Description

Caja apilable de fácil acceso.Stackable box with easy access.

Object of the invention

La presente invención se refiere a una caja apilable, concretamente a una caja de cartón, que ha sido concebida y estructurada en orden a ofrecer una óptima estabilidad en situación de apilamiento, así como una fácil accesibilidad a los productos alojados en su interior, en la propia posición de apilamiento en el punto de venta, es decir que la caja está prevista también para actuar como expositor frente al consumidor de los productos contenidos en la misma.The present invention relates to a box stackable, specifically to a cardboard box, which has been conceived and structured in order to offer optimum stability in stacking situation, as well as easy accessibility to products housed inside, in the position of stacking at the point of sale, that is to say that the box is also planned to act as an exhibitor in front of the consumer of the products contained in it.

La caja que se preconiza resulta especialmente idónea para el transporte y distribución de productos alimenticios, en particular de cartones de huevos, pero obviamente es utilizable en cualquier otro supuesto práctico en el que se requieran unas prestaciones similares.The box that is recommended is especially ideal for the transport and distribution of food products, in particular of egg cartons, but obviously it is usable in any other practical case in which some are required similar benefits.

La invención se sitúa pues en el ámbito de la industria del cartonaje, y mas concretamente de la fabricación de cajas de cartón comercializables indistintamente en forma de plancha o definitivamente armadas.The invention thus falls within the scope of the cardboard industry, and more specifically the manufacture of cardboard boxes indistinctly in the form of an iron or definitely armed.

Background of the invention

En el ámbito de las cajas de cartón apilables y con independencia de múltiples soluciones para el armado de las mismas, una constante común a todas las cajas de ese tipo es el estar constituidas por un cuerpo prismático rectangular, en el que participa un fondo, dos testeros y dos gualderas, siendo habitualmente la altura de los testeros coincidente con la altura de la propia caja, mientras que es habitual que las gualderas estén rebajadas en altura.In the field of stackable cardboard boxes and regardless of multiple solutions for the assembly of same, a constant common to all boxes of that type is the be constituted by a rectangular prismatic body, in which one fund participates, two testeros and two gualderas, being usually the height of the pockets coinciding with the height of the box itself, while it is usual that the gates are lowered in height.

Para asegurar la estabilidad en el apilamiento, es habitual que al menos en dos de sus paredes laterales, preferentemente en las gualderas, existan pequeñas pestañas o prolongaciones superiores de las que son complementarias escotaduras existentes junto al borde inferior de sus gualderas, de manera que en el apilamiento las citadas pestañas encajan en las respectivas escotaduras.To ensure stacking stability, It is usual that at least two of its side walls, preferably in the gates, there are small tabs or higher extensions than are complementary existing recesses next to the lower edge of their gualderas, of so that in the stacking the mentioned tabs fit the respective recesses.

Esto trae consigo un efecto de machihembrado en el apilamiento entre cajas, que en muchas ocasiones resulta insuficiente, en especial cuando las cajas han de soportar pesos considerables, ya que tales pestañas solo producen una contención lateral en un determinado sentido, resultando inoperantes en sentido opuesto, con lo que una deformación de las mismas hace que el acoplamiento resulte bastante inestable.This brings with it a tongue and groove effect on stacking between boxes, which often results insufficient, especially when the boxes have to bear weights considerable, since such eyelashes only produce a containment lateral in a certain sense, being inoperative in sense opposite, so a deformation of them causes the coupling is quite unstable.

Por otro lado y cuando la caja requiere además de una función expositora, es deseable que tanto sus testeros como sus gualderas estén acusadamente rebajados, para potenciar al máximo la visualización de los productos contenidos en el interior, así como para facilitar la accesibilidad de los mismos, en cualquier posición de la caja sobre la estantería y cuando sobre ella se encuentran apiladas otras cajas, lo que debilita sustancialmente su estructura repercutiendo negativamente en el acoplamiento machihembrado a través de las pestañas y escotaduras a que se ha hecho mención con anterioridad.On the other hand and when the box also requires of an expository function, it is desirable that both their heads and their gates are sharply lowered, to maximize the display of the products contained inside, as well as to facilitate their accessibility, in any position of the box on the shelf and when on it other boxes are stacked, which substantially weakens their structure negatively impacting the coupling tongue and groove through the eyelashes and recesses that have been Mentioned before.

