Abstract

The invention concerns a packaging tube for pasty product, comprising a tubular skirt extending along an axial direction and sealed by swaging at the end of the tube, and a head located at the other end of the tube, the head including a dispensing passage and a neck forming a radial extension of the dispensing passage, the neck being connected to the skirt by a connecting surface. The skirt and the connecting surface have, respectively, a circumference and a radius of curvature such that the ratio of the circumference over the radius is not more than 20.

Description

La présente invention concerne de façon générale les emballages en forme de tube, traditionnellement utilisés pour le conditionnement des produit pâteux tels que dentifrice, produits pharmaceutiques, crèmes et produits divers de cosmétologie, produits alimentaires, colles, mastics, etc.The present invention relates generally to traditionally used tube-shaped packaging for the packaging of pasty products such as toothpaste, pharmaceuticals, creams and miscellaneous products cosmetology, food products, adhesives, sealants, etc.

Plus précisément, l'invention concerne un tube de conditionnement comprenant : une jupe tubulaire allongée suivant une direction axiale, cette jupe présentant une extrémité de remplissage obturée par écrasement de la jupe suivant une direction transversale et formant une première extrémité du tube; et une tête située à une seconde extrémité du tube, distante de l'extrémité de remplissage, cette tête comprenant elle-même un canal de distribution du produit pâteux et une encolure formant une extension radiale du canal de distribution, l'encolure se raccordant à la jupe par une surface de raccordement, la surface de raccordement présentant, dans un plan longitudinal contenant la direction axiale et perpendiculaire à la direction transversale, un rayon minimal déterminé, et la jupe présentant, dans un plan transversal à la direction axiale et situé à mi-distance entre les extrémités du tube, une circonférence déterminée et une épaisseur sensiblement constante.More specifically, the invention relates to a packaging tube comprising: an elongated tubular skirt according to an axial direction, this skirt having one end filling closed by crushing the following skirt a transverse direction and forming a first end tube; and a head located at a second end of the tube, distant from the filling end, this head including a product distribution channel pasty and a neck forming a radial extension of the canal distribution, the neck connecting to the skirt by a connection surface, the connection surface having, in a longitudinal plane containing the direction axial and perpendicular to the transverse direction, a determined minimum radius, and the skirt having, in a plane transverse to the axial direction and located halfway between the ends of the tube, a circumference determined and a substantially constant thickness.

Un problème général rencontré dans l'utilisation courante des tubes réside dans le fait qu'il est impossible de les vider intégralement de leur contenu, ce dont il résulte une perte de produit conditionné dont les effets négatifs, à la fois au plan économique et au plan écologique, sont inévitables.A general problem encountered in everyday use of tubes is that it is impossible to emptying them entirely of their content, which results a loss of packaged product, the negative effects of which, both economically and ecologically, are inevitable.

Un tube du type défini ci-dessus est par exemple schématiquement décrit dans le document de brevet DE-2914370 pour résoudre ce problème.A tube of the type defined above is for example schematically described in patent document DE-2914370 to resolve this problem.

Bien que la solution que propose ce brevet, et qui consiste à réduire l'angle entre l'encolure et l'axe du tube, soit à la fois utile et relativement efficace, l'ajustement du paramètre que constitue cet angle ne permet pas de résoudre le problème évoqué ci-dessus dans tous les cas de figures, c'est-à-dire avec des tubes de tailles diverses, constitués de matériaux divers et renfermant des produits de viscosités diverses.Although the solution offered by this patent, and which consists in reducing the angle between the neck and the axis of the tube, which is both useful and relatively effective, adjusting the parameter of this angle does not allow not to solve the problem mentioned above in all cases, that is to say with tubes of various sizes, made of various materials and containing products of various viscosities.

On connaít par ailleurs, par exemple par les documents de brevets WO 96/30272 et FR 2 105 590, des flacons tubulaires souples qui, bien que présentant des variations d'épaisseur sensibles suivant une direction transversale et n'appartenant donc pas au type de tubes défini ci-dessus, visent à résoudre le même problème.We also know, for example by documents WO 96/30272 and FR 2 105 590, tubular bottles flexible which, although showing variations of appreciable thickness in a transverse direction and therefore not belonging to the type of tubes defined above, aim to solve the same problem.

