Description

PROCEDE D'OUVERTURE D'UN RECEPTACLE A EMBOUT CASSABLE ET RECEPTACLE LE METTANT EN OEUVRE METHOD OF OPENING A RECEPTACLE WITH BREAKABLE END AND RECEPTACLE USING THE SAME
L'invention concerne un procédé d'ouverture d'un réceptacle tel qu'une cartouche par exemple pour la distribution d'un produit liquide, visqueux ou pâteux tel • que du mastic, au travers d'une canule venant se rapporter sur l'embout du réceptacle initialement obturé avant utilisation et perforé par la suite, pour la distribution du produit. L'invention concerne également des réceptacles à embout particulier mettant en œuvre ce procédé d' ouverture . Chacun connaît des produits liquides, visqueux ou pâteux contenus dans des tubes ou des cartouches en matériau plastique destinés à être utilisés avec une canule d'application venant se ficher sur un embout initialement obturé afin d'assurer une parfaite étanchéité au tube ou à la cartouche avant son utilisation et pendant son stockage. Il reste ensuite à l'utilisateur à ouvrir l'embout du tube ou de la cartouche puis à disposer sur cet embout une canule adaptée à l'application particulière envisagée. La difficulté réside alors dans l'ouverture de l'embout et pour cela il est souvent obligatoire de se munir d'un outil coupant ou perforant qu'on n'a pas toujours sous la main.The invention relates to a method of opening a receptacle such as a cartridge for example for the distribution of a liquid, viscous or pasty product such as • putty, through a cannula coming to bear on the tip of the receptacle initially closed before use and subsequently perforated, for dispensing the product. The invention also relates to receptacles with a particular tip implementing this opening method. Everyone knows of liquid, viscous or pasty products contained in plastic tubes or cartridges intended to be used with an application cannula which is plugged in on a nozzle initially closed in order to ensure perfect sealing of the tube or cartridge. before use and during storage. It then remains for the user to open the end of the tube or of the cartridge and then to place on this end a cannula adapted to the particular application envisaged. The difficulty then resides in the opening of the endpiece and for this it is often compulsory to have a cutting or perforating tool which is not always on hand.
On connaît déjà des solutions pour l'ouverture d'embouts formant aussi canule comme il est par exemple décrit dans les brevets US 4.408.699 et US 2001/9754 prévoyant l'un et l'autre l'ouverture de l'extrémité de la canule par arrachement d'une pièce d'extrémité suivant une ligne de rupture, cette pièce pouvant alors être utilisée comme coiffe de la canule après ouverture. S' agissant de canules rapportées, une solution de ce type est aussi décrite dans le brevet américain US 5.560.521 où le culot de la canule est conformé pour venir se fixer sur l'extrémité de la cartouche tout en la perforant afin de créer une voie de passage pour le produit. La complexité technique de cette solution la rend quasi inapplicable dans les applications où le coût du réceptacle doit être largement abaissé compte tenu des produits à distribuer.Solutions are already known for the opening of end pieces also forming a cannula as is for example described in US Patents 4,408,699 and US 2001/9754 both providing for the opening of the end of the cannula by tearing off an end piece along a rupture line, this piece can then be used as a cap of the cannula after opening. As regards attached cannulas, a solution of this type is also described in US Patent US 5,560,521 where the base of the cannula is shaped to be fixed on the end of the cartridge while perforating it in order to create a passageway for the product. The technical complexity of this solution makes it almost inapplicable in applications where the cost of the receptacle must be greatly lowered given the products to be distributed.
Pour palier l'ensemble de tous ces inconvénients liés à la complexité des solutions voire à leur encombrement lorsque l'embout faisant office de canule allonge le réceptacle, il est maintenant proposé une solution particulièrement avantageuse tant en raison de ce qu'elle procède d'une canule séparable, utilisable comme outil d'ouverture du réceptacle auquel elle se solidarise par des moyens très simples venant directement de l'injection du réceptacle.To overcome all of these drawbacks related to the complexity of the solutions or even their size when the nozzle acting as a cannula lengthens the receptacle, a particularly advantageous solution is now proposed, both because it proceeds from a separable cannula, usable as a tool for opening the receptacle to which it is secured by means very simple coming directly from the injection of the receptacle.
