Patent number: 11858799Abstract: A dispensing tap (700) for liquids includes a body (702) connected to the neck of a container (900), a dispensing head (708) with an outlet or mouth (714), and a throat (710) connecting the body to the dispensing head. A shut off valve (716) is configured for sealing engagement with the mouth of the dispensing head, and a piston (718) is axially guided within the dispensing head. The piston includes a peripheral seal (720) slidably engaged with an interior surface of the dispensing head, and a valve stem (722) coupled to the shut off valve. The piston is selectively actuable between a normally closed position an open position. A vent (740) 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.Type: GrantFiled: December 5, 2020Date of Patent: January 2, 2024Assignee: Silgan Dispensing Systems CorporationInventors: Willam Driskell, Brandon Ramsuer, Eelco H.

Patent number: 11754137Abstract: 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.Type: GrantFiled: July 12, 2021Date of Patent: September 12, 2023Assignee: Silgan Dispensing Systems CorporationInventors: Eelco H. Deman, Paulus Zuijderduijn

Patent number: 10495173Abstract: 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: October 18, 2018Date of Patent: December 3, 2019Assignee: Silgan Dispensing Systems CorporationInventors: Eelco H.
