Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a plastic bottle that can be easily crushed.
[0002]
[Prior art]
In recent years, disposal of plastic waste has become a major problem, and recycling of used plastic containers has also been implemented.
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]
[Problems to be solved by the invention]
However, plastic containers must have a certain strength in order to store the liquid contents and maintain a certain external shape so as not to be damaged. In order to decrease, a considerable crushing force is required.
[0004]
In particular, a large-bore plastic bottle having a handle has a problem that the wall of the bottle body is thick and difficult to crush, and the handle cannot be crushed.
In addition, since it is difficult to deform the wall surface under the handle forming pit that forms the handle together with the handle, there is a problem that the volume reduction rate of the upper trunk cannot be increased.
[0005]
Therefore, the general user currently discards the plastic bottle with the handle without crushing it.
Therefore, the problem that the plastic waste becomes bulky and the waste transportation efficiency is not good cannot be solved.
[0006]
Also, even if the bottle can be easily crushed, in order to prevent the bottle from being restored, the cap must be fitted in the crushed state and the inside of the bottle must be kept in a reduced pressure state. There was also a problem of material mixing.
[0007]
In order to solve the above problems, the present invention is directed to a plastic bottle with a handle that maintains a certain strength and accommodates a content liquid. First, a flat disposal in which the handle can be crushed and the body is flattened. Secondly, the flattened waste bottle is rounded to a very small capacity rounded waste bottle, and thirdly, it can be discarded separately without a cap if necessary. It is an object of the present invention to provide various plastic bottles with handles for the purpose of making a rounded waste bottle.

The curved wall 14 is a curved surface connected to the circular arc edges 18a, b of the front and rear walls 16a, b, and the center of the curved surface is a curve slightly curved in the vertical direction at a predetermined interval from the axis of the bottle. As shown in FIG. 5, it is formed of a curved surface having an arc extending in the front-rear direction around the curve and having a cross-sectional shape.
[0017]
A lateral rib 19 is disposed substantially in the middle of the curved wall 14 and extends between the curved wall 14 and the adjacent front and rear walls 16a and 16b with a central portion therebetween.
The lower side of the curved wall 14 extends to the lower surface of the handle forming cavity 12, is connected to the bulging peripheral wall 11, and is a wall surface 20 that covers the right side portion of the lower trunk 8.
[0018]
As shown in FIGS. 1, 2, and 3, the handle 4 faces the curved wall 14, separates the handle forming pit 12, and the wall surface 20 around the bulging peripheral wall 11 from the upper end of the shoulder wall 9 and the curved wall 14. As shown in FIG. 5 as a whole, the cross section is formed in a cross-curved moon shape in which the inner side and the outer side are arcs having different diameters.
[0019]
An intermediate bulging portion 21 that is curved and bulges on both sides of the handle 4 is formed in the middle portion in the longitudinal direction of the handle 4, and the intermediate bulging portion is shaped so as to swell more than other portions of the handle at the time of bottle molding. So it is thinner.
On the front side of the intermediate bulging portion 21, a step is formed between the upper side and the lower side, and a crescent-shaped step wall 22 is provided.
On the inner side of the upper end of the handle 4, an arc-shaped lower rib 23 is disposed along the connecting portion with the curved wall 14.
The crescent-shaped step wall 22 and the lower rib 23 formed on the front side of the intermediate bulging portion 21 constitute a bent deformation portion of the handle.
[0020]
As shown in FIGS. 1 and 2, the lower body 8 includes a circular barrel wall 30 that continues to the bulging circumferential wall 11 with a step, and a bottom circumferential wall 31 formed to bulge from the barrel wall 30. It is made up of.

On the left and right peripheral surfaces 30a and 30b of the barrel tube wall 30, wide concave grooves 36 are arranged at equal intervals in the vertical direction with the center portion of the front and rear surfaces therebetween.
[0022]
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 arc-shaped ribs 34 are all concave ribs having an arc-shaped cross section. It is a bending rib 37.
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 connecting portion 38 with the wall surface is bent. It can be easily bent. When the bending angle is increased, plastic deformation occurs beyond the elastic limit at the connecting portion 38 of the bending rib 37 or the 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 arrangement location.
[0023]
As shown in FIGS. 4 and 7, the bottom portion 3 includes a bottom wall 40 and a bottom end wall 41 that is formed on the periphery of the bottom wall 40 and continues to the bottom peripheral wall 31 of the trunk portion 2.

