Definitions

• the present invention relates to a flexible-walled package, such as a bag or an outer plastic bag, for containing a first product and at least one flexible inner pouch that can be broken or torn containing a second product in form. a liquid, powder, gas or gel form for mixing with said first product in said bag or said outer bag.
• This type of packaging finds application in a good number of industrial fields, for example in the field of cosmetics, in particular the products
• This kind of packaging is also useful in chemiluminescent applications, such as chemiluminescent lighting elements in which light is produced by reaction between two products which have been allowed to mix.
• EP-1421314 discloses an aluminum foil pouch containing a solution of an oxalate disposed within a translucent plastic film pouch also containing the activating solution.
• the device comprises a steel ball or grain of hard material whose role is to disembowel the aluminum bag at the time of use, under the effect of the manipulation of the user.
• This device has certain drawbacks including the risk of unwanted piercing of the inner bag during various manipulations, including during manufacture, filling, transport and / or prolonged storage.
• the multilayer laminated packaging films are very resistant, as a result of the materials chosen for their manufacture, in particular polyethylene, polypropylene or PVC as first layer,
• the object of the invention is therefore to provide a
• packaging of the aforementioned type which is suitable for the mentioned fields of application and which possibly makes use of known multilayer laminated packaging films, and which comprises means for breaking the internal bag while reducing the risk of unwanted rupture of the outer bag .
• This object is achieved by providing a packaging of the aforementioned type provided with a breaking means which consists of a substantially rigid but foldable plate - preferably without breakage - which comprises a preferred region or fold line and on which is fixedly secured to the less an internal pocket.
• the internal pocket occupies essentially the entire surface of the wafer.
• the wafer may comprise two internal pockets.
• a preferred fold line consists of a groove practiced on a significant depth of said wafer.
• the upper edges of the groove can thus promote tearing of the film or sheet.
• the rupture of this film which forms the internal pocket therefore allows the mixing and reaction of the product contained in this inner bag with the product contained in the outer pocket.
• the preferred fold line initially rectilinear, may be interrupted by a drawing in the shape of a bend or tooth, so that when the wafer is bent, this bend or tooth forms a protruding portion which exerts an even greater traction on the adjacent film secured to said wafer. This traction,
• the film or sheet constituting the internal pocket has a notch or primer facilitating tearing.
• this notch or primer is arranged to act in cooperation with the preferred fold line of the wafer or, when this fold line comprises one or more bends or teeth, in cooperation with the support of this bend or tooth on the adjacent film when folding said wafer, so to further facilitate the tearing or breaking of the internal pocket in question.
• the wafer is dimensioned such that these lugs or tongs of the inner bag can be folded around the corresponding end edges of the wafer and glued, riveted or welded on the wafer face opposite the face adjacent to the pocket. .
• the fastening means collaqe, rivetaqe or soudaqe at the level of the wafer, will be located at least at the abscissa of the cut, tooth, elbow or bossaqe.
• the pliaqe of the wafer causes breakage or breakage that can lead to the two-part separation of said wafer.
• FIG. 1 shows a folded plate according to a preferred embodiment of the invention
• FIG. 2 shows an internal pocket according to an advantageous embodiment of the invention
• Figure 3 shows the assembly of the internal pocket secured to the folded plate, seen from the opposite side to that of Figure 1;
• FIG. 5 illustrates the assembly of the pocket of Figure 4 with a folded plate
• FIG. 6 illustrates an internal pocket according to yet another embodiment of the invention
• FIG. 7 is a view similar to that of the
• Figure 3 an assembly using the inner pocket of Figure 6; and - Figure 8 shows an alternative embodiment of the support plate.
• the invention thus relates to a flexible-walled packaging, such as a bag or an external plastic bag, for containing a first product and at least one flexible inner bag which can be broken or torn containing a second product
• substantially liquid or gel form for mixing with said first product in said bag or outer bag to generate light, heat, cold or to produce a cosmetic or pharmaceutical or other mixture.
