Description

La présente invention concerne un conditionnement comportant un contenant déformable par pression et une tête de distribution apte à être rompue pour la distribution du produit contenu ainsi qu'un procédé apte à sa fabrication.The present invention relates to a packaging comprising a pressure-deformable container and a dispensable dispensing head for dispensing the contained product and a process suitable for its manufacture.

L'invention trouvera son application notamment dans le domaine du conditionnement de produits cosmétiques, pharmaceutiques ou encore alimentaires et pour la réalisation d'échantillons divers.The invention will find its application particularly in the field of packaging of cosmetic, pharmaceutical or food products and for the production of various samples.

On connaît déjà différents conditionnements essentiellement unidoses pouvant se présenter sous les formes suivantes :

  • des blisters ou blisters à deux coques, sachets thermosoudés, sachets soudés haute fréquence, etc.
    Ces réalisations génèrent toute sorte de contraintes esthétiques et de forme dont des soudures périphériques plus ou moins larges pouvant être gênantes esthétiquement.
  • des capsules de gélatine mais dont l'utilisation nécessitent des types de formulation de produit contenu quasiment anhydres
  • des tubes ou autres containers injectés à la forme définie ou à la géométrie typée ou encadrée qui ne peuvent donc pas être dans tous les cas satisfaisants.
  • les produits couramment dénommés BFS (Blow-Fill-Seal) qui impliquent des coûts et des délais de développement d'outillage très élevés, essentiellement utilisés pour des remplissages stériles lourds à mettre au point et uniquement pour des contenus à forte valeur ajoutée.
Various essentially unidose packages are already known which can be in the following forms:
  • double-blister blisters or blisters, heat-sealed pouches, high-frequency welded bags, etc.
    These achievements generate all kinds of aesthetic constraints and shape of which more or less wide peripheral welds can be inconvenient aesthetically.
  • gelatin capsules but whose use require types of product formulation contained almost anhydrous
  • tubes or other containers injected in the defined form or geometry typed or framed which can not be in any case satisfactory.
  • products commonly referred to as BFS (Blow-Fill-Seal) which involve very high tool development costs and delays, mainly used for heavy sterile fillings to be developed and only for high added value contents.

Par ailleurs, ces produits ont une esthétique très typée et limitée aux machines existantes et à la production en barrettes.Moreover, these products have a very typical aesthetic and limited to existing machines and production bars.

D'une façon générale, différents contenants sont connus avec un volume intérieur obturé par un bouchon apte à être rompu et présentant à l'extrémité opposée un canal de remplissage.In general, different containers are known with an interior volume closed by a plug capable of being broken and having at the opposite end a filling channel.

Le canal de remplissage est généralement formé dans la même phase de fabrication que le contenant et est supprimé une fois le remplissage opéré.The filling channel is generally formed in the same manufacturing phase as the container and is removed once the filling operation.

Ce type de conditionnement a également des applications et des formes très limitées et nécessitent différentes opérations additionnelles pour le remplissage (réalisation d'un canal d'écoulement, remplissage, suppression du canal d'écoulement et soudage pour boucher l'ouverture correspondante).This type of packaging also has very limited applications and forms and requires different additional operations for filling (making a flow channel, filling, removing the flow channel and welding to plug the corresponding opening).

Le document WO-A-96 22919 décrit un conteneur pourvu d'une partie de contenant déformable surmontée d'une tête formant capuchon dans laquelle une canule de passage de produit est ménagée. La partie de contenant et la tête sont assemblées par des moyens mécaniques de solidarisation par obstacle. Ce type de solidarisation implique des formes complexes et donc coûteuses pour les portions coopérant. La tenue mécanique de l'assemblage est par ailleurs fonction des matériaux des portions coopérant et l'étanchéité n'est pas facile à obtenir.WO-A-9622919 discloses a container provided with a deformable container portion surmounted by a cap head in which a product passage cannula is provided. The container portion and the head are assembled by mechanical means for securing by obstacle. This type of joining implies complex shapes and therefore expensive for the cooperating portions. The mechanical strength of the assembly is also a function of the materials of the cooperating portions and the seal is not easy to obtain.

L'invention permet de remédier aux inconvénients des conditionnements connus jusqu'à présent.The invention overcomes the disadvantages of the known packages so far.

Elle propose pour ce faire un nouveau conditionnement qui a l'avantage de présenter très peu de contraintes de forme.To this end, it proposes a new packaging that has the advantage of presenting very few form constraints.

On peut ainsi constituer des conditionnements de formes très variées répondant aux attentes du service marketing et des utilisateurs.It can thus be packaging very varied forms that meet the expectations of the marketing department and users.

