ABSTRACT:
A double ended bottle having two narrow necks at opposed ends of the bottle. Sloped shoulders provide gentle transition between each neck and the full width of the body of the bottle. The bottle is internally open and unobstructed so that a common chamber extends from one opening to the other. Each neck has a threaded cap having two features for sealing against leaks past the cap. In one feature, an internal projection formed in each cap plugs the neck of the bottle. In an alternative embodiment, the neck has a separate adaptor or insert for reducing throat diameter. If this is provided, the projection is accordingly sized. Both the projection and the throat of the insert are beveled for centering the projection within the bore of the insert. The second sealing feature includes an external flange formed on each neck between the threads and the body of the bottle, and a corresponding groove formed in the cap. When each cap is fully threaded onto the bottle, the flange of the bottle seats within its respective groove. The caps are of diameters equal to that of the body, so that the bottle may be stood upright on a horizontal surface on either cap.
