Description

DESCRIPTION

Packaging corner

TECHNIQUE SECTOR

The present invention refers to a corner piece for packaging, which is intended to replace the classic polystyrene corner pieces with a device made exclusively of cardboard, resulting in a significantly more ecological, economical product with a lower volumetric occupation in a storage situation.

BACKGROUND OF THE INVENTION

In the scope of practical application of the invention, that of packaging certain products such as radiators, appliances or other delicate products, corner pieces based on expanded polystyrene are used that adapt to the edges of the product to be packed in order to protect it against to possible shocks during transport or handling.

Although these types of devices fulfill the function for which they were designed, they pose an environmental problem by virtue of their very nature and that they are plastic elements that will be discarded once the packaging is opened.

They also pose an economic problem when changing the smallest detail of the configuration of the product to be packaged, since a completely new mold will be required to adapt to the new specifications.

Although corners are known in which cardboard is used, they are complex and expensive structures, such as for example based on cardboard sheets with a honeycomb structure, the cost of which is very high, and they have a very significant volumetric occupation. which would be desirable to minimize.

There are also cardboard corners that must be assembled by hand and do not allow the process to be automated, which entails high operating costs, especially in personnel.

EXPLANATION OF THE INVENTION

The corner piece that the invention proposes completely satisfactorily solves the problem previously explained, based on a simple but extremely effective solution.

To this end, the corner guard of the invention is made from three die-cut laminar pieces of cardboard that give the device a minimum cost without compromising its impact protection performance.

More specifically, the three pieces of cardboard are intended to constitute three bodies in the form of boxes open at the top whose perimeter decreases so that some are fitted into others, finally obtaining a body in the shape of a corner piece with a triple wall with a thickness enough to protect the objects on which the corner piece is applied against impacts, in a similar way to polystyrene corner pieces, but with much greater customization possibilities and at a lower cost.

The first of the boxes, the one intended to define the outer surface of the corner, will be made up of a laminar body of die-cut cardboard, in which a rectangular base is defined, from whose larger side edges emerge two determining sectors of the side walls. larger, while determining sectors of the smaller lateral walls emerge from their smaller lateral edges, which are fixed to the larger lateral walls through sectors that are lateral extensions of one or other lateral walls.

An intermediate box fits tightly within this first outer box, which has a configuration similar to that of the outer box, but with slightly smaller dimensions, a reduction in dimensions according to the thickness of the cardboard sheet from which the first is obtained. box, so that this intermediate box does not require the fixing sectors between the larger and smaller side walls, as said walls are held by the outer box itself in which it fits.

Finally, the third inner box is constituted from a laminar body of die-cut cardboard in which a main rectangular sector is defined with dimensions in accordance with the internal contour of the base or bottom of the intermediate box, and which includes two sectors that, Depending on the chosen embodiment, they can emerge either from the larger lateral edges of the bottom or from the smaller lateral edges of said bottom, defining in one case two larger side walls that adapt laterally to the larger side walls of the intermediate box. , or two smaller side walls that adapt laterally to the smaller side walls of the intermediate box.

During assembly, all the side walls of the three boxes are flush, forming a corner with a structure based on three cardboard walls, sufficient to absorb the impacts that the packaged products may receive.

In accordance with one of the essential characteristics of the invention, based on this structure, the corner piece can include other die-cuts that are easily adaptable depending on the products to be protected, with a minimum manufacturing cost, such as die-cuts for cable attachment. , to define spaces for cases with screws or small complementary parts of the packaged device, etc.

Furthermore, this structuring allows the corner piece to be assembled by a machine, although it can also be assembled manually, with its three pieces having a flat initial configuration, which means that the product occupies a minimum volume in storage, as it is easily stackable.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, it can be seen how the corner piece of the invention is made from three die-cut laminar pieces of cardboard intended to form three bodies that fit together, as three boxes, an outer box (1), an intermediate box (2) and an internal box (3).

The outer box (1) is constituted from a laminar cardboard body in which an elongated rectangular central sector determining the bottom (11) is defined, from whose larger side edges emerge separate sectors determining the larger side walls (12). , while determining sectors of the smaller side walls (13) emerge from its smaller lateral edges, which are fixed to the larger side walls through lateral sectors (14-14') that in the example embodiment of Figures 1 to 4 and 6, are extensions of the smaller side walls (13), but, as shown in the example embodiment of Figure 5, said joining sectors could also emerge from the larger side walls, being fixed by gluing to the smaller side walls, without affecting the essence of the invention.

In any case, an intermediate box (2) fits tightly within the outer box (1), based on a die-cut laminar body, in which an elongated rectangular central sector determining the bottom (21) is defined. from whose smaller lateral edges separate determining sectors of the larger lateral walls emerge (22), while determining sectors of the smaller lateral walls emerge from its smaller lateral edges (23).

This piece will have dimensions slightly smaller than the outer box, according to the thickness of the latter, so that they fit snugly and their mouths are properly flush with the assembly, as shown in Figure 4.

Finally, the third piece is constituted from a laminar body of die-cut cardboard in which a main elongated rectangular sector determining the bottom (31) is defined, with dimensions in accordance with the internal contour of the base or bottom of the intermediate box ( 2), and which includes two lateral sectors that adapt to the side walls of the intermediate box (2).

In the embodiment variant of Figures 1 to 4, as well as in the second embodiment variant shown in Figure 6, these lateral sectors emerge from the smaller lateral edges of the bottom (31), defining smaller side walls (32), while that in the variant embodiment of Figure 5, these sectors emerge from the larger side edges of the bottom (31), defining larger side walls (32') that adapt internally to the larger side walls (22) of the intermediate box ( 2).

In any of the three embodiments, an economical corner piece is obtained, with a three-layer structure that defines a means of protection for the product to be packaged.

As mentioned above, one of the essential characteristics of the invention is that the device thus described can be easily customized to adapt to different requirements, such as the inclusion of spaces for bags of screws or small parts, which could be obtained by die-cut base (15-24-33), or for cable passage, such as the slots (16-25-34), provided on the larger or smaller side walls according to the specific requirements of each case, giving great versatility to the product . These die-cuts (15-24-33) and/or slots (16-25-34) are configured so that when assembled with the three boxes they are located in correspondence, thus generating the desired gap or space or the slots for the passage of cables or tying straps through the three boxes (1,2 and 3).

It only remains to be noted finally that the level of automation offered by the corner plate of the invention is variable, depending on the cost that is to be assumed in the assembly machines.

Thus, the formation of the outer box (1) of the packaging could be exclusively automated, so that the two inner boxes are inserted manually by an operator, or the insertion of the intermediate box (2) inside the box could be additionally automated. external or even automate the entire process so that the three boxes (1,2,3) are assembled automatically by a machine.
