Description

[Detailed description of the invention] [Industrial application field] This invention promotes the vaporization of carbon dioxide dissolved in the beer and deposits a fine, creamy carbonate on the top surface of beer in containers such as beer bottles and cans. The present invention relates to a novel beer foam generator for generating gas bubbles.

[Conventional technology]

In general, beer poured from large capacity barrels such as 25, 10, etc. into a beer bottle using carbon dioxide gas pressure is
It has very fine bubbles and is soft and delicious. These fine bubbles are produced by being placed in a large-capacity barrel under a carbon dioxide pressure of 2 to 3 kg/cm ² and then being poured into a tank under normal pressure.
It is thought to be produced by the rapid vaporization of carbon dioxide dissolved in beer.

On the other hand, in medium-capacity metal cans or plastic containers such as 2 or 3, the carbon dioxide pressure inside is much lower, so fine bubbles like this cannot be created under normal conditions, so if you pour from such a container, However, many inventions and ideas have been made to create fine bubbles.

The idea underlying these inventions and ideas is that, as a means to promote the vaporization of carbon dioxide dissolved in beer, shearing is mainly applied to the beer liquid by methods such as making the flow of beer into a trickle. A method of applying a velocity gradient, a method of applying vibration to the surface of the poured beer by hitting it with a trickle of beer, and a method of creating fine bubbles using the fine bubbles formed by the trickle of beer as the core. A method of forming a layer of air to reduce the entrainment of mainstream air in the beer (Special application)
54-151648, etc.), and a method in which the inner diameter and length of the air introduction pipe are set to appropriate dimensions to cause vibration in the flow of beer being poured out (Japanese Patent Application No. 55-94380, etc.).

However, such a method could not be effective unless the beer was transferred from the container to a mug or the like.

On the other hand, there are many products such as canned beer that can be drunk as is without being poured or poured. Generally, fine creamy foam is not produced when these containers are left open.

Furthermore, it has been known that tapping the bottles immediately after filling them with beer at a factory or the like promotes the vaporization of dissolved carbon dioxide.

However, even after opening a container such as a can containing beer and then hitting the container with a stick or the like, fine creamy foam was not generated from the beer inside the container.

[Problem to be solved by the invention] The problem to be solved by the invention is that even if you drink canned beer as it is without pouring it into a bottle or pouring it into a container, the problem is that it is difficult to drink the beer as it is without pouring it into a container. To provide a simple device capable of generating soft, delicious, and fine foam like beer poured into a beer bottle using carbon dioxide gas pressure without using any means.

[Means for solving problems]

The means for solving this problem in the present invention consists of an elastic body that has a fitting part at one end that fits into the rolled part of the beer container, and the fitting part is fitted into the rolled part. In this case, an extremely simple beer foam generator is used, which is characterized in that the elastic body is approximately parallel to and can come into contact with the side wall of the beer container.

The fitting portion that fits into the wrapper of the beer container generally includes one or more hooks that wrap around the wrapper, and
Most of them consist of one or more tongue-shaped parts that abut against the edge of the wrapper, but any elastic body can be fixed to the wrapper in a state that is approximately parallel to the side wall of the beer container and can come into contact with it. For example, it may have any structure.

In addition, the elastic body is generally a long and thin plate made of an elastic substance such as metal or plastic, but after it is fitted into the wrapper of a beer container, its free end can be held at the tip of a fingertip. Any type of material may be used as long as the elastic body can be brought into contact with the side wall of the beer container by bending it outward and separating it.

Note that it is preferable that the fitting part and the elastic body are made of the same material.

Furthermore, by providing a protrusion on the free end of the elastic body so that the protrusion strongly hits the side wall of the beer container when the elastic body is flicked, the foam generation effect can be improved.

[Effect]

In the present invention, when the free end of the elastic body is bent outward with a fingertip or the like and released, the elastic body hits the side wall of the beer container due to the reaction and gives a minute vibration to the side wall.As a result, the following occurs. It is presumed that this action promotes the vaporization of carbon dioxide dissolved in the beer, producing fine foam.

First, when the side wall of the beer container vibrates and momentarily bulges outward, a pressure-reduced area or gap is created between the container and the beer, and carbon dioxide is vaporized in the pressure-reduced area or gap, creating fine bubbles. generate.
This effect is supported by the fact that bubbles are generated from the area where the elastic body hits.

Next, the vibrations propagate from the point where the elastic body hits, through the wall of the container, to the surrounding area,
When the surrounding area vibrates and momentarily swells outward, a reduced pressure area or gap is created between the container and the beer, and carbon dioxide evaporates in that reduced pressure area or gap, producing fine bubbles. do. This effect is evidenced by the fact that bubbles are generated not only where the elastic body hits, but also from the entire side wall and bottom plate.

The vibrations also propagate through the beer liquid as compression waves, and carbon dioxide evaporates in the coarse portions, producing fine bubbles. This effect is supported by the fact that foam is generated not only from the walls of the container but also from the entire beer.

Furthermore, when a container containing beer is struck with a heavy object such as a stick, such minute vibrations are hardly generated, or even if they are generated, they quickly attenuate.
Because the entire container containing beer vibrates,
It is considered that fine bubbles are not generated.

When the foam generator shown in Figure 1 is attached to the rim of a beer can as shown in Figure 2, and the upper end of the elastic body is flicked outward with a fingertip, a minute vibration is generated on the side wall of the beer can. The vibrations are transmitted to various places, creating fine bubbles in the beer inside.

Moreover, when the foam generator shown in FIG. 2 is attached and used in the same manner, it is possible to generate fine foam in beer even more effectively.

[Effect of idea]

Since the beer foam generating device according to the present invention has the above-described structure, by using this device, beer can be foamed by carbon dioxide gas pressure without using any means to transfer the beer to another place. It can generate soft, delicious, fine-grained carbon dioxide bubbles, just like beer poured into a glass of beer.
