ABSTRACT:
A liquid dispenser for eye drops, antiseptic solutions and the like, comprises a dispensing cap having a projecting conical discharge spout with tapered side walls and an annular end wall that surrounds the orifice. Projections in the form of ribs are provided on the exposed surfaces of the spout, to minimize the likelihood of contamination of broad spout surfaces if the spout inadvertently comes in contact with exterior objects. The projections are on both the end and the side surfaces of the spout.
