Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a plastic bottle which can be easily crushed.

[0002]

2. Description of the Related Art In recent years, disposal of plastic waste has become a major problem, and recycling of used plastic containers has been practiced. In order to reduce the volume of waste, crushing of waste containers is encouraged. Therefore, various plastic containers that can be easily crushed have been proposed.

[0003]

However, since the plastic container must have a certain strength in order to store the content liquid and maintain a certain external shape and prevent damage, the used plastic container is used. A considerable amount of crushing force is required to crush plastic containers and reduce container volume.

In particular, in the case of a large-bore plastic bottle having a handle, there is a problem that the wall of the bottle body is so thick that it is difficult to crush the handle and that the handle cannot be crushed. In addition, since it is difficult to deform the wall surface under the handle-forming cavity, which forms the handle together with the handle, there is a problem that the volume reduction rate of the upper body cannot be increased.

Therefore, at present, ordinary users discard the plastic bottle with a handle without crushing it. Therefore, the problem that the plastic waste becomes bulky and the transportation efficiency of the waste is not good cannot be solved.

Further, even if the bottle can be easily crushed, a cap must be fitted in the crushed state to prevent the bottle from being restored, and the inside of the bottle must be kept in a reduced pressure state. Sometimes, there is a problem that different materials are mixed.

The present invention has been made to solve the above problems,
First, in a plastic bottle with a handle for storing a liquid content while maintaining a certain strength, a flat waste bottle in which a handle is crushable and a body is flattened,
The flattened waste bottle is rolled up to form a very small volume rounded waste bottle. Third, a rounded waste bottle that can be separately disposed without capping if necessary It is an object of the present invention to provide various types of plastic bottles with handles, with the object of doing so.

[0008]

SUMMARY OF THE INVENTION According to the present invention, in order to crush a handle and increase the volume reduction rate of an upper body, a foldable deformable portion is formed on a handle in a crushable plastic bottle having a handle. The handle is bendable. As an embodiment of the bending deformation portion, a bending portion formed by a middle bulging portion and a concave portion, a concave rib or the like provided on the front side or the back side or both is formed at the middle portion in the longitudinal direction of the handle.
Further, a bending rib is provided at a connecting portion between the upper end of the handle and the body wall surface together with the bending portion.

In order to obtain a flat waste bottle having a flat body, the handle can be bent, and the mouth and the body,
In a crushable plastic bottle having a bottom and a handle, the body includes an upper body formed with a handle forming fossae and a lower body, and a bent rib is provided at a required portion of the lower body. Is disposed, so that the body can be crushed and deformed.

[0010] Further, in order to increase the bending of the handle and to bend the upper body, the body wall of the upper body has a side wall and a curved wall formed by the handle-forming cavity, and the curved wall and the curved wall. A laterally extending bent rib is disposed on a side wall adjacent to the curved wall to enable the upper body to bend.

In order to obtain a very small volume of a rounded waste bottle, a bent rib extending in the lateral direction is provided on the upper body as described above, and a hook is provided on the left side of the bottom wall surface of the bottom. The latching piece having a hook portion is provided at the upper end of the handle, as required, with the latching piece having two hooks at the bottom.

Further, in order to enable the cap and the bottle to be discarded separately, a hook having a hook is protruded on the left side of the bottom wall surface of the bottom, and the hook is engaged with the mouth. The cap should not be fitted and should be separable.

[0013]

Next, a first embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the bottle A1 includes a mouth 1 and a body 2, a bottom 3 and a handle 4 formed by hollowing the body 2.

8a and 8b. Curved wall 14
Is a curved surface connected to the arc edges 18a, b of the front and rear walls 16a, b, and the center of the curved surface is a curved line slightly curved in the vertical direction at a predetermined interval from the axis of the bottle. As shown in FIG. 5, the arc is formed by a curved surface having a transverse cross-sectional shape of an arc extending back and forth around the curve.

A horizontal rib 19 is disposed substantially at the center of the curved wall 14 and extends between the curved wall 14 and the front and rear walls 16a and 16b adjacent to each other with a central portion therebetween. The lower part of the curved wall 14 extends to the lower surface of the handle forming fossae 12, is provided continuously with the bulging peripheral wall 11, and forms a wall surface 20 that covers the right part of the lower trunk 8.

As shown in FIGS. 1, 2 and 3, the handle 4
It extends from the upper end of the shoulder wall 9 and the curved wall 14 so as to be connected to the wall surface 20 of the bulging peripheral wall 11 with the handle forming fossae 12 being opposed to the curved wall 14.
As shown in FIG. 5 throughout, the inner side and the outer side are formed in a crescent cross section with arcs having different diameters.

