Definitions

  • the invention relates to bags with drawstrings.
  • Such bags are used in particular as garbage bags. They are often used in garbage containers to be filled with garbage. In many cases, the user places the upper edge of the bag outwards over the upper edge of the refuse container so that the refuse does not get between the bag and the refuse container. Nevertheless, it can happen that the edge of the bag is drawn into the refuse container and as a result the refuse falls between the bag and the refuse container.
  • a bag with a bag body which has an opening and along a peripheral region of the bag body in the region of the opening extending, elastic band having an elastically expansible, effective band length, which is shorter in the relaxed state is the peripheral portion, and which is secured to the periphery of the bag body leaving a balancing area such that the belt does not curl the bag body.
  • This bag can be attached elastically to the opening edge of a garbage container due to its elastic drawstring.
  • a bag with a bag body which has an opening and an elastic band extending along its peripheral area of the bag body in the region of the opening, which has an elastically expansible, effective strip length which is shorter in a relaxed state than the peripheral area, and the leaving a compensation area on Peripheral region of the bag body is fixed so that the tape does not curl the bag body.
  • the bag body is connected to the band in the compensation area via a connecting piece.
  • the invention has for its object to provide a bag that is better suited for uniform winding and has more favorable handling properties.
  • the bag according to the invention has a bag body with two sidewalls joined together along side seams, an opening between edges of sidewalls transverse to the side seams and seams extending from side seam to side seam at the same edges of the sidewalls, elastic drawstrings in the seams, joints of the seams with each other and with the elastic drawstrings at a distance from the side seams and tear lines in the seams, which bound the joints end regions of the seams.
  • the seams extend from side seam to side seam
  • a plurality of similar bags which are connected at the side seams to a bag chain, are continuously connected to each other in the area of the seams.
  • the seams are prevented from moving with respect to the bag chain.
  • the bags are easily wound without the bag top folds down and results in a non-uniform bag roll with a nasty wrap image.
  • the elastic band can be supplied in the form of a continuous elastic band material in the relaxed state. A separation of the elastic strip material is not required. The end regions of the seams can be separated from the remaining regions of the seams by tearing open the tear lines.
  • the opening in the relaxed state of the drawstrings has a smaller cross-section than the bag body below the opening.
  • the bag is fixed under elastic expansion of the drawstrings on the upper portion of a garbage container.
  • the drawstrings are stretchable in any direction. This facilitates the attachment or removal of the bag to or from a refuse container.
  • the pouch is easily closeable by pulling on one or both end portions of the seams at the opening, whereby the end portions can be knotted together to avoid accidental opening of the pouch.
  • the tear lines on a perpendicular to the hems and / or extending in the direction of the seams section.
  • At least one gripping recess is provided in the area of the seams, which makes it possible to grasp a drawstring from the outside. This facilitates the gripping of the bag for transport or pulling out of the drawstring for uniformly closing the opening.
  • connections of the seams with each other and / or with the elastic drawstrings are punctiform and / or flat.
  • the compounds are arrow-shaped. The arrows may indicate to the user which direction to pull on the drawstrings to sever the tear lines or to close the bag.
  • the distance of the connections from the side seams depends on the width of the bag body or the opening width and on the elasticity of the elastic drawstrings. According to one embodiment, the maximum distance of the connections from the side seams is about 1/10 to 2/10 of the length of the seams. As a result, the opening is limited only slightly by the connections, the limitation being overcome by elastic stretching of the drawstrings.
  • the connections and / or the side seams and / or the seam seams of the seams and / or a bottom seam of the bag body are welds between plastic materials.
  • the welds can be realized in the manufacture of the bags of plastic film materials simply by heat input.
  • the bag body has a bottom fold (rather than a bottom seam) so that it can be made to form a U by folding a single sheet of film. In this case, edge regions of the film web can be turned to the outside to produce the hems.
  • the recesses favor the production of the side seams by welding a plurality of plastic films.
  • the bag is in the area of Fill two additional layers of material to form the seams and two more layers of material because of the drawstrings.
  • layers of material of very different thickness along the side seams are avoided by the recesses in the area of the seams, so that they can be welded faster and more uniformly.
