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 bubble 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 hitting the container with a stick or the like, the beer inside the container did not produce fine creamy foam.

[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. The objective is to provide a device that generates soft, delicious, and fine-grained foam, like beer poured into a glass of beer.

[Means for solving problems]

The means for solving this problem in the present invention consists of a fitting part that fits into the bottom of the beer container, an elastic plate extending inward from the fitting part, and a head part provided at the tip of the fitting part. The present invention provides a foam generating tool.

The foam generator according to the present invention has one end of an elastic plate fixed to the bottom of a beer container by a fitting part that fits into a winding part on the bottom, and a head provided on the free end of the elastic plate.
It is characterized by the fact that when you pull the head downwards with your fingertips and release it, the head hits the bottom of the beer container, giving a minute vibration to the bottom of the beer container.

Generally, it is preferable that this fitting part can be fitted in a detachable manner, and in order to prevent it from falling off easily, it is preferable that this fitting part should be fitted into the wrap-up part at the bottom of the beer container, but one end of the elastic plate It may have any structure as long as it can be fixed to the bottom of the beer container.

Even though this foam generator is removable, it is generally attached to the inside of the recess provided at the bottom of the container, so that it does not impair stability even when the container is placed on a table or the like. It is preferable to do so.

[Effect]

In this invention, the head of the elastic plate is applied to the bottom plate, and as a result of applying local minute vibrations to the bottom plate, the following effects promote the vaporization of carbon dioxide dissolved in beer and generate fine bubbles. It is estimated that

First, when the bottom surface where the head provided at the tip of the elastic plate hits vibrates and momentarily bulges outward, a pressure-reducing area or gap is created between the bottom surface and the beer, and the pressure-reducing area Or carbon dioxide evaporates into the voids, producing fine bubbles. This effect is supported by the fact that bubbles are generated from the bottom surface where the head provided at the tip of the elastic plate hits.

In addition, when the vibration of the elastic plate is transmitted to the wrapping part through the fitting part, and the wrapping part vibrates and momentarily bulges outward, a depressurized part or a gap is created between the bottom surface and the beer. Carbon dioxide vaporizes in the reduced pressure section or void, producing fine bubbles. This effect is supported by the fact that bubbles are generated from the bottom surface when the rolled part is tapped.

Next, those vibrations propagate through the wall of the container from the place where the head hits it or the wrapping part, and the surrounding area vibrates and momentarily swells outward. A vacuum zone or gap is created between the container and the beer, and carbon dioxide is vaporized in the vacuum zone or gap, producing fine bubbles. This effect is supported by the fact that bubbles are generated not only where the head hits, but also along concentric circles on the bottom surface.

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 in and around the area where the head hits, but also from the entire beer.

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

Note that when hitting the side wall of a container containing beer with a heavy object such as a stick, such minute vibrations are hardly generated, or even if they occur, they are quickly attenuated and the container containing beer is struck. It is thought that fine bubbles are not generated because the whole body vibrates.

In these figures, 1 is a fitting part, 2 is an elastic plate, 3 is a head, 4 is a fitting cylinder, 5 is a slit, 6 is a hook, 7 is a tongue-like part, and 8 is a free end.

In the first embodiment, the fitting part 1 consists of a ring-shaped fitting tube 4 that fits into the bottom of the beer container. A slit 5 is provided at the top of 4.

In three-beam cans, the diameter of the rolled part at the bottom is generally larger than the diameter of the body, so unless a slit is provided in the part that fits into the body, which has a smaller diameter than the rolled part, the fitting will not be possible. becomes difficult to do.

In the second embodiment, the fitting part 1 fits into a three-piece can, and includes a hook 6 that wraps around the outside of the rolled part and a tongue-like part 7 that abuts against the upper edge of the rolled part. It is designed to be fixed to the winding part.

In these embodiments, when the beer foam generator according to the present invention is fitted into a beer container and then the free end 8 is pulled down and released with a fingertip, the head 3 hits the bottom plate of the beer container, causing minute vibrations. As a result, fine bubbles are generated from the bottom of the beer.

[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 and delicious fine carbon dioxide bubbles, just like beer poured into a glass.