On the bottom wall 40, ridges 44 are formed along the parting line to the right from the base portion of the hanging piece 43 to reinforce the bottom wall 40.
The bottom end wall 41 is formed with a notch 45 at a position facing the parting line in the front-rear direction, and a recess 46 is formed at a position facing the parting line.
[0026]
Next, the crushing method of a bottle is demonstrated.
When crushing a bottle after use, it is efficient to place the bottle on the desk with the handle on the right side of the bottle and crush it. (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.
[0027]
The outline of the crushing method will be described. First, the body part 2 or the mouth part 1 is pressed and the middle part of the handle 4 is bent.
Next, the upper part of the lower body part 8 and then the lower part are pressed strongly from the right side, and the left and right body walls of the lower body part 8 are deformed with the vertical ribs 32 as a boundary to make them flat.
Accordingly, the body peripheral wall 10 of the upper body 7 is deformed to be flat.
Subsequently, the bottom 3 can be rotated to obtain a flattened waste bottle.
Finally, the entire flattened waste bottle is curved, and a hanging waste piece 43 having a flange 42 provided on the bottom 3 is engaged with the upper edge of the mouth 1 to obtain a rounded waste bottle. .
[0028]
Next, details of the crushing order and the action at that time will be described sequentially with reference to the drawings.
First, the bottle mouth part 1 or the body part 2 is pressed first, and the part on 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, as shown in FIG. 8, the handle 4 is bent at the portion of the lower rib 23 and bent toward the trunk wall side below the step wall 22 of the intermediate bulging portion 21. . At the same time, the upper trunk is also pressed and partially deformed to some extent.
[0029]
Second, when the upper portion of the barrel wall 30 is pressed from the right (arrow a in FIG. 8), a bending force is applied between the right portion of the bulging peripheral wall 11 and the right peripheral surface 30b of the barrel wall 30. As shown in FIG. 9, the right peripheral surface 30b is bent with the arc-shaped rib 34 as a fold, and the right portion of the bulging peripheral wall 11 is bent downward.
[0030]
Third, when the lower portion of the barrel wall 30 is pressed from the right (arrow b in FIG. 9), the lower portion of the right peripheral surface 30b is bent with the lateral rib 35 as the fold as shown in FIG. The bottom peripheral wall 31 is inclined.
And the left side peripheral surface 30a and the right side peripheral surface 30b of the trunk cylinder wall 30 are bent with the vertical rib 32 as an axis so that the trunk cylinder wall 30 is flattened, and the vertical rib 32 projects forward and backward accordingly. .
[0031]
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 b between the side walls 15 b and c and the front and rear walls 16. Bulge in the direction.
[0032]
Fourth, when the bottom portion 3 is bent upward as indicated by an arrow c in FIG. 10, the bottom portion 3 is bent with the lateral rib 35 of the right peripheral surface 30b as a fold, and the right peripheral surface 30b and the bottom peripheral wall 31 are bent. The right part becomes a continuous surface and the bottom wall 40 is further inclined.
Thus, the body portion 2 becomes a flat body portion 2a as shown in FIGS. 11 and 12, and a flattened waste bottle can be obtained.
At that time, plastic deformation is caused in other portions as well as the bent and bulged portions, and the flat state is maintained.
Although it can be discarded in this state, the flat waste bottle can be further bent into a rounded waste bottle.
[0033]
Fifth, holding the mouth part 1 and the bottom part 3 and then bending the entire bottle and applying a moment M between the mouth part 1 and the bottom part 3 (see FIG. 11), as shown in FIG. Is slightly flattened by being pressed by the flat barrel portion 2a, and the barrel peripheral wall 10 is bent with the horizontal rib 19 as an axis, and the handle 4 is further bent accordingly.
The handle 4 is further bent at the lower rib 23 and the step wall 22 because the intermediate bulge 21 is thinner, and the lower end of the step wall 22 expands the intermediate bulge 21 in the width direction and is plastic. Deformation is caused, the front and back surfaces of the middle portion of the handle 4 are flattened, and the back surface of the stepped wall 22 is brought into contact with the curved wall 14 of the trunk peripheral wall 10.
[0034]
Next, when the moment M (see FIG. 13) 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 becomes the mouth portion 1 side peripheral surface. It can be bent until it touches.
