Abstract
Official abstract text for this publication.
A method of molding a personal care product, a manifold, and a cosmetic product molding apparatus are provided. In one embodiment, the method of molding a personal care product comprises: moving a material through a temperature controlled manifold, opening one or more injection valves between the temperature controlled manifold and one or more mold cavities, injecting the material at a controlled pressure into the one or mold cavities in a closed position to form one or more articles, closing the one or more injection valves between the temperature controlled manifold and one or more mold cavities after injecting the material into the one or more mold cavities, opening the one or more mold cavities, and removing the one or more articles from the one or more mold cavities.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of molding a personal care product comprising: combining in a holding container a first phase and a second phase of material to form a multiphase material; pumping the multiphase material from the holding container to a recirculation tank; continuously moving the multiphase material from the recirculation tank through a temperature controlled manifold; while continuously moving the multiphase material through the temperature controlled manifold: opening one or more injection valves between the temperature controlled manifold and one or more mold cavities; injecting the multiphase material at a controlled pressure into the one or more cavities in a closed position to form one or more articles; closing the one or more injection valves between the temperature controlled manifold and one or more mold cavities after injecting the multiphase material into the one or more mold cavities; opening the one or more mold cavities; and removing the one or more articles from the one or more mold cavities. 2. The method of claim 1 , further comprising: opening a recirculation valve to the temperature controlled manifold. 3. The method of claim 2 , further comprising: after opening the one or more injection valves, closing the recirculation valve. 4. The method of claim 1 , further comprising: cooling the multiphase material within the one or more mold cavities to form the one or more articles prior to removing the one or more articles from the one or more mold cavities. 5. The method of claim 1 , wherein said injecting the multiphase material at the controlled pressure comprises continuously pumping the multiphase material into and out of the temperature controlled manifold. 6. The method of claim 1 , further comprising: recirculating the multiphase material through a recirculation tank. 7. The method of claim 1 , further comprising: heating the multiphase material prior to moving the multiphase material through the temperature controlled manifold. 8. The method of claim 1 , further comprising: heating the multiphase material between the holding container and the recirculation tank. 9. The method of claim 1 , further comprising: wherein the first phase comprises a first hydrophobic phase and the second phase comprises a second hydrophilic phase. 10. The method of claim 1 , further comprising: adding more of the multiphase material to the holding container or to a return line of a recirculation loop, wherein the recirculation loop fluidly connects the temperature controlled manifold and the recirculation tank.
