Abstract

A container made of plastic material, provided with a body and a bottom extending at a lower end of the body, the bottom including an annular seat extending substantially in the prolongation of the body and defining a seating plane; a concave arch that extends from a zone near the seat to a central zone, the arch including a series of stiffeners that extend radially from the central zone to the seat.

First claim

The invention claimed is:

1. A container made of plastic material, provided with a body and a bottom extending at a lower end of the body, the bottom comprising:
an annular seat extending substantially in the prolongation of the body and defining a seating plane;
a concave arch that extends from a zone near the seat to a central zone;
wherein the arch comprises a series of stiffeners that extend radially from the central zone to an inner annular cheek substantially perpendicular to the seating plane; the seating plane is connected toward the interior at the cheek by a fillet, the stiffeners become thinner from their inner end to their outer end; and wherein the stiffeners extend into the annular cheek to the seat; and
wherein the bottom comprises an annular reinforcing lip at a junction between the seat and the arch, joining the outer radial ends of the stiffeners two by two.

2. The container according to claim 1 , wherein the bottom has a junction face in the shape of a truncated cone, between the arch and the cheek.

3. The container according to claim 1 , wherein the axial dimension of the cheek and the radial dimension of the seating plane are equivalent.

4. The container according to claim 1 , wherein the stiffeners together form a star-shaped motif.

5. The container according to claim 1 , wherein the arch comprises recessed panels between the stiffeners, and wherein each stiffener comprises on lateral edges of the stiffener double radius connection fillets with the panels.

6. The container according to claim 1 , wherein the seating plane is continuous.

7. A container made of plastic material, provided with a body and a bottom extending at a lower end of the body, the bottom comprising:
an annular seat defining a seating plane of the container;
a fillet directly connected to an inner radial edge of the annular seat on an outward radial edge of the fillet;
an upwardly extending cheek directly connected to the fillet on an inward radial edge of the fillet, and the cheek substantially perpendicular to the seating plane;
a concave arch that extends from a central zone of the bottom toward the seat;
wherein the arch comprises a series of stiffeners that extend radially from the central zone towards and into the cheek; and
wherein the bottom comprises an annular reinforcing lip at a junction between the seat and the arch, joining respective outer radial ends of the stiffeners two by two.

8. The container according to claim 1 , wherein the stiffeners become thinner from respective inner ends of the stiffeners to the respective outer ends of the stiffeners.

9. The container according to claim 1 , wherein the stiffeners extend to the seat.
