DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single-size CD or the like, in which a CD case containing a security tag is housed, and a single CD or the like which can be locked by a lock mechanism so that the CD case cannot be removed. The present invention relates to a storage container.

[0002]

2. Description of the Related Art Conventionally, a security tag which reacts magnetically or electrically is attached to a product such as a CD or a video tape so as to prevent the product from being illegally taken out of a store. But,
When attached directly to a product, the security tag could be peeled off or cut off. In order to solve this problem, a security tag and a CD or the like are put in a container that can be locked in a case. When the product is sold, the lock is released and only the cased product is taken out of the storage container and delivered to the customer.

However, a lock mechanism for a storage container that has been conventionally used uses a cylinder lock or a tumbler lock and locks / unlocks with a key. These lock mechanisms are used depending on the application. However, in a configuration in which a store such as a CD shop or a video rental shop is locked to prevent shoplifting, one type of key is used. It has been desired that a store clerk can unlock many locks quickly. In view of this, as disclosed in Japanese Patent Application No. 8-144006, there has been proposed an unlocking device that includes a leaf spring and a lock member that are urged in one direction and that has a magnet and is unlocked by a clerk.

[0004]

However, in the case of a single CD having a diameter of 8 cm, the CD case main body is made of synthetic resin, but the lid has a simple structure made of paper. For this reason, a storage container having a large opening through which a CD case can be taken in and out of the rear surface has low strength, and it is difficult to securely store the CD case. Also, in a conventional storage container having a lock mechanism biased from one direction by a single leaf spring, all locks can be opened with an unlocking device having a magnet on one side. It is convenient, but there is a risk that an unauthorized customer may be released by approaching the lock mechanism while holding the magnet in hand and attracting a leaf spring to search for an open side, and the product may be illegally taken out. There was a point.

SUMMARY OF THE INVENTION In view of the above-mentioned problems of conventional storage containers such as case-containing CDs, it is an object of the present invention to securely hold a case of a single CD having a weak strength and to illegally lock a magnet by holding a magnet in a hand. It is an object of the present invention to provide a storage container such as a case-containing CD that cannot unlock a CD.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a storage container body having an opening through which a CD case can be taken in and out by sliding to one side end, and a storage container body attached to the storage container body. A lock mechanism that acts on a part of the opening to restrict the insertion and removal of the CD case. The lock mechanism includes a locking member that can be retracted into and out of the opening, and a projecting state of the locking member. And a leaf spring disposed on both sides of an opposing surface for holding the CD.

In the lock mechanism, a guide ridge having a V-shaped cross section is formed on a locking member that comes and goes, and the leaf spring is a U-shaped one-piece magnetic material. It is formed by bending.

In the case of a storage container such as a cased CD according to the present invention, even a single CD consisting of a simple packaging case can be securely stored, and one magnet cannot be unlocked by hand while holding one magnet. .

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described.
This will be described with reference to the drawings. FIG. 1 shows a single C of the present invention.
FIG. 2 is an enlarged sectional view showing a lock mechanism used for the storage container such as the single CD, and FIG. 3 is used for the storage container such as the single CD. FIG. 4 is a bottom view showing the lock mechanism, and FIG.

As shown in FIG. 1, a storage container 10 such as a case-containing CD includes, for example, a storage container main body 13 having an opening 12 on a side surface through which a CD case 11 storing a single CD can be taken in and out; CD on top of container body 13
A lock mechanism 14 for restricting removal of the case 11 is provided. The storage container body 13 is made of a synthetic resin, and has appropriate rigidity and elasticity. Further, an opening window 15 is formed near the lower part on the front side of the storage container body 13 to such an extent that the CD case 11 does not come out. Further, an opening window 15 is also formed on the rear surface of the storage container main body 13 near the upper portion, with the position shifted from the opening on the front side.

Since the storage container body 13 is made of a transparent or translucent member, the stored CD case 11
Can be visually recognized from the outside. In addition, the jacket or the like can be checked directly from the opening window 15, and even if it is displayed at a store, it does not hinder consumers from checking the contents of the single CD. Further, locking projections 16a for pressing the corners of the CD case are formed in the opening windows 15 on the front and back surfaces, and the opening windows 1 are formed.
5 are formed with semicircular locking projections 16b at appropriate portions.

The opening 12 formed on the side surface of the storage container body 13 has an elongated rectangular shape. Therefore, the vertically long single-size CD case 11 can be taken out and put in the side direction as it is in a state parallel to the storage container body 13.

The lock mechanism 14 is attached to the opening 12 at the upper end of the storage container main body 13. As shown in FIGS. 2 to 5, a leaf spring 17 and a state where the leaf spring 17 protrudes into the opening. And a retaining member 18 to be held. The leaf spring 17 is bent in a U-shape in this embodiment, and elastically sandwiches both sides of the locking member 18. A U-shaped groove 23 is formed on the lower surface of the lock mechanism main body, and the bent end of the leaf spring 17 is fitted into the U-shaped groove 23. Further, the locking member 18
Are formed with engaging step portions 18a and 18b, and when the locking member 18 is pushed in, the leaf spring 17 is engaged between the engaging step portions 18a and 18b on both sides to maintain the pushed state. . The locking member 18 is provided so as to be able to protrude from the upper end of the lock mechanism 14, and the operator performs a locking operation by pressing the top 18c with a finger.