An intermediate bulging portion 21 which is curved and bulges on both sides of the handle is formed at an intermediate portion in the longitudinal direction of the handle 4, and the intermediate bulging portion is formed at the time of molding the bottle from other portions of the handle. Since it is formed so as to expand, it is thinner. A step is formed between the upper side and the lower side on the front side of the intermediate bulging portion 21, and a crescent-shaped step wall 22 is provided. Inside the upper end of the handle 4, an arc-shaped lower rib 23 is provided along a connection portion with the curved wall 14. A bent portion of the handle is constituted by the crescent-shaped step wall 22 and the lower rib 23 formed on the front side of the intermediate bulging portion 21.

As shown in FIGS. 1 and 2, the lower trunk 8
Is composed of a circular barrel wall 30 that follows the bulging peripheral wall 11 with a step, and a bottom peripheral wall 31 formed to bulge from the barrel wall 30. At the center of the front and rear surfaces of the barrel wall 30, a vertical rib 32 is disposed so as to extend downward from the upper end of the barrel wall 30, and inclined ribs 33a and 33b extend right and left from a position spaced apart from the lower end by a predetermined distance. And extends to an intermediate portion of the bottom peripheral wall 31.

On the right peripheral surface 30b of the barrel wall 30, there is provided an arc-shaped rib 34 connecting the upper ends of the front and rear vertical ribs 32 and having the center line on the right peripheral surface as the lowest point. 32
A horizontal rib 35 is provided in the horizontal direction at a fixed interval from the lower ends of the a and 32b. Left and right peripheral surfaces 3 of barrel wall 30
At 0a and b, wide concave grooves 36 are arranged at equal intervals in the vertical direction with the center of the front and rear surfaces separated.

As shown in FIG. 6, the horizontal ribs 19 and 35, the vertical ribs 32, the inclined ribs 33a and 33b, the lower ribs 23, and the arcuate ribs 34 are concave ribs each having a circular cross section.
This is a bending rib 37 for crushing deformation. When the bottle is crushed and deformed, it does not bend in the longitudinal direction of the rib, but the cross section of the rib is deformed in the transverse direction and the connection portion with the wall surface 3
8 is bent, and the wall surfaces on both sides are easily bent inward or outward around the bending rib 37 as an axis.
When the bending angle increases, plastic deformation occurs beyond the elastic limit at the connecting portion 38 of the bending rib 37 or at the circular arc portion 39, so that the deformed shape can be maintained. Each of the bending ribs 37 is a concave rib, but may be a convex rib depending on the location.

As shown in FIGS. 4 and 7, the bottom 3 is
0 and the bottom peripheral wall 31 of the body 2 formed on the periphery of the bottom wall 40
The bottom wall 40 is located on the parting line and has a deepest recessed bottom surface portion 40a which is deviated leftward from the center of the parting line.
It is formed of a curved surface that is smoothly continued from a to the bottom end wall 41.

On the left side of the bottom wall 40, a hook portion 42 protruding inward at the tip is provided, and a retaining piece 43 extending substantially in the horizontal direction is provided.
Are provided along the parting line. The root portion of the retaining piece 43 is located close to the bottom end wall 41, and the hook portion 42 is located corresponding to the bottom surface portion 40a and is formed so as to protrude inward.

On the bottom wall 40, a ridge 44 is formed along the parting line rightward from the root of the retaining piece 43,
The bottom wall 40 is reinforced. The bottom end wall 41 has a cutout portion 45 at a position facing the parting line back and forth, and a concave portion 46 at a position facing the parting line.

Next, a method of crushing the bottle will be described. When crushing a bottle after use, it is efficient to place the bottle on a desk with the handle on the right side of the bottle and crush it. (When the bottle is placed on a desk, the left and right sides of the bottle axis are up and down, and the front and back are left and right, but use the above-mentioned designation as it is.)

The outline of the crushing method is as follows. First, the body 2 or the mouth 1 is pressed and the middle part of the handle 4 is bent. Next, the upper part of the lower torso part 8 and the lower part thereof are strongly pressed from the right side, and the left and right torso walls of the lower torso part 8 are deformed by the vertical ribs 32 to become flat. With this, the body peripheral wall 10 of the upper body 7 is deformed to be flat. Next, the bottom portion 3 is rotated to obtain a flattened waste bottle. Finally, the flattened waste bottle is entirely bent, and a hooked 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 order of crushing and the details of the operation at that time will be sequentially described with reference to the drawings. First, first, the bottle mouth 1 or the body 2 is pressed, and a portion of the handle 4 on the middle portion front side in the longitudinal direction is pressed. When a bending force is applied to the handle 4, as shown in FIG.
Is bent at the portion below the step wall 22 of the intermediate bulging portion 21 toward the trunk wall. At the same time, the upper body is also pressed and partially deformed to some extent.

