Abstract
A container with a deep recessed bottom end construction is provided. The container includes an inner receptacle having a sidewall and a bottom wall defining an interior volume within the receptacle. The container further includes an outer sleeve wrapped around the inner receptacle with a lower end extending below the lower edge of the receptacle to form a deep bottom recess within a lower portion of the container. The lower end of the receptacle sidewall has a taper angle that is different from a taper angle of an upper portion of the sidewall. The lower end of the receptacle sidewall may engage or contact the inner surface of the outer sleeve. The outer sleeve may include reverse bend and/or a second bottom wall onto which a lower end of the receptacle may sit.
Claims11
A multi-walled container comprising:
- an inner receptacle including a sidewall, an uppermost edge, a lowermost edge, and a first bottom wall, wherein an upper portion of the sidewall extending below the uppermost edge has a first taper angle and a lower end of the sidewall extending above the lowermost edge of the receptacle has a second taper angle;
- and
- an outer sleeve having an inner surface and an outer surface, the outer sleeve at least partially surrounding the inner receptacle;
- wherein at least a portion of the lowermost edge of the lower end of the receptacle sidewall is in contact with the inner surface of the outer sleeve;
- wherein a lower end of the outer sleeve extends beyond and is located below the lowermost edge of the receptacle sidewall;
- wherein the lower end of the outer sleeve comprises a reverse bend portion having an upper terminal edge;
- wherein at least a portion of the lowermost edge of the lower end of the receptacle sidewall is in contact with the upper terminal edge of the reverse bend.

A multi-walled container comprising:
- an inner receptacle including a sidewall, an uppermost edge, a lowermost edge, and a first bottom wall, wherein a frustoconical upper portion of the sidewall extending below the uppermost edge has a first taper angle and a lower end of the sidewall extending above the lowermost edge of the receptacle has a second taper angle;
- and
- an outer sleeve having an inner surface and an outer surface, the outer sleeve at least partially surrounding the inner receptacle and having a lower end that extends beyond and is located below the lowermost edge of the receptacle sidewall;
- wherein at least a portion of the lowermost edge of the lower end of the receptacle sidewall is in contact with the inner surface of the outer sleeve;
- wherein the lower end of the outer sleeve comprises a reverse bend portion having an upper terminal edge, and wherein at least a portion of the lowermost edge of the lower end of the receptacle sidewall is in contact with the upper terminal edge of the reverse bend of the outer sleeve.

A method of forming multi-walled container comprising:
- obtaining an inner receptacle including a sidewall, an uppermost edge, a lowermost edge, and a bottom wall, wherein an upper portion of the sidewall extending below the uppermost edge has a first taper angle;
- forming a lower end of the receptacle sidewall such that the lower end of the sidewall extending above the lowermost edge of the receptacle has a second taper angle different from the first taper angle;
- obtaining an outer sleeve having an inner surface and an outer surface;
- forming a reverse bend portion into a lower end of the outer sleeve, the reverse bend portion having upper terminal edge;
- combining the outer sleeve and inner receptacle such that at least a portion of the lowermost edge of the lower end of the receptacle sidewall is in contact with the inner surface of the outer sleeve;
- and
- positioning the outer sleeve relative to the inner receptacle such that at least a portion of the lowermost edge of the lower end of the receptacle sidewall is in contact with the upper terminal edge of the reverse bend of the outer sleeve.
