Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid container made of synthetic resin for enclosing drinking water, juice, milk and other liquids.

[0002]

2. Description of the Related Art At present, garbage discharged from homes is said to be 800 g per day. In addition, the number of households and the amount of garbage discharged from factories and offices around the world are astronomical figures, and this garbage disposal is now a major social issue.
Recently, however, synthetic resin containers called “bottles” have become very popular, and the demand for these containers has greatly increased. The volume must be reduced to 15% or less of the above-mentioned garbage amount. The Environment Agency's "white paper" reports. For this reason, these synthetic resin containers which are difficult to incinerate are considered to be reused and recycled, and so-called “garbage” and “synthetic resin containers” have been widely distributed and collected. The problem is that when collecting empty containers, this kind of synthetic resin container has a large volume, so it is said that transporting it by car is equivalent to carrying air. The trader
In most cases, compensation is calculated based on the weight carried in, and the current situation is that there is no active collection work by traders.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a container filled with a liquid which can sufficiently cope with violent vibration when collecting an empty synthetic resin container. Substantially reducing the volume of the container has dramatically increased the amount of transportation during recovery.

[0004]

SUMMARY OF THE INVENTION A feature of the present invention is that the container body is shaped such that its volume is substantially reduced by applying a load in the vertical and / or torsional direction. That is, means for holding the reduced shape is provided on the container body.

A feature of the present invention is that the peripheral wall of the container body is formed as a thin, serpentine-shaped portion having a relatively hard thickness, and the serpentine-shaped portion is formed substantially in the central portion. One of the features is that the diameter is gradually reduced from the diameter in the vertical direction.

A feature of the present invention is that the container body is formed in such a shape that its volume is substantially reduced, and the container main body is formed in a relatively hard and thin vertical star shape.

A feature of the present invention is that the container body is formed in such a shape that its volume is substantially reduced, and the container body is formed to have a relatively hard wall thickness and a thin continuous or discontinuous number of inclined grooves. It was done.

A feature of the present invention is that the container body is formed in such a shape that its volume is substantially reduced, and the container body is formed into a relatively hard and thin concave portion.

A feature of the present invention resides in that a belt is suspended between the mouth of the container body and the cap body in order to maintain a shape in which the volume is substantially reduced.

A feature of the present invention is that the opening can be fitted into the container body by pressing the opening as a means for maintaining the shape such that the volume is substantially reduced. That is what we did.

A feature of the present invention is that, as a means for maintaining a shape for substantially reducing the volume of the container body, the height of the container body is shorter than the height of the container body, and the end has a hook portion capable of engaging with the bottom of the container body. That is, a plurality of legs are suspended from the container body.

A feature of the present invention is that, as means for maintaining a shape for substantially reducing the volume of the container main body, the height is shorter than the height of the container main body, and the upper end has a hook portion capable of engaging with the peripheral wall of the container main body. Is provided below the container body.

[0013]

Embodiment 1 In FIG. 1, (1) is a liquid container body made of a flexible synthetic resin material having a reduced diameter and a relatively hard mouth (2) at its upper end. is there. Reference numeral (3) denotes a cap body (3) covered with the mouth (2).
The peripheral wall (4) of the container body (1) is formed in a bellows-like shape (5) in the vertical direction from the bottom of the mouth (2) to the bottom surface. The container body (1) is filled with a liquid such as mineral water by a usual device and ordinary means, covered with a cap body (3), and shipped around the market. Even if there is, the container body (1) has a bellows-like shape (5) on its peripheral wall (4), so that the bellows portion acts as a guard.

After the liquid has been drunk up, the container body (1) is crushed in the direction of its center. In this case, since the container body (1) is flexible and flexible and the peripheral wall (4) has a bellows shape (5), this operation is extremely easy. Also, this crushing operation is insufficient by hand. In this case, the container body (1) may be placed on the ground or the like and crushed by the foot. The volume of the crushed container body (1) can be extremely small even as it is.

[0015] In fact, the inventor of the present application has proposed that the content of a commercially available green tea bottle is 500 ml (height 21 cm x diameter 7c).
mφ), the surrounding wall (4) was made bellows-like (5) as in the present invention, and various crushing operations were performed. The results were all less than 1/4 of the height of the container body (1), that is, 5 cm or less. And could be. It is just a comparison between the mouth (2) and the lower part. The hardened container body (1) is tapered (1).
It is equal to about twice the height (L) of 1). It is relatively easy to carry a large amount of the crushed volume at a time less than one-fourth of that of the entire container body (1) for recycling, etc. Although not required, the problem is whether the container body (1) can remain collapsed until this transport.
I also experimented with various materials that are commercially available, and the results are those that keep the crushed state for a long time, those that keep it for several hours, or those that are only a few minutes for a very short time However, there were various things that tried to return to the original shape.

Therefore, as shown in FIG. 9, the container body (1)
If the cap (3) is put on the mouth (2) again after crushing, the air does not enter the container body (1),
Therefore, it is possible to maintain the crushed state. However, usually, after removing the cap body (3) from the container body (1), the cap body (3) is not discarded or lost and does not end. Thus, the cap body (3) cannot be covered after the container body (1) is crushed.

