Definitions

  • the invention is directed to a device for handling rectangular packaging containers made of cardboard or material with the same effect, which have a fold closure on the end, the outer corners of which protrude laterally from the end face form a folded triangle, the base of which corresponds to an end face edge and the tip of which is fixed to the parallelepiped side face, which has a slot guide for receiving a part of the closure fold and a cutting knife overlapping the slot guide.
  • Packaging containers made of coated cardboard or material with the same effect are very popular. They are easy to manufacture, easy to handle before filling and can be removed in a particularly environmentally friendly manner after use.
  • the packaging container is folded from a single cardboard blank.
  • the upper and lower end faces are folded into a closure and then welded or glued.
  • the end faces protrude laterally in the form of a folded triangle. This is either folded over on the end face or placed on a cuboid side face and fixed, for example glued, in this contact position. This creates a cuboid shape that is easy to pack and can easily be stacked in units of several individual containers.
  • a folding triangle is generally released from its fixation, folded up and cut off. This creates an opening through which the liquid content can be poured out. As long as the container is closed, it will maintain its cuboid shape if handled properly. However, if it is open, it can be pressed together relatively easily, especially when carelessly handled, so that the liquid escapes. Scissors are generally required to open the container, ie to separate a folding triangle to form a pouring opening, since a knife is too impractical.
  • a flat plate has already been proposed, which has a slot in its longitudinal direction, which is spanned by a knife blade in the region of its one end.
  • One corner of the folded-up closure fold is passed through the slot and then the plate is pulled away sideways so that the knife blade separates the corner protruding through the slot.
  • this measure is only a replacement for an otherwise necessary pair of scissors, without offering any further advantages in use.
  • it is desirable not only to be able to open the packaging container, but also to be able to handle it better for further use, in particular for emptying.
  • a frame which at least partially encompasses the cuboid on four side surfaces, which has a handle oriented approximately perpendicular to the plane of the frame with a catch for reaching under a folded triangle folded onto the cuboid side surface and in another frame leg has the slot guide with the knife.
  • the Cutting device is therefore no longer an insulated device, as in the previously known device, and can only be used as such, but part of a supporting frame for receiving the packaging container.
  • the frame bears the packaging container, which has little dimensional stability, especially after opening, with the handle particularly favoring handling.
  • the cutting device is provided on the frame in such a way that the cutting process can be easily carried out on the handle when the frame is gripped. If the packaging container is inserted into the frame after opening, the catch engages under the folding triangle fixed on this cuboid surface and thus leads to a firm connection between the frame and container so that it can no longer slide down out of the frame.
  • the device can be manufactured in different sizes, which are adapted to the respective cardboard cross-sections.
  • the frame has two frame legs which lie against the entire width of the respective cuboid surface and two shorter frame legs adjoining this.
  • the frame does not completely enclose the packaging container, but grips it on four sides, it lies fully on two sides of the container and partially on two sides.
  • the frame is therefore open and can be pushed onto the packaging container more easily in this way.
  • the handle of the frame is expediently arranged on a frame leg corresponding to the entire width of a cuboid surface. In this way, there is a particularly high degree of stability when handling the device holding the packaging container.
  • the frame additionally has a further leg, which in use rests on part of the cuboid end face, and this is provided with the slot guide with a cutting knife.
  • the slot guide in a frame leg which lies against an entire cuboid area. In the case of packaging containers with a rectangular basic cross-section, this is preferably the frame leg that lies against a wide cuboid area.
  • Such a slot guide can then be made long enough to facilitate the insertion and cutting of the fold closure. It has proven to be particularly advantageous to make the arrangement so that the slot guide continues into the subsequent short frame leg. As a result, the frame having the slot guide can be easily guided over the severed part when the closure part is cut off after it has been cut off.
  • the free end of at least one of the short frame legs is slightly angled or bent outwards, so if it projects outwards, it is much easier to push the frame onto the opened packaging container.
