Your sale

Background of the invention

En la comercialización de productos perecederos se utilizan cajas de cartón en las que, generalmente a partir de un cuerpo monopieza, se obtienen mediante troquelado y plegado el fondo de la caja, sus gualderas y sus testeros, manteniéndose la caja armada en unos casos mediante "auto-armado", y en otros con la colaboración de adhesivos.In the commercialization of perishable products cardboard boxes are used in which, usually from a single piece body, are obtained by punching and folding the bottom of the box, its gates and its heads, keeping the armed box in some cases by "self-armed", and in others with the collaboration of adhesives

Una de las soluciones más habituales es dotar a las gualderas, en sus bordes laterales, de prolongaciones destinadas a adaptarse a los testeros, siendo estos últimos dobles, de manera que las prolongaciones de las gualderas quedan alojadas en su seno y cada doble testero se estabiliza., bien mediante adhesivo, o bien mediante la existencia en su extremidad libre de una pestaña acoplable en una ranura del fondo de la caja.One of the most common solutions is to provide the gualderas, in their lateral edges, of extensions destined to adapt to the testeros, being these last doubles, so that the extensions of the gates are housed in its bosom and each double tester stabilizes., either by adhesive, or by existence at its tip free from a flange attachable in a groove in the bottom of the box.

Todas las cajas de este tipo presentan como denominador común una configuración prismático-rectangular, y para facilitar la aireación de su contenido es habitual que las gualderas sean de menor altura que los testeros y que en su fondo se establezcan orificios adecuadamente distribuidos, que en ocasiones afectan también a dichas gualderas.All boxes of this type present as common denominator a configuration prismatic-rectangular, and to facilitate the aeration of its contents it is usual that the gates are of lower height than the front and to be established at the bottom properly distributed holes, which sometimes affect also to these boats.

Tanto el transporte como el almacenaje de los productos contenidos en este tipo de cajas, se lleva a cabo de forma paletizada, de manera que el perfecto interacoplamiento de las cajas y especialmente la configuración prismática de las mismas hace que la eficacia de los citados medios de ventilación sea muy escasa ya que cuando las cajas se encuentran apiladas, los testeros de las mismas configuran superficies prácticamente continuas, contactando directamente cada testero con los de las cuatro cajas que le rodean, y haciendo inoperantes los orificios o escotaduras de ventilación interior.Both transport and storage of products contained in this type of boxes, is carried out of palletized form, so that the perfect intercourse of the boxes and especially their prismatic configuration makes the efficiency of the mentioned ventilation means very scarce since when the boxes are stacked, the heads of these configure practically continuous surfaces, directly contacting each testator with those of the four boxes around him, and making holes or recesses inoperative Indoor ventilation

Description of the invention

La bandeja que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta asegurando unas óptimas condiciones de ventilación, como ya se ha apuntado con anterioridad, a la vez que dicha bandeja adquiere una nueva configuración, sustancialmente ajena al clásico prisma rectangular, que es de la que por un lado se deriva la mejora en las condiciones de circulación del aire entre bandejas palatizadas, y por otro lado repercute de forma muy positiva en el aspecto estético de tales bandejas.The tray that the invention proposes resolves from the problem was fully satisfactory before exposed ensuring optimal ventilation conditions, such as It has already been signed before, at the same time that the tray acquires a new configuration, substantially foreign to the classic rectangular prism, which is from which on the one hand the improvement is derived in the conditions of air circulation between trays palatized, and on the other hand it has a very positive impact on the aesthetic appearance of such trays.

Para ello, de forma más concreta y a partir de la estructuración básica y convencional anteriormente citada, según la cual en la caja participa un fondo, dos gualderas con prolongaciones extremas y dos testeros dobles, la bandeja de la invención centra sus características en el hecho de que sus testeros adoptan un contorno hexagonal a la vez que sus gualderas adoptan una configuración diédrica sustancialmente obtusa, con lo que se consigue que, en la paletización de las bandejas cada una de ellas resulte contactante con las adyacentes, en los laterales correspondientes a sus gualderas, exclusivamente a través de una arista, definiéndose espacios prismático-triangulares entre ellas, que se abren tanto hacia la cara frontal como hacia la cara posterior del palet, y que aseguran unas óptimas condiciones de ventilación.To do this, more specifically and from the basic and conventional structuring mentioned above, according to the which one fund participates in the box, two wards with extreme extensions and two double heads, the tray of the invention focuses its characteristics on the fact that its testeros adopt a hexagonal contour at the same time as their gates they adopt a substantially obtuse dihedral configuration, with what which is achieved that, in the palletizing of the trays each of they are contacted with the adjacent ones, on the sides corresponding to their gates, exclusively through a edge, defining spaces prismatic-triangular between them, which open both towards the front face and towards the back side of the pallet, and that ensure optimal ventilation conditions.

