Abstract

Cardboard tray, of the type made up of a compact body, in which a rectangular and central sector corresponding to the bottom of the tray is established, delimited by four folding lines that relate it to the side walls of the tray, specifically with the two gualderas and the two end faces of the same, characterized in that said gualderas and end faces have the same height, counting one of these elements, such as the gualderas, with extensions at their ends delimited by folding lines, each being one of said extensions provided with a die-cut determining a coupling tongue for a complementary slot operatively established on the ends of the end caps, so that when assembling the tray, said extensions of the gualderas adapt to the internal face of the ends, and the tabs of the former fit into the grooves of the latter.

Description

Cardboard tray

Object of the invention

The present invention relates to a tray of cardboard, of the type constituted by a single piece body which, duly stamped, allows the self-assembly of the tray.

The object of the invention is to achieve a tray that, while maintaining its primitive flat configuration in the storage and transport phase, is self-assembling in an extraordinarily fast and simple maneuver, and with a minimum participation of
material.

Background of the invention

They are known cardboard trays based on a laminar body, conveniently stamped to obtain in it a large rectangular and central sector, corresponding to the fund of the tray, delimited by four folding lines after which set the major and minor side walls of the tray, generally counting the major side walls with extreme extensions intended to interlock in the walls minor laterals, for which the latter are double, they fold about themselves, they house the aforementioned extensions inside and they are definitely fixed to the bottom of the box by small existing tabs on its free edge, which are coupled tongue and groove in grooves established at the bottom of the tray.

This solution, perfectly valid from the theoretical and functional point of view, presented in practice as fundamental problem the consumption of material derived from double existing wall in the smaller walls of the tray, which means also a certain complexity in the assembly of it.

Description of the invention

The tray that the invention proposes resolves from fully satisfactory way the problem above exposed, ensuring a minimum material consumption for the conception of it, the derivative of the breadth of its background and of its depth

To do this and more specifically, the tray that it is recommended, also starting with a laminar and single-piece body with a central sector constituting the fund of the same, delimited by four fold lines beyond those established major or gualdera side walls and side walls minors or testeros of the tray, and also starting from the existence of such extensions of extreme extensions intended to adapt and fix to the front, focuses its characteristics on fact that two extensions are established stamped determinants of tabs intended to engage in slots of the heads during the assembly of the box.

The mentioned tabs, which can be adapted by example a semicircular configuration, will be oriented towards the beginning of the extensions in which they are located, so that the tendency of the tray to "open", in turn suppose a tendency for tongue interlocking in complementary grooves, so that the stability of the tray is insured

According to another of the characteristics of the invention the said extensions adopt a configuration straight trapecial, so that its lower edge is oblique and its width decreases towards its free tip, in order to facilitate in the dejection of the gates that these substantially exceed the perpendicularity with respect to the bottom of the tray, to allow and facilitate the interlocking of the tabs in the slots

Finally and according to another of the characteristics of the invention, the length of said grooves is also oversized with respect to the width of the tabs, to facilitate the coupling within them of these last.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as an integral part of said description, a set of drawings where with character Illustrative and not limiting, the following has been represented:

Figure 1.- Shows a development in plant of a cardboard tray made according to the object of the present invention

Figure 2.- Shows, according to a view in perspective, the tray of the previous figure properly navy.

Preferred Embodiment of the Invention

In view of the figures outlined you can Observe how the tray proposed by the invention is constituted from a laminar, single piece, compact cardboard body, with a remarkable solidity, in which a die is defined by large central and rectangular sector (1), corresponding to the fund of the tray, delimited by four folding lines (2), beyond which establish a pair of gualderas (3-3 ') and a pair of testeros (4-4 '), constituting the perimeter of the tray and preferably with matching heights.

Each rack (3) incorporates at its ends, and beyond the fold lines (5), respective extensions (6) likely to be orthogonally layered with respect to gualderas (3-3 ') and to adapt internally to the testeros (4-4 ').

Each extension (6) has a die cut (7) determinant of a tongue (8), which in the example of chosen practical implementation adopts a configuration noticeably semicircular, but that could adopt a trapecial configuration isoscelic or any other deemed convenient, being said tab (8) intended to be inserted into a slot (9) operatively practiced in each testero (4-4 ') near their ends, and in vertical arrangement, being positioned the slots (9) properly so that after receiving inside the respective tabs (8), the side walls (3) and (4) of the tray, that is to say their storage boxes and testeros adopt a provision substantially perpendicular to the bottom (1) of the tray.

In order to facilitate the mounting of the tabs (8) in the respective grooves (9), it is provided that the lower edge (10) of the extensions (6) is oblique, that is to say that said extensions adopt the straight trapecial configuration observed in figure 1, which allows a tilting of the slats (3) greater than 90 °, so that the tabs (8) move sufficiently inwards so that their front end is facing the grooves (9), and on the other hand it is provided that these grooves (9) are oversized both in width and in length with respect to the tabs (8), with the
same purpose of facilitating or favoring their insertion.

According to this structuring and from laminar and flat body shown in figure 1, for the assembly of the tray is enough to fold their gates (3) and their heads (4) on the folding lines (2), and in turn folding the extensions (6) on the folding lines (5), adapting said extensions (6) to the inside of the heads (4) and locking the tongues (8) in the slots (9), so that the tray is perfectly assembled with the prismatic-rectangular configuration shown in figure 2.

Although this description has been made in on the basis that the extensions (6) are of the gates (3), obviously such extensions could also be placed on the heads (4), in which case the slots (9) would be located in the gualderas (3).

Claims (3)

1. Cardboard tray, of the type constituted by a compact body, in which a rectangular and central sector corresponding to the bottom of the tray is established, delimited by four folding lines that relate it to the side walls of the tray , specifically with the two carcasses and the two heads of the same, characterized in that said carcasses and headboards have the same height, counting one of these elements, such as the carcasses, with extensions at their ends delimited by folding lines, each being one of said extensions provided with a determining die of a coupling tongue of a complementary groove operatively established on the ends of the heads, so that in the assembly of the tray the aforementioned extensions of the slats are adapted to the internal face of the testeros, and the tabs of the first fit into the slots of the second. 2. Cardboard tray according to claim 1, characterized in that the aforementioned extensions of the slats adopt a straight trapezoidal configuration, so that its lower edge is remarkably oblique, allowing the folding of the slats to substantially exceed 90 °, for that the tabs can access the complementary interlocking grooves. 3. Cardboard tray, according to previous claims, characterized in that said tabs are oriented towards the start or tilting line of the extensions in which they are located, and the complementary grooves are oversized both in length and in width with respect to such tabs. .