Un autre avantage de l'invention est de réduire fortement le coût de fabrication de tels conditionnements.Another advantage of the invention is to greatly reduce the manufacturing cost of such packaging.

Cet élément est notamment décisif dans le cas de réalisations de conditionnements unidoses où le coût de fabrication doit être peu élevé.This element is particularly decisive in the case of achievements of single-dose packages where the manufacturing cost must be low.

Les dessins ci-joints sont donnés à titre d'exemples et ne sont pas limitatifs de l'invention. Ils représentent deux modes de réalisation de l'invention et permettront de la comprendre aisément.The accompanying drawings are given by way of example and are not limiting of the invention. They represent two embodiments of the invention and will make it easy to understand.

La figure 1 est une vue en perspective générale du conditionnement selon l'invention.Figure 1 is a general perspective view of the packaging according to the invention.

La figure 2 et 3 en sont respectivement une vue de dessus et une vue de côté.Figures 2 and 3 are respectively a top view and a side view.

La figure 4 et 5 sont en coupe du conditionnement selon l'invention.Figure 4 and 5 are in section of the packaging according to the invention.

La figure 6 et 7 en sont une illustration en détail.Figure 6 and 7 are an illustration in detail.

Les figures 8 à 10 montrent un deuxième mode de réalisation de l'invention.Figures 8 to 10 show a second embodiment of the invention.

La figure 11 illustre un troisième mode de réalisation de l'invention.Figure 11 illustrates a third embodiment of the invention.

D'une façon générale, le conditionnement 1 de l'invention permet un assemblage efficace de l'embout 5 et du col 4 constituant la tête. Cet assemblage est opéré par solidarisation de deux surfaces d'appui (l'une sur le col 4, l'autre sur l'embout 5) après leur mise en contact. Une technique de soudage est employée avantageusement à cet effet.In a general manner, the packaging 1 of the invention allows an effective assembly of the tip 5 and the neck 4 constituting the head. This assembly is operated by joining two bearing surfaces (one on the neck 4, the other on the end 5) after their contacting. A welding technique is advantageously used for this purpose.

A titre préféré, on assure un guidage de l'embout 5 sur le col 4 lors du montage.As a preference, it ensures a guide of the nozzle 5 on the neck 4 during assembly.

Ce guidage peut être produit par coopération des surfaces latérales du col 4 et de l'embout 5 (en particulier par la surface d'une jupe 6 intérieure ou extérieure sur l'embout 5 et une paroi, intérieure ou extérieure, du col 4).This guidance can be produced by cooperation of the lateral surfaces of the neck 4 and the endpiece 5 (in particular by the surface of an inner or outer skirt 6 on the endpiece 5 and a wall, inside or outside, of the neck 4). .

On notera que l'ajustement entre ces surfaces peut être légèrement serré (pour participer à la solidarisation) ou au contraire est glissant afin de ne produire qu'un simple guidage axial.It should be noted that the adjustment between these surfaces can be slightly tightened (to participate in the joining) or on the contrary is slippery in order to produce only a simple axial guidance.

On décrit ci-après un premier mode de réalisation de l'invention.A first embodiment of the invention is described below.

En référence à la figure 1, le conditionnement ici présenté comprend un contenant déformable par pression 2 ici configuré sous forme de poche souple notamment réalisable par soufflage.With reference to FIG. 1, the packaging presented here comprises a pressure-deformable container 2 here configured in the form of a flexible bag that can be produced by blowing in particular.

Le conditionnement 1 comprend en outre une tête de distribution 3 fermant le contenant déformable par pression 2 et apte à être ouverte pour la distribution du produit.The packaging 1 further comprises a dispensing head 3 closing the pressure-deformable container 2 and able to be opened for dispensing the product.

Tel que visible sous les différentes figures, aucune autre ouverture n'est nécessaire pour la réalisation de la phase de remplissage du contenant.As visible in the various figures, no other opening is necessary for carrying out the filling phase of the container.

La tête de distribution 3 est à cet effet réalisée en deux parties assemblables une fois que le remplissage est opéré.The dispensing head 3 is for this purpose made in two parts assembled once the filling is operated.

La première partie de la tête de distribution 3 est constituée par un col 4 solidaire du contenant et délimitant un orifice.The first part of the dispensing head 3 is constituted by a neck 4 integral with the container and defining an orifice.

De façon avantageuse, le col 4 est réalisé lors de l'étape de fabrication du contenant 2 et formé dans sa matière.Advantageously, the neck 4 is made during the step of manufacturing the container 2 and formed in its material.

