Definitions
- the subject of the invention is a new flat closure system, suitable for sachet type packaging, in particular plastic.
- These packages or sachets can be "Doypack” or sachets called “three welds”.
- GB-A-826 784 describes a sachet which is obtained by successive folding of a plastic film. This film is folded for the first time along a straight line carrying a central orifice, two V-shaped welding zones are applied, then the film is folded back on itself. The three free sides are welded, as well as part of the fourth side carrying the bellows with the V welds. The presence of the opening at the bottom of the bellows, as well as the presence of the two V welds and the partial weld on the side. of the opening, would allow correct operation of the valve formed by the central orifice.
- FR-A-2 711 115 describes an inflatable bag provided with a valve.
- This sachet is obtained by forming two parallel seals in a film folded back on itself, which is then again folded back on itself, in a similar manner to that of GB-A-826 781. In this case however, the double folded film is welded so that the folded film edges are accessible from the outside.
- WO-A-95/23742 describes a complex system obtained by successive folding with intermediate welding steps.
- the bag obtained is double walled.
- the valve system consists of an attached film, which is pierced by the application of a straw.
- This film can be made of aluminum or polymer.
- an orifice is formed by welding along two parallel lines (between which the straw will be placed). This part is then folded over the sheet which is welded along its ends. Another sheet is then added to form the container. The straw pierces the lid, but when the straw is removed, the two walls are pressed against each other by the pressure of the fluid.
- Document JP-A-09-254999 describes a synthetic resin sachet.
- the bag consists of two films hermetically sealed laterally.
- a strip is arranged parallel to a jaw between the two films.
- the strip is partially provided with a non-adhesive part. This adhesive part serves as a flow opening.
- FR-A-1 436 217 describes a process for manufacturing a packaging bag for beverages. According to this process, a vacuum formed by a sheet of thermoplastic synthetic material is emptied by means of a torch.
- the goatskin is made from a side-pleated tube drawn from a thermoplastic synthetic sheet. The torch is inserted into the bottle between the lateral folds applied one against the other.
- the invention makes it possible to remedy the defects of the systems of the prior art.
- the invention provides a packaging comprising at least two sheets and two flexible films arranged between them and welded to the sheets by the welds respectively, and welded to each other and to the sheets by the welds, at least one of the two films being folded over the other at the end of the films, opposite the welds.
- the two films being folded back on themselves at the end of the films opposite the welds.
- the packaging comprises at least two sheets and two flexible films arranged between them and welded to the sheets by the welds respectively, and welded together by the welds and to the sheets by the welds, the welds being between the welds, at least one of the two films being folded over the other at the end of the films, opposite the welds.
- the two films are folded back on themselves at the end of the films opposite the welds.
- the packaging comprises at least two sheets, a flexible film disposed between them and folded back on itself and welded to the sheets by the welds respectively and welded to itself and to the sheets by the welds.
- the fold formed by the film (s) is capable of being unfolded by introducing a straw between the films.
- the fold formed by the film (s) is not capable of being unfolded by the introduction of a straw.
- the packaging includes an additional seal between the sheets.
- the flexible film is made of PE, EVA, PP, OPP, PET, PA.
- the sheets are semi-rigid.
- the sheets and the flexible film have the following characteristics, with H the thickness in mm and E the equivalent module of the film in N.m ⁇ f 2 :
- the packaging is in the form of a Doypack or three seals.
- the invention also relates to a method of manufacturing a packaging according to the teaching of the invention, comprising the following steps: - insertion of a screen film between the films;
- the manufacturing process comprises the following steps:
- the screen film is made of PTFE or teflon-coated fabric.

- Figures 13a and 13b show a method of manufacturing this third package
- Figures 14a and 14b show the filling of this third package
- Figure 15 shows a variant of the first and second packages.
- a sachet 1 comprises two sheets 2, 3 facing each other. These sheets are made of material conventional in the art, in particular plastic such as PET, OPP, PA, etc. These two sheets are in particular semi-rigid, in the sense that they are liable to be deformed to accept dilation of the sachet while providing general support for the sachet.
- the thickness of these two sheets is conventional in the art, for example a thickness between 50 and 1000 ⁇ , and preferably between 60 and 250 ⁇ m.
- a flexible film 4 is arranged between these sheets 2 and 3, a flexible film 4 is arranged.
