Definitions

  • the invention relates to a folding box for pourable goods, in particular for liquids, with a folding flap that can be folded up on the bottom and lid side and has a tubular folding jacket made of cardboard or cardboard, in which a substantially tubular bottom and lid side folds in and can be closed with a sealing joint in each case is made of sheet material.
  • Folding boxes of the type described above in contrast to sheet metal or plastic containers, have the basic advantage that they can be delivered and stored in a space-saving manner when folded. After use, emptied folding boxes can be effortlessly compressed, again stored in a space-saving manner and can also be burned or left to rot with little residue.
  • the inner lining consists of a foil-like material, such as polyethylene foil or aluminum foil.
  • the inner lining has an outwardly projecting longitudinal sealing joint, so that there is a tubular structure which is initially open on the bottom and lid sides and which is held on the inner wall surface of the approximately tubular cardboard or cardboard folding jacket - together with this for storage purposes - with several adhesive points .
  • the carrier film eg aluminum film
  • the carrier film is provided on the inside with a sealing layer, for example a heat seal layer.
  • a sealing layer for example a heat seal layer.
  • the tubular inner lining is first covered with a bottom egg seal seam or seal joint. Then the cardboard or cardboard folding flaps are folded and glued on the bottom, whereupon the contents are introduced, the lid-side sealing seam of the tubular inner lining is produced and finally the cardboard or cardboard folding flaps on the lid side can be folded and also glued.
  • the folding box described at the outset which has become known through prior public use, is used, for example, to hold motor oil and is provided as a tear-open pack with a lid-side tear-open tab which at the same time forms a pouring opening in the inner container when it is torn open.
  • the known folding box described at the outset is particularly suitable for those applications in which - as is mainly the case with motor oil - the entire contents are used up all at once.
  • the known folding box is extremely disadvantageous because it has no or at most a makeshift - e.g. by taping with adhesive tape - reclosure allowed.
  • partial consumption with subsequent reclosure is necessary for a large number of bulk goods, e.g. for cooking oil or hygroscopic granules, regularly requested.
  • the invention is aware of the disadvantages of the known task of creating a folding box that allows a reusable liquid and gas-tight seal with simple means. According to the invention, this was The object is achieved in that at least in the cover-side sealing joint of the inner liner is sealed an outlet end provided with a closure part, which has at least one gusset-shaped shoulder on its outer surface, which, filling a gusset-shaped transition gap between the liner foil and outlet nozzle, has its free gusset edge in the sealing joint protrudes.
  • the cover-side sealing joint of the inner lining is being produced, an outlet connector previously inserted into the joint opening is sealed at the same time.
  • the sealing is expediently carried out by means of two heated sealing jaw tools which can be moved together and pressed against one another.
  • the invention has solved this additional problem while maintaining a simple design in that the outlet nozzle has at least one gusset-shaped shoulder on its outer lateral surface, which, filling a gussel-shaped transition gap between the lining film and the outlet nozzle, projects with its free gusset edge into the sealing joint. Because of the features according to the invention described above, it has become possible to seal the transition points of the sealing joint adjoining the outlet connections in a completely liquid-tight and gas-tight manner.
  • sealing joint includes all comparable joints, such as welded joints, heat-sealed joints or adhesive joints.
  • the outlet nozzle In the event that the outlet nozzle is used directly at one end of the lid-side joint opening of the inner lining, it may be sufficient for the outlet nozzle to have on its outer lateral surface only a gusset-shaped extension which protrudes toward the middle of the box into the sealing joint. In the event that the outlet nozzle is arranged just a little away from one end of the joint, it has been found to be appropriate, according to further features of the invention, to provide a gusset-shaped extension on the outer lateral surface of the outlet nozzle at two diametrically opposite points. The two diametrically opposite, gusset-shaped approaches then protrude - each gusset-shaped approach by themselves - into the adjacent sealing gap by sealingly filling the respective gusset gap in the sealing gap.
  • the gusset-shaped approach as a one-piece, integral part of the spout forming a plastic injection molded part, with concave connection areas extending on both sides parallel to the free gusset edge smoothly merges into the outer surface of the spout.
  • the smooth transitions also allow the lining film to be applied tightly to the outlet nozzle during the sealing process.
  • a weld between the Internal coating of the lining film or between the film itself and the outlet connection area of the sealing film it has been found to be expedient to provide the same material.
  • the lining foils themselves and their inner coating as well as the outlet spout itself can be made of polyethylene.
  • the invention further provides that the outer surface area of the outlet connector at least at the approximately 90 or 180 degrees of circumference from the gusset-shaped attachment has a convexly rounded cross-sectional contour.
