Definitions

  • the invention relates to a packaging container for receiving a flowable product, which is formed by a flexible sack stored in a rigid envelope with a closable outlet bung and an opening associated therewith, the outlet bung being fixable at the edge of the opening with an abutment integrally formed on the bung neck and with a laterally directed one Product outlet pipe is provided, which branches off radially laterally from an axially directed upper part of the outlet bung, the outlet cross section of which can be closed and released by means of a cylindrical tube extending into the upper part with a corresponding opening of a closure cap which can be rotated with respect to the outlet bung, whereby between the upper part and the Bungneck a radially outwardly extending fixing flange is formed.
  • the closable container outlet is preferably made in three parts.
  • the closable container outlet consists of a flexible sack, e.g. B. by welding fixed abutments, a bung into this abutment and a bung Sealing cap.
  • the outlet bung is provided with a laterally directed product outlet tube which branches radially laterally from an axially directed cylindrical inner tube of the outlet bung, the outlet cross section of which can be closed and released by means of a cylindrical tube extending into the inner tube with a corresponding opening of a closure cap which can be rotated relative to the outlet bung .
  • the cross-section of the cylindrical inner tube of the outlet bung is considerably smaller than the cross-section of the abutment, which can lead to complications when emptying if higher-viscosity media are used.
  • this problem does not arise during filling, since the outlet bung is then separated from the abutment and is only injected into the abutment after filling.
  • this closure is made in two parts, i.e. the abutment and the outlet bung consist of only one part onto which the closure cap can be pushed, only the small cross-section of the cylindrical inner tube of the outlet bung is available for filling and emptying, which in particular slows down the filling process, which leads to higher filling times and thus costs.
  • This closure could then be enlarged overall in order to obtain a larger cross-section, but this would lead to a higher material expenditure and thus higher manufacturing costs.
  • the packaging would have to container for receiving this larger closure can be designed accordingly larger.
  • the object of the invention is to provide a solution which makes it possible to form the closure of a container of the type in question in such a way that the passage cross section of the closure is as large as possible while maintaining a reliable seal and as little material consumption as possible, the closure also being to be space-saving.
  • this object is achieved according to the invention in that the tubular upper part with a lateral product outlet tube is formed on the outer edge of the fixing flange and the bung neck is extended beyond the fixing flange by means of an inner tube piece into the lower end of the upper part below the product outlet tube, such that an annular gap is formed between the upper part and the inner tube piece for sealingly receiving the inner tube of the closure cap.
  • the full opening cross-section of the container opening in the outlet bung is available in the packaging container according to the invention with a bung-cock closure for filling the container, since all guide, sealing and locking elements outside the loading container opening are formed. Even after the sealing cap has been dented, the passage cross-section with respect to the container opening is not reduced as far as directly to the product outlet pipe, so that this closure can also be used without problems for highly viscous media.
  • the seal is still improved, since the opening of the closure cap and the outlet cross section of the product outlet tube are further apart in the closed position.
  • the closure saves space and material, since the design is simpler than the known closure, ie, for example, it does not require a cylindrical inner tube in the outlet bung.
  • the invention provides that a circumferential snap bead is formed in the area of the annular gap on the upper part of the outlet bung and at least one circumferential snap groove is formed on the lower end of the cylindrical tube of the closure cap.
  • closure cap can first be applied to the outlet bung in a so-called pre-bouncing position before the container is filled, in that the closure cap is only pushed in to the extent that the snap bead of the outlet bung snaps into the lower snap groove of the closure cap.
  • the closure cap is then pulled off again and, after filling, completely pushed into the outlet bung, i.e. by snapping the snap bead into the second snap groove.
  • a particularly good seal between the outlet bung and the closure cap is achieved if the inner tube piece of the outlet bung widens conically in the area of the annular gap towards the fixing flange and the inside of the lower end of the cylindrical tube of the closure cap is correspondingly beveled conically. After the closure cap has been completely pushed in, these conical sealing surfaces lie against one another in a sealing manner.
  • a further advantageous embodiment of the invention provides that the closure cap with a cylindrical outer wall surrounds the upper end of the upper part of the outlet bung to form a second annular gap.
  • This design of the cap is a second Guide created between the cap and the outlet bung, whereby the twisting of the cap to open or close is facilitated.
  • a circumferential snap bead is formed on the cylindrical tube of the closure cap in the region of the second annular gap and at least one inner circumferential snap groove is formed on the upper end of the upper part of the outlet bung, two inner circumferential snap grooves also being formed on the upper end of the upper part of the outlet bung could be.
  • This additional locking at the upper end of the outlet bung improves the guidance between the two elements, with the provision of two snap grooves also providing an additional locking in the pre-bump position.
  • outlet cross section of the product outlet tube and the opening of the cylindrical tube of the closure cap are oval, the outlet cross section or the opening being formed with an edge bead on the side facing each other.
  • This embodiment with an enlarged outlet cross section is provided in particular when higher-viscosity media are to be used.
  • the additional bead in the connection area ensures a secure seal between the outlet bung and the Cap so that no product can escape undesirably.
