  • the present invention relates to the field of so-called secondary packaging, in particular secondary packaging for a bottle of cosmetic, toiletry or perfume product.
  • cosmetic product is understood to mean in particular all products for making up the skin, including the lips, and all compositions intended for bodily application, including so-called care products such as moisturizing creams. Toiletries include shower gels, bath products and body lotions. Perfumes designate in particular all perfuming or fragrant compositions intended for bodily application.
  • a secondary packaging corresponds to a packaging formed around the so-called primary packaging, the primary packaging being that which is in direct contact with the packaged product.
  • Secondary packaging is generally used to group products together to form batches and/or transport them to their place of distribution, but in the field of cosmetics and in the field of perfumery, secondary packaging is primarily used to aesthetic and protective functions, each individual product being packed in one or more secondary packaging.
  • the secondary packaging of such a bottle thus generally comprises a case, optionally a wedge, and a sheath.
  • the case is a cardboard element, made of plastic, or of another suitable material (leather, wood, etc.), forming a box or a box for receiving the bottle.

  • the wedge is a piece of cardboard, plastic, foam, etc., which is shaped to prevent movement of the bottle in the case.
  • the wedge can be configured to match the shape of the bottle or simply to compensate for a clearance present in the case around the bottle.
  • the sheath is the outer packaging, in paper or cardboard, which surrounds the case.
  • a solution comprising three secondary packaging elements is complex. It requires the supply and storage of various elements. For the manufacture of each element, bending and cutting are necessary. The design of the secondary packaging is thus complex.
  • the packaging shapeing of the packaging, placement of the bottle in the packaging, etc.
  • several manipulations are necessary and can be complex to automate.
  • the production costs associated with the secondary packaging are thus high in the field of bottling, in particular the bottling of cosmetics, toiletries, and perfumes.
  • plastic materials and more generally of heterogeneous materials for the secondary packaging of cosmetic or perfume products makes the recycling of the packaging complex or impossible.
  • the invention thus aims to propose a secondary packaging for a bottle solving all or part of the aforementioned problems. It thus aims in particular to propose a packaging for a bottle which is aesthetic and distinctive, particularly suitable for the field of perfumery and cosmetic products, and which can be easily recycled or biodegraded.
  • the packaging proposed in the invention aims to obtain these functions while offering high-level protection, for the bottle in all its components: the glassware of the reservoir and/or of the bottle cap, its label (or other form of marking ), etc.
  • the invention relates to a packaging shell for a bottle of perfume, cosmetic or toiletry product, said shell being able to assume a closed position in which it forms a receiving volume adapted to envelop a bottle and an open position allowing the placing the bottle in the shell or removing the bottle from the shell, said shell comprising two half-shells each forming a concavity and essentially formed of a material based on molded natural plant fibres.

  • the process used to form the shell essentially implements a pulp of fibrous plant(s) containing natural plant fibers and water, in order to produce a hot molding of this pulp.
  • the transport of packaged products is optimized by light packaging, containing little material, and compact (which allows more bottles to be transported in the same volume). This allows a reduction of the "carbon footprint" due to the transport of the packaged bottles.
  • the shell may include a hinge which connects the two half-shells.

Description

La présente invention concerne le domaine des emballages dits secondaires, en particulier des emballages secondaires pour flacon de produit cosmétique, de toilette, ou de parfum.The present invention relates to the field of so-called secondary packaging, in particular secondary packaging for a bottle of cosmetic, toiletry or perfume product.

Par produit cosmétique, on entend notamment tous les produits pour le maquillage de la peau, y compris les lèvres, et toutes les compositions destinées à une application corporelle, y compris les produits dits de soin tels que les crèmes hydratantes. Les produits de toilette comprennent les gels douche, produits pour le bain, ainsi que les laits corporels. Les parfums désignent en particulier toutes les compositions parfumantes ou odorantes destinées à une application corporelle.The term “cosmetic product” is understood to mean in particular all products for making up the skin, including the lips, and all compositions intended for bodily application, including so-called care products such as moisturizing creams. Toiletries include shower gels, bath products and body lotions. Perfumes designate in particular all perfuming or fragrant compositions intended for bodily application.

Un emballage secondaire correspond à un emballage formé autour de l'emballage dit primaire, l'emballage primaire étant celui qui est au contact direct du produit emballé.A secondary packaging corresponds to a packaging formed around the so-called primary packaging, the primary packaging being that which is in direct contact with the packaged product.

L'emballage secondaire sert généralement à grouper les produits pour former des lots et/ou les acheminer à leur lieu de distribution, mais, dans le domaine des produits cosmétiques et dans le domaine de la parfumerie, l'emballage secondaire sert en premier lieu à des fonctions esthétiques et protectrices, chaque produit individuel étant emballé dans un ou plusieurs emballages secondaires.Secondary packaging is generally used to group products together to form batches and/or transport them to their place of distribution, but in the field of cosmetics and in the field of perfumery, secondary packaging is primarily used to aesthetic and protective functions, each individual product being packed in one or more secondary packaging.

Généralement, plusieurs éléments sont employés pour former l'emballage secondaire d'un flacon de produit (parfum, produit cosmétique ou de toilette), le flacon formant l'emballage primaire dudit produit.Generally, several elements are used to form the secondary packaging of a bottle of product (perfume, cosmetic or toiletry product), the bottle forming the primary packaging of said product.

L'emballage secondaire d'un tel flacon comporte ainsi généralement un étui, optionnellement une cale, et un fourreau.The secondary packaging of such a bottle thus generally comprises a case, optionally a wedge, and a sheath.

L'étui est un élément cartonné, en plastique, ou d'un autre matériau approprié (cuir, bois, etc.), formant une boîte ou un boîtier de réception du flacon. L'étui porte généralement les mentions légales et commerciales. La cale est un élément cartonné, en plastique, en mousse, etc., qui est conformé pour éviter les mouvements du flacon dans l'étui. La cale peut être configurée pour épouser la forme du flacon ou simplement pour compenser un jeu présent dans l'étui autour du flacon.The case is a cardboard element, made of plastic, or of another suitable material (leather, wood, etc.), forming a box or a box for receiving the bottle. The case generally bears the legal and commercial notices. The wedge is a piece of cardboard, plastic, foam, etc., which is shaped to prevent movement of the bottle in the case. The wedge can be configured to match the shape of the bottle or simply to compensate for a clearance present in the case around the bottle.

Le fourreau est le conditionnement extérieur, en papier ou en carton, qui entoure l'étui. Une telle solution comportant trois éléments d'emballage secondaire est complexe. Elle nécessite l'approvisionnement et le stockage des divers éléments. Pour la fabrication de chaque élément, des pliages et des découpes sont nécessaires. La conception de l'emballage secondaire est ainsi complexe. En outre, lors de la mise en œuvre de l'emballage (mise en forme de l'emballage, mise en place du flacon dans l'emballage, etc.), plusieurs manipulations sont nécessaires et peuvent être complexes à automatiser. Les coûts de production associés à l'emballage secondaire sont ainsi importants dans le domaine du flaconnage, en particulier du flaconnage des produits cosmétiques, de toilette, et des parfums.The sheath is the outer packaging, in paper or cardboard, which surrounds the case. Such a solution comprising three secondary packaging elements is complex. It requires the supply and storage of various elements. For the manufacture of each element, bending and cutting are necessary. The design of the secondary packaging is thus complex. In addition, during the implementation of the packaging (shaping of the packaging, placement of the bottle in the packaging, etc.), several manipulations are necessary and can be complex to automate. The production costs associated with the secondary packaging are thus high in the field of bottling, in particular the bottling of cosmetics, toiletries, and perfumes.

