ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Existen diversos desarrollos relativos a bandejas de cartón compacto obtenidas a partir de una única pieza o de varias piezas troqueladas que, convenientemente plegadas y adheridas, conforman un conjunto destinado al transporte de productos, en especial productos perecederos tales como frutas, contemplándose de modo general en estas bandejas Ia incorporación de medios de encastre que facilitan su superposición apilada.There are several developments related to compact cardboard trays obtained from a single piece or from several stamped pieces that, conveniently folded and attached, form a set for the transport of products, especially perishable products such as fruits, generally contemplated in these trays the incorporation of insertion means that facilitate their stacked overlap.
Más concretamente puede observarse que Ia patente de invenciónMore specifically, it can be seen that the invention patent
EP 1 184 289, perteneciente al mismo solicitante de Ia presente invención, se refiere a una bandeja apilable para el transporte de fruta y productos hortícolas, que se conforma a partir de un único bloque o a partir de cinco piezas troqueladas independientes que forman una base, unas paredes laterales mayores y unas paredes laterales menores o testeros, conformándose los testeros con una doble pared cuya pared exterior consiste en una extensión lateral de Ia pared lateral mayor que se adhiere sobre Ia pared interna del testero.EP 1 184 289, belonging to the same applicant of the present invention, refers to a stackable tray for the transport of fruit and horticultural products, which is formed from a single block or from five independent stamped pieces that form a base, some major side walls and some minor side walls or front walls, the ends being formed with a double wall whose outer wall consists in a lateral extension of the greater lateral wall that adheres on the internal wall of the tester.
Complementariamente se contempla que Ia pared interna del testero disponga de una serie de sectores que se prolongan lateralmente y que convenientemente plegados configuren unas columnas o refuerzos de esquina que confieren a Ia bandeja una mayor resistencia al apilamiento.In addition, it is contemplated that the inner wall of the tester has a series of sectors that extend laterally and that conveniently folded form some columns or corner reinforcements that give the tray greater stacking resistance.
Asimismo dicha bandeja incorpora en el borde superior de los testeros y paredes laterales mayores unos salientes que se insertan en aberturas previstas en el fondo de Ia bandeja superiormente dispuesta facilitando Ia estabilidad posicional en Ia superposición apilada de bandejas.Likewise, said tray incorporates on the upper edge of the heads and larger side walls some projections that are inserted in openings provided in the bottom of the upper disposed tray facilitating positional stability in the stacked tray overlay.
Por otro lado en los testeros de Ia bandeja resulta común Ia incorporación de unos vaciados que permiten Ia introducción de las manos para sujeción y traslado de Ia bandeja.On the other hand, the incorporation of some emptyings that allow the introduction of the hands to hold and transfer the tray is common in the tray heads.
Generalmente este tipo de bandejas se conciben con grandes dimensiones para albergar frutas de cierto tamaño que permanecen en su interior durante su transporte y exposición. En el caso de frutas de tamaño más pequeño, tales como fresas, resulta común el empleo de otro tipo de cajas, cajas de madera, para su almacenamiento y transporte, que pueden contener del orden de 1 o 2 Kg de estos productos que son trasladados por el consumidor en Ia propia caja de madera una vez adquiridos.Generally these types of trays are conceived with large dimensions to house fruits of a certain size that remain inside during transport and exhibition. In the case of fruits of smaller size, such as strawberries, it is common to use other types of boxes, wooden boxes, for storage and transport, which may contain the order of 1 or 2 Kg of these products that are transferred by the consumer in the own wooden box once purchased.
