Abstract: A combustion device has a controllable venting mechanism, within a piston/plunger or a chamber/housing, to allow the flow of air out of the chamber to enable the piston/plunger to be freely inserted for the purpose of storage or to maintain the air within the chamber to enable the piston/plunger to create a pressure necessary for combustion.

Abstract: A sterilizable system and method for sterilizing containers in an autoclave. The system includes a container, closure bag, and fastener. The closure is placed in the interior of the bag, and the opening of the container is put into the interior of the bag through the bag's opening. The closure and container are kept in non-sealing relationship, and the sterilizable system is completed by fastening the opening of the bag around the container with the fastener. Once the system is sterilized, the user seals the container and closure by grasping the bag and manipulating the closure into sealing relationship with the container. The user then removes the fastener and bag, leaving a sterilized container.
