Description

"Conditionnement comportant un contenant déformable par pression et procédé de fabrication" "Packaging comprising a container deformable by pressure and manufacturing process"
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 container deformable by pressure and a dispensing head capable of being broken for the distribution of the product contained, as well as 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 in particular in the field of packaging of cosmetic, pharmaceutical or even food products and for the production of various samples.
On connaît déjà différents conditionnements essentiellement unidoses pouvant se présenter sous les formes suivantes :We already know different essentially single-dose packaging which can take the following forms:
- des blisters ou blisters à deux coques, sachets thermosoudés, sachets soudés haute fréquence, etc.- blisters or blisters with two shells, heat-sealed bags, high-frequency welded bags, etc.
Ces réalisations génèrent toute sorte de contraintes esthétiques et de forme dont des soudures périphériques plus ou moins larges pouvant être gênantes esthétiquement.These achievements generate all kinds of aesthetic and shape constraints, including more or less wide peripheral welds which can be aesthetically annoying.
- des capsules de gélatine mais dont l'utilisation nécessitent des types de formulation de produit contenu quasiment anhydres- gelatin capsules but the use of which requires almost anhydrous types of product content
- 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.- tubes or other containers injected with the defined shape or with the typed or framed geometry which cannot therefore be satisfactory in all cases.
- 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.- products commonly called BFS (Blow-Fill-Seal) which involve very high tool development costs and times, mainly used for sterile fillings which are heavy to develop and only for contents with high added value.
Par ailleurs, ces produits ont une esthétique très typée et limitée aux machines existantes et à la production en barrettes. 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 addition, these products have a very distinctive aesthetic and are limited to existing machines and to production in strips. In general, various containers are known with an internal 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. 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).The filling channel is generally formed in the same manufacturing phase as the container and is removed once the filling has taken place. This type of packaging also has very limited applications and shapes and requires different additional operations for filling (making a flow channel, filling, removing the flow channel and welding to plug the corresponding opening).
L'invention permet de remédier aux inconvénients des conditionnements connus jusqu'à présent.The invention makes it possible to remedy the drawbacks of the packaging known up to now.
Elle propose pour ce faire un nouveau conditionnement qui a l'avantage de présenter très peu de contraintes de forme.To do this, it proposes a new packaging which has the advantage of having very few shape constraints.
On peut ainsi constituer des conditionnements de formes très variées répondant aux attentes du service marketing et des utilisateurs. Un autre avantage de l'invention est de réduire fortement le coût de fabrication de tels conditionnements.We can thus create packaging of very varied forms that meet the expectations of the marketing department and users. Another advantage of the invention is to greatly reduce the cost of manufacturing 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 realizations of single-dose packaging where the manufacturing cost must be low.

La figure 2 et 3 en sont respectivement une vue de dessus et une vue de côté.Figure 1 is a general perspective view of the packaging according to the invention. Figure 2 and 3 are respectively a top view and a side view.

