A device in the form of a collar has opposite end openings for receiving the neck end openings of two bottles such as ketchup bottles to hold them in axial alignment. With this arrangement, one bottle can have its ingredients transferred by gravity to the other bottle by standing the one bottle upside down on top of the second bottle. The collar device holds the bottle necks in proper alignment, so that the transfer of ingredients can take place.
