La presente invención se refiere a un recipiente plegable, que es del tipo de los que se constituyen con una gran capacidad y en el que la configuración general del mismo es prismática de contorno octogonal, y en donde la superficie lateral formando todas las caras estará constituida a partir del desarrollo de una lámina de cartón The present invention relates to a collapsible container, which is of the type that is constituted with a large capacity and in which the general configuration thereof is octagonal contour prismatic, and where the lateral surface forming all faces will be constituted from the development of a cardboard sheet

o material similar, mientras que el fondo está constituido por dos piezas que se interacoplan entre sí. or similar material, while the bottom consists of two pieces that interconnect with each other.

El objeto de la invención es conseguir un recipiente del tipo referido con anterioridad, en el que la construcción y armado del mismo, y por supuesto su plegado/desplegado, se realice con sencillez y facilidad. The object of the invention is to achieve a container of the type referred to above, in which the construction and assembly thereof, and of course its folding / unfolding, is carried out simply and easily.

BACKGROUND OF THE INVENTION

En la Patente Europea con número de publicación 2281052 se describe un recipiente de contorno octogonal, en el que la superficie lateral está formada por una lámina y el fondo por dos láminas, convenientemente plegables para formar el cuerpo, con posibilidad de plegarse y desplegarse, es decir ocupar una posición plana en la situación de plegado y una posición tubular de contorno octogonal en la posición desplegada o de uso. In the European Patent with publication number 2281052 an octagonal contour container is described, in which the lateral surface is formed by a sheet and the bottom by two sheets, conveniently foldable to form the body, with the possibility of folding and unfolding, is say occupy a flat position in the folding situation and a tubular position of octagonal contour in the deployed or use position.

En este recipiente las dos piezas que constituyen el fondo son de un desarrollo plano complejo, es decir que está formada por varias partes o sectores que en primer lugar dificulta el montaje de lo que es el fondo del contenedor, y en segundo lugar dificulta y ofrece problemas a la hora de llevar a cabo el plegado y desplegado del propio contenedor o recipiente. In this container the two pieces that constitute the bottom are of a complex flat development, that is to say that it is formed by several parts or sectors that in the first place makes difficult the assembly of what is the bottom of the container, and in the second place it makes difficult and offers problems when carrying out the folding and unfolding of the container itself.

DESCRIPTION OF THE INVENTION

El recipiente plegable que se preconiza, basado precisamente en el concepto descrito y ya expuesto como antecedente en esa Patente Europea citada en el apartado anterior, presenta unas particularidades en lo que respecta a las dos piezas que constituyen el fondo, que derivan en una simplificación estructural de dicho fondo y en una simplificación y facilidad a la hora de llevar a cabo el plegado para obtener el recipiente plano en posición de reposo o no utilizable y en el desplegado para conseguir la posición de trabajo o de uso, es decir de la conformación tubular de contorno octogonal. The foldable container that is recommended, based precisely on the concept described and already set forth as a precedent in that European Patent cited in the previous section, presents some peculiarities with regard to the two pieces that constitute the bottom, which result in a structural simplification of said bottom and in a simplification and ease at the time of carrying out the folding to obtain the flat container in rest or unusable position and in the unfolding to achieve the working or use position, that is to say of the tubular conformation octagonal contour.

Mas concretamente, el recipiente de la invención se constituye, como ya se ha dicho y como es convencional, mediante tres piezas, una correspondiente a una pieza rectangular con una pluralidad de líneas transversales de doblez para que en el armado forme un cuerpo tubular prismático de contorno octogonal, delimitándose entre las líneas de doblez las correspondientes paredes laterales del recipiente, cerrándose sobre si misma mediante una solapa prevista en uno de los bordes extremos de la pieza rectangular que constituye el cuerpo tubular del recipiente. More specifically, the container of the invention is constituted, as already said and as is conventional, by means of three pieces, one corresponding to a rectangular piece with a plurality of transverse bending lines so that in the assembly it forms a prismatic tubular body of Octagonal contour, delimiting the corresponding side walls of the container between the fold lines, closing on itself by means of a flap provided on one of the end edges of the rectangular piece that constitutes the tubular body of the container.

Por su parte, las dos piezas que participan en la constitución del fondo, son iguales entre si y cada una de ellas está formada por dos mitades delimitadas por una línea de doblez intermedia, de manera que cada pieza presenta en correspondencia con los extremos de la línea de doblez, una escotadura angular que establece el medio de vinculación con la otra pieza del fondo, es decir que se interrelacionan entre si a través de esas escotaduras enfrentadas, de manera tal que las porciones o sectores de cada mitad de las respectivas piezas de fondo y que se establecen entre el fondo de la escotadura y la parte abierta de la misma, se solapan entre si en el engarce entre ambas piezas, estableciendo un medio de vinculación sencillo. On the other hand, the two pieces that participate in the constitution of the fund, are equal to each other and each one of them is formed by two halves delimited by an intermediate fold line, so that each piece presents in correspondence with the ends of the fold line, an angular recess that establishes the means of linking with the other piece of the bottom, that is to say that they interrelate with each other through these facing recesses, so that the portions or sectors of each half of the respective pieces of bottom and that are established between the bottom of the recess and the open part of it, overlap each other in the crimp between both pieces, establishing a simple means of linking.

