Book-shaped case for cassettes

Description;

The invention relates to a book-shaped case for cassettes or video cassettes, which has a spine made of flexible material such as plastic and two shell-shaped deep-drawn parts attached to it, which complement one another and accommodate a cassette.

Such book covers can be opened like a book in order to insert a cassette into the deep-drawn parts forming the inside of the cover or to remove a cassette from the deep-drawn parts. The shell-shaped deep-drawn parts complement each other in such a way that when the cover is closed they are held together with a kind of snap fastener so that the cover cannot open by itself and therefore undesirably. 20

In known book-shaped covers of this type, the shell-shaped deep-drawn parts are relatively stiff due to the material used and the deep-drawn shape and serve to stiffen the cover. Therefore, the cover is relatively unstable and gives a cheap impression. Sheets glued to a relatively thin spine, which indicate the contents of the cover, come off relatively easily at the edges, so that these covers look worn and unsightly after only a short period of use.

The invention is based on the object of creating a book-shaped housing for cassettes such as video cassettes, which has a higher overall stability and has an attractive appearance even after a long period of use.

To achieve this object, it is proposed according to the invention that between de» Back of the cover and each of the two 1n the cover arranged L

each of the hollow-shaped deep-walled parts has a plate-shaped reinforcement J

arranged 1st. In this way, the inventive bow-shaped

stable back/ while the flexibility of the back between the

Deep-drawn parts are not affected 1st/ because there is no

stiffening inserts are located on the back.

Even after a long period of use, such a cover will not become worn and therefore look cheap.

According to a preferred practical embodiment, the back is designed as a shell that accommodates the reinforcements and is welded to the deep-drawn parts along a recessed, circumferential seam. The back thus rises three-dimensionally above the circumferential weld seam/ whereby

the back is compact and stable/ although its ■

outer part is a flexible plastic film. 20

The inserted plate-shaped reinforcements are conveniently inserted into the relevant deep-drawn parts in such a way that displacement of these reinforcements within the back is not possible.

According to a further feature of the invention, at least one leaf-shaped sheet can be attached to the outside of the back of the cover, the edge areas of which are laid over the sides of the shell-shaped three-dimensional back. This effectively prevents

give the cover an unclean, unsightly appearance. 35

The book-shaped cover according to the invention can initially be manufactured without labels or stickers and stored. Depending on requirements, stickers can be attached as final equipment when corresponding cassettes are packaged. The stickers can be applied to the outside or back of the cover and the cassettes can be inserted in one step.

The invention creates an extremely stable and versatile uucn-shaped cassette for cassettes such as video cassettes/ which has an attractive appearance or external appearance even after a long period of use/ because this cassette has a stable spine on the one hand and stickers attached to its outside cannot be accidentally removed at the edge of the spine on the other hand/ because such stickers can be pulled down over the edge of the relatively thick spine.

The drawing shows an embodiment of a book-shaped cover according to the invention.

Fig. 1 a view of the inside of the unfolded cover and Fig. 2 shows a cross-section of the casing along line II-II of Fig. 1. A book-shaped cover (1) for video cassettes has a

a back (2) made of flexible material such as soft plastic film, in which shell-shaped deep-drawn parts (3 and 4) are arranged, which can complement each other to form a box-like cavity for receiving the video cassette (not shown). For this purpose, the deep-drawn part (3) has a raised edge (5) which ^can receive an edge (6) on the deep-drawn part (4) which is raised and set back inwards. When the cover (1) is closed, both deep-drawn parts (3 and 4) are held together with a kind of snap fit and do not accidentally come apart.

01e Deep-drawn parts (3 and 4) are welded to the plastic film of the back (2) along a circumferential and recessed weld seam (7).

Between each deep-drawn part (3 and 4) and the foil of the back (2) there is a relatively thick plate (8 or °), which in the present example is made of cardboard. The weld seam (7) between the foil of the back (2) and the relevant deep-drawn part (3

can move within the back (2). This ensures that between the two deep-drawn parts (3 and 4) there is a flexible section (10) that allows the cover to be opened and closed.

As shown in particular in Fig. 2, the seam (7) is set back in such a way that on the outer edge of the back (2) there is a flat edge region (12) running almost perpendicular to the outer surface (11) of the back (2). This edge region (12) can be used to form the edge of arches arranged on the outer surface (11) of the back (2), such as

stickers so that these edge areas of the sheets do not

A sheet carrying information about the contents of the cassette or

The sticker is conveniently applied to the spine (2) of the opened case (1) immediately before or after a cassette has been inserted. The case is then closed, which is now ready for shipping and use.

The base of the deep-drawn part (3) has two bulges (13) that can be used to center the inserted cassette. However, these bulges are not absolutely necessary.
