A tamper-evidencing, snap-on, screw-off closure (21) is used with a specially shaped container neck (22). The neck has a neck stretch (28) with multiple neck threads (29) and a locking wall (46) below the neck stretch with a plurality of external teeth (51). The closure has an upper skirt (61) with multiple closure threads (71) which mate with the neck threads and a tamper-evidencing band (70) with a plurality of internal teeth (81) shaped and positioned to engage the external teeth. The teeth are shaped to guide the teeth into side-by-side interengage during axial application of the cap to the neck.