En outre, l'emploi de matériaux plastiques et plus généralement de matériaux hétérogènes pour l'emballage secondaire des produits cosmétiques ou de parfum rend le recyclage des emballages complexe ou impossible.In addition, the use of plastic materials and more generally of heterogeneous materials for the secondary packaging of cosmetic or perfume products makes the recycling of the packaging complex or impossible.

L'invention vise ainsi à proposer un emballage secondaire pour flacon résolvant tout ou partie des problèmes précités. Elle vise ainsi en particulier à proposer un emballage pour flacon qui soit esthétique et distinctif, particulièrement adapté au domaine de la parfumerie et des produits cosmétiques, et pouvant être facilement recyclé ou biodégradé. L'emballage proposé dans l'invention vise à obtenir ces fonctions tout en proposant une protection de haut niveau, pour le flacon dans toutes ses composantes : la verrerie du réservoir et/ou du bouchon du flacon, son étiquette (ou autre forme de marquage), etc.The invention thus aims to propose a secondary packaging for a bottle solving all or part of the aforementioned problems. It thus aims in particular to propose a packaging for a bottle which is aesthetic and distinctive, particularly suitable for the field of perfumery and cosmetic products, and which can be easily recycled or biodegraded. The packaging proposed in the invention aims to obtain these functions while offering high-level protection, for the bottle in all its components: the glassware of the reservoir and/or of the bottle cap, its label (or other form of marking ), etc.

Ainsi, l'invention porte sur une coque d'emballage pour flacon de parfum, de produit cosmétique ou de toilette, ladite coque pouvant prendre une position fermée dans laquelle elle forme un volume de réception adapté à envelopper un flacon et une position ouverte permettant la mise en place du flacon dans la coque ou le retrait du flacon de la coque, ladite coque comportant deux demi-coques formant chacune une concavité et essentiellement formées d'un matériau à base de fibres naturelles végétales moulé. Chaque demi-coque comporte un bord périphérique qui est jointif, lorsque la coque est en position fermée, d'un bord périphérique de l'autre demi-coque de sorte que le volume de réception est un volume clos et en ce que la coque présente au moins un élément de maintien en saillie dans le volume de réception. Les éléments de maintien sont moulés avec la coque.Thus, the invention relates to a packaging shell for a bottle of perfume, cosmetic or toiletry product, said shell being able to assume a closed position in which it forms a receiving volume adapted to envelop a bottle and an open position allowing the placing the bottle in the shell or removing the bottle from the shell, said shell comprising two half-shells each forming a concavity and essentially formed of a material based on molded natural plant fibres. Each half-shell has a peripheral edge which is contiguous, when the shell is in the closed position, with a peripheral edge of the other half-shell so that the receiving volume is a closed volume and in that the shell has at least one retaining element projecting into the receiving volume. The support elements are molded with the shell.

La formation d'une coque en fibres naturelles par moulage présente de multiples avantages. Le procédé de moulage d'un matériau à base de fibres naturelles permet en une seule opération de réaliser la coque, ou une partie de la coque. Surtout, ce procédé permet l'obtention de formes complexes et esthétiques. Il est en particulier possible de former une coque épousant la forme du flacon qu'elle est destinée à contenir, ce qui offre à la coque une esthétique valorisante, notamment en ce que la coque peut reprendre, sur tout ou partie de sa surface, la forme du flacon. Une telle coque est en ainsi particulièrement esthétique, formant une sorte de peau autour du flacon. La coque peut ainsi reprendre la forme générale du flacon, rendant le produit immédiatement identifiable pour le consommateur, notamment pour certains parfums dont la forme du flacon est extrêmement connue et distinctive. En outre, en reprenant la forme du flacon au plus proche, l'emballage suggère la forme et le volume du flacon, et respecte ainsi les réglementations en matière de ratio entre l'emballage primaire et l'emballage secondaire qui visent à éviter toute tromperie du consommateur sur les dimensions et la contenance réelle du produit présent dans le paquet. De manière plus générale, le volume de l'emballage est optimisé, et l'utilisateur a ainsi une bonne idée du volume du flacon présent dans l'emballage.Forming a natural fiber shell by molding has multiple advantages. The method of molding a material based on natural fibers makes it possible in a single operation to produce the shell, or part of the shell. Above all, this process makes it possible to obtain complex and aesthetic shapes. It is in particular possible to form a shell matching the shape of the bottle that it is intended to contain, which gives the shell an aesthetic value, in particular in that the shell can take up, on all or part of its surface, the shape of the bottle. Such a shell is thus particularly aesthetic, forming a kind of skin around the bottle. The shell can thus take on the general shape of the bottle, making the product immediately identifiable for the consumer, in particular for certain perfumes for which the shape of the bottle is extremely well known and distinctive. In addition, by taking the shape of the bottle as closely as possible, the packaging suggests the shape and volume of the bottle, and thus respects the regulations in terms of the ratio between the primary packaging and the secondary packaging which aim to avoid any deception. of the consumer on the dimensions and the actual capacity of the product present in the package. More generally, the volume of the packaging is optimized, and the user thus has a good idea of the volume of the bottle present in the packaging.

La combinaison de la forme générale de la coque, du matériau employé, et de la présence d'élément de maintien en saillie dans la coque garantit une bonne protection du flacon, notamment contre les chocs.The combination of the general shape of the shell, the material used, and the presence of a retaining element projecting into the shell guarantees good protection of the bottle, in particular against shocks.

Le matériau essentiellement (c'est-à-dire au moins très majoritairement) employé pour réaliser la coque est recyclable et/ou biodégradable. Le procédé employé pour former la coque met en effet essentiellement en œuvre une pulpe de plante(s) fibreuse(s) contentant des fibres naturelles végétales et de l'eau, afin de réaliser un moulage à chaud de cette pulpe.The material essentially (that is to say at least very predominantly) used to make the shell is recyclable and/or biodegradable. The process used to form the shell essentially implements a pulp of fibrous plant(s) containing natural plant fibers and water, in order to produce a hot molding of this pulp.

Enfin, le transport des produits conditionnés est optimisé par un emballage léger, comportant peu de matière, et compact (ce qui permet de transporter plus de flacons dans un même volume). Cela permet une réduction de l'« empreinte carbone » due au transport des flacons conditionnés.Finally, the transport of packaged products is optimized by light packaging, containing little material, and compact (which allows more bottles to be transported in the same volume). This allows a reduction of the "carbon footprint" due to the transport of the packaged bottles.

La coque peut comporter une charnière qui relie les deux demi-coques.The shell may include a hinge which connects the two half-shells.

Différentes constitutions de la coque sont ainsi envisageables, sur le fondement d'un ou plusieurs éléments moulés d'un matériau à base de fibres naturelles végétales.Different constitutions of the hull are thus possible, on the basis of one or more molded elements of a material based on natural plant fibers.

La formation en deux demi-coques articulées forme un écrin valorisant pour le flacon que la coque est destinée à contenir.The formation in two articulated half-shells forms a valuable setting for the bottle that the shell is intended to contain.

La coque peut comporter une paroi extérieure et une paroi intérieure, la paroi intérieure définissant le volume de réception en position fermée de la coque. La paroi extérieure de la coque et la paroi intérieure de la coque peuvent être formées de deux couches distinctes dudit matériau à base de fibres naturelles, à savoir une couche interne formant la paroi intérieure et une couche externe formant la paroi extérieure, la couche interne comportant les moyens de maintien.The shell may comprise an outer wall and an inner wall, the inner wall defining the reception volume in the closed position of the shell. The outer wall of the hull and the inner wall of the hull may be formed of two distinct layers of said material based on natural fibers, namely an inner layer forming the inner wall and an outer layer forming the outer wall, the inner layer comprising the means of maintenance.

