Abstract
Liquid delivery apparatus includes a container 138 for the liquid, the container 138 having a liquid outlet 150 for dispensing the liquid and a vent hole 53 for admitting air to the container 138 to replace dispensed liquid. The vent hole 53 is closed by a closure element 56 which is removable to expose the vent hole 53. When fitting the container 138 to a delivery device 2, the closure element 56 engages the delivery device 2 so as to remove the closure element 36 automatically to cause the vent hole 53 to be exposed.
