Abstract

A receptacle in book form for a video or audio cassette consists of two covers combined together by a spine. The covers are formed of a cardboard or paper layer 4 and a plastics layer 5 which are held together by an adhesive layer 10, the plastics layer 5 being deep-drawn to define spaces 7 for accommodating the cassette. <IMAGE>

Description

SPECIFICATION Receptacle The invention relates to a receptacle in book form, made by using plastic and consisting of two "book covers" which are connected and held together by means of a "spine". One use to which the present invention may be put is to provide a receptacle for video or audio tape cassettes.

Known receptacles of this type consist of an inner deep-drawn plastic layer, a stiffening layer made of cardboard laid over the latter, a second plastic layer positioned thereon, and welded to the first plastic layer at the margins, sheets indicating the content of the receptacle and laid on the second plastic layer and, finally a transparent plastic film covering the sheets. Both the materials cost and the production costs of such a receptacle are very high. Furthermore, its relatively heavy weight is felt to be a disadvantage.

Accordingly the present invention provides a receptacle in book form, formed of synthetic plastics material comprising two "covers" joined to each other by a "spine", the inner space of the receptacle being formed by a plastic layer, characterised in that the receptacle consists, on the outside, of a cardboard or paperboard layer and, on the inside, of a plastics layer forming, at the same time, the inner space, and in that there is provided between the cardboard or paperboard layer and the plastic layer and adhesive layer holding the two said layers together.

It has been shown, surprisingly, that several advantages are obtained simultaneously thereby.

The production costs of such a receptacle are substantially lower than those of the known receptacle since, here only two layers are necessary, and these can be glued to one another in a very simple and cheap way. This also results in a reduction in the weight of the receptacle in comparison with the state of the art described.

The stability of the receptacle and, in particular, also that of the "spine" which connects the two "covers" to one another in one piece, is completely sufficient for receiving any articles, for example a video or audio tape cassette, and to that extent, is not inferior to the stability of the known receptacles. Added to this is the further advantage that any printing whatever can be applied to the outside of the paperboard or cardboard constituting the outer layer. Such printing can have not only the designation of the receptacle, any particulars of the firm name or trade mark of the manufacturer, etc., but also, for example, in the case of pre-recorded cassettes references and pictures relating to their content.

Thus it is often customary to buy video cassettes, the tape of which is recorded with a cinema film.

In these cases the cassettes are provided on the outside with pictures, an indication of the names of the actors in this film, etc. A print of this type can, however, be applied directly to cardboard or paperboard, whereas in the known receptacles this can only be carried out by inserting appropriately printed sheets and then covering these externally with said transparent plastic film.

Consequently, the characteristic visual appearance of the "book" is expressed substantially better by means of invention, at lower production costs, than in the case of known receptacles.

In the drawings.~ Figure 1 shows an exemplary embodiment of the invention opened out, Figure 2 shows a section along the line Il-Il in Figure 1, Figure 3 shows the receptacle according to Figures 1 and 2, in the closed position.

The book shaped receptacle consists of the two covers 1, 2 joined by a "spine" 3. The above mentioned parts are formed by a common outer cardboard or paperboard layer 4, and an inner, likewise common plastic layer 5, these being connected firmly to one another by means of an adhesive layer 10. In this process, a heat-reactive adhesive is activated in a press as a result of the application of heat, the two layers 4, 5 are glued to the other.

The plastic layer 5 is preferably polystyrene which not only has a relatively low specific gravity, but is also distinguished for relatively low raw material costs. This is the preferred embodiment of the invention. However, alternative plastics such as polyvinylchloride may also be used.

The plastic layer 5 is formed by deep-drawing so that it forms the margins 6 of the inner spaces 7, preferably on the two "covers" 1, 2 with the result that the inner spaces of these covers have approximately the same depth. Furthermore, the film 5 can also have outward embossed portions or the like 8 which, when cassettes are stored, penetrate into the apertures of the cassette spools and hold them firmly.

The outer side of the paperboard or cardboard layer 4 can be provided with a print shown as the layer 9. It should be noted, at this juncture that in the sectional representation of Figure 2 the various layers have been shown relatively thicker than they are in reality, for graphical reasons.

All the features illustrated and described as well as their combination with one another are material to the invention.
