Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to an improvement in a storage case that removably stores storage items such as U-Match video tape cassettes.

[Conventional technology]

Generally, this type of storage case includes a case body having a frame-shaped rising peripheral wall, and a skirt wall that is connected to the case body via a back plate so as to be freely openable and closable, and that is removably fitted onto the rising peripheral wall. It consists of a lid body provided with a section. Stored items such as video tape cassettes are fitted into the case body, and the lid is closed for storage and portability. In such a storage case, if the stored items are fitted and stored in the simple frame-shaped upright peripheral wall of the case body, the stored items inside the case body may move unsteadily within the case body, especially when being carried. There were problems in that the stored articles were not held stably, and the movement of the stored articles within the case body caused a strength defect in the frame-shaped rising peripheral wall. Conventionally, in order to solve this problem, a fitting recess is formed on the rising peripheral wall of the case body, and a fitting protrusion is partially bent inward on the skirt wall of the lid. A storage case with a locking protrusion on one of the fitting recess and the fitting protrusion and a locking hole on the other (Utility Model Publication No. 57-58620, Utility Model No. 58620,
No. 56-82770, etc.) are provided. In the case of this storage case, the rising peripheral wall of the case body and the skirt wall of the lid have to be partially bent, which makes the molded shape complicated and increases the mold cost. There were problems in that the appearance of the product was impaired and strength defects were likely to occur in the uneven parts. Furthermore, since the corner portions of the case body were not reinforced, there was a risk of damage when external impact was applied.

[Problem that the invention attempts to solve]

This idea was made in view of the above circumstances,
The corners of the case body are reinforced with a double structure using corner members, and when the lid is closed, a fitting member is fitted between opposing corner members, and the fitting members and corner members abut against each other, so that the corner members are lined up. It is an object of the present invention to provide a storage case which has excellent stability and strength by regulating the movement in the direction, and further regulating the movement in the direction orthogonal to the above direction by engagement between the notch engagement part and the rising peripheral wall part.

[Means to solve the problem]

In order to solve this problem, this invention includes (a) a case body having a frame-shaped rising peripheral wall along the peripheral edge of the bottom plate, and a frame-shaped skirt wall that is removably fitted to the outside of the rising peripheral wall; (b) at each inner corner of a rising peripheral wall surrounding the case body in a rectangular shape; Four corner members are provided, each of which has a projecting piece whose both ends extend inward from the adjacent peripheral wall at right angles to each other, and a connecting part which connects the projecting pieces and extends along the inner corner part, (c ) A pair of protruding wall parts provided on the inner surface of each circumferential wall of the skirt wall part of the lid body and extending inward from the same circumferential wall at right angles, and a pair of protruding wall parts extending substantially parallel to the skirt wall part at the tip of the protruding wall part. (d) a projecting wall of the fitting member; and a fitting member that is fitted between the adjacent corner members and abuts the opposing projecting piece of the corner member when the lid is closed. A technical measure has been taken in which a groove-shaped notch engaging portion is provided in the corner member and is fitted from above and engaged with the rising peripheral wall portion between the corner members when the lid is closed.

[Effect]

The corner parts of the case body have a double structure with corner members, so the box shape can be reinforced. Further, when the lid is closed, the fitting member is fitted between the opposing corner members, and the protruding wall portion of the fitting member and the protruding piece portion of the corner member abut each other to ensure accurate positioning. Furthermore, since the rising peripheral wall part is fitted into and engaged with the groove of the notch engagement part formed in the projecting wall part of the fitting member from above, the alignment position is restrained and movement in the vertical and lateral directions can be restricted. can. As a result, when the lid is closed, the case body and the lid body are restrained vertically and horizontally, so there is no risk of them shifting, and the corner portions are reinforced against external impacts, resulting in excellent strength.
