Abstract

Glueless mountable box that is formed from a sheet of cardboard comprising a bottom panel (1) from which two lateral edges or side panels (2) and two end panels (3) emerge, along with four flaps (4). The flaps are joined by fold lines at both the end panels and the side panels, and with cut lines which, together with the fold lines, enable the flaps on the end panels and side panels to be folded, overlapping with the end panels, to shape the box. The ends panels have slots serving as hand holes, while the flaps have oblong slots (4.1) such that, when the flaps (4) are folded, said slots (4.1) are arranged in a position coincident with the flaps (3.1), thereby obtaining a box that is easily assembled, without the need for additional fastening means, providing greater structural and constructive stability.

El objeto de la presente invención, tal y como el título de la invención establece, es una caja montable sin necesidad de emplear medios de pegado alguno, siendo directamente montable como resultado del plegado de las solapas respecto de los testeros y gualderas, The object of the present invention, as the title of the invention establishes, is a mountable box without the need to use any means of gluing, being directly mountable as a result of folding the flaps with respect to the slats and slats,

10 quedando superpuestas sobre los testeros. 10 being superimposed on the heads.

Caracteriza la presente invención, el hecho de que a partir de una única lámina troquelada, sobre la que se han realizado una serie de marcas o hendidos, se puede configurar una caja The present invention characterizes, the fact that from a single die-cut sheet, on which a series of marks or creases have been made, a box can be configured

o bandeja resistente y portante de productos en su interior sin necesidad de tener que 15 emplear medios adicionales para el conformado de la caja. or resistant and bearing tray of products inside without having to use additional means for forming the box.

Por lo tanto, la presente invención se circunscribe dentro del ámbito de las cajas o bandejas de cartón montables por sus propios medios. Therefore, the present invention is circumscribed within the scope of movable cardboard boxes or trays by their own means.

20 BACKGROUND OF THE INVENTION

Las cajas abiertas superiormente o también denominadas bandejas en general, casi siempre comprenden un fondo de cuyos bordes emergen unas gualderas y unos testeros. Para el conformado de la caja se disponen unas solapas que bien emergen de los testeros o de las The open boxes superiorly or also denominated trays in general, almost always comprise a bottom from whose edges emerge some gualderas and some testeros. For the forming of the box there are some flaps that well emerge from the heads or from the

25 gualderas, que se pliegan y se adhieren sobre el testero o gualdera contiguo. 25 gualderas, which fold and adhere on the adjoining booth.

Este diseño de la lámina de cartón troquelado del que se parte para la conformación de las cajas, obliga a realizar un proceso de montaje de las cajas bien en fábrica o in situ, pero en cualquier caso con maquinaria especializada ya que requiere el pegado de las solapas This design of the die-cut cardboard sheet from which the boxes are formed, forces to carry out a process of assembling the boxes either in the factory or on site, but in any case with specialized machinery since it requires the bonding of the boxes. flaps

30 sobre los testeros y gualderas o laterales. 30 on the front and side or sidewalks.

Además, el grado de aprovechamiento de las láminas de cartón no es del 100% ya que se hace necesario el corte de las solapas hasta el punto de unión con los testeros o gualderas. In addition, the degree of use of the cardboard sheets is not 100% since it is necessary to cut the flaps to the point of attachment with the slats.

35 La resistencia lograda está limitada por la estructura de la propia lámina y por los puntos de pegado o adherencia de las solapas en las gualderas o testeros. 35 The resistance achieved is limited by the structure of the sheet itself and by the points of bonding or adhesion of the flaps in the slats or slats.

DESCRIPTION OF THE INVENTION

10 La presente invención está relacionada con una caja montable sin pegado caracterizada porque se puede montar a partir de una lámina troquelada y hendida con un sencillo gesto de plegado de las solapas respecto de las gualderas y testeros. The present invention relates to a mountable box without gluing characterized in that it can be mounted from a die-cut and creased sheet with a simple folding gesture of the flaps with respect to the slats and slats.

15 La lámina de cartón de la que se parte para el montaje de la lámina comprende un fondo de cuyos bordes emergen unos laterales o gualderas y dos testeros, además cuenta con cuatro solapas que están unidas con unas líneas de plegado tanto a los testeros como a las gualderas, y con una línea de corte que conjuntamente con las líneas de plegado permite plegar las solapas respecto de los testeros y gualderas dejándolas superpuestas con los 15 The cardboard sheet from which the sheet is assembled includes a bottom whose edges emerge from side or slats and two slats, it also has four flaps that are joined with folding lines to both the heads and to the gates, and with a cutting line that together with the folding lines allows the flaps to be folded with respect to the slats and slats leaving them superimposed with the

20 testeros en el conformado de la caja. 20 testeros in the forming of the box.

