Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a corkscrew opening machine for removing a cork stopper from a bottle tightly sealed with a wine bottle or another cork stopper.

[0002]

[Prior art]

 Conventionally, as a corkscrew for this cork stopper, a machine in which a handwheel is provided at the rear end of the drill is known. When using this bottle opener, the tip of the drill was pushed into the center of the upper surface of the cork with the bottle mouth tightly closed, and the drill was directly rotated deeply into the cork stopper while being manually rotated using the handle. Then pull up on the handle to pull the cork stopper out of the bottle mouth.

[0003]

[Problems to be solved by the device]

 However, this conventional bottle opener must be rotated while holding the handle by hand so that the drill is always perpendicular to the top of the cork in order to immerse the drill straight and deep. However, it is not easy to immerse the drill in a straight line because the drill easily shakes when it is turned manually. Therefore, if it is repeatedly immersed or withdrawn, the inside of the cork stopper will eventually be destroyed, and the cork stopper may not be able to be pulled out from the bottle mouth. Even if the drill is deeply immersed in the cork stopper, it is necessary to pull up the handle strongly to pull the cork stopper out of the bottle mouth.

[0004] Therefore, the present invention is for a cork stopper that can surely immerse the drill straight and deep into the cork stopper and that can be easily pulled out without strongly pulling the cork stopper from the bottle mouth. It is an object of the present invention to provide a bottle opener.

[0005]

[Means for Solving the Problems]

 In order to solve this problem, the present invention rotatably supports a downwardly directed drill 30 on the same axial center above a cylindrical guide holder 20 into which a bottle mouth is inserted, and attaches it to an inner peripheral wall of the guide holder 20. A bottle mouth stopper 21 through which the end face of the bottle mouth comes into contact and a cork stopper passes through is provided, and the tip 32 of the drill 30 is located between the bottle mouth stopper 21 and the lower end of the guide holder 20. Configured a bottle opener.

[0006]

[Action]

 In the corkscrew opening machine according to the present invention having the above-mentioned configuration, when the bottle mouth M tightly sealed by the cork stopper C is inserted from the lower end of the guide holder 20, the tip of the drill hits the upper surface of the cork stopper C. Contact. When the rotation (normal rotation) of the drill 30 is started in this state, the drill 30 begins to sink into the cork stopper C, and the cork stopper C rises in the guide holder 20 as it is retracted, and is caused by the rotation of the drill 30. The force to raise the cork stopper C becomes the force to raise the bottle mouth M as it is through the frictional resistance between the bottle mouth M and the cork stopper C which try to retain the cork stopper C in the bottle mouth M. The bottle mouth M also rises with the stopper plugged, and eventually the bottle mouth M contacts the bottle mouth stopper 21. When the drill 30 is further rotated, the cork stopper C starts to rise against the frictional resistance with the tightly stoppered bottle mouth M, passes through the bottle mouth stopper 21, and is finally withdrawn from the bottle mouth M.

Embodiment 1 The corkscrew opener for corkscrews according to the embodiment shown in FIGS. 1 and 2 is a manual type, and includes a guide holder 20 and a drill 30 supported on the upper end of the guide holder 20 with the same axis. Made of.

The guide holder 20 includes a bottle mouth guide portion 22 having a large inner diameter, and a narrow stopper inner guide portion 23 provided on the bottle mouth guide portion 22. A step formed by the upper and lower inner diameters is a bottle mouth stopper 21. (See Figure 1). Since the outer diameter of the bottle mouth M of a bottle used for wine or the like is about 2.5 cm, and the cork stopper C used for this has a diameter of about 2 cm and a length of about 5 cm, the guide holder 20 has an inner diameter of 2. 6 cm, the length is about 5.5 cm, and the cork stopper guide portion 23 has an inner diameter of 2.1 cm and a length of 5. It is preferably about 5 cm.

On the wall surface of the cork stopper guide portion 23, a pair of cork stopper holding claw pieces 29 are provided so as to face each other. The cork stopper holding claw piece 29 may be formed by cutting out the wall surface, but it may be formed separately from the wall surface. The guide holder 20 is preferably made of an elastic material such as hard plastic or metal so that the cork stopper holding claw 29 is pressed and bent inward.

The corkscrew opening machine according to this embodiment is used as follows.

The bottle mouth M with a tight stopper is inserted into the bottle mouth guide portion 22 of the guide holder 20, and the upper surface of the cork stopper C is brought into contact with the tip 32 of the drill (see FIG. 1A).

In this state, rotation (normal rotation) of the drill 30 is started. As a result, the tip 32 of the drill 30 gradually sinks into the cork stopper C, and along with this, the bottle mouth M gradually rises in the bottle mouth guide portion 22 together with the tightly closed cork stopper C, and the bottle mouth M becomes a bottle. It abuts the mouth stopper 21 (see (B)).

When the drill 30 is further rotated, the tightly closed cork stopper C begins to rise against the frictional resistance with the bottle mouth M, passes through the inner diameter of the bottle mouth stopper 21, and finally from the bottle mouth M. When the cork stopper C is pulled out, the lower end of the cork stopper C is left slightly inside the bottle mouth M and idles together with the drill 30 (see the solid line in FIG. 6C).

In this state, the cork stopper C does not simply leave its lower end slightly inside the bottle mouth M, and the bottle mouth M is not tightly closed. The cork stopper C can be removed.

The cork stopper C pulled out from the bottle mouth M remains in the cork stopper guide portion 23. To remove the cork stopper C, the cork stopper guide portion 23 is removed as shown in FIG. The provided cork stopper holding claw piece 29 is pressed, the cork stopper C is held by the claw piece 29 bent inward, and the drill 30 is rotated in the reverse direction. The cork stopper C sandwiched by the claw pieces 29 is pushed downward with the rotation of the drill 30 that is immersed without being idled, pushed out from the lower end of the guide holder 20, and removed.

