Definitions
- the present invention relates to a bag, in particular plastic, in particular a refuse storage bag, of the type called "elastic band", bordering 1 * opening of the bag to help retain resiliently the bag on a bin, and a method of manufacturing such a bag.
- plastic in particular a refuse storage bag
- the type called "elastic band” bordering 1 * opening of the bag to help retain resiliently the bag on a bin
- a method of manufacturing such a bag In general, in industrialized countries, waste and garbage, in particular household garbage, is stored in plastic bags. These 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.
- the link can consist of a single strand, the two 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 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 elastic link in closed loop is characterized in that the length of its periphery is less than that of the opening of the bag, so that the user must elastically extend the sliding link to come and fix it around the periphery of a receptacle, for example a trash can.
- 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 cutouts which are formed on the longitudinal edge of the opening of the bag.
- This elastic tape is grippable from the outside by the user, after the edge of the bag has been folded around the neck of a bin, and the user can elastically extend it so that the tape forms a loop closed that can enclose the periphery of the container, allowing the bag to be held resiliently on the trash can.
- the elastic ribbon preferably rubber, can be chosen so as to have a maximum elongation of 800%, this elastic ribbon preferably has an elastic elongation of less than 500%.
- the elastic tape has a length at rest of the order of a quarter of the length of the periphery of the container.
- the elastic ribbon is elongated so as to surround only three sides of the container, which corresponds to an elastic elongation of the order of 200%, that is to say a tripling of its length.
- the elastic ribbon is elongated so as to form a closed loop which encloses the entire periphery of the container, which corresponds to an elastic elongation of the order of 400%, that is to say a multiplication by five of its length at rest.
- the elastic ribbon has a length slightly less than the half-periphery of the container, so that it is necessary to form a closed loop with the elastic ribbon to ensure the elastic retention of the bag on the container, which corresponds to an elastic elongation at least equal to 200%, that is to say at least a tripling of its length.
- this elastic tape is used only for the elastic retention of the bag. on the container, while the plastic sliding link is used for knotting, in order to close the bag.
- document EP-A-1 266 837 describes a bag of the sliding link type made of plastic material, further comprising an elastic band which is fixed at its ends to the side edges of the bag and is, in a variant, housed in the same sheath as the plastic sliding link, or else disposed on the outer face of said sheath.
- the elastic extension of the tape must be greater than 200%, for example 250% and preferably 300% or more.
- the invention therefore aims to provide a bag of the elastic band type for resiliently fixing the periphery of the bag on a receptacle and which avoids the aforementioned drawbacks. Another object of the invention is to avoid the risk of the waste falling out of the bag, after it has been closed. The invention also aims to limit the risk of rupture or tearing of the elastic band or the risks of deformation of the elastic band 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 two opposite lateral edges, at least one face being provided, in the vicinity of said opening, with at least one elastic band connected to said face by two connecting zones so that the useful length at rest of said elastic band between the two connection zones corresponds to the spacing between the two connection zones on the bag and is less than the length of the longitudinal edge of said face of the bag, a bag of this type being described in document EP-A-1 013 567.
- the bag according to the invention is characterized in that the elastic band extends over the entire width of the bag, from one side border to the other, said elastic band being welded to both faces of the bag along said lateral edges, at least one of the two aforementioned connecting zones forming a so-called intermediate connecting zone located at a distance from the two aforementioned lateral edges.
- the useful length at rest of the elastic band can vary slightly, depending on the elasticity of the band and its slight deformation when it is welded to the bag.
- This elastic band which is not housed in a sheath, can thus be manufactured continuously in a process for manufacturing a chain of bags, while having a reduced useful length, corresponding to the narrowing of the extensible and grippable part of the outside of said elastic band due to the presence of the intermediate connection zone between the two lateral edges of the bag.
- the elastic band has a length at rest markedly less than the width of the bag. Even if a passage, on a purely general basis and without any example of application, indicates that this strip can extend over the entire width of the bag, it is by no means provided that it can be welded to the side edges of the bag.
- thermo-adhesive glue which cannot therefore be located at the welds of the side edges of the bag, without affecting the good bonding of the strip to the bag.
- Each strip is bonded, individually and discontinuously, as visible in FIGS. 7 and 17, which distances the person skilled in the art from the present invention which is suitable for welding a continuous elastic strip over the length of a chain of bags.
