Bandeja de cartón para entrega de productos a domicilioCardboard tray for home delivery of products

SECTOR DE LA TÉCNICATECHNICAL SECTOR

La presente invención se refiere a una bandeja de cartón que ha sido especialmente concebida para permitir llevar a cabo la entrega de productos a domicilio, si bien no se descartan otras aplicaciones en las que se requieran de unas prestaciones similares.The present invention refers to a cardboard tray that has been specially conceived to allow home delivery of products, although other applications in which similar features are required are not ruled out.

El objeto de la invención es proporcionar una bandeja estructuralmente sencilla, económica, fácil de armar, pero sumamente segura en virtud de una estructura en la que se definen elementos prominentes en funciones de estructuras “para-golpes”, que protejan la integridad de los objetos contenidos en la bandeja.The object of the invention is to provide a tray that is structurally simple, economical, easy to assemble, but extremely safe by virtue of a structure in which prominent elements are defined as "bumper" structures, which protect the integrity of the objects. contents in the tray.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

En el ámbito de aplicación práctica de la invención se conocen bandejas de cartón automontables, que presentan una configuración prismática abierta en la parte superior, es decir, a modo de caja sin un cierre superior.In the field of practical application of the invention, self-assembling cardboard trays are known, which have a prismatic configuration open at the top, that is, like a box without a top closure.

Esta bandeja de auto-montaje se puede montar directamente a partir de una única lámina doblada, sin tener que realizar ninguna operación adicional, de modo que se proporciona la hoja plegada y opcionalmente, con un encolado en la parte central de la base es posible erigir la bandeja simplemente estirando convenientemente desde los extremos de la caja para que coincidan con las asas.This self-assembly tray can be assembled directly from a single folded sheet, without having to carry out any additional operation, so that the folded sheet is provided and optionally, with a glue in the central part of the base it is possible to erect the tray by simply pulling conveniently from the ends of the box to match the handles.

Una bandeja de este tipo se describe en la patente de invención ES 2529379, de manera que si bien a través de la estructura que se define en tal registro se obtiene una bandeja funcional fácil y rápida de armar en el momento de su utilización, de modo que en situación inoperante presente una estructuración con una ocupación volumétrica mínima, la realidad es que la estructura prismático rectangular abierta superiormente que se obtiene con esta bandeja deja las aristas tanto verticales como horizontales de la bandeja expuestas a golpes, golpes que se transmitirán de forma directa a los objetos contenidos en su seno, con el consecuente riesgo de dañado de éstos que ello supone.A tray of this type is described in the invention patent ES 2529379, so that although through the structure defined in such record a functional tray is obtained that is easy and quick to assemble at the time of use, so that in an inoperative situation presents a structure with a minimum volumetric occupation, the reality is that the prismatic rectangular structure open at the top that is obtained with this tray leaves both the vertical and horizontal edges of the tray exposed to blows, blows that will be transmitted directly to the objects contained within, with the consequent risk of damaging them that this entails.

A mayor abundamiento, en la estructura de la bandeja descrita en la patente de invención ES 2529379 la estructura de los testeros se ve reforzada solo parcialmente mediante unos pequeños sectores en los que se define una doble pared, que no afecta a toda la superficie del testero, en contra de lo que sería deseable.Furthermore, in the structure of the tray described in the invention patent ES 2529379, the structure of the end walls is only partially reinforced by small sectors in which a double wall is defined, which does not affect the entire surface of the end wall. contrary to what would be desirable.

EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION

La bandeja de cartón para entrega de productos a domicilio que se preconiza resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en base a una solución sencilla pero eficaz, ofreciendo una estructura mucho mas segura frente a impactos, al incluir elementos amortiguadores/absorbedores de los golpes en correspondencia con seis de sus ocho aristas, que evitan o reducen sensiblemente la transmisión de los posibles impactos contra dichas aristas al contenido interno de la bandeja.The cardboard tray for home delivery of products that is recommended solves in a fully satisfactory way the aforementioned problems, based on a simple but effective solution, offering a much safer structure against impacts, by including shock-absorbing/absorbing elements. hits in correspondence with six of its eight edges, which avoid or significantly reduce the transmission of possible impacts against said edges to the internal content of the tray.

