Abstract: A pump dispenser has a large ergonomic actuator designed to ergonomically deliver a composition to a substrate in the consumer's hand without the consumer having to pick up the pump dispenser. The ergonomic design allows the composition to be delivered in a proper aspect ratio to the substrate. The composition can be delivered in such a way that the composition is not aerosolized into the air or delivered to an unintended surface. The method of delivery can be made intuitive to the consumer by providing an actuator skirt that suggests the pumping mechanism or by providing a depiction of a hand or substrate over the pump dispenser. The pump dispenser is also useful for compositions or substrates that are not stable together.

Abstract: A dispenser comprises a liquid piston and a gas piston coupled for movement. The pistons are mounted for movement relative to one another to define a mixing chamber therebetween. An actuator simultaneously moves the pistons in a first direction such that the air piston delivers air from an air chamber to the mixing chamber and the liquid piston delivers a liquid from a liquid chamber to the mixing chamber where the air and liquid are mixed in the mixing chamber to create a foam. Movement of one of the air piston and the liquid piston is stopped such that the pistons move relative to one another such that only air is delivered to the mixing chamber. The movement of the pistons in a second direction draws residual foam from a delivery tube and delivers the residual foam to the air chamber.
