摘要:
A nozzle cap of a trigger actuated pump sprayer is produced of two different materials using a bi-injection molding process for delimiting the markings on the outer faces of four walls of the cap serving as indicia relating to specific rotative positions of the cap.
摘要:
A sprayer includes a discharge valve assembly and includes an integrated poppet valve, spring and volume reducer. The spring includes more than omega-shaped form, each with relatively flat sides. The spring can have sides with portions sufficiently wide to substantially extend across the valve chamber to provide stability to the spring and prevent buckling. The flat sided omega-form construct is relatively easy to manufacture via molding and the ends of such construction provide suitable locations for integrated molding with the valve and the volume reducer.

An assembly for effecting a quick connect of a flexible fluid delivery tube to a rigid dip tube for a liquid sprayer is provided. The assembly is mounted to a container of chemical liquid to be sprayed by a closure cap having a depending annular wall defining a cavity into which an adaptor for the delivery tube extends and is snap fitted in place by the provision of a retention feature coacting between a nipple of the adaptor and the annular wall. A vent port located in the annular wall in the vicinity of the coacting retention feature with an air gap provided between the vent port and the upper surface of the closure end wall. Alternatively, the vent port is located in the end wall of the closure. A cover is provided for sealing closed both the inlet opening from the container and the vent port in a condition of non-use.
摘要:
A manually actuated dispenser having a flexible weighted dip tube is mounted to a container of liquid to be dispensed without entanglement by the dip tube by the provision of a tubular extension on the tube retainer which surrounds the tube and has a releasable holder for maintaining the tube in a collapsed condition during installation within the container, the retainer being dislodged or being soluble in the liquid in the container for releasing the stored dip tube permitting the ballast weight at its end to extend the tube toward the container bottom wall assuring a wetted condition of the inlet end of the tube during all attitudes of liquid dispensing.
