Definitions

  • the invention relates to a bag with a gusset.
  • the invention further relates to a method for producing a bag according to the first paragraph.
  • the pouch described therein has a side fold placed between a front wall and a back wall and a reclosure disposed on the inside for forming a reclosable chute in the side fold. Due to the location of the reclosure on the inside of the gusset, a user of the pouch must open the chute through an opening in the side fold with at least one finger or fingernail to extract a portion of the gusset to form the chute the reclosure opens.
  • the subject of the invention is therefore a bag made of a film and a front wall and a rear wall and a head portion and a foot portion and at least one gusset extending longitudinally between the head portion and the foot portion connecting the front wall to the back wall having an outer side and an inner side, the side gusset having an opening portion with an inner closure reseal to form a reclosable chute, and having actuating means for actuating the reclosure disposed adjacent to the gusset portion on the gusset, the actuating means including a grip portion for engaging and a fastening portion for securing the reclosure Fastening the handle portion have on the gusset and are particularly arranged and shaped, as defined in claim 1.
  • the subject of the invention is a method for producing such a bag.
  • the various walls of the bag may be present as individual wall segments and joined together by gluing or sealing their edges. Also, extrusion seams are possible. Also, a film may be formed into a tube and contacting edges of the film sealed together to make the bag. In addition, in such a tube shape by folding the tube wall, a side fold or two side folds can be produced. At such fold edges and the structure of the bag reinforcing longitudinal sealing seams may be formed.
  • the head area and / or the foot area can be flat-shaped or realized in the form of a fin.
  • the opening region can be formed by an opening already prefabricated in the film, for example by punching out a film part, or by a cut.
  • the opening region can also be formed by an originally closed part of the film, which is opened only when the bag is first opened or removed from the bag.
  • the opening region may have a weakening of the material that delimits the opening, which weakening of the material defines a region of a flap that can be completely or partially released from the lateral fold, wherein after removal of the tab, a chute can be formed.
  • the weakening of the material can be produced by the action of a laser beam or by the production of a perforation or embossing. There may also be a combination of these measures.
  • the material weakening may be a continuous line or in the form of a broken line.
  • the opening may already be incorporated into the film and this opening may be closed by an additional closing tab applied on the outside of the film which must be torn away from the opening to open it. In both cases, an original packed condition can be detected when the opening is completely closed, so there is no damage to the tab.
  • the opening area may be defined prior to processing the film into a bag, for example during its manufacture. However, the opening area can also be defined in the course of processing the film into a bag.
  • a chute is formed with the opening opened through a portion of the gusset adjacent to the opening portion, which is pulled away from another portion of the gusset which is on the opposite side of the opening portion, or drawn out of the area between the front wall and the rear wall.
  • a film As a film, a single-layer film or a multi-layer film can be used.
  • a multilayer film may e.g. be made by laminating or coextrusion.
  • the inventive measures is achieved in an advantageous manner that an opening and closing of the chute without an intervention in the chute or a contact with the gusset in the region of the chute and thus without contamination of the finger or the fingernail of a user is feasible.
  • an ergonomically preferred opening of the reclosure but also a reliable closing of the reclosure be achieved.
  • the user can not freely engage in the gusset or between the adjacent front and rear walls from above or visually inspect the correct position of the reclosing elements from above.
  • the shape and / or the size or opening width of the chute can be well stabilized and dynamically changed during the pouring out of the packaged goods.
  • the measures according to the invention have proved to be particularly advantageous if the reclosure has a closure area covering the opening area and bordering areas adjacent to it, and this is fixed along its edge with the opening of a contiguous area on the inside of one gusset and if both in the contiguous area on the inside of a side fold fixed first Velcro as well as a cooperating, are fixed to the Verschgreslasche second Velcro strip are arranged. Since the second Velcro fastener fastened to the inner side of the closing flap can not be engaged behind from the outside in order to press it against the first Velcro strip, it is particularly important that the first Velcro strip be reliably guided to the correct position with the aid of the actuating means and be there with sufficient Force on the second Velcro tape is pressed.
  • the two Velcro strips can be designed differently.
  • the first and second Velcro strips are identical.