En formant chaque demi coque de deux couches distinctes, il est ainsi possible de ne mouler les moyens de maintien que sur la couche intérieure de la coque. L'aspect esthétique, notamment la forme, de la couche extérieure est préservé. En outre, une poche creuse peut être formée entre les deux couches au niveau des éléments de maintien, ce qui améliore leur déformabilité. Cela permet aux moyens de maintien de s'adapter plus aisément aux tolérances de fabrication des flacons destinés à être placés dans la coque, et cela améliore leur capacité à absorber les chocs et autres contraintes subies par la coque.By forming each half-shell of two separate layers, it is thus possible to mold the holding means only on the inner layer of the shell. Appearance aesthetics, in particular the shape, of the outer layer is preserved. In addition, a hollow pocket can be formed between the two layers at the level of the holding elements, which improves their deformability. This allows the holding means to adapt more easily to the manufacturing tolerances of the bottles intended to be placed in the shell, and this improves their ability to absorb shocks and other stresses to which the shell is subjected.

Les fibres naturelles utilisées peuvent comporter des fibres de canne à sucre, de bambou, de bois, de coton, de lin, de chanvre, de sisal, de jute, de kénaf ou de coco. L'emploi de fibres de bagasse (issue de canne à sucre) ou de bambou est particulièrement préféré. L'emploi d'une ou plusieurs des fibres végétales citées permet la formation d'une coque du type en « papier » moulé ayant diverses propriétés mécaniques et esthétiques.The natural fibers used may include sugar cane, bamboo, wood, cotton, flax, hemp, sisal, jute, kenaf or coir fibers. The use of bagasse fibers (from sugar cane) or bamboo is particularly preferred. The use of one or more of the plant fibers mentioned allows the formation of a molded “paper” type shell having various mechanical and aesthetic properties.

La coque d'emballage peut présenter par exemple une épaisseur de paroi comprise entre 0,5 mm et 3 mm, préférentiellement entre 0.8 et 2 mm en tout point de ladite coque à l'exception des zones ou est formé un élément de maintien.The packaging shell may for example have a wall thickness of between 0.5 mm and 3 mm, preferably between 0.8 and 2 mm at any point of said shell with the exception of the zones where a holding element is formed.

Des essais ont permis de déterminer qu'une telle épaisseur permet une protection satisfaisante d'un flacon de verrerie, par exemple un flacon de parfum de taille classique (par exemple de 100 ml), en cas de chute d'une hauteur de 90cm sur une surface solide, ce qui correspond à une situation de chute courante pour un flacon de parfum ou de produit cosmétique (chute d'une table, d'un présentoir, d'un sac, etc.).Le volume de réception formé par la coque peut comporter une paroi avant, une paroi arrière, et des parois latérales reliant la paroi avant à la paroi arrière, et les éléments de maintien comportent : au moins un contrefort en saillie sur au moins l'une des parois latérales, et/ou au moins un plot en saillie sur au moins l'une des faces avant et arrière, et/ou au moins un bourrelet allongé ou définissant une forme fermée, sur au moins l'une des faces avant et arrière.Tests have made it possible to determine that such a thickness allows satisfactory protection of a glassware bottle, for example a perfume bottle of conventional size (for example 100 ml), in the event of a fall from a height of 90 cm on a solid surface, which corresponds to a common fall situation for a bottle of perfume or cosmetic product (falling from a table, a display, a bag, etc.). The receiving volume formed by the shell may comprise a front wall, a rear wall, and side walls connecting the front wall to the rear wall, and the retaining elements comprise: at least one buttress projecting from at least one of the side walls, and/or at least one projecting stud on at least one of the front and rear faces, and/or at least one elongated bead or defining a closed shape, on at least one of the front and rear faces.

Les éléments de maintien peuvent ainsi prendre des formes et des dimensions diverses, adaptés à leur fonction particulière.The holding elements can thus take various shapes and sizes, adapted to their particular function.

Les éléments de maintien situés sur les parois internes latérales de la coque peuvent ainsi avoir la forme de bloc ou de coins de maintien, afin de fournir une surface d'appui relativement importante au flacon contenu dans la coque.The holding elements located on the inner side walls of the shell can thus have the shape of a block or of holding wedges, in order to provide a relatively large bearing surface for the bottle contained in the shell.

Les éléments de maintien situés sur les faces avant et arrière peuvent avoir la forme de petits plots cylindriques ou hémisphériques, qui apportent un maintien ponctuel en des zones choisies du flacon contenu dans la coque, tout en étant esthétiques.The holding elements located on the front and rear faces may have the form of small cylindrical or hemispherical studs, which provide occasional holding in selected areas of the bottle contained in the shell, while being aesthetic.

Des bourrelets permettent de former un appui linéique vis-à-vis du flacon. Comme détaillé ci-après, les plots et/ou les bourrelets peuvent permettre de former un appui sur le flacon autour d'une zone de marquage de celui-ci, afin de préserver le marquage de toute dégradation par frottement, même de faible amplitude, sur la coque.Beads make it possible to form a linear support vis-à-vis the bottle. As detailed below, the studs and/or the beads can make it possible to form a support on the bottle around a marking zone of the latter, in order to preserve the marking from any degradation by friction, even of low amplitude, on the hull.

Le volume de réception peut présenter une forme complexe destinée à épouser la forme d'un flacon, au jeu près formé par les éléments de maintien, ladite forme complexe comportant :

  • un volume de réception de réservoir, ayant une première section transversale ayant une première surface ;
  • un volume de réception d'un col, ayant une deuxième section transversale ayant une surface inférieure à la première surface ;
  • un volume de réception d'un bouchon, ayant une troisième section transversale ayant une surface comprise entre la première surface et la deuxième surface.
The receiving volume may have a complex shape intended to match the shape of a bottle, except for the clearance formed by the holding elements, said complex shape comprising:
  • a reservoir receiving volume, having a first cross-section having a first surface;
  • a neck-receiving volume, having a second cross-section having a lower surface than the first surface;
  • a cap-receiving volume, having a third cross-section having an area between the first surface and the second surface.

La conformation de la coque au plus près du flacon qu'elle contient offre une bonne protection du flacon et une bonne esthétique de la coque, en ce qu'elle reprend parfaitement la forme générale du flacon qu'elle contient et bénéficie ainsi de son aspect distinctif.The conformation of the shell as close as possible to the bottle it contains offers good protection for the bottle and good aesthetics of the shell, in that it perfectly matches the general shape of the bottle it contains and thus benefits from its appearance. distinctive.

L'invention porte également sur un ensemble comportant une coque d'emballage pour flacon telle que définie ci-dessus et un flacon contenu dans ladite coque d'emballage.The invention also relates to an assembly comprising a packaging shell for a bottle as defined above and a bottle contained in said packaging shell.

Dans un tel ensemble, la coque peut épouser la forme extérieure du flacon qu'elle contient, de sorte qu'en tout point de ladite coque, un jeu maximum de 4 mm, de préférence au maximum de 2 mm, est présent entre une paroi extérieure du flacon et la paroi intérieure de la coque.In such an assembly, the shell can match the external shape of the bottle it contains, so that at any point of said shell, a maximum play of 4 mm, preferably a maximum of 2 mm, is present between a wall exterior of the bottle and the interior wall of the shell.

