Abstract
A dispenser has a hollow housing with sidewalls, a base and a top. The top has a cylinder for receiving piston, and a catch for permitting limited movement of the piston within the cylinder. The piston having an inlet valve for allowing air into the cylinder. The cylinder has an outlet valve which forces air into the housing. The dispenser has a tri-purpose nozzle. The nozzle has a dispensing orifice at one end and is biased in an open up position. The piston is suspended from the bottom surface of the nozzle. As such, the nozzle acts as the pump for slidably moving the piston within the cylinder. The top has a fluid outlet port opposite the position of the cylinder. The nozzle is rotatably connected to the top. In addition, there is a structure for fluidly connecting the fluid outlet port to the nozzle. That is, when the nozzle is pumped downward, the nozzle is aligned with the fluid outlet port via the structure for fluidly connecting so as to permit a fluid to travel from the housing, through the fluid outlet port, through the structure for fluidly connecting, through the nozzle and out the dispensing orifice. When the nozzle springs back to its resting position, the nozzle and fluid outlet port are not in alignment, thereby preventing air and fluid from flowing out the housing. The nozzle and structure for fluidly connecting thus acting as a valve.
