A one time use non reusable sprayer includes a tank having a pump for pressurizing the liquid contents. A connection of the pump to the tank, if severed will result in destruction of the tank and pump to prevent reuse of the sprayer. The sprayer has a hose extending from the tank, a spray control valve and discharge nozzle for directing the spray.

A one time use non reusable garden and industrial sprayer comprising: a vertically upright plastic tank having an exterior and an interior for liquid to be dispensed under pressure, the tank having an inlet for filling the tank with the liquid and an outlet for the liquid contained in the tank and having a base adapted to rest on a horizontal surface whereby the tank is in an upright vertical position; pump means for forcing the liquid out the outlet under pressure, the pump means including a cylinder and piston movable in the cylinder, the cylinder being disposed in the tank and having an outer end, the tank having surfaces proximal the cylinder outer end; destructible connecting means for connecting the cylinder upper end to the proximal surfaces of the tank and being so constructed and arranged to destroy at least one of the cylinder upper end, the proximal surfaces of the tank and the connecting means so that the sprayer can not be reused; a hose having a proximal end extending from the tank outlet and having a distal end; a vertical supply tube having a lower end communicating with the tank interior and an upper end coupled with the hose; a control valve associated with the hose for controlling the amount of discharge of the liquid that is sprayed, the control valve including a handle having a passageway, the hose extending through the passageway of the handle, a movable arm on the handle adapted to be moved away from the hose and towards the hose to pinch the hose and restrict the flow of liquid therein; a discharge nozzle coupled with the distal end of the hose for the selected discharge pattern of the liquid to be sprayed; and venting means for preventing over pressurization of the tank interior.
