Multifunctional cap for a storage container
First Claim
Patent Images
1. A closure cap of monolithic construction for a tubular container, said cap comprising:
- a) a collar portion of circular configuration with respect to a center axis, bounded by first and second extremities lying in parallel planes spaced apart in orthogonal relationship to said axis, an inner surface directed toward said axis and having a circular cylindrical contour with respect to said axis, and an opposed outer surface comprised of a first band portion convergently tapered toward said axis in the direction of said first extremity, and a second band portion convergently tapered toward said axis in the direction of said second extremity, said first and second band portions meeting in a circular apogee ridge representing the maximum diameter of said outer surface, andb) a flange transversely disposed to said axis and defining a circular aperture centered upon said axis and having a diameter smaller than the diameter of said inner surface, said flange having a perimeter directed outwardly from said axis and extending beyond said outer surface.

Abstract
A closure cap for a tubular container is formed as a monolithic plastic structure having a collar portion of circular configuration with respect to a center axis, and a flange transversely disposed to the axis and defining a circular aperture centered upon the axis. The collar portion has a doubly tapered outer surface which facilitates frictionally gripping engagement with the interior of the container or engagement with another cap of smaller size. Dual caps having multi-functional features are formed by the frictional interengagement of two caps.
