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.

(Prior Art) In general, beer poured from large capacity kegs such as 25 liters or 10 liters into beer bottles using carbon dioxide gas pressure has very fine foam 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 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 2L or 3L, the carbon dioxide pressure inside is much lower, so such fine bubbles are not formed under normal conditions. For this reason, a number of methods have been proposed for producing fine bubbles even when poured from such a relatively low-pressure container into a bottle.

These proposals include, for example, methods to create a shear velocity gradient in the beer liquid by making the flow of beer into a trickle, and methods to create vibrations on the surface of the beer by hitting the surface of the poured beer with a trickle of beer. Methods, such as ``Japanese Patent Application Laid-Open No. 1974-74487'', which forms a layer of fine bubbles with the fine bubbles formed by the trickle of beer as the core, and reduces the entrainment of air in the beer flow, and the inner diameter of the air introduction pipe. There are methods such as ``Japanese Unexamined Patent Publication No. 57-28797'' in which the flow of beer is caused to vibrate by adjusting the length and length appropriately, but these methods do not transfer the beer from the container to the brewer, etc. Until then, the effect could not be demonstrated.

However, there are many products currently on the market, such as canned beer, that can be drunk as is without having to pour the beer into a bottle. is not generated.

Furthermore, it has been known that tapping the bottle immediately after filling the bottle with beer during the beer filling process or the like promotes the vaporization of dissolved carbon dioxide. However, in the case of canned beer, after opening the container,
Even if the container was hit with a stick or the like, the beer inside the container did not produce fine creamy foam.

The present applicant has studied a means for forming fine bubbles on the surface of canned beer, etc. when drinking it, and published Japanese Patent Publication No. 61-40781, Utility Model Application Publication No. 61-38033, and Utility Model Application Publication No. 61-38033.
No. 61-38034 and Utility Model Application No. 61-35647 proposed a foam generator that was attached to the bottom of a beer container and applied vibration to the can and beer.

(Problem to be solved by the invention) When using the vibration-applying foam generator described above, when drinking canned beer, etc., the drinker lifts the notch of the foam generator with his or her fingers and releases it elastically. By doing so, the bottom of the can is struck, but since the notch is installed in a certain direction, it is somewhat difficult to lift it without groping, and a solution has been sought.

(Means for solving the problem) In view of this problem, the present invention provides a non-directional foam that can hit the bottom of the beer can by lifting the hitting protrusion from any corner position in the circumferential direction of the beer can. Provide generators.

That is, the present invention includes a disk-shaped fixing part,
A first annular part surrounding the fixing part and a second annular part surrounding the first annular part, wherein the fixing part and the first annular part are part of the circumference of both. are interconnected by a first elastically deformable bridge section,
Further, the first annular portion and the second annular portion are connected to each other by a second bridge portion at a circumferential position diametrically opposed to the first bridge portion, and the first annular portion is connected to the second annular portion by a second bridge portion. Beer foam, characterized in that a striking protrusion is provided on one or both surfaces near the second bridge portion of the section and/or over the entire circumference of one or both surfaces of the second annular section. Provide generators.

(Function) According to the above means, since the second annular portion is located at the outermost periphery of the beer foam generator, when drinking beer, the drinker opens the can and then presses the bottom of the can. The second annular portion can be easily searched for with a finger, and the striking protrusion can be applied to the can bottom from either direction on the circumference of the second annular portion.

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

One embodiment of the beer foam generating device according to the present invention has the shape shown in FIGS. 1 and 2, and is used while being fixed to the bottom wall 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, a first annular part, that is, an annular notch part 3 surrounding this, and a second annular part, that is, an annular grip part that concentrically surrounds this. It consists of 4. The fixing part 2 and the notch part 3 are connected at a part of the circumference by a first bridging part 5 made of an elastic material, and the notch part 3 and the grip part 4 are diametrically opposed to the first bridging part 5. They are connected by a second bridge portion 6 located at a circumferential position. The free end region of the notch part 3, that is, the part 3a on the side far from the first bridge part 5, has a projection on the side facing the can bottom when the foam generator 1 is attached to the can bottom. 7 is provided protrudingly. It is preferable that the protrusions 7 are also provided symmetrically on the back side as will be described later.

As shown in FIG. 3, the foam generator 1 is fixed to the bottom wall surface 9 of a beer can with an adhesive 11 or the like. When drinking beer, the drinker opens the can and then gropes around the bottom of the can to grasp the grip part 4. Since the grip part 4 is located at the outermost periphery of the foam generator 1,
You can easily search with your fingers.

