Abstract
(EN)
A limited time use sprayer (10) includes a tank (12) having a pump (16) for pressurizing the liquid contents of the pump (16). The sprayer (10) has a hose (30) extending from the tank (12) for receiving liquid directly from the pump (16), a spray control valve (32) and discharge nozzle (38) for directing the spray. One or more parts from the pump (16) inlet to the discharge nozzle (38) are adapted to fail after a certain period of time with reuse of the sprayer (10).
