Abstract
A disposable unit- or multi-dose liquid dispensing container device, particularly adapted for delivery of ophthalmic liquid medicament in the form of discrete droplets to the eye. The structural configuration of the device including an angularly offset leading end permits the user to employ a free hand for manipulation of the eyelid to enhance reception of the discharge opening of the dispenser into the conjunctival cul-de-sac while at the same time, enabling the user to look directly into a wall-mounted mirror for accurate placement of the medicament. A small capacity reservoir and ease of control of accurate orifice size enables the application of uniform liquid-ejection pressure by the user to deliver droplets of reproducible dosage size with the multi-dose embodiment.
