Description

La présente invention a pour objet un bidon ou récipient analogue comportant un goulot de versement qui est obturable par un bouchon se fixant sur ledit goulot et qui, à l'intérieur, est muni d'un dispositif de destruction, installé à demeure, pour un organe d'obturation fixé de façon étanche sur l'extrémité du goulot d'un flacon, ce dispositif comportant au moins une ouverture de passage pour le liquide contenu dans le flacon, un alésage de guidage pour le goulot du flacon et un organe de coupe qui est prévu au niveau de l'ouverture de passage.The subject of the present invention is a can or similar container comprising a pouring neck which can be closed off by a stopper which is fixed on said neck and which, inside, is provided with a destruction device, permanently installed, for a sealing member fixed in leaktight manner to the end of the neck of a bottle, this device comprising at least one passage opening for the liquid contained in the bottle, a guide bore for the neck of the bottle and a cutting member which is provided at the passage opening.

Un tel récipient est connu par le brevet US-3 270 524. Ce récipient est associé à un flacon de très petites dimensions et servant en même temps de bouchon. Le dispositif de destruction accroché sur le bord de l'embouchure tronconique évasée vers l'extérieur et disposé à l'intérieur de cette embouchure comporte près de sa petite base inférieure une ouverture ainsi qu'un couteau vertical de découpe prévu sur le bord de cette ouverture. Cette structure nécessite une disposition oblique de l'organe d'obturation du flacon et un positionnement très précis du flacon par rapport au récipient afin d'éviter un perçage intempestif de l'organe d'obturation du flacon. La zone découpée dans l'organe d'obturation du flacon est entourée sans beaucoup de jeu latéral par le dispositif de destruction, de sorte qu'un écoulemnt rapide du liquide contenu dans le flacon n'est pas assuré. En outre, aussi bien l'embouchure du récipient que celle du flacon ont une forme tronconique dont celle du récipient s'évase vers 1e haut et celle du flacon s'amincit vers l'ouverture du flacon renversé, les deux embouchures s'emboîtant l'une dans l'autre. Le mouvement rotatif de découpe du flacon par rapport au récipient est, de ce fait, fortement gêné et peut conduire au coincement du flacon.Such a container is known from US Pat. No. 3,270,524. This container is associated with a bottle of very small dimensions and at the same time serving as a stopper. The destruction device hung on the edge of the frustoconical mouth flared outwards and disposed inside this mouth has near its small lower base an opening and a vertical cutting knife provided on the edge of this opening. This structure requires an oblique arrangement of the closure member of the bottle and a very precise positioning of the bottle relative to the container in order to avoid inadvertent drilling of the closure member of the bottle. The area cut out in the closure member of the bottle is surrounded without much lateral play by the destruction device, so that a rapid flow of the liquid contained in the bottle is not guaranteed. In addition, both the mouth of the container and that of the bottle have a frustoconical shape in which that of the container flares upwards and that of the bottle tapers towards the opening of the inverted bottle, the two mouths fitting together. 'one in the other. The rotary cutting movement of the bottle relative to the container is therefore greatly hampered and can lead to jamming of the bottle.

Un autre récipient du type précité est connu par le brevet français 80 02075 (2 475 003). Dans ce cas, le dispositif de destruction comprend un organe de coupe cylindrique qui pénètre sans jeu latéral dans le goulot du flacon se vissant sur la partie supérieure du dispositif de destruction et enfonce l'organe d'obturation du flacon dans le goulot de celui-ci ; cet organe d'obturation se coince fréquemment dans l'organe de coupe cylindrique et bouche au moins partiellement l'ouverture d'écoulement délimitée par la face intérieure de l'organe de coupe cylindrique. Par ailleurs, la partie supérieure du dispositif de destruction, partie comportant l'organe de coupe est séparée du récipient lorsque l'on retire le flacon du goulot du récipient, de sorte que ce dernier ne peut être réutilisé dans les conditions initiales.Another container of the aforementioned type is known from French patent 80,02075 (2,475,003). In this case, the destruction device comprises a cylindrical cutting member which penetrates without lateral play in the neck of the bottle screwing onto the upper part of the destruction device and pushes the shutter member of the bottle into the neck of the latter. this ; this shutter member frequently gets stuck in the cylindrical cutting member and at least partially blocks the flow opening defined by the inner face of the cylindrical cutting member. Furthermore, the upper part of the destruction device, part comprising the cutting member is separated from the container when the bottle is removed from the neck of the container, so that the latter cannot be reused under the initial conditions.

