Abstract
A cap assembly includes an access member including a first section and a second section. The first section includes a connection portion that is attachable to an extraction device that extracts contents of a reservoir. The connection portion includes a first opening. The second section includes a second opening in fluid communication with the contents of the reservoir when the access member is secured to the reservoir. The cap assembly includes a valve member insertable into the access member so as to be in fluid communication with the first opening and the second opening and such that the valve member i) seals the contents of the reservoir at the first opening when the connection portion is not attached the extraction device, and ii) provides access to the contents of the reservoir through the first opening when the connection portion is attached to the extraction device.
Core Innovation
The invention relates to a needleless vial system that includes a cap assembly having an access member with a first section and a second section. The first section includes a connection portion having a first opening configured to be attachable to an extraction device, and the second section includes a second opening that is in fluid communication with vial contents when the access member is secured to the reservoir. A valve member is insertable into the access member so that it is in fluid communication with both the first opening and the second opening.
When the connection portion is not attached to the extraction device, the valve member seals the contents of the reservoir at the first opening. When the connection portion is attached to the extraction device, the valve member provides access to the contents of the reservoir through the first opening. In the inserted configuration, the valve member extends from the connection portion of the access member to the second opening of the access member.
The cap assembly further includes a sealing member that seals the reservoir-to-access-member interface, and a bendable hollow housing that secures the components. The valve member includes a slit-based compressible sealing/access behavior, where the slit seals in an uncompressed state and provides access in a compressed state when acted on by the extraction device tip. The connection portion may include male and female thread engagement to couple the cap assembly to the extraction device, and the housing may be formed from a bendable hollow cylinder such as an aluminum crimp.
Claims Coverage
The document includes three independent claims (cap assembly, vial assembly, and package). Across these claims, the inventive concept is implemented by combining an access member with first and second openings, an insertable valve member that seals versus provides access based on whether the connection portion is attached to an extraction device, and a structural arrangement in which the valve member extends to the second opening upon insertion.
Needleless cap assembly with insertable valve member that seals and provides access based on extraction-device attachment
A cap assembly including an access member with a connection portion attachable to an extraction device, the connection portion including a first opening, a second section including a second opening in fluid communication with contents when the access member is secured to the reservoir; and a valve member insertable into the access member to seal the contents at the first opening when the connection portion is not attached to the extraction device and to provide access through the first opening when the connection portion is attached.
Valve member extending to the second opening when inserted
When the valve member is inserted into the access member, the valve member extends from the connection portion of the access member to the second opening of the access member.
Vial assembly with reservoir and fixable cap assembly using an insertable valve member
A vial assembly including a reservoir to hold contents and a cap assembly fixable to the reservoir, the cap assembly including an access member with a first section including a connection portion attachable to an extraction device having a first opening, a second section having a second opening in fluid communication with the contents when the access member is secured to the reservoir, and a valve member insertable into the access member to seal the contents at the first opening when the connection portion is not attached to the extraction device and to provide access through the first opening when the connection portion is attached.
Package including reservoir, extraction device, and cap assembly with insertable valve member sealing versus access
A package including a reservoir to hold contents, an extraction device to extract the contents, and a cap assembly fixable to the reservoir, the cap assembly including an access member with a first section including a connection portion attachable to the extraction device having a first opening, a second section having a second opening in fluid communication with the contents when the access member is secured to the reservoir, and a valve member insertable into the access member to seal the contents at the first opening when the connection portion is not attached to the extraction device and to provide access through the first opening when the connection portion is attached.
Across the independent claims, the scope centers on an access member with first and second openings linked by an insertable valve member that seals the reservoir at the first opening when the connection portion is not attached to the extraction device and provides access through the first opening when attached, with the inserted valve member extending from the connection portion to the second opening.
