  • Patent number: 6257451
    Abstract: A manually actuated pump sprayer has a cover on the plunger head which is shifted relative thereto, the cover having an opening for exposing the discharge orifice when relatively shifted. In a non-use condition a portion of the cover side wall fluid tightly seals the orifice closed by engaging a circular seal bead provided on the outer face of the orifice cup concentric with the orifice. The outer face of the orifice cup may be textured to increase the hang time of any residual liquid product at that area which is likewise prevented from drying to avoid clogging by the sealed condition presented between the cover and the circular seal bead in the non-use position.
