A gaged dispensing apparatus, comprising: a container for holding a supply of a viscous material, said container having an opening at one end thereof for permitting the discharge of said viscous material from said container; and resilient metering means, interposed between a first chamber of said container which holds a supply of viscous material and a second chamber of said container which communicates with said opening, for limiting the volume of said material dispensed through said opening to a predetermined volume in response to the application of pressure to said first chamber of said container, said resilient metering means including a plastic reciprocating element which has a body following a generally spherical arc that is normally bowed away from said opening of said container, and aperture means formed at least in part by said reciprocating element for permitting said viscous material to flow from said first chamber to said second chamber until said generally spherically arcing body provides a metering seal between said first and second chambers in a closed position, said seal preventing discharge of additional viscous material from said opening.
