Abstract

A container is formed to include an interior region and a mouth opening into the interior region. The container includes a floor and a side wall coupled to the floor to define the interior region between the floor and the side wall.

First claim

The invention claimed is:

1. An insulative cup comprising
a body including a sleeve-shaped side wall and
a floor coupled to the body to define an interior region bounded by the sleeve-shaped side wall and the floor, wherein the body comprises a sheet comprising insulative cellular non-aromatic polymeric material configured to provide means for enabling 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 without fracturing the insulative cellular non-aromatic polymeric material so that a predetermined insulative characteristic is maintained in the body,
wherein the plastically deformed first material segment is cellular and the second material segment is cellular,
wherein a first 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 sleeve-shaped side wall and wherein the sleeve-shaped 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 first of the selected regions of the body and cooperate with the upright inner and outer tabs to form the sleeve-shaped side wall,
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 sleeve-shaped 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 the upright outer tab included in the sleeve-shaped side wall, an outer rolled tab coupled to an upper end of the upright inner tab included in the sleeve-shaped 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 region of the body and cooperate with the inner and outer rolled tabs to form the rolled brim,
wherein a third 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 sleeve-shaped 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 sleeve-shaped side wall to form the interior region and wherein the floor mount includes a web-support ring coupled to the lower end of the sleeve-shaped side wall and configured to provide the second material segment having the second density in the third 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 third of the selected regions of the body,
wherein a fourth 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 floor-retaining flange of the floor mount, the floor-retaining flange includes an alternating series of upright thick and thin staves arranged in side-to-side relation to extend upwardly from the web toward the interior region bounded by the sleeve-shaped side wall and the floor, a first of the upright thick staves is configured to include a right side edge extending upwardly from the web toward the interior region, a second of the upright thick staves is configured to include a left side edge arranged to extend upwardly from the web 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, the first of the upright thin staves is configured to provide the first material segment in the fourth of the selected regions of the body, and the first of the upright thick staves is configured to provide the second material segment in the fourth of the selected regions of the body.

2. The insulative cup of claim 1 , wherein the upright fence includes an upright left side edge and an upright right side edge arranged to lie in spaced-apart confronting relation to the upright left side edge and the upright outer tab is configured to have the first density and mate with the upright inner tab to establish a bridge arranged to interconnect the upright left and right side edges of the upright fence and formed of plastically deformed material having the first density.

3. The insulative cup of claim 2 , wherein the upright fence has an inner surface bounding a portion of the interior region and an outer surface facing away from the interior region and surrounding the inner surface of the upright fence and cooperating with the inner surface of the upright fence to define a first thickness therebetween, the upright inner tab includes an inner surface bounding a portion of the interior region and an outer surface facing toward the upright outer tab, the upright outer tab includes an inner surface facing toward the interior region and mating with the outer surface of the upright inner tab to define the interface between the upright inner and outer tabs, and the upright outer tab further includes an outer face facing away from the upright inner tab, the inner and outer surfaces of the upright inner tab cooperate to define a second thickness therebetween that is about half of the first thickness, and the inner and outer surfaces of the upright outer tab cooperate to define a third thickness that is about half of the first thickness.

4. The insulative cup of claim 1 , wherein each of the web and the web-support ring has an annular shape.

5. The insulative cup of claim 1 , wherein each of the floor-retaining flange, the web, and the web-support ring includes an inner layer having an interior surface mating with the floor and an overlapping outer layer mating with an exterior surface of the inner layer.

6. The insulative cup of claim 1 , wherein the floor includes a horizontal platform bounding a portion of the interior region and a platform-support member coupled to the horizontal platform and arranged to extend downwardly away from the interior region into a space provided between the floor-retaining flange and the web-support ring to mate with each of the floor-retaining flange and the web-support ring.

7. The insulative cup of claim 6 , wherein the platform-support member h
