Regarding the natural-fall type dispensing device for dispensing beverages in small quantities into a cup or sip, more specifically, it is designed to naturally generate a very pleasant sound when dispensing the beverage, and also to prevent This invention relates to a beverage dispensing tool which allows the dispensing tool to be used as a whistle.

[Conventional technology]

BACKGROUND ART Various structures have been proposed for dispensing tools for dispensing a drink, such as beer, from a container into a cup, cup, etc., and some of them have been put into practical use.

However, all of these dispensing tools have problems, such as how to dispense the beer in the container without damaging the original characteristics of the beer, or how to prevent a large amount of beer from being dispensed at once. And,
Alternatively, the structure was merely proposed to solve various problems or drawbacks that may occur during pouring, such as preventing bubbles from remaining in the pouring tool. As described above, conventional pouring tools have not been designed to have any other functions in addition to the function of effectively pouring out beverages.

The inventors of the present invention have further researched a dispensing tool that has the above-mentioned effective dispensing function, and have not only achieved the original function of a dispensing tool that can perform extremely effective dispensing of beverages. Furthermore, as a result of conducting research on a dispensing device that would give users a greater desire to drink and drink more quickly, as well as product value, etc., they discovered that when dispensing a beverage, the air flow introduced into the air introduction pipe generates sound. Developed a pouring tool and applied for a special patent application in 1982.
The application was filed as No. 204540 (Special Publication No. 62-7063).

[Problem that the invention attempts to solve]

The present inventors have proposed a dispensing tool that generates sound by the air flow taken in from the air introduction pipe.
As a result of further intensive research, they discovered that by installing a sound-generating mechanism at the tip of the air introduction tube, a low-pitched sound can be generated, making it audible to the user's ears without reducing the volume.

The pouring tool according to the present invention generates sound by the air flow sucked in from the air introduction pipe when pouring beer, etc., and its sound generating mechanism is as follows:
When the inhaled air passes through a small hole, it generates turbulence (vortex) in the airflow behind the small hole, vibrates, and the vibration resonates with the vibration of the air (air column) in the air introduction tube. The sound is generated by

Such a sound generating mechanism generates a sound that resonates with the vibrations of the air (air column) in the air introduction pipe, so if the length of the pipe is short, it will produce a high pitched sound, and if it is long, it will produce a low pitched sound.

On the other hand, the dispensing tool cannot be made very large and there is a certain limit to the length of the air introduction tube, so if a small hole is provided in the center of the air introduction tube, the air column in the air introduction tube is divided at the small hole,
A high pitched sound is generated.

Therefore, in order to make the sound even lower and more pleasant without increasing the length of the air introduction tube, it is necessary to provide a small hole at the tip of the air introduction tube to lengthen the air column. For this reason, if a small hole is provided at the end of the air introduction tube where it is attached to the container, the small hole will come into contact with the beverage, making it difficult to generate airflow turbulence (vortex). It must be installed on the tip side.

The inventors of the present invention have developed a device that generates sound by the air flow introduced into the air introduction tube when dispensing a beverage, by configuring a sounding mechanism at the tip of the air introduction tube. They discovered that the sound could reach the user's ears as is without reducing the volume, and arrived at the present invention.

[Means for solving problems]

The present invention provides a dispensing tool having a dispensing hole and an air introduction pipe, in which the inner diameter of the hole in the partition wall provided at the tip of the air introduction pipe is made smaller than the inner diameter of the air introduction pipe, thereby creating a sound mechanism. The present invention relates to a beverage dispensing tool characterized by the following configuration.

[Effect]

All you have to do is grasp the container as usual, tilt it, and pour out the beverage inside the container. During this pouring, air is compressed through the small holes of the sound cylinder, flows into the sound cylinder and is expanded, is further compressed and flows into the air introduction pipe, and is introduced into the container. In this case, the air squeezed by the small holes at the sound tube is
A whirlpool is created in the air introduction tube, which is resonated by a long resonance region, and the wavelength becomes low, producing a sound with the same tone as the chirping of a small bird. Therefore, the user pours the beverage while listening to this, giving the user an extremely refreshing auditory sensation.

