Abstract
The present application is directed to cap assemblies and particularly, cap assembly for closing an opening in a vessel, the cap assembly including a stopper including an polymer body adapted to fit an opening of a vessel, the stopper also including a tubular portion which defines an internal passageway extending through the polymer body; and a rigid cap attached to and integral with the stopper, wherein the cap is adapted to engage the vessel and provide a sealing force between the stopper and the vessel.
Claims20
A cap assembly for closing an opening in a vessel, the cap assembly comprising:
- a stopper including a polymer body comprising a substantially cylindrical section, the stopper also including more tan one non-concentric tubular portions which defines an internal passageway extending through the polymer body, wherein at least one of the tubular portions and the polymer body are a single molded component, wherein at least one of the tubular portions extends axially away from a top surface and a bottom surface of the polymer body;
- and
- a rigid cap attached to or integral with the stopper, wherein the cap is adapted to engage the vessel and provide a sealing force between the stopper and the vessel, wherein the rigid cap comprises a radial flange defining a central bore, wherein the substantially cylindrical section of the stopper comprises a top surface located above an uppermost top surface of the cap in the axial direction down a central axis, and wherein the substantially cylindrical section of the stopper substantially fills the central bore.