- This flexible film is made of a suitable material, in particular a plastic material.
- This film 4 may in particular be made of PE, or also of EVA, PP, OPP, PET, PA, etc. This film has a thickness of between 10 and 500 ⁇ m, and preferably between 30 and 100 ⁇ m.
- This film 4 is welded, over part of its length, to one end of the sheet 3 according to the weld 5 (which is represented here by hatching).
- This film is also welded, over part of its width to the sheet 2, in two welds 6a and 6b which define the width of the valve.
- These welds can be parallel or not, perpendicular or not to the weld 5.
- These welds 5 and 6a and 6b are arranged so that the weld 5 extends substantially between the welds 6a and 6b, which contributes to sealing.
- the weld 5 extends completely between the welds 6a and 6b.
- the welds 6a and 6b extend substantially over the width of the film strip 4, or even exceed this width.
- the film is in the form of a strip with a width of between 5 and 200 mm, and preferably between 10 and 50 mm.
- the length of the strip (in fact this time the width of the bag) is between 20 and 1500 mm, preferably between 50 and 400 mm.
- FIG. 2a shows the operation of the valve thus formed.
- the valve is in the open position (for example by introducing a straw).
- the film 4 is then in contact with the sheet 3.
- the internal pressures for example by the sole weight of the content
- Figure 2b illustrates this case; it is a section along the weld 6b in order to better indicate the phenomenon.
- the arrows indicate the thrust operated for example by a fluid in the sachet.
- FIG. 3 shows, in section, and illustrates a manufacturing diagram of the bag of Figure 1.
- the manufacturing uses a screen film which allows selective welding of the flexible film 4, either on the sheet 2, or on the sheet 3.
- the film 4 is welded in the form of a strip on the sheet 3 according to a weld 5.
- a film 7 is introduced forming a screen between the film strip 4 and the sheet 3. then affix sheet 2 to the previous structure, and place everything between two jaws a welding machine or solder bars.
- the jaw 8a is for example at room temperature while the jaw 8b is at a temperature sufficient to weld the film 4 to the sheet 2 according to the welds 6a and 6b. It is also possible to have a heated bar on a silicone counterpart.
- the two jaws are at the welding temperature, depending on the film and the rate.
- the welding temperature can be between 130 and 250 ° C, depending on the material to be welded.
- the screen film 7 is removed.
- the closure system shown in FIG. 1 is thus obtained.
- This screen film 7 is made of a material which is substantially insensitive to heat and which does not adhere to the film to be the soldering temperature. It may for example be made of PTFE, or of another material, such as teflon-coated fabric. We could also have a reverse sequence with the formation of welds 6a and 6b, insertion of a sheet 7 between these welds, then formation of the weld 5.
- sachets are the conventional sachets, such as "Doypack", 3-weld sachet, etc.
- the closure system can be placed at the center or on one side of the bag, as appropriate. In most cases, a straw or other similar instrument will be provided with the bag.
- This straw inserted between the sheets 2 and 3, is guided to the system described, spreads the sheets 2 and 3 at the weld 5, and is positioned naturally between the welds 6a and 6b.
- the walls formed on the one hand of the film 4 and on the other hand of the sheet 2 are pressed one on the other. A seal is thus obtained.
- This system can also include, as film 4 (or possibly as sheet 2), a film repositionable.
- films are known and include a support film 4a, an adhesive layer 4b and a welding layer 4c. the welding layer is welded, according to a bead, on the sheet 2 facing it (or on a welding layer affixed to said sheet 2). When tearing, the strip corresponding to the welded part is secured to the sheet 2, which discovers the adhesive. We can then, after the straw has been removed, apply pressure to completely close the system.
- Such repositionable films are described for example in WO-A-9719867. It is also possible to use, no longer a repositionable film, but a peelable film.
- Such films are known and, unlike the previous films, do not include a permanent adhesive layer, but an intermediate layer 4d. These films ensure, as before, the integrity of the bag before piercing with straw, but they are not repositionable.
- the film strip 4 can be welded to the sheet 2 according to an additional weld 6c, situated between the welds 6a and 6b, at the lower end of these (the weld 5 being at the upper end ).
- This welding 6c can be carried out at the same time as the welds 6a and 6b, or later, according to the conventional techniques indicated in the documents of the prior art referred to above.
- the bag provided with the type I opening system fills in a conventional manner, as illustrated in FIGS.
