Description
CONDITIONNEMENT A TUBE SOUPLE ET BOUCHON SECABLE . PACKAGING WITH FLEXIBLE TUBE AND DRY CAP.
L'invention concerne, de façon générale, les emballages en forme de tubes, traditionnellement utilisés pour le conditionnement de produits tels que dentifrices, crèmes alimentaires, produits cosmétiques, etc. The invention relates, in general, tube-shaped packaging, traditionally used for packaging products such as toothpastes, creams, cosmetics, etc.
Plus précisément, l'invention concerne un conditionnement pour produit pâteux, visqueux ou crémeux, réalisé d'une seule pièce et comprenant un tube, un bouchon, et une zone sécable, le tube étant doté d'une jupe souple s 'étendant autour et le long d'un axe longitudinal, et d'une tête percée d'un canal axial, la zone sécable entourant le canal axial et reliant la tête au bouchon, le bouchon étant disposé en position retournée et obturant le canal axial, ce canal servant d'orifice d'évacuation après rupture de la zone sécable, le bouchon et la tête présentant des surfaces externes respectives mutuellement en vis-à-vis et respectivement concave et convexe, et la zone sécable s 'étendant intégralement dans un premier demi-espace délimité par un plan perpendiculaire à l'axe et contenant le bouchon. More specifically, the invention relates to a package for pasty product, viscous or creamy, made in one piece and comprising a tube, a plug, and a breakable zone, the tube being provided with a flexible skirt extending around and along a longitudinal axis, and a head pierced with an axial channel, the breakable zone surrounding the axial channel and connecting the head to the plug, the plug being disposed in the inverted position and closing the axial channel, this channel serving discharge port after rupture of the breakable zone, the cap and the head having respective mutually facing and respectively concave and convex external surfaces, and the breakable zone extending integrally in a first half-space delimited by a plane perpendicular to the axis and containing the cap.
Un tel conditionnement est par exemple décrit dans le brevet français FR 2 031 040. Such a packaging is described, for example, in French patent FR 2 031 040.
Des conditionnements au moins similaires sont fabriqués en grande série, notamment pour contenir des échantillons gratuits de produits cosmétiques. At least similar packages are manufactured in large series, especially to contain free samples of cosmetics.
En dépit de leur caractère relativement éphémère, ces conditionnements doivent respecter diverses exigences antinomiques, et notamment répondre à la double nécessité de n'entraîner qu'un très faible coût de fabrication et de respecter des normes de qualité qui fassent honneur aux produits qu'ils contiennent. In spite of their relatively ephemeral nature, these packaging must meet various contradictory requirements, and in particular meet the dual need to cause only a very low manufacturing cost and to respect quality standards that do honor to the products they contain.
Or, le maintien du bouchon sur le tube au moyen d'une zone sécable, donc fragile, pose le problème de l'intégrité du conditionnement en toutes circonstances. En particulier, l'avantage qu'offre un conditionnement de ce type, pour ce qui concerne l'automatisation de sa fabrication, est contrebalancé par le risque important qu'il occasionne des fuites intempestives, résultant par exemple de la rupture de la zone sécable dans le sac à main d'une utilisatrice. However, maintaining the cap on the tube by means of a breakable zone, so fragile, poses the problem of the integrity of the packaging in all circumstances. In particular, the advantage offered by a packaging of this type, as regards the automation of its manufacture, is counterbalanced by the significant risk that it causes untimely leaks, resulting for example from breaking the breakable area. in the handbag of a user.
Dans ce contexte, l'invention a pour but de proposer un conditionnement dont la structure soit adaptée à un usage de courte durée sans pour autant soulever les problèmes précédemment mentionnés ni obliger leurs utilisateurs à consommer en une seule fois le produit conditionné en les privant de la possibilité de reboucher ce conditionnement. In this context, the invention aims to provide a packaging whose structure is adapted to a short-term use without raising the aforementioned problems or require their users to consume at one time the packaged product by depriving them of the possibility of filling this packaging.
