The invention relates to a container (1), made from thermoplastic material (3), of the type with a domed base, comprising a central projecting pimple (4), a peripheral support region (5) and an intermediate arch (6), provided with ribs (7), extending from the central pimple to the support region but not therein, the ribs (7) having a dihedral form with a straight section in a V in the medial plane (7c), essentially parallel to the axis (1a) of the container and running into each other without a break. The ribs (7) have a longitudinal profile which is curvilinear, the bases (7d) of the ribs, in the region thereof adjacent to the central pimple (4), extending higher than the base of said central pimple and the bases (7d) and crests (7e) of the ribs, in the region thereof adjacent to the support region, having curves merging progressively into a continuous rounding of unbroken curvature immediately above the support region (5) such that the latter is essentially planar and continuous over the whole length thereof.
Récipient (1) en matériau thermoplastique pourvu d'un fond (3) du type "fond champagne" comportant un bouton central (4) saillant, une zone périphérique d'appui (5) et une voûte (6) intermédiaire pourvue de nervures (7) rayonnant du bouton central jusqu'à la zone d'appui, mais à l'exclusion de celle-ci ; les nervures (7) sont en forme de dièdre avec une section droite en V à plan médian (7c) sensiblement parallèle à l'axe (1a) du récipient et se succèdent les unes aux autres sans discontinuité ; les nervures (7) ont un profil longitudinal qui est curvi~ligne, les fonds (7d) des nervures, dans leur zone qui avoisine le bouton central (4), remontant plus haut que la base dudit bouton central et les fonds (7d) et arêtes (7e) des nervures, dans leurs zones qui avoisinent la zone d'appui, présentant des courbures se confondant progres~sivement en un arrondi continu et sans rupture de courbure immédiatement au-dessus de la zone d'appui (5) de manière telle que celle-ci soit sensiblement plane et continue sur toute son étendue.
