A plastic bottle that can easily be collapsed after used is provided. The plastic bottle has a body portion that is depressed internally by applying external force, and a depressible portion formed on a circumferential wall of the body portion to protrude externally. The depressible portion is depressed internally by applying external force. Plural depressible portions and plural depression-resistant portions may be formed alternately on the circumferential wall of the body portion in the circumferential direction of the body portion.

The invention claimed is: 1. A plastic bottle having a body portion that collapses internally when an external force is applied, comprising: at least one depressible portion formed on a circumferential wall of the body portion to protrude externally, the at least one depressible portion being depressed internally when the external force is applied, depression-resistant portions formed on the circumferential wall of the body portion, the depression-resistant portions being adjacent to the at least one depressible portion, the depression-resistant portions being configured to resist depression from the external force, the depression-resistant portions including a plurality of first depression-resistant portions extending in a direction of a central axis of the plastic bottle and a plurality of second depression-resistant portions extending in a circumferential direction of the body portion, wherein at least one of the plurality of second depression-resistant portions integrally joins an upper edge of at least one of the plurality of first depression-resistant portions, wherein at least one of the plurality of second depression-resistant portions integrally joins a middle point of at least one of the plurality of first depression-resistant portions, wherein at least one of the plurality of second depression-resistant portions integrally joins a lower edge of at least one of the plurality of first depression-resistant portions, and wherein when the at least one depressible portion is depressed internally, the plurality of first and second depression-resistant portions form a maximum perimeter of the plastic bottle. 2. The plastic bottle according to claim 1, wherein a plurality of depressible portions and the plurality of first depression-resistant portions are formed alternately in a circumferential direction of the body portion. 3. The plastic bottle according to claim 2, wherein the plurality of depressible portions and the plurality of second depression-resistant portions are formed alternately in the direction of the central axis of the plastic bottle. 4. The plastic bottle according to claim 2 or 3, wherein when the plurality of depressible portions are depressed internally, the plurality of depressible portions end up closer to the central axis of the plastic bottle than the depression-resistant portions. 5. The plastic bottle according to claim 2, wherein the plurality of depressible portions are configured not to interfere with each other in the body portion when the plurality of depressible portions are depressed internally. 6. The plastic bottle according to claim 1, wherein the at least one depressible portion includes: an externally protruding section, and a top section, wherein the externally protruding section is inclined and continues to a periphery of the top section. 7. The plastic bottle according to claim 1, wherein the at least one depressible portion comprises: a top section that protrudes externally the most, and a protruding section that continues into the periphery of the top section, wherein the top section is curved to have its center of curvature inside the plastic bottle. 8. The plastic bottle according to claim 7, wherein the top section extends in the direction of the central axis of the plastic bottle. 9. A plastic bottle having a body portion that collapses internally when an external force is applied, comprising: a plurality of depressible portions formed on a circumferential wall of the body portion, the plurality of depressible portions being depressed internally when the external force is applied a plurality of first depression-resistant portions formed on the circumferential wall of the body portion, the plurality of first depression-resistant portions being adjacent to the plurality of depressible portions, the plurality of first depression-resistant portions being configured to resist depression from the external force, the plurality of first depression-resistant portions extending in a circumferential direction of the body portion, a plurality of second depression-resistant portions formed on the circumferential wall of the body portion, the plurality of second depression-resistant portions being adiacent to the plurality of depressible portions, the plurality of second depression-resistant portions being configured to resist depression from the external force, the plurality of second depression-resistant portions extending in a direction of a central axis of the plastic bottle, wherein the plurality of first depression-resistant portions and the plurality of second depression-resistant portions define a perimeter of each of the plurality of depressible portions, wherein at least one of the first depression-resistant portions divide the plastic bottle into an upper portion and a lower portion, wherein when the plurality of depressible portions are depressed internally, the plurality of first depression-resistant portions and the plurality of second depression-resistant portions form a maximum perimeter of the plastic bottle. 10. The plastic bottle according to claim 9, wherein the plurality of depressible portions and the plurality of second depression-resistant portions are formed alternately in the circumferential direction of the body portion. 11. The plastic bottle according to claim 10, wherein the plurality of depressible portions and the plurality of first depression-resistant portions are formed alternately in the direction of the central axis of the plastic bottle. 12. The plastic bottle according to claim 10 or 11, wherein when the plurality of depressible portions are depressed internally, the plurality of depressible portions end up closer to the central axis of the plastic bottle than the plurality of first depression-resistant portions and the plurality of second depression-resistant portions. 13. The plastic bottle according to claim 10, wherein the plurality of depressible portions are configured not to interfere with each other in the body portion when the plurality of depressible portions are depressed internally. 14. The plastic bottle according to claim 9, wherein each of the plurality of depressible portions include: an externally protruding section, and a top section, wherein the externally protruding section is inclined and continues to a periphery of the top section. 15. The plastic bottle according to claim 9, wherein each of the plurality of depressible portions comprise: a top section that protrudes externally the most, and a protruding section that continues into the periphery of the top section, wherein the top section is curved to have its center of curvature inside the plastic bottle. 16. The plastic bottle according to claim 15, wherein the top section extends in the direction of the central axis of the plastic bottle.
