Description

Insulated beverage container

Technical field

The utility model relates to the field of daily necessities, in particular to a beverage container.

Background technique

Drink containers are common containers in people's daily lives, such as cups, kettles, milk cups, hot pots, etc. The commonly used cups or kettles have only one outer casing. When used, water or drinks are put into the outer casing. If the winter or summer is too cold or too hot, the loaded drinks cannot be heated or cooled.

In order to overcome this disadvantage, Chinese Patent No. 201120148362.7 discloses a bone china liner cup, which comprises a cup lid and a cup shell. The inner cavity of the cup shell is provided with a bone china liner, the inner wall of the cup shell and the outer wall of the bone china liner. The filling and insulating material is sealed and fixed, and a sealing ring is arranged at the upper part of the cup shell and the inner bone of the bone china. The thermos cup is formed by integrating the cup shell with the bone china inner liner, and the insulating material is filled between the cup shell and the bone china inner liner, and the heat insulating material is quickly solidified to seal and fix.

The disadvantage of such a thermos cup is that it does not allow heating or cooling of the beverage in the liner.

Summary of the invention

In order to overcome the disadvantage that the existing insulated beverage container has the function of not heating or cooling the beverage in the inner liner, the utility model provides an insulated beverage capable of heating or cooling the beverage in the inner bladder. container.

The insulated beverage container comprises a casing and a liner disposed in the casing, the casing comprises an outer casing and an inner casing, a vacuum chamber is formed between the outer casing and the inner casing, and the inner casing is A medium cavity for filling the heat transfer medium is formed between the inner tanks, wherein an elastic member is disposed between the bottom of the inner casing and the bottom of the inner casing, and the inner casing is matched with the outer casing, and the outer casing is connected with the upper cover. The connecting member is provided with a sealing ring between the upper cover connecting member and the outer casing, the sealing ring closes the gap between the inner casing and the outer casing, and the elastic member is compressed when the upper cover connecting member is fixed with the outer casing; the upper cover connecting member is provided with a drink outlet.

In order to clarify the mounting position of the elastic member, it is further defined that the elastic member is mounted on the bottom of the inner tank, and the bottom of the inner casing is provided with a groove for allowing the elastic member to be inserted.

The elastic member is an elastic pad or a spring. The elastic member may be made of an elastic material such as a silicone pad or a rubber pad. The spring is a cylindrical spring.

In order to prevent excessive addition of the heat transfer medium, the heat transfer medium overflows when the liner is inserted, and further defines that the inside of the outer casing is provided with an upper limit of the medium capacity. When the amount of the heat transfer medium reaches the upper limit, the inner casing is placed in the outer casing, and when the inner casing is pressed by the upper cover connecting member, the heat transfer medium just fills the entire medium cavity. Due to the action of the elastic member, the inner liner is fixed between the sealing gasket and the sealing ring, and the sealing gasket closes the gap between the inner liner and the outer casing. When the utility model is used, the heat transfer medium does not overflow.

In order to facilitate the identification of the temperature of the beverage, it is further defined that the outer surface of the inner tank is provided with a temperature sensing material.

Further, the outer casing is a double metal container. Such as double stainless steel containers.

Further, the inner liner is a glass liner, a plastic liner, a metal liner, or a ceramic liner. When the inner tank is a glass liner, the outer side of the inner tank is provided with a capacity scale line.

The inner tank may also be a double-layer stainless steel structure, the inner casing including an inner crust and an outer crust, and the inner crust and the outer crust are filled with a heat absorbing medium.

The advantages of the utility model are:

1. The heat transfer medium is injected into the outer casing, and the inner casing is placed in the outer casing, and the inner casing is surrounded by the heat transfer medium. When the temperature of the beverage is too high, the heat transfer medium uses a normal temperature liquid or a low temperature medium. When the temperature of the beverage is too low, the heat transfer medium uses a high temperature liquid. The use of heat transfer between the heat transfer medium and the beverage allows the beverage to cool down quickly or rapidly. And when the temperature of the beverage and the heat transfer medium is equalized, the heat transfer medium functions to isolate the temperature of the beverage from the external environment, so that the beverage maintains a suitable temperature for a long time.

2. The upper cover connecting piece and the elastic member work together to fix the inner liner, and the sealing ring closes the medium cavity to prevent the heat transfer medium from leaking out, and is convenient for the user to directly quote the drink in the inner tank, and is convenient to use.

3, a cup of dual use. Both the outer casing and the inner liner can be used in separate containers.

4, the liner can be removed, the outer casing and liner are easy to clean, to prevent bacterial growth.

5. The heat transfer medium heats or cools the beverage through the inner tank. It is not necessary to directly add cold water or hot water to the drink, which will not dilute the taste of the drink and taste good.

6. The gap between the inner liner and the outer casing is closed by the sealing ring, and there is no direct fixed relationship between the inner liner and the outer casing. Therefore, the material for making the inner liner is not limited, and the connection problem with the outer casing is not considered.
