Abstract

The present invention relates to a flexible package for storing and dispensing liquid or pasty matters, of the type made by moulding a plastics material and comprising a tube extended by an endpiece, the joining portion of these two parts being such as to allow the complete expulsion of the product, wherein the joining portion is deformed irreversibly under the action exerted thereon by the user.

Description

La présente invention est relative à des perfectionnements apportés aux emballages souples à système d'expulsion de leur contenu, du genre comportant un tube prolongé par un embout ou une canule. De tels dispositifs sont généralement utilisés pour injecter des produits liquides ou pâteux dans le corps humain ou dans celui d'un animal.The present invention relates to improvements made to flexible packaging with expulsion system for their content, of the type comprising a tube extended by a nozzle or a cannula. Such devices are generally used to inject liquid or pasty products into the human body or that of an animal.

On connaît des dispositifs du genre en question fabriqués soit d'une seule pièce, soit en deux parties et qui contiennent la dose exacte de produit nécessaire à une application.Devices of the type in question are known, manufactured either in one piece or in two parts and which contain the exact dose of product necessary for an application.

Les premiers sont généralement réalisés en plastisol, c'est-à-dire obtenus à la manière connue par moulage autour d'un mandrin chauffé qu'on trempe dans un bain de cette matière.The first are generally made of plastisol, that is to say obtained in the known manner by molding around a heated mandrel which is dipped in a bath of this material.

Les seconds consistent en un tube extrudé ouvert à ses deux extrémités, dont l'une est soudée à la base d'un embout ou canule tandis que l'autre est fermée par pincement une fois que le produit actif a été placé dans le tube.The second consist of an extruded tube open at its two ends, one of which is welded to the base of a tip or cannula while the other is closed by pinching once the active product has been placed in the tube.

Tous ces dispositifs comportent une jonction entre le tube et la canule qui constitue un épaulement offrant une résistance à l'écrasement supérieure à celle du reste du tube.All these devices comprise a junction between the tube and the cannula which constitutes a shoulder offering a resistance to crushing greater than that of the rest of the tube.

En ce qui concerne les dispositifs réalisés en deux éléments ils nécessitent deux opérations de fabrication de sorte qu'ils ne sont pas économiques. Ce mode de fabrication entraîne également un surcroît de matière au niveau de la jonction des deux éléments dont le coût grève encore plus leur prix de revient.Regarding the devices made in two elements, they require two manufacturing operations so that they are not economical. This manufacturing method also results in additional material at the junction of the two elements, the cost of which increases their cost even more.

De plus, un autre inconvénient des dispositifs réalisés en deux pièces est l'apparition fréquente d'une fuite de produit à la jonction entre le tube et l'embout de sorte qu'un contrôle de tous les lots de fabrication doit être effectué.In addition, another drawback of the devices produced in two pieces is the frequent appearance of a product leak at the junction between the tube and the end piece so that a check of all the manufacturing batches must be carried out.

L'épaulement que l'on rencontre sur tous les dispositifs présente quant à lui un inconvénient majeur dû au fait que toute la matière contenue dans le tube ne peut pas être entièrement expulsée. C'est ainsi que les dispositifs actuellement vendus dans le commerce contiennent environ 30 % de produit actif de plus qu'il ne faut du fait qu'une telle quantité reste au niveau de la jonction du tube et de la canule.The shoulder that is encountered on all devices has a major drawback due to the fact that all the material contained in the tube cannot be entirely expelled. Thus the devices currently sold commercially contain about 30% more active product than is necessary because such an amount remains at the junction of the tube and the cannula.

Enfin en ce qui concerne les tubes en plastisol, ils présentent une souplesse trop importante qui nuit à la bonne rigidité de la canule.Finally, as regards the plastisol tubes, they have too great a flexibility which affects the good rigidity of the cannula.

Les perfectionnements qui font l'objet de la présente invention visent à remédier à ces inconvénients et à permettre la réalisation d'un dispositif du genre en question qui soit d'un prix de revient très bas et évite une perte trop importante de produit actif.The improvements which are the subject of the present invention aim to remedy these drawbacks and to allow the production of a device of the type in question which is of a very low cost price and avoids too great a loss of active product.

