Abstract

<P> Method for producing a package such as a packaging tray for food products, characterized in that a sheet of flexible material 2 is provided with a decoration and / or identification references on one of its faces, this sheet 2 is placed in an injection mold and a transparent plastic material 1 is injected into this mold in order to overmold this plastic material on the face of the sheet provided with the decoration, the plastic material overmolded being of a nature and / or thickness such that it constitutes the stiffening structure of the packaging. </P>

Description

 The invention relates to a method for producing a package such as a packaging tray for food products.

 We already know the trays which consist of two thermoformed plastic shells, which are arranged one inside the other with the interposition of a label. In this case, at least the plastic material constituting the outer shell is transparent, so as to make visible the inscription of the label sandwiched between the two shells and which is thus suitably maintained and protected.

 This manufacturing process is however expensive, insofar as it requires the manufacture of two shells, with specific and expensive machines and, moreover, the packaging obtained is not of good quality insofar as the plastic material used does not allow not to obtain packaging with good temperature resistance and good resistance to deformation.

 The present invention aims in particular to remedy these drawbacks and for this purpose relates to a method for producing a package such as a packaging container for food products, characterized in that a sheet of material is used flexible provided with a decoration and / or identification references on one of its faces, this sheet is placed in an injection mold and a transparent plastic material is injected into this mold in order to overmold this plastic material on the face of the sheet provided with the decoration, the overmolded plastic being of a nature and / or thickness such that it constitutes the stiffening structure of the packaging.

 According to another characteristic of the invention, the flexible sheet is shaped so that it defines all or part of the internal wall of the packaging and the plastic is overmolded on this shaped sheet.

The invention is shown by way of non-limiting example in the accompanying drawings in which
FIG. 1 is a schematic sectional view of a package according to the invention,
- Figure 2 is a perspective view of this package.

 The present invention therefore aims to achieve a simple and inexpensive packaging, insofar as it allows the decoration or labeling of the packaging, simultaneously with its manufacture, this decoration and this labeling being moreover suitably fixed so as not to be moved by the products contained in the packaging and, also, without being able to be torn off or damaged from the outside of this packaging.

 According to the invention, it is thus planned to produce the packaging such as the tray 1, by injection of a transparent plastic material, the injection mold receiving, prior to injection, the plastic material, a sheet of flexible material provided with a decoration or identification references of the packaged product, so that the pasty plastic material covers the decorated face of the sheet thus ensuring, after solidification, its positioning.

 According to this embodiment, the sheet of flexible material therefore forms all or part of the internal face of the packaging, the external face of which is formed by transparent plastic, so as to make the decoration or the labeling references of the product visible. packed up.

 In order to favor the mechanical junction of the external face decorated with the flexible sheet and the plastic material in the pasty state, provision will preferably be made for lacquering on this decorated side of the flexible sheet, so that this lacquer softens in contact with the hot plastic and ensures good mechanical joining of the flexible sheet and the plastic after solidification of the latter.

 In the example shown, the sheet of flexible material 2 is a sheet which covers the entire internal face of the packaging. This sheet, constituted for example by an aluminum sheet, is shaped by pleating at the height of its angles 3, the folded folds of the aluminum sheet being suitably maintained by the mechanical connection of the sheet and the plastic material. transparent.

 This aluminum sheet may include a decoration on the whole of its external face, insofar as the nature of this decoration is such that it is not destroyed by the folds of the sheet at the corners of the packaging. . In this case, however, the identification references will be provided on the flat side and / or bottom faces, so as not to be deformed by the pleating of the sheet.

 It will therefore be noted that, according to the invention, the sheet of flexible material is designed to serve as a support for decoration and to be able to come into contact with the packaged product and, in particular, a food product, while the structure of the packaging itself is obtained by an injected transparent plastic material which does not in itself contain the decoration and which comes into contact with the packaged product only in the zones possibly left free by the sheet of flexible material.

 In the case of the implementation of an aluminum foil, this will preferably cover the entire internal face of the package, as shown in the attached drawings, in order to obtain a packaging of good mechanical strength, with a decoration suitably protected from the outside and which offers good barrier qualities to gases and ultra-violet radiation, even at the corners of the packaging in which the folds are located 3 aluminum foil.
