Abstract

PROBLEM TO BE SOLVED: To prevent stacked cases for tape cassettes from falling down. SOLUTION: A pocket sheet material 6 with mirror finishing applied with a high coefficient of friction is fused to a case body 1a so that an outer face 7 of the pocket sheet material 6 is level with or protruding from the outer face 4 of the case body 1a, and the outer face 7 of the pocket sheet material 6 is in contact with the surface of the case body 1a when the cases are stacked, thereby obtaining a good reliability that they do not fall down.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape cassette storage case.

[0002]

2. Description of the Related Art A conventional tape cassette storage case will be described below with reference to FIGS. FIG. 3a is a front perspective view of a conventional tape cassette storage case, FIG. 3b is a perspective view of the rear surface of the storage case, and FIG. 4 is a cross section cc of the case body 1a of the storage case 1 and the pocket sheet material 2. It is an enlarged view of ′. Further, FIG. 5 shows a state in which the storage cases 1 are stacked, and FIG. 6 is an enlarged view of the contact portions on the front surface a and the back surface b of the case body 1a in the stacked state of the storage cases 1.

As shown in the figure, the storage case 1 is composed of the pocket sheet material 2 of the case body 1a, and the pocket sheet material 2 has pockets on the surface A portion of the case body 1a and the back surface B portion of the case body 1a. The sheet material 2 is welded and attached to the main body case 1a in an L-shape so that the outer surface 3 of the sheet material 2 is lower than the outer surface 4 of the case body 1a. Further, as apparent from FIG. 6, when the storage cases 1 are stacked, the pocket sheet material 2 does not come into contact with the upper surface 5a of the case body 1a.

[0004]

In this tape cassette storage case, when the storage cases are stacked, the entire surfaces of the case bodies do not contact each other, and the case body is made of a polypropylene resin having a hinge characteristic. Since the front and back surfaces are textured to prevent scratches, they are extremely slippery, causing the inconvenience that load collapse tends to occur due to vibration or external force when the storage cases are stacked or moved with the storage cases stacked. Was there.

The present invention prevents the collapse of loads when stacked,
It is an object of the present invention to provide a storage case for a tape cassette that can be easily moved while the storage cases are stacked.

[0006]

In order to solve this problem, in the tape cassette storage case of the present invention, when the storage cases are stacked, a pocket sheet material having a mirror-finished surface having a high friction coefficient is provided on the surface of the storage case. To abut,
The configuration is such that it is attached to the main body case so as to be the same or convex with respect to the outer surface of the case main body, thereby improving the frictional force and making it difficult for the load to collapse when the storage cases are stacked.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The invention according to claim 1 of the present invention is such that the outer surface of the pocket sheet material of the storage case for the tape cassette is welded to the case body so as to be the same as or convex to the outer surface of the case body. It is attached, and has the effect of increasing the contact surface when the storage case bodies are stacked.

According to a second aspect of the present invention, the outer surface of the pocket sheet material is mirror-finished, and the frictional force of the contact surface when the storage cases are stacked improves.
It has the effect that the storage case does not slip easily. Claim 3
The invention described is one in which the outer surface of the pocket sheet material has a satin finish, and the storage case becomes less slippery due to the improved frictional force of the contact surface when the storage case is stacked, and the pocket sheet material surface is scratched. Has the effect of preventing

According to a fourth aspect of the present invention, the outer surface of the pocket sheet material is embossed, and when the storage cases are piled up, the frictional force of the contact surface is improved so that the storage cases are less likely to slip and , And has an effect of preventing the surface of the pocket sheet material from being scratched. Embodiments of the present invention will be described below with reference to FIGS. 1a and 2b.

The same components as those of the conventional tape cassette storage case shown in FIGS. 3 to 6 are designated by the same reference numerals and detailed description thereof will be omitted. (Embodiment 1) FIGS. 1A and 1B are cross-sectional views of a case body and a pocket sheet material of a tape cassette storage case according to an embodiment of the present invention, and FIG. 2 shows a state in which the same tape cassette storage case is stacked. It is an enlarged view of the contact portion of the front surface and the back surface of the case body.

In the figure, a storage case 1 is a case body 1.
a and the pocket sheet material 6 and the outer surface 7 of the pocket sheet material 6 is the outer surface 4 of the case body 1a.
Are formed in the same or convex shape with respect to each other, and when the outer surface 7 of the pocket sheet material 6 is stacked with the storage case 1,
The case body 1a and the surface 5a are in contact with each other. Further, the surface 7 of the pocket sheet material 6 is mirror-finished with a high friction coefficient to make it more slippery.

In the above description, an example in which the pocket sheet material is mirror-finished has been described, but the present invention can be similarly applied to satin finish / texture. The surface is also protected from scratches.

[0013]

As described above, according to the tape cassette storage case of the present invention, when the storage cases are stacked, the outer surface 7 of the pocket sheet material 6 having a mirror-finished surface having a large friction coefficient is the surface 5 of the case body 1. By bringing them into contact with each other, a frictional force is generated, and it is possible to obtain an advantageous effect of preventing the collapse of the loads and simplifying the moving operation of the stacked storage cases.
