Definitions

  • the invention relates to a sack or bag with a rectangular bottom when filled, which is formed by corner inserts partially overlapping side inserts, and with a glued or welded handle, which consists of a central web part with the grip hole and connected to this side leg-like strips of flexible Material exists.
  • 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 over the entire surface or almost over the entire surface to the floor
  • On the web part, i.e. in the area of the longitudinal center plane of the sack passing through the floor considerable stresses are exerted when carrying, which result from the fact that the forces exerted by the web part are introduced into the latter essentially in the area of a line running centrally through the floor rectangle.
  • the object of the invention is therefore to provide a sack or sack of the type specified at the outset, in which the base itself is largely relieved of the load-bearing forces which are introduced via the web part having the grip hole.
  • this object is achieved in a sack or bag of the generic type in that the opened bottom is adhesively bonded or welded in a manner known per se to an inner bar which seals the inner edges of the corner folds and at least the inner edges of the side folds adjacent to the latter Folded lines are connected, that the grip part is inserted into the still open floor and that its leg-like strips are at least partially covered by the side folds and glued or welded to them.
  • the side of the side leg-like strips of the handle part which face the inner bar formed by a slip, and which carry the web part provided with the grip hole in the middle between them, is not glued to this inner bar, but the side folds overlap the side leg-like strips and are glued or welded to these on their sides, on which the middle web part with the grip hole is also located.
  • the sack or pouch according to the invention 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 via the central web part and the leg-like strips connected to it, so that the handle part is able to absorb significantly larger load-bearing capacities without the sack being damaged or the floor parts being detached therefrom .
  • corner folds are expediently formed at least over part of their width by mutually parallel incisions in the flat-lying tube piece which forms the workpiece for producing the sack or bag.
  • one side turn is shorter than the other, so that corresponding holding strips result at the opening edges opposite the bottom edges of bag workpieces separated from a tube sheet.
  • the handle consists of a blank that is folded onto itself, from the middle part of which forms the web part, the leg-like strips are separated by fold lines.
  • the leg-like strips can be folded back over at least part of their length.
  • the parts can also be folded back so far that they overlap one another.
  • a reinforcement label that at least partially covers both can be attached to the underside of the leg-like strips of the handle part.
  • the tube piece 1 shows a piece of hose 1 separated from a tube of paper or thermoplastic, which forms the starting workpiece for the manufacture of the sack.
  • the tube piece 1 is provided on its upper edge with two cuts 2 parallel to each other and to the lateral fold edges, which are approximately the same distance from the lateral fold edges 3. While the cutting edge between the side incisions 2 of the upper wall is aligned with the side parts, the lower cutting edge 4 between the side incisions 2 is offset inwards by the amount a, so that there is a corresponding edge strip on the opposite lower side wall of the bag workpiece.
  • FIG. 2 shows the sack workpiece according to FIG.
  • the corner folds 5 and the side folds 6, 7 result from the pulling up, the side fold 6 being narrower than the side fold 7 by the width of the edge strip 8.
  • the side folds 6, 7 are partially separated from the corner folds 5 by the cutting lines 2.
  • the side folds 6, 7 are folded around the pre-grooved lines 9, 10.
  • the rectangular inner bar 12 which covers the inner parts 13 of the corner folds 5 and the parts of the side folds 6.7 adjoining the grooved fold lines 9, 10 is then placed on the so-called bottom square according to FIG.
  • the inner bar 12 is glued all around with the parts 13 of the corner folds and the inner areas of the side folds 6,7 welded so that it seals the bottom.
  • the handle is then placed on the still open floor prepared in this way, namely the lateral leg-like strips 16, 17 adjoining the central web part 15 via lower fold lines, which together form a rectangular sheet which forms the inner bar 12 in the area of the corner folds 5 around edge strips covered with the width b.
  • the inner bar 12 is placed in the form of a rectangular slip on the open and flat floor and glued to it in the manner described.
  • the inner bar 12 covers the inner edges of the side folds 6, 7.
  • the inner bar 12 covers the inner parts 13 of the corner folds, of which plan views of the edges are visible in FIGS. 5 and 6.
  • the side envelopes 6, 7 with the glued-on inner bars 12 are folded around the fold lines 9, 10 on the outer sides of the leg-like strips 16, 17 of the handle part on both sides of the central web part 15 and glued to these. 8, the narrower side turn 6 extends approximately up to the central web part 15 of the handle part, while the wider side turn 7 extends over part of the central web part 15.
  • the lateral strips 16, 17 are made wider and folded over on themselves in such a way that they overlap one another in the region of the web part 15.
  • FIG. 14 shows an embodiment similar to that according to FIG. 12. Here, however, the adhesive seam is offset.
  • the lower region of the grip piece forms the inner bolt, the tunnel being formed between the reinforcement label 21 and the lower region. In these embodiments, it is therefore unnecessary to use an inner bolt.
  • FIG. 13 shows an embodiment in which the leg-like strips are folded back on themselves over at least part of their length.
  • Fig. 9 the bag provided with the handle can be seen in the filled state.
  • the side folds 6, 7 are folded onto the side leg-like strips of the handle and glued to it. This results in a flat tunnel-like passage 25 between the underside of the leg-like strips 16, 17 and the inner bolt 12, which is caused by the fact that the parts adjoining the central web part 15 form, as it were, pull tabs which carry the load-bearing forces into the side walls of the filled bag initiate.
  • leg-like strips is expediently not welded or glued to the tucked-in and overlapping parts, so that the tunnel-like formation can still occur, which leads to the favorable introduction of the load-bearing forces into the side walls.
