Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a storage case for storing and storing a tape cassette wound with a tape such as a magnetic tape.

[0002]

[Prior Art]

 Conventionally, tape cassettes have been handled in a storage case for sale and storage. The case is a rectangular case that houses the magnetic tape cassette, and a transparent hinge is provided with a lid that can be opened and closed. Cases are used.

[0003]

[Problems to be solved by the device]

 Since the conventional storage case is made of a transparent material of polystyrene resin (GP-PS), it often cracks, cracks, or breaks when the storage case is dropped, and has a high impact resistance. If the entire case is made of a resin material, for example, a high impact polystyrene resin material (hereinafter referred to as HI-PS), the stored tape cassette cannot be seen and the product value is reduced, which is a problem. The present invention aims to properly eliminate these conventional drawbacks by improving the impact resistance around the storage case, reducing the cracks and chips caused by dropping, and facilitating the tape cassette contained in the case. The purpose of the present invention is to provide a tape cassette storage case that looks good and looks good and is easy to handle.

[0004]

[Means for Solving the Problems]

 The present invention comprises a transparent or translucent case body capable of accommodating a tape cassette, and a lid body pivotably attached to the case body with a hinge portion, and a pair of hub rotation preventing projections are provided inside the case body or the lid body. In a tape cassette storage case equipped with, the case main body and / or the lid body is formed of a first synthetic resin material having excellent impact resistance, and the other portions are transparent second synthetic resin material. It is a tape cassette storage case characterized by being formed by.

[0005]

[Action]

 In the case of the present invention, when the magnetic tape cassette is housed in the case main body 1, the hub rotation preventing projections 9 and 9 can be fitted into the hub holes of the tape cassette and the positions thereof can be regulated and held, and the case is housed in the case. The tape cassette can be easily seen from the transparent second synthetic resin material, and even if the case is accidentally dropped, the area around the case is the first synthetic resin material that has high impact resistance, so it can be used safely without damage. You can

An embodiment of the present invention will be described with reference to FIGS. 1 to 3. A transparent or translucent case body 1 capable of accommodating a tape cassette is provided with a lid 3 pivotably attached with a hinge portion 2 so as to be opened and closed. In a tape cassette storage case provided with a pair of hub rotation preventing projections 9 and 9 inside the case body 1, the two-color molding means surrounds the case body 1, for example, a side wall portion or a part of this and a bottom wall portion. The first synthetic resin material 4 containing, and having excellent impact resistance, such as HI-PS (high-impact polystyrene resin), ABS (acrylonitrile-butadiene-styrene copolymer resin), ACS (chlorinated polyethylene-acrylo resin). Nitrile / styrene copolymer resin), AAS (acrylate / styrene / acrylonitrile copolymer resin), etc., and other parts are transparent. Clear second synthetic resin material 5 Case body made of a resin selected from GP-PS (polystyrene resin), AS (acrylonitrile-styrene copolymer resin), PMMA (polymethylmethacrylate resin), etc. 1 and a lid 3 made of a transparent second synthetic resin material, for example, GP-PS resin material 4, constitute a tape cassette storage case. In this case, as the hinge portion 2, a pin is provided on the case body 1 side, and a bearing portion of a pin hole that can be fitted and supported by the pin is provided on the lid body 3 side, but they are in a relative relationship, so However, it is also possible to provide the recesses 11 and the protrusions 12 for fitting on the relative sliding wall surfaces of the case body 1 and the lid body 3 so that they are easily supported. Furthermore, it is preferable that a finger hook portion 6 of a concave portion and / or a convex portion is attached to either the case body 1 or the lid body 3 or any of them so that the lid body 3 can be easily opened. It should be noted that concave portions 7 and 8 into which the head housing of the tape cassette is fitted are formed on the inner surfaces of the case body 1 and the lid body 3 as required. Further, the case main body 1 has at least one side of an upright wall surface of the case main body 1 as an opening, and a side wall extending up to the opening is erected on a bottom wall, and the side wall has a hinge portion. 2 and each other by deploying the cover 3 openably, this is the opening located the frame-like side wall 3 ₁ provided in the lid body 3 side, are to facilitate insertion holding the tape cassette.

In the example of FIGS. 4 and 5, in the case having the same configuration as that of FIG. 1, a plate-shaped base portion 41 made of HI-PS resin material is formed on a part of the bottom wall of the case body _1. If, there is to have the rotation preventing protrusion 9, plate-shaped base portion 4 ₁ is enabled on fabricated to form a state in which the ligated with the peripheral side wall portion of the HI-PS resin material 4 of the case body 1 is there.

[0008] In the embodiment of FIG. 6, formed of a one side of the cover 3 and the opening, which has a notch 3 _2, a side wall portion of the peripheral for example three directions becomes the other side in the HI-PS resin 4 However, the other part is formed of the transparent GP-PS resin material 5, and the rotation preventing projections 9 and 9 are provided on the inner surface of the lid body 3. The case body 1 has a bottom wall. There is no peripheral side wall in the three directions, and a bag-shaped portion ₁₁ is formed on one side edge and the whole is formed of GP-PS resin material 5.

In the embodiment shown in FIG. 7, the tape cassette is stored laterally, and the lid body 3 provided in the case body has a pair of hinge portions 2 on both side walls. Both of the lid 3 and the lid 3 are formed of the HI-PS resin material 4 on the side wall portions, and the other portions are formed of the GP-PS resin material 5. The case body 1 and the lid body 3 are provided with engaging protrusions 11 and engaging recesses 12 that form locking engagement portions at predetermined positions on both sides. This locking part is provided at one or a plurality of positions where the case body 1 and the lid 3 come into contact with each other. The engaging projection 11 is easily fitted into the engaging recess 12 provided on the side wall of the case body 1, but the unevenness may be provided in a relative positional relationship. You may arrange in the opposite.

[Effect of the device]

 According to the present invention, the case main body and / or the periphery of the lid are formed of the first synthetic resin material having excellent impact resistance, and the other portions are formed of the transparent second synthetic resin material. , The impact resistance around the case is improved, cracks and chips can be reduced even if the tape cassette storage case is accidentally dropped, and the tape cassette can be smoothly taken in and out of the case. Retaining the tape cassette is also extremely good, the appearance of the case is good, and the tape cassette can be safely taken in and out, and the tape cassette inside the case can be easily seen and the commercial value of the case increases. In addition, there is a practical effect such as a cheap form.