Resulta común Ia necesidad de proteger estos productos, en especial durante su transporte, por Io que en ocasiones se recurre al empleo de una malla protectora que cubre Ia caja de madera y que se encuentra clavada o grapada en sus laterales. DESCRIPCIÓN DE LA INVENCIÓNIt is common the need to protect these products, especially during transport, so that sometimes the use of a protective mesh that covers the wooden box and that is nailed or stapled on its sides. DESCRIPTION OF THE INVENTION
La bandeja apilable de cartón compacto que constituye el objeto de esta invención ofrece una solución para el transporte, almacenamiento y exposición de productos tales como frutas, como alternativa al empleo de cajas de madera, y asimismo facilita Ia protección de los productos contenidos en su interior, resultando de aplicación para cualquier tamaño de bandeja y para el transporte de cualquier producto.The stackable compact cardboard tray that is the object of this invention offers a solution for the transport, storage and exhibition of products such as fruits, as an alternative to the use of wooden boxes, and also facilitates the protection of the products contained inside , resulting from application for any tray size and for the transport of any product.
Más concretamente Ia bandeja apilable de cartón compacto se concibe con una configuración tal, que permite Ia adaptación de una lámina de especial configuración como medio cobertor para Ia protección de los productos albergados en su interior.More specifically, the stackable compact cardboard tray is conceived with such a configuration, which allows the adaptation of a sheet of special configuration as a cover means for the protection of the products housed inside.
En este sentido se ha previsto que Ia bandeja sea del tipo de las que se configuran de modo general a partir de una base, paredes laterales mayores y paredes laterales menores o testeros, siendo estos testeros de doble pared.In this sense, it has been foreseen that the tray is of the type that is generally configured from a base, major side walls and minor side walls or pockets, these double wall berths.
La lámina protectora muestra una configuración esencialmente coincidente a Ia mostrada por Ia base de Ia bandeja y adicionalmente dispone de medios de acoplamiento, que preferentemente consistirán en unas solapas que se prolongan desde sus lados menores destinados a su acoplamiento en unas pestañas interiores definidas en los testeros.The protective sheet shows an essentially coincident configuration to that shown by the base of the tray and additionally has coupling means, which preferably will consist of flaps that extend from its smaller sides intended for coupling in interior flanges defined in the heads .
Como solución preferente se ha previsto que los testeros dispongan de al menos un vaciado en su pared externa y al menos un troquelado practicado en su pared interna enfrentado a dicho vaciado en el que se define Ia mencionada pestaña interior.As a preferred solution, it is provided that the testers have at least one recess in their outer wall and at least one die cut in their inner wall facing said recess in which the said inner flange is defined.
En una primera realización se contempla que Ia pestaña interior sobresalga interiormente en los troquelados practicados en las paredes internas de cada uno de los testeros y que las solapas de Ia lámina protectora disponga de unas aberturas y de un sector externo en el que se encuentra una línea de corte en U. En Ia posición de acoplamiento de Ia lámina protectora sobre Ia bandeja, con las solapas plegadas, dicho sector externo se pliega a su vez hacia el interior de Ia bandeja sobrepasando a Ia pestaña interior del testero, Ia cual queda encajada en Ia abertura de Ia solapa.In a first embodiment it is contemplated that the inner flange it protrudes internally in the die cuttings made in the internal walls of each of the heads and that the flaps of the protective sheet have openings and an external sector in which a U-cut line is located. In the coupling position. of the protective sheet on the tray, with the flaps folded, said external sector folds in turn towards the inside of the tray exceeding the inner flange of the tester, which is embedded in the opening of the flap.
Para esta realización se ha previsto que el vaciado de Ia pared externa del testero incorpore un amplio rebaje de geometría preferentemente coincidente a Ia mostrada por el borde perimetral de Ia solapa, para que esta solapa, en Ia posición de acoplamiento de Ia lámina protectora sobre Ia bandeja, quede en disposición coplanaria con Ia pared externa del testero y por tanto integrada en Ia bandeja.For this embodiment, it has been provided that the emptying of the outer wall of the tester incorporates a wide recess of geometry preferably coinciding with that shown by the perimeter edge of the flap, so that this flap, in the coupling position of the protective sheet on the tray, is in coplanar arrangement with the outer wall of the tester and therefore integrated in the tray.