En réalité ces récipients non seulement posent des problèmes de fabrication relativement aigus, mais ils se trouvent aussi soumis à un compromis insoluble entre le risque d'un défaut d'étanchéité à l'air des zones de moindre épaisseur, la nécessité, pour éviter ce risque, d'augmenter la surépaisseur des zones de plus forte épaisseur, et le besoin industriel de réaliser les tubes avec un minimum de matière.In reality these containers not only pose relatively acute manufacturing problems, but they also find themselves subject to an insoluble compromise between the risk of air tightness failure in areas of least thickness, the need, to avoid this risk, to increase the excess thickness of the zones of greatest thickness, and the industrial need to produce tubes with a minimum of matter.

L'invention se situe dans ce contexte et a pour but de proposer un tube à vidage intégral permettant de pallier les limitations et problèmes évoqués ci-dessus.The invention is situated in this context and aims to offer a full drain tube to overcome the limitations and problems discussed above.

A cette fin, le tube de l'invention, par ailleurs conforme à la définition qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce que le rapport de la circonférence déterminée au rayon minimal est inférieur à vingt (c'est-à-dire moins de 6.π) et préférablement au plus égal à dix (c'est-à-dire à peine plus de 3.π).To this end, the tube of the invention, moreover conforms the definition given in the preamble above, is essentially characterized in that the ratio of the circumference determined at minimum radius is less than twenty (i.e. less than 6.π) and preferably at most equal to ten (i.e. just over 3.π).

En outre, l'encolure présente de préférence, par rapport à la direction axiale, une inclinaison maximale inférieure à 60 degrés.In addition, the neck preferably has, relative to in the axial direction, a lower maximum tilt at 60 degrees.

En pratique, il peut même s'avérer utile de donner à la surface de raccordement, par rapport à la direction axiale, une inclinaison maximale au plus égale à 45 degrés, ou même au plus égale à 30 degrés.In practice, it may even be useful to give the connection surface, in relation to the direction axial, a maximum inclination at most equal to 45 degrees, or even at most equal to 30 degrees.

Pour accroítre encore la facilité d'utilisation du tube de l'invention, il est en outre possible de faire en sorte que le rapport de l'épaisseur moyenne de l'encolure à l'épaisseur moyenne de la jupe soit au plus égal à 2.To further increase the ease of use of the tube of the invention, it is further possible to make so that the ratio of the average thickness of the neck to the average thickness of the skirt is at most equal to 2.

Selon un mode de réalisation préféré, la jupe et la tête sont réalisées d'une seule pièce, sans zone de raccord. According to a preferred embodiment, the skirt and the head are made in one piece, without connection area.

Dans le cas qui correspond à l'application privilégiée de l'invention, et dans lequel le tube est réalisé par injection d'un matériau thermoplastique et doit être rendu étanche à l'air pour assurer la protection de son contenu, ce tube est de préférence recouvert sur toute sa surface, y compris la tête, d'un vernis de protection dit " vernis barrière " , par exemple déposé par projection.In the case that corresponds to the preferred application of the invention, and in which the tube is produced by injection of a thermoplastic material and must be returned airtight to protect its contents, this tube is preferably covered over its entire surface, including including the head, a protective varnish called "varnish barrier ", for example deposited by projection.

Contrairement à ce qui est le cas dans l'art antérieur, dans lequel les jupes de tubes sont obtenues par extrusion, il est possible dans l'invention de définir la jupe par une génératrice non parallèle à la direction axiale du tube.Contrary to what is the case in the prior art, in which the tube skirts are obtained by extrusion, it is possible in the invention to define the skirt by a generator not parallel to the direction axial of the tube.

Enfin, le confort d'utilisation du tube de l'invention, en particulier en fin d'utilisation, se trouve encore amélioré en choisissant, pour la réalisation de la jupe et la tête, un matériau élastiquement étirable et présentant donc une souplesse très satisfaisante.Finally, the comfort of use of the tube the invention, in particular at the end of use, is found further improved by choosing, for the realization of the skirt and head, an elastically stretchable material with therefore a very satisfactory flexibility.

    • Other characteristics and advantages of the invention will emerge clearly from the description which is given below, for information and in no way limitative, with reference to the appended drawings, in which

    • Comme le montrent toutes les figures, l'invention concerne de façon générale un tube de conditionnement de produit pâteux, comprenant essentiellement une jupe tubulaire 1 et une tête 2.As all the figures show, the invention relates generally a product packaging tube pasty, essentially comprising a tubular skirt 1 and a head 2.