A cet effet l'emballage suivant l'invention est fabriqué par injection sous pression d'une matière plastique, la jonction entre le tube et la canule étant réalisée sous la forme en soi connue d'un col à deux courbures inverses et qui comporte des moyens de se déformer complètement de manière irréversible sous l'action exercée sur lui par l'utilisateur pour provoquer son aplatissement complet.To this end, the packaging according to the invention is produced by injection under pressure of a plastic material, the junction between the tube and the cannula being produced in the form known per se of a neck with two reverse curvatures and which comprises means to deform completely irreversibly under the action exerted on it by the user to cause its complete flattening.

On a représenté en fig. 1 un dispositif suivant l'invention comportant essentiellement un emballage souple 1 et un obturateur 2.There is shown in fig. 1 a device according to the invention essentially comprising a flexible packaging 1 and a shutter 2.

L'emballage 1 est réalisé d'une pièce par moulage sous pression d'une matière plastique telle que le polyéthylène ou l'EVA (éthylène-vinyl-acètate). Il comprend une jupe tubulaire à section constante 3 qui se prolonge par une canule 4. Le tube 3 et la canule 4 sont reliés par un col 5 à deux courbures inversées du genre de celui que l'on rencontre sur les bouteilles. L'extrémité libre 4a de la canule est arrondie de manière à ne pas blesser lorsqu'on la met en place, elle comporte une ouverture centrale d'expulsion 4b à diamètre calibré. L'épaisseur de la canule est de l'ordre de 0,7 mm, celle du col 5 allant en diminuant en direction de la jupe 3 de manière à se raccorder à celle-ci dont l'épaisseur est de l'ordre de 0,4 mm. Les rayons du col sont choisis de manière que celui-ci constitue une garde contre un enfoncement intempestif du dispositif. C'est ainsi que dans un mode de réalisation avantageux les rayons de raccordement du col à la canule et à la jupe sont respectivement de 25 et 12 mm. Le bas de la jupe 3 est aminci sur 4 à 5 mm de hauteur pour constituer une zone 3a facilitant la soudure une fois que cette jupe a été aplatie après remplissage du dispositif par le produit actif (fig. 2) en position retournée c'est-à-dire la canule orientée vers le bas et obturée.The packaging 1 is made in one piece by pressure molding of a plastic material such as polyethylene or EVA (ethylene-vinyl acetate). It comprises a tubular skirt with constant section 3 which is extended by a cannula 4. The tube 3 and the cannula 4 are connected by a neck 5 with two inverted curvatures of the kind encountered on the bottles. The free end 4a of the cannula is rounded so as not to hurt when it is put in place, it has a central expulsion opening 4b with calibrated diameter. The thickness of the cannula is of the order of 0.7 mm, that of the neck 5 decreasing in the direction of the skirt 3 so as to be connected to the latter whose thickness is of the order of 0 , 4 mm. The radii of the neck are chosen so that it constitutes a guard against untimely sinking of the device. Thus, in an advantageous embodiment, the radii for connecting the neck to the cannula and to the skirt are 25 and 12 mm respectively. The bottom of the skirt 3 is thinned to 4 to 5 mm in height to form a zone 3a facilitating the welding once this skirt has been flattened after filling of the device with the active product (fig. 2) in the inverted position. that is, the cannula oriented downwards and closed.

L'obturateur 2 est réalisé sous la forme d'un capuchon 2a à fond arrondi dont le diamètre intérieur est déterminé de manière à s'engager librement sur l'extrémité de la canule. Le fond de l'obturateur comporte un téton intérieur 2b dont le diamètre est déterminé de manière que ce téton pénètre à force dans l'ouverture 4b de la canule 4. Le téton peut comporter des cordons périphériques non représentés, propres à augmenter la force de retenue de l'obturateur par rapport à l'ouverture précitée.The obturator 2 is produced in the form of a cap 2a with a rounded bottom, the internal diameter of which is determined so as to engage freely on the end of the cannula. The bottom of the shutter has an internal stud 2b, the diameter of which is determined so that this stud penetrates by force in the opening 4b of the cannula 4. The stud may include peripheral cords, not shown, capable of increasing the retaining force of the obturator relative to the abovementioned opening.

