Description

Cardboard box for agricultural products.

Object of the invention

The present invention relates to a box of cardboard for agricultural products, specifically for products perishable and similar, being the box constituted with some features that allow a totally stable stacking between them, providing the fruit with optimal protection with a minimum development of the cardboard in which the box materializes.

It is therefore the object of the invention to provide a cardboard box, preferably corrugated cardboard, to contain perishable agricultural products, leaving these perfectly protected by virtue of the possibility of perfect stacking between boxes

Background of the invention

There are numerous types of boxes used for perishable products, from the classic boxes of plastic that are resistant and can be stacked together, to conventional cardboard boxes that are much more practices when it comes to manufacturing them and obviously much cheaper.

Well, the cardboard boxes capacity large suffer from the problem of offering minimal resistance in the stacking when the boxes are full of products, and this as consequence of still having prismatic reinforcements in the corners, however stacking stability is not the most adequate.

Description of the invention

The box that is recommended presents a series of particularities that, being of the type of remarkable capacity, allow stacking with others filled, in a completely stable position and with sufficient strength to admit several floors or rows of them, when they are full and without the risk that they may fall due to instability in the stack or that they may fall apart due to lack of resistance
same.

More specifically, the box of the invention, being of the type of those constituted from the development of a corrugated cardboard sheet with fold lines to form the background, some laterals and some pointers, presents the particularity that the testeros extend along their sides in paths rectangular flaps with a corresponding window precisely with a section of the fold line of those flaps lateral, there are two narrow ones at the same time  windows that affect approximately the upper half of the height of such pointers and outdated on either side of the imaginary intermediate line of each tester.

On the other hand, the major lateral ones present in their respective ends flaps, of rectangular configuration but with the bottom edge oblique and rising outward, already that these flaps affect part of the height corresponding to the upper area of the greater lateral commented, flaps than to its once they extend in rectangular tabs that after a double line bending ends in a small extension whose function is will expose later.

Finally, the testers mentioned first place have an extension on its longitudinal or upper edge of the same length as the testator itself although of lesser height, which has small extensions on its lateral edges, with the function and purpose set out below.

As commented, in the assembly of the box the front flaps are positioned vertically inwards and attached to the extreme sides of the sides older, while the flaps of those major laterals remain attached to the external part of the testeros and extensions rectangular of those flaps fold inwards posing as the narrow windows set in the testeros themselves, so that those rectangular extensions are fold inwards, attaching to the respective tester and retaining the small extreme extent of those extensions in the windows that make up the side flaps of the testeros.

Finally, the upper extensions of the testeros fold inwards, sticking to these and fixing the extreme extensions of those in them windows of the side flaps of the front doors where house extensions of extreme extensions corresponding to the flaps of the major sides.

This way you get a cardboard box wavy remarkably reinforced in its corners and in the heads, as well as externally protruding in those corners the parts corresponding to the ends of the sides and the part upper flaps of those sides, determining internally to those angular corners some supports by the extreme edges of the pockets and the flaps themselves sides of these, which allow optimal stable stacking between boxes, as a consequence in addition to the configuration of the box is slightly inverted trunk-pyramid for facilitate the fitting in the stack and therefore get a optimal stability in said stack.

As is evident, the box may be equipped with holes for aeration of the products it may contain, as well as some recesses on the major sides and certain others in the heads, as a result of the angular corners that protrude from the upper edge of such heads, and thereby allow optimal aeration of the contents of the box.

Description of the drawings

To complement the description that then it will be done and in order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof, is accompanied as an integral part of that description, a set of drawings in where illustrative and not limiting, it has been represented the next:

Preferred Embodiment of the Invention

In view of the commented figures, you can observe how the box of the invention is constituted from a corrugated cardboard sheet on which a part is established rectangular and central (1) that will constitute the bottom, lateral ones older (2) and some testers (3), all as conventional, and where the lateral ones (2) and testeros (3) are delimited with respect to the fund (1) through corresponding lines of fold (4 and 5), respectively.

One of the features presented by the box of the invention is that the heads (3) are prolonged by their lateral ends in rectangular flaps (6) affected by a window (7) in correspondence with the fold line (8) that delimit each flap (6) with respect to the side of the tester (3), as is clearly seen in figure 1.

The testeros (3), in addition to those flaps (6), they have longitudinal extensions (9) whose edges laterals have very narrow extensions (10), provided in addition that the testeros (3) have a close couple windows (11) that affect approximately half the height of those heads (3) in the assembly of the box.

On the other hand, the sides (2) are extended by its ends in flaps (12) that do not affect all of the height of those sides (2), and whose flaps (12) have their lower edge (13) oblique, extending such flaps (12), without affect all its external amplitude, in extensions (14) than its Once they have a small projection (15) on their outer edge.

The flaps (12) are delimited with respect to the sides (2) by means of the corresponding fold line, while between these flaps (12) and the extensions (14) there are a fold line.

In accordance with these characteristics, and from of the development shown in figure 1, the assembly of the box is as follows:

Firstly, the roofs (3) are raised to place them at 90 ° from the bottom (1), through the line of corresponding fold (5), folding in turn the flaps (6) inward, that is, disposing at 90 ° from the plane of the heads (3), as clearly represented in the figure 2.

From this folding phase, we proceed to lifting of the sides (2), standing equally perpendicular to the bottom (1), leaving the flaps (6) of the testeros (3) attached to the inner side of those sides (2), while the flaps (12) of those sides (2) are attached on the external surface of the testeros themselves (3), and protruding from the fold line (16) that delimits each tester (3) of its corresponding extreme and superior extension (9), as can be clearly seen in Figure 3.

In turn, the extension (14) of the flaps (12) it is passed through the narrow window (11) of the heads (3), as depicted in Figure 3, to be carried out later the folding of these extensions (14) on the inner face of the own testeros (3), joining these and housing the protrusions (15) of such extensions (14) in the windows (7) of the flaps (6), as depicted in Figure 4.

Once that armed phase is finished, subtract only by folding inward the extreme extensions and higher (9) of the testeros (3) through the double line of folded (16), leaving that extension (9) in each case in correspondence with the internal part of the testeros (3), determining a reinforcement of these and a wide support located by below the edge that define the angular corners (19) established by the upper part of the flaps (12) and by the upper part of the ends (18) of the sides (2).

The fastening of the extensions (9) is carried out by housing the lateral and external projections (10) of those extensions (9) in the same windows (7) of the flaps (6) of the heads (3), in whose windows (7), as already You said before, the extensions are hosted (15) corresponding to the extensions (14).

The box can be complemented with corresponding openings (20) of the driving poles appropriate, as well as with holes in the bottom and even in the side and front, and recesses on those sides, as shown clearly in the figures.

The box thus constituted presents a slightly trunk-pyramidal conformation inverted, which makes possible an easy and stable stacking between full boxes, since the corners of the bottom will be positioned in the internal corners (19) corresponding to the protruding parts upper box immediately lower, supporting the upper in the double folds (16) of the heads, offering the structuring the box enough strength to withstand several boxes full and stacked together.
