ABSTRACT:
A plastic cap is used on containers, particularly of the type used commercially for five-gallon bottles containing liquids such as drinking water. A bead is formed on the exterior, preferably above the elevation of the horizontal tear line conventionally used in such caps. The bead is preferably flat on the outside surface and wide in a vertical sense. The bead functions to cause the cap to engage the neck of the container more securely. It also functions to retain in place a dust cap which fits over the top of the cap. It further functions as a seal for the type of cap used in certain water dispensers. Such dispensers are used without removing the cap from the container in that the top disk is opened after the container has been installed in the dispenser. The bead seals against the inside of a sleeve incorporated in such a dispenser.
