2. Description of the Related Art Since synthetic resin bottles are lightweight, so-called PET bottles made of polyethylene terephthalate are frequently used as bottle containers. However, these bottles are hardly collected and reused in the bottle shape. At present, most of them are discarded as garbage. But,
PET bottles are hollow and bulky, making it difficult to handle when discarding from homes or when collecting waste. Therefore, various devices for cutting or crushing a PET bottle have been proposed. However, it is not easy to cut because it is hollow, and several places must be cut to reduce the volume. Also, as a method of crushing, conventionally there is a method of crushing or bending by applying pressure to the side,
Since many of these manual levers are used, the instrument body is large and heavy, and it is difficult to store it at home, and it is not easy to carry.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the following Examples, but it should not be construed that the invention is limited thereto. 1 to 3 show an example of an embodiment of the plastic bottle crusher of the present invention. 1 is a side view of an embodiment of the plastic bottle crusher of the present invention, FIG. 2 is a cross-sectional view of the plastic bottle crusher of FIG. 1 as viewed from the side, and FIG. 3 (a) is the plastic bottle crusher of FIG. View of the bottom part of the side of the tool viewed from the bottom,
(B) is the figure which looked at the bottom receiving part fitted with the side bottom part of (a) from the side part direction.

According to the present invention, there is provided a PET bottle crushing device in which a PET bottle accommodating portion for accommodating a PET bottle has an upper surface portion and a bottom receiving portion, and a side portion is vertically expandable and contractable. It is a cylindrical body that is slightly longer than the bottle and becomes a short cylinder when reduced. A plastic bottle with a lid removed is housed in the plastic bottle housing part, and a force is applied to the plastic bottle housing part from above and below, that is, the plastic bottle crusher of the present invention containing the plastic bottle is allowed to stand still, and limbs or the like are applied from the upper surface part. By applying a force or the like, the storage portion is reduced in the vertical direction, and accordingly, the stored PET bottle can be compressed in the vertical direction.

In the present invention, in the process of compressing the accommodated plastic bottle in the vertical direction, if the spout of the plastic bottle is sealed by the upper surface of the accommodation portion, the air in the plastic bottle inhibits the compression. Therefore, a small hole is provided in a portion of the upper surface portion facing the spout of the plastic bottle in order to allow the air to escape to the outside of the plastic bottle storage portion.

[0008] The shape of the PET bottle crusher of the present invention is not particularly limited as long as it has the above-described configuration.
The side of the PET bottle storage part temporarily becomes smaller in inner diameter 2
At least two cylindrical parts are connected, and the connected cylindrical parts can move with each other, become a long cylindrical body whose inner diameter becomes smaller temporarily when extended, and each tubular part is assembled into a nested state when shortened, It is preferable that the structure be a cylindrical body.

The connection of two or more cylindrical parts having a temporarily reduced inner diameter means that, as shown in FIGS. 1 and 2, one cylindrical part n ₁ is slightly larger than the inner diameter of n _1. small has an outside diameter, connects the tubular part n ₂ that can fit into nest state inside the n _1, sequentially similar tubular part n _3, n _4,
.. n ₅ ... At this time, the inner diameter may be smaller at the upper part of the tubular body at the time of extension, or the inner diameter may be larger at the upper part, but the larger the inner diameter at the upper part, it is easier to hold the PET bottle stably, and It is preferable because a load can be easily applied from the upper surface.

[0010] In such a case, by enabling the parts connecting the respective cylindrical parts to be slidably moved, the respective cylindrical parts are accommodated in a cylindrical part having a larger inner diameter, and finally, The PET bottle crusher according to the present invention can reduce the size of each of the tubular parts to a short tubular body in which the tubular parts are in the nested state. In addition, by preventing the connection state from being easily released, each tubular component can be pulled out from the telescopic state and can be extended to the long tubular body.

As a method of preventing the connection of each tubular part from being easily released so that it can be extended to the long cylindrical body, for example, as shown in FIG. In addition, a protrusion is provided so that the cylindrical parts to be connected to each other are hooked to each other, or as shown in FIG. 5, a groove is formed inside the side part of each cylindrical part, and the side part of the cylindrical part housed inside is provided. There is a method in which a protrusion that can slide inside the groove is provided outside, and a stopper is provided in the groove so that the protrusion does not come out of the groove.

As shown in FIGS. 1 and 2, the plastic bottle container of the plastic bottle crusher of the present invention has an upper surface portion and a side portion integrally formed or fixed, and a bottom receiving portion having a cylindrical shape at the lowermost side portion. A structure that can be attached to and detached from the part is preferable because the plastic bottle can be accommodated so as to cover the plastic bottle at the time of use, no extra operation is required, and the strength when crushing is excellent. In such a case, the shape of the bottom receiving portion is not particularly limited as long as the bottom receiving portion can be attached to and detached from the lowermost cylindrical portion of the side portion and can be left standing when the PET bottle is stored. It may have substantially the same shape as the lower cylindrical portion, or may have a shape that becomes a lid when the housing portion becomes a short cylindrical shape when reduced.

The shape of the plastic bottle container of the plastic bottle crusher of the present invention is not particularly limited as long as the plastic bottle intended to be crushed can be stably accommodated. It may be cylindrical.

The size of the plastic bottle container of the plastic bottle crusher of the present invention is not particularly limited as long as the plastic bottle for the purpose of crushing can be stably accommodated, but is approximately equal to the size of the plastic bottle for the purpose of crushing. Is preferably the same size. However, it is also possible to use a plurality of types of plastic bottles having different sizes as a size approximately equal to the largest size of plastic bottles generally distributed.

The plastic bottle crusher of the present invention may be provided with a depression or the like inside the upper surface or the bottom receiving portion so that the plastic bottle can be stably accommodated.

The material for forming the plastic bottle crusher of the present invention is not particularly limited as long as it does not break or deform when the plastic bottle is crushed. Examples of the material include plastics such as ABS resin and polyethylene terephthalate, metals, and wood. However, it is preferable to use plastic because it is rich in mass productivity and lightweight. In particular, since a large load is applied to the top portion and the bottom receiving portion when the PET bottle is crushed, it is preferable to use an ABS resin excellent in strength.

The plastic bottle crusher of the present invention can be molded by a commonly used molding method depending on the material used. For example, plastics can be molded by injection molding or the like.
