| 20090152304 | Break-Away Spring and Piston Rod for a Trigger Sprayer - A manually operated trigger sprayer has an integral plastic spring and pump piston rod that are connected by a breakable connection, whereby the spring and piston rod can be assembled to the trigger sprayer as one piece and are subsequently broken into two separate pieces in response to their assembly to the trigger sprayer, or subsequent manual operation of the trigger sprayer. | 06-18-2009 |
| 20090179047 | Dual chamber lotion pump - A manually operated vertically reciprocated pump dispenser has a simplified construction with two separate pumps that pump two separate liquids from a container and keep the two separate liquids separated from each other as they are pumped through the dispenser, mixing the liquids for the first time in a discharge passage of the dispenser just prior to the mixed liquids being discharged from the dispenser. The dispenser has a rotatable sleeve that covers the two pumps and is rotated to lock and unlock a dispenser head that operates the two pumps. | 07-16-2009 |
| 20090256008 | Trigger Sprayer Nozzle Assembly with Pull/Push Foaming Tube - An indexing nozzle assembly for a trigger sprayer is comprised of a nozzle base that is attachable to a sprayer housing of the trigger sprayer, a cap that is mounted for rotation on the nozzle base, and a foaming tube that is mounted for linear reciprocating movement on the cap. Rotation of the cap on the nozzle base changes liquid discharge from the trigger sprayer between an off condition and at least a spray condition. In the spray condition of the nozzle cap, the foaming tube can be manually pulled and extended from the nozzle cap. With the foaming tube extended from the nozzle cap, the liquid discharge from the nozzle assembly in a spray pattern comes into contact with an interior surface of the tube and generates a foam discharge from the nozzle assembly. | 10-15-2009 |
| 20090308897 | Trigger Sprayer Having a Reduced Number of Parts and a Double Tubular Valve Member - A trigger sprayer has a one piece valve member that includes both an inlet valve element and an outlet valve element. The one piece valve member replaces the separate liquid inlet valve and liquid outlet valve of a conventional trigger sprayer, and thereby provides a more simplified construction for the trigger sprayer and a fewer number of component parts in the trigger sprayer. | 12-17-2009 |
| 20110240681 | Low Cost Trigger Sprayer - A trigger sprayer has a housing, a piston bore within the housing, and a piston reciprocally mounted within the piston bore. The housing further includes a flow passage through which liquid passes from a passage inlet to a passage outlet. An actuator is operable to reciprocate the piston within the piston bore between a vacuum stroke creating reduced pressure in the piston bore and a compression stroke creating increased pressure in the piston bore. A valve assembly within the flow passage controls the flow of liquid through the flow passage upon operation of the actuator. The valve assembly further comprises a check valve and a priming valve. The sprayer has a closure for mounting the sprayer to a container. The valve seat for the check valve is in a component formed separately from and operatively connected to the housing. | 10-06-2011 |

| 20080308072 | HYDROCARBON SEPARATION FROM AIR USING MEMBRANE SEPARATORS IN RECIRCULATION TUBE - A tubular separation system for separating a mixture of hydrocarbons and air at a fuel tank in an automotive vehicle, comprises; a fuel tank containing hydrocarbon fuel and a mixture of hydrocarbon fuel vapor and air; a fuel filler pipe connected to the fuel tank for conveying hydrocarbon fuel from a source of hydrocarbon fuel into the fuel tank; a separation module comprising a membrane for separating the hydrocarbon vapor from air; a first tubular member between the fuel tank and the separation module for conveying the mixture of air and hydrocarbon fuel vapor from the fuel tank to the separation module; a second tubular member between the separation module and the fuel tank for conveying hydrocarbon fuel vapor, separated from the mixture of air and hydrocarbon fuel vapor, from the separation module to the fuel tank; and a third tubular member between the separation module and the fuel filler pipe for conveying air, separated from the mixture of air and hydrocarbon fuel vapor, from the separation module to the fuel filler pipe. A device that provides a pressure differential across said membrane is employed to facilitate the separation of air and hydrocarbon from the air/hydrocarbon mixture. The air containing any residual fuel vapor is directed to an emissions canister where the residual fuel vapor is adsorbed and eventually consumed by the internal combustion engine while the air is released to the atmosphere. | 12-18-2008 |
| 20080308073 | EVAPORATIVE EMISSIONS CANISTER HAVING AN INTEGRAL MEMBRANE - An evaporative emissions canister for use in an automotive evaporative emission system to control emission of fuel vapors to the atmosphere. The canister includes an integrally molded housing having a circumferential side member, a top member and a bottom member; a hydrocarbon-adsorbing material disposed therein so as to provide a vapor adsorbent chamber for adsorbing hydrocarbon fuel vapor flowing therethrough; and an internal membrane located above the vapor adsorbent chamber in the fresh air side of the adsorbent chamber for preventing the fuel vapor molecules from passing through the internal membrane while allowing the air molecules to pass therethrough. The internal membrane is characterized as a cellular fibular material having physical properties sufficient to effectively cause any fuel vapor component molecules and associated pollutants to be sufficiently filtered or separated on the membrane while allowing fresh air molecules to pass freely therethrough. | 12-18-2008 |
| 20080308074 | EVAPORATIVE EMISSIONS CANISTER WITH EXTERNAL MEMBRANE - An evaporative emissions system is used in an automotive evaporative emission system including a fuel tank coupled to an automotive engine to control emission of fuel vapors to the atmosphere. The system includes (1) an evaporative emissions canister comprising a unitary molded housing having a circumferential side member, a top member and a bottom member; a hydrocarbon-adsorbing material disposed therein so as to provide a vapor adsorbent chamber for adsorbing hydrocarbon fuel vapor flowing therethrough; and (2) a second housing containing a membrane, the second housing located adjacent the fresh air line of the evaporative emissions canister for preventing fuel vapor molecules and pollutants associated therewith, from passing through the membrane while allowing the air molecules to pass therethrough. A method is provided for preventing or substantially reducing hydrocarbon emissions to the atmosphere. | 12-18-2008 |
