ABSTRACT:
In a screw capped bottle, a protuberance (7) cooperates with a notch (9) in a notch-bearing member (10) so that as the cap is screwed on, the protuberance bears on the notch-bearing member and one or both deforms to accommodate the threading movement until the protuberance snaps into the notch to terminate the movement. When screwing the cap off, there is an initial resistance to movement while the protuberance and/or notch-bearing member deforms. The protuberance then snaps out of the notch and the cap may be removed.
