ANTI-LOOSENING SNAP-FIT CAP FOR DISPENSER

摘要

A closure cap snap-fitted to the lower end of a dispenser body is threaded to the neck of a container of fluid to be dispensed and resists back-off or loosening from the container by resisting rotation of the body about the central axis of the container cooperating slip-resistant surfaces are provided between an edge wall of a flexible skirt on the cap and a confronting flange on the body. Rotation of the body is further resisted by the provision of slip-resistant cooperating surfaces between opposing sides of a gasket seal and the respective lower and upper confronting surfaces of the dispenser body and the container neck.
