Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention relates to a glass container for beer beverages such as glasses and mugs having a foaming property.

(Prior art) There are two conditions for tasting beer deliciously: to cool the throat and stimulate the throat, and to form a layer of persistent foam on the surface of the liquid to prevent carbon dioxide from scattering. There is a factor. However, there is a contradiction that when beer is cooled, the foaming becomes worse, the foam layer disappears in the middle of the foam, carbon dioxide gas escapes, and so-called beer is easily released.

In order to compensate for this, conventionally, as a container for promoting a foaming action, a container made of pottery in which the skin of the unglazed surface is directly exposed and the unevenness is carved without glaze is disclosed in Japanese Utility Model Publication No. Sho 61-73279. Is proposed as.

However, in such means, since the unglazed surface is porous and has deep holes, if this is exposed on the inner wall surface of the container, water will remain in the holes after use, and bacteria will easily grow due to humidity and lack of ventilation. , Hygiene will not be a problem. Further, even when it is washed, it cannot be washed to the inside of the hole, and there is a drawback that it is not practical as a beverage container that should be hygienic.

In addition, since the biscuit surface has irregularities with extremely large diameters and is uneven in size and size, the bubbles produced do not necessarily become fine, sustained bubbles, and there is a tendency that the bubbles disappear during the process.

Furthermore, since the pottery does not transmit light, it is not possible to see the clear beer liquid poured into the container, the unique taste of beer that exhilarates is lost, and the enjoyment of beer to taste is deprived. It has the drawback of being broken.

(Problems to be Solved by the Invention) The present invention has been made based on the above-mentioned circumstances, and is intended only for glass containers that remain transparent or translucent. We will try to develop a container that is creamy and has good sustainability, and that can be handled hygienically. Further, the above-mentioned container also has a problem that the inner wall becomes wet after pouring beer once and the foaming property is lost. Therefore, it is an object to solve this problem.

(Means for Solving the Problem) The container for beer beverage of the present invention forms an erosion surface by an acid solution such as hydrofluoric acid at a portion of the inner wall of the glass container which is in contact with the beer liquid while flowing down, and the surface of which is water repellent. The material is coated so that creamy bubbles are continuously generated by the turbulent flow occurring on the eroded surface.

(Function) Hydrofluoric acid forms an erosion surface with extremely fine holes, and when the beam is poured into it, static turbulence occurs,
The foaming action is induced and creamy foam is formed on the surface. Furthermore, since the surface of the eroded surface is coated with a water repellent material such as silicone, even after the beam has been once poured, the liquid is repelled and the surface is not wet and the foaming action is repeatedly caused. The creamy foam becomes a long-lasting foam, prevents carbon dioxide from scattering, has a refreshing and cohesive taste until the end, and prevents deterioration of taste due to air oxidation. In addition, since the erosion surface has a shallow groove, it is easy to clean, and it naturally dries, prevents the growth of microorganisms, and is extremely hygienic.

(Example) Hereinafter, based on an example, 1 is a container for beer drink, and it is a transparent or translucent glass container such as a glass, a cup or a jug so that the user can enjoy a refreshing feeling with eyes.

Then, on the inner wall of this glass container, an erosion surface 1a with an acid such as hydrofluoric acid is formed at a portion where the beer liquid comes into contact while flowing down.

The erosion effect by acids such as hydrofluoric acid is to promote the elution by selectively exchanging hydrogen ions in the acid solution with the alkaline components in the glass. When hydrofluoric acid is used,
Hydrogen fluoride, in response to the structure itself is dissolved in water tends silicon fluoride acid (H ₂ Si silicic acid constituting the glass (SiO ₂₎
F ₆ ) is produced, and this fluorosilicic acid is gradually released from the surface to promote elution.

Since this elution is due to ion elution, the erosion surface 1a is engraved with extremely fine grooves of a few microns, and the distribution of the irregularities is a uniform combination of concaves and convexes. . This fine and uniform concave and convex groove structure is an extremely effective structure for forming a creamy foam described later.

Further, the erosion surface 1a is coated with a water repellent material 1b, for example, silicone oil is diluted with a solvent such as toluene or xylene, and then applied, and heated at 120 to 250 ° C. for about 5 hours to be several microns. To form a film. The water repellent material 1b prevents the surface of the beer liquid from being wet by repelling beer liquid, and examples thereof include fluororesins and the like in addition to the silicone.
Among these, since the silicone resin has silicon (Si) as a main component, it has a part of the same component as glass and good adhesiveness, and is suitable for coating glass. In addition, since it maintains transparency, it has excellent visibility.

