Foaming cartridge for use with a foam pump, refill unit or foam dispenser includes a housing and a foaming stage disposed within the housing. The foaming stage includes two or more mix media located within the foaming stage. At least two of the mix media are sponges and the sponges have different porosities.

A soap dispenser including a rigid cartridge, an inverted dispensing pump, a collar carrying a lever for actuating the pump, and a venting system for equalizing the air pressure in the rigid cartridge, wherein the rigid cartridge and the collar cooperate to removably attach the soap dispenser to a wall-mounted bracket, and further wherein at least the rigid cartridge is disposable and can be made of a recyclable and/or biodegradable material.

The present disclosure relates to a foam dispenser and a hand sanitizer dispenser. The foam dispenser comprises housing, liquid supply unit, first liquid outlet passage, second liquid outlet passage, and foaming assembly. The housing is provided with transition chamber, inlet and outlet both communicating with the transition chamber. The foaming assembly is detachably disposed in the transition chamber. Liquid outlet of the liquid supply unit communicates with one end of first liquid outlet passage, and the other end of first liquid outlet passage communicates with inlet. The outlet communicates with one end of the second liquid outlet passage, such that a liquid-gas mixture provided by liquid supply unit sequentially flows through first liquid outlet passage, inlet, foaming assembly, outlet, and second liquid outlet passage to be dispensed. The technical solution provided by the present disclosure makes it convenient for users to repair the foaming component of the hand sanitizer dispenser.

An exemplary foam dispenser includes a housing, a reservoir for holding a foamable liquid, and a pump located below the reservoir. The pump includes a liquid pump chamber, two or more air pump chamber and a manifold. The manifold includes a liquid outlet port, a liquid outlet valve and an air outlet port. An elongated liquid dispensing conduit in fluid communication with the liquid outlet port and an elongated air dispensing conduit in fluid communication with the air outlet port are also included. A mixing chamber having a mixing chamber liquid inlet, a mixing chamber air inlet, and a foam outlet is provided. The mixing chamber is located remotely from the sequentially operated multi-diaphragm pump. The elongated liquid dispensing conduit is in fluid communication with the mixing chamber liquid inlet and the elongated air dispensing conduit is in fluid communication with the mixing chamber air inlet.
