to a fourth aspect of the present invention, in the storage case for discs according to any of the first to third aspects, the notch end of the slit in the folding line direction is arcuate.

By this means, damage due to stress concentration from the notch end of the slit can be prevented.

According to a fifth aspect of the present invention, in the storage case for discs according to any one of the first to fourth aspects, a perforation is provided in a portion of the inside paper of the mount, which is left without cutting the slit of the folding line. Characterize.

This means has a function of absorbing crease forming stress while reducing structurally missing portions of the folding line.

Further, in a sixth aspect of the present invention, in the storage case for discs according to any of the first to 45th aspects, a streak is provided in a portion of the backing paper inside which the slit of the folding line is left without being cut out. And

By this means, it is possible to easily fold and unfold the portion left without being cut out by pressing the streaks, while preventing the formation of wrinkles in an unexpected direction.

According to a seventh aspect of the present invention, in the storage case for discs according to any of the first to sixth aspects, a streak is provided on the fold line of the outer paper of the mount.

By this means, it is possible to prevent the formation of wrinkles in the unexpected direction on both the inside paper and the outside paper of the mount.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a storage case for disks according to the present invention will be described below with reference to FIGS.

1 to 9 show an embodiment (1) of a storage case for disks according to the present invention.

In this embodiment, as in the case of the above-mentioned conventional example, the mount 1 is folded in three.

As shown in FIGS. 6 to 9, the mount 1 is formed by processing one rectangular paper material by the following steps. There are no particular restrictions on the material of the paper material, and since it is folded as will be described later, a fairly thin material can be selected.

First, as shown in FIG. 6, the rectangular paper material is subjected to design processing 6 such as continuous printing and decoration on the portion other than the portion to which the holder 2 is fixed. As the design processing 6, a description of the contents of the disc D, printing of an image, or decoration of various patterns can be considered. The design processing 6 is applied only to the surface of the paper material. The back surface of the paper material is an adhesive surface that is folded and bonded as described later. In the present embodiment, in addition to bonding with an adhesive,
Polymerization means such as pressure bonding can be used depending on the paper material.

The two folding lines of three folds, which are the lines that reach the longitudinal sides 1a at the boundary between the portion of the paper material that has been subjected to the design processing 6 and the portion that has not been processed, are shown in FIG. In addition, it is composed of two parallel fold lines La and Lb with a space therebetween which secures the thickness of the holder 2 and the folding margin of the mount 1.
The folding lines La and Lb are formed by two parallel streak pushers 20 as shown in FIG. Therefore, the distance between the fold lines La and Lb is defined by the difference in the folding margin due to the folding and stacking of three folds
It will be different on the left and right sides of the drawing.

In each of the folding lines La and Lb, two slits 7 are cut out by punching or the like in a portion of the paper material where the design processing 6 is not applied. As shown in detail in FIGS. 2 and 3, these parallel slits 7 are cut out leaving non-cutouts 8 at both ends, and cutouts 71, 72 in the directions of fold lines La, Lb are arc-shaped. Is formed in. In addition, the non-cutout portion 8 has perforations 9 on the folding lines La and Lb, respectively.
The streak pusher 10 is cut and pressure-formed. However, these parallel perforations 9 are not communicated with the slit 7 and the long side 1a of the paper material, respectively. Further, a streak pusher 20 having a pressurizing direction opposite to that of the streak pusher 10 is formed on the remaining portion on the folding lines La and Lb (the portion on which the design processing 6 of the paper material is applied). Furthermore, the slit 7 is located on the same line as the upper portion of the streak pusher 20 and is preferably formed to be slightly wider than the streak pusher 20.

As shown in FIG. 8, the paper material on which the folding line composed of the two parallel folding lines La and Lb is processed is coated with the adhesive 5 on the back surface from the center of the short side 1b. Two mountain folds are bonded along a straight line Lc extending in the longitudinal direction.
At this time, the portion surrounded by both slits 7 is the spacer piece 3
It remains 0 and the spacer piece 30 can be formed as a non-coated portion without coating the adhesive 5. Of course, although not shown, it is also possible to bond it to the spacer piece 30.

The backing sheet 1 formed by the above processing is the inner sheet 11 on the inside of the fold on the side where the slits 7 are provided, and the outer sheet 12 on the opposite side on the outside of the fold. Then, as shown in FIG. 9, the holder 2 is fixed to the central portion of the inner paper 11.

According to this embodiment, the mount 1 is folded or unfolded from both sides of the holder 2 by the two folding lines which are each constituted by the two folding lines La and Lb. At the time of folding and unfolding, since the crease forming stress generated in the mount 1 can be absorbed by the slits 7, respectively, the folds can be smoothly folded and unfolded without forming creases. Further, the provision of perforations 9 in the non-cutout portion 8 where the slit 7 is not cutout also contributes to improvement in smoothness of folding and unfolding. Also, the non-cutout portion 8
The streak pusher 10 provided on the outside and the streak pusher 20 provided on the outer side paper 12 also guide the folding direction to prevent the formation of wrinkles in an unexpected direction and contribute to the improvement of smoothness of folding and unfolding. .