Por otro lado, cada pieza constituye un semi-octógono en lo que respecta al desarrollo de la misma, y en cuyo semi-octógono lógicamente se determinan cuatro lados contiguos, dos a cada lado del otro extremo de la línea de plegado intermedia de cada pieza, de manera tal que en correspondencia con cada lado se deriva una solapa, resultando dos solapas intermedias que son de mayor altura que las dos solapas extremas, y éstas dotadas de una línea de doblez doble, que en el montaje quedan adosadas a sendos lados, en correspondencia con la cara interna, de las paredes laterales del cuerpo tubular octogonal, mientras que las otras dos solapas, es decir las de mayor altura, se relacionan entre si a través del encolado que se realiza mediante una aleta derivada de una de ellas que se adosa y se fija por encolado sobre la cara interna de la otra solapa, formándose así un fondo formado por las dos mitades en que las solapas quedan adheridas por encolado o por cualquier otro sistema apropiado, a las respectivas caras o paredes del cuerpo tubular octogonal. On the other hand, each piece constitutes a semi-octagon in regard to its development, and in which semi-octagon logically determines four contiguous sides, two on each side of the other end of the intermediate folding line of each piece , so that in correspondence with each side a flap is derived, resulting in two intermediate flaps that are of greater height than the two extreme flaps, and these equipped with a double fold line, which in the assembly are attached to each side, in correspondence with the internal face, of the lateral walls of the octagonal tubular body, while the other two flaps, that is to say those of greater height, are related to each other through the gluing that is carried out by means of a fin derived from one of them that it is attached and fixed by gluing on the inner face of the other flap, thus forming a bottom formed by the two halves in which the flaps are adhered by gluing or by any other appropriate system attached to the respective faces or walls of the octagonal tubular body.

De esta forma, desde la posición, por ejemplo, desplegada y constituyendo el recipiente prismático de contorno octogonal, para efectuar el plegado se efectúa la doblez a través de dos aristas opuestas del cuerpo tubular octogonal, a la vez que a través de las dos líneas de doblez intermedias correspondientes a las dos piezas del fondo, se pliegan asimismo esas piezas del fondo, llevándose consigo un plegado total tanto de la superficie lateral como del fondo del recipiente que constituyen las piezas comentadas. In this way, from the position, for example, deployed and constituting the octagonal contour prismatic container, the folding is carried out by means of two opposite edges of the octagonal tubular body, at the same time as through the two lines of intermediate bending corresponding to the two pieces of the bottom, those pieces of the bottom are also folded, taking with it a total folding of both the lateral surface and the bottom of the container that constitute the commented pieces.

PREFERRED EMBODIMENT OF THE INVENTION

Como se puede ver en las figuras referidas, el recipiente de la invención se obtiene mediante tres piezas, una que corresponde al desarrollo de la lámina rectangular (1) representada en la figura 1, y otras dos iguales, mostrándose una de ellas en la figura 2, correspondiendo igualmente al desarrollo de una lámina (2) para cada una de estas piezas que han de formar el fondo. As can be seen in the aforementioned figures, the container of the invention is obtained by means of three pieces, one corresponding to the development of the rectangular sheet (1) represented in figure 1, and two others the same, showing one of them in the figure 2, also corresponding to the development of a sheet (2) for each of these pieces that have to form the bottom.

Pues bien, la pieza laminar, que será preferentemente de cartón u otro material similar, que ha de constituir la superficie lateral del recipiente, presenta líneas de doblez transversales y equidistantes (3) que delimitan sectores rectangulares (4) que han de formar las paredes laterales del cuerpo lateral correspondiente al recipiente, que en este caso es de contorno octogonal, por lo que dicho cuerpo lateral será prismático de contorno octogonal, presentando una solapa (5) en correspondencia con uno de los bordes laterales para mediante encolado sobre la pared lateral opuesta, configurar el contorno octogonal del cuerpo prismático tubular en el cierre sobre si mismo de esa lámina (1). Well, the laminar piece, which will preferably be made of cardboard or other similar material, which should constitute the lateral surface of the container, has transverse and equidistant bending lines (3) that delimit rectangular sectors (4) that must form the walls lateral of the lateral body corresponding to the container, which in this case is of octagonal contour, whereby said lateral body will be prismatic of octagonal contour, presenting a flap (5) in correspondence with one of the lateral edges for gluing on the side wall opposite, configure the octagonal contour of the tubular prismatic body in the closure on itself of that sheet (1).

