摘要:
The invention relates to an overpressure valve (10) for the content of a package which is arranged on the internal surface of the packing material (2) of said content of the package. The inventive overpressure valve (10) comprises a base plate (12), a membrane (13) and an assembling element (14). Said overpressure valve (10) has a relatively simple structure and can be produced at a low cost.

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).

The invention concerns a device for the volumetric measurement of the amount of bulk material in a protective atmosphere which ha s several metering chambers (23) on a gradually turned distributing plate (17) which are closed at the bottom by a stationary end plate (18) except for on the pouring station (4). To displace th e air in the metering chambers (23) nozzles are fitted in the end plate (18) through which protective gas is directed from below into the metering chambers (23). A cover plate which rests on the distributing plate (17) outside the filling area prevents air from penetrating the empty metering chambers and a protective gas supply nozzle (42) on the pouring station (4) stops air being sucked into the emptying metering chambers (23).

Between a filler pipe (22) and a moulding pipe (12), a bag forming, filling and sealing machine (10) has at least two seals (28) which separate an annular space (23) formed by the filler pipe (22) and the moulding pipe (12) into an input (31) and an extractor channel (32). The two channels (31, 32) are connected to a suction device (36) with a filter (37) via tubes (34, 35). The design and arrangement of the seals (28) provide a closed circuit for the air or protective gas used for dust removal.
摘要:
The invention relates to a pressure relief valve (10; 50; 60; 65; 66), comprising a base body (11; 67; 68), which is covered by a valve membrane (40; 59). The base body (11; 67; 68), which is located on the inner face (2) of a packaging container, permits the escape of excess pressure from the packaging container into the atmosphere by means of passages (23; 24) and perforations (5) that are configured in the wall (1) of the packaging material. The inventive pressure relief valve (10; 50; 60; 65; 66) thus responds particularly well, i.e. allowing particularly low opening pressures, by means of the special configuration of its base area (15; 55; 67; 68).

摘要:
Disclosed is a vacuum packaging and buffer gas-flushing device for a pouch, which comprises a two-part vacuum chamber (11) in which a parallelepiped gas-flushing pipe (21) is installed above the opening (3) of the pouch-package (1). On the lower portion (22) of said pipe (21), slot-like gas inlets (23) are arranged parallel to each other and at a right angle relative to the pouch (1) opening (3). The inventive device (10) advantageously enables, regardless of the precise position of the pouch (1) opening (3) downstream of the gas-flushing pipe (21), vacuum to be obtained up to a point where only some oxygen residue remains inside the pouch (1).
