    Abstract: Disclosed herein are check valve assemblies with enhanced back flow protection. There are at least two duckbilled check valves, each having an inlet at one end and an elastomeric bill formed at an opposite end, the bill having opposed lips and an outlet openable by a flexing of the lips apart. The bill of the first duckbill check valve is telescoped into and retained in the inlet of the second duckbilled check valve (e.g. by a jam fit or snap fit connection). These assemblies can be positioned in compact conduits such as those found in garden hose outlet nozzles.

    Abstract: A device for that places a fluid container in fluid communication with a sprayer is disclosed. The device includes a container adapter that allows a dip tube to be attached to the fluid container rather than the sprayer. When the sprayer is removed from the fluid container, the dip tube stays in the fluid container. Refill fluid containers may come with the container adapter and dip tube installed. When the sprayer is attached to the fluid container, the adapter seals against the sprayer allowing fluid to be pumped from the fluid container by the sprayer. A sprayer connector with geometry that matches an inner or outer shape of the adapter is attached to and/or built into the sprayer. The sprayer connector is constructed to allow easy alignment of the sprayer to the fluid container. The sprayer connector and the container adapter also provide a unique attachment geometry to insure only containers with formulae compatible to the sprayer are pumped through the sprayer.
