Abstract
Abstract A method of fabricating a fluid collection bottle or container having as a fundamental concept a provision of integral port extensions molded in the principal port of the over-all container construction. Positive and negative, intercooperating molds are provided, and this with pin means and corresponding alignment aperature means whereby, with the slideable cooperation of such pin means and the alignment aperture means, the positive and negative molds may be strictly maintained on centerline, thereby insuring uniform wall thickness of the container produced. Subsequent to the formation of the container, a closure member is provided at that end of the container remote from the so-formed ports.
