摘要

Double-walled container (1) comprises a composite tub (2) with an outer shell (3), a device (4) for cold storing, which is present between the tub and the outer shell, and a temperature display device for sufficient cooling of the device for cold storing. The temperature display device comprises a label with at least one mark, which is made of reversible thermochromic ink with a negative temperature of transition threshold value. An independent claim is also included for an ice machine for the cold storing, comprising the above double-walled container, blades arranged in the double-walled container, and a driving device for producing a relative rotational movement between the blade and the double-walled container.