  • the simplest way of fulfilling these features of the invention is that the outer lateral surface of the outlet connector which carries the gusset-shaped attachment or the gusset-shaped attachments essentially has a circular cross-sectional contour.
  • each gusset-shaped attachment measured parallel to the central longitudinal axis of the outlet connector corresponds approximately to the width of the sealing joint.
  • the releasable closure part which closes the outlet opening of the outlet connector can consist of a threaded cap known per se or, for example, of a snap-lock cap or of a known snap-lock plug.
  • the closure part is a threaded cap, gagging of the film-like inner container when unscrewing the threaded cap must be avoided.
  • the invention provides that the outlet connection between the sealing joint and its outlet opening or below the sealing joint (in the latter case: inside the inner lining) forms anti-rotation surfaces.
  • the folding box for liquids shown in FIG. 1 is designated overall by the reference number 10.
  • the folding box 10 initially consists of an approximately tubular folding jacket 11 made of cardboard or cardboard, which has folding flaps which can be folded and glued on the bottom and lid side. From Fig. 1 only the lid-side folding tabs 12, 13, 14 and 15 can be seen.
  • An essentially tubular bottom and cover-side fold-in and essentially closable inner lining 16 made of film-like material is held within the approximately tubular folded jacket 11 made of cardboard or cardboard.
  • the sealing joint 17, which e.g. is filled by a heat seal adhesive, is located between two sealing edges 18 and 19 of the tubular inner lining 16 on the cover side.
  • the outlet connection 20 has an external thread for this purpose provided approach 22, on which the screw cap 21 shown in FIG. 1 (see also FIG. 5) can be screwed on.
  • An essential area of the outlet connector 20 consists of its outer lateral surface 23, which has a mainly circular cross-sectional contour. From the outer jacket surface 23 of the outlet nozzle 20 forming a plastic injection molded part, a gusset-shaped attachment 24 protrudes in one piece and is integrally connected at two diametrically opposite points. It can be seen particularly clearly from FIG. 2 that each gusset-shaped extension 24, filling an unspecified gusset-shaped transition gap between the sealing edges 18, 19 and the outlet connection 20, projects with its respective free gusset edge 35 into the sealing joint 17.
  • each gusset-shaped extension 24 with concave connection regions 25, 26 extending parallel on both sides to the free gusset edge 35 smoothly merges into the outer lateral surface 23 of the outlet connector 20.
  • This gusset design with the smooth transition points allows a tight liquid and gas-tight sealing with the outer surface 23 of the outlet connector 20 into the sealing joint 17.
  • each gusset-shaped extension 24 approximately equal to the width b of the sealing joint 17.
  • the outlet connection 20 is, due to the flexibility of the inner liner 16, attached to the inner liner 16 by the seal in a space-articulated manner.
  • This arrangement basically allows pivoting in and out in accordance with the curved double arrow denoted by y in FIG. 1.
  • This arrangement according to the invention basically allows two different embodiments. Firstly, the embodiment according to FIG. 4, according to which the outlet connection 20 is pivoted inward along the arrow y and is stored within a free storage space on the cover side within the folded casing 11 of the folding box 10 and the cover arrangement is then closed.
  • the key surfaces 28 arranged between the outlet opening 31 and the sealing joint 17 are formed overall by a screw head-like hexagon 32, at the edges thereof, approximately in the middle at the axial height x of the key surfaces 28 groove-shaped depressions 33 are provided.
  • the fork-shaped reveals 29, 30 of the cover-side folding tabs 12, 15 can engage, so that in this way an axial securing of the hexagon 32 - and thus its continued protection against rotation - is effected.
  • FIG. 5 shows a folding box 10a, in which the outlet nozzle 20 with threaded screw cap 21 is accessible from the outside from the beginning.
  • the cardboard or folding jacket 11 therefore does not need to have any separate storage space for accommodating the outlet connection 20 which is otherwise kinked according to FIG. 4.
  • the cover arrangement of the folding jacket 11 differs from the exemplary embodiment according to FIG. 1 only in that no tear-open tab 27 is provided from the beginning.
  • 5 has an essentially plate-shaped extension 34 (only partially shown), which is supported in a manner not shown on the inner lateral surface of the cardboard or cardboard folding body 11 and thus protects against rotation Gagging the closure assembly with the outlet nozzle 20 causes.
  • the plate-shaped extension 34 can also be arranged below the sealing joint 17 on the outlet connection 20 and, with the interposition of the inner liner 16, can be supported on the inner wall surfaces of the folded jacket 11 in a rotationally securing manner.
  • outlet opening 31 of the possibly previously sealed-in outlet connector 20 is also possible to use as a filling opening for introducing the filling material.
  • the central longitudinal axis of the outlet support 20 is designated by a.
