摘要： The invention relates to an outlet connector piece (1) having a protruding flange (3) for non-detachably securing said outlet connector piece to a tubular bag (12). The flange (3) has a contact surface (4) which is designed for a welding or adhesive connection to the tubular bag and surrounds an outlet connector piece passage along a circumference (6). The contact surface (4) is rectangular or square, and the flange (3) has, extending parallel in a direction of extension, a film hinge (7) on each side at a distance from said outlet connector piece passage.

摘要： The invention relates to a method for dispensing viscous or pasty ingredients (12), which are packaged in an aseptic manner, from a tubular bag (1), which is closed prior to the first use, by means of a disposable pump (4) attached to the bag. The disposable pump (4) has an inlet (5) with a cutting element (6), and a nozzle (2) with a flange (3) is welded onto the tubular bag (1). The disposable pump (4) is rotated relative to the nozzle (2), and the tubular bag (1) is thereby cut open. A valve (9) is arranged in the region of the outlet opening of an outlet tube (8) of the pump, and the disposable pump (4) is operated after the initial opening process until a freely selectable volume has exited the closing valve. The disposable pump (4) is then operated in the opposite rotational direction in order to suction ingredients (12) present on or in the region of the valve (9) back into the outlet tube (8). In the process, the valve (9) reaches or remains in the closed valve state. A valve (9) is proposed for carrying out the method. The valve is arranged in the outlet tube (8) and comprises a membrane (93, 191) which is sealingly mounted in a sliding manner or can be inverted. Using the method, the ingredients (12) can be dispensed in a metered manner from a tubular bag (1), in which the ingredients are aseptically packaged, into virtually aseptic containers until the ingredients are practically completely used.

摘要： A dispenser cartridge (10) which comprises a first and a second cartridge shell (11, 12). The two cartridge shells (11, 12) are connected via a hinge (14). The two cartridge shells delimit a receiving space (25) for tubular bags. Each cartridge shell has a cooling trough (30) which, apart from an inlet port (26) and ventilation openings (33), is closed to the receiving space (25) for the tubular bags by a thermally conductive plate (18). The receiving volume of the cooling trough (30) is kept as low as possible. The depth of the cooling trough (30) corresponds to a maximum of twice the thickness of the thermally conductive plate (18). The greater the volume of the receiving space (25) for corresponding tubular bags, the greater the thickness of the thermally conductive plate (18).

摘要： The invention relates to a method for producing tubular bags made from plastic film or from composite film having a plastic layer on the bag content side, having a self-cutting plastic closure attached to the tubular bag, consisting of a spout part having a fastening flange, a cutting body, which is movably guided in the spout part, and a screw cover having means for activating the cutting body. The film material (5) is supplied from a supply roll to a bag manufacturing machine and the plastic closure is sealed onto the film material in a spout region of a tubular bag. According to the invention, the film material (5) is thinned on the inside of the bag in a ring-shaped region, which is intended for cutting by the cutting body, by means of a thermal embossing process. The plastic closure is then positioned and sealed onto the film material such that the cutting organ embedded in the spout part can become effective in the thinned, ring-shaped region upon use thereof.

摘要： A disposable metering pump is made of plastic for products having solid fractions. The disposable metering pump has two rotors (10) which are coupled to each other by means of gears (11), can be driven in opposite directions, and are supported in a pump housing (5). Each rotor (10) has a rotor shaft, the rotor shaft ends (15) of which are supported in the walls of the pump housing (5). Each rotor (10) has two rotor blade walls (13), which are arranged diametrically opposite on the rotor shaft. One partially cylindrical rotor blade shoe (14) is formed at each of the peripheral ends of the rotor blade walls. The rotor blade shoes (14) lie against the cylindrical inner wall regions of the pump housing (5) in a sliding and sealing manner.