El aire accede al interior de las bandejas no sólo a través de los clásicos orificios establecidos en el fondo de las mismas y de los rebajes que las gualderas presentan con respecto a los testeros, sino también a través de orificios establecidos en correspondencia con la arista de plegado intermedia de las gualderas, lo que a su vez establece comunicación no sólo entre el interior y el interior de la bandeja sino entre los espacios definidos entre bandejas por encima y por debajo de las aristas de unión a través de las que contactan.The air access inside the trays does not only through the classic holes set in the bottom of the same and of the recesses that the gualderas present with respect to the heads, but also through holes established in correspondence with the intermediate folding edge of the gualderas, which in turn establishes communication not only between the inside and the inside of the tray but between defined spaces between trays above and below joining edges through which they contact.

Para permitir el armado de la bandeja las clásicas prolongaciones de las gualderas afectan exclusivamente a estas últimas por encima de la arista de plegado del diedro que han de configurar, y adoptan una configuración apropiada para que no interfieran en su posición definitiva en el seno de los dobles testeros, los cuales pueden presentar la citada configuración o contorno hexagonal tan sólo en su tramo inicial, el que ha de configurar su pared externa, o bien en ambos tramos, pudiendo además rematarse en la clásica lengüeta de auto-armado de la caja al fondo de la misma, o ser dicha porción interior más corta, al carecer de dicha lengüeta y fijarse el armado de la caja mediante adhesivo.To allow the assembly of the tray the classic extensions of the gates exclusively affect the latter above the folding edge of the dihedral that have to configure, and adopt an appropriate configuration so that interfere in their final position within the doubles testeros, which can present the aforementioned configuration or hexagonal contour only in its initial section, which has to configure your external wall, or in both sections, being able to also finish off in the classic tongue of self-assembling the box at the bottom of it, or be said shorter inner portion, lacking said tongue and fix the box assembly using adhesive.

La figura 1 - Muestra un desarrollo en planta de una bandeja de cartón para productos perecederos realizada de acuerdo con el objeto de la presente invención.Figure 1 - Shows a development in plan of a cardboard tray for perishable products made of according to the object of the present invention.

La figura 2.- Muestra, ahora según una vista en perspectiva, la misma caja de la figura anterior debidamente armada.Figure 2.- Shows, now according to a view in perspective, the same box from the previous figure properly navy.

Preferred Embodiment of the Invention

A la vista de las figuras reseñadas puede observarse como la bandeja que se preconiza está constituida mediante un cuerpo laminar y monopieza (1), de cartón, en el que mediante líneas de plegado (2) se define un fondo rectangular (3), con orificios de aireación (4) quedando dicho fondo (3) rodeado por una pareja de gualderas (5) y una pareja de testeros (6), las primeras con rebajes (7) sobre su borde superior, que las hace más bajas que los testeros (6), y estos últimos dobles, con dos sectores (6-6') relacionados entre sí mediante una línea de plegado intermedia (8), contando las gualderas (5) con prolongaciones extremas (9) para armado de la bandeja, destinadas a alojarse en el seno de los dobles testeros (6-6').In view of the figures outlined you can observe how the tray that is recommended is constituted by means of a laminar and single-piece body (1), of cardboard, in which by means of folding lines (2) a rectangular bottom (3) is defined, with aeration holes (4) said bottom (3) being surrounded by a pair of garters (5) and a pair of testeros (6), the first with recesses (7) on its upper edge, which makes them more lower than the testeros (6), and the latter doubles, with two related sectors (6-6 ') by means of a intermediate folding line (8), counting the gualderas (5) with extreme extensions (9) for tray assembly, intended for to stay in the bosom of the double heads (6-6 ').

