Description

[0001] DESCRIPTION

[0002] Title: Bottle made from recyclable materials other than glass

[0003] FIELD OF THE INVENTION

[0004] The present invention relates to a bottle made from recyclable materials other than glass.

[0005] The term "bottle", according to the present invention, encompasses all forms of containers having a cylindrical body ending in the upper part with a neck connected to the body by a transitional zone forming the shoulder.

[0006] STATE OF THE ART

[0007] Containers are known made of materials more economical than glass, formed from a rigid shell corresponding to the shape of a bottle and the cavity of which is occupied by a flexible, waterproof pocket, receiving the liquid or, more generally, the fluid or pasty product, packaged in the bottle for example according to document US 4,256,231.

[0008] But, in general, these bottles, flasks or others are made from combinations of materials that are difficult to separate for recycling and therefore ultimately not recyclable.

[0009] PURPOSE OF THE INVENTION

[0010] The present invention aims to develop a bottle made of materials or materials other than glass, recyclable, easily separable, and usable like traditional bottles, in filling and packaging installations such as bottling lines, crates or bottle transport racks which facilitate recycling by the simple separation of the components of the bottle intended for different recycling.

[0011] DISCLOSURE AND ADVANTAGES OF THE INVENTION

[0012] To this end, the invention relates to a bottle made of recyclable materials other than glass, composed of a rigid shell receiving a flexible pocket delimiting the sealed volume of the bottle with a nozzle fixed to the shell and receiving a closure means such as a stopper or capsule, characterized in that it comprises a bottle structure formed by a cylindrical sleeve whose upper end is terminated by a part shaped like a shoulder and a neck, externally receiving a sheath of fibers of natural origin fixed at least in the upper part and in the lower part to the bottle structure, a bottom of the bottle structure closed by a bottom embedded in the lower edge of the sleeve of the bottle structure and, a nozzle forming the neck terminated by the neck and to which is secured a flexible, sealed pocket, coming inside the bottle structure to receive the contents, and the nozzle being engaged in the neck formed by the structure.

[0013] In particular, the cylindrical body-shaped bottle structure is connected by an intermediate surface to the neck, the cylindrical body being formed by a cardboard tube,

[0014] - the tip consists of a molded part engaged in the neck of the bottle structure to which it is fixed,

[0015] And in particular the end of the sleeve has a notch cut-out releasing narrowed slats to form the intermediate surface constituting the shoulder and the neck of the bottle structure.

[0016] The invention has the advantage of developing a bottle that is very simple to manufacture, suitable for all installed bottling lines. This allows the bottle according to the invention to be used like a glass bottle. The bottle is particularly simple to recycle thanks to the materials that compose it and the ease and simplicity of disassembling the bottle into its components to be recycled separately.

[0017] The bottle also has the advantage of ensuring good thermal insulation or, in other words, of regulating the temperature of the contents thanks to its cardboard structure.

[0018] The bottle being completely opaque, it avoids disturbances and alterations of the contents. Finally, recycling, as already mentioned, is done only on two channels, that of cardboard and that of plastic material.

[0019] Separation of the two components of the bottle for recycling is facilitated by the fact that the plastic cap is equipped with an extraction collar which allows the flexible bag with its cap and its plastic sleeve constituting the end piece to be separated from the cardboard body. The tab is preferably integrated into the closure means of the plastic bag.

[0020] The bottle, according to the invention, is adaptable to multiple bottle shapes, of circular but also polygonal, square, rectangular, or even triangular section; the polygonal sections can have 5, 6 sides while retaining the appearance of an existing bottle or close to an existing one or even of an original bottle while recalling or suggesting existing shapes.

[0021] All this diversity of shapes is compatible with existing assembly lines processing glass bottles.

[0022] This multiplicity of forms in no way reduces the advantages of simplicity of manufacture, compatibility with existing installations and costs as well as recycling possibilities.

[0023] Particularly advantageous for manufacturing, use and recycling, the sheath is braided or knitted from natural fibers.

[0024] This sheath is in itself elastic or deformable, adapting to all possible shapes of the bottle structure with which it must be associated.

[0025] Advantageously, the lower end of the bottle structure coated with the sheath is closed by a cup-shaped bottom made of stamped cardboard.

