In order to protect such a disk from damage and theft, there is a storage case that is bound together with a book (see, for example, Patent Document 1). In this storage case, a disk is sandwiched between cardboards. When the disk is first taken out, it is cut and opened along the perforation provided on the cardboard.
JP-A-8-2572

  If you wrap the disc case with film, you won't be stolen by removing the disc from the disc case unless you break the package and open it, but before you buy a CD or DVD, put it in the disc case. It is not possible to view the booklet.

  In addition, a storage case that is bound to a book, a magazine, or the like has a poor appearance after being unsuccessfully opened along the perforation provided on the cardboard. Further, since the lid is raised in the direction of raising the paper surface, if the opening and closing are repeated, the shape of the cardboard is formed and the lid is not closed, and the disk is not well protected and stored.

  Therefore, an object of the present invention is to provide a disc case with an anti-theft piece that prevents the removal and theft of a disc attached to the publication without obstructing browsing of the portion of the publication.

  The disc case with an anti-theft piece according to the present invention includes a storage portion, a holding claw, a notch, a closing member, a locking piece, and a coupling piece. The storage portion is recessed according to the outer shape of the disk. The holding claw projects from the outer peripheral edge of the storage portion toward the center and engages with the edge of the disk that is received in the storage portion. The notch portion is formed on the outer side from the outer peripheral edge of the storage portion so that a finger can be put on the edge of the disc received in the storage portion. The closing member covers the notch and is detachably mounted. The locking piece extends from the closing member toward the inside of the storage portion and stops the movement in the take-out direction in which the edge of the disk is lifted from the storage portion. The coupling piece extends outward from the outer peripheral edge of the storage portion and restricts the movement of the closing member in the take-out direction.

  In this case, in order to prevent the closing member from being easily removed from the notch unless the opening operation is performed, the closing member includes a frame portion that fits the coupling piece, and a blocking plate that blocks the opening of the frame portion. With. In order to facilitate the opening operation for removing the closing member from the notch, a part of the closing member is provided with a knob that is picked during the opening operation.

  In order to facilitate the opening operation, the closing plate is supported on the inner peripheral surface of the frame portion by two inclined portions. Further, the outer periphery of the closing plate is connected to the frame portion at at least one connecting portion other than the tilting portion, and the connecting portion is broken by the opening operation. The knob is provided on one side of the closing plate with the swing axis connecting the tilting portions as a boundary, and is pushed out of the other side of the closing plate to protrude from the frame portion. The closing plate has flexibility and gradually decreases in thickness as it approaches the swing axis from the knob.

  In order to hold the disc more securely, the at least one holding claw is provided on a support portion that is displaceable in the radial direction of the disc received in the storage portion and urges toward the inside of the storage portion. The members are arranged in a range that is symmetrical via the disc with respect to the holding claws that are urged in the radial direction toward the inside of the storage portion. In addition, a sealing piece is attached to the center hole of the disk so that the finger stored on the disk stored in the storage unit cannot be caught. The sealing piece is mounted from the storage unit side and closes the center hole. In particular, the sealing piece is loosely fitted in the center hole so as not to distort the disk.

  According to the disc case with the anti-theft piece according to the present invention, the notch portion formed on the outer peripheral edge of the storage portion is covered with the closing member so as to put a finger on the disc, so that the disc can be easily removed from the storage portion. Can not. That is, it is possible to prevent the disk from being stolen. In addition, a coupling piece that restricts the movement of the closing member in the direction of taking out the disk from the storage portion is provided. That is, the closing member and the storage portion are structurally engaged. Therefore, the positional relationship between the storage portion and the closing member is determined stably and does not vary from product to product.

  Since the closing member includes a frame portion and a closing plate, the disc anti-theft piece is firmly fixed to the cutout portion and cannot be removed unless an opening operation is performed. Since the closing plate is supported by the frame portion at two tilting portions, the other easily protrudes when one is pushed in with the swing axis connecting the tilting portions as a boundary. When the opening operation is performed, the closing member is removed from the notch with the protruding side as a knob. As a result, the disc case with the anti-theft piece is in an opened state in which the disc can be easily taken out.

  The closing plates are connected by at least one connecting portion other than the tilting portion. Since this connection part is cut | disconnected by performing opening operation, it can be discriminate | determined whether fraudulent act was performed. In addition, the closing plate has flexibility, and the plate thickness is gradually reduced as it approaches the swing axis from the knob. Therefore, after the knob is protruded by an opening operation, the tab is further raised and picked. The part can be easily picked. Moreover, since the closing plate has flexibility, the closing member can be removed from the cutout portion without losing the closing plate by the opening operation.

  Further, according to the disk case with an anti-theft piece further including a sealing piece attached from the storage unit side to the center hole of the disk stored in the storage unit, the notch is blocked and the center hole of the disk is also blocked. . That is, since there is no portion where a finger can be hung to take out the disc, the disc cannot be easily removed from the storage portion. Therefore, the theft of the disk can be prevented more reliably.

