Description

[Technical field]

[0001] The present invention relates to a cap opener for easily opening and closing the caps of plastic bottles. [Background technology]

[0002] In recent years, as extremely hot days continue more and more frequently, especially in the summer, it is recommended to carry drinking water such as mineral water, green tea, barley tea, and sports drinks to stay hydrated as part of measures to prevent heatstroke. Many people carry drinking water in plastic bottles because it is easy to purchase from vending machines and stores. Summary of the Invention [Problem to be solved by the invention]

[0003] The caps of plastic bottles are tightly closed to prevent contamination by foreign objects and deterioration of the drinking water inside. Therefore, some people with weak grip strength and small hands, such as children, women, and elderly people, have difficulty opening the caps of plastic bottles.

[0004] The object of the present invention is to provide a technology for easily opening and closing the cap of a plastic bottle. [Means for solving the problem]

[0005] According to an aspect of the present invention, there is provided a cap opener for opening a cap of a plastic bottle, comprising: a cap cover portion having flexibility, an inner surface that abuts against an outer surface of the cap, and an outer diameter larger than an outer diameter of the cap; a protrusion protruding radially outward from the cap cover portion, The cap opener is characterized in that a through hole is formed in the protrusion. Effect of the Invention

[0006] According to the above configuration, when the cap opener is placed on the cap of a plastic bottle, the inner surface of the flexible cap cover abuts against the outer surface of the cap, so that the force applied to the cap opener can be transmitted to the cap. In addition, since the outer diameter of the cap cover of the cap opener is larger than the outer diameter of the cap, the cap opener can be turned with less force than when the cap is directly gripped and turned by utilizing the action of the wheel axle. A protrusion is provided from the cap cover part, protruding radially outward. Therefore, the user can hook his / her finger on the protrusion and easily grip the cap opener. This makes it possible to easily transmit the force in the rotational direction for opening the cap to the cap opener. Since the protrusion is provided with a through hole, the portability of the cap opener can be improved by, for example, attaching a carabiner to the through hole. [Brief description of the drawings]

[0007] [Figure 1] FIG. 1 is a schematic explanatory diagram of a cap opener 100 according to an embodiment of the present invention. [Diagram 2] FIG. 2 is a top view of the cap opener 100. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] A cap opener 100 according to the present invention will be described with reference to the drawings. In the following description, a cap opener 1 for opening a cap 2 of a plastic bottle 1 will be taken as an example.

[0009] Fig. 1 is a schematic explanatory diagram of a cap opener 100 according to this embodiment. Fig. 2 is a diagram of the cap opener 100 as viewed from above.

[0010] As shown in Fig. 1, the cap opener 100 is attached from above to the cap 2 of the plastic bottle 1. With the cap opener 100 placed over the top of the cap 2, a user can rotate the cap 2 and remove it from the plastic bottle 1 by gripping and rotating the cap opener 100.

[0011] 1 and 2, the cap opener 100 has a cap cover part 110 having a substantially hemispherical outer shape, and a protruding part 120 protruding radially outward from the cap cover part 110. Inside the cap cover part 110, a hollow space having approximately the same shape as the outer shape of the cap 2 of the PET bottle 1 is formed. In other words, the inside of the cap cover part 110 is contoured so that a space having approximately the same shape as the outer shape of the cap 2 of the PET bottle 1 is formed. Therefore, the cap opener 100 is attached onto the cap 2 by inserting the cap 2 into the hollow space of the cap cover part 110.

[0012] Alternatively, the inner surface of the cap cover part 110 may be contoured to form a hollow space having a substantially hemispherical shape. In this case, the inner diameter of the inner surface of the cap cover part 110 is largest at the lower end and gradually decreases toward the upper end. Even in this case, when the cap cover part 110 is placed on the cap 2, the inner surface of the cap cover part 110 abuts against the outer surface of the cap 2.

[0013] By turning the cap opener 100 with the inner surface of the cap cover part 110 abutting against the outer surface of the cap 2, the force applied to the cap opener 100 can be transmitted to the cap 2, making it possible to easily open the cap 2. Since the outer diameter of the cap opener 100 is larger than the outer diameter of the cap 2, the action of the axle can be used to turn the cap opener 100 with less force than when the cap 2 is directly gripped and turned.

[0014] The inner surface of the cap cover part 110 may be provided with a plurality of grooves extending in the vertical direction. In this case, the uneven portion formed by the plurality of grooves abuts against the outer surface of the cap 1A, so that the frictional resistance between the outer surface of the cap 2 and the inner surface of the cap cover part 110 can be increased. This makes it possible to reduce the force required to open the cap 2.

[0015] The cap cover part 110 is formed with a protrusion 120 that protrudes radially outward. Therefore, a user can easily grip the cap opener 100 by hooking his / her fingers on the protrusion 120, and the force in the rotational direction for opening the cap 2 can be easily transmitted to the cap opener 100. As a result, the cap 2 of the plastic bottle 1 can be opened with less force than if the protrusion 120 was not provided.

[0016] 2, the protruding portion 120 is provided with a carabiner hole 121. The carabiner hole 121 is a through hole for attaching a hook member such as a carabiner, a key holder, or the like. For example, by attaching a carabiner to the carabiner hole 121, the cap opener 100 can be easily attached to the handle of a bag, or the like. This can improve the portability of the cap opener 100.

[0017] The cap opener 100 of this embodiment is made of polypropylene resin made from waste plastic. Waste plastic refers to waste such as plastic fragments discharged from business activities and unnecessary plastic products. Using waste plastic as a raw material to manufacture polypropylene resin products such as the cap opener 100 can contribute to reducing environmental burden and making effective use of resources, and is therefore preferable from the viewpoint of recycling.

[0018] The present invention is not limited to the above description, and can be modified within the scope of the present invention. For example, the cap opener 100 of the present invention does not necessarily have to be made of polypropylene resin made from waste plastic, and may be made of newly produced polypropylene resin. In addition, the cap opener 100 does not necessarily have to be made of polypropylene resin as long as it is made of a flexible member. The cap opener 100 may be made of, for example, plastic resin other than polypropylene resin, silicone resin, rubber, etc.

[0019] In the above embodiment, the cap cover part 110 of the cap opener 100 has a substantially hemispherical outer shape. However, the present invention is not limited to such an embodiment, and the outer shape of the cap cover part 110 can be any suitable shape. For example, a cylindrical shape, a prismatic shape, a truncated cone shape, a truncated pyramid shape, etc. can be adopted.

[0020] In the above embodiment, the cap opener 100 has one protrusion 120, but the present invention is not limited to such an embodiment. The cap opener 100 may be provided with a plurality of protrusions 120. [Explanation of symbols]
