- the container In the first aspect, that is to say in what refers to resistance, the container must withstand the weight of the contents without undergoing deformation of bulging in its bottom, it must withstand the static stacking so that it must have high compression capacity, depending on the weight to be contained and the required stacking capacity, must withstand dynamic stacking, that is the vibrations and movements to which it is subjected during handling and transport, and must also withstand the environmental conditions of handling, storage and transport, especially in the face of the effects of environmental humidity, which in the case of the cold rooms in which these types of trays are normally located reaches 90%.
- the tray In the second aspect, that is to say, of its manageability, the tray must offer the possibility of being assembled, as required by small users, or disassembled, as in the case of large users, who will have their own facilities where the use of simple, light machines and the greatest possible automation is desirable.
- the tray must offer optimum possibility of high quality printing, and finally, from the point of view of its recyclable nature, it must lack elements that damage this aspect, such as staples or other non-recyclable materials.
- the trays of the first type that is to say the wooden trays, although they satisfactorily meet the first objective of the aforementioned, the resistance one, do not meet any of the remaining ones, since it is neither manageable, nor does it offer the possibility of printing certain quality, and it is not recyclable at low cost.
- the trays obtained are not sufficiently resistant to the compression efforts to which they will be subjected, when they are loaded with the merchandise and have to be stacked.
- the application of additional reinforcement pieces, especially located in the corners, is used.
- the faces of the tray are also reinforced by means of tabs or wings folded on the faces themselves.
- Compact cardboard offers important advantages over corrugated cardboard. On the one hand it is more resistant
- the compact cardboard has a better resistance to moisture than the corrugated cardboard.
- patent EP 1184289 a five-piece compact cardboard tray is described, in which the testers are first obtained, folding the end sectors that form the corner reinforcements and then such testers, together with the sides, are glued to the bottom of the tray.
- the object of the present invention is, therefore, a method of obtaining a compact cardboard tray, which starts from an optimized design of the three pieces that make up the tray, which in combination with an order and sequence of assembly of the pieces allows Total automation of the production process.
- the invention consists of a method of obtaining a compact cardboard tray comprising a bottom, two front and two sides, a process that is developed according to the following phases:
- a) obtain by die cut sheets of compact cardboard intended to constitute tray bottoms. These die-cut sheets comprise longitudinal and transverse fold lines that are configured to form longitudinal and transverse flaps in said tray bottom.
- b) obtain by die-cut sheets of compact cardboard formed to constitute pockets, which comprise transverse folding lines that are configured to constitute a central body and a plurality of transverse sectors at each end of said central body.
