Definitions
- the present invention relates to a bottle formed of a wall comprising a bottom, a body and a neck.
- the invention also relates to a method for producing such a bottle.
- the bottle according to the invention corresponds to a generic term encompassing all shapes of bottles, flasks and jars generally made of glass or plastic, whether these shapes are rotationally symmetrical or not, of round, rounded or polygonal section, varying from the bottom towards the neck opening.
- All these bottles have a shape in general between the bottom and the openings of the neck comprising a flat bottom or provided with a puncture, a body joining the neck by a shoulder and provided with a ring or a screw or screw ring capsule to receive a stopper, capsule or lid.
- the different parts of the bottle are more or less accentuated or attenuated, a more or less high body, a more or less marked shoulder, a more or less long neck and a ring or other relief to receive a body of closure such as a stopper or a capsule or a screwed or clipped lid.
- the bottles, flasks, jars traditionally made of glass have multiple shapes and sections.
- the disadvantage of glass bottles is their manufacturing process requiring high temperatures for melting and shaping the glass.
- the object of the present invention is to develop a bottle of simple manufacture, which can be produced at relatively low temperatures compared to the temperatures necessary for the manufacture of glass bottles, which are light and reusable and which allow a wide variety of shapes depending on the applications.
- the subject of the invention is a bottle formed of a wall comprising a base, a body and a neck, bottle characterized in that the wall made of composite material is composed of a knit of natural fibers combined with thermoplastic material, the wall being shaped and stabilized by injection, molding or by thermocompression, the knit being a sleeve closed by a bottom and having a variable section rising towards the neck, depending on the shape of the bottle.
- the bottle according to the invention has the advantage of being very simple to manufacture whatever the particular shape of the bottle or of the different parts of the bottle, a more or less symmetrical shape, a flat bottom or a bottom with a stitching, a body with a round, oval, polygonal section or a combination of different section shapes along its height, a more or less accentuated shoulder, an elongated or very short neck in the case of jars or bottles.
- the bottle can also have a smooth ring like that of traditional bottles closed with a cork, synthetic material or glass or even a threaded ring to receive a screw cap or even a bead-shaped ring to clip a lid or a capsule as, for example, on soft drink capsules.
- Knitting has the advantage of passing on from stitch to stitch the stresses produced by local deformations so that the whole is balanced and the stitches are evenly distributed.
- the bottle has the advantage of being made with a knit constituting the wall of the whole of the bottle going from the bottom of the bottle, whether it is flat or with stitching, to the orifice of the neck.
- This bottle is simple and economical to produce since the manufacturing temperature is in a way the melting temperature of the thermoplastic material for the impregnation of the knit and the final shaping and stabilization of this shape by molding, compression, gluing or thermocompression.
- the bottle as produced can also receive an interior coating if this is necessary for certain types of liquids.
- the bottle thus produced is also recyclable or compostable as industrial compost.
- the knit comprises at least one of the following elements: a flat bottom part and, a stitching part, a body part, a shoulder part, a collar part and a ring part for a smooth ring or for a screw ring.
- These elements can have very variable dimensions and shapes depending on the nature of the bottle, that is to say whether it is a bottle with a relatively narrow or wide neck, ranging from the shape of a bottle traditional to fancy bottles, jars or flasks.
- the ring is also suitable for receiving the various closure means including a mechanical closure for bottles receiving a gaseous liquid.
- a subject of the invention is also a method for producing such a bottle, the method being characterized in that, in an initial step, a yarn of natural fibers is fed, a knit in the form of a sleeve is knitted with this yarn. having a bottom and the shape of which corresponds to that of the bottle to be produced, the thermoplastic material is combined with the knit and the knit combined with the thermoplastic material is shaped by a thermoforming step.
- the knit is combined with the thermoplastic material by means of a polyvinyl acetate (PVA), polyvinyl alcohol (PVOH) type glue or a biosourced glue based on casein, starch, chitin, chitosan, alginate, lignin, or wax.
- the assembly of the knit and the shell is done by means of a film of the same nature as the shell and heat-shrinkable.
- the advantage of these two variants is that at the end of the bottle's life, the linen knit is separable from the thermoplastic shell, which facilitates the recycling of the two parts of the bottle.
- This process is very simple to implement and thanks to the knit which constitutes the base of the wall of the bottle, all shapes can be envisaged very simply by the shape given to the knit which imitates more or less closely the final shape of the bottle, the elasticity of the knitting making it possible to adapt the knitting to the final shape without weakening this or that part of the surface of the wall, the knitting adapting by elasticity, regularly to the surface thus covered.