  • the first Velcro strip extends under the opening over its entire length.
  • the second Velcro strip is fixed on the first Velcro side facing the Verschschlasche.
  • the edge of the closing flap fixed to the inside of the side fold runs in reverse U-shaped, wherein the U-web is oriented and arranged in the direction of the head region and the two U-legs adjoining the U-web extend downwards in the direction of the foot region.
  • the first and second Velcro then preferably extend between the two U-legs of the edge of the closure flap.
  • the first and second Velcro strips can be fixed to the inside of the side fold or to the first Velcro side facing the Verschwinlasche by gluing or sealing, wherein in the case of sealing two adjacent to the closure elements of the Velcro arranged sealing flanges by sealing with the inside are connected.
  • the opening region may have a material weakening which delimits the opening, which weakening of the material defines a region of a flap that can be completely or partially released from the lateral fold, wherein after removal of the tab the chute can be shaped.
  • the weakening of the material can be produced by the action of a laser beam or by the production of a perforation or embossing. There may also be a combination of these measures.
  • the material weakening may be a continuous line or in the form of a broken line.
  • the opening may also already be incorporated in the film, and this opening may be closed by an additional closing tab applied on the outer wall of the film, which has to be torn away from the opening in order to open it. In both cases, an original packed condition can be detected when the opening is completely closed, so there is no damage to the tab.
  • the grip area is oriented parallel to the longitudinal direction and the side fold has a central fold line extending in the longitudinal direction and the end of the grip area attached to the side fold is positioned congruently to the fold line.
  • one end of the gripping area is easily graspable because it can be easily lifted off the outside of the gusset.
  • the other end of the grip area is located exactly at the position of the fold line and runs exactly following the fold line. It can thus be done precisely at the location of the fold line, the power transmission, which is particularly important for the precise interlacing of those of the fold line of the gusset following parts of the closure elements of the reclosure important.
  • the attachment area to the left or to the right side of the grip area is connected to the side fold.
  • the fastening region is divided into a first fastening region and a second fastening region and the first fastening region extends adjacent to the end of the grip region fastened to the lateral fold toward the front wall and the second attachment portion extends adjacent to the gusseted end of the handle portion toward the rear wall.
  • the two attachment areas may be glued to the outside of the gusset.
  • the gusset has a slot at the position of the fold line, through which the two attachment areas are guided into the interior of the bag and the two attachment areas are arranged on the inside of the gusset. They can be arranged either on the left or on the right side of the slot. Again, for reasons of symmetrical power transmission, it is advantageous for one attachment area to be located to the left side of the slot and the other attachment area to the right side of the slot is. There they can be glued to the inside of the gusset.
  • the inside of the gusset has a sealable layer, they may also be individually sealed there, whereby a reliable and inseparable within the intended use connection between the mounting portion and the inside of the gusset is obtained and consequently a reliable power transmission both in the train so also reached in the printing phase.
  • the two attachment areas and the slot with a cover sheet are preferably completely covered.
  • the inside of the gusset has a first sealable layer and the cover sheet has a second sealable layer which on that side facing the inside of the cover sheet is arranged, and at least one area around the slot, preferably a region around the slot and the two attachment areas is sealed by sealing with the cover sheet.
  • a region of the cover sheet and / or the fastening region between the inside of the gusset and a part (mounting flange adjacent to a closure element or the closure element itself) of the reclosure is inserted, preferably glued, especially preferred sealed.
  • the preferred positioning between the reclosure and the inside of the gusset enables precise force transfer between the gripping area and the part of the reclosure associated with the inside of the gusset. Thereafter, the area of the slot is completely covered by a cover sheet and finally the interior of the bag is hermetically sealed at the location of the slot by the cover sheet.
  • This embodiment is made in accordance with the method of the present invention such that the slot is formed at the position of the central fold line in the side gusset in the longitudinal direction of the gusset, and positioning of the actuating means in the slot is performed so that the grip portion is toward the outside protrudes from the slot and the attachment portion protrudes toward the inside out of the slot, and the two attachment portions are fixed to the inside of the side fold with respect to the slot in the opposite direction on the inside.
