Caja-estuche de cartónCardboard box-case

SECTOR DE LA TÉCNICASECTOR OF THE TECHNIQUE

La presente invención se refiere a una caja-estuche de cartón, que partiendo de un cuerpo monopieza, a partir de una lámina de cartón esencialmente rectangular, presenta una serie de líneas de plegado para permitir la conformación de una caja-estuche, de embocadura parcial o totalmente cerrada, sin necesidad de elementos de fijación o encolado como ocurre tradicionalmente.The present invention relates to a cardboard box-case, which, starting from a single-piece body, from an essentially rectangular cardboard sheet, presents a series of folding lines to allow the conformation of a box-case, of partial opening or fully closed, without the need for fixing or gluing elements as traditionally occurs.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Si bien son conocidos innumerables tipos de caja-estuches de cartón, la mayoría de éstas suelen ser de paredes simples, por lo que no son adecuadas para contener elementos de determinados pesos.Although innumerable types of cardboard box-cases are known, most of these are usually simple walls, so they are not suitable for containing elements of certain weights.

En cualquier caso, el solicitante desconoce la existencia de caja-estuches con una estructura suficientemente versátil que, en función de las dimensiones de su fondo, y sin variar el resto de la estructura de la caja-estuche, puedan obtenerse caja-estuches de tipo bandeja, de embocadura parcialmente estrangulada, caja-estuches con cierre completo de su embocadura y caja-estuches de alta resistencia en virtud de sus paredes múltiples.In any case, the applicant is unaware of the existence of box-cases with a sufficiently versatile structure that, depending on the dimensions of its bottom, and without changing the rest of the structure of the box-case, box-cases of type can be obtained tray, partially strangled mouth, case-boxes with full closure of its mouth and high-strength case-boxes by virtue of its multiple walls.

EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION

La caja-estuche de cartón que se preconiza viene a llenar el vacío técnico anteriormente expuesto.The cardboard box-box that is recommended comes to fill the technical void described above.

Para ello, la caja-estuche de la invención se constituye a partir de un cuerpo monopieza, materializado en una lámina rectangular de cartón que presenta seis líneas de doblez transversales, las dos centrales que constituirán el fondo en el montaje de la caja-estuche, de manera que el resto de líneas de plegado transversales determinarán tres sectores rectangulares a cada extremo del fondo, determinantes de las paredes extremas o anterior y posterior de la caja-estuche, así como las dos últimas, una doble pared que determina la semi-tapa de cierre parcial o total para la caja-estuche.For this, the case-box of the invention is constituted from a single-piece body, embodied in a rectangular cardboard sheet that has six transverse fold lines, the two centrals that will constitute the bottom in the assembly of the case-box, so that the rest of the cross fold lines will determine three sectors rectangular at each end of the bottom, determining the extreme or anterior and posterior walls of the case-box, as well as the last two, a double wall that determines the partial or total closing half-cover for the case-case.

Por otro lado, se ha previsto que los laterales del sector central o fondo se prolonguen en sendos sectores rectangulares que forman los testeros, a partir de los cuales y tras la oportuna línea de doblez, se prolongan lateralmente, tras las correspondientes líneas de doblez, en dos alas prolongación a su vez de los dos primeros sectores rectangulares que emergen de los extremos del fondo, estando provisto el primer ala con dos líneas de doblez diagonales que emergen del vértice inferior interno de dicho ala, y la segunda con una línea de doblez diagonal que emerge igualmente del vértice inferior interno de dicho ala, de manera que de fábrica el cuerpo laminar se suministra con las alas y sectores que emergen a cada lado de los cinco sectores centrales plegados sobre éstos, adoptando una disposición laminar, en la que el sector triangular y extremo de las alas extremas determinado por la citada línea de plegado diagonal queda fijado por encolado al sector que determina la pared externa de la sobretapa, de modo que en virtud de dichas líneas de plegado diagonales, al plegar hacia el interior los sectores determinantes de la cara externa de la sobretapa se provoca el despliegue automático de los testeros y de las alas que se establecen entre éstos y dicha sobretapa, de manera que los sectores extremos determinantes de la pared interna de la sobretapa se pliegan internamente sobre el sector del que emergen, contando con aletas que encajan en respectivas orificios establecidos en correspondencia con la línea de plegado de dichos sectores con respecto a las caras anterior y posterior de la caja-estuche, formando una doble pared, perfectamente estabilizada.On the other hand, it has been foreseen that the laterals of the central or bottom sector are prolonged in two rectangular sectors that form the front, from which and after the appropriate fold line, they extend laterally, after the corresponding fold lines, in two wings, in turn, prolonging the first two rectangular sectors that emerge from the ends of the bottom, the first wing being provided with two diagonal fold lines emerging from the lower inner vertex of said wing, and the second with a fold line diagonal that also emerges from the lower internal vertex of said wing, so that by default the laminar body is supplied with the wings and sectors that emerge on each side of the five central sectors folded over them, adopting a laminar arrangement, in which the triangular sector and end of the extreme wings determined by the said diagonal folding line is fixed by gluing to the sector that determines the pa external network of the overcap, so that by virtue of said diagonal folding lines, folding inwardly the determining sectors of the outer face of the overcap causes the automatic deployment of the pockets and the wings that are established between them and said overcap, so that the determining end sectors of the inner wall of the overcap are folded internally over the sector from which they emerge, counting on fins that fit into respective holes established in correspondence with the folding line of said sectors with respect to the front and back sides of the case-box, forming a double wall, perfectly stabilized.

