Definitions

  • the invention relates to a folding box with a predetermined tear line which, when a pressure is exerted on the folded box, which acts approximately in the longitudinal direction of this predetermined tear line, leads to the formation of a discharge opening which closes again when the pressure is released.
  • folding boxes are known. These folding boxes have no inner lining. The discharge opening is not closed properly due to the plastic deformation of the folding box material, which usually consists of cardboard. As a result, in particular when such folding boxes fall over, there is a risk that the free-flowing or free-flowing material in them can escape through the incompletely closed discharge opening.
  • Folding boxes with inner lining are also known. Depending on the type of material used for the inner lining, it is possible to pack the goods dustproof, greaseproof, water vapor-tight, aroma-tight, liquid-tight or vacuum-tight in these folding boxes.
  • the known folding boxes are provided with a tear-open tab defined by predetermined tear lines.
  • the inner lining is also provided with corresponding predetermined tear lines and glued to the inside of the folding box. When the tear-open tab is torn open, the inner lining is also included crack, creating a pouring spout. The spout opening can be closed more or less tightly by manually pushing back the tear-open tab.
  • the invention relates to folding boxes of the type described in the opening paragraph, i.e. those whose discharge opening automatically closes when the pressure is released.
  • the task is to create a way to largely avoid the imperfect reclosure described above.
  • the folding box is provided with an inner lining
  • that the inner lining is provided with a predetermined tear line, which is located next to the predetermined tear line of the folding box, but at least partially not congruent with it, such that when the discharge opening via at least one faces the two Ausurgiö Stamms edges an inner lining section, and in that the inner lining is connected to the inside of the folding box, wherein the compound is at least g in the region of the protruding inner-liner portion when forming the Aus commonlyöffnun is soluble or at least this range of the connection is excluded.
  • the solution according to the invention makes it possible, when the discharge opening is closed again, to push back the discharge opening edge opposite the inner lining section to such an extent that it snaps behind the resilient inner lining section and is held by the latter in the closed position. So there is a kind of snagging here.
  • By exerting pressure on the folding box again it is possible to open the dispensing opening again without difficulty, the previous one restrained discharge opening edge overcomes the retention force of the lining section and snaps forward again.
  • the protruding inner lining sections which function as a retaining spring can be provided on each of the two discharge opening edges formed by the predetermined tear line or only on one.
  • An expedient development of the invention can consist in the fact that the predetermined tear line of the folding box extends in the case of a cuboid or cubic design of the folding box and the predetermined tear line of the inner lining between two parallel walls of the folding box.
  • the wall of the folding box having the predetermined tear line be provided with grooves or fold lines tapering radially onto a central region of this roller tear line.
  • a first practical embodiment of the invention can be characterized in that the predetermined tear line of the folding box runs straight and perpendicular between the two parallel walls, and that the protruding inner lining section lies approximately in a central region of the predetermined tear line.
  • the protruding inner lining section can then have the shape of a triangle, a circular section or the like.
  • the creasing or folding lines can form in the middle of the predetermined tear line of the folding box crossing diagonals of a rectangle, the two parallel walls of the folding box defining two opposite sides of this rectangle, the folding position of the folding box upper side wall defines a third side, and a further crease or fold line extending below the predetermined tear line and parallel to it defines the fourth side.
  • a further practical embodiment of the invention can consist in the fact that the predetermined tear line of the folding box is designed to be approximately undulating, with a wave crest being located in the middle when the folding box is in the dispensing position.
  • the protruding inner lining section can bridge the indentation formed by its upper edge after the formation of the pouring opening and corresponding to the wave crest.
  • the predetermined tear line of the folding box be designed so that it forms a capped wave crest in its central region, and that the protruding inner lining section is a tongue-shaped extension at the bulge formed by the lower edge of the dispensing opening and corresponding to the capped wave crest .
  • the formation of a pouring spout can be promoted in that a crease or fold line runs downward from the center of the predetermined tear line and runs parallel to the two side walls and ends in two other crease or fold lines which diverging from the mouth run obliquely downwards, the lower ends of the other two fold lines being connected by a further crease or fold line extending parallel to the predetermined tear line.
  • a third practical embodiment of the invention can consist in that the predetermined tear line of the folding box runs essentially straight and perpendicular between the two parallel walls, but in the middle Osition p in Aus well - - having upwardly projecting ledge portion a.
  • the predetermined tear line of the inner lining can run straight and perpendicular between the two parallel walls throughout such that the indentation corresponding to the protruding step formed by the upper edge of the pouring opening is bridged by the protruding inner lining section.
  • the projecting inner lining section can also be a tongue-shaped extension on the bulge formed by the lower edge of the pouring opening and corresponding to the protruding step.
  • the formation of a pouring spout when pressure is exerted on the folding box can be promoted in that from the center of the predetermined tear line of the folding box, a crease or fold line runs parallel to the two side walls downwards and into two other creases - Or fold lines that divergently run downwards from the mouth, the lower ends of the other two crease or fold lines being connected by a further crease or fold line extending parallel to the predetermined tear line.
  • the target tear line of the folding box can be formed by line-shaped punching or punching punctuated by narrow webs.
  • the predetermined tear line of the inner lining can be formed by line-shaped punchings which are sealed until the folding box is opened.
  • the predetermined tear line of the folding box and that of the inner lining are provided on a narrow side of the folding box. This favors the hand Habit and pressure for the purpose of creating a discharge opening.
  • the folding box is labeled 1 in all the figures. It is cuboid. Their two broad sides are labeled 2 and 3. The top side 4 and the front side 5 are also visible.
