摘要：A dispenr for dispensing a substance, such as a pharmaceutical, ophthalmic, dermatological, cosmeceutical, cosmetic or other product, has a body defining a variable‐volume storage chamber for storing the product. A dispensing portion of the dispenr is connected with the body and defines a bore coupled in fluid communication with the storage chamber for receiving substance therefrom, and an outlet aperture coupled in fluid communication with the bore. A one-way valve of the dispenr includes an axially‐extending valve at and an axially-extending flexible valve cover ated on the valve at and defining a normally-clod, axially-extending am therebetween forming a fluid-tight al between the valve cover and valve at. The flexible valve cover is movable relative to the valve at and the am is connectable in fluid communication with the outlet aperture to allow the passage of substance through the am and out of the dispenr. The dispenr further compris an actuator and piston asmbly including a piston receivable within the bore, a manually-engageable actuator connected to the
piston for moving the piston between first and cond positions relative to the bore to dispen substance within the bore through the outlet aperture, and an integral, dome-shaped spring coupled to at least one of the piston and the actuator for biasing the piston in a direction from one of the first and cond positions toward the other.