Para ello, y de forma más concreta, la bandeja de la invención se constituye a partir del desarrollo de una lámina de cartón troquelado en la que se definen un sector central rectangular, determinante del fondo de la bandeja, de cuyos bordes laterales mayores y delimitados por líneas de plegado emergen las correspondientes gualderas de la bandeja, de configuración igualmente rectangular, de cuyos extremos laterales y libres emergen sendos sectores determinantes de los testeros de la bandeja, que presentarán una estructura de doble pared al emerger de ambas caras de ambas gualderas, y que se vinculan al borde menor de la base de la bandeja a partir de un sector intermedio que relaciona los testeros de gualderas opuestas y el borde menor del fondo de la bandeja a través de una estructuración en la que se definen tres sectores arqueados y plegables a través de líneas de plegado diagonales intermedias, con la especial particularidad de tanto estos sectores intermedios como los testeros no se vinculan directamente al borde menor del fondo y a los laterales de las gualderas directamente, sino que lo hacen a través de unos sectores rectangulares intermedios delimitados por respectivas líneas de plegado, de escasa anchura que permiten plegar los testeros así como la pieza intermedia que los relaciona con el fondo hacia el interior de la bandeja, definiendo en el armado una pestaña perimetral sobresaliente con respecto al testero de doble pared que finalmente se forma, pestaña que en el armado de la bandeja afecta tanto a las aristas verticales de la bandeja como a la arista inferior de ambos testeros, definiendo un elemento a modo de para-golpes, susceptible de deformarse tanto elástica como plásticamente ante un impacto, evitando que dicho impacto sea transmitido al objeto contenido en el seno de la bandeja.For this, and more specifically, the tray of the invention is constituted from the development of a die-cut cardboard sheet in which a rectangular central sector is defined, determining the bottom of the tray, whose larger and delimited lateral edges Through folding lines, the corresponding tray guides emerge, with an equally rectangular configuration, from whose lateral and free ends emerge two sectors that determine the ends of the tray, which will present a double-walled structure when emerging from both sides of both guides, and that are linked to the lower edge of the base of the tray from an intermediate sector that connects the heads of opposite gussets and the lower edge of the bottom of the tray through a structure in which three arched and foldable sectors are defined through intermediate diagonal folding lines, with the special peculiarity of both these intermediate sectors and the front ones are linked directly to the lower edge of the bottom and to the sides of the gussets directly, rather they do so through intermediate rectangular sectors delimited by respective folding lines, which are narrow and allow the front ends to be folded as well as the intermediate piece that relates them with the bottom towards the inside of the tray, defining a flange in the assembly protruding perimeter with respect to the double wall head that is finally formed, a flange that in the assembly of the tray affects both the vertical edges of the tray and the lower edge of both ends, defining an element as a bumper, capable of deforming both elastically and plastically on impact, preventing said impact from being transmitted to the object contained within the tray.

En cuanto a la estabilización de la bandeja en su armado, cabe señalar que dos de los testeros dispondrán en su zona media de una ventana a modo de asidero, mientras que los otros dos testeros complementarios en dicha zona presentarán un troquelado complementario pero que no afecta a su borde superior, de modo que este troquelado pueda plegarse hacia el interior a través de la comentada ventana del testero complementario y así estabilizar el conjunto que, como se ha dicho, en dicha zona de los testeros presentará una estructura de doble pared que afecta a todo el ancho del testero.As for the stabilization of the tray in its assembly, it should be noted that two of the ends will have a window in their middle area as a handle, while the other two complementary ends in said area will have a complementary die-cut but that does not affect to its upper edge, so that this die-cut can be folded inwards through the mentioned window of the complementary headwall and thus stabilize the assembly which, as has been said, in said area of the headwalls will present a double-walled structure that affects to the full width of the headwall.

