<p>PROBLEM TO BE SOLVED: To completely squeeze a whole bottle by continuously providing two V-shaped inclined ribs and a vertical rib on a shoulder circumferential wall, continuously providing a vertical rib and two V-shaped inclined ribs on a body circumferential wall, and arranging a horizontal rib a connection part of the shoulder circumferential wall to the body circumferential wall to flatten a body part and fold it. SOLUTION: A bottle comprises a mouth cylindrical part 1, a shoulder circumferential wall 2, a body circumferential wall 3 and a bottom wall 4. V-shaped inclined ribs 9 and a vertical rib 10 are continuously provided on a pyramidal part 7 and a square cylindrical part 8 of the shoulder circumferential wall 2 to form a Y-shaped rib on the whole, and a horizontal rib 11 is arranged between the shoulder circumferential wall 2 and the body circumferential wall 3. A horizontal rib 14 is arranged between upper and lower body parts 12, 13 of the body circumferential wall 3, and a vertical rib 15 and V-shaped inclined ribs 18 are continuously provided on the upper and lower body parts 12, 13 to form an inverted Y-shaped rib on the whole. The right and left side surfaces of the shoulder circumferential wall 2 and the body circumferential wall 3 are inwardly folded with the respective vertical ribs 10, 15 as folding lines, the lower body part 13 is bent, and then, the flattened body part and the deformed bottom part are folded to squeeze the bottle.</p> |