En outre, on connaît des bidons ou récipients comportant un goulot de versement obturable par un bouchon se fixant sur ledit goulot, de préférence, par vissage. De tels bidons d'une contenance, par exemple, d'un litre, sont souvent réalisés en une matière thermoplastique et sont destinés à contenir un détergent ou un autre liquide de nettoyage tel que l'eau de javel. Ces bidons contiennent un liquide de nettoyage de faible concentration et servent, après consommation de leur contenu, au mélange d'une certaine quantité d'eau avec une dose de détergent concentré contenu généralement dans des berlingots mous en matière plastique dont la manipulation est difficile, sinon dangereuse dès leur ouverture jusqu'à leur vidange complète. Pour obtenir une solution d'eau javellisée à usage domestique, on mélange, par exemple, une dose d'eau de javel de 250 millilitres concentrée à 48° chlorométrique avec 750 millilitres d'eau pour obtenir un litre d'eau de javel à 12° chlorométrique dont la concentration convient aux usages ménagers.In addition, there are known cans or receptacles comprising a pouring neck which can be closed off by a plug which is fixed to said neck, preferably by screwing. Such cans with a capacity, for example, of one liter, are often made of a thermoplastic material and are intended to contain a detergent or another cleaning liquid such as bleach. These cans contain a low concentration cleaning liquid and are used, after consumption of their content, to mix a certain amount of water with a dose of concentrated detergent generally contained in soft plastic cartons whose handling is difficult, otherwise dangerous from their opening until their complete emptying. To obtain a bleach solution for household use, we mix, for example, a dose of bleach of 250 milliliters concentrated at 48 ° chlorometric with 750 milliliters of water to obtain a liter of bleach at 12 ° chlorometric, the concentration of which is suitable for household use.

Pour pouvoir réaliser ce mélange d'une dose de détergent concentré avec de l'eau dans le bidon, il faut découper le berlingot mou et verser son contenu dans le bidon. Cette opération est dan- geureuse car quelques gouttes du liquide concentré peuvent toujours tomber sur la peau ou le vêtement du manipulateur.To be able to mix this dose of concentrated detergent with water in the container, cut the soft carton and pour its contents into the container. This is dangerous because a few drops of the concentrated liquid can always fall on the operator's skin or clothing.

Le but de la présente invention vise à supprimer les inconvénients susmentionnés et à proposer un bidon permettant de transvaser dans le bidon, en toute sécurité, la dose concentrée contenue dans un flacon.The aim of the present invention is to eliminate the aforementioned drawbacks and to propose a container making it possible to safely pour the concentrated dose contained in a bottle into the container.

Ce but est atteint du fait que le dispositif de destruction comporte, d'une part, une paroi cylindrique dont la face intérieure délimite l'alésage de guide et, d'autre part, à son extrémité supérieure, une butée annulaire pouvant recevoir l'appui d'une partie élargie tronconique d'un flacon, butée dont la face intérieure est également tronconique et se raccorde, par son bord inférieur, à la face intérieure de ladite paroi cylindrique et que l'organe de coupe est prévu à l'extrémité inférieure de la paroi cylindrique et fait saillie vers l'axe de l'alésage de guidage.This object is achieved by the fact that the destruction device comprises, on the one hand, a cylindrical wall whose inner face delimits the guide bore and, on the other hand, at its upper end, an annular stop that can receive the support of an enlarged frustoconical part of a bottle, stop whose internal face is also frustoconical and is connected, by its lower edge, to the internal face of said cylindrical wall and that the cutting member is provided at the end bottom of the cylindrical wall and projects towards the axis of the guide bore.

On peut également atteindre ce but du fait que le dispositif de destruction comporte, d'une part, une paroi cylindrique dont la face intérieure délimite d'alésage de guidage et, d'autre part, à son extrémité supérieure, une butée annulaire pouvant recevoir l'appui d'une partie élargie tronconique d'un flacon, butée dont la face intérieure est également tronconique et se raccorde, par son bord inférieur, à la face intérieure de ladite paroi cylindrique et que l'organe de coupe est en forme de cône ou de pyramide creux qui est disposé coaxialement à l'intérieur de l'alésage de guidage et qui comprend une pointe dirigée vers le haut, une partie intermédiaire ajourée et une partie inférieure continue qui, à sa base, est raccordée à l'extrémité inférieure de la paroi cylindrique.This goal can also be achieved by the fact that the destruction device comprises, on the one hand, a cylindrical wall whose inner face delimits a guide bore and, on the other hand, at its upper end, an annular stop that can receive the support of an enlarged frustoconical part of a bottle, a stop whose internal face is also frustoconical and is connected, by its lower edge, to the internal face of said cylindrical wall and that the cutting member is in the form of cone or hollow pyramid which is arranged coaxially inside the guide bore and which comprises a point directed upwards, an openworked intermediate part and a continuous lower part which, at its base, is connected to the end bottom of the cylindrical wall.

