Abstract

(57) [Abstract] [Purpose] To provide a liquid cool container in which heat of the outside air is not easily transmitted and can be recooled in a short time. [Structure] An inner container 18 is further disposed inside an outer container 12 having a vacuum double-wall structure other than the bottom, and the bottom of the outer container 12 is a bottom lid 22 formed of a heat insulating material. It is detachably sealed. As a result, the outside air temperature is less likely to reach the liquid 28, and radiant cool air from the cold liquid 28 filled in the inner container 18 is less likely to be discharged to the outside, so that the cold insulation property can be improved. When recooling, the bottom lid 22 of the outer container 12 is removed before the cooler 2
6 is set to cool the liquid 28 through the inner container 18. At this time, since the space 20 is provided around the inner container 18 to increase the cooling area, it is possible to cool in a short time.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a liquid cool container, and more particularly to a liquid cool container that cools and recools a beverage.

[0002]

[Prior Art]

 Conventionally, this type of liquid cold storage container has a double-wall structure, as represented by a thermos bottle, and the space formed by the double-wall structure is evacuated to generate heat insulation. It was supposed to keep the cold liquid filled in.

[0003]

[Problems to be solved by the device]

 However, when the conventional liquid cold storage container is used in an environment with a high outside temperature such as summer, the heat of the outside air is easily transferred to the liquid in the container through the container and the cold heat from the liquid is easily released to the outside. However, the cooling performance was insufficient. In addition, it is troublesome that liquid that has warmed up due to outside air temperature must be transferred from the liquid cool container to another container, recooled in a refrigerator or the like, and then filled in the liquid cool container again. It was In addition, some of the conventional liquid cool containers of this type can be recooled while the liquid is filled in the container, but there is a drawback that it takes a long time to cool.

For this reason, there has been a demand for a liquid cold insulation container which has excellent cold insulation properties and can be easily recooled in a short time. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a liquid cool container that has good cold insulation properties and can be recooled in a short time.

[0005]

[Means for solving the problem]

 In order to achieve the above object, the present invention comprises an outer container and an inner container, has a double-wall structure except the bottom of the outer container, and vacuums the space formed by the double-wall structure. The inside of the outer container is provided with an inner container that communicates with the spout of the outer container and forms a space between the outer container and the outer container, and the bottom of the outer container is formed of a heat insulating material. It is characterized by being provided with a detachable bottom lid.

[0006]

[Action]

 Fill the cooled liquid from the spout of the liquid cool container, close the lid, and place it under hot conditions such as summer. Then, the outer surface of the liquid cool container is heated by the heat of the outside air, but most of the heat is blocked by the outer container having the vacuum wall formed by the double wall structure and the heat insulating bottom lid. In addition, the small amount of heat that cannot be completely shielded by the outer container and the heat insulating bottom cover is again shielded by the space and the inner container that separate the outer container and the inner container.

On the other hand, the cold heat from the liquid is blocked by the inner container, the outer container, and the space separating the inner container, and is further blocked by the outer container. That is, by providing the inner container, it is possible to improve the cold insulation property of the liquid cold insulation container. However, since the liquid gradually warms up due to the outside air temperature or the like in a long time, the bottom lid of the liquid cool container is removed and attached to the cooler, and the liquid is recooled via the inner container. At this time, since the space is provided around the inner container to increase the cooling area, the cooling efficiency is good and the liquid can be recooled in a short time. When the re-cooling is completed, remove the liquid cool container from the cooler, and when the air in the space between the inner container and the outer container is cold, refit the bottom lid to seal the liquid cool container to enhance the cool effect. The cold insulation of the container can be further improved.

【Example】

 Hereinafter, a preferred embodiment of the liquid cool container 10 according to the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, the outer container 12 has a double-wall structure similar to a thermos except for the bottom, and the gap 14 of the double-wall structure is in a vacuum state to improve heat insulation. There is. Further, a spout 16 is provided on the upper portion of the outer container 12, and an inner container 18 communicating with the spout 16 of the outer container 12 is hung from the upper portion of the outer container 12 inside the outer container 12. And a space 20 is formed between the outer container 12 and the inner container 18.

A bottom lid 22 made of a heat insulating material is detachably screwed to the bottom of the outer container 12 to seal the outer container 12. Further, a lid 24 is screwed into a spiral groove 16A formed on the inner surface of the spout 16 provided in the upper part of the outer container 12 to seal the inner container 18. Further, as shown in FIG. 2, at the time of recooling, the bottom cover 22 is removed and a cooler 26 is attached to allow recooling.

The operation of the liquid cold storage container 10 configured as above will be described below. First, a beverage 28 cooled in a refrigerator or the like (not shown) is filled from the pouring port 16 of the liquid cold insulation container 10, the lid 24 is closed, and the cold beverage 28 is stored under hot conditions such as summer when the cold beverage 28 is required. When placed under the above conditions, the outer surface of the liquid cool container 10 is warmed by the heat of the outside air, but the outer container 12 having a vacuum wall formed of a double wall structure and the bottom formed of a heat insulating material. The lid 22 blocks most of the heat. In addition, the heat that has passed without being completely blocked by the outer container 12 and the bottom lid 22 is again blocked by the space 20 and the inner container 18 that separate the outer container 12 and the inner container 18, and the beverage 28 filled in the inner container 18 It becomes difficult for the outside air temperature to be transmitted.

On the other hand, the cold heat from the cold beverage 28 is blocked by the inner container 18 and the space 20 separating the outer container 12 and the inner container 18 and further blocked by the outer container 12, so that the cold heat of the beverage 28 is released to the outside. It becomes difficult to be done. By providing the inner container 18 in this way, it is possible to prevent the heat of the outside air from being transmitted to the beverage 28 as much as possible, and to prevent the cold heat of the cold beverage 28 filled in the inner container 18 from being released to the outside as much as possible. Therefore, the cold insulation property of the liquid cold insulation container 10 can be improved.

However, since the beverage 28 gradually warms up for a long period of time, the bottom lid 22 of the liquid cool container 10 is removed and the cooler 26 is attached instead, so that the cool air generator 28 of the cooler 26 generates the drink. The cold air is applied to the inner container 18 by the fan 30 to recool the beverage 28 via the inner container 18. At this time, since the space 20 is provided around the inner container 18 to increase the cooling area, the cooling air from the cooler 26 hits substantially the entire inner container 18 to improve the cooling efficiency, so that the beverage is cooled in a short time. be able to. Then, when cooling is completed, the liquid cool container 10 is removed from the cooler 28, and while the air in the space 20 between the inner container 18 and the outer container 12 is cold, the bottom cover 22 is fitted again and sealed to enhance the cool effect. Thereby, the cold insulation of the liquid cold insulation container 10 can be further improved.

The outer container having a thermos structure is usually made of hard glass with good heat insulation and a small coefficient of thermal expansion, which is plated with silver, but is not particularly limited as long as it is a material with good heat insulation. Further, in the present embodiment, the cooler for re-cooling uses the air-cooled type, but the cooler is not limited to this, and may be of the type in which a jacket is set in the inner container to circulate cold water or brain. ..
