ABSTRACT:
An assembly for mixing and dispensing preparations such as dental cements includes a capsule and a lever actuated dispensing device. The capsule is received in a first orientation of the dispensing device for initial movement of a piston of the capsule to combine two components in a mixing chamber of the capsule. The capsule is received in a second orientation when dispensing of the components is desired. The capsule includes flanges engageable with one or more retention members of the dispensing device, and the flanges are positioned to substantially utilize the mechanical advantage provided by the dispensing device regardless of whether the capsule is in the first orientation or in the second orientation. The flanges are also arranged to substantially prohibit bursting of the capsule when the components are discharged from the mixing chamber, and essentially preclude dispensing of the components when the capsule is in the first orientation.
