Abstract
A dispenser suitable for storing and dispensing an opthalmic product and a method of dispensing the product into an occular cavity while maintaining the dispensing orifice of the dispenser free from contact with the occular cavity is described. The dispenser comprises a container with a cavity for containing a product to be dispensed, pump means, product dispensing valve means, and pressure equalizing valve means. A positioning/guard fixedly secured to the container cooperates therewith to positively position and anthroprometically locate the dispensing orifice relative to the occular cavity. The product is dispensed into the eye without loss of product due to inadvertent closing or blinking of the eye as a result of fear of a sharp object and also places the product properly for most effective results.