[0026] This allows for a precise bottle support surface. Such a surface is important for the use of bottling lines as well as for all industrial operations to which the bottle may be exposed.

[0027] Generally, the cylindrical body formed by the sleeve is of circular, oval or polygonal section.

[0028] Characteristically, the lamellae of the crenellated edge of the end of the sleeve consist of a trapezoidal-shaped sector, the large base of which remains connected to the sleeve and the small base of which continues with a tongue whose width corresponds to a fraction of the periphery formed by the edge-to-edge junction of the lamellae constituting the neck.

[0029] The shape of the notches allows multiple shoulder and neck shapes to be created by simply tracing the notches forming the slats.

[0030] Advantageously for shaping the shoulder and neck, the junction between the lamella and the sleeve body is formed by a base fold line.

[0031] In particular, the junction between the small base of the sector of a lamella and the tab is made by a folding line. And also, the sector is provided with transverse folding lines facilitating the shaping of the sector constituting the shoulder of the bottle structure.

[0032] According to another interesting feature, the bottle structure is composed of the cylindrical sleeve forming a cylindrical body and a cap in the upper part, shaped as a shoulder and neck of the bottle and fixed to the body.

[0033] Or, the tip is composed of an inner tube bordered in the lower part by a skirt delimiting a peripheral interval to overlap the upper edge of the neck of the bottle structure and be fixed there.

[0034] According to a particular form, the tip forms two internal necks associated with two flexible pockets, distinct and independently accessible and having distinct means of closure.

[0035] The tip forming a particular shape, the tip forming two necks has the advantage of allowing the bottle to be used to receive two liquids which must be supplied separately to then be used separately or even in certain combinations.

[0036] This "double bottle" retains all the advantages of the above bottles and characteristics because this double bottle fits into the contour of a usual bottle and can thus use the manufacturing and bottling lines of usual bottles, with the exception of the filling part which requires adaptation for filling each of the pockets with a liquid or more generally a separate fluid.

[0047] DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0048] By convention and to simplify the description, the vertical orientation is that of a standing bottle:

[0049] - the collar is at the upper end,

[0050] - the bottom is at the lower end.

[0051] The bottle rests on the bottom when standing upright.

[0052] According to Figure 1, the invention relates to a bottle 100 made from recyclable materials or materials other than glass. This bottle 100 is composed of a cylindrical sleeve 200 whose end 210 forming the upper end of the future bottle is deformed to produce the shoulder B and the neck C of the bottle by cutting crenellations 11 releasing strips 2 which, by deformation by compression and joining edge to edge, constitute the shoulder B and the neck C of a bottle structure SB.

[0053] This bottle structure SB is then covered by a sheath 3 of natural fibers, that is to say natural fibers as such or derived from natural fibers. The sheath 3 is impregnated with resin securing the assembly of the fibers and their attachment to the bottle structure. It can also be glued to the bottle structure SB. This assembly constitutes a bottle blank EB receiving a flexible bag 5 connected to a nozzle 4 forming the neck G. This nozzle 4 is fitted into the upper end of the shaped bottle structure SB and secured to it. The volume of the flexible bag 5 is substantially that of the cavity of the bottle structure SB.

[0054] The lower edge 32 of the sheath 3 is folded into the cavity around the lower edge 211 of the sleeve 200, thus constituting the neck of the bottle. The folded edge 32 is fixed to the structure SB by the impregnation resin or by gluing.

[0055] The bottom F of the blank EB is closed by a cup-shaped part 6, preferably made of stamped cardboard, engaged in the bottom F of the bottle structure SB with the hollow facing outwards. The jable is thus left clear to have a regular support crown, guaranteeing the stability of the upright bottle. This bottom forming a stable support is an essential condition for the compatibility of the bottle to pass through existing bottling lines, not requiring exceptional and expensive means.

[0056] The bottle manufacturing process will be described below, using figures 2, 3.

[0057] According to Figure 2, from the cylindrical sleeve 200 made of cardboard or other recyclable material, of this type, cut into a tube and corresponding to the shape of the future bottle by its section and its height, notches 11 are cut into one 10 of its ends. The notches 11 leave strips 2 composed of a sector 21 of trapezoidal shape extended at its small base 212 by a tab 22. The strips 2 are joined at their base connecting them to the remainder of the strictly cylindrical sleeve 200 forming the body 1 of the bottle 100.