- thermoplastic material is combined with the yarn of natural fibers by extrusion, by injection of plastic material.
- the subject of the invention is a process consisting in combining the yarns of natural fibers with the thermoplastic material by supplying the knitting step with yarn of natural fibers and thermoplastic filaments.
- thermoplastic in the natural fibers to form the composite wall is extremely simple since it consists in starting, as a starting element, from natural fibers and thermoplastic fibers which are directly knitted with each other to join them and then allow by thermocompression, the fusion and the infiltration of the material. thermoplastic in the natural fibers to form the composite wall.
- the invention also relates to a method according to which the yarn of natural fibers is combined with the thermoplastic material by combining the yarn of natural fibers with thermoplastic filaments to supply the knitting step with a yarn thus combined.
- the natural fibers are combined in the form of yarns, ribbons, rovings with the thermoplastic material - presented in the same forms as the natural fibers by a co-mixing step to obtain a co- mixed or, the yarn of natural fibers is combined with the thermoplastic filaments by a wrapping step to obtain a wrapped yarn.
- FIG. 1 front view of a bottle of traditional wine bottle shape, according to the invention
- FIG. 2 front view of the bottle of Figure 1, cut in half along a median plane
- Figure 1 is a side view of an example of bottle 1 according to the invention for a traditional wine bottle shape in two variants. It is made of a composite material comprising a knit T of natural fibers (A) combined with a thermoplastic material (B).
- Bottle 1 consists of an 13 body with an 11 12-stitched bottom or an 11 flat bottom, an 14 shoulder and a neck. 15 ending in a ring 16.
- the body has patterns 17 in the form of distinctive or decorative elements such as an acronym, mark, engraving or other distinctive signs.
- the distinctive elements include, for example, a brand, or distinctive element of a product category. These elements are particular shapes given to the composite wall of the bottle and, where appropriate, elements integrated into the wall.
- the pattern 17 is, by way of example, formed in the composite mass and may or may not come in relief from the outer surface of the bottle or else the pattern 17 creates an effect by transparency or elements of color forming a distinctive effect in the mass.
- Figure 2 shows, in its left part 2A, a half-section through a plane passing through the median axis XX and in its right part 2B an uncut view of the bottle 1.
- the two examples of bottle highlighted in the half-view in section correspond to two knits T1, T'1 shown separately in parts 2C, 2D of this figure 2.
- the two separate parts 2C, 2D highlight the shape of the composite wall of the bottle consisting of a knit T1, T'1.
- the knits will be impregnated with a thermoplastic material highlighting the shape of the composite wall of the bottle consisting of a knit T1, T'1 having at least substantially the shape of the bottle. They will be impregnated with a thermoplastic material to create a stable wall, sealed, in a single part between the bottom 11 and the opening of the neck beyond the ring 16.
- Part 2C shows the shape of the knit T1 consisting of a sleeve open at one end and closed at its other end by the bottom T1 1 with a stitch T1 2.
- the knit T1 has, going up towards the collar, the shape of body T13 then that of the shoulder T14 followed by that of the neck T1 5 and of the ring T16 with the extra thickness.
- this part 2C representing the cut of the knit T1 the surface of the knit is irregular since it is not yet combined with the thermoplastic material and its shape is not stabilized by thermocompression.
- the knitting variant TT for a bottle with a flat bottom consists of the flat bottom part Tl 1, those of the body T13, the shoulder T14, the neck T15 and the ring T16 with.
- the knits Tl, TT have a pattern part Tl 7.
- the T (Tl, TT) knit has a flat bottom Tl 1 for a bottle with a flat bottom or a shape Tl 2 for a bottle with a sting. This shape consists of a domed extension beyond the YY plane of the bottom.
- the knit T (Tl, TT) has a variable section with respect to the XX axis. In the deployed state, the shape T 12 corresponds substantially to the symmetrical shape of the puncture 12 with respect to the plane YY of the bottom perpendicular to the axis XX of the bottle.
- the section of the knit T corresponds to that of the body Tl 3 then it decreases according to the shape of the shoulder Tl 4 to the neck Tl 5 and ends with the ring Tl 6 with an extra thickness of the knit at the level of the ring while, moreover, the thickness of the wall and therefore that of the knit, is constant.
- these extra thicknesses can be those obtained by molding and with a knit modified according to the reliefs by Tl 7 patterns.
- the knit T (Tl, TT) is knitted to have a regular density, equal everywhere on the surface of the wall of the bottle 1 , except where the thickness is changed for the ring or for patterns.
