Container insulator
摘要:
An insulating cover is provided for a beverage container (24). A resilient cylindrical sidewall member (10) is slit (18) with overlapping edges (20 and 22) for expansion and contraction. A plurality of bottom segments (12) depend from the sidewall in an iris-like configuration to enlarge or contract with the sidewall (10) while maintaining support for the enclosed container (24).
