Description

Compact cardboard tray

Object of the invention

The present invention relates to a tray of compact cardboard that is of preferred application to facilitate the transport and storage of products such as products perishables, containers containing such products or others.

It is an object of the invention that the tray of cardboard is conceived so that it presents a reinforced structure in its corners by columns of high compression resistance that support without deforming the weight of several stacked trays with the products inside.

Background of the invention

Trays in general intended for transport of fruit and vegetable products show a reinforced structure in the corners to support the load of the respective trays that They stack up.

Some solutions include incorporation into the heads or on the lateral sides greater than some extensions that conveniently folded and adhered to said heads or major lateral faces define reinforcing columns in the corners that increase the support surface on which it rests the tray that is stacked superiorly.

In addition, it is contemplated that upper edges of corner braces support a placket that folds from the tester and helps increase the surface area of contact on which the prepared tray is supported superiorly.

The design of corner braces therefore It is very important to provide an adequate distribution of loads that the placket supports, since this can yield by the weight of the upper trays.

The utility model ES 1 049 400 for example, refers to a stackable tray for perishable products in the that the corner reinforcement consists of a prismatic column triangular that has a single support wall in correspondence with each of his legs and hypotenuse, remaining resting a placket on the upper edges of these sides.

In the case of the utility model ES 1 059 148 the triangular corner reinforcement features a double wall of support in one of its legs and simple support walls in the hypotenuse and in the other leg.

The optimization of the conditions of lift in the corners of compact cardboard trays makes feasible the invention described below.

Description of the invention

The compact cardboard tray that constitutes the object of this invention incorporates reinforcement columns in the corners that allow a better distribution of the weight of the trays stacked superiorly optimizing the conditions of sustainability and avoiding deformations.

The reinforcements have a configuration triangular prismatic with mostly reinforced sides in comparison with other solutions known previously. The reinforcements are obtained from lateral extensions to the endowed endowed of bending lines that define four consecutive sectors that are fold, so that the first sector or sector adjacent to the head is attached to the inner side of the side wall of the tray, the second sector is inclined to constitute the hypotenuse, the third sector adheres to the inner face of the testero constituting a double wall and the fourth sector adheres to the inner face of the first sector also constituting a double wall.

The upper edges of these two double walls increase the support surface on which it will be placed in position horizontal a placket that extends superiorly to the tester in the vicinity of each of the corners, which is lowered until resting on the upper edges of said reinforcement of corner. The placket additionally has an extension side that folds down and adheres to the outer face of the side wall in the tray assembly situation.

The tray incorporates in its second sector a upper protrusion that, in its assembly situation, crosses a groove in the placket, penetrates through a hole practiced at the base of the tray that is stacked superiorly and is enter a recess, with a configuration that matches the highlight, defined at the base of the second sector, thus establishing the anchor between trays.

In addition, the testator counts with a top center flap that folds over the inner face of the testero, in which a U-cut is made that define an upper highlight that fits in a central groove practiced in the tray that is stacked superiorly.

In a possible alternative solution you could provide for the possibility of the reinforcement having another sector that would remain attached to the hypotenuse conforming therefore corner reinforcements, which would have a double wall in all its sides, thus obtaining a column of great resistance.

Preferred Embodiment of the Invention

With reference to the figures described then a preferred embodiment of the tray compact cardboard that constitutes the object of this invention.

The tray is formed from the development of a sheet of compact cardboard with folding lines and court that define after their assembly, some heads (1) that present side extensions that conveniently folded constitute corner reinforcements (2) configuration prismatic triangular section, and side walls (3) that they have a wide flap (4) that folds and attaches to the inner face of said side walls (3).

The tray stands out mainly because the corner reinforcements (2) have reinforced walls that allow to support, without deforming, the trays superiorly stacked

These reinforcements (2) are formed from the lateral extensions of the tester (1), which are provided with folding lines that define four consecutive sectors, comprising a first sector (5) that is attached to the inner side of the side wall (3) of the tray, a second sector (6) located in diagonal arrangement, a third sector (7) adhered to the inner face of the head (1) and a fourth sector (8) that adheres to the inner face of the first sector (5), becoming a double wall corner reinforcement in the
legs.

The upper edges of the four sectors (5, 6, 7, 8) constitute the support surface of a placket (9) on the one that rests the upper stacked tray, placket (9) that defines superiorly to the tester (1) and which in turn has a lateral extension (10) that is attached on the outer face of the side wall (2) in the mounting situation.

The second sector (6) has a highlight upper (11) and the placket (9) has a slot (12) through which said upper projection (11) penetrates, also at the base of the tray is a hole (13) intended to receive the upper projection (11) of the lower arranged tray and the second sector (6) is also equipped with a recess at its base (14) configuration similar to that of the upper protrusion (11) for anchor of the latter.

The testero (1) also has a flap central (15) that falls on the inner face of the tester (1), and in the tester (1) a U-cut is defined that defines a central projection (16) that fits into a central groove (17) practiced in the base of the tray that is stacked superiorly.
