Insulative container

An insulative container comprising a wall and a floor, the wall being coupled to the floor, the wall comprising insulative cellular non-aromatic polymeric material having localized plastic deformation to provide a plastically deformed first material segment having a first density located in a first portion of the material and a second material segment having a second density lower than the first density located in an adjacent second portion of the material, wherein the insulative cellular non-aromatic polymeric material has no fractures so that a predetermined insulative characteristic is maintained in the material,

• wherein the wall is arranged to surround a vertical central axis and includes an upright inner tab arranged to extend upwardly along and in spaced-apart relation to the vertical central axis and is configured to provide the first material segment having the first density, an upright outer tab arranged to extend upwardly along and in spaced-apart relation to the vertical central axis and arranged to mate with the upright inner tab along an interface therebetween, and an upright fence arranged to interconnect the upright inner and outer tabs and surround the vertical central axis and configured to provide the second material segment having the second density and cooperate with the upright inner and outer tabs to form the wall.