  • the folding box is made of cardboard and has an inner lining.
  • a predetermined tear line 6 is provided in the upper part of the front side 5 of the folding box 1. This consists of Naturalstanzun g s with narrow webs therebetween.
  • the predetermined tear line 6 is essentially straight and extends parallel to the cover side 4. In the central region, the predetermined tear line 6 has a step 8 protruding upwards.
  • the predetermined tear line 7 of the inner lining runs straight and, except for the preceding paragraph 8, is congruent with the predetermined tear line 6 of the folding box.
  • the front side 5 of the folding box also has creasing or folding lines which are intended to promote the formation of a pouring spout.
  • two creasing or folding lines 11, 12 converge obliquely inwards from the upper corners of the front side 5 to the ends of the projecting paragraph 8 of the folding line 6.
  • Two further folding lines 1 0 , 13 extend from the ends of the preceding paragraph 8 . diagonally downwards.
  • a further crease or fold line 14 runs downwards, which opens into two other fold lines 15, 16.
  • the two fold lines 15, 16 run diagonally downwards. Their ends are connected to each other by a fold line 17 which runs parallel to the top side 4.
  • an indentation 24 is formed in the upper edge of the pouring opening 2o, but is bridged by the inner lining section 9 located behind it. If the discharge opening 20 is now to be closed again, the pressure must be removed from the sides 2, 3 of the folding box 1. The two edges of the discharge opening 2o then move towards each other again. In order to ensure a relatively tight closure, pressure must be exerted with the fingers on the area of the front side 5 below the discharge opening, so that the bulge 23 formed by the lower edge of the discharge opening 2o snaps behind the inner lining section 9. The inner lining section 9 then retains the bulge 23 and prevents the discharge opening 20 from opening again, unless a corresponding lateral pressure is again exerted on the folding box 1. The reclosure achieved in this way is so secure that it remains in place even if it falls over: the folding box.
  • the embodiment shown in Figures 3 and 4 is modified from the embodiment shown in Figures 1 and 2 only to the extent that the predetermined tear line 1o7 of the lining is not straight here, but also has a projecting shoulder.
  • the corresponding inner lining section 109 thus forms a tongue-like extension on the bulge 23 located at the lower edge of the pouring opening 20, which snaps behind the upper edge of the pouring opening 20 formed by the bulge 24o. Otherwise, the function is the same as previously described.
  • the predetermined tear line 2o6 of the folding box 1 wavy, with the wave crest in the middle.
  • the predetermined tear line 207 of the inner lining is also wave-shaped; their wave crest is capped.
  • an inner liner section 2o9 bridges the indentation 224 formed by the upper edge of the pouring opening 2o. Behind this inner liner section 2o9, the bulge 223 corresponding to the crest of the wave can snap onto the lower edge of the pouring opening 2o when it is closed again.
  • the routing of the creasing or folding lines, which is intended to promote the formation of a pouring opening is the same here as in FIGS. 1 and 2.
  • FIGS. 7 and 8 is only modified compared to the embodiment shown in FIGS. 5 and 6 in that the predetermined tear line 307 of the inner lining describes a complete wavy line, while the wave crest of the predetermined tear line 306, the folding box 1, is capped.
  • the predetermined tear lines of the folding box and the inner lining are congruent except for the region of the wave crest in the middle.
  • the predetermined tear line 406 of the folding box 1 is a straight line which extends in the upper part of the front side 5 parallel to the cover side 4 between the two side walls 2, 3.
  • the nominal tear line 4o7 of the inner lining runs largely congruent with the nominal tear line 4o6 of the folding box 1, except for a central region which forms a triangle pointing downwards.
  • this middle region forms an inner lining section 409 protruding from the upper edge of the pouring opening.
  • the pouring opening 2o is closed again, the lower edge of the pouring opening can be pressed behind the protruding inner lining section 4o9.
  • two diagonal crease or fold lines 425, 426 are provided here, which start from the upper corners of the front side 5 and run through the center of the predetermined tear line 4o6.
  • the lower ends of the two creasing or folding lines 425, 426 are connected by a folding line 427 which extends parallel to the cover side 4.
  • the predetermined tear line extends 5o6 of the lining just as in the intended tear line 406 in accordance with Figures 9 and 1 0, namely straight and parallel to the top side 4 of the folding box 1.
  • a difference from the in Figures 9 and 1o shown embodiment consists only in that a central region of the predetermined tear line 507 of the inner lining here forms an upward triangle. This upward-pointing triangle defines an inner lining section 509 which protrudes from the lower edge of the discharge opening 2o.
  • the creasing or fold lines are in the embodiment according to Figures 11 and 12 are the same as in the embodiment in Figures 9 and 1 0th
  • the lining is usually glued to the inside of the folded box orwithversie g elt. Except for this is the protruding lining section and, if necessary, an area in its vicinity.
  • the protruding inner lining section can, however, only be glued to the inner wall of the folding box in such a way that it comes loose when pressure is exerted on the folding box.
  • a retaining tongue made of elastic foil which protrudes beyond the edge, can be attached, which is made of the same material as an inner lining, for example.
  • the principle of the invention can even be used in folding boxes with a tear-open flap which can be opened after being torn open and which opens a dispensing opening which can be closed again by folding back the tear-open flap.
  • a retaining tongue protruding from the edge made of elastic film can be attached behind the edge of the tear-open tab and / or the pouring opening on the inside of the tear-open tab or the pouring opening.