Grâce à cette conception, l'organe d'obturation du flacon ou récipient analogue contenant la dose concentrée, est détruit sans difficulté et sans coincement du flacon après son introduction à l'intérieur du bidon, de sorte que le liquide concentré s'écoule rapidement et à travers une large section de passage dans le bidon. Bien entendu, il est préférable qu'au moins le goulot du flacon présente une certaine rigidité, mais on peut aussi utiliser des berlingots dont les parois très minces n'ont de tenue que lorsque lesdits berlingots sont entièrement remplis d'un liquide ou d'une pâte et dont une extrémité se termine par une sorte de goulot qui s'introduit dans le goulot du bidon où elle peut être détruite, par exemple percée, par le dispositif de destruction dudit bidon.Thanks to this design, the closure member of the bottle or similar container containing the concentrated dose is destroyed without difficulty and without jamming the bottle after its introduction. inside the container, so that the concentrated liquid flows quickly and through a large passage section in the container. Of course, it is preferable that at least the neck of the bottle has a certain rigidity, but it is also possible to use cartons whose very thin walls only hold when said cartons are completely filled with a liquid or a paste and one end of which ends in a sort of neck which is introduced into the neck of the container where it can be destroyed, for example pierced, by the device for destroying said container.

L'invention vise également un ensemble de récipients constitué, d'une part, d'un bidon du type précité muni dans son goulot d'un dispositif de destruction et, d'autre part, d'un flacon muni d'un goulot qui est obturé de façon étanche par un organe d'obturation et qui présente des dimensions telles que son organe d'obturation puisse être introduit dans le dispositif de destruction et présenté devant l'organe de coupe de celui-ci.The invention also relates to a set of containers consisting, on the one hand, of a can of the aforementioned type provided in its neck with a destruction device and, on the other hand, of a bottle provided with a neck which is sealed by a shutter member and which has dimensions such that its shutter member can be introduced into the destruction device and presented in front of the cutting member thereof.

Cet ensemble de récipients est caractérisé en ce que le goulot du flacon a un diamètre extérieur de quelques millimètres inférieur au diamètre intérieur de la paroi cylindrique du dispositif de destruction et qu'à l'endroit de la fixation de l'organe d'obturation sur le bord du goulot du flacon, ledit organe d'obturation ou ledit goulot comporte un bourrelet annulaire de guidage qui s'engage sans jeu latéral notable dans l'alésage de guidage du dispositif de destruction.This set of containers is characterized in that the neck of the bottle has an outside diameter of a few millimeters less than the inside diameter of the cylindrical wall of the destruction device and than at the point of attachment of the closure member to the edge of the neck of the bottle, said sealing member or said neck has an annular guide bead which engages without significant lateral play in the guide bore of the destruction device.

Cette adaptation du goulot du flacon et de son organe d'obturation au dispositif de destruction prévu dans le goulot du bidon procure une sécurité accrue lors de l'ouverture du flacon et du transvasement de son contenu liquide dans le bidon puisque ledit contenu du flacon ne peut s'écouler ailleurs que dans ledit bidon dès l'ouverture du flacon, la partie de flacon qui repose sur le goulot du bidon formant une sorte d'écran de protection contre les projections de liquide qui pourraient se produire lors de l'ouverture du flacon.This adaptation of the neck of the bottle and its closure member to the destruction device provided in the neck of the container provides increased security when the bottle is opened and its liquid content is transferred into the container since said content of the bottle does not can flow elsewhere than in said container from the opening of the bottle, the part of the bottle which rests on the neck of the container forming a kind of protective screen against liquid projections which could occur during the opening of the container. bottle.

Sur le dessin, on n'a représenté que l'extrémité supérieure, à savoir le goulot de versement 1 d'un bidon 2 ou récipient analogue réalisé, de préférence, en une matière thermoplastique. Le goulot 1 comporte un filetage 3 sur lequel se visse un bouchon d'obturation non représenté. A l'intérieur du goulot 1 d'une forme, de préférence, cylindrique, est fixé à demeure un dispositif de destruction 4 destiné à agir sur et à détruire un organe d'obturation qui fait partie intégrante d'un goulot 5 d'un flacon 6 ou est fixé de façon étanche sur le goulot de flacon. L'organe d'obturation 7 du goulot de flacon 5 peut être un simple opercule en matière thermoplastique qui, tout au moins sur le côté, est en contact avec le goulot 5 et est thermosoudé sur celui-ci lorsque le flacon 6 est en matière thermoplastique (figure 6). On peut aussi utiliser en tant qu'organe d'obturation 7 des bouchons creux, de préférence en matière thermoplastique, ayant l'extrémité de leur jupe collée ou thermosoudée sur le goulot 5 du flacon 6 (voir figures 1 à 4). Il est également possible d'utiliser des capsules ou éléments analogues en tant qu'organe d'obturation dans la mesure où ceux-ci peuvent être détruits sans difficulté par le dispositif de destruction 4 prévu dans le goulot 1 du bidon 2.In the drawing, only the upper end has been shown, namely the pouring neck 1 of a can 2 or similar container preferably made of a thermoplastic material. The neck 1 has a thread 3 onto which a sealing plug, not shown, is screwed. Inside the neck 1 of a shape, preferably cylindrical, is permanently fixed a destruction device 4 intended to act on and destroy a closure member which is an integral part of a neck 5 of a bottle 6 or is tightly fixed on the bottle neck. The closure member 7 of the bottle neck 5 can be a simple seal made of thermoplastic material which, at least on the side, is in contact with the neck 5 and is heat-sealed thereon when the bottle 6 is made of material. thermoplastic (Figure 6). It is also possible to use, as a closure member 7, hollow plugs, preferably made of thermoplastic material, having the end of their skirt bonded or heat-sealed to the neck 5 of the bottle 6 (see FIGS. 1 to 4). It is also possible to use capsules or similar elements as a sealing member insofar as these can be destroyed without difficulty by the destruction device 4 provided in the neck 1 of the container 2.