The locking member 18 has V-shaped guide projections 19 on both sides on which the leaf spring 17 does not contact, and a hole 20 in which the locking member 18 protrudes and retracts corresponding to the guide projection 19.
, A V-shaped guide groove 21 is formed. Therefore, since the locking member 18 protrudes and retracts along the V-shaped guide groove 21, as shown in FIG. 6, rattling of the locking member 18 is reduced and operability is improved. Further, the leaf spring 17 engaged between the engaging step portions 18a and 18b attracts the leaf spring 17 by strong magnets from both sides outside the lock mechanism 14 and spreads both sides to engage with the locking member 18. Cancel.
When the engagement is released, the leaf spring 17 can ride on the engagement step 18 a of the locking member 18, and the lower end of the locking member 18 can be retracted from the opening 12.

Next, a description will be given of a method of using the storage container 10 such as a case-containing CD constructed as described above. First, when storing in the storage container 10, the CD case 11
Is stored by sliding from the opening 12 of the storage container body 13 which is not locked. When locking, the top 18c of the locking member 18 protruding upward from the locking mechanism 14 is pushed with a finger, and the locking member 18 is pressed.
Is projected into the opening 12 so that the CD case 11 cannot be removed.

The locking of the lock mechanism 14 is performed by pushing the top 18c projecting upward from the top of the lock mechanism with a finger. When the locking member 18 is pushed in, the leaf springs 17 disposed on both sides of the locking member 18 are engaged with the engaging step portions 18a on both sides, and the locking member 18 is lowered (locked state). State).

In this manner, the lower end of the locking member 18 projects into the opening 12 and is locked. Since the locking member 18 is locked on both sides by the leaf spring 17, there is no possibility that the lock is released (see FIG. 4).

When unlocking, as shown in FIG. 6, an unlocking tool 22 provided with strong magnets located on both sides of the lock mechanism 14 is brought into contact with the lock mechanism 14, and The spring 17 is sucked in the direction of arrow B and opened. Unlocker 22
Has a concave portion 22a in which the lock mechanism 14 can be stored as it is, and has strong magnets (indicated by N poles) on both sides of the concave portion 22a. When the two ends of the leaf spring 17 are sucked and opened, the engagement with the engaging step portion 18a is released, and the locking member 18 can freely move up and down. To rise. That is, the recess 22 a of the unlocking device 22 is turned upward,
When the lock mechanism 14 is fitted in the concave portion 22a by turning it upside down, the leaf spring 17 is opened and the locking member 18 becomes free, and falls by its own weight (same as rising because of the upside down). By raising the locking member 18 in this manner, the stored CD case 11 can be freely moved, so that the CD case 11 can be slid out of the opening 12 and taken out arbitrarily.

Incidentally, if the unlocking device 22 is not used and the magnet is illegally approached to the lock mechanism 14 for unlocking, for example, the position and the unlocking direction of the leaf spring 17 cannot be seen from the outside. Tablets are difficult. Also, it is difficult to hold two strong magnets in close proximity, and unauthorized unlocking is almost impossible.

In the above embodiment, the description has been given of the case where the leaf spring 17 is formed by bending the leaf spring 17 into a U shape. However, the present invention is not limited to this. You may comprise so that both sides may be pinched. It should be noted that the present invention is not limited to the above embodiments, and various modifications can be made based on the technical idea of the present invention.

[0021]

As described above, the storage container such as a case-containing CD according to the present invention is slid to one side end to be C-shaped.
A storage container main body having an opening through which the D case can be inserted and removed, and a lock mechanism attached to the storage container main body and acting on a part of the opening to regulate the insertion and removal of the CD case; Has a structure in which a locking member that can be protruded and retracted into the opening side and a plate spring disposed on both sides of an opposing surface for holding the protruding state of the locking member are provided. Even if a single CD case is weak, it can be securely and safely stored, and even if an unauthorized user tries to unlock the magnet by pulling the leaf spring with a magnet, suction in one direction is easy, but both directions are easy. That is, it is difficult to work against the lock mechanism while holding two strong magnets at a small interval, it is extremely difficult to actually unlock, and the safety is improved accordingly. So single An excellent effect of being able to prevent the illegal carrier such as D.

Further, since the lock mechanism has a V-shaped cross section formed on both side surfaces of the locking member which moves up and down, a V-shaped cross section formed on the guide protrusion of the locking member and the locking mechanism body. There is also an excellent effect that the guide grooves mesh with each other so that there is no backlash and the workability of locking and unlocking is improved.

Further, when the leaf spring is formed by bending a single spring material into a U-shape, the leaf spring that engages on both sides of the locking member can be formed by one component, and the manufacturing cost is reduced. Can be reduced. In addition, the locking member can be sandwiched from both sides only by being housed in the U-shaped groove without firmly fixing the leaf spring to the lock mechanism main body, and an excellent effect that the locking strength can be increased can be achieved.