En una segunda realización de Ia invención se propone que el troquelado de Ia pared interna del testero coincida en su forma con el vaciado de Ia pared externa del testero y que Ia pestaña interior definida en Ia pared interna sobresalga superiormente en dicho troquelado.In a second embodiment of the invention it is proposed that the punching of the inner wall of the tester coincides in its shape with the emptying of the outer wall of the tester and that the inner flange defined in the inner wall protrudes superiorly in said die cutting.
Para esta realización se contempla una segunda configuración de Ia lámina protectora, Ia cual cuenta con al menos una solapa en cada uno de sus lados menores, preferentemente dos, en cualquier caso en número coincidente con los troquelados, en cada una de las cuales se observa una línea de corte en U que definen una pestaña exterior. Desde los extremos de dicha pestaña exterior parten unas líneas de plegado que delimitan un sector exterior de Ia solapa, el cual se introduce a través del troquelado y vaciado plegándose a continuación hacia abajo acoplando así Ia lámina sobre Ia bandeja. Asimismo Ia pestaña exterior de Ia solapa se pliega quedando dispuesta superiormente, enfrentada y en contacto con Ia pestaña interior, definiendo tras su plegado una abertura a través de Ia que sobresale Ia pestaña interior.For this embodiment, a second configuration of the protective foil is contemplated, which has at least one flap on each of its smaller sides, preferably two, in any case in a number coinciding with the die cuts, in each of which it is observed a U-cut line that defines an outer flange. From the ends of said outer flange, some folding lines that delimit an outer sector of the flap, which is introduced through the die cut and emptied, are then folded down, thus coupling the sheet onto the tray. Likewise, the outer flange of the flap is folded being arranged superiorly, facing and in contact with the inner flange, defining after its folding an opening through which the Ia protrudes inner tab
En una tercera realización se contempla que Ia pestaña interior se prolongue desde un sector inferior perteneciente a Ia pared interna del testero que es visible a través del vaciado de Ia pared externa del testero. Dicho sector inferior muestra una forma y dimensión coincidente con el sector exterior de Ia solapa, de tal modo que al introducir Ia solapa a través del troquelado, el sector exterior de Ia solapa se pliega alojándose en el vaciado de Ia pared externa, en disposición enfrentado y en contacto con el sector inferior antes descrito, quedando por tanto Ia solapa integrada en Ia pared externa del testero.In a third embodiment it is contemplated that the inner flange is extended from a lower sector belonging to the inner wall of the tester that is visible through the emptying of the outer wall of the tester. Said lower sector shows a shape and dimension coinciding with the outer sector of the flap, so that when the flap is introduced through the die cut, the outer sector of the flap is folded by being housed in the emptying of the outer wall, in opposite arrangement. and in contact with the lower sector described above, leaving therefore the flap integrated in the outer wall of the tester.
En esta situación en Ia que Ia lámina protectora está acoplada en Ia bandeja, el espacio libre disponible en los vaciados de las paredes externas de los testeros permite Ia introducción de las manos para facilitar el transporte de Ia bandeja.In this situation in which the protective sheet is coupled in the tray, the free space available in the emptyings of the external walls of the heads allows the introduction of the hands to facilitate the transport of the tray.
En una cuarta realización, como alternativa a las soluciones descritas se contempla que, manteniendo Ia misma configuración de Ia lámina protectora, Ia denominada pestaña interior no se encuentre en un troquelado, sino que se prolongue superiormente desde el borde de Ia pared interna del testero, quedando Ia lámina protectora encajada sobre dichas pestañas por medio de sus aberturas y por tanto Ia lámina protectora cubriendo el borde superior de Ia bandeja.In a fourth embodiment, as an alternative to the described solutions, it is contemplated that, while maintaining the same configuration of the protective sheet, the so-called inner flange is not in a die cut, but is prolonged superiorly from the edge of the inner wall of the tester, the protective sheet being fitted on said tabs by means of their openings and therefore the protective sheet covering the upper edge of the tray.