  The publication including the disc case with the anti-theft piece according to the present invention cannot remove the disc unless an opening operation for removing the anti-theft piece is performed. Therefore, since there is no worry that the disc can be pulled out, the publication can be placed in the store in a state where it can be freely browsed, and the purchase applicant is not prevented from browsing the portion of the publication freely. Further, the purchaser can easily take out the disc by removing the disc anti-theft piece by the opening operation, and can use the disc case as a storage location of the disc.

  A disc case with an anti-theft piece according to an embodiment of the present invention will be described with reference to FIGS. 1 to 9, taking as an example a disc case 1 formed on a part of a bound book 100. A disc case 1 shown in FIG. 1 includes a storage portion 2, holding claws 3 a, 3 b, 3 c, a cutout portion 4, and a disc theft prevention piece 5.

  The cutout portion 4 and the disc antitheft piece 5 are arranged at positions symmetrical to each other via the disc 200 with respect to the holding claws 3 a that are urged in the radial direction toward the inside of the storage portion 2. The disc antitheft piece 5 is removed from the notch 4 by a series of opening operations shown in FIGS.

  The storage unit 2 is recessed in accordance with the outer shape of the disc 200 from the inside of the cover 101 of the book 100, from the side of the paper surface 101a corresponding to the so-called "Table 2" or "Table 3". In one embodiment, the cover 101 of the book 100 has a sufficient thickness to enclose the disc case 1. The disc 200 placed in the storage unit 2 is a disc-shaped information recording medium in which recorded information is read by an optical reading means. Specifically, the disc 200 is a compact disc (CD), a single CD, a digital video disc. (DVD).

  The holding claws 3 a, 3 b, 3 c protrude from the outer peripheral edge 2 a of the storage portion 2 toward the center and engage with the edge 201 of the disk 200 placed in the storage portion 2. In one embodiment, the holding claws 3a, 3b, 3c are provided at three positions, and one of the holding claws 3a is displaced in the radial direction and is urged toward the inside of the storage portion 2. . As a result, the disk 200 is held in the storage unit 2 without rattling. The notch portion 4 is formed in the radial direction from the outer peripheral edge 2 a of the storage portion 2 toward the outside of the storage portion 2 so as to put a finger on the edge 201 of the disk 200 stored in the storage portion 2.

  As shown in FIGS. 2 and 3, the disk theft prevention piece 5 includes a closing member 6 and a locking piece 7. The closing member 6 covers the notch 4 and is detachably mounted. The locking piece 7 extends from the closing member 6 toward the inside of the storage unit 2, and the movement of the edge 201 of the disk 200 in the take-out direction that lifts from the storage unit 2 is stopped. The disc case 1 has a coupling piece 15 that fits into the storage portion 2 and the disc anti-theft piece 5. The coupling piece 15 extends along the inner side surface of the cutout portion 4 facing outward from the outer peripheral edge 2 a of the storage portion 2. The coupling piece 15 has a bar-like locking portion 15 a on the outer surface along a plane in which the disk case 1 extends, and is fitted to the inner surface of the notch portion 4. Further, the coupling piece 15 has a concave portion 15b formed on the inner surface along a plane in which the disk case 1 extends.

  The closing member 6 includes a frame portion 8 and a closing plate 9. As shown in FIG. 2, the frame portion 8 is formed along the inner surface of the cutout portion 4 and the coupling piece 15. As shown in FIG. 4, a locking projection 8 b that engages with the recess 15 b is provided on the outer surface 8 a of the frame portion 8 adjacent to the coupling piece 15. When the recess 15b and the locking projection 8b are fitted, the movement of the closing member 6 in the take-out direction R is restricted. In addition, the relationship between the recessed part 15b and the latching convex part 8b may be formed reversely. That is, the engaging protrusion 15 may be formed on the coupling piece 15 and the recess may be formed on the frame 8.

  As shown in FIG. 3, the closing plate 9 is provided so as to block the opening 10 of the frame 8 near the paper surface 101 a inside the cover 101. The closing plate 9 is supported on the inner peripheral surface 8 c of the frame portion 8 by tilting portions 11 provided at two locations along the edge 201 of the disk 200.

  A knob portion 13 is provided on the disk 200 side with a swing axis 12 connecting the two tilting portions 11 as a boundary. On the outer periphery 9a of the closing plate 9, an end 9b opposite to the knob 13 with respect to the swing axis 12 is connected to the frame 8 by a connecting portion 14 that is broken by an opening operation. Further, the closing plate 9 is formed so that the plate thickness gradually decreases as it approaches the swing axis 12 from the knob 13.

  The material forming the disc anti-theft piece 5 has flexibility (toughness) to such an extent that the tilting portion 11 is not threaded or cracked in the closing plate 9 by the opening operation, and the knob portion 13 is picked. It is preferable to have such rigidity that it cannot be removed unless it is pulled out. Specifically, polypropylene, polystyrene mixed with rubber resin, polyethylene, polyvinyl chloride, vinyl chloride vinyl acetate copolymer, polymethyl methacrylate, polymethylstyrene, polyurethane, polycarbonate, polyoxymethylene Etc. can be used. Further, the disk theft prevention piece 5 can be made at a lower cost if it is integrally formed by injection molding.