Par ailleurs, les éléments de maintien peuvent être configurés pour maintenir le flacon à distance des parois avant, arrière et latérales de la coque.Furthermore, the holding elements can be configured to hold the bottle away from the front, rear and side walls of the shell.

Lorsque le flacon comporte un marquage rapporté, les éléments de maintien peuvent être configurés de sorte que le marquage rapporté est maintenu à distance de la coque et que lesdits éléments de maintien ne sont pas au contact dudit marquage rapporté. La coque est ainsi configurée pour une protection optimale du flacon qu'elle contient. La coque peut envelopper en totalité ledit flacon, de sorte qu'aucune partie du flacon ne dépasse de ladite coque lorsque celle-ci est fermée. Une protection de l'ensemble du flacon est ainsi obtenue. En outre, en enveloppant le col et le bouchon du flacon, la coque lorsqu'elle est fermée participe à empêcher un retrait accidentel du bouchon.When the bottle has an added marking, the holding elements can be configured so that the added marking is kept at a distance from the shell and that said holding elements are not in contact with said added marking. The shell is thus configured for optimal protection of the bottle it contains. The shell can completely envelop said bottle, so that no part of the bottle protrudes from said shell when the latter is closed. Protection of the entire bottle is thus obtained. In addition, by wrapping the neck and the stopper of the bottle, the shell when it is closed helps to prevent accidental removal of the stopper.

Le flacon peut avantageusement être un flacon de verrerie.The bottle can advantageously be a glassware bottle.

Par sa constitution et son esthétique, la coque est particulièrement adaptée à la protection d'un flacon de verrerie, sensible aux chocs par nature. Par flacon de verrerie, on entend tout flacon en verre, de toute sorte, y compris en cristal.By its constitution and its aesthetics, the shell is particularly suitable for the protection of a bottle of glassware, sensitive to shocks by nature. By glassware bottle is meant any glass bottle, of any kind, including crystal.

D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci-après.Other features and advantages of the invention will appear further in the description below.

Le flacon 1 représenté à la figure 1 comporte un corps 2 qui forme un réservoir pour le parfum et un col 3. Le col 3 comporte une ouverture permettant l'introduction du parfum dans le réservoir du corps 2 et la sortie du parfum du réservoir du corps 2. Dans l'exemple ici représenté le col 3 comporte des moyens de distribution du parfum, à savoir une pompe et un bouton poussoir. Le col 3 est surmonté d'un bouchon 4 permettant l'obturation du col 3 et/ou de recouvrir les moyens de distribution.Bottle 1 shown in figure 1 comprises a body 2 which forms a reservoir for the perfume and a neck 3. The neck 3 comprises an opening allowing the introduction of the perfume into the reservoir of the body 2 and the outlet of the perfume from the reservoir of the body 2. In the example here shown the collar 3 comprises means for dispensing the perfume, namely a pump and a push button. The neck 3 is surmounted by a plug 4 allowing the closure of the neck 3 and/or covering the dispensing means.

À l'exception des moyens de distribution le flacon de la figure 1, et notamment son bouchon 4, est intégralement constitué de verre. Un tel flacon nécessite donc une protection mécanique, notamment contre les chocs, de l'ensemble de ses parties constitutives.With the exception of the means of distribution the vial of the figure 1 , and in particular its cap 4, is entirely made of glass. Such a bottle therefore requires mechanical protection, in particular against shocks, of all of its constituent parts.

Par ailleurs, un tel flacon à une forme générale complexe mais particulièrement esthétique et distinctive, qu'il conviendrait de mettre en valeur y compris lorsque le flacon est emballé.Moreover, such a bottle has a complex but particularly aesthetic and distinctive general shape, which should be highlighted, including when the bottle is packaged.

La figure 2 représente une coque 5 d'emballage conforme à un mode de réalisation de l'invention. Cette coque est représentée dans une position ouverte. Cette coque est configurée pour recevoir, protéger, et habiller le flacon 1 représenté à la figure 1.There figure 2 represents a packaging shell 5 in accordance with one embodiment of the invention. This shell is shown in an open position. This shell is configured to receive, protect, and dress the bottle 1 shown in figure 1 .

La position ouverte de la coque 5 représentée à la figure 2 correspond à une position dans laquelle le flacon 1 peut être mis en place dans la coque 5 ou extrait de la coque 5. La coque 5 comporte une première demi-coque 6 et une deuxième demi-coque 7. La première demi-coque 6 et la deuxième demi-coque 7 sont reliées entre elles par une charnière 8. La charnière 8 permet de faire passer la coque 5 de sa position ouverte à une position fermée dans laquelle elle forme un volume intérieur adapté à envelopper le flacon 1.The open position of the shell 5 shown in figure 2 corresponds to a position in which the bottle 1 can be placed in the shell 5 or extracted from the shell 5. The shell 5 comprises a first half-shell 6 and a second half-shell 7. The first half-shell 6 and the second half-shell 7 are interconnected by a hinge 8. The hinge 8 makes it possible to move the shell 5 from its open position to a closed position in which it forms an interior volume adapted to envelop the bottle 1.

La première demi-coque 6 et la deuxième demi-coque 7 ont chacune une forme concave adaptée à la réception du flacon 1.The first half-shell 6 and the second half-shell 7 each have a concave shape suitable for receiving the bottle 1.

Le flacon 1 de la figure 1 présentant deux plans de symétrie verticaux, la coque 5 est elle-même formée de deux demi-coques 6,7. La première demi-coque 6 et la deuxième demi-coque 7 peuvent être symétriques vis-à-vis de l'axe formé par la charnière 8.Bottle 1 of the figure 1 having two vertical planes of symmetry, the shell 5 is itself formed of two half-shells 6.7. The first half-shell 6 and the second half-shell 7 can be symmetrical with respect to the axis formed by the hinge 8.

La figure 3 représente quant à elle une partie de la coque 5 de la figure 2, à savoir la première demi-coque 6, selon une vue en perspective permettant d'apprécier certains détails de l'intérieur de la concavité de la demi-coque 6.There picture 3 represents a part of the shell 5 of the figure 2 , namely the first half-shell 6, according to a perspective view making it possible to appreciate certain details of the interior of the concavity of the half-shell 6.

La forme concave complexe de chaque demi-coque est obtenue par moulage d'un matériau à base de fibres naturelles végétales. En particulier, la coque 5 est essentiellement fabriquée en pulpe végétale moulée, le moulage à chaud de la pulpe permettant de donner au matériau une forme qui épouse parfaitement les contours du flacon à emballer.The complex concave shape of each half-shell is obtained by molding a material based on natural plant fibres. In particular, the shell 5 is essentially made of molded vegetable pulp, the hot molding of the pulp making it possible to give the material a shape which perfectly matches the contours of the bottle to be packaged.

La pulpe est avantageusement obtenue à partir de fibres de bagasse et/ou de fibres de bambou.The pulp is advantageously obtained from bagasse fibers and/or bamboo fibers.

D'autres fibres naturelles peuvent être employées selon l'aspect et les propriétés, notamment mécaniques souhaitées.Other natural fibers can be used depending on the desired appearance and properties, in particular mechanical properties.

Les fibres naturelles employées peuvent de manière générale être toutes les fibres employées dans l'industrie papetière, notamment, outre les fibres de canne à sucre (sous forme de bagasse) et de bambou, notamment de bois, de coton, de lin, de chanvre, de sisal, de jute, de kénaf ou de coco. Tout mélange comportant ces fibres est également envisageable.The natural fibers used can generally be all the fibers used in the paper industry, in particular, in addition to sugar cane fibers (in the form of bagasse) and bamboo, in particular wood, cotton, linen, hemp , sisal, jute, kenaf or coconut. Any mixture comprising these fibers can also be envisaged.

