SECTOR DE LA TÉCNICATECHNICAL SECTOR

La presente invención se refiere a una bandeja de cartón o envase de configuración prismático-rectangular abierto superiormente que, partiendo de una estructuración laminar, en la que es fácilmente apilable con otros dispositivos del mismo tipo con una ocupación volumétrica mínima, puede desplegarse y armarse fácilmente en una maniobra rápida y sencilla.The present invention refers to a cardboard tray or container with a prismatic-rectangular configuration open at the top that, starting from a laminar structure, in which it is easily stackable with other devices of the same type with a minimum volumetric occupation, can be easily deployed and assembled. in a quick and easy maneuver.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Si bien se conocen bandejas de cartón o envases de configuración prismático-rectangular alargadas horizontalmente, abiertas superiormente, utilizadas habitualmente para la venta de productos hortofrutícolas y similares, este tipo de bandejas se suministran ya montadas, lo que supone un problema de ocupación volumétrica cuando éstas no están llenas de productos.Although cardboard trays or containers with a horizontally elongated prismatic-rectangular configuration, open at the top, are known, usually used for the sale of fruit and vegetable products and the like, this type of trays are supplied already assembled, which represents a problem of volumetric occupation when they they are not full of products.

EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION

La bandeja de cartón que se preconiza resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en base a una solución sencilla pero eficaz, permitiendo reducir la volumetría de la bandeja en situación inoperante del orden de varias decenas de veces, presentando una estructura en la que su armado se lleva a cabo mediante una maniobra sumamente sencilla y rápida.The cardboard tray that is recommended solves in a fully satisfactory way the above-mentioned problems, based on a simple but effective solution, allowing to reduce the volume of the tray in an inoperative situation in the order of several dozen times, presenting a structure in which its assembly is carried out by means of an extremely simple and fast maneuver.

Para ello, y de forma más concreta, la bandeja de la invención se constituye a partir del desarrollo de una lámina rectangular de cartón en la que, a partir de dos parejas de líneas de plegado paralelas longitudinales y transversales se define el fondo de la bandeja, así como sus paredes laterales mayores y menores, de manera que los sectores extremos que se definen entre estas paredes laterales mayores y menores y que se sitúan en correspondencia con los vértices del rectángulo formado por la lámina de la que se parte, presentan unas líneas de plegado diagonales que emergen hacia fuera desde el punto de confluencia de una y otra línea de plegado transversal y longitudinal, que se interrumpe antes de llegar al extremo de la lámina, de modo que en correspondencia con uno de sus extremos se prolongan en un corte perpendicular al borde lateral mayor de la lámina que se prolonga hasta dicho borde.For this, and more specifically, the tray of the invention is constituted from the development of a rectangular cardboard sheet in which, from two pairs of parallel longitudinal and transverse folding lines, the bottom of the tray is defined. , as well as their major and minor side walls, so that the extreme sectors that are defined between these major and minor side walls and which are located in Correspondence with the vertices of the rectangle formed by the sheet from which it is started, they present diagonal folding lines that emerge outwards from the point of confluence of both transverse and longitudinal folding lines, which is interrupted before reaching the extreme of the sheet, so that in correspondence with one of its ends they extend in a cut perpendicular to the greater lateral edge of the sheet that extends up to said edge.

Pues bien, a partir de esta estructuración, la bandeja se suministrará como un cuerpo aplanado, en el que ambas paredes laterales mayores estarán plegadas sobre el fondo de la bandeja, de modo que los sectores laterales extremos estarán fijados por encolado a las paredes laterales menores, a través de líneas de adhesivo que se extienden desde el citado corte hasta el borde lateral opuesto a dicho corte, lo que da estabilidad a la bandeja en dicha posición, haciendo que el conjunto pueda ser apilado con otras bandejas del mismo tipo con una ocupación volumétrica mínima.Well, from this structuring, the tray will be supplied as a flattened body, in which both major side walls will be folded over the bottom of the tray, so that the extreme side sectors will be fixed by gluing to the smaller side walls. , through adhesive lines that extend from said cut to the opposite side edge to said cut, which gives stability to the tray in said position, making the set can be stacked with other trays of the same type with an occupation minimum volumetric.