Los testeros cuentan con unos troquelados que definen unas solapas abatibles que dejan visible una abertura oblonga a modo de asa. Las solapas cuentan con unos cortes en forma de asa, de manera que en el plegado de las solapas, dichas aberturas en forma de asa The testeros have a few punches that define folding flaps that make visible an oblong opening as a handle. The flaps have handle-shaped cuts, so that in the folding of the flaps, said handle-shaped openings

25 quedan dispuestas de manera superpuesta sobre la solapa de los testeros, así de este modo, al quedar todos los cortes superpuestos, se puede hacer pasar la solapa de los testeros por las aberturas a modo de asa de las solapas produciendo el engatillado de las tres partes y asegurando la estabilidad y la conformación de la caja. 25 are arranged superimposed on the lapels of the heads, so in this way, when all the cuts are superimposed, the lapels of the heads can be passed through the openings as a handle of the flaps producing the crimp of the three parts and ensuring the stability and conformation of the box.

30 El posicionamiento de los cortes oblongos realizados en las solapas y, en particular, la distancia que hay hasta la línea de plegado con las gualderas, delimitará la configuración final de la caja pudiendo tener una mayor o menor conicidad. 30 The positioning of the oblong cuts made in the flaps and, in particular, the distance to the folding line with the gauges, will define the final configuration of the box and may have a greater or lesser taper.

La línea de corte de las solapas en su unión con los testeros es una línea de corte recta que 35 discurre por la unión de ambas partes, para a continuación adoptar una disposición inclinada The line of cut of the flaps in their union with the heads is a straight line of cut that runs through the union of both parts, to then adopt an inclined arrangement

REALIZACIÓN PREFERENTE DE LA INVENCIÓN PREFERRED EMBODIMENT OF THE INVENTION

30 A la vista de las figuras, seguidamente se describe un modo de realización preferente de la invención propuesta. In view of the figures, a preferred embodiment of the proposed invention is described below.

La caja objeto de la invención se conforma a partir de una lámina de cartón troquelado sobre 35 la que se han realizado una serie de líneas de hendido, en particular presenta: -Un fondo (1) The box object of the invention is formed from a sheet of cardboard stamped on which a series of creasing lines have been made, in particular it has: - A bottom (1)

-Dos gualderas o laterales (2) -Dos testeros (3) -Cuatros solapas (4) unidas tanto a las gualderas (2) como a los testeros (3) -Two gualdera or lateral (2) -Two pointers (3) -Four flaps (4) attached to both the gualdera (2) and the testeros (3)

presentando una línea de corte en su unión con los testeros y unas líneas de presenting a cutting line in its union with the heads and some lines of

5 plegado en su unión con los testeros y gualderas tales que permite el plegado y la disposición superpuesta de las solapas sobre los testeros en el conformado de la caja. 5 folded at its junction with the poles and slats such that it allows the folding and the superimposed arrangement of the flaps on the pockets in the shape of the box.

Los dos testeros (3) presentan un corte de forma oblonga que permite definir unas solapas 10 abatibles (3.1) por una línea de plegado (3.2) en su unión con los testeros, de manera que al plegarse dejan visible un corte a modo de asa. The two testers (3) have an oblong cut that allows to define folding flaps 10 (3.1) by a fold line (3.2) in their union with the testers, so that when folded they leave visible a handle-like cut .

Las cuatros solapas presentan unos cortes oblongos (4.1) dispuestos de manera que, una vez plegadas y superpuestas sobre los testeros, dichos cortes (4.1) quedan coincidentes 15 con la solapa (3.1) de los testeros. The four flaps have oblong cuts (4.1) arranged so that, once folded and superimposed on the heads, said cuts (4.1) coincide with the flap (3.1) of the heads.

