ABSTRACT:
A cardboard container (1) is described particularly for solid, granular or powder products, but also adaptable to contain fluid products, in particular paste or cream products and the like. The container is obtained from two cardboard blanks (10), (11), the first giving rise to the body of the container, the second to a top closure wall. The body of the container rises conically from a rectangular base (2) to give rise at the top to a substantially octagonal mouth, wherein is inserted said reclosure cover (8) having peripheral flaps (h) upwardly folded and positioned inside the mouth of the container, to be blocked by corresponding flaps (f, f′) of the upper edge (3) of the container (1), which are folded inwardly and fixed by means of glue or heat-sealing adhesive. In one embodiment, the container (1) can be made hermetic, for containing fluid products, by applying a film (40) to the blank wherefrom the body of the container is produced, and a thin layer of aluminium (50) to the blank (11) giving rise to said top closure wall (8), wherein a cut line (22, 23) is provided to facilitate removal of a disk (8′) and form an opening for access to the product. A method for production of such a container is also described.
