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.

Claims

1. A double ended bottle comprising:

a lateral wall;

an first neck having a first throat and a first mouth opening for discharging the contents of said bottle;

a second neck having a second throat and second mouth opening for discharging the contents of said bottle;

a first shoulder located between said lateral wall and said first neck;

a second shoulder located between said lateral wall and said second neck;

a single internal chamber extending between said first mouth opening and said second mouth opening;

a first cap having threaded engagement means for closing said first neck;

a second cap having threaded engagement means for closing said second neck;

said body having a longitudinal axis and a central plane located perpendicularly to said longitudinal axis, said central plane being disposed between said first shoulder and said second shoulder;

said both first and said second shoulders decrease in diameter from said central plane to said first and said second neck, respectively;

said single internal chamber having a chamber internal diameter, said first throat having a first throat diameter, said second throat having a second throat diameter, where said chamber internal diameter is at least twice the magnitude of both said first and said second throat diameter;

said first neck having a first neck outer surface including corresponding threaded engagement means for with said threaded engagement means of said first cap and said second neck having a second neck outer surface including corresponding threaded engagement means for with said threaded engagement means of said second cap;

said both first and second neck outer surfaces include a circular flange, said circular flange on said first neck located between said first shoulder and said corresponding threaded engagement means on said first neck, said circular flange on said second neck located between said second shoulder and said corresponding threaded engagement means on said second neck, and a corresponding groove is disposed on an interior of both said first and said second cap;

whereby

any leakage of contents from said single internal chamber is prevented by both said threaded engagement means and said circular flanges and said corresponding grooves.

2. The double ended bottle according to claim 1, wherein both said caps include an internal beveled projection dimensioned and configured to plug said first or said second throat when said cap is attached by said threaded engagement means.

3. The double ended bottle according to claim 1, wherein said bottle is fabricated from a material which is manually and resiliently deformable under manual pressure.
