Abstract: A dispensing pump includes a polymer compression spring assembly, base vents and a flow baffle. 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 venting ports allow air to escape when capping the container after filling and the flow baffle reduces or prevents the product from being pulled into the pump accumulator before residual air (headspace) has been evacuated from the container during the initial priming strokes.

Abstract: 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.

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 timing device is integrated into a pour cap to visually indicate when a dose has been dispensed from the container. The timing device may be secured to either the pour cap or the container and timing is configurable based on a product being dispensed.

Abstract: 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.

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.

Abstract: An all plastic compression spring assembly includes a slotted tubular spring element formed from a tensile polymer material and upper and lower loading cones received at opposing upper and lower ends of the slotted tubular spring element. The upper loading cone may be axially compressible towards the lower loading cone within the slotted tubular spring element whereby the slotted tubular spring element radially expands in tension to create an opposing radial contraction force, and in turn, an axial extension spring force. When released, the spring element elastically returns to its normal at rest shape, returning the cones to their normal at rest positions. In some dispenser configurations, the lower loading cone may be stationary or fixed within the dispensing head and the upper loading cone may be downwardly compressible toward the lower loading cone by movement of a nozzle head.

Abstract: A two-piece measured-dose dispensing closure (10) includes a cup-shaped measuring chamber (12) and a rotatable dispensing control lid (14). In use, the dispensing control lid is axially moved relative to the measuring chamber by rotation between a first closed position, a second intermediate dispensing position, and a third drain position.

Abstract: An aerosol actuation system may include an aerosol actuator formed of a first molded component including a housing, a manifold connected to the housing and a button in communication with the manifold, and a molded cap. The aerosol actuator may be assembled with an aerosol container.

Abstract: A dispensing system includes a pour cap for a container and a timing device configured to visually indicate when a dose has been dispensed from the dispensing system, the timing device being securable to either the pour cap or the container and configurable based on a product being dispensed.

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 sustained duration trigger sprayer capable of dispensing at least 3 mL of product over a time period of about 3 seconds utilizing a force-to-actuate of between about 10 pounds and about 15 pounds. The trigger sprayer includes an enlarged piston bore and piston and an elongated trigger lever creating a high output fluid displacement with a 0.5 inch displacement distance. The container bottle and/or the sprayer shroud are contoured to provide a gripping area opposing the terminal end of the trigger lever wherein the gripping distance in from the gripping area to the terminal end of the trigger lever is no greater than 3.3 inches.

Abstract: A dispensing system (2000), includes a container (900) containing a flowable base formulation (910) to be dispensed, an additive mixing device (2004), and an actuable pump engine (2002) which draws the flowable base formulation from the container and pumps it through the mixing device. The additive mixing device includes a body (2022) with an internal cavity (2052), an additive ingredient (2054) within the cavity, and a flow path/mixing chamber (2058) between an input and an output. With each pump of the device (2004) the additive ingredient is introduced into, and mixed with, a flow of the base formulation traveling through the mixing device. Multiple additive mixing devices (2004) may be interchangeable for different formulations, and the mixing devices may be refillable.

Abstract: Embodiments of the invention related to dispensing devices (100), and more particularly to dispensing devices having a dropper or dispenser (200) associated with a container (900) full of product wherein the dropper (200) may be charged, separated from the container (900), and then used to dispense a product therefrom.

Abstract: A dispensing pump (10) includes a removable chaplet (28) to facilitate removal of the internal metal spring components (44) for recycling. The dispensing pump (10) includes an accumulator (12) having an upper rim wall (24). The chaplet (28) is coaxially snap received about the rim wall (24) of the accumulator (12). The chaplet (28) has a body portion (30) received within the rim wall (24), and an outer wall (32) received outside of the rim wall (24). The outer wall (32) has a frangible wall portion (48) and a pull tab (50) at a terminal edge thereof. A dispensing head (36) with a piston stem (38) and spring (44) are coaxially guided within the chaplet (28) and accumulator (12). When the container is empty, the user pulls on the pull tab (50) to sever the frangible elements, releasing the chaplet (28) and allowing easy removal of the dispensing head (36) and the metallic spring component (44).
