Disassemblable and stackable crate

Abstract

A disassemblable and stackable crate comprising four sides consisting of two longitudinal members (1, 1') opposite one another and two end members (2, 2') opposite one another, a bottom (3) and four blocks (4) located in each of the corners forming the crate. Each of the blocks (4) comprises a vertex (41), an inner face (42), and two outer faces (43), wherein said inner and outer faces (42, 43) correspond respectively with the projection of the hypotenuse and of the sides of a triangle forming the configuration of each block (4). The inner face (42) of each block (4) comprises two elongated mounting holes (4a) perpendicular to one another arranged as slots configured for coupling and fitting a corresponding tab (la, 2a) of each side (1, 1', 2, 2'), wherein each tab (la, 2a) has a length (1x, 2x) that is less than the length of the outer face (43) of the corresponding block (4).

Description

technical field [0001] The present invention relates to a crate of the type primarily constructed of wood or MDF (Medium Density Fibreboard) or a combination of both, and sometimes of metal, with the particularity that the metal components do not have access to the contents. Background technique [0002] Cardboard box solutions are particularly cost-effective for packaging any type of fruit and vegetable product, but have the disadvantage of being extremely sensitive to wet conditions, so to prevent them from degrading, cardboard is often covered with plastic, making the product more expensive. In addition, in order to achieve a secure assembly, it is necessary to use adhesives between the different parts making up the crate, necessitating the use of additional adhesive members. [0003] There are also crate solutions made from wood or wood by-products such as plywood, medium density fibreboard or other similar types, which are formed from parts fastened to each other by nai...

AI Technical Summary

Problems solved by technology

[0009] a) During its manufacture, in order for all parts to fit together correctly, there is no alternative but that the mechanical tolerances should be small, so the parts that make up the crate must be cut with a precision system (for example by laser cutting), so that Its manufacturing process is more expensive

[0010] b) In a vertical stack, when they are handled, especially when the crates are stacked for transport, the crates bounce up and down, may move suddenly, or they are simply not properly aligned, resulting in Cracked fastening element

[0011] This last issue means that the crates will be subjected to greater stress than calculated during design, meaning they may even crack

In addition, most crates have several protrusions, which amplifies the stacking problem, making vertical stacking more difficult and crates more prone to cracking (cracking should not only be understood as cracking itself, but also as the crate becoming unusable. right angle)
