Definitions
- the present invention relates to a bag, in particular of plastic, in particular a bag for storing household waste, of the type known as "with a sliding link", comprising an opening bordered by a sheath in which is disposed a gripping sliding link of the exterior and a method of manufacturing such a bag.
- waste and garbage in particular household garbage, is stored in plastic bags.
- plastic bags generally have two plastic faces connected to each other on their periphery, leaving an opening area.
- These bags most often have a rectangular shape, although other shapes are possible: for example, the bottom of the bag can have a rounded shape.
- the bags can be prepared from two rectangular sheets of plastic, 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 which is folded, either to form the bottom of the bag, or 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 on the two lateral sides. It is also known to manufacture so-called sliding link bags in which the opening of the bag, whatever it is, is bordered by a sheath in which a link is capable of sliding. The link can consist of a single strand, the two ends of the link being fixed between them.
- the link can also consist of two strands, each strand being fixed by each of its ends to the sheath.
- the link is preferably a plastic tape capable of being heat-welded.
- the sheath is generally prepared by folding the plastic sheet parallel to the opening and by heat sealing it. parallel to the edge of the film.
- the sheath can be continuous or formed from two separate parts. This is in particular the case when the bags are formed by thermo-welding of the lateral sides and that the sheath is formed by folding up the plastic sheet before thermo-welding of the lateral sides.
- Such bags with a sliding link in plastic material, which is substantially non-elastic, are described in patents EP-953 511 and EP-1 232 954 belonging to the applicant esse.
- this sliding link makes it possible to elastically retain the bag on the trash can, in a wide range of trash sizes, while limiting the risk that the bag slides inside the trash, for example under the effect of the weight of the waste inside the bag.
- the aforementioned elastic sliding link bags have a double drawback, due to the presence of relatively deep lateral elements which are formed on the longitudinal edge of the opening of the bag.
- the presence of these relatively large elements has the disadvantage of not allowing the complete closure of the bag, when the sliding links are knotted, after filling the bag. Indeed, during the transport or storage of bags filled with waste, waste could escape through these removal.
- the presence of these relatively large elements reduces the length of sheath in contact with the link, and therefore weakens the bag when it is transported full by using the elastic sliding link as a handle.
- DE-202 07 942-U1 provides for arrangements placed in the vicinity and at a distance from the side edges of the bag, so that the elastic sliding links remain linked at their lateral ends to the side edges of the bag, the welds of the elastic links delimiting the length at rest of the elastic links being accessible at said level.
- the ends of the sliding links are no longer free, but connected to the side edges of the bag.
- all these bags with elastic sliding link have the common drawback that the elastic link may not have sufficient tensile strength to support a large weight of waste in the bag, during transport.
- the object of the invention is therefore to propose a bag of the type with elastic sliding link making it possible to elastically fix the periphery of the bag on a receptacle, which makes it possible to avoid the risks of falling of waste out of the bag, after closing it using the sliding links.
- the invention also aims to limit the risk of rupture or tearing of the sliding link or the risk of deformation of the sliding link during transport of the bag filled in particular with waste.
- the invention relates to a bag consisting of two faces connected together over their entire periphery, with the exception of a longitudinal edge, the bag having an opening opening onto said longitudinal edge, the two sides of the bag being welded to each other along the two opposite lateral edges, each face comprising a sheath bordering said opening and in which a sliding link made of elastic material is disposed, each elastic link being grippable from the outside by at least one lateral recess provided through said sheaths, in the vicinity of a side border of the bag, the ends of the elastic links being connected to each other at each lateral recess by a so-called intermediate welding zone so that the elastic links form a closed loop whose length of the periphery is less than that of the longitudinal edge of the bag, characterized in that each sheath has a second sliding link made of substantially non-elastic material, the ends of which are linked to the lateral edges of the bag.
- the elastic sliding link essentially serves to elastically hold the bag on a receptacle, while the non-elastic link essentially serves to close the bag and to carry it; it is then possible to reduce the width of the elastic link, which must no longer support heavy loads during transport.