Le col 4 définit une saillie disposant d'une paroi extérieure 7 notamment visible en figure 6.The neck 4 defines a projection having an outer wall 7, particularly visible in FIG.

Par ailleurs, le col peut comprendre une zone 13 de rigidité apte à rendre plus massif le corps du col 4 et éviter sa déformation intempestive lors des manipulations.Furthermore, the collar may include a zone 13 of rigidity capable of making the body of the neck 4 more massive and avoid its inadvertent deformation during handling.

La tête de distribution 3 comprend en outre un embout 5 comportant une jupe 6 apte à coopérer (avec un ajustement non serré) avec la paroi extérieure 7 du col 4.The dispensing head 3 further comprises a tip 5 having a skirt 6 adapted to cooperate (with a non-tight fit) with the outer wall 7 of the neck 4.

L'embout 5 est donc emmanché sur le col 4 jusqu'à parvenir préférentiellement à un rebord 12 comprenant ou non cordon de soudure 11 pour la solidarisation définitive de la jupe 6 sur le col 4.The end piece 5 is thus fitted onto the neck 4 until it preferably reaches a rim 12 comprising or not a weld bead 11 for the final joining of the skirt 6 to the neck 4.

Le soudage opéré peut être réalisé par une technique à ultrasons ou encore par friction.The welding performed can be performed by an ultrasound technique or by friction.

Toute autre forme connue de soudage peut être également utilisée.Any other known form of welding can also be used.

L'embout 5 comporte également préférentiellement une partie centrale 8 également visible aux figures et notamment aux figures 6 et 7.The tip 5 also preferably comprises a central portion 8 also visible in the figures and in particular in Figures 6 and 7.

La partie centrale 8 a pour destination de s'insérer dans l'orifice formé par le col 4 et préférentiellement de s'appliquer sur la paroi interne de ce col.The central portion 8 is intended to be inserted in the orifice formed by the neck 4 and preferably to be applied on the inner wall of this neck.

Pour faciliter l'emmanchement, la partie centrale 8 peut avoir une forme tronconique.To facilitate the fitting, the central portion 8 may have a frustoconical shape.

Pour permettre l'évacuation du produit contenu, la partie centrale 8 comprend en outre un canal d'écoulement 9 débouchant à une extrémité dans le volume intérieur du contenant 2 et obturé à son autre extrémité.To allow the evacuation of the contained product, the central portion 8 further comprises a flow channel 9 opening at one end into the interior volume of the container 2 and closed at its other end.

Cette obturation peut être produite par une zone d'extrémité 10 apte à être rompue de conception courante.This closure can be produced by a rupturable end zone 10 of common design.

L'embout 5 sera adapté à la destination du conditionnement.The tip 5 will be adapted to the destination of the packaging.

Notamment, il est possible de calibrer ou d'aménager le canal d'écoulement 9 de façon à obtenir des performances spécifiques de quantité (telles des gouttes calibrées) ou de type de sortie de produit (tel un spray).In particular, it is possible to calibrate or arrange the flow channel 9 so as to obtain specific performance in quantity (such as calibrated drops) or product output type (such as a spray).

Il est également possible d'adjoindre ou de former dans l'embout un applicateur de produit.It is also possible to add or form in the tip a product applicator.

Le procédé ici présenté est apte à la fabrication du conditionnement 1 précédemment décrit.The method presented here is suitable for manufacturing the packaging 1 previously described.

A titre préférentiel, le procédé comprend une étape de remplissage du contenant 2 après la formation du contenant avec le col mais avant l'assemblage de l'embout 5 sur le col 4.Preferably, the method comprises a step of filling the container 2 after the formation of the container with the neck but before the assembly of the tip 5 on the neck 4.

De cette façon, on utilise la même ouverture pour le remplissage que pour la fixation de la tête de distribution 3.In this way, the same opening for filling is used as for fixing the dispensing head 3.

Le remplissage et l'assemblage peuvent être effectués en ligne par une machine semi automatique ou automatique approvisionnant les contenants 2, les marquant au jet d'encre des mentions légales nécessaires, remplissant, approvisionnant les embouts, les soudant, notamment par une technique à ultrasons sur les contenants 2.The filling and assembly can be done online by a semi-automatic or automatic machine supplying the containers 2, ink-jet marking the necessary legal information, filling, supplying the tips, welding, including an ultrasonic technique on containers 2.

En se référant maintenant aux figures 8 à 10, on décrit un autre mode de réalisation du conditionnement 1.Referring now to FIGS. 8 to 10, another embodiment of the package 1 is described.

