BOX FOR TRANSPORTING VARIOUS PRODUCTS

Abstract

A box for transporting various products comprises a prismatic body and a closing cover formed by a multilayered material (10) including an intermediate thermal insulation board (11) with an inner face and an outer face provided with an inner coating (12) and an outer coating (13). The inner coating (12) comprises a paper sheet (121) attached to the inner face of the intermediate board (11) and a stiffening and waterproof sheet (122) that forms the inner surface of the body and the cover. The outer coating (13) comprises a first layer (131) made of strong printed paper or strong paper suitable for printing; a second paper layer (132); and a flexible and waterproof sheet (133) made of recyclable polymer and arranged between the first and the second paper layers.

Claims

1. A box for transporting various products comprising a prismatic body and a closing cover formed by a multilayered material (10) including an intermediate thermal insulation board (11) with an inner face and an outer face, respectively provided with an inner coating (12) and an outer coating; characterised in that: the inner coating (11) comprises: a paper sheet (121) attached to the inner face of the intermediate thermal insulation board (11); and a single-layered or multilayered stiffening and waterproof sheet (122) made of vinyl or recyclable polymer that forms the inner surface of the box; the outer coating (13) comprises: a first layer made of strong printed paper (131) or strong paper suitable for printing, which forms an outer surface of the box; a second strong paper layer (132) attached to the intermediate thermal insulation board (11); and a single-layered or multilayered flexible and waterproof sheet made of recyclable polymer (133) arranged between the first (131) and the second layers (132) of strong paper; and the inner coating (12) and the outer coating (13) cover the entire surface of the inner and outer faces of the intermediate thermal insulation board (11).

2. The box according to claim 1, characterised in that the intermediate thermal insulation board (11) is made of cardboard and has hollow cavities (11) arranged between two parallel walls (111, 112) and oriented parallel to said walls, as a corrugated cardboard, or transversely, as a honeycomb.

Description

DESCRIPTION OF THE FIGURES

[0021] As a complement to the description provided herein, and for the purpose of helping to make the features of the invention more readily understandable, the present specification is accompanied by a set of drawings which, for illustrative and non-limiting purposes, the following has been represented:

[0022] FIG. 1 shows a schematic view of an exemplary embodiment of the box for transporting various products according to the invention, with the cover separated from the body and provided on the outside with prints covered by a protective varnish layer.

[0023] FIG. 2 shows a stepped cross section of a portion of the material forming the body and the cover of the box of the previous figure, without the protective varnish layer, the structure of the intermediate board and of the inner and outer coatings thereof being visible in this cross section.

PREFERRED EMBODIMENT OF THE INVENTION

[0024] In the exemplary embodiment shown in FIG. 1, a box for transporting various products according to the invention can be seen, provided with a prismatic body and a cover made entirely of a multilayered material (10), the cross section of which can be seen in FIG. 2.

[0025] This multilayered material comprises: an intermediate thermal insulation board (11); an inner coating (12) oriented towards the inside of the box and attached to the inner face of the intermediate board (11); and an outer coating (13) forming the outer surface of the box, attached to the outer face of said intermediate board (11).

[0026] In the example shown, the intermediate thermal insulation board (11) is formed by corrugated cardboard which has hollow cavities (110) oriented longitudinally and arranged between two parallel walls (111,112).

[0027] The inner coating (12) comprises a paper sheet (121) attached to the inner face of the intermediate board (11) and a stiffening and waterproof sheet (122) that forms the inner surface of the box and which, in this specific case, comprises one or more layers made of recyclable polymer, for example, polyethylene or polypropylene.

[0028] The outer coating (13) comprises: a first strong paper layer (131) which forms a printable outer surface; a second strong paper layer (132) attached to the intermediate thermal insulation board (11); and a flexible and waterproof sheet made of recyclable polymer (133) arranged between the two layers of paper (131 and 132).

[0029] As seen in FIG. 1, the first strong paper layer (131), forming the outer surface of the box, is suitable for printing various motifs (14); the outer coating (13) having in this specific example a protective varnish layer (134) which protects both the first layer of paper (131) and the motifs (14) printed thereon.

[0030] Having sufficiently described the nature of the invention, as well as an example of a preferred embodiment, it is hereby stated for the relevant purposes that the materials, shape, size and layout of the described elements may be modified, provided that it does not imply altering the essential features of the invention claimed below.