De acuerdo con la esencialidad de la invención al menos el sector proximal (6) de cada testero adopta una configuración hexagonal, que puede hacerse extensiva o no a su sector terminal (6'), mientras que las gualderas (5) incorporan, a nivel de los vértices laterales (10) de los testeros (6), sendas líneas longitudinales de plegado (11) que permiten que cada gualdera (15) se convierta en un diedro obtuso, de concavidad interior, como se observa especialmente en la figura 2, diedro cuya arista (11) queda preferentemente desfasada hacia abajo, de acuerdo con la asimetría prevista para los testeros (6).According to the essentiality of the invention at minus the proximal sector (6) of each testator adopts a hexagonal configuration, which can be extended or not to your terminal sector (6 '), while the railings (5) incorporate, to level of lateral vertices (10) of the testers (6), paths longitudinal fold lines (11) that allow each gualdera (15) becomes an obtuse, concavity dihedral interior, as seen especially in figure 2, dihedral whose edge (11) is preferably offset down, according with the asymmetry provided for the testeros (6).

Complementariamente las prolongaciones (9) de las gualderas (5) afectan exclusivamente a la zona de sus bordes laterales situada por encima de las citadas aristas (11) de los diedros configurados por dichas gualderas, al objeto de permitir el plegado o formación de dichos diedros sin interferir sobre el fondo de la caja, de manera que la línea (12) de unión articulada de cada prolongación (9) a la correspondiente gualdera (5), se remata en una línea de corte (13) acodada obtusamente hacia fuera, que es la que permite la necesaria e ineludible basculación descendente de la prolongación (9) cuando se produce la inflexión de la gualdera (5) correspondiente.Complementarily the extensions (9) of the gualderas (5) exclusively affect the area of its edges lateral located above the mentioned edges (11) of the dihedrals set up by these gangs, in order to allow folding or formation of said dihedrals without interfering with the background of the box, so that the articulated joint line (12) of each extension (9) to the corresponding rack (5), it is finished off in a cutting line (13) obtusely bent out, which is the which allows the necessary and inescapable downward tilt of the prolongation (9) when the inflection of the gualdera occurs (5) correspondent.

Sobre la propia línea de plegado (11) de las gualderas (5) se establecen orificios (14) de aireación, similares a los orificios (4) del fondo.On the folding line (11) of the holes (5) are established holes (14) of aeration, similar to the holes (4) at the bottom.

El sector terminal (6') de los testeros puede estar provisto de una pequeña lengüeta (15) acoplable en una ranura complementaria (16) del fondo (3) de la bandeja, cuando se prevea al auto-armado de la misma, o bien dicho sector terminal (6') puede carecer de la lengüeta (15), y ser de mayor o menor altura, cuando se prevé que el armado de la caja se lleve a cabo mediante adhesivo.The terminal sector (6 ') of the testeros can be provided with a small tongue (15) attachable in a groove complementary (16) to the bottom (3) of the tray, when provided to the self-armed of the same, or said sector terminal (6 ') may lack the tongue (15), and be larger or lower height, when it is expected that the assembly of the box is taken to out by adhesive.

En cualquier caso se consigue, tal como muestra la figura 2, una bandeja que adopta la configuración de un prisma hexagonal tumbado, que resulta perfectamente apilable por cuanto que su base inferior coincide dimensionalmente con su embocadura o base superior, cuyos testeros son planos pero con un contorno hexagonal, y cuyas gualderas adoptan una configuración diédrica que en el acoplamiento lateral entre cajas hace que se definan entre ellas amplios espacios de ventilación, que aseguran a su vez una perfecta aireación del producto contenido en su interior, con independencia de cuál sea la posición de la bandeja en el contexto del palet.In any case it is achieved, as shown Figure 2, a tray that adopts the configuration of a prism lying hexagonal, which is perfectly stackable because that its lower base coincides dimensionally with its mouthpiece or upper base, whose heads are flat but with an outline hexagonal, and whose gualderas adopt a dihedral configuration that in the lateral coupling between boxes makes them defined between they ample ventilation spaces, which in turn ensure a perfect aeration of the product contained inside, with regardless of the position of the tray in the context of the pallet.
