ABSTRACT:
A one-way valve for dispensing a fluid material from a container includes an axially extending valve body and an elastomeric sleeve stretched over the valve body in tightly fitting contact with it. A ring shaped enlargement is formed monolithically on each end of the sleeve and fits in sealed contact with reduced diameter portions at the opposite ends of the valve body. The sleeve can be assembled on the valve body in a variety of ways including mechanically expanding the sleeve and placing it on the valve body. The enlargements at the ends of the valve body have a thickness dimension in the radial direction in the range of 2 to 4 times the thickness of the sleeve between the enlargements.
