ABSTRACT:
The disclosure concerns a reinforced plastic bottle or vessel with a relatively large neck with buttressed threads and a bevelled rim on its neck onto which threads is screwed a cap assembly. This cap assembly comprises a plastic cap base member having an integral handle and a nozzle connection, a plastic manual air pump, a plastic siphon, a valve and spray nozzle assembly, and a lever to operate the valve. The air pump is supported by an integral flange and depends vertically from the cap base member into the bottle with a disc-type checkvalve at its bottom. This air pump is attached to the cap base by a piston-guiding cap having a pair of diametrically opposite resilient hooks that snap into slots in parallel walls of the cap base member on each side of the piston-guiding cap. Also depending from the cap base member is a plastic siphon tube with a plastic screen at its lower end, and the upper end of this siphon tube is connected to a fluid duct in the nozzle connection. An L-shape first class lever extends from the handle to a point above the nozzle connection and has a depending forked arm for operating a tubular valve slidably mounted in the nozzle connection through which tubular valve the spraying fluid is conducted. Around the outside of this tubular valve, separated from the fluid, is an helical compression spring that normally urges the tubular valve closed.
