ABSTRACT:
A coupling of the present invention can be freely detachably attached to a flexible container whose outlet or opening is closed by a seal member broken by the tip of a male connector portion of the coupling. This coupling comprises a cylindrical body having at the tip thereof a hole for sucking fluid in the container, a valve seat formed in the cylindrical body, a valve body arranged in a fluid passing path communicated with the fluid sucking hole, and a spring for urging the valve body against the valve seat. When this coupling is attached to the opening of the container, the seal member by which the opening of the container is closed is broken by the tip of the cylindrical body. When a sucking pump is made operative to suck fluid in the container, therefore, the valve body is drawn against the spring to communicate the fluid passing path with the sucking hole, so that fluid in the container can be collected in a cup through the opening of the container.
