Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a corkscrew for removing corks fitted into the mouths of bottles containing wine or other beverages.

(Prior Art) Conventionally, corkscrews have basically had a shape in which a spiral nail is fixed to a handle, and various shapes have been proposed in consideration of ease of use. The same applies to the spiral nail of the puller. However, spiral nails are usually made of a different material from other parts, such as the handle of a corkscrew, in consideration of strength and other factors.

In addition, unless the spiral nail is securely fixed to the grip handle, the spiral nail cannot be reliably screwed into the cork. Therefore, the spiral nail must be securely fixed to the grip handle. However, in the past, the straight part of the rear end of the spiral nail was inserted into the grip handle and the tip was bent into an L shape, or a space was provided at an appropriate position such as the center of the handle, and the rear end of the spiral nail was inserted as shown in Figure 3. The grip handle is divided into two halves with the end bent in two directions, and a screw is cut at the rear end of the spiral nail and screwed into the handle, or the upper end of the spiral nail is made thicker and the grip handle is sealed. After the nail is inserted into the handle, a locking rod is inserted into the grip handle and is locked by fitting into a hole in the thick upper end of the spiral nail.

(Problem that the invention attempts to solve) However, simply inserting a spiral nail into the grip handle,
Although the structure is simple when the tip is bent into an L-shape, it has the disadvantage of being unsightly.

In addition, in the configuration in which the rear end of the spiral nail is bent in two directions as shown in Figure 3, there are many steps to manufacture the spiral nail, and the screw is sealed in the grip handle, making it difficult to use a corkscrew with a complicated structure. may not be applicable.

If a screw is cut at the rear end of the spiral nail and screwed into the grip handle, there is a possibility that the spiral nail 1 may come off. Furthermore, the upper end of the spiral nail is made thicker, and after the nail is inserted into the handle, a locking stud is inserted into the handle and inserted into a hole in the thicker part of the upper end of the spiral nail to lock the nail. However, it has the disadvantage that it requires many steps and cannot be manufactured at a low cost, and also has the disadvantage that the locking studs leave marks on the side of the grip handle. Therefore, the object of the present invention is to provide a corkscrew with a simple structure in which the spiral nail does not wobble from side to side or back and forth during the corkscrew operation, and the spiral nail is securely fixed to the handle.

(Means for Solving the Problems) The present invention has two or more consecutive spirals of the fixing part 2 of the spiral nail 1, by sequentially shortening the pitch width of the spirals or making them irregularly spaced. The fixing portions 2 have different pitch widths and are sealed and fixed inside the grip handle 3 during molding.

(Function) In the present invention, since the fixing part 2 of the spiral nail 1 is fixed inside the grip handle 3, the fixing part 2 is not exposed to the outside of the grip handle 3 and does not hurt the palm etc., and furthermore, the spiral nail Since the spiral fixing part 2 of 1 is sealed and fixed inside the grip handle 3 during molding, the fixing part 2 is spiral-shaped, so the fixing part 2 can be securely fixed to the grip handle 3. The pitch widths of the spirals in part 2 were not made the same pitch width, but were made to have different pitch widths, such as by sequentially shortening the pitch widths in two or more consecutive spirals, or by making them irregularly spaced, so it is not fixed. Since the part 2 can be securely fixed so that it does not rotate within the grip handle 3, even if the degree of closeness between the fixed part 2 and the grip handle 3 weakens due to long-term use, the fixed part 2 can still be rotated within the grip handle 3. Since the fixing part 2 does not separate from the grip handle 3 and has two or more consecutive spirals, the fixing part 2 can be extremely securely fixed to the handle 3, and the spiral nail 1 can be easily turned during bottle opening work. In this case, the pitch width of the spiral of the fixed part 2 was not set to the same pitch width, but was made to a different pitch width to prevent the fixed part 2 from rotating in the same way as the spiral nail 1. 1, the spiral nail 1 does not separate from the grip handle 3 even when used for a long period of time, and the shape of the fixing part 2 is Since the pitch width of the spiral is gradually shortened or the pitch width is irregularly spaced, and the pitch width is simply changed, and the molding is performed without using any other materials, it can be easily mass-produced at a low cost. The fixing part 2 has the same thickness as the lower part and is not made thinner, so the lower fixing part 2 of the spiral nail 1
The strength of the spiral nail 1 does not change, and the spiral nail 1 does not break on the way.

Furthermore, in the present invention, the fixing portion 2 at the rear end of the spiral nail 1 is formed with different pitch widths, and
This fixing part 2 is enclosed and fixed inside the grip handle 3 during molding. Therefore, since the pitch width of the fixed part 2 is not constant, even if the handle 3 is rotated and the corkscrew operation is repeated after it is sealed and fixed in the handle 3, the fixed part 2 of the spiral nail 1 will not be fixed. It is difficult to get out of grip handle 3. In addition, since the helical center of the spiral nail 1 and the helical center of the fixing part 2 of the spiral nail 1 can be made the same, the long spiral nail 1
It is easy to obtain the center of rotation of the corkscrew when manufacturing corkscrews using Furthermore, the fixing part 2 is formed by pulling the upper part of the spiral when forming the spiral nail 1,
Alternatively, it can be produced by compressing it.
In addition to being able to reduce manufacturing costs, since the fixing part 2 is enclosed and fixed within the grip handle 3, the grip handle 3 can be beautifully finished.

(Example) The present invention will be described in detail below using an example based on the drawings.

A wire made of an appropriate material such as iron, metal, hard ceramic, etc. is formed into a spiral shape, and its tip is sharpened. The helical pitch width of the helical portion at the rear end is made gradually shorter, so that they are not spaced at equal intervals. Next, the part where the pitch width is not evenly spaced is fixed part 2.
During molding, it is sealed and fixed at a predetermined position within the grip handle 3, which is made of an appropriate material such as plastic or other synthetic resin or metal.

The embodiment shown in FIG. 2 is an example in which a long spiral nail 1 is used. A cylindrical body 4 formed below the grip handle 3 fixing the rear end of the spiral nail 1 is inserted into the guide tube 5 of the spiral nail 1 so as to be vertically movable. Therefore, when the grip handle 3 is turned and the spiral nail 1 is rotated and moved to the grip handle 3, the cylindrical body 4 formed at the bottom of the grip handle 3 is moved downward along the guide tube 5. Moving. According to this operation, the spiral nail 1 also descends while rotating downward, and screws into the cork stopper 7 inserted into the bottle 6.

Generally speaking, when the handle of a corkscrew that uses a long spiral nail is rotated, it is difficult to maintain the center of rotation of the spiral nail, which can easily damage the cork stopper, which is a bottle stopper, and cause the cork to break. It often falls inside the bottle. However, in the embodiment shown in FIG. 1 to ensure that the center of rotation does not shift.
The cork stopper can be easily pulled out without being damaged by vertically moving the spiral nail 1 without causing it to slacken in the middle.

(Effects of the invention) The present invention is constructed and operates as described above, and the fixing part at the rear end of the spiral nail fixed to the grip handle is formed with different pitch widths. Not only does it prevent the nail from slipping out of the handle, but it also allows the center of the spiral nail to be the same as the center of the spiral at the fixed part of the spiral nail, making it ideal for manufacturing corkscrews that use long spiral nails. It is. In addition, the fixing part can be manufactured by pulling or compressing the upper part of the spiral when forming the spiral nail, making mass production possible at low cost, and the fixing part is completely enclosed and fixed within the grip handle. Therefore, it has excellent effects such as making the grip handle neatly finished.
