Precision release eye dropper bottle

Abstract

An eye dropper bottle 20 is provided which allows a person to instill drops D into an eye E while the bottle 20 is held in a near horizontal orientation 22. The bottle 20 has a reservoir 51 for holding a liquid 59. The reservoir 51 includes a base 52, an upper end 50, and compressible walls 55. The bottle 20 further includes a neck 40 into which a dropper tip 34 fits. The neck 40 has external threads 42 onto which an internally threaded 32 cap 30 fits. The internal surface 56 of the walls 55 of the reservoir 51 maintains a constant slope 58 of a predetermined angle to allow virtually all the liquid 59 of the reservoir 51 to flow toward a dropper tip 34 where it can be discharged in the form of drops D while the bottle is held in a near horizontal orientation 22. The bottle 20 is grasped with a thumb T parallel to the length of the bottle 20 and an index finger F wrapped around a sulcus 48. The bottle is held in a near horizontal orientation over an eye E with the nail N of the thumb T resting against the upper bridge B of the nose. A predetermined distance 45 between a flange 44 and the distal end 36 of the dropper tip 34 causes the drop D to consistently and accurately align with an eye E. Drops D may also be instilled by holding the bottle 20 above and over an eye E in a near horizontal orientation 22.
