Abstract

PROBLEM TO BE SOLVED: To provide a corkscrew for a wine bottle or the like wherein instantaneously large force is not required at all and operating force from an early operation period to uncorking is constantly light, so that a weak person can easily uncork. SOLUTION: The corkscrew comprises an air feed needle 4 vertically sticking through a cork of a wine bottle which is placed to communicate with the interior at a tip 5a of an outer cylinder, and a check valve 8 placed at a tip of an air feed cylinder 7 constituting an air reservoir 6 at a required distance from an inner diameter surface 5b of the outer cylinder and an internal surface 5a1 at the tip of the cylinder wherein the valve 8 is placed in the outer cylinder. A piston rod 12 including a handle 10 at an external end and a lower seal member 11 at an opposite lower end is fitted inside the air feed cylinder 7.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to corkscrew removal of wine bottles and the like.

[0002]

2. Description of the Related Art Conventionally, corkscrew removal of wine bottles, etc.
Numerous types, such as a coil wire type and a screw screw type, have been proposed.

[0003]

A coil wire type in which a coil wire is pierced into the conventional cork stopper and a pattern is integrally formed with the coil wire and pulled out requires a large pulling force in the initial stage of drawing. Suitable for men with strong abilities.
The screw screw type does not require a large pulling force because the handle is rotated and pulled out gradually. However, there are drawbacks such as a complicated mechanism.

The present invention has been made to solve such a disadvantage, and does not require any instantaneous large force at all. The operating force from the initial stage to opening is constant and light, and a weak person can easily open. It is intended to propose a cork stopper for a wine bottle or the like which can be stoppered.

[0005]

An air feeding needle for vertically penetrating and penetrating a cork stopper of a wine bottle is communicated with the inside of the outer cylinder at the distal end of the outer cylinder. A check valve is placed at the end of the air supply cylinder that forms an air reservoir, separated from the inner surface of the end, as required, and is arranged in the outer cylinder. There is a cork stopper for a wine bottle or the like in which a handle portion is fitted and provided with a piston rod having a descending seal member at an opposite lower end.

[0006] A support cylinder may be provided at the end of the outer cylinder so as to be slidably connected to the outer peripheral surface of the outer cylinder.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An air feeding needle for vertically penetrating and penetrating a cork stopper of a wine bottle is provided in communication with an inner end of an outer cylinder of an outer cylinder. A check valve is arranged at the tip of the air supply cylinder, which constitutes an air reservoir separated from the inner surface as required, and is arranged in the outer cylinder. A cork stopper for a wine bottle or the like, which is equipped with a piston rod fitted with packing at the opposite lower end and equipped with a support cylinder at the end of the outer cylinder that is slidably connected to the outer peripheral surface of the outer cylinder.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a corkscrew for wine bottles and the like according to the present invention;
More specifically, an air feeding needle 4 penetrating the cork stopper 3 of the wine bottle 2 up and down and penetrating the cork stopper 3 is provided in communication with the inside of the outer tube tip 5a of the outer tube 5, and the inner diameter of the outer tube 5 Face 5
and an air supply cylinder 7 constituting an air reservoir 6 apart from the inner diameter surface 5b of the outer cylinder and the inner surface 5a1 of the tip of the outer cylinder and a check valve 8 at the tip 7a. The air supply cylinder 7 is provided with a handle portion 10 at the outer end and a lower seal member at the opposite lower end as a descending seal member, for example, a packing 11. The supporting cylinder 1 fitted with the piston rod 12 fitted therein and slidably coupled to the outer cylinder outer peripheral surface 5c at the tip of the outer cylinder 5
3 is equipped. Numeral 14 denotes an air feeding needle cover, which is detachably attached to the outer tube tip 5a.

[0009] Cork stopper for wine bottles and the like of the present invention 1
Is configured as described above, so as shown in FIG.
The support cylinder 13 is fitted to the mouth 2a of the wine bottle 2 to support the whole, and then the outer cylinder 5 is pushed down to pierce the tip of the air supply needle 4 into the cork stopper 3 to thereby make the air supply needle 4 Is disposed in the wine bottle 2. Therefore, when the other hand is hung on the handle 10 to reciprocate the piston rod 12 up and down, when the piston rod 12 descends, the tip of the piston rod 12 is hermetically sealed with a packing 11 as a descending seal member, for example. The air inside the air supply cylinder 7 is ventilated by the vent hole 9 at the tip.
From the air reservoir 6. Then, the air is not returned to the air feeding cylinder 7 by the check valve 8, and the air compressed and sent out by the lowering operation of the piston rod 12 is introduced into the wine bottle 1 through the air feeding needle 4 communicating with the air reservoir 6. Will be fed. When the piston rod 12 rises, the air supply cylinder 7 is evacuated, so that the packing 11 bends and sucks external air into the air supply cylinder 7 to raise the piston rod 12 without resistance.
The air enriched in the wine bottle 1 pushes the cork stopper 3 outward. At this time, since the support cylinder 13 is supported integrally with the wine bottle 2, the cork stopper 3 and the outer cylinder 5 are integrally slid upward in the support cylinder 13 and come off. It is supported by the tube 13.

[0010]

The corkscrew removal of a wine bottle or the like according to the present invention is as described above. The air compressed by the air supply cylinder by the reciprocating motion of the piston rod flows through the ventilation hole of the air supply cylinder. The air is fed into the wine bottle through the air reservoir through the non-return valve, and the air is fed from the air reservoir into the wine bottle through the air supply needle. As in the case of feeding, there is no need to force the air into the narrow air path within the small diameter of the air feed needle with the force of the piston rod, and it is only necessary to send light operating force up and down repeatedly to the air reservoir. Therefore, a large pulling force is not required in the initial stage of opening.

When the support cylinder is slidably connected to the bottle opening body, the air supply needle is covered inside the support cylinder, and the air supply needle is safely and easily attached to the center of the cork stopper of the wine bottle. It can be pierced.

Therefore, it is possible to provide a cork bottle opener such as a wine bottle or the like which does not require any instantaneous large force, has a constant operating force from the initial stage to opening, and is light in weight, and can be easily opened by a weak person. Things.
