Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a disk protection case structure for detachably holding a disk such as a compact disk (CD).

[0002]

[Prior art]

 Discs (recording media) typified by compact discs for music (CDs) and CD-ROMs such as personal computer software and game software are usually stored in disk protection cases for storage, carrying, transport, or display. Is done.

As can be seen from FIG. 4, this case (disk protection case) 118 includes a bottom (back cover) 114 and a lid (front cover) 116 that are openably and closably connected by a hinge 112. . Then, a substantially cylindrical locking portion 122 that can hold the disk 120 under insertion and locking of the center hole 120a is integrally formed on the bottom 114, that is, the locking portion 122 is fixed under a fit or the like. The case 118 in the form shown in the figure, which does not have a separate tray at the bottom, is a maxi-single music CD or a low-cost CD (CD-R
OM) is provided as a simple case.

[0004]

[Problems to be solved by the invention]

 By the way, in the known simple case 118 shown in FIG. 4, the hinge end of the base 116a of the lid 116 has a substantially U-shaped cross section having a folded wall 152 that can be aligned with the base 114a of the bottom 114 when the lid 116 is closed. The card-shaped inner jacket 124 is mounted on the inner surface of the lid base, for example, with the insertion of the insertion tip into the substantially U-shaped portion. Then, the rear wall 138 of the substantially U-shaped portion is used as a title display surface or the like by bending or folding back the front end 124a of the card-shaped interior jacket.

However, it is not easy to form a substantially U-shaped portion in the lid 116, and it is necessary to extend the cooling time due to the presence of the substantially U-shaped portion, so that the molding operation becomes complicated and A delay in molding time is inevitable.

[0006] Further, the formation of the substantially U-shaped portion complicates the configuration of the mold for molding the lid 116, so that in a known case, the molding cost is likely to increase.

In a known configuration having a substantially U-shaped portion, a notch 154 corresponding to the folded wall 152 is formed in the bottom base 114a. However, by providing the notch 154 in the bottom base 114a, the hinge portion of the bottom 114 includes only the pair of side walls 130 extending opposite to each other, so that the strength of the hinge portion of the bottom is easily reduced.

Further, since the notch 154 at the bottom base is relatively wide, there is a possibility that the user may pinch a finger or the like when the case 118 is opened or closed. This pinching of fingers, etc. is not particularly problematic in terms of safety, though it is likely to hinder smooth opening and closing.

This invention aims at providing a disk protection case structure which is easy to mold and has excellent usability.

[0010]

[Means for Solving the Problems]

 In order to achieve this purpose, the role of the folded wall at the hinge end of the lid base was reviewed, and it was found that the folded wall has no particularly important role in the simple case. Based on this result, according to the present invention, the hinge end of the lid base has a substantially L-shaped cross section with the rear wall standing upright, and the rear wall is closed under the closure between the bottom and the lid. The tip is aligned and engageable with the inner surface of the hinge end of the bottom base.

[0011]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIGS. 1A, 1B and 2, in the disk protection case structure 10 according to the present invention, a combination of a bottom 14 and a lid 16 that are openably and closably connected by a hinge 12 is provided. A disk protection case 18 is formed. As can be seen from FIG. 2, a substantially cylindrical outer locking portion 22 for holding the disc 20 under insertion and locking of the center hole 20a is provided on the bottom 14, and a card-shaped interior jaw is provided. The lid 16 has a locking piece 26 for locking and holding the bracket 24, the interior book 25, etc. on the inner surface of the base 16a, and the disk protection case 18 is a disk as a recording medium, for example, for music. It is designed to be able to store and protect compact discs (CDs) and CD-ROMs such as PC software and game software in a removable manner.

This type of case (disk protection case) 18 is formed in the following form.

As shown in FIG. 2, the bottom 14 is formed in a shape in which a front wall 28 is provided on the open / close end of the base 14 a having the locking portion 22, and a side wall 30 is provided on both sides thereof. On both sides of the hinge portion of the base, hinge pieces 32 projecting from hinge pins serving as hinges 12 are erected.

On the other hand, in the lid 16, a pair of opposing side walls 34 are erected on both sides of the base 16 a, respectively, and a card-shaped interior inserted from an open / close end which is an open end having no wall. Engaging pieces 26 are provided at two locations on the side wall, that is, four locations, so that the jacket 24, the interior book 25, and the like can be engaged and held. The hinge portion of the side wall 34 of the lid 16 has, for example, a predetermined narrow stepped shape, and the bottom portion 14 is loosely fitted to a concave portion provided on the outer surface of the side wall of the narrow portion 36 by loose fitting of the hinge pin. And the lid are connected to be freely opened and closed (see FIG. 3).

Since the basic configuration of this type of case 18 is known, and the basic configuration itself is not the purpose of the present invention, a detailed description thereof will be omitted here.

Here, as can be seen from FIGS. 1 (A) and 1 (B) in addition to FIG. 2, in the present invention, the hinge end of the lid base 16a is formed in a cross-section where the rear wall 38 is erected. The rear wall tip 38a is aligned and engageable with the inner surface of the hinge end of the bottom base 14a under the closure between the bottom 14 and the lid 16, with the L-shape being substantially L-shaped.

In other words, in the present invention, the hinge end of the lid base 16a has a shape obtained by removing a folded wall from a known substantially U-shaped cross section. Therefore, the molding of the lid 16 becomes easy, and in particular, the cooling time can be shortened, so that the molding stroke can be shortened.

In addition, if the lid has no substantially U-shaped portion in the present invention, the molding die can be simplified, so that the cost of the lid 16 and the case 18 can be sufficiently reduced.