De esta forma se obtiene en primera instancia una especie de bandeja, abierta superiormente, cuyos extremos, determinantes de las semi-tapas, son susceptibles de plegarse hacia el interior de la caja-estuche plegado que se consigue en virtud de las dobles líneas de plegado diagonales que se establecen en las alas que emergen de los testeros, obteniéndose así una caja-estuche cuya embocadura queda cerrada total o parcialmente por las semi-tapas citadas.In this way, a sort of tray is obtained in the first instance, open at the top, whose ends, determining the semi-covers, are capable of folding into the folded case-box that is achieved by virtue of the double folding lines. diagonals that are established in the wings that emerge from the heads, thus obtaining a case-box whose mouthpiece is closed totally or partially by the mentioned half-covers.

En tal sentido, la longitud del fondo de la caja-estuche, y consecuentemente de los testeros, determinará si las semi-tapas en el proceso de plegado hacia el interior de la cajaestuche determinarán unas semi tapas que cierran parcialmente la embocadura de la misma, o bien coinciden en el punto medio superior correspondiente a la zona intermedia de la caja-estuche, cerrando totalmente su embocadura, o incluso, reduciendo la longitud de dicho fondo y testeros puede conseguirse que una sobretapa se monte solapadamente sobre la otra, de modo que se obtenga así una caja-estuche sumamente resistente, con zonas en las que el grosor de pared es cuádruple.In this sense, the length of the bottom of the box-case, and consequently of the heads, will determine if the half-covers in the process of folding into the interior of the box case will determine some semi-covers that partially close the mouth of it, or coincide in the upper midpoint corresponding to the intermediate area of the box-case, completely closing its mouth, or even reducing the length of said bottom and pockets can get that an overcap is mounted overlappingly over the other, so that an extremely resistant case-box is obtained, with areas where the wall thickness is quadruple.

Sobre el fondo de la caja-estuche, o incluso afectando al fondo y testeros, podrá disponerse opcionalmente una lámina de cartón de refuerzo que mejore la resistencia de la caja-estuche cuando se requieran de unas prestaciones adicionales.On the bottom of the case-box, or even affecting the bottom and pockets, a reinforcing cardboard sheet that improves the strength of the case-box may optionally be provided when additional benefits are required.

Solo resta señalar por último que, las semi-tapas serán susceptibles de presentar parejas de orificios pasantes para respectivos cordones o cuerdas que determinen asas de agarre manual de los extremos de la caja-estuche.It only remains to point out that, the semi-covers will be capable of presenting pairs of through holes for respective cords or ropes that determine manual grip handles of the ends of the case-case.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION

A la vista de las figuras reseñadas, puede observarse como la caja-estuche-estuche de la invención presenta tres variantes de realización, en las que lo único que varía es la relación de dimensiones de la longitud del fondo de la caja-estuche con la altura de la misma, lo que determinará, como se puede ver en las figuras 4, 5 y 6, el que la caja-estuche en disposición de cierre sus semi-tapas cierren por completo la embocadura de la cajaestuche (figura 5), cierren parcialmente dicha embocadura (figura 6) o se superpongan (figura 4), reforzando así el conjunto de la caja-estuche.In view of the figures outlined, it can be seen how the case-case-case of the invention presents three variants of embodiment, in which the only thing that varies is the ratio of dimensions of the length of the bottom of the case-case with the height of the same, which will determine, as can be seen in figures 4, 5 and 6, that the case-case in closing arrangement its semi-covers completely close the mouth of the case (figure 5), close partially said mouthpiece (figure 6) or overlap (figure 4), thus reinforcing the case-case assembly.