Conformément à l'invention il est à cet effet proposé un procédé d'ouverture d'un réceptacle pour la distribution d'un produit liquide, visqueux ou pâteux au travers d'une canule rapportéeAccording to the invention there is proposed for this purpose a method of opening a receptacle for the distribution of a liquid, viscous or pasty product through an attached cannula.
On comprend bien tout l'intérêt de ce procédé où l'on utilise avantageusement la taille de la canule d'application pour faire levier sur une partie de l'embout solidaire du réceptacle afin de le détacher suivant une ligne de rupture tout en laissant une partie de celui-ci sur laquelle vient finalement s'adapter la canule d'application du produit.We understand all the interest of this process where we advantageously use the size of the application cannula to lever on a part of the end piece integral with the receptacle in order to detach it along a rupture line while leaving a part of it on which the product application cannula is finally fitted.
A cet égard et selon une exécution générale de l'invention il est également prévu un réceptacle avec un embout cassable permettant de solidariser le réceptacle au culot d'une canule de distribution de produit pâteux, visqueux ou liquide, ledit embout étant initialement obturé puis perforé avant utilisation du produit au travers de la canule mettant en œuvre le procédé selon l'invention ; ce réceptacle est remarquable en ce que son embout comporte sur toute sa hauteur des moyens de fixation susceptibles de coopérer avec des moyens correspondant du culot pour la fixation de la canule et à mi-hauteur environ une ligne périphérique d'affaiblissement de l'épaisseur de l'embout et des organes liés à sa partie supérieure pour faciliter l'extraction de cette partie du culot lorsque l'embout est cassé suivant cette ligne d'affaiblissement.In this regard and according to a general embodiment of the invention, there is also provided a receptacle with a breakable tip allowing the receptacle to be fixed to the base of a cannula for dispensing a pasty, viscous or liquid product, said tip being initially closed then perforated. before use of the product through the cannula implementing the method according to the invention; this receptacle is remarkable in that its tip comprises over its entire height fixing means capable of cooperating with corresponding means of the base for fixing the cannula and at mid-height about a peripheral line of weakening of the thickness of the end piece and members linked to its upper part to facilitate the extraction of this part of the base when the end piece is broken along this weakening line.
Naturellement, l'exécution la plus simple à réaliser consiste en un embout cylindrique dont les moyens de fixation à la canule d'application sont constitués d'un filetage à la fois sur la partie externe de l'embout et sur la partie interne du culot de la canule. Dans ces conditions, il suffit de visser la canule sur l'extrémité supérieure de l'embout muni dans sa partie médiane d'une zone de rupture par affaiblissement de son épaisseur, puis par un simple mouvement de bascule sur la. canule, on casse la partie supérieure de l'embout qu'il suffit ensuite d'extraire par des moyens adéquats libérant ainsi le filetage du culot de la canule que l'on vient enfin visser sur la partie inférieure de l'embout fileté restée en place .Naturally, the simplest execution to be carried out consists of a cylindrical end-piece, the means of fixing to the application cannula of which consist of a thread both on the external part of the end-piece and on the internal part of the base. of the cannula. Under these conditions, it suffices to screw the cannula onto the upper end of the nozzle provided in its middle part with a rupture zone by weakening its thickness, then by a simple rocking movement on the. cannula, the upper part of the endpiece is broken, which then suffices to extract by suitable means, thus freeing the threading of the base of the cannula which is finally screwed onto the lower part of the threaded endpiece remaining in square .
D'autres caractéristiques et avantages ressortiront mieux de la description qui va maintenant être donnée d'une exécution préférée d'un réceptacle à embout mettant en œuvre le procédé conforme à l'invention donnée à titre d'exemple non limitatif en référence aux dessins annexésOther characteristics and advantages will emerge more clearly from the description which will now be given of a preferred embodiment of a tip receptacle implementing the method according to the invention given by way of nonlimiting example with reference to the accompanying drawings.
