Description

[Technical Field]

[0001] This specification discloses a technique related to a plug opener. [Background technology]

[0002] A bottle opener for a bottle cap is a tool used to remove the cap that seals a bottle, such as a 1.8L bottle or a 480ml bottle, from the bottle's neck. When removing the cap from the bottle's neck, it is necessary to carefully open the bottle while holding down the cap so that the cap does not fly off or the contents do not boil over. In particular, in the case of sparkling sake, the internal pressure of the bottle is relatively high and the cap tends to be designed to fit tightly with the bottle neck, making it necessary to open the bottle even more carefully. The bottle opener in Patent Document 1 comprises an insertion part into which the cap is inserted and a retaining plate spaced from the insertion part to hold down the flange of the cap.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-157597 Summary of the Invention [Problem to be solved by the invention]

[0004] The plug-in bottle opener of Patent Document 1 has a complicated structure due to the need to form a presser plate, compared to a normal bottle opener, and therefore has the problem of increased manufacturing costs. [Means for solving the problem]

[0005] The technology disclosed in this specification can be realized in the following forms.

[0006] One embodiment disclosed herein is a bottle opener for a bottle cap. This bottle opener is a thin stainless steel plate that fits in the palm of your hand. The bottle opener has a through hole that forms a shape combining a first circle with a diameter of 30.5 mm to 33.5 mm and a second circle with a diameter of 20.5 mm to 25.5 mm, the shape of which is determined by a linear movement from the inside to the outside of the first circle. A user of this type of bottle opener holds the bottle opener in their palm and passes the flange of the bottle through the portion of the through hole that corresponds to the first circle. Then, the user inserts the portion of the through hole that corresponds to the second circle between the flange of the bottle and the bottle mouth, and while holding the bottle opener with their palm, prys the bottle opener open, thereby removing the bottle cap from the bottle. In this way, the plug-in bottle opener of this embodiment can carefully open a plug by holding it down, with a relatively simple structure that does not require a holding plate. Therefore, the manufacturing cost of a plug-in bottle opener that can carefully open a plug by holding it down can be reduced. Furthermore, by inserting the portion of the through-hole corresponding to the first circle into the head or neck of the bottle, the plug-in bottle opener can be attached to the bottle for storage.

[0007] The technology disclosed in this specification can be realized in various forms other than a plug opener, such as a method for manufacturing a plug opener and a method for opening a plug. [Brief explanation of the drawings]
