Definitions

  • the invention relates to a method for producing at least one stack formed from bags according to claim 1, a stack formed from bags according to claim 7,
  • bags in particular plastic bags (such as waste bags, freezer bags or the like), and to wind them up coherently on a roll. A predetermined number of such bags are then on a roll. A user then separates the bags one after the other as required so that they can be used for their intended purpose. This separation occurs, for example, in that the bags that were previously connected to one another on the roll via a perforation or welding are torn off by the user along this perforation.
  • a dispenser for plastic film bags from the roll which consists of a tubular film, preferably provided with folds on its two long sides, which has transverse tear-off perforations with at least a partial average and in the vicinity of the same, in the pull-off direction in front of these, also transverse welded bags - Has bottom seams
  • the dispenser having the shape of an approximately cylindrical sleeve with a removal slot for the tubular film running in its longitudinal direction, with the edge of the removal slot overflowing from the tubular film when it is pulled out of the sleeve in the area of each partial cut in the tear-off perforation of the tubular film is one that protrudes beyond this edge in the circumferential direction of the sleeve, that is, protrudes into the removal slot or almost completely bridging tongue is provided which is approximately rectangular in its basic shape, the width of which in the longitudinal direction of the sleeve is equal to or only slightly smaller than the width of the associated partial average in the
  • A1 relates to a method for producing stacks of folded bags from a tubular or semi-tubular web which is provided with transverse welds to form the bags and from which the subsequently stacked bags are separated. D1 thus discloses the preamble of claim 1.
  • the invention is therefore based on the object of providing a method for producing at least one stack formed from bags, a stack formed from bags.
  • the method listed above enables the continuous production of individual bags to form at least one folded stack that has an angular geometry (for example cuboid shape).
  • angular geometry for example cuboid shape
  • These stacks are suitable for inclusion in a container, for example a dispenser box.
  • the container also has an angular geometry, which in the interior area approximately corresponds to the geometry of the at least one stack to be accommodated there.
  • the user can remove each bag individually from the stack with little effort.
  • the bags can also no longer be damaged or even destroyed when separated by the user.
  • Each bag is made available to the user in consistent quality.
  • the combination of the formatting fold of the respective bag with the folding of the stack ensures that after a bag has been removed from the stack, another bag is always made available for removal from the stack and a compact stack is realized that optimally uses the space within the container exploited.
  • containers such as dispenser boxes can be stored very well (by making optimal use of the available storage space) and presented attractively for sale (since, compared to rolls, large areas of the angular container are available for information for consumers and/or product information) .
  • the user can also be provided with closures to securely close the bags.
  • a continuous process is therefore provided from the production of the bags to the formation of stacks.
  • Packaging i.e. collecting individual bags to form an overall package or stack, takes place for a variable but defined number of bags.
  • the layered web is formed from at least two layers of material.
  • the process can be carried out continuously if, for example, web-shaped, semi-tubular or tubular material is continuously produced by extrusion.
  • the process can be carried out batchwise or discontinuously if the web, semi-tubular or tubular material is made available, for example, on rolls. It is also conceivable to combine the materials supplied on rolls with the material of the next roll before one roll is used up in order to obtain a quasi-continuous process.
  • Batch processes are processes that are processed as a 'batch', i.e. strictly one after the other. Therefore, batch processes are also known as batch processing.
  • material on rolls is fed into the process one after the other.
  • the batch process or batch process or set operation is a discontinuous production process. A limited amount of material, for example a roll, is fed into the process as a whole and removed from it as a whole after the production process has been completed, in this process, for example, as a stack formed from bags.
  • a fold can be hard in the sense of a fold or with a curve. Any configuration of folding between these extremes is also possible.
  • a fold is created in the process by means that cause the direction of the material to reverse. At least one fold, for example to form a material tube or material half-tube, can also have been introduced into the material before the process.
  • Semi-tubular material refers to material that has undergone a reversal of direction to form a lower and an upper layer of material. This reversal of direction can also be viewed as a folding.
  • Semi-tubular material can be fed to the process or produced in situ from web-shaped material in the process.
  • Semi-tubular material can also be made by forming a cohesive seam in the longitudinal direction from two layers of web-shaped material before being fed to the method according to the invention or during the implementation of the The method according to the invention can be generated.
