Abstract
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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
198 words
Filed delivery equipment comprising: a container of the fluid to be delivered; an outlet fitting provided on the container; a supporting member adapted to receive the container in a releasable manner; an inlet fitting provided on the supporting member and adapted for releasable connection to the outlet fitting of the container; a delivery device carried by the supporting member; a duct connecting the inlet fitting to the delivery device; a releasable latching device, mounted on the supporting member for movement about a pivot axis, for retaining the container with respect to the supporting member; the latching device comprising first and second arms extending from the pivot axis, the first arm carrying an abutment element which abuts the container and the second arm carrying a latching element which makes latching engagement with the container to prevent removable of the container from the supporting means, the latching device constructed and arranged such that displacement of the latching element out of latching engagement with the container causes pivotal movement of the latching device resulting in displacement of the abutment means to move the container in a direction away from the supporting member to disconnect the inlet fitting from the outlet fitting.

Claim 9
Dependent Claim
24 words
Equipment as claimed in claim 1, in which the outlet fitting and the inlet fitting are engageable with each other by a push fit.
Claim 10
Dependent Claim
43 words
Equipment as claimed in claim 1, in which the interior of the container is divided by a flexible partition into two compartments, one of which communicates with the outlet fitting, and the other of which communicates with the surroundings through a vent hole.
Claim 11
Dependent Claim
23 words
Equipment as claimed in claim 9, in which the all of the container comprises two compartments, between which the flexible partition is secured.
Claim 12
Dependent Claim
26 words
Equipment as claimed in claim 10, in which the two components are substantially symmetrical with respect to each other about the plane at which they meet.
Claim 13
Dependent Claim
30 words
Equipment as claimed in claim 1, in which the supporting member is provided with a handset on which the delivery device is supported, the container being secured to the handset.
Claim 14
Dependent Claim
113 words
Fluid delivery equipment comprising: a handset; a delivery device carried by the handset on an elongate carrying member; a recess provided in the handset; a fluid supply duct extending from the handset to the delivery device through the carrying member; an inlet fitting on the fluid supply duct, which inlet fitting opens into the recess; a manually operable valve provided on the handset for controlling the flow of fluid in the fluid supply duct; a container for the fluid to be delivered, the container being releasably accommodated in the recess; an outlet fitting provided on the container and releasably engaging the inlet fitting; and releasable latch means retaining the container in the recess.
