Container

1 . An insulative container comprising

a container body having a floor, a brim spaced apart from the floor, and a side wall extending between and interconnecting the floor and the brim and extending circumferentially around a central axis of the container body, the side wall being formed to include a plurality of vertically extending ribs spaced apart from one another around a periphery of the side wall and a shoulder coupled to an upper end of the plurality of vertically extending ribs and spaced apart from the brim, and

a container sleeve extending annularly around the side wall and coupled to each of the vertically extending ribs included in the plurality of vertically extending ribs along an outer surface of the side wall,

wherein each vertically extending rib extends only partway along a height of the side wall of the container body from the floor to the shoulder and the sleeve has a lower end coupled to the floor and an upper end that terminates at the shoulder.

2 . The insulative container of claim 1 , wherein the container body includes an insulative cellular non-aromatic material having a polypropylene base resin and the container sleeve includes a heat-shrinkable polymeric material.

3 . The insulative container of claim 2 , wherein the heat-shrinkable polymeric material includes polyethylene terephthalate or polypropylene.

4 . The insulative container of claim 1 , wherein the side wall further includes an annular side-wall sleeve having an outer surface facing away from the central axis and an inner surface facing toward the central axis, and wherein each of the projections is coupled to the outer surface of the annular side-wall sleeve.

5 . The insulative container of claim 4 , wherein the inner surface of the annular side-wall sleeve is formed without any vertically extending ribs.

6 . The insulative container of claim 5 , wherein the container body is injection molded and includes a first thickness at each of the projections and a second thickness between each of the projections, the first thickness being greater than the second thickness.

7 . The insulative container of claim 1 , wherein the shoulder divides the sidewall into a lower portion having the plurality of vertically extending ribs and an upper portion spaced apart from the lower portion, and wherein an outer surface of the sleeve and an outer surface of the upper portion of the side wall are flush with one another in a radial direction relative to the central axis.

8 . The insulative container of claim 1 , wherein the sleeve extends around a lower end of the side wall and onto a lower surface of the floor.
