Abstract
An improved lightweight container incorporates a thinner wall structure in an essentially octagonal container having a bottom member, a plurality of sidewalls, a spout, an upwardly converging neck member coupling the sidewalls of the spout, a handle molded into the container and a radiused transiting section between the sidewalls and the spout which eliminates weakened corner sections and improves overall strength to weight ratios.
Claims20
A blow-molded container comprising:
- a bottom member;
- a plurality of sidewalls including a first pair of opposing parallel sidewalls having a first width, a second pair of opposing parallel sidewalls having the first width, a third pair of opposing parallel sidewalls having a second width and a fourth pair of opposing parallel sidewalls having a third width;
- a spout for receiving a closure cap;
- a handle section proximate to the spout;
- a sidewall upper limit defined by one or more sidewalls from the plurality of sidewalls;
- and
- a curved transition that is formed between the sidewall upper limit and the spout, wherein the curved transition defines a curvature that extends continuously from the sidewall upper limit to the spout to provide a smooth transition between the sidewall upper limit and the spout.

A blow-molded container comprising:
- a bottom member;
- a plurality of long sidewalls, each long sidewall of the plurality of long sidewalls being substantially planar, the plurality of long sidewalls including a first pair of opposing parallel sidewalls that is spaced apart by a first dimension, and a second pair of opposing parallel sidewalls that is spaced apart by the first dimension;
- a plurality of short sidewalls, each short sidewall of the plurality of short sidewalls being substantially planar, the plurality of short sidewalls including a third pair of opposing parallel short sidewalls spaced apart by a second dimension that is different than the first dimension and a fourth pair of opposing parallel short sidewalls spaced apart by a third dimension that is different than the first dimension and the second dimension;
- a spout for receiving a closure cap;
- a handle section proximate to the spout;
- a sidewall upper limit defined by one or more long sidewalls from the plurality of long sidewalls and one or more short sidewalls from the plurality of short sidewalls;
- and
- a curved transition that is formed between the sidewall upper limit and the spout, wherein the curved transition defines a curvature that extends continuously from the sidewall upper limit to the spout to provide a smooth transition between the sidewall upper limit and the spout.

A blow-molded container comprising:
- a bottom member;
- a plurality of sidewalls including a first pair of opposing parallel sidewalls having a first width, a second pair of opposing parallel sidewalls having the first width, a third pair of opposing parallel sidewalls having a second width and a fourth pair of opposing parallel sidewalls having a third width;
- a spout portion configured for engagement with a closure cap;
- a handle section proximate to the spout portion;
- and
- a curved transition that is formed between one or more sidewalls from the plurality of sidewalls and the spout, wherein the curved transition defines a curvature that extends from the one or more sidewalls from the plurality of sidewalls to the spout to provide a smooth transition between the one or more sidewalls from the plurality of sidewalls and the spout.
