Definitions

  • the invention relates to the technical sector of packaging and more particularly to plastic or plastic bags, intended to be filled with any products.
  • the invention finds a particularly advantageous application in the case of packaging bags for receiving animal feed, especially in the form of croquettes, granules, etc.
  • this type of packaging has a bottom from which are formed, between two walls, the lateral edges arranged in parallel.
  • the side edges are shaped to act as bellows, to increase the capacity of the bag.
  • these bags can be made continuously, from a single plastic film. Essentially, and in a perfectly known manner, the film is subjected to successive bending operations to achieve lateral bellows between the two walls.
  • the outer plies thus produced are generally assembled by welding operations.
  • the bottom of the bag is usually made continuously by welding, then folded down and attached to one of the walls of the bag.
  • the problem to be solved by the invention is to make it possible to easily pour the contents of a bag with a relatively precise flow, whatever the size of the products, with the aim of being able to temporarily close the discharge opening in an economical manner, in other words without having to equip said opening with additional temporary coupling means.
  • the bag has, on both sides of the opening, arrangements adapted to direct and channel the products towards said opening, as and when spill.
  • the arrangements consist of a weld line oriented towards the opening and made at the top of the bellows.
  • the temporary closure means is an attached band which one of the faces is treated to be self-adhesive and repositionable.
  • the angularly oriented welding lines are produced after filling the bag, in the same way as a closing weld of the upper part of the bag. and from which is formed the precut.
  • the realization of the packaging bag (1) of flexible or semi-rigid plastic material is of any type known in this field.
  • the bag is obtained from a film subjected to successive bending operations to produce side gussets (1a) and (1b) between two walls (1c) and (1d).
  • the upper edge of the bag (1f), after filling, is, in a perfectly known manner, closed by a weld line.
  • a pre-cut (1g) giving free access to the interior of the bag defining, after tearing, opening spill (1h) of the products contained in the bag.
  • the opening (1h) is located substantially in the middle part of the bag, between the two bellows (1a) and (1b) and has a rounded profile substantially shaped cradle.
  • the width and the depth of this opening (1h) are adapted to the spill of the product.
  • the bag has, on either side of this opening (1h), arrangements for directing and channeling the products towards said opening, as and when spill.
  • welding lines (S1) and (S2) are formed at the upper end of the bellows (1a) and (1b) being oriented towards said opening.
  • welding lines (S1) and (S2) angularly oriented to direct, as indicated, the products in the direction of the discharge opening (1h), may be shorter length, equal to or greater than the width of the folds of the bellows (1a) and (1b), whether or not connected to the upper weld line (S3) ( figure 5 ).
  • these weld lines (S1) and (S2) are made after filling the bag, in the same way as the weld line and closure (S3) to the upper part of the bag and from which is formed the precut (1g).
  • precut (1g) is connected to the weld line (S3) by tear primers (1i).
  • the bag has a temporary closing means (2) disposed on one of the walls (1c) or (1d) of the bag.
  • This temporary closure means (2) is shaped to be repositioned at will through the opening (1h) in the folded position of the upper part of said bag in order to maintain, in this position, said upper part corresponding to the closure of the opening (14).
  • This temporary closure means (2) may be constituted by an attached strip, one of whose faces is treated to be self-adhesive and repositionable.
  • one of the ends of this strip (2) has a non-adhesive portion (2a) for gripping.
  • the bag (1) can be equipped with one or more handles to facilitate its grip at the time of the particular spill.
  • this handle may be disposed at the bellows or, preferably, particularly in the case of a larger capacity bag, substantially at the middle portion of one of the walls of the bag.
