Abstract: A condition indicating child-resistant closure having an inner cap captivated within an outer cap wherein the caps are freely rotatable relative to each other when the closure is in the child-resistant mode, and are interconnected to each other for removal from a container when the closure is in the non-child-resistant mode. An indicating post is connected to the top wall of the inner cap and is adapted to be contained wholly within a space between the inner and outer caps and therefore not visible when the closure is in the child-resistant mode, the post being extendable through the top wall of the outer cap and therefore visible when the closure is in the non-child-resistant mode.

Abstract: A bottle closing cap is disclosed that is openable merely by a finger pressure on a domed top side of the cap, whereby it is possible to provoke an expansion of a depending, axially preslit cap skirt portion of the cap. The cap can resist overpressure in the bottle because the ends of the skirt segments are stabilized against overlapping, e.g. in that at each slit (6) they are shaped with respective counterphased edges (12,14). Hereby the caps will be mountable by a fully conventional equipment and, despite being easy to open, they will resist a considerable pressure in the bottles.

Abstract: Quick miosis with 24 hour control of intraocular pressure of patients undergoing extracapsular cataract extraction surgery is achieved by applying to the eyes of the patient during surgery acetylcholine as a first miotic agent and carbachol as a second miotic agent. Acetylcholine provides quick miosis while carbachol enhances the miotic effect while providing post-surgery control of intraocular pressure. The two miotic agents can be dissolved in a common saline carrier. The two agents can be combined in a unit dosage package by disposing acetylcholine in powder form in a first compartment and a solution of carbachol in a second compartment. The combined miotic agent of the invention is especially useful when substances which raise IOP such as viscoelastic agents are used during ocular surgery and/or with sensitive patients who enter the surgery with elevated pressure such as those suffering from glaucoma.