Para armar la bandeja simplemente bastará con traccionar de las paredes laterales mayores hacia fuera, hasta que éstas adopten una disposición vertical, de manera que los sectores encolados anteriormente citados conjuntamente con las líneas de plegado diagonales que vinculan los sectores laterales a las paredes laterales mayores y menores provocan que las propias paredes laterales menores tiendan a plegarse hasta adoptar una disposición perpendicularmente al fondo de la bandeja, posición que se estabiliza mediante orificios en los que son enclavables troquelados en forma de arpón previstos en uno y otro sector vinculados al borde lateral de una pared lateral mayor y menor respectivamente.To assemble the tray, it will simply be enough to pull the larger side walls outwards, until they adopt a vertical arrangement, so that the previously mentioned glued sectors together with the diagonal fold lines that link the lateral sectors to the larger side walls and Minors cause the smaller side walls themselves to tend to fold until they adopt an arrangement perpendicular to the bottom of the tray, a position that is stabilized by means of holes in which are interlocking punched in the shape of a harpoon provided in both sectors linked to the lateral edge of a major and minor lateral wall respectively.

De esta forma la bandeja queda perfectamente armada, en una maniobra rápida y sencilla, que apenas supone unos segundos, permitiendo así un ahorro de espacio en situación inoperante sumamente importante.In this way, the tray is perfectly assembled, in a quick and simple maneuver, which only takes a few seconds, thus allowing an extremely important saving of space in an inoperative situation.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION

A la vista de las figuras reseñadas, puede observarse como la bandeja de la invención se constituye a partir del desarrollo de una lámina rectangular de cartón en la que, a partir de dos parejas de líneas de plegado paralelas longitudinales (1) y transversales (2) se define el fondo (3) de la bandeja, así como sus paredes laterales mayores (4) y menores (5).In view of the outlined figures, it can be seen how the tray of the invention is constituted from the development of a rectangular cardboard sheet in which, from two pairs of parallel longitudinal (1) and transverse (2) fold lines ) the bottom (3) of the tray is defined, as well as its larger (4) and smaller (5) side walls.

Pues bien, de acuerdo con la esencia de la invención, se ha previsto que los sectores rectangulares extremos que se definen a partir de las líneas de plegado longitudinales (1) y transversales (2) en correspondencia con los vértices de la lámina que determina la bandeja, presenten unas líneas de plegado diagonales (6) que emergen hacia fuera desde el punto de confluencia de una y otra línea de plegado transversal (2) y longitudinal (1), que se interrumpe antes de llegar al extremo de la lámina, de modo que en correspondencia con uno de sus extremos se prolongan en un corte (7) perpendicular al borde lateral mayor de la lámina que se prolonga hasta dicho borde, definiendo respectivos sectores extremos (8-8’).Well, in accordance with the essence of the invention, it has been envisaged that the extreme rectangular sectors that are defined from the longitudinal (1) and transverse (2) fold lines in correspondence with the vertices of the sheet that determine the tray, have diagonal folding lines (6) that emerge outward from the point of confluence of both transverse (2) and longitudinal (1) folding lines, which is interrupted before reaching the end of the sheet, so that in correspondence with one of its ends they extend in a cut (7) perpendicular to the greater lateral edge of the sheet that extends up to said edge, defining respective end sectors (8-8 ').

A partir de esta estructuración, sobre los bordes laterales de los sectores extremos (8’) se aplicará una línea de adhesivo (9) de modo que la bandeja se suministre como un cuerpo aplanado, el mostrado en la figura 2, en el que ambas paredes laterales mayores (4) estarán plegadas sobre el fondo de la bandeja, de modo que los sectores extremos (8’) estarán fijados por encolado a las paredes laterales menores (5).From this structuring, on the lateral edges of the end sectors (8 ') a line of adhesive (9) will be applied so that the tray is supplied as a body flattened, the one shown in figure 2, in which both major side walls (4) will be folded over the bottom of the tray, so that the end sectors (8 ') will be fixed by gluing to the minor side walls (5) .

Tal y como se puede observar en la figura 3, el simple traccionado hacia fuera de las paredes laterales mayores (4) provoca el abatimiento de las paredes laterales menores (5), de manera que el conjunto se estabiliza en la posición de armado a través de orificios (10) previstos en los sectores extremos (8), en los que son enclavables troquelados en forma de arpón (11) previstos en los sectores extremos (8’).As can be seen in figure 3, the simple pulling out of the larger side walls (4) causes the smaller side walls (5) to collapse, so that the assembly is stabilized in the armed position through of holes (10) provided in the end sectors (8), in which are interlocking punched in the shape of a harpoon (11) provided in the end sectors (8 ').

Solo resta señalar por último que, las paredes laterales menores podrán incorporar troquelados en su zona media superior determinantes de los correspondientes asideros (12) para transporte manual de la bandeja con los productos contenidos en su seno una vez armada la misma. Finally, it only remains to point out that the smaller side walls may incorporate punches in their upper middle area determining the corresponding handles (12) for manual transport of the tray with the products contained within it once it has been assembled.
