Definitions

  • the invention relates to mailing bags, pouches or the like. made of paper and the like and a method for their production, wherein the mailing bags, bags or the like. each consist of a front part and a back part, of side parts and a bottom, and each have a closure part and a closure flap.
  • Mailers and pouches of the type mentioned and methods for their production are known. There are mailing bags and pouches with or without side gussets and with side or middle adhesive. The floor can also be foldable for folding.
  • the invention is based on the problem of designing mailing bags or bags made of paper and the like, which essentially have the shape and shape of envelopes, in such a way that they are largely stable in the open state and practically do not buckle.
  • the invention provides that the side parts can be folded onto the back part.
  • the side parts are rigid in themselves and have no gussets themselves. In order to be able to fold the mailing bag, the bag or the envelope in view of its possibly wide side parts, the side parts are folded over onto the back part. In the open state, the essentially rigid side parts stabilize the entire mailing bag and give it the greatest possible hold.
  • the side parts are preferably double-layered.
  • the production of mailers, bags, envelopes or the like according to the invention. is preferably carried out in such a way that they are closed in the region of their side parts with the aid of two side flaps which form them, are placed one on top of the other and are glued to one another (front part and back part side flaps).
  • the individual steps here are similar to the block bottom manufacture of mailing bags etc., with the difference that the bottom is not closed like block bottom, but that the side parts or the narrow sides are folded like block bottom, glued and then closed.
  • Figure 1 which is basically referred to below as a mailing bag, consists of a front part 2 and a back part 3, side parts 4 and 5 and a bottom 6 and has a closure part 7 and a closure flap 8.
  • a closure part 7 is not only located on the front part 2, but also a closure part 9 is provided on the back part 3 in the region of the pocket opening 10.
  • tab-like, lateral closure pieces 11, 12 are arranged at the upper, pocket-opening end of the side parts 4, 5 and can be folded over the pocket opening 10.
  • the side parts 4, 5 are flat and stiff. They have no fold line.
  • the side parts 4, 5 can be folded onto the back part 3.
  • the two protrusions 14 and 15 in the back part 3 extend only up to the middle transverse transverse protrusion 19.
  • the shape and shape of the folded mailing bag 1 can be seen in FIG. 12, which also shows the state at the end of the last step in the manufacturing process. However, FIG. 12 shows a mailing bag 1 without a closure part 9 on the back part 3.
  • the processing of the blank 23 according to FIG. 4 goes shows that front part side flaps 24, 25 are located laterally outside on the front part 2 and back part side flaps 26, 27 on the back part 3. Furthermore, locking tabs 28, 29 and 30, 31 are arranged on them, the locking tabs 28 and 30 or 29 and 31 coming together in the manufacturing steps as well as the front part side flaps 24 and 25 on the back part side flaps 26 and 27.
  • the side parts 4, 5 and the side closure pieces 11, 12 are therefore double-layered and thus extremely rigid.
  • bottom side flaps 32, 33 taper asymmetrically towards their free end 34. This is due to a lateral recess 35, which is expedient from a manufacturing point of view.
  • Another recess 36 is located at the bottom end of each front part side flap 24, 25. It is also expedient in terms of production technology.
  • the recesses 35 and 36 complement each other in their effect and face each other.
  • transverse projections 37, 38 and 39 are provided in a manner known per se and serve to form the closure part 7, the closure flap 8 and the closure part 9.
  • the closure part 9 and the closure tabs 30, 31 can in principle also be missing. Furthermore, instead of the locking tabs 28, 29, quarter-circular locking pieces can also be used 5, are provided with a radially directed protrusion 42 and are connected to both the front part side flaps 24, 25 and the closure part 7 according to the exemplary embodiment shown in FIG. This creates a mailing bag 1a according to FIG. 2. Otherwise, the mailing bag 1a corresponds to the mailing bag 1.
  • FIGS. 2, 4 and 5 also indicate that perforation lines 43 may also be provided. This applies in particular in the area of the parts used to close the pocket opening 10. They can be removed if necessary through the perforation lines 43 and then result in a versatile protective cover 44 according to FIG. 3.
  • step B a separation step 52 and a pull-out of the blank 23, 23a take place, ie a distance is created between this and the end of the web 51.
  • step C the desired flaps and tabs cut out, ie for the mailing bag 1, the front part side flaps 24, 25 and the back part side flaps 26, 27, the bottom side flaps 32, 33 and the closure part 9 as well as the closure part 7 and the closure flap 8 and the side closure flaps 28 to 30 with Generated using side cuts.
  • the steps illustrated in FIGS. 6 and 7 relate specifically to the production of the mailing bag 1a, which has no closure part 9 and other types of closure pieces 40 and 41, ie quarter-circle shaped.
  • the back part 3 with the parts located on it is folded over onto the front part 2 around the central floor transverse protrusion 19 (method step D).
  • the front part and back part side flaps 24 to 27 are folded laterally from the outside inwards around the pre-breaks 14 to 17 and the bottom side flaps 32, 33 are folded in, as can also be seen from a comparison of FIGS. 9 and 10.
