Abstract: The device for discharging air and/or tire sealant (3) from a container (2) useful in automotive industry, comprises a fastening element (1), a pressure source connectable at the fastening element, a withdrawal opening (12) for discharging air and/or tire sealant from the container, and an inlet closure (9) formed as an inlet valve, a non-return valve, a plug, a closure plug and/or a flap for connecting the pressure source. A closure of the withdrawal opening is released in the area of the fastening element or over a separate withdrawal mechanism. The device for discharging air and/or tire sealant (3) from a container (2) useful in automotive industry, comprises a fastening element (1), a pressure source connectable at the fastening element, a withdrawal opening (12) for discharging air and/or tire sealant from the container, and an inlet closure (9) formed as an inlet valve, a non-return valve, a plug, a closure plug and/or a flap for connecting the pressure source. A closure of the withdrawal opening is released in the area of the fastening element or over a separate withdrawal mechanism. The container is connectable with the fastening element. The withdrawal opening is released into the tire during the production of a positive pressure in the container. The inlet closure of an inlet (7) is released to an inner chamber of the container during the production of the positive pressure. The inlet closure opens during reaching the positive pressure with the connection of a compressor and/or gas bottle of the inlet closure. The container is subjected with the tire sealant with pressure. The inlet closure is formed as non-return valve or as closure plug, which releases a pressure of 2-5 bar. The withdrawal opening is locked by the closure, which releases the withdrawal opening during the transferring of the certain positive pressure in the container. The withdrawal mechanism is arranged to the fastening element distanced directly or over an uptake, and is formed from a base body, in which the closure is intended for releasing inlet opening and/or the inlet. The closure releases the inlet opening of the base body during the existence of the positive pressure to bring the tire sealants directly over an outlet or indirectly over the uptake to a connection tube for connecting to a valve of the tire, and is used as plug in the withdrawal opening of the base body. The withdrawal opening for the tire sealant releases over the outlet and the connection tube into the tire during the positive pressure. The closure is intended for locking the withdrawal opening in the outlet. The container is positioned over a head for bringing the tire sealant from the container. The withdrawal mechanism connects over the uptake with the integrated closure spaced to the fastening element and is arranged nearly to a base of the container. A specific weight of the withdrawal mechanism is higher than a specific weight of the tire sealant. A specific weight of the closure is lighter than a specific weight of the tire sealant. The base body has an enlarged inner chamber and a shut-off element to ensure a flow of the tire sealant by the uptake for the admission of the closure after pushing. The closure is formed as flap or as elastically formable element, which releases the withdrawal opening for bringing the tire sealant over the outlet from the fastening element. The fastening element over a connection tube is directly connectable to a valve of a vehicle tire with or without inserted valve for bringing the tire sealant into the tire. The connection tube of small length is connectable to the fastening element. The container at the valve of the vehicle tire is attachable over the connection tube. The connection tube has a length of 3 cm. The container is detachably fixed by the connection tube to the valve of the vehicle tire. The bent-shaped connection tube is rotatably and/or pivotably placed around its center axis in the area of the closure. The bent connection tube is laterally placed at the container adjacent or in a separate absorption trough in bent condition. The container is set with a compressor under pressure, and is formed as pressure resistant container, at which the outlet with the connection tube and the inlet connect directly over the fastening element or indirectly over a container wall. The container is formed as flexible bag, which has a pressure-resistant of 10 bar. The flexible bag is formed from the pressure resistant plastic or composite materials.
