DESCRIPTION

OCTOGONAL CASE OF AUTOMATIC FUND

OBJECT OF THE INVENTION

The box of the present invention is a high performance packaging solution for the transport and storage of bulky material, such as granulated, powdered products, etc. The case of the present invention is based on a tubular structure of the prismatic-octagonal type that is inserted into a bottom formed in a novel way by two equal elements, which when superimposed crosswise with an element allow the bottom to be blocked by means of counter pressure.

BACKGROUND OF THE INVENTION

The boxes made of corrugated cardboard and / or composite materials, are widely used in the fruit and vegetable sector and in other non-food sectors but suffer from a series of related problems, in general, with the fact that the process of Production requires considerable quantities of raw material with large quantities of cardboard that is discarded as waste in order to produce reinforced corners, especially on the sides of the smaller sides or the faces of the larger sides of the box.

This often leads to the manufacture of boxes without horizontal or lateral support elements, known in the sector as "pavements", or to the manufacture of boxes with side edges with a uniform height in order to avoid a considerable cost of cardboard and / or other composite materials.

Another drawback is that a box made of cardboard and / or composite materials is often supplied as a flat die which is difficult to assemble.

For the same reasons, cardboard boxes and / or composite material of the known type that are already assembled are difficult to deploy and return to their flat state necessary to facilitate storage in the preparation for reuse or for recycling or recycling operations. destruction prior to disposal as waste.

French patent document FR-A-2236738 discloses a one-piece cardboard box formed from a matrix having a bottom panel, side and end wall panels, corner connector panels intersecting edges of which are attached, respectively, to a side and end wall panel, a locking panel attached to at least one of the connector panels at each end of the cardboard box and, optionally, one or more top panels. The connector panels have a diagonal fold line that divides the panel into a first triangular reinforcement section fixed to an end wall panel and a second triangular reinforcement section fixed to a side wall panel. The locking panel is attached to the second triangular section of the connector panel. In the cardboard assembly box, the triangular sections of each connector panel are folded in front contact and arranged outside the end wall panel with the first triangular section sandwiched between the end wall panel and the second triangular section. The locking panel extends over the upper edge of the first triangular section and the end wall panel inside the cardboard box where it is fixed in front contact with the inner surface of the end wall panel to maintain the box cardboard in the mounted position.

The utility model application U201500584 reveals a box that presents an octagonal prismatic configuration with two major faces, two smaller faces, alternated with the previous ones and four other faces of smaller amplitude, forming what can be considered as four chamfers between the faces minor and major faces. From this octagonal contour, the box presents, in correspondence with one of its edges, cut and fold lines that allow the bottom to be formed, since the box in question is intended to be arranged on a pallet or a surface that it will act as part of the bottom of it, presenting in that fund two major lateral wings, and two other minor ones, the latter with an intermediate and central cutting line that derives in two oblique cutting lines, forming a trapecial contour of reinforcement of the The fund itself, while the major extensions mentioned above, have oblique fold lines, forming triangles that remain, in one case attached to the inner side of the smaller sectors, and in another case by the outer face of these. The box is obtained from the development of a rectangular cardboard sheet with transverse fold lines to delimit sectors that will form eight faces that define the lateral surface of the box, presenting an octagonal contour, defining two sectors (1) or larger walls, two sectors or intermediate walls (2) alternated with the previous ones, and between both sectors (1) AND (2) four smaller sectors (3) determining chamfers that make up the octagonal outline of the box itself bliss

The utility model application U200900797 starts from the conventional octavines, specifically two octavines and consists of the incorporation into the box of a tubular, prismatic-octagonal body, which is plugged by its lower extremity into the lower octavin which closes analogously by its upper extremity with the collaboration of the second octavín, in cover functions. The bottom of this box is formed by a piece of cardboard which has a plurality of cuts that form flaps and that when folded vertically allow to generate a cavity where the prismatic-octagonal tubular body is inserted. One of the problems generated by this type of box is that a large amount of material is lost in the manufacture of the fund due to the cuts made in the structure that gives rise to the fund, in addition to the fact that each time it is transported it is necessary to reassemble The whole structure.

The box of the present invention presents the novelty that its bottom is formed by two equal elements that when superimposed in a cross-shaped way allow the bottom to be blocked by means of counter pressure. When the two similar structures cross overlap, the sides allow them to be folded down, strengthening the bottom and avoiding that when introducing the belt-like structure, it folds back on itself obtaining a high-strength box, which does not require additional elements to achieve withstand the lateral forces to which its walls are subjected when loading products such as melons, potatoes, etc., regardless of the self-assembly process of the box in question, so that a box that is reinforced is obtained to reduce lateral buckling or bending caused by the contained product, thus solving the problems and inconveniences that conventional boxes of this type present.

