ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a disc casing for containing a compact disc (hereinafter abbreviated as CD) or a memory disc such as a CD-ROM.
2. Related Arts
Referring to
FIG. 16
, a CD casing
1
is made of a synthetic resin material, comprising a case housing
3
having a circular disc container section
2
formed therein and a cover
6
rotatably attached to the case housing
3
by inserting hinge pins
5
in the holes made in the upper and lower ends
4
of the case housing
3
.
The circular disc container section
2
has a cylindrical projection
7
formed at its center. The cylindrical projection
7
is somewhat resilient, permitting a CD to be held by inserting the cylindrical projection
7
in the center circular hole of the CD.
As seen from the drawing, the cover
6
has tongue-like projections
9
formed on its opposite longitudinal walls
8
, thus defining small gaps between the tongue-like projections
9
and the inner surface
6
a
of the cover
6
for removably holding a booklet, which describes the contents of the CD.
Such a CD casing
1
of synthetic resin, however, prevents the title of the CD, ornamental patterns, the words of the recorded song or any other pieces of information from being printed on the CD casing.
The space available for holding a booklet is relatively small, and accordingly, the booklet size is limited. The booklet is prone to be lost because it is a separate object.
It is required that the synthetic material when disposed of, be separated from paper or other combustible waste. Use of such incombustible material is a significant cause for environmental pollution, and therefore, should be refrained to possible extent.
SUMMARY OF THE INVENTION
One object of the present invention is to provide a CD casing which permits the printing thereon, and is capable of containing as much information as required without the fear of losing the same, causing no environmental pollution problem when disposed of by combustion.
To attain this object a book-like disc casing according to the present invention comprises a series of a front cover, a spine and a rear cover, made of cardboard, and a plurality of pieces of paper, the front cover, spine and rear cover being folded to be like a book with the pieces of paper interleaved between the front cover and the rear cover, at least one of the front and rear covers having an intermediate member and a lining member laid on each other to form a lamination inside, the intermediate member having a disc-accommodating space formed therein, and the lining member having a line of perforations and creases intercepting the line of perforations, which is partly in conformity with the contour of the disc accommodating space, thereby facilitating the making of an opening in the lining member to permit the taking-out of the disc from the disc accommodating space.
The part of the lining member defined by the line of perforations when cut open therealong, provides a flap which can be folded to turn about the creases, which have a catch projection integrally connected thereto, permitting the catch projection to catch and raise the disc when the flap is made to turn for opening.
The disc accommodating space is of polygonal form, the inner sides of which are tangential to the circumference of the disc to be contained.
The flap provided by the lining member has a window formed therein to permit confirmation of the disk being contained by sight.
The pieces of paper may bear pieces of information pertaining to the contents of the disc, decorative patterns, and blanks for notes.
Other objects and advantages of the present invention will be understood from the following description of CD casings according to some preferred embodiments of the present invention, which are shown in accompanying drawings.
