Description

[Detailed Description of the Invention] The present invention relates to an improvement of a case configured to house a plurality of cassette tapes in parallel.

Conventionally, as a case of this kind, a case was constructed in which a storage frame with both upper and lower sides open, and the opening side of the storage frame was closed with a cover plate and a bottom plate to be assembled, as disclosed in, for example, Japanese Utility Model Publication No. 56-465. disclosed in
And it is put into practical use. However, in this known case, since the member forming the storage frame has rigidity, when the case is folded flat, a part of the storage frame protrudes from the case body and becomes bulky.
The packaging was extremely inconvenient.

The purpose of the present invention is to eliminate the above-mentioned inconvenience, and
To provide a cassette tape storage case which can reduce the number of locking tools required during assembly and allows the cassette tape to be easily taken out.

The case of the present invention will be explained based on illustrated examples.
It is as follows.

As shown in FIGS. 1 to 5, the first side plate 1, the narrow bending plate 2, the cover plate 3, the bottom plate 4, the locking plate 5a, and the second side plate 5b are connected to each other via folding lines. It has been set up. The flexible connecting piece 6, which is narrower than the first side plate 1 and can be bent at any position, allows the third side plate 5b to have a width corresponding to the total width of the first side plate 1 and the bending plate 2 and the same width as the second side plate 5b. A U-shaped frame member 8 is formed by connecting one end edge of each of the fourth side plates 7a and 7b. The other end edges of the third and fourth side plates 7a and 7b of the frame member 8 are
A storage frame 10 whose upper and lower surfaces are open is formed by being joined to opposing edges of the side plate 1. Locking tools 11a and 11b are attached to the inner surface of the locking plate 5a and the outer surface of the second side plate 5b for mutually engaging them. One side edge of a shape-retaining plate 12 is bendably connected to the second side plate 5b, and the shape-retaining plate 12 is bent to the inside of the connecting piece 6 to sandwich the connecting piece 6.

Furthermore, as shown in FIG. 6, one side edge of the shape retaining plate 12 is connected to the second side plate 5b.
The shape-retaining plate 12 is formed on the inner surface spaced inwardly from the outer edge of the second side plate 5b by a height 20 approximately equal to the height of the bent plate 2, and is therefore joined to the outer edge of the second side plate 5b and the inner surface of the second side plate. A step 17 having a height 20 corresponding to the total thickness of the connecting piece 6 and the shape-retaining plate 12 and approximately equal to the height of the bending plate 2 is provided between one side edge of the plate.

First side plate 1, bending plate 2, lid plate 3, bottom plate 4, locking plate 5a, second, third, fourth side plates 5b, 7a, 7b
The shape-retaining plate 12 is formed by covering both sides of a rigid core plate 13 made of cardboard or the like with a flexible synthetic resin sheet 14 made of heat-fusible material such as vinyl chloride, and the connecting portions and outer peripheral edges of these parts are They are joined by welding. Further, in the figure, 15 indicates a raised handle attached to the outer surface of the second side plate 5b, and 16 indicates a recessed notch in the locking plate 5a.

As shown in FIGS. 1 to 3 and 6, the case of the present invention having the above-mentioned configuration has a second side plate 5b on the outer surface of the connecting piece 6 while keeping the storage frame 10 in a rectangular shape. While bringing the inner surfaces into contact, the shape retaining plate 12
are bent inward and the connecting pieces 6 are held in the frame member 8 to retain their shape, and the cassette tapes are stored in parallel inside the storage frame 10, and then the locking plate 5a is It is assembled by overlapping the locking tools 11a and 11b on the outer surface of the second side plate 5b and engaging them with each other. In addition, as shown in FIGS. 4 and 5, in order to fold the locking tools 11a and 11b,
With the shape-retaining plate 12 released from the connection piece 6, the connection piece 6 is folded in as appropriate, and the third and fourth side plates 7a, 7b are bent inward.
The shape-retaining plate 12 is folded inward and overlapped with the inner surface of the second side plate 5b, and then the cover plate 3 and the locking plate are stacked on the inner surface of the bottom plate 4. 5a is bent inward and overlapped with the outer surface of the second side plate 5b, and the locking tools 11a and 11b are engaged with each other, and in the folded state,
The storage frame 10 is completely held inside the case body and does not protrude from the case body.

Therefore, according to the case of the present invention, there is no bulkiness caused by a part of the storage frame 10 protruding from the case body when the case is folded, and the connecting piece 6
It is not necessary to attach a locking tool to the second side plate 5b to maintain the joined state, and when assembling the case, the shape-retaining plate 12 clamps the connecting piece 6 and both edges of the shape-retaining plate 12 are held together. Third and fourth side plates 7a, 7
This prevents the third and fourth side plates 7a and 7b from falling down due to collision with the inner surface of the frame member 8. In other words, the frame member 8 can be kept in a strong rectangular shape.

Furthermore, as shown in FIG. 6 and described above, when the shape retaining plate 12 is bent inside the connecting piece 6 and the frame member 8 retains its shape, the outer edge of the second side plate 5b and the second A step having a height 20 corresponding to the total thickness of the connecting piece 6 and the shape-retaining plate 12 and approximately equal to the height of the bending plate 2 between one side edge of the shape-retaining plate 12 joined to the inner surface of the side plate 5b. 17, when the cassette tape 18 is housed in the case, a gap 19 having a height of 20 is created between the upper inner surface of the second side plate 5b and one shoulder of the cassette tape 18. On the other hand, when the cover plate 3 is bent outward and opened, the bending plate 2 facing the upper side of the second side plate 5b is bent outward and the other shoulder of the cassette tape 18 protrudes. Therefore, even if the case is full of cassette tapes 18 and the user wants to take out one of them, the user can easily take out the cassette tape 18 by hooking his/her fingertips onto both shoulders of the cassette tape 18, which is extremely convenient. It is.