A cette fin, le conditionnement de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce qu'il est réalisé en polyoléfine et en ce que, dans chacun des plans axiaux d'un ensemble d'au moins trois plans axiaux régulièrement répartis autour de l'axe, les surfaces externes du bouchon et de la tête présentent deux points respectifs correspondants dont la distance angulaire, mesurée par un angle couvrant au moins partiellement la zone sécable et dont le sommet appartient à l'axe, est au plus égale à 20 degrés. For this purpose, the packaging of the invention, moreover in accordance with the generic definition given in the preamble above, is essentially characterized in that it is made of polyolefin and in that in each of the axial planes of an assembly of at least three axial planes regularly distributed about the axis, the external surfaces of the plug and the head have two corresponding respective points whose angular distance, measured by an angle at least partially covering the breakable zone and whose vertex belongs to the axis, is at most equal to 20 degrees.
Deux points appartenant respectivement au bouchon et à la tête seront ici considérés comme correspondants dès lors qu'ils sont situés sur un même cercle centré sur le point de pivotement virtuel du bouchon par rapport à la tête, ces points pouvant donc venir en contact l'un avec l'autre si l'effort appliqué entre le bouchon et la tête pour obtenir ce pivotement est suffisant pour conduire à ce contact. Two points belonging respectively to the cap and to the head will here be considered as corresponding since they are located on the same circle centered on the virtual pivot point of the cap relative to the head, these points can therefore come into contact with the with the other if the force applied between the cap and the head to obtain this pivoting is sufficient to lead to this contact.
Il est par ailleurs judicieux de prévoir que, dans chacun des plans axiaux précités et dans une zone radialement interne aux deux points correspondants, la surface externe du bouchon fasse avec un plan perpendiculaire à l'axe longitudinal un angle de contredépouille au moins égal à 5 degrés. It is also wise to provide that, in each of the aforementioned axial planes and in a radially internal zone at the two corresponding points, the outer surface of the plug makes with a plane perpendicular to the longitudinal axis an offset angle at least equal to 5 degrees.
En outre, dans chacun de ces mêmes plans axiaux et dans la zone radialement interne aux deux points correspondants, les surfaces externes du bouchon et de la tête font entre elles un angle de préférence au plus égal à 10 degrés. In addition, in each of these same axial planes and in the radially inner zone at the two corresponding points, the external surfaces of the plug and the head are between them preferably at most 10 degrees.
De manière avantageuse, la surface externe du bouchon s'étend, à distance de l'axe, jusqu'à un bord au moins partiellement contenu dans le plan délimitant le premier demi-espace et définissant, dans ce plan, un polygone de sustentation pour le conditionnement une fois placé dans une configuration opérationnelle rebouchée après rupture de la zone sécable . Advantageously, the outer surface of the cap extends, at a distance from the axis, to an edge at least partially contained in the plane delimiting the first half-space and defining, in this plane, a lifting polygon for the package once placed in an operational configuration closed after rupture of the breakable zone.
II est également souhaitable de prévoir qu'une partie de la surface externe de la tête appartienne au premier demi-espace. It is also desirable to provide that part of the outer surface of the head belongs to the first half-space.
Le rapport minimal du rayon de la partie de la surface externe de la tête appartenant au premier demi- espace au rayon de la face interne de la paroi latérale du bouchon peut alors être au moins égal à 0.5, ou même être au moins égal à 0.7. The minimum ratio of the radius of the part of the external surface of the head belonging to the first half space to the radius of the internal face of the side wall of the plug can then be at least 0.5, or even at least 0.7 .
Dans le mode de réalisation le plus simple du conditionnement de l'invention, les surfaces externes du bouchon et de la tête présentent une symétrie de révolution autour de l'axe longitudinal. In the simplest embodiment of the packaging of the invention, the outer surfaces of the plug and the head have a symmetry of revolution about the longitudinal axis.
D'autres caractéristiques et avantages de l'invention ressortiront clairement de la description qui en est faite ci-après, à titre indicatif et nullement limitatif, en référence aux dessins annexés, dans lesquels : Other characteristics and advantages of the invention will emerge clearly from the description which is given hereinafter, by way of indication and in no way limitative, with reference to the appended drawings, in which:

Comme indiqué précédemment, l'invention concerne un conditionnement pour produit pâteux, visqueux ou crémeux, comprenant un tube 1, un bouchon 2, et une zone sécable 3. As indicated above, the invention relates to a packaging for pasty, viscous or creamy product, comprising a tube 1, a stopper 2, and a breakable zone 3.
