Description

Title of the invention: Cardboard box for horticultural products with openings to view the product inside. TECHNOLOGY SECTOR

[0001] The present invention relates to a box for horticultural products, of the type made from a sheet of cardboard cut with a die-cut with folding lines, to obtain a box with closures that can be opened and closed, comprising one or more openings in order to view the product contained inside.

[0002] The object of the invention is to offer a 100% cardboard box, therefore much more ecological and easily recyclable than boxes of this type whose openings have transparent plastic sheets in order to view the product contained inside. CONTEXT OF THE INVENTION

[0003] In the context of the practical application of the invention, boxes were obtained by developing a die-cut cardboard sheet with fold lines, to obtain boxes with closures that can be opened and closed, comprising one or more openings to view the product contained inside.

[0004] In order to prevent the accidental release of the products contained inside the box, it includes a transparent plastic sheet over the opening(s), glued to the inner frame of the box.

[0005] The difference in composition between the main body of the box and the sheets covering the openings obviously makes this type of product difficult to recycle properly. Indeed, the two materials must be separated. The use of plastics also poses an environmental problem, even if they are recyclable. DESCRIPTION OF THE INVENTION

[0006] The box proposed by the invention solves the aforementioned problem in a completely satisfactory manner, based on a simple but very effective solution.

[0007] To this end, and more specifically, starting from the structure of any box of this type in which a single die-cut sheet of cardboard is used, which, once assembled, forms a package that can be opened and closed, that is to say, the lid(s) of the package form a single piece with the rest of it, the package having one or more grooves for openings to view the product contained inside. The invention focuses its features on the fact that, instead of the traditional transparent plastic sheet that covers the openings, it provides a paper mesh that adheres internally to the perimeter frame of the opening(s).

[0008] As for the paper mesh, it will be obtained from long pine fibers (100%). Once the kraft pulp is produced, a polyamidoamine-epichlorohydrin resin is added, giving it ideal properties for rope manufacturing and ensuring that the final product retains its mechanical properties under high humidity conditions.

[0009] This results in packaging with identical performance, but made entirely of cardboard / paper, which is much more environmentally friendly. Brief description of the drawings

[0010] To supplement the description that will follow, and to allow for a better understanding of the features of the invention, in accordance with an example chosen for its practical implementation, a series of drawings is attached, within the framework of said description, and the following elements are represented therein, by way of example and not exhaustively:

[0011] Fig. 1 represents a perspective view of a cardboard box for horticultural products with openings to view the product contained inside, designed in accordance with the object of the present invention.

[0012] Fig. 2 represents a perspective view of a second embodiment of the box of the invention.

[0013] Figure 3 finally shows a perspective view of a third version of the multiple embodiments that the box of the invention can present. SELECTED EMBODIMENT OF THE INVENTION

[0014] As shown in the figures provided, the box of the invention is made, as is traditional, from a sheet of cardboard (1) with cutting and folding lines, and once assembled, it forms a package whose lid(s) (2-2') are a single piece with the package itself. The latter can take on a wide variety of shapes according to different design lines, such as those illustrated in Figures 1 to 3, as well as many others, without affecting the essence of the invention. Indeed, said design has no impact on the structural features that are the focus of the content of the claim of the present invention.

[0015] In accordance with the essence of the invention, the packaging is provided with one or more openings (3) in order to view the product contained inside, which can be distributed on the sides, on the lid, or even on both, as shown in the embodiments of figures 1 and 3, openings which are supported on their inner face by a paper mesh (4), fixed by adhesive to the perimeter frame of said openings.

[0016] These packages can be assembled manually or automatically, without affecting the essence of the invention. They can also have chamfered corners (8), as in the version of [Fig.2], or sharp corners, without affecting the essence of the invention, and can include, as mentioned above, one or two lids (2-2') with coupling means (6) for a stable closure.

[0017] The mesh (4) will be obtained from long pine fibers (100%). Once the kraft pulp is produced, a polyamidoamine-epichlorohydrin resin is added, giving it ideal properties for rope manufacturing and ensuring that the final product retains its mechanical properties under high humidity conditions.

[0018] In addition, the paper's ability to absorb water must be controlled and, for this purpose, we add rosin resin, derived from conifer resin, which reduces the hygroscopicity of the paper.

[0019] In terms of grammage, paper of 30 g / m2 to 35 g / m2 can be used to obtain a rope diameter of approximately 0.5 mm.

[0020] The paper used for the sheet of the main body of the box preferably has a density between 40 and 100 g / m2.

[0021] The packaging thus described may include other openings or ventilation holes (7-7') of smaller dimensions, which need not necessarily be fitted with said mesh (4). Indeed, their smaller dimensions do not allow the products contained in the box to escape.

[0022] This results in packaging that is 100% recyclable in the blue bin, without the need to dispose of any part of it or produce any waste during the recycling process.
