Valve interconnector (1), suitable for use in combination with a receiver interconnector to couple a first hollow body associated to the valve interconnector to a second hollow body associated to the receiver interconnector, wherein the valve interconnector comprises a neck (7) to be secured to the first hollow body, a passageway (77) through the neck to allow fluid communication between the first hollow body and the second hollow body. The valve interconnector further comprises abase cap (8) secured to the neck, a valve assembly (5) secured to the base cap, the valve assembly being configured to assume at least a closed position and at least an open position. The valve interconnector further comprises a sealing ring (3) configured to provide a leakproof connection between the valve interconnector and the receiver interconnector. The valve interconnector further comprises a code ring cap (9), wherein the code ring cap (9) further comprises a head portion (99) covering at least a portion of the external surface of the head portion (89) of the base cap (8), the head portion (99) of the code ring cap (9) comprising a sealing ring enclosing portion (91) configured to cooperate in retaining the sealing ring (3) within the sealing ring seat (2).

A valve interconnector, suitable for use in combination with a receiver interconnector to couple a first hollow body to a second hollow body, is disclosed. The valve interconnector comprises a neck (7) to be secured to the first hollow body and further comprises a base cap (8) comprising an exterior tube portion (85) covering at least a portion of the external surface (7s) of the neck (7). The exterior tube portion and the neck are secured to each other with ability of relative rotation about a central axis. The valve interconnector is provided with a selector (44, 48) operative between the neck (7) and the exterior tube portion of the base cap (8) and configured for assuming at least a first position and a second position, in the first position the base cap being prevented from being axially released from the neck, in the second position the base cap being enabled to be axially released from the neck.

Fluid couplings described herein are designed to prevent spillage of fluid when connecting and disconnecting the couplings. In some embodiments, the fluid couplings described herein include internal valve components. In example embodiments, the fluid couplings are designed with minimal component parts and are designed for easy assembly so that the fluid couplings are economical to produce.

An aseptic coupling assembly, includes a first connector and a second connector. The first connector includes a first housing, a first valve member, and a first spring that biases the first valve member towards the second end of the first housing to a first closed position. The second connector includes a second housing, a second valve member, and a second spring that biases the second valve member towards the second end of the second housing to a second closed position. The first valve member is slidable away from the first closed position within the first housing to compress the first spring and the second valve member is slidable away from the second closed position within the second housing to compress the second spring. The coupling assembly further includes a seal that prevents fluid from contacting the first spring and the second spring.
