Definitions

• the invention relates to a method of packaging: in a flexible bag of liquid or non - liquid product, food or other, aseptic or not.
• these soft bags also called “skins"
• these skins are at this time connected to each other through a pre-cut line, this so as to form a band. This facilitates the feeding of the unit intended to ensure their filling at the manufacturer of the product which they must contain.
• these soft pouches are equipped, each with a dispensing tap. In particular, before assembling the films by welding, it is punched in one of them, with regular space, an opening for the engagement and the welding of a bung in which is partially, the body of this tap of distribution.
• US Pat. No. 3,868,891 which describes a device for the continuous manufacture of flexible bags equipped with a bung, which are packaged in a box in a box, is thus known.
• the manufacturing process makes it possible to continuously produce a strip of flexible bags from two plastic films, or more in the case of multi-layer bags, joined edge to edge so as to constitute a single hose, welded and stamped at regular intervals. , in particular to incorporate a plug provided to receive a shutter.
• a first operation is to take the valve of the plug through which is then injected the product in the further.
• the valve is reengaged in the bung for a complete bonding.
• Document FR 2 814 968 discloses the design of a strip in which each flexible bag is filled, not by the orifice intended to receive the tap, but by another orifice solely dedicated to filling. This design requires the addition of a sealing operation after filling. In addition, it complicates the handling of the off because of the need to clear access to the second port for its filling and sealing.
• this dispensing valve although designed to avoid the presence of sharp edges, has none the less raised areas which, during handling without great care or during transport, can injure such a flexible pouch .
• this in case of detection of a defective item on a filling line, this generates a total stoppage of the installation and an obvious loss of production.
• Such strips comprising a single row of outres, are therefore not stable, are difficult to store in the state in a package directly at the output of the production line. Moreover, their inconvenient use downstream often disrupts production.
• the filling operation can pollute the area of the second transverse weld, by splash or other, making this weld, again, less reliable.
• the bottles are made by unwinding in parallel of two multilayer complex films, in one of these films being punched, at regular intervals, a hole for the reception and welding of a bung on which is preassembled a tap.
• the two films 1 ' are welded to one another so as to form the bottles that are separated from each other through successive transverse cuts in a suitable cutting unit.
• the pre-assembly of the tap on the bung, disassembly and reassembly are operations at risk of introduction of material chips into the flexible bag, besides that to remove the valve it must be perfectly maintained, without this maintenance does not present a risk of alteration of the pouch itself.
• This solution still poses the problem of the decontamination of the bottles before filling. In the end, we realize that it is hardly suitable for aseptic product packaging. This solution again raises the problem of responsibility for the manufacture of these flexible bags.
• the opening in the lower part of the funnel must be defined in a smaller section than that of the packaging box to be certain of the engagement of the dry bag without a hitch through the opening preserved in the level of this carton.
• the weight is not sufficient to force their passage through the latter whose outlet opening is section lessened.
• the friction of the off against the walls of the funnel can also result in wear that can cause leakage or breakage of the further.
• it is often performed in a stopping position, which can result in a reduction of the rate of the line.
• the present invention aims, in the end, to meet the disadvantages of the state of the art mentioned above.
• this invention relates, in particular, to a flexible bag packaging method of liquid or non-liquid product, food or other, aseptic or not, characterized in that:
• the method according to the invention provides that:
• a strip of flexible bags is engaged in a cutting unit to individualize these flexible bags;
• each of these flexible bags is positioned through its bung under a filling station
• a shutter is mounted permanently on said bung
• a packaging carton is preformed around a tubular forming mandrel extending an introduction funnel; this forming mandrel also serves as a distribution funnel;
• a flexible bag filled in the preformed packaging carton is poured through said funnel and the forming mandrel;
• a strip comprising two or more rows of juxtaposed pockets is packaged by superimposition of at least two films of suitable synthetic material and packaged this band with rows of multiple flexible bags in a waterproof case transport.
• this multi-row band is engaged in a longitudinal and transverse cutting unit to individualize the flexible bags. Thanks to a suitable fairing, this cutting unit ensures the protection of soft bags against any foreign body.
• the advantages which flow from the present invention consist, first of all, in that by avoiding to premount the shutter, such as a dispensing tap, on the filling bung, it avoids the introduction into the flexible pouch of debris resulting from successive removal and assembly of this shutter in said bung.
• the plug and the body of the shutter in particular the tap, were to be designed to allow a premounting in view of a subsequent withdrawal of the shutter, these features are no longer required in the solution according to the invention.
• the height of the bung and the length of the body of the tap may be smaller to allow only a final assembly of one in the other. This results in an obvious gain in material. This also significantly reduces the amount of entrapped oxygen, thus contributing to a better preservation of the packaged products sensitive to oxidation. Moreover, it results in less space for packaging.
• the packaging of such a strip, directly at the output of the production line, in a large-sized sealed transport case is rendered easier, including allowing zig-zag storage, alternating pleats, in the carton, which allows still to have staggered the smallest protuberances that still define the filling bungs.
• this band whose width can be adapted to that of this fund is unlikely to intermingle during transport. It should also be noted that the packaging of a multi - row band, without dispensing tap, is likely to be automated much more easily than the packaging of a band having only one row of outrages, moreover , pre-equipped with dispensing faucet.
• Another advantage of the invention consists in the reduction of waste during the manufacture of the webs. Indeed, the fact of making several rows makes it possible to reduce the overflows of width, compared to traditional production machines producing only in mono.
• the individualization of the flexible bags, starting from a multi - row band, on the filling site is an operation which is not only very easily managed, but avoids the layout of pre - cut lines like this. has been required in the past.

• the present invention relates to a method of packaging in flexible bags of liquid or non-liquid product, food or other, aseptic or not.
• this method consists of designing a strip 1 of at least two rows IA, IB, IC, ID of flexible bags 2 by superposing and welding at least two films 3, 4 of suitable material. .
• the structure of the upper film 3 and the structure of the lower film 4 that has just been superimposed for welding can be constituted, in reality, in the form of a multilayer complex starting from several films 3A. , 3B, 4A, 4B unfolding simultaneously from reel rollers 5 located upstream of the production line 7 of this band 1 of flexible bags 2.

• the width of the weld lines longitudinal and transverse is determined to ensure the sealing of the various flexible bags once individualized, just as between two rows successive or two flexible pouches that follow each other can be made a double weld line spaced.
• the band 1 of flexible bags 2 having only one plug 6, is packaged in a sealed transport case 8 adapted, as can be seen in Figure 2.
• the width 9 of this band 1 can be substantially adjusted to that 10 of this box 8, which allows the ordered folding of said strip 1 in the latter, without risk. entanglement during transport.

• the flexible bags 2 may undergo a sealing control operation, in particular by prior compression, and then weighed, so that in case of leakage the risk of contamination is as low as possible.
• This leakage control can be carried out in a different way, in particular by putting the flexible bag in a vacuum chamber.
• a preliminary vacuum can be provided by the latter or an auxiliary head, this to suck air contained in a flexible bag 2 before injecting the product to be conditioned.