Ce conditionnement est réalisé d'une seule pièce, par injection d'un matériau thermoplastique appartenant à la classe des polyoléfines . This packaging is made in one piece, by injection of a thermoplastic material belonging to the class of polyolefins.
On sélectionnera de préférence une polyoléfine dans la famille des polypropylènes ou dans la famille des polyéthylènes . A polyolefin in the family of polypropylenes or in the family of polyethylenes will preferably be selected.
On retiendra avantageusement un polypropylène si l'on tient à privilégier la rigidité du bouchon et la tenue de la paroi aux agents tensio-actifs des crèmes conditionnées dans le tube. Polypropylene will advantageously be retained if one wishes to give preference to the rigidity of the plug and the resistance of the wall to the surface-active agents of the creams packaged in the tube.
En revanche, on retiendra plutôt un polyéthylène, et plus préférablement un polyéthylène linéaire ou un polyéthylène haute densité, si l'on tient à privilégier les propriétés barrières de la paroi du tube, et notamment les propriétés de barrière à la vapeur d'eau. On the other hand, a polyethylene, and more preferably a linear polyethylene or a high density polyethylene, will be retained, if one wishes to favor the barrier properties of the wall of the tube, and in particular the properties of barrier to water vapor.
Le tube 1 est principalement formé d'une jupe souple 11 et d'une tête 12, la jupe s 'étendant autour et le long d'un axe longitudinal Z. La jupe souple 11 présente, à l'opposé de la tête 12, une extrémité de remplissage 111 initialement ouverte . The tube 1 is mainly formed of a flexible skirt 11 and a head 12, the skirt extending around and along a longitudinal axis Z. The flexible skirt 11 has, opposite the head 12, a filling end 111 initially open.
Le produit destiné à être distribué par le tube 1 est introduit dans ce tube à travers l'extrémité de remplissage 111 qui, une fois le tube rempli, est refermée par écrasement et auto-soudure à chaud. The product intended to be distributed by the tube 1 is introduced into this tube through the filling end 111 which, once the filled tube, is closed by crushing and self-welding hot.
La tête 12 est percée d'un canal axial 120 au moins partiellement entouré par la zone sécable 3. The head 12 is pierced with an axial channel 120 at least partially surrounded by the breakable zone 3.
La rupture de la zone sécable place le conditionnement dans sa configuration opérationnelle, et permet au canal axial 120 de remplir la fonction d'orifice d'évacuation du produit contenu dans le tube. The rupture of the breakable zone places the packaging in its operational configuration, and allows the axial channel 120 to fulfill the function of discharge orifice of the product contained in the tube.
Dans la configuration originelle du conditionnement, qui est celle qu'illustrent les figures, la zone sécable 3 relie la tête 12 au bouchon 2, le bouchon 2 étant alors disposé en position retournée et obturant le canal axial 120. In the original configuration of the packaging, which is that shown in the figures, the breakable zone 3 connects the head 12 to the plug 2, the plug 2 then being arranged in the inverted position and closing the axial channel 120.
Dans cette configuration originelle, le bouchon 2 et la tête 12 présentent des surfaces externes respectives, 21 et 121, mutuellement en vis-à-vis. In this original configuration, the cap 2 and the head 12 have respective external surfaces, 21 and 121, mutually facing each other.
La surface externe 21 du bouchon 20 est concave, tandis que la surface externe 121 de la tête 12 est convexe . The outer surface 21 of the cap 20 is concave, while the outer surface 121 of the head 12 is convex.
Chacune de ces surfaces 21 et 121 entoure totalement l'axe longitudinal Z. En d'autres termes, tout plan passant par l'axe Z contient nécessairement des points de chacune des surfaces 21 et 121. Each of these surfaces 21 and 121 completely surrounds the longitudinal axis Z. In other words, any plane passing through the Z axis necessarily contains points of each of the surfaces 21 and 121.
Toutefois, alors que la surface externe 121 de la tête 12 doit être d'un seul tenant pour assurer l'étanchéité du tube 1, la surface externe 21 du bouchon 20 peut éventuellement être ajourée localement. However, while the outer surface 121 of the head 12 must be in one piece to seal the tube 1, the outer surface 21 of the cap 20 may optionally be perforated locally.