  In the disk case 1 configured as described above, as shown in FIG. 5, the disk theft prevention piece 5 is attached to the coupling piece 15 and the notch 4 is closed. Therefore, it is impossible to put a finger on the edge 201 of the disk 200 stored in the storage unit 2. Since the storage unit 2 and the disk theft prevention piece 5 are connected by the coupling piece 15, the positioning accuracy of each other is good. Further, the locking piece 7 is provided at a position that is symmetrical with respect to the holding claw 3a with the disc 200 interposed therebetween, and is formed longer than the displacement amount of the holding claw 3a, so that the disc 200 is opposed to the urging force. The disk 200 does not fall out of the storage unit 2 even if it is shifted in the direction of the holding claw 3a.

  That is, the disk 200 cannot be removed. In addition, the disc case 1 is provided inside the cover 101 of the book 100 and only removes the disc 200 from the storage unit 2 so that it is difficult to steal. Therefore, the book 100 is opened in this state and the inside can be freely viewed. can do. As described above, the disc case 1 to which the disc anti-theft piece 5 is attached can prevent the disc 200 from being stolen without hindering browsing the book 100.

  Next, the opening operation of the disk case 1 will be described with reference to FIGS. In the state shown in FIG. 6, the notch 4 is completely covered by the disc anti-theft piece 5 and a finger cannot be put on the edge 201 of the disc 200. As shown in FIG. 7, the unsealing operation is performed first with the finger in the thickness direction of the cover 101 as shown by the arrow in FIG. 7 at the end 9b of the closing plate 9 far from the disc 200 with respect to the swing axis 12. Push in. Then, the connecting portion 14 is broken, the tilting portion 11 is used as a fulcrum, the plate 9 is tilted, and the knob portion 13 is lifted from the frame portion 8. The lifted knob 13 is further raised with a finger as shown in FIG. Finally, the knob portion 13 is picked with a finger and the disc anti-theft piece 5 is pulled out from the cutout portion 4 as shown in FIG.

  As described above, the series of opening operations shown in FIGS. 7 to 9 can be easily performed with one hand. Moreover, since the connection part 14 is fractured once opened, the distinction from the unopened one is obvious. Further, the disc anti-theft piece 5 is completely removed from the cutout 4 without leaving any residue. Further, the disc anti-theft piece 5 is not engaged with the cutout portion 4 but is fitted with a coupling piece 15 extending from the storage portion 2. Therefore, the disc theft prevention piece 5 is not pulled out, so that the inner peripheral surface of the notch 4 is not damaged. The cutout 4 is a portion provided for putting a finger on the edge 201 of the disc 200, and thus does not impair the appearance. Even after opening, the disk case 1 can store the disk 200 in a preferable state without impairing the function of the disk 200 as a storage location.

  By the way, in this embodiment, the disc 200 is held by the storage portion 2 with the edge 201 locked by the holding claws 3a, 3b, 3c, and the center hole 202 provided in the center of the disc 200 is opened. It is in the state. Therefore, the removable sealing piece 16 is attached as shown in FIG. 10 so that the finger can not be put on the center hole 202 until it is opened. The sealing piece 16 is formed in a hat shape and is attached to the disk 200 from the side facing the storage portion 2. In particular, it is preferable that the sealing piece 16 attached to the DVD is loosely fitted to the center hole 202 so as not to distort the disk 200. Thus, by attaching the sealing piece 16 to the center hole 202, it is further difficult to take out the disc 200 from the storage portion 2 and to prevent theft.

  In the present embodiment, when a plurality of cutout portions 4 are provided, a coupling piece 15 extending from the storage portion 2 is provided in each cutout portion 4 and the disc antitheft piece 5 is attached. Further, the disk case with the anti-theft piece in which the anti-theft piece 5 is mounted on the storage unit 2 of the type that clamps the disk on the outer periphery has been described as an example. However, a disc case with an anti-theft piece in which the disc anti-theft piece 5 is mounted in a center clamp type storage portion that fits into the center hole 202 of the disc 200 may be used.

  Even in this case, the disc case 1 can prevent the disc 200 from being stolen by attaching the disc anti-theft piece 5 to the cutout portion 4 provided outward from the outer peripheral edge 2a of the storage portion 2. Further, the knob 13 may be provided in a part of the closing plate 9 on the side farther from the disc 200 than the swing axis 12. In this case, by pushing the end of the closing plate 9 closer to the disc 200 than the swing axis 12, the knob 13 is lifted from the frame 8, so that the knob 13 is further raised and the knob 13 is picked. Thus, the disc anti-theft piece 5 may be removed from the cutout 4.

  In addition, if the knob | pick part 13 is formed in the closing member 6 so that the said part can be picked and the disk antitheft piece 5 can be removed, it will incline around the rocking | fluctuation axis line 12 which connects the inclination part 11 as mentioned above.
