Abstract: A container for liquid such as herbicide has a internal flexible partition dividing the interior of the container into two compartments, one of which is liquid filled and communicates with an outlet, while the other communicates with the surroundings through a vent hole. The wall of the container has recesses for engagement by latching elements of delivery equipment to retain the container with respect to the delivery equipment.

Abstract: Equipment for delivering a fluid, such as herbicide, comprises a carrier (2) in the form of a handset and a support tube (4) which is connected to the carrier (3) and carries a distribution head. A supply duct (6) conveys herbicide from the carrier to the distribution head, and electrical leads (8) provide a connection between a battery, mounted in the carrier, and a motor in the distribution head. The support tube (4) has a connector (10) which is secured to the carrier by a screwthreaded sleeve. A spigot (18) of the connector 10 enters a bore in a valve to provide sealed connection between the valve and the supply duct (6). First contacts (28) on the connector (10) engage second contacts (42) in the carrier to provide electrical connections. The support tube (4) can thus be coupled to the carrier (2) by a simple plug in operation.

Abstract: Equipment for delivering fluids such as herbicides comprises a handset which supports delivery means such as a spraying head on a support tube 4. The handset receives a container 134 of fluid which is to be distributed, this container being received within a cavity 132 in the handset. The container is retained within the cavity 132 by latching elements 166 provided on a pivotable lever 162. As the container 134 is inserted into the cavity 132, the container engages a cam 168 which causes the lever 162 to pivot into the engaged position. An outlet fitting 150 provided on the container is automatically engaged with an inlet fitting communicating with a supply duct 10 for supplying fluid from the container to the spraying head.
