STORAGE BOX

Abstract

A storage box includes a single sheet of material that, when folded to define the storage box comprises a bottom, side walls, and a flap hinged to one of the side walls. The flap includes a stacking tab that is movable between a use position in which the stacking tab protrudes through a mounting slot and a hidden position in which the stacking tab does not protrude from the storage box. The storage box allows the stacking tabs to be used only when necessary and not protruding from the storage box when not in use.

DETAILED DESCRIPTION

[0031] Firstly, it is indicated that the box according to the present disclosure is formed from a single sheet of material, preferably a corrugated material, such as corrugated cardboard, defining a plurality of channels substantially parallel to each other.

[0032] The box of the present disclosure may be used for storage of products, i.e., it requires strength characteristics to prevent the products from being damaged during the use of the box, which is also stackable.

[0033] A first example implementation of the box according to the present disclosure is shown in FIGS. 1 to 3.

[0034] According to this first example, the box is formed from a corrugated cardboard sheet that, in its mounting position, defines side walls 1 and a bottom 2. In the shown example, the side walls 1 are three, and an upper part or wall 9 is also present, so that a front opening is defined for access to the box, which means that the box is filled laterally.

[0035] In this position of use shown in the figures, the corrugated cardboard channels are arranged vertically or inclined, to provide adequate resistance to stacking.

[0036] According to this example, two flaps 4 extend from two opposite side walls 1, which in the position of use are placed on the internal part of the side walls 1, as can be seen in FIG. 3. Each flap 4 is hinged to the respective side wall 1 about a folding line 8.

[0037] Furthermore, these flaps 4 also comprise reinforcing tabs 10, which are placed in contact with the other side wall 1 to reinforce the resistance to stacking. These reinforcing tabs 10 comprise projections 11 that keep each flap 4 slightly separated from, and substantially parallel to, the corresponding side wall 1.

[0038] Each of these flaps 4 further comprises a stacking tab or flange 3, which is hinged with respect to the flap 4, and which can be placed in a position of use or in a hidden position, as will be explained below.

[0039] As previously mentioned, it is precisely in the space between the flap 4 and the side wall 1 where the stacking tabs 3 are housed in their position of use; both those of the box itself and those of the same or compatible box that is stacked with the first one. The stacking tabs 3 of a box are housed in the space between the two surfaces of another similar or compatible box when inserted through stacking slots 5.2 conveniently located at the bottom of the box.

[0040] This stacking tab 3 is preferably arranged in a middle position near the top of the flap, according to the shown position of use, and it is hinged with respect to a substantially horizontal folding line, so that it can be placed in a position substantially vertical downwardly (FIG. 3, upper box) or in a substantially vertical upwardly position (FIG. 3, lower box).

[0041] In FIG. 2 it can be seen how the stacking tab 3 is placed in its upright position, or use position, protruding through a mounting slot 5 located in the upper part or wall 9 next to the upper edge of the corresponding side wall 1.

[0042] In order to place the stacking tab 3 in its position of use, firstly, the flaps 4 are folded into the box, and then the stacking tabs 3 are folded upwardly, entering the mounting slots 5.

[0043] In FIG. 3 two boxes are disclosed according to this first example are shown. The upper box is with the stacking tabs 3 in their hidden position, while the stacking tabs 3 are in their use position, allowing the upper box to be stacked using the stacking slots 5.2.

[0044] In FIGS. 4 to 8, a second example of the box according to the present disclosure is shown.

[0045] For simplicity and clarity reasons, the same reference numbers are used to identify the same components of the box that were used in the previous example. In addition, only the differences with respect to the first example previously disclosed are described for the sake of simplicity.

[0046] The main difference of this second example is the position of the stacking tabs 3, which are arranged at the end of the flaps 4, and are oriented downwardly, so that in their position of use they protrude from the lower portion of the box.

[0047] As can be seen in FIG. 4, the flaps 4 have a shape defined by two portions, a proximal portion that is extended in a hinged way from the folding line 8, the in this example is inclined, of the front of the box, and a distal portion provided with the stacking tab 3 at its end.

[0048] The stacking tab 3 forms a cut-out area 7, defining a projection 6, which is housed in the mounting slot 5 of the box in the hidden position of the stacking tab 3, as will be described below. In this example, the mounting slot 5 is located at the bottom 2.

[0049] The box of this second example also comprises a frontal flap 12 provided with a longitudinal folding line 13 that divides it in two, so that, in its use position, it forms a double-thickness front wall, as shown in FIG. 8, with reinforcing plates 16. For fastening, this frontal flap 12 comprises projections 14 that are housed in complementary slots 15 arranged on the frontal edge of the bottom 2.

[0050] For the placement of the stacking tabs 3 in their position of use, the flaps 4 are folded towards the inside of the box (FIG. 5), the stacking tabs 3 being inserted in the mounting slots 5 in the side edges of the bottom 2 of the box (FIG. 6), the stacking tabs 3 protruding on the lower portion for their coupling with a lower box, with is the same as the first one or compatible with the first one, which has corresponding stacking slots 5.2 located on the side edges of the upper part or wall 9.

[0051] For the placement of the stacking tabs 3 in their hidden position, the flaps 4 are also folded towards the inside of the box (FIG. 5), the projections 6 being inserted in the mounting slots 5 in the side edges of the bottom 2 of the box (FIG. 7), locking the flaps 4 in their position substantially in contact with, i.e., substantially parallel to, the side walls 1.

[0052] In FIG. 8, two boxes according to this second example are shown, with the stacking tabs 3 in their use position in the upper box and in their hidden position in the lower box.

[0053] In FIGS. 9 and 10, a third example of the box according to the present disclosure is shown.

[0054] For simplicity and clarity reasons, the same reference numbers are used to identify the same components of the box that were used in the previous examples. In addition, only the differences with respect to the first example previously disclosed are described for the sake of simplicity.

[0055] The main difference of this third example with respect to the first example is that the flaps 4 are hinged from a middle portion of the side wall 1, the stacking tabs 3 being arranged at the end of the flaps 4.

[0056] To place the stacking tab 3 in its position of use, firstly, the flaps 4 are folded upwardly, as shown in the detail of FIG. 10, and then the stacking tabs 3 are folded upwardly, being inserted inside the mounting slots 5.

[0057] Although reference has been made to specific examples, it is apparent to a person skilled in the art that the described storage box is susceptible of numerous variations and modifications, and that all the details mentioned can be replaced by other technically equivalents, without departing from the scope of protection defined by the appended claims.
