  • Patent number: 4606477
    Abstract: The disclosure concerns a reinforced plastic bottle or vessel with a relatively large neck with buttressed threads and bevelled rim on its neck onto which threads is screwed a cap assembly. This cap assembly comprises a plastic cap base member having a pair of parallel ribs forming a channel between an integral handle and a nozzle connection, a plastic manual air pump, a plastic siphon, a valve and spray nozzle assembly, and a lever disposed in said channel 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 said channel in the cap base member on each side of the piston-guiding cap.