Par ailleurs, la zone sécable 3 s'étend intégralement dans un premier demi-espace qui est délimité par un plan E perpendiculaire à l'axe Z et qui contient le bouchon 2. Moreover, the breakable zone 3 extends integrally in a first half-space which is delimited by a plane E perpendicular to the Z axis and which contains the cap 2.
Comme le montrent les figures, les surfaces externes 21 et 121 du bouchon 2 et de la tête 12 peuvent présenter une symétrie de révolution autour de l'axe longitudinal Z . As shown in the figures, the outer surfaces 21 and 121 of the plug 2 and the head 12 may have a symmetry of revolution about the longitudinal axis Z.
Un conditionnement tel que décrit jusqu'à présent est notamment connu par le brevet français FR 2 031 040. A packaging as described up to now is known in particular by the French patent FR 2 031 040.
Outre sa surface externe 21, le bouchon 2 présente une paroi latérale 22 qui sert de moyen de préhension de ce bouchon 2, et qui se raccorde à la surface externe 21 au bord 20 de cette surface externe. In addition to its outer surface 21, the plug 2 has a side wall 22 which serves as a gripping means of the plug 2, and which is connected to the outer surface 21 at the edge 20 of this outer surface.
Le bouchon 2 peut aussi comprendre, de façon optionnelle, un ergot central 23 se raccordant à la surface externe 21 et entouré par la paroi latérale 22. The cap 2 may also optionally comprise a central pin 23 connected to the outer surface 21 and surrounded by the lateral wall 22.
Dans la configuration originelle du conditionnement qu'illustrent les figures, l'ergot 23 du bouchon 2 pointe suivant l'axe longitudinal Z en étant tourné à l'opposé du tube 1. In the original configuration of the packaging shown in the figures, the lug 23 of the cap 2 points along the longitudinal axis Z while being turned away from the tube 1.
La rupture de la zone sécable 3 permet de placer ce conditionnement dans une configuration opérationnelle en séparant le bouchon 2 du tube 1, ce qui provoque l'ouverture du canal 120 formant l'orifice d'évacuation. The rupture of the breakable zone 3 makes it possible to place this packaging in an operational configuration by separating the plug 2 from the tube 1, which causes the opening of the channel 120 forming the discharge orifice.
Ce conditionnement peut ensuite être placé dans une configuration opérationnelle fermée en retournant le bouchon et en insérant l'ergot 23 dans le canal axial 120 afin d'assurer l'étanchéité du tube 1 et prévenir toute fuite du produit qu'il contient après rebouchage. This packaging can then be placed in a closed operational configuration by inverting the plug and inserting the lug 23 into the axial channel 120 in order to ensure the sealing of the tube 1 and prevent any leakage of the product it contains after capping.
Des reliefs complémentaires 125 et 235 sont de préférence prévus respectivement sur la tête 12 en bordure du canal axial 120 et sur l'ergot 23 pour faciliter, en configuration opérationnelle fermée du conditionnement, le maintien de cet ergot 23 dans ce canal axial 120. Complementary reliefs 125 and 235 are preferably respectively provided on the head 12 at the edge of the axial channel 120 and on the lug 23 to facilitate, in the closed operational configuration of the packaging, maintaining this lug 23 in this axial channel 120.
En variante, ou de façon cumulative, des reliefs complémentaires 225 et 115 peuvent être prévus respectivement sur la face interne 222 de la paroi latérale 22 du bouchon 2 et sur la partie de la jupe 11 qui est adjacente à la tête 12 pour faciliter le maintien de l'ergot 23 dans le canal axial 120 dans la configuration opérationnelle du conditionnement. Alternatively, or cumulatively, complementary reliefs 225 and 115 may be provided respectively on the inner face 222 of the side wall 22 of the cap 2 and the portion of the skirt 11 which is adjacent to the head 12 to facilitate the holding of the lug 23 in the axial channel 120 in the operational configuration of the package.
