Abstract
An aerosol valve has a body with a circular side wall extending down beyond the floor of the body to define a socket. Into this socket is frictionally engaged a symmetrical appendage having a circular upper end and a tailpiece at its lower end. The body is vertically partitioned into a primary product passage communicating from the tailpiece upward through an opening in the floor of the main valve. On the other side of the partition the lower end of the chamber is provided with a valve seat with an opening communicating with the primary passage. A side opening is formed through the appendage above the valve seat, and a ball is adapted to seat on the valve seat when the container is in normal position. When the container is inverted, the ball drops away from the seat and permits passage of product through the side opening, through the valve seat opening into the primary passage and up into the valve for discharge.
