Apparatus For Forming And Packaging A Delayed Forming Gel
US Patent:
4727914, Mar 1, 1988
Filed:
Sep 12, 1986
Appl. No.:
6/906707
Inventors:

David R. Knowlton - Ipswich MA
Assignee:
The Gillette Company - Boston MA
International Classification:
B65B 104, B65B 304
US Classification:
141105
Abstract:
A method and apparatus for forming and packaging, within a suitable container for the dispensing thereof, an unstable product produced by intimately mixing at least first and second ingredients, the resulting unstable product remaining stable following the mixing of the ingredients for a relatively short period of time under normal ambient conditions, the method including the steps of providing streams of the ingredients, intimately mixing the ingredients in a filling head, ejecting the mixture from the filling head into a container, and sealing the container prior to the elapse of the relatively short period of time. The apparatus generally includes a first metering device for receiving a pressurized supply of the first ingredient and for producing therefrom predetermined dosages thereof, a second metering device for receiving a pressurized supply of the second ingredient and for producing therefrom predetermined dosages thereof, a filling head for simultaneously receiving the predetermined dosages of first and second ingredients, for intimately mixing the dosages and for ejecting the resultant mixture into a container, and actuation apparatus for simultaneously actuating the first and second metering devices when the container is moved to a filling position relative to the filling head.