  • the cohesive seam is created, for example, by gluing or welding.
  • Tubular material is material that is self-contained and is produced, for example, by extrusion or has a longitudinal connection point. This connection point can be made cohesively, for example by gluing or welding. If tubular material is exposed to pressure between two flat surfaces, a lower layer of material and an upper layer of material are formed. In the transition area between these two material layers, the material undergoes a reversal of direction, which can also be seen as a fold.
  • the stack is provided with a safety device to prevent the stack from accidentally falling apart.
  • This securing can be done, for example, by a flexible, flexible element such as a wire, a band or the like. Securing can also be done by surrounding the stack with shrink wrap. Alternatively, securing can be done by wrapping the stack with paper, for example in the form of a band. Safety measures such as adding more mass to the stack are also covered by the idea of safety.
  • the individual bags of a stack can also be provided with adhesive points in order to attach the individual bags of the stack to one another, whereby this security should be designed to be easily overcome for use of the individual bags.
  • the security can also secure the transport of the stacks, for example from the production of the stacks to the packaging of the stacks. This ensures that the arrangement of the bags within the stack does not change during transport.
  • the stacks provided with security can also be stored in order to receive outer packaging later or to leave the storage location without further packaging measures.
  • the stacks provided with the security described above can be supplied for storage or transport as well as for sale, although it is alternatively also conceivable to supply the stacks provided with the security in this way to the container. However, it should be taken into account that the backup may have to be removed if individual bags are to be removed from the container and thus from the stack.
  • the stack is transferred to a dispenser box.
  • the previously listed process allows for the continuous manufacture of individual bags and the collection of bags to form a stack for inclusion in a dispenser box.
  • the formatting folding of the individual bags and the subsequent folding for example carried out as a Z-fold or U-fold, to form the stack makes it possible to remove each individual bag from the removal opening of the dispenser box.
  • the user can remove each bag individually from the dispenser box with little effort.
  • the bags can also no longer be damaged or even destroyed when separated by the user.
  • Each bag is made available to the user in consistent quality.
  • the combination of the formatting fold with a further fold for example the Z or U fold, advantageously ensures that after a bag has been removed, another bag is always made available for removal.
  • the user can also be provided with closures to securely close the bags.
  • a continuous process is provided from the production of the bags to their packaging in dispenser boxes.
  • the stacks that have been secured can also be transferred to a dispenser box. This makes the stacks easier to handle and prevents the stacks from falling apart before they get into the dispenser box.
  • the security can then be removed immediately after the stacks have been transferred to the dispenser box or can be removed the first time the user accesses the contents of the dispenser box. This ensures that the stacks do not change shape during transport.
  • the weld seam is carried out with exact repeatability based on markings.
  • the precise execution of at least one weld seam enables bags with identical or almost identical dimensions.
  • the user thus receives bags of the same volume.
  • the markings for example one marking or several markings per bag, can also help the user to always achieve the same fill levels in the bags. If the material fed into the process has regular imprints, it is ensured that each bag is provided with the appropriate imprint.
  • the at least one fold introduced into the stack is carried out as a Z-fold, a W-fold, an accordion-like fold or a U-fold.
  • the at least one fold of the stack which already has a formatting fold for each bag, is characterized by a change in direction of the entire bag forming the stack.
  • a U-fold results in one such change in direction
  • a Z-fold results in two such changes in direction.
  • More than two changes of direction (folds) are also conceivable, for example a W-fold or an accordion-shaped sequence of folds.
  • a dispenser box can also hold one or more stacks folded in this way. These stacks can, for example, be aligned parallel to one another, transversely to one another or alternatively parallel and transversely to one another. The formation of various angles between the individual stacks is also conceivable.
  • the formatting fold is introduced into the layer web in such a way that the width of the layer web after the formatting fold has been introduced corresponds at least to the inner dimension of an edge length of the dispenser box. This means that a measurement of the dispenser box is transferred to the bag as part of the process. This ensures that the stack formed from these bags can be inserted into the dispenser box.
  • the size can be varied according to the dispenser box used.
  • a bag having a lower material layer and an upper material layer connected by at least one weld seam, the bag having at least one opening arranged at right angles or almost at right angles to the at least one weld seam. If the bags are arranged at right angles or almost at right angles to the weld seam and have at least one opening, this opening is opposite a fold.
