Cardboard container for solid, granular or possibly pasty products, and manufacturing method thereof
First Claim
1. A cardboard container having a substantially box-type shaped body, open at a top, and a top closure wall (8), characterised in that said body and said top closure wall are formed from two respective blanks (10, 11), said top closure wall (8) being disposed inside the container body, at a certain distance from an upper edge (3) thereof, and being provided with a pre-cut line (22, 23) able to facilitate detachment of a disk (8′
- ), to form an opening for access to the container,characterised in that it further comprises a reclosure cover (9), openable hingedly around one of a plurality of folded flaps (f, f′
) of the upper edge (3) of the container are being disposed, in a closed position, on said top closure wall (8) and on said peripheral edge (30), once said disk (8′
) for reclosing of the container has been removed, andcharacterised in that reclosure of said cover (9) takes place by snap closure, the front edge of said cover being disposed, with slight forcing, beneath at least one flap (f, f′
) of said upper edge (3) of the container, said at least one flap being shorter and thicker than the other flaps (f, f′
).

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.

12. A blank (10) for production of a container body for containing products, comprising:
-
a central rectangle (a) defining said container base (2), two opposed tongues (b) inwardly foldable about respective fold lines (12) coinciding with two opposite sides of the of the rectangle (a), two portions each shaped as an isosceles trapezium (c, c′
) foldable about two other sides (13, 13′
) of the rectangle (a), to form rear and front walls, respectively, of the container (1)two pairs of triangular portions (d, d, d′
, d′
) respectively adjacent said isosceles trapezium portions (c, c′
) and joined thereto by means of respective crease lines (14, 14′
), said triangular portions (d, d′
) having vertices coinciding with corresponding vertices of said rectangle (a), being able to form said blunted corners (7) of the container (1),first and second pairs of connecting portions, each portion in each of said first pair and said second pair being shaped as a trapezium (e, e, e′
, e′
), respectively adjacent said triangular portions (d, d, d′
, d′
), and joined thereto by respective crease lines (15, 15′
), the trapesium-shape portions in said second pair (e′
, e′
) being wider than the trapezium-shape portions in said first pair (e, e′
) and being provided on the respective outer edges with a strip of glue or heat-sealable adhesive (16, 16′
), for fixing to the corresponding trapezium-shaped portions in said first pair (e and e), to define, by superimposition of said first and second trapezium-shaped portions (e, e′
), the right and left side-walls of the container body and the closure thereof,a plurality of flaps (f, f′
), sealable on the inside, substantially shaped as isosceles trapezium, protruding respectively from said isosceles trapezium and triangular portions (c, d) and from said isosceles trapezium, triangular and second pair of trapezium-shaped portions (c′
, d′
, e′
),octagonal portion (g) connected by means of a fold line (18), to one of said flaps (f, f′
), to form said re-closure cover. - View Dependent Claims (10, 11, 13, 14)
