Abstract:
1. An eye drop dispensing attachment comprising: a) a base portion, said base portion having an inner wall and an outer wall defining a circular base interior region, said base having a top end and a bottom end, said inner wall having a plurality of circumferential threads for rotatable attachment to a bottle; b) a lower neck portion connected to said top end, said lower neck portion having an inner wall and an outer wall defining a circular lower neck interior region having a smaller diameter than said base interior region, said lower neck portion having a lower neck top end and a lower neck bottom end; c) an upper neck portion connected to said lower neck top end, said upper neck portion having an inner wall and an outer wall defining a circular upper neck interior region having a smaller diameter than said lower neck interior region, said upper neck portion having an upper neck top end and an upper neck bottom end; and d) a tip connected to said upper neck top end, said tip being tubular in shape and having dimensions to produce liquid drops having between 5-12.5 micro-liters volume wherein said tip further includes a needle portion extending into said base interior region, said needle portion comprised of a hollow tube having a sharp point at the distal end thereof, whereby when the eye drop dispensing attachment is removably attached to a bottle containing liquid-resistant diaphragm barrier, said sharp point penetrates the diaphragm barrier and allows liquid from the bottle to flow through said needle portion to said tip whereby when the eye drop dispensing attachment is securely attached to a bottle containing liquid, a user inverts the bottle, causing liquid to enter said base portion, said lower neck portion, said upper neck portion, and said needle portion and said tip, wherein a drop of liquid of a specified volume forms around the outer opening of said tip, and a user can position said tip over a location where the drop is to be applied, such as an eye.
