Definitions

  • the present invention relates to a chain of bags, especially plastics, in particular bags for storage garbage, of the type called "sliding link", comprising a opening lined with a sheath in which is arranged a sliding link prehensile from the outside.
  • plastic bags In industrialized countries, waste and garbage, in particular household refuse, are stored in plastic bags. These plastic bags have generally two plastic faces connected to one another on their periphery by providing an opening area. These bags have the most often a rectangular shape, although other forms are possible: for example, the bottom of the bag may have a rounded shape. In the remainder of the description, for ease of reference, reference will be made to bags of rectangular shape, but it is understood that the bags according to the present invention are not limited to this form.
  • the bags can be prepared from two sheets rectangular plastics, by welding three sides of the rectangle and leaving the fourth side open. They can also be prepared from a single sheet of plastic material that is folded, either for form the bottom of the bag, either to form a lateral side of the bag, two of the other sides being heat sealed. In known manner, in the bags, the faces can be connected together by a bellows at the bottom and / or at a lateral side, preferably both lateral sides.
  • the link may consist of a single strand, both ends of the link being fixed between them. It can also consist of two strands, each strand being fixed by each of its ends to the sheath.
  • the link is, of preferably, a plastic tape capable of being heat sealed.
  • the sheath is usually prepared by folding the sheet of plastic material parallel to the opening and heat-sealing parallel to the edge of the film.
  • the sheath can be continuous or formed of two separate parts. This is particularly the case when the bags are formed by heat sealing the lateral sides and that the sheath is formed by folding the plastic sheet before heat sealing the sides side.
  • document DE 36 43 503 discloses a heat-sealable plastic sheet bag that has two welded strands by their ends to form a closing ring, movable in the sheath on both sides of the bag.
  • This bag has two recesses in the sheath at the lateral sides of the bag to allow gripping the closing ring and allow it to slide in the sheath to close the bag.
  • the recesses can also be placed at the middle of the opening, at an equal distance from the two lateral sides, especially when the link is made up of two strands attached at each end to the sheath by heat sealing at the same time as the side edges of the bag.
  • This bag has drawbacks: in bags of this type, to close the bag, the user pulls the link by grabbing it by each two recesses so as to slide the link and close the bag. It then makes a knot with the two link portions that have been drawn and slid to ensure that the bag does not run the risk of accidentally open during subsequent manipulations.
  • Document FR 1 397 298 discloses sachets for sliding closure of this type, enchained according to the preamble of claim 1, and their method of manufacture.
  • Each bag has a front face and a back face that present, each, on the side of the opening of a sachet, a hem enclosing a cordon in which one end of these cords is attached to even the side edge of the bag or in the vicinity of it inside the hem; the other end being detached or made detachable from the hem by a line of least resistance or discovered by a notch of the hem, to be grasped by the fingers.
  • This bag has drawbacks: indeed, the lines of perforations to make the end of the drawstring detachable are close to the border between two bags, so that they risk tear when the bags are separated at the end of the manufacturing process. These perforation lines must therefore meet specifications precise: too fragile, they are damaged at the end of the manufacturing process; too resistant to tearing, they instead make the cord unusable. These specifications complicate the manufacturing process and increase its cost.
  • the indentations or the lines of perforations are formed by a cutting tool like a knife to reciprocating motion at intervals corresponding to the width of a bag.
  • the process thus reaches a rate of production of bags relatively low compared to the operating rate of implemented machines, which corresponds to a scroll of the chain of manufacturing equal to the width of a bag, which increases the costs of operation, maintenance and replacement of said machines.
  • US Patent 2,798,523 also discloses tie bags. sliding and their methods of obtaining.
  • this patent discloses a chain of bags in which each bag has two recesses, as in DE 36 43 503 supra.
  • this patent discloses a single-recess bag obtained by a process which does not allow to get a chain of bags.
  • the present invention aims to provide link bags in which a single portion of the link is prehensible, bags not having the aforementioned drawbacks.
