Description

Technical Field

[0001] This utility model relates to a food preservation and freezing thermos cup, specifically a food preservation and freezing thermos cup with a sealed bottom and an open top cylindrical ice tray. Background Technology

[0002] Beverages such as breast milk, formula, and water typically require refrigeration to prevent spoilage, and some drinks taste even better after freezing. Traditionally, beverages are refrigerated directly, for example, by expressing breast milk using a breast pump and then storing it in the refrigerator. However, refrigerators are usually large, stationary appliances that require a power source and a fixed location, lacking portability and making refrigeration impossible anytime, anywhere. To achieve portability and keep drinks warm, users often carry a container of ice and place the beverages inside. However, the ice tends to settle at the bottom of the container, resulting in uneven temperature distribution.

[0003] Therefore, a type of insulated cup with a vacuum insulation layer has appeared on the market. The cup body and the insulated lid are connected together via a connector to form a sealed hot and cold insulated cup. However, the connector of this type of insulated cup does not effectively isolate heat conduction between the inside and outside of the cup; a large amount of heat conduction occurs at the connector, causing this type of insulated cup to not effectively keep food warm for a long time. To address this problem, the inventor designed a fresh-keeping and freezing insulated cup with a sealed bottom and an open top cylindrical ice tray. Utility Model Content

[0004] The purpose of this invention is to provide a cylindrical ice tray with a sealed bottom and an open top for preservation, freezing, and thermosing. It has the advantages of simple structure, reasonable design, easy portability, and good refrigeration and heat preservation effect, thus solving the problems mentioned in the above-mentioned technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cylindrical ice tray with a sealed bottom and an open top, comprising a cup body, a lid, and an ice tray. The cup body is a hollow cavity structure with an opening at the top. The cup body includes an outer shell and an inner liner disposed within the outer shell. A vacuum insulation layer is provided between the outer shell and the inner liner. A step is provided on the inner liner. The ice tray is disposed within the inner liner and includes an outer shell and an inner shell disposed within the outer shell. The outer shell and the inner shell are welded together, and a space is provided between the outer shell and the inner shell. A receiving area is formed, in which a heat storage medium is filled. The inner shell of the ice tray has a placement cavity for placing the inner container. The cup lid is placed on the opening of the cup body and can open or close the cup body.
