Abstract
A container bottom for minimizing deformnation. An outer rounded portion, an inner recessed portion, being generally ellipse shaped, and an offset portion extending along the inner recessed portion are adapted to minimize bulging caused by increased ambient temperature and pressure gradients to provide an improved container to store non-liquid goods.
Claims27
A container having a container bottom, the bottom comprising:
- an outer portion, the outer portion having a diameter;
- an inner recessed portion formed within the outer portion, the inner recessed portion being generally ellipse shaped and having an outer ellipse portion and an inner ellipse portion, the inner ellipse portion having a first minor half and a second minor half such that the first minor half and the second minor half are related by a predetermined proportion to the diameter;
- and
- an offset portion, the offset portion being axially offset from and extending along the inner recessed portion, wherein the offset portion and the predetermined proportion of the first minor half, the second minor half and diameter are configured to minimize deformation due to at least one environmental condition.

A container bottom, comprising:
- an outer portion having a radius of curvature;
- an inner recessed portion formed within the outer portion wherein the inner recessed portion is related by a predetermined proportion to the radius of the outer portion, the inner recessed portion being generally ellipse shaped having an outer ellipse portion and an inner ellipse portion, the inner ellipse portion being recessed within the outer ellipse portion;
- and
- an offset portion axially offset from the inner ellipse portion, the offset portion forming a rib extending in the direction of the inner ellipse portion to prevent deformation of the container bottom.
1 more element
A plastic molded container having a top, sidewalls and a bottom which resists deformation during elevated ambient temperatures and pressure gradients, comprising:
- an outer rounded portion having a diameter equivalent to the sidewalls, the outer portion further having a radius of curvature;
- an inner recessed portion formed within the outer rounded portion, the inner recessed portion being generally ellipse shaped having an outer ellipse portion and an inner ellipse portion, the inner ellipse portion being recessed within the outer ellipse portion;
- the inner recessed portion having a first minor half and a second minor half forming a bottom portion wherein the first minor half and the second minor half are related by a predetermined proportion to the diameter;
- and
- an offset portion axially offset from the bottom portion, the offset portion forming a rib extending in the direction of the inner ellipse portion to resist deformation of the bottom.