Por su parte, cada una de las piezas (2) que han de constituir el fondo, está formada por una lámina que a partir de una imaginaria línea (6) señalada en trazo de puntos en la figura 2, se deriva en cada pieza un contorno semi-octogonal de cuyos lados (7) se derivan otras tantas solapas, dos de ellas intermedias (8) y dos extremas (9), siendo las solapas (8) de mayor altura que las solapas (9), ya que tales solapas (8, 9) están previstas para acodarse perpendicularmente a las dos mitades (10) de ese contorno semi-octogonal de la pieza (2). On the other hand, each of the pieces (2) that are to constitute the bottom, is formed by a sheet that, from an imaginary line (6) indicated in dotted lines in figure 2, derives in each piece a semi-octagonal contour of whose sides (7) derive as many flaps, two of them intermediate (8) and two extremes (9), the flaps (8) being higher than the flaps (9), since such flaps (8, 9) are provided to be perpendicular to the two halves (10) of that semi-octagonal contour of the piece (2).

Dicha pieza (2) presenta una línea intermedia de doblez (11) que por uno de sus extremos finaliza en la imaginaria línea (6), de manera que a partir de esta línea (6), al otro lado de las mitades (10) se establecen extensiones (12), delimitadas por una escotadura (13) cuya función se expondrá con posterioridad. Said piece (2) has an intermediate fold line (11) that ends at the imaginary line (6) at one end, so that from this line (6), on the other side of the halves (10) extensions (12) are established, delimited by a recess (13) whose function will be explained later.

En la constitución del fondo mediante las dos piezas (2) se lleva a cabo la interrelación de éstas a través de las escotaduras (13) de las mismas, engarzando entre si para que las extensiones (12) queden superpuestas alternadamente, mientras que las solapas (8, 9) se acodan ortogonalmente como anteriormente se ha dicho, para que las solapas (8) queden fijadas entre si mediante una aleta (14) derivada de una de ellas que se fija por encolado a la otra solapa (8), mientras que las solapas (9) quedan fijadas, también por encolado y al igual que las solapas (8) a la superficie correspondiente a la cara interna de las paredes (4) del cuerpo tubular octogonal que se obtiene a partir de la lámina (1). In the constitution of the bottom by means of the two pieces (2) the interrelation of these is carried out through the recesses (13) of the same, crimping together so that the extensions (12) are superimposed alternately, while the flaps (8, 9) they are orthogonally layered as previously mentioned, so that the flaps (8) are fixed together by a fin (14) derived from one of them that is fixed by gluing to the other flap (8), while that the flaps (9) are fixed, also by gluing and like the flaps (8) to the surface corresponding to the inner face of the walls (4) of the octagonal tubular body that is obtained from the sheet (1) .

Las solapas (9) presentan líneas de doblez dobles, como ya se ha dicho, para facilitar el plegado y desplegado. The flaps (9) have double fold lines, as already mentioned, to facilitate folding and unfolding.

De acuerdo con estas características, y una vez montadas las dos piezas (2) constituyendo el fondo, engarzadas entre si de la manera descrita, y fijado a la cara interna de las paredes laterales del cuerpo tubular del recipiente, el plegado y desplegado se realiza de la forma siguiente: According to these characteristics, and once assembled the two pieces (2) constituting the bottom, crimped together in the manner described, and fixed to the inner face of the side walls of the tubular body of the container, folding and unfolding is carried out as follows:

Tal y como se representa en la figura 4 y a partir de la configuración de la figura 5, se lleva a cabo el plegado del cuerpo tubular octogonal a través de dos aristas opuestas, de manera tal que en ese plegado se produce automáticamente el plegado de las dos piezas (2) a través de la línea de doblez intermedia (11) de cada una de éstas, obteniéndose así un cuerpo totalmente plegado y que corresponde al contenedor con su fondo, mientras que el desplegado para formar otra vez de nuevo el recipiente se efectúa por desplegado del cuerpo tubular, que automáticamente lleva consigo el desplegado de las mitades (10) correspondientes a las dos piezas (2) del fondo. As shown in Figure 4 and from the configuration of Figure 5, the folding of the octagonal tubular body is carried out through two opposite edges, such that in that folding the folding of the parts is automatically produced. two pieces (2) through the intermediate fold line (11) of each of these, thus obtaining a fully folded body and corresponding to the container with its bottom, while the deployed to reshape the container again carried out by unfolding the tubular body, which automatically carries with it the deployment of the halves (10) corresponding to the two pieces (2) of the bottom.