• sur lesquels : • on which:
- la figure 1 est une vue en élévation et en coupe médiane d'un ensemble constitué d'un réceptacle du type d'une cartouche (représentée de manière partielle selon une partie comportant l'embout) et d'une canule d'application montée sur l'embout avant ouverture de l'embout,- Figure 1 is an elevational view in median section of an assembly consisting of a receptacle of the type of a cartridge (shown partially in a part comprising the nozzle) and an application cannula mounted on the nozzle before opening the nozzle,
- la figure 2 représente la même vue que précédemment dans laquelle la partie supérieure de l'embout a été cassée par un mouvement de flexion de la canule d'application,FIG. 2 represents the same view as previously in which the upper part of the end piece was broken by a bending movement of the application cannula,
- la figure 3 représente en élévation et en coupe médiane l'extraction de la partie supérieure de l'embout du culot de la canule d'application, - la figure 4 est une représentation en élévation et en .coupe médiane de la canule vissée sur la partie inférieure de l'embout cassé conformément à la figure 2.- Figure 3 shows in elevation and in median section the extraction of the upper part of the tip of the base of the application cannula, - Figure 4 is a representation in elevation and in .Cut of the cannula screwed on the lower part of the broken end piece according to figure 2.
En références aux figures, le réceptacle 1 est une cartouche en plastique contenant par exemple un produit tel que du mastic ou toute autre produit pâteux ou visqueux ou même liquide, de forme cylindrique pour venir s'insérer dans un distributeur à piston (non représenté sur les figures) destiné à repousser le mastic contenu à l'intérieur de la cartouche 1 afin qu'il soit expulsé vers l'extérieur au travers d'une canule 2 facilitant son application. La canule 2 est traditionnellement de forme allongée comportant à sa base un culot cylindrique 3 muni de moyens de fixation à un embout 4 solidaire de la cartouche 1 ou issu de l'injection de celle-ci ; généralement, la partie distale de la canule 2 est de forme tronconique, ce qui procure classiquement l'avantage de pouvoir ajuster le diamètre de l'ouverture de sortie 5 qui règle l'épaisseur du cordon de produit appliqué.With reference to the figures, the receptacle 1 is a plastic cartridge containing for example a product such as mastic or any other pasty or viscous or even liquid product, of cylindrical shape to be inserted in a piston distributor (not shown in the figures) intended to repel the putty contained inside the cartridge 1 so that it is expelled towards the outside through a cannula 2 facilitating its application. The cannula 2 is traditionally of elongated shape comprising at its base a cylindrical base 3 provided with means for fixing to a nozzle 4 secured to the cartridge 1 or resulting from the injection of the latter; generally, the distal part of the cannula 2 is shaped frustoconical, which conventionally provides the advantage of being able to adjust the diameter of the outlet opening 5 which regulates the thickness of the bead of product applied.
Comme il a déjà été dit dans le préambule, il est en principe nécessaire de perforer l'embout 4 de la cartouche 1 avant le montage d'une canule 2 pour distribuer le produit contenu à l'intérieur. Généralement cette opération nécessite de recourir à un outil tranchant ou perforant ce qui est en général une opération fastidieuse et même dangereuse voire impossible si l'on ne possède pas un outil adapté.As already mentioned in the preamble, it is in principle necessary to perforate the tip 4 of the cartridge 1 before mounting a cannula 2 to dispense the product contained inside. Generally this operation requires the use of a sharp or perforating tool which is generally a tedious and even dangerous operation even impossible if one does not have a suitable tool.
