Definitions

  • the present invention relates to improvements made to flexible packaging with expulsion system for their content, of the type comprising a tube extended by a nozzle or a cannula.
  • Such devices are generally used to inject liquid or pasty products into the human body or that of an animal.
  • Devices of the type in question are known, manufactured either in one piece or in two parts and which contain the exact dose of product necessary for an application.
  • the first are generally made of plastisol, that is to say obtained in the known manner by autor molding of a heated mandrel which is dipped in a bath of this material.
  • the second consist of an extruded tube open at its two ends, one of which is welded to the base of a tip or cannula while the other is closed by pinching once the active product has been placed in the tube.
  • All these devices comprise a junction between the tube and the cannula which constitutes a shoulder offering a resistance to crushing greater than that of the rest of the tube.
  • Document AU-A-414 085 also discloses a tube, the junction of which with its discharge cannula is produced by means of a collar with two inverted curvatures, but this collar is not irreversibly deformable.
  • the improvements which are the subject of the present invention aim to remedy these drawbacks and to allow the production of a device of the type in question which is of a very low cost price and avoids too great a loss of active product.
  • the packaging according to the invention is produced by injection under pressure of a plastic material, the junction between the tube and the cannula being produced in the form known per se of a neck with two reverse curvatures while the thickness of this neck is thinner starting from the cannula in the direction of the tube, which allows irreversible deformation of the tube and the neck by crossing an unstable equilibrium position.
  • a device according to the invention essentially comprising a flexible packaging 1 and a shutter 2.
  • the packaging 1 is produced in one piece by pressure molding of a plastic material such as polyethylene or EVA (ethylene-vinyl-acetate). It comprises a tubular skirt with constant section 3 which is extended by a cannula 4. The tube 3 and the cannula 4 are connected by a neck 5 with two inverted curvatures of the kind encountered on the bottles.
  • the free end 4a of the cannula is rounded so as not to hurt when it is put in place, it has a central expulsion opening 4b with calibrated diameter.
  • the thickness of the cannula is of the order of 0.7 mm, that of the neck 5 decreasing in the direction of the skirt 3 so as to be connected to the latter whose thickness is of the order of 0 , 4 mm.
  • the radii of the neck are chosen so that it constitutes a guard against untimely sinking of the device.
  • the connecting radii from the neck to the cannula and to the skirt are 25 and 12 mm respectively.
  • the bottom of the skirt 3 is thinned over 4 to 5 mm in height to form a zone 3a facilitating the welding once this skirt has been flattened after filling of the device with the active product (fig. 2) in the inverted position. that is, the cannula oriented downwards and closed.
  • the obturator 2 is produced in the form of a cap 2a with a rounded bottom, the internal diameter of which is determined so as to engage freely on the end of the cannula.
  • the bottom of the obturator comprises an internal stud 2b, the diameter of which is determined so that this stud penetrates by force into the opening 4b of the cannula 4.
  • the stud may include peripheral cords, not shown, capable of increasing the force of retention of the shutter relative to the aforementioned opening.
  • the device Once the device is filled with active product, it has a cross-section as shown in fig. 3, that is to say that the bottom of its skirt constitutes a straight edge 3b determined by the welding of the zone 3a after its flattening. The presence of the edge 3b causes the deformation of the entire skirt 3 which then forms just before the neck 5 two symmetrical bulges 3c, 3d.
  • the packaging 1 advantageously has a volume corresponding to the exact dose of active product which must be used for an application. For example, this package 1 contains the exact dose of a micro-enema in the form of a gel.
  • the entire product is expelled, the loss representing only the volume contained in the cannula.
  • the plastic material used for injecting the device according to the invention has a molecular weight high enough to avoid the formation of cracks at the welded edge 3b.
  • cannula 4 could be replaced by a nozzle of any shape adapted to the type of spillage of the product contained in the packaging.
