Definitions
- the present invention relates to an etan ⁇ che enclosure for the packaging of a liquid, comprising a sheet fixed to the internal face of a wall of the enclosure by a tight connection surrounding an area of this sheet. thus isolating from the interior of the enclosure, the rupture of this sheet in said zone thus isolated allowing access to the interior of the enclosure.
- a sheet fixed to the internal face of a wall of the enclosure by a tight connection surrounding an area of this sheet thus isolating from the interior of the enclosure, the rupture of this sheet in said zone thus isolated allowing access to the interior of the enclosure.
- watertight enclosures with a flexible or more or less solid wall, pierced with an opening closed by a membrane fixed against its internal face, used for packaging liquid. To access the interior of the enclosure, it suffices to perforate the membrane.
- the membrane is pierced with a straw which is then used to suck up the liquid.
- the enclosure is a sachet with a flexible wall in particular, the pressure necessary for the perforation of the membrane is transmitted to the wall of the sachet thus creating a momentary overpressure on its liquid content when it is opened, so that pressurized liquid can come out of the bag.
- DE-A1-41 15 000 shows a tubular sachet whose marginal parts adjacent to the longitudinal edges overlap, each of these edges being welded to the adjacent face.
- An opening is made in the marginal part of the underlying longitudinal edge, while a tongue, offset in relation to the opening, is cut in the marginal part of the longitudinal edge which covers this underlying part.
- a transverse weld extends between the two welded longitudinal edges. This transverse weld passes between the opening and the tongue, so that a tight barrier isolates this opening from the cut-out tongue.
- To open the bag simply pull on this tab to tear the portion of the wall of the bag which covers one opening. To access the opening, you must first break the transverse weld between the opening of the tab by pulling on the latter.
- This rupture of this transverse weld requires significant effort. It is also difficult to control. Therefore, it risks either causing the rupture of the tongue, or a tearing of the longitudinal welds, causing the disintegration of the bag. Independently of these risks, the sealed overlapping area where the opening is located, located between the longitudinal seams, the transverse weld and a weld closing one end of the sachet, is in communication with the interior of the sachet. Consequently, liquid can filter in this area. When the sachet is opened, this liquid will flow onto the outside of the sachet and get it dirty.
- Leak-proof sachets are also known which are provided with a valve, at least part of which is situated inside the bag and is formed between two flexible sheets, passing through part of the bag and fixed in a sealed manner between the edges of the bag. These sheets are joined in two non-converging lines to form between them a channel by separation of said sheets from one another, allowing the passage of a fluid between the inside and the outside of the sa ⁇ chet, the flexible sheets being intended to be pressed against each other as soon as one ceases to apply a force to them to separate them, thus preventing said fluid from leaving the sachet.
- valve of these sealed bags is normally formed by a conduit open at its two ends, so that it offers no guarantee to the user with regard to the use of this bag prior to its purchase. . Besides that the buyer does not therefore have the guarantee that the sachet still contains the volume of products initially packaged- Nor does it have any guarantee as to the hygienic conditions of the product thus packaged.
- the channel forming the val ⁇ ve between the two flexible sheets must have a sufficient length so as to ensure effective closing.
- the length of the channel has been increased by providing a duct which is oblique to the main axis of the bag, so that the length of this duct is increased without increasing in the same proportion.
- ⁇ the length of the flexible sheets extending in the sa ⁇ chet. The fact remains that the surface of the flexible sheets used is significantly larger than the area occupied by the channel.
- one of the aims of the present invention is an optimum use of the volume of the sachet.
- the upper part of the sachet is left open to allow filling.
- the filling level cannot be very high in this case, otherwise the liquid overflows from the bag when welding the upper edge.
- the filling rate of the sachet with the liquid is not very high. It is certainly possible to fill the sachet through the valve channel, but liquid will remain in this channel which is not acceptable, the channel having to remain perfectly clean until its first use.
- the object of the present invention is to remedy, at least in part, the above-mentioned drawbacks.
- the present invention relates to a sealed enclosure in which a tongue, intended for the opening of said enclosure, is formed in the portion of its wall adjacent to a zone of the sheet fixed to the interior of the enclosure, surrounded by a tight connection re ⁇ binding this sheet to the wall of the enclosure, one end of this tongue being free and serving as a gripping means, while another part of this tongue is fixed to said sheet, thus making it possible to break said sheet by pulling the tongue and thus to access the interior. of the enclosure.