Description of the invention

La caja apilable que la invención propone, presentando amplias aberturas de acceso en sus paredes laterales, es decir tanto en sus gualderas como en sus testeros, que facilitan la accesibilidad visual a su contenido, resolviendo de fo?na plenamente satisfactoria la problemática de la estabilidad en el apilamiento a que se ha hecho mención con anterioridad, asegurando un posicionamiento relativo entre cajas perfectamente estable cuando se encuentran apiladas, e incluso repercutiendo dicho acoplamiento en la resistencia mecánica final de sus paredes laterales, como se verá mas adelante.The stackable box that the invention proposes, presenting wide access openings in its side walls, it is say both in their gates and in their heads, which facilitate the visual accessibility to its content, resolving fully satisfactory the problem of stacking stability at that has been mentioned before, ensuring a Relative positioning between boxes perfectly stable when they find stacked, and even impacting said coupling on the final mechanical resistance of its side walls, as will be seen later.

Para ello y de forma mas concreta, la caja que la invención propone centra sus características en el hecho de que sus gualderas son ligeramente convergentes en sentido ascendente, de manera que la caja adopta un perfil a su vez ligeramente trapecial isoscélico, de manera que sus pestañas de acoplamiento machihembrado en el apilamiento entre cajas, en lugar de ser a escotaduras laterales e inferiores de las propias gualderas, se acoplan en orificios del fondo o base de la caja inmediatamente superior, situados inmediatamente por dentro de la línea de abatimiento de las gualderas y que consecuentemente retienen a las pestañas frente a cualquier tendencia al desplazamiento horizontal, tanto en sentido longitudinal como en sentido transversal.For this and more specifically, the box that the invention proposes focuses its characteristics on the fact that their gates are slightly convergent upwards, so that the box adopts a slightly turn profile isoscelic trapecial, so that its coupling tabs tongue and groove in stacking between boxes, instead of being a side and bottom recesses of the gualderas themselves, it they fit into holes in the bottom or base of the box immediately superior, located immediately inside the line of dejection of the gualderas and consequently retain the tabs against any tendency to horizontal displacement, both longitudinally and transversely.

De esta manera no solo se consigue una mayor estabilidad en el apilamiento entre cajas, sino que además cada caja constituye a través de su fondo un nexo de unión, en el que los cuatro vértices de la caja inmediatamente inferior, rigidizan a ésta última a nivel de su embocadura.In this way, not only is greater Stacking stability between boxes, but also each box it constitutes through its bottom a union nexus, in which the four vertices of the box immediately below, stiffen it last at the level of its mouth.

Como complemento de la estructura descrita se ha previsto que los testeros sean simples, para minimizar la cantidad de material que participa en la caja, mientras que sus gualderas son dobles, abatiéndose la mitad de cada una de ellas hacia el interior de la caja, y contando su borde libre con pestañas que se acoplan al fondo de la caja, pero habiéndose previsto que simultáneamente a este acoplamiento mecánico se lleve a cabo la fijación de las dos partes de la gualdera mediante un adhesivo apropiado, con lo que se consigue potenciar considerablemente la rigidez estructural de dichas gualderas respecto al pandeo.As a complement to the structure described, provided that the testeros are simple, to minimize the amount of material that participates in the box, while its gates are doubles, folding half of each of them inwards of the box, and counting its free edge with tabs that attach to the bottom of the box, but having been expected to simultaneously this mechanical coupling is carried out fixing the two parts of the gualdera by means of an appropriate adhesive, with which manages to significantly strengthen the structural rigidity of these gauges regarding buckling.

