An easily opened elongated container filled with various liquids is disclosed. The container has a first open end and a second open end. A sealing device closes the first open end of the elongated container. A plunger rod that extends into the elongated tubular container closes the second open end. Pushing the plunger rod produces a hydraulic pressure of the liquid in the elongated tubular container so that the hydraulic pressure opens the sealing device. Finally, an opening device opens the second open end of the elongated tubular container so that liquid can flow out of the first open end, which has been opened by the hydraulic pressure. |
