Abstract

A plastic container ( 1 ) is provided with a body ( 5 ) and a bottom ( 6 ) that extends from a lower end of the body ( 5 ), the bottom ( 6 ) including: a peripheral base ( 7 ) defining a bearing surface ( 8 ); a concave arch ( 10 ) that extends from a central zone ( 11 ) to the base ( 7 ); and a series of main reinforcing grooves ( 13 ) hollowed into the arch, extending radially from the central zone ( 11 ) at least to the base ( 7 ) and dividing the arch into a series of angular sectors ( 15 ). Where each groove ( 13 ) joins each sector ( 15 ) of the arch ( 10 ) adjacent thereto it is bordered laterally by a reinforcing rib ( 18 ) projecting in relation to the sector ( 15 ).

First claim

1 . Container ( 1 ) made of plastic material, provided with a body ( 5 ) and with a bottom ( 6 ) extending from a lower end of the body ( 5 ), the bottom ( 6 ) comprising:
a peripheral base ( 7 ) defining a standing plane ( 8 ); a concave arch ( 10 ) that extends from a central area ( 11 ) to the base ( 7 ); a series of main reinforcing grooves ( 13 ), formed recessed in the arch, which extend radially from the central area ( 11 ) to the base ( 7 ) at least, and which subdivide the arch into a series of angular sectors ( 15 ),
wherein each main groove ( 13 ) is bordered laterally, at its junction with each angular sector ( 15 ) of the arch ( 10 ) that is adjacent to it, by a reinforcing rib ( 18 ) that extends projecting in relation to said sector ( 15 ).

2 . Container ( 1 ) according to claim 1 , wherein each main groove ( 13 ) has a bottom ( 16 ) flanked by two lateral walls ( 17 ), and wherein each reinforcing rib ( 18 ) extends into the extension of a lateral wall ( 17 ).

3 . Container ( 1 ) according to claim 1 , wherein each reinforcing rib ( 18 ) extends inwardly to the central area ( 11 ).

4 . Container ( 1 ) according to claim 1 , wherein the bottom ( 6 ) of the container comprises an annular ledge ( 9 ) that extends approximately perpendicular to the standing plane ( 8 ) and forms the junction between it and a peripheral edge of the arch ( 10 ).

5 . Container ( 1 ) according to claim 1 , wherein each reinforcing rib ( 18 ) extends outwardly to the standing plane ( 8 ).

6 . Container ( 1 ) according to claim 4 , wherein at its junction with the standing plane ( 8 ), each reinforcing rib ( 18 ) lies flush with it.

7 . Container ( 1 ) according to claim 1 , wherein the reinforcing ribs ( 18 ) located on both sides of the same angular sector ( 15 ) extend into the continuity of one another.

8 . Container ( 1 ) according to claim 1 , wherein the bottom ( 6 ) of the container has, on the inside of the standing plane ( 8 ), two concentric regions, namely a central region ( 22 ) and a peripheral region ( 23 ), separated by a median axial step ( 24 ) that extends annularly in a continuous manner, at the same time on the angular sectors ( 15 ) of the arch ( 10 ), the main grooves ( 13 ) and the reinforcing ribs ( 18 ), around the central area ( 11 ), such that the central region ( 22 ) is offset axially in relation to the peripheral region ( 23 ) toward the interior of the container ( 1 ).

9 . Container ( 1 ) according to claim 1 , wherein the main reinforcing grooves ( 13 ) extend radially beyond the base ( 7 ).

10 . Container ( 1 ) according to claim 1 , wherein the bottom ( 6 ) of the container comprises a series of intermediate reinforcing grooves ( 14 ), which extend locally astride the base ( 7 ).

11 . Container ( 1 ) according to claim 2 , wherein each reinforcing rib ( 18 ) extends inwardly to the central area ( 11 ).

12 . Container ( 1 ) according to claim 2 , wherein the bottom ( 6 ) of the container comprises an annular ledge ( 9 ) that extends approximately perpendicular to the standing plane ( 8 ) and forms the junction between it and a peripheral edge of the arch ( 10 ).

13 . Container ( 1 ) according to claim 3 , wherein the bottom ( 6 ) of the container comprises an annular ledge ( 9 ) that extends approximately perpendicular to the standing plane ( 8 ) and forms the junction between it and a peripheral edge of the arch ( 10 ).

14 . Container ( 1 ) according to claim 2 , wherein each reinforcing rib ( 18 ) extends outwardly to the standing plane ( 8 ).

15 . Container ( 1 ) according to claim 3 , wherein each reinforcing rib ( 18 ) extends outwardly to the standing plane ( 8 ).

16 . Container ( 1 ) according to claim 4 , wherein each reinforcing rib ( 18 ) extends outwardly to the standing plane ( 8 ).

17 . Container ( 1 ) according to claim 2 , wherein the reinforcing ribs ( 18 ) located on both sides of the same angular sector ( 15 ) extend into the continuity of one another.

18 . Container ( 1 ) according to claim 2 , wherein the bottom ( 6 ) of the container has, on the inside of the standing plane ( 8 ), two concentric regions, namely a central region ( 22 ) and a peripheral region ( 23 ), separated by a median axial step ( 24 ) that extends annularly in a continuous manner, at the same time on the angular sectors ( 15 ) of the arch ( 10 ), the main grooves ( 13 ) and the reinforcing ribs ( 18 ), around the central area ( 11 ), such that the central region ( 22 ) is offset axially in relation to the peripheral region ( 23 ) toward the interior of the container ( 1 ).

19 . Container ( 1 ) according to claim 2 , wherein the main reinforcing grooves ( 13 ) extend radially beyond the base ( 7 ).

20 . Container ( 1 ) according to claim 2 , wherein the bottom ( 6 ) of the container comprises a series of intermediate reinforcing grooves ( 14 ), which extend locally astride the base ( 7 ).
