Abstract

Claims (28)

1. An insulative container comprising

a body including a side wall and

a floor coupled to the body to define an interior region bounded by the side wall and the floor,

wherein the body comprises a sheet comprising insulative cellular non-aromatic polymeric material that has localized plastic deformation in at least one selected region of the body to provide a plastically deformed first material segment having a first density located in a first portion of the selected region of the body and a second material segment having a second density lower than the first density located in an adjacent second portion of the selected region of the body,

wherein the body includes a floor mount coupled to a lower end of the side wall and to the floor to support the floor in a stationary position relative to the side wall to form the interior region and the floor mount includes an alternating series of upright thick and thin staves arranged in side-to-side relation, a first of the upright thin staves is configured to provide the first material segment in a first of the selected regions of the body, and a first of the upright thick staves is configured to provide the second material segment in the first of the selected regions of the body.

2. The insulative container of claim 1 , wherein a second of the selected regions of the body in which localized plastic deformation is enabled by the insulative cellular non-aromatic polymeric material is in a rolled brim included in the body and coupled to an upper end of the side wall to lie in spaced-apart relation to the floor and to frame an opening into the interior region and wherein the rolled brim includes an inner rolled tab configured to provide the first material segment in the second of the selected regions of the body and coupled to an upper end of an upright outer tab included in the side wall, an outer rolled tab coupled to an upper end of an upright inner tab included in the side wall and to an outwardly facing exterior surface of the inner rolled tab, and a rolled lip arranged to interconnect oppositely facing side edges of each of the inner and outer rolled tabs and configured to provide the second material segment having the second density in the second of the selected regions of the body and cooperate with the inner and outer rolled tabs to form the rolled brim.

3. The insulative container of claim 2 , wherein the inner rolled tab and the outer rolled tab cooperate to provide a first brim thickness, the rolled lip has a second brim thickness, and the first brim thickness is about equal to the second brim thickness to cause a smooth transition to be formed at a transition point where the inner rolled tab and the outer rolled tab overlap one another and couple to the rolled lip.

4. The insulative container of claim 3 , wherein the first density is greater than about 0.3 g/cm 3 and the second density is from about 0.15 g/cm 3 to about 0.2 g/cm 3 .

5. The insulative container of claim 3 , wherein the plastically deformed first material segment is cellular and the second material segment is cellular.

6. The insulative container of claim 5 , wherein the first material segment has a predetermined insulative characteristic.

7. The insulative container of claim 6 , wherein the first density is from about 0.3 g/cm 3 to about 0.4 g/cm 3 and the second density is from about 0.15 g/cm 3 to about 0.2 g/cm 3 .

8. The insulative container of claim 3 , wherein the floor mount includes a support ring coupled to the lower end of the side wall and a floor-retaining flange coupled to the floor and arranged to be surrounded by the support ring and the floor-retaining flange includes the alternating series of upright thick and thin staves.

9. The insulative container of claim 8 , wherein the floor mount further includes a web arranged to interconnect the floor-retaining flange and the web-support ring.

10. The insulative container of claim 8 , wherein the first of the upright thick staves is configured to include a right side edge extending upwardly toward the interior region, a second of the upright thick staves is configured to include a left side edge arranged to extend upwardly toward the interior region and lie in spaced-apart confronting relation to the right side edge of the first of the upright thick staves, and a first of the upright thin staves is arranged to interconnect the right side edge of the first of the upright thick staves and the left side edge of the second of the upright thick staves and to cooperate with the left and right side edges to define therebetween a vertical channel.

11. The insulative container of claim 10 , wherein the first density is from about 0.3 g/cm 3 to about 0.4 g/cm 3 and the second density is from about 0.15 g/cm 3 to about 0.2 g/cm 3 .

12. The insulative container of claim 1 , wherein a second of the selected regions of the body in which localized plastic deformation is enabled by the insulative cellular non-aromatic polymeric material is in a floor mount included in the body and coupled to a lower end of the side wall to lie in spaced-apart relation to the rolled brim and to the floor to support the floor in a stationary position relative to the side wall to form the interior region and wherein the floor mount includes a web-support ring coupled to the lower end of the side wall and configured to provide the second material segment having the second density in the second of the selected regions of the body, a floor-retaining flange coupled to the floor and arranged to be surrounded by the web-support ring, and a web arranged to interconnect the floor-retaining flange and the web-support ring and configured to provide the first material segment having the first density in the second of the selected regions of the body.

13. The insulative container of claim 12 , wherein the first density is greater than about 0.3 g/cm 3 and the second density is from about 0.15 g/cm 3 to about 0.2 g/cm 3 .

14. The insulative container of claim 1 , wherein a second of the selected regions of the body in which localized plastic deformation is enabled by the insulative cellular non-aromatic polymeric material is in the side wall and wherein the side wall includes an upright inner tab arranged to extend upwardly from the floor and configured to provide the first material segment having the first density in the first of the selected regions of the body, an upright outer tab arranged to extend upwardly from the floor and 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 interior region and configured to provide the second material segment having the second density in the second of the selected regions of the body and cooperate with the upright inner and outer tabs to form the side wall.

15. The insulative container of claim 1 , wherein the first density is from about 0.3 g/cm 3 to about 0.4 g/cm 3 .
