Patent ID: 8544686

Claim:
A system for dispensing sprayable material comprising: a flexible container having a body, a bottom and a top forming an exterior surface and an interior space within which a material is housed and further comprising a spray tip mounted on a valve through which the sprayable material is sprayed; a dispenser configured to exerting pressure on the flexible container to force the sprayable material through the tip, the dispenser comprising: an elongated housing formed with an interior portion; a movable panel on the elongated housing wherein in an open position the interior portion is exposed through which the flexible container is placed in the interior portion, and in a closed position an interior surface of the housing and an interior surface of the movable panel form a rigid enclosure contacting the exterior surface of the flexible container and counteracting pressure exerted on the flexible container; a fixed plate forming a first end of the housing with a valve seat in which the valve is seated; a piston positioned inside the housing with a first end attached in slidable contact with the bottom of the container; a plunger extending through a second end of the housing into the interior portion of the housing and attached to the piston; a biasing element in movable connection with the piston wherein the biasing element biases the piston against the bottom of the container; a handle attached to the housing; a movable first trigger affixed to the housing, wherein movement of the first trigger slides the plunger within the housing exerting force on the bottom of the container; and a moveable second trigger mounted to the housing, wherein movement of the second trigger opens the spray tip releasing the sprayable material from the container.
