Abstract

Container ( 1 ) made of plastics material, including a body ( 5 ) which extends along a main axis (X), and a base ( 6 ) which extends at a lower end of the body ( 5 ), the base ( 6 ) being provided with protruding feet ( 7 ) that are provided with crowns ( 11 ) which extend in a common setting-down plane ( 12 ), pairs of the feet ( 7 ) being separated by recessed grooves ( 15 ) which extend radially from a central region ( 8 ) of the base ( 6 ), each foot ( 7 ) having two flanks ( 17 ) that each laterally border a groove ( 15 ), characterized in that the flanks ( 17 ) of two adjacent feet ( 7 ) which border one and the same groove ( 15 ) form between one another, at the level of the setting-down plane ( 12 ) and in a plane transverse to the radial direction of extension of the groove ( 15 ), an obtuse angle (A) at the crown.

First claim

1 . Container ( 1 ) made of plastic material comprising a body ( 5 ), which extends along a main axis (X), and a bottom ( 6 ) that extends at a lower end of the body ( 5 ), the bottom ( 6 ) being provided with projecting feet ( 7 ) having apexes ( 11 ) that extend into a common standing plane ( 12 ), the feet ( 7 ) being separated into pairs by recessed grooves ( 15 ) that extend radially from a central area ( 8 ) of the bottom ( 6 ), each foot ( 7 ) exhibiting two sides ( 17 ) that each laterally border a groove ( 15 ), wherein the sides ( 17 ) of two adjacent feet ( 7 ) that border the same groove ( 15 ) form between them, in the area of the standing plane ( 12 ) and in a plane crosswise to the radial direction of extension of the groove ( 15 ), an angle (A) that is obtuse at the apex, each groove ( 15 ) having a depth H, measured on a level with the standing plane ( 12 ) between it and the bottom of the groove ( 15 ), such that:

where D is an overall transverse dimension of the bottom ( 6 ), measured at its junction with the body ( 5 ).

2 . Container ( 1 ) according to claim 1 , wherein the angle A at the apex between the sides ( 17 ) is between 90° and 150°.

3 . Container ( 1 ) according to claim 2 , wherein the angle A at the apex between the sides ( 17 ) is about 120°.

4 . Container ( 1 ) according to claim 1 , wherein each side ( 17 ) exhibits a concavity turned toward the exterior of the container ( 1 ).

5 . Container ( 1 ) according to claim 1 , wherein the depth of the groove ( 15 ) is such that

6 . Container ( 1 ) according to claim 1 , wherein the sides ( 17 ) bordering the same groove ( 15 ) define, in a plane parallel to the standing plane ( 12 ), a maximum angular opening B, measured on the axis (X) of the body ( 5 ), greater than the angular opening C defined by the apex ( 11 ) of each foot ( 7 ), measured in the standing plane ( 12 ) on the axis (X) of the body ( 5 ).

7 . Container ( 1 ) according to claim 6 , wherein the maximum angular opening B of the sides ( 17 ) is such that

8 . Container ( 1 ) according to claim 1 , wherein the bottom ( 6 ) of the container exhibits two concentric regions, namely a central region ( 18 ) and a peripheral region ( 19 ), separated by a median axial step ( 20 ) that extends annularly in a continuous manner, such that the central region ( 18 ) is axially offset in relation to the peripheral region ( 19 ) toward the interior of the container ( 1 ).

9 . Container ( 1 ) according to claim 1 , wherein the grooves ( 15 ) extend beyond the standing plane ( 12 ) onto an outer lateral wall ( 13 ) of the bottom.

10 . Container ( 1 ) according to claim 2 , wherein each side ( 17 ) exhibits a concavity turned toward the exterior of the container ( 1 ).

11 . Container ( 1 ) according to claim 3 , wherein each side ( 17 ) exhibits a concavity turned toward the exterior of the container ( 1 ).

12 . Container ( 1 ) according to claim 2 , wherein the depth of the groove ( 15 ) is such that