  • the subject of the invention is a chain of plurality of bags according to claim 1.
  • said transverse precut at the level each recess is performed substantially on an axis transverse symmetry of said recess, so that said recess be able to separate into two forms substantially symmetrical and specific to each respective bag after separating the bags from both sides of said precut.
  • the link disposed in each sheath of a bag consists of two strands interconnected at said recess.
  • the median bag among the three bags presents a first side side adjacent to the opposite side side of a second bag among said three bags, the two adjacent lateral sides of the median bag and the second bag terminating at said longitudinal edge in the bottom of a recess, said recess being straddling said bag median and said second bag; the second lateral side of the median bag being adjacent to the opposite lateral side of the third one of said three bags, the two adjacent lateral sides of the middle bag and the third bag do not communicating with any recess of said chain.
  • the chain is in the form of a winding around a substantially transverse direction, for facilitate its packaging, storage and transportation.
  • This method according to the invention is advantageous compared to method of the prior art according to FR 1 397 298, in which the material first of the process of manufacturing bags is a strip of material flexible or a flat sheath with a fold W and slit on one side.
  • the material first of the process of manufacturing bags is a strip of material flexible or a flat sheath with a fold W and slit on one side.
  • such a band must scroll with a well-controlled orientation; just as the W-fold of the sheath must be maintained constant shape and orientation.
  • the process according to the invention overcomes these costly constraints.
  • step c) substantially circular portions, so as to obtain in step h) above, bags each having a single recess in substantially quarter circle.
  • step d) substantially semicircular portions, so as to obtain in step h) above mentioned, bags each having a single recess in the form of substantially of a quarter circle.
  • Halving the frequency of cutouts portions of film compared to the prior art can accelerate the bag manufacturing and reduce manufacturing costs. Indeed, she leads to a reduction in the wear of the machines used for make these cuts and a reduction in their costs of operation, maintenance and replacement. Machines operate at two distinct frequencies, one for recesses both bags, the other to make the precuts to each bag; unlike the prior art where only one frequency identical is used.
  • the bag shown in FIG. 1 is designated in its together by the reference 1. It consists of two flat faces symmetrical with respect to a plane obtained by folding a sheet in two of plastic material relative to the bottom 3 of the bag.
  • the lateral sides 4 and 5 of the bag are obtained by heat sealing. Both sides are thus interconnected on their entire periphery with the exception of a so-called opening, opposite to the bottom 3.
  • the opening 6 of the bag is lined on each side by a sheath 7.
  • This sheath 7 is constituted by folding towards the inside of the sheet of plastic material on each side of the bag and by soldering 10 of this fold on the face, parallel to the edge of the opening 6.
  • the parts of this sheath 7 carried by the two faces of plastic are also welded between them at the lateral sides 4 and 5.
  • a sliding link consisting of two plastic strands generally of a different color from that of the constituent leaf of the sides of the bag.
  • a single recess 9 is provided at level of one of the lateral sides 5 of the bag, for the manual gripping of the sliding link 8.
  • each strand of link 8 is fixed by heat-sealing in the sheath 7 at the lateral side 4 of the bag, and the two strands are connected together by heat sealing at 11 at the level of the recess 9 formed in the sheath 7, in the extension of the other lateral side 5 of the bag 1.
  • the link formed by the two strands 8 heat sealed at 11 is accessible in the recess 9.
  • Link 8 is attached to the sheath at a point away from the recess 9. It is thus more easy to pull on the link 8, which causes the sheath to fold at level of the opening 6 of the bag.
  • a continuous sheath 14 of plastic film for example made of polyethylene, is scrolled on a machine (not shown) in the direction indicated by the arrow 15.
  • the sheath 14 is cut longitudinally. substantially along a symmetry plane P thereof, for example with a cutting knife (not shown), to obtain two separate half-sleeves 14a and 14b, visible in Figure 4.
