A container closure is provided with a body defining a dispensing orifice and a cover disposed on the body for being pivoted between a closed position occluding the orifice and an open position spaced away from the orifice. A hinge connects the cover to the body. The body has a generally smooth applicator surface around the dispensing orifice. The cover has an inwardly projecting sealing protrusion for entering at least partially into the dispensing orifice and sealingly engaging the body at the periphery of the dispensing orifice when the cover is in the closed position. The body and the cover together cooperate to define latching means, such as (1) an engagement between the protrusion and a portion of the body around at least part of the periphery of the orifice or (2) engaging ribs on the body and cover for releasably holding the cover in the closed position.

A container closure for use on a container defining an opening communicating with the container interior, said closure comprising: a body for being mounted to said container over said container opening and defining a dispensing orifice for communicating through said container opening with said container interior; a cover disposed on said body for being pivoted about an axis between a closed position occluding said dispensing orifice and an open position spaced away from said dispensing orifice; a hinge connecting said cover to said body for pivoting movement about said axis; said body having a generally smooth applicator surface around said dispensing orifice; said cover having an inwardly projecting sealing protrusion for entering at least partially into said dispensing orifice and sealinging engaging said body at the periphery of said dispensing orifice when said cover is in said closed position; said body and cover defining cooperating latching means for releasably holding said cover in said closed position; said dispensing orifice including a bore defined in said body by a generally cylindrical peripheral surface; said sealing protrusion including a plug member with a generally cylindrical side wall having a diameter greater than the diameter of said bore whereby said plug member is adapted to be matingly engaged with said bore peripheral surface to effect a leak-tight seal when said cover is in said closed position; said body being thinner around a portion of the periphery of said bore to permit flexing to accommodate insertion of said plug member; and said body being even thinner at the edge of said bore in said peripheral portion to facilitate subsequent removal of said plug member.
