Abstract

Abstract An eyelid engaging device for mounting on a threaded or tapered neck of an eyewash container when the cap that normally engages said neck is removed therefrom. If desired, the device may be formed as an integral part of the neck. The neck has an aperture in the free end extremity thereof through which eyewash may be dispensed drop-by-drop into an eye when the container is supported in an inverted position. When the container is supported in the dispensing position, the eyelid-engaging device frictionally contacts the eyelid to maintain it in an open position as drops of the eyewash are directed into the eye.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 278 words
In combination with an eyewash container having a neck in which a dispensing aperture is defined from which eyewash will discharge drop by drop downwardly by gravity when said container is held in an inverted position, said neck having external threads on at a portion thereof intermediate said aperture and said container and an internally threaded cap that removably engages said threads of said neck to completely envelop said aperture and the portion of the neck adjacent thereto protect them and the eyewash in said container from contamination when said container is not in use, an eyelid engaging device, said device including: a. a ring that engages said threads on said neck; b. a boss extending outwardly from said ring; c. a single curved upright supported by said boss and extending upwardly and inwardly relative thereto, said upright transversely spaced from said threads on said neck sufficiently as to permit said cap to be screwed on and unscrewed from said neck; and d. a transverse eyelid-engaging member supported from the upper end of said upright, said member being arcuately curved to permit said member to be brought into light frictional contact with an eyelid of a user to maintain said eyelid in an open position when said container is in an inverted position and the head of the user is tilted rearwardly, and said upright being of such length as to dispose said aperture directly above said eye when said eyelid is so contacted to permit drops of the eyewash to fall by gravity into said eye, with said cap capable of being secured on and unscrewed from said neck while said device remains mounted on said container.
Claim 2
Dependent Claim 278 words
In combination with an eyewash container having a neck in which a dispensing aperture is defined from which eyewash will discharge drop by drop downwardly by gravity when said container is held in an inverted position, said neck having external threads on at a portion thereof intermediate said aperture and said container and an internally threaded cap that removably engages said threads of said neck to completely envelop said aperture and the portion of the neck adjacent thereto protect them and the eyewash in said container from contamination when said container is not in use, an eyelid engaging device, said device including: a. a ring that engages said threads on said neck; b. a boss extending outwardly from said ring; c. a single curved upright supported by said boss and extending upwardly and inwardly relative thereto, said upright transversely spaced from said threads on said neck sufficiently as to permit said cap to be screwed on and unscrewed from said neck; and d. a transverse eyelid-engaging member supported from the upper end of said upright, said member being arcuately curved to permit said member to be brought into light frictional contact with an eyelid of a user to maintain said eyelid in an open position when said container is in an inverted position and the head of the user is tilted rearwardly, and said upright being of such length as to dispose said aperture directly above said eye when said eyelid is so contacted to permit drops of the eyewash to fall by gravity into said eye, with said cap capable of being secured on and unscrewed from said neck while said device remains mounted on said container.
Claim 3
Dependent Claim 20 words
The eyelid-engaging device as defined in claim 1 that is molded as an integral unit from a polymerized resin material.