Néanmoins, il est tout à fait possible, comme décrit dans le brevet français FR 2 031 040 précité, de prévoir d'autres moyens pour assurer le maintien du bouchon 2 sur la tête 12 dans la configuration opérationnelle fermée du conditionnement, et notamment des filets de vis complémentaires sur le bouchon et sur la tête. Nevertheless, it is quite possible, as described in the French patent FR 2 031 040 cited above, to provide other means to ensure the maintenance of the cap 2 on the head 12 in the closed operational configuration of the packaging, and in particular nets additional screws on the cap and on the head.
L'un des objectifs visés par l'invention est de réduire de façon considérable le risque de rupture intempestive de la zone sécable 3 dans la configuration originelle du conditionnement. One of the objectives of the invention is to significantly reduce the risk of inadvertent rupture of the breakable zone 3 in the original configuration of the packaging.
Pour ce faire, les surfaces externes 21 et 121 du bouchon 2 et de la tête 12 présentent, dans chacun des plans axiaux d'un ensemble d'au moins trois plans axiaux régulièrement répartis autour de l'axe Z, deux points respectifs PI et P2 qui sont à la fois éventuellement susceptibles de venir en contact l'un avec l'autre et suffisamment proches l'un de l'autre pour que ce contact éventuel intervienne après une déformation non destructive du conditionnement. To do this, the outer surfaces 21 and 121 of the plug 2 and the head 12 have, in each of the axial planes of an assembly of at least three axial planes regularly distributed around the Z axis, two respective points PI and P2 which are both possibly able to come into contact with each other and sufficiently close to each other for this eventual contact to occur after non-destructive deformation of the packaging.
De façon plus rigoureuse, les points PI et P2, qui seront ici désignés comme des points correspondants, sont des points qui appartiennent respectivement au bouchon 2 et à la tête 1, qui appartiennent en outre à l'un des plans axiaux d'un ensemble d'au moins trois plans axiaux, par exemple au plan de la figure 4 ou à l'un des deux autres plans passant par l'axe Z et disposés à 120 degrés du plan de la figure 4, et qui sont situés sur un même cercle centré sur le point de pivotement virtuel du bouchon 2 par rapport à la tête 12, lorsqu'un effort transversal est appliqué entre le bouchon et la tête. Par ailleurs, les points correspondants PI et P2 seront considérés comme suffisamment proches l'un de l'autre à condition que leur distance angulaire, mesurée par un angle Al couvrant au moins partiellement la zone sécable 3 et dont le sommet appartient à l'axe Z, soit au plus égale à 20 degrés. More strictly, the points PI and P2, which will here be designated as corresponding points, are points belonging respectively to the plug 2 and the head 1, which belong in addition to one of the axial planes of a set. at least three axial planes, for example in the plane of Figure 4 or one of the two other planes passing through the Z axis and arranged at 120 degrees from the plane of Figure 4, and which are located on the same circle centered on the virtual pivot point of the plug 2 relative to the head 12, when a transverse force is applied between the plug and the head. Moreover, the corresponding points PI and P2 will be considered sufficiently close to each other provided that their angular distance, measured by an angle A1 at least partially covering the breakable zone 3 and whose vertex belongs to the axis Z, at most equal to 20 degrees.
Plus avantageusement encore, l'angle Al peut être au plus égal à 15 degrés. More preferably, the angle Al can be at most equal to 15 degrees.
En effet les polymères utilisés pour fabriquer le tube de l'invention sont caractérisés par un coefficient d'élongation à la rupture, mesuré en pourcentage de la longueur de la zone étirée avant élongation (norme ISO 527) . Indeed the polymers used to manufacture the tube of the invention are characterized by a coefficient of elongation at break, measured as a percentage of the length of the stretched zone before elongation (ISO 527).
Ce coefficient d'élongation varie dans des proportions importantes -de 1 à 3- pour certains polyéthylènes . This coefficient of elongation varies in significant proportions - from 1 to 3 for some polyethylenes.
Selon le coefficient d'élongation à la rupture du polymère retenue, et selon la géométrie de la zone sécable, on retiendra un angle Al au plus égal à 20 degrés ou de préférence au plus égal à 15 degrés. According to the coefficient of elongation at break of the selected polymer, and according to the geometry of the breakable zone, an angle Al at most equal to 20 degrees or preferably at most equal to 15 degrees will be retained.
