Dry flowable material dispensing and contents preservation and sterilization apparatus |
摘要 |
A pressurizable container has a removable cover. The removable cover has locking elements to maintain the cover sealed to the container when the container is pressurized. The locking device is a piston received in a cylinder, and the cylinder communicates with the interior of the container. When the container is pressurized, the pressure fluid forces the piston and its associated locking bolt into a position such that the bolt passes through a wall of the container and a wall of the removable cover, locking the cover to the container. It is also possible to draw a vacuum on the container when the container is used as a sterilizing device.
