Definitions

  • the invention relates to a packaging made of a folding box with walls made of foldable material, in particular cardboard, with an inner liner and with a tab arranged in the region of the inner liner, which can be pulled out of at least one wall of the folding box to form an opening.
  • Packaging of this type in which the packaged goods are covered by the inner lining, which in turn is protected by the packaging carton, are known. They are used in particular for foods in order to protect them, possibly even to keep them sterile, to protect them from drying out or to protect them against foreign smell and / or taste. This means that the goods to be packaged are hermetically sealed.
  • folding tabs are usually glued to one another on a narrow side of the folding box, and these must be separated from one another and opened up to open them. Access to the content is then not yet possible because the inner lining is still closed like a bag.
  • the welded or glued end of the bag must be pulled out and cut open with a tool such as scissors.
  • tearing with your fingers is not possible because the inner lining is made of a very tough, tear-resistant material. Cutting open with a special tool such as scissors or a knife is cumbersome for buyers. If the inner lining located inside the folding box can be torn open, there are ugly tears, which is particularly annoying when the contents of the packaging are stored in the packaging and, for example To be offered to guests.
  • flat chocolate packaging in which a tear-open tab is provided in the top cover side of the folding box by punching.
  • the flap is dimensioned such that it exposes most of the top side when opening and only leaves a narrow edge area on the side.
  • the inner lining is exposed.
  • the inner lining must be torn open with the fingernails or cut open with scissors.
  • Another disadvantage of the known packaging is that it is difficult to close it again after tearing or opening.
  • the part of the inner lining to be torn was already glued to the corresponding part of the folding box to be torn open, that is, the flap thereof.
  • the folding box is torn open along its cardboard tear line
  • the thin-walled inner lining that is then necessary is also torn along its inner tear line.
  • Such folding boxes are used for example for wipes or the like.
  • a cardboard blank for the folding box is laid out flat and then covered and glued with the inner lining blank, which is also laid out flat, for the inner lining. Then or before, the opening is the tab pre-punched into the cardboard blank, possibly punched. Then the cardboard blank and the inner lining blank were folded and glued.
  • the inner lining blank because of the poor accessibility to the edge areas forming the adhesive or weld seam of the inner lining blank, it is not possible to ensure the hygroscopically required tightness.
  • a hygroscopically tight gluing or sealing has so far only been possible if the inner lining blank is glued or sealed to form a tube outside the cardboard blank before it is inserted and glued into the folding box, since the seam to be formed is then accessible to a suitable extent.
  • the tube formed in this way can also be glued to a flat cardboard blank, wherein the cardboard blank can have a pre-punched pouring opening.
  • Such packaging has the disadvantage that a pre-punched pouring opening can only be located in the cardboard blank and when the tab is torn open it is not guaranteed that an adhered area of the inner lining blank will also be entrained. Rather, there are irregular tearing open, the inner lining blank not being torn open at all, is, so that piercing or cutting is required as before.
  • the window openings provided in the folding box have proven to be disadvantageous because the nonwoven material that has been pulled through can get stuck when it is removed from the window opening and thus the intended function that a cloth takes the next one with it when it is pulled out is no longer guaranteed .
  • folding boxes have been provided for the packaging of paper towels, in which a relatively large pre-punched opening of the carton is covered with a plastic film as the inner lining, which has a smaller window opening. This plastic film is relatively soft; there is then no danger that the solid paper towel will tear at the window opening.
  • an adhesive such as a glue
  • a part of the plastic film is torn out and the finished opening in the plastic film is only created at this point.
  • the object of the invention is accordingly to provide an easily producible packaging of the type described in the introduction, in which it is not necessary to tear open the inner lining or to use a tool to open it.
  • the open inner lining should also be elegant and should not have a negative impact on the aesthetic feeling of the buyer. Furthermore, a method for the production is to be specified.
  • the inner lining is torn along along its (first) predetermined tear line.
  • the inner lining is therefore expediently glued or sealed to the inside of the tab in the window area with its outside.
  • the inner lining is provided with an application of a wick mass along the edge of the predetermined window.
