Description

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

This invention relates to a storage case in which a lid body having a housing portion is connected to the case body via a hinge portion so as to be openable and closed, and particularly relates to an improvement in the opening/closing structure of the case body and a lid body having a housing portion.

[Conventional technology]

Conventionally, as a storage case for tape cassettes, etc.
As shown in the cassette storage case of Utility Model Application Publication No. 57-164880, the case body and the lid body with the storage section fixed thereon are formed separately, and both are pivotally connected by pins or bosses and holes. The configuration is known. In this case, the pivoting between the case body and the lid is done by the engagement of pins and holes, so if the storage case is deformed or the pins or holes are damaged, the case body and the lid cannot be pivotally connected. There is. Furthermore, since the case body and the lid body are separate bodies, they must be molded separately, and an attachment process for pivotally connecting them is also required. Therefore, the connection between the case body and the lid body was changed to the above-mentioned pin-and-hole pivot structure, and a hinge structure made of a V-groove shape that utilized the elasticity of synthetic resin was used. Cases for cassettes are known. In this configuration, the case body and the lid are integrally molded via the hinge portion, so the above-mentioned drawbacks can be solved, but there is a problem in that the folded storage portion cannot be integrally formed on the lid. Furthermore, in the former case, the lid housing the tape cassette is rotated 270 degrees to abut against the edge of the notch, and the lid can be used by standing up in the inverted state. In this case, since the lid is inverted, there is a risk that the tape cassette stored in the lid may fall when the lid is inverted, and the user is required to rotate the lid while holding the tape cassette with his or her hand, which is cumbersome. Furthermore, when a hinge is used as in the latter case, it is completely impossible to use the lid body in an upright position.

[Problem that the invention attempts to solve]

This idea was devised as a result of intensive research in view of the above circumstances, and its main challenges were to connect the lid body and the case body via a hinge part, and to expand the lid body into an upright shape without inverting it. We provide a storage case that can be used.

[Means to solve the problem]

In order to achieve the above-mentioned problems, this invention provides a storage case in which a lid body having a housing part in a case body is connected to the case body in a flexible manner via a hinge part to open and close: (a) the lid body is connected to a plate-shaped top part; , a lateral piece bent toward the case body on both left and right sides of the top surface, a back surface connected orthogonally along the base end of the top surface, and a back surface of the back surface on the case body side. It consists of a holding piece that is continuously bent only at the middle position of the edge and extends parallel to the top surface, (b) an edge on the case body side of the back part where the holding piece is not provided; (c) The case body is connected to the case body through a hinge portion formed on an extension line of the bent portion of the pusher piece and which is a V-groove that serves as a pivot point for opening and closing the lid body; , a plate-shaped bottom part with a notch that is set in a shape corresponding to the outer circumferential shape of the holding piece and is fitted without a gap so that the case is on the same surface when folded; and at least the lid side at both left and right ends of the bottom part. (d) a lid opening engagement means protruding from the outside of the lateral piece of the lid and engaging with the rear end of the peripheral wall of the case body; , took technical measures.

[Effect]

As a result, when the lid is closed, the storage part forming piece is fitted into the case body and becomes a part of the bottom part, and when the lid is opened, it is displaced in conjunction with the lid using the hinge as a pivot point, and is attached to the storage part. The fitted stored items are rotated and displaced in an upright manner. By rotating the lid approximately 90 degrees with respect to the case body while storing the item, the bottom part of the lid that is continuous with the back of the case body is tilted forward slightly, and the lateral side of the lid The lid opening engagement means protruding from the outside of the case body is held in an upright state in engagement with the rear end of the peripheral wall of the case body.

