Squeeze operated foam dispenser
First Claim
1. A foam dispenser for use in association with foaming liquids comprising:
- a resiliently deformable bottle having an interior, a neck at one end thereof and an opposed end, the resiliently deformable bottle having an at rest position and an under pressure position;
a mixing chamber proximate to the bottle neck, having a soap inlet and an air inlet and an outlet downstream of the soap inlet and the air inlet whereby the interior of the bottle is in flow communication with the mixing chamber through the soap inlet;
an air tube extending from the air inlet in the mixing chamber into the interior of the bottle and having a distal end proximate to the opposed end of the bottle whereby the mixing chamber is in flow communication with the interior of the bottle through the air tube;
a porous material extending over the outlet of the mixing chamber; and
a self sealing pressure actuated valve positioned in the mixing chamber having the air inlet and the soap inlet on one side thereof and the outlet on the other side thereof, the valve having an open position and a closed position for selectively opening and closing the outlet whereby the valve is closed when the bottle is in the at rest position and opens responsive to the bottle being moved from the at rest position to the under pressure position.

Abstract
A foam dispenser includes a resiliently deformable bottle which has an interior, a neck at one end thereof and an opposed end. The bottle has an at rest position and an under pressure position. A mixing chamber is proximate to the neck and has a soap inlet and an air inlet both upstream of an outlet. The outlet has a porous material thereover. The interior of the bottle is in flow communication with the mixing chamber through the soap inlet. An air tube extends from the mixing chamber into the interior of the bottle and has a distal end proximate to the opposed end of the bottle whereby the mixing chamber is also in flow communication with the interior of the bottle through the air tube. A self sealing pressure actuated valve is for selectively opening and closing the outlet and is responsive to pressure applied to the bottle.
