Conventionally, most containers for drinking water and the like are made of glass, and the use of a plastic bottle 41 made of synthetic resin as shown in FIG. 9 has been promoted in order to reduce the weight from the viewpoint of transportation and storage. ing. As described above, the plastic bottle 41 made of synthetic resin has an advantage that the weight of the container itself is much lighter than that of the glass container and the cost can be reduced.

[0003]

Although the plastic bottle 41 after drinking the content has been recently collected along with the recycling movement, the amount of collection is currently insignificant, and most of them are collected. The PET bottle 41 is disposed of as household waste. The current PET bottle 41 is not easily crushed by hand, and is discarded as it is in the shape shown in FIG. Therefore, there is a problem that the dust bag becomes bulky. Also, this kind of plastic bottle 4
No. 1 is landfilled as non-burnable garbage because it produces toxic gas when incinerated. But plastic bottle 4
In the case of filling 1 as well, there is a problem in that the filled volume immediately becomes full because it is filled with the shape as it is.

Further, after use, the PET bottle 41 is thrown away without the cap 42, and water is accumulated in the PET bottle 41 due to rain or the like, and the PET bottle 4
There was also a problem that bow hula and the like sprung up in 1 and it was very unsanitary and environmentally unfriendly.

The present invention has been provided in view of the above-mentioned points. By compressing a container after use to reduce its volume, the volume at the time of discarding as garbage is reduced, and landfill is performed. In this case as well, the purpose is to provide a container whose landfill site is less than a fraction of the conventional one.

[0006]

Therefore, in the container according to claim 1 of the present invention, a bellows part 4 which is vertically compressible is provided on a body part 3 of a cylindrical container body 1 made of synthetic resin, The bellows portion 4 is characterized by being formed over substantially the entire length of the container body 1 in the vertical direction.

In the container according to claim 2, the container body 1
It is characterized in that members 10 and 16 for holding the compressed state of the container body 1 are provided by being hooked and locked from above and below.

Further, in the container according to claim 3, the holding members 22 and 21 are integrally formed on the upper and lower portions of the container body 1, and the upper and lower holding members 22 and 21 are hooked and locked, whereby the container body is It is characterized in that the compressed state 1 is maintained.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1A shows a front view of a PET bottle-shaped container body 1, and a cap 2 is attached to the upper part thereof. For example, juice, soft drinks, sports drinks, and other drinking water can be placed in the container body 1. The material is a synthetic resin that is normally used for PET bottles other than glass, which are currently on the market. It is formed by. A bellows portion 4 is formed on the body portion 3 except the upper and lower portions of the container body 1.

That is, the bellows portion 4 is formed over substantially the entire length of the container body 1 excluding the upper and lower portions,
The bellows portion 4 allows the container body 1 to be vertically compressed. Usually, the bellows portion 4 of the container body 1 is extended so that a prescribed amount of drinking water or the like can be contained therein. FIG.
(A) is this state. When all the drinking water in the container body 1 has been drunk, it is pressed down from above the container body 1 with a hand or the like, as shown in FIG.
Are compressed, and the height of the container body 1 itself becomes low. That is, by compressing the container body 1, it is possible to reduce the height to a fraction of the height before compression.

As a result, the compressed container body 1 becomes less bulky and maintains its compressed state. Therefore, the container body 1 is not bulky and can be disposed in the garbage bag many times more than when the container body 1 is not compressed. Therefore, the number of garbage bags is reduced, and the collection work by the garbage truck becomes easier. Further, even when it is landfilled as non-burnable dust, the container body 1 remains compressed, so the space for landfill can be made smaller than that when it is not compressed, and if the landfill volume is the same, it is not compressed. The container body 1 can be filled up in many times as compared with the above. Therefore, if the number of container bodies 1 is the same, the landfill can be reduced to a fraction or less. Further, when the container body 1 is compressed, the amount of rainwater entering the container body 1 is reduced, and the rate of occurrence of bow hula and the like is reduced as compared with the conventional case.

As described above, the container body 1 uses a synthetic resin as a material, the bottom portion of the container body 1 is made hard, and the portion above the bottom portion is not so soft and is made to some extent hard synthetic resin. I am trying. In other words, when the bottom of the container body 1 is made thicker and harder, and the parts other than the bottom are made thinner to enable compression of the bellows part 4, and when the contents are put in the container body 1. In addition, the container body 1 itself is prevented from being deformed or falling.

(Second Embodiment) FIGS. 2 to 6 show a second embodiment of the present invention. In the case of FIG. 1, even if the container body 1 is compressed, since the synthetic resin is used as the material of the container body 1, the bellows part 4 returns to some extent, and the volume becomes a little larger than the completely compressed state. . Therefore, it was decided to keep the container body 1 in a completely compressed state.
It is an example shown in FIGS.

