Definitions

  • the present invention relates to a packaging of the reclosing type 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.
  • 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 reclosing type packaging consisting of a relatively rigid outer envelope and a flexible inner bag with bellows, integral with said envelope, in which the outer envelope comprises at least one flap whose fold for closing folds and clamps the two sides of the end of the bag and the two side walls of the outer velvet are free from moving parts.
  • mobile parts is meant in the present description, for example triangular tabs which normally allow folding of the bellows of the inner bag.
  • 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 outer envelope comprises a flap which is in the extension of the dorsal wall of said envelope, said foldable flap and pinching the two faces of the end of the bag around from the upper edge of the front wall of the enclosure at an angle between 90 and 180 °.
  • a means of securing the back wall and the front wall of the outer envelope is provided, for example a Velcro type fastening system or any other means known in the art.
  • the fold angle of the end of the bag is preferably between 110 and 150 °.
  • the envelope comprises a flap provided with an extension and a flexible member cooperating with the extension of the flap to keep the latter in the open or closed position, said folding flap and pinching the two faces of the end of the bag at an angle between 90 and 180 °.
  • the fold angle of the sachet is preferably between 140 and 180 °.
  • the envelope comprises a 'sheet folded back on itself so as to form a flap and, in the closed position, a rectangular volume cooperating with a second flap also forming in the closed position a parallelepiped volume, said parallelepiped volumes cooperating with each other to pinch the two faces of the end of the bag.
  • the end of the bag is partially glued to the rectangular volumes so that the opening of the flap causes the opening of the bag.
  • 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 and / or water tight. 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 essentially consists of at least one relatively rigid sheet of cardboard, coated or coated cardboard, of plastic material for example, 0.4 to 1.5 mm thick. In a preferred embodiment, it has a square or rectangular base and the closing flap is at the top.
  • the outer envelope 17 surrounds a bellows bag 18, in which is the packaged product.
  • the side walls 19 of the envelope have no folding tabs.
  • the flap 20 extends the back wall 21 of the outer envelope and folds and pinches the two faces 24 of the end of the bag 18 around the upper edge of the front wall 22.
  • the end of the bag extends after the preferably folds from 5 to 30 mm.
  • a Velcro type 23 fastening system makes it possible to secure the flap 20 to the front part 22, so as to keep the packaging closed, especially when it is already in use.
  • the outer envelope 1 surrounds a bag 2 leaving the sides of it free.
  • the envelope is made of two sheets glued together at the bottom, so that the bottom can be filled before gluing.
  • the envelope 1 is made of a single sheet.
  • One of the faces of the envelope 1 comprises a shutter 3 provided with an extension 4 and a flexible member 5 cooperating with the latter to keep the shutter 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 2, the package is open, and the flexible member 5 maintains it in this position.
  • the top of the faces of the envelope 1 are brought closer and the flap 3 is folded back beyond the neutral point of the flexible member 5 as shown in Figure 3, 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 a good closure of the packaging.
  • the outer envelope surrounds a bag on at least four sides, constituting a box.
  • a part of this envelope is folded back in the closed position ( Figure 4) along the edges 6, 7, 8, 9, then is glued to the outer wall, forming a rectangular volume A.
  • Another part of the envelope is folded according to the edges 10, 11, 12, 13, 14 and glued to the outer wall, forming a parallelepiped volume B and a flap 15.
  • the end 16 of the inner bag is glued to the volume A along the edge 8 and to the volume B along edge 13.
  • the opening works as follows: The flap 15 is raised, which pivots around the edge 10.
  • the contour of the volume B behaves like a deformable parallelogram whose fixed pivots are the edges 10 and 14 and the mobile pivots the edges 12 and 13. This means that the part between the edges 12 and 13 pivots up and to the left . Due to the bonding along the edge 13, the left part of the end of the bag 16 follows this movement, and due to its bellows constitution, the bag tends to open on both sides. The right part of the end of the bag 16 is driven upwards by its left part and due to the bonding along the edge 8, the part between the edges 7 and 8 is first pulled upwards. As with volume B, the outline of volume A constitutes a deformed parallelogram ble around the fixed pivots 6 and 9 and the part between the edges 7 and 8 pivots up and to the right. By removing the flap 15 and the volume A, a total opening is shown, shown in FIG. 5, where the volumes A and B are completely flattened.
