The present invention provides synthetic resin thin-walled bottle container (10, 20, 30) including a mouth portion (11) for filling or discharging contents, a body portion (12, 22, 32) extending from the mouth portion (11) along the center axis (A) of the container, and a heel portion (H10, H20, H30
The present invention provides synthetic resin thin-walled bottle container (10, 20, 30) including a mouth portion (11) for filling or discharging contents, a body portion (12, 22, 32) extending from the mouth portion (11) along the center axis (A) of the container, and a heel portion (H10, H20, H30) provided at the bottom part (13, 23, 33) of the body portion (12, 22, 32) for placing, thereon, the body portion (12, 22, 32) in a self-supporting manner. The heel portion (H10, H20, H30, H40) includes a sidewall (14, 24, 34) formed of a curved surface (R11, R21, R31) that is recessed toward the inside of the container (10). Thus, even with a reduced amount of the resin, the container (10, 20, 30) can be stably self-supported without causing inclination or buckling at the heel portion (H10, H20, H30), under a load applied in the center axis (A) direction thereof.

The invention claimed is: 1. A synthetic resin thin-walled bottle container comprising: a mouth portion for filling or discharging contents; a body portion extending from the mouth portion; and a heel portion provided at a bottom part of the body portion, for placing therein the body portion in a self-supporting manner, the heel portion comprising: a sidewall having a curved surface that is recessed toward the inside of the container; a bottom face region formed of a curved surface that is smoothly continuous with the curved surface of the sidewall and bulged toward the outside of the container; a bottom-up region formed of a curved surface recessed inwardly toward the vicinity of the center axis of the bottle; and a rising region between the bottom face region and the bottom-up region, for continuously and smoothly connecting the curved surface of the bottom face region and the curved surface of the bottom-up region to each other; wherein the bottom face region and the rising region are bulged toward the underside of the container when the container is filled with the contents, and the bottom face region and the rising region form a flat surface that is closely contacted with a supporting surface of the container. 2. The container according to claim 1, wherein the container is molded from a resin in the amount of about 6 g, when the container has a volume of about 560 ml. 3. The container according to claim 1, wherein the synthetic resin is polypropylene. 4. The container according to claim 1, wherein the bottom face region connects the sidewall to the rising region and is in the shape of a reverse R. 5. The container according to claim 1, wherein the body portion further comprises a reinforcing portion adjacent to the mouth portion. 6. The container according to claim 5, wherein the reinforcing portion is formed in a diamond-cut pattern. 7. The container according to claim 1, wherein the body portion further comprises a gripping recess. 8. The container according to claim 1, wherein the curved surface of the sidewall has a first radius of curvature and the curved surface of the bottom face region has a second radius of curvature, which is less than the first radius of curvature.
