Abstract
The present invention is an invertible eye drop dispenser device, alone, and in conjunction with an eye drop dispenser container having a threaded neck. The device includes a hollow, circular base portion with a bottom end and a top end. The bottom end has a first set of internal threads and the top end has a second set of internal threads, both being of the same thread gauge, to thread onto a neck of an eye drop dispenser container. The first set of internal threads and the second set of internal threads are inverted relative to one another, so that the device may be threaded with the bottom end threaded to a container or, so that, upon inversion, the device may be threaded with the top end threaded to a container. There is also an eye cup portion attached to the bottom end of the base portion.
