Tilt action mixing dispenser valve

Abstract

Abstract A tilting type dispensing valve comprising a cup-shaped valve housing which is covered by a resilient upper annular dischargevalve seat. A hollow valve stem extends through the valve seat and carries an annular valve shoulder inside the housing. The shoulder is engageable with the seat to close off the discharge. Within the housing there is a supporting boss constituting a second valving means on the valve stem, said boss being located below the valve shoulder and being engageable with a recessed lower annular valve seat in an opposite wall of the valve housing to both normally maintain the valve shoulder and upper seat engaged whereby the upper valve is closed, and to simultaneously close the recessed lower valve seat. The stem can be tilted, however, because the shoulder can compress a localized area of the upper valve seat. This separates another portion of the shoulder from the seat whereby liquid can flow from the housing, out through the hollow valve stem. The tilting of the stem also uncovers the lower valve seat. A container connected to the lower valve seat can empty into the valve housing, as well as a large container enclosing the housing, which discharges into the housing through a hole provided in a wall of the housing. Mixing of the liquids occurs in the valve housing.