- This invention also relates to a sachet étan ⁇ che provided with a valve, of the aforementioned type.
- a second flexible sheet is joined to the first sheet, also flexible, along two non-convergent connecting lines extending between two parts distant from the assembled edges of the walls of the enclosure to form a conduit between these sheets, in the part extending between the connecting lines, at least one of said sheets having a cut between said non-convergent connecting lines, at a distance from said sealed connection between said first sheet and the wall of the enclosure to communicate said conduit with the interior of the enclosure, the parts of these sheets situated between said connecting lines being intended to be pressed against each other as soon as they are no longer applied to them a force to separate them, thus preventing said fluid from leaving the enclosure after having provided an opening in said first sheet using said tab.
- Another object of the invention is a bag or a sealed enclosure provided with a valve, of the aforementioned type, in which a second channel is formed between said flexible sheets and has an external end adjacent to an edge of said bag and the another in communication with the interior of this sachet.
- This invention also relates to a method of packaging a liquid in a bag or an enclosure comprising said second channel, according to which the sa ⁇ chet is formed as well as the two channels, the external end of said second is left open at least channel adjacent to the edge of said bag, introducing said liquid through this second channel and closing said outer end of the second channel.
- This solution therefore does not increase production costs.
- existing production lines can continue to be used with very slight modifications for a not insignificant advantage in terms of product.

- Figure 1 illustrates four strips 1, 2, 3, 4 of monolayer or multilayer thermoplastic film such as polysty ⁇ reene, polypropylene, polyethylene or polyamide, endless, used for the manufacture of the sealed bag, object of the invention.
- the strips 1 and 4 which are wider, are intended to form the walls of the bag, while the strips 2 and 3 are used to make the valve.
- the film thickness of the strips 2 and 3 of the order of 40 ⁇ m is less than that of the film of strips 1 and 4 of the order of 100 ⁇ m, to make strips 2 and 3 more flexible to facilitate closing of the valve.
- the first operation is carried out on sheet 1 and consists in pre-cutting tabs 5 at regular intervals.
- Each tab 5 is intended to be located near one of the corners of the bag.
- the end of this tongue 5 is cut while its parallel edges are precut so that before use, the tongue
- the second operation (fig. 3) consists in depositing a rectangle of ink or heat-resistant varnish 6 on the sheet 2, at regular intervals, corresponding to the intervals between the tongues 5.
- the third operation consists in welding the sheets 2 and 3 along two parallel lines 7 and 8 (fig. 4) providing a channel 10 between them, the flexible walls of which are normally contiguous, but are capable of being spread apart. on the other, thus constituting the valve controlling the distribution of the conditioned liquid.
- These welds 7 and 8 become thinner at the place where the heat-resistant varnish is located 6.
- two parallel cuts 9 are made in the welds 7 and 8 and a transverse section 9a connects the parallel cutouts 9, thus met ⁇ the channel 10 in communication with the outside.
- a transverse section 9a connects the parallel cutouts 9, thus met ⁇ the channel 10 in communication with the outside.
- the two strips 2 and 3 are welded to the strip 1 according to a weld 11 which extends along the outer edge of the strips 2 and 3 and in the vicinity of the adjacent edge of the strip 1.
- a weld 12 is also produced which surrounds the long sides of the rectangle of heat-resistant varnish 6 deposited on the sheet 2 and which cuts this rectangle 6 across its width, so as not to weld the sheets 2 and 3 together at the location of the channel 10.
- the strips 1, 2, 3 of the fourth strip 4 are covered and three welds 14a, 14b, 14c are made, forming three sides of the sealed bag 15, one 14b along the one of the edges of the bands 1 and 4 and the other two 14a, 14c transversely to these bands.
- the fourth side, adjacent to the other edge of the strips 1 and 4 remains open to allow subsequent filling of the waterproof bag 15.
- the last step consists in separating the sealed bags from each other between two adjacent welds 14a, 14c.
- the sealed bag 15 illustrated in FIG. 7 is ready to receive the liquid to be conditioned, after which the fourth side will be sealed, enclosing the liquid in a sealed manner.
