A two piece combination of a container and cap, wherein the neck portion of the container and the flange of the cap have interengaging locking elements for securing the pieces together. A generally cylindrical flexible wall is an extension of the container neck, and terminates in annular free end perpendicular to the container neck. This annular free end engages an internally beveled surface of the cap, such that when the locking elements are engaged, the annular free end is deflected radially inwardly to provide an axially biasing force maintaining the elements engaged and also providing a seal between that member and the cap beveled surface.