  • a bag which has a lower material layer and an upper material layer, connected by at least one weld seam, the bag having at least one fold arranged at right angles or almost at right angles to the at least one weld seam.
  • the at least one fold arranged at right angles or almost at right angles to the weld seam can be opposite another fold or an opening. If there is an opening opposite the at least one fold, the web of material fed to the process consists of a half-tube. If the at least one fold is opposite another fold, the web of material fed to the process consists of a tube.
  • the at least one weld seam forms a bottom seam or a side seam of the separated bag. If the weld seam forms a bottom seam, the web was fed into the process as a hose. If the web of material is supplied as a half-tube, the at least one weld seam forms a side seam of the later bag.
  • the at least one weld seam forms a bottom seam of the bag, an opening is formed opposite it.
  • the web was fed into the process as a tube.
  • a separating cut or a separating weld is carried out opposite the weld seam, which runs transversely to the processing direction of the material web, at a distance corresponding to an edge length of the bag, so that the bag resulting from a tubular web of material has only one weld seam.
  • he has two Folds made at right angles or almost at right angles to this weld seam. This design enables the production of a bag with just one weld.
  • the bag is formed as a bottom seam bag with a weld seam.
  • the web is fed into the process as a hose.
  • Just one weld seam is enough to create a bag that is closed on three sides.
  • An opening is provided for filling the bag.
  • the bag After the bag has been filled, it can be closed materially, for example by welding.
  • a rubber band or a clip is also conceivable.
  • the invention provides that the bag is formed as a side seam bag with two weld seams.
  • a half-tube is fed into the process as a web of material.
  • the bag which is closed on three sides after going through the process, has a bottom created by folding and two weld seams arranged at right angles or almost at right angles to the bottom as sides.
  • An opening that has already been created by folding the web into a half-tube remains.
  • the bag designed as a side seam bag, can be filled through this opening. After the bag has been filled, this bag can also be closed materially, for example by welding. A rubber band or a clip is also conceivable.
  • the bag has at least one marking for precise processing.
  • markings enable work steps to be carried out at always the same intervals, carried out in the direction of travel of the web. For example, this ensures that prints, especially advertising prints, are always positioned the same way in relation to the individual bag. This means that printing can already be carried out on the continuous web of material. All bags separated later have an identical appearance.
  • markings can help the user to create equal filling levels of goods in several bags of the same type. For example, the markings are provided with volume information.
  • a stack formed from bags having at least one weld seam and at least one fold, this stack being produced using a method according to the steps described above.
  • This stack is designed to be placed in a dispenser box in order to remove bags individually from it. This provides a high level of comfort for the user, as he can always remove the individual bags from the dispenser box with the same little or almost the same amount of effort. In terms of feel, removing the bags is a positive experience for the user, as they do not have to use any force to separate the bags.
  • the dispenser box is angular in shape, for example cuboid, but also pyramid-shaped or the like, so that it can be easily stacked. Their surfaces can also be printed easily and representatively. For example, printed brands, logos, product information, warnings, price tags, advertising information and the like are better displayed.
  • the dispenser box can have at least one removal opening, which can be closed until a bag is removed for the first time.
  • a perforation can be provided to remove the closure element, with the course of the perforation reflecting the later size and shape of the removal opening.
  • a separate closure element can also be provided, which closes the removal opening until a bag is removed for the first time. Measures such as seals can be provided here, which ensure that the guaranteed number of bags per packaging unit is available to the user after purchasing the dispenser box with folded bags.
  • the dispenser box is preferably filled with at least one stack consisting of a defined number of bags. These bags have a formatting fold and, for example, a Z-fold or a U-fold. After both folding processes have been carried out, the stacks of bags are almost the same size as the inside dimensions of the dispenser box. This ensures, on the one hand, that the volume of the dispenser box is almost exhausted and, on the other hand, that the individual bags can be easily removed. The bags are removed piece by piece from the outside to the inside. The user can remove each bag individually, regardless of how the stack is folded.
  • the dispenser box can, for example, be made of cardboard, metal, plastic or composite materials.
  • the bag facing the removal opening can be fixed to the closure element for the removal opening.