    Dans un mode de réalisation préféré, la tête 2 et la jupe 1 sont réalisées d'une seule pièce, sans zone de raccord.In a preferred embodiment, the head 2 and the skirt 1 are made in one piece, without connection zone.

    La jupe présente une forme allongée suivant une direction axiale XX' et se termine par une extrémité de remplissage 121 qui, après injection du produit à conditionner, est obturée par écrasement de cette jupe 1, éventuellement à chaud, suivant une direction transversale ZZ'.The skirt has an elongated shape in a direction axial XX 'and ends with a filling end 121 which, after injection of the product to be packaged, is closed by crushing this skirt 1, possibly hot, in a transverse direction ZZ '.

    La tête 2, qui est située à l'extrémité 122 du tube distante de l'extrémité de remplissage 121, comprend un canal de distribution 3 du produit conditionné, et une encolure 4 qui forme une extension radiale du canal 3 et qui se raccorde à la jupe 1 par une surface de raccordement 5.Head 2, which is located at the end 122 of the tube distant from the filling end 121, includes a channel distribution 3 of the packaged product, and a neck 4 which forms a radial extension of channel 3 and which is connected to the skirt 1 by a connection surface 5.

    Le problème rencontré pour vider, en fin d'utilisation, les tubes de l'art antérieur est illustré aux figures 1 et 2 et réside dans l'impossibilité d'écraser la tête pour en faire sortir le produit qui s'y trouve encore.The problem encountered in emptying, at the end of use, the tubes of the prior art is illustrated in Figures 1 and 2 and resides in the impossibility of overwriting head to bring out the product that is still there.

    Pour limiter la perte de produit qu'engendre le conditionnement en tube, la solution traditionnellement adoptée dans l'art antérieur consiste à réduire le volume du produit non susceptible d'être expulsé du tube en fin d'utilisation.To limit the loss of product caused by packaging in tube, the traditionally adopted solution in the prior art consists in reducing the volume of the product not likely to be expelled from the tube at the end use.

    Ainsi, l'approche connue la plus classique a toujours conduit à prévoir que la plus grande pente de l'encolure 4 et de la surface de raccordement 5 fassent, par rapport à la direction axiale XX', un angle A correspondant à une inclinaison aussi importante que possible et en tout cas égale à 60 degrés.So the most classic known approach has always leads to predict that the greatest slope of the neck 4 and of the connection surface 5 do, with respect to the axial direction XX ', an angle A corresponding to an inclination as important as possible and in any case equal to 60 degrees.

    La présente invention, qui comme le document DE-2914370 procède de la démarche exactement inverse et qui cherche non pas à réduire le volume perdu de produit conditionné, mais à éviter toute perte de produit, préconise au contraire de faire en sorte, de préférence, que l'encolure 4 présente, par rapport à la direction axiale XX', une inclinaison maximale A inférieure à 60 degrés.The present invention, which as the document DE-2914370 proceeds from the exact opposite approach and which does not seek to reduce the lost volume of packaged product, but to avoid any loss of product, recommends contrary to preferably ensuring that the neckline 4 has, with respect to the axial direction XX ', an inclination maximum A less than 60 degrees.

    Suivant le matériau utilisé pour réaliser le tube et l'épaisseur de la tête, il peut même être conseillé de donner à la surface de raccordement 5, par rapport à la direction axiale XX', une inclinaison maximale B au plus égale à 45 degrés, et même éventuellement au plus égale à 30 degrés.Depending on the material used to make the tube and the thickness of the head, it may even be advisable to give to the connection surface 5, relative to the direction axial XX ', a maximum inclination B at most equal to 45 degrees, and even possibly at most equal to 30 degrees.

    Mais en toute hypothèse, l'invention prévoit d'associer à ces caractéristiques préférentielles un choix particulier de paramètres relatifs à la forme générale du tube, permettant d'utiliser pour la fabrication du tube des matériaux de déformabilités diverses.But in any event, the invention provides to associate with these preferential characteristics a choice particular parameters relating to the general shape of the tube, allowing to use for the manufacture of the tube various deformability materials.

    Le premier paramètre à prendre en considération est le plus petit rayon R5 que présente la surface de raccordement 5 dans le plan longitudinal L1 qui contient la direction axiale XX' et qui est perpendiculaire à la direction transversale ZZ'.The first parameter to take into consideration is the smaller radius R5 than the connection surface 5 in the longitudinal plane L1 which contains the direction axial XX 'and which is perpendicular to the transverse direction ZZ '.

