<p>When using containers of agricultural chemicals, such as herbicides, pesticides and the like, it is desirable to transfer the contents to the sprayer tank by pump means rather than physically lifting the container to the tank inlet and then pouring the contents manually into the tank. It is also essential to rinse out the container prior to disposing of same as most of the chemicals used are concentrated and can cause environmental damage if the majority of the contents are not removed prior to disposal. The present device allows the operator to transfer the chemical to the tank (10) by means of a pump (12) and then wash or rinse out the container with water which is then also transferred to the sprayer tank (10). A control valve portion (24) connects to a concentric tube assembly (23) which includes a container piercer (57) on the lower end thereof. The valve means (25A, 26A) may be manipulated to pump the chemical from the container to the sprayer tank (10) and to then pump water into the container and spray the interior thereof in order to thoroughly rinse same. The valves are then changed to pump the diluted chemicals into the sprayer tank (10). A flexible shroud (47) surrounds the conduits (30, 31) and is spring-loaded to retain same in contact around the area of the container in which the piercer (57) engages, in order to prevent concentrated chemicals from splashing the operator.</p> |