  • This wick mass has an adhesive effect, but the adhesive bond can be easily removed again by slowly pulling it off. It is particularly suitable for such a wicking mass of adhesive wax.
  • This application of the wick mass can be applied not only to the inner lining in the window edge area, but also to the inside of the flap. It is essential that at least the inner lining or the tab is provided with this order, so that a sealing connection is created by pressing the tab against the inner lining.
  • the tab can move at certain points as a result of bumps and at some points along its own second predetermined tear line come loose from the wall of the folding box. Is the window area of the If the inner lining was glued to the flap, the inner lining would be pulled along within this window area and tear open along its first predetermined tear line. Due to the wick mass, which causes an adhesive connection between the outer edge of the window and the tab, the window border is pulled along with a small movement of the tab, so that the first. Target tear line of the inner lining is not loaded. The inner lining opens along the first predetermined tear line to a window only when the flap of the folding box is deliberately torn open. With this deliberate tearing open the easily releasable wick mass does not form an essential obstacle against tearing open.
  • the application of the wick mass can not only extend around the window area on the outside, but also protrude into the window area. This configuration gives an even higher security against unwanted tearing open. Furthermore, reclosing is facilitated if the wick mass extends into the window area on the tab, because then the tab does not have to be placed geometrically exactly on the open window of the inner lining to close.
  • the window of the inner lining will be smaller than the flap of the folding box and completely covered by the flap.
  • Another advantageous embodiment of the invention provides that the window area of the inner lining enclosed by the first predetermined tear line protrude on at least one side beyond the corresponding boundary line (second predetermined tear line) of the tab.
  • This area of the inside that extends beyond the edge of the tab futters is pressed slightly downwards on reclosure of the package, he places because of its elasticity e I genes on the inside of the wall of the folding box and thus serves as a resilient snap-in element, which prevents the flap from jump by itself.
  • the window area of the inner lining can be fastened over the entire surface or only at certain points on the inside of the tab. Glue can be used for attachment. If the inner lining is made of a suitable material, the window area of the inner lining can also be sealed on the inside of the flap.
  • the tab can already be punched out of at least one wall of the folding box, but it is preferably provided with its own second predetermined tear line in the corresponding at least one wall.
  • the predetermined tear lines for the window in the inner lining and also for the flap in a wall of the folding box are preferably produced by punching. "Punching” is understood to mean a notch which does not yet result in the inner lining or the carton breaking or cutting at the punched point. Another possibility for the predetermined tear lines is that they are formed by a perforation. A combination is advantageous in which the inner lining for the window area has such a perforation as a predetermined tear line and at the same time an application from the wick mass extending into the window area is provided. In this case, the wicking material closes the perforation holes, so that the simple creation of the predetermined tear line means that there is no disadvantage with regard to the tightness of the inner lining.
  • the predetermined tear line of the inner lining can be wave-shaped if this is desired for design reasons of the packaging.
  • predetermined tear lines are formed by straight-line stamping sections along the predetermined tear line, which alternate with bridge sections lying in between. Such predetermined tear points for foils are produced with rotating punching tools. These linear stamping sections are formed by punching.
  • predetermined tear lines can only be provided for small foils and small tear-open or window openings. If the known target tear lines are used for large foils with large window openings, such as are common for praline packaging in which the window opening extends over almost the entire lid area of the praline packaging, the large foil cannot be processed, but rather breaks during processing along the nominal tear line. This disadvantage is particularly serious when thin films are to be used.
  • the invention enables a predetermined tear line, in which the inner cut of the inner lining is torn open along the predetermined tear line through the flap of the folding box, particularly when the hook-shaped sections consist of a straight part and an angled part thereof, the angled part the (first) target tear line intersects against the tear direction. It is therefore possible to tear open a wide area, even starting from a small handle, perfectly and cleanly.
  • the tab that can be torn open is usually pressed inward along the perforations of its second predetermined tear line together with the inner lining in the region of the window opening, which should also have perforations according to the first predetermined tear line which gives access to the inside of the carton.
  • a disadvantage is then the flap inside the folding box and can either clog the opening formed by tearing or be poured out together with the goods, which is undesirable. Rather, it is desirable that the tab can be conveniently torn outwards.
