Abstract
A closure is provided with channels through which wash water can be injected to wash out food particles between the threads of a container after the closure has been applied and sealed. In a composite closure embodiment, a lid or insert disk is received in an annular shell beneath an overhanging top lip of the shell. Water wash channels are provided on the undersurface of the top lip, and extend from the inner edge of the lip outwardly past the edge of the disk. One or more stops on the underside of the top lip prevent the channels from being closed, as by over-tightening. The wash channels extend outwardly past the stop, and communicate with a spiral channel in the threaded region of the shell, which in turn communicates with an outlet. A water jet directed onto the lid of the closure flows through the wash channels outwardly over the edge of the lid and downwardly into the threaded region, to an outlet.
