Description

[Detailed description of the invention] [Field of industrial application] This invention produces a fine, creamy carbon dioxide gas on the top surface of beer in containers such as beer bottles and cans by vaporizing carbon dioxide dissolved in the beer. This invention relates to a novel device for generating foam.

[Conventional technology]

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

On the other hand, in medium-capacity metal cans or plastic containers such as No. 2 or No. 3, the internal carbon dioxide pressure is considerably lower, so such fine bubbles are not formed under normal conditions. For this reason, even when poured from such a relatively low-pressure container into a tank,
A number of means have been proposed to enable the formation of fine bubbles.

These proposals include, for example, a method of creating a shear velocity gradient in the beer liquid by making the flow of beer trickle;
A method of applying vibration to the surface of the beer by hitting the surface of the poured beer with a trickle of beer. First, a layer of fine foam is formed with the fine bubbles created by the trickle of beer as the nucleus, and the beer (Japanese Patent Application No. 151648/1982 (Japanese Patent Publication No. 1904/1983), etc.) and the flow of beer that is poured out by adjusting the inner diameter and length of the air introduction pipe to appropriate dimensions. (Japanese Patent Application No. 55-94380 (Japanese Unexamined Patent Publication No. 57-28797), etc.), but these methods do not lose their effect unless the beer is transferred from the container to the brewer. It was something I could not demonstrate.

However, there are many products currently on the market, such as canned beer, that can be drunk as is without pouring the beer into a bottle or bottle, but these products generally have a fine, creamy consistency when the container is opened. No bubbles are generated.

Furthermore, it has been known that tapping the bottle immediately after filling it with beer promotes the vaporization of dissolved carbon dioxide. However, in the case of canned beer, even after opening the container and hitting the container with a stick, etc., the beer inside the container did not produce fine, creamy foam.

The applicant claims that when drinking canned beer, etc.,
After studying methods for forming fine bubbles on the surface, Japanese Patent Application No. 59-162171 (Japanese Unexamined Utility Model Publication No. 61-40781), Utility Model Application No. 59-121248 (Japanese Utility Model Application No. 61-38033), No. 59-121249 (Utility Model Publication No. 61-38034)
and No. 59-121250 (Japanese Utility Model Publication No. 61-35647) proposed a foam generator that is attached to the bottom of a beer container to impart vibration to the can and beer.

[Problem that the invention attempts to solve]

The present invention aims to improve the above-mentioned vibration-applying foam generator by providing an efficient foam generator that has good workability during installation and uses less material during manufacturing. .

[Means for solving problems]

The object is to provide a circular fixing part having a mounting surface having a convex surface with a curvature that substantially matches the concave surface of the outer bottom wall of the beer container according to the present invention, and an annular notch part surrounding the fixing part. The fixing part and the notch part have a part of their circumference,
interconnected by elastically deformable bridge parts,
Further, the beer foam generator is characterized in that a free end region of the notch part located at a circumferential position diametrically opposite to the bridge part is provided with a protrusion at least on the same side as the mounting surface. achieved by.

It is desirable that the foam generator has a vertically symmetrical shape as a whole.

Further, it is preferable that the mounting surface of the fixing part is formed of a rough surface or a plurality of ribs, particularly ribs arranged parallel to each other.

The present invention will be explained in more detail below based on the drawings.

One of the beer foam generators according to the present invention is shown in FIGS. 1 and 2. This foam generator is used while being fixed to the bottom of a beer container such as a can with an adhesive or the like.

The foam generator 1 includes a disk-shaped fixing part 2, an annular notch part 3 surrounding the fixing part 2 and concentric with the fixing part 2,
and a bridge section 4 made of an elastic material that connects both 2 and 3. With this structure, the fixing part 2 and the notch part 3 are movable in the vertical direction using the bridging part 4 as a fulcrum by elastic deformation of the bridging part 4 and the notch part 3 themselves. The free end area 3a of the notch part 3 diametrically opposed to the bridge part 4 has a tip on the side facing the bottom wall 6a of the beer container 6 when the foam generator 1 is attached to the bottom wall 6a. A protrusion 5 having a hemispherical shape is provided in a protruding manner. Preferably, each of these constituent members is integrally molded from synthetic resin.

A further feature is that at least one surface (mounting surface) 2a of the fixing part 2 on the side fixed to the bottom wall 6a of the beer container has a curvature that complements the concave surface of the bottom wall 6 of the beer container. It is composed of a convex surface, and the surface has many small irregularities2 over the entire surface.
b is provided to form a rough surface.

[Effect]

The operation of the foam generator 1 of the present invention having such a configuration will be explained next.