Suivant cette possibilité, le rebord 12 est interne au col 4 et constitue une surface d'appui pour l'extrémité distale d'une jupe 6 apte à s'insérer dans l'orifice du col 4.According to this possibility, the flange 12 is internal to the neck 4 and constitutes a bearing surface for the distal end of a skirt 6 adapted to fit into the orifice of the neck 4.

Avantageusement, l'embout 5 comporte en outre une partie périphérique 14 entourant la zone de jonction entre le col 4 et l'embout 5 et recouvrant l'extrémité distale du col 4.Advantageously, the tip 5 further comprises a peripheral portion 14 surrounding the junction zone between the neck 4 and the tip 5 and covering the distal end of the neck 4.

De cette façon, les parties assemblées sont parfaitement masquées de l'extérieur.In this way, the assembled parts are perfectly hidden from the outside.

Hormis ces différences, le conditionnement 1 selon cette variante pourra être formé de façon semblable au mode de réalisation précédemment décrit.Apart from these differences, the packaging 1 according to this variant may be formed similarly to the embodiment described above.

On notera que la surface d'appui de l'embout 5 peut aussi être formée par un rebord faisant saillie sur sa paroi interne ou externe et sur lequel l'extrémité distale du col 4 vient s'appliquer.Note that the bearing surface of the tip 5 may also be formed by a rim projecting from its inner or outer wall and on which the distal end of the neck 4 is applied.

Dans cette optique, on décrit maintenant un troisième mode de réalisation de l'invention illustré à la figure 11.In this respect, a third embodiment of the invention illustrated in FIG. 11 is now described.

A cette figure, le rebord 12 de soudage du col 4 est constitué par l'épaisseur de l'extrémité distale du col 4. Cette extrémité vient s'appliquer pour soudage sur le rebord 17 formé ici à l'extérieur de la jupe 6. Dans le cas représenté, une partie périphérique 14 est présente (comme dans le deuxième mode de réalisation), ce qui induit que le rebord 17 est en interposition entre la jupe 6 et la partie périphérique 14.In this figure, the flange 12 for welding the neck 4 is constituted by the thickness of the distal end of the neck 4. This end is applied for welding on the flange 17 formed here on the outside of the skirt 6. In the case shown, a peripheral portion 14 is present (as in the second embodiment), which induces that the flange 17 is interposed between the skirt 6 and the peripheral portion 14.

De façon avantageuse, la coopération des parois du col 4 et de la jupe 6 est réalisée pour préserver une réservation interne 15 isolant la zone de soudage du volume de réception du produit du contenant 2.Advantageously, the cooperation of the walls of the neck 4 and the skirt 6 is performed to preserve an internal reservation 15 isolating the welding zone from the receiving volume of the product of the container 2.

A titre d'exemple, on a représenté en figure 11 une réservation interne 15 formée entre la paroi interne du col 4 et la paroi externe de la jupe 6 et délimitée en partie basse par un décrochement 16 du col 4 réalisé par augmentation de l'épaisseur du col 4 à ce niveau, ce qui participe en outre à la rigidité du col 4 sous forme de zone de rigidification 13.By way of example, FIG. 11 shows an internal reservation 15 formed between the inner wall of the neck 4 and the outer wall of the skirt 6 and delimited at the bottom by a recess 16 of the neck 4 made by increasing the thickness of the neck 4 at this level, which further contributes to the rigidity of the neck 4 as a stiffening zone 13.

On aurait pu former un décrochement sur la paroi externe de la jupe 6 sans sortir du cadre de l'invention.It could have formed a recess on the outer wall of the skirt 6 without departing from the scope of the invention.

La réservation interne 15 évite toute contamination du produit contenu par des projections de matière produites lors de l'opération de soudage. Des résidus de matière plastique peuvent en effet être produits par le soudage, notamment par friction.The internal reservation 15 avoids contamination of the product contained by projections of material produced during the welding operation. of the Plastic residues can indeed be produced by welding, especially by friction.

Un ajustement serré du col 4 et du bas de la jupe 6 n'est pas forcément nécessaire pour que la réservation 15 fasse effet. Un léger jeu peut subsister.A tight fit of the neck 4 and the bottom of the skirt 6 is not necessarily necessary for the reservation 15 to take effect. A slight game can survive.

Un tel conditionnement et son procédé de fabrication ont l'avantage d'avoir des performances économiques élevées ce qui multiplie les applications possibles notamment pour les conditionnements vendus en de multiples quantités tels que des échantillons publicitaires ou des conditionnements unidoses divers.Such packaging and its manufacturing process have the advantage of having high economic performance which multiplies the possible applications especially for packaging sold in multiple quantities such as advertising samples or various single-dose packaging.
