Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crushable plastic bottle with a handle.

[0002]

In recent years, disposal of plastic waste has become a major problem, and recycling of used plastic containers has been practiced. Further, in order to reduce the volume of the waste, the waste container is crushed. Therefore, it is recommended to separate used plastic containers from each household and to crush the containers, but plastic containers are used to store liquid contents and maintain a certain external shape to prevent damage. Since a certain strength must be provided, a considerable amount of crushing force is required to crush a used empty plastic container and reduce the volume of the container.

[0003] Therefore, at present, in general households, plastic containers are taken out of the collection place without being crushed. Therefore, the problem that the plastic waste becomes bulky and the transportation efficiency is not good cannot be solved. Further, even if the container can be easily crushed, a cap must be fitted in the crushed state to prevent the container from being restored, and the inside of the container must be kept under reduced pressure. There is also a problem that materials are mixed.

[0004] In order to solve these problems, various plastic containers which can be easily crushed have been proposed. However, a large-diameter plastic bottle having a handle has a problem that the thickness of the bottle body wall is so large that it is difficult to crush the handle and that the handle cannot be crushed. In addition, since it is difficult to deform the lower wall surface of the handle forming hole that forms the handle together with the handle, there is a problem that the volume reduction rate of the upper body cannot be increased.

The present invention has been made to solve the above problems,
First, in a large-diameter plastic bottle with a handle for storing a liquid content while maintaining a certain strength, the handle is crushed and the bottle is rounded to form a very small-capacity rounded waste bottle. In the case where the cap is made of a different material, the handle can be easily crushed as a technical problem such that the cap can be separately disposed without being covered with the cap, so that the different material is not mixed in during the regeneration process. It is intended to provide an attached plastic bottle.

[0006]

As shown in FIG. 4 and FIG.
0 and the bottom peripheral wall 31 of the body 2 formed on the periphery of the bottom wall 40
Bottom end wall 41 is provided on the parting line, and the bottom wall portion 40 is the deepest recessed portion on the parting line on the left side of the bottle axis, that is, on the opposite side to the handle.
a, and is formed of a curved surface gently continuing from the bottom surface portion 40a to the bottom end wall 41. Bottom wall 40
On the left side, has a hook 42 protruding inward at the tip,
A locking piece 43 extending substantially horizontally is provided along the parting line L. The base of the locking piece 43 is
The hook portion 42 is located close to the bottom end wall 41,

The concave portion 45 is located at a position facing the parting line L.
Are formed.

The hook 42 of the locking piece 43 is positioned so as to correspond to the deepest concave bottom 40 a of the bottom wall 40, so that a certain distance is provided between the hook 42 and the bottom wall 40. The hook 42 of the locking piece 43 is easily hooked on the mouth 1 of the bottle A when the crushed bottle described later is rounded. In addition, since the bottom surface of the bottom wall 40 is formed by a gentle curved surface and there is no corner that is easily bent,
Even when crushed, the locking piece 43 is maintained in a stable state on the bottom wall 40, and the hook portion 42 does not shake.

Next, the crushing of the bottle will be described.
First, the outline of the crushing method is as follows. When the used bottle is crushed, the crusher is placed on a desk with the handle on the right side of the bottle and the handle facing upward. (When the bottle is placed on a desk, the left and right of the bottle axis are up and down, and the front and back are left and right, but use the conventional notation as described above.) First, lightly press the body 2 and hold the mouth 1 hand,
The handle 4 is bent. Next, the lower torso portion 8 is strongly pressed from the right side, and the left and right torso walls of the lower torso portion 8 are deformed and flattened by the vertical ribs 32, and at the same time, the torso peripheral wall 10 of the upper torso portion 7 is deformed.
Is crushed flat. Next, the bottom portion 3 is rotated to obtain a flattened waste bottle. Finally, the flattened waste bottle is entirely curved, and a locking piece 43 having a hook portion 42 provided on the bottom portion 3 is locked to the upper end edge of the mouth portion 1 to obtain a rounded waste bottle. .

