Abstract: Mold base including a base wall and a peripheral side wall which is connected to the base wall by a fillet, this mould base ending with a peripheral upper edge and including ribs forming cavities for grooves for strengthening the base of a container to be formed and which each straddle the fillet, this mould base also including decompression vents hollowed out of the moulding face and which include, for each rib, at least one pair of shallow side channels which extend on either side of the rib and open, at an upper end, on to the peripheral upper edge.

Abstract: Container (1), obtained by blow molding or stretch blow molding of a blank made of plastic material, which comprises a body (2), a shoulder (3) in the extension of the body (2) at an upper end thereof, and a neck (4) in the extension of the shoulder (3), the shoulder (3) being articulated between two stable positions, namely a deployed position in which the shoulder (3) projects from the body (2), and a retracted position in which the shoulder (3) is at least partially retracted into the body (2), the shoulder (3) being 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.

Abstract: The invention relates to a container such as a bottle, flask, tank or similar for housing a product to be protected from light, said container being made from a thermoplastic material and produced by blowing or by draw-blowing of a preform, characterised in that said container has a layer of thermoplastic material loaded in a homogeneous manner with mica flakes at a level of 2 to 4% by weight with the addition of titanium oxide powder at a level of 2 to 4% by weight.
