Estimating the term…
An insulative member for surrounding and embracing an exterior surface of a hot-beverage drink cup to provide a grippable low-temperature thermal barrier that can be gripped by a consumer, the member comprising a sheet comprising insulative cellular non-aromatic polymeric material having localized plastic deformation in the sheet and providing a plastically deformed first material segment having a first density located in a first portion of the sheet and a second material segment having a second density lower than the first density located in an adjacent second portion of the sheet.
An insulative sleeve for surrounding and embracing an exterior surface of a hot-beverage drink cup to provide a grippable low-temperature thermal barrier that can be gripped by a consumer, the sleeve comprising a sheet comprising insulative cellular non-aromatic polymeric material having localized plastic deformation in the sheet and providing a plastically deformed first material segment having a first density located in a first portion of the sheet and a second material segment having a second density lower than the first density located in an adjacent second portion of the sheet, wherein the sheet has no fractures in the insulative cellular non-aromatic polymeric material so that a predetermined insulative characteristic is maintained in the sheet.