〔Example〕

The embodiments of the present invention shown in the drawings will be described below, but the present invention is not limited thereto.

The pouring tool 1 is composed of two parts: a mounting tube 2 and a pouring nozzle 3. As can be seen from the cross-sectional view of FIG. 1, the mounting tube 2 has its tip side (the right end side in FIG. 1) bent at a slight angle.
It is made for easy pouring. A collar 5 is integrally provided on the left end side of the mounting tube 2 in FIG. A mounting cylinder 6 is provided continuously to the collar 5. A press-fitting protrusion 7 is formed on the outer peripheral surface of the mounting cylinder 6. The press-fitting protrusion 7 is attached to a container (not shown in the drawings) in a fluid-tight and removable manner by a press-fitting means.

At the bending part of the mounting tube 2, a semicircular baffle plate 8 extends from the inner peripheral surface of the top of the mounting tube 2 to a passage 10 of the pouring tube 9.
It protrudes inside. The baffle plate 8 has an air pocket 1 at the bent part of the main pouring hole 10 when pouring out the beverage.
1 and 12. These air pockets 11 and 12 serve as a flow path for beverages, such as beer and foam, remaining in the flow path of the pouring tool 1 to return to the container when pouring out the beverage is stopped and the container is stood up. Reduce the viscous resistance received from the wall,
This has the effect of making it easier to return, and also prevents those residues from being accidentally blown out due to the carbon dioxide pressure inside the container.
The distal end side (the right end side in FIG. 1) of the spout tube 9 is formed thin so that a spout nozzle 3, which will be described later, can be inserted smoothly. A protrusion 14 is integrally formed on the lower side of the pouring tube 9. The tip of a presser piece 15 is positioned opposite the protrusion 14, and an insertion space 16 is formed between the presser piece 15 and the protrusion 14. The left end of the air introduction pipe 13 in FIG. 1 projects outward from the mounting tube 6. By projecting the end portion 13a of the air introduction tube 13 in this manner, it can be easily held in the mouth and used as a whistle. Further, a sound cylinder 17 is detachably attached to the right end of the air introduction pipe 13 in FIG. The sound cylinder 17 has one end open and the other end closed. Then, the opening side is the air introduction pipe 1 mentioned above.
It is installed on 3. The sound tube 17 is provided with a cover tube 19 located on the partition wall 18 side, and the cover tube 19 has an opening formed in a tapered surface 20. A small hole 21 is formed in the partition wall 18 .
In the case of this example, the inner diameter "D" of the air introduction pipe 13 is 7~
The inner diameter "d" of the small hole 21 of the sound tube 17 is set to be 2.7 to 3.3 mm.

The dispensing device according to the present invention generates sound by the air flow sucked in from the air introduction pipe when pouring beer, etc., and the sound generation mechanism is such that the sucked air passes through the small holes. When passing through, the airflow generates turbulence (vortices) behind the small hole, vibrates, and the vibrations resonate with the vibrations of the air (air column) in the air introduction tube, producing sound. be. Such a sound generation mechanism generates a sound that resonates with the vibration of the air (air column) in the air introduction tube, so if the length of the air introduction tube is short, it will produce a high pitched sound, and if it is long, it will produce a low pitched sound. On the other hand, since the dispensing tool cannot be made very large and there is a certain limit to the length of the air introduction tube, if a small hole is provided in the center of the air introduction tube,
The air column in the air inlet tube is split at the small hole, producing a high-pitched sound. In order to make the sound even lower and more pleasant without increasing the length of the air introduction tube, it is necessary to provide a small hole at the tip of the air introduction tube to lengthen the air column. For this reason, if a small hole is provided at the end of the air introduction tube on the side where it is attached to the container,
Since the small hole comes into contact with the beverage and makes it difficult to generate airflow turbulence (vortex), the small hole must be provided at the tip of the air introduction tube as in the present invention.