D'une façon générale, le flacon 6 contient une petite dose d'un produit liquide à forte concentration et le bidon 2 est destiné à contenir une plus grande quantité, par exemple un litre d'un liquide, par exemple, détergent de faible concentration résultant du mélange dans le bidon 2 d'une certaine quantité d'eau avec le contenu concentré du flacon 6.In general, the bottle 6 contains a small dose of a high concentration liquid product and the container 2 is intended to contain a larger quantity, for example a liter of a liquid, for example, low concentration detergent resulting from the mixing in the canister 2 of a certain amount of water with the concentrated content of the bottle 6.

Le dispositif de destruction 4 disposé à l'intérieur du goulot 1 du bidon 2 comporte au moins une ouverture de passage 8 permettant, d'une part, au liquide contenu dans le flacon 6 - après destruction de l'organe d'obturation 7 de celui-ci - de s'écouler dans le bidon 2, et, d'autre part, au contenu du bidon d'être déversé hors dudit bidon 2. Avantageusement, le dispositif de destruction 4 comprend, au-dessus de l'ouverture de passage 8, un alésage de guidage 9 pour le goulot 5 du flacon 6 en position renversée ; en outre, ce dispositif de destruction 4 comporte une paroi, de préférence, cylindrique 10 dont la section transversale a un pourtour de configuration adapté à la forme de la face intérieure 11 du goulot 1 du bidon 2, la face intérieure coaxiale 12 de la paroi cylindrique 10 délimitant l'alésage de guidage 9. Au niveau de l'ouverture de passage 8 (figures 1 et 2) ou des ouvertures de passage 8 (figures 4 et 5) est prévu un organe de coupe 13 qui, selon le mode de réalisation des figures 1 et 2 est constitué par une pointe, de préférence, triangulaire présentant une forme analogue à un double soc permettant de trancher par la droite et/ou par la gauche, cet organe de coupe 13 étant disposé, par exemple, sur le bord vertical 17 de l'ouverture de passage 8 et s'étend, par sa pointe, radialement vers et perpendiculairement à l'axe 14 du goulot 1 du bidon 2. Comme on peut le voir sur les figures 1 et 2, l'organe de coupe en forme de soc 13 est prévu à l'extrémité inférieure de la paroi cylindrique 10 du dispositif de destruction 4 et fait saillie radialement vers l'axe de l'alésage de guidage 9, axe confondu avec l'axe 14 du goulot 1. Près de son extrémité inférieure, la paroi cylindrique 10 comporte une butée annulaire inférieure 15 matérialisée par un épaulement interne dont la face supérieure annulaire 16 est située au-dessus et à proximité de l'organe de coupe 13 et dont la face intérieure coaxiale 17 porte ledit organe de coupe 13 et délimite l'ouverture de passage 8, les faces 16 et 17 étant raccordées, de préférence, par un chanfrein tronconique 47.The destruction device 4 disposed inside the neck 1 of the container 2 has at least one passage opening 8 allowing, on the one hand, the liquid contained in the bottle 6 - after destruction of the closure member 7 of the latter - to flow into the container 2, and, on the other hand, the contents of the container to be poured out of said container 2. Advantageously, the destruction device 4 comprises, above the opening of passage 8, a guide bore 9 for the neck 5 of the bottle 6 in the inverted position; in addition, this destruction device 4 comprises a wall, preferably cylindrical 10, the cross section of which has a configuration periphery adapted to the shape of the internal face 11 of the neck 1 of the container 2, the coaxial internal face 12 of the wall cylindrical 10 defining the guide bore 9. At the passage opening 8 (Figures 1 and 2) or the passage openings 8 (Figures 4 and 5) there is provided a cutting member 13 which, according to the embodiment of FIGS. 1 and 2, consists of a point, preferably a triangular one having a shape similar to a double ploughshare making it possible to cut from the right and / or by the left, this cutting member 13 being arranged, for example, on the vertical edge 17 of the passage opening 8 and extends, by its point, radially towards and perpendicular to the axis 14 of the neck 1 of the container 2. As can be seen in FIGS. 1 and 2, the share-shaped cutting member 13 is provided at the lower end of the cylindrical wall 10 of the destruction device 4 and projects radially towards the axis of the guide bore 9, axis coincides with the axis 14 of the neck 1. Near its lower end, the cylindrical wall 10 has a lower annular stop 15 materialized by an internal shoulder whose annular upper face 16 is located above and at proximity to the cutting member 13 and the inner face of which coaxial 17 carries said cutting member 13 and defines the passage opening 8, the faces 16 and 17 being preferably connected by a frustoconical chamfer 47.

