STRAW EXTENSION FOR CAPPED CONTAINERS
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.
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.
