Patent ID: 8789728

Claim:
A bottle insert comprising: a coupling portion configured to asymmetrically contact an inner surface of a neck of a spray dispenser, the coupling portion preventing substantial movement of the bottle insert relative to the spray dispenser, the coupling portion having an upper annular portion and a lower annular portion laterally offset from each other such that the upper annular portion contacts only a first region of the inner surface and the lower annular portion contacts only a second region of the inner surface, the first and second regions of the inner surface occurring at different elevations and different sides of the inner surface of the neck of the spray dispenser, and wherein contact of the upper and lower annular portions with the inside surface of the neck gives the coupling portion an effective diameter substantially equal to an inner diameter of the neck of the spray dispenser and thereby braces the coupling portion to prevent rotation thereof within the neck of the spray dispenser, the effective diameter being greater than a diameter of the upper annular portion alone and greater than a diameter of the lower annular portion alone; and a guide portion coupled to a bottom of the lower annular portion of the coupling portion and configured to descend into a body of the spray dispenser, the guide portion shaped so as to bend a flexible suction tube of a cap of the spray dispenser towards an off-center portion of a bottom of the body of the spray dispenser, the flexible suction tube passing through the bottle insert to the cap.