  • a discharge bung In a multilayer carton 1 of a packaging container, which is only hinted at in Fig. 1, a discharge bung, generally designated 2, is provided, on the bung neck 3 of which a flange 4 is integrally formed, the flange 4 being designed as a welding flange, i.e. A plastic bag 5 arranged in the box 1 is welded there in a liquid-tight manner, the opening of the welding flange 4 being located directly above an opening 6 of the plastic bag 5.
  • the outlet bung 2 has a circumferential fixing flange or edge 7, on the outer edge of which a tubular upper part 8 is formed, the inside diameter of which is larger than the inside diameter of the bung neck 3.
  • a radially laterally directed product outlet pipe 9 with outlet cross section 10 is provided on the upper part 8.
  • a shoulder 12 is formed, which extends over a little more than a quarter circle and is arranged opposite the product outlet pipe 9 in a diagonally opposite position.
  • the bung neck 3 is extended beyond the fixing flange 7 into the interior of the cylindrical upper part 8 below the product outlet pipe 9 into an inner tube piece 13, a circumferential annular gap 14 being formed between the upper part 8 and the inner tube piece 13.
  • a closure cap generally designated 15 for the outlet bung 2 is shown.
  • the closure cap 15 has a cylindrical tube 16 with a lateral opening 17, the opening cross section of which corresponds to the outlet cross section 10 of the product outlet tube 9 at the outlet bung 2.
  • the cylindrical tube 16 is closed at the top by means of a head plate 18, to which a cylindrical outer wall 19 protruding beyond the outer diameter of the cylindrical tube 16 is formed, through which a second annular gap 20 between the cylindrical outer wall 19 and the cylindrical tube 16 for attachment the tubular upper part 8 of the outlet bung 2 is formed.
  • a protruding cam 21 is provided within the second annular gap 20, offset by approximately 90 ° to the position of the opening 17, the height of which cam is somewhat lower than the shoulder 12 at the outlet bung 2.
  • a web 22 is formed parallel to the axis of the opening 17.
  • Fig. 5 shows a so-called preliminary position of the closure cap 15 with respect to the outlet bung 2. This means that during manufacture the welding flange 4 of the outlet bung is first welded to the plastic bag 5 and then the closure cap 15 is pressed onto the outlet bung 2 in such a way that between a certain minimum distance of, for example, 3 mm remains at the lower end of the cylindrical outer wall 19 of the closure cap 15 and the upper edge of the product outlet pipe 9 of the outlet bung 2.
  • a circumferential snap bead 23 is formed in the area of the annular gap 14 on the upper part 8 of the outlet bung 2, and two circumferential snap grooves 24, 25 are provided one above the other at the lower end of the cylindrical tube 16 of the closure cap 15.
  • a circumferential snap bead 26 is formed on the cylindrical tube 16 of the closure cap 2 in the region of the second annular gap 20, which can snap into two circumferential snap grooves 27, 28 on the upper end of the upper part 8 of the outlet bung 2.
  • the lower snap groove 24 engages on the cylindrical tube 16 of the closure cap 15 over the circumferential snap bead 23 of the outlet bung 2, while at the same time the upper snap groove 27 on the upper part 8 in the snap bead 26 cylindrical tube 16 engages.
  • the lower end of the cylindrical tube 16 of the closure cap 15 already engages in the annular gap 14 of the outlet bung 2 and the upper end 11 of the upper part 8 of the outlet bung 2 in the second annular gap 20 of the closure cap 15.
  • the packaging container with the closure can then be inserted into a filling machine, where the closure cap 15 is removed again by appropriate devices of the machine before the plastic bag 5 is filled and, after the filling process, is finally closed again by resprinking into the so-called final bounce position.
  • the inner tube piece 13 of the outlet bung 2 is formed in the area of the annular gap 14 with a conical ring surface 29, while the lower end of the cylindrical tube 16 of the closure cap 15 has a conical surface 30 on the inside .
  • These surfaces 29, 30 are sealingly against one another in the final impact position, but a narrow air gap 31 still remains in the annular gap 14.
  • the closure can be closed by turning the closure cap 15.
  • the closure cap 15 by means of the web 22 along the shoulder 12 of the top part 8 are o rotated approximately 90, while a further rotation is prevented by the cam 21 on the closure cap 15th Due to the rotational movement, the opening 17 in the cylindrical tube 16 is moved away from the product outlet tube 9, so that the outlet cross section 10 is closed by the wall surface of the cylindrical tube 16 of the closure cap 15.
  • outlet cross section 10 of the product outlet tube 9 it can be provided that the outlet cross section 10 and the opening 17 in the cylindrical tube 16 of the closure cap 15 are oval. In order to ensure adequate sealing even then the outlet cross section 10 or the opening 17 is then formed with an edge bead on the side facing each other, which is indicated in FIG. 6 by the reference symbol 32. Such an enlarged outlet opening is provided, for example, when the packaging container is used for more viscous media.
  • the invention is not limited to the exemplary embodiments shown in the drawing. Further refinements of the invention are possible without leaving the basic idea.
  • the additional bead 32 for particularly volatile media can also be provided with a round outlet cross section 10 of the product outlet pipe 9 and the like. More.
