There is disclosed a press-on bottle cap which is convertible to a screw reclosure lid. The cap is formed with a circular disc having an integral, downwardly dependent circumferential skirt. The skirt has a raised helical bead on its inside wall which extends an angular increment from 270 to about 400 degrees and a raised circumferential bead located beneath the helical bead and at least one tear line defined by a circumferential band of weakened strength located between the circumferential and helical beads. A tear tab extends from the outer wall of the skirt adjacent the tear line which can be pulled by the user to sever a reclosure lid having the helical bead which can be threaded onto the neck of the bottle to seal its contents. For this purpose, the undersurface of the disc of the cap has a compressible sealing gasket which is engaged by an annular lip of the upper end of the bottle neck.