Para mayor estabilidad, en correspondencia con la zona intermedia e inferior de plegado de los testeros con respecto a la pieza intermedia vinculada al borde menor del fondo de la bandeja se pueden incluir respectivas y contrapuestas ranuras y pestañas complementarias que encajen entre sí dando una mayor estabilidad al conjunto.For greater stability, in correspondence with the intermediate and lower folding area of the ends with respect to the intermediate piece linked to the lower edge of the bottom of the tray, respective and opposing slots and complementary tabs can be included that fit together giving greater stability. to the set.

Se consigue de esta manera una bandeja estructuralmente sencilla pero sumamente resistente frente a posibles impactos contra la misma, segura y fácil y rápida de armar y desarmar.In this way, a structurally simple but extremely resistant tray is achieved against possible impacts against it, safe and easy and quick to assemble and disassemble.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION

A la vista de las figuras reseñadas, puede observarse como la bandeja de cartón para entrega de productos a domicilio de la invención se constituye a partir de una lámina de cartón troquelada, en la que participa un sector central rectangular determinante del fondo (1) de la bandeja, de cuyos bordes laterales mayores (2) emergen delimitados por líneas de plegado sectores igualmente rectangulares determinantes de las gualderas (3).In view of the figures outlined, it can be seen how the cardboard tray for home delivery of products of the invention is constituted from a die-cut cardboard sheet, in which a central rectangular sector that determines the bottom (1) of the tray participates. the tray, from whose larger lateral edges (2) emerge, delimited by folding lines, equally rectangular sectors that determine the skirting (3).

Paralelamente, de los extremos laterales de ambas gualderas (2) emergen respectivos sectores determinantes de los testeros (4), testeros que se vinculan al borde menor del fondo (1) de la bandeja a través de unos sectores intermedios (5) con una estructuración en la que se definen tres sectores arqueados y plegables a través de líneas de plegado diagonales intermedias (6).At the same time, respective determining sectors of the ends (4) emerge from the lateral ends of both sides (2), ends that are linked to the lower edge of the bottom (1) of the tray through intermediate sectors (5) with a structuring in which three arched and foldable sectors are defined through intermediate diagonal fold lines (6).

Pues bien, de acuerdo con la esencia de la invención se ha previsto que los sectores intermedios (5), así como los testeros (4) no se vinculen directamente al borde menor del fondo (1) y a los laterales de las gualderas (3), sino que lo hacen a través de unos sectores rectangulares intermedios (7-7’), alineados entre sí, con una anchura del orden de 30 milímetros, si bien esta medida podría variar en función del grado de protección perseguido, de manera que a través de estos sectores rectangulares intermedios (7-7’) es posible plegar y desplazar los testeros así como la pieza intermedia que los relaciona con el fondo hacia el interior de la bandeja, definiendo en el armado una pestaña perimetral sobresaliente con respecto al testero que finalmente se forma, es decir una pestaña que sobresale una longitud del orden de 30 milímetros, definiendo un elemento a modo de para-golpes, susceptible de deformarse tanto elástica como plásticamente ante un impacto, evitando que dicho impacto sea transmitido al objeto contenido en el seno de la bandeja. Well, in accordance with the essence of the invention, it has been foreseen that the intermediate sectors (5), as well as the ends (4) are not directly linked to the lower edge of the bottom (1) and to the sides of the gussets (3). , but they do so through intermediate rectangular sectors (7-7'), aligned with each other, with a width of the order of 30 millimeters, although this measure could vary depending on the degree of protection pursued, so that through these intermediate rectangular sectors (7-7') it is possible to fold and move the ends as well as the intermediate piece that relates them to the bottom towards the interior of the tray, defining in the assembly a perimeter flange protruding with respect to the end that finally it is formed, that is, a tab that protrudes a length of the order of 30 millimeters, defining an element in the form of a bumper, capable of deforming both elastically and plastically on impact, preventing said impact from being trans nsmitted to the object contained within the tray.