The foaming device 1 is fixed to the bottom wall 6a of the container at an appropriate point in the container manufacturing process or the beer filling process.As an example of the method, as shown in FIG. An appropriate amount of molten adhesive resin such as hot melt 8 is supplied to approximately the center of the bottom wall 6a of the beer containers 6 which are successively conveyed with the bottom wall 6a facing upward, and then the foam generator 1 of the present invention is added to the beer containers 6. The fixing part 3 is placed on the hot melt 8 so that the mounting surface 2a faces downward. As mentioned above, since the mounting surface 2a and the bottom wall 6a are formed with uneven surfaces that complement each other, the foam generator 1 can be attached to the bottom wall 6a without special care during supply. When pressed against the foam generator 1, the foam generator 1 naturally moves to the center of the bottom wall 6a and becomes stable. Moreover, since the bubble generator 1 has a circular shape as a whole, there is no need to consider directionality.

When the foam generator 1 is pressed from above by an appropriate means in this state, the hot melt 8 enters the space between the small irregularities 2b on the adhesive surface 2a, substantially reducing the adhesive area Since it is expanded, a strong fixing effect between both members 2 and 6 can be obtained.

Describing how to use this foam generator 1,
When a consumer drinks the beer that contains it,
After opening the container as usual, lift the free end area 3a of the knob 3 away from the bottom wall 6a,
Then release rapidly. As a result, the projection 5 provided in the free region 3a hits the bottom wall 6a of the can due to the elastic recovery force of the bridge portion 4, which causes the can wall to vibrate first, and then the beer itself to vibrate. propagates, the carbon dioxide gas in the liquid evaporates and becomes fine, fine-grained bubbles that rise to the liquid surface, forming a layer of creamy bubbles.

Due to the above-mentioned mechanism, even in canned beer under relatively low pressure, a layer of foam can be formed on the liquid surface, similar to when beer from a barrel is transferred to a brewer, giving the user a delicious taste. be able to.

(Embodiment) The foam generator shown in FIGS. 1 and 2 is a first embodiment of the present invention, and its details are as described above.

5 and 6 show a foam generator according to a second embodiment of the present invention. In this example, the foam generator 1 is placed on its center plane (X-X plane in FIG. 6).
It is vertically symmetrical. That is, the surface of the fixed part 3 is formed by ribs 7 that are parallel to both the upper and lower surfaces, and the upper edge of the ribs 7 is connected to the bottom wall 6a of the container 6.
The protrusion 5 of the free end region 3a of the notch portion 3 is also provided on both sides.

The advantage of this configuration is that in the process of fixing the foam generator, when feeding the foam generator 1 to the bottom wall 6a, there is no need to distinguish between the front and the back, so automation can be easily performed, and adhesives such as hot melt can be easily automated. The purpose is to enter between the ribs 7, flow along them, and spread over the entire mounting surface, thereby increasing the adhesive effect.

In addition to the above-mentioned shapes, the ribs forming this surface may have a lattice shape as shown in FIG.
There are concentric circular shapes as shown in the figure, radial shapes as shown in FIG. 9, etc.

Furthermore, in the third embodiment shown in FIGS. 10 and 11, a finger rest 10 is provided inside the free end area 3a of the knob 3 to facilitate pulling up the knob 3 with a finger during use. There is.

The fourth embodiment shown in FIG. 12 is a modification of the example shown in FIG. It is provided inside the inner diameter of. The advantage of this configuration is that in the above-mentioned fixing process, when the foam generator 1 is sequentially supplied while sliding the both sides of the notch part 3 on two guide rails (not shown), the protrusion This is because it is possible to prevent jamming from occurring when the 5 gets caught on a rail or the like.

[Effect of idea]

According to the present invention, the following effects occur.

(1) Since the overall shape is circular, there is no directionality, making it easier to automate the bonding process.

(2) Since the mounting surface is a convex surface with a curvature complementary to the shape of the bottom wall of the can, it is easy to align the two.

(3) Since the fixing part is provided at the center of the foam generator, the adhesive prepared in advance at the center of the bottom wall of the can can be brought into contact with the foam generator simply by aligning the center as described above, and the adhesive Process automation becomes easier.

(4) If the mounting surface of the fixing part is made of a rough surface, sufficient adhesive strength can be obtained even if there is some misalignment between the foam generator and the adhesive prepared at the center of the bottom wall of the can. It will be done.

(5) If the mounting surface is constituted by a rib, the above-mentioned centering operation can be performed more smoothly due to the curved surface formed by the upper end of the rib.

(6) During the bonding process, the adhesive spreads over the entire surface of the fixed part along the ribs, further increasing the bonding strength.

(7) If the foam generator is configured vertically symmetrically, there is no need to consider the front and back sides during bonding work, making automation easier.