La première demi-coque 6 et la deuxième demi-coque 7 peuvent être formées d'un seul tenant, la charnière 8 étant alors formée par pliage entre les deux demi-coques. Alternativement, chaque demi-coque peut être formée d'une pièce distincte, et la charnière formée d'une pièce rapportée.The first half-shell 6 and the second half-shell 7 can be formed in one piece, the hinge 8 then being formed by bending between the two half-shells. Alternatively, each half-shell can be formed from a separate piece, and the hinge formed from an added piece.

Dans l'exemple de mode de réalisation de la figure 2, la charnière 8 est positionnée dans la zone de la coque 5 destinée à accueillir le fond du flacon 1. Cela rend la charnière 8 peu visible, améliore l'esthétique de l'ensemble, et offre une ouverture naturelle de la coque. Bien évidemment, une ouverture latérale de la coque par une charnière latérale pourrait être réalisée dans le cadre de l'invention, permettant une ouverture de la coque de manière analogue à l'ouverture d'un livre.In the exemplary embodiment of the figure 2 , the hinge 8 is positioned in the zone of the shell 5 intended to receive the bottom of the bottle 1. This makes the hinge 8 not very visible, improves the aesthetics of the whole, and offers a natural opening of the shell. Of course, a side opening of the shell by a side hinge could be made within the framework of the invention, allowing the shell to be opened in a manner analogous to the opening of a book.

La coque 5 a la particularité de présenter des éléments de maintien 16. Les éléments de maintien 16 sont des éléments qui font saillie à l'intérieur de la coque 5, c'est-à-dire à l'intérieur du volume de réception 10 que forme la coque 5 lorsqu'elle est en position fermée.The shell 5 has the particularity of having holding elements 16. The holding elements 16 are elements which protrude inside the shell 5, that is to say inside the reception volume 10 that the shell 5 forms when it is in the closed position.

Les éléments de maintien 16 peuvent avoir plusieurs fonctions. Tout d'abord, ils permettent de compenser les tolérances de fabrication du flacon qui est reçu dans la coque. Les tolérances de fabrication d'un flacon de verrerie peuvent en effet être importantes, relativement aux dimensions dudit flacon. Pour compenser ces tolérances de fabrication, les éléments de maintien sont adaptés à s'écraser légèrement lors de la mise en place d'un flacon dans la coque 5. Une fois en place, le flacon est ainsi parfaitement immobilisé dans la coque 5.The holding elements 16 can have several functions. First of all, they make it possible to compensate for the manufacturing tolerances of the bottle which is received in the shell. The manufacturing tolerances of a glassware bottle can indeed be significant, relative to the dimensions of said bottle. To compensate for these manufacturing tolerances, the retaining elements are adapted to crush slightly when a bottle is placed in the shell 5. Once in place, the bottle is thus perfectly immobilized in the shell 5.

Une autre fonction des moyens de maintien 16 peut être de maintenir un espace entre le flacon qui est mis en place dans la coque 5 et les parois de ladite coque 5.Another function of the holding means 16 may be to maintain a space between the bottle which is placed in the shell 5 and the walls of said shell 5.

Cela est notamment avantageux lorsque le flacon conditionné dans la coque comporte un marquage rapporté. Le marquage rapporté peut correspondre à une étiquette 15 qui porte une impression, un laquage, un vernis, ou une sérigraphie, etc., et qui est collée sur le flacon 1 (voir figure 1). Le marquage rapporté peut alternativement être un laquage, un vernis, une impression, ou une sérigraphie réalisée directement sur le flacon 1. Un tel marquage rapporté est susceptible d'être abîmé voire effacé par les frottements du flacon 1 dans la coque 5. Maintenir le marquage rapporté à distance de la paroi de la coque 5 évite une telle détérioration.This is particularly advantageous when the bottle packaged in the blister has an attached marking. The added marking may correspond to a label 15 which bears a print, a lacquer, a varnish, or a screen print, etc., and which is stuck on the bottle 1 (see figure 1 ). The added marking can alternatively be a lacquer, a varnish, a print, or a screen print made directly on the bottle 1. Such an added marking is likely to be damaged or even erased by the rubbing of the bottle 1 in the shell 5. Maintain the marking reported at a distance from the wall of the shell 5 avoids such deterioration.

Enfin, et de manière primordiale, les éléments de maintien 16 participent à la protection du flacon contenu dans la coque 5 contre les chocs, en particulier en cas de chute de la coque 5 contenant un flacon 1.Finally, and most importantly, the holding elements 16 contribute to the protection of the bottle contained in the shell 5 against shocks, in particular in the event of the shell 5 containing a bottle 1 falling.

Pour répondre aux différentes fonctions des moyens de maintien 16, plusieurs configurations, en termes de géométrie et de position dans la coque 5, de moyens de maintien peuvent être utilisées.To meet the different functions of the holding means 16, several configurations, in terms of geometry and position in the shell 5, of the holding means can be used.

Dans l'exemple de coque représentée à la figure 2 et à la figure 3, la coque comporte une paroi avant 18, une paroi arrière 19, et des parois latérales 20.In the hull example shown in figure 2 and at the picture 3 , the shell has a front wall 18, a rear wall 19, and side walls 20.

Les parois latérales 20 peuvent être équipées, en tant que moyens de maintien 16, de reliefs appelées contreforts 161. Les contreforts 161 sont de petites surépaisseurs parallélépipédiques ou « en coin », c'est à dire présentant une épaisseur variable régulièrement. Deux contreforts 161 peuvent être prévus sur chaque paroi latérale de chaque demi-coque, ou sur l'une seule des demi-coques, soit quatre ou huit contreforts au total dans une coque 5. Dans l'exemple représenté, huit contreforts 161 sont formés dans la coque 5.The side walls 20 can be equipped, as retaining means 16, with reliefs called buttresses 161. The buttresses 161 are small parallelepipedic or “corner” extra thicknesses, that is to say having a regularly variable thickness. Two buttresses 161 can be provided on each side wall of each half-shell, or on only one of the half-shells, i.e. four or eight buttresses in total in a shell 5. In the example shown, eight buttresses 161 are formed in the hull 5.

Comme cela est visible sur la figure 3, les contreforts 161 peuvent présenter un bord en pente 164 qui facilite l'introduction d'un flacon 1 dans la coque 5.As can be seen on the picture 3 , the buttresses 161 may have a sloping edge 164 which facilitates the introduction of a bottle 1 into the shell 5.

La paroi avant 18 et/ou la paroi arrière 19 peuvent être équipées de plots 162 ou d'un ou plusieurs bourrelets 163, en tant qu'élément de maintien. Dans l'exemple de mode de réalisation représenté, la paroi avant 18 comporte un bourrelet 163 et la paroi arrière 19 comporte quatre plots 162.The front wall 18 and/or the rear wall 19 can be equipped with studs 162 or with one or more beads 163, as a holding element. In the exemplary embodiment represented, the front wall 18 comprises a bead 163 and the rear wall 19 comprises four studs 162.

Les bourrelets et les plots peuvent être employés pour remplir des fonctions similaires. De manière générale, un plot 162 permet l'obtention d'une petite zone de contact avec le flacon 1, par exemple une zone quasi-ponctuelle de contact, tandis qu'un bourrelet 163 permet l'obtention d'un contact linéique avec le flacon 1.Beads and studs can be employed to perform similar functions. In general, a stud 162 makes it possible to obtain a small zone of contact with the bottle 1, for example an almost point-like zone of contact, while a bead 163 makes it possible to obtain a linear contact with the bottle 1.

