Definitions

  • the invention relates to a method for producing a sack or bag with a rectangular bottom when filled and with a handle part and sacks or bags produced by this method.
  • Sacks or bags of this type are known for example from DE-GM 81 15 909 and 82 07 889.
  • these known sacks or bags have the disadvantage that the leg-like strips which form a base sheet and which are connected in their central region to the web part provided with the grip hole are glued to the floor over the full or almost the entire area, so that on the floor or the web part, that is to say in the region of the longitudinal central plane of the sack penetrating the bottom, considerable stresses are exerted when carrying, which result from the fact that the forces exerted by the web part essentially have a central area be introduced with these through the line running through the floor rectangle.
  • German patent application 40 12 896.2 which is formed by corner inserts partially overlapping side inserts and whose handle part consists of a central web part with the grip hole and side leg-like parts connected to it
  • the strip is made of flexible material, with the drawn-up bottom being glued or welded in a manner known per se to an inner bar which is sealingly connected to the inner edges of the corner inserts and at least the inner edges of the side inserts adjacent to their fold lines , wherein the handle part is inserted into the still open floor and its leg-like strips are at least partially covered by the side folds and glued or welded to them.
  • this sack or bag In this sack or bag, the side of the side leg-like strip of the part facing the inner bar formed by a slip, which carries the web part provided with the grip hole between them, is not glued to this inner bar, but the side folds overlap the side leg-like strips and are with this glued or welded through the sides, on which there is also the middle web part with the handle part.
  • This sack or bag is therefore characterized by a tunnel, which is formed between the underside of the handle part and the outside of the inner bolt.
  • the load-bearing capacities are introduced essentially directly into the side walls of the filled sack or bag via the central web part and the leg-like strips connected to it, so that the handle part is able to take up substantially larger load-bearing capacities without the sack thereby is damaged or parts of the floor are detached from it.
  • the object of the present invention is therefore to provide a method for producing a generic sack or bag, by means of which this can be easily and inexpensively produced by machine in a production line.
  • Sacks or bags which are produced by one of the above processes are particularly advantageous if they are made from a material, preferably paper.
  • the bags or sacks are characterized by their good recyclability.
  • the sacks or bags produced according to the invention consist of paper, it should be emphasized, however, that within the scope of the invention they can also consist of any other material, in particular also of plastic.
  • plastic bags or sacks are not necessarily glued in the context of the invention, but, as is part of the prior art, can also be welded.
  • FIG. 11 illustrate a first exemplary embodiment of the method according to the invention for producing a paper diaper bag with a block bottom. It is assumed 1 of a tube piece 60 with side folds 62, in which pre-grooves 64 and 66 are provided, which run parallel to one another and perpendicular to the side folds 62. The piece of tubing prepared in this way is drawn around the notch 66 as shown in FIG. 2. A floor cover sheet 70 is glued onto this floor which has been pulled up in this way. The design of the bottom cover sheet 70 results in detail from the detailed illustration of the bottom cover sheet of FIGS. 4 to 6. FIG. 4 shows the back of the bottom cover sheet, which is placed on the open floor.
  • a size gluing 78 is shown, by means of which the bottom cover sheet 70 is glued to the corner inserts 68 and the edge areas of the open floor up to the pre-grooved lines 64. 3 that the rectangular bottom cover sheet 70 protrudes on two sides beyond the opened bottom of the bag.
  • a bow-shaped cardboard reinforcement 74 is glued to one side of the protruding area of the bottom cover sheet 70.
  • a U-shaped sheet 72 is glued onto the bottom cover sheet 70 over the entire width of the bottom cover sheet 70, as can be seen from FIG. 6.
  • an additional cardboard strip 76 is glued on at a point at which the finger hole punching is to be provided later.
  • format gluing 80 is applied to an edge of the glued-on slip 70, the free leg of the U-shaped sheet 72 being included in the format gluing.
