Definitions

  • the invention relates to the technical sector of plastic packaging bags, in particular of the type intended to receive animal feed, in the form of granules for example.
  • the invention relates to a gusseted bag according to the preamble of claim 1 and to a method of manufacturing a plastic bellows bag according to claim 1.
  • these types of bags have, in a manner perfectly known to a person skilled in the art, bellows capable in particular of increasing the capacity of the bag. These bellows are formed at the longitudinal edges of the bag, between two walls constituting the front face and the rear face of the bag. These bellows are made, most often, over the entire height of the bag.
  • the bags are made from a roll of a plastic film which is unrolled continuously.
  • the plastic film is subjected to operations to delimit, between its two longitudinal edges, a portion intended to constitute the front face of the bag, a portion intended to constitute one of the bellows, a portion intended to constitute the back side of the bag and a portion intended to constitute the other bellows.
  • the film is then subjected to various successive bending, cutting and welding operations, to produce a bellows bag with a bottom and generally a filling opening.
  • the upper portion of the bag, opposite the bottom usually has, above a sealed closure zone, arrangements constituting a gripping handle.
  • a handle disposed substantially at half a length of one of the longitudinal edges bellows of the bag, is constituted by a strip of heat-sealable material on the bag.
  • the length of the band is equal to the developed transverse length of the bellows increased by the length of two extreme returns fixed by welding on the corresponding outer edges of the bellows considered.
  • a handle is made from an opening formed in a part which extends each of the folds of one of the bellows.
  • one of the bellows of the bag has folds of length at least twice the length of the folds of the other bellows.
  • a weld line formed at a determined distance from the fold of the two folds of great length makes it possible to produce identical bellows on each side, one of which has, in all of its length, a free band in which can be formed the grip handle.
  • This embodiment therefore increases, in a useless manner, the width of the container bag considered and obviously requires an excess material significantly increasing the manufacturing costs.
  • a bellows bag according to the preamble of claim 1 is known from the document US-A1-5186 542 .
  • the object of the invention is to remedy these disadvantages in a simple, safe, effective and rational manner.

  • the PET does not allow to perform a weld.
  • bellows plastic bag for food products the bellows being formed at the longitudinal edges of the bag and resulting from two internal folds formed from a median line and connecting, by connecting areas, the front face and the rear face of said bag.
  • At least one of said bellows has arrangements acting as a handle.
  • the arrangements consist of openings formed in the thickness of the folds of the bellows, facing an insert which is fixed inside the folds of the bellows sealingly.
  • the arrangements consist of openings formed in the thickness of the folds of the bellows, substantially in the middle of the length of said bellows and facing the insert which is fixed inside the folds of the bellows, in a sealed manner.
  • the openings are of substantially oblong general shape and are arranged symmetrically, on either side of the median line of the two folds, delimiting a central band which constitutes the handle as such, after having introduced a hand through said openings .
  • profiled slots may be formed transversely in the thickness of the folds of the bellows, opposite the insert, and on both sides openings.
  • the arrangements consist of profiled slots formed in the thickness of the folds of the bellows, facing the insert which is fixed inside the folds of the bellows, in a sealed manner, said slots being arranged symmetrically, on either side of the median line of the two folds, delimiting a central strip which constitutes the handle as such after having introduced a hand through said slots.
  • the handle as such is made directly from the material constituting the bag.
  • the arrangements are constituted by slots or openings formed in the thickness of the insert which is attached to the outside of the folds of the bellows substantially in the middle of the length of said bellows.
  • the slots or openings are formed symmetrically on either side of the center line of the insert by delimiting a central strip which constitutes the handle as such, after having introduced a hand through said slots or openings.
  • this insert is fixed at its longitudinal edges only, near the connection areas of the folds of the bellows with the front faces. and back.
  • the insert has a substantially quadrangular planar shape.
