Abstract:
A fully controlled distribution process for preventing spillages, mis-use and/or mishandling in the unpressurized, gravity feed distribution of chemical products, said process comprising the steps of:A. distributing chemical products in closed and sealed containers incorporating a closed and sealed valve assembly which is non-removably mounted to the container, is openable with only authorized actuators, and is capable of being re-closed and re-sealed, if desired, said valve assembly comprising a collar securely affixed to the container, a housing cooperatively associated with the collar and comprising a plurality of cam tracks formed therein for controlled, cooperating engagement with a valve member by defining a travel path for said valve member, and a valve member positioned within the housing and constructed for cooperative, arcuate, pivoting and axially longitudinal movement relative thereto, said movement being controlled by the engagement of radially extending, fingers in the cam the tracks of the housing;B. securely affixing an adapter to a dilution vessel incorporating an authorized actuator integrally formed thereon and constructed for mating, locking engagement with the valve member of the valve assembly;C. transferring the closed, sealed product bearing container to a user;D. mounting the container bearing the valve assembly onto the adapter by telescopically inserting and interengaging the valve member of the valve assembly with the adapter;E. arcuately pivoting the container and valve assembly relative to the adapter and the dilution vessel in a first direction for causing the valve member of the valve assembly to arcuately pivot relative to the housing in the cam tracks thereof, while simultaneously moving axially from a closed position to an open position;F. dispensing the chemical products from the container through the valve assembly and the adapter into the dilution vessel;G. arcuately pivoting the container and valve assembly relative to the adapter and the dilution vessel in a second direction for causing the valve member of the valve assembly to arcuately pivot relative to the housing in the cam tracks thereof, simultaneously moving axially from the open position to the closed position;H. removing the container with the valve assembly from the adapter for recycling; andI. diluting the concentrated chemical in the dilution vessel by adding water thereto.
