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 the packaging of a video tape cassette.

In the figure, reference numeral 1 denotes a video tape cassette;
Is a cassette storage case for storing the video tape cassette 1.

The cassette storage case 2 is made of cardboard, soft synthetic resin, or the like, and has a flat box shape in which the video tape cassette 1 can be received almost exactly. One of the narrow side surfaces, which is located in the longitudinal direction, has an opening. Part 3 is provided.

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

A large side portion 4 of the cassette storage case 2;
Notches 5, 5 are formed at substantially the center in the length direction of the side edge of the opening 4 on the side of the opening 3. The cutouts 5, 5 are formed in a trapezoidal shape in which the length C at the opening edge is larger than the length B at the back edge.

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

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

Then, such a sealing tape 6 is wound in a direction crossing the opening surface in the cutout 5 forming portion of the cassette storage case 2 in a state where the tape cassette 1 is stored, and its ends 6a and 6b are bonded. . In addition, the end portions 6a, 6
The binding b may be appropriately selected depending on the material of the sealing tape 6, such as by bonding when the material of the sealing tape 6 is paper, or by heat sealing when the material is a thermoplastic synthetic resin film such as polypropylene. . Alternatively, the sealing tape 6 may be formed in a ring shape larger than the peripheral length of the winding portion with a plastic film that has been extended in the longitudinal direction in advance, and may be shrunk by heat while being fitted to a predetermined portion. .

As described above, when the sealing tape 6 is wound around the cassette storage case 2, the length thereof becomes the notch 5 of the cassette storage case 2 in a state where the tape cassette 1 is stored.
Assuming that 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, 2 ·
(F + α) + 2 · E (α is the thickness of the material of the cassette storage case 2), and it is the perimeter of the cassette storage case 2 other than the cutout 5 forming portion in the direction crossing the opening surface, That is, since it becomes shorter than 2 · (D + α) + 2 · E, that is, 2 · (F + α) + 2 · E <2 · (D + α) + 2 · E, even if the sealing tape 6 is slid and removed, It cannot be slid by being caught on the side edge of the notch 5.

Therefore, once the sealing tape 6 is wound as described above, the sealing tape 6 cannot be removed unless it is broken, and the sealing property, which is one of the functions of the packaging, is sufficiently achieved despite the fact that it is extremely simple and uses little material. Can be maintained.

If the width A of the sealing tape 6 is equal to or smaller than the length B of the inner edge of the notch 5, that is, A
If ≦ B, even if the depth D of the cassette storage case 2 is equal to the front-rear width F of the tape cassette 1, the sealing tape 6 is wound around the inner edge of the notch 5 so that the peripheral length becomes other than that. Is slightly shorter (due to the thickness of the material of the cassette storage case 2) than the peripheral length of the portion, so that the sealing tape 6 cannot be slid off.

As shown in FIGS. 7A, 7B and 7C, the end portions 6a and 6a of the sealing tape 6 adhered to each other.
If the slit 7 is formed on one side of b, if 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 it to its original state. The sealing property is further ensured, and this 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 dust after opening, which is preferable from the viewpoint of global environmental protection.

[0023]

As is apparent from the above description, the sealing structure of the tape cassette of the present invention has an opening on only one surface and a depth at which the tape cassette can be inserted and removed only from one direction through the opening . Front and back width
A tape cassette sealing structure in which a tape cassette is stored in an equal or slightly larger cassette storage case, and a sealing tape is wound around the cassette storage case so as to cover a part of the opening. the but formed surface, i.e. the short comb than the perimeter of the perimeter in a direction transverse to the <br/> opening surface of any of the portion excluding the both ends of the opening surface in the same direction of the other part, in partial It is characterized by winding a sealing tape.
