Fluid coupling valve assembly

A method of dispensing fluids comprising:

• providing a closure, wherein the closure includes a closure body and a closure valve, wherein the closure body and the closure valve are rotatably connected to each other, the closure body having a sleeve portion with an opening and a fitment extended outwardly from a side of the sleeve portion, the closure valve having an opening corresponding to the opening of the sleeve portion of the closure body, and a closure handle, wherein the closure handle rotates the closure valve relative to the closure body between an open configuration and a closed configuration and providing a coupler, wherein the coupler includes a coupler body and a coupler valve, wherein the coupler body and the coupler valve are rotatably connected to each other, the coupler body having a projecting edge and an opening extended from a side of the coupler body, the coupler valve having an opening corresponding to the opening of the coupler body and a coupler valve handle, wherein the coupler valve handle rotates the closure valve relative to the coupler body between an open configuration and a closed configuration, and the coupler valve handle having an engagement pocket;
• connecting the closure and the coupler, wherein the engagement pocket of the coupler valve handle engages the closure handle connecting the closure and the coupler;
• attaching the closure to a fluid source and attaching the coupler to a fluid system;
• simultaneously rotating the closure handle and the coupler valve handle, thereby actuating an open or a closed configuration of both the closure and the coupler to permit or prevent dispensing of a fluid;
• retaining connection between the closure and the coupler through an end of the closure handle engaged to the projecting edge of the coupler, thereby preventing the closure and coupler from pulling apart while rotating the closure and the coupler to the open or the closed configuration;
• and
• interlocking the closure handle and the coupler valve handle through an interlock on the projecting edge engaged to the end of the closure handle.

A fluid coupling valve assembly comprising:

• a closure including a closure body and a closure valve, wherein the closure body and the closure valve are rotatably connected to each other, the closure body having a sleeve portion with an opening and a fitment extended outwardly from a side of the sleeve portion, the closure valve having an opening corresponding to the opening of the sleeve portion of the closure body, and a closure handle, wherein the closure handle rotates the closure valve relative to the closure body between an open configuration and a closed configuration;
• and
• a coupler including a coupler body and a coupler valve, wherein the coupler body and the coupler valve are rotatably connected to each other, the coupler body having a projecting edge and an opening extended from a side of the coupler body, the coupler valve having an opening corresponding to the opening of the coupler body and a coupler valve handle, wherein the coupler valve handle rotates the coupler valve relative to the coupler body between an open configuration and a closed configuration, and the coupler valve handle having an engagement pocket, wherein the engagement pocket of the coupler valve handle engages the closure handle connecting the closure and the coupler;
• and
• wherein the closure handle and the coupler valve handle rotate simultaneously in an open or close configuration.

A fluid dispensing system comprising:

• a fluid source;
• a coupling valve assembly including a closure actuatable between an open and a closed position and a coupler actuatable between an open and a closed position, the coupler being rotatably connected to the closure, the closure and the coupler including a retention mechanism retaining the closure and the coupler in a coupled state;
• the retention mechanism including the closure having a closure handle including an end, said end is a protruding end, and including the coupler having a projection edge thereon said coupler;
• the protruding end and the projection edge are in communication rotating the fluid coupling valve assembly in a open or closed position,
• wherein the coupler and the closure can only be separated when both the closure and the coupler are in a closed position;
• and
• a fluid line attached to the coupler.
