Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel tape cassette sealing structure. More specifically, the present invention aims to provide a novel tape cassette sealing structure that simplifies the packaging of the tape cassette and maintains the sealing property, which is one of the packaging functions.

[0002]

2. Description of the Related Art A tape cassette, for example, a video tape cassette is placed in a cassette storage case and wrapped with a polypropylene film from above to be packaged.

That is, in FIGS. 8 and 9, a is a video tape cassette, b is a cassette storage case, the video tape cassette a is put in the cassette storage case b, and the whole is a polypropylene film c.
Wrapped and wrapped by.

As a result, in addition to the sealing, protection against dust and rubbing is provided, and further, the exterior of the product is designed.

[0005]

By the way, in recent years,
From the viewpoint of protection of the global environment, there has been a demand for the simplification of packaging and the reduction of packaging materials in place of the whole packaging by polypropylene film.

[0006]

In order to solve the above-mentioned problems, the tape cassette sealing structure according to the present invention is a cassette storage case in which only one surface is opened and the tape cassette can be taken in and out only from one direction through the opening. A tape cassette sealing structure in which a tape cassette is housed inside, and a sealing tape is wound around the cassette housing case so as to close a part of the opening, the surface of the cassette housing case in which the opening is formed, that is, A short perimeter is formed in any part of the opening except for both ends, and the perimeter in the direction crossing the opening is shorter than the perimeter of the other part in the same direction. It is a tape wound.

[0007]

Therefore, in the tape cassette sealing structure of the present invention, as long as the packaging material is a sealing tape having a width and a length enough to wind a part of the cassette housing case housing the tape cassette. Sufficiently, packaging materials will be greatly reduced.

Moreover, since the sealing tape is wound around the short perimeter, the opening surface of the cassette storage case cannot be opened unless the sealing tape is broken. Therefore, another sealing tape is required. The sealability, which is one function, is not impaired.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the sealing structure of the tape cassette of the present invention will be described below with reference to the illustrated embodiments.

In this embodiment, the present invention is applied to packaging a video tape cassette.

In the figure, 1 is a video tape cassette, and 2 is
Is a cassette storage case for storing the video tape cassette 1.

The cassette storage case 2 is made of thick paper, soft synthetic resin, or the like and has a flat box shape in which the video tape cassette 1 can be received almost exactly, and one of the narrow side surfaces located in the longitudinal direction is opened. It is referred to as Part 3.

The depth D of the cassette storage case 2, that is, the depth in the width direction is slightly larger than the front-back width F of the video tape cassette 1.

The large side surface portion 4 of the cassette storage case 2,
Notches 5 and 5 are formed at a substantially central portion of the side edge of the opening 4 on the side of the opening 3 in the length direction. The notches 5 and 5 are formed in a trapezoidal shape in which the length C at the opening edge is larger than the length B at the inner edge.

When the tape cassette 1 is housed in the cassette housing case 2, the tape cassette 1 is slightly retracted from the opening surface of the cassette housing case 2 as shown in FIGS.

Reference numeral 6 is a sealing tape, the width A of which is smaller than the length C at the opening edge of the cutout 5.

The sealing tape 6 having the tape cassette 1 housed therein is wound around the opening 5 in the notch 5 forming portion of the cassette housing case 2 and the ends 6a and 6b thereof are bound together. . The ends 6a, 6
The binding of b may be appropriately selected depending on the material of the sealing tape 6, such as by adhesion when the material of the sealing tape 6 is paper, by heat sealing when it is a film made of a thermoplastic synthetic resin such as polypropylene. . It is also possible to form the sealing tape 6 from a plastic film which has been stretched in the longitudinal direction in advance in a ring shape larger than the peripheral length of the wound portion, and shrink the sealing tape 6 by heat while being fitted onto the predetermined portion. .

As described above, when the sealing tape 6 is wound around the cassette storage case 2, the length thereof is the cutout portion 5 of the cassette storage case 2 with the tape cassette 1 stored.
If the peripheral length of the forming portion in the direction crossing the opening surface, that is, the thickness of the cassette storage case 2 is E, then 2 ·
(F + α) + 2 · E (α is the thickness of the material of the cassette housing case 2), and it is the peripheral length in the direction crossing the opening surface of the cassette housing case 2 at a portion other than the cutout 5 forming portion, That is, it becomes shorter than 2 · (D + α) + 2 · E, that is, 2 · (F + α) + 2 · E <2 · (D + α) + 2 · E, so even if the sealing tape 6 is slid and removed, The side edge of the notch 5 is caught and cannot be slid.

Therefore, once the sealing tape 6 is wound as described above, it cannot be removed unless it is broken, and although the sealing tape 6 is extremely simple and has a small amount of material, the sealing property, which is one function of the packaging, is sufficient. Can be maintained at

If the width A of the sealing tape 6 is equal to or smaller than the length B of the inner edge of the cutout 5, that is, A
If ≦ B, even if the depth D of the cassette storage case 2 and the front-rear width F of the tape cassette 1 are the same, by winding the sealing tape 6 around the inner edge of the notch 5, the perimeter of the tape is different from that. Since it is slightly shorter than the perimeter of the portion (due to the thickness of the material of the cassette housing case 2), the sealing tape 6 cannot be slid and removed.

Further, as shown in FIGS. 7 (a), (b) and (c), the end portions 6a, 6 of the sealing tape 6 which are bonded to each other.
If the slit 7 is formed on one side of b, when the end portions 6a and 6b are to be peeled off at this bonding location, the location of the slit 7 will be broken and it will not be possible to restore the original state. The sealing property is further ensured, and it is particularly effective when the material of the sealing tape 6 is paper.

Further, when the sealing tape 6 is formed of paper, it is easy to dispose of the waste after it is opened, and it is preferable from the viewpoint of global environment conservation.

[0023]

As is clear from the above description, the sealing structure of the tape cassette of the present invention has a structure in which a tape cassette is opened in only one surface and the tape cassette can be taken in and out only in one direction through the opening. A tape cassette sealing structure comprising a tape cassette and a sealing tape wound around a cassette storage case so as to cover a part of the opening, wherein the surface of the cassette storage case on which the opening is formed, that is, an opening surface. A short perimeter with a perimeter in the direction transverse to the opening surface shorter than the perimeter of the other part in the same direction is formed in any part except both ends of the sealing tape. It is characterized by being wound.

Therefore, in the tape cassette sealing structure of the present invention, if the packaging material is a sealing tape having a width and a length enough to wind a part of the cassette storage case storing the tape cassette. Sufficiently, packaging materials will be greatly reduced.

Moreover, since the sealing tape is wound around the short perimeter, the opening surface of the cassette storage case cannot be opened unless the sealing tape is broken. The sealability, which is one function, is not impaired.

It should be noted that the specific shapes and structures shown in the above embodiments are merely examples of the implementation of the present invention, and the technical scope of the present invention is limited by these. Should not be interpreted as.
