Patent ID: 7798371

Claim:
A dispenser comprising: a housing, a dispensing mechanism including a slide element mounted to the housing for cyclical reciprocal movement in a linear direction about a straight longitudinal axis relative the housing between an extended position and a retracted position to dispense a flowable material, a lever member pivotally mounted to the housing for pivotal movement about a pivot axis, the pivot axis substantially normal to the longitudinal axis, the housing having a camming surface disposed at a constant radius from the pivot axis, a flexible bridge member having a first end, a second end, a first side edge, a second side edge, and a cammed face, the bridge member coupled to the housing between the slide element and the lever with the first end of the bridge member engaging the lever, the second end of the bridge member engaging the element, and the cammed face of the bridge member urged into sliding engagement with the camming surface of the housing such that the bridge member between its first end and second end is deformed to assume the shape of the camming surface of the housing where the cammed face of the bridge member engages the camming surface of the housing, the bridge member slidable with the cammed face of the bridge member in engagement with the camming surface of the housing between: (a) a first position in which the slide element is in the extended position and the lever is in a first rotational position relative the pivot axis and, (b) a second position in which the slide element is in the retracted position and the lever is in a second rotational position rotated from the first rotational position about the pivot axis.
