Abstract: A coupling for use with comestible products having a first body with a first flow path extending therethrough and a second body with a second flow path extending therethrough. The first and second bodies are configured for coupling together such that the first and second flow paths form a continuous flow path through the coupling. The coupling further comprises a first valve member actuable between an open position, wherein product can pass through the first flow path, and a closed position, wherein the passage of product through the first flow path is prevented, and a first biasing member for biasing the first valve member into the closed position. The coupling is configured such that, if the first and second bodies become decoupled from one another, the first valve member is moved into the closed position. The first biasing member is isolated from the flow path passing through the coupling.

Abstract: A dry-break coupling comprising a spigot member and a complementary socket member to be attached to respective ends of two pipes to be coupled; the spigot member carries a valve member which is spring-loaded to close the mouth of the spigot member, and a valve member is carried by said socket member; fastening means are provided to urge the mouth of the spigot member into and secure the mouth in sealing engagement with the socket member, and operating means are provided to urge the socket valve member to close the socket member and alternatively to move the socket valve member forwardly to move the spigot valve member out of engagement with the mouth and so open the valves; first interlocking means are provided to permit actuation of the fastening means only when the spigot member is substantially fully inserted into a socket member, and second interlocking means are provided to permit actuation of said operating means only when said spigot members are secured together in sealing engagement by the fastening m