- FIG. 7 The content of such a sachet cannot be consumed from the hermetically sealed sachet, following the filling made from the sachet illustrated in FIG. 7. Indeed, no opening then allows access to the interior. of the sealed bag, so that the inviolability of this bag is guaranteed and verifiable and the preservation of hygienic packaging conditions is ensured insofar as no opening allows access to the interior of the bag.
- Figures 10 to 12 show how it is possible to access the contents of the sachet using a straw or any conduit 17 for passing the liquid from the inside to the outside. It suffices to detach the tongue 5 and pull it towards the edge 14c of the bag 15.
- the start of the channel 10 has an abrupt widening 10a intended to make it possible to accommodate and maintain a folded end 17a of the straw 17 when it is desired to interrupt the consumption of the liquid.
- the bottom of the enlargement 10a also forms a stop for the end 17a of the straw 17 preventing this straw from sinking into the channel 10 to a depth where it would open the valve formed by this channel 10.
- the edge of the tongue 5 adjoining the wall 1 of the sealed bag 15 is adjacent to the weld 14c, so that this weld limits the tearing length of the tongue 5.
- FIGS. 13 to 15 consists in adding to the part of the bag 15 provided with the valve, a strip of a more rigid material, such as a strip of thicker material (of the order of 200-250 ⁇ m) 18, such as a thermoplastic film of the same kind as that of sheets 1 to 4.
- This strip 18 is provided with parallel folding grooves 19 which are obtained by compression.
- This strip 18 is fixed to the bag by welding it to the tongue 5, itself welded along the rectangle 13 to the sheet 2, as illustrated by FIGS. 5 to 7.
- the tongue 5 By pulling on the strip 18, the tongue 5 is pulled and the wall of the channel 10 is torn, thus opening the valve.
- the strip 18 is then stained from the tongue 5, the welding between this strip 18 and this tongue being chosen for of- fry a lower tensile strength than the weld 13 between the tongue 5 and the sheet 2.
- the strip 18 Once the strip 18 is detached, it is folded according to the fold grooves 19 to form a conduit playing either the role of straw or that of the spout according to the given shape and one is produced in the opening 16 as before (FIG. 15).
- FIGS. 16 to 19 presents, in addition to the channel 10 serving as a valve and conduit for distributing the liquid conditioned in the sachet, a channel 20 intended only for filling the sachet.
- the operations for manufacturing the sachet according to this variant are the same as those described for the previous embodiment, so that these operations will be described more succinctly for this variant.
- a pre-cutting of the opening tab 5 is made in the sheet 1 used to form one of the walls of the bag.
- a layer of savings varnish 6 is deposited on one of the sheets 2, intended to form the valve.
- the layer of sparing varnish 6 also extends over a portion 6a of the width of the weld 14a forming the periphery of the sachet, and over a certain length of this weld 14a, for the purpose that will be explained later.
- the sheets 2 and 3 are welded along the lines 7, 8 to form the channel 10 and the Vietnameseu ⁇ page 9 to put this channel in communication with the interior of the bag.
- the channel 20 it is formed between the weld 8 and a weld 21 which extends along the internal edge of the sheets 2 and 3.
- the sheets 2 and 3 are assembled to the sheet 1 using a weld 22 (fig. 17) which has an opening 22a superimposed on the head 5a of the tongue 5.
- This weld as before, assembles the rest of the tongue 5 to the wall 1 of the bag, the varnish spares 6 preventing the welding of the two walls 2 and 3 at the location of the channel 10 between them.
- the sheet 4 is superimposed on the sheets 1, 2 and 3 and they are welded edge to edge to form the sealed bag. During this operation, we make sure to superimpose the welding of the edge of the bag to the zone 6a covered with sparing varnish, which has the effect of leaving this part of the bag open.
- the following operation consists in introducing into the ca ⁇ nal 10 a folded straw 17 and into the channel 20 a filling cannula 23. Once the filling is completed, the ends of the channels 10 and 20 are closed by welding the edge of the sa ⁇ chet in the part of the width left free by the savings ver ⁇ nis 6a as illustrated in FIG. 19.
- This sachet can then be used like the sachet described above, by tearing off the tab 5 giving access to the straw 17 and to the distribution channel 10.
- the sealed enclosure illustrated by FIGS. 20 to 23 is shown empty and comprises two sheets 1, 32 of monolayer or multilayer plastic material such as polystyrene, polypropylene, polyethylene or polyamide, originating from two endless bands of a thickness of the order of lOO ⁇ m, welded edge to edge over their entire periphery 33, then cut transversely to the direction of travel of the strips, once the enclosure is finished.