Next, the operation at the time of crushing based on the configuration of the bottle will be described with reference to the drawings. First, holding the body 2, holding the bottle mouth 1 and the upper part of the handle 4 and applying a bending force to the handle 4, the handle 4 is bent at the lower rib 22 and inclined as shown in FIG. 8. , Is bent below the step wall 21 of the intermediate bulging portion 20.

At the same time, the right side portion of the bulging peripheral wall 11 and the barrel wall 3
A bending force acts between the right side peripheral surface 30b and the right side peripheral surface 30b, and as shown in FIG. 8, the right side peripheral surface 30b is bent with the arcuate rib 34 as a fold, and the right side portion of the bulging peripheral wall 11 is inclined downward. Bend like so.

Next, when the barrel wall 30 of the lower barrel 8 is strongly pressed from the right side, the left peripheral surface 30a and the right peripheral surface 30b of the barrel wall 30 become vertical ribs 32a, b as shown in FIG. And the barrel wall 30 is flattened, and the vertical ribs 32a, 32b project back and forth accordingly.

The pressing of the barrel wall 30 simultaneously presses the circumferential wall 10 of the upper body 7 from the right. Front and rear wall 15
Is difficult to bend due to the lateral ribs 18 extending from the drum-shaped wall 14, so that the trunk peripheral wall 10 is
5 and bulges in the front-back direction at connection edges 16a, 16b. The lower end and the bottom 3 of the torso peripheral wall 10 are bent by the lateral ribs 35 on the right peripheral surface 30b, and the left peripheral surface 30a and the left portion of the bottom peripheral wall 31 are continuous surfaces, and the bottom wall 40 is inclined.
Thus, the torso 2 is a flat torso 2a as shown in FIG.
Thus, a flattened waste bottle can be obtained.
At that time, plastic deformation is caused not only at the bent and swollen portions but also at other places, and the flat state is maintained.

Next, when the user holds the mouth 1, the shoulder wall 9 and the bottom 3, and rotates the bottom 3 and presses it on the torso peripheral wall 10,
As shown in FIG. 10, the bottom 3 becomes flat with the angle between the flat body 2 a and the bottom 3 being changed about the horizontal rib 35 as an axis. Next, when a moment is applied between the mouth part 1 and the bottom part 3, the trunk wall 10 is bent about the horizontal rib 18, and the handle 4 is further bent accordingly. The handle 4 is bent with the lower rib 22 as an axis, and the rising wall surface of the step wall 21 presses the arc surface of the surface of the intermediate bulging portion 20 and spreads in the width direction, flattens the surface, and causes plastic deformation.

Next, a further moment is applied to the mouth 1
When the flat portion 2a and the bottom portion 3 are rolled up, the upper and lower portions of the flat body portion 2a can be further bent, and can be bent until the bottom wall 40 comes into contact with the peripheral surface of the mouth 1 side. In this state, when the hook 42 of the locking piece 43 provided on the bottom wall 40 is engaged with the inner periphery of the mouth 1, the mouth 1 and the bottom 3 can be maintained in the locked state. As shown, the flat body 2a
Can be obtained in a state where the waste bottle is rounded.

In flat crushing, the flat body 2a
Is plastically deformed and does not recover unless external force is applied. However, since the flat body portion 2a may not be deformed until plastic deformation, it is bent at the time of disposal by locking the mouth portion 1 and the bottom portion 3. The flattened trunk portion 2a that has been rounded in prevents restoration. Thus, the waste bottle can be a waste bottle rounded to a very small volume.

As described above, when the bottle is placed on a desk with the handle on the right side and the handle up, and crushed, only pressing from above (right side) of the bottle and pressing force on the left side as a reaction is applied. The crushing is done efficiently,
It is also possible to hold the bottle with both hands and crush it. In that case, the flattening of the barrel wall 30 of the lower torso portion 8, the flattening of the torso peripheral wall 10 of the upper torso portion 7 and the bending of the handle 4 are individually performed, and then the bottom portion 3 is interlocked in a counterclockwise direction.
By curving the whole, a waste bottle as shown in FIG. 11 can be obtained.

