ABSTRACT:
An improved synthetic resinous molded threaded cap for use on necked containers permitting initial press fit installation and subsequent threaded engagement. The cap is provided with a tear seal, an inner surface of which provides mutual engagement of an inwardly projecting rib with a corresponding rib on the container neck. Rupture of the tear seal removes this rib and allows the cap to be threadedly engaged by further axial displacement of the cap upon the neck. The cap may be molded with a feathered free edge to facilitate removal from a mold without damaging the rib.
