Abstract
Apparatus for injecting flowable material in which a container holds flowable material. Disposed within the container is a plunger which is formed with metering apertures extending therethrough. The metering apertures store predetermined quantities of material to be mixed with the material in the container. A flexible member is disposed adjacent the plunger between the discharge opening of the container and the plunger. When the plunger travels away from the discharge opening, the flexible member unseals the metering apertures for mixing the material in the plunger with the material in the container. When the plunger travels toward the discharge opening, the flexible member seals the metering apertures in the plunger to discharge the mixed material in the container through the discharge opening.
