A plastic container lid is adapted for removable attachment to a container. The lid comprises spaced inner and outer peripheral walls defining between them a substantially annular sealing seat for a lid retaining ring carried by the container. The outer wall of the lid defines inwardly-positioned projection means to engage the retaining ring of the container, to facilitate retention of the lid on the container. The outer peripheral wall defines at least one circumferentially extending line of tearing weakness to permit separation of at least some of the inwardly positioned projection means from the remainder of the lid. The lid outer wall defines one or more apertures or recess to provide access to a pry member, to allow prying of the lid away from its retention on a container while causing the line of weakness to tear, permitting removal of the lid and at least partial separation of the projection means from the lid.