Secondly, when the upper part of the barrel wall 30 is pressed from the right (arrow a in FIG. 8), the right side of the bulging peripheral wall 11 and the right peripheral surface 30b of the barrel wall 30 are moved. The bending force acts, and as shown in FIG.
4 is folded so that the right side portion of the bulging peripheral wall 11 is bent downward.

Third, when the lower part of the barrel wall 30 is pressed from the right (arrow b in FIG. 9), as shown in FIG.
The lower part of the right peripheral surface 30b is bent with the horizontal rib 35 as a fold, and the bottom peripheral wall 31 is inclined accordingly. The left peripheral surface 30a and the right peripheral surface 30b of the barrel wall 30 are
The barrel wall 30 is bent about the vertical rib 32 to be flattened, and the vertical rib 32 projects forward and backward accordingly.

The flattening of the barrel wall 30 affects the circumferential wall 10 of the upper barrel 7. Since the front and rear walls 16 are difficult to bend in the transverse direction due to the transverse ribs 19 extending from the curved wall 14, the trunk peripheral wall 10 bends at the connection edges 17a and 17b between the side walls 15b and c and the front and rear walls 16 to be front and rear. Bulge in the direction.

Fourth, next, when the bottom 3 is bent upward as shown by the arrow c in FIG. 10, the bottom 3 is bent with the horizontal rib 35 of the right peripheral surface 30b as a fold, and the bottom peripheral 3 and the right peripheral surface 30b are bent. The right portion of the peripheral wall 31 is a continuous surface, and the bottom wall 40 is further inclined. Thus, the trunk 2 is shown in FIG.
As a result, a flat body portion 2a as shown in FIG. 12 is obtained, and a flat 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. Although the waste bottle can be discarded in this state, the flat waste bottle can be further curved to form a rounded waste bottle.

Fifth, next, the entire bottle is bent by holding the mouth 1 and the bottom 3 and a moment M is applied between the mouth 1 and the bottom 3 (see FIG. 11). The bottom 3 is pressed by the flat body 2a to be slightly flat, and the body peripheral wall 10 is bent around the horizontal rib 19, and the handle 4 is further bent accordingly. The handle 4 has a lower rib 23 and a step wall 2 because the intermediate bulge 21 is thinner.
2, the lower end of the step wall 22 expands the intermediate bulging portion 21 in the width direction to cause plastic deformation, flattening the front and back surfaces of the middle portion of the handle 4, and A pressure is applied to the curved wall 14 of the trunk peripheral wall 10.

Next, when a moment M (see FIG. 13) is further applied, and the mouth 1 and the bottom 3 are rounded, the upper and lower portions of the flat body 2a are further bent, and the bottom wall 40 is bent. It can be curved until it touches the side peripheral surface. In this state, when the hook 42 of the retaining piece 43 provided on the bottom wall 40 is engaged with the inner periphery of the mouth 1, the mouth 1
And the bottom portion 3 can be maintained in the locked state, and as shown in FIG. 14, a waste bottle in which the flat body portion 2a is rounded can be obtained.

When the flat body 2a is crushed, the flat body 2a undergoes plastic deformation and does not recover unless an external force is applied. However, the curvature of the flat body 2a may not reach plastic deformation. Locking the bottom 3 prevents the flattened body 2a that is curved and rounded at the time of disposal from being restored. 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 facing upward and crushed, the upper side (right side) of the bottle is
Crushing is performed efficiently because the pressing force acts as a reaction on the left side, but if the bottle is crushed with both hands, the crushing is performed sequentially from the left and right in accordance with the crushing order described above. It can be crushed by pressing. In that case, first, the torso peripheral wall of the upper torso is pressed from the left and right together with the handle, and the upper torso wall is deformed simultaneously with the bending of the handle. Next, although the lower torso is crushed, the order may be changed, and the lower torso may be pressed and deformed first, and then the handle and the upper torso may be pressed and deformed thereafter.

Next, a second embodiment of the present invention will be described with reference to the drawings. This embodiment is an embodiment in which the shapes of the handle and the trunk, particularly the arrangement positions of the bent portion of the handle and the bent rib of the trunk are changed.

Next, a method of crushing the bottle will be described. First, the outline of the crushing method will be described. Torso 51 is pressed from the left and right to invert the torso wall to reduce the volume, and further crushed to form a flat torso 51a, and then the handle 53 is crushed, and the bottom is crushed. Rotate to make a flat waste bottle. Next, the flattened upper body portion 56 is bent around the horizontal rib 68, and the flat body portion 51a is curved so that the mouth portion 50 and the bottom portion 52 are joined.
By locking the hook 92 of either a or b with the mouth 50 or the hook 74 of the handle 53, a waste bottle in a rolled-up state can be obtained.

