【Example】

 An embodiment in which the present invention is applied to a storage case for storing a video tape will be described below with reference to the drawings. The storage case 1 shown in FIGS. 1 and 2 is made of a synthetic resin, and has a continuous rear wall 4 which connects the case body 2 and the lid 3 with the first hinge portion 41 and the second hinge portion 42. It has a flexible structure. That is, the case main body 2 is erected at the same height so as to cover the rectangular bottom wall 21 having one side continuously connected to the first hinge portion 41 and the remaining edge portions on three sides, and the first hinge The front wall 22 is arranged at the opposite edge of the portion 41, and left and right side walls 23, 24 are arranged at the left and right sides.

On the front wall 22, a pair of rod-shaped stoppers 51, 52 are vertically provided integrally vertically from the bottom wall 21 toward the center, and on the outer side thereof, a pair of left and right rod-shaped protrusions are provided. The parts 61 and 61 are vertically erected integrally with the bottom wall 21. Here, since the protrusion 61 extends integrally from the bottom wall 21 to the middle position of the front wall 22, it also functions as a crosspiece for reinforcing the front wall 22. Next, on the left and right side walls 23, 24, a pair of rod-shaped stoppers 53, 54, 56, 57 are vertically provided integrally and vertically from the bottom wall 21 toward the center. Further, on the inner surfaces of the left and right side walls 23, 24 on the front side, locking projections 81, 81 each of which is a laterally long cross-sectional substantially triangular shape and projecting inward are provided.

Next, the front wall 32 of the lid body 3 has a reinforcing U-shaped bent portion 32a that bends inward in a planar U shape at the center. When the storage case is closed, the U-shaped bent portion 32a is recessed inward so that the stoppers 51 and 52 of the front wall 22 are fitted in the recessed direction with substantially no space to form a spacer in the front-rear direction. .

Further, the front wall 32 is formed with a cutout portion 7 which is cut out in a substantially U-shape in a laterally inverted manner except for the left and right sides thereof. The edge portions of the left and right vertical sides forming the cutout portion 7 are inclined slightly inward in the proximal direction to form a pair of left and right abutting side portions 71. The pair of abutting sides 71 are obliquely set so that when the lid 3 is closed to the case body 2, the abutting ends of the pair of protrusions 61 abut against each other from the outside and are in close contact with the protrusions 61. It In this embodiment, one cutout portion is provided and the abutting side portion is provided on the vertical side forming the cutout portion. However, for example, it corresponds to each protrusion 61 and the protrusion 61 can be freely retracted. It is also possible to form a concave portion that forms the concave portion and use the side that forms the concave portion as the abutting side portion.

Reference numerals 33a and 34a denote reinforcing U-shaped bent portions provided on the side walls 33 and 34 of the lid body 3, respectively, and the stoppers 53 and 54 when the storage case is closed. 55 and 56 serve as spacers fitted in the recessed directions of the U-shaped bent portions 33a and 34a with substantially no gap, thereby preventing rattling in the left-right direction. Reference numeral 35 is a rear wall that is connected to the rear ends of the side walls 33 and 34, and has a U-shaped bent portion 35a that projects outward in the center.

With the above configuration, when the lid body 3 is bent and fitted into the case body 2 via the first hinge portion 41 and the second hinge portion 42, the peripheral wall on the lid body 3 side (front wall 32 , The left and right side walls 33, 34, and the rear wall 35) are fitted. At that time, the locking projections 81, 81 provided on the side walls 23, 24 of the case body are projected into the locking recesses 82, 82 provided on the side walls 33, 34 of the lid body, and the side wall 33 of the lid body 3, 34 and the side walls 23 and 24 of the case body 2 are constrained in the direction of opening and closing the case. At the same time, the front wall 32 of the lid 3 is inserted so as to overlap the inside of the front wall 22 of the case body 2.

As a result, the abutting side portion 71 of the front wall 32 of the lid 3 comes into contact with the side of the protrusion 61 of the front wall 22 of the case body 2 from the outside (left side in FIG. 2), and the abutting side portion 72 is formed. The side wall of the protrusion 62 is contacted and fitted from the outside (right side in FIG. 2). At this time, the abutting piece portions 71, 72 are set obliquely so that the side abutting against the tips of the protruding portions 61, 62 is in close contact with the protruding portions 61, 62. The storage case described in 1, 2, or 3.

Therefore, when a load is applied in the opening direction of the lid body 3, the lid body 3 is restrained at the abutting side portions 71 and 72 by the protrusions 61 and 62, so that The top wall 31 and the bottom wall 21 are bent because they prevent the displacement of 72 in the direction of maintaining and narrowing the space and at the same time prevent the displacement of the protrusions 61 and 62 in the direction of expanding. Therefore, the engaging force between the locking projection 81 and the locking recess 82 is not impaired. Therefore, even if a load is applied in the opening direction, the lid 3 of the storage case 1 does not open accidentally. The stoppers 51 to 56 of the case body are fitted in the recessed portions of the U-shaped bent portions 32a to 34a of the lid body to prevent the storage case 1 from deforming.

In this invention, the protrusion is exemplified by a rod-shaped member, but it engages with the abutment side portion and abuts against the abutment side portion so as to be restrained when a lateral load is applied. The shape is not particularly limited as long as it is cylindrical. Further, the restraining side portion may be an edge portion that forms a recess or a cutout having an appropriate shape, and needless to say, is not limited to the configuration formed in the cutout portion as in this embodiment. Further, the locking projection and the locking receiving portion may be configured so as to lock the lid body and the case body in the opening / closing direction. In addition, it goes without saying that various designs can be changed without changing the gist of the present invention.

[0015]

[Effect of device]

 According to the present invention, even if a load is applied in the opening direction of the storage case, the lid body and the storage case do not bend in the left-right direction due to the engagement of the abutting side portion and the projection portion. The engaging portions of the housing case and the engaging projections and the engaging recesses are securely deformed without being deformed. Thereby, the lid of the storage case is not opened carelessly and the lid and the case body are not deformed, so that the reliability can be improved.
