A bladder-type dispensing pump (100) comprises a push nozzle (110) and a container cap (120), said nozzle (110) and cap (120) being interconnected. The push nozzle (110) is provided with a bladder portion (111). The bladder portion (111) is able to deform such that the volume of the internal cavity thereof may change. The bladder-type dispensing pump (100) is further provided with an elastic return mechanism. A portion of the elastic return mechanism is connected to or in contact with the bladder portion (111). When the bladder portion (111) is depressed so as to deform, the elastic return mechanism deforms with it, and when pressure acting on the bladder portion (111) is removed, the elastic return mechanism returns to its non-deformed state, causing the bladder portion (111) to reset.
