Description

[Detailed Description of the Invention] The present invention relates to a bottle opener. In conventional bottle openers, when you apply the bottle opener to the bottle opening to open the bottle, you apply it too deeply and use too much force to open the bottle, causing damage to the glass bottle opening. This caused a safety problem as gas particles generated by the notch could get into the drink.

FIG. 8 is an explanatory view showing the opening state of a conventional bottle opener A, in which the teeth D for opening the crown C which is placed on the bottle mouth BT have a flat plate shape. To open the bottle, place the teeth D of the bottle opener A on the lower end of the folded end E of the crown C, and rotate the bottle opener A in the direction of the arrow H, which is approximately perpendicular to the longitudinal direction of the handle G, using the fulcrum F as the rotational fulcrum. and remove the crown C from the bottle mouth BT. A packing layer Z made of cork, polyethylene, etc. is mounted on the back of the crown C. During this opening operation, the tip J of the tooth D rotates about the fulcrum F in the direction of arrow H, which is substantially perpendicular to the longitudinal direction of the handle G. For this reason, the tooth tip J
If it bites deeply in the longitudinal direction of the handle G in the direction of the arrow There were safety issues such as the possibility of the product getting into the interior of the vehicle. However, as a physical characteristic of glass, it is extremely weak against tensile stress, so the cracking phenomenon occurs when an extremely large tensile stress is generated locally at the bottle mouth BT.

This invention was proposed to solve the above-mentioned drawbacks, and it prevents the teeth of the bottle opener teeth from coming into contact with the bottle mouth during the opening operation, and provides a good and strong structure that facilitates the opening operation. An object of the present invention is to provide a connecting bottle opener having the following features.

Hereinafter, the present invention will be described based on embodiments with reference to the drawings. FIG. 1 is a front view of an embodiment of the present invention, and 1A and 1B are conventional well-known bottle openers having the same shape. As shown in the side view of FIG. 2, the bottle openers 1A and 1B are tightly connected by a connecting member 2 in substantially parallel to each other in the same direction.
To explain the means for connecting the bottle openers 1A and 1B, they are connected by a hollow cylindrical connecting member 2 shown in the plan view of FIG. 3 and the side view of FIG. 4. The connecting member 2, which is the connecting means, has the property of shrinking when heated, and is preferably made of vinyl chloride, ethylene propylene rubber, or the like. This connecting means may be a member having physical shrinkage such as rubber, cloth,
It may be wrapped with metal foil or the like, or simply known connection means such as welding or adhesive bonding may be used. As shown in Figure 5, the bottle opener 1
A and 1B are brought into close contact with each other in the same direction and substantially parallel to each other, and inserted into the hollow part of the connecting member 2 so that the handles 3A and 3B are almost entirely wrapped. After this, connecting member 2
When heated, it contracts and the bottle openers 1A and 1B are tightly connected as shown in FIGS. 1 and 2.
Since the bottle openers 1A and 1B are connected to each other, the structure is strong. Moreover, this connecting member 2 is
The texture is smooth and pleasant, and the handle is thick, making it easy to open the bottle. Figure 6 shows
The handle 3A shows the open state according to an embodiment of the present invention.
The bottle openers 4A and 4B provided at one end of 3B are crown C
This is the part that opens the bottle from the bottle mouth BT. Openings 5A, 5B formed inside the bottle openers 4A, 4B
Bottle opener teeth 7A, 7B are provided on the inner peripheral edges 6A, 6B near the handles 3A, 3B. The bottle openers 1A and 1B are closely connected so that the teeth 8A and 8B of the bottle opener tooth portions 7A and 7B having substantially the same shape as each other have the same tooth depth from the root and the tooth tips 9A and 9B are substantially aligned. The tooth tips 9A, 9B are formed as planes substantially perpendicular to the direction of arrow X, which is the longitudinal direction of the handles 3A, 3B.
It may have a protruding shape instead of a planar shape. Tooth tip 9A,
The sides continue in a widening shape from both edge lines of 9B to the base of the teeth. It is preferable that both edge line portions of the tooth tips 9A and 9B become curved surfaces. Bottle opening BT when emptying and opening
This is to prevent damage to the In order to provide the required spacing between the teeth 8A and 8B, the handles 3A and 3B are provided with handle extraction tooth portions 7.
The thickness increases from near the boundary with A and 7B. When opening the bottle, use handles 3A and 3B as shown in Figure 7.
The inner peripheral edge on the opposite side is placed slightly further back than the center line FA of the crown C, and a fulcrum line F for rotation is set. As shown in Figure 6, the outer edge of the crown end O
is in contact with the edge line of the tooth 8A, and the inner edge I of the crown end is in contact with the side surface of the tooth 8B. Therefore, excessive biting of the tooth 8B in the direction of the arrow X is prevented, and the bottle mouth BT
No gap phenomenon occurs at the outer circumferential end M of.
In other words, the distance l from the supporting point F to the farthest bulging part N of the outer peripheral end M of the bottle mouth BT is always the supporting point F.
The tooth 8B is configured so that the distance L from the tip 9B of the tooth 8B to the tip 9B of the tooth 8B is always kept smaller than the distance L from the tip 9B of the tooth 8B.
and 1B are closely connected. In order to always keep the distance l smaller than the distance L, the tooth depths of the teeth 8A and 8B and the spacing between the teeth 8A and 8B that are opposed to each other are adjusted. If this adjustment is not appropriate, the outer peripheral end M of the bottle mouth BT will be damaged due to excessive biting of the teeth 8B in the direction of the arrow X. Note that even if the bottle is turned inside out, the bottle can be opened in the same manner as described above. In this case, the outer edge O of the crown end comes into contact with the edge line of the tooth 8B, and the inner edge I of the crown end comes into contact with the side surface of the tooth 8A. At this time as well, excessive biting of the teeth 8A in the direction of the arrow X is prevented, and the phenomenon of cracking of the bottle mouth BT does not occur. In other words, the teeth 8A and 8 serve as a stopper that prevents excessive biting into each other in the direction of the arrow X.

As explained above, in the present invention, bottle openers of the same shape are tightly connected by a connecting means, so that the teeth of each other act as a stopper, preventing excessive digging of the teeth, and eliminating the phenomenon of a gap at the bottle opening. Also, since they are connected, they have a strong structure and are easier to open.