Next, pull the grip 4 away from the can bottom wall 9 with your fingertips. At this time, if the position of the finger is near the second bridge part 6 of the grip part 4, the free end part 3a of the notch part 3 will be connected to the first part together with the grip part 4 via the second bridge part.
Since it is lifted using the bridge part 5 as a fulcrum, when the finger is released, the projection 7 hits the can bottom wall 9 vigorously by the elastic force of the first bridge part 5. On the other hand, when you pull the vicinity of the free end 4a of the grip part 4 with your fingers, the free end 3a side of the notch part 3 is pulled through the second bridge part 6, so that the notch part 3 is connected to the first bridge part 6. It is elastically deformed using part 5 as a fulcrum. Therefore, when the user releases his/her finger from the grip 4, the protrusion 7 hits the bottom wall 9 of the can vigorously.

Even when the grip part 4 is pulled with a finger at a position on the circumference intermediate between the first bridge part 5 and the second bridge part 6, the free end of the knob part 3 is Since the side 3a is elastically deformed in the direction away from the can bottom using the first bridge portion 5 as a fulcrum, the protrusion 7 can impact the can bottom wall 9 in the same manner as described above. In other words, the impact action of the projection 7 on the can bottom wall 9 can be obtained no matter where the grip portion 4 is pulled.

In this way, the impact applied to the can bottom wall 9 by the protrusion 7 causes the can wall to vibrate, and the vibration further propagates to the beer itself inside as a compression wave, causing the carbon dioxide dissolved in the beer to vibrate. It vaporizes the gas and generates fine bubbles concentrically around the point of impact, forming a layer of creamy bubbles on the surface of the beer.

As shown in FIG. 2, this foam generator 1 is preferably vertically symmetrical and integrally molded of synthetic resin or the like.

Further, it is preferable that the fixing part 2 is formed into a convex surface having a curvature that matches the curvature of the concave surface of the bottom wall 9 of the can to be attached, and furthermore, a number of parallel grooves 10 are provided on the convex surface.

Another aspect of the beer foam generator according to the present invention is described in the fourth embodiment.
As shown in the figure. In FIG. 4, the same reference numerals are given to the same components as those of the bubble generator shown in FIGS. 1 and 2 above.

In the beer foam generator shown in FIG.
is provided, and the first annular portion 3 is not provided with such a protrusion.

In the case of this foam generator, if you pinch any point on the circumference of the second annular part 4 and pull it in the direction away from the bottom of the can, then release the second annular part 4 from your fingers. The protrusion 8 near the location where the user was picking hits the outer wall of the bottom of the can. Therefore, the second
No matter where the annular part 4 is pinched, the projection 8 can strike the bottom of the can.

Although two aspects of the present invention have been described above, the present invention is not limited to these aspects.
For example, the protrusion 7 may be provided only on one side of the first annular portion near the second bridge portion, or the protrusion 8 may be provided only on one side of the second annular portion over the entire circumference. Further, the protrusion may be provided on one or both surfaces of the first annular portion near the second bridge portion, and may also be provided on one or both surfaces of the second annular portion over its entire circumference. Further, a protrusion may be provided on the second bridge portion.

(Effects of the invention) As detailed above, according to the invention, the first annular part and the second annular part are provided concentrically as a double ring around the fixed part, and the fixed part and the first annular part are provided concentrically as a double ring. Since the annular part, the first annular part, and the second annular part are connected at diametrically opposing positions by bridge parts each made of an elastic member, which part of the outer second annular part can be connected to the can bottom wall. Even if the can is pulled in a direction away from the can bottom, the protrusions provided on the first annular portion and/or the second annular portion can effectively impact the can bottom.

Further, in a preferred embodiment, the foam generating device of the present invention is vertically symmetrical, so that the installation process can be carried out without paying attention to the front and back sides of the can bottom, thereby improving efficiency.

Furthermore, since the curvature of the convex surface of the fixing part is made the same as that of the concave surface of the can bottom, alignment of the two during the installation work is easy, and the bonding area is increased, allowing for strong installation.

Furthermore, since a large number of parallel grooves are provided on the convex surface of the fixing part, the amount of material can be reduced, and during the installation process, the adhesive flows over the entire surface along the grooves, so that the adhesive can be used effectively. Furthermore, since the adhesive adheres to the inner wall surface of the groove, a fixing effect can be achieved.
