ABSTRACT A plastic cap is adapted for use with a bottle neck having two spaced grooves formed in the outer surface thereof the upper one of said grooves being spaced from the top edge of the neck so as to define smooth sealing surfaces above, between and below said grooves. The cap has a pair of inwardly directed circumferential beads formed on an inner surface of a thin-walled skirt that depends from a disc-shaped top of the cap. The beads are positioned so that they fit in the grooves when the cap is in place on the neck and form an interference fit with the edges of the grooves to prevent inadvertent removal of the cap. The upper groove is spaced from the upper edge of the neck and the lower groove is spaced from the body portion so that the neck is divided into three separate cylindrical outer surface portions having increasing diameters from the upper most surface portion to the lower most surface portion. Each of the grooves is partially defined by an annular surface intersecting the cylindrical outer surface portion farthest from the body portion at a right angle and a frustoconical surface intersecting the cylindrical outer surface portion closest to the body portion.
