Description
Technical Field
[0001] This utility model relates to the technical field of food preservation, freezing and insulated cups, specifically a round, disc-shaped ice tray food preservation, freezing and insulated cup. 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, some insulated cups with vacuum insulation layers have appeared on the market, connected to an insulated lid via a connector to form a sealed thermos. However, the connector in these cups does not effectively isolate heat conduction between the inside and outside of the cup, resulting in significant heat transfer at the connector and preventing them from effectively keeping drinks hot for extended periods. Meanwhile, some insulated cups with vacuum insulation layers and a directly sealed lid with an insulated lid also exist, featuring a cylindrical ice tray. However, these are bulky and inconvenient to carry. To address these issues, the inventor designed a thermos with a round, disc-shaped ice tray for both hot and cold storage. Utility Model Content
