DESCRIPTION

Cardboard container.

OBJECT OF THE INVENTION 5

The present invention, as expressed in the statement of this specification, refers to a cardboard package that integrates a bottom and four side walls parallel two to two, in combination with corner portions joining pairs of adjacent side walls . 10

The mouth of the container is closed by two first opposing flaps that start from upper edges of two parallel side walls and two second opposing flaps that start from upper edges of the other two parallel side walls, where the four side walls include bottom edges. 15 corresponding to the bottom of the container.

Starting from this premise, the objective of the invention is to achieve a solid and stiffening solid by means of the two pairs of opposing flaps that close the mouth of the container of the invention. twenty

TECHNICAL PROBLEM TO BE RESOLVED AND BACKGROUND OF THE INVENTION

At present, a multitude of cardboard packages are known, among which the German patent with publication No. DE 197011210 and the German utility model with publication No. DE 29724272 U, comprising four side walls joined together by pairs of corner portions, the packages also including first flaps to form the bottoms and second flaps to close the mouths of the packages, so that some and other flaps tear from upper and lower edges of said side walls. 30

All the flaps have smaller opposing edges, parts of which are adapted to the corner areas of the bottom and mouth.

The German invention patent with publication number DE 9116739 refers to a cardboard package that also includes side walls in combination with corner portions that join pairs of adjacent side walls, where the bottoms are formed by pairs of flaps that start of the lower edges of the side walls, while the mouth of the container is closed by other pairs of flaps that start from the upper edges of said side walls. 40

In an embodiment of said German patent (Figures 17 to 19) it is noted that two opposing flaps of the bottom and mouth of the container have a rectangular shape, while the other two opposing flaps of that bottom and mouth have rectangular major parts and parts minor trapezoids, whose minor bases start from two of the opposite side walls of the container, the inclined sides of those minor parts of the opposing flaps corresponding to the corner portions joining pairs of adjacent side walls.

It is also known the utility model with publication number in Spain ES 1065219 that 50 refers to a cardboard box of similar characteristics to the package described in German patent DE 9116739 cited above, where two pairs of opposing flaps are arranged in correspondence with the mouth of the box to close it.

All these packages generally have problems of rigidity to a greater or lesser degree, once these packages are assembled,

DESCRIPTION OF THE INVENTION 5

In order to achieve the objectives and avoid the drawbacks mentioned in the previous sections, the invention proposes a cardboard package comprising a bottom, two first side walls parallel to each other and two second side walls parallel to each other, in combination with portions cornering joining pairs of adjacent side walls 10; the mouth of the container being closed by means of two first opposing flaps and by means of two second opposing flaps that start all of them from upper edges of the four lateral walls, said upper edges corresponding with fold lines.

 fifteen

The four opposing flaps include larger edges that are parallel to the upper edges of the side walls from which the side walls start by bending lines.

The first and second opposing flaps have pairs of opposite asymmetric edges 20, one of which has a larger initial section in accordance with the respective corner portion, a straight intermediate section perpendicular to the major edge of the opposing flaps, and an extreme section formed by a angular cutout of rounded vertex; where the largest initial section is the same width as the corner portions.

 25

The other even asymmetric edge of the opposing flaps has a smaller initial section in accordance with the respective corner portion, an intermediate section formed by a trapezoidal cut and a straight end section that is perpendicular to the major edge of the opposing flaps; where the initial minor section has a length less than the width of the corner portions. 30

The major and minor initial sections of the first opposing flaps butt against the inner faces of the corner portions; while the straight intermediate sections thus the straight end sections of those first opposing flaps butt against the inner faces of the second side walls of the container. 35

The second opposing flaps are attached against the first opposing flaps; where the major initial sections of the second opposing flaps correspond to the minor initial sections of the first opposing flaps; and where the minor initial sections of the second opposing flaps correspond to the initial major sections 40 of the first opposing flaps.

To assemble the container, the conformation of the four side walls is first assembled generating a tubular configuration and then the bottom and the closure of the mouth of the container are formed by folding 90º of the first opposing flaps 45 until they fit inside from the container and then proceed to fold the second opposing flaps by also folding them 90 ° by attaching against the first opposing flaps.

In order to facilitate a better understanding of this descriptive report and forming an integral part thereof, a series of figures are attached in which the object of the invention has been shown as an illustrative and non-limiting nature.

DESCRIPTION OF AN EXAMPLE OF EMBODIMENT OF THE INVENTION

Considering the numbering adopted in the figures, the cardboard package comprises a bottom, two first side walls (1) parallel to each other and two second side walls (2) parallel to each other, in combination with corner portions (3) joining pairs of adjacent side walls (1), (2).

The mouth of the container is closed by two first opposing flaps (4) and 15 by two second opposing flaps (5).

The four opposing flaps (4), (5) start from upper edges of the four side walls (1), (2), including the four side walls (1), (2) corresponding bottom edges with the bottom of the container . The four opposing flaps (4), (5) 20 include larger edges (6) that are parallel to the upper edges of the side walls (1), (2) from which the side walls (1), (2) start. by means of fold lines (7).

The first and second opposing flaps (4) and (5) have pairs of asymmetric edges 25 facing each other, one of which has a larger initial section (8) according to the respective corner portion (3), a straight intermediate section (9) perpendicular to the major edge (6) of the opposing flaps, and an end section (10) formed by an angular cut of rounded vertex.

 30

The other even asymmetric edge of the flaps (4), (5) has a smaller initial section (8 ') also in accordance with the respective corner portion (3), an intermediate section (9') formed by a trapezoidal cut and a section straight end (10 ') that is perpendicular to the major edge (6) of the opposing flaps (4), (5).

 35

With this arrangement described, to assemble the container, the conformation of the four side walls (1), (2) is first assembled generating a tubular configuration, and then the bottom and the closure of the mouth of the container is formed.

To do this, first of all, the first opposing flaps 40 (4) are folded inside the package by folding them 90 °. In this operation, the initial sections (8), (8 ’) stop against the inner faces of the corner portions (3); while the straight intermediate sections (9) and the straight end sections (10) butt against the inner faces of the second side walls (1).

 Four. Five

Secondly, the second opposing flaps (5) are folded into the interior of the package until they stop against the first opposing flaps (4) previously shot down.

As shown in Figure 1, the package of the invention is obtained from a sheet 50 of cardboard, where the conformation of the adjacent asymmetric edges that are complementary is highlighted, so that two adjacent asymmetric edges are separated by a common die cutting (11).

On the other hand, it should be noted that in two diagonally opposite corners of the mouth of the container, the major initial sections (8) of the asymmetric edges of the first opposing flaps (4) cover the entire width of the corner portions (3), while that in the other two diagonally opposite corners of the mouth of the container, the initial sections 5 smaller (8 ') of the first opposing flaps (4) have a length less than the width of the respective corner portions (3).

The side walls (1), (2) are joined to the corner portions (3) by other bending lines (12). 10