A l'extrémité supérieure du dispositif de destruction 4, extrémité supérieure qui peut se trouver à fleur ou légèrement en dessous du bord 18 du goulot 1 du flacon 2, est prévue une butée annulaire supérieure 20 dont la face intérieure 21 est tronconique et présente un bord inférieur qui correspond à la petite base du tronc de cône délimitée par ladite face intérieure 21 et qui se raccorde vers le bas, à la face intérieure 12 de la paroi cylindrique 10. La face extérieure 22 de la butée annulaire supérieure 20 est, de préférence, cylindrique et présente un pourtour qui est sensiblement identique à celui de la face intérieure du goulot de bidon 1 de sorte que ladite butée annulaire supérieure 20 du dispositif de destruction 4 est montée par friction et à force dans le goulot 1 du bidon 2. Le bord inférieur de la face extérieure 22 de la butée annulaire 20 se raccorde à la face extérieure 23 de la paroi cylindrique 10 au niveau de l'extrémité supérieure de celle-ci par un épaulement annulaire intérieur 24. Le pourtour de la face extérieure 22 de la butée annulaire supérieure 20 peut être légèrement tronconique de façon à se rétrécir très faiblement de haut en bas, le diamètre extérieur de ladite butée 20 étant tel qu'elle puisse être engagée de force dans le goulot 1 du bidon 2. On comprendra aisément que la butée annulaire supérieure 20 joue non seulement le rôle d'une butée, mais sert aussi, en coopération avec une partie élargie 25 du goulot 5 du flacon 6, à former une sorte de chicane ou d'écran empêchant le liquide de sortir du goulot 1 lors du transvasement du liquide concentré du flacon 6 au bidon 2.At the upper end of the destruction device 4, the upper end which may be flush with or slightly below the edge 18 of the neck 1 of the bottle 2, an upper annular stop 20 is provided, the inner face 21 of which is frustoconical and has a lower edge which corresponds to the small base of the truncated cone delimited by said inner face 21 and which is connected downwards to the inner face 12 of the cylindrical wall 10. The outer face 22 of the upper annular stop 20 is, from preferably cylindrical and has a periphery which is substantially identical to that of the inner face of the canister neck 1 so that said upper annular stop 20 of the destruction device 4 is mounted by friction and by force in the neck 1 of the canister 2. The lower edge of the outer face 22 of the annular stop 20 is connected to the outer face 23 of the cylindrical wall 10 at the upper end of the latter by an annu inner space 24. The periphery of the outer face 22 of the upper annular stop 20 may be slightly frustoconical so as to narrow very slightly from top to bottom, the outside diameter of said stop 20 being such that it can be forcibly engaged in the neck 1 of the container 2. It will be readily understood that the upper annular stop 20 not only acts as a stop, but also serves, in cooperation with an enlarged part 25 of the neck 5 of the bottle 6, to form a sort of baffle or screen preventing the liquid from leaving the neck 1 during the transfer of the concentrated liquid from the bottle 6 to the canister 2.

La face extérieure 22 de la butée annulaire supérieure 20 est munie d'une série de cannelures et de nervures 25, 26 qui s'étendent parallèlement à l'axe 14 du dispositif 4 et dont chaque cannelure 25 alterne avec une nervure voisine 26. Les nervures 26 s'agrippent à la face intérieure 11 du goulot 1 du bidon 2 et peuvent, le cas échéant, avec les cannelures 25 et les parties correspondantes de la face intérieure 11 du goulot 1, délimiter des canaux d'aération 27 dont la section transversale est insuffisante pour permettre le passage d'un liquide.The outer face 22 of the upper annular stop 20 is provided with a series of grooves and ribs 25, 26 which extend parallel to the axis 14 of the device 4 and each groove 25 of which alternates with a neighboring rib 26. The ribs 26 grip the inner face 11 of the neck 1 of the container 2 and can, if necessary, with the grooves 25 and the corresponding parts of the inner face 11 of the neck 1, delimit ventilation channels 27 whose cross-section transverse is insufficient to allow the passage of a liquid.

La face intérieure 21 de la butée annulaire supérieure 20 peut également être munie d'une série de cannelures et de nervures radiales de faible section pour faciliter le passage d'air lorsqu'un flacon 6 est introduit dans le goulot 1 du bidon 2.The internal face 21 of the upper annular stop 20 can also be provided with a series of grooves and radial ribs of small section to facilitate the passage of air when a bottle 6 is introduced into the neck 1 of the container 2.

La face extérieure 23 de la paroi cylindrique 10 du dispositif de destruction a, en général, un diamètre plus petit de quelques millimètres au moins que la face intérieure 11 du goulot 1 du bidon 2 et comporte plusieurs nervures radiales extérieures de raidissement 28. Les sommets 29 des nervures de raidissement 28, par exemple au nombre de quatre, s'inscrivent dans le cylindre ou très faible tronc de cône déterminé par la face extérieure 22 de la butée annulaire supérieure 20 et s'appliquent contre la face intérieure 11 du goulot du bidon 2.The external face 23 of the cylindrical wall 10 of the destruction device has, in general, a diameter smaller by a few millimeters at least than the internal face 11 of the neck 1 of the container 2 and comprises several external radial stiffening ribs 28. The vertices 29 stiffening ribs 28, for example four in number, fit into the cylinder or very small truncated cone determined by the outer face 22 of the upper annular stop 20 and are applied against the inner face 11 of the neck of the can 2.

