Abstract

PURPOSE:To provide a space saving and enable a glass cooling to be carried out at a desired location by a method wherein a disk-like injection plate is pushed down against a biasing force of a spring, and then a nozzle and a gas injection hole communicate with each other to injected liquefied carbonic acid gas, and a dispenser for liquid beverage and a liquefied carbonic acid gas bomb are used in common. CONSTITUTION:As a glass is set in an upside-down state to cover an injection head 1 and lightly pushed on an injection plate 6, a nozzle 4 descends to cause a hole 7 at its extreme end to communicate with an injection hole, 2 resulting in that liquefied carbonic acid gas is injected into the bottle. In this way, the injecting operation is continued to complete a cooling of the glass. After completion of the cooling operation, a force which has pushed down the glass is released and a nozzle 4 and an injection plate 6 are lifted up by a biasing force of a spring 3, a hole 7 of the nozzle 4 is closed and a supplying of the liquefied carbonic acid gas toward the injection head 1 is stopped. A liquefied carbonic acid gas supplying tube 5 is connected to a bomb 9 for a liquid beverage dispenser for beer or the like. In this way, the liquid beverage dispenser for beer or the like and the bomb are used in common to reduce a mounting space for the bomb.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a glass cooling device. More specifically, the present invention relates to a glass cooling device that utilizes liquefied carbon dioxide gas branched from a gas cylinder for dispensing liquid beverages such as beer, and is space-saving and compact.

[Conventional technology] Conventionally, when drinking cold carbonated drinks such as beer, cola, and cider, when poured into a warm glass at room temperature, carbon dioxide gas rapidly escapes, spoiling the original taste of the carbonated drink. Not only that, but the visual taste is also reduced by half, so the glass was chilled in the refrigerator beforehand.

However, if a large number of glasses are used, a large-capacity refrigerator is required, which has the problem of taking up a large amount of space and taking a long time to cool the glasses.

For this reason, in recent years, direct cooling type instant coolers that utilize the cold energy generated when liquefied carbon dioxide gas is vaporized have been used. This cooler cools the glass by injecting liquefied carbon dioxide gas from a dedicated liquefied carbon dioxide gas cylinder toward the inner surface of the glass through an injection hole.

[Problems to be Solved by the Invention] However, in most places where the glass cooler is used, liquid beverage dispensers are also used, and the same liquefied carbon dioxide gas is used. Despite this, each gas cylinder was supplied with gas from a separate cylinder, and there was a waste of space due to the gas cylinders. Further, in conventional glass coolers, the gas injection part and the gas cylinder are integrated, and it is not possible to install only the gas injection part at a convenient location for serving liquid beverages.

In view of the above circumstances, the present invention is a glass cooling device that can effectively utilize a liquefied carbon dioxide gas cylinder, save space, and cool glasses by providing a gas injection section at a desired location. The purpose is to provide

[Means for solving the problem] The glass cooling device of the present invention is a device that injects liquefied carbon dioxide gas onto the inner surface of the glass and cools the glass with the cold heat generated when the liquefied carbon dioxide gas vaporizes. From an injection head having a gas injection hole that is always closed due to force, a nozzle provided within the injection head and connected to a liquefied carbon dioxide supply tube, and a disc-shaped injection plate fixed to the outer periphery of the nozzle. By pushing down the disk-shaped injection plate against the biasing force of the spring, the nozzle and the gas injection hole communicate with each other to inject liquefied carbon dioxide, and the liquefied carbon dioxide gas is supplied. It is characterized in that the tube is branched from a liquefied carbon dioxide gas supply tube for a liquid beverage dispenser.

[Example] Hereinafter, a glass cooling device of the present invention will be explained based on the accompanying drawings.

FIG. 1 is a schematic explanatory diagram of an embodiment of the glass cooling device of the present invention.

In FIG. 1, fl) is an injection head having a gas injection hole (2) which is normally closed by the biasing force of a spring.

It is preferable to form a plurality of gas injection holes (2) from the viewpoint of uniformly and efficiently cooling the inner surface of the glass in a short time, and these injection holes (2) are arranged at equal intervals so as to face diagonally upward. It is preferable to place

A gas injection nozzle (4) is provided in the injection head (1), and a liquefied carbon dioxide gas supply tube (5) is connected to the base end of this nozzle (4).

A disk-shaped injection plate (6) is fixed to the outer periphery of the nozzle (4). Then, when the glass is turned upside down and lightly pressed onto the injection plate (6) so as to cover the injection head (1), the nozzle (4) descends and connects the hole ('7) at its tip with the injection hole. c'2J communicates, and liquefied carbon dioxide gas is injected into the glass.

In this way, cooling of the glass is completed by continuing to press the spray plate (6) for several seconds with the glass, but after cooling is completed, by releasing the force holding the glass, the nozzle (4) is activated by the biasing force of the spring (3). and the injection plate (6) rises to open the hole (7) of the nozzle (4).
is closed, and the supply of liquefied carbon dioxide gas to the injection head (1) is stopped.

The liquefied carbon dioxide supply tube (5) is connected to an appropriate branching device (8
) to a bong (9) for liquid beverage dispensers such as beer, cider, cola, and chu-hi.

In this way, by sharing the cylinder with a liquid beverage dispenser such as beer, the installation space for the cylinder can be reduced.

In addition, the glass cooling unit and the cylinder can be separated, allowing the glass to be cooled at a convenient location for serving beverages (for example, at the end of the counter or at a service table), for example when pouring draft beer. It becomes possible to cool glasses on the spot, and it also becomes possible to perform a flexible store contract design or plan.

[Effect of Light] As explained above, according to the glass cooling device of the present invention, since the liquid beverage dispenser and the gas cylinder are shared, it is possible to save space and to move the cooling part away from the cylinder. This has the effect that the glass can be cooled at an appropriate location by separating it.