  • a rigid hopper is formed, which can be pushed in and pushed out by means of rigid walls after the tab has been torn open.
  • a punched-out recess starting from the second predetermined tear line is advantageously provided in the stamped-out region of the wall. The recess can be gripped very easily by the finger, so that the tab can be torn open to the outside without difficulty, possibly even without damaging the inner lining if it is not glued to the tab. If, on the other hand, the inner lining is glued to the flap, the inner lining is torn open at the same time as the flap is torn open.
  • Such an arrangement has advantages in particular in the case of folding boxes with a collapsible lid, the tab being able to be provided in a wall which is lowered relative to the latter.
  • FIG. 1 shows a first embodiment of a packaging according to the invention. It consists of a folding box i formed by walls 11, 14, 24, in which an inner lining 2 is attached.
  • This inner lining 2 can be designed as a bag which surrounds the goods to be packaged on all sides, but it is also conceivable that this inner lining 2 extends only over certain areas of the inside of the box.
  • FIG. 1 shows the packaging according to the invention in the open state.
  • the window section 15 of the inner liner 2 is entrained, so that it separates from the inner liner 2 along the first predetermined tear line 4 and a window 5 is formed in the inner liner 2.
  • the first predetermined tear line 4 corresponds to the edge of the window area 15.
  • An order 9 from a wick mass covers this edge. This wick mass is thus both inside the window area 15 and outside, it serves to reclose the packaging.
  • the flap 3 is folded down again (FIG. 1) into its original position and pressed down a little so that the wick mass 9 lies against the inner lining 2 and thereby closes the window 5.
  • Fig. 2 shows an embodiment in which the tab 3 is provided with a fold lo, which makes it possible to fold the tab 3 which has been torn out or pulled out to form a chute.
  • the inner lining 2 and the window region 15 torn out of the inner lining 2 are shown hatched.
  • To reclose the tab 3 is shaped flat again so that the edge 7 of the tab 3 coincides with the second predetermined tear line 6 in the wall 14 again.
  • Fig. 3 shows a section through a packaging according to the invention.
  • the wall 14 is provided with the second predetermined tear line 6 by punching.
  • the second predetermined tear line 6 delimits the tab 3.
  • the inner lining 2 is located on the inside of the wall 14. This inner lining 2 is glued in the window area 15 provided with an adhesive layer 8 to the inside of the wall 14 of the folding box 1. The window area 15 is delimited by the first predetermined tear line 4 in the inner lining 2.
  • FIG. 4 shows a development in which the wick mass 9 is arranged on the outside of the window area 15 between the inner lining 2 and the tab 3.
  • the wick mass 9 can be fastened on the tab 3, but it can also be located on the edge area of the inner lining 2 surrounding the window 5.
  • FIG. 5 again shows the relative position between the window 5 or the first predetermined tear line 4, which is indicated in FIG. 5 by a chain line.
  • the tab 3 is torn out of the wall 14 along the second predetermined tear line 6.
  • the wick mass 9 can be applied as a frame between the edge of the flap 3 and the window defined by the first predetermined tear line 4 opening 15 may be arranged; In the case of the example shown: the wick mass 9 on the tab 3 extends inwards into the window area 15.

  • the first predetermined tear line 4 of the inner lining 2 and the second predetermined tear line 6 in the cardboard blank to form the flap 3 are not designed to run in the same direction or are essentially the same. Rather, the first predetermined tear line 4 has a course which crosses that of the second predetermined tear line 6 several times, so that edge regions 18, 19 are formed in which the area lying within the first predetermined tear line 4 lies over the area lying within the second predetermined tear line 6, ie the flap 3, survives.
  • Areas 21, 22 are therefore formed outside the predetermined tear line 4 and beyond the sections 25, 26, in which the tab 3 protrudes near the fold 23, that is to say there is considerably wider than the area 27 defined by the predetermined tear line 4.

This results in two different tear-open directions 14. Starting from this grip tongue 45, the alignment of the curved parts 49 of the punching sections 46 is opposite to one another, so that a wide grip tear-open can be carried out properly and cleanly from a small grip tongue 45.
