Definitions

  • the invention relates to a packaging container for receiving a flowable product, which consists of a flexible sack stored in a rigid envelope with a closable outlet bung and the opening of the envelope associated therewith, an abutment and the abutment bung arranged on the opening before use within the envelope a handle attachment are arranged.
  • the invention further relates to a method for producing the packaging container.
  • An essential feature of packaging of this type is the sack or bag for holding liquid, which is arranged within a stable packaging container, cardboard boxes or the like, and has an outlet bung, in particular with a built-in valve.
  • relatively large amounts of liquid for example 10 to 30 liters each, are brought onto the market in such so-called bag-in-box containers.
  • Products with water-thin to paste-like viscosity can be stored, transported or made available. In use, the respective product is drained through the outlet bung or sucked off, for example.
  • bag-in-box packaging An important aspect for the use of bag-in-box packaging is that the customer does not have to accept the weight of glass bottles when buying a cardboard box with a liquid bag inside. Furthermore, there is no bulky empties after the packaging has been emptied, since such packaging after use are collapsible or compressible to a small volume.
  • the application extends to a wide variety of different types of flowable substances, such as food, wine or cleaning agents.
  • such packaging can be designed and operated, for example, so that no air penetrates into the bag during emptying, so that the flexible bag shrinks in accordance with the amount of liquid removed from it within the envelope and also over a longer period of time Liquid can be removed at any time without the risk that the liquid loses its quality due to exposure to air.
  • provision can also be made, inter alia, to apply a pressure above the ambient pressure to the bag during the removal of liquid, for example with sterile gas, in order to rule out premature contact of the packaging contents with non-sterile gas.
  • the outlet bung When storing and transporting the packaging, the outlet bung is preferably sunk inside the wrapper, possibly a closure of the bung can partially or completely protrude over the outer wrapping surface.
  • the sheet In use, the sheet is pulled out of the covering, for example made of corrugated cardboard, and fixed in the wall of the covering so that it cannot slip back into the covering automatically and, in particular, cannot rotate about the axis of the sheet pipe.
  • the invention has for its object to improve the aforementioned packaging container so that the outlet bung without tedious manipulations and without major construction and manufacturing effort simply by pulling it out of its associated opening of the wrapping to be automatically locked in the pulled-out position, and the packaging container is technically easy to manufacture overall.
  • this object is achieved according to the invention in that the abutment is a spreading collar which unfolds when pulled out of the opening and lies on the outer surface of the casing and consists of individual spreading fingers, above which a circumferential stop and below which is arranged on the circumference of the outlet bung against rotation from approximately axially and radially aligned webs, and that the handle attachment is designed as a pull loop.
  • the expanding collar which unfolds when the outlet bung is pulled out of the covering prevents the bung from sliding back into the covering.
  • the spread collar itself can be designed in a variety of ways. It is easy to manufacture if it consists of a plurality of fingers which unfold after being pulled out of the opening. To make it easier to pull it out, the invention further provides that the outer edge of the expansion collar is bevelled on the outside thereof so that it slopes away radially.
  • the circumferential stop arranged above the expansion collar prevents the outlet bung from being pulled back or pushed back by overturning the expansion collar.
  • an expanding abutment is found on the circumferential stop, which prevents the bung from being pushed back into the casing without being destroyed.
  • a pull loop is formed on the outlet bung.
  • the pulling loop is fastened to a closure of the outlet bung.
  • the invention provides that the stop is designed as a retaining ring and is arranged on the bung at a distance from the spreading fingers, forming a groove.
  • the outlet bung is especially designed for fully automatic filling and assembly on commercially available machines, in which case conventional claws from filling machines move into the groove and the vertical contact pressures of the mandrel that occur during the filling process can be transferred to the holding claws and intercepted during the filling process.
  • the anti-rotation device for the fully automatic filling of the packaging container according to the invention, it is expedient for the anti-rotation device to consist of individual webs formed on the circumference of the lower bung area, ending in a tip, and two diametrically opposite web pairs, the common side surface of the respective web pairs each tangentially is molded onto the outer wall of the lower bung area and spreading fingers projecting above the web pairs, forming a groove, are arranged above the side surfaces of the web pairs.
