First claim

What is claimed is:

1. A closure comprising:
an inner shell comprising:
a. a first upper portion having an outer surface and comprising one or more inner shell ratchets projecting outwardly from the outer surface of the upper portion; and
b. a first lower portion comprising an annular side wall depending downwardly from an outer periphery formed by the first upper portion, the annular side wall of the first lower portion having an outer surface and a first inner surface, the outer surface of the first lower portion comprising one or more inner shell cams projecting outwardly from the outer surface;

an outer shell rotatably housing the inner shell, the outer shell comprising:
a. a second upper portion having an inner surface;
b. a second lower portion comprising an annular side wall depending downwardly from an outer periphery formed by the second upper portion, the annular side wall having a second inner surface comprising:
i. outer shell side wings projecting inwardly from the second inner surface and disposed substantially within a plane for engaging one or more inner shell cams, the plane defining an acute angle with the second inner surface, the side wings bendable outwardly toward the second inner surface wherein the outer shell is movable from a first non-engagement position to a second engagement position relative to the inner shell; and
