Abstract
A viscous material dispenser, and dispenser system and kit, can include a dispenser without a dispensing tip and one or a plurality of separate dispensing tips that are removably attachable to the dispenser. The dispenser can be used with many different types of viscous material containing capules and cartridges, such as those containing composites, dental cements, glass ionomers and the like. In embodiments, the dispenser can incorporate an integral activator for multi-component composition cartridges, such as glass ionomer cartridges.
Claims22
A viscous material dispenser system, comprising:
- a viscous material dispenser having a barrel with a plunger adapted to extend from a dispensing end of the barrel;
- a first tip assembly for retaining a viscous material container, said first tip assembly being attachable to and detachable from the dispensing end of the barrel of the viscous material dispenser and said first tip assembly containing a first actuator, the first actuator being biased such that an end of the first actuator contacts the plunger when the first tip assembly is attached to the barrel and an opposite end of the first actuator adapted for contacting a viscous material container when a viscous material container is retained in the first tip assembly such that movement of the plunger out of the dispensing end of the barrel causes the first actuator to move toward a dispensing end of the first tip assembly.
A viscous material dispenser kit, comprising:
- a container;
- a viscous material dispenser having a barrel with a plunger adapted to extend from a dispensing end of the barrel of the viscous material dispenser, said dispenser being contained in said container;
- a first tip assembly for retaining a viscous material containing cartridge, said first tip assembly being attachable to and detachable from the dispensing end of the barrel of the viscous material dispenser and said first tip assembly containing a first actuator, an end of the first actuator being adapted to contact the plunger when the first tip assembly is attached to the barrel and an opposite end of the first actuator adapted for contacting a viscous material containing cartridge when a viscous material cartridge is retained in the first tip assembly such that a movement of the plunger out of the dispensing end of the barrel will cause the first actuator to move toward a dispensing end of the first tip assembly, said first tip assembly being contained in said container;
- a second tip assembly for retaining a viscous material containing capsule, said second tip assembly being different from said first tip assembly, and said second tip assembly being attachable to and detachable from the dispensing end of the barrel of the viscous material dispenser and said second tip assembly containing a second actuator, an end of the second actuator being adapted to contact the plunger when the second tip assembly is attached to the barrel and an opposite end of the second actuator adapted for contacting a viscous material containing capsule when a viscous material capsule is retained in the second tip assembly such that a movement of the plunger out of the dispensing end of the barrel will cause the second actuator to move toward a dispensing end of the second tip assembly, the second tip assembly being contained in said container.
1 more element
A viscous material dispenser, comprising:
- means for moving a plunger through a barrel of a viscous material dispenser such that the plunger extends from a dispensing end of the barrel;
- a first means for retaining a viscous material containing capsule, said first means being attachable to and detachable from the dispensing end of the barrel and said first means containing a first actuating means being contacted by the plunger when the first means is attached to the barrel and an opposite end of the first actuating means adapted for contacting a viscous material capsule when a viscous material capsule is retained in the first means such that a movement of the plunger out of the dispensing end of the barrel will cause the first actuating means to move toward a dispensing end of the first tip assembly.
A viscous material dispenser system, comprising:
- a viscous material dispenser having a barrel with a plunger adapted extend from a dispensing end of the barrel;
- the dispenser further having a cooperating pair of handles that can be squeezed together, said cooperating pair of handles comprising a means for activating a viscous material cartridge containing a multi-component composition.
