Description

Stackable box.

Object of the invention

The present invention relates to a box, of type of those obtained by a single piece body obtained by injection based on plastic material and commonly used to transport fruit and vegetable products, between Many others.

The object of the invention is to get a box that can be stacked with identical ones in loading situation, and that however, it can be fitted in a vacuum, to drastically reduce its volumetric occupation in such circumstances, both from the point of view of storage as of transport.

Background of the invention

In the field of plastic boxes previously mentioned there are basically two types, one in which The box is of prismatic-rectangular configuration, so that it allows stacking with other identical boxes to considerable heights, determined by its own rigidity structural, and another in which the boxes adopt a configuration pyramidal trunk, divergent towards its mouth, boxes that in turn allow to fit in empty with other identical ones.

The problem inherent in the first type of box quoted, as is obvious, focuses on the fact that the occupation volumetric of the boxes is practically the same in vacuum as in load, which is a major problem both when store how to transport said boxes in such a situation of empty.

On the other hand the boxes of the second type, although satisfactorily solve the problem mentioned above that can be stacked in a vacuum drastically reducing their occupancy volumetric, in turn presents as a problem the impossibility of direct stacking between them, stacking that is just feasible using auxiliary means such as establishment of platforms on the boxes that constitute the support base for the upper boxes.

Description of the invention

The box that the invention proposes groups the advantages of the two groups of boxes mentioned above eliminating its inconveniences, that is, it is a box which is perfectly stackable in load situation and without however it allows to be fitted in another identical one in situation of empty.

To do this and more specifically said box presents a body of conical and inverted configuration, of divergence towards its mouth, necessary configuration for allow its encajable character, but with the special particularity that in correspondence with the extremes of one of its gates and with the opposite end of each of its heads, it incorporates windows, elongated vertically, in correspondence with which and at the level of its external face incorporates two blocks binoculars, which affect a lower end sector and that have with extensions also lower, so that two boxes can be stacked because the tacos of one of them are they slide down the windows of the immediately lower when tacos and windows are operatively faced.

However if the position of the upper case changes with respect to the lower one, specifically with a turn of 180º, dowels and windows become rampant, so that the upper box rests on the mouth of the lower one, in perfectly stable position because the box incorporates level of its mouth grooves for tongue and groove coupling of the extensions of the tacos mentioned above and that remain faced with such extensions in such relative position between boxes

According to another of the characteristics of the invention said windows have a trapezoidal front very stylized isoscells, divergent upwards, to facilitate self-centered engagement between boxes, having planned a similar configuration in those cited extensions, to also facilitate their penetration into complementary slots.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows, according to an overview in perspective, a stackable box, performed in accordance with the object of the present invention.

Figure 2.- Shows another perspective view of the same box, as opposed to that of the previous figure.

Figure 3.- Shows, finally, a view in side elevation of the same box.

Preferred Embodiment of the Invention

In the figures outlined, a conventional plastic box with trellised walls and bottom for minimize the weight and amount of material participating in the same, but obviously it can be a wall box closed, as long as your body (1) adopts a configuration pyramidal trunk, rectangular, divergent towards its mouth, to allow fitting between boxes.

Well, according to the invention, the box is provided, at the ends of one of its shelves (1), of a pair of vertical windows (2), in extreme positions, windows that extend superiorly in an internal groove (3) that extends to the mouth of the box and that are topped by its lower limb in studs (4), projected outward, so that its outer face is placed in the imaginary plane vertical through the mouth of the box.

In addition, two others are established windows (5), identical to the previous ones, in correspondence with the end of each tester (6) opposite the rack (1) that incorporates the windows (2).

This allows, as previously stated, that the blocks (4) of a box penetrate through the grooves (3) and the windows (2) and (5) of another box until a situation fitting limit at which the perimeter reinforcement of the mouth of each support box on the one of the immediately lower.

Each block has a lower extension (7), collaborating with these extensions (7) slots (8) operationally established on the upper edge of the other gualdera (9), at the ends of it, and on each of the testeros (6) as opposed to sales (2).

This way when a box is placed on another in 180º rotated position, the studs (4) of one of them remain off the inside grooves (3) and the complementary windows (2) of each other, so that you cannot the engagement occurs, stabilizing the stack by introduction of the mentioned extensions (7) in the complementary grooves (8).

It only remains to point out finally that the tacos (4) they extend with a single piece character in side partitions (10), that extend to the perimeter reinforcement of the mouth of the box, so that the stacking support is produced through the lower limb (11) of said partitions, in a situation where extensions (7) they are housed in the grooves (8) to stabilize the stack crosswise.

As seen especially in Figure 3, the windows (2) and consequently the partitions (10), are divergent towards the mouth of the box, to facilitate the self-centering between boxes in the fitting of the same.

Claims (4)
