Abstract
A container may include a sidewall. A container may include a base with a first portion and a second portion. The second portion may include a plurality of lobes with a thickness greater than a thickness of the first portion. The plurality of lobes may be formed by impregnating plastic with a foaming agent that may cause the plastic to foam during manufacturing.
Claims25
A unitary fluid container comprising:
- a sidewall;
- and
- a base comprising:
- a first portion comprising a first thickness;
- a second portion comprising a second thickness,
- wherein the sidewall is molded to the base and extending from an edge of the base,
- wherein the sidewall and the base comprise expanded plastic, and
- wherein the expanded plastic at a location of the second portion of the base is expanded more than the expanded plastic at a location of the first portion of the base so the second thickness is greater than the first thickness.

An expanded plastic fluid container comprising:
- an expanded plastic sidewall;
- and
- an expanded plastic base, the expanded plastic sidewall is molded to the expanded plastic base and extending from an edge of the expanded plastic base, the expanded plastic base comprising:
- a first portion comprising a first thickness;
- a second portion comprising a plurality of lobes having a second thickness,
- wherein expanded plastic at the second portion of the expanded plastic base is expanded more than expanded plastic at the first portion of the base so the second thickness is greater than the first thickness such that when the expanded plastic base of the expanded plastic container is placed on a surface the plurality of lobes contact the surface.
3 more elements
A unitary fluid container comprising:
- a sidewall;
- and
- a base extending between an inner surface and an outer surface, the sidewall is molded to the base and extending from an edge of the base, the base comprising:
- a first portion comprising a first thickness between the inner surface and the outer surface;
- a second portion comprising a plurality of lobes extending radially outward from a center of the base to the edge of the base, the plurality of lobes having a second thickness between the inner surface and the outer surface,
- wherein the inner surface of the base is substantially planar, wherein the sidewall and the base comprise expanded plastic, and
- wherein the expanded plastic at a location of the second portion is expanded more than the expanded plastic at a location of the first portion so the second thickness is greater than the first thickness such that when the base of the container is placed on a surface the plurality of lobes contact the surface and the first portion does not contact the surface.
