Definitions

  • the present invention relates to a sachet for the packaging of liquid formed using material film plastic, including a liquid-tight enclosure and a pocket, adjacent to this enclosure, in which is housed a liquid sampling conduit, means being arranged to access the interior of said pocket, a opening being formed through part of the wall of this pocket, adjacent to said enclosure, to allow said sampling conduit entering tightly into said enclosure.
  • This invention also relates to a process for making sachets and packaging liquid continuously in these sachets.
  • a sachet for the packaging of liquid comprising a integrated valve to control the outlet of the liquid and susceptible to be able to be manufactured continuously from thermoplastic film.
  • the preamble of claim 1 is based on this state of the art.
  • the disadvantage of this system is that removing the straw, the latter brings out the liquid which is found in the valve channel, gradually dirtying the outside of the bag.
  • the object of the present invention is precisely to provide a solution to the problem of sealing, as well as that of the manufacture of sachets and the packaging of liquid continuously in such sachets, allowing in particular to use known machine concepts, even if they are nevertheless called upon to undergo transformation substantial to adapt to manufacturing and packaging of these sachets.
  • the present invention has first of all for object a sachet for the packaging of liquid of the type the aforementioned as defined by claim 1.
  • This element tubular of decreasing section is obtained by stretching with a plastic film and thus allows to retain the elasticity of the film, guaranteeing an effective seal. It's about more than a very simple solution, perfectly adapted to the product for which it is intended.
  • the wall of the pocket containing said sampling line is integral with a cut tongue in a layer of film intended to form the enclosure waterproof.
  • This tab guarantees inviolability access to the straw used to distribute the liquid.
  • the opening formed at the end of the tubular element forming a seal communicates with one end of a valve channel between this opening and inside the waterproof enclosure, the pocket of the bag being formed between a first layer of film forming one of the walls of said channel and a second layer of film significantly narrower than the first layer and secured to the pocket opening tab.
  • this pocket can however be formed in the fold of a film folded back on itself.
  • this fold may lie adjacent to one end of the canal controlling the liquid flow and the tubular element forming seal may extend over part of it channel.
  • This invention also relates to a method of manufacture of sachets and liquid packaging in continuous in these sachets according to claim 9.
  • One of the advantages of this process is to allow the filling of sachets and placing straws laterally, one longitudinal edges of the strip material intended to form one of the edges of these sachets remaining open until filling time. Because of this, the straw can be introduced laterally in the axis of the joint and the channel valve when this channel exists, and a supply conduit liquid can pass between the walls of the sachet, along from its edge coinciding with the longitudinal edge of the material in a band. The welding of this longitudinal edge is carried out as the strip material advances, just before filling.
  • the process takes place in two separate phases, one consisting of forming a continuous band of sachet blanks, the second of which is to form the tubular joint, to introduce the sampling conduit and to condition the liquid in the enclosure.
  • the advantage of this embodiment is to allow the manufacture of blanks and liquid packaging in two units of separate productions, the conditioner of the product not being not necessarily capable of solving the problems posed by manufacture of such a bag.
  • the conditioner of the liquid in the packaging can then use the draft thus produced as the simple sheets or films used for packaging liquid in cartons, sachets or bricks, in carrying out the packaging using the usual machines, so that to condition the liquid he wants sell in sachets according to the invention, in particular the valve bags, the liquid conditioner, replace simple extruded films or sheet materials usual, by the blanks of sachets according to the present invention.
  • One of the main advantages of the enclosure the invention is to have a sealing of the valve channel which allows, by piercing this lid not by cutting, but by punctual deformation of the cover in the direction of the valve channel until it breaks, to obtain an annular seal slightly tapered which guarantees elastic tightening straw, ensuring a seal that avoids that liquid in the valve channel does not get out escapes.
  • the pocket intended to accommodate the curved part of the straw located outside the valve channel is performed after the introduction of straw into the entrance to this canal, so that the straw does not pull on the side welds from the pocket.
