This document describes devices and methods for reducing liquid spillage, such as fluid coupling devices that include one or more apertures that reduce spillage when the fluid coupling devices are disconnected. In some embodiments, the one or more apertures are designed with features to increase a level of acceleration that liquid within an internal volume of the fluid coupling devices would need to be exposed to in order to spill from the internal volume via the one or more apertures.

A valve connector includes a housing and a pressing device. The housing includes an operative end, a coupling end, and a through-hole extending from the operative end through the coupling end. The pressing device includes a push seat received in the through-hole and located between the lever and the coupling end and a lever abutting against the push seat and pivotably connected to the housing. The push seat includes a first passageway. The lever includes a second passageway and is operable to move the push seat. When the lever is in a release position, the first passageway does not intercommunicate with the second passageway. When the lever moves from the release position to a locking position, the push seat moves towards the coupling end, and the first passageway intercommunicates with the second passageway when the lever is in the locking position.

A quick connector and connector body comprises a coupler portion having a fluid passage connected to a first fluid tube. A valve mounted within the fluid passage is movable between a closed and an open position. A receptacle portion coupled to the coupler portion includes a socket cavity adapted to receive a second fluid tube within the socket cavity that causes the valve to move into the open position allowing fluid to flow through the fluid passage from the first fluid tube to the second fluid tube.

An O-ring membrane valve, including an O-ring, and a resealable membrane connected to the O-ring, the resealable membrane including a first surface, a second surface, and a slit extending from the first surface to the second surface. The O-ring membrane valve may be assembled with a fluid connector, the fluid connector including a body, having a first through-bore and a first groove arranged circumferentially within the first through-bore.

A fluid coupling includes a body, a poppet valve assembly, a handle shaft assembly, and a retention member. The body has a fluid conduit, a through-hole extending through a sidewall, and one or more openings that extend between an external surface of the body and an interior of the through hole. The poppet valve assembly is disposed within the fluid conduit and is selectively movable between an open position and a closed position. The handle shaft assembly extends through the through-hole and into the fluid conduit and is interconnected with the poppet valve assembly such that the handle shaft assembly can be actuated to move the poppet valve assembly between the open position and the closed position. The retention member is insertable through the one or more openings and into the through-hole to interact with the handle shaft assembly to selectively hold the handle shaft assembly in the body.
