APPARATUS AND METHOD FOR DISPENSING A FLUID

Номер: US20200008558A1
Автор: Forrest Brad, Megaro Arianna, Megaro Matthew
Принадлежит:

A fluid transfer assembly comprises a housing for accommodating a fluid. A bellows member disposed in the housing defines an opening therethrough adapted to be in fluid communication with an applicator assembly. The bellows member is adapted to operatively engage the applicator assembly for extension in a first direction and contraction in a second direction. The bellows member seals against the inner surface of the housing during extension and contraction for defining a variable volume chamber with the housing. Expansion of the bellows member in the first direction reduces the chamber volume for generating positive pressure in the housing and forcing fluid through a valve to the applicator assembly. Contraction of the bellows member in the second direction increases the chamber volume for generating negative pressure within the housing for drawing fluid into the chamber. 2. The fluid dispensing apparatus as recited in claim 1 , further comprising a valve disposed in a fluid flow path from the liner to the pump chamber claim 1 , wherein the valve opens only when the actuator moves in the second direction for allowing fluid flow from the liner to the pump chamber.3. The fluid dispensing apparatus as recited in claim 1 , wherein the valve at the outlet end of the opening through the bellows member opens only when the actuator moves in the first direction.4. The fluid dispensing apparatus as recited in claim 3 , wherein the valve comprises a duckbill valve for permitting fluid flow through the valve only in response to pressurizing of fluid upstream of the valve such as by moving the actuator in the first direction.5. The fluid dispensing apparatus as recited in claim 1 , wherein the at least one opening comprises a plurality of fluid receiving ports in a generally radial array claim 1 , the ports opening into the pump chamber.6. The fluid dispensing apparatus as recited in claim 5 , wherein the fluid receiving ports are positioned symmetrically about a central axial ...

PUMP MECHANISM FOR A SPRAY DISPENSER

Номер: US20180200744A1
Автор: AWORTH Christopher John
Принадлежит:

A pump mechanism for a spray dispenser, comprising a piston assembly movable with respect to a housing between charged and initial positions. The piston assembly comprises liquid and gas seals, being movable boundaries of respective chambers whose volume is determined by the position of the seal relative to the housing. When the piston assembly moves toward the charged position, the volume of the liquid chamber increases to draw liquid into the liquid chamber and the changing volume of the gas chamber changes the pressure of gas in that chamber from its pressure when the piston assembly was in the initial position. This biases the piston assembly to return from the charged position toward the initial position, that return movement of the piston assembly pressurising the liquid in the liquid chamber for dispensing. 2. The pump mechanism of claim 1 , wherein:when the piston assembly moves from the initial position to the charged position, the volume of the sealed gas chamber is decreased and the internal pressure of the gas is increased; orwhen the piston assembly moves from the charged position to the initial position, the volume of the sealed gas chamber is increased and the internal pressure of the gas is decreased.3. The pump mechanism of claim 1 , wherein:when the piston assembly moves from the initial position to the charged position, the volume of the sealed gas chamber is increased and the internal pressure of the gas is decreased; orwhen the piston assembly moves from the charged position to the initial position, the volume of the sealed gas chamber is decreased and the internal pressure of the gas is increased.4. The pump mechanism of claim 1 , wherein the housing comprises a tubular body closed by a base wall.5. The pump mechanism of claim 4 , wherein the base wall comprises the inlet to the liquid chamber.6. The pump mechanism of claim 1 , wherein a non-return valve is provided in a duct leading to the inlet.7. The pump mechanism of claim 1 , wherein the ...

The present invention relates to a press-type liquid pump. The liquid pump comprises a fixed unit fixed relative to a container and a movable unit capable of performing a reciprocating motion relative to the fixed unit, and a liquid product is pumped to the exterior of the container. The reciprocating motion is achieved by a pressing force applied by a user to the movable unit to move the movable unit relative to the fixed unit in combination with an elastic restoring means for restoring the movable unit relative to the fixed unit after the pressing force is removed. The elastic restoring means is a plastic elastic compressing means located below a toothed sleeve and installed between the fixed unit and the movable unit, which comprises at least one elastic strip generally formed in an arc shape.
