Publication number: 20230175571Abstract: A dispensing pump (1000) includes a polymer compression spring (1048), base vents (1060) and a flow baffle (1092). The dispensing pump includes a pump base (1002), and a dispensing head (1004) having a piston stem (1034). The polymer compression spring assembly includes a slotted tubular spring element (1048) 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.Type: ApplicationFiled: April 24, 2021Publication date: June 8, 2023Applicant: Silgan Dispensing Systems CorporationInventors: Eelco H. Deman, Stefan Koster

Patent number: 10794445Abstract: 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.Type: GrantFiled: August 19, 2019Date of Patent: October 6, 2020Assignee: Silgan Dispensing Systems CorporationInventors: Eelco H. Deman, Stefan Koster

Patent number: 10365140Abstract: A dispensing closure for dispensing flowable product from a squeeze container includes a closure body having an upper deck and a dispensing orifice within the upper deck. A timing piston extends downwardly from the upper deck and is located adjacent to the dispensing orifice. The timing piston is movable between an open position wherein a flared piston neck is spaced from the dispensing orifice, and a closed position wherein the flared piston neck closes off the dispensing orifice. A timing vent within the upper deck is in communication with a piston chamber to allow air to escape the piston chamber. An air intake orifice within the upper deck allows air to enter the piston chamber, and a ball valve structure adjacent the bottom surface of the upper deck cooperates with the air intake orifice to control the flow of air through the air intake orifice.Type: GrantFiled: May 27, 2016Date of Patent: July 30, 2019Assignee: Silgan Dispensing Systems Netherlands B.V.Inventors: Stefan Koster, Eelco DeMan
