  • Publication number: 20240033755
    Abstract: Disclosed is a pump assembly having slidingly engaged upper and lower sleeves, and a pump having an inlet and outlet ends and a pump chamber therebetween. Movement of the lower sleeve towards the upper sleeve causes the pump chamber to reduce in volume. The outlet end of the pump has a shoulder between a first diameter portion and an outlet nozzle extending downwardly from the shoulder and having a second diameter smaller than the first diameter portion. The lower end of the lower sleeve includes a shield extending from a lowermost rim upwards and inwards to terminate at an orifice that is larger than the second diameter but smaller than the first diameter portion. The shoulder supporting against a lip of the orifice and the outlet nozzle extending through the orifice to terminate at a dispersion location within the shield at a distance L from the orifice.

  • Patent number: 8708200
    Abstract: A disposable pump for liquid dispensing includes a chamber in which pressure may be varied for pumping liquid from a compressible container to the chamber to a dispensing opening. The chamber encloses an inner valve that regulates liquid flow between the container and the chamber, and an outer valve regulates flow of liquid between the chamber and the dispensing opening. The pump has a closed position where liquid is drawn from the container to the chamber by negative pressure in the chamber. To dispense, a volume of liquid is drawn from the chamber to the dispensing opening. The inner valve is a one-way valve openable to flow liquid in the dispensing direction when inner valve opening pressure acts in the dispensing direction, and closes for pressure acting in the opposite direction. The outer two-way valve opens to flow liquid in the dispensing or opposite direction.
