ABSTRACT:
There is disclosed an elbow cover formed of a flexible thin sheet having a bistable configuration with: (1) an open stacking shape having an interior concavity and exterior convexity formed with a substantially ellipsoidal central portion and opposite, laterally projecting, substantially parabolic hyperboloidal ears; and (2) a closed, stable configuration forming a tubular elbow shape with the ears folded inwardly, completing the tubular ends of the elbow shape. The elbow cover is characterized by an unstable configuration assumed by compression of the closed tubular shape between its opposite outside tubular edges whereby the elbow shape flexes and spreads open, laterally separating the ears in a position permitting a one-handed application of the cover to an insulated elbow joint of tubular conduits.
