ABSTRACT:
A sliding piston opening means enclosed within an elongated container to release the fluid sealed within the elongated container by squeezing the elongated container at or near the sliding piston. After the sliding piston opening means is opened, the fluid sealed within the elongated container is released for application. Before the content of the container is depleted, the sliding piston opening means is used to re-close the opening thereby re-sealing the fluid remaining within the container.