  • Figures 1 and 2 show three sheets 1, 2, 3 overlapping sheet material, the third of which is width significantly smaller than the first two.
  • the first sheet 1 which is intended to form the wall of a waterproof enclosure, in this example, a sachet for packaging of a liquid, especially a drink, is preferably made of a plastic sheet multilayer, as usually used for packaging of food products.
  • the different layers of these multilayer sheets can be formed of different plastics or the same material, this which allows them to be recycled.
  • the sachet object of the present invention is not limited to the packaging of drinks, but can be used for any type of liquid.
  • the second sheet 2 is a plastic film extruded, especially polyethylene, as well as the third sheet 3. It should also be specified here that, even if sheets 2 and 3 have been shown to be initially two separate sheets, they could also form initially a common sheet, folded around an axis longitudinal to that of this strip sheet, to form then the two sheets 2 and 3 of different widths shown in Figures 1 and 2.
  • sheets 2 and 3 could be from a tubular film, put under slight overpressure internal, the superimposed layers being obtained in gradually flattening the tube and folding longitudinally and gradually inward, a portion of this tube. In this way, we obtain four superimposed layers, two of which are narrower than the other two, connected to each other, as illustrated in Figure 8, but without requiring welding between them.
  • the first step in manufacturing the process consists, in this example, to cut a tab 4 in the first sheet 1 intended to form the wall of the sachet.
  • This tab 4 remains attached to sheet 1 by one end.
  • the cutting tools are symbolized by the rectangles 5 and 6 of figure 2.
  • Tools for the realization of this hole 7 are symbolized by a conical punch 8 and a matrix 9 in Figure 2. How to do this hole 7 is important. It is not a question of cutting this hole 7, but occasionally stretch the film using the punch 8 in the housing formed in the matrix 9, until rupture of the film 3.
  • this weld 10 is of particular interest. It makes it possible to join together the three sheets of film 1, 2, 3 together, of so there can no longer be a displacement between they. We know that plastics are likely to creep as a result of traction on them. These leaves also undergo variations of significant dimension following variations in temperature, as well as variations in humidity. When working like here on a strip material up to several hundred in length meters, these variations can result in the long run by significant shifts. By joining together the films at the beginning of the manufacturing process, it is guaranteed that the operations made later on the different sheets on will be in relative positions which can no longer vary in troublesome proportions.
  • the next step consists of folding sheets 2 and 3 back on themselves the direction of the width of the bands, around two axes of longitudinal folding to form two parallel folds 2a, 3a.
  • folding these sheets 2, 3 onto themselves the edges longitudinal of these sheets 2 and 3 are aligned on the longitudinal left edge, also corresponding to one of the edges of sheet 1 forming the wall of the bag.
  • these folded sheets 2, 3 only overlap in the part of the width of these bands adjacent to the overlapping edges of these bands.
  • Sheet 1 meanwhile, is moved away from sheet 2 to allow access to the latter.
  • two non-converging welding lines 11 are made in the part of the folded sheet 2 which does not overlap with the sheet 3. These welding lines 11 form the edges of a channel 12, between the two folded films of the sheet 2, which is intended to form the valve 12a controlling the distribution of the liquid packaged in the sachet. Simultaneously, the two longitudinal edges of the folded parts film sheets 2 and 3 are attached to each other by a longitudinal weld 13. As illustrated by Figure 8, a separator 14 is inserted between the two parts folded back from sheet 3 to maintain a longitudinal opening allowing free access to the interior of the pocket 15 formed between the two films of the folded sheet 3. Tools for welding the edges 11 of the channel 12 are symbolized in FIG. 8 by two rectangles 16 and 17.
  • Figures 9 and 10 show the cutout 18 of the two superimposed films resulting from the folding of sheet 2, carried out at using two tools symbolized by rectangles 19 and 20 in Figure 10.