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.FIG. 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 general, the packaging 1 of the invention allows efficient assembly of the nozzle 5 and the neck 4 constituting the head. This assembly is carried out by securing two bearing surfaces (one on the neck 4, the other on the nozzle 5) after they are brought into contact. 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, the tip 5 is guided 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). 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.This guidance can be produced by cooperation of the lateral surfaces of the neck 4 and of the end piece 5 (in particular by the surface of an interior or exterior skirt 6 on the end piece 5 and a wall, inside or outside, of the neck 4) . Note 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. 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.A first embodiment of the invention is described below. With reference to FIG. 1, the packaging presented here comprises a container that can be deformed by pressure 2 here configured in the form of a flexible bag, in particular achievable by blowing.
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 container deformable by pressure 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 shown 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. La première partie de la tête de distribution 3 est constituée par un col 4 solidaire du contenant et délimitant un orifice.The dispensing head 3 is for this purpose produced in two assemblable parts once the filling is carried out. The first part of the dispensing head 3 is constituted by a neck 4 secured to the container and delimiting 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 produced during the step of manufacturing the container 2 and formed from 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 in particular visible in FIG. 6.
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 neck may include a zone 13 of rigidity capable of making the body of the neck 4 more massive and preventing its untimely 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 nozzle 5 comprising a skirt 6 capable of cooperating (with an loose 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. Le soudage opéré peut être réalisé par une technique à ultrasons ou encore par friction.The end piece 5 is therefore fitted onto the neck 4 until preferably reaching a flange 12 with or without a weld bead 11 for the final connection of the skirt 6 on the neck 4. The welding carried out can be carried out by a technique to ultrasonic or friction.
Toute autre forme connue de soudage peut être également utilisée. L'embout 5 comporte également préférentiellement une partie centrale 8 également visible aux figures et notamment aux figures 6 et 7.Any other known form of welding can also be used. The endpiece 5 also preferably comprises a central part 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. Pour faciliter l'emmanchement, la partie centrale 8 peut avoir une forme tronconique.The central part 8 is intended to be inserted into the orifice formed by the neck 4 and preferably to be applied to the internal wall of this neck. To facilitate fitting, the central part 8 can 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. Cette obturation peut être produite par une zone d'extrémité 10 apte à être rompue de conception courante.To allow the evacuation of the product contained, the central part 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. This closure can be produced by an end zone 10 capable of being broken of current design.
L'embout 5 sera adapté à la destination du conditionnement.The end piece 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 terms of quantity (such as calibrated drops) or type of product outlet (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 a product applicator in the nozzle.
Le procédé ici présenté est apte à la fabrication du conditionnement 1 précédemment décrit. 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.The process presented here is suitable for manufacturing the packaging 1 described above. Preferably, the method comprises a step of filling the container 2 after the container has been formed with the neck but before the end piece 5 is assembled 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. 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. En se référant maintenant aux figures 8 à 10, on décrit un autre mode de réalisation du conditionnement 1. 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.In this way, the same opening is used for filling as for fixing the dispensing head 3. The filling and assembly can be carried out online by a semi-automatic or automatic machine supplying the containers 2, marking them with a jet. ink the necessary legal notices, filling, supplying the end pieces, welding them, in particular by an ultrasonic technique on the containers 2. Referring now to FIGS. 8 to 10, another embodiment of the packaging 1 is described. According to this possibility, the rim 12 is internal to the neck 4 and constitutes a bearing surface for the distal end of a skirt 6 capable of fitting 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 end piece 5 further comprises a peripheral part 14 surrounding the junction zone between the neck 4 and the end piece 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 can be formed in a similar manner 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.It will be noted that the bearing surface of the end piece 5 can also be formed by a rim projecting from its internal or external 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.With this in mind, a third embodiment of the invention is now described, illustrated in FIG. 11.
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 rim 12 for welding the neck 4 is formed by the thickness of the distal end of the neck 4. This end is applied for welding on the rim 17 formed here outside the skirt 6. In the case shown, a peripheral part 14 is present (as in the second embodiment), which means that the rim 17 is in interposition between the skirt 6 and the peripheral part 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. 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. On aurait pu former un décrochement sur la paroi externe de la jupe 6 sans sortir du cadre de l'invention.Advantageously, the cooperation of the walls of the neck 4 and of the skirt 6 is carried out to preserve an internal reservation 15 isolating the welding zone from the volume for receiving the product from the container 2. By way of example, FIG. 11 an internal reservation 15 formed between the internal wall of the neck 4 and the external wall of the skirt 6 and delimited in the lower part by a recess 16 of the neck 4 produced by increasing the thickness of the neck 4 at this level, which contributes in addition to the rigidity of the neck 4 in the form of a stiffening zone 13. It would have been possible to form a recess on the external 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 any contamination of the product contained by projections of material produced during the welding operation. of the plastic residues can indeed be produced by welding, in particular 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 collar 4 and the bottom of the skirt 6 is not necessarily necessary for the reservation 15 to take effect. A slight play may remain.
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 in particular for packaging sold in multiple quantities such as advertising samples or various single-dose packaging.
