Description

  The present invention relates to a storage box for storing stored items.

  A paper-made storage box is used as a container for storing things such as gifts. A general paper storage box is composed of a container-like box main body capable of storing items, and a lid which covers the outer periphery of the box main body while closing the upper opening of the box main body. Such a storage box is required to reduce the amount of paper used from the recent increase in eco-friendliness. For this reason, a storage box has been developed in which the height of the box body of the storage box is smaller than that of the lid. For example, in the cited reference 1, a locking step continuous with the side wall is provided at the upper part of the ridge line between the adjacent side walls of the lid, and the locking step is folded inwardly to form the other side wall adjacent to the glue margin By sticking to the above, a structure is disclosed in which the locking step projects inward from the ridge line of the adjacent side wall. When the lid of this structure is placed on the box body, the locking step abuts on the upper end of the peripheral wall of the box body and is locked. In this way, the height of the peripheral wall of the box body can be lowered, so the amount of base paper used to manufacture the storage box can be reduced.

  However, in the case of the lid having the above structure, the locking step can not be enlarged because the locking step protrudes inward from the inner surface of the lid. The reason is that if the locking step is enlarged and the amount of protrusion is increased, the tip of the locking step may contact the stored item stored in the storage box, and the stored item may be deformed or damaged. . For this reason, this lid is restricted by the size and shape of the locking step, and in particular, the amount of protrusion of the locking step can not be designed large. Not only is it difficult to reliably abut on the upper end of the peripheral wall of the box body to support the locking step having a small amount of projection, but the strength is also weakened. Therefore, when a large load is applied to the lid and this load is concentrated on the engagement portion between the engagement step and the upper end of the box body, the engagement between the engagement step and the upper end of the box body is released or engaged. The stop may be crushed. In this state, the upper wall of the lid is pushed down by load and abuts on the contents, causing a problem that the contents are deformed or broken.

  The present invention has been made to solve the above problems. One of the objects of the present invention is to make the height of the box body lower than the height of the lid to reduce the amount of base paper used for producing the storage box, and to apply a load to the lid even when the lid is loaded. An object of the present invention is to provide a storage box capable of protecting a storage item by preventing a wall from coming into contact with the storage item.
