Definitions
- the present invention falls within the field of packaging containers of the bottle type in batches.
- a bottle has a body with, in the upper part, a neck surmounted by an opening, called the rim. After filling, the rim is intended to be hermetically closed by a closure element, such as a stopper or a capsule. Under this stopper, for constraints related to the production of such bottles, the neck is equipped with a collar, in the form of a ring projecting externally with respect to the peripheral wall of said neck.
- Such a collar serves in particular as a support in abutment against the upper face of the mold during the manufacture by blow molding or by stretch-blow molding of a bottle from a preform made of plastic material, as well as for the conveying and transfer of such a preform and such a bottle throughout a production line.
- a bottle can be made of any type of material, in particular plastic, metal or even glass.
- a bottle can be rigid or semi-rigid.
- Such a bottle is intended to contain, in a non-exhaustive manner, a fluid, a liquid, in particular of the food-processing or cosmetic type.
- a bottle can have any type of shape, symmetrical or not, regular or irregular.
- a bottle can have a rounded section, generally circular or ovoid in shape, or else a polygonal section, in particular rectangle or square.
- the bottles can receive several different successive treatments, such as the manufacture of the container, for example during a plastic injection or stretch-blow molding operation in the case of a plastic bottle, followed by filling then closing with a cap and labelling.
- the containers are said to be "finished”. With a view to handling them, such finished containers are packaged in batches.
- each batch comprises several bottles, grouped together in a matrix arrangement, generally of generally parallelepipedic shape, often square or rectangle, according to columns and rows.
- a usual batch gathers six bottles in two rows and three columns.
- each group of bottles can be held below by means of a support forming a bottom, for example a cardboard tray.
- each group can be coated, in particular covered with a film, in order to hold the bottles together and to facilitate the handling of such a batch thus obtained.
- Such a coating can be carried out through a filming or preferably wrapping step.
- wrapping a group of bottles consists of wrapping it with a sheet of plastic film made of heat-shrinkable material.
- a coated group then undergoes a heating step so that the sheet conforms to the overall external shape of the bottles.
- the sheet of film shrinks under the effect of heat to form a constriction ensuring the maintenance of the grouped bottles.
- the grouping of the bottles, the coating and the heating are carried out by means of a dedicated installation of the bundler type, through several successive stations. Further, the heating of a coated group is carried out by crossing a heating station; like an oven, tunnel oven type. Each group of bottles is transported on the upper face of one or more conveyors, from the entrance to the exit of said oven.
- hot air is sent to the conveyor from below and allows to heat the underside and the lower edges of the groups transported on the conveyor, essentially aiming at the part of the film sheet located under each group of bottles , in particular to weld the ends of the coating sheet which, at the time of the prior coating, are superimposed and pressed against each other under the weight of the bottles of the group.
- hot air is sent to the interior volume of the enclosure and makes it possible to heat the coated group, with a view to effecting a rise in temperature of the sheet of film so that a shrinkage comes apply in contact with the bottles, by deforming the sheet so that it matches part of the contours of said bottles.
- heating installations especially in the form of tunnel kilns, represent a substantial footprint within an industrial production site.
- the coating is carried out using a film of plastic material, essentially obtained from the petrochemical industry.
- plastics can be composed of material improving their biodegradable character.
- the recycling and recovery of plastic waste is constantly evolving.
- a known alternative consists in holding a group of bottles by strapping or strapping by means of ties made of plastic or composite material, in particular in the form of a strip of braided plastic fibers.
- ties made of plastic or composite material in particular in the form of a strip of braided plastic fibers.
- Such a strip surrounds the body of the bottles and tension is applied before sealing the ends of said strip, in particular through a heat-sealing operation. If the use of a band saves a considerable amount of plastic material, the strapping does not make it possible to properly maintain batches of more than four bottles, especially when it comes to containers with a rounded section, whether it is generally circular or ovoid, which is more in the case of containers made of plastic material.
- plastic material of a strap is provided more resistant, making it all the more difficult to reprocess it for recycling.
- a coating based on vegetable fibers such as a cardboard material, in particular in the form of a pre-cut cardboard sheet, hereinafter referred to as "die-cut”.
- a widely used solution consists of a cutout in which through orifices are provided with internal segments forming bendable fringes extending radially inward from each of the orifices.
- Such orifices are intended to receive by force insertion the closure elements closing the bottles to be kept in a batch. In particular, the insertion takes place vertically, the bottles coming from below push back said fringes, until they are clipped.
- This technique specifically targets glass bottles closed by a closure element in the form of so-called “crown" capsules (for
- the rest of the sheet is then folded over to surround two of the side walls of the batch thus formed, the ends of said sheet generally being glued or snapped overlapping at the level of the underside of said batch, namely under the bottles thus grouped together.
- the aim of the invention is to overcome the drawbacks of the state of the art by proposing an alternative solution for maintaining a batch of bottles by means of a cutout in paper or cardboard material.
- the invention provides a cutout whose insertion is carried out by vertical displacement of the cutout followed by a displacement in a lateral direction of the bottles, sliding in sliding inside orifices shaped complementary for, in a first step, allow the free insertion of the caps and the collars of the bottles, then ensure a vertical maintenance once the caps of the bottles close together, by abutment of the said collars against the surface of the cutout.
- the invention ensures that the bottles are held together laterally, limiting any freedom of movement in the opposite direction along said transverse direction of insertion, namely in the spacing of said bottles.
- the invention has highlighted a superfluous aspect of the coating along the side walls of the bottles.
- a bending effect causes the separation of said bottles, which essentially results in the lower part of the lot.
- the conditioning device comprises

