ABSTRACT:
The present invention relates to a sleeve for storing a disc shaped object, said sleeve comprising a first and second sleeve part which are hingedly connected to each other by means of a hinge member.
Such sleeves are well known for storing a CD audio, a CD-ROM, or a CD-
1
. Generally they are made of hard plastic boxes, having a carrying part and a cover part, which form both sleeve parts. The cover part hinges with respect to the carrying part in order to open or close the sleeve.
A drawback of the known sleeves is that they are inconvenient for mass storage and frequent use. For the storage of a plurality of discs, dedicated racks, having appropriate slots for each sleeve, are required. Moreover, retrieving the disc shaped object from the sleeve also requires a lot of movements.
An object of the invention is to provide a sleeve for storing a disc shaped object, which is easier to handle and more suitable for mass storage.
A sleeve according to the invention is therefore characterised in that the sleeve parts comprise two flaps, folded towards each other along a fold line, said first and second sleeve part comprising a first and second circle segment shaped sliding groove, respectively located in such a manner that in a closed position of said sleeve, they extend along a quarter of a circle, said hinge member being located at a corner of said sleeve forming a middle point for said quarter of a circle, said sleeve further comprises a first and second connecting member located in said first, respectively said second groove and connecting the sleeve parts to each other. The use of two sleeve parts which are connected to each other by means of the first and second connecting member and the hinge member, enables to open and close the sleeve by means of a pivotal movement of both sleeve parts with respect to each other. Since the first and second connecting member are located in their respective grooves, they move in their grooves upon opening and closing of the sleeve. That movement causes the connecting members to apply a force on the object upon opening the sleeve, in such a manner that the object is pushed out of the sleeve. Upon closing the sleeve, the fold line will on its turn push the object inside the sleeve. An easier handling is thus obtained when the object has to be removed from the sleeve or put into it. Since the hinge member is located at a corner, forming a middle point of the quarter of a circle, several sleeves can be connected together by means of their hinge member, thus providing suitable mass storage.
A first preferred embodiment of a sleeve according to the invention is characterised in that said sliding grooves each time extend through both of said flaps. This facilitates manufacturing as it enables to have the first and second sleeve part equally shaped.
Preferably, said hinge member and said first and second connecting member, are situated at the corner points of a rectangular triangle when said sleeve is in a closed position. The storage capacity of the sleeve is in such a manner not adversely affected by the presence of the connecting members.
A second preferred embodiment of a sleeve according to the invention is characterised in that each sleeve part comprises a set of attachment holes situated along a side of the sleeve at a calibrated distance of each other. The sleeve can thus be stored in an index file.
A third preferred embodiment of a sleeve according to the invention is characterised in that each sleeve part comprises a prehension member situated at a diagonally opposite corner of the one where said hinge member is located. The prehension member facilitates the opening of the sleeve.