  • the corresponding format-glued area is designated by 80 in FIG. 8, the lower bottom half is folded over the inner fold line 66 onto the upper bottom half.
  • 9 is a grip hole 82 below the reinforcement 74 and in the area of Reinforcement 76 stamped. When the handle hole is punched, the longitudinal line 83 facing the edge is not cut through, but only pre-grooved.
  • FIG. 10 shows a detailed side view of the attachment area of the handle part, from which it is clear that a tunnel-shaped base was again formed.
  • FIGS. 11a and b show the meaning of the reinforcements 74 and 76 in the region of the finger hole punching 82.
  • the bow-shaped cardboard reinforcement 74 in particular due to its bow-shaped shape, tears off the edge of the bag, which preferably consists of paper, in particular by preventing the forces from the ends of the reinforcement facing away from the edge are advantageously distributed, the reinforcement 76 extends beyond the folded edge 83 of the finger hole tabs and causes a thickening in the region of the open finger hole, as can be seen in FIG. 11b, which makes it more comfortable to wear improved that an unpleasant cutting of the grip hole edge into the palm is prevented.
  • FIGS. 12-20 The method according to a second embodiment of the present invention is explained with reference to FIGS. 12-20.
  • This in turn is an economical process for the continuous production of diaper articles.
  • two incisions 92 and 94 which are arranged perpendicular to the side edges and are arranged on the extension of a line, are spaced apart in a continuously advanced flat web 90.
  • Two cuts 96, 98 and 100, 102 which are parallel to each other, are aligned perpendicular to these cuts.
  • Flat track 90 is glued in strips on one side edge.
  • grip parts 106 and 108 are glued to the web in the area of the incisions.
  • the ends 110 and 112 of the handle part 106 and 114 of the handle part 108 are glued parallel to the incisions 96 and 98 or 100 and 102.
  • the ends are each glued to the entire surface of the flat web 90.
  • the connecting part between the ends is approximately parallel to the incisions 92 and 94 and thus protrudes beyond the incisions 96 and 98 or 100 and 102.
  • the flat sheet 90 is cut accordingly and folded into a piece of hose 90 'with side folds 118 in such a way that the grip parts lie one above the other. Cutting the flat web is possible in particular in the areas of the handle parts 106 and 108 in that incisions 92 and 94 were made before the handle parts were glued on (see FIG. 12 here).
  • FIGS. 14a and 14 show the hose section 90 'immediately after the hose section has been formed.
  • 14a shows a view in which the tube piece has been slightly pulled apart from the lower opening.
  • three pre-grooved fold lines 120, 122 and 124 running perpendicular to the side edges are formed at the end of the tube piece 90 'to which the handle parts 108 and 106 are glued.
  • the fold line 120 located closest to the end abuts approximately at the incisions 96 and 98.
  • FIG. 16 shows the bottom drawn around the fold line 124.
  • a cover sheet 126 which is glued on the edge side, is placed on this and thereby glued on.
  • the folded edge 128 is not glued, the fold edge of which lies approximately above the fold line 120.
  • the folded edge 128 and a flat area 130 above the folded edge 120 are size-glued. 19
  • the bottom is folded over the fold line 124 and glued in the area of the format gluing of the surfaces 130 and 128.
  • the diaper bag prepared in this way is then again filled from below and then closed in the lower, still open area in a manner known per se, which results in the container shown in FIG. 20, which advantageously has a tunnel floor, which is particularly useful when force is applied the force introduced by the handle 106, 108 is advantageous.

Abstract

La présente invention se rapporte à un procédé pour la fabrication d'un sac ou sachet comportant un fond rectangulaire a l'état rempli et une partie servant de poignée, ainsi qu'à des sacs ou sachets fabriqués selon ce procédé. Pour résoudre la tâche consistant à simplifier des procédés déjà connus, deux lignes de pliage prérainurées parallèlement (64, 66) et perpendiculaires aux arêtes latérales sont formées à une extrémité d'une pièce tubulaire comportant des soufflets (62). Ensuite, le fond est tiré vers le haut formant des arêtes de coin (68). Une feuille de couverture de fond rectangulaire (70), sur laquelle sont collés une feuille pliée en U et des renforcements (74, 76), est collée dessus. Après application de la colle conférant une stabilité dimensionnelle (80), la moitié inférieure du fond est repliée vers le haut sur la moitié supérieure du fond, en suivant la ligne de pliage intérieure. Finalement, le trou de poignée est découpé au-dessous et dans la région du renforcement.