Considérant le fait que la canule 2 qui accompagne la plupart du temps la cartouche 1 pourrait servir d' outil pour pratiquer l'ouverture de l'embout 4, il a été imaginé une fonction nouvelle de levier permettant de casser aisément l'embout 4 en deux parties sensiblement égales suivant une ligne de rupture 6 avantageusement prévue à mi- hauteur dé l'embout 4 ; conformément à la figure 1 l'embout 4 directement issu du moulage de la cartouche 1 et s' étendant à son extrémité supérieure, est de forme cylindrique et comporte de haut en bas un filetage 7 sur sa face extérieure, une toile de fermeture 8 venant obturer l'extrémité supérieure de l'embout 4 empêchant le produit contenu dans la cartouche 1 de s'échapper avant son utilisation.Considering the fact that the cannula 2 which most of the time accompanies the cartridge 1 could serve as a tool for practicing the opening of the end piece 4, a new lever function has been devised making it possible to easily break the end piece 4 into two substantially equal parts along a breaking line 6 advantageously provided at mid-height of the end piece 4; according to Figure 1 the nozzle 4 directly from the molding of the cartridge 1 and extending at its upper end, is of cylindrical shape and comprises from top to bottom a thread 7 on its outer face, a closing cloth 8 coming close the upper end of the nozzle 4 preventing the product contained in the cartridge 1 from escaping before its use.
La ligne de rupture 6 est constituée d'une zone d'affaiblissement de l'épaisseur de la paroi de l'embout 4 s' étendant à peu près à mi-hauteur de l'embout 4 et avantageusement tout autour de celui-ci et en tout cas, sur une distance assurant une cassure totale e la partie supérieure 9 de l'embout 4 lorsque l'on applique une force F de basculement (figure 2) sur la canule 2 créant alors une rupture franche de la ligne d'affaiblissement 6 créant une décapsulation de l'embout 4 comme représenté sur la figure 2 ; la partie inférieure 10 de l'embout 4 ainsi dégagé présente alors une extrémité ouverte 11 de nature à laisser sortir le contenu de la cartouche 1.The rupture line 6 consists of a zone of weakening of the thickness of the wall of the end piece 4 extending roughly halfway up the end piece 4 and advantageously all around the latter and in any case, over a distance ensuring a total break in the upper part 9 of the end piece 4 when a tilting force F is applied (FIG. 2) to the cannula 2, thus creating a clear break in the weakening line 6 creating a decapsulation of the tip 4 as shown in Figure 2; the lower part 10 of the endpiece 4 thus released then has an open end 11 such as to let the contents of the cartridge 1 come out.
Conformément à la figure 3, il reste encore à extraire la partie supérieure 9 de l'embout 4 en la dévissant, comme indiqué en D sur la figure 3, du culot de la canule 2 ; à. cet effet, il est avantageusement prévu de disposer au moins une aile 12 issue de la berge supérieure de la ligne d'affaiblissement 6 c'est-à-dire de la berge située du côté de l'extrémité libre de l'embout lorsqu'il est entier, cette aile s' étendant radialement vers l'extérieur de l'embout 4 pour procurer une prise suffisante pour l'extraction, c'est-à-dire dans le présent exemple, pour le dévissage (flèche d figure 3) de la partie supérieure 9 de l'embout après rupture. Comme représenté enfin sur la figure 4, il suffit alors de visser le culot 3 de la canule 2 qui a été dégagé de la partie supérieure 9 de l'embout, sur la partie inférieure • 10 comportant le même filetage extérieur pour créer une liaison solide entre la cartouche 1 et la canule d'application 2. On observera ici que la ou les ailes 12 facilitant le désengagement de la partie supérieure 9 de l'embout 4 comportant la toile de fermeture 8, constituent avantageusement une butée finale pour le vissage de la canule 2 sur l'extrémité supérieure 9 de l'embout avant ouverture ce qui garantit une rupture de l'embout obligatoirement selon la ligne d'affaiblissement 6. A titre de variante, on pourrait naturellement utiliser tout autre moyen de fixation qu'un filetage pour solidariser dans un premier temps la canule 2 à la partie supérieure 9 de l'embout 4 en vue de le décapsuler ; on pourrait par exemple utiliser un système à rainure ou à baïonnette (non représenté sur les figures) qui serait alors reproduit sur la partie inférieure 10 de l'embout pour réaliser la solidarisation finale de la canule 2 à la cartouche 1 , selon la dernière étape du procédé conforme à l'invention. De même, les ailes 12 facilitant le démontage de la partie supérieure 9 de l'embout, cassé selon la ligne 6, pourraient être remplacées