  • Publication number: 20130025703
    Abstract: An incorrect filling prevention assembly (10), including a body locatable in a filling guide tube so as to define a passage through the body coaxial with the guide tube.

A plurality of release members (48) are movably connected to the body so as to in a rest condition extend inwardly from the body into the body passage, and also in the rest condition retain the closure member (32) in the closed position. The release members (48) are movable outwardly relative to the body upon location of an item of sufficient diameter in the body passage to engage against a plurality of the release members (48) to move same to a use condition, with the release members (48) in the use condition allowing opening of the closure member (32).