[0058] As an example and for usual bottle sections of the order of

[0059] 10 cm, the number of slats 2 is 5 or 6.

[0060] These strips 2 remaining between the notches 11 in the end zone of the sleeve, have simple contours, delimited by the notches

[0061] 11 cut into a point shape; they leave lamellae 2 joined at their origin on the sleeve. The lamellae 2 are compressed concentrically towards the axis ZZ of the sleeve to join edge to edge and form the upper circular edge 222 (pseudo circular) constituting the neck and imposing the shape of the shoulder B produced by the assembly of the trapezoidal sectors 21.

[0062] The strips 2 are thus assembled in a jointed manner edge to edge. The assembly of the tabs forms the neck part C while the sides of the trapezoidal sectors form the shoulder B of the bottle structure SB.

[0063] In the simplest case, the sides 213 of the trapezoidal sectors 21 are straight so that their assembly side by side forms a truncated cone. If the sides 213 are convex, the assembly of the sectors 21 forms a domed crown (or convex toric) from which the tongues 22 emerge.

[0064] Conversely, if the sides 13 are concave, the assembly of the sectors 21 is a concave toric surface from which the tongues 2 start, assembled edge to edge to form the cylindrical neck C. The height of the sectors 21 defines the more or less compacted shape of the shoulder B of the bottle. To impose the precise shape of the shoulder B and the neck C, the junction of the strips 2 to the body 1 is underlined by a base line 12 of folding, more or less accentuated to favor the curvature of the sectors 21 relative to the body 1. In the same way, the junction between the end of the sectors 21 and the tongues 22 will be underlined by a transverse fold 221 re-entrant.

[0065] The rigidity of the sectors 21 can also be reduced by circular transverse folding lines 214. The bending of the tabs 22 to fit a neck-shaped section, of smaller curvature than that initially of the sleeve 200 from which the strips 2 are cut, is facilitated if the tabs 22 are weakened by one or more longitudinal folding lines 223, parallel to the axis ZZ.

[0066] The slots can be cut out advantageously using a punch.

[0067] The cutting line, i.e. the contour of the notches, is defined according to the curved surface to be made for the shoulder and the junction towards the neck. The shape of the shoulder and neck of the bottle will be obtained from the cut blank, by deformation by folding using the combination of a form and a counterform.

[0068] The deformation can be carried out hot using the form and the counter-form equipped with heating means. This hot deformation makes it possible to soften the transition between the forms and generate a memory of the material avoiding any tearing phenomenon.

[0069] Figure 3 shows the joining of the lamellae 2 to form the shoulder B and the neck C of the bottle structure SB. The lamellae 2 are tilted towards the ZZ axis of the sleeve to assemble them edge to edge. This state can be stabilized by temporary bonding to allow the installation of the fiber sheath 3 on the bottle structure SB and the impregnation and bonding to this structure. A bottle blank EB is obtained that is rigid to axial compression and radial compression, compatible with the forces to which a bottle is usually exposed during its lifetime, from filling and passage through a bottling line to the rest of the handling and transport.

[0070] The next step is the production of the complete bottle from this blank EB by combining it with the end piece 4 and the flexible bag 5. Generally, the sleeve 200 is a cylindrical sleeve, that is to say a cylindrical surface, for example, of circular section. But this section can also be of another shape, for example, with a closed curved directrix, oval or polygonal, regular or irregular, such as a square, a rectangle, a polygon with an even or odd number of sides, generally between three and six sides.

[0071] In the case of a polygonal sleeve, the notches 11 are cut taking into account the position of the edges for the shape of the facets of the shoulder B and that of the cylindrical neck C of circular section, ending in the neck.

[0072] An oval or polygonal cardboard sleeve is made like a cylindrical sleeve with a circular section, by rolling several layers of paper in a helical pattern, over a corresponding oval or polygonal section.

[0073] Sheath 3 is made of natural or naturally occurring fibers; it is a deformable tubular piece, braided or knitted. The fiber is, for example, a linen fiber.