- each side of the bag has a sheath bordering said opening and in which a non-elastic sliding link is disposed, each non-elastic sliding link being graspable from the outside by at least one recess provided through said sheaths, so that this non-elastic sliding link is essentially used for knotting to close the bag, while the elastic band is mainly used for elastic maintenance of the bag on a container.
- the intermediate connection zone can be produced at least partially on a double thickness of plastic sheets formed by one face of the bag and the aforementioned skirt.
- this intermediate connection zone does not extend in the part of the fold forming the sheath, in order to allow the non-elastic link to slide freely in the sheath.
- the fact of welding the elastic band at its intermediate connection zone on a double thickness of sheets makes it possible to reinforce this intermediate weld which is subjected to high tensile stresses.
- each side of the bag associated with the elastic band is folded inwards along the longitudinal edge of the bag, so that the elastic band is connected to said face, at least partially overlapping said fold.
- the other of the two aforementioned connection zones forms another intermediate connection zone located at a distance from the two aforementioned lateral edges and from the first intermediate connection zone.
- the other of the two aforementioned connecting zones is formed by the zone for welding the elastic band with the side edge of the bag which is the most distant from the aforementioned intermediate connecting zone.
- the two sides of the bag form a double thickness of sheets for the connection of the elastic band at the side edge.
- each elastic band is connected to an internal face of the bag.
- each elastic band can be connected to an external face of the bag.
- each elastic band is cut longitudinally into two vertically adjacent strands, the respective connecting zones of which are in the vertical extension of each other, so that the two strands form with the bag a closed loop, each strand of which is intended to enclose an opposite side of a container.
- one of the strands will remain along the face of the bag which carries it, while the other strand will be elastically elongated so as to grip the opposite side of the container.
- the intermediate connection zone of the elastically elongated strand which is subjected to the highest stresses, is thus locally reinforced by the intermediate connection zone of the adjacent strand.
- the elastic band has a degree of elongation less than 150%, and preferably of the order of 100%.
- this elastic band is based on ethylene vinyl acetate (EVA).
- EVA ethylene vinyl acetate
- 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) placing, inside a folded sheet, at least one elastic ribbon, along one longitudinal edges of the sheet; b) performing, at regular intervals corresponding to the width of a bag, at least one transverse heat seal limited to the height of the elastic tape only, to form an intermediate connection zone of the elastic tape on the corresponding internal face of the leaf ; c) to carry out, at regular intervals, corresponding to the width of a bag, a plurality of pairs of adjacent transverse heat seals corresponding to the side edges of the bags, so as to heat seal with the side edges of the bags the elastic tape mentioned above, said pairs of transverse thermowelds being carried out at a distance from the aforementioned
- This manufacturing method has the advantage of allowing the continuous production of a chain of bags with an elastic band, the useful length of which at rest is less than the width of one side of the bag, without risking gathering the body of the bag.
- the method comprises the additional step consisting: e) before step a) or b), of folding inwards each longitudinal edge of the sheet to form an internal fold, the aforementioned elastic ribbon being placed on a fold , with an at least partial overlap, so that the elastic tape is welded in step b) to at least a double thickness of material at its intermediate connection zone.
- the method comprises the additional steps consisting before step a): f) of cutting portions of film in the vicinity of the two longitudinal edges of the folded sheet, at regular intervals corresponding at least to the width of a bag, for example one or two bag widths; g) placing inside said folded sheet two ribbons of non-elastic material, in line with said cut portions on each side of the sheet so that each non-elastic strip is housed inside a fold; h) thermally welding the folds parallel to the longitudinal direction, to form a sheath in which is housed each non-elastic tape, the elastic tape at least partially overlapping the remaining portion forming the skirt of the fold.

- - Figure 6 is an elevational view of a third embodiment of the bag according to the invention, comprising an external elastic band;
- - Figure 7 is an elevational view of a third embodiment of the bag according to the invention, comprising an external elastic band;
- 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 the other and are connected at the bottom with a flat fold, as shown in Figure 1.
- the faces la and lb 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.
- the longitudinal weld 4a is preferably continuous over the entire width of the bag. It can also be non-continuous, broken line or dotted line.