  • This configuration makes it possible to feed the still empty, flexible bag or inliner to the filling station in a pre-oriented and orderly manner by means of a guide rail which is customary on such fully automatic filling machines and which engages in the above groove.
  • a particularly long and therefore flexible embodiment of the spreading fingers which makes it easier to pull the outlet bung out of the envelope without allowing it to be pushed back into the envelope, is achieved in that the side edges of the spreading fingers are aligned parallel to the side surfaces of the web pairs and to the bung axis. as the invention further provides.
  • the invention further provides that the spreading fingers are rounded at their edges.
  • the invention provides, in an embodiment to facilitate the penetration of the anti-rotation device into the casing, that the webs have an upper bevel.
  • the invention further provides that the outlet bung between the closure and the expansion collar has a waist that is sunk into the casing before use. This waist in the manner of a neck should be at least so long that the outlet end of the bung is at a sufficient distance from the adjacent casing wall for use.
  • the outlet bung is made in three parts from a lower bung, an adapter part with a threaded area and a supporting edge and a closure with a pull loop, as is also provided by the invention.
  • the object according to the invention is achieved in that a hole is punched in a first film web to form a flexible sack and a welding ring of the outlet bung is welded to the film region adjacent to the hole, and then a second film web is welded to the first film web optionally welded to the flexible sack after being cut to length and packaged in an envelope.
  • the wrapping 1 consists of a flexible bag 2, a so-called inliner, stored in a rigid wrapping 1, with a closable outlet bung 3 and an associated opening 4 of the wrapping 1.
  • the wrapping 1 can be a rectangular box, in particular with Corrugated walls, act.
  • the sack 2 consists of a material adapted to the respective application, in particular the flowable substance to be stored. A flexible, possibly multilayer film.
  • the outlet bung can be formed in one piece from plastic and welded to the bag 2.
  • the bung which is denoted overall by 3 has a ring 5 to be welded to the sack 2 on one inner end 6 of an approximately tubular body, the other outer end 7 of which is to be closed with a cover 8 .
  • the cover 8 can, for example, be clamped or screwed onto the outer end.
  • it has an integrally formed pulling loop 9, which is used to pull the outlet bung 3 out of its position within the casing 3 through its opening 4. Pulling out is made easier if the bung 3 below the cover 8 is equipped with a waist 10 designed in the manner of a neck.
  • the waist 10 merges at its lower end facing away from the outer end 7 into a circumferential stop 11, against which spread fingers 12 unfold when the bung 3 is pulled out of the opening 4.
  • the spreading fingers 12 can also be spread apart in the position within the casing 1. They then fold when pulling the bung 3 through the opening 4 and jump outside the opening 4 relieved back to the original position.
  • the annular stop 11 above the spreading fingers 12 prevents the spreading fingers 12 from folding back even when pressure is exerted on the bung 3 and thus prevents the bung 3 from being pushed back into the interior of the casing 1.
  • FIGS. 1 and 2 show two slightly modified embodiments of an outlet bung 3 and 3a.
  • the reference numerals from FIGS. 1 and 2 have been retained for parts which are identical to those from FIGS. 1 and 2.
  • FIGS. 3 to 6 have configurations which improve the outlet bung in such a way that fully automatic filling and packaging of the packaging is possible on commercially available machines and, moreover, aseptic filling can also be implemented. Furthermore, execution details are shown which bring about an improvement in the outlet bung in such a way that an injury to the inner bag during transport, storage or fall is avoided. In addition, process-related savings can be realized.
  • FIGS. 3 to 5 show an outlet bung 3 which has a stable holding ring 16 above the spreading fingers 12. Between the spreading fingers 12 and the retaining ring 16, this results in a circumferential groove 17, which is used for the exact fixing of the outlet bung 3 in the filling position of a filling machine and into which, for this purpose, two-sided holding claws can be inserted on such machines.
  • the stable retaining ring 16 By means of the stable retaining ring 16, the vertical contact pressures of the filling mandrel which occur during the filling process of the packaging container are transferred to the claws of the filling machine and intercepted.
  • the holding ring 16 takes over the function of the stop 11 according to the exemplary embodiment in FIG. 2.