  • the knife blade spanning the slot guide can be attached directly to a frame leg.
  • a rivet or screw fastening is suitable for this, a detachable clip or the like closure can also be used. It has proven to be particularly advantageous within the scope of the invention, however, to attach the knife blade to a separate knife holder arranged on the frame leg. Because the knives blade is a wearing part that may need to be replaced, such a knife holder makes handling considerably easier.
  • the knife holder can be hinged to the frame leg and can be folded onto the outer surface of the leg and locked there. In such a case, the knife holder covers the cutting blade on both sides of the slot guide and gives it a reliable holder. It is particularly useful if the knife holder is integrally formed with the frame leg. This significantly simplifies the manufacture of the device and contributes to reducing the manufacturing costs.
  • the versatility of the device according to the invention can be increased further in that the knife blade protrudes over a longitudinal edge of the frame leg. It can also be used for other purposes, for example for cutting open a packaging box. Its arrangement on the frame makes it look like a drawing knife.
  • the safety of use of such a device is substantially improved if a protective surface which projects beyond its contours and is at a distance from the knife blade is arranged on the inside of the protruding knife blade facing the frame leg. This covers the protrusion of the knife blade and thus eliminates the risk of injury from this knife part. Due to the distance between the protective surface and the knife blade, a packaging box can be cut open directly along an edge in the aforementioned application of the device. The protective surface of the cardboard edge immediately adjacent to the cut lies here.
  • a protective cap that can be attached to the protruding knife blade.
  • This can, like the invention further provides for a plate which can be inserted into the space between the knife blade and the protective surface and which has ribs surrounding the protruding knife blade on its outer surface. This cap is clamped by inserting it into the distance between the knife blade and the protective surface. The ribs shield the knife, especially the cutting edge, so that there is practically no risk of injury.
  • the device according to the invention can, for example, be formed from a sheet metal plate, appropriately bent.
  • the frame and handle can consist of one piece.
  • the invention also permits the manufacture of the device from plastic, expediently by injection molding, the frame and handle, and possibly also the knife holder integral therewith, being formed in one operation. This solution also makes it possible to connect the frame and the knife holder with a film hinge.
  • the packaging container 1 indicated in Fig. 1 has a cuboid shape, which is formed from the two end faces 2 and 3, the two wider side surfaces 4 u. 5 and the two narrower side surfaces 6 u. 7.
  • the two end faces 2 u. 3 each have a fold closure 8, which may be tightly welded.
  • the fold closure is formed 8 laterally projecting corners are formed, each of which results in a folded triangle 9 (end face 3) or 10 (end face 2), which in the case of the end face 3 has the narrow side faces 6 or 7, in the case of the end face 2 of this and there, for example are fixed by gluing.
  • the folding triangle 9 is released from its fixation, bent upwards in the direction of the arrow 11 and cut off. Then the container contents can be removed, e.g. be poured out.
  • the device serving this and other handling of the packaging carton 1 consists of a frame 12, the longer leg 13 of which has a wide side surface 5 and its shorter leg 14 abuts a narrow side surface 7 of the packaging carton 1 over its full width. At these legs 13, 14 close two short legs 15 u. 16, which only partially abut the respective side surfaces 6 and 4.
  • the short leg 16 of the frame 12 is bent outwards at its free end 17.
  • a handle, generally designated 18, is attached at 19. It projects beyond the plane of the frame 12 and rests with its back 20 in the illustrated embodiment of the narrow rectangular side surface 7.
  • notch 21 is formed which, in the position shown, engages under the folding triangle 9 of the carton 1, so that when it is received by the frame 12 it cannot slip down out of the frame 12.
  • Frame 12 and handle 18 can be punched out of a sheet metal plate in the embodiment according to FIGS. 1 to 3. They can consist of one piece.