El posicionamiento de los cortes oblongos (4.1) a modo de asa realizados sobre las solapas The positioning of the oblong cuts (4.1) as a handle made on the flaps

(4) es tal que la distancia (d1), distancia desde el corte oblongo (4.1) hasta el borde de la solapa, es igual a la distancia (d4) de la solapa (3.1) realizada en los testeros. También, la (4) is such that the distance (d1), distance from the oblong cut (4.1) to the edge of the flap, is equal to the distance (d4) of the flap (3.1) made in the heads. Also, the

20 distancia (d2) que va desde el corte oblongo (4.1) hasta al línea de plegado (4.3) con el testero, es igual a la distancia (d5), que es la distancia que va desde el borde inferior de la solapa (3.1) hasta la línea de plegado con el fondo. De esta manera la altura a la que quedan los cortes oblongos (4.1) con las solapas (3.1) de los testeros es la misma. 20 distance (d2) that goes from the oblong cut (4.1) to the fold line (4.3) with the tester, is equal to the distance (d5), which is the distance that goes from the bottom edge of the flap (3.1 ) to the fold line with the bottom. In this way the height at which the oblong cuts (4.1) with the flaps (3.1) of the heads are left is the same.

25 Por otro lado, la distancia (d3) que va desde el extremo del corte oblongo (4.1) hasta la línea de plegado entre la solapa (4) y la gualdera (2), no tiene por qué ser igual a la distancia (d6), que es la distancia que va desde el extremo de la solapa (3.1) hasta la línea de plegado 25 On the other hand, the distance (d3) that goes from the end of the oblong cut (4.1) to the fold line between the flap (4) and the rail (2), does not have to be equal to the distance (d6 ), which is the distance from the end of the flap (3.1) to the folding line

(4.3) entre el testero (3) y la solapa (4). Así, si la distancia (d3) es mayor que la distancia (4.3) between the tester (3) and the flap (4). Thus, if the distance (d3) is greater than the distance

(d6) se consigue conformar una caja con una ligera conicidad, es decir, superficie de acceso 30 mayor que la del fondo de la caja, al hacer coincidir los cortes oblongos (4.1) con la solapa (d6) it is possible to form a box with a slight conicity, that is, access surface 30 greater than that of the bottom of the box, by matching the oblong cuts (4.1) with the flap

(3.1) de los testeros. Esta característica facilita su maniobrabilidad y capacidad de almacenamiento. (3.1) of the testeros. This feature facilitates maneuverability and storage capacity.

Las solapas (4) cuentan en su unión con los testeros, con una línea de corte (4.2) que tiene 35 un primer tramo vertical coincidente con la línea de unión de ambas partes y que luego se dirige de manera inclinada hacia el interior de la solapa hasta el punto de convergencia con The flaps (4) have in their union with the heads, with a line of cut (4.2) that has a first vertical section coinciding with the line of union of both parts and that then is directed inclined towards the interior of the overlap to the point of convergence with

(4) cuentan con una línea de plegado (4.3) en su unión con los testeros. (4) they have a folding line (4.3) in their union with the heads.

Esta configuración de las líneas de corte (4.2) y de las líneas de plegado (4.3) y (4.4) 5 permiten el plegado y la superposición de las solapas (4) sobre los testeros (3), tal y como se observa en la figura 2. This configuration of the cutting lines (4.2) and the folding lines (4.3) and (4.4) 5 allow the folding and overlapping of the flaps (4) on the heads (3), as observed in the figure 2.

En la figura 3, se muestra la caja conformada, donde se aprecia la disposición superpuesta de los testeros (3) y de las dos solapas adyacentes (4), quedando coincidentes los cortes In figure 3, the shaped box is shown, where the overlapping arrangement of the pockets (3) and the two adjacent flaps (4) is shown, the cuts being coincident

10 oblongos (4.1) a modo de asa. En la figura 4, se observa cómo la solapa (3.1) de los testeros se ha hecho pasar por dichos cortes oblongo (4.1) a modo de asa, consiguiendo la retención y engatillado de la caja. 10 oblong (4.1) as a handle. In figure 4, it is observed how the flap (3.1) of the heads has been passed through said oblong cuts (4.1) as a handle, achieving the retention and snagging of the box.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement

The object of the present invention is a mountable cardboard box without glue formed by a bottom from which two sides and two sides emerge. It also has 4 flaps joined simultaneously by folding lines to both the gualdera and the front. These flaps have cut lines so that when folded they are superimposed with the heads.

There is an extensive number of mountable boxes formed from a single piece, so the basic selection criterion is the presence of flaps attached to both the gualdera and the front and also the existence of cut lines in the flap itself, condition that documents D1 and D2 meet, which determines that claim 1 lacks novelty.

The flap must have a first section of vertical cut and subsequently inclined, as in document D2, so claim 2 is not new.

Claims 3 and 4 relate to the arrangement adopted by the gaps available in the flaps and in the pockets to form a gripping area, integrated within the structure of the box itself.

It is considered that this conformation would be obvious to a person skilled in the art combining documents D2 and D3, so claims 3 and 4 do not imply inventive activity.
