1. A cartridge for spraying a liquid comprising:
a nozzle assembly, a liquid reservoir, and a cap attached to the liquid reservoir comprising at least one guide structure, wherein the cap is adapted to engage the nozzle assembly and allow for movement of the nozzle assembly in a controlled direction relative to the cap and the liquid reservoir, the controlled direction being defined by the at least one guide structure;
the nozzle assembly comprising a nozzle body, the nozzle body having an inner body and an outer body, the inner body being coaxial with the outer body, the inner body and outer body forming a first fluid passage therebetween, the first fluid passage adapted to deliver compressed air, the inner body comprising a second fluid passage in its interior, the second fluid passage adapted to deliver liquid from the liquid reservoir;
wherein the nozzle assembly is attached to the cap and the nozzle body, including the inner body and outer body, remains moveable in the controlled direction relative to the cap and the liquid reservoir while attached to the cap;
wherein the nozzle assembly is configured such that the liquid reservoir is initially sealed and when the nozzle assembly is moved in the controlled direction relative to the cap and the liquid reservoir, the movement of the inner body of the nozzle assembly relative to the cap pierces the sealed liquid reservoir to allow liquid from the liquid reservoir to flow into the second fluid passage of the nozzle assembly.
