Abstract

PURPOSE: To provide a packaging device being suitable for the packaging of disk-shaped articles, wherein the taking out or putting in of an article to be packaged or the attaching or removing of a verse card or explanation slip can be easily done, and a stable packaging can be performed so that an abrasion may not generate inside. CONSTITUTION: A leaf paper is folded into a flat form of a polygonal shape which is flat and triangular or more, and a paper package 2 is constituted by exposing one part of the folded line 6 at least to one surface of the flat surface, and the package 2 is inserted between a folded face paper 1. By doing so, the opening/closing is easy, and a disk-form article can be contained while being prevented from freely moving. In addition, the disk-form article can be well kept from dropping, and by making the whole body with paper, the package can be manufactured at a low cost, and the disposal is facilitated as well.

過傷が入る恐れがあって好ましくない。Since it is difficult to print lyrics and explanations on a plastic case, when using the case for packaging, a separately prepared lyrics card or instruction manual should be used in the case. It is necessary to enclose it in, and the enclosing work is a manual work, so it has the disadvantage of poor workability.If a returned product occurs, it is necessary to remove the lyrics card etc. to reuse the case, and this work is also enclosed As troublesome as work. Also, when wrapped in a bag, it is easy to enclose lyrics cards, etc., but the size of the bag must be slightly larger than a disk-shaped object such as a compact disc, so vibration during transportation It is not preferable because there is a risk of scratches when inserting or removing the disc.

棄作業も簡単になる。When the paper wrapping body is accompanied by a folding cover, the folding cover is opened, and the side face of the packaging body is opened when the folded folding end of the paper wrapping body interposed therebetween is lifted. A disc-shaped object such as a compact disc is accommodated in the inside thereof, and when the folded end is pressed, the packaging body is closed and the disc-shaped object can be accommodated. Since the package is polygonal,
The disk-shaped object can be accommodated by inscribing the peripheral edge of the polygonal side, the disk-shaped object does not move inside the package, and can prevent abrasion due to transportation, etc. The disc-like material can be sufficiently held in the package due to the elasticity of the folded piece having a relatively large area and the resilience of the relatively large fold between the angular folded pieces. The lyrics and explanations can be printed on the cover, or a pouch can be attached to the inside of the cover to store it. When discarding due to returned goods or the like, the disc-shaped material can be taken out according to the above procedure, and the cover and the packaging body can be discriminated from the disc-shaped material and disposed of by incineration.
