Abstract: A hand-held, manually-operated device for dispensing a viscous liquid in conjunction with a wiping action. Downward pressure on a handle causes expression of viscous material through one or more perforations or orifices in a flexible seal which is in abutting relationship with a surface to which the material is to be applied. As the device is slid across such surface the flexible seal provides both a sealing and a wiping action. When downward pressure is released, an expansion gap is created within the device, thereby relieving expression forces.

Abstract: An anti-drip caulking device is provided having a "floating" anti-kickback dog which engages the plunger shaft. When the forward motion of the shaft is stopped, the floating action permits recoil of the plunger and dog until a tension spring is sufficiently stretched to balance the recoil force, or until a mechanical stop is engaged. The floating feature is provided by a tension and compression spring acting in opposition.
