To overcome shortcomings of the prior art, the subject invention is provided which includes various dropper bottle designs and dropper bottle assemblies including accessories for dropper bottles. With certain aspects of the subject invention, improvements in the administration of eye drops is provided by adding accessories or modifications to conventional dropper bottles, so that doses and/or single drops may be administered in a repeatable and reliable manner. More specifically, certain embodiments use devices (10, 300) to restrict the amount the dropper bottle (12) is deformed in administering a dose; other embodiments rely on mechanical reduction of interior volume (without deformation of the dropper bottle (12)) to administer a dose, such as with a displaceable piston (500, 602); and, yet, a further embodiment provides a valving arrangement (402, 404) to limit a dose. Features (200) are also included which aid in the alignment of the dropper bottle's nozzle to the eye, and a feature (102) is provided for protecting the user's eye from potential damage which can occur if a pointed nozzle (104) is brought into contact with the eye during alignment. As will be appreciated by those skilled in the art, the various aspects and embodiments disclosed herein may be used singularly or in various combinations.

What is claimed is: 1. A dropper bottle assembly comprising: a dropper bottle including an interior volume; and, a cradle mounted to said dropper bottle, said cradle including a movable lever arm, wherein movement of said lever arm causes a first portion of said lever arm to deform said dropper bottle in reducing said interior volume of said dropper bottle, whereby reduction of said interior volume causes fluid to be administered from said dropper bottle, wherein said cradle includes a second portion defining a recess, and a second portion being formed on said lever arm to nest within said recess upon a predetermined extent of movement of said lever arm. 2. An assembly as in claim 1, wherein said second portion of said lever arm creates an audible signal upon nesting within said recess. 3. An assembly as in claim 1, said lever arm being hingedly connected to said second portion of said needle by a hinged connection. 4. An assembly as in claim 3, wherein said hinged connection urges said lever arm to a rest position where said dropper bottle is undeformed or substantially undeformed. 5. An assembly as in claim 3, wherein said lever arm includes a free end, said first portion of said lever arm being located intermediate said hinged connection and said free end. 6. An assembly as in claim 3, wherein said second portion of said cradle includes an aperture, said dropper bottle including a neck, said aperture being larger than said neck. 7. An assembly as in claim 6, wherein said first portion of said lever arm being formed to pressingly engage said dropper bottle to cause a portion of said neck to pressingly engage said second portion of said cradle located adjacent said aperture. 8. An assembly as in claim 1, wherein said dropper bottle includes an indented bottom surface, said second portion of said cradle being formed to seat within and press against said indented bottom.