    Le second paramètre à prendre en considération est la circonférence C1 que présente la jupe dans un plan transversal T perpendiculaire à la direction axiale XX' et situé à mi-distance entre les extrémités 121, 122 du tube.The second parameter to consider is the C1 circumference presented by the skirt in a transverse plane T perpendicular to the axial direction XX 'and located midway between the ends 121, 122 of the tube.

    Par hypothèse, la jupe 1 présente par ailleurs, dans tout plan transversal parallèle au plan T, une épaisseur locale à la fois sensiblement constante et égale ou très voisine de l'épaisseur moyenne E2 que présente cette jupe sur toute sa longueur le long de l'axe XX'.By assumption, the skirt 1 also presents, in any transverse plane parallel to the plane T, a thickness local both substantially constant and equal or very close to the average thickness E2 that this skirt has along its entire length along the axis XX '.

    Selon son aspect fondamental, l'invention prévoit ainsi de donner au rapport C1/R5 de la circonférence C1 au rayon minimal R5 une valeur inférieure à 20 (c'est-à-dire moins de 6. π), et éventuellement au plus égal à dix (c'est-à-dire à peine plus de 3. π).According to its fundamental aspect, the invention thus provides to give the C1 / R5 ratio of the circumference C1 to the minimum radius R5 a value less than 20 (i.e. less than 6. π), and possibly at most equal to ten (i.e. just over 3. π).

    Selon un autre aspect de l'invention, le confort de pression en fin d'utilisation du tube peut être amélioré en donnant à la jupe 1 et à l'encolure 4 des épaisseurs moyennes identiques ou très voisines, ou au moins en donnant au rapport de l'épaisseur moyenne de l'encolure à l'épaisseur moyenne de la jupe une valeur au plus égale à 2.According to another aspect of the invention, the comfort of pressure at the end of use of the tube can be improved by giving the skirt 1 and the neck 4 medium thicknesses identical or very similar, or at least by giving the ratio of the average thickness of the neck to the thickness average of the skirt a value at most equal to 2.

    Dans la mesure où l'épaisseur du tube conforme à l'invention doit, en particulier au niveau de l'encolure, être assez faible pour assurer une grande souplesse de la tête et peut par conséquent devenir insuffisante pour assurer l'étanchéité du tube vis-à-vis de l'air, et plus précisément de l'oxygène contenue dans l'air, et préserver le contenu du tube, il peut être conseillé de recouvrir le tube d'un vernis barrière pratiquement sur toute sa surface externe y compris la tête 2, le canal de distribution 3 pouvant cependant en être dispensé dans la mesure notamment où il peut sans inconvénient présenter une plus grande épaisseur.Insofar as the thickness of the tube conforms to the invention must, in particular at the neck, be weak enough to provide great flexibility of the head and may therefore become insufficient to ensure the airtightness of the tube, and more precisely oxygen contained in the air, and preserve the contents of the tube, it may be advisable to cover the tube of barrier varnish practically over its entire surface external including head 2, distribution channel 3 can however be exempted to the extent in particular where it can safely present greater thickness.

    Comme cependant le tube conforme à l'invention peut prendre une forme relativement complexe, d'ailleurs susceptible de viser un résultat esthétique particulier, il est préférable de déposer ce vernis barrière par projection, et non pas par le passage d'un rouleau comme cela est généralement pratiqué dans l'art antérieur.As, however, the tube according to the invention can take a relatively complex form, moreover susceptible to aim for a particular aesthetic result it is better to deposit this barrier varnish by spraying, and not by the passage of a roller as is generally practiced in the prior art.

    L'invention s'applique de façon privilégiée à la réalisation de tubes dont la jupe 1 et la tête 2 sont formées d'une seule pièce par injection d'un matériau thermoplastique élastiquement étirable dans son plan d'au moins cinq pour cent de préférence, et éventuellement de plus de dix pour cent.The invention applies in a privileged manner to the production of tubes whose skirt 1 and head 2 are formed in one piece by injection of a thermoplastic material elastically stretchable in its plane of at least five percent preferably, and possibly more than ten percent.

    Ainsi que le montre la figure 6, la jupe peut alors être définie par une génératrice G non parallèle à la direction axiale XX', la forme du tube étant ainsi plus libre que dans l'art antérieur.As shown in Figure 6, the skirt can then be defined by a generator G not parallel to the direction axial XX ', the shape of the tube thus being freer than in the prior art.