Le bourrelet 163 présente, dans l'exemple représenté, une configuration dans laquelle il définit une forme fermée, en l'occurrence sensiblement un rectangle. Le bourrelet peut définir diverses formes fermées : cercle, ovale, carré, rectangle, ou toute autre forme. La forme rectangulaire du bourrelet 163 de l'exemple ici représenté permet de créer un appui sur le flacon 1 tout autour de l'étiquette 17 (ou de tout autre marquage rapporté sur le flacon 1) afin d'offrir une protection optimale de ce marquage.The bead 163 has, in the example shown, a configuration in which it defines a closed shape, in this case substantially a rectangle. The bead can define various closed shapes: circle, oval, square, rectangle, or any other shape. The rectangular shape of the bead 163 of the example represented here makes it possible to create a support on the bottle 1 all around the label 17 (or any other marking attached to the bottle 1) in order to offer optimal protection of this marking. .

Quatre plots 162 positionnés vers les coins du flacon 1 permettent d'obtenir également le maintien d'un espace entre le flacon (et notamment son marquage rapporté) et la paroi de la coque 6.Four studs 162 positioned towards the corners of the bottle 1 also make it possible to maintain a space between the bottle (and in particular its added marking) and the wall of the shell 6.

Lorsque le flacon est mis en place dans la coque 5, les moyens de maintien 16 peuvent être plus ou moins déformés.When the bottle is placed in the shell 5, the holding means 16 can be more or less deformed.

De manière générale, les moyens de maintien 16 peuvent être formés par une surépaisseur de la coque, ou par une déformation locale de la coque vers le volume de réception qu'elle forme.In general, the holding means 16 can be formed by an extra thickness of the shell, or by a local deformation of the shell towards the reception volume that it forms.

Dans l'exemple de mode de réalisation représenté à la figure 2 et à la figure 3, la première demi-coque 6 et la deuxième demi-coque 7 comportent chacune un bord périphérique 9 qui est au contact du bord périphérique 9 de l'autre demi-coque lorsque la coque 5 est en position fermée. La jonction des parois latérales 20 des deux demi-coques est ainsi réalisée tranche contre tranche, ou le cas échéant avec un léger recouvrement entre lesdites parois latérales 20 respectivement de la première demi-coque 6 et de la deuxième demi-coque 7.In the exemplary embodiment shown in picture 2 and at the picture 3 , the first half-shell 6 and the second half-shell 7 each have a peripheral edge 9 which is in contact with the peripheral edge 9 of the other half-shell when the shell 5 is in the closed position. The junction of the side walls 20 of the two half-shells is thus made edge against edge, or if necessary with a slight overlap between said side walls 20 respectively of the first half-shell 6 and of the second half-shell 7.

Un bord périphérique 9 très net peut-être obtenu grâce à un découpage des demi-coques à l'aide d'un outil tranchant. Un tel découpage est réalisé après le moulage des demi-coques et le cas échéant après assemblage des deux couches constitutives des demi-coques comme cela est détaillé ci-après. Ce découpage est réalisé avantageusement par lame ou par usinage mécanique, notamment par découpage par bague de découpe.A very clean peripheral edge 9 can be obtained by cutting the half-shells using a cutting tool. Such cutting is carried out after the molding of the half-shells and, where appropriate, after assembly of the two layers constituting the half-shells as detailed below. This cutting is advantageously carried out by a blade or by mechanical machining, in particular by cutting with a cutting ring.

La figure 4 représente, selon une vue schématique en trois dimensions, une coque d'emballage en position ouverte. La coque 5 de la figure 4 correspond essentiellement à celle de la figure 2, de sorte que la description des figures 2 et 3 s'applique essentiellement à la coque 5 de la figure 4, à deux exceptions près : le type d'éléments de maintien 16 utilisés dans la coque, et la présence d'une portion plane 21 dans chaque demi-coque.There figure 4 represents, according to a schematic view in three dimensions, a packaging shell in the open position. Hull 5 of the figure 4 essentially corresponds to that of the figure 2 , so that the description of figure 2 And 3 mainly applies to shell 5 of the figure 4 , with two exceptions: the type of retaining elements 16 used in the shell, and the presence of a flat portion 21 in each half-shell.

Pour ce qui concerne les éléments de maintien 16, des plots 162 sont formés sur la paroi avant 18 en lieu et place du bourrelet 163 du mode de réalisation de la figure 2 et de la figure 3. Comme précédemment expliqué, ces deux alternatives permettent l'obtention de fonctions sensiblement similaires.As regards the retaining elements 16, studs 162 are formed on the front wall 18 instead of the bead 163 of the embodiment of the picture 2 and some picture 3 . As previously explained, these two alternatives make it possible to obtain substantially similar functions.

Pour ce qui concerne les portions planes 21, chaque demi-coque 6,7 forme une concavité adaptée au flacon 1. Au lieu de présenter un bord latéral fin autour de la concavité, une portion plane 21 entoure la concavité de chaque demi-coque. Lorsque la coque 5 est en position fermée, la portion plane de la première demi-coque 6 est, sur tout ou partie de sa surface, en contact avec tout ou partie de la portion plane de la deuxième demi-coque 7. Cela permet notamment une fermeture sans jeu de la coque 5. Cela permet également de donner à la coque 5 la forme souhaitée dans le plan de contact des portions planes des deux demi-coques, à savoir ici une forme générale rectangulaire.As regards the flat portions 21, each half-shell 6.7 forms a concavity adapted to the bottle 1. Instead of having a thin lateral edge around the concavity, a flat portion 21 surrounds the concavity of each half-shell. When the shell 5 is in the closed position, the flat portion of the first half-shell 6 is, over all or part of its surface, in contact with all or part of the flat portion of the second half-shell 7. This allows in particular closing without play of the shell 5. This also makes it possible to give the shell 5 the desired shape in the plane of contact of the flat portions of the two half-shells, namely here a generally rectangular shape.

Les portions planes 21 peuvent également être employées pour garantir la fermeture de la coque 5 à l'aide d'un dispositif de verrouillage 22 adapté à maintenir la coque en position fermée. Dans l'exemple représenté à la figure 4, un orifice 23 est réalisé dans chacune des portions planes des deux demi-coques, de sorte que les orifices 23 sont alignées lorsque la coque 5 est amenée en position fermée.The flat portions 21 can also be used to guarantee the closure of the shell 5 using a locking device 22 adapted to hold the shell in the closed position. In the example shown in figure 4 , an orifice 23 is made in each of the planar portions of the two half-shells, so that the orifices 23 are aligned when the shell 5 is brought into the closed position.

Le dispositif de verrouillage 22 est positionné dans les orifices 23 et maintien les portions planes 21 respectives des deux demi-coques l'une contre l'autre, au niveau des orifices 23. Le dispositif de verrouillage peut être un système de clips rapporté. Alternativement, une seule des deux demi-coques peut comporter un orifice 23, et l'autre des deux demi-coques peut comporter une déformation adaptée à se bloquer dans l'orifice 23 pour assurer le verrouillage de la coque 5.The locking device 22 is positioned in the orifices 23 and holds the respective planar portions 21 of the two half-shells against each other, at the level of the orifices 23. The locking device can be a system of added clips. Alternatively, only one of the two half-shells may include an orifice 23, and the other of the two half-shells may include a deformation suitable for locking in the orifice 23 to ensure the locking of the shell 5.

