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 container, which includes a lid that is part of the container itself, so that it is made from 100% cardboard, 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.

Well, based on this conventional structuring, it has been planned that the container is complemented with a cardboard lid, which forms part of said container as a single piece, emerging from a folding line of the edge of the cantilever associated with one of the largest walls, and presenting a plan configuration according to the perimeter defined by said cantilever, so that in correspondence with the end opposite to the hinged end of the cover, an expansion is included with a tab for fixing by gluing on the corresponding largest side wall. once the container is filled.

According to a second variant embodiment of the invention, replacing the aforementioned tab for fixing by gluing to the larger side wall of the container, the expansion of the lid includes tabs that can be locked in respective slots made on the corresponding larger side wall of the container. container.

These tabs can be combined with an intermediate die-cut sector that folds inwards in the lid coupling, so that it tends to unfold, which causes the tabs to remain firmly interlocked, preventing unwanted movements for them that could cause a accidental opening.

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

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that will be made below and in order to help a better understanding of the characteristics of the invention, in accordance with a preferred example of its practical implementation, a set of plans is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:

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 a truncated inverted pyramid, open at the top, with a horizontal overhang (5-5') that extends outside and perimeter, emerging from the largest (2) and smallest (3) side walls 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) that is part of the container itself, so that it emerges from a folding line (12). located in correspondence with the edge of the horizontal cantilever (5) associated with one of the largest side walls (2), said folding line (12) performing the functions of a hinge.

The sheet (6) will have dimensions according to the external perimeter defined by the horizontal cantilever (5-5'), so that a lateral expansion (7'-7) is included in correspondence with the end opposite to the hinged end of the cover. which in a first embodiment variant presents an intermediate fold line (10) that defines an end sector (11) that is fixed by means of adhesive and once the container is filled to the corresponding larger side wall (2), all of this as and as seen in figure 3. This variant is focused on containers that close automatically after filling and are simple to use (after opening the lid by tearing, it cannot be closed again).

In a second embodiment variant, the one shown in Figures 4 to 6, the lateral expansion (7) of the lid includes tabs (8) that can be selectively interlocked in windows (9) made on the corresponding larger side wall (2) of the container. opposite the lid hinge line

In this way, and as shown in Figures 5 and 6, 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.
