Plastics container

Abstract

A blow moulded container has a body portion defining a chamber for storing liquid and a neck portion extending from the body portion. The body portion defines a central longitudinal axis and said neck portion is coaxial therewith. The body portion defines an upper shoulder region of curved profile and the neck portion defines a circular cylindrical portion having side walls concentric with and parallel to said central longitudinal axis. The lower end of the cylindrical portion defines a closed loop and has a non-planar intersection with the shoulder region of the body portion.

         21 . A blow-molded container comprising:
 a bottom member;   a plurality of sidewalls including a first pair of opposing parallel sidewalls that are spaced apart by a first dimension, a second pair of opposing parallel sidewalls that are spaced apart by the first dimension, and a third pair of sidewalls that are spaced apart by a second dimension that is different than the first dimension;   a spout for receiving a closure cap;   a handle section proximate to the spout; and   an upwardly converging neck member coupling the sidewalls to the spout having a convex transition section defining a continuous curvature that extends from the sidewalls to the spout.   
     
     
         22 . The blow-molded container of  claim 21 , wherein the convex transition section provides a smooth transition between the sidewalls and the spout. 
     
     
         23 . A blow-molded container comprising:
 a bottom member;   a plurality of sidewalls;   a spout for receiving a closure cap;   a handle section proximate to the spout; and   an upwardly converging neck member coupling the sidewalls to the spout having a convex transition section defining a continuous curvature that extends from the sidewalls to the spout.   
     
     
         24 . The blow-molded container of  claim 23 , wherein the plurality of sidewalls includes at least three pairs of opposing parallel sidewalls. 
     
     
         25 . The blow-molded container of  claim 23 , wherein the convex transition section provides a smooth transition between the sidewalls and the spout. 
     
     
         26 . 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 from the plurality of short sidewalls being disposed between an adjacent pair of long sidewalls from the plurality of long sidewalls, the plurality of short sidewalls including a third pair of sidewalls that is spaced apart by a second dimension that is different than the first 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.
