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 beer container with a novel device for generating gas bubbles.

[Conventional technology]

In general, beer poured from a large capacity barrel such as 25 or 10 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 cannot be effective unless the beer is transferred from the container to a jug 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 that the invention attempts to solve]

The problem that this invention aims to solve is that even when drinking beer as is, such as canned beer, without pouring it into a bottle or pouring it into a container, the problem is that the carbon dioxide pressure does not increase without using any means to transfer the beer to another place. To provide a beer container having a device that generates soft and delicious fine foam like beer poured into a glass.

[Means for solving problems]

A means for solving this problem in the present invention is to provide a beer container having a foam generating device characterized in that one end of a vibrating piece is fixed to the bottom.

This vibrating piece is generally a long, thin plate made of an elastic material such as metal or plastic, and can be vibrated by flicking its free end with a fingertip, and its fixed Any material may be used as long as it can transmit vibrations from the bottom plate to the bottom plate.

To fix one end of this vibrating piece to the bottom, you can use any method such as gluing or fusing it with adhesive or solder, or caulking it in the same way as when attaching a pull tab to a can lid. good.

It is preferable that the bubble generating device is installed inside a recess generally provided at the bottom of the container so that stability is not impaired even when the container is placed on a table or the like.

[Effect]

In this invention, when the free end of the vibrating piece is vibrated by flicking it with a fingertip, the vibration is transmitted to the bottom plate through the fixed part, and as a result, the vaporization of carbon dioxide dissolved in the beer is promoted by the following effect. , it is estimated that fine bubbles are generated.

First, when the wall surface at the bottom of the fixed part of the vibrating piece vibrates and momentarily bulges outward, a depressurized part or gap is created between the container and the beer, and carbon dioxide is vaporized in the depressurized part or gap. to produce fine bubbles. This effect is evidenced by the generation of bubbles at the locations where the plastic pieces or the like come into contact or from the connections of the vibrating pieces.

Next, the vibration propagates from the fixed part of the vibrating piece to the surrounding area through the wall of the container, and when the surrounding area vibrates and momentarily swells outward, the connection between the container and the beer A reduced pressure section or void is created in between, and carbon dioxide is vaporized in the reduced pressure section or void, producing fine bubbles. This kind of effect is
This is confirmed by the fact that bubbles are generated not only from the fixed part of the vibrating element on the bottom plate, but also from the parts along the concentric circles thereof.

The vibrations also propagate through the beer liquid as compression waves, and carbon dioxide evaporates in the coarse portions, producing fine bubbles. This kind of action occurs not only at the fixed part of the vibrating element and its surroundings, but also at the
This is evidenced by the generation of foam throughout the beer.

In addition, the above phenomena and are strongly manifested in repellent plastic containers, and the above phenomena are strongly manifested in metal cans, where the elastic vibration continues for a relatively long time. This is considered to be supported by the following.

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.

〔Example〕

1 and 2 are a perspective view and a partial sectional view of the bottom of one embodiment of the beer container according to the present invention.

In these figures, 1 is a container, 2 is a bubble generator, 3 is a side wall, 4 is a bottom, 5 is a vibrating piece, 6 is a fixed part, and 7 is a free end.

In this embodiment, as shown in FIG.
The free end 7 of the vibrating element 5 is pulled downward and released to cause the vibrating element 5 to vibrate, and the vibration is transmitted to the bottom plate through the fixed part 6.

In this embodiment, the vibrating piece is fixed by crimping it onto a protrusion provided on a part of the bottom plate, in the same way as when a pull tab is attached to a can lid, as shown in Figure 2. There is.

In this example, when the vibrating piece is vibrated,
Foam is generated throughout the beer, centered at the bottom.

〔Effect of the invention〕

Since the beer container according to the present invention has the above-described structure, it is possible to produce soft beer like beer poured into a glass using carbon dioxide gas pressure without using any special means to transfer the beer. It can generate delicious fine carbon dioxide bubbles.