- the present invention falls within the field of the packaging in batch 1 of containers 2 of the bottle type, hereinafter referred to as “container” or “bottle” in an equivalent manner.
- a container 2 of the bottle type has a body 20 with in the upper part a neck surmounted by an opening, called a mouthpiece. After filling, the rim is intended to be hermetically closed by a closure element, such as a stopper 21 or a capsule. Under this stopper 21, for constraints related to the production of such bottles, the neck is equipped with a collar 22, in the form of a ring projecting outwardly with respect to the peripheral wall of said neck.
- Such a collar 22 serves in particular as a support in abutment against the upper face of the mold during the manufacture of a bottle by blow molding or by stretch-blow molding from a preform made of plastic material, as well as for the conveying and transfer of such a preform and such a bottle all along the production line.
- the collar 22 constitutes a rigid and solid part of the container 2. This collar 22 can also be standardized.

- a bottle can have a rounded section, generally circular or ovoid in shape, or else a polygonal section, in particular rectangle or square.
- the bottles can receive several different successive treatments, such as the manufacture of the container, for example during a plastic injection or stretch-blow molding operation of a preform in the case of a bottle made of plastic material, followed by filling then closing with a cap 21 and labeling.
- the containers 2 are said to be "finished”. With a view to their handling, such finished containers 2 undergo packaging in batch 1.
- each batch 1 comprises several bottles, grouped together in a matrix arrangement, generally of generally parallelepipedic shape, often square or rectangle, according to columns and rows.
- a usual lot 1 groups together six bottles in two rows and three columns.
- Figure 1 shows a batch 1 of two containers, in one column and two rows (or vice versa), while Figures 2 and 3 show a batch 1 of four containers, configured in a square matrix, in two columns and two rows.
- the containers 2 must be held together to form a batch 1 .
- the invention firstly relates to a device 3 for packaging in a batch 1 of at least two containers 2.
- said containers 2 are bottles with a neck provided with a collar 22 having a first diameter, namely a diameter larger than the outside diameter of the neck, so that said collar 22 forms an annular projection.
- Such a packaging device 3 comprises a sheet 4 of cardboard material.
- a cardboard material includes paper and cardboard, as well as any material based on plant cellulosic fibers.
- the material of the sheet 4 is devoid of plastic or of a material obtained from the petrochemical industry.
- a layer or coating can be applied to the outer and/or inner face of sheet 4, in particular of the printing, varnish or waterproof type.
- This material can be single or multilayer material.
- the thickness of said sheet 4 is minimal, compared to its other dimensions, namely its length and its width.
- said sheet 4 is determined with regard to the number of containers 2 to be maintained, as well as certain characteristics of said containers 2, such as in particular their format and their weight.
- said sheet 4 has a sufficient thickness to impart rigidity to the containers once held by the packaging device 3.

- said sheet 4 comprises at least four orifices divided into a matrix. This configuration can be seen in particular in FIGS. 2 and 3. According to another embodiment, said sheet 4 comprises six orifices distributed according to a rectangular matrix. This configuration is particularly visible in Figures 4 to 7.
- the dimensions of an orifice 5 are determined according to the container 2 to receive, in particular with respect to the dimensions of the neck of said container 2, especially with respect to a first diameter of said collar 22. Indeed, each orifice 5 is intended to receive the neck of the containers 2 for insertion, so that said sheet 4 holds the containers 2 together by their necks in a batch 1 after insertion.
- each of said at least two orifices 5 is oblong.
- each orifice 5 has a longitudinal median axis longer than a transverse median axis (extending orthogonally or substantially orthogonally with respect to said longitudinal axis).
- each orifice 5 comprises a first section 50 at least greater than or equal to the first diameter of said flange 22.