  • This division has the shape of a U whose the two parallel branches are asymmetrical. Branch transverse of this cutout 18 is located near the end of the channel 12 adjacent to the fold of the sheet 2. This cutting 18 is intended to make the channel 12 communicate with the inside of the bag.
  • the asymmetry of the parallel branches of this cutout 18 which extend on either side of the part of the channel 12 forming the valve 12a is intended for improve its functioning, in cooperation with narrowing asymmetrical section of the channel 12.
  • This stage corresponds to the end of the manufacturing of the blank from the sachet. That is, up to this point in the manufacturing, the blank obtained can be rewound to be transported to another manufacturer for packaging liquid in future sachets that he will finish by conditioning the liquid, as we will explain. Well understood, this is only a possibility to which the invention is obviously not limited. We can indeed perform online packaging following the steps in manufacturing process described so far.
  • Figures 11 and 12 show the installation of straw 21 between the two folded film portions of the sheet 3, to the first part of channel 12 through the opening 7 formed at the end of the seal tubular 7a which has been discussed previously.
  • hole 7 could be made at using the straw 21 itself or a separate tool, just before the introduction of straw 21 and not at during the manufacturing of the blank, as described above.
  • the hole 7 could also be primed during the manufacturing of the blank, to facilitate drilling with straw 21.
  • the end of the straw 21 has an annular bulge 21a whose purpose is to provide resistance when the straw 21 is removed from channel 12 and that this bulge arrives at the level of the opening 7.
  • clamps 22 arranged on each side of the straw 21 serve to retain the sachet blanks during the introduction of straw 21.
  • the annular bulge 21a of the straw 21 can advantageously be replaced by a deformation of the end of the straw that is turned outwards over a certain length, advantageously a few mm, just like you do with a sock. This reversal can easily be obtained hot.
  • the returned part forms a annular space in which the tubular seal 7a can engage when trying to take out the straw 21 of this joint, thus forming a stop.
  • the last step before packaging the liquid is to connect the end of the channel 12 adjacent to the fold 3a of the third sheet of film 3, at the longitudinal edge where all the longitudinal edges of the sheets are superimposed 1, 2 and 3 by two parallel welds 24, 25.
  • the second longitudinal edge of the first sheet 1 intended to form the wall of the bag 30 will also be fixed along this edge longitudinal, when conditioning the liquid, as will see it below.
  • These two welds 24 and 25 divide the pocket 15 formed between the two adjacent films of the sheet 3 folded, into three compartments 31, 32, 33, the last 33 contains the folded part of the straw 21.
  • These welds 24 and 25 join the two sheets together folded 2 and 3 with sheet 1 not yet folded, that is to say once bag 30 is finished, both sheets folded 2, 3 will be integral with the same internal face of this bag 30.
  • FIGs 15 and 16 show the finished bag 30.
  • This sachet is finished during packaging liquid, it consists of folding longitudinally sheet 1 around the other two sheets 2 and 3 already folded. Then the sheets 1, 2 and 3 are welded longitudinally by a weld 26 joining the longitudinal edges of the six layers of the three folded sheets 1, 2 and 3 and by another longitudinal weld 27 formed along the adjacent folds of the two folded sheets 1 and 2.
  • a third transverse weld 28 is provided between the welds longitudinal 26 and 27. This weld 28 is intended for form the bottom of the bag 30 which is then filled by the fourth side remained open for this purpose, after which the sachet is closed by a second transverse seal 29.
  • the bag 30 thus obtained, is separated from the strip material to which it was attached so far, cutting this material into strips at the flush with the welds 28 and 29.
  • the bag 30 has two sealing barriers.
  • One is the valve 12a formed by the part of the channel 12 located between the end of this channel 12 adjacent to the cutout 18 and the throttles asymmetrical leading to part of this channel of enlarged section.
  • Another is formed between straw 21 and the tubular joint 7a.