- the elastic link and the non-elastic link are substantially offset in the height direction of the bag and housed in the same sheath.
- the elastic link and the non-elastic link housed in a sheath are temporarily and detachably connected by a partial overlap zone so as to allow the elastic link to be detached during use of the bag, for example at the latest during the tensioning of the elastic link, each lateral recess extending to the neighboring lateral border so as to leave apparent said overlapping zone.
- the overlap zone is not linked to the sheath, at the level of the lateral border.
- the connection between the two links at the level of the overlap zone is of the bonding type with low adhesive power, for example detachable during the tensioning of the elastic link.
- it may be an adhesive used for repositionable adhesive tapes.
- the connection between the two links at the overlap area is of the bonding type with high adhesive power, detachable by the addition of a heat energy source, before use of the bag.
- the elastic links comprise, in the immediate vicinity of the overlapping zone, a tearable pre-cut line. This precut line constitutes a line of weakness capable of tearing during a simple tensioning of the elastic link.
- the overlap zone is temporary in nature and is not intended to constitute a permanent connection zone between the elastic link and the walls of the bag, the elastic link not being integral with the walls of the bag, at the level of a recess, during its use.
- the sheath is formed by a fold of the corresponding face along the longitudinal edge of the bag, each fold being welded according to a first longitudinal weld on the corresponding face to constitute a first sheath in which the elastic link is housed, said fold extending beyond said first longitudinal weld by a skirt which is welded according to a second longitudinal weld on the same face of the bag, to constitute a second sheath in which is housed the link not -elastic, the elastic and non-elastic links being separated by the first aforementioned longitudinal weld.
- each lateral recess extends from a lateral border of the bag through the first sheath only.
- the bag includes a recess in its median part at the level of each second sheath, to allow gripping of the non-elastic ties.
- the elastic link and the non-elastic link are superimposed along the longitudinal edge of the bag, so that the elastic links form a closed loop circumscribed by the non-elastic links, each lateral recess being spaced from the adjacent lateral border of the bag by a sheath section in which only the non-elastic link is disposed, the ends of the elastic links at the lateral recess not being linked to the neighboring lateral border from the bag.
- the bag includes a recess in the middle part of each sheath, to facilitate gripping of the non-elastic ties.
- the longitudinal weld is continuous, or not continuous.
- the present invention also relates to a process for the continuous production of a chain of bags, said process comprising the steps consisting in: a) cutting portions of film in the vicinity of the two longitudinal edges of a folded sheet, at corresponding regular intervals at least the width of a bag, for example one or two bag widths, said cut portions being substantially matched to form lateral elements of the bags b) to have inside said folded sheet two strands each consisting of a ribbon of non-elastic material and a ribbon of elastic material pre-glued with a temporary partial overlap zone on the non-elastic ribbon, along said longitudinal edge, the two strands being arranged in line with said cut portions on each face of the sheet c) step b) being carried out after or before having folded inwards each longitudinal edge of the sheet to
- This manufacturing process has the advantage of allowing the continuous production of a chain of bags with a double sliding link, one of which is elastic, using a single strand connecting an elastic ribbon and a non-elastic ribbon.
- it is more difficult to continuously manufacture a chain of bags with an elastic sliding link, since the tensioning of this elastic link risks causing defects in the heat seals.
- the fact that the elastic ribbon is temporarily carried by the non-elastic ribbon during the manufacture of the bag makes it possible to tension the complete strand, by exerting a tensile force essentially on the non-elastic ribbon of the composite strand.
- the temporary overlap zone can be removed, for example by adding heat if it is a detachable glue under heat, or else '' use by the user, by exerting a simple tensioning of the elastic link, if it is a weakly adhesive glue, or by tearing the connection between the elastic link and the non-elastic link if a line pre-cutting is provided for this purpose.