- the weld 5 extends, as shown, over the entire length of the sheet 3 (but one could only have weld 5 on the part between the welds 6a and 6b).
- the film 4 is only welded to the sheet 2 at the welds 6a and 6b, there is therefore a space between this film 4 and the sheet 2 in the area between the weld 6a and the rest from the sachet. There is therefore a filling area represented by the arrow.
- the weld 9 is welded, which extends from the weld 6a to the end of the bag, as shown in Figure 4b. This weld welds together the sheets 2 and 3 and the film 4.
- FIGs 5a and 5b show, in section, a second package.
- the film 4 is replaced by two films 10a and 10b.
- Each film 10a and 10b is welded to the sheets 2 and 3, respectively, according to welds 11a and 11b
- FIG. 6 represents a view in the closed state of these second packages.
- These welds 12a and 12b may be parallel or not, perpendicular or not to the welds 11a and 11ab.
- These welds 11a and 11b extend substantially between the welds 12a and 12b; preferably, the welds 11a and 11b extend completely between the welds 12a and 12b.
- the welds 12a and 12b extend substantially over the width of the film strips 10a and 10b, or even exceed this width.
- the valve defined by the welds 12a and 12b is then substantially sealed.
- FIG. 6a represents a view in the closed state of a variant of these second packages (in which the welds 11a and 11b have not been shown, and in which all the films and sheets have been shown, however).
- This variant makes it easier to open by increasing the blocking width of the fold; greater flexibility is thus obtained over the height of the fold.
- the welds 11a and 11b likewise extend here completely between the welds 12a and 12b.
- the position of the welds 12 'a and 12' b with respect to the welds 12a and 12b can vary within wide limits. In general, the spacing between these welds 12 'a and 12' b will represent between 5 and 50%, preferably between 10 and 35%, of the spacing between the welds 12a and 12b.
- the valve defined by the welds 12 'a and 12' b is here also substantially sealed. The other characteristics described with reference to FIG. 6 apply mutatis mutandis.
- FIGS. 7a and 7b show the valve closed, a fold of the film 10b covering the film 10a and ensuring one seal.
- the introduction for example of a straw between the sheets 2 and 3 causes one spacing of the films 10a and 10b and one obtains the opening of the valve as shown in FIG. 7b.
- Straw or other equivalent device such as a stopper or funnel
- the bag is empty. We then fill it, then remove the straw, which closes the bag.
- This system is particularly suitable when the fold (s) of the film (s) 10a and 10b extend over a large part of the width (taking account of the spacing of the welds). In this case, it is difficult for the user to separate the films 10a and 10b from the fold; the delivery of the empty sachet - in the open position - with the straw (or any other device) makes it a "trash can" or sachet with a riff which is very waterproof once the straw has been removed. This last variant is particularly suitable for dangerous products such as: frying oil, waste oil, solvents, residues and industrial sludge.
- a reversible or irreversible operation is obtained.
- reversible operation with opening / closing cycles, there is a spacing between the welds 12a (resp. 12 'a) and 12b (resp. 12' b) which is large compared to the height of the fold.
- irreversible operation the bag being delivered open, with only the possible closure, there is a spacing between the welds 12a (resp. 12 'a) and 12b (resp. 12' b) small compared to the height of the fold.
- the choice of the respective dimensions is within the reach of the skilled person.
- the characteristics of the films are substantially the same as for type I.
- the fold (s) represents (s), as a% of the spacing of the welds 12a (resp. 12 'a) and 12b (resp. 12 'b), between 5% and 50%. If you want an opening through a straw, the fold (s) represents (s) in general from 5 to 25%. If one wishes that the opening cannot be done, the fold (s) represents (s) in general, from 25 to 50%.
- FIGS. 8a and 8b illustrate the process for preparing sachets of the lia or Ilb type (we have chosen to represent the lia type here, first variant).
- FIG. 8a we see sheets 2 and 3, films 10a and 10b, as well as a screen film 7 of the same kind as that used for the manufacture of the type I sachet. Solder bars 13a and 13b heated to the soldering temperature are applied in order to obtain the welds 11a and 11b.
- the screen film 7 is removed, then as shown in FIG. 8b, vertical sealing bars 14a and 41b, heated to the welding temperature of the sheets 2 and 3 and films 10a and 10b are applied to obtain the welds 12a and 12b.
