JP3063395U - PET bottle cutter - Google Patents

Abstract

(57) [Summary] [Problem] PET bottles (polyethylene terephthalate bottles) are targeted for resource recycling. However, not all PET bottles are made of polyethylene terephthalate. In particular, foreign materials are used for the plug and the plug receiving portion. In the state where the foreign materials are mixed, the foreign materials cannot be used as a recycled material, so the foreign materials are removed. However, this work process is very time-consuming and expensive, and hinders reuse. SOLUTION: In order to promote the reuse of plastic bottle resources, a plastic bottle cutter which can easily separate a plug and a plug receiving portion of a plastic bottle used in each household from a main body is provided.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a plastic bottle cutter mainly used for cutting the neck of a plastic bottle.

[0002]

[Prior art]

 PET bottles are collected and used as reusable resources. However, all PET bottles are not made of polyethylene terephthalate but are made of different materials. Specifically, foreign materials such as a plug, a plug receiving part, and a product display film wrapped around the body are incorporated. If foreign materials are incorporated, they cannot be used as recycled materials. Therefore, conventionally, a foreign material is separated after pulverization (Japanese Utility Model Laid-Open No. 4-9517), a protective cover is separated by hot water as disclosed in Japanese Patent Application Laid-Open No. 4-229210, or (Japanese Utility Model No. 10-305773). It has been proposed to attach the blade to a part of the scissors and remove the plug receiving part.

[0003] However, of the above (JP-A-4-229210) and (JP-A-4-9517), the cost is too high for resource recycling. Further, in Japanese Utility Model Application Publication No. 10-305773, the blade body hits the hard part of the plug receiving portion of the plastic bottle when used at home, and cannot be used by a person with weak power. Also, it cannot be used for plastic bottles with a large plug. Therefore, the present invention aims to contribute to the promotion of resource reuse by proposing a new PET bottle cutter.

In the plastic bottle cutter according to the present invention, two rod-shaped materials are joined at one end so that they can be opened and closed with respect to the center of the two rod-shaped materials. The present invention is characterized in that a concave portion is formed and a neck cutting mechanism for a plastic bottle is provided in which a cutting blade is provided in one or all of the curved concave portions.

[0005] Furthermore, a certain height is provided in the vertically curved concave portion of the blade body portion, and one is perpendicular to the blade and the other is at an angle of 90 degrees or more from the blade.

[0006] Further, a waveform is provided in the curved concave portion.

[0007]

[Action]

 Therefore, the blade portion is easily inserted into the PET bottle by gripping the neck portion of the PET bottle with the blade portion of the curved concave portion, and the handle portion can be moved in a circular motion around the neck portion of the PET bottle. The neck is easily cut off.

[0008]

【Example】

 Next, an embodiment of the present invention will be described. The cutter for plastic bottles shown in the embodiment is formed of two rod-shaped materials that are not easily bent, and forms a joint 1 in which one end is joined so as to be able to open and close each other around that part. Curved concave portions 41 and 42 corresponding to the neck portion of the plastic bottle are formed in opposed portions, the blade body 2 is projected from the curved concave portions, and a handle portion 3 is provided at the other end.

The opening and closing of the handle portion 3 can be extremely reduced by increasing the distance between the curved concave portions 41 and 42 from the joint portion 1. In addition, by providing a fixed height in the vertically curved concave portions 41 and 42 of the blade body portion 2 and making one of them perpendicular to the blade, the blade body portion can keep a certain distance from the plug receiving portion of the PET bottle. The blade can be inserted into the soft part of the bottle's plug receiving part instead of the hard part, and the other is at an angle of 90 degrees or more from the blade to cope with the spread toward the bottom of the pet bottle.

[0010] Further, by providing the curved concave portion with a corrugated portion, the neck portion of the plastic bottle is sandwiched by a line instead of a surface, so that it is very easy to move the handle portion.

[0011]

[Effect of the invention]

 As described above, the present invention provides a device that can easily cut the neck of a PET bottle in each household regardless of the size of the PET bottle, and that is convenient for processing when the PET bottle is used as a resource. In addition, it will reduce the cost of reprocessing and contribute to promoting the reuse of resources.

Claims (3)

[Utility model registration claims] An end of two rod-shaped materials is joined to each other so that they can be opened and closed about the portion, and a curved concave portion corresponding to a neck portion of a plastic bottle is formed in an opposing portion, and a curved concave portion is formed. A plastic bottle cutter comprising a plastic bottle neck cutting mechanism provided with a cutting blade in one or all parts thereof, and the other end not joined as a handle. 2.