- the method consists in arranging in the aforementioned step b) a strand, the elastic tape of which is provided with a longitudinal precut line in the immediate vicinity of the zone of partial overlap.

- - Figure 7 is a partial schematic view from above according to arrow VII of Figure 6; and
- - Figure 8 is a partially cutaway and perspective view
- the bag 1 according to the invention consists of two substantially parallel faces la, lb rectangular, the faces la, lb being formed by the same sheet of plastic material which is folded to form the bottom of the bag, this bottom being rounded when the bag is in the carrying position, as shown in FIG. 2.
- the faces 1a and 1b are brought back one against each other and are connected at the bottom 1 c by a flat fold, as shown in FIG. 1.
- the faces 1a and 1b are connected together by corresponding welds 2a and 3a.
- welds 2a and 3a extend substantially over the entire height of the bag 1 and form a vertical line, but these welds may not be linear but extend over the entire lateral marginal zone of the bag.
- the periphery of the bag On the side opposite the bottom 1c, the periphery of the bag has an opening area ld defined along the longitudinal edge of each face 1a and 1b, the longitudinal edge of each face 1a and 1b extending at the level of the area of opening ld, by an internal fold 4, one end of which is welded to the corresponding face of the bag by a longitudinal weld 4a.
- This fold 4 is extended beyond the longitudinal weld 4a by a skirt 4b, which can be free or else itself welded to the corresponding face of the bag.
- a skirt 4b which can be free or else itself welded to the corresponding face of the bag.
- the internal fold 4 is welded to the internal wall of each side of the bag by two weld lines, the longitudinal lower weld line 4a and an intermediate weld line longitudinal 7. Between the longitudinal edge of the bag opening and the first weld line 7, the fold 4 forms a first sheath 8 in which is disposed an elastic sliding link 16. Between the two weld lines 4a and 7, the fold forms a second sheath 5 in which is disposed a sliding link made of non-elastic plastic material 6. The two sheaths 5 and 8 together form the sheath 4.
- the intermediate weld line 7 is not essential and could be eliminated, without modifying the functioning of the bag 1.
- the longitudinal welds inals 4a and 7 are preferably continuous over the entire width of the bag. They can also be non-continuous, broken lines or dotted lines.
- Figures 1 and 2 there is shown a recess 12, substantially in the middle part of each sheath 5 of the sheath 4, the removal 12 passing through the faces 1a and 1b of the bag, on each side of the latter. As can be seen in FIG.
- this median recess 12 does not cross the internal wall of the fold 4 but one could, as a variant, provide such a recess 12 completely through.
- This recess is shown here in a substantially circular shape, but it could have any shape, for example oval or square, or semi-circular, and it is not necessary that the sliding link 6 is visible over its entire height through the 'embervement 12.
- This recess 12 can be astride the two sleeves 5 and 8, in a manner substantially similar to the recess 1 12 which will be described later with reference to the embodiment of Figures 3 and 4. This recess 12 can even completely cover the sheath 5.
- Such a median recess 12 is also not essential, and it would suffice that the lateral members 17 (described below) extend partially through the sleeves 5 to give access from the outside to the sliding link 6.
- the main function of the elastic link 16 is to allow the periphery of the bag to be resiliently adjusted on the edge of a receptacle , while the non-elastic link 6 will be used mainly to carry the bag when filled with waste and / or to tie the links 6 in order to close the bag. Given the arrangement of the two links 6 and 16, it is understood that when closing the bag will be completely closed, avoiding or limiting the risk of falling waste out of the bag during transport or storage. When transporting the full bag, the other plastic link 6 is used to prevent the elastic link from being deformed.
- FIG. 2 we indicated by the reference numeral I the interior of the bag, in the open position.
- the bag 1 comprises two lateral extensions 17 whose longitudinal extension makes it possible to produce an intermediate heat seal 19 between the two strands of the sliding link 16, at a distance from their end welds 18 which are in the vertical extension of the lateral welds 2a and 3a from the bag.