Next, regarding the action at the time of crushing the bottle,
This will be described with reference to the drawings. First, when the barrel wall 80 of the lower body portion 57 is pressed from the left and right, the left peripheral surface 80a is
As shown in FIGS. 2 and 23 (b), the left peripheral surface of the bottom peripheral wall 81 is bent around the horizontal rib 83 as an axis. The right peripheral surface 80b of the barrel wall 80 is inverted inward with the horizontal rib 84 and the vertical ribs 85a and 85b as axes, and the right peripheral surface of the bottom peripheral wall 81 is bent with the horizontal rib 86 as an axis.

When the torso peripheral wall 59 of the upper torso 56 is pressed from the left and right, as shown in FIGS.
Are turned around the end edges 66a, b of the front and rear walls 65a, b, and the bulging peripheral wall 60 also has the longitudinal ribs 82a, b and the end edges 66a, 66b.
Invert around the line connecting b.

At this time, the deformation of the left peripheral surface 80a of the lower body 57 acts to facilitate the reverse deformation of the left side of the upper body 56. In addition, when the upper body 56 is reversed first, the lower body 57 acts so as to be easily inverted. Thus, the entire structure is deformed as shown in FIGS.

Next, in the state of FIG.
7 is pressed from the left and right, the barrel wall 80 of the lower trunk 57 is pressed.
Is bent at the left and right central portions, the intermediate portion swells in the front-rear direction, and is flattened across the left and right central surfaces.

Next, when the torso peripheral wall 59 of the upper torso 56 is pressed from the left and right, the front and rear walls 65 are difficult to bend due to the lateral ribs 68 extending from the curved wall 63.
Is bent at the connection edges 66a, b between the inclined walls 64b, c and the front and rear walls 65a, b and swells in the front-rear direction, and is affected by the bending and swelling of the lower trunk 57 as going downward. The bulge of the body 57 is curvedly continuous. 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, the bottle mouth 50 or the bulging peripheral wall 60
When a bending force is applied to the handle 53, the handle 53 is bent at the concave portion 72 of the intermediate bulging portion 70 or at the lower end of the lower step wall 71b as shown in FIG.

At this time, the right peripheral surface of the bulging peripheral wall 60 is difficult to deform due to the wall surface 69, but is pulled upward by the bending of the handle 53, and the bulging peripheral wall 60 of the upper body portion 56 is According to the deformation of the peripheral wall 59 and the left peripheral surface 80a of the barrel wall 80, the peripheral wall 59 is deformed until it becomes substantially semicircular. Thus, the torso 51 has the upper torso 56 halved and the lower torso 5
7 is deformed into a flat body portion 51a that has become flat.

The mouth portion 50 and the shoulder wall 58 around the mouth portion 50 are thick and maintain their original shape without being deformed. next,
When the bottom 52 is rotated counterclockwise, the flat body 51a is rotated.
By changing the angle between the bottom and the bottom 52, a flattened waste bottle deformed to the state shown in FIG. 24 can be obtained.

Next, when a bending moment M is applied between the mouth portion 50 and the bottom portion 52 from the state shown in FIG. 24, the front and rear walls 65a and 65b and the curved wall 63 are bent around the horizontal rib 68 as an axis. The torso peripheral wall 59 of the upper torso portion 56 is curved, and when a bending moment M is applied, the flat torso portion 51a is bent and can be curved until the peripheral surface of the mouth portion 50 contacts the bottom wall 90.

In this state, the hook 92 of the hook 93b provided on the bottom wall 90 is engaged with the hook 74 of the handle 53, or the hook 92 of the hook 93a is attached to the inner periphery of the mouth 50. When engaged, the handle 53 and the bottom 52, and the mouth 50
25 can be maintained in the locked state.
As shown in (a) and (b), the waste bottle is deformed into a state in which the flat body portion 51a is rounded.

In crushing, the flat torso portion 51a undergoes plastic deformation and does not recover unless an external force is applied. However, the curvature of the flat torso portion 51a may not reach plastic deformation. By locking the 52, the flat trunk portion 51a that is curved and rounded at the time of disposal is prevented from restoring. Thus, the waste bottle can be a waste bottle rounded to a very small volume.

Next, the effect of providing the two retaining pieces 93a, b on the bottom wall will be described. When the retaining piece 93a is engaged with the inner periphery of the mouth 50, the cap is covered. Although they cannot be fitted, the positions of the retaining piece 93a and the mouth 50 can be easily confirmed, so that the engagement can be facilitated. Further, when the retaining piece 93b is engaged with the locking piece 73 of the handle 53, the cap can be fitted on the waste bottle and disposed. When the bottle and the cap are made of different resin materials and need to be discarded separately, it is possible to arbitrarily select which of the retaining pieces 93a and 93b is used.

Next, a third embodiment will be described with reference to the drawings. In this embodiment, the shape of the lower trunk is changed, and the arrangement of the bending ribs is changed. FIG.