Enfin, en alternative ou en complément de la fonction de fermeture de la coque, les portions planes peuvent être employées pour adapter le conditionnement à certains présentoirs. Par exemple un trou peut y être formé pour accrocher la coque 5 à une broche à blister, classiquement utilisée en magasin.Finally, as an alternative or in addition to the function of closing the shell, the flat portions can be used to adapt the packaging to certain displays. For example, a hole can be formed therein to attach the shell 5 to a blister pin, conventionally used in stores.

La figure 5 représente, selon une vue schématique en coupe, la coque d'emballage de la figure 2 en position fermée. La figure 5 représente plus particulièrement la coque d'emballage 1 vue selon le plan de coupe A-A représenté à la figure 4.There figure 5 represents, according to a schematic sectional view, the packaging shell of the figure 2 in closed position. There figure 5 more particularly represents the packaging shell 1 seen according to section plane AA shown in figure 4 .

Dans la position fermée, les bords latéraux 9 des demi-coques 6,7 ont été mis au contact. Du fait de la concavité des deux demi-coques 6,7, la coque 5 forme, dans la position fermée représentée à la figure 3, un volume de réception 10 configuré pour accueillir et envelopper le flacon 1. Comme cela est visible aux figures 2 et 3, le volume de réception 10 est configuré pour épouser la forme générale du flacon 1. Ainsi, lorsque le flacon 1 est dans la coque 5, il existe au maximum un très faible jeu entre la coque 5 et le flacon 1, c'est-à-dire entre la paroi intérieure 11 de la coque 5 et le flacon 1. Typiquement, un jeu maximum de 4 mm, voire moins, par exemple un jeu maximum de 1 mm peut être ménagé entre la paroi intérieure 11 de la coque 5 et le flacon 1. En outre, grâce aux moyens de maintien 16 que comporte la coque 5, le flacon est immobilisé sans jeu dans ladite coque 5.In the closed position, the side edges 9 of the half-shells 6.7 have been brought into contact. Due to the concavity of the two half-shells 6.7, the shell 5 forms, in the closed position shown in picture 3 , a receiving volume 10 configured to accommodate and wrap the bottle 1. As can be seen in the figure 2 And 3 , the receiving volume 10 is configured to match the general shape of the bottle 1. Thus, when the bottle 1 is in the shell 5, there is at most a very small clearance between the shell 5 and the bottle 1, i.e. that is to say between the inner wall 11 of the shell 5 and the bottle 1. Typically, a maximum play of 4 mm, or even less, for example a maximum play of 1 mm can be provided between the inner wall 11 of the shell 5 and the bottle 1. In addition, thanks to the holding means 16 that the shell 5 comprises, the bottle is immobilized without play in the said shell 5.

Le flacon 1 peut ainsi être introduit en force dans la coque 5, de sorte qu'il y est maintenu par frottements entre certains éléments de maintien 16 (typiquement les contreforts 161) et le flacon 1.The bottle 1 can thus be introduced by force into the shell 5, so that it is held there by friction between certain holding elements 16 (typically the buttresses 161) and the bottle 1.

La coque 5 peut être maintenue en position fermée par tout moyen connu. Par exemple, un moyen adhésif peut être appliqué à cheval entre la première demi-coque 6 et la deuxième demi-coque 7. Tout autre moyen de fermeture, réversible ou non, peut être employé. Par exemple un recouvrement local entre les bords latéraux 9 de la première demi-coque et de la deuxième demi-coque peut être prévu. Au niveau de ce recouvrement local, il est possible de former, lors du moulage des demi-coques ou après, une surépaisseur dans l'une des demi-coques venant se loger dans un logement correspondant de l'autre demi-coque. Une fermeture par clipsage peut ainsi être obtenue.The shell 5 can be kept in the closed position by any known means. For example, an adhesive means can be applied straddling the first half-shell 6 and the second half-shell 7. Any other closing means, reversible or not, can be employee. For example, a local overlap between the side edges 9 of the first half-shell and of the second half-shell can be provided. At this local overlap, it is possible to form, during the molding of the half-shells or afterwards, an extra thickness in one of the half-shells which is housed in a corresponding housing of the other half-shell. A closure by clipping can thus be obtained.

Les figures permettent d'apprécier la géométrie complexe du volume de réception 10 qu'il est possible d'obtenir dans l'invention pour correspondre à la forme générale du flacon 1. Le volume de réception 10 peut ainsi être formé d'une pluralité de volumes ayant des géométries différentes.The figures make it possible to appreciate the complex geometry of the reception volume 10 that it is possible to obtain in the invention to correspond to the general shape of the bottle 1. The reception volume 10 can thus be formed of a plurality of volumes with different geometries.

On peut ainsi distinguer, dans l'exemple représenté :

  • un volume de réception de réservoir 101,
  • un volume de réception d'un col 102,
  • un volume de réception d'un bouchon 103.
We can thus distinguish, in the example shown:
  • a reservoir receiving volume 101,
  • a volume for receiving a neck 102,
  • a volume for receiving a cap 103.

La section transversale du volume de réception évolue fortement entre ces différents volumes qui le constituent, voire dans chacun de ces volumes constitutifs. Dans l'exemple représenté, le volume de réception de réservoir a une première section transversale S1 qui a une première surface ; le volume de réception d'un col a une deuxième section transversale S2 qui a une surface inférieure à la première surface S1, et le volume de réception d'un bouchon a une troisième section transversale S3 qui a une surface comprise entre la première surface et la deuxième surface.The cross-section of the receiving volume varies greatly between these different volumes which constitute it, or even in each of these constituent volumes. In the example shown, the reservoir receiving volume has a first cross section S1 which has a first surface; the receiving volume of a neck has a second cross-section S2 which has a lower surface than the first surface S1, and the receiving volume of a plug has a third cross-section S3 which has a surface between the first surface and the second surface.

La vue en coupe de la figure 3 présente un autre aspect optionnel de l'invention.The sectional view of the picture 3 presents another optional aspect of the invention.

Il est ainsi proposé selon un mode de réalisation de l'invention une coque dont les demi-coques 6, 7 (ou chaque demi-coque si elles sont obtenues séparément) comportent deux couches. Plus particulièrement, chaque demi-coque comporte une couche interne 13 et une couche externe 14. La couche interne 13 et la couche externe 14 sont moulées indépendamment l'une de l'autre puis assemblées pour former les demi-coques.There is thus proposed according to one embodiment of the invention a shell whose half-shells 6, 7 (or each half-shell if they are obtained separately) comprise two layers. More particularly, each half-shell comprises an inner layer 13 and an outer layer 14. The inner layer 13 and the outer layer 14 are molded independently of one another and then assembled to form the half-shells.

La couche interne et la couche externe sont ainsi assemblées, emboîtées l'une dans l'autre et par exemple collées.The inner layer and the outer layer are thus assembled, nested one inside the other and for example glued.

Ainsi, les éléments de maintien 16, par exemple les plots 161 représentés à la figure 5, peuvent être obtenus par une déformation locale de la couche interne 13 uniquement. L'écrasement de l'élément de maintien est facilité et sa capacité à absorber un choc est améliorée, du fait de la présence d'un espace 24 entre les deux couches au niveau de l'élément de maintien 16. Néanmoins, l'aspect extérieur de la coque n'est pas altéré. Selon les propriétés mécaniques des matériaux envisagés, l'épaisseur de la coque offrant le niveau de protection souhaité, en particulier contre les chocs, est de l'ordre de 1 mm.Thus, the holding elements 16, for example the studs 161 shown in figure 5 , can be obtained by a local deformation of the inner layer 13 only. The crushing of the holding element is facilitated and its ability to absorb a shock is improved, due to the presence of a space 24 between the two layers at the level of the holding element 16. Nevertheless, the appearance exterior of the hull is not altered. Depending on the mechanical properties of the materials considered, the thickness of the shell offering the desired level of protection, in particular against shocks, is of the order of 1 mm.