- a container 2 has only one horizontal degree of freedom from the second section 51 to the first section 50.
- each orifice 5 is open, namely that it communicates with an edge of the sheet 4. More specifically, the first section 50 of larger diameter opens towards the outside of the conditioning device 3.
- Such an open configuration makes it possible in particular to insert the containers 2 by the side of the sheet 4, without vertical displacement of said containers 2 and/or of said sheet 4.

These side flaps extend in a direction along a central axis passing through said first section 50 and said second section 51 of at least one of said at least two orifices 5. In other words, the side flaps are positioned on each side of the sheet 4, on either side of the orifices 5. In short, the side flaps are located at the edge of the sheet 4 , orthogonally or substantially orthogonally to a median axis passing through said at least two orifices 5.
- said sheet 4 includes a downward folding line of each of said side flaps.
- the dimensions of the flaps depend on the dimensions of the containers 2 to be maintained. Once folded, these flaps come into contact with part of the containers 2, in particular their neck, their body and/or the junction between the neck and the body.
- each fold line crosses the first section 50 of at least one of said orifices 5.
- a fold line crosses each longitudinal alignment of orifices 5. Therefore, the folding of the sheet 4 makes it possible to close the first section 50 of the orifices 5, maintaining the containers 2 within the second section 51 .
- said side flaps comprise two longitudinal flaps 6, namely that they extend along the length of the sheet 4. Such longitudinal flaps 6 are particularly visible in Figures 5 to 7.

- said at least two orifices 5 are spaced apart by an interval greater than a center distance between said containers 2.
- the sheet 4 comprises several central folding lines. Each centerline extends longitudinally.
- center distance corresponds to the distance between the axes of revolution of two containers 2 placed side by side, namely approximately the diameter of a container 2.
- the interval is greater than or equal to said spacing, preferably greater than or equal to two spacings.
- the sheet 4 comprises a central central folding line 9 and two central central lines 90 located on either side, parallel and equidistant from said central line 9.

- the folding is carried out downwards, namely downwards, by lowering the center line 9.
- the part of the folded sheet 4 then forms an intermediate wall 11 between the receptacles 2.
- Such an intermediate wall 11 makes it possible in particular to serve as a buffer between the receptacles 2, avoiding their direct contact and improving the horizontal maintenance between them, due to the folding extra thickness of said sheet 4.
- side flaps can be combined with the aforementioned central folding, in order to improve the maintenance of the lot 1 thus formed.
- the packaging device 3 comprises gripping means.
- gripping means can be attached externally and independently to said device 3.

