Abstract

An eyedrop dispenser for dispensing droplets of liquid from a container comprises a closure cap member for liquid tight attachment to the container. At least one projection extends laterally outward from the cap member and has a laterally outward facing surface for bracing against a portion of the head of a person to locate and steady the dispenser during use.

Claims

1. A device for dispensing droplets of a liquid from a container having an open neck end, said device comprising a closure cap member for liquid-tight attachment to the neck end of the container, an outwardly projecting generally elongated, straight tubular member of small diameter extending along an axis endwise from the cap member and terminating in an outer tip end, said tubular member having an inner passageway communicating said tip end with the interior of the container, and at least one projection integrally formed with and extending outwardly from said cap member having a laterally outward facing rest surface thereon, said projection extending from its point of attachment to said cap member laterally outwardly and away from said tip end in a direction parallel to said axis, whereby said surface is located in predetermined spacial relation from said tip end of said tubular member, said rest surface being of generally arcuate shaped form with its center of curvature located adjacent said axis at a point spaced from said cap member in a direction opposite to the direction in which said tubular member extends from said cap member, whereby said surface can be braced against a portion of the head of a person such that accurate locating and steady holding of the tip end of the dispensing nozzle in a desired proper droplet dispensing use position can be attained.

2. A device for dispensing droplets of a liquid from a container having an open neck end, said device comprising a closure cap member for liquid-tight attachment to the neck end of the container, an outwardly projecting elongated, generally straight tubular dispenser member of small diameter extending along an axis endwise from the cap member and terminating in an outer tip end, said member having an inner passageway communicating said tip end with the interior of the container, and two projections integrally formed with and extending outwardly from said cap member, each having a laterally outward facing rest surface thereon, said projections displaced from said dispensing tip along said axis and extending generally laterally outwardly from said axis, whereby said surfaces are located in predetermined spacial relation to the tip end of said dispenser member, one of said projections having a laterally outward facing generally flat planar surface disposed in a plane generally parallel to the axis of said dispenser member, and the other of said projections extending from its point of attachment to said cap member laterally outwardly and away from said tip end in a direction parallel to said axis, said other of said projections having a rest surface of generally arcuate shaped form facing in a direction laterally outward of said cap member and with its center of curvature located adjacent said axis of said dispenser member at a point spaced from said cap member in a direction opposite to the direction in which the said dispenser member projects from said cap member, whereby each of said surfaces can be individually braced against a portion of the head of a person such that accurate locating and steady holding of the tip end of the dispensing nozzle in a desired proper droplet dispensing use position can be attained.