Une fois le dispositif rempli de produit actif il se présente en section transversale comme représenté en fig.3, c'est-à-dire que le bas de sa jupe constitue un bord rectiligne 3b déterminé par la soudure de la zone 3a après son aplatissement. La présence du bord 3b entraîne la déformation de toute la jupe 3 qui forme alors juste avant le col 5 deux renflements symétriques 3c, 3d. On note que l'emballage 1 présente avantageusement un volume correspondant à la dose exacte de produit actif qui doit être utilisée pour une application. Par exemple cet emballage 1 contient la dose exacte d'un micro-lavement se présentant sous forme de gel.Once the device is filled with active product, it has a cross-section as shown in FIG. 3, that is to say that the bottom of its skirt constitutes a straight edge 3b determined by the welding of the zone 3a after its flattening. . The presence of the edge 3b causes the deformation of the entire skirt 3 which then forms just before the neck 5 two symmetrical bulges 3c, 3d. It should be noted that the packaging 1 advantageously has a volume corresponding to the exact dose of active product which must be used for an application. For example, this package 1 contains the exact dose of a micro-enema in the form of a gel.

Pour expulser le produit il suffit de disposer l'emballage entre 1∈ pouce et l'index de l'utilisateur comme illustré en fig. 4, ces deux doigts prenant appui respectivement sur les renflements nrécités. Le déplacement du pouce en direction de l'index provoque la déformation du renflement 3c correspondant qu'on peut aisément faire plaquer contre la face intérieure de celui 3d (fig. 5).To expel the product, simply place the packaging between 1∈ inch and the user's index finger as illustrated in fig. 4, these two fingers bearing respectively on the nrécités swellings. The displacement of the thumb in the direction of the index finger causes the deformation of the corresponding bulge 3c which can easily be pressed against the inner face of that 3d (fig. 5).

On choisit pour le polyéthylène servant à la réalisation de l'emballage, une densité ou poids volumique assurant une déformation du renflement 3c assimilé au cloquage, c'est-à-dire qu'à un certain moment ce renflement passe par une position d'équilibre instable et demeure ensuite dans la position concave représentée en fig. 5 sous l'effet de la force initiale exercée dans le sens de la flèche F. On remarque en fig. 6 que le renflement 3c est également complètement en appui contre celui 3d dans le sens transversal.We choose for the polyethylene used to make the packaging, a density or density ensuring a deformation of the bulge 3c assimilated to blistering, that is to say that at a certain moment this bulge passes through a position of unstable equilibrium and then remains in the concave position shown in fig. 5 under the effect of the initial force exerted in the direction of arrow F. We note in fig. 6 that the bulge 3c is also completely in abutment against that 3d in the transverse direction.

Ainsi lors de l'utilisation du dispositif suivant l'invention, on expulse la totalité du produit qu'il renferme, la perte ne représentant que le volume contenu dans la canule.Thus when using the device according to the invention, the entire product is expelled, the loss representing only the volume contained in the cannula.

On notera enfin que la matière plastique utilisée pour l'injection du dispositif suivant l'invention comporte un poids moléculaire assez élevé pour éviter la formation de criques au niveau du bord soudé 3b.Finally, it should be noted that the plastic material used for injecting the device according to the invention has a molecular weight high enough to avoid the formation of cracks at the welded edge 3b.

Il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents. En particulier la canule 4 pourrait être remplacée par un embout de forme quelconque adapté au genre de déversement du produit contenu dans l'emballage.It should moreover be understood that the above description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents. In particular the cannula 4 could be replaced by a nozzle of any shape adapted to the type of spillage of the product contained in the packaging.