- the strip 100 and/or the tray 101 maintain the periphery and/or the bottom of the containers 2, in particular under their center of gravity, preventing any separation in the lower part of said containers when gripping the batch 1 from the top, ensuring improved maintenance of the packaging device 3.
- batch 1 may include gripping means, in order to ensure the handling of each batch 1 independently.
- gripping means can be of any type, in particular in the form of a handle attached for attachment to one and/or the other of the containers 2 of batch 1, in particular by gluing along the body 20 of said containers 2 and/or on some of the outer faces of the packaging device 3.
- said gripping means are integrated into the packaging device 3 .
- This configuration corresponds to the embodiments of the packaging device 3, in which the gripping means comprise the holes 12 made in the sheet 4, in particular communicating with each of the orifices 5.
- the invention also relates to a process for packaging in batch 1 of at least two containers 2.
- said containers 2 are bottles with a neck provided with a flange 22 of a first diameter.
- said neck has a second diameter smaller than said first diameter of said collar 22.
- a sheet 4 provided with at least two orifices 5 is deposited.
- each orifice 5 is oblong and comprises a first section 50 at least greater than or equal to said first diameter of collar 22, as well as a second section 51 less than said first diameter.
- the neck of each of said at least two containers 2 is inserted vertically within each of said at least two orifices 5 through said first section 50, until said sheet is positioned under a horizontal plane comprising said collar 22.
- the collar 22 crosses the first section 50 until it ends up above the sheet 4.
- the containers 2 are then held vertically, having only one degree of freedom of transverse movement back from the second section 51 to the first section 50.
- said at least two containers 2 are held together at least in a direction opposite to said horizontal transverse direction.
- such maintenance can be operated by dedicated bodies, similar to the bodies of said packaging device 3 or related reported on lot 1, such as a strip 100 or a tray 101.
- the insertion of the containers 2 through the first section 50 can be carried out by a "relative" vertical displacement between said sheet 4 and the containers 2, namely by displacement downward vertical movement of said sheet 4 with respect to the receptacles 2, by upward vertical displacement of the receptacles 2 with respect to the said sheet 4, or else by a combination of vertical movements of the said sheet 4 and the receptacles 2.
- This insertion can also be provided only by horizontal displacement of each of said containers 2, coming to be introduced transversely within the orifices 5 correspondents.
- Such a horizontal displacement takes place in a direction substantially parallel to the plane of the sheet 4, in particular horizontal or substantially horizontal.
- This horizontal displacement takes place parallel or substantially parallel to the longitudinal central axis of the elongated orifices 5 which are then open.
- Said insertion can also be a combination of relative vertical displacement and horizontal displacement.
- the removal of the sheet 4 can be carried out in a synchronized manner with the conveying of the containers 2.
- the removal of the sheet 4 can also be done continuously by following the progress of the containers 2, or else discontinuously, by temporarily stopping the containers 2 which are capped by the sheet 4 during this period of time.
- open orifices 5 it is also possible to come down a sheet 4 to a suitable level, the containers 2 being conveyed along a converging path to be introduced into each orifice 5. This mode of removal considerably simplifies the operation of the method, freeing itself from any vertical displacement.
- the second sections 51 of said at least two orifices 5 are oriented towards a median axis of said sheet 4. Therefore, during the movement, said containers 2 are applied a movement towards convergent towards said median axis. In short, the containers 2 are brought closer to the center of the sheet 4.
- said first sections 50 of said at least two orifices 5 are oriented towards a median axis of said sheet and spaced apart by an interval greater than a center distance between said containers 2. Therefore , during movement, said receptacles 2 are moved apart in a divergent manner with respect to said central axis.
- folding may occur along fold lines 9,90, similar to the above.
- a wall 10 projecting upwards is formed from said interval of said sheet 4.
- a projecting wall 10 can make it possible to form a handle, in particular provided with holes mentioned above, said holes 12 being connected or not in a communicating manner with some of the orifices 5.
- a descending manner is formed intermediate wall 11 from said interval, said intermediate wall 11 coming between said containers 2.
- the flaps 6 of the sheet 4 comprise cut sides. On the edges of the flaps 6, a flat surface forms the contours. In this type of construction, each corner of the flaps 6 no longer forms a right angle but two obtuse angles. Thus, when the transverse flaps 60 are fixed with the adjacent longitudinal flaps 6 with the fixing means 8, they then follow the outer contour of the containers 2 located at the corners of the lot 1 .
- This type of construction is particularly advantageous because the cut sides formed by the flaps 6 and 60 allow better retention of the containers 2 and therefore to optimize the packaging device 3. Indeed, the flaps are then also in contact with the containers 2 at the corners of the lot 1.
- the packaging device 3 is more reliable and the solidity of batch 1 is improved: the absence of sharp edges reduces the risk of deformation of batch 1.
- this embodiment makes it possible to optimize the palletization step, in particular by limiting the potential tearing of the film in the corners, by improving the hold of the palletization film.
- the sheet 4 comprises fringes 14 which match the shape of the first section 50 communicating with the second section 51: a plurality of fringes 14 extend radially from the center of the first section 50, up to at the opening of the second section 51 .
- the fringes 14 take the form of bendable inner segments extending radially inward from the second section 51 .
- the sheet 4 comprises pre-cuts 15, in order to be able to facilitate the removal of a container 2 individually.
- the pre-cuts extend from the median axis of the sheet 4 in the longitudinal direction to the edges of said sheet 4.
- the pre-cuts 15 extend from the second section 51 to the edges of the sheet 4.
- the pre-cuts 15 can then extend from the median axis of the sheet 4 in the longitudinal direction to the edges of said flaps 6. They can also extend from the first or the second section (50, 51) to the edges of the flaps 6.
- pre-cuts 15 are for example in the form of dotted lines, which correspond to micro-perforations making it possible to tear said sheet according to a precise and determined path.
- the pre-cuts 15 are made to form lines of rupture or of lesser resistance of the material, favoring tearing along said lines in the event of voluntary tension or torsion.
- This embodiment is particularly advantageous because it facilitates removal from the container unit 2 when desired, that is to say intentional.
- this makes it possible, according to a possible alternative, to retain certain information printed on the sheet 4 even when a container 2 is made unitary, that is to say after the sheet 4 has been intentionally torn and the said container 2 has been removed.
- information may for example be a barcode, a logo, a brand, or may even relate to the nutritional characteristics of the drink or other content of said container 2.
- the packaging device according to the invention advantageously makes it possible to obtain a batch 1 of 2 strong and reliable containers.
- the containers 2 are both well maintained by means of the sheet 4 and can be removed voluntarily if necessary.
