STACKABLE TRAY TO CONTAIN PRODUCTS

DESCRIPTION

TECHNICAL FIELD OF THE INVENTION

The present invention encompasses in the field of rigid or semi-rigid containers of polygonal cross-section, specifically cardboard trays, specifically those formed to be able to stack on top of each other.

BACKGROUND OF THE INVENTION

Trays are known with some of their inclined side walls, usually in two of them, in order to improve the support of successive stacked trays and save material from other trays that have supports or roofs on top. Also, these known trays prevent the immediately upper tray from losing support with respect to the vertical of the immediate lower tray, a loss that would result in the direct support of the upper tray on the product contained in the lower tray and the probable deterioration of said product.

Thus, known trays have a limitation in their resistance due to several factors:

1 °) To the configuration of the flaps and sides of cardboard in the direction of the corrugated channel which are those that resist the pressure of the weight of an upper tray.

2 °) To the resistance that the base of the tray has to support the contained weight, bottom flexion (thus known to the deformation of the base of a box due to the bending produced by the moisture absorption of the product).

3rd) To the support of the tray on a pallet.

DESCRIPTION OF THE INVENTION

The present invention is established and characterized in the independent claims, while the dependent claims describe other features thereof.

The object of the invention is a stackable tray for containing products. The technical problem to solve is to configure said tray to solve the problems of the state of the art and, therefore, to achieve a simple and more resistant tray than the known ones.

In view of the foregoing, the present invention relates to a tray that is formed from a cardboard sheet comprising a rectangular base on which the products are arranged, said base comprises two major sides, first and second, which in turn respectively configure a first and second bending line, two minor sides, first and second, which in turn respectively configure a third and fourth bending line, each major side is extended on a major, first and second side face , each minor side is extended on a smaller, first and second side face, thus configuring a tray of the usual and known in the prior art.

The tray is characterized by the fact that each major side, first and second side, presents both empty, first and second, third and fourth, on each side of a central, first and second elevation respectively; each of the two lateral sides of each major lateral face configures a bent, fifth and sixth, seventh and eighth line; for each of these lateral sides a portion is extended, first and second, third and fourth, which in turn is extended in an extension, first and second, third and fourth; between each portion and its corresponding extension a line of folded, ninth and tenth, eleventh and twelfth is configured; each major lateral face extends towards each central elevation and in its corresponding emptying in a tongue, first and second, third and fourth; between each major lateral face and its corresponding tongue, at least one line of bending, thirteenth and fourteenth, fifteenth and sixteenth is configured.

Once the tray thus described is formed, each major and minor side face is folded by its respective bending line and is oriented with respect to the base with an angle less than 90 ° with respect to it, thus forming a conical frustoconical configuration; on each side side of each major side face each portion is folded, first and second, third and fourth, to arrange each parallel and interior to its

corresponding minor side face; each of the extensions, first and second, third and fourth, is folded by its corresponding line of folded, ninth and tenth, eleventh and twelfth, so that each of them is angled with respect to each side greater and less than corresponds; each tongue, first and second, third and fourth, is folded by its corresponding bending line to be superimposed on its corresponding extension, thus forming a reinforced configuration at each corner.

An advantage is that the conical trunk is produced on all four sides of the tray, thereby overcoming the disadvantage of the state of the art that it could sink somewhere and crush the products.

Another advantage is that the structure of the tray is stronger than that of the known trays, especially because of the reinforced configuration of each corner and the intermediate support provided by each central elevation of each major side. Consequently, when the tray is supported by a panel, the transmission of the efforts to the pallet tables occurs at more points, so that the possibility of the tray being damaged or deformed, with the consequence of falling for the stack of trays located above and damage as a result of the products contained in each tray.

it may not be appreciated in figures 2 and 3, although it is represented, because they tend to be only a few degrees of inclination, in addition to the fact that the perspective of the figures can contribute to said lack of appreciation of the inclination; for each lateral side (1.74,1.75,1.84,1.85) of each major lateral face (1.7,1.8) each portion is folded, first (1.76) and second (1.77), third (1.86) and fourth (1.87), to be arranged each parallel and inner to its corresponding minor side face (1.9,1.10); each of the extensions, first (1.78) and second (1.79), third (1.88) and fourth (1.89), is folded by its corresponding bending line, ninth (1.781) and tenth (1.791), eleventh (1.881) and twelfth (1,891), so that each of them is angled with respect to each major (1.3.1.4) and minor (1.5.1.6) side that corresponds to it; each tongue, first (1,741) and second (1,751), third (1,841) and fourth (1,851), is folded by its corresponding bending line (1,742,1,752,1,842,1,852) to be superimposed on its corresponding extension (1,78, 1.79.1.88.1.89), thus conforming a reinforced configuration in each corner.

Figures 2 and 3 include most of the numerical references embodied in Figure 1, some remain to be included to make the figure clearer, being easily identifiable by reference to Figure 1.

A detail of the exposed embodiment, as shown in the figures, is that from each central elevation, first (1.73) and second (1.83), a flange, first (1,731) and second (1,831), is projected from each extension (1.78.1.79.1.88.1.89) a tab is projected superiorly, third (1,782), fourth (1,792), fifth (1,882) and sixth (1,892) respectively, the base (1.2) has perforations, first (1,71), second (1.22), third (1.23), fourth (1.24), fifth (1.25) and sixth (1.26) so that one tray stacked on another, figure 3, the first tab (1,731) is inserted into the first perforation (1.21 ), the second tab (1831) in the second perforation (1.22), the third tab (1.782) in the third perforation (1.23), the fourth tab (1.792) in the fourth perforation (1.24), the fifth tab (1.882) in the fifth perforation (1.25) and the sixth tab (1,892) in the sixth perforation (1.26).

Another detail of the invention is that the cardboard is of the corrugated type. This is how it is achieved

a certain stiffness of the tray (1). In particular, it is very advantageous that the main direction (D) of the corrugated wave is parallel to the smaller sides (1.5,1.6), as schematically represented in Figure 1. This gives a change in the usual sense of channel with what is achieved:

5 1) Increase the perimeter of cardboard in the direction of the wave and with it the capacity

of resistance

2 °) Increase the resistance to background flexion, since the direction of the wave at the base (1.2) of the tray (1) runs in the narrowest direction and a better distribution of the weight of the products on the surface, therefore, the possibility of bending decreases and the resistance to background bending increases.

Another detail of the exposed embodiment, as seen in the figures, and when the cardboard is of the corrugated type is that it is close and parallel to each thirteenth (1,742), fourteenth (1,752), fifteenth (1,842) and sixteenth (1,852) line Of 15 bending, a seventeenth (1,743), eighteenth (1,753), nineteenth (1,843) and twenty (1,853) bending line are respectively arranged to configure a double bending line. This facilitates folding, which is sometimes difficult due to the thickness of the corrugated cardboard.
