Description

STACKABLE FOLDING BOX

5 OBJECT OF THE INVENTION

The present invention relates to a stackable folding box, materialized in a die-cut material such as cardboard, plastic or similar, in which fold and fold lines are established to allow both the unfolding or assembly of the box and the folding of the

10 same in a simple traction or compression operation.

BACKGROUND OF THE INVENTION

There are many types of folding boxes of cardboard or other similar materials, which are

15 obtained from the development of a cardboard sheet with cut and fold lines to define the bottom, side walls and even sometimes the lid, so that in any case the folding and unfolding is complex, especially in those boxes whose bottom It has a single-piece character, since the boxes whose bottom is formed by several superimposed pieces, the folding is easier and simpler, although it negatively affects the resistance of

20 said background.

Specifically, a type of box is known in which the fund is a single sector, which has appropriate bending lines to achieve the assembly and disassembly described in Spanish utility model 1,063,778, where the box presents, in correspondence 25 with the bottom, some diagonal fold lines, forming triangles that start at the confluence line of the sides with the bottom and are finished off in the intermediate fold line of the bottom itself, thus allowing folding through these triangular areas to achieve the folding of the bottom and with it the folding of the whole box, since the side walls that concur in said bottom are provided with fold lines that

30 continue the intermediate fold line of the fund.

This box, which is easy to assemble and disassemble, has the disadvantage that it has a rectangular prismatic configuration, which makes the stacking of it occupy a large volume in its assembly arrangement, which substantially limits said

35 stacking and use in this provision. -2

DESCRIPTION OF THE INVENTION

The box that is recommended, based on the folding system described in the utility model referred to above, solves in a completely satisfactory way the problem described above, based on a simple but effective solution.

For this, the box of the invention has the particularity that the configuration of the box once armed is inverted pyramidal trunk, which allows its stacking in said deployed position with a minimum volumetric occupation, impossible to achieve with the box described in the Spanish utility model 1,063,778.

More specifically, the box of the invention is obtained from the development of a sheet, with a central sector that will constitute the bottom, from which four lateral sectors that constitute the side walls emerge, so that two of said walls have an intermediate fold line that continues along the bottom, thus establishing a continuous fold line in which another plurality of fold lines concur that will form the triangular configurations that begin at the confluence between the fold lines of the side walls with that of the bottom.

On the other hand, the other two side walls, of trapecial configuration as well as the walls mentioned above, are continued laterally in extensions that will form a double wall or fixing tabs by means of adhesive or by any other conventional means, which they are superimposed on the side walls provided with the fold line, with both the walls and the affected extensions or tabs of windows being made to coincide in the assembly position of the box, establishing the appropriate manual grip windows of the box.

The trapecial configuration of the side walls, will allow stacking with a minimum volumetric occupation of the box with others of the same type when the box is armed, also allowing the folding and unfolding of it, easy and simple, in a single operation .

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 2.- Shows a perspective view of the box in an intermediate phase of folding it.

Figure 3.- Shows a perspective view of the box of the invention in its assembly position.

Figure 4.- Shows a view of the fully folded box.

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 in which a central sector (1) is established that will constitute the bottom, two sectors (2) opposite each other that will form two of the side walls, and two other sectors (3) also opposite each other and that will form the other two side walls of the box, so that it will have a square or rectangular bottom ( 1), two side walls (2) of trapecial configuration and two other side walls (3) of trapecial configuration. In the specific case of the embodiment shown in Figure 1, the two sectors (2) are smaller than the other two sectors (3), thus the sector (1) constituting the rectangular shaped bottom.

Continuing with the embodiment shown in Figure 1, it can be seen that the trapezoidal sectors (3) that are going to form the larger side walls of the box, are extended in

lateral extensions (4), which are superimposed in the armed position of the box, in pairs, to the sectors (2) constituting the minor side walls of the own box. In a preferred embodiment, the lateral extensions (4) are fixed to the sectors (2) by gluing. Obviously, so as not to interfere with folding and unfolding operations the length of the lateral extensions (4) will be less than half the width of the sectors (2), so as not to interfere with the fold line (6).

The sectors (2) and the extensions (4) are provided with two die cut (5) that they face each other in the armed position of the box and will form recesses determinants of the handles of the box.

The trapezoidal sectors (2) corresponding to the minor walls and the sector (1) of the background, are affected throughout its length of respective fold lines (6) and (7) respectively, aligned with each other.

On the other hand, and as can be seen in Figure 1, from the fold line that delimits the sector (1) of the fund with the sectors (2) constituting the minor side walls, split a plurality of diagonal and parallel fold lines (8) that concur in the own intermediate fold line (7) of the fund.

These diagonal and parallel fold lines (8) are arranged so that they form two groups of regular triangles of different sizes, the base of the groups being the base of the side walls of the box and its vertex being located in the line of weakening of the base of the box and having different heights.

In the exemplary embodiment shown in Figure 1, two groups of 5 are shown triangles, although the number of triangles, as well as the distance between them, will vary depending on the size of the box and the characteristics of the box material.

The objective of the fold line (7) of the bottom of the box and the fold lines diagonal and parallel (8) is that when the transverse walls fold towards inside (thanks to the fold line (6)), the bottom of the box, due to its fold line (7), can be folded at the same time, using the triangle-shaped folds,

as seen in figure 2.

It is therefore this specific configuration based on a plurality of triangles in the base that makes it possible to assemble and fold the box itself in a very simple way to

5 be folded on these diagonal lines (8), in combination with the folding of lines (6) and (7) that allow not only the folding of the bottom sector (1), on itself, but the folding of the sectors (2) corresponding to the smaller walls, folding them towards the inside of the box.

10 For the deployment, it will be enough to pull out the assembly and carry out the total deployment of a single maneuver of the body of the box, leaving it perfectly armed.

Once the boxes are assembled, thanks to the trapecial configuration of the side walls,

15 enables stacking with a minimum volumetric occupancy of the box with others of the same type.