  • This fixation is preferably designed so that the bag can be easily detached from the closure element after removal so that it can be put to use.
  • an adhesive point can be provided to fix the bag on the side of the closure element facing the bag in the closed state. It is also conceivable to link the individual bags in the stack using, for example, adhesive dots, so that the bag following the removed bag is always kept in or near the removal opening. If several stacks have been placed in a dispenser box, a connection between the stacks is also conceivable so that the bags forming the respective stack can be easily removed.
  • An auxiliary element such as an adhesive strip can also be attached to the bag of a stack intended for the first removal in order to form a type of handle.
  • This auxiliary element makes it easier for the user to remove the first bag.
  • Additional bags can also be provided with auxiliary elements to make it easier to remove them from the dispenser box.
  • the at least one removal opening can also be provided on the underside of the dispenser box so that gravity supports the removal of the individual bags.
  • the dispenser box is preferably arranged elevated so that the user has easy access to the removal opening arranged on the underside.
  • a mass piece can also be provided, which is arranged above the stack or the bags in the dispenser box.
  • a curved, spring-like element can also be provided opposite the removal opening in the dispenser box, which exerts pressure on the stack or the bags in the direction of the removal opening. This ensures that the bag intended for the next removal is always arranged in the area of the removal opening.
  • the bag can be made of various materials, for example plastic films.
  • the use of thin metal foils is also conceivable.
  • Web-shaped, semi-tubular, or tubular knitted fabrics, nonwovens or the like can be used in the process.
  • all web-shaped, semi-tubular, or tubular materials that can be cohesively connected can be used and are suitable for forming bags. Stacks can then be created from these bags for placement in dispenser boxes, for example.
  • any design of bags in particular plastic bags, will initially be made available in an endless web.
  • This endless web is then folded at least once symmetrically to the longitudinal axis or asymmetrically to the endless web provided, so that partial areas, possibly complete regions of the endless bag web then overlap or even lie on top of each other.
  • the individual bags that had previously been connected to one another are separated from each other at predetermined points from the folded endless web. This can be done in a manner known per se by a cutting process or processes with the same effect.
  • These individual bags folded in this way and separated from the endless web are placed on top of each other to form a package or folded further. This is done in a specified number of pieces. The number of pieces depends in particular on the volume of the dispenser box in which the folded and stacked bags are to be placed. At this point it is conceivable to fold each individual bag parallel, crosswise or at least once again in order to achieve this The format of the then folded bag must be adapted to the receiving space of the dispenser box.
  • a dispenser box is then made available in which a stack of folded bags in a specified number is placed in the dispenser box. This can then be delivered and put to use.
  • the at least one fold before the individual bags are separated from the endless web is carried out in such a way that a predetermined number of bags are available in a stack after the separation. If this stack is placed in the dispenser box, it is possible to remove individual bags from this dispenser box. An additional separation of these bags when removing them from the dispenser box is advantageously eliminated.
  • the square format of the dispenser box has the main advantage that the available space is optimally used during transport and later offering (e.g. on the shelf in the supermarket). Such a square dispenser box also offers the significant advantage that it can easily be provided with product information in a manner known per se.

These terms are not to be understood as restrictive, i.e. these references can change due to different positions and/or mirror-symmetrical designs or the like.
  • any design of bags 1, in particular foil bags will initially be made available in an endless web of goods.
  • This endless web of goods is then folded at least once symmetrically to the longitudinal axis or asymmetrically to the endless web of goods provided, so that partial areas, possibly complete areas, of the endless bag web overlap or even lie on top of each other.
  • the Figures 1A and 1B show two connected bags 1, formed from a half-tube with a lower material layer 2 and an upper material layer 3. At the point of separation between the two bags 1 there is at least one weld seam 4 for connecting the material layers 2, 3.

  • the side of the bag 1 opposite the fold 5 has an opening 6.
  • Markings 7 are placed at regular intervals near the side of the bag with the opening 6. These markings are used to process the bags 1 with repeat accuracy. These markings 7 make it possible, for example, to place the weld seam 4 with repeat accuracy. If, for example, prints, in particular advertising prints, are attached to the bags 1, they can always be precisely positioned for the individual bag 1 by welding.
