Description

Caja de cartón decaédrica.Decahedral cardboard box.

Object of the invention

La presente invención se refiere a una caja de cartón, concretamente a una caja decaédrica, es decir provista de diez caras, que sin embargo y a pesar de este número de caras, presenta bases perfectamente rectangulares, de manera que su cuerpo, de configuración caprichosa, se aleja por completo de lo habitual.The present invention relates to a box of cardboard, specifically to a decahedral box, that is to say provided with ten faces, which however and despite this number of faces, it presents perfectly rectangular bases, so that its body, whimsical configuration, moves away completely from what habitual.

Así pues, el objeto de la invención es conseguir una caja que resulte altamente atractiva para el consumidor, sin menoscabo de su resistencia mecánica frente a esfuerzos exteriores, fundamentalmente los debidos a su apilamiento.Thus, the object of the invention is to achieve a box that is highly attractive to the consumer, without undermines its mechanical resistance against external stresses, fundamentally those due to its stacking.

Background of the invention

Dentro de la gran variedad de cajas de cartón existentes en el mercado, que varían estructuralmente en función de su aplicación práctica y otros condicionantes, una caja clásica y de uso totalmente generalizado es aquella constituida mediante un cuerpo laminar y monopieza, en el que mediante troquelado se definen cuatro sectores rectangulares, iguales dos a dos, correspondientes a las paredes laterales de la caja, prolongados cada uno de ellos y a través de líneas de plegado en parejas de solapas que en el armado de la caja van a constituir las bases de la misma, prolongándose además un sector extremo en un aleta para fijación al otro sector extremo, en orden a conseguir la necesaria configuración tubular del cuerpo de la caja, que posteriormente se cerrará mediante las solapas citadas.Within the wide variety of cardboard boxes existing in the market, which vary structurally depending on its practical application and other conditions, a classic box and of totally generalized use is that constituted by a laminar and single piece body, in which by means of die cutting define four rectangular sectors, equal two to two, corresponding to the side walls of the box, prolonged each of them and through folding lines in pairs of flaps that in the assembly of the box will constitute the bases of it, also extending an extreme sector in a fin to fixation to the other extreme sector, in order to get the necessary tubular configuration of the case body, which is subsequently will close using the flaps mentioned.

Se consigue de esta manera una caja de configuración prismático-rectangular, susceptible de variar dimensionalmente en altura, anchura y/o profundidad, pero que mantiene siempre la citada configuración prismática.In this way a box of prismatic-rectangular configuration, susceptible of varying dimensionally in height, width and / or depth, but which always maintains the aforementioned prismatic configuration.

Description of the invention

La caja de cartón que la invención propone, partiendo igualmente de un cuerpo laminar y monopieza con los cuatro sectores anteriormente citados, sus correspondientes parejas de solapas y la aleta extrema de cierre, adopta en posición de armado una configuración muy peculiar, concretamente una configuración tendente al prisma rectangular, pero con sus aristas verticales achaflanadas, concretamente con respectivos chaflanes en forma de ojal, es decir de bordes laterales curvo-convexos, que dan lugar a un chaflán a su vez incluido en un imaginario plano curvo-cóncavo.The cardboard box that the invention proposes, also starting from a laminar body and monopieza with the four sectors mentioned above, their corresponding partners of flaps and the extreme closing flap, adopts in position of armed a very peculiar configuration, specifically a configuration tending to the rectangular prism, but with its edges chamfered verticals, specifically with respective chamfers in eyelet shape, that is to say side edges curved-convex, which give rise to a chamfer in turn included in an imaginary curved-concave plane.

Para ello y de forma mas concreta, dos de los sectores del cuerpo laminar, contrapuestos tras el armado de la caja, se relacionan con las correspondientes solapas a través de dos hendidos o líneas de plegado curvas, unidas por sus extremos y de concavidades enfrentadas, de manera que tras el armado de la caja dichas líneas de plegado van a dar lugar a las citadas aristas achaflanadas que relacionan entre sí cuatro caras laterales, todas ellas esencialmente planas pero delimitadas por bordes curvo-cóncavos.For this and more specifically, two of the sectors of the laminar body, opposed after the assembly of the box, relate to the corresponding flaps through two creases or curved fold lines, joined by their ends and of concavities faced, so that after the assembly of the box said folding lines will give rise to the aforementioned edges chamfered that relate four side faces to each other, all they are essentially flat but bounded by edges curved-concave.

Como complemento de la estructura descrita y al objeto de que las solapas de armado de la caja no interfieran en estos chaflanes del cuerpo, se ha previsto que dichas solapas adopten una configuración trapecial isoscélica, preferentemente con sus lados oblicuos curvos, concretamente con el mismo radio de curvatura que el de las líneas de plegado a las que han de superponerse o adaptarse.As a complement to the structure described and to so that the box's flaps do not interfere with these body chamfers, said flaps are planned adopt an isoscelic trapecial configuration, preferably with its oblique curved sides, specifically with the same radius of curvature than that of the folding lines to which overlap or adapt.

