A spray head is disclosed having an aligned fluid conduit leading respectively to a source of pressurized water and a spray outlet. A rotatable, vertically movable valve element lies in a suitable bore in the spray head between the conduits. The valve has a horizontal conduit therethrough which merges with a vertical conduit adapted to convey liquid from a container to which the spray head is connected. A frangible locking collar lies between the head of the valve and the upper surface of the spray head holding the valve from either rotational or vertical movement towards the container. Breaking and removal of the locking collar allows for 90°rotation of the valve to unseat inwardly from a flange carried by the valve body from inwardly projecting retaining flanges carried by the spray head body thereby allowing for downward movement of the valve to puncture a seal over the container holding the liquid. This downward movement also brings the conduit in the valve into the same plane as the two conduits in the spray head. Rotation of the valve 90°back to its original orientation aligns and interconnects all the conduits making the system ready for use upon activation of the source of pressurized water.

A spray head for mixing pressurized water with a liquid held in a container with a seal to which the head is adapted to be attached and providing a spray thereof which comprises: (a) a cap member having fluid conduit means therein which respectively are adapted to communicate with (i) a source of the pressurized water; and (ii) an outlet for the spray; (b) a rotatable valve located in a bore between the fluid conduit means in the cap member which valve is adapted, upon rotation and movement towards the sealed container to unseal the container and also achieve intercommunication of the source of pressurized water and the outlet for the spray through the fluid conduit means in the cap member and an aligned fluid conduit means in the valve, which valve has additional conduit means connected to said aligned fluid conduit means, which also communicates with a fluid conduit for the liquid in the container to be contained in the spray, thereby allowing liquid to be aspirated into the valve from the container through a neck on the container to mix with the pressurized water and produce the spray when the fluid conduit means in the cap are intercommunicated with the aligned fluid conduit means in the valve; and (c) a frangible locking collar holding and preventing the valve from both rotation and movement towards the container except after the collar has been broken and removed from the valve.
