All said pieces are secured to the side of the box by means of end tabs (5), comprise a shared folding line (4-4') and are disposed in parallel. The end pieces (1) and the intermediate pieces (3) comprise pairs of grooves that determine lateral lugs (9-11) and central lugs (10-12) which, when the bottom is unfolded, connect together, the end lugs being disposed on the outer lower face of the bottom and the intermediate pieces connecting on the inner face of the bottom.

Description

SISTEMA DE CONFORMACIÓN DE UN FONDO ARMABLE PARA EMBALAJES  SYSTEM OF CONFORMATION OF A FUNDABLE ARMABLE FOR PACKAGING

PRISMÁTICOS DE BASE POLIGONAL  POLYGON BASED PRISMATS

DESCRIPCIÓN OBJETO DE LA INVENCIÓN DESCRIPTION OBJECT OF THE INVENTION

La presente invención se refiere a un sistema de conformación de un fondo armable para embalajes poligonales, siendo aplicable tanto a embalajes de contorno poligonal regular como a embalajes de contorno poligonal irregular, comprendiendo un número de piezas que se fijan sobre el exterior de las caras laterales del embalaje y cuyas piezas están dotadas de una línea de plegado intermedia para que desde una posición plegada el embalaje se despliegue el fondo y se obtenga el armado de la propia caja de forma totalmente automática. The present invention relates to a system for forming a reinforced bottom for polygonal packages, being applicable both to regular polygonal contour packaging and irregular polygonal contour packaging, comprising a number of pieces that are fixed on the outside of the side faces. of the packaging and whose parts are provided with an intermediate folding line so that from a folded position the packaging unfolds the bottom and the assembly of the box itself is obtained fully automatically.

ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION

Se conocen numerosos y variados tipos de fondos para embalajes prismáticos con bases poligonales de diferente número de lados que permiten el plegado del embalaje y por lo tanto el plegado del fondo, para que el embalaje pueda ser almacenado totalmente plegado ocupando un mínimo volumen y presentando un armado por despliegue del dispositivo totalmente automático debido a la configuración del propio fondo. En tal sentido pueden citarse los documentos ES 2268572 que se refiere a un contendor aplanable de cartón ondulado, que incluye un número de caras laterales de las que se derivan, en correspondencia con uno de sus bordes, aletas que permiten conformar un fondo para el contendor. Igualmente puede citarse el documento ES 2230182 en el que se describe igualmente un envase plegable de cartón ondulado, con un fondo determinado por piezas que se fijan, a través de aletas extremas a las caras laterales del propio envase. Estas piezas, dotadas de una línea de plegado transversal, presentan unas ranuras arqueadas que permiten el engarce de unas con otras en el plegado y en el desplegado, aunque en virtud de la trayectoria arqueada de las ranuras, las operaciones de plegado y desplegado presentan dificultades. Numerous and varied types of funds are known for prismatic packaging with polygonal bases of different number of sides that allow the folding of the packaging and therefore the folding of the bottom, so that the packaging can be stored fully folded occupying a minimum volume and presenting a armed by fully automatic device deployment due to the configuration of the fund itself. In this regard, documents ES 2268572 can be mentioned, which refers to a flattened corrugated cardboard container, which includes a number of lateral faces from which, in correspondence with one of its edges, fins that allow forming a bottom for the container are derived . Likewise, document ES 2230182 may be cited, which also describes a foldable corrugated cardboard container, with a bottom determined by fixing parts, through end fins to the side faces of the package itself. These pieces, equipped with a transverse folding line, have arcuate grooves that allow crimping with each other in folding and unfolding, although due to the arched path of the grooves, folding and unfolding operations present difficulties .

Además, en este documento tal y como está concebido, no es posible su aplicación a contenedores o envases en los que su base se corresponda con un polígono irregular. In addition, in this document as it is conceived, it is not possible to apply it to containers or containers in which its base corresponds to an irregular polygon.

Paralelamente, en el documento EP 1225130 hace referencia a un fondo armable para embalajes prismáticos de base poligonal con un número par de caras y mayor de seis, que si bien puede ser tanto regular como irregular asimétrico, su sistema de montaje hace que su fondo no sea todo lo resistente que sería deseable, característica fundamental para la mayoría de este tipo de envases. In parallel, in EP 1225130 it refers to an armored bottom for polygonal-based prismatic packages with an even number of faces and greater than six, which although it can be both regular and asymmetrical irregular, its mounting system makes its bottom not be as resistant as would be desirable, a fundamental characteristic for most of this type of packaging.

DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION

El sistema de conformación de un fondo armable para embalajes prismáticos de base poligonal que se preconiza presenta unas características de las que se derivan ventajas y nuevas prestaciones frente a los documentos citados en el apartado anterior y respecto a otros embalajes conocidos y existentes en el mercado. The conformation system of an armored fund for prismatic polygonal-based packaging that is recommended has characteristics that give rise to advantages and new benefits compared to the documents cited in the previous section and with respect to other packages known and existing in the market.

Más concretamente, el sistema de la invención se basa en que el mismo es aplicable tanto a embalajes de contorno poligonal regular como a embalajes de contorno poligonal irregular, siempre que en dicho contorno poligonal se defina un eje de anti-simetría, siendo aplicable a polígonos de cualquier número par de lados igual o mayor que ocho. More specifically, the system of the invention is based on the fact that it is applicable to both regular polygonal contour packaging and irregular polygonal contour packaging, provided that in said polygonal contour an anti-symmetry axis is defined, being applicable to polygons of any even number of sides equal to or greater than eight.

El fondo en cuestión se conforma a partir de cuatro piezas, dependiendo del número de caras que tenga el embalaje, de cuyas piezas dos de ellas, que corresponden a los extremos, son iguales entre sí, contando con dos piezas intermedias que dependiendo del número de lados una de ellas es susceptible de repetirse dos, tres o más veces, con ligeras variaciones para adaptarse al polígono concreto buscado. The bottom in question is formed from four pieces, depending on the number of faces that the packaging has, of which two pieces of them, which correspond to the ends, are equal to each other, with two intermediate pieces that depending on the number of sides one of them is likely to be repeated two, three or more times, with slight variations to adapt to the specific polygon sought.

En cualquier caso, todas estas piezas están afectadas de una línea de plegado intermedia y transversal, en donde las dos piezas extremas e iguales están afectadas de una pareja de ranuras una a cada lado de la línea transversal de plegado, mientras que una de las piezas intermedias, concretamente la que se repite en función del número de caras del polígono a obtener, presenta también una pareja de ranuras, una orejeta central y dos orejetas laterales, configuración básica que, como se acaba de decir se mantiene en el resto de piezas necesarias para formar la base poligonal de que se trate, mientras que la otra pieza central presenta una configuración alargada, con dos rebajes en correspondencia con los bordes de sus caras mayores, rematándose por sus extremos en sendas aletas de fijación a las caras laterales de la caja. A partir de esta estructuración, para un embalaje de contorno octogonal participaran dos piezas extremas y dos piezas intermedias, siendo preciso una pieza intermedia extra para cada dos caras extra que se pretendan obtener en el embalaje. In any case, all these pieces are affected by an intermediate and transverse folding line, where the two extreme and equal pieces are affected by a pair of grooves one on each side of the transverse folding line, while one of the intermediate pieces, specifically the one that is repeated based on the number of faces of the polygon to be obtained, also has a pair of grooves, a central lug and two lugs lateral, basic configuration that, as just said, is maintained in the rest of the pieces necessary to form the polygonal base in question, while the other central part has an elongated configuration, with two recesses corresponding to the edges of its larger faces, finishing off at their ends in two fixing fins to the side faces of the box. From this structuring, for an octagonal contour packaging two extreme pieces and two intermediate pieces will participate, being necessary an extra intermediate piece for every two extra faces that are intended to be obtained in the packaging.

Las aletas laterales a través de las cuales se fijan todas estas piezas que conforman el fondo a las caras laterales del embalaje están delimitadas por respectivas líneas de doblez para que dichas aletas se dispongan verticalmente y se fijen mediante adhesivo externa o internamente a las caras laterales del embalaje, de manera que dichas piezas que constituyen dicho fondo no se relacionan entre sí mediante ningún tipo de adhesivo, sino que su plegado y desplegado a través de la línea de doblez común y que se corresponde con un eje de simetría o anti-simetria del polígono a obtener, provoca el armado y desarmado automático del fondo. The lateral fins through which all these parts that make up the bottom are fixed to the lateral faces of the packaging are delimited by respective fold lines so that said fins are arranged vertically and fixed by external or internal adhesive to the lateral faces of the packaging, so that said pieces that constitute said bottom are not related to each other by any type of adhesive, but rather folded and unfolded through the common fold line and that corresponds to an axis of symmetry or anti-symmetry of the polygon to obtain, causes the arming and automatic disarming of the fund.