  • the seal 7a which encloses the straw 21 around the opening 7 formed through the sheet 3. From this done, the outside of the bag always stays clean and dry.
  • the seal 7a in cooperation with the annular bulge 21a of straw 21 also serves to avoid accidental removal of the straw 21 from channel 12. This is why it can be useful to locally reinforce the portion of film 3 forming this seal 7a, as previously mentioned.
  • the closed compartments 31, 32 located on either side on the other side of compartment 33 containing the curved part of straw 21, are isolated from the main enclosure of the bag 30 intended to contain the liquid, formed between the two folded parts of sheet 1. These compartments could be used to receive all kinds of items, objects, surprises, advertisements, games or items games etc. which can be inserted during the operation for conditioning the liquid in the main enclosure of the bag 30.
  • separators are interposed in the corresponding parts of the trajectory film strip (s).
  • the separators will be animated by alternative movements in the direction of travel of these bands to follow the movement of the electrodes welding or cutting punches.
  • valves Since it is possible to make the sachets provided with valves according to the invention, from one, two or three sheets, one of which may be tubular, it may be preferable to start the process by folding the sheets to bring them, before welding or cutting, in the position illustrated in figure 6, after which we start the cutting and welding operations in the order described above.
  • welding 10 superimposed on tab 4 and around the end 4a of this tongue 4 can preferably be produced, simultaneously with the welding 11 of the channel 12 of the valve illustrated by figure 7.
  • the drilling of the opening to allow the straw 21 to access the channel 12 of the valve in a sealed manner, produced in the fold 3a of sheet 3, can be done during the operation of packaging of the liquid in the sachet.
  • FIGS. 17 to 24 differs from that previously described essentially by the fact that the pocket 15 is no longer formed inside a folded sheet, as before, but between a sheet 35 and a sheet 36, between which the channel 12 is formed of the valve 12a by the two non-convergent welds 11.
  • this channel 12 is preferably not formed by a folded sheet 3 around a longitudinal axis of the strip film, but between two sheets 36, 37.
  • the internal longitudinal edge of the sheet 35 is welded along line 38 to sheet 36 forming one of the walls of the channel 12 ( Figures 17 and 18).
  • the wall of the bag is preferably formed by a single sheet 1 intended to be folded longitudinally later.
  • a tab 4 is cut from this sheet 1 (figures 17, 18) by cutting tools 39, 40 and this tongue 4 is welded to the sheet 35 by a weld 10 except from its end 4a which is in the zone 10a not welded (FIG. 19, 20), by welding tools 41, 42.
  • this weld 10 extends all around tab 4 to isolate it from the liquid inside from the sachet.
  • the sheet 1 forming the wall of the bag is folded longitudinally in half to bring its two edges to join, these edges being aligned with one of the edges of each film ribbon 35, 36 and 37.
  • This step marks the last of the manufacturing process of the sachet blank according to the present invention. Two possibilities are then possible, either the strip along which one succeeds a plurality of regularly spaced blanks continues on a liquid conditioning unit, i.e. this strip of blanks is wound up to be transported to a unit separate packaging.
  • Figures 23 and 24 illustrate the first step in conditioning process, the others will not described since it suffices to refer to the form previous execution in which the subsequent steps relating to the conditioning process are the same as for this second embodiment.
  • the tubular joint 7a is formed in the folded sheet 3, at the place of its longitudinal fold, in this embodiment, the tubular joint 7a is formed by piercing the film 36 forming a wall of the channel 12 and of the pocket 15, adjacent to the film 35 forming the other wall of this pocket 15, using of a tool 42.
  • the bag with a valve 12a constitutes the form preferred embodiment of the invention.
  • this valve could be deleted as long as before its first use, the delivery duct 21 of the bag is closed by a removable shutter such as a plug, then only after first use, the sachet either or capped, or constantly maintained in a position where the outlet opening of the distribution duct 21 is not below the liquid level in the bag.
