Benefits of technology

The present invention aims to overcome the disadvantages associated with the formation of boxes, such as complexity and lack of strength. It also aims to make it easier to form the boxes, with minimum handling time and as ergonomically as possible. The invention achieves this by using a double-sided panel with cutting and score lines, which can be partially cut to form an oblong aperture serving as a handle and a flap that ensures structural stability of the tray when the panels match. The resultant packaging has a minimum processing during production, achieved from a single sheet, which may optionally have a central gluing area at the base. Additionally, the packaging has a double bottom, resulting in greater load capacity without the bottom collapsing.

Problems solved by technology

The need to apply a number of gluing points on the overlapping surfaces, after folding the panels, the side walls, the front walls and the flaps, complicates the formation of the boxes.
On one hand, if the boxes are factory-assembled, transporting empty boxes is bulky and expensive.
On the other hand, if the boxes are transported before assembling, there should be machines for assembling the boxes in situ, which is a disadvantage.
Generally these boxes have a complex geometry; they do not guarantee enough structural stability and strength.

Embodiment Construction

[0022]In FIG. 1, the initial die-cut, cut and scored sheet can be seen. This sheet is the starting point towards the arrangement shown in FIG. 3, from which a tray as the one shown in FIG. 2 can be self-assembled.

[0023]The sheet has an essentially rectangular configuration, divided into panels, adopting a three-by-three matrix configuration, having an upper row of three panels, aligned, followed by an intermediate row, of three panels as well, and finally a lower row of three panels, their connecting sides having the same dimensions.

[0024]On its intermediate row, the sheet has a central panel (1) and two end panels (2) at each side of the central panel (1), these three panels forming the bottom of the box.

[0025]The central panel (1) is connected to front panels (3) and (6) and to end panels (2) by a folding line (1.1).

[0026]In the upper row there is a central panel (3) and two panels at each side (4) and (5), each of them with a handle. In the lower row there is a central panel (6) ...

Abstract

A tray formed from a sheet divided into panels, adopting a three-by-three matrix configuration, provided with a central, an upper and a lower row, each with three panels, wherein the sheet has a central panel and two end panels at its intermediate row, one at each side of central panel, these three panels intended to form the bottom, while in the upper and lower rows, there is a central panel and respectively and two panels with handle at each side, wherein additionally the end panels from each row are refolded over central panels, wherein optionally the overlapping surface of panels is glued through one or several gluing points, such that a tray with a minimum production processing, made on a single machine, and erectable “in situ”, is obtained.

Description

FIELD OF THE INVENTION[0001]This application claims the benefit of European Patent Application EP 12382005.2, filed on Jan. 11, 2012, the contents of which application are herein incorporated by reference in their entirety.FIELD OF THE INVENTION[0002]The present invention relates to boxes and trays made of cardboard, starting from a die-cut and cut sheet, and more particularly, to self-assembling boxes.BACKGROUND OF THE INVENTION[0003]The state of the art shows many cardboard boxes formed from die-cut and cut cardboard sheets, all of them having the feature that once the sheet is cut, folding and a subsequent gluing are required to ensure structural strength and stability.[0004]The need to apply a number of gluing points on the overlapping surfaces, after folding the panels, the side walls, the front walls and the flaps, complicates the formation of the boxes. On one hand, if the boxes are factory-assembled, transporting empty boxes is bulky and expensive. On the other hand, if the ...
