A container sealing assembly is provided. The container sealing assembly includes a cap configured to attach to a container body and a unitary compliant sealing valve movable between a sealed position and an open position and configured to form a sealing interface with the cap when the unitary compliant sealing valve is in the sealed position. One or more seal-breaking structures may be provided to interact in response to a movement of the unitary compliant sealing valve from the sealed position to the open position, where such interaction is configured to break the sealing interface. A compression spring section of the valve may be provided to assist in moving the unitary compliant sealing valve into the open position.

Container sealing assembly

A container sealing assembly is provided. The container sealing assembly includes a cap configured to attach to a container body and including a sealing rib and a unitary compliant sealing valve having a continuous shape and movable between a sealed position and an open position. The unitary compliant sealing valve includes (i) a cap sealing section configured to form a sealing interface with the sealing rib when the unitary compliant sealing valve is in the sealed position and (ii) a compression spring section configured to exert a restoring force on a position adjustment member when the unitary compliant sealing valve is in the sealed position, the restoring force opposing a compressive force exerted by the cap and the position adjustment member on the compression spring section and urging the position adjustment member in an axial direction.

A gland member within a medical valve is configured to have a substantially consistent or enlarging internal volume as the valve transitions from a closed mode to an open mode. The valve has a housing forming an interior containing a flow path, and a stationary post member within the interior. The post member has a lumen that is a part of the flow path. The lumen has an opening to the interior of the housing. The valve further includes a gland member circumscribing the post member to produce a variable volume region formed at least in part between the gland member itself and the post member. The variable volume region is a part of the flow path, while the gland member occludes the post lumen opening when in the closed mode. The variable volume region has an open volume that is no less than its closed volume.

Anti-drawback medical valve

A container lid assembly configured to be used with and seal a container body is provided. The container lid assembly includes a container lid including a plug member extending downwardly and a gasket-retaining portion adjacent to and at least partially surrounding the plug member, where an outer surface of the plug member defines at least part of the gasket-retaining portion. The container lid assembly further includes a sealing gasket retained on the gasket-retaining portion and configured to provide a seal between the outer surface of the plug member and an interior wall of the container body, where the sealing gasket includes a pull tab that (i) extends away from a sealing portion of the sealing gasket; and (ii) extends downward away from the gasket-retaining portion of the container lid.

A medical valve includes a housing having an interior forming an inlet and an outlet. A longitudinally movable member is secured within the interior of the housing. External to the movable member and within the interior is a fluid path. Movement of the movable member controls fluid flow between the inlet and the outlet via the fluid path. The outlet produces no greater than a negligible drawback or positive push during withdrawal of a nozzle.

A gland member within a medical valve is configured to have a substantially consistent or enlarging internal volume as the valve transitions from a closed mode to an open mode. To that end, the valve has a housing forming an interior containing a flow path, and a stationary post member within the interior. The post member has a lumen that is a part of the flow path. The lumen has an opening to the interior of the housing. The valve further includes a gland member circumscribing the post member to produce a variable volume region formed at least in part between the gland member itself and the post member. In addition, the variable volume region is a part of the flow path, while the gland member occludes the post lumen opening when in the closed mode. The variable volume region has an open volume (i.e., when the valve is in the open mode) that is no less than its closed volume (i.e., when the valve is in the closed mode).

A medical valve having a close mode and an open mode includes a housing having a proximal end, a distal end, and an interior. The valve also has a valve mechanism within the interior. In illustrative embodiments, the valve mechanism has a gland member and a lifter member. The lifter member moves the gland member toward the proximal end of the housing as the valve transitions from the closed mode to the open mode.

Valve with internal lifter

A normally closed valve that may be opened upon insertion of a nozzle permits two-way flow when opened by a luer-taper nozzle. The valve also is able to resist large back pressures. The valve includes a substantially rigid housing that defines a passageway having an inlet section and an outlet section. The housing has an exterior inlet face to which the inlet section opens. The inlet section preferably has tapered and expanding zones. The tapered zone is adjacent to the exterior inlet face and is shaped to receive the nozzle. The expanding zone is adjacent to the tapered zone and has a larger inner diameter than the tapered zone's inner diameter. The exterior of the inlet section of the housing may have threads to accept luer-lock threads that may surround the nozzle.

Luer-activated valve

A medical valve has an interior flow path having a volume that is substantially the same when in either the closed mode (when the valve is closed) or the open mode (when the valve is open). To those ends, the medical valve has a housing forming an interior, and a valve mechanism (within the interior) having a substantially rigid translating member with a bore. The interior of the housing has a flow path that includes at least a portion of the bore of the translating member. As noted above, the open mode volume is substantially equal to the closed mode volume.

A medical valve has a resilient member that is forcibly expanded to an expanded volume from a normal volume. Specifically, the valve operates in a closed mode that prevents fluid flow, and an open mode that permits fluid flow. To these ends, the valve has a housing having an inlet and an outlet, and the noted resilient member within the housing. The resilient member and housing form a fluid channel between the inlet and the outlet. The fluid channel at least in part extends through the resilient member. The fluid channel has a given portion formed by a variable volume portion of the resilient member. The variable volume portion has a normal volume when in the closed mode, and an expanded volume when the open mode. The expanded volume is greater than the normal volume.

Medical valve with expandable member

A medical valve having an open mode to permit fluid flow and a closed mode to prevent fluid flow has a body and a valving element within the interior of the body. The body also has a valving element within its interior, and a proximal port and a distal port. The valving element controls fluid flow between the proximal and distal ports. Moreover, the valving element includes a resilient member and a plug. The resilient member forms a variable sized fluid chamber within the interior of the body, while the plug cooperates with the gland to provide an internal seal (within the interior of the body) that is spaced from the proximal port. The plug is capable of radially expanding the resilient member when the valve transitions from the closed mode to the open mode. The fluid chamber has a larger volume when in the open mode than when in the closed mode.