Esta última solución resulta especialmente útil en el caso de que el borde superior de mayor extensión de las paredes laterales de Ia bandeja coincida aproximadamente en altura con Ia altura correspondiente al borde superior del testero, ya que en esta situación Ia lámina protectora cubre Ia bandeja totalmente evitando Ia salida de productos por los laterales. En cualquier caso y para Ia solución en Ia que el borde superior de mayor extensión de las paredes laterales de Ia bandeja sea de altura inferior aThis last solution is especially useful in the case that the upper edge of greater extension of the side walls of the tray coincides approximately in height with the height corresponding to the upper edge of the tester, since in this situation the protective sheet completely covers the tray avoiding the exit of products from the sides. In any case and for the solution in which the upper edge of greater extension of the side walls of the tray is less than
Ia altura correspondiente al borde superior del testero, se contempla que Ia lámina protectora esté dotada de unas amplias solapas laterales que cubran parcial o totalmente el rebaje definido en las paredes laterales de Ia bandeja.The height corresponding to the upper edge of the tester, it is contemplated that the protective sheet is provided with ample lateral flaps that partially or totally cover the recess defined in the side walls of the tray.
Para todas las realizaciones descritas se ha previsto de modo general que Ia pestaña interior muestre una configuración trapecial invertida, con su base mayor de dimensión ligeramente superior a Ia anchura de Ia abertura de Ia solapa de Ia lámina protectora, para de esta forma favorecer el acoplamiento de dicha abertura sobre Ia pestaña interior estableciendo una posición de fijación de Ia lámina protectora sobre Ia bandeja que evita su salida accidental.For all the described embodiments, it is generally provided that the inner flange shows an inverted trapezoidal configuration, with its larger base slightly larger than the width of the opening of the flap of the protective sheet, in order to favor coupling of said opening on the inner flange establishing a position for fixing the protective sheet on the tray that prevents its accidental exit.

La bandeja apilable de cartón compacto (1 ) es del tipo de las que se configuran a partir de una base (20), paredes laterales mayores (2) y paredes laterales menores o testeros (3), y destaca principalmente por Ia incorporación de una lámina protectora (19, 19'), que en cualquiera de las dos realizaciones representadas en las figuras 2 y 5 muestra una configuración esencialmente coincidente a Ia mostrada por Ia base (20) de Ia bandeja (1) y adicionalmente dispone de medios de acoplamiento (10, 10') que convenientemente plegados sobre Ia bandeja (1 ) establecen Ia vinculación deThe stackable compact cardboard tray (1) is of the type that is configured from a base (20), major side walls (2) and minor side walls or front walls (3), and stands out mainly for the incorporation of a protective sheet (19, 19 '), which in any of the two embodiments represented in Figures 2 and 5 shows an essentially coincident configuration to that shown by the base (20) of the tray (1) and additionally has coupling means (10, 10 ') that conveniently folded on the tray (1) establish the bonding of
Ia lámina protectora (19, 19') con Ia bandeja (1) protegiendo de esta forma los productos albergados en su interior.The protective sheet (19, 19 ') with the tray (1) thus protecting the products housed inside.
Los testeros (3) consisten preferentemente en una doble pared formada por una pared externa (5) y una pared interna (4), encontrándose definida en Ia pared interna (4) al menos una pestaña interior (8, 8', 8") sobre Ia que se adaptan los medios de acoplamiento (10, 10') de Ia lámina protectora (19, 19') para establecer el cierre de Ia bandeja (1).The testers (3) preferably consist of a double wall formed by an external wall (5) and an internal wall (4), being defined in the internal wall (4) at least one inner flange (8, 8 ', 8 ") on which the coupling means (10, 10 ') of the protective sheet (19, 19') are adapted to establish the closure of the tray (1).
