Abstract

PURPOSE: To continuously foam carbonated gas bubbles which are supersaturated in a carbonated beverage at the time of pouring it into a container by leaving a little amount of air on the recessed/projected surface of a container base surface. CONSTITUTION: A sharp recessed groove 3 is formed in a container where the carbonated beverate is poured for drinking and in a base surface part 2 of an inner part in the fixed space of the container for storing the carbonated beverage. Or, porous substance is adhered so that a carbonated gas molecule dissolved in a solution is permitted to flow into small air foams P which remain on a fine recessed and projected surface 4 in the groove 3. The air bubbles whose quantity is increased by the flowing-in remain by original quantity, the foams for the portion of flowing-in quantity ascend and are bubbled, and this kind of activation is continued.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention, when a carbonated beverage supersaturated with carbon dioxide gas is poured into a container such as a cup, continuously generates carbon dioxide gas bubbles from the beverage in the container, causing the water to rise from the bottom of the container to the water surface. The present invention relates to a method for foaming a carbonated beverage in which the beverage is made to rise continuously to foam and swell, and a container for the foaming method.

The present invention allows a small amount of air to remain on the uneven surface of the bottom of the container when pouring the carbonated beverage into the container, so that supersaturated carbon dioxide gas bubbles are continuously foamed in the carbonated beverage. It is characterized by:

The object of the present invention is to not only cause carbonated drinks to foam when poured into a container such as a cup, but also to cause bubbles of carbon dioxide gas to continuously form on top of the drink in a transparent glass cup when poured and placed. The purpose is to provide a container such as a hanging cup that gives a visually refreshing feeling by flowing water and improves the foaming ability and foam retention ability, which are the main quality factors of carbonated drinks. be.

Originally, carbonated drinks were made by mixing and dissolving carbon dioxide gas in a solution, and assuming that the carbon dioxide gas molecules were evenly distributed among the water molecules, it would be as shown in the example diagram in Figure 1. Water molecules and carbon dioxide molecules will form a regular arrangement.

However, since the bond between water molecules and carbon dioxide molecules at this time is not a chemical bond, the bonding force is extremely weak.

Generally speaking, carbonated drinks such as cider cola have about 2 to 6 volumes of carbon dioxide dissolved in them, and when poured into a cup, the internal pressure suddenly drops in a sealed bottle with high pressure, resulting in supersaturated dissolution. Most of the carbon dioxide gas bubbles on the surface of the drink and escapes into the atmosphere, and some carbon dioxide gas forms bubbles from the sides or bottom of the cup and escapes into the atmosphere on the surface of the drink, eventually becoming a saturated carbonated drink. Become.

At this time, if a small amount of air bubbles remain inside the container of the supersaturated carbonated drink, carbon dioxide gas moves to the small amount of air bubbles at the 6° boundary between the small amount of air bubbles, and the supersaturated carbonated drink becomes stable. become 6° interface between carbonated beverage and a small amount of air bubbles
The phenomenon in which carbon dioxide gas evaporates into a small amount of air bubbles through the carbonated beverage is the same as the phenomenon in which carbon dioxide gas evaporates into the atmosphere through the interface 6 between the atmosphere and the carbonated beverage. A small amount of air bubbles increases in volume as liquid carbon dioxide receives gaseous carbon dioxide.

The small amount of air bubbles that have increased in volume remain attached to the uneven surface 4 by the volume of the original small amount of air bubbles, and the air bubbles that have increased by the amount of carbon dioxide gas introduced by the supersaturated carbonated beverage have buoyancy. (Figure 2).

The small amount of air that may remain attached to the uneven surface 4 is as follows:
There are differences depending on the structure of the uneven surface, the material, the type of carbonated beverage, the degree of supersaturation, temperature, specific gravity, viscosity, permeability, etc.

Normally, small amounts of air bubbles that remain attached to uneven surfaces can be removed by repeating the above process.
It acts like a catalyst in chemical reactions and has a sustained foaming property.

As the carbon dioxide gas bubbles rise, carbon dioxide gas continuously flows in from the supersaturated carbonated beverage, and the more firmly the carbonated beverage rises, the lower the external pressure becomes, and the volume of the carbon dioxide gas bubbles increases.

When the carbon dioxide bubbles rise, the supersaturated carbonated beverage will undergo internal circulation to continuously supply the supersaturated carbonated beverage to the small amount of air bubbles, and the small amount of air bubbles will continue to absorb carbon dioxide until it becomes a supersaturated carbonated beverage. It acts as a catalyst to generate bubbles (Figure 3).

The effect of the present invention is that when a carbonated drink is poured into a container such as a cup, a large amount of carbon dioxide gas bubbles are generated in a short period of time in conventional containers, but a small amount is intentionally poured into the bottom of the carbonated drink container. It has the effect of leaving behind air bubbles to continuously generate a small amount of carbon dioxide gas bubbles, promoting foaming properties and making carbonated drinks under the same conditions feel more refreshing.

Embodiment 1 FIG. 4 is a perspective view of a container which is one of the embodiments of the present invention, and FIG. 5 is a sectional view thereof.

- A sharp groove 3 is cut into the bottom surface 2 of the container 1 to form the foaming container for the carbonated beverage of the present invention.

When the grooves 3 cut into the bottom surface 2 of the container l are enlarged with a magnifying glass, unlike the glass surface, they form a finely uneven surface 4 as shown in FIG. 4A. The depth is shallow enough to be easily cleaned.

When a carbonated beverage is poured into the container 1 of the present invention, a large number of carbon dioxide gas bubbles remaining inside the uneven surface 4 of the groove 3 are absorbed by the carbonated beverage at the groove 3, and a small amount of air bubbles P. A small number of carbon dioxide gas bubbles (
It rises continuously and promotes the effervescence characteristic of carbonated drinks.

When forming the groove 3 by the uneven surface 4 on the bottom surface 2 of the container 1 in Example 1, it is not limited to the horizontal and vertical intersecting lines shown in the drawing, but it is also possible to display pictures, various characters, figures, etc. It can also be displayed in patterns.

Embodiment 2 FIG. 7 shows that grooves 3 are formed in the bottom surface 2 and the lower peripheral surface 2° of both sides of a circular container L made of ordinary glass material by the method of Embodiment 1.
．． A 3° cut is made to form an effervescent cup for carbonated drinks.

In the lower peripheral surface 2'' of the container 1 in this embodiment, a groove of 3 degrees can be cut circularly along the circumference, a groove can be formed locally, and other characters or patterns can be formed. can also be formed.

This is the same as in Example 1 in that foaming is maintained when the carbonated beverage is poured into the container.

Example 3 An inorganic foaming promoter 5 having an uneven surface 4 is embedded in the bottom surface 2 of a vitreous transparent container 1.

This foaming accelerator 5 has an uneven surface like a cross section of broken ceramics, and means an uneven surface that is distinguished from the smooth surface of a glass cup.

As for the material, boiling stones, porous porcelain, earthenware, glass, and metals can also be adhered and formed.

This is the same as in Example 1 in that the carbonated beverage remains foaming when poured into the container.
