A thermoplastic container (1) having a body (2) provided with at least one groove (6) that forms a closed loop and that extends perpendicularly to the axis of the body; the groove having a depth (p) that lies in the range 3 mm to 6 mm; in right section, the groove comprises: an bottom (8) that is rounded, having a small radius of curvature (R1) in the range 0.2 mm to 1.5 mm; two faces (9) that are plane and that flare apart from each other on either side of the bottom (8) at an angle (α) in the range 50° to 90°; and two faces (10) that are curvilinear, and that extend away from the respective plane faces (9) at an angle (β) that is less than 180°, and that are connected thereto by respective rounded walls (11) of small radius of curvature (R2) that does not exceed 1.5 mm, and that are connected tangentially to the wall (12) of the body (2). Such a groove (6) is deformable with a capacity to pinch axially in the presence of an axial force applied to the container.

The invention claimed is: 1. A container, in particular a bottle, made of thermoplastic material such as PET, and including a body having a wall and provided with at least one peripheral closed-loop designed groove that extends in a plane that is substantially perpendicular to the axis of the body,
The invention claimed is: 1. A container, in particular a bottle, made of thermoplastic material such as PET, and including a body having a wall and provided with at least one peripheral closed-loop designed groove that extends in a plane that is substantially perpendicular to the axis of the body, wherein the groove possesses a depth (p) that lies in the range about 3 mm to 6 mm, and wherein, in a transverse section, the groove comprises: a bottom that is substantially rounded, having a relatively small radius of curvature that lies in the range 0.2 mm to 1.5 mm; two faces that are substantially plane and that flare apart from each other on either side of said bottom, forming between them an angle that lies in the range about 50° to 90°; and two faces that are curvilinear, and connected at one end to a respective plane face, and which extend away from their respective plane face in a direction different from the direction of the plane face, such that an angle formed at the connection between the plane face and the curvilinear face is substantially less than 180°, and wherein the plane face and curvilinear face are connected thereto by respective rounded walls of relatively small radius of curvature that does not exceed 1.5 mm, and wherein the other end of each curvilinear face is connected substantially tangentially to the wall of the body; whereby the groove is an axially deformable groove that possesses a capacity to pinch axially in the presence of an axial force applied to the container. 2. A container according to claim 1, wherein the depth of the deformable groove is about 4 mm. 3. A container according to claim 1, wherein the bottom of the deformable groove has a radius of curvature of about 0.5 mm. 4. A container according to claim 1, wherein the plane faces of the deformable groove form between them an angle that lies in the range about 60° to 80°. 5. A container according to claim 4, wherein the plane faces of the deformable groove form between them an angle of about 70°. 6. A container according to claim 1, wherein the rounded wall between the plane faces and the curvilinear faces possesses a radius of curvature that lies in the range about 0.8 mm to 1.2 mm. 7. A container according to claim 6, wherein the rounded wall between the plane faces and the curvilinear faces possesses a radius of curvature of about 1 mm. 8. A container according to claim 1, including a plurality of deformable grooves that are spaced apart axially from one another. 9. A container according to claim 8, wherein at least some of the deformable grooves are disposed one after another. 10. A container according to claim 8, wherein at least one non-deformable groove is interposed between at least some of the deformable grooves. 11. A container according to claim 10, wherein the deformable grooves alternate with non-deformable grooves. 12. A container according to claim 8, wherein a small number of the deformable grooves are grouped together in one portion of the body of the container, and wherein the remainder of the body does not have grooves. 13. A container, in particular a bottle, made of thermoplastic material such as PET, and including a body having a wall and provided with at least one peripheral closed-loop designed groove and that extends in a plane that is substantially perpendicular to the axis of the body, wherein the groove possesses a depth (p) that lies in the range about 3 mm to 6 mm, and wherein, in a transverse section, the groove comprises: a bottom that is substantially rounded without a flat bottom portion, having a relatively small radius of curvature that lies in the range 0.2 mm to 1.5 mm; two faces that are substantially plane and that flare apart from each other on either side of said bottom, forming between them an angle that lies in the range about 50° to 90°; and two faces that are curvilinear, and connected at one end to a respective plane face, and which extend away from their respective plane face in a direction different from the direction of the plane face, such that an angle formed at the connection between the plane face and the curvilinear face is substantially less than 180°, and wherein the plane face and curvilinear face are connected thereto by respective rounded walls of relatively small radius of curvature that does not exceed 1.5 mm, and wherein the other end of each curvilinear face is connected substantially tangentially to the wall of the body; whereby the groove is an axially deformable groove that possesses a capacity to pinch axially in the presence of an axial force applied to the container. 14. A container according to claim 13, wherein the cross-sectional shape of the groove is V-shaped. 15. A container according to claim 1, wherein the cross-sectional shape of the groove is V-shaped.
