Definitions

  • the present invention relates to a sealed enclosure equipped with a valve located inside of it and formed between two flexible sheets extending from an edge to a other of the enclosure and joined along two connecting lines non converging to delimit a conduit between them spacing of said flexible sheets from one another,
  • the channel forming the valve of these sealed bags is normally open at both ends, so that it does not offer any guarantee to the consumer with regard to a use of this sachet prior to its purchase. Outraged that the purchaser therefore has no guarantee that the sachet still contains the volume of product initially packaged, he has no further guarantee as to the conditions hygiene of the product thus packaged.
  • the inventors of the present invention have found the means of simultaneously solving the two problems, by forming a extending channel, like the leaves in which it is formed, from one edge to another of the enclosure waterproof, which allows the use of sheets whose width does not exceed much that of this channel.
  • Such a channel if it allows optimal use the sheets extending through the sealed enclosure while reaching a sufficient length, does not communicate however neither with the interior nor with the exterior of the enclosure and at this stage forms a simple hermetically sealed space both inside and out the outside of the enclosure, unlike the oblique channel valves according to the state of the art.
  • a cut is made through at least one of the sheets in which the channel is formed, between the non-converging connecting lines delimiting this channel, the thus putting in communication with the outside.
  • a tongue has been cut from the wall of the enclosure, a portion of this tab being fixed to the adjacent sheet used to form the channel, between the two connecting lines not converging at a location distant from the aforementioned cut. The end of this tab is left free to grab it. A tight connection is formed around the tongue, between the enclosure wall and the sheet adjacent.
  • one of the objects of the present invention is an optimal use of the volume of the sachet.
  • 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 by the liquid is not very high.
  • a second channel is formed between said flexible sheets in which the channel of the valve, this second channel having an external end adjacent to an edge of said enclosure and the other end in communication with the interior of this enclosure
  • This invention also relates to a method of packaging of a liquid in a sachet or an enclosure comprising said second channel, according to which the bag is formed as well as the two channels, we leave at least open the outer end of said second channel adjacent to the edge of said sachet, said liquid is introduced through this second channel and closing said outer end of the second channel.
  • This invention finally relates to a use of said sealed enclosure according to claim 15.
  • the proposed solution does not add any additional element to the sealed enclosure compared to known solutions, the tongue being formed by a portion of the enclosure wall. This solution therefore does not no increase in production costs.
  • existing production lines can continue to be used with very slight modifications for a advantage that is not negligible in terms of product.
  • the enclosure is protected against any attempt to violation. Hygiene conditions are perfectly guaranteed until the first use of the sachet.
  • the elements forming the bag and the valve are minimized, no added element is not necessary to ensure inviolability valve.
  • the sheet area required for realize the duct and the filling volume of the bag are optimized.
  • Figure 1 illustrates four strips 1, 2, 3, 4 of film monolayer or multilayer thermoplastic such as polystyrene, polypropylene, polyethylene or polyamide, endless, used for the manufacture of the waterproof bag, object of the invention.
  • Bands 1 and 4 wider, are intended to form the walls of the sachet, while the narrow strips 2 and 3 are used to make the valve.
  • the film thickness of strips 2 and 3 of the order of 40 ⁇ m is less than that of the film in bands 1 and 4 of around 100 ⁇ m, to make bands 2 and 3 more flexible to facilitate closing the valve.
  • the first operation is performed on sheet 1 and consists in pre-cutting tabs 5 at regular intervals.
  • Each tab 5 is intended to be located in the vicinity from one of the corners of the bag.
  • the end of this tongue 5 is cut while its parallel edges are pre-cut so that before use, the tongue 5 remains in the plane of sheet 1.
  • 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 tabs 5.
  • the third operation is to weld the sheets 2 and 3 along two parallel lines 7 and 8 (fig. 4) fitting out a channel 10 between them, the flexible walls of which are normally contiguous, but are likely to be discarded one from the other, thus constituting the valve controlling the distribution of the conditioned liquid.
  • These welds 7 and 8 get thinner where the heat-resistant varnish is 6.
  • two parallel cuts 9 are provided in the welds 7 and 8 and a cutout transverse 9a connects the parallel cutouts 9, putting thus channel 10 in communication with the outside.
  • a weld 12 which surrounds the long sides of the rectangle heat-resistant varnish 6 deposited on sheet 2 and which cut this rectangle 6 across its width, so as not to weld sheets 2 and 3 together at the location of the channel 10.
  • Welding 13 is also carried out, in the form of a rectangle, superimposed on the rectangle of heat-resistant varnish 6, so that only sheets 1 and 2 are welded together at the place of this rectangle 13.
  • we cover the strips 1, 2, 3 of the fourth strip 4 and three welds are made 14a, 14b, 14c, forming three sides of the sealed bag 15, one 14b along one of the edges of bands 1 and 4 and the two others 14a, 14c transversely to these bands.
  • the fourth side, adjacent to the other edge of strips 1 and 4 remains open to allow subsequent filling of the waterproof bag 15.
  • the last step is to separate the sachets sealed from each other between two welds 14a, 14c adjacent.
  • the waterproof bag 15 illustrated in FIG. 7 is ready to receive the liquid to be conditioned, after which the fourth side will be welded, enclosing the liquid so waterproof.