【Example】

A preferred embodiment of this invention will be described below with reference to the drawings. The storage case 1 shown in FIGS. 1 and 4 is made of a synthetic resin material such as polypropylene, and has a structure in which a lid body 3 having a storage section 4 and a case body 2 are connected via a hinge section 5. . That is, the lid body 3 includes a top surface portion 30, a back surface portion 42 that is orthogonally connected on the side where the case body 2 is connected to the top surface portion 30, and a back surface portion 42 that connects the top surface portion 30 at approximately the center of the back surface portion 42.
and a holding piece part 41 which is an example of a storage part forming piece which is folded back and connected in a parallel spaced manner. In addition, a pair of left and right side pieces 43 are provided at both end sides of the lid body 3 along the middle part of the back surface portion 42 and the top surface portion 30.
are connected. Therefore, the space surrounded by the top surface portion 30, the back surface portion 42, the pressing piece portion 41, and the side piece portion 43 constitutes the storage portion 4. Next, the case body 2 has a bottom part 20 and a bottom part 2.
0 is formed on the connection side of the lid body 3 of the storage case 1.
It consists of a notch 22 into which the holding piece 41 is fitted flush and without any gaps, and a peripheral wall 21 protruding from three side edges of the bottom 20 excluding the side where the lid 3 is connected. In the case of the illustrated example, the lid 3 and the case body 2 are located at the base (bent Hinge parts 5 are formed on both sides except for the part). For this hinge portion 5, a groove having a V-shaped cross section is used. The storage case 1 also includes lid locking engagement means 6a and 6b that lock the lid 3 in the closed state when the lid 3 is closed on the case body 2, and locking means 6a and 6b for locking the lid 3 when the lid 3 is opened. It is preferable to provide a lid opening engaging means 7 for holding the lid 3 in an open state so that the stored items can be easily taken out. In the illustrated example, the lid fixing engagement means 6a, 6
b consists of a combination of a pair of protrusions and a recess formed on the side piece 43 of the lid 3 and the left and right sides of the peripheral wall 21 of the case body 2, and the alignment of the protrusion and the recess is The lid 3 is locked in the closed position. Next, the lid opening engagement means 7 is connected to the side piece 4 of the lid body 3.
When the lid body 3 is tilted forward when the lid body 3 is opened, the said protrusion abuts against the rear end of the peripheral wall 21 of the case body 2, and prevents further forward tilting. Thus, the predetermined posture of the lid body 3 is maintained. In addition, in this invention, the pivot point for opening and closing the lid body 3 is located at approximately the same position as the bottom surface portion 20 of the case body 2,
When the lid 3 is stood upright with respect to the case body 2, the entire back surface 42 of the lid 3 is in contact with the ground, so that the wider the back surface 42 is, the more stable it is when standing. In this invention, the material of the storage case 1 is not particularly limited, so it is not limited to the synthetic resin material as in the above embodiment, but may be made of paper material, for example. In this case, the hinge portion 5 may be made bendable by adhering strong paper or cloth material for reinforcement and connection to the inside and/or outside thereof, or the lid body 3 and the case body 2 may be molded separately. The reinforcing and connecting cloth material, etc. is connected to the lid body 3 and the case body 2 at the corresponding part of the hinge part 5.
The hinge portion 5 may be formed by spanning and joining. According to the above structure, even if the material is made of a material such as paper which is difficult to be pivoted by a pivot shaft, the storage case 1 in which the lid body 3 with the storage portion is openable and closable can be molded, and is excellent in practicality. In this invention, the storage part forming piece may be in the shape of a planar ladder like the holding piece in the above embodiment, or may have any other suitable shape, and may also be shaped according to the type of items to be stored in the storage case. Of course, there are no particular limitations on the use.

[Effect of the idea]

In this invention, since the case body and the lid body are integrally formed, there is no risk of the lid body coming off from the case body. In addition, since the lid can be unfolded at approximately 90 degrees without having to be turned over, the lid can be opened and placed in the upright unfolded state without having to hold down the items stored in the holding piece with your hands. . If you want to close it, just strongly rotate the lid toward the case body. In addition, since the pivot point for opening and closing the lid is almost the same as the grounding point, the back of the lid can be installed in a horizontal position flush with the bottom, or it can be installed in an inclined position with the lid slightly tilted forward. It can be installed easily and has excellent stability. Furthermore, since the case body is completely empty in the above-mentioned upright and unfolded state, it can be used as a space for placing tape cassettes and other appropriate items. The placed object acts as a weight to increase the stability of the standing lid.
