the bottom (3) includes a central dome (5), whose concave part is turned towards the outside of the container (1); each groove (17) has an inner section (17A) that projects radially from the valley (12) and overlaps the dome (5), and an outer section (17B) that extends radially in the continuity of the inner section (17A), at the bottom of the respective valley (12). ## Claims ### Claim 1 A container (1) made of plastic material comprising a body (2) and a petaloid-shaped bottom (3) extending the body (2), the petaloid-shaped bottom (3) comprising a bottom wall (4) of general convex shape toward the outside, from which feet (7) formed by protrusions project, separated two at a time by portions of the bottom wall forming recessed valleys (12) that extend radially to a periphery (8) of the petaloid-shaped bottom (3), the petaloid-shaped bottom (3) further comprising a series of radial extension grooves (17) that extend at least partially at the bottom of the recessed valleys (12), wherein: the feet (7) extend axially over a height (D) that is less than or equal to 1/5 of a radial extension (A) of the petaloid-shaped bottom (3), the height (D) being measured axially from a standing plane (10) to the periphery (8) of the petaloid-shaped bottom (3); the petaloid-shaped bottom (3) comprises a central dome (5) with concavity turned toward the outside of the container (1); each of the series of radial extension grooves (17) has an inner section (17A) that radially goes beyond a respective one of the recessed valleys (12) and straddles the central dome (5), and an outer section (17B) that extends radially in the continuation of the inner section (17A), at the bottom of the respective one of the recessed valleys (12), wherein the inner section (17A) of the of the series of radial extension grooves (17) has a width greater than the outer section (17B), wherein each of the series of radial extension grooves (17) ends on the outside by a pointed outer end (18), and wherein the outer ends (18) of each of the series of radial extension grooves (17) are placed in a circle that has a diameter (J) that is less than a radial extension (C) of a standing plane (10) defined by apexes (9) of the feet (7). ### Claim 2 (depends on 1) The container (1) according to claim 1, wherein each of the series of radial extension grooves (17) has a contour that is tapering from the inside to the outside of the petaloid-shaped bottom (3). ### Claim 3 (depends on 1) The container (1) according to claim 1, wherein each of the series of radial extension grooves (17)has a depth that gradually decreases from the inside to the outside of the petaloid-shaped bottom (3). ### Claim 4 (depends on 1) The container (1) according to claim 1, wherein each of the recessed valleys ends on the inside at an inner end that is separate from the central dome. ### Claim 5 (depends on 1) The container (1) according to claim 1, wherein the central dome (5) has a radial extension that is greater than or equal to one-fifth of the radial extension of the petaloid-shaped bottom (3). ### Claim 6 (depends on 1) The container (1) according to claim 1, wherein the central dome (5) has a rise that is greater than or equal to one-half of a height of the bottom. ### Claim 7 (depends on 1) The container (1) according to claim 1, wherein the feet (7) have sides (16) that border the recessed valleys (12) and that have an angular opening (F, G) that gradually decreases from the inside to the outside of the petaloid-shaped bottom (3). ### Claim 8 (depends on 3) The container (1) according to claim 3, wherein each of the series of radial extension grooves (17) has a contour that is tapering from the inside to the outside of the petaloid-shaped bottom (3). ### Claim 9 A container (1) made of plastic material comprising a body (2) and a petaloid-shaped bottom (3) extending the body (2), the petaloid-shaped bottom (3) comprising a bottom wall (4) of general convex shape toward the outside, from which feet (7) formed by protrusions project, separated two at a time by portions of the bottom wall forming recessed valleys (12) that extend radially to a periphery (8) of the petaloid-shaped bottom (3), the bottom (3) further comprising a series of radial extension grooves (17) that extend at least partially at the bottom of the recessed valleys (12), wherein, the feet (7) extend axially over a height (D) that is less than or equal to 1/5 of a radial extension (A) of the petaloid-shaped bottom (3), the height (D) being measured axially from a standing plane (10) to the periphery (8) of the petaloid-shaped bottom (3); the petaloid-shaped bottom (3) comprises a central dome (5) with concavity turned toward the outside of the container (1); each of the series of radial extension grooves (17) has an inner section (17A) that radially goes beyond a respective one of the recessed valleys (12) and straddles the central dome (5), and an outer section (17B) that extends radially in the continuation of the inner section (17A), at the bottom of the respective one of the recessed valleys (12), wherein each of the series of radial extension grooves (17) has a contour that is tapering from the inside to the outside of the petaloid-shaped bottom (3), wherein each of the series of radial extension grooves (17) ends on the outside by a pointed outer end (18), and wherein the outer ends (18) each of the series of radial extension grooves (17) are placed in a circle that has a diameter (J) that is less than a radial extension (C) of a standing plane (10) defined by apexes (9) of the feet (7). ### Claim 10 (depends on 9) The container (1) according to claim 9, wherein each of series of radial extension grooves (17) has a depth that gradually decreases from the inside to the outside of the petaloid-shaped bottom (3). ### Claim 11 (depends on 9) The container (1) according to claim 9, wherein each of the recessed valleys ends on the inside at an inner end that is separate from the central dome. ### Claim 12 (depends on 9) The container (1) according to claim 9, wherein the central dome (5) has a radial extension that is greater than or equal to one-fifth of the radial extension of the petaloid-shaped bottom (3). ### Claim 13 (depends on 9) The container (1) according to claim 9, wherein the central dome (5) has a rise that is greater than or equal to one-half of a height of the bottom. ### Claim 14 (depends on 9) The container (1) according to claim 9, wherein the feet (7) have sides (16) that border the recessed valleys (12) and that have an angular opening (F, G) that gradually decreases from the inside to the outside of the petaloid-shaped bottom (3).