Pues bien, en cualquiera de los casos la caja-estuche-estuche está constituida a partir de una lámina rectangular de cartón con seis líneas de doblez transversales, determinantes del fondo (1), paredes anterior y posterior (2), así como dos sectores contiguos (3-4) determinantes de respectivas semi-tapas de doble pared, para lo cual el sector extremo (4) se remata en sendas pestañas (10) encajables en ranuras (11) establecidas en la línea de plegado inferior del sector (3).Well, in any of the cases the case-case-case is constituted from a rectangular cardboard sheet with six transverse fold lines, bottom determinants (1), front and rear walls (2), as well as two sectors contiguous (3-4) determinants of respective double-walled semi-covers, for which the end sector (4) is finished off in tabs (10) fitted in grooves (11) established in the lower folding line of the sector (3) ).

Los laterales del fondo (1) se prolongan en sendos sectores rectangulares determinantes de los testeros (5) de manera que lateralmente a éstos y como prolongación de los sectores de las paredes posterior y anterior (2) y de los sectores (3) se establecen dos alas (6 y 7), estando provisto el primer ala (6) de dos líneas de doblez diagonales (8) que emergen del vértice inferior interno de dicho ala, y el segundo ala (7) con una línea de doblez diagonal (9) que emerge igualmente del vértice inferior interno de dicho ala.The sides of the bottom (1) extend into two rectangular sectors that determine the front (5) so that laterally to these and as an extension of the sectors of the back and front walls (2) and the sectors (3) are established two wings (6 and 7), the first wing (6) being provided with two diagonal bending lines (8) emerging from the lower inner vertex of said wing, and the second wing (7) with a diagonal bending line (9) which it also emerges from the lower internal vertex of said wing.

A partir de esta estructuración, y como se muestra en la figura 2, la caja-estuche se suministra de fábrica en una configuración aplanada de mínima ocupación, en la que las alas (6-7) y testeros (5) quedan plegadas sobre el interior de la caja-estuche y fijadas por encolado u otro medio a través de los sectores triangulares y extremos de las alas (7).From this structure, and as shown in Figure 2, the case-box is supplied at the factory in a flattened configuration of minimum occupancy, in which the wings (6-7) and heads (5) are folded over the inside the case-box and fixed by gluing or other means through the triangular sectors and ends of the wings (7).

De esta manera, el usuario de la caja-estuche no precisa de ningún tipo de herramienta o adhesivo a la hora de armar y cerrar la caja-estuche, de modo que, al plegar hacia el interior los sectores determinantes de la cara externa de la sobretapa (3) se provoca el despliegue automático de los testeros y de las alas que se establecen entre éstos y dicha sobretapa, de modo que los sectores extremos (4) determinantes de la pared interna de la sobretapa se pliegan internamente sobre el sector del que emergen, acoplándose sobre las ranuras (11) a través de sus pestañas (10) quedando la caja-estuche armada y abierta, lista para ser llenada y posteriormente cerrada.In this way, the user of the case-box does not require any type of tool or adhesive when assembling and closing the case-box, so that, when folding inwards the determining sectors of the external face of the overcap (3) the automatic deployment of the heads and of the wings that are established between them and said overcap is caused, so that the determining end sectors (4) of the inner wall of the overcap are folded internally over the sector of which they emerge, engaging on the grooves (11) through their tabs (10) leaving the box-case armed and open, ready to be filled and subsequently closed.

Para llevar a cabo el cierre, basta con abatir las sobretapas hacia el interior, maniobra que se ve sensiblemente facilitada en virtud de las dos líneas diagonales (8) de las alas (6).To carry out the closure, it is enough to fold the overcaps inwards, a maneuver that is significantly facilitated by virtue of the two diagonal lines (8) of the wings (6).

Sobre el fondo de la caja-estuche, o incluso afectando al fondo y testeros, podrá disponerse opcionalmente una lámina de cartón (14) de refuerzo que mejore la resistencia de la caja-estuche cuando se requieran de unas prestaciones adicionales.On the bottom of the case-box, or even affecting the bottom and pockets, a reinforcing cardboard sheet (14) may be optionally provided that improves the strength of the case-box when additional benefits are required.

Tal y como se ha dicho con anterioridad, las semi-tapas serán susceptibles de presentar parejas de orificios pasantes (12) a los que se vincularán cordones o cuerdas (13) que determinen asas de agarre manual de los extremos de la caja-estuche. As stated previously, the semi-covers will be capable of presenting pairs of through holes (12) to which cords or ropes (13) that determine manual grip handles of the ends of the case-case will be linked.
