    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: 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).

    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 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 peripheral 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 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 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.