  • Figures 10 to 12 show how it is possible to access the contents of the sachet using a straw or any duct 17 allowing to make pass the liquid from the inside to the outside. It is enough detach the tab 5 and pull it towards the edge 14c of the bag 15. Since the tongue 5 is welded according to the welding rectangle 13 to the strip 2 constituting one of the walls of channel 10, by pulling it, we causes a tear in this wall 2, thus sparing a opening 16 of channel 10. This opening 16 allows the introduction of a tubular element 17 such as a straw or a pouring element. The length of this tubular element 17 must be sufficient to come out of the cut end 9a channel 10, thus bringing the contents of the sealed bag into communication with the outside.
  • the start of channel 10 has a sudden widening 10a intended to allow to accommodate and maintain one end folded 17a of straw 17 when you want to interrupt fluid consumption.
  • the background of 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 that forms this channel 10.
  • the edge of the tongue 5 adjoining the wall 1 of the bag watertight 15 is adjacent to the weld 14c, so that this welding limits the tear-off length of the tongue 5.
  • the variant illustrated in Figures 13 to 15 consists to be added to the part of the bag 15 fitted with the valve, a strip of a more rigid material, such as a strip of thicker material (on the order of 200-250 ⁇ m) 18, such as thermoplastic film of the same kind as that of the sheets 1 to 4.
  • This strip 18 is provided with parallel folding grooves 19 which are obtained by compression.
  • This strip 18 is attached to the bag by welding it to the tongue 5, itself welded according to rectangle 13 to sheet 2, as illustrated by Figures 5 to 7.
  • FIGS. 16 to 19 presents, in addition to channel 10 serving as a valve and distribution conduit liquid packaged in the bag, channel 20 intended only for filling the sachet.
  • the layer of savings varnish 6 also extends over a portion 6a of the width of the weld 14a forming the periphery of the bag, and over a certain length of this seal 14a, for the purpose which will be explained later.
  • channel 20 it is formed between the weld 8 and a weld 21 which extends along the inner edge sheets 2 and 3.
  • the following operation consists in introducing into the channel 10 a folded straw 17 and in the channel 20 a cannula filling 23. Once filling is complete, close the ends of channels 10 and 20 by welding the edge of the bag in the part of the width left free by the varnish savings 6a as illustrated in FIG. 19.
  • This bag can then be used as the described bag previously, by tearing off the tab 5 giving access at straw 17 and at distribution channel 10.
  • the invention could also be applied to other types of sealed enclosures for the packaging of liquid.
  • the invention is in no way limited to causes the membrane attached to the inside of the wall of the enclosure is constituted by a through strip the length or width of the enclosure, the use of a tape of this type is advantageous because it allows make the enclosure according to the invention continuously from strip materials.
  • the entire surface of strip 34 must not not necessarily be welded to the inside of the wall 1 of the sachet.
  • Figures 20 and 21 illustrate not only a variant of the process of FIGS. 1 to 7, but also a variant of the valve formed between the sheets 2 and 3 arranged between sheets 1 and 4 forming the sachet.
  • sheet 1 has not been shown, but it obviously exists.
  • FIG. 20 The first operation performed in Figure 20 is illustrated by section a-a in figure 21 and corresponds to welding 7 ', 8' delimiting the channel 10 'of the valve. As we can see, this channel is not with parallel edges and the purposes and functions of the variations will be explained below section thus given to channel 10.
  • a weld transverse 42 is formed near one end of the channel 10 ', the usefulness of this weld will be explained by the after.
  • 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 of which branches are not the same length.
  • this asymmetry of the branches of the U-shaped cut 9 ' coincides with the asymmetry of the narrowing in the middle from the 10 'channel.
  • This asymmetry of the 10 'channel and the cut 9 ' has shown that it improves the closure of the valve, that is to say of the part of the channel 10 'extending from the asymmetrical narrowing of this channel and the cut 9 ', 9'a.
  • a straw 17 ' is introduced into the channel 10'.
  • the diameter of this straw is such that it corresponds substantially the narrowing formed at the entrance to the channel 10 '. From this made a seal is obtained between the straw and the end inlet of the 10 'channel, so that the liquid which may have flow between channel 10 'and straw 17' during opening of the valve is prevented from leaving this channel 10 '.
  • the end of the straw 17 'introduced in the channel 10 ' has a bulge 17'a which serves to prevent straw 17 'from coming out of channel 10', this bulge coming up against the narrowing at the entrance from the 10 'channel.
  • the transverse weld 42 limits the displacement of the straw 17 'in the conduit 10'.
  • section d-d is carried out in parallel on the sheet 4 forming one of the walls of the bag. It consists of cutting the tongue 5.
  • the sheet 4 joins the two other sheets 2,3 and one non-weldable sheet (not shown is interposed between the straw and the adjacent sheet 3 sheet 4.
  • the welding 40 carried out at the e-e operation only welds sheets 3 and 4 together the opening 40a serves to leave free the end 5a of the tongue 5, the rest of this tongue being welded to the sheet 4.
  • the last operation consists in carrying out two points welds 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 7 ', 8' from channel 10 '.
  • These welds 43 connect the valve formed by the channel 10 'at the opposite edge of the sheets 2, 3 and 4. They thus delimit the width of the receiving accommodation the folded part of the straw 17 '.
  • the welding points 41 they are used to prevent leaves 2, 3 from following the straw 17 'when the bulge 17'a is brought into abutment against the narrowing located at the entrance of the channel 10 ', allowing the valve to close.
