Abstract
An apparatus for producing foam from a liquid mixture.
Claims18
A device, comprising:
- (a) an elastic pliant bottle defining a single bottle chamber having an upper portion and a lower portion;
- (b) an air intake orifice through the bottle in fluid communication with the lower portion of the bottle chamber;
- (c) a first one way valve in fluid communication with the air intake orifice effective for preventing the flow of air out of the bottle chamber through the air intake orifice;
- (d) an aerator within the bottle chamber in sealing fluid communication with the air intake orifice;
- (e) a foam exit port from the bottle chamber in fluid communication with the upper portion;
- and
- (f) a second one way valve in fluid communication with the foam exit port effective for preventing the flow of air into the bottle chamber through the foam exit port;
- (g) wherein (i) air is drawn into the bottle chamber through the air intake orifice and foam is formed when the bottle resumes an original shape after being deformed, and (ii) foam is expelled from bottle chamber through the foam exit port when the bottle is again deformed.

A device, consisting of:
- (a) an elastic pliant bottle defining a bottle chamber having an upper portion, a lower portion and an original shape;
- (b) a foamable liquid within the lower portion of the bottle chamber;
- (c) a port through the bottle in direct fluid communication with only the upper portion of the bottle chamber;
- and
- (d) wherein (i) agitation of the foamable liquid within the bottle chamber will cause the foamable liquid to mix with air and form foam, (ii) squeezing of the bottle will cause the foam to exit the bottle chamber through the port, and (iii) discontinuance of squeezing will allow the bottle chamber to return to the original shape with the suction of air into the bottle chamber.

A device, comprising:
- (a) an elastic pliant bottle defining a bottle chamber having an upper portion, a lower portion and an original shape;
- (b) a foamable liquid within the lower portion of the bottle chamber;
- (c) a port through the bottle in direct unobstructed fluid communication with only the upper portion of the bottle chamber;
- and
- (d) wherein (i) agitation of the foamable liquid within the bottle chamber will cause the foamable liquid to mix with air and form foam, (ii) squeezing of the bottle will cause the foam to exit the bottle chamber through the port, and (iii) discontinuance of squeezing will allow the bottle chamber to return to the original shape with the suction of air into the bottle chamber.

A device, comprising:
- (a) an elastic pliant bottle defining a single bottle chamber having an upper portion and a lower portion;
- (b) a common tube extending through the bottle in fluid communication with the bottle chamber;
- (c) an air intake tube in fluid communication with the common tube and the lower portion of the bottle chamber;
- (d) a first one way valve in fluid communication with the air intake tube effective for preventing the flow of air out of the bottle chamber through the air intake tube;
- (e) an aerator within the lower portion of the bottle chamber in sealing fluid communication with the air intake tube;
- (f) a foam exit tube in fluid communication with the common tube and the upper portion of the bottle chamber;
- and
- (g) a second one way valve in fluid communication with the foam exit tube effective for preventing the flow of air into the bottle chamber through the foam exit tube;
- (h) wherein (i) air is drawn into the bottle chamber through the common tube and the air intake tube so as to form foam when the bottle resumes an original shape after being deformed and (ii) foam is expelled from bottle chamber through the foam exit tube and the common tube when the bottle is again deformed.
