For example, frozen or chilled products such as shaved ice or ice cream, and hot water. It is attached to the outer peripheral side surface portion 4 of the container body 3 that stores high-temperature products such as hot drinks and hot drinks by thermal contraction.

As the heat insulating sheet body 2 adhered to the inner surface of the shrink film 1, one having a width narrower than the height of the shrink film 1 is used.
At the portions that become the upper and lower end portions 9 and 10 in the height direction of 1, the container contact pieces 13 and 14 that project longer than the upper and lower end portions 11 and 12 in the height direction of the heat insulating sheet body 2 are provided. Piece
