Abstract: A hygienic dispensing package includes a container having a top panel with a dispensing aperture selectively covered by a slide closure. The closure rides within a flat channel of the top panel and is in tongue and groove engagement with parallel side walls of the channel. One of a pair of spaced sockets in the channel is engaged by a detent formed on the underside of the closure when the aperture is covered; the detent seats in the other socket when the aperture is uncovered. The detent is formed as a protrusion on an integral cantilever leaf of the closure to assure intimate sliding contact between the faces of the channel and the closure and effective sealing of the aperture.
