Description

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

[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 created by pouring carbon dioxide dissolved in the beer into a beer bottle under normal pressure from a large-capacity barrel under a carbon dioxide pressure of 2 to 3 kg/ ^cm2 . It is thought to be produced by rapid vaporization.

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 ideas and inventions is to create a shear velocity gradient in the beer liquid, mainly by making the flow of beer a trickle, as a means of promoting the vaporization of carbon dioxide dissolved in the beer. A method of applying vibrations to the surface of the poured beer by hitting the surface of the beer with a trickle of beer.First, a layer of fine foam is created with the fine bubbles formed by the trickle of beer as the nucleus. JP-A-1983-1973 - Method for reducing air entrainment in the mainstream of beer by forming
No. 74487, etc., and a method in which the inner diameter and length of the air introduction pipe are set to appropriate dimensions to cause vibrations in the flow of beer being poured out (Japanese Patent Laid-Open No. 57-28797, etc.), etc. are used.

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 that can be drunk as is, such as canned beer, 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.

The present inventors discovered that in canned beer, etc., after opening,
An invention (Japanese Unexamined Patent Publication No. 61-40781) and several ideas (Utility Model Application Publication No. 61-38033, Completed Utility Model No. 61-38034 and Utility Model No. 61-35647).

[Problem that the invention attempts to solve]

However, Utility Model Application No. 61-38033, Utility Model Application No. 61
The beer foam generators disclosed in Japanese Utility Model Application No. 38034 and Japanese Utility Model Application Publication No. 61-35647 were not necessarily sufficient in terms of ease of manufacture, ease of installation, firmness of fixation, etc.

The problem to be solved by the present invention is to provide a beer foam generator that is easy to manufacture, easy to adhere to the container, firmly fixed to the container, and has a high foam generation effect. .

[Means for solving problems]

The means for solving this problem in the present invention consists of an annular fixing part that is housed in a concave bottom of a can or the like and whose outer shape is inscribed in the bottom surface, and an adhesive part formed on both the front and back surfaces of the fixing part. , comprising an elastic body extending from a part of the fixing part toward the center thereof, and a bottomed part housed within the outer shape of the fixing part and provided on both the front and back surfaces of the elastic body. It is a feature.

The fixing part is attached to the outside of the beer container using, for example, a hot melt adhesive, and since the center of the bottom of a beer can is generally recessed, it is preferable to attach it to the recessed part.

Although it is possible to manufacture the head separately from a metal piece or the like and attach it to the elastic plate, the whole head may be integrally molded from synthetic resin.

[Function] Since the beer foam generator according to the present invention has an outer shape that is inscribed in a circle, there is no need to consider directionality when handling it.

Since the fixing part, that is, the adhesive part, is annular, the adhesive surface is wide, and the adhesive is also attached to parts other than the base of the elastic body, where strong peeling force is exerted. As a result, this beer foam generator is strong. can be attached to.

Since the bottom striking part that strikes the bottom of the container is provided approximately at the center of the ring of the fixing part, beer foam can be effectively generated.

Since the adhesive part and the bottom part are provided on both the front and back sides, there is no need to consider the front and back sides when handling. Further, the foam generator according to the present invention is accommodated in the concave bottom of the beer can or other container to which it is attached, and does not protrude from the bottom, making it convenient for handling and storing the beer container.

〔Example〕

1 to 3 show a first embodiment of the present invention, and FIG. 4 shows a second embodiment.

As shown in the drawings, in the foam generator according to the first embodiment of the present invention, a ring-shaped fixing part 10 is attached to a beer container 1.
4 is attached to the bottom wall. This fixed part 1
0 is a flat plate with an annular planar shape, and as shown in FIG. 2, the front and back surfaces are protruding along the curvature of the bottom wall of the beer container 14.

A plurality of minute irregularities are formed on the front and back surfaces of the fixing portion 10, and these serve as surfaces to which an adhesive is applied.

An elastic plate 16 protrudes radially inward from a portion of the fixed portion 10. This elastic plate 16 has bottom striking parts 18 protruding from the front and back sides at the tip thereof, and is used for striking the bottom wall of the beer container 14.

It is preferable that the bottom of the bottom part 18 be sharp in order to generate bubbles, but if the tip is too sharp, the impact energy will be used to deform the capacitance, making it difficult to generate bubbles.

Further, in this embodiment, one bottom striking part 18 is provided at the tip of the elastic plate 16, but the appropriate number is 1 to 20, and the position thereof is also determined depending on the state of attachment to the beer container 12. It is preferable to arrange it approximately in the center of the bottom surface of the beer container 12. For this reason, the bottom striking portion 18 is provided approximately at the center of the ring of the fixed portion 10.

The beer foam generator of this embodiment configured as described above has a symmetrical shape between the front and back through the fixing part 10, so that there is no need to distinguish between the front and the back when it is attached to the beer container 14.

Moreover, by making the outer shape of the fixing part 10 into an annular shape having an outer shape inscribed in a circle such as a circle, handling is convenient when automating the assembly work of adhesively attaching it to the beer container 14.

In the foam generator of this embodiment, since the elastic plate 16 is disposed inside the fixing part 10, when it is attached to the beer container 14 as shown in FIG. It is safe and will not get caught on objects.

When in use, when the tip of the elastic plate 16 is separated from the bottom wall of the beer container 14, the elastic plate 16 is elastically deformed and stores strain energy. When the tip of the elastic plate 16 is suddenly released, the elastic plate 16 applies a striking force to the bottom wall of the beer container 14 due to the release of strain energy. This promotes the vaporization of carbon dioxide dissolved in the beer in the beer container 14 and generates fine foam.

In this embodiment, the fixing part 10 does not need to be in the form of a frame in which all parts are completely connected, and may be cut into a C-shape with a cutout or the like formed in a part thereof.

Next, in the second embodiment shown in FIG. 4, by providing an S-shaped slit 24 in a part of the fixing part 10, a pair of elastic plates 16 are shaped to integrally protrude inward from the fixing part 10. It's summery. Each of these elastic plates 16 is provided with a bottomed part 18 near its tip, and has the same function as the previous embodiment. The slit 24 has a wide width near the bottom part 18 so that the elastic plate 16 can be easily placed with a finger.

In each of the embodiments described above, the outer shape of the fixing part 10 is circular, but it goes without saying that other shapes other than circular can also be applied.

[Effect of idea]

Since the present invention has the above-described configuration, it is possible to obtain a beer foam generator that is easy to manufacture, easy to adhere to the container, firmly fixed to the container, and has a high foam generation effect. . Furthermore, since the foam generator does not protrude from the bottom of the beer can, it is convenient to handle and store.
