Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a straw used for drinking soft drinks and the like.

(Conventional technology) Straws used for drinking soft drinks, etc.
As shown in FIG. 10, it is composed of a pipe made of synthetic resin or the like. When using this, one end is inserted into a soft drink, etc., and the other end is sucked.

(Problems to be Solved by the Invention) The above-mentioned conventional drinking straws can only be used for sucking up beverages, and are not easily changed during use. Also, if you want to stir the drink, you need to be able to move the straw itself.

The purpose of the present invention is to provide a straw that allows the user to enjoy sucking a beverage or stirring the beverage by utilizing the flowing force of the beverage when sucked up through the straw.

(Means for Solving the Problem) The drinking straw of the present invention has a driving body rotatably inserted into a pipe-shaped main body, and has blades inclined with respect to its axis, and both ends of the driving body are rotatably inserted into a pipe-shaped main body. each is supported by a bearing provided in the main body, one end of the driving body projects outside the main body, and a rotating body is attached to the part of the driving body that projects from the main body so as to be rotatable together with the driving body, A feature is that each bearing is provided with a liquid passage portion that allows liquid to pass in the axial direction of the main body.

(Function) In the straw of the present invention, the end of the protruding driving body is inserted into a soft drink, and the drink is sucked from the other end. When the beverage flows inside the main body, the driving body is rotated by the force, and the rotating body is rotated, and the rotation stirs the beverage or enjoys the movement of the rotating body that protrudes from the beverage.

(Example) Examples of the straw of the present invention will be described with reference to FIGS. 1 to 3.

In the figure, 1 is a pipe-shaped main body made of synthetic resin, etc., 2 is a drive body rotatably inserted into the main body 1, and the wings are constructed by spirally twisting a band-shaped synthetic resin. Support shafts 3a and 3b at both ends
is installed protrudingly. Reference numeral 4a denotes a bearing fixed to the main body 1, and a support shaft 3a having a needle-like tip is inserted into a shaft hole 5a provided in the center with one end closed. 6a is a liquid passage portion provided in the bearing 4a. The bearing 4a can be fixed to the main body 1 by any method such as friction between the two, thermal welding, or adhesive bonding.

Reference numeral 4b denotes a bearing provided at the end of the main body 1, and the end of the main body 1 is inserted into the cylindrical portion 7 provided around the bearing.
The support shaft 3b is inserted into the shaft hole 5b, and the drive body 2 is rotatably supported by bearings 4a and 4b.

Reference numeral 8 denotes a rotary body which is rotatably attached to the support shaft 3b protruding from the bearing 4b at a slight distance from the bearing 4b, and from the mounting portion 9 into which the end of the support shaft 3b is inserted, the body 1 is It is configured with a plurality of swing rods 10 protruding along the outside. Reference numeral 11 denotes a decorative body fixed to the tip of each rocking rod 10. Since the rocking rod 10 is made of synthetic resin and is elastically deformable, the centrifugal force generated by the rotation of the drive body 2 causes each rocking rod 1 to
0, the decorative body 11 swings. The swinging rod 10 has a length that protrudes outside the container such as a straw when the straw is used, and the decorative body 11
uses a pair of hemispherical ones. However, the decorative body 11 may be made of any lightweight material, such as one shaped like an animal, a plant, or any other shape.

In the above configuration, when the main body 1 is inserted into a soft drink or other beverage with its bearing 4b side and the drink is sucked from the upper end of the main body 1, the beverage rises inside the main body 1 from the liquid passage part 6b of the bearing 4b. Since the beverage passes through the liquid passage portion 6a of the bearing 4a, the driving body 2 is rotated by the force of the flowing beverage.

Therefore, the swing rod 10 of the rotating body 8 attached to the support shaft 3b swings in the radial direction of the main body 1 by centrifugal force while rotating, and swings the decorative body 11. The rod 10 stirs the beverage by swinging, and the decorative body 11 pleases the eyes of the user of the straw.

When the main body 1 sucks up the beverage in the cup, etc., the driving body 2 moves toward the bearing 4a due to the flow of the beverage, so as shown in FIG.
The end of a is sharpened into a needle shape, and the tip is attached to the bearing 4a.
If it is supported by the top wall of the shaft hole 5a, the frictional force between the support shaft 3a and the bearing 4a is reduced, and the drive body 2 can be easily rotated. but,
The shaft hole 5a may be formed arbitrarily, such as a through hole.

The driving body 2 can be easily formed by twisting a strip plate into a spiral shape, but as shown in FIGS. The driving body 2 can also be configured to be rotated by the beverage passing through the main body 1.

Further, as the rotating body 8, as shown in FIG. 6, a rotating body such as one in which stirring blades 14 slightly inclined with respect to the axis of the main body 1 are fixed to a mounting body 9 attached to the support shaft 3b is used. It is possible to use the rotating body 8 of any configuration depending on the purpose of use of the rotating body 8. The rotating body 8 in FIG. 6 rotates in the beverage as the beverage is sucked and can stir it more thoroughly, so if it is used to suck a beverage that is suitable for drinking while stirring. , eliminating the need for stirring.

In FIG. 7, instead of the swing rod 10 in FIG. 1, a pipe 15 is arranged on the outside of the main body 1, and a decorative body 11 is attached to the upper end of the pipe 15.
1. Enjoy the movement.

Therefore, by appropriately selecting the configuration of the rotating body 8, it is possible to stir the beverage and enjoy its movement, or to do either one of these.

In FIG. 8, a small hole 16 is provided in the main body 1 at the end on the bearing 4b side. When used with the small hole 16 out of the drink, air is sucked into the main body 1 through the small hole 16, and the drink is made into a mist by the air, which can be drunk. If the beverage is a soda or the like, it can be made foamy.

Although the bearing 4a is inserted into the main body 1 in FIG. 1, as shown in FIG.
Insert each end of a and 1b, and tighten the main body 1 with the bearing 4a.
a and 1b, and also connect the bearing 4a to them.
can also be attached.

(Effects of the invention) As described above, when the straw of the invention sucks a beverage, the flowing force of the beverage rotates the driving body in the main body to rotate the rotary body.
By appropriately selecting the configuration of the rotating body, it is possible to drink the beverage while stirring it with the rotating body, and/or to drink the beverage while enjoying watching the movement of the rotating body.