En caso de embalajes de contorno poligonal irregular, la línea de doblez que se define en las piezas no define dos mitades simétricas, como sucede en el caso de un fondo destinado a obtener un contorno poligonal regular, sino asimétricas, en donde una de ellas es de mayor amplitud y presenta una pareja de líneas de doblez para compensar los ángulos laterales y permitir que se mantenga la línea de doblez central de cada pieza. In the case of irregular polygonal contour packaging, the fold line defined in the pieces does not define two symmetric halves, as in the case of a fund intended to obtain a regular, but asymmetrical, polygonal contour, where one of them is of greater amplitude and presents a pair of fold lines to compensate the lateral angles and allow the central fold line of each piece to be maintained.

A partir de esta estructuración, las piezas se disponen paralelas y alineadas con la línea de doblez prevista y común para todas ellas, de manera que las parejas de ranuras que se definen en cada pieza hacen que las piezas en su desplegado encajen unas con otras por su extremidad opuesta en dichas parejas de ranuras centrales que se orientan hacia el interior, hasta alcanzar a la pieza intermedia que no dispone de ranuras a partir de la cual la orientación de dichas ranuras será inversa. DESCRIPCIÓN DE LOS DIBUJOS From this structuring, the pieces are arranged parallel and aligned with the planned and common fold line for all of them, so that the pairs of grooves that are defined in each piece make the pieces in their deployment fit with each other by their opposite extremity in said pairs of central grooves that are oriented inwards, until reaching the intermediate piece that does not have grooves from which the orientation of said grooves will be inverse.

Las figuras 8 y 9.- Muestran sendas vistas en perspectiva interior y exterior de un fondo de contorno irregular obtenido a partir de las piezas de la figura 7. Figure 7 shows a plan view of the four pieces that participate in the formation of an irregular bottom with eight sides. Figures 8 and 9.- They show paths in interior and exterior perspective of an irregular contour bottom obtained from the pieces of figure 7.

REALIZACIÓN PREFERENTE DE LA INVENCIÓN A la vista de las figuras reseñadas, y en concreto en las figuras 1 y 2, puede observarse la conformación de un fondo correspondiente a un embalaje de ocho caras, es decir fondo de contorno poligonal regular de ocho lados, participando en este caso cuatro piezas, las mostradas en la figura 5, dos piezas extremas (1) y dos piezas intermedias (2) y (3). PREFERRED EMBODIMENT OF THE INVENTION In view of the figures outlined, and in particular in Figures 1 and 2, the conformation of a bottom corresponding to an eight-sided packing can be observed, that is to say regular polygonal contour bottom of eight sides, in this case four pieces participating , those shown in Figure 5, two end pieces (1) and two intermediate pieces (2) and (3).

Todas estas piezas presentan una línea de plegado transversal e intermedia (4), así como sendas aletas extremas (5), a través de las cuales dichas piezas se fijan a la superficie externa de las caras laterales del embalaje por medio de las correspondientes líneas de doblez (6). All these pieces have a transverse and intermediate folding line (4), as well as two extreme fins (5), through which said pieces are fixed to the outer surface of the lateral sides of the packaging by means of the corresponding lines of fold (6).

Las piezas extremas (1) presentan una pareja de ranuras (7), en correspondencia con su borde interno mientras que la pieza intermedia (3) presenta también una pareja de ranuras (8), mientras que la pieza intermedia (2) carece de este tipo de ranuras. En cualquier caso, las piezas se fijan, como se decía a la superficie externa de las caras laterales del embalaje por medio de las aletas (5), para que en el armado se forme, tras las líneas de doblez intermedias (4), orejetas laterales (9) en las piezas extremas (1) y orejetas laterales (1 1) y central (12) en la pieza intermedia (3), todo ello de manera tal que en el armado la orejeta central (12) de la pieza intermedia (3) queda dispuesta por el interior del fondo, definido inicialmente a partir de la pieza intermedia (2), así como la orejeta central (10) de las piezas extremas, mientras que las orejetas laterales (9) de las piezas extremas (1) quedan por el exterior del fondo, al igual que las orejetas laterales (1 1) de la pieza intermedia (3), todo ello gracias al desplazamiento relativo entre piezas que se hace posible en base a las ranuras (7) y (8) que se definen entre las piezas. The end pieces (1) have a pair of grooves (7), in correspondence with their inner edge while the intermediate piece (3) also has a pair of grooves (8), while the intermediate piece (2) lacks this type of slots. In any case, the pieces are fixed, as it was said to the outer surface of the lateral faces of the packaging by means of the fins (5), so that in the assembly it is formed, after the intermediate fold lines (4), lugs lateral (9) in the end pieces (1) and lateral lugs (1 1) and central lugs (12) in the intermediate piece (3), all in such a way that in the assembly the central lug (12) of the intermediate piece (3) is arranged inside the bottom, initially defined from the intermediate piece (2), as well as the central lug (10) of the end pieces, while the side lugs (9) of the end pieces (1 ) are on the outside of the bottom, like the lateral lugs (1 1) of the intermediate piece (3), all thanks to the relative displacement between pieces that is made possible based on the grooves (7) and (8) that are defined between the pieces.

