Abstract

A spray or dispensing bottle is preferably blow molded from plastic material which is squeezable, with a sufficient plastic memory to cause the plastic to return to its original shape after it is squeezed and relaxed. The bottle includes an integral tube which extends from the bottom of the bottle, upwardly to the top of the bottle. Along the route of this tube, an aneurism or bladder is formed to receive and hold fluid which is sucked up the tube when the bladder is squeezed. Check valves are provided for opening and closing the fluid path from the bottle to the bladder and out of a nozzle. Thus, the bladder may be repeatedly pressed to create a vacuum, causing it to fill, or if squeezed when full, to spray the fluid out of the bottle. In one embodiment, a lever arm is positioned over the bladder in order to increase the mechanical advantage and relieve the stress which results if fingers must be used to squeeze the bladder.
