ABSTRACT:
A coupling system for transferring granular contents from a container to a pump dispenser with minimum risk of direct contact with a user. The coupling system includes a connecting threaded assembly that is frictionally and snugly mounted inside the neck of the container. The upper wall of the connecting threaded assembly includes at least one off-centered opening. A cap assembly is rotatably and coaxially mounted over the connecting threaded assembly and the former also includes at least one off-centered opening that is selectively made to coincide with the off-centered opening of the connecting threaded assembly. A spring is used to bias these two assemblies to make the respective off-centered openings not to coincide. A coupling ring assembly is firmly mounted inside the neck of a pump dispenser. The cap assembly engages the coupling ring assembly with at least one of its protuberances that extend radially outwardly into the L-shape slots on the internal surface of the coupling ring assembly. A gasket member is used to achieve a hermetic sealing engagement between the dispenser and the container. Eyed tabs cooperatively and rigidly mounted on the container's frustroconical portion and the connecting threaded assembly permit the use of sealing wires. A user can dispense granulated material from the container to a dispenser by achieving a hermetically sealed engagement without coming in contact with the material.