[0074] The flexible, leak-proof bag 5 is a plastic bag, neutral with respect to the liquid or fluid to be received; in the case of a bottle intended for a food product, the bag is food grade.

[0075] The end piece 4 is a molded plastic part forming the neck G. In general, the neck G is intended to be closed by a closure member such as a stopper or a capsule screwed onto the thread of the end piece or clipped on like a “crown” capsule.

[0076] The end piece 4 can also have a double neck fitting into the circular contour of the circular end piece. This double neck is then connected to two separate flexible pockets to receive two different liquids, complementary or not. The necks G have a separate closure member, for example, a stopper. But, the end piece 4 can also be equipped with pouring spouts provided with a plug thus facilitating the dosing of liquids from the bottle. Alternatively, the end piece 4 with a single or double neck can receive one or two pouring spouts.

[0077] In the case of two complementary liquids which only need to be mixed when used, the volume of the bags 5 will preferably be a function of the mixing ratio of the two liquids or fluids.

[0078] Alternatively, the two separate pockets can also be combined into a pocket 53 subdivided into two separate volumes 51, 52. Figures 4A, 4B, 4C are very schematic axial half-sections of the main steps in producing the bottle 100 according to the invention.

[0079] According to Figure 4A, a sleeve 200 is used, cut to the appropriate length from a cylindrical tube, in particular a commercial one, for example made of rolled paper, with a diameter of the order of 7 to 10 centimeters. The sleeve is cut to the length necessary to obtain the bottle structure SB as will be described below. The upper end 210 of the cylindrical sleeve 200 is cut with crenellations 11 forming a body crowned with lamellae 2, which will be folded towards the axis ZZ to form the shoulder B and the neck C of the bottle or more precisely at this stage, of the bottle structure SB.

[0080] According to Figure 4B, the bottle structure SB thus formed receives the sheath 3, the ends of which are folded into the neck C and into the rim to be fixed by gluing or by coating the sheath with a resin. In the case of gluing, the sheath 3 is glued not only at the ends, but also at various intermediate points.

[0081] According to the other variant, the sheath 3 is coated with a resin which reinforces it and fixes it over the entire surface of the SB bottle structure, thus forming a lightweight assembly but very resistant to compression forces and having insulating properties.

[0082] In all cases, the sheath 3 is part of the bottle 100 and receives externally covering elements such as a body label, a back label and, where appropriate, a neck label. The sheath 3 must be integral with the structure of the bottle and not slide, even locally, relative to it when the bottle is held. This produces a bottle blank EB with its structure SB itself already rigid by its shaping and completed by its combination with the sheath 3.

[0083] According to Figure 4C, the bottle blank SB thus prepared then receives the end piece 4 integrally provided with the flexible bag 5. The end piece 4 is very schematically an inner tubular part 41 forming the inside of the neck and bordered by an outer skirt 42, forming a peripheral gap 43 to overlap the upper edge 222 of the neck of the bottle structure SB, leaving a cylindrical part 44 forming the neck and its “ring” receiving a stopper 7a engaged in the tube 41, or a capsule 7b screwed onto the outer thread of the end piece or clipped onto it. The bag 5 fixed to the end piece 4 plunges freely inside the bottle structure SB.

[0084] The bottom F of the bottle 100 is constituted by a cup 6, preferably made of stamped cardboard, engaged in the rim of the bottle structure SB. The cup 6 is glued by its edge 62 to this structure with the interposition, if necessary, of the lower edge 32 folded back from the sheath 3. The cup 6 is fixed in the bottle structure SB in the inverted position to complete the rim, its bottom 61 being turned towards the inside of the body 1.

[0085] Figure 5 is a very schematic sectional view of an example of a tip 4 composed of a tubular sleeve, with a skirt forming a peripheral gap to overlap the upper edge 222 of the bottle structure SB. The interior of the tip carries the flexible pouch 5.

[0086] According to Figure 5, the first embodiment of the end piece 4 is composed as described of a cylindrical tube 41 provided, in the lower part, with a skirt 42 forming a peripheral gap 43 for fitting the end piece onto the upper edge of the neck C of the bottle blank EB for fixing by force or by gluing. The top of the tube 41 forms the ring of the neck G to receive the stopper 7a or alternatively, a screwed or crimped capsule 7b.