- the method further comprises the step of the welds 12 'a and 12' b.
- the welds 12 'a and 12' b it is possible to separate the sheets 2 and 3 films 10a and 10b to proceed 'to the weld.
- Figures 9a and 9b show the filling area.
- the closure system is shown on one side of the bag.
- the welds 11a and 11b on the one hand, and 12a and 12b on the other hand, are already affixed.
- Figure 9a there is shown the free space between the film 10a and the sheet 2, which allows filling schematically by the arrow.
- the weld 15 is welded which extends from the weld 12a to the edge of the bag, as shown in FIG. 9b. This weld welds together the sheets 2 and 3 and the films 10a and 10b.
- Figure 10 shows a third package (hereinafter type III).
- the film 16 in the form of a strip is folded back on itself and welded to the sheets 2 and 3 by the welds 17a and 17b.
- This film 16 is similar in nature to that of films 10a, 10b and 4.
- FIG. 11 represents a side view, in which the welds 18a and 18b are visible. These welds can be parallel or not, perpendicular or not to the previous welds.
- the welds 17a and 17b extend substantially between the welds 18a and 18b, preferably completely between them.
- the welds 18a and 18b extend substantially over the width of the folded film strip 16, or even exceed this width.
- the valve thus formed is called type III. Unlike types I and lia and Ilb, the film 16, in the original state, does not allow the passage of a straw. It is necessary to pierce the flexible film 16.
- the piercing tool is preferably a piercing plug 19, as shown in FIG. 12.
- the piercing tool can also be a straw.
- the piercing plug 19 shown in FIG. 12 comprises a body 20 traversed by a channel 21.
- the piercing plug also includes a piercing tube 22.
- the body 20 advantageously comprises a thread or splines, which will make it possible to make this plug integral flexible film 16.
- This film 16 is preferably elastic in order to obtain a diaphragm effect enclosing the plug.
- this plug 19 can be provided with a cap 23 which can be screwed. This cap can be simple, with a spout, resealable, invidable, with childproof lock, etc.
- FIG. 13a represents the first step of a manufacturing scheme for the type III sachet.
- the manufacturing uses a screen film 7.
- the film 16 is welded to the sheets 2 and 3 according to the welds 17a and 17b, the film 7 being inserted into the fold of the film 16.
- Weld bars 24a and 24b weld according to the welds 17a and 17b.
- the screen film 7 is then removed, and weld bars 25a and 25b weld together the sheets 2 and 3 and the folded film 16 according to the welds 18a and 18b.
- Figures 14a and 14b show the filling.
- the closure system is shown on one side of the bag.
- the welds 17a and 17b on the one hand, and 18a and 18b on the other hand, are already affixed.
- Figure 14a there is shown the free space between the film 16 (folded) and the sheet 2, which allows filling schematically by the arrow.
- the weld 26 is welded which extends from the weld 18a to the edge of the bag, as shown in FIG. 14b. This weld welds together the sheets 2 and 3 and the folded film 16.
- Figure 15 shows a package common to types I and Ila / llb.
- the sheets 2 and 3 are moreover welded along an additional line 27, affixed to an extension of the sheets 2 and 3.
- a weakening line or a simple marking 28 can be affixed under the weld 27 in order to encourage the user to cut the bag according to this marking.
- the additional weld ensures total tightness.
- the packaging by its variants of type I, II (Ila / llb) and III therefore offers numerous advantages, by the association of two semi-rigid sheets 2 and 3 forming the body of the sachet and one (two) film ( s) flexible 4; 10a, 10b; 16.
- the characteristics of the sheets and films are common between all the packages and the description given with reference to FIG. 1 applies mutatis mutandis to the other variants.
- the other characteristics are common to the various variants.
- the bag is: waterproof by film / film contact welding by film folding by film / insert contact - by ZIP lock system (two profiles, generally extruded, which cooperate by fitting one inside the other) by peelable / repositionable film (type I ) openable and reclosable - by attached plug (type III) by mechanical operation of the sealing system (type I, II) tamper evident attached plug (type III) - film / sheet or sheet / sheet welding.
- the sachet also has the advantage of being flat (before filling), which facilitates handling and reduces the packaging volumes of the sachets.
- the bag has an overall thickness generally less than 2 mm, preferably less than 500 ⁇ m.
