Claim:
1. A container, obtained by blow molding or stretch blow molding of a blank made of plastic material, which comprises a body, a shoulder in the extension of the body at an upper end thereof, and a neck in the extension of the shoulder, the shoulder being articulated between two stable positions, namely a deployed position in which the shoulder projects from the body, and a retracted position in which the shoulder is at least partially retracted into the body, wherein the shoulder is articulated in order to be able to adopt, in addition to the deployed position and the retracted position, a third stable position, intermediate between the deployed position and the retracted position, the shoulder comprising a peripheral section and a central section, a first articulation being defined at a junction between the peripheral section and the body, a second articulation being defined at a junction between the peripheral section and the central section, the peripheral section and the body defining at their junction an axially projecting ridge, a third articulation being defined by the junction between the central section and a section beneath the neck, the bottom of the container comprising at its center a vault defining a hollow reserve and at its periphery an inset that is complementary to the ridge; and wherein the container is configured such that transition of the shoulder from the third stable position to the retracted position is achieved by rotating the central section around the second articulation, while orientation of the peripheral section remains substantially unchanged and the neck is moved axially downwards along a central axis of the container.
