  • Patent number: 7455198
    Abstract: A manually operated trigger sprayer includes a feature that limits the forward pivoting movement of the trigger. By limiting the forward pivoting movement of the trigger, the novel construction of the trigger sprayer prevents the trigger from engaging against the nozzle assembly attached to the sprayer housing of the trigger sprayer and potentially dislodging the nozzle assembly from its attachment to the trigger sprayer housing.

  • Publication number: 20080110941
    Abstract: A cap closure that dispenses liquid from a liquid container has a cylindrical base that is removably mounted on the liquid container. A valve spout is mounted on the base for linear reciprocating movement. A valve actuator is mounted on the base for rotation. The spout is movable between closed and opened positions where in the opened position liquid can be dispensed through the spout and in the closed position the liquid is blocked from passing through the spout. The actuator is operatively connected to the spout whereby rotation of the actuator between first and second positions relative to the cap base moves the spout between the respective closed and opened positions of the spout on the base.

  • Publication number: 20070228187
    Abstract: An indexing nozzle assembly for a trigger sprayer has a manually rotatable cap mounted for rotation on a base of the nozzle assembly. Rotation of the cap relative to the base changes the nozzle assembly between an off condition where the nozzle assembly prevents liquid discharge from the trigger sprayer, and a combination of a spray condition, a stream condition, and/or a foam condition. The indexing nozzle assembly is provided with a child resistant feature in the form of a lock mechanism that prevents rotation of the nozzle cap relative to the nozzle base from the cap off condition position. The lock mechanism can be manually manipulated with one hand to disengage the lock mechanism, thereby permitting rotation of the nozzle cap from its off condition position relative to the base.

  • Patent number: 7195138
    Abstract: A closure is removably attachable to a container and comprises a dispensing orifice and a valve element that is biased closed over the orifice. By inverting the container so that a liquid contents of the container exerts pressure on the valve element, or by squeezing the container causing the liquid contents to exert pressure on the valve element, the valve element opens the dispensing orifice allowing the liquid contents to be dispensed from the container. On removing the pressure from the valve element, the valve element resiliently closes the dispensing orifice.

  • Publication number: 20040118873
    Abstract: A telescoping closure is removably attached to a flexible container that can be manually squeezed to dispense contents of the container through the closure when the closure is moved to an opened position. The closure comprises a cap and a dispensing tip that are both mounted for rotation on a container connector that attaches the closure to the container. On rotation of the cap relative to the container connector the dispensing tip rotates with the cap and moves axially relative to the cap to project the dispensing tip axially outwardly from the cap and open an orifice in a distal end of the dispensing tip. With the orifice opened the contents of the container can be dispensed by inverting the container and cap and manually squeezing the container. The cap is rotated in an opposite direction to cause the dispensing tip to move axially back into the cap closing the orifice at the distal end.
