  • Patent number: 6279784
    Abstract: A trigger activated pump sprayer to be attached to a fluid filled container so that fluid from the container can be delivered to and sprayed from a nozzle. A one piece combination dual action spring and fluid chamber is housed within a shroud. The combination is manufactured from a resilient rubber material having a spring-like memory and including an expandible spring section integrally connected to and axially aligned with a collapsible fluid chamber section. A trigger that is adapted to rotated within the shroud is coupled to the combination between the expandible spring and collapsible fluid chamber sections thereof. When the trigger is manipulated (i.e. rotated) by a user during a dispensing cycle, the expandable spring section is stretched and the collapsible fluid chamber section is compressed to increase the pressure within the fluid chamber section whereby to break a seal and open a fluid path between the fluid chamber section and the nozzle.

  • Patent number: 5562250
    Abstract: A trigger sprayer apparatus for use with a container having multiple compartments, the apparatus having a pump for drawing liquid from the container compartments to the pump, wherein check valves prevent liquid from backflowing from the pump to the compartments and the pump has control valves for selecting the mixture ratio of the liquids entering the pump.

  • Patent number: 5358149
    Abstract: A pressure build-up pump sprayer to be interconnected with a liquid filled container and having a poppet assembly including inner and outer coaxially aligned pressure chambers. The inner pressure chamber communicates with the orifice outlet of the sprayer, and the outer pressure chamber is initially filled with air. Prior to priming the sprayer, an air-tight seal isolates the inner and outer pressure chambers from one another. During the priming cycle, the air-tight seal is broken and air trapped within the outer pressure chamber is exhausted through the orifice outlet by way of the inner pressure chamber. The outer pressure chamber is then filled with liquid that is sprayed therefrom through the orifice outlet during a downstroke of the liquid dispensing cycle.

  • Patent number: 5088629
    Abstract: A manually actuated, pressure build-up pump sprayer that is to be interconnected with a container for atomizing and spraying a liquid from the container. The pump sprayer includes air-tight seals and valves which are opened and closed at different portions of the stroke cycle, such that trapped air may be quickly compressed and efficiently blown from the poppet into the container and liquid from the container drawn into the poppet and sprayed from the spray head. Thus, the sprayer may be easily primed after only a few stroke cycles. The sprayer is characterized by a relatively reduced number of parts and manufacturing cost as well as the ability to prevent leakage and allow spraying of the liquid in the event that the container is tipped or turned over.

  • Patent number: 4990014
    Abstract: A closure assembly to be removably attached across the open neck of a container that contains a supply of fluid. The closure assembly includes an elongated stem which extends into the container and an applicator brush which is attached to the stem so that the fluid within the container may be easily accessed. The closure assembly also includes a cap portion which can be manually rotated so as to impart a corresponding rotation to and axial (i.e. linear) displacement of the stem, whereby to cause the applicator brush to be easily and efficiently lowered into the container in the event of a short fluid supply.

  • Patent number: 4923094
    Abstract: A relatively low cost, manually actuated pressure build-up pump sprayer to be interfaced with a liquid container for atomizing and spraying any one of a variety of different liquids which may be stored within the container. The pump sprayer is characterized by a fewer number of components and a higher speed of assembly than that by which most conventional sprayers are characterized. The pump sprayer is also characterized by a single, axially and continuously extending pressure chamber and a continuously extending pair of bores having different diameters relative to one another. Moreover, the sprayer includes a number of seals which may be selectively opened and closed at particular times during the stroke cycle so as to provide the reliable venting and efficient priming in response to a lower actuating force.

  • Patent number: 4420101
    Abstract: A self-venting dispensing closure for fluid-tight engagement with a squeeze bottle includes a cap containing a fluid opening, a flexible disc on the cap containing a fluid bore which defines together with such opening a single fluid passageway through the closure, the cap including an annular wall defining a valve seat lying upstream of the fluid opening in the direction of product flow through the passageway, the disc having an annular valve thereon in engagement with the valve seat in a closed position of the passageway, and the valve being shiftable along the annular wall to positions respectively upstream and downstream of the valve seat in response to sub-atmospheric and super-atmospheric pressures within the bottle. In these shifted positions, the valve opens respectively into bottle venting and dispensing positions. An overcap in engagement with the cap may be provided for closing the fluid passageway in a non-use and/or storage condition of the bottle.

  • Patent number: 4371097
    Abstract: A liquid dispensing pump includes a one-piece piston capable of not only effecting a pumping operation but also an outlet valve opening and closing function upon limited relative axial movement. In one embodiment, the piston reciprocates and forms a valve seat for a container vent opening extending through a closure cap provided on the pump body, and in another embodiment, the pump cylinder reciprocates and forms a valve seat for opening and closing the container vent opening. The pump chamber defined by the cylinder has a valved inlet which may be formed by a sleeve depending from the piston and an upstanding conduit in the cylinder or may be formed by a ball check valve in the cylinder.

  • Patent number: 4189064
    Abstract: A dispensing pump of the pressure build-up variety includes a cylinder defining a variable volume pump chamber, and a main piston reciprocable therein, the piston having a valve seat thereon communicating with a discharge passage leading to a discharge nozzle. A valve member having a smaller diameter piston thereon is moved during pressure build-up away from the seat for opening the discharge passage. The smaller diameter piston has a flexible peripheral wall which is deformed inwardly at the commencement of the piston downstroke for closing a flow passage in the smaller diameter piston and thereby interrupting communication between the inlet and the pump chamber, such flow passage being open upon outward movement of such peripheral wall at the end of the piston upstroke. At the top of the cylinder along which the smaller diameter piston moves is a relieved section effecting the opening of the flow passage in an inoperative condition of the pump.
