Definitions

  • the present invention relates to a reclosing type packaging consisting of a relatively rigid outer envelope and a flexible inner bag with bellows.
  • US Patent 2,463,313 relates in particular to such a method, according to which a good seal is ensured by a specific way of folding and of application of heat and pressure on the inner bag.
  • US Patent 3,392,901 relates to a reclosing type package comprising an outer carton and an inner envelope.
  • this packaging is not very easy to handle. Indeed, it has a tear-off tab, it requires a double folding of the internal and external envelope and finally the closing and reclosing are not done in the same way.
  • the problem underlying the present invention is therefore to find a packaging of the reclosing type, guaranteeing a good seal and impermeability, that is to say a good shelf life of the product after opening the packaging.
  • the packaging of the reclosing type according to the present invention makes it possible to make such packaging available to consumers.
  • the invention relates to a packaging of the reclosing type consisting of a relatively rigid outer envelope and a flexible inner bag with bellows, integral with said envelope, in which the envelope comprises at its upper part and on its back wall a first flap provided with an extension directed in the open position or unfolded towards the bottom and in the closed position or folded upwards and on the other hand a second flap cooperating with the extension of the first flap to keep the packaging in the open or closed position, said first folding and pinching flap in the closed position the two faces of the end of the bag on the edge of the front wall at an angle between 90 and 180 °.
  • the fold angle of the sachet is preferably between 140 and 180 °.
  • the reclosing type packaging according to the invention finds applications especially for the packaging of food products, but is also conceivable in other industrial sectors.
  • packaging is provided each time a product sensitive to air and / or humidity is conditioned and / or a product whose preservation of the aroma is essential, for example soluble coffee or roasted.
  • the inner bag is a bellows bag, made from a thin sheet of 0.02 to 0.3 mm thick.
  • the nature of this sheet depends on the product to be packaged: possibly coated paper, plastic material such as polyester, metallized if necessary, aluminum complex, etc. depending on whether the sachet must be moisture-proof and / or l for example.
  • the sheet is heat sealable.
  • a strip is folded longitudinally on itself and sealed edge to edge, then sealed transversely at one end after forming the side bellows, after which the bag is filled and sealed transversely at the other end.
  • the lower end is flattened to adapt to the bottom of the outer envelope.
  • Another method of forming a bellows sachet consists in folding the two edges of a strip longitudinally over the depth of the bellows, then folding the strip transversely so as to bring the lateral edges inside and to join them together. weld together. The bag is then opened at one end with which it is filled, then this end is sealed and preferably flattened to form the bottom.
  • the upper part of the bag is provided with a tearing member such as a wire or a strip. Otherwise, the sealed bag can be opened by cutting the upper part.
  • the outer envelope (1) surrounds a bag (2) leaving free the sides thereof.
  • the envelope is made of two sheets glued together at the bottom, so that the bottom can be filled before gluing. Alternatively, if the filling is done from above, the envelope (1) is made of a single sheet.
  • One of the faces of the envelope (1) comprises a first flap (3) provided with an extension (4) and a second flexible flap (5) cooperating with the latter to keep the flap (3) open or closed.
  • the upper end of the bag (2) is glued to the envelope (1) on the side of the flap (3).
  • the package In the position shown in Figure 1, the package is open, and the second flexible flap (5) maintains it in this position.
  • the top of the faces of the envelope (1) are brought together and the flap (3) is folded beyond the neutral of the second flexible flap (5) as shown in Figure 2, so that the flap (3) is kept in the closed position.
  • the two faces of the end of the bag (2) are then folded and pinched by the flap (3), ensuring that the packaging is properly closed.
  • the end of the bag (2) extends after folding, preferably 5 to 30 mm.
