Abstract
A dispenser for a pasty or viscous product such as toothpaste is arranged to operate by peristaltic action of an actuator on a deformable member which is backed by an arcuate reaction face. The actuator is mounted for simple pivotal movement to and fro about spigots when a user-engagement member is operated by a user for dispensing and is subsequently released. An integral resilient tongue on the actuator returns the actuator and user-engagement member to their reset positions. For engaging the deformable member, the actuator has a finger portion attached by an integral hinge and arranged to adopt a rigid condition during each forward, dispensing movement of the actuator and a yielding condition during each backward, resetting movement thereof.
