Definitions

  • the invention relates to a flexible package having a valve for venting.
  • the invention relates to such flexible packages with a resealable opening.
  • Resealable bags in particular so-called "click and close” bags, are dense bags, as a result of which the air that is in the bag can no longer escape after being filled and sealed.
  • the existing between the medium air causes, for example, that a stacking of the bag is difficult.
  • a packaging forming or integrated into a multi-layer packaging plastic film is either provided with openings, or needled or perforated.
  • the perforation can be introduced in plastic packaging on the broad sides or over certain areas of the package.
  • a multi-ply paper bag which is suitable for receiving powdered packaging material.
  • the paper bag on each of its broad sides perforations in strip or strip shape at least in the plastic liner.
  • these perforations or openings must have a correspondingly large diameter.
  • the strength of the bag is reduced. This is particularly disadvantageous when accommodating high-weight goods.
  • the object of the invention was to provide a resealable package having a device for venting the package, which closes sufficiently tight after the filling process to prevent the ingress of moisture and / or insects or other foreign bodies, such as dust grains, and the like.
  • the invention therefore relates to a package in the form of a gusseted bag with a resealable opening device and a venting device, characterized in that the venting device is introduced into the gusset, wherein the gusset partially in the form of elongated short strips with the front and back of the bag is connected so that permeable channels between these connecting strips and below these connecting strips in the gusset and the front or back of the bag substantially congruent continuous recesses are arranged.
  • the gusseted bag preferably consists of plastic films or composite films with plastic, for example of polyester, such as oriented PET amorphous PET, polyolefins such as polypropylene, cast-PP, blown, stretched, biaxially oriented PP films, or polyethylene, polystyrene, polycarbonate, cellophane, polyamide, Polyvinyl chloride or copolymers thereof.
  • polyester such as oriented PET amorphous PET
  • polyolefins such as polypropylene, cast-PP, blown, stretched, biaxially oriented PP films
  • polyethylene polystyrene
  • polycarbonate polystyrene
  • cellophane polyamide
  • Polyvinyl chloride or copolymers thereof polyethylene
  • coextruded or laminated plastic composite films or composites with paper can be used.
  • the gussets of the bag are partially connected to the front and back of the bag, preferably by welding.
  • the partial connections are preferably in the form of short strips and are spaced apart so that channels are formed between the connected strips through which air can escape in a controlled manner via the recesses.
  • the partial strip-shaped connections are offset against each other in the direction of the bottom or the lower sealing seam of the bag in the form that the situated in the vicinity of the center of the gusset connecting strips to the sealed seam of the connection of the front and back and rich further connecting strip upwards, offset from the lower connecting strip.
  • a connecting line between the seals makes an angle of about 45 °.
  • a recess is arranged in the outer third of the side fold on both sides in the side fold and in each case the front and back. These recesses may be punched and preferably have the shape of a tip.
  • the bag according to the invention may preferably be equipped with a resealable opening device.
  • the resealable opening device is designed in the form of a sliding closure.
  • FIGs. 1 to 3 an embodiment of the invention packaging is shown.
  • Fig. 1 the front view of the bag according to the invention is shown.
  • FIG. 2 the enlarged section A of FIG. 1 is shown.
  • Fig. 3 shows the bottom and side fold region of the bag according to the invention in the filled state.