- the internal fold 4 forms a sheath 8 in which is disposed a non-elastic sliding link 6.
- a strip of elastic material 16 is arranged, which is connected to the lateral edges 2 and 3 by the transverse weld lines 2a and 3a. As best seen in FIG.
- the elastic band 16 completely overlaps the skirt 4b, without however interfering with the sheath 8, so that the non-elastic sliding link, for example made of plastic, can freely slide between its ends which are also welded with transverse welds 2a and 3a.
- the lower edge of the elastic band 16 may exceed or correspond exactly to the lower edge of the skirt 4b.
- the elastic band 16 has a so-called intermediate connection zone 17 with the face 1a of the bag, which is constituted by a vertical line of welding or bonding or the like, this line 17 being limited to the height of the band 16.
- each face of the bag could include an elastic band.
- Figures 1 and 2 there is shown a recess 12, substantially in the middle part of each sheath 8, along the longitudinal edge of the opening of the bag, the recess 12 passing through the faces 1a and 1b of the bag, each side of it.
- This recess is shown here in a substantially semi-circular shape, but it could have any shape, for example oval or square, or other, and it is not necessary that the sliding link 6 is visible over its entire height through the 'recess 12.
- This recess 12 may be provided laterally, in a manner substantially similar to the recess 112 which will be described later with reference to the embodiments of Figures 6 and 7.
- the main function of the elastic band 16 is to allow '' Elastically adjust the periphery of the bag to 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 for closing of the bag (see Figure 8).
- the limited weld line 17 is made in the vicinity of a side border 3 of the bag, so that the grippable portion from the outside and elastically deformable of the strip 16 is that between the line 17 and the opposite side border 2 the more distant.
- the spacing L2 between the two welds 2a and 17 on the elastic band 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 band having a useful length at rest less than that of the opening of the bag.
- a bag having a capacity of capacity of 30 liters and a length L1 equal to about 50 cm (half-perimeter) that the connecting zone 17 is arranged so as to obtain a spacing L2 of the order of 34 cm.
- L1 capacity of capacity of 30 liters and a length L1 equal to about 50 cm (half-perimeter) that the connecting zone 17 is arranged so as to obtain a spacing L2 of the order of 34 cm.
- the degree of elastic elongation required remains less than 150% and is preferably of the order of 100%.
- the length L2 can advantageously be chosen on the order of 2/3 of L1.
- the link 6 and the strip 16 are of a different color from the color of the sheet constituting the faces 1a and 1b and the link and the strip can themselves be distinguished by different colors.
- the strip 16 made of elastic material for example ethylene vinyl acetate (EVA) is chosen so as to allow a degree of elastic elongation of less than 150%.
- EVA ethylene vinyl acetate
- the other non-elastic link 6 is, for example, made of plastic material, for example high density polyethylene.
- the bag differs from that illustrated in FIGS. 1 and 2 essentially by the fact that the elastic band 16 is connected to the skirt 4b by two intermediate connecting zones 17 and 17 ', which are symmetrical to each other with respect to a plane passing through the median recesses 12.
- the two intermediate connecting zones 17 and 17' could be arranged at different distances from the respective lateral edges 3a and 2a, without departing from the scope of the invention.
- the spacing L2 is therefore here defined between the zones 17 and 17 '.
- zones 17 and 17 ' can be provided so as to obtain a spacing L2 equal to 34 cm, each zone 17, 17' being spaced of its corresponding lateral border 3 and 2 of approximately 8 cm respectively.
- the elastic band 16 is entirely disposed on the skirt 4b, while in the first embodiment, the elastic band protruded on either side of the skirt.
- the rim of the bag at its opening is folded down on the peripheral edge of the container, as visible in FIG. 3, which advantageously makes it appear the elastic band 16 which is now oriented towards the outside of the external wall of the container.
- the elastic band is placed on the outer wall of the bag, as described below with reference to FIGS. 6 and 7, the elastic band is then hidden between the outer wall of the container and the folded rim of the bag, but the user can easily grab the elastic band by sliding his hand between the folded edge of the bag and the outer wall of the container to pull it down and fold it down on the other side of the container.
- the elastic band is shown during its elongation by the user, before he folds it on the side opposite to the container, as shown in Figure 5.
