Google patents eye dropper attachment that uses liquid to show level position

1. An apparatus for assisting with alignment of a dropping nozzle of an eye dropper bottle, the apparatus comprising: a tubular hub configured for selective engagement with the dropping nozzle to selectively laterally surround the dropping nozzle within a hub lumen thereof; a first semispherical disc having a first center aperture and a first disc rim, spaced radially apart from the first center aperture by a first disc body, the first center aperture laterally surrounding an outer wall of the tubular hub, and the first disc body being semispherically curved between the first center aperture and the first disc rim; a second semispherical disc having a second center aperture and a second disc rim, spaced radially apart from the second center aperture by a second disc body, the second center aperture laterally surrounding the outer wall of the tubular hub at a location thereupon longitudinally spaced from the first center aperture, and the second disc body being semispherically curved between the second center aperture and the second disc rim; wherein the first and second disc rims are attached together at a rim perimeter to laterally enclose a substantially fluid tight toroidal indicator space longitudinally between the first and second disc bodies and radially between the outer wall of the tubular hub and the rim perimeter; and wherein at least one user-perceptible liquid is located within the indicator space, the liquid shifting with respect to the tubular hub under influence of gravity responsive to an angular position of the tubular hub, wherein the first disc body comprises an inner surface and a outer surface, the inner surface positioned closer to the second disc body than the outer surface, the inner surface at least partially defining a cavity, wherein the second semispherical disc is positioned entirely within the cavity in a manner that the second disc rim does not extend past the first disc rim.
