Description

  The present invention relates to a paper storage case.

It is well known that storage cases made of paperboard or cardboard, such as CDs (compact discs) and magneto-optical discs, are widely used because of their remarkable weight reduction and cost reduction effects. The conventional case made of paperboard does not have any special problems for display, sale, and normal storage, but it is not strong and may be damaged by long-term storage or mailing, etc. There was a problem that could not withstand the use of.

The applicant has disclosed a case technique that is strong and easy to manufacture. (See Patent Document 1).
In addition, a technique for reducing the material used without disposing the wrong placement position when storing a CD is disclosed (see Patent Document 2).

In recent years, in addition to storage of a recording medium, it has been desired that a case of a recording medium also store various materials related to information stored in the recording medium and various related products (so-called “goods”).
However, if such materials and goods can be accommodated, it will be difficult to secure strength and the difficulty of manufacturing will increase. For this reason, a paper storage case capable of meeting the above-described demand for storing various materials and goods on a recording medium is not provided at present.
Japanese Unexamined Patent Publication No. 2000-226090 JP 2001-253488 A

The present invention has been proposed in view of the above-described problems of the prior art, and can store various materials and goods in addition to storage items such as recording media, and also ensure a predetermined strength in the case itself. The purpose is to provide a paper storage case that can be worn out.

The paper storage case of the present invention has an outer case (2) and an inner case (7) slidably disposed inside the outer case (2). The outer case (2) and the inner case (7) is formed by bending patterns (7B, 2B) each having a specific planar shape, and includes a first storage portion (V1) for storing storage items (M), and the first storage. The second storage portion (V2) formed separately from the portion (V1) has a pair of hollow portions extending in the sliding direction of the inner case (7). And a paper storage case in which one surface of the square columnar member (65, 65) is joined to the planar portion of the inner case (7). The pair of hollow quadrangular columnar members (65, 65) are cut in a direction perpendicular to the sliding direction of the inner case ( 2h) is characterized in that is formed (claim 1).

In carrying out the present invention, it is preferable that the separately formed second storage portion is made as large as possible and the thickness dimension thereof is increased so that compressive deformation due to a decrease in compressive strength does not occur.

In the present invention having such a configuration, the bending and compressive strength of the inner case and the entire case are increased by joining one surface of the square columnar member to the planar portion of the inner case (7). Damage to the stored items can be prevented.

Here, as a result of warping of the inner case is eliminated, as never hinder the extraction of the recording medium other stored articles, you consideration to reduce the flexural rigidity. Therefore, in the present invention, the one pair of hollow quadrangular prism member (65, 65) is that have the direction of the cut perpendicular to the sliding direction of the inner case (7) (62h) is formed. By adopting such a configuration, the bending rigidity of the inner case (7) can be lowered. Specifically, a cut is formed at a position where the bending rigidity is lowered only when the inner case (7) is pulled out.

The effects of the present invention are listed below.
(A) Since a second storage unit that is separate from the first storage unit that stores storage items such as recording media is provided, materials and goods can be stored.
(B) Since the second storage portion is provided by the inner case in which the hollow square columnar members extending in the sliding direction are joined, the compression buckling strength can be increased. As a result, it is possible to prevent damage to stored items such as cases, recording media, and accessories.
(C) Since the case is prevented from being damaged, it can be used as a storage case even after opening.
(D) If a pair of hollow square columnar members (65, 65) are formed with a cut in a direction perpendicular to the sliding direction of the inner case (7), when the inner case is pulled out, the cut will bring it to the back side. It can be configured to easily warp.
Therefore, it is possible to easily take out the stored items.
(E) The structure is simple, the manufacture is easy, and the amount of paper used is small.
