Description

DESCRIPTION

Cardboard container with lid for food products

TECHNIQUE SECTOR

The present invention refers to a container for food products, such as fruits or vegetables, prepared meals or other foods, of the type used in refrigeration equipment in service stations, supermarkets, etc.

The object of the invention is to provide an ecological, recyclable and compostable packaging, which facilitates production for companies that sell their packaged products to supermarkets, so that with the same container they can serve different large surfaces, either finishing them with the classic heat sealing or implanting a cardboard lid, thus reducing the use of plastics to 0%.

BACKGROUND OF THE INVENTION

In the scope of practical application of the invention, it is common for certain types of food to be supplied in tray-like containers made of plastic materials, such as PET, which represents a serious environmental problem.

Trying to avoid this problem, boxes or containers made of corrugated cardboard are known on the market, determining in their assembly a container provided with wings or perimeter cantilever in its upper part that makes it possible to close it using a heat-sealed plastic film.

In recent years, these containers have meant a very substantial environmental improvement compared to those originally used, which were completely made of plastic.

Even so, today's society is increasingly demanding and people are beginning to question even whether the heat-sealing lid is made of plastic.

There is a current trend in many supermarkets towards “0 plastic”, which means rejecting any packaging that incorporates plastic in any of its parts, even in minute quantities.

EXPLANATION OF THE INVENTION

The packaging for food products that is recommended solves the previously mentioned problem in a fully satisfactory manner, based on a simple but effective solution.

To this end, and more specifically, the container of the invention is constituted from the development of a sheet of die-cut cardboard with folding lines in which a sector or rectangular base is defined, with its chamfered or rounded vertices, whose edges respective determining sectors emerge from the larger and smaller walls of the container, which are linked to each other from some sectors emerging from the sides of said walls, determining a body in the shape of an inverted pyramid trunk, open at the top, with a horizontal overhang that It extends exteriorly and perimeter.

Based on this conventional structuring, which allows the mouth of the container to be heat-sealed in a conventional way using a plastic sheet, it has been planned that the container is complemented with an independent cardboard lid, to be used selectively to replace said plastic sheet. heat-sealed, which is attached or adhered to said container.

According to a first variant embodiment of the invention, the lid has a plan configuration according to the perimeter defined by the horizontal overhang of the mouth of said container, so that said sheet will present lateral expansions that fold over the side walls. larger side walls of the container, including tabs that can be locked in respective slots made on said larger side walls of the container.

In a second embodiment variant, the lid has a plan configuration according to the perimeter defined by the horizontal overhang of the mouth of said container, so that said sheet has lateral expansions that fold over the larger side walls of the container, and They are fixed to it by gluing once the container is filled.

Finally, and according to a third embodiment variant, the lid has a plan configuration according to the perimeter defined by the horizontal overhang of the mouth of said container, so that said sheet will present lateral expansions that fold over the side walls. larger than the container, including each of these expansions a tab lockable in a slot provided in the edge of the cantilever that emerges from the larger side walls of the container.

In any of the three embodiment variants, since the lid is independent of the container, the same container can be used in some cases to be closed by heat sealing (according to the known state of the art) or to be closed with a cardboard lid as as described in the present invention.

In this way, a plastic-free, 100% ecological packaging is achieved.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, it can be seen how the container of the invention is constituted from the development of a sheet of die-cut cardboard with folding lines in which a central rectangular sector determining the bottom (1) is defined, with its chamfered or rounded vertices, and from whose edges emerge respective determining sectors of the larger (2) and smaller (3) side walls of the container, which are linked to each other from sectors (4) emerging from the sides of said walls, and that form the rounded or chamfered edges of the container. These sectors (4) can emerge from the sides of the larger walls as shown in the attached figures, but they could also emerge from the sides of the smaller walls. When assembled, the container is configured as a body in the shape of an inverted pyramid trunk, open at the top, with a horizontal overhang (5-5') that extends externally and perimeter, emerging from the major (2) and minor (2) side walls ( 3) of the container.

In accordance with the essence of the invention, the container is complemented with a closing lid made of a cardboard sheet (6) with dimensions according to the external perimeter defined by the horizontal overhang (5-5'), a lid that is independent. of the container. In a first embodiment variant, the one shown in Figures 1 to 4, the sheet (6) has lateral expansions (7) that emerge from the longer sides and end in tabs (8). selectively lockable in windows (9) made on the larger side walls (2) of the container.

In this way, and as shown in Figures 2 to 4, the lid can be easily fixed and removed manually on the container by elastic deformation of the tabs (8), including a foldable intermediate sector (8') that in The assembly tends to unfold, causing the lid to remain firmly blocked.

According to a second variant embodiment of the invention, the one shown in Figures 5 to 7, the container may lack the aforementioned windows (9) so that the sheet (6) that constitutes the lid itself includes lateral expansions. (7') with an intermediate fold line (10) that defines an end sector (11) that is fixed by means of adhesive (once the container is filled and with the corresponding machinery), to the larger side walls (2) of the container, as seen in Figure 7. This embodiment is therefore focused on containers that are closed automatically after filling and are easy to use. That is, once opened, they cannot be closed again, since the lid is configured to open by tearing through the area in which the lateral expansions (7') are folded.

Finally, and according to a third embodiment variant, the one shown in Figures 8 to 12, the container may lack the aforementioned windows (9) so that the sheet (6) that constitutes the lid itself includes lateral expansions. (7'') that end in a tab (8), lockable in a slot (9') provided on the edge of the horizontal cantilever (5) that emerges from the larger side walls (2) of the container.
