An erectable packaging, comprising:

• a blank that forms at least one base and four lateral walls each extending between two lateral edges from a lower extremity secured to the base to a free upper extremity, said lateral walls comprising parallel, mutually opposite first and second lateral walls and parallel, mutually opposite third and fourth lateral walls, the third and fourth lateral walls being connected to the first and second lateral walls to enable each of said third and fourth walls to be moved between a storage position in which the upper extremities of said third and fourth lateral walls are relatively close to each other and an erected position in which the upper extremities of said third and fourth lateral walls are further away from each other,
• wherein the blank is cruciform and comprises first, second, third and fourth arms that respectively include the first, second, third and fourth lateral walls, each of said arms also including at least two flaps articulated on the corresponding lateral wall,
• wherein the flaps on the first, second, third and fourth lateral walls are all parallel to the first and second lateral walls, the flaps on the first and second lateral walls each comprise a lug and the flaps on each of the third and fourth walls each comprise a slit receiving one of said lugs to limit the displacement of the third and fourth lateral walls in the erected position,
• wherein the base and the lateral walls are connected to each other by at least a first flexible membrane enabling the packaging to contain a liquid in a leak proof manner,
• and wherein the flaps on the first and second lateral walls each comprise a first section articulated on one of the lateral edges of the corresponding lateral wall and a second section folded downwards and articulated on the upper edge of the first section, said second section being extended by one of said lugs that enters one of the slits in the flaps on the third and fourth lateral walls.