Preferred Embodiment of the Invention

A la vista de las figuras reseñadas puede observarse como la caja apilable que la invención propone, como cualquier caja de cartón de este tipo, está constituida a partir de una fondo (1), rectangular, delimitado por líneas de plegado (2) en base a las cuales se establecen los testeros (3) y las gualderas (4) de la caja, abatibles durante el armado de la caja, armado que se lleva a cabo con la colaboración de aletas (5) prolongación de las gualderas (4) y relacionadas con éstas últimas a través de líneas de plegado (6), estando estas aletas (5) destinadas a abatirse sobre la cara interna de los testeros (3) y a fijarse a los mismos mediante adhesivo.In view of the figures outlined you can be observed as the stackable box that the invention proposes, as Any cardboard box of this type is made from a bottom (1), rectangular, delimited by fold lines (2) in base to which the testeros (3) and the gualderas (4) are established of the box, foldable during the assembly of the box, armed that carried out with the collaboration of fins (5) prolongation of gualderas (4) and related to the latter through lines of folded (6), these fins (5) being designed to fold over the inner face of the heads (3) and to be fixed to them by adhesive.

Pues bien, de acuerdo ya con la invención, las citadas aletas (5) presentan el que ha de ser su borde inferior (7) ligeramente inclinado, de manera que en el armado de la caja, transmiten dicha inclinación a las gualderas (6), las cuales resultan ligeramente convergentes en sentido ascendente.Well, according to the invention, the said fins (5) have what must be its lower edge (7) slightly inclined, so that when assembling the box, transmit said inclination to the gates (6), which They are slightly convergent upwards.

De esta manera las clásicas pestañas (8) de acoplamiento machihembrado en el apilamiento entre cajas, en lugar de resultar coplanarias con las gualderas de la caja inmediatamente superior, quedan desfasadas hacia dentro y se acoplan en orificios ranurados (9) operativamente establecidos en el fondo (1) de la caja, dichas pestañas (8) quedan totalmente inmovilizadas en sentido horizontal, como se desprende de la observación de la figura 3.In this way the classic eyelashes (8) of tongue and groove coupling in stacking between boxes, instead if coplanar with the boxes in the box immediately upper, they are out of phase inwards and are coupled in holes grooves (9) operatively established in the bottom (1) of the box, said tabs (8) are completely immobilized in the direction horizontal, as can be seen from the observation in figure 3.

Se ha previsto además que en el troquelado de la plancha constitutiva de la caja, los orificios (9) se obtengan mediante un corte en "U" que afecta a su lado interno y a sus dos lados extremos, de manera que en el corte se define una lengüeta (10) proyectada hacia abajo, que colabora también mejorando la estabilidad del acoplamiento.It is also planned that in the die cutting of the constitutive plate of the box, the holes (9) are obtained through a "U" cut that affects your inner side and its two extreme sides, so that in the cut a tongue is defined (10) projected downward, which also helps improve the coupling stability.

Como se observa en la figura 2, los testeros (3) son de escasa altura, para minimizar el consumo de material, es decir el consumo de cartón, y las gualderas (4) presentan una altura similar, siendo dobles en la zona central y rebajada donde su mitad terminal (11) se abate sobre la cara interna de la doble pared que configura, duplicando el espesor efectivo de la misma y fijándose ambas mitades mediante un adhesivo situado entre ellas, así como mediante pestañas (12) similares a las pestañas (8) de sus zonas extremas, enchufables en orificios (13) alineados con los orificios (9) anteriormente citados.As seen in figure 2, the testeros (3) They are of low height, to minimize material consumption, it is say the consumption of cardboard, and the gates (4) have a height similar, being double in the central area and lowered where its half terminal (11) is lowered on the inner side of the double wall that set up, doubling the effective thickness of it and setting both halves by means of an adhesive located between them, as well as by means of tabs (12) similar to the tabs (8) of their areas ends, pluggable in holes (13) aligned with the holes (9) above.

Se consigue de esta manera, como se observa especialmente en la figura 3, una caja apilable de óptima estabilidad en situación de apilamiento, con amplias aberturas tanto en sus testeros como en sus gualderas, que ofrece una óptima accesibilidad a su interior cuando actúa como expositor, con un mínimo consumo de material y con una óptima resistencia mecánica, caja que generalmente puede ser complementada con cualquier tapa convencional apropiada, si así se desea.It is achieved in this way, as observed especially in figure 3, a stackable box of optimal Stacking stability, with wide openings both in their heads as in their gates, which offers an optimal accessibility to its interior when it acts as an exhibitor, with a minimum material consumption and optimum mechanical strength, box that can usually be complemented with any lid appropriate conventional, if desired.
