Method of, and dispenser for introducing an opthalmic product into the occular cavity
First Claim
1. The method of introducing an ophthalmic product from a dispenser into an occular cavity whereby blinking is substantially eliminated and the dispensing orifice of the dispenser does not contact said occular cavity, said dispenser comprising a container having wall means defining a cavity for containing a product to be dispensed, a dispensing orifice positioned in said wall means and in fluid communication with said cavity, and pump means constructed and arranged with said cavity to develop sufficient internal pressure within said cavity to dispense product from said cavity through said orifice, and a generally ring-shaped positioning/guard means fixedly secured to said container means and generally encircling said dispensing orifice, said positioning/guard means being angularly displaced relative to the longitudinal axis of the container, said method including the steps of positively positioning the generally ring-shaped positioning/guard means of the dispenser around the occular cavity thereby anthroprometically locating the dispensing orifice relative to said occular cavity while maintaining the dispensing orifice free from interference with the normal line of sight and activating the pump means of said dispenser to dispense an effective amount of ophthalmic product into said occular cavity.

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.

6. A dispenser suitable for introducing an ophthalmic product into the occular cavity comprising --
a. container means comprisingwall means defining a cavity for containment of the product to be dispensed; -
2. a dispensing orifice positioned in said wall means and in fluid communication with said cavity; and 3. a pump means constructed and arranged with said cavity to develop sufficient internal pressure within said cavity to dispense product from said cavity through said orifice; and b. a generally ring-shaped positioning/guard means fixedly secured to said container means and generally encircling said dispensing orifice wherein said positioning/guard means is angularly displaced relative to the longitudinal axis of the container means such that when said positioning/guard means is placed around the occular cavity said dispensing orifice can be anthroprometically located relative to the occular cavity while avoiding contact with said occular cavity and interference with the normal line of sight. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
