Abstract

A bottle can has a curl part at an opening end of a mouth part thereof. The curl part has an upper end curved part in which an upper part of a neck shoulder part of the mouth part is curved outward and an outer wall part extending downward from the upper end curved part. A predetermined angle at which an outer edge side of a lower end face of the outer wall part opens is formed between the lower end face of the outer wall part and the neck shoulder part. An inner edge of the lower end face comes into contact with the neck shoulder part when a downward load is applied to the curl part from above.

First claim

The invention claimed is:

1. A bottle can having a curl part at an opening end of a mouth part thereof, wherein
the curl part has an upper end curved part in which an upper part of a neck shoulder part of the mouth part is curved outward and an outer wall part extending downward from the upper end curved part,
a predetermined angle at which an outer edge side of a lower end face of the outer wall part opens is formed between the lower end face of the outer wall part and the neck shoulder part, and
an inner edge of the lower end face comes into contact with the neck shoulder part when a downward load is applied to the curl part from above.

2. The bottle can according to claim 1 , wherein the angle is 10° to 90°.

3. The bottle can according to claim 1 , wherein a gap between the inner edge and the neck shoulder part is 0.3 mm or less before deformation.

4. The bottle can according to claim 2 , wherein a gap between the inner edge and the neck shoulder part is 0.3 mm or less before deformation.

5. The bottle can according to claim 1 , wherein the inner edge is in contact with the neck shoulder part at all times.

6. The bottle can according to claim 2 , wherein the inner edge is in contact with the neck shoulder part at all times.

7. The bottle can according to claim 1 , wherein the upper end curved part has an inner curved part and an outer curved part, and a radius of curvature of the inner curved part is greater than a radius of curvature of the outer curved part.

8. The bottle can according to claim 2 , wherein the upper end curved part has an inner curved part and an outer curved part, and a radius of curvature of the inner curved part is greater than a radius of curvature of the outer curved part.

9. The bottle can according to claim 3 , wherein the upper end curved part has an inner curved part and an outer curved part, and a radius of curvature of the inner curved part is greater than a radius of curvature of the outer curved part.

10. The bottle can according to claim 4 , wherein the upper end curved part has an inner curved part and an outer curved part, and a radius of curvature of the inner curved part is greater than a radius of curvature of the outer curved part.

11. The bottle can according to claim 5 , wherein the upper end curved part has an inner curved part and an outer curved part, and a radius of curvature of the inner curved part is greater than a radius of curvature of the outer curved part.

12. The bottle can according to claim 6 , wherein the upper end curved part has an inner curved part and an outer curved part, and a radius of curvature of the inner curved part is greater than a radius of curvature of the outer curved part.

13. The bottle can according to claim 7 , wherein the radius of curvature of the inner curved part is 0.5 mm to 2 mm, and the radius of curvature of the outer curved part is 0.3 to 0.8 mm.

14. The bottle can according to claim 8 , wherein the radius of curvature of the inner curved part is 0.5 mm to 2 mm, and the radius of curvature of the outer curved part is 0.3 to 0.8 mm.

15. The bottle can according to claim 9 , wherein the radius of curvature of the inner curved part is 0.5 mm to 2 mm, and the radius of curvature of the outer curved part is 0.3 to 0.8 mm.

16. The bottle can according to claim 10 , wherein the radius of curvature of the inner curved part is 0.5 mm to 2 mm, and the radius of curvature of the outer curved part is 0.3 to 0.8 mm.

17. The bottle can according to claim 11 , wherein the radius of curvature of the inner curved part is 0.5 mm to 2 mm, and the radius of curvature of the outer curved part is 0.3 to 0.8 mm.

18. The bottle can according to claim 12 , wherein the radius of curvature of the inner curved part is 0.5 mm to 2 mm, and the radius of curvature of the outer curved part is 0.3 to 0.8 mm.

19. A bottle can with a cap against which a cap having a liner material for covering the curl part in the bottle can according to claim 1 is tightly screwed.
