Apparatus for forming and packaging a delayed forming gel

An apparatus for forming and packaging, in a suitable container for the dispensing thereof, a delayed foaming gel, said delayed foaming gel being formed by intimately mixing at least first and second ingredients, said apparatus comprising

• first metering means for receiving a pressurized supply of said first ingredient and for producing therefrom predetermined dosages of said first ingredient;
• second metering means for receiving a pressurized supply of said second ingredient, and for producing therefrom predetermined dosages of said second ingredient;
• filling head means simultaneously receiving said predetermined dosages of said first and second ingredients for intimate mixing said dosage and for ejecting the resultant mixture into a container;
• actuation means for simultaneously actuating said first and second metering means when said container is moved to a filling position relative to said filling head;
• and
• a valve system means for establishing fluid communication between said second metering cylinder and said filling head means only during the passage of said predetermined dosage from said second metering means to said filling head means, said valve system means comprising a needle valve for selectively establishing or blocking flow of said second ingredient into said filling head means and a two-position valve for placing said second metering cylinder in fluid communication with either said needle valve or said second ingredient.

An apparatus for forming and packaging, in a suitable container for the dispensing thereof, a delayed foaming gel, said delayed foaming gel being formed by intimately mixing at least first and second ingredients, said apparatus comprising

• first metering means for receiving a pressurized supply of said first ingredient and for producing therefrom predetermined dosages of said first ingredient, said first metering means including a pressure actuated metering cylinder having a chamber for receiving said first pressurized ingredient and for discharging said predetermined dosages of said first pressurized ingredient into said filling head means, a piston of differential surface area slidingly mounted within said chamber, isolation means for isolating said chamber containing said first pressurized ingredient from the source of said first ingredient;
• second metering means for receiving a pressurized supply of said second ingredient, and for producing therefrom predetermined dosages of said second ingredient;
• filling head means simultaneously receiving said predetermined dosages of said first and second ingredients for intimate mixing said dosage and for ejecting the resultant mixture into a container, said filling head means including valve means for establishing fluid communication between said chamber and said container, a passageway in said filling head means, said piston having a valve face adapted to mate with said passageway and thereby terminate flow of said first ingredient into said filling head means following passage of said predetermined dosage of said first ingredient thereto;
• and
• actuation means for simultaneously actuating said first and second metering means when said container is moved to a filling position relative to said filling head, said actuation means including means for first actuating said isolation means and for thereafter actuating said valve means.
