Container and bottom end construction therefor
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.
1. 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 has a second taper angle, wherein the first bottom wall is attached to the lower end of the sidewall;
an outer sleeve having an inner surface and an outer surface, the outer sleeve at least partially surrounding the inner receptacle; and
a second bottom wall, the second bottom wall being attached to a lower end of the outer sleeve;
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 at least a portion of the lower end of the receptacle sidewall is in contact with the second bottom wall.
2. The container of claim 1 , wherein a lower end of the outer sleeve extends beyond and is located below the lowermost edge of the receptacle sidewall.
3. The container of claim 1 , wherein the lowermost edge of the receptacle sidewall contacts the second bottom wall.
4. The container of claim 1 , wherein the first bottom wall includes a downwardly depending annular skirt secured to the receptacle sidewall.
5. The container of claim 4 , wherein the lower end of the receptacle sidewall forms a reverse bend portion at least partially surrounding the annular skirt of the first bottom wall.
6. The container of claim 1 , wherein the second bottom wall includes a downwardly depending annular skirt secured to the inner surface of the outer sleeve.
7. The container of claim 6 , wherein a lower end of the outer sleeve forms a reverse bend portion at least partially surrounding the annular skirt of the second bottom wall.
8. The container of claim 1 , wherein a circumferential gap is defined between the inner receptacle sidewall and the outer sleeve.
9. The container of claim 8 , wherein the circumferential gap is substantially uniform along the upper portion of the inner receptacle sidewall.
10. The container of claim 1 , wherein the first taper angle is between about 0° and about 30° measured from vertical and wherein the second taper angle is about between about −10° and about 2° measured from vertical.
11. The container of claim 1 , wherein the first taper angle is between about 3° and about 5° measured from vertical and wherein the second taper angle is about between about −1° and about 1° measured from vertical.
12. A multi-walled container comprising:
an inner receptacle including a sidewall and a first bottom wall, wherein a frustoconical upper portion of the sidewall has a first taper angle and a lower end of the sidewall has a second taper angle, wherein the first bottom wall is attached to the lower end of the sidewall;
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 lower edge of the receptacle sidewall; and
a second bottom wall, the second bottom wall being attached to a lower end of the outer sleeve;
wherein at least a portion of a lower edge of the lower end of the receptacle sidewall is in contact with the inner surface of the outer sleeve;
wherein at least a portion of the lower end of the receptacle sidewall is in contact with the second bottom wall.
13. The container of claim 12 , wherein the second bottom wall includes a downwardly depending annular skirt secured to the inner surface of the outer sleeve.
14. The container of claim 13 , wherein the lower end of the outer sleeve forms a reverse bend portion at least partially surrounding the annular skirt of the second bottom wall.
