    摘要: A sprayer device with a trigger operated pump is operative for pumping and spraying liquid from an attached liquid container. The trigger sprayer includes valve body provided with a base portion that is configured to be mounted to the neck of the liquid container and a delivery nozzle from which the liquid is sprayed. A fluid flow path extends from the base portion to the delivery nozzle. A pumping chamber is in fluid communication with the flow passage and there is a vent opening between the pumping chamber and the interior of said base. A piston with spaced inboard and outboard seals is movable in the pumping chamber and the vent opening is located between the seals. A check valve is disposed between the vent opening and the interior of the base portion to prevent liquid from the container from backflowing into the pumping chamber during shipment and handling.

    摘要: A dispensing system includes a liquid dispensing tap, an associated measuring cap/cup and a cap adapter or holder which is removably received onto the tap and which in turn removably receives the cap/cup. The dispensing tap, adapter/holder and cap/cup are configured such that the holder and cap/cup are assembled with the tap prior to installation onto a container, and stay assembled with the tap during installation onto the container at the filling line, and which can later be removed for use and then selectively reattached to the tap or container after use by the consumer.

    摘要: A pump dispenser includes an actuator having at least one outward projection and a rotatable actuating collar at least partially surrounding the actuator and having at least one ramp rib defining a lower surface which engages the at least one outward projection such that rotation of the rotatable actuating collar acts on the actuator to dispense a product from or through the pump dispenser.
