Description

TITLE OF THE INVENTION Holder BACKGROUND OF THE INVENTION The present invention relates to a holder which is applicable to a primary container for articles and which is capable of releasably holding such an article and particularly to a suitable holder which is applicable as a primary container of the musical compact disk or the CD ROM.

In general, the musical compact disk is put on sale while being contained in a flat case of hard plastic resin material. Said musical compact disk comprises a pair of substantially rectangular boards relatively hinged such that each of said boards swing to the other. One of the two plates are inwardly and centrally formed with a boss which is adapted to be engaged with the center hole formed in the musical compact disk, whereby the musical disk is held by engaging said boss into the center hole of the musical compact disk. For opening and closing operation, while small protuberances projecting from outer sides of one of the plates are engaged in recesses or holes formed in inner side surfaces of the other plate to maintain the closed state, said small protuberances are disengaged from said recesses or holes to open the case plate.

However, since the aforementioned conventional musical compact disk is relatively thick in size and expensive in cost, the low cost and small size case which effectively hold a musical compact disk has been hoped for. The aforementioned is also in demand as a compact disk case for electronic publication or supplemented CD-ROMs of periodicals.

SUMMARY OF THE INVENTION The object of the present invention is to provide a holder which overcomes the problems in the art by holding an article securely and which is manufactured at low cost and applicable to a small case so that said holder releasably holds the article.

In order to accomplish the aforementioned problem, the holder of the present invention is characterized by comprising a self-tacky film of resin material laid over the surface of a base plate to releasably hold an article, said film being composed to have an adhesiveness such that no resin material is transplanted to the article being peeled off.

The holder is further characterized in that said selftacky film is made of an easily electrified material.

The holder is further characterized in that said selftackey film is printed on the surface of said base films.

The holder is further characterized in that said selftackey film is paisted on the surface of said base film.

Further, the holder of aforementioned construction makes it possible to hold an article securely by causing the self-tacky film to stick to the article. Since the film is capable of holding the article detachably and repeatedly by virtue of its self-tackiness, the film is best suited for the holder of the compact disk. In case of holding the compact disk particularly, the dust on the surface of the compact disk is adsorbed to the self-tacky film to clean the surface.

If the self-tacky film is made of an easily eletcrified material, the charged film attains the power to hold the article even more securely.

BRIEF EXPLANATION OF THE DRAWINGS Fig.l is a developed plan view of the case showing the embodiment of the present invention; Fig.2 is a bottom view of Fig. 1; and Fig. 3 a perspective view of the state in which the the case containing the article is being closed.

DESCRIPTION OF THE PREFERRED EMBODIMENT The embodiment of the present invention will be explained with reference to the drawings as follows.

Fig.l through Fig. 3 show a case 1 for the musical compact disk employing the holder according to the present invention. The case 1 is composed of two elongated boards 2A and 2B bonded to each other such that said two boards form base plates. Said case 1 includes three wall sections 4A, 4B and 4C of substantially similar shape arranged in the same directions by way of two folds 3A and 3B which are arranged parallelly to each other. By bending the fold 3A, the wall section 4A is folded over the wall section 4B.

Then, the fold 3B is bent to fold the wall section 4C over the wall section 4A to forming the encased state. Said folds 3A and 3B are formed only of the board 2A, in which the fold 3B which is bent later is sized broader than the fold 3A which is bent first such that the bending is done easily.

The inside surface 5A of said wall section 4A is formed with a substantially circular recess of an inside diameter having a size substantially equal to the outside diameter of the musical compact disk (not shown) by cutting out the board sheet 2A. Further, the outer periphery of said recess 7 is continuously formed with four substantially semicircular cutouts 8 at 90 degree angular spacings for inserting a finger thereinto when taking out the musical compact disk.

A circular self-tacky film 9A is laid over substantially the whole of the back of said board 2B in the recess 7. Here, "laid over" means the state of being fixed on the board by printing or pasting.

Said self-tacky film 9A is made of resin material such as polyvinyl chloride or PET (polyethylene terephthalate) such that said film sticks to articles by virtue of selftackiness of these resin materials to releasably hold said article. Said self-tacky film 9A used in the present invention is set to have a weak adhesiveness ( e.g. about 3 to 20 g/25mm) such that no resin material adheres to and is transplanted to an article like the musical compact disk.

Moreover, said tackiness is reproductive.

Further, if said self-tacky film 9A is formed of an easily electrified material such as polyvinyl chloride, it is possible to hold the article even more securely because the charged film 9A attracts the article.

While said self-tacky film 9A is laid over substantially the whole area within said recess 7 in this embodiment, it is also possible to lay it only centrally or partially.

On the other hand, rectangular self-tacky films 9B and 9C are laid, by printing or pasting for mutual adhesion, over the respective one ends of the outside face 6A of the wall section 4A and the inside face 5C of the wall section 4C as shown in Fig. 3 such that the wall sections 4A and 4C are opened and closed. Said self-tacky films 9B and 9C are made of similar material as the aforementioned film 9A. If the surface of the boards 2A and 2B are smooth enough, only one of the mating self-tacky films 9B or 9C may be provided for adhesion to board 2A or 2B.

Next, the embodiment of the invention having the aforesaid construction.

In order to contain and hold a musical compact disk, the case 1 is opened to engage the musical compack disk within the recess 7 in the wall section 4A. Since the selftacky film 9A is laid over the floor surface of the recess 7, the musical compact disk sticks to the surface of the film 9A by virtue of the self-tackiness thereof to be held there. In case where the self-tacky film 9A is of a material easily electrified, the charged film 9A sticks to the musical compact disk to securely hold the same therewithin.

Then, the fold 3A is bent as shown in Fig.3 to fold the wall section 4A over the wall section 4B before said fold 3B is bent to fold the wall section 4C over the wall section 4A such that the self-tacky film 9C on the wall section 4C sticks to the self-tacky film 9B on the wall section 4A to complete the encased state.

In order to take out the musical compact disk from the case 1, both self tacky films 9B and 9C are separated into an open state as shown in Fig. 3 and further in Fig.l such that the musical compact disk sticking to the self-tacky film 9A is manually picked out from the recess 7. Since the adhesive force of the self-tacky film 9A is weak while no resin material is transplanted to the musical disk, the musical compact disk is easily taken out without damaging the sound quality. Moreover, the dust which has been sticking to the musical compact disk is left behind on the self-tacky film 9A with the result that the surface of the musical compact disk is cleaned.

In this way, the case 1 in this embodiment makes it possible to securely hold the musical compact disk in repeated uses.

Further, since lamination of the self-tacky film 9A may be possible by printing, the structure is so simple that cost reduction and miniturization are possible.

The openable structure of the case by use of the selftacky film 9B and 9C is also so simple that the cost reduction in this respect is possible.

The present invention shall not be restricted to the aforementioned embodiment and many modifications are allowable to meet various needs. In other words, the article to be held therewithin is not limited to the musical compact disk.

As explained in the foregoing, the holder according to the present invention makes it possible to securely and removably hold an article therewithin while low cost production and miniturization are possible.