En las figuras 1 , 4 y 7 correspondientes a distintas realizaciones de Ia bandeja (1), se observa que en Ia pared externa (5) se encuentra definido un vaciado (6, 6', 6") y Ia pared interna (4) está dotada de un troquelado (9, 9', 9"), situado en correspondencia con el vaciado (6, 6', 6"), en el que sobresale Ia pestaña interior (8, 8' ).In Figures 1, 4 and 7 corresponding to different embodiments of the tray (1), it is observed that in the external wall (5) a recess (6, 6 ', 6 ") and the internal wall (4) are defined It is equipped with a die cut (9, 9 ', 9 "), located in correspondence with the emptying (6, 6', 6"), in which the inner flange (8, 8 ') protrudes.
Más concretamente en una primera realización mostrada en Ia figura 1 Ia pestaña interior (8) sobresale ¡nferiormente en el interior del troquelado (9) de Ia pared interna (4), en cuyo caso Ia lámina protectora (19), representada en Ia figura 2, cuenta como medios de acoplamiento (10, 10') con unas solapas (10), coincidentes en número con las pestañas interiores (8), que se prolongan desde sus lados menores y que muestran una abertura (21) y un sector extemo (22) dotado de una línea de corte en U (23) que se pliega interiormente sobrepasando a Ia pestaña interior (8), Ia cual queda encajada en Ia abertura (21) de Ia solapa (10), tal y como se observa en Ia figura 3.More specifically in a first embodiment shown in Figure 1, the inner flange (8) protrudes inferiorly inside the die (9) of the inner wall (4), in which case the protective sheet (19), represented in the figure 2, counts as coupling means (10, 10 ') with flaps (10), coinciding in number with the inner flanges (8), which extend from its minor sides and show an opening (21) and an external sector (22) provided with a U-cut line (23) that folds inside exceeding the inner flange (8), Which is embedded in the opening (21) of the flap (10), as seen in Figure 3.
En una segunda realización representada en Ia figura 4, Ia pestaña interior (8') sobresale superiormente en el troquelado (9') y Ia lámina protectora (19'), que aparece representada en Ia figura 5, cuenta como medios de acoplamiento (10, 10!) con al menos una solapa (10!) en sus lados menores que muestra una línea de corte en U (11) que definen una pestaña exterior (12), de cuyos extremos parten unas líneas de plegado que delimitan un sector exterior (13) de Ia solapa (10'), el cual penetra a través del vaciado (6') de Ia pared extema (5) del testero plegándose hacia abajo, quedando Ia pestaña exterior (12) en posición superior, enfrentada y en contacto con Ia pestaña interior (8'), tal y como se observa en Ia figura 6, sobresaliendo ésta última por una abertura (14) definida en Ia solapa (10') por Ia línea de corte en U (11).In a second embodiment represented in Figure 4, the inner flange (8 ') protrudes superiorly in the die cut (9') and the protective sheet (19 '), which is represented in Figure 5, counts as coupling means (10 , 10 ! ) With at least one flap (10 ! ) On its smaller sides showing a U-cut line (11) defining an outer flange (12), from whose ends split fold lines that delimit an outer sector (13) of the flap (10 '), which penetrates through the emptying (6') of the outer wall (5) of the tester folding down, leaving the outer flange (12) in a superior position, facing and in contact with the inner flange (8 '), as seen in Figure 6, the latter protruding through an opening (14) defined in the flap (10') by the U-cut line (11).
Como solución alternativa a Ia mostrada en Ia figura 4, en Ia figuraAs an alternative solution to that shown in Figure 4, in Figure
7 se representa una tercera realización de Ia invención en Ia que se observa a través del vaciado (6") de Ia pared externa (5) del testero (3), Ia pestaña interior (8') y adicionalmente un sector inferior (15) perteneciente a Ia pared interna (4) del testero (3) que muestra una forma y dimensión coincidente al sector exterior (13) de Ia solapa (10'), sector exterior (13) que se pliega quedando alojado en el vaciado (6"), enfrentado y en contacto con dicho sector inferior (15) , tal y como se aprecia en Ia figura 8.7 represents a third embodiment of the invention in which it is observed through the emptying (6 ") of the outer wall (5) of the tester (3), the inner flange (8 ') and additionally a lower sector (15) pertaining to the inner wall (4) of the tester (3) that shows a shape and dimension coinciding with the outer sector (13) of the flap (10 '), outer sector (13) that folds being lodged in the hollow (6 " ), facing and in contact with said lower sector (15), as can be seen in Figure 8.
