Publication number: 20150329252Abstract: A dispenser comprising a body with an outlet, and a closure for the outlet. The closure and the body are pivotally movable relative to each other between an open position in which the outlet is open and a closed position in which the closure closes the outlet. The closure and the body are adapted for locking engagement with each another in the closed position. The closure has a locking member for locking and unlocking the closure and the body in the closed position. A force applied on the locking member for unlocking urges the closure toward the open position. The dispenser preferably facilitates the application of a material to be dispensed to a desired location.Type: ApplicationFiled: July 28, 2015Publication date: November 19, 2015Inventors: Alexander Walter, Marc Peuker, Bruce R.

Publication number: 20150125827Abstract: An apparatus for dispensing a viscous dental paste that includes a barrel member, a dispensing tip, and a platform. The barrel defines a chamber for containing a viscous material. The dispensing tip extends from the barrel member to a dispensing end and defines a passageway open to the chamber. The dispensing end forms an outlet opening open to the passageway and circumscribed by a continuous wall defining an interior surface and an exterior surface. The platform projects from the dispensing end and defines opposing first and second major faces. The first major face is aligned with the outlet opening. The second major face is contiguous with a section of the exterior surface. Viscous material is dispensed from the chamber and onto the platform as a ribbon or sheet.Type: ApplicationFiled: November 3, 2014Publication date: May 7, 2015Inventors: Christopher J. Claypool, Bruce R. Broyles

Publication number: 20100167231Abstract: The invention includes a piston having a piston body (1) and front seal for sealing the gap between the side wall of the piston body and the wall of a chamber within which the piston and a material are disposed in a conventional manner. The front seal (5) has a leading edge (6) included angle (A) as defined below, and a trailing edge (7) included angle (B) that is smaller than the leading edge included angle. By the appropriate selection of these two angles, the force required to move the piston (and thus the material) is optimized, the force required to move the piston (and thus the material) is optimized, which results in a more useful dispenser than conventional syringe-type dispensers. These and other features of the present invention are described in greater detail below.Type: ApplicationFiled: November 21, 2007Publication date: July 1, 2010Inventors: John W. Dubbe, Gioacchino Raia, Hecht Reinhold, Manfred Ludsteck, Bruce R. Broyles, Henry C. Gydesen, Dirk Albrecht, Helmut Pauser
