A pump system may include a blown-in dip tube connected to a valve body and having a connection which may include an improved blown-in dip tube connector having one or more of a lip for sealing with a blown-in dip tube, a seal ring configured to mate with a blown-in dip tube and seal therewith, a dip tube lock for mating with a blown-in dip tube, or an o-ring for providing an improved seal with a blown-in dip tube.

Locking features of a pump system may include projections and corresponding features on a piston stem and lock cylinder of a pump system such that the features are configured to require an increased amount of force to rotate and unlock the piston stem from the lock cylinder.

A dispensing pump () includes a removable chaplet () to facilitate removal of the internal metal spring components () for recycling. The dispensing pump () includes an accumulator () having an upper rim wall (). The chaplet () is coaxially snap received about the rim wall () of the accumulator (). The chaplet () has a body portion () received within the rim wall (), and an outer wall () received outside of the rim wall (). The outer wall () has a frangible wall portion () and a pull tab () at a terminal edge thereof. A dispensing head () with a piston stem () and spring () are coaxially guided within the chaplet () and accumulator (). When the container is empty, the user pulls on the pull tab () to sever the frangible elements, releasing the chaplet () and allowing easy removal of the dispensing head () and the metallic spring component ().

A pump dispenser head has a lockdown feature to prevent unintended dispensing during shipment. Releasing the lock-down feature requires increased torque compared with typical dispensers, allowing the dispenser to be shipped with less packaging while still preventing leakage of the contents.

A pump system may include a blown-in clip tube connected to a valve body and having a connection which may include an improved blown-in clip tube connector having one or more of a lip for sealing with a blown-in clip tube, a seal ring configured to mate with a blown-in clip tube and seal therewith, a clip tube lock for mating with a blown-in clip tube, or an o-ring for providing an improved seal with a blown-in clip tube.

A pump dispenser includes a dispenser head rotatable relative to a locking ring for a lock-down feature during shipment. The lock-down feature requires a greater torque to initially rotate the dispenser head from the lock-down position, and a lesser torque to further rotate the dispenser head to a use position. The lock-down feature incorporates an interference between the dispenser head and locking ring, either inside the dispenser head, on an outer periphery of the dispenser head, or between threads connecting the dispenser head and locking ring.

A sprayer device with a trigger operated pump is operative for pumping and spraying liquid from an attached liquid container. The sprayer device includes an integrally molded 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 pumping chamber in the valve body is in fluid communication with an inside of the fluid container and is further in fluid communication with the delivery nozzle. The valve body is further provided with a head portion that has a filling passage extending between the head portion and the base portion such that a liquid received in the head portion flows through the valve body, around the pumping chamber and exits the base portion into the mounted liquid container.

A pump engine assembly includes an output cylinder that may be customized to include a stop portion limiting the stroke of a piston to produce a particular output such that customized pump systems may be produced from similar parts with the exchange of only a single part&#x2014;the output cylinder.

Fluid dispenser

A pump system may include a blown-in dip tube connected to a valve body and having a connection which may include an improved blown-in dip tube connector having a swivel adaptor, or a rotatable connector, which creates a fluid path from a blown-in dip tube of a bottle to a trigger sprayer. The swivel adaptor, or rotatable connector, may also include a body or head which may be attached to a valve body, tube retainer, or valve retainer of a trigger sprayer.
