Claim:
An applicator/dispenser for dispensing, mixing and/or applying a polymerizable monomeric adhesive or sealant material, comprising: a body portion; an actuator movable relative to the body portion; a cavity in the body portion; a mixing chamber that communicates with the cavity; a bladder coupled to the actuator for providing back and forth communication between the cavity and the mixing chamber, said bladder is closed on one end and disposed at least partially within the cavity, at least a portion of the bladder being flexible; a flow regulating portion; a dispensing opening that communicates with at least one of the cavity and the mixing chamber; a valve that selectively establishes communication between at least two of: the cavity and the mixing chamber; the cavity and the dispensing opening; and the cavity, the mixing chamber and the dispensing opening; and a piercing or breaking portion on the actuator, wherein movement of the actuator relative to the body portion moves the piercing or breaking portion into the cavity, and wherein said repeated actuator movement provides for mixing of polymerizable monomeric adhesive or sealant material prior to dispensing.
