Abstract
A toy gun for projecting a fluent material. The gun has a front gun body and a hollow rear gun body, one having a cylinder as a part thereof and the other having a piston as a part thereof, the piston being slidable in the cylinder for a distance greater than the finger barrel of a user. A handle is provided on each of the gun bodies projecting laterally thereof for gripping the bodies for relatively moving them for moving the piston back and forth in the cylinder. An improved nozzle is provided on the piston or cylinder on the front gun body. An improved first one-way valve is connected to the nozzle for closing when the gun bodies are moved relative to each other for moving the piston out of the cylinder, and an improved second one-way valve is provided on the piston or cylinder on the rear gun body for closing when the gun bodies are moved relative to each other for moving the piston into the cylinder. A fluent material conduit is connected to the second one-way valve from within the rear gun body and this conduit has the rear end held in a lowered position to insure flow of fluent material into the cylinder.
