A system for releasing a contained volume of gas. The system has a base with a pressure-release vent positioned within a flex region and a seal to disengagably seal the pressure-release vent. The seal has a gas vent path that extends from the pressure-release vent. The contained volume of gas passes through the gas vent path to apply force against the flex region and disengage the seal from the pressure-release vent, allowing the gas to exit through the pressure-release vent.

The fastener container in the present invention includes a lid and a receptacle base as main components combined together. Said lid has a first section and a second section which are connected by a hinge. This invention used the first prominent portion with flexible cushioning effect and the pressing member of the first prominent portion of the first section, and the blocking member and the third recess of the second prominent portion of the second section to reduce the wear and tear between the pressing member and the blocking member, it also can prevent the pressing member from squeezing the blocking member for a long time to result in a problem that the pressing member and the blocking member are deformed and the first section can not be held in the open position, so that the service life of the lid can be extended and the user can easily open or close the first section of the lid to take or place screws or other items.