par des éléments venant en relief sur la surface interne du canal de l'embout 4, par exemple une empreinte à 4 ou 6 pans, qui seraient aptes à coopérer avec un outil de forme correspondante, par exemple une clef Allen, pour l'extraction du culot de la canule 2 ; un tel outil (non représenté sur les figures) pourrait être un simple bossage venu de l'injection de la cartouche 1, en saillie sur une partie disponible de la surface de la même cartouche 1, comme par exemple sur la face opposée de celle qui comporte l'embout 4.In accordance with FIG. 3, the upper part 9 of the end piece 4 still has to be extracted by unscrewing it, as indicated in D in FIG. 3, from the base of cannula 2; at. this effect, it is advantageously provided to have at least one wing 12 coming from the upper bank of the weakening line 6, that is to say from the bank situated on the side of the free end of the end piece when it is complete, this wing extending radially outward from the end piece 4 to provide a sufficient grip for the extraction, that is to say in the present example, for unscrewing (arrow d figure 3) of the upper part 9 of the end piece after rupture. As finally shown in FIG. 4, it then suffices to screw the base 3 of the cannula 2 which has been released from the upper part 9 of the end piece, on the lower part • 10 having the same external thread to create a solid connection. between the cartridge 1 and the application cannula 2. It will be observed here that the flange (s) 12 facilitating the disengagement of the upper part 9 of the end piece 4 comprising the closure cloth 8, advantageously constitute a final stop for the screwing of the cannula 2 on the upper end 9 of the endpiece before opening, which guarantees a rupture of the endpiece necessarily along the weakening line 6. As a variant, one could naturally use any other means of fixing than threading for firstly securing the cannula 2 to the upper part 9 of the endpiece 4 in order to decapsulate it; one could for example use a groove or bayonet system (not shown in the figures) which would then be reproduced on the lower part 10 of the nozzle to achieve the final connection of the cannula 2 to the cartridge 1, according to the last step of the process according to the invention. Similarly, the wings 12 facilitating the disassembly of the upper part 9 of the end piece, broken along line 6, could be replaced by elements coming into relief on the internal surface of the channel of the end piece 4, for example an imprint with 4 or 6 sides, which would be able to cooperate with a tool of corresponding shape, for example an Allen key, for the extraction of the base of the cannula 2; such a tool (not shown in the figures) could be a simple boss coming from the injection of the cartridge 1, projecting from an available part of the surface of the same cartridge 1, as for example on the opposite side of that which includes the end piece 4.
De même, on pourrait encore et sans sortir de l'invention, ne prévoir aucune aile extérieure 12 et donner à la partie supérieure 9 de l'embout une longueur lui permettant de dépasser suffisamment hors du culot comportant à cet effet une butée interne en fin de filetage, après cassure selon la ligne 6, de telle sorte que l'on puisse extraire à la main la partie 9 selon l'avant dernière étape du procédé.Similarly, one could still and without departing from the invention, provide no outer wing 12 and give the upper part 9 of the end piece a length allowing it to protrude sufficiently out of the base comprising for this purpose an internal stop at the end thread, after breaking along line 6, so that part 9 can be extracted by hand according to the penultimate stage of the process.
Il va de soi que tout autre moyen de solidarisation de la canule à l'une quelconque des parties 9 ou 10 de l'embout constituerait une simple adaptation qui ne sauraient en aucun cas sortir de la portée de l'invention ; ce serait par exemple le cas d'un embout conforme à l'invention mais dont la partie supérieure (9) serait lisse et viendrait ainsi s'emboîter juste dans le culot de la canule sur une hauteur suffisante pour obtenir la cassure de la ligne 6 par flexion de la canule. It goes without saying that any other means of securing the cannula to any one of the parts 9 or 10 of the nozzle would constitute a simple adaptation which cannot in any case depart from the scope of the invention; this would for example be the case with a tip according to the invention but the upper part (9) of which would be smooth and would thus fit just into the base of the cannula over a sufficient height to obtain the break in line 6 by bending the cannula.
