1. A blank formed in a semi-rigid material such as cardboard and comprising:
- first, second, third and fourth rectangular panels in succession in that order and connected to each other by first, second and third vertical folding lines, a gluing lug connected to the first panel by a fourth vertical folding line, first, second, third and fourth flaps respectively connected to said first, second, third and fourth panels by first, second, third and fourth horizontal folding lines, fifth, sixth, seventh and eighth flaps respectively connected to said first, second, third and fourth panels opposite said first, second, third and fourth flaps by fifth, sixth, seventh and eighth horizontal folding lines, and first and second groups of deformation folding lines formed on said second and fourth panels and on said second and fourth flaps, substantially defining inverted Y-shapes whose branches respectively extend substantially from the middles of said second and fourth horizontal folding lines to said first and second vertical folding lines, on the one hand, and to said third and fourth vertical folding lines, on the other hand, and whose stems are in substantially median areas of said second and fourth flaps, wherein said first flap includes a tongue and said third flap and said third panel respectively include first and second slots both adapted to receive said tongue.

Abstract
Packaging suitable for food products has at least one wall which is formed in a semi-rigid material such as cardboard and has at least one edge defining an opening for inserting articles, in particular foods, and at least one first flap articulated to that edge along a folding line. The packaging can be conformed into a service configuration in which the flap uncovers the opening and a first storage configuration in which the flap closes the opening. The wall includes reversible deformation arrangements for conforming the packaging into a second storage configuration in which the first flap clamps the wall in a substantially sealed manner along the folding line and in the area of the edge.

3. A packaging, comprising:
-
first, second, third and fourth sides in succession in that order defining respectively first, second, third and fourth edges of an opening for inserting articles in said packaging, at least a first flap hinged to said first edge, and reversible deformation means provided on said second and fourth sides, so that said packaging can be conformed selectively;
in a service configuration in which said first flap uncovers said opening, in a first storage configuration in which said first flap closes said opening, and in a second storage configuration in which said first flap clamps said first, second, third and fourth sides along said first, second, third and fourth edges, wherein said packaging further comprises second and fourth flaps which remain hinged respectively to said second and fourth edges after the first opening of said packaging, so that;
said second and fourth flaps uncover said opening when said packaging is conformed in said service configuration, said second and fourth flaps close said opening when said packaging is conformed in said first storage configuration, and wherein said first flap clamps said second and fourth flaps in a substantially sealed manner along said first and third edges when said packaging is conformed in said second storage configuration. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)