- the spacing L2 between the two welds 19 on the sliding link 16 is substantially less than the length L1 between the welds of the two lateral edges 2 and 3 of the bag, which makes it possible to produce an elastic sliding link in a closed loop having a periphery of length less than that of the opening of the bag.
- the free ends of the sliding link 16 are always welded at 18 in the extension of the weld lines 2a and 3a, but these welds 18 have no effect, because it is the welds 19 which define the closed loop of the sliding link 16.
- the ends of the sliding link 16 beyond the transverse welds 19 could be cut, as shown for example in the German utility model DE-201 10 350-U 1.
- the bag 1 could have a single lateral recess for gripping the elastic link 16, without departing from the scope of the present invention.
- Each lateral recess can have any shape, in particular a quarter of a circle, a quarter of an ellipse or a rectangular.
- the two links 6 and 16 are of a different color from the color of the sheet constituting the faces 1a and 1b and the two links can themselves be distinguished by different colors.
- the link 16 is made of elastic material, for example ethylene vinyl acetate (EVA) or else of thermoplastic rubber, or of elastomeric polyolefin, or else a mixture of elastomeric rubber and low density polyethylene , as indicated for example in patent US-5, 133,607.
- the other non-elastic link 6 is, for example, made of plastic material, for example high density polyethylene.
- the same reference numbers will designate identical or analogous elements.
- the fold 4 forms a sheath with a single housing or sheath 5, in which are arranged the two non-elastic 6 and elastic 16 links which are connected together by a zone marginal overlap 120, the two links 6 and 16 being offset in the height direction of the bag 101, the elastic link 16 is preferably provided in the immediate vicinity of the longitudinal edge of the opening ld of the bag.
- the elastic link 16 has a substantially reduced height compared to that of the non-elastic link 6, because the elastic link 16 is generally not used for carrying the bag once it is filled.
- the bag 101 of FIG. 3 is essentially distinguished from the bag 1 of FIG.
- each lateral recess 17 extends in the region of the lateral borders 2 and 3 up to the weld zone of said lateral borders with the link. non-elastic 6, so as to reveal the overlapping area 120.
- each transverse weld line 2a and 3a on the side edges of the bag cannot come to weld the elastic band 16 simultaneously with said side edges.
- an additional median recess 112 has been shown, centered substantially on the partial overlap zone 120 and thus giving access to both the non-elastic link 6 and the elastic link 16.
- a median recess 1 12 is not necessary, because the user can already access the non-elastic link 6 by the lateral members 17.
- the partial or marginal temporary overlap zone is obtained by a layer of glue with low adhesive power between the two strands 6 and 16, which allows detachment and detachment of the strand 16 and therefore its free sliding in the sheath 4, when the user grasps the link 16 to put it under tension around the periphery of a bin, for example.
- the layer of adhesive at the level of the partial overlap zone 120 could be made to have a strong adhesive power, but for this layer of adhesive to be degraded or sublimated, by calorific contribution, in particular by contribution of heat, at the end of the process of manufacturing a chain of bags, so that the elastic link 16 is already detached from the non-elastic link 6, before use by the user.
- the elastic band 16 can comprise a precut line or a weakening line 121, in the immediate vicinity of the overlapping zone 120, in order to allow the separation of the elastic band 16 and its free sliding in the sheath 4, during tensioning of the elastic link 16 by the user.
- FIG. 8 represents a step in a process for the continuous production of a chain of bags from which the aforementioned bag 101 may originate.
- a continuous sheath of plastic film for example polyethylene
- a machine not shown, which is cut longitudinally in its center to obtain two separate half sheaths.
- circular or elliptical portions are cut at regular intervals corresponding to once the width of a bag (or twice the width of a bag if only one lateral recess is provided per bag) , in order to form semi-circular or semi-elliptical elements after folding the longitudinal edge of the sheet of the half sheath inwards, as shown in FIG. 8.