And, the place to form this eroded surface 1a, on the inner wall of the glass container, when pouring the beer liquid, the liquid is a portion that comes into contact while flowing down, and the side surface of the container has a height of about 2/3 or less from the bottom. It is included.

Then, visually, it is desirable to leave the transparent portion in part so that the beer liquid can be seen from the outside, and it is preferable to further add decoration to form the eroded surface 1a in a designed pattern. As shown in FIG. 3, the mode is a striped pattern in which the erosion surface 1a is applied to vertical or horizontal stripes (see FIG. 3A), or a grid pattern with vertical and horizontal gaps (see FIG. 3). (See FIG. 3B), or a spiral pattern with swirled lines can be used (see FIG. 3C). To create this pattern, an acid resistant agent such as wax may be applied to the inner wall surface, and the coating of the acid resistant agent may be scraped off with an iron brush or a spatula to draw the pattern.

Next, the operation of this embodiment will be described. First, in order to drink beer deliciously, it is necessary to cool the beer so that it stimulates the throat, and this chilled beer is poured into the glass of the present invention. Here, the beer liquid flows down on the inner wall surface of the inclined glass and comes into contact with the eroded surface 1a of the inner wall.

Then, as shown in FIG. 2, at the boundary with the erosion surface 1a,
The flow of beer liquid is disturbed, and when viewed microscopically, a small vortex is generated, and this vortex causes a pressure difference between the pressurizing part and the negative pressure part, and this pressure difference triggers melting. Carbon dioxide gas is vaporized and a foaming action is caused. The foaming action becomes smaller as the pressure difference is as small as possible (static turbulent flow), and the number of bubbles becomes larger as the number of locations where the pressure difference becomes the bubble nucleus increases. That is, the structure of the contact surface that produces a pressure difference is suitable for generating smaller bubbles as the number of grooves is smaller and the number thereof is larger. Since they are alternately combined and uniformly engraved, they are suitable for causing static turbulence. In fact, according to the container of the present invention, fine creamy bubbles are formed, which is in good agreement with the above description.

Then, compared to the large bubbles, the small bubbles are less likely to be crushed and disappear in the middle, and become bubbles having a long duration. That is, the component of this foam is a complex of isohumulone, which is a bitter ingredient of beer, and foaming protein, and this complex forms a foam by forming a film. Depending on the condition, large bubbles tend to be easily crushed by the pressure of the surroundings, and conversely, smaller bubbles have a higher surface tension and become sustainable and good quality bubbles.

Now, when this high-quality creamy foam is formed on the surface, this layer of foam prevents carbon dioxide from escaping from the inside of the beer, and the refreshing effect of carbon dioxide, which is the cause of the beer's deliciousness, is refreshed. It retains good stimulation and a cohesive taste. Therefore, the conventional contradiction that cold beer is easily bubbled in the middle due to poor foaming is resolved, and cold and delicious beer can be tasted until the end. It also acts to prevent direct contact between beer and air to prevent deterioration of taste due to oxidation.

By the way, also in the foaming action, once the beer liquid is poured and the surface gets wet, the erosion surface 1a which should cause turbulence becomes smooth, and therefore when the liquid is poured a second time, the foaming action may be halved. There is. However, since the water repellent material 1b such as silicone is applied in the present proposal, the surface of the erosion surface 1a is not lost because the poured beer liquid is not repelled to wet the surface. Therefore,
Even if repeated twice or three times, the foaming action does not decrease, and the delicious beer can be continuously enjoyed.

The hydrofluoric acid solution eroded surface 1a has an extremely shallow groove, so that it can be naturally dried if left after washing, and there is no fear that bacteria will propagate. Also, the cleaning can be performed by immersing it in a detergent and rubbing it like a normal glass container.

Furthermore, since this rough surface 1a is semi-transparent and the beer liquid can be seen from the outside, the refreshing feeling of beer can be visually enjoyed, and at this time, it can be striped, latticed, spiraled, or the like. For example, you can enjoy its ornamental contrast with the transparent part.

(Effect) Based on the above configuration and operation, the present invention has an excellent feature that creamy foam can be formed by the eroded surface, a refreshing and cohesive taste can be enjoyed to the end, and the taste of beer is brought out by the container. Produce the effect. Also, since it is the erosion surface of the water repellent material, even when repeatedly poured into the same container twice or three times, the foaming action of the erosion surface does not decrease,
You can enjoy delicious beer continuously. and,
Since it can be handled hygienically, it is suitable for beverage containers, and it can be mass-produced and is economical.
