Abstract: A dispensing pump includes a polymer compression spring assembly. The dispensing pump includes a pump base, and a dispensing head having a piston stem. The polymer compression spring assembly includes a slotted tubular spring element and first and second loading cones received at opposing ends of the slotted tubular spring element. The first loading cone is fixed relative to the pump base while the second loading cone is axially movable with the piston stem and dispensing head. The tubular spring element is disposed coaxially about the piston stem between the cones. When the dispensing head is compressed, the loading cones axially compress toward each other whereby the slotted tubular spring element radially expands to create an opposing contraction force, and in turn, an axial extension force. When released, the spring element elastically contracts to its at rest shape, returning the loading cones and dispensing head to their at rest positions.
Abstract: 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.
Abstract: 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.
Abstract: A dispensing device is disclosed which provides for dispensing multiple doses from a cylindrical volume. An actuator button moves a tooth to engage a series of links which move a stopper to dispense the doses.
Abstract: An aerosol actuator having a button actuator on a top surface thereof and a lever actuator extending away from the button actuator may be assembled with an aerosol container and valve to provide ergonomic application of a product utilizing the aerosol actuator.
Abstract: 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.
Abstract: The invention relates to a locking feature for an aerosol dispenser head having a locking feature incorporating a locking yoke that requires multiple motions to unlock, and a single motion to reengage the locking feature.
Abstract: 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.

Abstract: A dispensing closure system includes an upper closure portion and a lower closure portion including an axial flow conduit and a vent conduit. The upper closure portion is axially movable relative to lower closure portion between shipping and dispensing positions. A seal is disposed on the lower closure portion over the flow and vent conduits. A peripheral spacing strip is removably secured to the upper closure portion and engages with either the lower closure or the outside of the container to prevent movement. A piercing probe includes piercing elements in alignment with the flow and vent conduits for piercing the seal. In the shipping position, the piercing elements are spaced from the seal. However, when the spacing strip is removed and the upper closure portion is axially moved to the dispensing position, the piercing elements pierce the seal to open the flow conduit and the vent conduit.

Abstract: 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.
Abstract: 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.
Abstract: A dispensing tap for liquids includes a body connected to the neck of a container, a dispensing head with an outlet or mouth, and a throat connecting the body to the dispensing head. A shut off valve is configured for sealing engagement with the mouth of the dispensing head, and a piston is axially guided within the dispensing head. The piston includes a periperhal seal slidably engaged with an interior surface of the dispensing head, and a valve stem coupled to the shut off valve. The piston is selectively actuable between a normally closed position an open position. A spring is captured between the piston and the dispensing head normally biasing the piston and shut off valve to the closed position. A vent is in communication with an interior of the body and the vent is opened and closed with movement of the piston and shut off valve.

Abstract: A dispensing system includes a container containing a flowable base formulation to be dispensed, an additive mixing device, and an actuable pump engine which draws the flowable base formulation from the container and pumps it through the mixing device. The additive mixing device includes a body with an internal cavity, an additive ingredient within the cavity, and a flow path/mixing chamber between an input and an output. With each pump of the device the additive ingredient is introduced into, and mixed with, a flow of the base formulation traveling through the mixing device. Multiple additive mixing devices may be interchangeable for different formulations, and the mixing devices may be refillable.