Since the rear wall tip 38a can be aligned and engaged with the inner surface of the hinge end of the bottom base 14a, the strength of the hinge end can be obtained sufficiently high, and the entry of dust and the like is sufficient. Can be prevented.

Further, according to the present invention, a wide-range notch is not formed at the hinge end of the bottom base 14a, and the hinge end of the bottom base is aligned with the rear wall tip 38a of the lid. The finger can be reliably prevented when the lid is opened and closed. Therefore, the lid 16 can be opened and closed smoothly, and thus the case 18 can be opened and closed smoothly, whereby the usability of the case is reliably improved.

Since the hinge piece 32 is not independent from the bottom base 14a in a wide range, it is sufficient that the notch 40 for obtaining its elasticity is provided in the bottom base, so that the strength of the hinge portion of the bottom 14 is ensured. (See FIG. 3).

In the present invention, with the shape of the lid 16 having no substantially U-shaped section at the hinge end, the card-like interior jacket 24 cannot be locked and held at the hinge end. However, since the card-shaped interior jacket 24 can be locked and held by the locking pieces 26 on the side walls, the card-shaped interior jacket 24 does not have a substantially U-shaped portion at the hinge end. The falling off of the jacket can be reliably prevented.

As shown in the figure, if the front end 24a of the card-like interior jacket 24 is bent and inserted, the rear wall 38 of the hinge end side of the lid can be easily used as a title display surface as in the related art. It is possible.

That is, according to the present invention, the usability of the case 18 can be easily improved without impairing the functionality.

Here, as shown in FIGS. 2 and 3, it is preferable that the rear wall 38 of the lid is integrally connected to the pair of side walls 34. According to such a configuration, since the strength of the rear wall 38 and the side wall 34 is increased, the rigidity of the lid 14 and the case 18 can be easily enhanced. Further, by enhancing the rigidity of the case 18, the functionality of the case for protecting the disk 20 is further improved.

In the case 18 of this type, the hinge portion of the side wall 34 of the lid 16 is formed as a narrow portion 36, and the bottom hinge piece 32 is disposed in the narrow portion, thereby protruding from the case outer periphery. The elimination of parts has been attempted. Then, in the present invention, as shown in FIG. 3, the insertion of the card-shaped interior jacket 24 can be ensured between the pair of stepped ends 36a projecting inward of the side wall 34 by forming the narrow portion 36, and The width is set so as to be engageable with the insertion tip corner 25a of the interior book 25.

According to such a configuration, the card-shaped interior jacket 24 can be inserted and arranged without being hindered by a locking end or the like for the interior book 25, and the interior book is appropriately positioned at the arrangement position. Therefore, it is possible to easily install the card-shaped interior jacket and the interior book without complicating work and arrangement.

In the case where the card-shaped interior jacket 24 is omitted and the cover of the interior book 25 is also used as the interior jacket, as shown by a two-dot chain line in FIG. 2 and FIG. It is preferable that the engagement protrusion 42 at the insertion tip be engageable with the inner surface of the lid base 16a. With this configuration, the insertion tip of the interior book 25 is prevented from being advanced not only at the corners 25a but also at the entire portion thereof, so that the interior book 25 is not excessively moved toward the hinge edge. Intrusion is more reliably prevented.

Therefore, the positioning of the interior book 25 is further facilitated and assured.

The embodiment described above is for explaining the present invention, and does not limit the present invention in any way, and all the modifications and alterations within the technical scope of the present invention are included. It goes without saying that this invention is included in the invention.

[Effect of the invention]

 As described above, according to the disk protective case structure according to the present invention, the lid has a shape that does not have a substantially U-shaped cross section at the hinge end, so that the lid can be easily formed, and in particular, the cooling can be achieved. Since the time can be shortened, the molding stroke can be shortened. If the lid shape does not have a substantially U-shaped portion, the mold for molding can be simplified, so that the cost of the lid and thus the case can be sufficiently reduced.

In addition, since the front end of the rear wall is aligned and engaged with the inner surface of the hinge end of the bottom base, the strength of the hinge end can be obtained sufficiently high and dust can be sufficiently prevented from entering.

Furthermore, a wide-range notch is not provided at the hinge end of the bottom base, and the hinge end of the bottom base is extended to a position aligned with the rear wall of the lid. Pinching or the like can be reliably prevented. Therefore, the lid can be opened and closed smoothly, and thus the case can be opened and closed smoothly, whereby the usability of the case is reliably improved.

Further, since the hinge piece is not independent from the bottom base in a wide range, it is sufficient to provide a cut in the bottom base for obtaining its elasticity, and the strength at the hinge end side of the bottom is reliably enhanced. .

In addition, by integrally connecting the rear wall of the lid to the pair of side walls, the strength of the rear wall and the side walls is increased, and the rigidity of the lid can be enhanced. Be improved.

Furthermore, by providing a width between a pair of stepped ends protruding inwardly of the side wall so as to ensure insertion of the card-shaped interior jacket and to be able to engage with a corner of the insertion end of the interior book, the card-shaped interior is formed. Since the jacket can be easily inserted and arranged, and the interior book is properly positioned at the location, it is easy to attach the card-shaped interior jacket and interior book without complicating the work and layout. Can be secured.

[0038] Further, if the engagement protrusion at the insertion end of the interior book is protruded from the inner surface of the lid base, the card-like interior jacket can be omitted and the cover of the interior book can be used as the interior jacket. In addition, the positioning and positioning of the interior book will be easier and more reliable.