  • the punched sections 46 in the inner lining are only punched sections, which makes it possible to process even very thin foils even with large tear-open openings (window section 15).
  • Punching is understood to mean a punching process in which the punching tool does not cut the film, but rather provides corresponding anchor bends or notches in it. In this way, the hermetic seal of the goods to be packaged is ensured.
  • FIG. 11 also shows the use of hook-shaped punching sections known for cardboard blanks (cf. also detail XI in FIG. 10a). However, for the reasons mentioned, these should not interlock in carton blanks and are therefore only used Delimitation of tear strips 43 used.
  • the first predetermined tear line 4 designed in the manner explained therefore makes it possible not only to provide window sections 15 in the inner lining 2 for small inner linings 2 and small tabs 3, but also for large-area inner linings 2 and tabs 3 and very thin foils.
  • FIG. 12 shows a blank for a folding box according to a first exemplary embodiment.
  • the blank according to FIG. 1 consists on the one hand of a cardboard blank 51 and on the other hand an inner lining blank 61 glued thereon in a specific positional relationship to this.
  • the blank according to FIG. 12 is intended for a folding box with a cuboid structure (FIGS. 1 and 2).
  • the invention is also basically applicable to folding boxes and packaging of other structures.
  • the cardboard blank 51 according to FIG. 12, in a manner known per se, consists of a plurality of rectangular surfaces formed by fold seams separated from one another and flaps attached to these, which are folded against one another and glued to one another in such a way that the cuboid-shaped folding box is formed here. Since such folding boxes are known per se, a detailed explanation of all details of the folding box and appears its cardboard blank unnecessary, which are not of interest for the present invention.
  • the cardboard blank 51 has a total of five sections separated from one another by fold seams, and after folding around the fold seams, the two edge sections 52 and 54 are glued to one another in an overlapping manner.
  • the former edge section 52 is the inner edge section when glued and the edge section 54 is the outer edge section when glued.
  • the outer edge section 54 usually has the width of the corresponding cuboid side of the folding box for aesthetic reasons, it is sufficient if an overlap with the former edge section 52 is ensured.
  • a second predetermined tear line 6 is provided in the cardboard blank 51 for a removal opening.
  • this second predetermined tear line 6 is located in the cuboid side (wall 14) of the folding box, which lies opposite the one formed by the overlapping edge sections 52 and 54.
  • the inner lining blank 61 On the inside of the cardboard blank 51 is the inner lining blank 61, expediently only glued to the wall sections thereof.
  • the inner lining blank 61 is essentially rectangular and protrudes beyond the area of the wall sections of the carton blank 51 into the area of the flaps thereof. What is essential here is the special positional assignment between the cardboard blank 51 and the glued-on inner lining blank 61.
  • the edge region 62 of the inner lining blank 61 associated with the former edge portion 52 of the cardboard blank 51 protrudes beyond the side edge of the edge portion 52.
  • the other edge area 63 of the inner lining cut 61 assigned to the other edge section 54 of the cardboard blank 51 protrudes beyond the fold line 53 assigned to this edge section 54.
  • the respective protrusion is expediently dimensioned so wide that gluing or welding can be carried out, as will be explained in more detail below.
  • the inner lining blank 61 is glued to the cardboard blank 51, it is also possible to provide a punching along the first predetermined tear line 4 for the removal opening in the inner lining blank 61.
  • the punching lines for the second predetermined tear line 6 in the cardboard blank 51 and the first predetermined tear line 4 in the inner lining blank 61 are not congruent, it is expedient if the area between the two predetermined tear lines 4 and 6 when gluing the cardboard blank 51 and lining blank 61 is not covered with adhesive.
  • a strip of an adhesive 64 is applied to the side of the edge region 62 of the inner lining blank 61 facing the cardboard blank 51 and the blank 51, 61 is then ver arc, that the side edge of the edge region 62 of the In nenfutterzuitess 61 adjacent the other edge region 63 of the lining blank 61 comes to lie at the level of the fold line 53rd In the case of a cuboid folding box, this is done by folding around a fold line 57 which is the next but one fold line from both the side edge of the edge section 52 and from the fold line 53 next to the other edge section 54 of the carton blank 51.
