It consists of 6.

The bracket 52 has a pair of side plates 57, 5.
7', and a connecting side plate 58 that connects one side edge of these side plates 57, 57'.
The lower side of each of 57' is notched in a chevron shape, and the side of the connecting side plate 58 of this notch extends downward, and both sides of the lower end form a contact part 59 that supports the sides of the mouth of the bottle. . In addition, this contact portion 59
The opposite side is a pressing part 60 that supports the upper surface of the crown.

However, since the bracket 52 is made of metal, it is difficult to precisely form the positional relationship between the contact part 59 that holds the mouth of the bottle and the pressing part 60 when opening the bottle, resulting in defective products. It was easy. In addition, since the contact portions 59 are provided on both sides of the hook 61 and come into contact with the protruding portion of the mouth of the bottle,
The contact portion 59 was easily worn, and the positional relationship between the contact portion 59 and the pressing portion 60 was likely to be misaligned, making it impossible to hold the mouth of the bottle in the correct position.

Therefore, the purpose of this invention is to solve the above problems.

[Means for solving problems]

In order to solve the above problems, this idea
The bottle opener was constructed as follows.

That is, an integrally molded inner cylinder consisting of a cylindrical part that covers the mouth of the bottle and a pair of opposing plate parts connected to the upper surface of the cylindrical part is accommodated in the outer cylinder so as to be able to move up and down. A fulcrum shaft is installed in the center of the pair of plate-shaped parts in the left-right direction, and a lever is swingably supported on this fulcrum shaft,
A through hole communicating with the inside of the cylindrical part is provided below the tip between the pair of opposing plate parts, and an operating rod is fit into this through hole so as to be able to move up and down, and the upper end of the operating rod is rotatably attached to the tip of the lever. A hook is formed at the lower end of the working rod, the working rod is urged inward by a spring, and the upper front surface of the working rod is brought into contact with the inner surface of the through hole to allow the rod to move inward. The lever is prevented from rotating, and a tension spring is interposed between the rear end of the lever and the tip side of the pair of opposing plate-shaped parts to bias the lever upward, and the lever is The end is locked to the inner surface of the outer cylinder, and a contact part that supports the side surface of the mouth of the bottle is formed on the inner peripheral surface of the opening of the cylindrical part below the working rod, and the contact part is opposite to the contact part. A pressing part that supports the upper surface of the crown was formed above the inner surface of the cylindrical part.

[Effect]

When you hold the outer cylinder and place the cylindrical part of the inner cylinder over the mouth of the bottle, the contact part formed on the inner peripheral surface of the opening of the cylindrical part comes into contact with the lower side of the mouth of the bottle, and the upper surface of the crown. comes into contact with a pressing portion formed above the inner surface of the cylindrical portion, and the hooking claw of the working rod comes into contact with the side surface of the mouth of the bottle below the crown.

Next, when the outer cylinder is pushed down, the inner cylinder rises and the rear end of the lever is pushed down against the biasing force of the tension spring, causing the lever to move towards the fulcrum shaft that is built between the pair of opposing plate-shaped parts of the inner cylinder. The operating rod attached to the tip of the lever is pulled upward within the through hole that communicates between the cylindrical part and the plate part of the inner cylinder.

In this way, when the working rod is pulled up,
Since the working rod is urged inward by a spring, the hooking claw of the working rod catches the lower edge of the crown, prying the crown open and opening the bottle.