  • the diameter of the holding ring 16 is the same or slightly smaller than the diameter D of the lower bung area 18 in order to pull the bung 3 out of the opening 4 in the casing 1 not to interfere with the application. It goes without saying that the diameter of the opening 4 in all embodiments of the outlet bung is only slightly larger than the diameter of the lower bung area 18 and apart from the spreading fingers 12, 21, the webs 15, 19 and the welding ring 5 no part of it Outlet bung is arranged, which projects beyond the diameter D of the lower bung area. On the circumference of the lower bung area, individual webs 15 and two diametrically opposed web pairs 19 are formed in a tip.
  • the respective web pairs 19 have a common side surface 20, which is in each case formed tangentially on the outer wall of the lower bung area 18.
  • the respective side surfaces are formed parallel to one another and parallel to the bung axis 27.
  • spreading fingers 21 are arranged on the outer circumference of the outlet bung 19 projecting beyond the side surfaces 20 of the web pairs 19.
  • grooves 22 are formed in each case by the surface of the welding ring 5, the respective side surfaces 20 of the web pairs 19 and the respective underside of the spreading fingers 21, which are used for drawing in and pre-orienting an empty inliner via a guide rail into a filling machine.
  • the tapering ends or edges of the webs 15 and the web pairs 19 cut into the casing 1 when the outlet bung 3 is pulled out and lock the outlet bung 3 against twisting.
  • the webs 15 and 19 have upper bevels 23 and 24.
  • the outer edges or corners of the spreading fingers 12, 21 are rounded off with radii 25, 26.
  • the side edges of the smaller spreading fingers 12 run parallel to the outlet bung axis 27 and to the surfaces 20 of the web pairs 19.
  • an outlet bung 3a is shown, which has all the features of the bung 3 described above, but which is formed in three parts and consists of a lower bung 33, an adapter part 28 with a threaded region 29 and supporting edge 30 and a closure 8 with a pull loop 9.
  • the adapter part 28 is bumped into the lower bung 33.
  • the snap bead and the snap groove in the area 34 of the adapter part 28 and the lower bung 33 are designed such that they engage in a sealing and non-rotatable manner and, with the cooperation of the supporting edge 30, resist the vertical force transmission of a filler neck of a filling machine during the filling process.
  • the threaded part 29 with unscrewed screw closure 8 is dimensioned such that the outside diameter of the screw connection is not larger than the outside diameter of the retaining ring 16.
  • the adapter part 28, pre-assembled with a closure 8 or removal aid is brought under aseptic conditions with the outlet bung 3a, which is already welded to the empty inner bag, into a first, provisional closure position in which only the lower edge 31 of the adapter part 28 is in the engages upper ring 32 of the bung 3a. That means that the inliner with bung and the clamped adapter / closure assembly is drawn into a filling machine, where the adapter / closure combination is then removed by a gripper in the filling position under the influence of protective gas, and the inliner is filled and then finally closed in the same position by being punched in.
  • the inliner or the flexible sack is welded together from at least two flat film webs.
  • film webs preferably wound on rolls, are continuously unwound from the rolls and fed to a welding machine as superimposed webs.
  • a hole is first punched into the surface of the upper sheet, into which the outlet bung is then inserted and welded to the sheet of film on the welding ring.
  • a manufacturing process for the packaging container according to the invention proceeds as follows. First, a first film web is drawn into the processing machine.
  • the hole for the outlet bung is punched into this first film web and then, after inserting the bung into this pre-punched hole, the welding ring of the bung is welded to the region of the film web adjacent to the hole. Then a second film web is guided under the first film web, whereupon the two webs are connected to one another by lateral longitudinal welding to form a tube. The welded-in bung is then closed, for example by bumping in a stopper or the like, before the finished inliner or sack is produced by transverse welding of a top and bottom seam to the tube.
  • a tear-off perforation is provided between the top seam of the one and the bottom seam of the next inliner before the flat-lying and contiguous inliners are packaged in an outer packaging.
  • the inliners are later removed from the outer packaging, separated from one another and fed to the filling machines for filling with product.
  • the filled inliner is then packaged in the wrapper, for example a corrugated cardboard box.