[0087] Figure 5A is a schematic sectional view of a variant of nozzle 4a with twin necks Gl, G2 forming two separate passages associated with two single pockets 51, 52 or with a double pocket 53 subdivided into two independent volumes, each associated with a respective neck Gl, G2. These necks Gl, G2 can each be provided with a separate pouring spout. The closure of the two necks Gl, G2 is independent.

[0088] Figure 6 is an exploded sectional view of another embodiment of a nozzle 4b. The nozzle 4b is composed of two parts: - a base 45 in the form of a sleeve 451 provided with a collar 452 and a skirt 453 to be engaged or fixed in the neck G of the bottle structure SB, and

[0089] - a neck 46 engaged in the base 45 and receiving the screwed or clipped cap or capsule.

[0090] The base 45 has a clipping rib 454 and is connected to the bag 5. The base 45 is preferably attached to the bottle blank EB under manufacture to then be combined with a neck. The entrance of the base 45 is preferably covered by a cover protecting the interior of the bag during all operations preceding filling and bottling.

[0091] The neck 46 has a shape complementary to that of the base 45 in order to be clipped therein. For this purpose, the neck 46 has a body 461 provided with a clipping groove 462 and a raised lower edge 463 in order to hook under the lower edge of the base 45, the groove 462 clipping onto the rib 454.

[0092] The neck 46 has a threaded ring 464 receiving a stopper or a capsule 7a, b.

[0093] The neck 46 can be personalized by the packager with a mark or an indication of the contents packaged in the bottle received from the manufacturer with the base 45 and the pocket 5 placed in the bottle blank EB.

[0094] According to a variant, the neck is made integrally with the stopper 7a, b and this assembly is forcibly engaged in the base 45 after the bottle has been filled so as to constitute a tamper-evident assembly.

[0095] The cap physically connected to the neck is detached by a movement, for example, of rotation to cut the links with part 46.

[0096] Figure 7 shows another embodiment of the SBA bottle structure according to the invention, composed of a body 1 in the form of a cylindrical sleeve, for example, of circular section, and a cap 13 in the upper part forming the shoulder B and the neck C. This cap 13 e, in the form of a straight or domed truncated cone, continues in a single piece with the neck. The assembly is, for example, made of molded cardboard or other recyclable material. The lower end 131 of the cap 13 is formed of a collar which engages and is fixed in the cylindrical part constituting the body 1.

[0097] The bottom of the SBA bottle structure is closed with a cup 6, for example, made of stamped cardboard, and fixed in the cylindrical body 1.

[0098] The pocket 5 is fixed inside the truncated cone-shaped part of the hat 13.

[0099] The assembly in the form of a SBA bottle structure is thus dismantled by separating the cylindrical sleeve 1 and the cup 6 from the cap 13 to which the pocket 5 remains connected. The SBA bottle structure receives a sheath 3, not shown, which is glued or fixed by application. The sheath 3 is a braided or knitted sheath made of natural fibers.

[0100] According to a variant of the bottle structure composed of the cylindrical body 1, the truncated cone-shaped cap 13 forming the shoulder B and the cylindrical neck C and a base F constituted by a stamped cup 6. The body 1 and the cap 13 are assembled without the pocket which, in this case, is integral with a nozzle engaging in the upper part of the neck. This version is not shown.

[0101] In summary, the invention relates to a bottle made of recyclable materials other than glass, composed of a rigid shell receiving a flexible pocket delimiting the sealed volume of the bottle and a tip fixed to the shell and receiving a sealing means such as a stopper or capsule,

[0107] According to the invention, the sheath 3 is braided or knitted from natural fibers.

[0108] In particular, the lower end of the bottle structure SB coated with the sheath 3 is closed by a cup-shaped bottom 6 made of stamped cardboard.

[0109] Furthermore, the cylindrical body 1 formed by the sleeve 200 is of circular, oval or polygonal section.

[0110] According to another variant, the strips 2 of the crenellated edge of the end 210 of the sleeve 200 are composed of a sector 21 of trapezoidal shape, the large base 211 of which remains connected to the sleeve 200 and the small base 212 of which is continued by a tongue 22 of which the width corresponds to a fraction of the periphery formed by the edge-to-edge junction of the strips 2 constituting the neck C.