  • the longer leg 13 of the frame 12 has a slot guide 22. This slot continues in the short frame leg 15 and continues to expand. About the slot guide 22 extends approximately at an angle of 45 ° a knife blade 23, which in the embodiment of FIG. 1 u. 2 has a rivet or screw fastening 24 on the leg 13.
  • the knife blade 23 can, however, also be fastened to a knife holder 25, which is shown in particular in FIGS. 8 is shown in a particularly advantageous embodiment.
  • the knife holder 25 is attached to the outside of the leg 13 having the slot guide 22.
  • the base plate 26 has an upper edge strip 27 and a lower edge strip 28, the overlap the upper edge 29 and the lower edge 30 of the leg 13.
  • Latching elements 31 molded onto the base plate 26 are intended for engagement in corresponding openings 32 of the leg 13.
  • the base plate 26 of the knife holder 25 is provided with a slot 33 which largely coincides with the slot guide 22 in the leg 13.
  • the knife blade 23 is provided with two bores 34 which are penetrated by corresponding pins 35 on the inside 36 of the base plate 26.
  • the lower end 37 of the knife blade 23 projects beyond the lower edge 38 of the base plate 26 of the knife holder 25.
  • a protective surface 40 molded onto the base plate 26, which protrudes beyond the contours of the blade end 37.
  • a protective cap 42 is molded onto the base plate 26 via a molded-on web 41, which can be inserted into the slot 39 between the blade end 37 and protective surface 40 of the knife holder 5 and has ribs 43 on its outer edge, which protectively enclose the blade end 37 in the inserted position.
  • Such a knife holder can be snapped onto the outside of the leg 13 of the frame 12 instead of the knife 23 fixedly attached in the embodiment according to FIG. 1.
  • the described embodiment of the knife holder is preferably suitable for production by injection molding from plastic.
  • Another embodiment of the knife holder is shown in FIG. 6 in connection with a frame 12 'made of plastic.
  • This knife holder 25 ' is made in one piece with the frame 12 and molded via a film hinge 44 to the upper edge 29 of the leg 13 of the frame 12'.
  • a catch 46 is attached, which has a counter catch 47 cooperates on the outside of the leg 13 when the knife holder 25 'is folded in the direction of arrow 67 on this frame leg 13.
  • the cheek 49 thus fulfills the function of the short frame leg 16 in the embodiment according to FIG. 1.
  • a hook 50 which is punched out and bent out of the leg in the sheet metal design, in the case of the plastic 6 and is used to tear one of the folding triangles 9 fixed to the folding box 1 out of its fastening and to raise it into the cutting position according to FIG. 2.
  • Fig. 9 shows a modified embodiment in that a further leg 51 is arranged on the frame 12 ', which lies in the use position on the upper end face 3 of the packaging carton and which has the slot guide 52 with the knife 53.
  • the knife blade 53 can of course be fastened with the aid of a knife holder 25.
  • the hook 54 of the leg 51 corresponds to the corresponding hook 50 of the embodiment according to FIG. 6.
  • the user grasps it on the handle 18 and first tears one of the folding triangles 9 out of the fixation with the aid of the hook 50 or 54 or 55 and bends it into the position according to FIG. 2. Then the tip 56 becomes this Folded triangle 9 inserted through the slot guide 22 and 52 and by Zie hen the device approximately in the direction of arrow 57, this tip 56 is cut off by the knife blade 23.
  • the packaging container 1 is thus open.
  • the frame 12 is now guided over the packaging box 1, for example from above.
  • the catch 21 slides on the back 20 of the handle along the parallelepiped side surface 7 to below the folding triangle 9 lying against this side surface.
  • the catch 21 By slightly lifting the frame 12, the catch 21 now engages under the folding triangle 9 in the region of its tip and thus locks the frame 12 against it Packing box 1 firmly. On the other hand, it is also possible to push the frame 12 from below over the packaging box or to insert it into the frame from above. Here, too, the two elements are brought together until the catch 21 engages with the corresponding triangular fold 9 of the carton 1.