• a means for breaking the inner bag which consists of a plate 1 having a preferred fold line 2 consisting of a groove made in the thickness of the wafer allowing it to articulate easily on both sides of this groove.
• the inner pocket 5 is secured to the wafer 1.
• the wafer 1 is advantageously sized to fit in the bag or the outer pocket.
• the preferred fold line (groove 2) is locally interrupted by a bend-shaped cut-out 3 so that during bending there is obtained a protruding element or linear boss 4 which exerts a pulling force on the film of the secured pocket to said wafer.
• the inner bag 5 may consist of a multilayer laminated film known per se, or an aluminum foil coated with a welding varnish, and hermetically sealed to contain a substantially fluid product, for example a liquid, a powder or a gel.
• This pocket may advantageously comprise a notch or incipient fracture 6 facing the boss obtained during the folding of the wafer on which the inner bag is applied.
• the wafer has essentially the same surface as that of the inner bag.
• the assembly can then be placed in an outer or multilayer laminated plastic bag, preferably translucent, which still receives a second product before being hermetically sealed.
• two tabs 8, 9 or flaps are provided on two opposite sides of the inner bag.
• the bag is then deposited on the wafer 1 on the face having the groove 2 so that the tabs 8,9 extend beyond the wafer and parallel to said groove. These tabs are then folded on the opposite side of the wafer and advantageously welded or glued.
• the pockets can be made in a manner known per se.
• a film strip segment can be used, folded and soldered on three edges; the legs or tongues can then be applied separately by gluing or welding or they are constituted by overflow of material on the welded sides.
• Pockets with tabs can also be formed by superimposing two films welded on four sides.
• a rectangular inner pocket and hermetic 14 (see Figure 6) slightly different from that of Figure 2 by the dimensions of the tabs.
• the film of the bag consists of a film with three layers including an outer layer of polyester, a sheet of aluminum and a layer
• the pocket further comprises a notch 6 of about 1 mm made in the welded zone.
• a wafer made of polypropylene or HDPE high density polyethylene having a thickness of 1.5 mm is substantially equal to the bag without its legs grooved on the lengths CD and EF to a depth of 1.2 mm. .
• a cut 3 forming an elbow 4 is formed forming an arc with a radius of 6 mm.
• the bag 14 is placed on the plate 1 side groove 2 and positioned so that the notch 6 is at the highest level of the arc formed by the bend or boss.
• the tabs 8, 9 of FIG. 7 are folded on the opposite side of the plate, stretched and welded on the plate 1 on the lengths GH and IJ.
• the assembly can be introduced into a transparent polypropylene outer bag, sealed on three sides and dimensioned for this purpose. Another liquid is introduced into this pocket and the last side is sealed in turn.
• the lugs 8.9 were welded to the wafer 1 for a short distance advantageously positioned relative to the boss.
• the force exerted during the folding of the plate focuses on the pocket only GH and IJ thus facilitating the rupture of the pocket.
• two bags similar to those of Example 1 are made, each containing a different liquid.
• a notch 6 is made in the same manner as in Example 1 on each of the pockets.

• a boss-forming cutout 16 forms an arc LM of radius 6 mm and diameter LM.
• a second cutout 18 forming the same boss 19 is made which forms an arc NW of radius 6 mm and diameter NO.
• This embodiment is advantageous when the two contents require packaging in a multilayer barrier laminated bag to ensure their good preservation over time or when the mixture that is desired to obtain is a mixture of three components, the third being contained in the outer pocket.
• the wafers can be obtained by cutting and grooving plates made in a manner known per se.
• the wafers can also be produced on a large scale by injection molding, obtaining in a single step wafers with their grooves.
• the wafer may have different outlines
• the word wafer covers any element presenting a more or less central and foldable flat zone and can therefore take very different shapes.
• the wafer thus defined may comprise non-foldable rigid areas or projecting rigid parts.
• the wafer may also be made in two parts contiguous to each other in the plane of the groove or slot, with hinge reported, flexible material, thus replacing an integral hinge.
