Trigger sprayer having a nozzle cover

A trigger actuated pump sprayer, comprising a housing having a first discharge passage in communication with a first liquid source and terminating in a first discharge orifice located in a first end wall, a cover hingedly connected to said housing for movement between an orifice uncovered position and an orifice covered position, said cover being connected to said housing by an over-the-center knee joint for urging said cover into the uncovered position, a first cylindrical sidewall extending upstream from said end wall and defining a first nosepiece together therewith, a first laterally extending circular seal ring on said nosepiece, and said cover having a first cup-shaped portion presenting a first cylindrical sidewall telescoped about said nosepiece forming a liquid tight seal with said seal ring in said covered position for sealing the discharge orifice closed.

A trigger actuated pump sprayer, comprising a housing having a first discharge passage in communication with a first liquid source and terminating in a first discharge orifice located in a first end wall, a cover hingedly connected to said housing for movement between an orifice uncovered position and an orifice covered position, a first cylindrical sidewall extending upstream from said end wall and defining a first nosepiece together therewith, a first laterally extending circular seal ring on said nosepiece, said seal ring comprising an annular downstream extending chevron seal diverging outwardly of said nosepiece, and said cover having a first cup-shaped portion presenting a first cylindrical sidewall telescoped about said nosepiece forming a liquid tight seal with said seal ring in said covered position for sealing the discharge orifice closed.