  • the force required for the separation of the bags of a bag chain is reduced by the recesses.
  • the recesses extend approximately over the entire height of the elastic drawstrings, ie the extension of the elastic drawstrings in the direction of the side seams. Outside the drawstrings, the seams preferably have no recess. As a result, one of the course of the side seams over the elastic drawstrings is avoided, which is particularly advantageous in view of the aforementioned effects.
  • the bag has seam seams ending at a distance from the side seams.
  • the bag body below the opening has a constriction of the cross section.
  • the constriction prevents garbage from rising along the side seams and escaping in the region of the tear lines when the opening is substantially closed by means of the drawstrings. It is formed for example by straight, curved or planar connections of the two side walls.
  • the constriction is formed by welds of the side walls extending transversely to the side seams.
  • the elastic drawstrings made of elastic plastic and / or rubber.
  • the bag body consists of plastic films.
  • the bag body and the elastic drawstrings have different colors to facilitate the user's use of the bag.
  • a bag chain according to the invention comprises a plurality of bags according to the invention, which are connected to each other along side seams.
  • a dividing line running parallel to the side seams is present in the connecting region between the side seams of adjacent bags.
  • the dividing line facilitates the separation of adjacent bags from each other.
  • the dividing line is a perforation line.
  • the drawstrings extend over the entire length of the bag chain and are interrupted by the dividing lines.
  • the bag 1 has a bag body 2 of two superimposed side walls 3, 4, each having a folded-over seam 5, 6 above.
  • the side walls 3, 4 are laterally interconnected by side seams 7, 8, which are directed transversely to the seams 5, 6.
  • the bag body 2 has a bottom fold 9 connecting the side walls 3, 4, which is arranged parallel to the seams 5, 6 at the opposite end of the bag body 2.
  • the seams 5, 6 are connected by seam seams 10, 11 with the side walls 3, 4, which extend parallel to the bottom fold 9.
  • the bag body 2 has an opening 12.
  • an elastic drawstring 13, 14 are arranged in each case.
  • the elastic drawstrings 13, 14 have in end regions 15, 16 of the seams 5, 6 connections 17, 18 with the seams 5, 6.
  • the compounds 17, 18 also connect the seams 5, 6 with each other.
  • the end portions 15, 16 are bounded by lines of perforations 19, 20, 21, 22 formed by perforation lines which run parallel to the seams 5, 6 from the side seams 7, 8 and at a distance from the side seams 7, 8 across the seams 5, 6 are extended to the upper edge of the opening 12.
  • Both seams 5. 6 have grip recesses 23, 24, through which the drawstrings 13, 14 are accessible from the outside.
  • FIG. 1 Several bags 1 of the type described above are shown in FIG. 1 adjacent to their side seams 7, 8 connected to a bag chain together. Between the side seams 7, 8 of adjacent bags 1 dividing lines 27 formed by perforation lines for separating the bag 1 from each other are present.
  • the end regions 15, 16 of the seams 5, 6 of adjacent bags 1 of the bag chain have recesses 28, 29 which interrupt the side seams 7, 8.
  • the bag chain is easily seamed by folding and folding two plastic film webs for the sidewalls 3, 4 and connecting regions of adjacent bags, applying elastic drawstrings, folding edge portions of the two plastic film webs around the drawstrings, forming the side seams 7, 8, the seam seams 10, 11, if necessary, the bottom seams 9, the compounds 17, 18 and the side bars 25, 26 produced by welding.
  • the tearing lines 19, 20, 21, 22, handle recesses 23, 24, recesses 28, 29 and dividing lines 27 are produced by punching and perforating.
  • the elastic drawstrings 13, 14 can be stretched in order to fix or remove the upper edge region of a bag 1 at the edge of a refuse container.
  • the seams 5, 6 are drawn in Fig. 3 crimped to illustrate that they can take on the edge of the refuse container a corresponding shape.
  • the side bars 25, 26 prevent a filling of the bag 1 at the side seams 7, 8 emerges near the side, where the end portions 15, 16 have been released from the hems 5, 6.
