Description

DESCRIPTION

Self-assembly box

TECHNICAL SECTOR

The present invention refers to a self-assembling box, that is to say, to a box that from a single-piece die-cut cardboard laminar body is capable of being transformed into a rectangular prismatic box, open at the top, without the need for any type of additional accessory. , such as adhesives, staples or the like.

The object of the invention is to provide a box that is easy to assemble, inexpensive, with a minimum volumetric occupation in an inoperative situation, and stable once assembled.

BACKGROUND OF THE INVENTION

In the field of practical application of the invention that of prismatic-rectangular boxes open at the top, as trays, this type of packaging is usually obtained from the development of a die-cut cardboard sheet in which a rectangular bottom is defined, from which, from the fold lines, emerge the headboards and gutters, which are linked together through lateral tabs that must be fixed to the corresponding gualdera or headboard by means of gluing, staples, or the like.

This operation complicates the assembly of the boxes, especially if they do not want to assemble until the moments prior to their use to minimize their storage space.

Although some containers are known that present a configuration in which their assembly is possible without the need for fixing elements such as adhesives or staples, this type of containers present a complex or unstable structure once assembled, in addition to being capable of causing potential jams when armed automatically through automated machinery systems.

EXPLANATION OF THE INVENTION

The self-assembling box that is advocated solves in a fully satisfactory way the problems previously exposed, based on a simple but effective solution.

For this, and more specifically, the box of the invention is constituted from the development of a sheet of die-cut cardboard, in which a rectangular central sector is defined, from whose larger sides two rectangular sectors that determine the flanges emerge, while that from its smaller sides emerge two trapezoidal-lysoscelic sectors whose major base coincides with the minor lateral edge of the bottom of the box, and whose minor base extends into an inverted isoscelic trapezoidal sector whose major base is of less amplitude than the major base of the main sector from which it emerges.

On the other hand, from the sides of the gualderas emerge two straight trapezoidal sectors that are linked to the central sector previously described through inverted triangular sectors whose lateral edges of connection to these sectors define folding lines for the formation of the end caps.

In this way, when folding the gualderas inwards, said maneuver will cause the displacement and folding of both the straight trapezoidal sectors and the intermediate isoscelic trapezoidal sector, due to the triangular configuration of the sectors that link these elements together, so that in a situation of armed, these are partially overlapped in the vertical plane.

To stabilize the set formed by these three elements, it has been foreseen that the straight trapezoidal sectors present a stepped recess in correspondence with their side perpendicular to their bases, in correspondence with the end of the smaller base that, together with the opposite straight trapezoidal sector, define a "U" -shaped notch into which a stamped flange fits over the upper middle area of the central sector that folds over this notch, and which also has a slightly greater width, which significantly improves stability during assembly.

From this simple maneuver it is possible to assemble the box in a minimum time and without the need for any type of accessory element such as staples or adhesives, so that it can be stored disassembled and with a minimum volumetric occupation stacked with others of the same type until its services are required, thus optimizing the available space.

In any case, the described box can be easily assembled either manually or by means of specialized machinery, without the risk of jams in said assembly process.

Finally, it only remains to point out that the three sectors that determine the ends of the box in the assembly will all have a determining notch of a manual grip handle of the box, which in the assembly will be properly facing each other, determining a single handle , preferably arched configuration, since this configuration increases the resistance to breakage in front of straight handles or with upper cleft.

To complement the description that is going to be made below and with the aim of helping a better understanding of the characteristics of the invention, according to a preferred example of a practical embodiment thereof, a set of drawings is attached as an integral part of said description. where, with an illustrative and non-limiting nature, the following has been represented:

Figure 2.- Shows a perspective detail of the box in an initial assembly phase for it.

Figure 3.- Shows a view similar to that of figure 2, but in a later assembly phase.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the outlined figures, it can be seen how the box of the invention is constituted from the development of a die-cut cardboard sheet, in which a rectangular central sector determining the bottom (1) is defined, from whose larger sides each emerge rectangular sectors determining the gualderas (2), while from their smaller sides emerge two trapezoidal-isoscelic sectors (3) whose larger base coincides with the smaller lateral edge of the bottom of the box, and whose smaller base extends into a trapezoidal sector Inverted isoscelic (4) whose major base is smaller in amplitude than the major base of the main sector from which it emerges.

As can be seen in figure 1, two straight trapezoidal sectors (5) emerge from the sides of the gualderas (2) that are linked to the trapezoidal-isoscelic sector (3) through two inverted triangular sectors (6) whose lateral edges (7) define folding lines for the formation of the end caps.

From this structuring, and as can be seen in Figures 2 and 3, in the maneuver of folding the flaps (2) towards the inside of the box, the displacement of said flaps forces the trapezoidal sectors straight lines (5) fold towards the inside of the box, which in turn causes the inverted triangular sectors (6) to fold, pulling the straight trapezoidal sector (5), which will be partially superimposed on these elements, such as Figures 3 and 4 show, thus forming the corresponding headboard.

As previously pointed out, to stabilize this set it has been foreseen that the straight trapezoidal sectors (5) include a stepped recess (8) in correspondence with the side perpendicular to their bases, in correspondence with the end of the smaller base. which, together with the stepped recess (8), the opposite straight trapezoidal sector (5) define a "U" notch into which a flange (9) punched over the upper middle area of the central sector that participates in the end wall fits folded over this notch, as shown in figure 3, flange (9) that extends laterally in two end sectors that make it have a width slightly greater than the "U" notch formed by the stepped recesses (8), which significantly improves the stability in the assembly.

To facilitate the grip of the box, it has been foreseen that the three sectors that in the reinforcement determine the ends, that is to say both the straight trapezoidal sectors (5) and the trapezoidal-isoscelic sector (3) include a determining arched notch (10) of a manual grip handle of the box, which when assembled will be properly facing each other, determining a single handle for each head.

It only remains to point out finally that, to facilitate the folding maneuvers of the sides of the inverted triangular sectors (6), these can include elongated slots (11) that extend slightly from the lower vertex along one of the sides. of said triangle.
