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.

Dip tube connectors and pump systems using the same

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 dispensing pump for liquids, viscous materials, foams, gels, etc. includes a resilient plastic skirt spring so that the entire pump can be more easily recycled. The skirt spring comprises a plurality of concentric nesting rings sequentially decreasing in diameter from a base ring to a top ring to form a conical shape wherein adjacent rings are interconnected by spaced bridge segments and the bridge segments are staggered at each sequential ring.

Embodiments of the invention relate to dosing dispensers and in particular to dosing dispensers that may be operated using one hand by raising and filling a dosing chamber followed by lowering and dispersing a product from the dosing chamber and wherein the dose may be selected or adjusted and a user may visually confirm that the proper dose is being loaded and delivered by the dispenser.

Adjustable dosing dispensers and methods for using the same

A sustained duration trigger sprayer includes a first vacuum formed by piston movement in a fluid cylinder which fills the sprayer for delivery of a fluid and a second vacuum formed between a vacuum piston connected to the fluid cylinder and a vacuum cylinder acts on the sprayer to disperse product when a discharge valve is opened.

A dispensing pump () for liquids, viscous materials, foams, gels, etc. includes a resilient plastic skirt spring () so that the entire pump can be more easily recycled. The dispensing pump () includes a base portion (), an inlet valve (), a piston valve (), a polymer skirt spring (), a spring guide structure () and a pump actuator (). The skirt spring () comprises a plurality of concentric nesting rings () sequentially decreasing in diameter from a base ring (A) to a top ring (F) wherein adjacent rings are interconnected by spaced bridge segments () and the bridge segments are staggered at each sequential ring. The skirt spring () includes structures which interact with the piston valve () to open the outlet valve.

A trigger sprayer having a valve body configured to accept a discharge valve for a pre-compression configuration or a valve and plug combination for a non-pre-compression configuration where the discharge valve may include a frame and valve which may be bi-injected or assembled to provide a pre-compression valve for the trigger sprayer.
