Straw extension for capped containers

Abstract

A straw extension is preferably a monolithic elastic body which includes a connector head which may attach to a straw. Extending from the connector head is a main body. The main body has a complex curvilinear form which is semi-helical. This complex for allows manufacture using normal methods, but collapses more easily and has reduced chance of being blocked during collapse.

What is claimed is: 
     
         1 . An extension for a straw useful in beverage containers, comprising:
 a connector head including a straw opening, and   a main body extending from said connector head and having an inlet opening, said inlet opening and said straw opening being connected by a continuous cavity having a centerline, and said main body being formed of an elastic material, wherein the improvement comprises;   said main body having a complex curvilinear and semi-helical form which collapses under axial force.   
     
     
         2 . An extension as in  claim 1 , wherein said connector head and said main body are a monolithic unit. 
     
     
         3 . An extension as in  claim 1 , wherein said complex curvilinear and semi-helical form are created by projecting a helical reference line upon a teardrop-shaped solid centered upon a linear extension projecting from a centerline of said connector head. 
     
     
         4 . An extension as in  claim 3 , wherein said connector head and said main body are a monolithic unit.
