Bottle neck coupling device

A bottle neck coupling device for receiving in opposite ends the neck end openings of two bottles respectively and holding them in axial alignment so that one bottle can have its ingredients transferred to the second bottle by standing the one bottle upside down on top of the second bottle with their neck end openings held by said device, said device comprising, in combination:

• an outer annular body having integrally formed flexible fingers extending from opposite peripheral ends and a central partition;
• a tube section coaxially supported by said central partition at its mid portion so as to extend on either side of said partition within said body, said tube section having an outside diameter less than the inside diameter of said body to define an annulus therebetween on either side of the partition for receiving said neck ends of said bottles, the opposite ends of said tube section being received in the inside of the neck end openings and the annular body surrounding the outside of the neck end openings, said flexible fingers serving to hold the bottles in their mounted positions, said tube section holding the bottle neck end openings in coaxial alignment so that ingredients are transferred through said tube section by gravity.