A semicircular arc groove 22 is provided at the top of the pouring nozzle 3. This semi-circular arc groove 22 is connected to the pouring nozzle 3.
When attached to the opening of the extraction cylinder 9, it is arranged along the outer peripheral surface of the sound cylinder 17. The pouring nozzle 3 is the first
In the figure, the left end side is formed as a thin wall portion 23.
This thin wall portion 23 is smoothly attached to a thin wall opening 24 formed on the opening side of the pouring cylinder 9. A substream chamber 25 is integrally provided in the lower part of the pouring nozzle 3, and a substream outlet hole 26 is provided at the right end of the secondary stream chamber 25 in FIG. The upper surface of the side flow chamber 25 is open and communicated with the inside of the spout nozzle 3.
The left end portion of the side flow chamber 25 in FIG. 1 is cut away at the thin wall portion 23 thereof. This notch 27 forms an insertion wall 28 at the left end of the side flow chamber 25 in FIG. This insertion wall 2
8 is inserted into the insertion space 16. The spout of the spout nozzle 3 is formed on the tapered surface 29.

To use the pouring tool according to the present invention, the mounting tube 6 is press-fitted into the mounting opening of a container (not shown) and fixed. Therefore, the user can simply grip and tilt the container as usual and pour out the beverage inside the container. During this pouring, the air present in the cover tube 19 is compressed through the small hole 21 of the sound tube 17, flows into the sound tube 17, is expanded, and is further compressed into the air introduction tube 13. and is introduced into the container. As mentioned above, at the sound tube 17, the air squeezed by the small hole 21 causes a swirl in the air introduction tube 13, and this is resonated by a long resonance region and becomes a low wavelength "piyo-piyo". ”, a sound with the same timbre as a small bird chirping is produced. Therefore, the user pours the beverage while listening to this, giving the user an extremely refreshing auditory sensation.

Due to the air introduction described above, the beverage in the container is poured out from the main pouring hole 10 through the pouring nozzle 3, but in this case, the beverage that has entered the side flow chamber 25 is also poured out through the secondary pouring hole 26. It is poured out at the same time. A relatively large amount of beverage is poured out from the above-mentioned pouring nozzle 3,
Therefore, the poured beverage entrains air particles in the cup or bottle, resulting in the formation of large bubbles. However, sidestream chamber 2
5 and is poured out from the sub-pouring hole 26, fine vibrations are applied to the liquid level of the beverage already stored in the cup or jug.
Therefore, the carbon dioxide gas dissolved in the drink is stimulated by the carbon dioxide gas to form countless fine bubbles that cover the liquid surface of the drink. This is stopped only at the initial stage of brewing, and the generation of large bubbles is effectively prevented.

Furthermore, when pouring out the beverage is stopped and the container is stood up, the air remaining in the flow path of the pouring tool 1 is caused by the air in the air pockets 11 and 12 formed on both sides of the baffle plate 14. To reduce the viscosity resistance that beer and foam receive from the channel wall when returning to the container.
Therefore, the remaining beverages are more easily returned to the container and are not inadvertently squirted out due to the pressure of carbon dioxide gas in the container.

In addition, once all the beverages in the container have been poured, the pouring tool 1 is removed from the container and the pouring tool 1 is removed from the container.
You can use it as a whistle. All you have to do is grasp the mounting tube 6, put the end 13a of the air introduction tube 13 in your mouth, and blow in or blow air into it. Now, to explain the case where air is blown into the air introduction pipe 13, the air blown into the air introduction pipe 13 is compressed and blown out from the sound tube 17 through the small holes 21. This compression causes resonance in the sound tube 17, which produces a tone similar to the "beep" sound produced when whistling. In this way, the pouring tool after pouring out the beverage can be used as a whistle, which has the advantage of further expanding the scope of use of the pouring tool and further increasing its commercial value.

[Effect of idea]

As explained in detail above, according to the dispensing tool of the present invention, not only can drinks be dispensed under the best conditions, but also the air inlet pipe and the sound that can be detachably attached to the dispensing tool can be used. Since an extremely simple sounding mechanism consisting of a sound cylinder is provided, a refreshing sound can be generated from the sound cylinder when pouring a beverage. Further, since the dispensing tool of the present invention has a sounding mechanism near the tip of the air introduction tube, the generated sound can reach the user's ear as it is without reducing the volume. Therefore,
Since the user can pour while listening to this sound, the user's auditory sense is further enhanced and the drinking effect is improved.
