Abstract
A molten wax applicator for use in building up wax patterns and forms, particularly in dental applications. A hollow, heated stock provides a reservoir for holding molten wax. A nozzle having a wax-dispensing tip connects to the stock. A conduit through the nozzle interconnects the reservoir with the dispensing tip. A valve raceway intercepts the conduit. A valve incorporating resilient, polymeric conduit-sealing elements works in the raceway. A valve actuator with associated lock is connected to the valve for shifting it between open and closed positions permitting, in the open position, controlled dropwise or continuous flow of molten wax to the work.
Claims13
A molten wax applicator comprising:
- a) a hollow stock providing a reservoir for holding molten wax,
- b) heating means in operative contact with the reservoir for maintaining the wax in molten condition,
- c) connected to the stock a heat conductive nozzle having a wax-dispensing tip,
- d) a conduit through the nozzle interconnecting the reservoir with the dispensing tip, and
- e) positioned in the tip for controlling the flow of molten wax through the conduit, valve means incorporating as a conduit-sealing component a component fabricated from a resilient polymeric material which is chemically resistant to the action of hot molten wax and which melts at a temperature of from 150.degree.-480.degree. F.
