ABSTRACT:
A dynamic joint connection is provided between the neck region of a base and the engagement end of a cap. The neck region comprises a reduced diameter end of the base which is offset from the base outer wall by a flat ledge. Located above the ledge a first axial distance, is a first convex rib. The interior surface of the cap engagement end is provided with a cap rib which is located a third axial distance above its abutment end. The third distance will locate the cap rib against the first rib on the down-sloping portion of its surface when the cap abutment end is in contact with the neck region ledge. The compressive force of the cap ring against the first rib will cause the abutment end to be biased downwardly against the ledge. This unstable condition creates a dynamic connection that maintains its integrity throughout rough handling, internal pressures and varying ambient conditions. The neck region can include a second rib. This rib will be in sealing contact with an inner cap wall when the cap rib and first rib are engaged. The spaced-apart sealing areas create a dead air chamber therebetween and provide an additional obstacle to the escape of volatile materials or dusts that may emanate from the materials stored within the base.