Dans chacun des plans axiaux précités, et dans une zone radialement interne aux deux points correspondants PI et P2, la surface externe 21 du bouchon 2 fait avec un plan perpendiculaire à l'axe longitudinal Z un angle de contredépouille Ad de préférence au moins égal à 5 degrés, ou même au moins égal à 10 degrés. In each of the aforesaid axial planes, and in an area radially internal to the two corresponding points P1 and P2, the outer surface 21 of the plug 2 is made with a plane perpendicular to the longitudinal axis Z with an angle of understep Ad preferably at least equal to 5 degrees, or even at least 10 degrees.
De façon également avantageuse, les surfaces externes respectives, 21 et 121, du bouchon 2 et de la tête 12 font entre elles un angle A2 au plus égal à 10 degrés dans chacun des plans axiaux précités et dans la zone radialement interne aux points correspondants PI et P2. Also advantageously, the respective external surfaces, 21 and 121, of the plug 2 and of the head 12 form between them an angle A2 at most equal to 10 degrees in each of the aforementioned axial planes and in the radially internal zone at the corresponding points PI and P2.
Par ailleurs, il est possible de prévoir que, dans chacun des plans axiaux précités, et dans la zone radialement interne aux deux points correspondants PI et P2, la surface externe 121 de la tête 12 fasse, avec l'axe longitudinal Z, un angle A3 au moins égal à 60 degrés . Moreover, it is possible to provide that, in each of the aforementioned axial planes, and in the region radially internal to the two corresponding points P1 and P2, the external surface 121 of the head 12, with the longitudinal axis Z, an angle A3 at least equal to 60 degrees.
Le bord 20 de la surface externe 21 du bouchon 2 est au moins partiellement contenu dans le plan E qui délimite le premier demi-espace. The edge 20 of the outer surface 21 of the cap 2 is at least partially contained in the plane E which delimits the first half-space.
De plus, le bord 20 définit de préférence, dans ce plan E, un polygone de sustentation pour le conditionnement une fois placé dans sa configuration opérationnelle après rebouchage du bouchon sur le tube. In addition, the edge 20 preferably defines, in this plane E, a lift polygon for conditioning once placed in its operational configuration after plugging the cap on the tube.
En d'autres termes, le conditionnement peut alors reposer sur son bouchon, en position verticale retournée. In other words, the packaging can then rest on its cap, in the vertical position returned.
Pour réduire l'angle Al tout en dotant le conditionnement d'une stabilité satisfaisante en position retournée, il est souhaitable que la surface externe 121 de la tête 12 appartienne elle-même, au moins pour partie, au premier demi-espace délimité par le plan E. To reduce the angle A1 while providing the conditioning a satisfactory stability in the inverted position, it is desirable that the outer surface 121 of the head 12 itself belongs, at least in part, to the first half-space delimited by the plane.
Par exemple, il est avantageux de prévoir que la valeur minimale du rapport R1/R2, défini comme le rapport du rayon RI de la partie de la surface externe 121 de la tête 12 qui appartient au premier demi-espace, au rayon R2 de la face interne 222 de la paroi latérale 22 du bouchon 2, soit au moins égale à 0.5. For example, it is advantageous to provide that the minimum value of the ratio R1 / R2, defined as the ratio of the radius R1 of the portion of the outer surface 121 of the head 12 which belongs to the first half-space, to the radius R2 of the internal face 222 of the side wall 22 of the plug 2, at least equal to 0.5.
Plus avantageusement encore, la valeur minimale du rapport R1/R2 peut être au moins égale à 0.7. More preferably, the minimum value of the ratio R1 / R2 may be at least 0.7.
De préférence, la paroi du bouchon 2 est relativement flexible à l'extérieur de la zone sécable 3 et dans la zone radialement interne aux deux points PI et P2. Preferably, the wall of the plug 2 is relatively flexible outside the breakable zone 3 and in the radially inner zone at the two points P1 and P2.
A cette fin, la paroi du bouchon 2 dans cette zone présente par exemple une épaisseur au plus égale à o, 6 mm. For this purpose, the wall of the plug 2 in this zone has for example a thickness at most equal to 0.6 mm.
