Pressurised container with deformable shoulder and deformable bottom

A container obtained by blow molding or stretch blow molding from a blank of plastics material, the container comprising:

• a body comprising an upper end and a lower end;
• a shoulder extending from the upper end of said body;
• a neck extending the shoulder,
• wherein the shoulder is articulated between at least two stable positions, wherein a first stable position is a deployed shoulder position in which the shoulder projects from the body, and wherein the second stable position is a retracted shoulder position in which the shoulder extends level with the upper end of the body or is at least partially withdrawn into the body;
• and
• a bottom at the lower end of said body,
• wherein the bottom is articulated with the lower end of the body between at least two additional stable positions, wherein the first additional stable position is a deployed bottom position in which the bottom extends level with the lower end of the body or projects at least partially from the body, and wherein the second additional position is a retracted bottom position in which said bottom is at least partially withdrawn into the body such that, when the container is filled and closed, moving the shoulder from the deployed position to the retracted position moves the bottom from the retracted position to the deployed position and vice versa.
