The protruding port defines a spike insertion chamber extending from a spike connector insert aperture to a spike connector outlet aperture. The outer ring is configured for attachment to a container having a mouth. The insert cutter has a first end portion attached to the bottom surface of the base and about an edge of the spike connector outlet aperture and a second end portion extending over at least a portion of the spike connector outlet aperture. The insert cutter is capable of flexing in an insertion direction of a spike connector inserted through the spike insertion chamber.
