摘要： An insulating cover for a container has a substantially cylindrical sidewall member and a contiguous bottom member. The sidewall and bottom members are preferably formed from a thin sheet of insulating material. The sidewall member has end sections that overlap in an unexpanded orientation. The bottom member has an annular portion than can be adapted to engage the bottom of the container. In another embodiment, a number of substantially identical tabs engage the bottom of the container. The tabs extend from the inner radius of the bottom member annular portion toward the axis of the sidewall member, and are spaced apart so that they do not overlap.

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).