When the mount 1 is folded, a thin paper material can be selected for the mount 1, so that the housing is thin and compact. Therefore, it can be inserted and wrapped in a plastic case in a folded state. In addition,
When a pressing force acts on the backing sheet 1 due to this encapsulation structure and other factors, the crushing force applied to the folding line is applied to the inner side sheet 11
Then, since the outer paper 12 which is absorbed by the slit 7 and the crushing force is not absorbed and the spacer piece 30 which is a non-adhesive portion, the integrity is released, so that the portion (back portion) of the inner paper 11 between the slits 7 is formed. Wrinkles and curved surfaces do not occur. Therefore, the appearance in the expanded state can be well maintained.

Even when the backing sheet 1 is repeatedly folded and unfolded as described above, the non-notched portions 8 are provided at both ends of the slit 7 so that the inner sheet 11 has a structural strength. Since the concentration of the breaking stress on the outer paper 12 is avoided, it is not easily broken and high durability can be obtained. Further, the fact that the cutouts 71, 72 of the slit 7 are arcuate and the breaking stress is less likely to concentrate also contributes to the improvement of durability. Further, the fact that the slit 7 is provided along the two folding lines La and Lb and is not cut into an area larger than necessary also contributes to the improvement of durability. Further, the fact that the perforations 9 do not communicate with the slit 7 and the long side 1a of the paper material is also effective in preventing damage.

FIG. 10 shows an embodiment (2) of a storage case for disks according to the present invention.

In this embodiment, a plurality of slits 7 and non-cutout portions 8 are provided in each of the folding lines La and Lb. The non-cutout portion 8 is preferably a fold line L of the inner paper 11.
It is left near both ends of a and Lb.

According to this embodiment, since the number of non-cutout portions 8 arranged is increased, the durability is improved as compared with the above-mentioned embodiment (1). Therefore, the slits 7 at both ends communicate with the long side 1a of the mount 1, but there is no disadvantage in terms of durability.

FIG. 11 shows an embodiment (3) of a storage case for disks according to the present invention.

In this embodiment, the perforations 9 provided in the non-cutout portion 8 of the fold line La or Lb are provided along the edges of the streak pusher 10 along the extension line of the long side of the slit 7, respectively. It has a column structure.

According to this embodiment, the line pressing member 10 sandwiched between the two rows of perforations 9 which absorbs the crease formation stress.
The linearity is ensured and the folding direction is accurately guided.

12 to 20 show an embodiment (4) of a storage case for disks according to the present invention.

In this embodiment, one slit 7 in the above-mentioned embodiment (1) is formed widely by notching by punching in a region surrounded by both folding lines La and Lb. In addition, the slit 7 is formed by the two folding lines La and Lb.
It is also possible to make a notch by slightly expanding it to the outer side of the, i.e., the outer side of each streak 20. Further, the manufacturing process, folding, and unfolding use are the same as those in the above-mentioned embodiment (1). However,
When the adhesive 5 is applied to the back surface of the paper material and the two mountain folds are bonded as shown in FIG. 19, the adhesive 5 is not applied to the portion facing the slit 7.

According to this embodiment, the same operation and effect as those of the above-mentioned embodiment (1) can be obtained. Further, the widely cut slits 7 can surely absorb the crease forming stress generated in the mount 1 at the time of unfolding. Further, since the slit 7 is widely cut out, the decorativeness can be enhanced by subjecting the portion of the adhesive surface of the outer paper 12 of the mount 1 facing the slit 7 to a design process 6.

FIG. 21 shows an embodiment (5) of a storage case for disks according to the present invention.

In this embodiment, the above-mentioned embodiment (4) is modified corresponding to the above-mentioned embodiment (2). That is, in this embodiment (5), each broken line La, L
In b, a plurality of slits 7 and a plurality of non-cutout portions 8 are provided in a wide width. The non-cutout portion 8 is preferably the inner paper 11
It is left in the vicinity of both ends of the polygonal lines La and Lb.

According to this embodiment, the same operation and effect as those of the above-mentioned embodiments (2) and (4) can be obtained. That is, since the number of non-cutout portions 8 arranged increases, the durability is improved.

FIG. 22 shows an embodiment (6) of a storage case for disks according to the present invention.

In this embodiment, the above-mentioned embodiment (4) is modified corresponding to the above-mentioned embodiment (3).

According to this embodiment, the same operation and effect as those of the above-mentioned embodiments (3) and (4) are exhibited.

As described above, in addition to the illustrated embodiment, the mount 1
It is also possible to adopt a structure in which is folded in two or four or more.

It is also possible to fix two or more holders 2 to the mount 1.

Further, although not shown, it is possible to adopt a structure in which the perforations 9 and 20 are provided without providing the perforations 9 in the non-cutout portion 8. In this case, the smoothness of folding and unfolding at the folding lines La and Lb is not impaired.

Further, it is possible to omit the line pressing 10, 20. Since a thin paper material can be used for the mount 1 and is on the extension line of the slit 7, the smoothness of folding and unfolding at the folding lines La and Lb is not impaired.

[0053]

As described above, since the storage case for disks according to the present invention can absorb the forming stress of creases by the slits, the mount can be folded and unfolded smoothly, and the slits are notched. Since the structural strength can be secured by the portion that has not been formed, there is an effect that durability is enhanced.

Further, since the mount can be formed of a thin paper material, there is an effect that the housing is made compact.

Further, according to claim 1 of the present invention only,
Since the inner side paper is present between the two slits, it is possible to perform continuous printing and design processing such as decoration, and at the same time, it is possible to strengthen the streak gap.