Esta constitución y características se repiten en todas las piezas que participan en la constitución del fondo del embalaje, ya sea de ocho lados como el de doce lados que se representa en las figuras 3 y 4, de dieciséis lados, como el mostrado en la figura 6, etc. En cualquier caso, y tratándose de fondos regulares, tal y como se ha comentado anteriormente, para un mayor número de lados será preciso la inclusión de una pieza intermedia (3) adicional, para cada dos lados extra que se pretendan obtener, que si bien presentará unas dimensiones acordes al polígono a obtener, mantiene como denominador común con la pieza intermedia anteriormente descrita la incorporación de una línea de plegado intermedia (4), un pareja de ranuras (8) paralelas en correspondencia con uno de sus lados mayores, y una pareja de aletas extremas (5) para su fijación a las caras externas del embalaje, piezas que se irán disponiendo paralelamente, y que en su plegado y desplegado se relacionan de igual manera a la descrita para la pieza intermedia (3) en lo que respecta a las orejetas central y laterales que se definen a partir de dicha ranuras (8). This constitution and characteristics are repeated in all the pieces that participate in the constitution of the bottom of the packaging, either of eight sides like the one of twelve sides that is represented in figures 3 and 4, of sixteen sides, like the one shown in the figure 6, etc. In any case, and in the case of regular funds, as mentioned above, for a greater number of sides it will be necessary to include an additional intermediate piece (3), for every two extra sides that are intended to be obtained, which although it will have dimensions according to the polygon to be obtained, it maintains as a common denominator with the intermediate piece described above the incorporation of an intermediate folding line (4), a pair of parallel grooves (8) in correspondence with one of its major sides, and a pair of extreme fins (5) for fixing to the external faces of the packaging, parts that will be arranged in parallel, and that in their folding and unfolding are related in the same way to that described for the intermediate piece ( 3) as regards the central and lateral lugs defined from said grooves (8).

En cuanto a los fondos de contorno irregular, como el mostrado en las figuras 7 a 9, en los mismos participa igualmente una pareja de piezas extremas (V) con su correspondiente línea de doblez (4'), aletas (5') y ranuras (7') que definen orejetas laterales (9'), así como dos piezas intermedias (2') y (3'), una de las cuales, concretamente la pieza (3') presenta unas ranuras (8') en uno de sus bordes laterales, que definen orejetas (11 '), si bien en este caso la línea de doblez (4') define para estas piezas dos mitades asimétricas, siendo las orejetas de estas piezas también asimétricas, pero con un funcionamiento y armado idéntico al de los casos anteriormente descritos, con la particularidad de que las piezas intermedias (3') y (2') presentan una pareja de líneas de doblez (13) oblicuas que permiten compensar los ángulos laterales mediante el pliegue de las aletas correspondiente y que corresponderán a las caras que tenga mayor ángulo para que se mantenga la línea de doblez central (4') de cada sector establecido a uno y otro lado del plano de doblez del conjunto del fondo, siendo esta estructuración solamente aplicable a polígonos irregulares pero que presenten un eje de antisimetría. As for the irregular contour bottoms, such as the one shown in figures 7 to 9, a pair of end pieces (V) with their corresponding fold line (4 '), fins (5') and grooves also participate. (7 ') defining lateral lugs (9'), as well as two intermediate pieces (2 ') and (3'), one of which, specifically the piece (3 ') has grooves (8') in one of its lateral edges, which define lugs (11 '), although in this case the fold line (4') defines for these pieces two asymmetric halves, the lugs of these pieces being also asymmetrical, but with identical operation and assembly to of the cases described above, with the particularity that the intermediate pieces (3 ') and (2') have a pair of oblique fold lines (13) that allow compensating the lateral angles by folding the corresponding fins and that will correspond to the faces that have a greater angle so that the double line is maintained ez central (4 ') of each sector established on either side of the plane of fold of the fund as a whole, this structuring being only applicable to irregular polygons but presenting an axis of antisymmetry.