- the thickness of the wall and therefore that of the knit T depends on the nature of the liquid to be received depending on whether the liquid is with or without pressure.
- the knit T forming the wall of the bottle is made by combining natural fiber yarns (A) together before or after knitting with plastic material (B) combining with natural fiber threads, by thermocompression to obtain and stabilize the final shape of the bottle 1.
- bottle encompasses all the particular shapes of bottles, in particular bottles, jars of food liquids other than those traditionally packaged in bottles (wine, alcohol) or food or cosmetic gels, but also prismatic shapes used for fruit juices or similar liquids.
- the shape of the knit T will be adapted / copied from that of the bottle to be made, taking into account the elasticity of the knit T for its placement in a mould.
- FIG. 3 is the diagram of a first example P1 of a method for manufacturing a bottle 1 according to the invention.
- a knitting T is knitted having overall the shape of the bottle to be produced, for example the shape of the bottle of the figures 1, 2.
- the knit T then receives plastic material (step E3), by extrusion (step E31) or by injection (step E32) or by rotational molding (E33).
- These operations consist of pressing the natural fiber yarn knit (A) against the wall of the mold to take the shape of the bottle by soaking up the thermoplastic material extruded into the mold or rotomolded in the mold already lined with the knit T or in the state of an injected plastic preform which is expanded in the mold already lined with the T knit.
- thermoplastic shell is produced beforehand by injection, extrusion or rotational molding and a knit is placed on the thermoplastic shell.
- a thin thermoplastic, heat-shrinkable film is placed between the thermoplastic shell and the linen knit or above the thermoplastic shell and the knit and the film shrinks on contact with hot steam.
- thermocompression step E4 ensures the finishing and stabilization of the shape of bottle 1.
- thermoplastic shell is covered with a heat-shrinkable film and knitted yarn of natural fibers, the assembly and consolidation being done by means of hot steam which causes the film to shrink.
- Figure 4 shows a second process which combines natural fiber yarns (A) with thermoplastic filaments (B) by knitting. The knit T obtained is then shaped and stabilized by thermocompression to obtain the bottle 1.
- This process P2 consists of using natural fiber yarns (A) and thermoplastic filament yarns (B) or simple thermoplastic filaments (B) to produce the knit T by directly supplying the knitting step (F3) with these two yarn types (A) and yarns or filaments (B).
- the feed step F1 is followed by a step of combining F2 by co-mixing F21 of natural fiber yarns (A) and yarns or filaments of thermoplastic material (B) to obtain a commingled yarn (C) which feeds the knitting step F3.
- This is followed by the thermocompression stage F4.
- the step of combining F2 consists in wrapping F22 the thermoplastic filaments (B) on the yarn of natural fibers (A) to obtain a wrapped yarn (D) which arrives at the knitting step F3 followed by the thermocompression step F4.
- this intermediate step consists of combining the two types of yarn (A), yarn-filaments (B) to supply the knitting step with the yarn (C) resulting from this prior combination of the two yarns A, B.
- the process consists in knitting E2 natural fiber yarns (A) then adding to the knitting (T) the thermoplastic material (B) for shaping by thermocompression, by molding, by gluing and heat shrinking,
- the method can also consist in joining the yarns of natural fibers A and the yarns to the thermoplastic filaments B by knitting and then shaping and stabilizing the knit T combined with the plastic material by thermocompression.
- This method may also include an intermediate step of combination F2 consisting of: - producing co-mingled yarns (step F21) by combining natural fibers A with thermoplastic material B, the co-mingled yarns C then being knitted or ,
- step F22 - producing covered yarns by covering thermoplastic filaments B on natural fiber yarns A for obtain a covered yarn (D) which will then be knitted (step F3) then thermocompressed (step F4).
- Figure 5 shows the summary of the manufacturing process of a bottle as follows:
- the shape is stabilized by thermal action, either by thermocompression with steam or by thermocompression obtained by shrinking the film.
- a knit T is made which is placed in a mold to impregnate it with glue and obtain the blank which is stabilized by thermocompression to obtain the bottle or
- a knit is made which is placed in a mold assembled with a shell and the knit is impregnated with glue to stabilize the shape by thermocompression.
- a knit T is produced which is installed in a mold to assemble it to a shell C with the interposition of a heat-shrinkable film or coating of the knit with a heat-shrinkable film, then the thermocompression is carried out by heat-shrinking the film to obtain the bottle.
- a yarn is produced either by commingling the two yarns or by coverings. This yarn obtained is then knitted to be installed in a mold with shaping of the knit by inflation and then stabilization by thermocompression to obtain the product.