De acuerdo con otra de las características de la invención, se ha previsto que los sectores determinantes de los testeros (4) presenten una anchura acorde a la anchura del fondo (1) de la bandeja, es decir una anchura acorde a la anchura de su borde menor, lo que permite obtener una bandeja con unos testeros en los que participa una doble pared que afecta a toda la superficie del testero, en contra de lo que sucede en otras bandejas que dicha doble pared solo afecta a un porcentaje del testero, con la menor resistencia estructural que ello supone.According to another of the characteristics of the invention, it has been provided that the determining sectors of the ends (4) have a width according to the width of the bottom (1) of the tray, that is, a width according to the width of its minor edge, which makes it possible to obtain a tray with some ends in which a double wall participates that affects the entire surface of the end, contrary to what happens in other trays where said double wall only affects a percentage of the end, with the lower structural resistance that this entails.

Tal y como se puede observar en la figura 2, la bandeja se apilará/suministrará con los testeros (4), los sectores intermedios (5) y los sectores rectangulares intermedios (7’-7) plegados sobre las gualderas (3) y el fondo (1) respectivamente, para que así la bandeja presente una estructuración laminar con unas dimensiones en planta menores, fácilmente apilable, de modo que en el momento de proceder al armado y de acuerdo con las figuras 3 a 5, se desplegarán los testeros (4) con respecto a los sectores rectangulares intermedios (7’) mientras que los sectores intermedios (5) se plegarán a través de sus líneas de plegado diagonales intermedias (6) de manera que ambos testeros (4) queden superpuestos formando una doble pared, mientras que los sectores rectangulares intermedios (7-7’) definan una pestaña prominente que afecta tanto a las aristas verticales de la bandeja como a la arista inferior de ambos testeros, en funciones de para-golpes, tal como se observa en la figura 5.As can be seen in figure 2, the tray will be stacked/supplied with the ends (4), the intermediate sectors (5) and the intermediate rectangular sectors (7'-7) folded over the skirting (3) and the bottom (1) respectively, so that the tray has a laminar structure with smaller plan dimensions, easily stackable, so that at the time of assembly and in accordance with figures 3 to 5, the ends will be unfolded ( 4) with respect to the intermediate rectangular sectors (7') while the intermediate sectors (5) will be folded through their intermediate diagonal folding lines (6) so that both ends (4) are superimposed forming a double wall, while the intermediate rectangular sectors (7-7') define a prominent flange that affects both the vertical edges of the tray and the lower edge of both ends, acting as bumpers, as shown in figure 5 .

Para estabilizar la bandeja, se ha previsto que dos de los testeros (4) dispongan en su zona media superior de una ventana a modo de asidero (8), mientras que los otros dos testeros (4) complementarios en dicha zona presentarán un troquelado complementario (9) pero que no afecta a su borde superior, de modo que este troquelado define un sector que puede plegarse hacia el interior a través de la comentada ventana del testero complementario y así estabilizar el conjunto.To stabilize the tray, it has been planned that two of the ends (4) have a window in their upper middle area as a handle (8), while the other two complementary ends (4) in said area will have a complementary die-cut (9) but that does not affect its upper edge, so that this die-cut defines a sector that can be folded inwards through the mentioned window of the complementary headwall and thus stabilize the assembly.

A mayor abundamiento, en correspondencia con la zona intermedia e inferior de plegado de los testeros (4) con respecto a la pieza intermedia (5) vinculada al borde menor del fondo (1) de la bandeja se incluyen respectivas y contrapuestas ranuras (10) y pestañas (11) complementarias que en el armado de la bandeja encajen entre sí dando una mayor estabilidad al conjunto. Furthermore, in correspondence with the intermediate and lower folding area of the ends (4) with respect to the intermediate piece (5) linked to the lower edge of the bottom (1) of the tray, respective and opposing slots (10) are included and complementary tabs (11) that fit together when assembling the tray, giving the assembly greater stability.