In that state, when the collar portion 42 of the retaining piece 43 provided on the bottom wall 40 is engaged with the inner periphery of the mouth portion 1, the mouth portion 1 and the bottom portion 3 can be maintained in a locked state, as shown in FIG. As shown, a waste bottle in a state where the flat barrel portion 2a is rolled up can be obtained.
[0035]
In flat crushing, the flat barrel portion 2a is plastically deformed and is not restored unless an external force is applied, but 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 can be a waste bottle rounded to a very small capacity.
[0036]
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, when the bottle is held and crushed by both hands, it can be crushed by sequentially pressing from the left and right according to the crushing order.
At that time, first, the upper peripheral wall of the upper body part is pressed from the left and right together with the handle, and the upper body wall is deformed simultaneously with the bending of the handle.
Next, the lower body portion is crushed, but the order may be changed, and the lower body portion may be first pressed and deformed, and the handle and the upper body portion may be subsequently deformed by pressure.
[0037]
Next, a second embodiment of the present invention will be described with reference to the drawings.
The present embodiment is an embodiment in which the shape of the handle and the body part, particularly the arrangement position of the bending deformation part of the handle and the bending rib of the body part is changed.

In order to form the locking piece 73, the facing portion of the shoulder wall 58 is a flat portion 75.
[0043]
As in the first embodiment, the lower body 57 includes a circular body wall 80 following the bulging wall 60 and a bottom wall 81 formed so as to bulge from the body wall 80. It has become.
Two vertical ribs 82 a and b are disposed on the left peripheral surface 80 a of the trunk wall 80, and the lower end thereof extends to the bottom peripheral wall 81, and the arc-shaped horizontal rib 83 connecting both lower ends is the bottom peripheral wall 81. It is arranged.
[0044]
A lateral rib 84 is provided on the right peripheral surface 80b of the barrel wall 80 so as to be connected to the bulging peripheral wall 60, and vertical ribs 85a and 85b are suspended from both ends thereof.

The bottom end wall 91 is formed with a notch 94 at a position facing the parting line in the front-rear direction, and a recess 95 is formed at a position facing the parting line.
[0047]
Next, the crushing method of a bottle is demonstrated.
First, an outline of the crushing method will be described. The body 51 is pressed from the left and right to invert the body wall to reduce the volume, and further crushed to a flat body 51a, and then the handle 53 is crushed to Turn to a flattened waste bottle.
Next, the flattened upper body portion 56 is bent with the horizontal rib 68 as an axis, the flat body portion 51a is bent so that the mouth portion 50 and the bottom portion 52 are joined, and finally the hanging piece 93a of the bottom wall 90 is joined. , B is engaged with the collar part 74 of the mouth part 50 or the handle 53 to obtain a rounded waste bottle.
[0048]
Next, the action at the time of crushing the bottle will be described with reference to the drawings.
First, when the body cylinder wall 80 of the lower body part 57 is pressed from the left and right, the left peripheral surface 80a is inverted around the longitudinal ribs 82a and 82b as shown in FIGS. The left peripheral surface is bent with 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 b as axes, and the right peripheral surface of the bottom peripheral wall 81 is bent with the horizontal rib 86 as an axis.
[0049]
When the body peripheral wall 59 of the upper body 56 is pressed from the left and right, as shown in FIGS. 22 and 23 (a), the side wall 62 is inverted with the edges 66a and 66b of the front and rear walls 65a and 65b as axes. 60 is also reversed with the line connecting the longitudinal ribs 82a, b and the end edges 66a, b as axes.
[0050]
At that time, the deformation of the left peripheral surface 80a of the lower body part 57 acts to facilitate the reverse deformation of the left side surface of the upper body part 56.
Further, when the upper trunk portion 56 is reversed first, the lower trunk portion 57 acts to facilitate the reverse deformation.
In this way, it is deformed as a whole as shown in FIGS.
[0051]
Next, in the state of FIG. 22, when the lower trunk portion 57 is pressed from the left and right, the barrel wall 80 of the lower trunk portion 57 is bent at the left and right central portions, and the middle portion bulges in the front and rear direction. It is flattened across the surface.
[0052]
Next, when the body peripheral wall 59 of the upper body part 56 is pressed from the left and right, the front and rear walls 65 are difficult to be bent by the lateral ribs 68 extending from the curved wall 63, and therefore the body peripheral wall 59 includes the inclined walls 64b and c and the front and rear walls 65a. , B are bent at the connecting edges 66a, b and bulge in the front-rear direction, and are affected by the bending and bulging of the lower body 57 as it goes downward, and the bulging part of the lower body 57 is curved. Will be continuous.
