[0030]
Next, a bottle crushing method will be described with reference to the drawings.
In crushing the bottle after use, with the opening / closing lid B2 of the cap B opened, the bottle is placed on the desk with the handle on the right side of the bottle and crushed. (When the bottle is placed on the desk, the left and right sides of the bottle axis are up and down, and the front and back are left and right.
[0031]
In crushing, first, the bottle mouth part 1 or the body part 2 is pressed and the front side of the intermediate part in the longitudinal direction of the handle 4 is pressed.
When a bending force is applied to the handle 4, the handle 4 is bent and inclined at the lower rib 23, and is bent toward the trunk at the lower portion of the step wall 22 of the intermediate bulging portion 21.
[0032]
Next, when the upper portion of the barrel wall 30 is pressed, a bending force acts between the right side portion of the bulging circumferential wall 11 and the right circumferential surface 30b of the barrel wall 30, and as shown in FIG. 9, the right circumferential surface 30b. Is bent with the arc-shaped ribs 34 as folds, and the right side portion of the bulging peripheral wall 11 is bent downward.
[0033]
Next, when the lower portion of the barrel wall 30 is pressed, the lower portion of the right peripheral surface 30b is bent with the lateral rib 35 as a crease, and the bottom peripheral wall 31 is inclined accordingly.
And the left side peripheral surface 30a and the right side peripheral surface 30b of the trunk cylinder wall 30 are bent around the vertical rib 32 so that the trunk cylinder wall 30 is flattened, and the vertical rib 32 projects forward and backward accordingly. Become.
[0034]
The flattening of the trunk cylinder wall 30 affects the trunk peripheral wall 10 of the upper trunk portion 7. Since the front and rear walls 16 are difficult to bend in the transverse direction by the lateral ribs 19 extending from the curved wall 14, the trunk peripheral wall 10 is bent at the connecting edges 17 a and 17 b between the inclined walls 15 b and c and the front and rear walls 16. Swells in the front-rear direction.
[0035]
Next, when the bottom portion 3 is bent upward, the bottom portion 3 is bent by the lateral rib 35 of the right peripheral surface 30b, and the right peripheral surface 30b and the right portion of the bottom peripheral wall 31 become a continuous surface, and the bottom wall 40 is further inclined. To do.
Thus, the body 2 becomes a flat body 2a, and a flat bottle as shown in FIG. 10 can be obtained.
At that time, plastic deformation is caused in other portions as well as the bent and bulged portions, the flat state is maintained, and it can be discarded in this state.
[0036]
Next, holding the mouth part 1 and the bottom part 3, bending the whole bottle and applying a moment between the mouth part 1 and the bottom part 3, as shown in FIG. 11, the bottom part 3 is further pressed and flattened. Thus, the trunk peripheral wall 10 is bent with the lateral rib 19 as an axis, and the handle 4 is bent accordingly.
The handle 4 is further bent at the portions of the lower rib 23 and the step wall 22, and the lower end portion of the step wall 22 widens the intermediate bulge portion 21 in the width direction to cause plastic deformation. Is flattened so that the back surface of the stepped wall 22 is brought into contact with the curved wall 14 of the waist wall 10.
[0037]
Next, when the moment M is further applied and the mouth portion 1 and the bottom portion 3 are rounded, the upper and lower portions of the flat barrel portion 2a are further bent, and the bottom wall 40 approaches the knob 64 of the cap B opening / closing lid B2. Can be curved until
Next, when the hooking piece 43 provided on the bottle bottom wall 40 is inserted into the locking hole 65 of the picking piece 64 of the opening / closing lid B2 and the hand is released, the hook part 42 is picked up by the restoring force of the flat body 2a. 64 is caught by the back surface, and the engagement state between the bottom 3 of the bottle and the mouth 1 is maintained.
[0038]
In flat crushing, the flat barrel portion 2a is plastically deformed and is not restored unless an external force is applied. However, the curvature of the flat barrel portion 2a may not lead to plastic deformation. By locking, the flat barrel portion 2a that is curved and rounded at the time of disposal is prevented from being restored.
Thus, the waste bottle as shown in FIG. 12 can be a waste bottle rounded to a very small capacity.
[0039]
As mentioned above, when crushing by placing the handle on the right side of the bottle and crushing it, just pressing from the top (right side) of the bottle, the pressing force acts as the reaction on the left side, so crushing is efficient However, it is also possible to squeeze by holding the bottle with both hands and pressing sequentially from the left and right according to the crushing method described above.

As a result, the latching portion 133 moves toward the outside, and the locking member 130 can be rotated around the coupling portion 131 to the outside of the opening / closing lid B2b.
Next, when the latching portion 133 is picked and turned upside down, the latching member 130 is folded at the connecting piece 132a and is inverted, and thereafter the state is maintained regardless of the opening / closing of the opening / closing lid B2b. Can do.
[0066]
For disposal after use, the bottle is flattened with the open / close lid B2b open, and then the flattened flat bottle 2a is rolled up so that the bottom 3A of the bottle approaches the open / close lid B2b, When 43 is inserted into the locking member 130, the latching piece 43 pulls the latching portion 133 by the restoring force of the flat body 2 a, and the arcuate locking member 130 becomes triangular and engages with the latching piece 43. The engagement state between the bottle bottom 3A and the cap Bb is maintained, and a rounded waste bottle can be obtained as shown in FIG.
