UNIVERSAL THREAD FLUID CONTAINER ENCLOSURE SYSTEMS

The present invention discloses an enclosure system for enclosing a plurality of types of fluid containers, comprising a cap component comprising a skirt having a plurality of internal threads arranged on an internal surface thereof to engage port threads of a port of the plurality of types of fluid containers; and a biasing component coupled to a portion of the skirt to bias the skirt inward; wherein the skirt is configured to expand outward against biasing of the biasing component responsive to internal pressure of the port on the internal surface as the cap component is pushed down on the port to increase an inner diameter of the skirt to allow the plurality of internal threads to engage port threads having different dimensions.
