Abstract:
1. A container made of thermoplastic which can be filled with a hot liquid, this container comprising a body having a plurality of recessed panels extending substantially parallel to the axis of the body and distributed in a substantially equidistant manner around the body, these panels being separated by portions of the body that form beams extending substantially parallel to the axis of the body, wherein the panels are arranged on a number of levels around the body; the panels of two consecutive levels are separated by an annular portion of the body that forms a collar substantially in surface continuity with said beams; each beam is recessed to form a longitudinal central channel section, and the channel sections of the beams of the successive levels are connected to one another, in an angularly offset manner from a beam of one level to the consecutive beam of the adjacent level, by strongly inclined channel sections extending in said collars and all inclined in the same direction substantially parallel to one another, in such a way that the body is provided, right from top to bottom, with channel sections which, connected together, form channels configured as substantially parallel successive steps and distributed over the periphery of the body, whereby the annular parts of the body that are constituted by said collars are mechanically reinforced against a crushing force due to the vacuum generated by the restriction in volume of the liquid as it cools.
