Definitions

  • the invention relates to a flexible bag with integrated opening line; a method of manufacturing such a sachet; and a machine for manufacturing such a bag.
  • flexible bag any container comprising at least two walls, in the form of sheets made from one or more materials which are flexible enough to be able to be deformed without undergoing deterioration, under normal conditions of use.
  • the walls can be made from a sheet of paper, plastic or metal such as aluminum. Frequently, they are produced from a complex multilayer film.
  • Flexible bags are known, the walls of which are arranged opposite one another. They include a rigid connection margin for the two walls against each other. The margin is arranged to delimit on the one hand the external periphery of the bag, and on the other hand the external contour of a central volume.
  • This central volume is intended to contain a product, for example pasty or pulverulent liquid. he can in particular a fluid for food, cosmetic, medical or household use.
  • This volume being surrounded, generally hermetically, by the joining margin, an opening must be formed in the walls of the sachet, to allow the product to be discharged therefrom.
  • Such an opening can be achieved using a cutting tool such as a pair of scissors.
  • a line of weaker resistance intended to allow the opening of the bag, without cutting tools, as a result of the tearing or tearing of the walls.
  • a first end of the line of weakest resistance is located at the outer periphery of the bag.
  • At least one wall comprises a layer of a material supporting without breaking significant elastic deformations
  • the opening obtained is not always clear, and does not allow clean unloading and precise dosing of the product .
  • the tear deviates from the direction in which it is desired to be carried out. And part of the walls are torn off without the bag being opened. Or that the tear is diverted towards the inside of the volume, and creates a breach in it such that the product tends to leak out of the sachet.
  • the invention aims to overcome these drawbacks among others. And to offer a flexible economic bag to be produced, which is both mechanically resistant, able to offer effective protection of its contents, while being able to be opened easily.
  • An object of the invention is a bag comprising two flexible but tearable walls arranged opposite; a rigid joining margin of the two walls against each other, arranged to delimit on the one hand the outer periphery of the bag and on the other hand the external contour of a central volume intended to contain a product, for example liquid, pasty or powdery; and a line of weaker resistance which extends over the joining margin and which is intended to allow the opening of the bag as a result of the tearing of the walls; a first end of the line of weakest resistance being situated at a peripheral edge of the joining margin; characterized in that at its second end the line has a tangent which intercepts the external contour of the volume, so that by tearing the walls along the line of weakest resistance, from the first end and via the second, an opening of substantially predetermined shape is made in the volume.
  • the walls of such a bag can either be separate, and for example from two sheets of flexible material. Either these walls come from the same folded sheet so as to obtain two facing walls.
  • the line of weakest resistance may be in the form of a thinning of the thickness of at least one wall, a stamped line, or a removal of material.
  • the line of weakest resistance can be interrupted between its first and second ends, by at least one frangible bridge.
