Total Claims: 6
Claim 1
Independent Claim
165 words
In combination, an eye drop dispenser including a compressible plastic container for the drops to be dispensed and an elongated, small diameter tubular dispensing member communicating with said container and having a dispensing orifice spaced therefrom, and a device for illuminating said dispensing orifice, said device comprising: (a) a body member, (b) a self-contained energy source carried by said body member, (c) a light source mounted to said body member at a position located away from said dispensing orifice to provide an unobstructed area along a major portion of said tubular dispensing member, said light source being capable of projecting a collimated beam of light, (d) a switch carried by said body member, said switch being operable to selectively connect said energy source to said light source, and (e) aligned surfaces forming a channel-way receiving said container to provide a stable orientation of said container with respect to said device while permitting shifting movement therebetween in a direction generally aligned with said tubular dispensing member.
