    摘要: A bag evacuating and closing apparatus having two opposing jaws which face ends that move toward one another. The jaws encompass a top closure of a bag package to be sealed. The jaws have hollow spaces open toward one another which are surrounded by frames with sealing jaws disposed in the hollow spaces; the hollow spaces form a chamber that receives the top closure of the bag package. A sealing rib protrudes from one face end of the two frames and is interrupted in a middle region of the frame part at which the closure fold protrudes between the jaws. In this region, suction openings are disposed in the frame parts of both jaws; these suction openings pull two walls of the top closure tightly against the frame parts. After the top closure of the bag package has been tightly encompassed, air is extracted from the bag package by a vacuum, and subsequently, the top closure of the package is tightly sealed by the sealing jaws which form a sealing seam to close the upper end of the bag.

    摘要: A tubular bag machine has between a filling tube and a shaping tube at least two sealing elements, which divide an annular space, formed by the filling tube and shaping tube, into a feed channel and a suction-removal channel. The two channels are connected to a suction device with a filter by connecting lines. The design and arrangement of the sealing elements produce a closed circuit for the air or inert gas used for dust removal.

    摘要: The invention relates to a pressure relief valve, comprising a base body, which is covered by a valve membrane. The base body which is located on the inner face of a packaging container, permits the escape of excess pressure from the packaging container into the atmosphere by means of passages and perforations that are configured in the wall of the packaging material. The inventive pressure relief valve thus responds particularly well. i.e. allowing particularly low opening pressures, by means of the special configuration of its base area.

    摘要: The invention relates to a pressure relief valve for a packaging container (3), comprising a base body (4) with at least one through opening (9, 29), a sealing surface (14) and a peripheral region (18), wherein the peripheral region (18) may be sealably connected to an inner surface (3a) of the packaging container (3), the sealing surface (14) having an inwardly tapering form and a flexible membrane (6), in contact with the sealing surface (14) of the base body (4) to generate a sealing effect. The membrane (6) covers the through opening (9), a fluid (5) is arranged between the sealing surface (14) and the membrane (6), wherein a recess (10) is formed in the base body (4) to accommodate thee membrane (6). The recess (10) has a first diameter (D1), between 70 and 80% of a total diameter (D2) of the base body (4).