Therefore, in the present invention, the cap body (3) is devised so as to be always connected to the container body (1). That is, FIG.
Reference numeral 0 denotes a belt (6), which is made of a flexible and flexible thin plate-like resin and has through holes (7) on both sides thereof.
(8). On the other hand, a dovetail groove (9) is formed on the outer peripheral surface of the cap body (3), one through hole (7) of the belt (6) is formed in the dovetail groove (9), and the other through hole (8) is a container. The end portion of the screw portion (10) formed in the mouth portion (2) of the main body (1) is fitted. As a result, the cap body (3) is always with the container body (1), and there is no fear of loss or the like, so that the cap body (3) is placed at the mouth of the crushed container body (1).
By covering the container again, the container body (1) can be kept in a collapsed state. In addition, the height of the container body (1) which has been crushed earlier is about 2 times the height of the tapered portion (5).
Times (L). In the present invention, the height, that is, the height of the crushed container body (1) is further reduced. That is, as shown in FIG. 11, the tapered part (11) and the mouth part (2) of the container body (1) in this embodiment and the cap body (3) which is loosely fitted if necessary are also provided in the container body (1). ) When crushed,
This is so-called inverted so that it can be fitted into the container body (1). As a result, the height of the crushed container body (1) does not actually add to the height of the tapered portion (11) and the cap, but reaches the same height (L1) as shown in FIG. The volume was reduced and the volume was made very small.

[0018]

Embodiment 2 As means for substantially reducing the volume of the container body (1), means for crushing the container body (1) from the width direction other than crushing the container body (1) from the height direction may be considered. That is, FIG.
As shown in FIG. 3, vertical irregularities (12) are formed at regular intervals on the outside of the container body (1) to form a star-shaped cross section (13) as shown in FIG. Further, as another example of the means for crushing the container body (1) from the width direction, a plurality of inclined grooves (14) as shown in FIGS. 4 and 5 may be formed. In other words, the container body (1) shown in FIGS.
When the container body (1) itself was squeezed in the same manner as when squeezed to remove moisture from the laundry, the container could be substantially reduced to one third or less.

In order to keep the shape of the crushed container body (1) as it is, the cap body (3) may be fitted again after crushing as described above, but a large number of container bodies (1) are crushed and transported. To do this, a large number of containers can be transported at the same time by arranging the crushed container bodies (1) horizontally in such a manner that the upper and lower portions are sequentially reversed as shown in FIG.

[0020]

Embodiment 3 As means for crushing the container body (1), a synergistic means of crushing from the height direction and crushing from the width direction may be considered. That is, as shown in FIG. 7, a large number of recesses (15) such as diagonal outer peripheral walls of the container body (1).
8, or an oblique groove (1) which is relatively horizontal and continuous to the outer peripheral wall of the container body (1) as shown in FIG.
6). As a matter of course, in FIG. 8, the continuous oblique groove (16) may be discontinuous instead of continuous. When the container body (1) is crushed after drinking the liquid, if the container body (1) is pressed from the height direction, the container body (1) is rotated simultaneously with the load from the vertical direction. Under the directional load, the container body can be easily crushed by the synergistic action of these.

[0021]

Embodiment 4 Various other means are conceivable as means for keeping the crushed container body (1) as it is. For example, in FIGS. 12 and 13, (17) is a cover fitted to the lower portion of the container body (1). This cover body (17) is sent with substantially the same material as the container body (1), attached to the container body (1) filled with liquid and sold at the same time, the upper side is opened, and the open part protrudes inward. It has a bowl shape with a hook shape (18). After the liquid in the container body (1) is swallowed up as described above, when the container body (1) is pressed in the height direction, the container body (1) is fitted into the cover body (17). You will be kept in a crushed state. The example shown in FIG. 13 shows an example in which the peripheral wall (4) has a bellows shape (5). In this case, the bellows shape is the uppermost step of the bellows shape (5), that is, the bellows shape just below the tapered portion (11). (5) The ridge (19) and the hook (18) of the cover body (17) are engaged. Therefore,
It is important that the height or depth of the cover body (17) is the same as the height when the container body (1) is crushed to the maximum.

As shown in FIG. 12, the projecting ridge (19) of the container body (1) preferably has a projecting ridge (19) having a larger diameter than other bellows-like projecting portions. In this case, as shown in FIG. 14, if the diameter of the intermediate portion (20) of the container body (1) is gradually reduced from the diameter (21) (22) in the vertical direction, the cover (17) When the container body (1) is pushed into the container body, the thickness of the container body (1) is substantially equalized in the horizontal direction, and the work is very easy. In addition, cover body (1
7) does not need to be cylindrical, and may have a shape with a gap (23) on the side as shown in FIG.

[0023]

Fifth Embodiment The cover body (15) is not limited to the one fitted to the lower part of the container body (1) as described above, but has a shape as shown in FIGS. A holder (24) made of a similar material may be used. That is, the holder (24) has a disk shape having a hole (25) in the center of which the mouth (2) of the container body (1) can be fitted, and has a plurality of legs (26) from the outside downward. . The leg (26) can abut against the peripheral wall of the container body (1), and at the end thereof, there is a hook (27) that matches the container body (1). This holder (2
4) is commercially available together with the container body (1). When the liquid in the container body (1) is drunk up and the container body (1) is crushed, the hook of the holder (24) is hooked. Part (2
7) is engaged with the bottom surface of the container body (1), and can maintain its crushed state.

[0024]

[Effect] In general, the effect of the present invention is that the volume of the container body after drinking can be substantially reduced, so that the space for the waste storage area can be reduced and a large amount of used containers can be transported at one time. This has spurred the recycling. Further, a means for keeping the reduced volume state at the time of transportation, that is, until the time of waste collection is provided to prevent the reduced container body from returning to the original state.