- the elastic band is at rest, while in FIG. 5 the elastic band is in its elastically elongated state, which generates a sufficient elastic force to hold the bag on container R. It is not necessary for this elastic band to be elongated until it forms a closed loop to enclose the entire periphery of the container.
- the bag 101 is essentially distinguished from the aforementioned bag 1 by the fact that the median recess 12 is optional, at least one lateral recess 112 being provided to give access to the outside the non-elastic sliding link 106.
- This non-elastic sliding link 106 is welded at one end with the side edge 2 of the bag, along the weld line 2a, while the opposite ends of the non-elastic link 106 are welded together along a weld 107 which is formed through the recess 112, so that this end of the non-elastic link 106 is not linked to the side edge 3 of the bag.
- This variant of non-elastic sliding link is known per se.
- the bag 101 could have two lateral recesses for gripping the plastic link 106, without departing from the scope of the present invention.
- Each lateral recess 112 may have any shape, in particular a quarter of a circle, a quarter of an ellipse or a rectangular.
- the bag 101 also differs in the fact that the elastic band 116 is fixed to the external wall of the face 1a of the bag, its upper edge being situated slightly above the aforementioned line 4a, while its lower edge is situated above above the lower edge of the skirt 4b.
- the elastic band 116 partially overlaps the skirt 4b and the portion of the fold 4 forming the sheath for the sliding link 106, without the link 106 and the strip 116 being able to be superimposed.
- the use of the bag 101 is substantially similar to that of the bag 1, as described with reference to Figures 3 to 5.
- the elastic band is cut or split longitudinally into two separate strands 116a and 116b, vertically adjacent and arranged, for example, on the outer wall of the face 1a of the bag.
- the strand 116a can remain, for example, on the side la of the bag, without elongation, while the other strand 116b is elongated to grip the other side of the container, analogously to the aforementioned strip 16.
- the two strands 116a and 116b form with the bag 101 a substantially closed loop around the container.
- the intermediate connection zone 117b which is subjected to a strong stress is locally reinforced by the presence of the intermediate weld 117a of the other strand 116a.
- FIGS. 6 and 7 there is shown in broken lines the additional median recess 12, thus giving access to the non-elastic link 106.
- a median recess 12 is not necessary, because the user can already access to the non-elastic link 106 by the lateral swelling 112.
- FIG. 9 represents a step in a continuous manufacturing process for a chain of bags from which the aforementioned bag 1 may originate .
- a continuous sheath of plastic film for example made of polyethylene, is scrolled on a machine, not shown, which is cut longitudinally in its center to obtain two separate half sheaths.
- each half sheath 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 recesses 12 after folding the edge longitudinal of the sheet 20 of the half sheath towards the inside, as shown in FIG. 9.
- the shape of the cut can be any, for example square, rectangular or other.
- a plastic tape 6 is introduced inside each fold 4, before closing it with a longitudinal heat seal to form the sheath.
- an elastic ribbon 16 is introduced into the sheath, along the free edge of the fold 4, overlapping it at least partially.
- the machine also performs transverse thermal welds 17 limited to the portion corresponding to the elastic tape 16 to form the aforementioned intermediate connecting zones limiting the useful length at rest of the elastic band.
- the order of the steps for producing the heat seals 4a, 2a and 3a, and 17 can be modified, without departing from the scope of the invention.
- a fifth embodiment with reference to Figure 10 in which is represented a bag 201 which is essentially distinguished from the previous bags in that it does not have a non-elastic sliding link, the bag 201 simply comprising an elastic band 216 along a side 1b of the bag, inside as shown, or outside.
- this bag 201 also includes an internal fold 4, the lower internal edge 4a of which is not necessarily welded to the rest of the bag, outside the borders side 2 and 3.
- the elastic band 216 is disposed in line with this internal fold 4, so that the limited transverse weld 217, located between the side welds 2a and 3a, is reinforced by the double thickness of material at the level of the fold 4.
- the other alternative embodiments of the elastic band illustrated with reference to FIGS. 1 to 9 are applicable to the bag 201 devoid of a plastic sliding link.
- the elastic band 216 could be cut into two strands as in FIG. 7, or alternatively provided on the outside as in FIG. 6, or else have two intermediate connecting zones as in FIGS. 3 to 5.