  • the front part side flaps fold over the longitudinal protrusions 16 and 17 and the back part side flaps 26, 27 about the protrusions 14 and 15 in the back part 3.
  • the bottom side flaps 32, 33 also lie on the front part side flaps 24 and 25.
  • back part side flaps 26, 27 are provided with a glue trace 52a in accordance with method step F and finally the side parts 4, 5 are closed by folding back the back part side flaps 26, 27 around their longitudinal protrusions 16, 17 in the back part 3.
  • the back part side flaps 26, 27 lie on the front part side flaps 24, 25.
  • method steps A to G take place in such a way that method step A into the method steps A 'and A''is divided and that process step B takes place between the two process steps A' and A ''.
  • a ' only the longitudinal breaks 16 and 17 for the front part and back part side flaps 24 to 27 are initially generated. All other pre-cuts, ie the cross-cuts and the angle cuts as well as the two cuts 14 and 15 for the back fold lines, are only introduced after the separating cut 52 according to method step B in a further method step A ′′ (FIG. 7).
  • the side parts 4, 5 are produced in a manner which is somewhat close to the block bottom production. However, while only one opening is closed in the block bottom, two opposite openings or sides of the mailing envelope are closed in accordance with the described production method, and the steps used do not correspond identically to the steps known from block bottom production.
  • the bottom side flaps 32, 33 lie between the front part side flap 24 and 25 and the back part side flap 26 and 27, as is also shown in FIGS. 10 and 11. Since the front part side flaps 24 and 25 come to lie on the inside and the back part side flaps 26, 27 are folded back onto the front part side flaps on the outside in method step G according to FIG. 12, it is also sensible to use inner side flaps 24, 25 and outer ones To speak of side flaps 26, 27 instead of front part side flaps 24, 25 and back part side flaps 26, 27.
  • the two back part side flaps 26, 27 fold around the fold lines or pre-creases 14 and 15.
  • the back part or outer side flaps 26, 27 simultaneously pivot the bottom side flaps when folding from the position according to FIG. 9 into the folded-back position according to FIG 32, 33 through 90 ° from a laterally outward position into a position towards the pocket opening 10. As a result, they are mitred. This is achieved with the help of the angle breaks 21, 22.
  • the back part side flaps 26, 27 pull the bottom side flaps 32, 33 over the front part side flaps 24, 25, which according to FIG. 10 on an edge strip 45 (see also FIG. 5) on the inside of the front part 2 and on a strip-shaped part 46 (FIG. 5) rest, which are located in the area of the back part 3 in each case between the breaks 14 and 15 on the one hand and the longitudinal breaks 16 and 17 on the other.
  • the arrangement of the creases 14 and 15 and the longitudinal creases 16 and 17 and the dimensions of the side flaps 24 to 27 are chosen so that the outer or back part side flaps 26 and 27 after gluing (process step F in Figure 11) when folding around their Place longitudinal breaks 16 and 17 (method step G in FIG. 12) with simultaneous closing of the side parts 4, 5 exactly on the front part side flaps 24, 25 and the bottom side flaps 32, 33.
  • the mailing bags 1, 1a are produced during a continuous longitudinal conveyance in accordance with the arrows in FIGS. 6 to 12.
  • the bottom-side end 53 (FIG. 9) for the mailing bag 1, 1a is during formation and transported forward in the direction of transport when closing the side parts 4, 5.
  • back part side flaps 26, 27 it is also possible for the back part side flaps 26, 27 to be set back from the position shown in FIG. 9 to a position not shown when the side parts 4, 5 are formed, with a zigzag fold.
  • the two advantage side flaps 24 and 25 then remain spread out in such a method step D ', not shown.
  • Both the mailing bag 1 and 1a as well as the manufacturing process can be modified in many different ways.
  • the front part and back part side flaps 24 to 27 can not only be folded together as part of process step E, but it is also possible to first fold back only the back part side flaps 26, 27 together with the bottom side flaps 32, 33 and then in a next step, the front part side flaps 24, 25 fold.
  • the glueing is then carried out according to method step F and finally the back part side flaps 26, 27 are folded back onto the front part side flaps 24, 25 and the bottom side flaps 32, 33 for closing the side parts 4, 5.
  • Another variant of the method is the above-mentioned zigzag folding of the back part side flaps 26, 27.
  • the side flaps are then glued, whereupon the front part side flaps 24, 25 are folded over onto the back part side flaps 26, 27.
  • the recesses 35 and 36 in the bottom side flaps 32, 33 and in the front side flaps 24, 25 facilitate flipping the flaps 24, 25 and 32 and 33 during the folding process. These flaps can therefore be moved past one another almost without contact.
  • the front part and back part side flaps 24 to 27 can be glued in the area of the bottom side flaps 32, 33 if there are recesses 35, 36.
  • the bottom side flaps 32, 33 can finally be completely missing.
  • a strap-free variant is available e.g. when using the mailing bag as an organization bag.
  • the bottom part forming the bottom 6 is integrally connected to the front part 2 along the bottom transverse protrusion 18 and integrally to the back part 3 along the bottom transverse protrusion 20.
  • the bottom 6 is also rectangular and consists of a single layer of material in the finished product.
