## Abstract

The invention relates to a container made of a plastic material, provided with a body (5) and a bottom (6) extending at a lower end of the body (5), wherein the bottom (6) includes: an annular seat (7) extending substantially away from the body (5) and defining a support surface (8) and an inner annular flange (11) substantially perpendicular to the support surface; a concave arch (13) which extends from an area adjacent to the seat (7) towards a central area (14). The axial dimension H of the flange and the radial dimension L of the support surface are such that: formula (I). 0 , 6 ≤ L H ≤ 1 , 5 ( I )

## Claims

### Claim 1

A container (1) of plastic material, having a body (5) and a bottom (6) extending at a lower end of the body (5), the bottom (6) comprising:
an annular seat (7) extending substantially in the prolongation of the body (5) and defining a seating plane (8), and an inner annular cheek (11) substantially perpendicular to the seating plane;
a concave arch (13) that extends from the zone near the seat (7) to the central zone (14);
characterized in that the axial dimension H of the cheek and the radial dimension L of the seating plane are such that:

H
≤
1.2

### Claim 3 (depends on 1)

The container (1) according to claim 1, characterized in that the axial dimension (H) of the cheek (11) and the radial dimension (L) of the seating plane (8) are substantially equal.

### Claim 4 (depends on 1)

The container according to claim 1, comprising:
a series of stiffeners (17) that extend radially from the central zone (14) to the seat (7);
a junction face (16) between the arch (13) and the cheek (11);
a peripheral series of curved surfaces (28) projecting inwards from the junction (16) face between the stiffeners (17).

### Claim 5 (depends on 4)

The container according to claim 4, characterized in that the junction face (16) is a truncated cone and has a predetermined angular opening (A2).

### Claim 6 (depends on 5)

The container according to claim 5, characterized in that each curved surface (28) locally modifies the angular opening (A2) of the junction face (16).

### Claim 7 (depends on 6)

The container according to claim 6, characterized in that each curved surface (28) locally reduces the angular opening (A2) of the junction face (16).

### Claim 8 (depends on 6)

The container according to claim 6, characterized in that each curved surface (28) locally increases the angular opening (A2) of the junction face (16).

### Claim 9 (depends on 4)

The container according to claim 4, characterized in that each curved surface (28) has an arched inner edge (29) that overlaps the arch (13).

### Claim 10 (depends on 4)

The container according to claim 4, characterized in that each curved surface (28) has lateral edges (31) that are non-parallel.
