The flat pump may include an internal reservoir, a valve, a valve conduit and a vortex chamber wherein fluid from the reservoir may be pumped through the valve, along the valve conduit, and into the vortex chamber. An atomized liquid stream, spray, or mist formed in the vortex chamber may be expelled from the flat pump.

Abstract: A low height precompression pump having a piston with a lower outwardly flaring lip seal and an inwardly flaring lip seal rimming a central aperture of the piston, and which may include a first elastic member housed in the cylinder and a second elastic member having an upper bearing point applied directly on the plunger rod above an upper retention cover.

Abstract: A pump having a sealing mechanism including (a) a main body having a first surface, (b) an attachment body with member to attach to a bottle neck, (c) an inlet valve, (d) a second surface where both surfaces define a pumping chamber, and (e) a discharge valve, where both surfaces are adapted to perform a relative movement therebetween causing the pumping of a liquid. The attachment body is connected to the main body for relative displacement between an open position and a closed position and includes a projection which, when the attachment body and the main body are in the closed position, prevents the second surface from performing the relative movement.

Abstract: A pushbutton for a pump or valve for dispensing fluid substances contained in a container on which the pump is mounted. The main portion of the pushbutton has a substance dispensing nozzle and elements for securely retaining said main portion on the pump or on a body rigid therewith. The pushbutton also has an upper or movable portion with a seat for sealedly housing the free end of the pump stem. The two pushbutton portions can translate one relative to the other and are connected together by tubular appendices which are inserted into and sealedly translatable one within the cavity of the other and are connected to said stem seat and to said nozzle respectively.

Abstract: An operating pushbutton for dispensing pumps for fluid substances contained in containers on which the pumps are mounted. The pushbutton has an end portion which can translate on a portion thereof applicable to the pump stem, such that when a pressure is exerted on said end portion it undergoes a free translation before causing the other pushbutton portion to move, hence preventing accidental dispensing of the fluid substance.

Abstract: A metering pump including a main body having a first surface, a member for attachment to a bottle, an inlet valve, an elastomeric head having a second surface, where both surfaces define a pumping chamber, and a discharge valve having a valve seat and a moving member adapted to move between a first closed position and a second open position. The moving member extends from the head forming a partition and is integral with the head. The first and second surfaces are relatively movable therebetween causing pumping of a liquid. When the moving member is in the first position and there is a reduced pressure in the pumping chamber, the reduced pressure then presses the moving member against the valve seat.