Next, another embodiment in which the positions of the bent ribs of the handle are changed will be described with reference to the drawings. FIG.
As shown in FIGS. 2 and 13, the handle 4A is connected to the shoulder wall 9A and the wall surface 19A of the peripheral edge of the bulging peripheral wall 11A from the upper end of the shoulder wall 9A and the drum-shaped wall 14A via the handle forming hole 12A facing the drum-shaped wall 14A. It is extended, and is formed in the shape of a crescent section in which the inside and the outside are arcs having different diameters.

An intermediate bulging portion 20 is provided at an intermediate portion of the handle 4A.
A is formed, and the upper front side of the intermediate bulging portion 20A is a step, and a crescent-shaped step wall 21A is provided. At the upper end of the handle 4A, a horizontal rib 50 is provided at a connection portion of the shoulder wall 9A, and an arc-shaped lower rib 51 is provided at a connection portion with the drum-shaped wall 14A. Lateral rib 50 and lower rib 51
Are connected by an arc on the upper surface of the drum-shaped wall 14A, and separate the handle 4A from the shoulder wall 9A and the drum-shaped wall 14A.

When bending the handle, handle 4
When a bending force is applied to A, the handle 4A is bent and inclined at the portion of the lateral rib 50, and the stepped wall 2 of the intermediate bulging portion 20A is formed.
It is bent below 1A. At this time, the arc portion of the horizontal rib 50 expands and the arc portion of the lower rib 51 narrows, so that the handle can be easily bent.

Next, another embodiment in which the shape of the bottom wall is changed will be described with reference to the drawings. In the above-described embodiment, the deepest concave bottom portion 40a is located on the left side of the center of the bottom wall 40, that is, at a position closer to the opposite side of the handle, but as shown in FIG. The center may be located at the axis of the bottle, and the curved surface may be a spherical surface. As shown in FIG. 3B, the bottom wall 40 is not a spherical surface, and a flat wall portion 40c having a constant radius is provided at the center. It may be a bottom wall having.

At this time, the hook portion 42 of the locking piece 43 does not necessarily need to be positioned so as to correspond to the bottom surface portion 40a, but the lower surface of the locking piece 43 is positioned inside the bottom end wall 41. A locking piece 43 must be provided. Also,
The position of the root of the locking piece 43, the shape and length of the locking piece 43,
The shape of the hook 42 can be set according to the shape of the container mouth, the length of the body, the positional relationship between the mouth and the bottom wall when crushed, and other design needs. Furthermore, the bottom end wall 41
The shape of the notch portion 44 formed in the above-mentioned portion can be appropriately set.

In each of the above embodiments, a stopper cap is used as a cap (not shown), but a screw is carved on the outer periphery of the mouth instead of a bulging ridge.
A screw cap can be used.

In each of the above embodiments, the cap base or the inner plug is unplugged so that the locking piece provided on the bottom wall is locked to the container mouth. However, the cap and the bottle are formed of the same resin. When the cap is removed, the bottle is crushed with the overcap removed without removing the cap base or the inner plug, and the bottle is squeezed with the cap or the inner tube as shown in FIGS. Good.

[0035]

Since the present invention is configured as described above, it has the following effects. By arranging the bending rib at a predetermined position on the bottle body wall, the bottle can be easily crushed and flattened. By disposing a bent rib at the upper end of the handle and providing a step wall at the middle, the handle can be bent and the volume reduction rate can be increased.

By arranging the horizontal ribs on the drum-shaped wall of the upper body, the upper body is easily bent, and the hooks of the locking pieces provided on the bottom wall are engaged with the mouth of the bottle. The large-diameter bottle with a handle could be turned into a small-capacity rounded waste bottle.
