Abstract: A plant for manufacturing and packaging tubes feeds the tubes via a conveyor belt to a packaging station, where they are packaged to form larger units. The foil strip is a dual or multiple-strip, cut by at least one partitioning blade into individual webs respectively welded in parallel planes to form endless tubes and cut by transverse cutters. The tubular bodies are assembled into a larger transfer group and jointly transferred to a turn table including a corresponding number of mandrels. The turn table conveys them jointly and stepwise to stations for fitting the shoulder portion with a threaded neck and the closure cap. The finished tubes are deposited on a discharge belt and fed to control regions for checking. Flawless tubes are received by the discharge belt and fed continuously to a tray.

Abstract: The invention relates to a two-chamber container, in particular as a non-resealable disposable packaging, wherein the two-chamber container has an inner chamber (1) and an outer chamber (2) surrounding the inner chamber (1), and a cap (3) produced by compression of plastics material, with which the upper edges of the wall of the inner chamber (1) and those of the outer chamber (2) are rigidly connected, the cap (3) having two separate channels (71, 72), and the inner chamber (1) being arranged asymmetrically inside the outer chamber (2) in such a way that a portion of its wall is secured to the cap (3) in the region between the channels (71, 72) in such a way that one channel (71, 72) is connected to one of the chambers (1 or 2) in each case.

Abstract: The invention relates to a method for producing tubular containers with an open filling opening and with an end that is provided with a seal. The inventive method comprises the following steps: separately producing a preform with a neck with definitive dimensions and a tubular body with smaller dimensions than the definitive form, the tubular body containing the open filling opening; fixing the preform that is produced to a drawing head by its neck and subjecting it to at least one partial heating process; introducing the heated preform that is attached to the drawing head into the inside of a multi-part closed blow mold in such a way that the open filling opening is air-tightly held at the lower end of the blow mold; fitting a blow nozzle to the filling opening of the preform.

Abstract: A method and a device for the continuous production of tubular bodies with an internal longitudinal separating wall for the production of tubes having two chambers which are separated from each other. An endless extruded tube having an internal longitudinal separating wall is produced and individual tubular bodies of a defined length are cut off by means of a cutting device and subjected to further processing. The tubular body is made from a film having a central, semicircular part and two angled lateral wings. The semicircular part is covered by a second film serving as separating wall. A transverse cutter having two rotating blades is used as cutting device.

Abstract: The invention relates to a method for producing a two-chamber tube with a dividing wall (9) that extends into the tube head.

Abstract: A process produces a tubular body with at least one dividing wall extending across its length and forming longitudinal chambers disposed next to each other. A foil strip is used whereby a dividing-wall strip or a section of dividing-wall strip is cut to length and is fastened at its lateral outer edges on the foil strip or section of the foil strip, with parallel alignment with the foil strip or section of foil strip. The lateral edges of the foil strip or section of foil strip are then joined with each other thereby either directly forming a tubular body or forming an endless tube, from which tubular bodies are then cut to length. The tube is then solidly joined with a tube head having a dividing bridge conforming to the arrangement of the dividing wall in the tubular body. The tube head has a dispensing aperture closable by a closure.

Abstract: The invention relates to a method for the production of tubes from a prefinished pipe element, by pressing of heated plastic blanks to form a multi-layer tube head, with simultaneous bonding of the tube head to the pipe element. According to the invention, each layer of the multi-layer tube head is produced individually, by pressing of a newly introduced plastic blank in each case, where the next blank for the subsequent layer is not introduced and pressed until after the layer previously produced is stable in shape. The invention also relates to a tube made of a pipe element (1) having at least one plastic layer, and a multi-layer tube head (2) molded on by pressing heated plastic blanks, with a neck part (8) opening out centrally in a dispensing opening (9) with an outside thread (11) to screw on a closure cap, where according to the invention, each layer (3, 6, 5) of the multi-layer tube head (2) is pressed in individually, layer by layer, onto the upper end of the pipe element (1).

Abstract: The invention relates to an apparatus for the production of tubes from prefinished pipe elements, by pressing cf a tube head from a heated blank (24) of a plastic, with simultaneous bonding of the latter to the tube pipe (13), with an indexed transport means which stops at several work stations (II-VII) arranged at equal distances from one another, with mandrels (7) that travel along to hold the pipe elements (13) and dies (5) arranged coaxial to the mandrels (7), which also travel along, and have central hole punches (21"), if necesary, where the mandrels (7) can be axially moved and are arranged to work together with a press (8) in such a way that they can be inserted into the dies (5) to press the tube head, as well as with a loading and unloading station (I, VIII) and with an extruder (12) and a metering device (11).

Abstract: A packaging tube is provided which is substantially gas-tight and has low absorptivity, consisting of a tube of multilayer composite foil with a metallic barrier layer, a prefabricated plastic head piece having a discharge opening and an external thread, and a connecting body which consists of a composite foil containing a metal layer and at least one thermoplastic material layer. The head piece is placed on the connecting body and is welded thereto by means of the plastic layer. The circumferential rim of the tube overlaps the outer rim of the connecting body extending over or under the same, and its plastic layers are softened by the inductive generation of heat in the metal of the composite foil and are welded together while pressure is applied. The head piece has the shape of a cylinder or a truncated cone and is joined at its base area completely to the connecting body.

Abstract: A process for making head pieces for containers with a membrane of laminate having a metallic barrier layer, is designed to make one-piece head pieces, of a thermoplastic material with a mouthpiece neck, a cone-like breast part next to it, a ring-shoulder next to the breast part, a ready-made round plate and a membrane of a laminate with a metallic barrier layer. From a tape of laminate with a metallic barrier layer, using a deep drawing operation, the round plate is produced in a form representative of the outline of the head piece to be produced, is stamped out and is then run down into a mold. At the same time as the lowering the membrane is stamped out of the center part and is kept in position. After this thermoplastic material is placed in the mold and then the membrane is lowered into its last position in the mold and at the same time as the lowering of the membrane pressing of the thermoplastic material in the mold takes place.
