Abstract
A foam dispenser having a pump assembly includes a liquid pump, an air pump and a common actuation part to simultaneously actuate the liquid pump and the air pump. The pump assembly includes a dispensing channel having a dispensing opening. The pump assembly further includes a porous matrix which contains a dispensate material. A contact surface of the porous matrix is arranged in communication with the dispensing channel, so that foam being formed in the pump assembly and dispensed through the dispensing channel comes into contact with the contact surface to introduce dispensate material released from the porous matrix in the foam.