At that time, plastic deformation is caused in other portions as well as the bent and bulged portions, and the flat state is maintained.
[0053]
Next, when the bottle mouth portion 50 or the bulging peripheral wall 60 is held and a bending force is applied to the handle 53, the handle 53 has a recess 72 or a lower step on the intermediate bulging portion 70 as shown in FIG. It is bent at the lower end of the wall 71b.
[0054]
At that time, the right peripheral surface of the bulging peripheral wall 60 is difficult to be deformed by the wall surface 69, but is pulled upward by the bending of the handle 53, and the bulging peripheral wall 60 of the upper trunk portion 56 is connected to the trunk peripheral wall 59. In accordance with the deformation of the left peripheral surface 80a of the barrel wall 80, it is deformed until it becomes substantially semicircular.
Thus, the body 51 is deformed into a flat body 51a in which the upper body 56 is halved and the lower body 57 is flattened.
[0055]
The mouth portion 50 and the surrounding shoulder wall 58 are thick and maintain their original shape without being deformed.
Next, when the bottom portion 52 is rotated counterclockwise, the angle formed by the flat barrel portion 51a and the bottom portion 52 is changed, and the flattened waste bottle is deformed into the state shown in FIG.
[0056]
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 with the horizontal rib 68 as an axis, and the upper trunk portion The 56 peripheral wall 59 is curved, and further, when the bending moment M is applied, the flat body part 51 a can be bent and curved until the mouth part 50 side peripheral surface comes into contact with the bottom wall 90.
[0057]
In that state, the hook 92 of the retaining piece 93b provided on the bottom wall 90 is engaged with the hook 74 of the handle 53, or the hook 92 of the hanging piece 93a is engaged with the inner periphery of the mouth 50. Then, the handle 53 and the bottom portion 52, and the mouth portion 50 and the bottom portion 52 can be maintained in a locked state. As shown in FIGS. 25 (a) and 25 (b), the waste bottle has a flat body portion 51a. It is transformed into a rounded state.
[0058]
At the time of crushing, the flat barrel portion 51a is plastically deformed and is not restored unless an external force is applied. However, since the curvature of the flat barrel portion 51a may not lead to plastic deformation, the mouth portion 50 and the bottom portion 52 are engaged. By stopping, the flat trunk portion 51a curved and rounded at the time of disposal is prevented from being restored.
Thus, the waste bottle can be a waste bottle rounded to a very small capacity.
[0059]
Next, the effect of providing two hanging pieces 93a and b on the bottom wall will be described. When the hanging piece 93a is engaged with the inner periphery of the mouth portion 50, the cap is fitted. Although it is impossible to confirm the position of the retaining piece 93a and the mouth portion 50, the engagement can be easily performed.
Further, when the hanging piece 93b is engaged with the locking piece 73 of the handle 53, the cap can be fitted into the waste bottle and discarded.
When the material resin of the bottle and the cap is different and needs to be discarded separately, it is possible to arbitrarily select which of the hanging pieces 93a and b is used.
[0060]
Next, a third embodiment will be described with reference to the drawings.
In the present embodiment, the shape of the lower body portion is changed, and the arrangement of the bending ribs is changed.
As shown in FIGS. 26 and 27, the bottle A3 includes a mouth part 101 and a body part 102, and a bottom part 103 and a handle 104 formed so as to cut out the body part 102.

Next, if necessary, the upper body 107 can be bent to bend the flat body 102a to obtain a rounded waste bottle.
[0071]
Next, the action at the time of crushing the bottle will be described with reference to the drawings.
First, when the lower body 108 of the bottle A3 is pressed from the left and right, as shown in FIGS. 33 and 34 (b), the left side wall 130 and the inclined walls 132a and b are connected to the front and rear walls 134 and the inclined end edge 121. The rib 135 is inverted and deformed around the axis.
As the side wall 130 is reversed, the bottom peripheral wall 113 is also curved.
[0072]
The right side of the lower body 108 is inverted and deformed with the connection edge 121 between the inclined wall 133 and the front and rear walls 134 as an axis. At this time, the side wall 131 has the upper lateral rib 138 and the lower lateral rib 137 as axes.