Bien que le bidon 2 muni d'un dispositif de destruction 4 conforme au mode de réalisation représenté sur les figures 1 et 2 puisse coopérer avec des flacons de structures diverses à condition que ceux-ci comportent un organe d'obturation destructible ou un élément assimilable à un organe d'obturation destructible qui puisse être présenté devant l'organe de coupe 13 et être détruit par celui-ci, il peut être avantageux d'associer au bidon 2 des figures 1 et 2 un flacon 6 tel que représenté sur la figure 3.Although the container 2 provided with a destruction device 4 in accordance with the embodiment shown in FIGS. 1 and 2 can cooperate with bottles of various structures provided that these comprise a destructible closure member or an assimilable element with a destructible closure member which can be presented in front of the cutting member 13 and be destroyed by it, it may be advantageous to associate with the canister 2 of FIGS. 1 and 2 a bottle 6 as shown in the figure 3.

Le flacon 6 de la figure 3 comporte un goulot 5 dont le diamètre extérieur est inférieur, par exemple, de quelques millimètres au diamètre intérieur de l'alésage de guidage 9 délimité par la face intérieure 12 de la paroi cylindrique 10 et sa hauteur peut être inférieure à la hauteur dudit alésage 9. A son extrémité inférieure, le goulot 5 du flacon 6 est raccordé à une partie élargie tronconique ou pyramidale 30 qui, lorsque c'est nécessaire, ne s'oppose pas à la rotation du goulot 5 dans le goulot 1 du bidon 2 et qui s'évase vers le bas et présente une forme et une inclinaison adpatées à celles de la face intérieure 21 de la butée annulaire supérieure 20 du dispositif de destruction 4. De préférence, on réalise au moins le flacon 6 et, le cas échéant, aussi son organe d'obturation 7 en une matière thermoplastique et thermosoudable et on choisit tout au moins pour le goulot 5, et de préférence, aussi pour la partie élargie 30 du flacon 6 une épaisseur de paroi suffisante pour que, pour une matière donnée, ledit goulot 5 et la partie élargie 30 soient au moins semi-rigides sinon, de préférence, rigides.The bottle 6 of FIG. 3 has a neck 5 whose outside diameter is less, for example, by a few millimeters than the inside diameter of the guide bore 9 delimited by the inside face 12 of the cylindrical wall 10 and its height can be less than the height of said bore 9. At its lower end, the neck 5 of the bottle 6 is connected to an enlarged frustoconical or pyramidal part 30 which, when necessary, does not oppose the rotation of the neck 5 in the neck 1 of the can 2 and which flares down and has a shape and an inclination adapted to those of the inner face 21 of the upper annular stop 20 of the destruction device 4. Preferably, at least the bottle 6 is produced and, where appropriate, also its closure member 7 made of a thermoplastic and heat-sealable material, and at least for the neck 5, and preferably also for the enlarged part 30 of the bottle 6, a wall thickness sufficient for , for r a given material, said neck 5 and the enlarged part 30 are at least semi-rigid if not, preferably, rigid.

Comme on peut le voir sur le dessin, à l'endroit de la fixation de l'organe d'obturation 7 sur le bord du goulot 5 du flacon 6, ledit organe d'obturation 7 (figures 1 et 3) ou ledit goulot 5 (figures 4 et 6) comporte un bourrelet annulaire de guidage 31 qui s'engage sans jeu latéral notable dans l'alésage de guidage 9 du dispositif de destruction 4 et qui, lorsque la hauteur du goulot 5 au-dessus de la partie élargie 30 le permet, porte, le cas échéant, contre la face supérieure 16 de la butée annulaire inférieure 15 dudit dispositif de destruction 4 (figure 1). Le bourrelet de guidage 31 comporte, sur son pourtour cylindrique, une série de rainures verticales 32, de préférence, uniformément réparties sur tout son pourtour.As can be seen in the drawing, at the location of the closure member 7 on the edge of the neck 5 of the bottle 6, said closure member 7 (Figures 1 and 3) or said neck 5 (Figures 4 and 6) has an annular guide bead 31 which engages without significant lateral play in the guide bore 9 of the destruction device 4 and which, when the height of the neck 5 above the widened part 30 allows it, bears, if necessary, against the upper face 16 of the lower annular stop 15 of said destruction device 4 (FIG. 1). The guide bead 31 has, on its cylindrical periphery, a series of vertical grooves 32, preferably, uniformly distributed over its entire periphery.

