Abstract: A refill closure system to be used with bulk refill containers and targeted refill bottles in which the closure system includes a pour cap and a funnel, the funnel being sealed to the pour cap in a closed or non-use state and detached from the pour cap in a use state wherein the funnel may be inserted in a targeted refill bottle to facilitate filling of the targeted refill bottle from a bulk refill container.

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 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.