- This sheet 1 has a precut tab 5, one end of which is a 5a, constitutes a gripping element of this tab 5, while the body 5b of this tab is welded to band 34.
- the body 5b By grasping this end 5a, in order to separate the lan ⁇ perch 5 from the sheet 1 in which it is cut, the body 5b, welded to the strip 34, tears the latter as illustrated by FIGS. 21 and 23, providing a opening 36 which gives access to the interior of the enclosure and then allows the liquid which is conditioned there to escape.
- the opening 36 When it is a drink, one can introduce a straw through the opening 36 and suck the liquid.
- the essential advantage of the present invention is linked to sealed enclosures with a flexible wall of the sa ⁇ chet type, the invention could also apply to other types of sealed enclosures for the packaging of liquids.
- the invention is in no way limited to the fact that the membrane fixed against the internal face of the pa ⁇ king of the enclosure is constituted by a strip crossing the length or the width of the enclosure, the use of 'A strip of this type is advantageous because it allows the enclosure according to the invention to be produced continuously from strip materials.
- the entire surface of the strip 34 need not necessarily be welded to the internal face of the wall 1 of the bag.
- FIGS 24 and 25 illustrate not only a variant of the process of Figures 1 to 7, but also a variant of the valve formed between the sheets 2 and 3 available. between the sheets 1 and 4 forming the sachet. In this variant, the sheet 1 has not been shown, but it obviously exists.
- section a-a in FIG. 25 corresponds to welding 7 ′, 8 ′ delimiting the channel 10 ′ of the valve.
- this channel is not with parallel edges and the aims and functions of the sectional variations thus given to channel 10 will be explained below.
- a transverse weld 42 is provided near one end of the channel 10 ', the usefulness of this weld will be explained later.
- the following operation consists in cutting 9 ′, 9 ′ intended to make this channel 10 ′ communicate with the outside.
- This cutout 9 ' has the shape of a U, the two branches of which are not of the same length.
- this asymmetry of the branches of the U-shaped cut 9 ' coincides with the asymmetry of the narrowing situated in the middle of the channel 10'.
- This asymmetry of the channel 10 'and of the cut 9' has shown that it makes it possible to improve the closing of the valve, that is to say of the part of the channel 10 'extending from the asymmetric narrowing of this channel and the cutout 9 ', 9'a.
- a straw 17 ′ is introduced into the channel 10 ′.
- the diameter of this straw is such that it corresponds substantially to the narrowing formed at the entrance to the channel 10 '. Therefore a seal is obtained between the straw and the inlet end of the channel 10 ', so that the liquid which may have flowed between the channel 10' and the straw 17 'during ou ⁇ the valve is prevented from leaving this channel 10 '.
- the end of the straw 17 'introduced into the channel 10' has a bulge 17'a which serves to prevent the straw 17 'from coming out of the channel 10', this bulge abutting against the narrowing located at the entrance to the 10 'canal.
- transverse weld 42 limits the movement of the straw 17 'in the conduit 10'.
- the operation illustrated by the section dd is carried out in parallel on the sheet 4 forming one of the walls of the sa ⁇ chet. It consists of cutting the tongue 5.
- the sheet 4 joins the other two sheets 2,3 and a non-weldable sheet (not shown) is interposed between the straw and the sheet 3 already attached to sheet 4.
- the welding 40 carried out in operation ee only welds together sheets 3 and 4 and the opening 40a serves to leave the end 5a of the tongue 5 free, the rest of this tab being welded to the sheet 4.
- the last operation consists in carrying out two weld points 41 between the welds 7 ', 8' forming the channel 10 'and the wall 4 of the bag as well as two parallel weld lines 43, the spacing of which corresponds to that of the welds ⁇ res 7 ', 8' of channel 10 '.
- These welds 43 connect the valve formed by the channel 10 'to the opposite edge of the sheets 2, 3 and 4. It 43 thus delimits the width of the housing receiving the folded part of the straw 17'.
- the welding points 41 serve to prevent the sheets 2, 3 from following the straw 17 'when the bulge 17' a is brought back into bu ⁇ ted against the narrowing situated at the entrance of the channel 10 ', allowing closing the valve.
