Abstract
An apparatus for making a long lasting foam. The apparatus includes an injection chamber, an expansion chamber and a coiled hose which extends therebetween. The coiled hose includes a plurality of turns. A pressure generating pump is provided to force a stream of a foam solution into the injection chamber where it is mixed with a pressurized stream of air and passed through the injection chamber, through the coiled hose, and through the expansion chamber in order to yield a foam having desirable stability and expansion characteristics.
Claims4
An apparatus for making a long lasting form comprising:
- an injection chamber having an inlet opening and an outlet opening;
- hollow coil means having first and second ends, wherein said coil means comprises two coiled hoses, each of said hoses extending between said injection chamber and said expansion chamber;
- coupling means for connecting said outlet opening of said injection chamber to said first end of said coil means;
- an expansion chamber having an input end and a discharge end, said second end of said coil means being connected to said input end of said expansion chamber, and
- pressure generating means for passing a quantity of a foam solution through said injection chamber, through said coil means, and through said expansion chamber in order to yield a long lasting foam.