Selon le mode de réalisation représenté sur la figure 6, l'organe d'obturation 7 du goulot 5 du flacon 6 est un opercule fixé sur l'extrémité du goulot de flacon 5 dans un épaulement intérieur 33 pratiqué dans le bourrelet de guidage 31 du goulot 5. Par contre, selon les modes de réalisation représentés sur les figures 1 à 4, l'organe d'obturation 7 du flacon 6 est constitué par un bouchon comprenant une paroi frontale d'obturation 34 et une jupe latérale cylindrique 35 dont l'extrémité inférieure est fixée à demeure sur le bord du goulot 5 du flacon 6. Le mode de fixation de la jupe 35 sur le goulot 5 peut varier d'un type d'organe de fixation à l'autre. Ce qui importe cependant, c'est que la liaison entre au moins une partie de la jupe 35 et le goulot 5 subsiste en permanence même après la destruction du bouchon. Pour connaître plus de détails sur les différents modes de réalisation et de fixation des bouchons, il convient de se reporter à la demande de brevet parallèle déposée ce même jour et ayant pour titre « Bouchon destructible à usage unique et récipients munis d'un tel bouchon •. Selon le mode de réalisation représenté sur les figures 1 à 3, le diamètre extérieur de la jupe cylindrique 35 de l'organe d'obturation 7 est légèrement plus petit que celui de l'ouverture de passage 8 du dispositif de destruction et la jupe latérale cylindrique et verticale 35 comporte un méplat vertical 36 permettant de faire passer ladite jupe 35 devant l'organe de coupe 13 du dispositif de destruction 4. A partir de cette position, dans laquelle le goulot 5 repose par l'intermédiaire du bourrelet de guidage 31 sur la butée annulaire inférieure 15 ou le flacon 6 repose par l'intermédiaire de sa partie élargie tronconique 30 sur la butée annulaire supérieure 20, il suffit de faire tourner le flacon 6 autour de l'axe 14 du bidon 2 pour que l'organe de coupe 13 découpe la plus grande partie de la jupe latérale 35 à l'exception d'une partie centrale du méplat 36, partie centrale qui ne peut venir en contact avec ledit organe de coupe 13. Pour faciliter la découpe, c'est-à-dire la destruction de l'organe d'obturation 7 et l'ouverture du flacon 6, on peut prévoir une entaille annulaire 37 sur la zone de jupe qui se présentera devant l'organe de coupe 13.According to the embodiment shown in FIG. 6, the shutter member 7 of the neck 5 of the bottle 6 is a cover fixed on the end of the bottle neck 5 in an internal shoulder 33 formed in the guide bead 31 of the neck 5. On the other hand, according to the embodiments shown in FIGS. 1 to 4, the closure member 7 of the bottle 6 is constituted by a stopper comprising a front closure wall 34 and a cylindrical side skirt 35 of which l 'lower end is fixed permanently on the edge of the neck 5 of the bottle 6. The method of fixing the skirt 35 on the neck 5 may vary from one type of fixing member to another. What is important, however, is that the connection between at least part of the skirt 35 and the neck 5 remains permanently even after the plug has been destroyed. For more details on the different embodiments and fixing of the plugs, it is necessary to refer to the parallel patent application filed on the same day and having for title "Destructible plug for single use and containers provided with such a plug •. According to the embodiment shown in Figures 1 to 3, the outer diameter of the cylindrical skirt 35 of the closure member 7 is slightly smaller than that of the passage opening 8 of the destruction device and the side skirt cylindrical and vertical 35 has a vertical flat 36 allowing said skirt 35 to pass in front of the cutting member 13 of the destruction device 4. From this position, in which the neck 5 rests by means of the guide bead 31 on the lower annular stop 15 or the bottle 6 rests via its enlarged frustoconical part 30 on the upper annular stop 20, it suffices to rotate the bottle 6 around the axis 14 of the can 2 so that the member cutting 13 cuts most of the side skirt 35 with the exception of a central part of the flat 36, central part which can not come into contact with said cutting member 13. To facilitate cutting, that is to say the destru ction of the closure member 7 and the opening of the bottle 6, an annular notch 37 can be provided on the skirt area which will appear in front of the cutting member 13.

