[0002] Technical problem

[0003] The technical problem that the present invention solves relates to the difficulty of assembling cardboard furniture for the display of products for sale, in sales locations.

[0004] This problem is also associated with the area of ​​environmental care, where the use of cardboard is beneficial, as it is a biodegradable material in the short term, which is convenient compared to recyclable and non-recyclable materials such as wood, plastic and metal, since recycling costs are comparatively very high when the production cost of furniture is sought to be very low, often economically preventing used and disposed of furniture from being adequately treated for environmental sustainability.

[0005] There are many technological solutions that have been disseminated that partially solve the problem, but most of them have not been able to adequately create a sufficiently strong and rigid structure without the use of metal or plastic elements to fasten or secure parts of the furniture, which poses an environmental problem in its final disposal.

[0006] On other occasions, the few technological solutions that have achieved structural objectives lack these plastic or metal parts. They require a complex assembly process at the site of use, which requires the intervention of qualified personnel. Furthermore, these technologies do not allow for simple and rapid deployment of the furniture.

[0007] Faced with the needs related to the different facets of this technical problem, it is necessary to achieve a cardboard furniture technology for the display of products for sale, in points of sale, in which the same can be obtained at least in its most substantial part by unfolding, without the need for parts of other materials such as wood, plastic or metal, while at the same time achieving high structural strength and rigidity.

[0031] The first two opposite vertical walls (17) of the tray may have a cross-section coinciding with a fold line on the central horizontal rectangular surface, which allows the article-containing tray to be folded like a hinge, allowing it to be packed in a length shorter than its total length, as well as to be introduced through small spaces and then unfolded.

[0032] A first inner sheet (25), made of semi-rigid and foldable material, with a width similar to the inner distance between the two first opposite vertical walls (17) and a length similar to the sum of the distance between the two second opposite vertical walls (20) and twice the width of the first portion of the tray profile (21), with a total cut in the shape of an “S” in the direction of its width, can be positioned on the central horizontal rectangular surface (15), with a virtual straight line centered on the cut coinciding with the fold line on the central horizontal rectangular surface (15), giving the article-containing tray greater rigidity and resistance to the weight of the articles to be supported.
