TRAY OF SMALL SIZE WITH BACKGROUND AND COVER

OBJECT OF THE INVENTION

It is object of the present invention, as the title of the invention establishes, a tray of small size with bottom and lid, where the lid fits on the bottom, serving for conservation, protection, storage, transport and consumption of fruits and vegetables in cardboard base.

It characterizes to the present invention the special configuration and design of the die-cut cardboard sheets from which both the base and the cover are configured in such a way that optimum stacking is achieved, where the cover and the base are designed in a way that allows the opening and closing reversible until its complete consumption, being 100% reusable, recyclable and compostable together with the rest of the food.

Therefore, the present invention is circumscribed within the scope of trays made of cardboard that have a base and a lid.

BACKGROUND OF THE INVENTION

In the state of the art, cardboard trays for fruits formed from a sheet of punched and cut cardboard are known. Some of the trays are designed so that they incorporate flaps in the form of a lid that cover the interior space of the tray.

Among all the previous trays some of them have a bottom and a lid as separable elements that can be placed one on top of the other, but they have a large size and they are not fittable nor do they have a closure based on a particular design of tabs and triggers, which prevent the separation of both, making them fully solidary during use.

In the state of the art, the trays described in the register publications FR2710321, US3547722, FR2336042 are known, but none of them has a cover.

On the other hand, the trays of small size that are known are also made of materials such as expanded polystyrene, polypropylenes, etc.

On the other hand, trays are unknown that in addition to having a bottom and a lid, are manufactured in cardboard and designed in a way that they fulfill a multiple functionality, on the one hand they can be stacked, they serve as protection, they allow directly the consumption and they count on a reversible opening and closing, being able to be reusable, recyclable and even compostable with the food contained inside.

Therefore, it is the object of the present invention to overcome the disadvantages pointed out by developing a tray of small size with bottom and lid as described below and is included in its essence in the first claim.

DESCRIPTION OF THE INVENTION

The object of the present invention is a small-sized tray with a bottom and lid that allow the closing and opening of the reversible way.

Both the bottom and the lid are formed from sheets of cardboard cut and cut with an equal geometry but of different dimensions, so that the lid and the bottom are formed, it is possible to proceed to the fitting and full assurance of position and anchoring of the lid on the background reversibly either inside or outside.

Both film s have a polygonal base octagon shaped chamfered corners where are smaller than the largest opposing sides of which both front ends emerge as jambs.

The first trapezoidal extensions with a slight inclination emerge from the front ends or from the gualderas, from which trapezoidal second extensions emerge. The first trapezoidal extensions serve to form the side walls on the chamfered corners of the base, while the second lateral extensions serve to be able to glue or adhere on the gualderas or end walls.

A flange emerges from the sheet used to form the bottom on the free edge of the end walls and of the gualderas, which folded over the end piece or gualdera from which it emerges serves to anchor the cover on the bottom in a reversible manner.

Thanks to the constructive characteristics a tray for conservation, protection, transport and consumption of fruit and vegetables in cardboard is obtained, with the possibility of optimal stacking and with reversible closing and opening functionality until its complete consumption, 100% reusable, recyclable and compostable together with rest of food

A positive aspect of the tray object of the invention is that it improves sustainability due to the maximum possibility of recycling the material when the two pieces (basket and lid) are made on a cardboard basis.

In addition, the cover can be reversibly pivoted on the bottom and logistical optimization is achieved in transport and storage for complete ease of stacking. It also offers the maximum possibility of graphic and identification printing on a paper basis.

Thanks to the designed geometry, a faithful reproduction of the product and an optimal geometric structure are achieved in reduction of handling, storage and transport costs, it also offers the possibility of 100% composting together with the remains of fruits, sauces and other foods.

Unless otherwise indicated, all technical and scientific elements used herein have the meaning commonly understood by one of ordinary skill in the art to which this invention pertains. In the practice of the present invention, methods and materials similar or equivalent to those described in the specification can be used.

PREFERRED EMBODIMENT OF THE INVENTION.

In view of the figures, a preferred embodiment of the proposed invention is described below.

Figure 2 shows the bottom (1) and the lid (2) of the tray in the open position, where the lid (2) is capable of being reversibly anchored with respect to the bottom, as shown in FIG. Figure 1.

The background adopts an approximate configuration of an inverted trunk of an eight-sided base pyramid, not all equal, while the cover (2) adopts a configuration, also approximate, in the position represented also of the inverted trunk of an eight-sided base pyramid and that is fit on the bottom.

Figure 3 shows the sheet of cut and cut cardboard from which the bottom is formed, and which as can be seen comprises a base (3) with polygonal shape, preferably with eight sides, where four of the sides are greater length and they are faced two to two and where the corners (4) of the base are smaller length of the rest of the sides of greater length.

From the base (3) there emerge some end walls (5) that are provided on their free edge and centered to the length of the free edge with anchoring tabs (5.1). From the base (3) protrudes (6) emerge from the lateral long sides, which are also provided on their free edge and centered on the length of the free edge with anchoring flanges (6.1).

From the end walls (5), which can also be from the gualderas (6), a first irregular trapezoidal extension (7) emerges from its free lateral edges, from which a second irregular trapezoidal extension (8) emerges that serves as the glued and fixed on the gualdera (6).

At the bottom of the base (3) there is a series of perforations (3.1) that serve for better ventilation of the products contained inside.

Figure 4 shows the sheet of cut and cut cardboard from which the cover (2) of the tray is formed, which as can be seen, and as in the case of the bottom, comprises a base (9). ) with a polygonal shape, preferably with eight sides, where four of the sides are longer and face two to two and where the corners (14) of the base are shorter than the rest of the longer sides.

From the base (9) emerge a front (10) and the lateral sides of the base (9) some gualderas (11).

From the end walls (10), which can also be from the gualderas (11), a first irregular trapezoidal extension (12) emerges from its free lateral edges, from which a second irregular trapezoidal extension (13) emerges which serves for the glued and fixed on the gualdera (11).

At the base (9) close to the folding lines with the ends (10) and with the gualderas (11) there are defined openings (9.1) that can be extended by the end walls, in combination with the perforations (3.1) from the bottom base (1) the free circulation of air inside is improved.

Additionally, they can also count on perforations (9.2) made in the bottom of the base (9).