Selon le mode de réalisation représenté sur les figures 4 et 5, l'organe de coupe 13 du dispositif de destruction 4 présente un cône ou une pyramide creux 38 qui est disposé coaxialement à l'intérieur de l'alésage de guidage 9. Cet organe de coupe 13 en forme de cône ou de pyramide comprend, de haut en bas, une pointe 39 dirigée vers le haut et, de préférence, située dans l'axe 14 du goulot 1 du bidon 2, une partie intermédiaire ajourée 40 dont les ajours constituent les ouvertures de passage 8 précédemment mentionnées, et une partie inférieure continue 41, c'est-à-dire sans ajours, qui, à sa base, est raccordée à l'extrémité inférieure de la paroi cylindrique 10. Les ajours ou ouvertures de passage 8 de la partie intermédiaire 40 de l'organe de coupe 13 sont délimités, d'une part, latéralement par des barrettes coupantes 42 qui s'étendent suivant les génératrices du cône 38 ou des arêtes de la pyramide 38, et, d'autre part, à leur bord inférieur, par le bord supérieur 43 de la partie inférieure 41 de l'organe de coupe 13, 38. Dans certains cas, il est avantageux de donner à la pointe 39 et à la partie inférieure continue 41 de l'organe de coupe 13, 38 la même inclinaison par rapport à l'axe 14 du goulot 1 du bidon 2 ; et du dispositif de destruction, cette inclinaison étant relativement faible, par exemple de l'ordre de 5 à 15°, et sensiblement plus faible que celle de la partie intermédiaire 40 par rapport audit axe 14 du dispositif de destruction 4. L'inclinaison de la partie intermédiaire 40, c'est-à-dire des barrettes coupantes 42 par rapport à l'axe 14 est de l'ordre de 15 à 50°. Grâce à cette conception, on déchire d'abord avec la pointe 39 la partie centrale de la paroi frontale d'obturation 34 ou de l'opercule de l'organe d'obturation et découpe ensuite radialement vers l'extérieur ladite paroi 34 à l'aide des barrettes coupantes 42 sur toute l'étendue de la partie intermédiaire 40 de manière à obtenir des lambeaux triangulaires de bouchon 44 qui sont écartés des ouvertures de passage ou ajours 8 lorsque leur base se place par dessus la partie inférieure continue 41 de l'organe de coupe 13, 38. Ainsi, le liquide concentré contenu dans le flacon peut facilement passer à travers les ouvertures de passage découvertes 8 de la partie intermédiaire 40 de l'organe de coupe 13, 38. L'embase de l'organe de coupe 13, 38 est raccordée à l'extrémité inférieure de la paroi cylindrique 10 à l'aide de languettes radiales de liaison 45 qui délimitent deux par deux et avec les bords inférieurs correspondants de ladite paroi cylindrique 10 et de la partie inférieure 41 de l'organe de coupe 13, 38 des trous de communication 46 qui sont de forme oblongue et courbe et permettent aux quantités de liquide qui sont passées entre la partie inférieure 41 de l'organe de coupe 13, 38 et la base des lambeaux de bouchon 44, de tomber également dans le bidon 2. Le dispositif de destruction 4 peut être réalisé en un métal léger ou un alliage de métaux légers mais également en une matière plastique rigide de haute résistance.According to the embodiment shown in Figures 4 and 5, the cutting member 13 of the destruction device 4 has a cone or a hollow pyramid 38 which is arranged coaxially inside the guide bore 9. This member of cut 13 in the shape of a cone or pyramid comprises, from top to bottom, a point 39 directed upwards and, preferably, situated in the axis 14 of the neck 1 of the can 2, an intermediate perforated part 40 whose openings constitute the passage openings 8 previously mentioned, and a continuous lower part 41, that is to say without openings, which, at its base, is connected to the lower end of the cylindrical wall 10. The openings or openings of passage 8 of the intermediate part 40 of the cutting member 13 are delimited, on the one hand, laterally by cutting bars 42 which extend along the generatrices of the cone 38 or of the edges of the pyramid 38, and, on the other hand, at their lower edge, by the upper edge 43 of the part lower 41 of the cutting member 13, 38. In some cases, it is advantageous to give the tip 39 and the continuous lower part 41 of the cutting member 13, 38 the same inclination relative to the axis 14 of the neck 1 of the can 2; and of the destruction device, this inclination being relatively small, for example of the order of 5 to 15 °, and substantially smaller than that of the intermediate part 40 relative to said axis 14 of the destruction device 4. The inclination of the intermediate part 40, that is to say cutting bars 42 relative to the axis 14 is of the order of 15 to 50 °. Thanks to this design, the central part of the front shutter wall 34 or of the cover of the shutter member is first torn with the tip 39 and then cut said wall 34 at radially outwards. using cutting bars 42 over the entire extent of the intermediate part 40 so as to obtain triangular plug flaps 44 which are spaced from the passage openings or openings 8 when their base is placed over the continuous lower part 41 of the cutting member 13, 38. Thus, the concentrated liquid contained in the bottle can easily pass through the uncovered passage openings 8 of the intermediate part 40 of the cutting member 13, 38. The base of the member section 13, 38 is connected to the lower end of the cylindrical wall 10 using radial connecting tabs 45 which delimit two by two and with the corresponding lower edges of said cylindrical wall 10 and of the lower part 41 of the o cutter 13, 38 of the communication holes 46 which are oblong and curved and allow the quantities of liquid which have passed between the lower part 41 of the cutter 13, 38 and the base of the plug flaps 44, also falling into the container 2. The destruction device 4 can be made of a light metal or a light metal alloy but also of a rigid plastic of high resistance.

Il va de soi que les différents modes de réalisation précédemment décrits peuvent subir un certain nombre de modifications sans que l'on sorte pour cela du champ de protection dont les limites sont définies par les revendications annexées.It goes without saying that the various embodiments described above can undergo a certain number of modifications without going beyond the protective field, the limits of which are defined by the appended claims.