  • the other edge region 63 of the inner lining blank 61 is folded around the lateral edge of the former edge region 62 onto the adhesive 64 thereon. This can be done together with the folding of the edge section 54 around the fold line 53 onto the edge section 52 of the cardboard blank 51.
  • a tight connection is first of all ensured by means of the adhesive 64 between the two edge regions 62 and 63, for example a pressure roller or the like is guided over the overlap region formed in this way.
  • the cut 51, 61 in the exemplary embodiment according to FIG. 13 differs from the cut 51, 61 of the exemplary embodiment according to FIG. 12 essentially only in that, for the same dimensions, the side edge of the inner lining blank 61 assigned to the edge region 62 is different from that of the edge portion 52 of the carton blank 51 adjacent fold line 58 is further away by approximately the width of the overlap area between the edge areas 62 and 63 of the inner lining blank 61.
  • the two edge regions 62 and 63 of the inner lining come after the bending, which is done here in the same way, about the folding line 57 blank 11 to overlap each other. In this way, a tight connection can be made between these edge regions 62 and 63 at the sections which are now opposite one another.
  • this tight connection takes place by means of a sealing seam 65.
  • the edge region 63 of the inner lining blank 61 is expediently not glued to the assigned edge portion 54 of the cardboard blank 51. Therefore, the edge portion 54 of the cardboard blank 51 can be folded outward about the fold line 53, which allows access to the overlap area from both sides, such that sealing tools such as sealing wheels or the like are used to form the sealing seam 65 and are guided along the sealing seam 65 can. In this way, a secure and tight seal of the inner lining blank 61 in the edge regions 62 and 63 can be achieved, even if the inner lining blank 61 is already glued to the cardboard blank 51.
  • the overlap region formed by the edge regions 62 and 63 of the inner lining blank 61 which are connected to one another by means of the sealing seam 65 is folded or folded in the direction of the edge portion 52 of the cardboard blank 51. This can be done together with the folding of the edge section 54 around the fold line 53 (FIGS. 20 and 21).
  • an adhesive connection can also be achieved here, a suitable adhesive being achieved in a corresponding manner on at least one of the parts of the edge regions 62 and 63 which face each other after folding and by pressing the edge regions 62 and 63 against one another after the folding.
  • the area between the edge area 63 of the inner lining blank 61 and the edge portion 54 of the cardboard blank 51 must not necessarily be free of adhesive, because folding away the edge portion 54 is not necessarily necessary, as when producing a sealing seam 65.
  • the edge region 52 of the carton blank 51 can have an additional surface 60 which is designed such that the edge region 62 protrudes beyond the edge portion 52 or its additional surface 6o approximately, but at least corresponds to the width of the overlap region of the edge regions 62 and 63. Then, as shown in FIG. 22, the sealed (or glued) edge regions 62, 63 can be folded over the side edge of the additional surface 60 to form the fold such that the fold formed including the sealing seam 65 (or including the corresponding adhesive area) is clamped between the edge section 54 and the additional surface 6 0 of the edge section 52.
  • the inner edge section 52 of the finished folding box also has end flaps 55 which can be glued to corresponding end flaps 56 of the outer edge section 54 of the cardboard blank 51.
  • FIG. 23 This is shown in perspective in FIG. 23.
  • the flaps of the cardboard blank 51 are folded outwards after the inner and outer edge sections 52 and 54 have been glued and the tube-like structure thus reached has been opened or opened, so that access to the edge regions of the inner lining blank 61 is possible. It turns out that if the flap 55 of the inner edge section 52 were not set back relative to the side edge by the overlap width of the edge regions 62 and 63 of the inner lining blank 61, then after the flap arrangement had been folded out of the flaps 55 and 56 it would no longer be possible and thus access to the edge areas of the inner lining blank 61 would also no longer be possible.
  • the invention thus enables the production of blanks for, in particular, rectangular folding boxes, in which hygroscopic tightness of the inner lining is ensured in spite of simple manufacturability, and in addition, a punching (window 5) for a pouring opening or the like is also provided in the inner lining blank 61 for the inner lining 2. can be attached.