En una cuarta realización de Ia invención, representada en Ia figura 9, se mantiene Ia configuración descrita para Ia lámina protectora (19'), y Ia pestaña interior (8") se prolonga desde el borde superior de Ia pared interna (4) del testero (3). En esta situación Ia lámina protectora (19') encaja sobre dichas pestañas interiores (8") por medio de sus aberturas (14), quedando Ia pestaña exterior (12) de Ia solapa (10') enfrentada en correspondencia con Ia pestaña interior (8"), estableciendo el acoplamiento de Ia lámina protectora (19') sobre el borde superior de Ia bandeja (1 ).In a fourth embodiment of the invention, represented in Figure 9, the configuration described for the protective sheet (19 ') is maintained, and the inner flange (8 ") is extended from the upper edge of the inner wall (4) of the testator (3). In this situation, the protective sheet (19 ') fits on said inner flanges (8 ") by means of its openings (14), the outer flange (12) of the flap (10') being left facing in correspondence with the inner flange ( 8 "), establishing the coupling of the protective sheet (19 ') on the upper edge of the tray (1).
La solución representada en Ia figura 9 es de especial utilidad para paredes laterales (2) sin rebajes (24), y por tanto de altura similar a las de los testeros (3), ya que Ia lámina protectora (19') acoplada en el borde superior de Ia bandeja (1) cubriría las paredes laterales (2) evitando Ia salida de los productos. En una solución alternativa en Ia que las paredes laterales (2) dispongan de rebajes (24) se contempla Ia posibilidad de que Ia lámina protectora (19), tal como se representa en Ia figura 1 , pueda estar dotada de unas solapas laterales (25) destinadas a cubrir dichos rebajes (24).The solution represented in Figure 9 is of special use for side walls (2) without recesses (24), and therefore of similar height to those of the heads (3), since the protective sheet (19 ') coupled in the upper edge of the tray (1) would cover the side walls (2) avoiding the exit of the products. In an alternative solution in which the side walls (2) have recesses (24) the possibility that the protective sheet (19), as shown in Figure 1, can be provided with side flaps (25) is contemplated ) intended to cover these recesses (24).
Por otro lado en las figuras 1 , 4, 7 y 9 por ejemplo, se observa que Ia pestaña interior (8, 8', 8") es de configuración preferentemente trapecial invertida con su base mayor de dimensión ligeramente superior a Ia anchura de Ia abertura (21 , 14) de Ia lámina protectora (19, 19') para favorecer de esta manera el acoplamiento de ésta sobre Ia bandeja (1 ).On the other hand, in figures 1, 4, 7 and 9, for example, it can be seen that the inner flange (8, 8 ', 8 ") is preferably inverted with a trapecial configuration with its base larger than a dimension slightly greater than the width of the Ia opening (21, 14) of the protective sheet (19, 19 ') to thus favor the coupling thereof on the tray (1).
Puede observarse asimismo que para las realizaciones descritas, Ia bandeja está dotada de unos salientes (17) en su borde superior concebidos para encajarse en unos aberturas (18) definidas en Ia base de Ia bandeja (1) que se apila superiormente con el fin de garantizar su estabilidad posicional en esta situación. It can also be observed that for the described embodiments, the tray is provided with projections (17) in its upper edge designed to fit into openings (18) defined in the base of the tray (1) that is stacked superiorly in order to guarantee your positional stability in this situation.
