Abstract
A hand-operable system for ejecting a fluid composition into an eye, the system including: (1) a container having a container opening and containing the fluid composition; (2) a double-acting pump mechanism securely disposed over the container opening; and (3) an actuator that is disposed over, and extends radially outward from, the pump mechanism, for actuating the pump mechanism by applying a force thereon, wherein the pump mechanism includes a passage for the fluid composition, and the passage is positively sealed off when the application of the force is discontinued.
Claims2
A hand-operable system for ejecting a fluid composition into an eye, the system comprising:
- (1) a container having a container opening and containing the fluid composition;
- (2) a double-acting pump mechanism securely disposed over the container opening;
- and (3) a single-piece actuator that is disposed over, and extends radially outward from, and to only one side of, said pump mechanism to form a shoulder that is sized to accommodate a thumb for actuating the pump mechanism by applying a force thereon;
- wherein said pump mechanism comprises a passage for said fluid composition, and said passage is positively sealed off when the application of said force is discontinued;
- wherein said actuator extends longitudinally from the shoulder over a substantial length portion of only one side of the container further than an opposite side of the container;
- and wherein said one side of the container is the same side as the shoulder.