That is, the pressing member 10 for pressing the container body 1 from above and the receiving member 16 located on the lower surface side of the container body 1 hold the compressed state of the container body 1. 10 and the receiving member 16 are configured as accessories of the container body 1. Holding member 10
Is made of, for example, cloth or elastic plastic, and is formed in a substantially cross shape as shown in FIG. The strip-shaped tongues 12 are integrally formed from the four sides of the central ring portion 11, and locking holes 13 are formed at the circular tips of the tongues 12, respectively.

On the other hand, as shown in FIGS. 3 and 6, the receiving member 16 is made of plastic or the like and has a substantially cross shape. A protrusion 17 is integrally provided at the center of the receiving member 16, the tip side of each piece 18 is bent upward, and an elastic hook piece 19 is integrally formed at the tip. As in the case of FIG. 1, a hole 6 is recessed in the lower surface of the container body 1 having the bellows portion 4.

The used container body 1 is compressed in the same manner as described above, and the receiving member 16 is inserted into the hole 6 of the container body 1 as shown in FIG.
The container body 1 so that the projection 17 of
Put on. Then, the ring portion 11 of the pressing member 10 is inserted from above the container body 1 (see FIG. 5), and the hook piece 19 of the receiving member 16 is engaged with the locking hole 13 of each pressing member 10 as shown in FIG. Stop. Thereby, the container body 1 can be maintained in a compressed state.

Here, the pressing member 10 and the receiving member 16 are formed in a cross shape, and the protrusion 17 and the hole 6 are formed so that the pressing member 10 and the receiving member 16 are formed.
Although the tongue piece 12 of the pressing member 10 and the piece 18 of the receiving member 16 are each only two (linear), the compressed state of the container body 1 is prevented by the projection 17 and the hole 6. Can be securely held. Further, when four tongue pieces 12 and pieces 18 are formed as shown in the drawing, the hole 6 of the container body 1 and the projection 17 of the receiving member 16 may not be formed. By fitting the holes 6 and the protrusions 17, the compressed state of the container body 1 can be reliably maintained.

(Third Embodiment) FIG. 7 and FIG. 8 show a third embodiment.
An embodiment will be described. In this example, a pair of protrusions 21 are provided on the outer surface of the lower portion of the container body 1, and locking pieces 22 for locking the protrusions 21 are integrally formed on the upper portion of the container body 1. The locking piece 22 has elasticity, and a locking hole 23 is formed at the tip of the locking piece 22.
By compressing the container body 1 and hooking the locking hole 23 of the locking piece 22 on the protrusion 21 in the same manner as described above, the compressed state of the container body 1 can be reliably maintained as shown in FIG. 8.

In the case of FIG. 7 and FIG. 8, the member for maintaining the compressed state of the container body 1 is integrally formed, so that the user of the container body 1 is more convenient and convenient. Discarding is performed with the compressed state maintained. Further, the locking piece 22 and the projection 21 are provided on the container body 1.
Since it is formed integrally with the, the increase in cost can be suppressed to a low level.

Although the case of drinking water has been described as the one that enters the container body 1, it is not limited to these. For example, the present invention can be applied to a container containing a liquid material such as a chemical agent or a drug or a solid material, and any container may be contained therein. In addition, the material of the container body 1 is compressed,
Any material can be used as long as it can form the expandable bellows portion 4.

[0021]

According to the container of claim 1 of the present invention,
A bellows portion which is vertically compressible is provided on the body of a cylindrical container body made of synthetic resin, and the bellows portion is formed over substantially the entire length in the up and down direction of the container body. Will be less bulky and will retain its compressed state. Therefore, it is not bulky when placed in a trash bag, and can be placed in the trash bag many times more than when it is not compressed. Therefore, the number of garbage bags is reduced, and the collection work by the garbage truck becomes easier. Also, even when it is landfilled as non-burnable garbage, the container body is still compressed, so the space for landfill can be smaller than that when it is not compressed, and if the landfill volume is the same, it will not be compressed. It is possible to fill up the container body many times more.
That is, if the number of container bodies is the same, the landfill can be reduced to a fraction or less. Further, when the container body is compressed, the amount of rainwater entering the container body is also reduced, and the rate of occurrence of bow hula and the like is also smaller than in the conventional case.
Therefore, the number of matters that cause illness can be reduced as much as possible. As described above, by carrying out the present invention, it is possible to cooperate with the environmental problem and greatly contribute to the solution of the garbage problem in the local government.

Further, according to the container of the second aspect, since the container body is provided with a member for retaining the compressed state of the container body by hooking and locking the container body from above and below, the compressed state of the container body is maintained. The volume of the container body can be further reduced and the effect described in claim 1 can be more exerted as compared with the case where the member for maintaining the compressed state is not used.

Further, according to the container of the third aspect, holding members are integrally formed on the upper and lower portions of the container body, and the upper and lower holding members are hooked and locked to hold the compressed state of the container body. Therefore, in addition to the effect described in claim 2, since the holding member is formed integrally with the container body, it is possible to suppress an increase in cost.
