Abstract: An improvement of fire-resistant laminated glass is provided, which serves to retard spreading fire and high heat in conflagration, and normally acts as crashworthy glass, wherein plural potash glass sheets are bound as a whole by means of PVB (polyvinyl butyral) and form the laminated glass, in which the PVB reinforces the potash glass by multiplying a crashworthiness thereof and the potash glass, as a product of processing soda-lime glass with the known chemical enhanced treatment, is high-temperature endurable.

Abstract: A sealing cap fastened to a vacuum seal container and controlled to extract air out of vacuum seal container, the sealing cap including a cap body unit fastened to the vacuum seal container, and an extracting unit mounted in the cap body and controlled to extract air out of the vacuum seal container by reciprocating a control cap of the extracting unit with the hand, the air passage being automatically sealed by a flap, which is forced into the close position by atmospheric pressure, the vacuum status of the vacuum seal container being released when a control cap of the air extracting unit is turned in one direction and pressed down, the cap body having a bottom side covered with a rubber disk which fits different spout sizes and shapes, the rubber disk being secured to the cap body by a T-cap and a sponge between the T-cap and the rubber disk, the rubber disk having a convex flange of V-shaped cross section around the periphery, which prohibits the rubber disk from being forced to curve inwards and to escape

Abstract: A sealing plug cap includes a plug cap body fastened to the mouth of a sealing container to seal the passage of the mouth by a deformatable peripheral flap thereof, an air buffer device fastened to the bottom end of the plug cap body inside the sealing container to buffer the speed of air passing through a center air hole on the plug cap body, a socket mounted inside the plug cap body, and a sealing and relief control unit mounted in the socket, the sealing and relief control unit being forced by atmospheric pressure to close the air hole on the plug cap body when a suction pump is used to draw air out of the sealing container, the sealing and relief control unit being forced to open the air hole on the plug cap body when depressed.

Abstract: A sealed container and suction pump unit including a sealed container, and a suction pump adapted for drawing air out of the sealed container, the suction pump having a vacuum mount adapted for securing to the container body of the sealed container, and a bottom coupling groove adapted for coupling to the container cover of the container body of the sealed container, the container cover of the sealed container having a center air hole through which air can be drawn out of the container body by the suction pump, an upward coupling flange raised around the center air hole and adapted for engaging the bottom coupling groove, an air filter element mounted in the center air hole to remove solid particles from air passing through, a metal pressure plate supported on a seal ring inside the center air hole and attracted by a magnet to seal the air passage, and a press member mounted in the center air hole and controlled to tilt the metal pressure plate in opening the air passage.