Dans le cas d'une coque comportant une couche interne 13 et une couche externe 14 assemblées l'une à l'autre, l'épaisseur totale est obtenue par la somme de l'épaisseur de chaque couche. Par exemple, une épaisseur totale de l'ordre de 1 mm peut être obtenue par l'assemblage de deux couches ayant chacune une épaisseur de l'ordre de 0,5 mm.In the case of a shell comprising an inner layer 13 and an outer layer 14 assembled together, the total thickness is obtained by the sum of the thickness of each layer. For example, a total thickness of the order of 1 mm can be obtained by assembling two layers each having a thickness of the order of 0.5 mm.

De manière générale, et selon le flacon à protéger, une épaisseur de plus de 0,5 mm et préférentiellement de plus de 0,8 mm apparait appropriée à la protection d'un flacon de verrerie de dimensions classiques pour un parfum ou un produit cosmétique ou de toilette. Une coque ayant une épaisseur comprise entre 0,5 mm et 3 mm, préférentiellement entre 0,8 mm et 2 mm, apparait ainsi appropriée à protéger un tel flacon.In general, and depending on the bottle to be protected, a thickness of more than 0.5 mm and preferably more than 0.8 mm appears appropriate for the protection of a glassware bottle of conventional dimensions for a perfume or a cosmetic product. or toilet. A shell having a thickness of between 0.5 mm and 3 mm, preferably between 0.8 mm and 2 mm, thus appears suitable for protecting such a bottle.

La coque peut avoir une épaisseur de paroi sensiblement constante sur toute sa surface (par sensiblement constante, on entend par exemple constante à plus ou moins 0,2 mm près).The shell may have a wall thickness that is substantially constant over its entire surface (by substantially constant is meant for example constant to within plus or minus 0.2 mm).

Néanmoins, le procédé de moulage permet également de réaliser une coque ayant une paroi d'épaisseur variable, par exemple afin de protéger par une paroi d'épaisseur plus important les zones les plus fragiles ou les plus exposées du flacon (arêtes, fond, bouchon). Cette variation d'épaisseur s'ajoute à la présence d'éléments de maintien pour protéger le flacon.Nevertheless, the molding process also makes it possible to produce a shell having a wall of variable thickness, for example in order to protect by a wall of greater thickness the most fragile or most exposed areas of the bottle (edges, bottom, stopper ). This variation in thickness is added to the presence of retaining elements to protect the bottle.

La coque peut ainsi présenter une épaisseur de paroi nominale comprise entre 0,5 mm et 3 mm, de préférence de l'ordre de 1mm à 1,2mm la paroi de la coque présentant sur au moins une majorité (ou sur la totalité) de sa surface une épaisseur égale à l'épaisseur nominale à plus ou moins 0,2mm près, de préférence à plus ou moins 0,1 mm près.The shell may thus have a nominal wall thickness of between 0.5 mm and 3 mm, preferably of the order of 1 mm to 1.2 mm, the wall of the shell having on at least a majority (or all) of its surface a thickness equal to the nominal thickness to within plus or minus 0.2 mm, preferably within plus or minus 0.1 mm.

La figure 6 représente, selon une vue schématique en trois dimensions, la coque des figures 2 et 3, en position fermée.There figure 6 represents, according to a schematic view in three dimensions, the shell of the figure 2 And 3 , in the closed position.

La figure 6 permet de constater que la coque 5, qui enveloppe le flacon 1, forme une peau autour de ce flacon de sorte que la forme générale de la coque reproduit la forme extérieure du flacon et forme ainsi un écrin esthétique et distinctif pour le flacon.There figure 6 shows that the shell 5, which envelops the bottle 1, forms a skin around this bottle so that the general shape of the shell reproduces the outer shape of the bottle and thus forms an aesthetic and distinctive case for the bottle.

Comme cela est visible sur les différentes figures présentées, la technique de moulage d'une pulpe d'une ou plusieurs plantes fibreuses employée pour la formation de la coque 5 permet l'obtention de formes tridimensionnelles complexes, ayant de faibles angles de dépouilles et des arêtes bien marquées. Cela n'est pas permis par d'autres techniques de mise en forme telles que le thermoformage.As can be seen in the various figures presented, the technique of molding a pulp of one or more fibrous plants used for the formation of the shell 5 makes it possible to obtain complex three-dimensional shapes, having low angles of tapers and well-marked edges. This is not permitted by other shaping techniques such as thermoforming.

Le moulage permet également la réalisation d'un motif tridimensionnel ou d'une structure tridimensionnelle (par exemple un gaufrage) à la surface de la coque. Enfin, dans l'exemple représenté, une zone d'impression 15, destinée par exemple à l'impression d'un logo, d'une marque, d'un nom commercial, etc., est prévue sur la coque. La zone d'impression 15 peut notamment être une zone non structurée, optionnellement délimitée en étant formée en creux ou en relief vis-à-vis du reste de la coque 5. L'invention ainsi développée permet l'obtention d'un emballage secondaire pour un parfum, un produit cosmétique, ou un produit de toilette, en particulier un emballage pour flacon qui présente de nombreux avantages. Le produit, enveloppé par une coque, est correctement protégé. En particulier, les éléments de maintien que comporte la coque selon l'invention garantit un bon maintien du produit dans la coque, et participe à sa protection contre les chocs. Les tolérances de fabrication du flacon, qui sont potentiellement importantes pour un flacon de verrerie, sont compensées grâce aux éléments de maintien. L'emballage unique constitué par la coque se substitue à trois éléments d'emballage employés actuellement, à savoir l'étui, la cale, et le fourreau. Comme la coque enveloppe le flacon au plus près, elle est moins volumineuse que les emballages secondaires actuellement utilisés, ce qui réduit le volume total occupé par les produits dans leur emballage secondaire, et réduit ainsi les coûts de stockage et de transport. Enfin, le matériau constitutif de la coque d'emballage est recyclable et biodégradable.The molding also allows the production of a three-dimensional pattern or a three-dimensional structure (for example an embossing) on the surface of the shell. Finally, in the example shown, a printing zone 15, intended for example for printing a logo, a brand, a commercial name, etc., is provided on the shell. The printing zone 15 can in particular be an unstructured zone, optionally delimited by being formed in hollow or in relief vis-à-vis the rest of the shell 5. The invention thus developed makes it possible to obtain a secondary packaging for a perfume, a cosmetic product, or a toiletry product, in particular a packaging for a bottle which has numerous advantages. The product, wrapped in a shell, is properly protected. In particular, the retaining elements included in the shell according to the invention guarantee good retention of the product in the shell, and participate in its protection against shocks. The manufacturing tolerances of the bottle, which are potentially significant for a glassware bottle, are compensated by means of the holding elements. The single packaging constituted by the shell replaces three packaging elements currently used, namely the case, the wedge, and the sheath. As the shell envelops the bottle as closely as possible, it is less voluminous than the secondary packaging currently used, which reduces the total volume occupied by the products in their secondary packaging, and thus reduces storage and transport costs. Finally, the constituent material of the packaging shell is recyclable and biodegradable.
