Abstract
Disclosed is a mold for the manufacture, from a blank, of a container having a body and a base provided with a peripheral seat. The mold includes: a wall bearing the impression of the body of the container and provided with an opening; a mold base which is movable relative to the wall between an extended position and a retracted position; the mold base having a peripheral surface which corresponds to a join between the seat and the base of the container and terminates in an edge which is raised with respect to the seat surface. In the extended position of the mold base, the edge extends vertically perpendicular to the opening and, in the retracted position of the mold base, the edge extends near the opening.
