Definitions

• the subject of the present invention is a bottle, in particular for beverages, in particular for alcoholic beverages or cosmetic products or perfumes comprising, on the one hand, a rigid outer shell ensuring the mechanical strength of the bottle, comprising a shell body extending by a neck as well as a lower cover and having a uniform appearance over the entire shell body and the neck covering at least 90% of their surface, on the other by an internal container intended to come into contact with the beverage or cosmetic product.
• a bottle or flask covering shell is known according to the document FR 2 549 009 .
• This shell makes it possible to decorate the bottle without having to decorate it directly in order to avoid, for example, annealing of the bottle, which would be done at high temperature.
• This shell consists of a body having the shape of the body of the bottle with a neck. If the bottom is necessary, it is added and welded to the body of the hull. To enable the bottle to be inserted into the shell and pass the neck, the neck of the shell is split over a certain length on two sides of the shell. The two slots are supposed to close elastically after the passage of the neck. It is also planned to hide these two slots once the bottle is in place, to improve the aesthetics of the shell.
• the combination of the shell to the bottle is done for a bottle, generally full because the empty bottle, dressed in the shell could not circulate in a casing line if only because of its size.
• This assembly uniting a shell to a bottle has many disadvantages such as the complexity of manufacture, the difficulty of assembling the bottle to the shell and the time necessary especially since this assembly is complex to achieve by a machine and the size of this combination relative to a bottle allows this shell to be applied only to bottles already filled.
• Another drawback is the weight of the assembly, which is that of the bottle plus that of the shell.
• the object of the present invention is to produce a bottle having the advantages of the decorative possibilities of a bottle with a covering shell without having the disadvantages of manufacture and use of the bottle + shell combination and in particular to reduce the weight of the bottle.
• This bottle may have any conventional or other shape without departing from the scope of the invention.
• Such a bottle may, for example, contain beer, still or sparkling wines, or spirit drinks with a high alcohol content of up to 60% such as whisky, cognac, Armagnac, rum, gin, vodka, juniper,...
• Such beverages are traditionally packaged in glass bottles, the aesthetics of which is often questionable, which have the disadvantage of being heavy and mechanically weak and the production of which also requires a very large amount of energy with the corollary of a very unfavorable carbon footprint.
• the rigid shell comprises a shell body extending by a neck provided with a neck as well as a lower cover and is equipped with a cap made of a rigid material fitted onto the neck, fixed thereto. and comprising an external annular part as well as an internal annular part threaded inside the neck.
• the container intended to come into contact with the drink is fixed to the internal annular part of this cap.
• the shell is made of a cylindrical braid of vegetable fibers whose burning temperature is greater than 140°C, having a uniform appearance over the entire body of the shell and the neck and covering at least 90% of their surface.
• This cylindrical braid which is preferably obtained by braiding a fiber on a mandrel, is inserted into an impregnation matrix made of a thermoplastic resin whose melting point is less than or equal to 190°C.
• the container intended to come into contact with the drink is a polyethylene terephthalate (PET) container of specific shape fixed to the lower part of the internal annular part of the cap.
• PET polyethylene terephthalate
• the bottle can, by way of example, be obtained by an injection blow molding process from three elements previously manufactured by injection, namely a cap, a lower lid and a matrix impregnation having the shape of the bottle, as well as a cylindrical braid of plant fibers also having the shape of the bottle and a commercial PET container.
• the cylindrical braid of plant fibers is positioned on an inflatable bladder, in particular made of silicone, and the impregnation matrix is fitted onto the outer face of this braid, then the assembly thus constituted is inserted in a mold making it possible to obtain the shell body.
• the mold thus equipped is then heated and the inflatable bladder is pressurized so that the thermoplastic resin constituting the matrix impregnates the braid with plant fibres.
• the cap After cooling and demolding of the shell body, the cap is fixed on the neck thereof, the PET container is inserted at its internal part and fixed to the cap, then the manufacture of the shell body is completed by fixing the lower cover .
• the container intended to come into contact with the drink is a soft and flexible bag, in particular made of polyethylene (PE), fixed to the lower part of the internal annular part of the cap during the manufacture of the latter and inflated in particular with compressed air after manufacture of the shell body, fixing of the cap on the latter and preferably fixing of the lower cover.
• PE polyethylene
• the soft and flexible bag can have a monolayer or multilayer structure.
• the shell body can also be manufactured by an injection blow molding process of the aforementioned type.
• the constituent thermoplastic resin of the impregnation matrix is chosen from the following resins: PE, polypropylene (PP), PET and polylactic acid (PLA).
• thermoplastic resin it is essential to choose this thermoplastic resin so that it has a melting temperature lower than the burning temperature of the plant fibers constituting the cylindrical braid.
• polypropylene is particularly advantageous because of its inexpensive nature and its ease of forming, but has, as a general rule, the disadvantage of not being biodegradable and of not being able to be manufactured without synthetic products. , exclusively from biomass.
• thermoplastic resin constitutes less than 10% of the weight of the shell.
• Polylactic acids which are more expensive than polypropylene, have the advantage of being biodegradable under certain conditions.
• bottles in accordance with the invention whose impregnation matrix consists of PLA can be degraded by grinding followed by a stay in an industrial fermenter or a composter.
• the shell of the bottle has a diameter varying between about 30 mm and about 90 mm, and the braiding angle of the fiber constituting the cylindrical braid varies between 25° and 65° along this shell so as to obtain a uniform appearance over the entire surface of the shell body and the neck.
• the braiding angle of the fiber depends on the number of filaments and the final diameter to be obtained and that the variations in the diameter of the braid and the orientation of the fibers are a function of the braiding speed, therefore of chuck feed rate.
• the cylindrical braid of plant fibers is a braid of hemp fibers, bamboo fibers, rice fibers, or flax fibers.
• Such a braid can advantageously consist of a braid of flax fibers having about 0.3 mm in diameter and comprising 90 to 100 filaments, in particular 96 filaments each containing 5 fibers.
• a braid of this type has a specific weight of less than 1400 kg/m 3 and in the case of a bottle of conventional capacity, a weight of the order of 35 grams and is therefore particularly light.