[0016]

[Embodiment 2] The corkscrew opener for the cork stoppers of the embodiments shown in FIGS. 4 to 8 is of an electric type, and includes a case 10, a guide cylinder 15 protruding downward from the case 10, and the guide cylinder. It comprises a guide holder 20 supported by 15, a drill 30 arranged on the axis of the guide cylinder 15, and a power means 40 for rotating the drill 30.

The guide holder 20 includes a bottle mouth guide portion 22 having a wide inner diameter, and a narrow stopper inner guide portion 23 provided on the bottle mouth guide portion 22, and a step formed by the upper and lower inner diameters serves as a bottle mouth stopper 21. (See Figure 4).

A winding spring 61 is provided between the bearing 35 and the upper wall 27 of the guide holder 20 as a biasing means for biasing the guide holder 20 downward. The drill 30 is arranged at the axis of the guide holder 20 and is rotatably supported by a bearing 35 provided in the case 10. The tip 32 of the drill 30 is located about 1 cm below the bottle mouth stopper 21 in the guide cylinder. Preferably.

The power means 40 is composed of a DC motor 41, spur gears 42, 43 and 44, a pinion 45, a spur gear 46, etc. The rotation of the motor 41 is sufficiently decelerated by these to increase the torque and increase the drill. 30 is transmitted. The motor 41 is driven by a dry battery 51 housed in the case 10, and a power switch 52 is provided between the battery 51 and the motor 41. This switch 50 uses two interlocking circuits and three contact points. As shown in FIG. 7, not only ON and OFF, but also the forward and reverse operations of the drill 30 can be performed by switching the polarity. it can.

The corkscrew opening machine according to this embodiment is used as follows.

The tightly stoppered bottle mouth M is inserted into the bottle mouth guide portion 22 of the guide holder 20, and the upper surface of the cork stopper C is brought into contact with the tip 32 of the drill (see FIG. 6A).

In this state, the switch 50 is turned to the normal rotation side, and the rotation of the drill 30 (normal rotation) by the power means 40 is started. As a result, the tip 32 of the drill 30 gradually sinks into the cork stopper C, and along with this, the bottle mouth M gradually rises inside the bottle mouth guide portion 22 together with the cork stopper C that tightly closes, and the bottle mouth M becomes the bottle mouth stopper. 21 (See (B)).

When the drill 30 is further rotated, the force to raise the cork stopper C generated by the rotation of the drill 30 is increased by the force of the bottle mouth M to retain the cork stopper C in the bottle mouth M. The friction force between the cork stopper C and the cork stopper C acts as a force to raise the bottle mouth M as it is. Therefore, as the cork stopper C is raised, the bottle mouth M is kept closed by the cork stopper, and the spring body 61 is used. As the guide holder 20 is pushed up against the bias, it rises and the drill 30 deeply sinks into the cork stopper C (see the broken line in (C)).

As the guide holder 20 rises in this way, the force for urging the guide holder 20 downward by the spring body 61 gradually increases, and eventually the guide holder 20 is maintained while being tightly plugged with the cork stopper C. When the force of the bottle mouth M that pushes up and rises and the force of the guide holder 20 that pushes back the bottle mouth M by being biased by the spring body 61 antagonize each other and exceeds the balance point of both, The tightly stoppered cork stopper C passes through the inner diameter of the bottle mouth stopper 21 and starts to rise against the frictional resistance with the bottle mouth M, and is finally pulled out from the bottle mouth M, and the cork stopper C is slightly lowered at its lower end. Leave the inside of the bottle mouth M and run idle with the drill 30 (see the solid line in the same (C)).

In this state, the cork stopper C does not simply leave its lower end slightly inside the bottle mouth M, and since the bottle mouth M is not tightly closed, the bottle mouth M can be lifted only by lifting the bottle opener. The cork stopper C can be removed from it.

The cork stopper C removed from the bottle mouth M remains in the cork stopper guide portion 23. To remove the cork stopper C, the cork stopper holding claw piece provided in the cork stopper guide portion 23 is used. 29 is pressed, the cork stopper C is clamped by this inwardly bent claw piece 29, and the drill 30 is reversely rotated by the switch 50. The cork stopper C sandwiched by the claw pieces 29 is pushed downward with the rotation of the immersed drill 30 without idling, is pushed out from the lower end of the guide holder 20, and is removed (see FIG. 3).

If the cork stopper C cannot be removed from the bottle mouth M for some reason only with the above-described structure, the guide holder 20 rises too much due to the rotation of the drill 30, and finally the inside of the case is destroyed. There is a risk. Therefore, in this embodiment, in order to prevent the guide holder 20 from rising too much, the emergency switch 53 is provided above the guide holder 20 as shown in FIGS. 4, 6C and 8.

The switch 53 is composed of a fixed contact 53 a fixedly provided above the guide holder 20 and a movable contact 53 b contacting the fixed contact 53 a. The movable contact 53 b is provided below the drill bearing 35. The arm 56 is supported by an arm 56 extending upward, and the arm 56 is biased downward by a winding spring 62. Therefore, the emergency switch 53 is normally in the ON state, and when the guide holder 20 rises too much, the upper wall 27 of the guide cylinder pushes up the arm 56 and disconnects both the contacts 53a and 53b. Then, the switch 53 is turned off, the motor 41 stops driving, and the guide holder 20 does not rise any more. At this time, when the power switch 52 is put in the reverse rotation position, the emergency switch 53 is disconnected from the power circuit (see FIG. 7), the guide holder 20 is lowered by the reverse rotation of the drill 30, and the emergency switch 53 is normally lowered by this lowering. Return to the ON state.