The box can be easily transported, since the bottom can be folded over the center of the bottom causing the entire structure to fold inwards, so it is not necessary to assemble the entire structure every time it is transported, as it would be enough to deploy again the box through the center of the bottom (50) when required thus obtaining the box, thus the box when storing and transporting occupies the smallest possible space.

The box of the present invention is a high performance packaging solution for the transport and storage of bulky material, such as granulated, powdered or loose products, the box is made of high performance corrugated cardboard and can be mounted manually It is also a cost-effective and ecological alternative to wooden or metal drawers. The lightweight but high performance material decreases the weight of the load, reducing costs.

DESCRIPTION OF THE INVENTION

The box of the present invention is a high-performance packaging solution for the transport and storage of bulky material, in addition it does not require additional elements to be able to withstand the lateral forces to which its walls are subjected when loading products such as , melons, potatoes, etc.

The bottom of the box is formed from two identical semi-bar-shaped elements (1) and they are glued in two places on the outer perimeter of the octagonal central body with the help of flaps. Each of these components is equipped with a bellows system that allows the interior to fold back in order to limit the space. The cross-assembly of these 2 elements makes it possible to guarantee the assembly and the maintenance of the bottom by a counter pressure system.

When the two similar elements (1) cross overlap, the sides (7) allow them to be folded down, strengthening the bottom and preventing the central body (2) from entering, which retracts on itself. This set allows the user When deploying the belt, automatically form the bottom without additional component.

PREFERRED EMBODIMENT OF THE INVENTION

The box of the present embodiment is formed from the union of two equal elements (1) that form the bottom and have the shape as seen in Figure 1 and the insertion of a central body (2) in a prismatic manner. octagonal that is inserted in the result of cross-overlapping the element (1) with a similar one. The elements (1) that form the bottom thanks to the angle between the flap (10) and the flap (20) allow them to fold inwards on the fold lines (3) and (4). Each element (1) that allows to form the bottom of the box has in the coupling area, the intersection of two curved ends (8) and (9) whose elliptic curve shape allows the element (8) to be mounted on the element (9) at point (60) and therefore when coupled with another element (1) they are fixed in a resistant manner when forming the bottom of the box.

The flaps (30) and (40) are equal symmetrical images with respect to an axis that passes through the junction point between the flaps (10) and (20) and folds inwards on the lines (5) and (6) . When the flaps are folded up through the folding lines (3), (4), (5) and (6) forming 90 degree angles with respect to the lower plane, 4 adjacent vertical planes formed by means of the flaps (10), (20), (30) and (40) the height of these vertical planes being the same dimensions as the width of said flaps. The junction point of the end sides (8) and (9) produce a central point (50) that when superimposed crosswise with a second element (1) allows the bottom of the box to be formed, since it is blocked by means against pressure. By superimposing on The two similar elements (1) cross, the sides (7) and (7 ') allow to be folded down, strengthening the bottom and avoiding that when the central body (2) is introduced, it retracts on itself.

The central body (2) is formed from a cardboard sheet originally opened and folded in the shape of a rectangular parallelepiped, where one of the upper ends is folded diagonally, (a) forming a prismatic tubular structure (b) which It allows to fold completely (c) generating a series of six-sided pre-folds (d) and (e), as can be seen in Figure 4.

By extending the central body (2) by means of the folds an 8-sided structure is obtained that is inserted at the bottom of the initially developed structure coinciding with each side with the bottom side, then the flaps are glued with the central body and The octagonal box is formed, this can be seen in Figure 4, where the stages a, b, c, d, e for the formation of the central body (2) are shown.

The box can be easily transported, since the bottom can be folded over the center of the bottom (50) causing the entire structure to fold inwards, so it is not necessary to assemble the entire structure every time it is transported, since it would be enough to deploy the box again through the center of the bottom (50) when required, thus obtaining the complete box, in this way the box when storing and transporting occupies the smallest possible space.

The box of the present invention is a high performance packaging solution for the transport and storage of bulky material, such as granulated, powdered or loose products, the box is made of high performance corrugated cardboard and can be mounted manually It is also a cost-effective and ecological alternative to wooden or metal drawers. The lightweight but high performance material decreases the weight of the load, reducing costs.
