Package for disc-like recording medium

Abstract

The present invention relates to a package for disc-like recording medium having a storage body made of a sheet of paper material and which is composed of a plurality of members formed by respectively folding a plurality of broken lines and in which a disc-like recording medium can be stored such that the disc-like recording medium can be freely inserted into and ejected from the package for disc-like recording medium. In a conventional envelope with CD label window, an envelope main body and a film are made of different paper materials and problems arise, in which two kinds of paper materials should be prepared. A package for disc-like recording medium according to the present invention has a storage body formed from a sheet of a paper material by a cutting-process and which is composed of a plurality of members formed by folding a plurality of broken lines, wherein a window portion is formed on one member to expose a CD indication plane and wherein a CD can be stored therein such that it can be freely inserted into and ejected from the package for disc-like recording medium. A plurality of members has a CD back member (11) opposing the back of the CD, a CD holder member (12) overlaid over the CD back member by folding a broken line to hold a CD thereon, a window portion (17) to expose the indication plane of the CD held on the CD holder member and a recess insertion slot (20) for a CD. A frame body member (13) overlaid over the CD holder member by folding a broken line and a CD upper surface member (14) overlaid over the frame body member by folding a broken line so as to cover the CD indication plane exposed to the window portion of this frame body member are unitarily formed as one body. According to the present invention, a suitable medium such as a CD can be freely stored in this package for disc-like recording medium in such a manner that it can be freely inserted into and ejected from this package for disc-like recording medium. Also, it is possible for a user to reliably read indicated contents on the indication plane of the disc-like recording medium such as the CD through this window portion.

Description

TECHICAL FIELD [0001] The present invention relates to a package for disc-like recording medium in which a disc-like recording medium such as a CD (Compact Disc) and a DVD (Digital Versatile Disc) can be stored so as to be inserted into and ejected freely, and particularly to a package for disc-like recording medium having a storage body made of a sheet of a recyclable paper and which is composed of a plurality of members formed by folding a plurality of broken lines. BACKGROUND ART [0002] As a CD package body, an envelope with CD label window has hitherto been known, in which a window portion is formed on the front surface side of the envelope into which a CD is inserted such that a user becomes able to see an indication plane of the CD (see Cited Patent Reference 1, for example). [0003] In this envelope with CD label window, an envelope main body is made of a recyclable paper material and a window portion through which a user can see the indication plane of the CD is formed as a c...

AI Technical Summary

Benefits of technology

[0010] According to the above-mentioned package for disc-like recording medium, since the storage body is composed of a plurality of members by cutting a sheet of paper material and by folding a plurality of broken lines and the substantially circular window portion is formed on one member to expose the indication plane of the disc-like recording medium, the disc-like recording medium can be stored in the package for disc-like recording medium such that it can be freely inserted into and ejected from the package for disc-like recording medium and substantially the whole of the surface of the disc-like recording medium is not hidden so that a user can reliably read the indicated contents through the window portion.

[0011] Also, since the window portion is not covered with the film and opened and it is constructed by a sheet of cut-out paper material as a package body of a disc-like recording medium, manufacturing processes can be decreased and a manufacturing cost also can be decreased.

[0012] Further, since the fastening margins formed at both sides of the frame body member are attached to the back of the recording medium back member to form the disc-like recording medium insertion slot after the frame body member was folded and overlaid over the recording medium holder member, when the disc-like recording medium is inserted from this recording medium insertion slot, the disc-like recording medium can be inserted into and ejected from the package for disc-like recording medium without damaging the recording surface of the disc-like recording medium and the disc-like recording medium can be held on the recording medium holder member having no difference in level formed thereon. Furthermore, when the disc-like recording medium is inserted into the recording medium storage portion, since the indication plane of the disc-like recording medium is directly exposed to the window portion, it is possible for a user to easily read the whole of indicated contents printed on the indication plane.

[0018] According to the package for disc-like recording medium, since the recording medium holder member is folded and overlaid over the recording medium back member, the difference in level can be prevented from being produced and the disc-like recording medium can be inserted into and ejected from the package for disc-like recording medium from the disc-like recording medium recess insertion slot formed by folding the frame body member while the disc-like recording medium is being in contact with the surface of the recording medium holder member. Therefore, the disc-like recording medium can be stored in the recording medium storage portion without damaging the recording surface of the disc-like recording medium.

Problems solved by technology

However, in the case of the former envelope with CD label window (Cited Patent Reference 1), the envelope main body and the film should be made of different paper materials and therefore two kinds of paper materials should be prepared, which is cumbersome.

Furthermore, since the film should be attached to the envelope main body, a problem arises, in which the attachment portion should be formed as a double structure.

Then, a problem arises, in which a user becomes unable to look at the CD indication plane.

Further, one member of the pasteboard with the semi-circular arc-like recess formed thereon has encountered with the following problem.

As a consequence, when the CD is inserted into and ejected from the CD package body through this semi-circular arc-like recess, there is a risk in which a recording surface of the CD will be rubbed by the corner edge of the difference in level, resulting in the recording surface being damaged.
