Abstract

1. Stackable box, of the type constituted from the development of a cardboard sheet with cut and fold lines to determine a central sector or bottom (1), two lateral sectors that form the major laterals (2) and two sectors determining ends of the heads (3), said heads (3) being provided with lateral extensions (4) that are partially attached to the interior of the larger sides of the box, said heads also having an end sector or bridge (7) upper with folding fins (8) for fixing to the lateral extensions (4), characterized in that the lateral extensions (4) have an inclined cut (5) on the lower edge thereof, and a stepped recess (6) in the upper edge, so that in the assembly of the box the heads (3) are slightly inclined inwards, while the upper edge of said extensions (4) and the bridge (7) are flush at the same height, defining a to The support surface for the box to be stacked superiorly, having provided that the bottom (1), in correspondence with the pointers, includes pairs of windows (9) for housing tabs (12) provided for this purpose at the upper edge of the pointers (3), said windows being slightly displaced inwards with respect to the fold line (11) between the bottom and the bottom, extending to said line through cut lines (10) which in the folding give rise to tabs (13 ) that protrude downward and define travel stops between boxes between their stacking.

OBJECT OF THE INVENTION

The present invention relates to a stackable box, of the type constituted in cardboard, intended for the transport and commercialization of fruit and vegetable products, box which presents 10 novel elements in relation to the means of stacking to increase the efficiency with regard to the stabilization of stacked boxes and their resistance when they are full of product

15 BACKGROUND OF THE INVENTION

Stackable cardboard boxes are known for fruit and vegetable products and the like, which are constituted from a rectangular sheet with cut and fold lines to form sectors that correspond to the bottom, the shelves and the slats, also having 20 extensions of the heads that are attached to the inner side of the sides and even with an extension of the testers themselves that in the assembly is horizontally in correspondence with said testers, forming a support surface for the box immediately superior and stacked with the previous one.

25 These types of boxes have the disadvantage that their stacking is not stable as a result of the absence of means that guarantee the immobilization of stacked boxes

DESCRIPTION OF THE INVENTION

30

The box that is recommended solves in a fully satisfactory way the problem described above, based on a simple but effective solution.

To do this, being of the type described in the previous section, it has the peculiarity 35 that the sectors or extensions that are derived laterally from the pockets have a

inclined cut that affects both the upper edge and the bottom of said sector, when the box is armed, allowing the bows themselves to be tilted into the box, while also allowing the upper horizontal section or bridge to remain parallel to the bottom of the box, thereby maintaining a larger support surface in the stacking between boxes

Another characteristic of novelty is that in correspondence with the fund and in close proximity to the treasures themselves, pairs of rectangular windows have been provided whose cut is out of phase with respect to the fold line between the bottom and the tester, determining that offset some small tabs that remain oriented down in the formation of the box and which constitute stop elements for the box when stacked on a lower one, thereby strengthening the system of immobilization in the stacking that is achieved by accommodation of upper tabs of the plug-in front windows fund referrals.

According to another of the features of the invention, the cut to make the windows at the bottom of the box has a semi-circular part that allows the die to make said window, giving greater area to the cutout and preventing the die from jamming when it should get out.

In this way a box with a double stacking system is obtained, formed by the classic crests of the pockets that are housed in windows made in the bottom and the bottom tabs of the bottom that stop against the pointers of the box on which it is Stack the previous one, and they are not completely vertical, but have a slight inclination inwards.

DESCRIPTION OF THE DRAWINGS

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

Figure 4 - Shows a detail in profile of the form of stacking between boxes, showing how the wall that forms each tester is tilted inwards and allows a more stable stacking between boxes

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, it can be seen how the box of the Invention is obtained from the development of a cardboard sheet with cut and fold lines that determine a central sector or bottom (1), two lateral sectors that form the sides major (2) and two determining extreme sectors of the heads (3), with the particularity that from the extreme sectors corresponding to the heads (3) side extensions (4) that have an inclined cut (5) at the edge are derived their lower part and a stepped recess (6) at the upper edge, so that the inclined cuts (5) allow the testers (3) to be slightly inclined inwards in the assembly of the box

The heads (3) are topped off in bridges (7) with extreme fins (8) that fold and are fixed to the extensions (4) through the stepped recesses (6), as can be seen clearly in figures 2 and 3, so that the upper edge of said extensions (4) and the bridge (7) are flush at the same height, defining a large support surface for the box to be stacked superiorly

At the bottom (1) and in correspondence with the testeros, pairs of windows (9) are provided slightly deeper than the fold line (11) between said bottom (1) and corresponding tester (3), so that tabs (12) are housed in said windows (9)

provided for that purpose at the upper edge of the heads (3).

The windows (9) extend to the fold line (11) by means of two cutting lines (10) which, when folded, give rise to tabs (13) that protrude downwards and which 5 define travel stops between boxes between their stacking , as shown in Figure 4, all in such a way that a double immobilization system is achieved in the stack, one corresponding to the tabs (12) housed in the windows (9) and the other by means of the stops defining the tabs ( 13) lower.

10 Finally, to say that the windows (9) have an internal semicircular sector (14) that facilitates the die-cutting operation, as regards the entry and exit of the die in the cardboard plate.
