Abstract

A cap assembly includes an access member configured for attachment to a reservoir. The access member includes a first port that enables needleless extraction of contents from the reservoir, and at least one second port that enables needled extraction of the contents from the reservoir. The cap assembly further includes a valve member positioned in or configured to be positioned in the access member to i) enable needleless extraction of the contents of the reservoir through the first port when the first port is attached to a needless extraction device, ii) enable needled extraction of the contents through the at least one second port, and iii) seal the contents of the reservoir at the first port and at the at least one second port prior to and subsequent to the needleless or needled extraction.

Core Innovation

The disclosed invention relates to a cap assembly and vial assembly in which a valve member enables needleless extraction of contents through a first port while sealing the contents at the first port prior to and subsequent to the needleless extraction. The access member is configured for attachment to a reservoir and includes the first port, and the valve member is positioned in or configured to be positioned in the access member to enable needleless extraction through the first port when attached to a needleless extraction device and to seal the contents at the first port before and after needleless extraction.

The cap assembly further includes a structural arrangement in which the access member and the valve member are formed from different materials. Both the access member and the valve member include a planar portion, and an outermost diameter of the planar portion of the access member and an outermost diameter of the planar portion of the valve member are substantially the same. In example embodiments, the valve member includes a slit that is sealed when uncompressed and opens upon attachment/compression by an extraction device to allow needleless access while maintaining sealing when not accessed.

In example embodiments, the assembly also provides for needled extraction through one or more second ports. The access member may include planar openings corresponding to second ports and a sealing member that seals the interface between the cap assembly and a reservoir rim. Additional structural features described include a dimple adjacent to the slit, a groove for alignment/needle guiding, and angled sidewalls for needle ports, with variants that include an integrated valve/septum and over-molding of the valve onto the access member, as secured by a hollow bendable metal housing.

Claims Coverage

Independent claim coverage includes three independent claim types covering a cap assembly, a vial assembly, and a package. Across these, the claims share the same core inventive requirements: an access member with a first port enabling needleless extraction and sealing with a valve member, with the access member and valve member formed from different materials and having planar portions with substantially the same outermost diameter, plus housing-based positioning of the planar portions relative to the reservoir rim.

Across independent claims, the invention centers on a cap assembly, vial assembly, and package in which an access member with a first port cooperates with a valve member that enables needleless extraction through the first port while sealing before and after needleless extraction, with the access member and valve member formed from different materials and having planar portions whose outermost diameters are substantially the same. For the package embodiment, a housing secures the components such that the valve planar portion is positioned between the reservoir rim and the access planar portion.