  • a strand consisting of a plastic strip 8 is provided along each edge 12 longidutinal inside each half-sleeve (only one of which 14a is shown) to the right of the innermost semi-circular portion of each circular cutout 16 above.
  • the longitudinal edges 12 of the half-sheath are then folded inwards along a longitudinal axis B substantially diametrical with respect to the circular cutouts 16, to form a fold around each strand 8, so that each strand 8 remains accessible in a recess 18 of semicircular form.
  • each half-sleeve The two longitudinal edges 12 of each half-sleeve are first folded inwards over a distance d substantially greater than the radius of the aforementioned circular cuts, to form a fold along each edge 12, as can be seen in FIG. only 14 a is shown. Then semicircle portions 116 are cut at regular intervals corresponding to twice the width l of a bag. The portions 116 are cut in pairs at the same longitudinal level of the half-sleeve 14 with a diameter substantially coincident with the two edges 12. When the two edges 12 are superposed, of the ring gears (not shown) can cut the two double walls superimposed a half-sheath in one operation.
  • a strand consisting of a plastic strip 8 is inserted into each fold along each longitudinal edge 12 from the inside of each half-sleeve (only one of which 14a is shown) .
  • the recesses 18 of semicircular shape leave the strands 8 visible and accessible.
  • each half-sheath (only one of which 14a is shown), along the line 10, to form a sheath 7 on each of the edges 12. of the film.
  • the sheath 7 is formed by a double wall of the film whose recesses 18 of semicircular shape are superimposed.
  • the bottom 3 of the bags is the side of the half sleeve 14 opposed to the ducts 7.
  • each pair 19 and each pair 20 of heat seals adjacent is such that one can then separate the individual bags 1 by transverse cutting, between the heat seals of each pair.
  • the strands of the link 8 are attached in the sheath 7 by the pairs of heat seals 19, while the strands of the link 8 are connected together, level of semi-circular recesses 18, by pairs of heat seals 11 which are in the transverse extension of the pairs of heat-sealing 20. It is therefore understood that by the same operation welding, the sides 5 and the links 8 can be welded, independently of the each other.
  • Pre-cut consists of making a line of least resistance throughout the thickness of the bag, realizing example a line of perforations passing through both sides of the half-sheath.
  • the line of perforations between each pair of 19 heat seals also passes through the sheaths 7 of each face and the plastic strips 8 which are arranged therein.
  • the line of perforations between each pair of heat seals extends also at the heat-sealing pair 11 of the two ribbons 8 apparent in the recess 18.
  • a label 21 is glued on one side of each bag of the chain 13, that is to say at intervals of length equal to the width l of a bag on the chain 13.
  • the sleeve 14 having a constant scrolling speed, the heat seal pairs 19 and 20 are made by the same machine, operating at a double rate relative to the machine making the cuts of the portions in discs 16 or in half-disks 116.
  • FIG. 2 shows the chain 13 bags completed, formed bags 1a, 1b, 1c, 1d, the assembled by their side sides 4, 4a; 5a, 5b; 4b, 4c; 5c, 5d; 4th.
  • Each precut made between a pair of heat seals corresponds to a transverse axis of symmetry of the recess 18 at the bottom of which it ends.
  • each recess 18 in a semicircle straddles two adjacent bags and is adapted to share in recess 9 in the form of a quarter circle on each of the two bags. Therefore, the bags 1 a - e of the chain 13 are alternately with their recess 9 at the right end or the left end of their respective opening edges 6 a - e .
  • the finished chain 13 is detached from the production line when it comprises the desired number of bags and it can be rolled up for storage.
  • the chain 13 can also be used for the manufacture of individual bags 1 by separating the two edges on each side of the precuts.
  • the recesses could have a shape any, for example elliptical. So that the bags all have the same form of recess, it is preferable that the portions of film cut in the continuous sheath of film each have an axis transverse symmetry, and in the first embodiment of the process, a longitudinal axis of symmetry.
