Foamer trigger dispenser with sealing device

摘要

The invention is particularly directed to a trigger sprayer having screen support structure for foaming a dispensed liquid where the support structure is comprised of a plurality of annular shoulders of varying diameters adapted to screens of differing diameters such that the distance between the nozzle and screen may be varied and thereby change the foam pattern of the dispensed liquid to obtain an optimum foam pattern for any particular liquid, and to the incorporation of a door connected with the sprayer nozzle housing for sealing the opening of a foam dispensing passage of the foamer trigger sprayer.
