ABSTRACT:
This invention concerns apparatus for injecting a special ingredient into a pre-filled product container having superatmospheric internal pressure. Structurally, a coupling member is fabricated to define a cavity that snugly receives a portion of the container body to establish alignment therewith. This coupling member includes a mounting structure for use in positioning a syringe assembly with respect to a pierceable portion of the container body. A syringe assembly includes a syringe body that is mounted on the mounting structure and defines an internal chamber for containing a metered amount of a fluid product ingredient or amendment, the syringe assembly further including a cannulated needle fastened to the syringe body in fluid-transfer relationship with the product ingredient chamber. A wrench member is assemblable with the coupling member and includes an actuator for selectively engaging the syringe assembly and forceably reducing the internal volume of the product ingredient chamber. Force-multiplying mechanical arrangements are arranged to act between the coupling member and the wrench member for urging the actuator to express the contents of the ingredient chamber through the needle and into the product container against its internal pressure.