Se consigue de esta manera una caja cuyas seis paredes básicas quedan incluidas en las caras de un imaginario prisma rectangular, pero con la configuración caprichosa derivada del hecho de que sus aristas verticales estén achaflanadas, de acuerdo con lo anteriormente expuesto, determinando otras cuatro caras complementarias, que permiten una mejor y mayor sujeción del producto contenido en la caja.In this way a box is obtained whose six basic walls are included in the faces of an imaginary rectangular prism, but with the whimsical configuration derived of the fact that its vertical edges are chamfered, of according to the above, determining another four complementary faces, which allow a better and greater support of the Product contained in the box.

Preferred Embodiment of the Invention

A la vista de las figuras reseñadas y en especial de la figura 1, puede observarse como la caja que se preconiza está constituida por un cuerpo monopieza (1) en el que mediante troquelado se definen cuatro sectores (2, 3, 4 y 5), en alineación, relacionados entre sí a través de líneas de plegado (6), presentando dos de estos sectores (3-5) idéntica configuración rectangular, mientras que los otros dos (2-4), alternados con los anteriores, adoptan una configuración también tendente al rectángulo pero con sus bordes laterales o libres (7) notablemente curvo-cóncavos.In view of the figures outlined and in special figure 1, can be seen as the box that advocates is constituted by a single piece body (1) in which by means of punching, four sectors are defined (2, 3, 4 and 5), in alignment, related to each other through fold lines (6), presenting two of these sectors (3-5) identical rectangular configuration, while the other two (2-4), alternated with the previous ones, adopt a configuration also tending to the rectangle but with its edges lateral or free (7) notably curved-concave.

El sector extremo (5) se prolonga en una aleta (8), a través de la correspondiente línea de plegado (6'), teniendo dicha aleta la clásica función de transformar el conjunto constituido por los sectores (2, 3, 4 y 5) en un cuerpo tubular, mientras que dichos sectores (2, 3, 4 y 5) se prolongan cada uno de ellos por sus bordes laterales y libres en sendas parejas de solapas (9-9'), abatibles las solapas (9) a través de líneas de plegado (10) rectas, mientras que las solapas (9') se abaten doblemente cada una de ellas, concretamente a través de una primera línea de plegado (11) curva, de concavidad exterior, y una segunda línea de plegado (12) también curva, de concavidad contrapuesta a la anterior, líneas (11 y 12) que se unen por sus extremos (13) definiendo un área (14) en forma de "ojal", que en el armado de la caja y como se observa especialmente en la figura 3, va a dar lugar a un chaflán (14) en correspondencia con cada una de las aristas verticales del cuerpo de la caja cuando ésta está debidamente armada y cerrada.The end sector (5) extends into a fin (8), through the corresponding folding line (6 '), having said fin the classic function of transforming the whole constituted by the sectors (2, 3, 4 and 5) in a tubular body, while said sectors (2, 3, 4 and 5) extend each of they by their lateral edges and free in pairs of lapels (9-9 '), folding flaps (9) through lines folding (10) straight, while the flaps (9 ') fold doubly each of them, specifically through a first bend line (11) curve, with outer concavity, and a second fold line (12) also curved, with concavity opposed to the previous one, lines (11 and 12) that join at their ends (13) defining an area (14) in the form of "eyelet", which in the assembly of the box and as seen especially in figure 3, it will give place to a chamfer (14) in correspondence with each of the vertical edges of the body of the box when it is duly armed and closed.

Para que las solapas (9-9') no interfieran en los citados chaflanes (14) de las aristas verticales del cuerpo de la caja, se ha previsto que dichas solapas adopten una configuración trapecial isoscélica, cuyos bordes laterales (15) serán preferentemente curvo cóncavos, con una curvatura coincidente con las de las líneas de plegado (11 y 12) a las que deben adaptarse.So that the flaps (9-9 ') do not interfere in the aforementioned chamfers (14) of the vertical edges of the body of the box, said flaps are expected to adopt an isoscelic trapezoidal configuration, whose lateral edges (15) they will be preferably concave curved, with a matching curvature with those of the folding lines (11 and 12) to which they must adapt.

Las citadas solapas (9-9') pueden ser de igual amplitud, tal como muestra la figura 1, o pueden ser unas considerablemente mas altas que otras, tal como se ha representado en la figura 3.The aforementioned flaps (9-9 ') they can be of equal amplitude, as shown in figure 1, or they may be considerably higher than others, as is He has depicted in figure 3.

En cualquier caso se consigue que, tras el armado del cuerpo laminar (1), o lo que es lo mismo tras el armado de la caja, ésta adopte una configuración que si bien tiende al prisma rectangular, presenta sus aristas verticales (14) acusadamente achaflanadas y curvo cóncavas, lo que confiere a la caja un aspecto totalmente ajeno a lo que es habitual, presentando la caja bases perfectamente rectangulares, mientras que incorpora ocho paredes laterales, frente a las cuatro convencionales.In any case you get that, after the laminar body assembly (1), or what is the same after assembly of the box, it adopts a configuration that although it tends to rectangular prism, presents its vertical edges (14) sharply chamfered and curved concave, which gives the box looks totally foreign to what is usual, presenting the box perfectly rectangular bases, while incorporating eight side walls, compared to the conventional four.
