Abstract
Abstract Container and closure cap assembly comprises container with open top portion and closure cap for sealing top portion of container. Closure cap has lower portion secured to top portion of container and upper portion separated from lower portion by weakened line of connection. Upper portion of closure cap after separation from lower portion thereof serves as removable closure for container top. Projections on upper portion of closure cap and exterior of container top cooperate with each other to seal container top after upper portion of closure cap is separated from lower portion. Prior to separation projections on closure cap are positioned adjacent to but out of direct contact with projections on container top.
