JP3081501U - Convex cap - Google Patents

Abstract

(57) [Summary] (Modifications required) [Problem] To easily open a cap such as a plastic PET bottle even when the lid is opened for the first time, in a wet state without slipping and without applying strong force. Be able to close the lid. SOLUTION: A cap 1 such as a plastic PET bottle is provided with a plurality of projections 2 having a shape of an isosceles triangle on a side surface of a cylindrical shape at a plurality of positions, and a portion to which a finger is applied at the time of opening the lid is easily set to apply force. Because of this, and because the tip corner 3 of the projection is slightly rounded, the cap can be easily and reliably opened and closed with a small force without hurting a finger or the like at the corner.

Description

[Detailed description of the invention]

[0001]

[Prior art]

 Conventionally, caps such as plastic PET bottles that have been sold have a columnar shape and have only non-slip vertical streaks on the sides.

[0002]

[Problems to be solved by the invention]

 Conventional caps, such as plastic PET bottles, are harder to slip open when wet, and when the cap is opened for the first time, it is not possible to specify where the force is applied.

[0003] In particular, in the case of weak children and elderly people, the place where the force is applied is not fixed at the time of the first opening operation that requires the power, and the finger slips, so it is difficult to open the finger and further power is required. .

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the convex cap of the present invention attaches an isosceles triangular convex part to the cylindrical side surface of a conventional cap such as a plastic PET bottle at a plurality of locations, and forms a tip angle. The section is slightly rounded so that it does not hurt even if your finger hits it.

[0005]

【Example】

 When using the convex cap of the present invention when opening the cap of a plastic PET bottle, etc., the finger will be turned around the convex part, so less power is required, and the finger will not slip and become firm. The lid can be opened.

Further, since the tip corner of the convex portion is round, it can be opened extremely easily without giving any pain to the finger during operation.

[0007] Even when closing, the lid can be lightly closed with little force because a finger is applied to the convex portion.

[0008] The bottom corners of the convex portion, which is the connecting portion between the convex portion and the cap body, are. Increase the thickness to maintain the strength of the protrusions.

[Effect of the invention]

 The convex cap of the present invention can be used not only when closing the cap, but also especially when opening the cap for the first time, even if the person has weak force. There is an effect that the cap can be opened and closed without the need.
