Abstract: A foam pump independent of spring sealing includes a gland, a connecting part, a moving part, an outer cover, an inner core, a piston, a middle sheath, a piston seat, an outer case, a bead, a spring and a straw. The gland can rotate relative to the outer cover, and is connected with the moving part located in the gland; the connecting part is fixed in an inner cavity of the gland; one end of the inner core away from the moving part extends into an inner cavity of the piston, and is movably connected with a sealing assembly on the piston along with the piston seat. The foam pump independent of spring sealing can prevent the liquid from being squeezed, and can also increase the service life of the spring and improve product competitiveness and user experience.

Abstract: A pump dispenser having a bottle with a neck and a pump assembly. The pump assembly includes an actuator, a closure connected to the actuator and coupled to the neck of the bottle, a dip tube, and a dual chamber pump. The dual chamber pump includes a piston assembly, a sealing cap, and a housing, which includes a pump chamber, a storage chamber having a cavity, and a core. The sealing cap is rigidly connected to the core and closes the storage chamber at a lower portion such that the substance to be released remains stored in the storage chamber cavity. When the actuator is pushed down for a first time by a user, a piston assembly moves to push down a connecting stem, which pushes down the sealing cap to open the storage chamber for releasing the substance contained in the storage chamber from the bottle.