- the shape of the cut can be any, for example square, rectangular or other.
- a strand is introduced inside each fold, before closing it with a longitudinal heat seal to form the sheath 4.
- This strand here consists of a strip of elastic material 16 pre-glued on a zone of marginal overlap on another plastic tape 6, over its entire length, the elastic tape possibly being pre-cut, as indicated with reference to FIG. 5 above.
- this strand could completely reverse the operations, by first placing this strand in line with each circular or elliptical cut and then folding the longitudinal edge of the sheet to form the fold. The rest of the process is the same in both cases; the internal edge of the fold is heat-sealed (along a line 4a) on each side of the sheet to form the sheaths 4, in the direction of travel F indicated in FIG. 8.
- pairs of thermo-welds 2a and 3a are made at each semi-circular or semi-elliptical cut, in order to divide them into two lateral portions 17 in a quarter circle or in a quarter ellipse each corresponding to a adjacent chain bag.
- Each pair of heat seals 2a or 3a is such that the individual bags 101 can then be separated by transverse cutting or by pre-cutting between the heat seals of each pair.
- the machine also performs transverse thermal welds limited to the portion corresponding to the elastic tape 16 of the strand to form the aforementioned thermal welds 19 limiting the length of the periphery at rest of the elastic link.
- Such a method has the advantage of being able to carry out heat seals on the chain of bags, without the risk of degrading these heat seals due to an uncontrolled tensioning of the elastic link, the latter being supported by the ribbon not -elastic which undergoes most of the tensioning as it travels through the machine.
- the order of the steps for producing the heat seals 4a, 2a and 3a, and 19 can be modified, without departing from the scope of the invention.
- a bag 201 which is distinguished in particular from the previous bags by the fact that a single lateral recess 217 is provided, although the other bags 1 and 101 can also have a single lateral recess, and that the bag 201 can also have two.
- This bag 201 is further distinguished by the fact that the two elastic 16 and non-elastic 6 links are superimposed along the longitudinal edge ld of the opening of the bag, and are not offset in the transverse direction, so that the elastic link 16 forms a closed loop circumscribed by the non-elastic link 6, as best seen in FIG. 7.
- each sliding link 16 is accessible from the outside, by means of the lateral elevation 217 made in the walls of each sheath 4, along the free edge of the opening zone ld of the bag.
- each recess 217 is obtained by cutting, in a semicircle shape, the two walls of each fold 4.
- the recesses 217 can have any shape, for example rectangular or other.
- the lateral elevation 217 is formed through the sheaths 4, in the vicinity of the lateral edge 2 of the bag, but at a distance therefrom, so as to provide a section of sheath 220 between the lateral edge 2 and the lateral erection 217.
- the two links 6 and 16 are welded at one end with the side edge 3 of the bag along the transverse weld 3 a.
- the opposite ends of the two strands of the elastic link 16 are welded together along a transverse weld 19 called intermediate at the level of the lateral members 217.
- the distance between the transverse weld 19 and the weld 3a on the lateral border opposite is substantially less than the length L1 between the welds 2a and 3a of the two lateral edges 2 and 3 of the bag, so that the sliding link 16 defines a closed loop whose periphery is of length less than that of the longitudinal edge of the bag .
- the two strands of the non-elastic link 6 extend beyond the lateral members 217 and are partially housed in the sheath section 220 on each side of the bag, in order to be fixed to the lateral border 2.
- a another median recess 212 for example semi-circular, allowing access in particular to the non-elastic sliding link 6, to facilitate the gripping of the two strands, for the purpose of transporting and / or knotting the links.
- the link 6 is fixed to the sheath on the two lateral edges of the bag, it is easier to pull the link 6 from the member 212, to cause the closure of the bag 1, by causing the sheath to pucker at the opening ld of the bag.
- the member 212 extends only over part of the height of the sliding link 6, unlike the member 217 which extends substantially over the entire height of the sliding link 16.
