Description

La présente invention concerne un récipient muni d'un organe verseur obturé par un bouchon, tel que bouteille ou flacon, de préférence, en matière plastique, à usage unique et destiné à contenir une dose unitaire d'un liquide dangereux pour la santé, tel qu'un liquide caustique.The present invention relates to a container provided with a pouring member closed by a stopper, such as a bottle or flask, preferably of plastic material, for single use and intended to contain a unit dose of a liquid dangerous for health, such than a caustic liquid.

On sait que des liquides de nettoyage tels que l'eau de javel sont des produits caustiques d'autant plus dangereux qu'ils sont très concentrés, cette concentration servant à permettre de les contenir dans des emballages de faible volume. Afin d'éviter des accidents, il convient de ne pas entreposer ces produits concentrés de nettoyage dans des récipients ouverts et d'utiliser entièrement en une seule fois la dose contenue dans le récipient fermé. Pour obtenir une solution javellisée à usage domestique, on doit utiliser une dose d'eau de javel concentrée de 250 ml à 48 degrés chlorométriques avec 750 ml d'eau pour obtenir un litre d'eau de javel à 12 degrés chlorométriques dont la concentration convient aux usages ménagers. Jusqu'à présent, ces doses unitaires de produit liquide caustique concentré sont contenues dans des berlingots ou flacons mous en matière plastique dont la manipulation est difficile sinon dangereuse dès leur ouverture jusqu'à leur vidange complète.It is known that cleaning liquids such as bleach are caustic products which are all the more dangerous as they are very concentrated, this concentration serving to allow them to be contained in small volume packaging. In order to avoid accidents, these concentrated cleaning products should not be stored in open containers and the entire dose contained in the closed container should be used up in one go. To obtain a bleach solution for household use, you must use a concentrated dose of bleach of 250 ml at 48 chlorometric degrees with 750 ml of water to obtain a liter of bleach at 12 chlorometric degrees whose concentration is suitable for household use. Until now, these unit doses of concentrated caustic liquid product have been contained in soft plastic bottles or flasks, the handling of which is difficult if not dangerous from their opening until their complete emptying.

La présente invention supprime les inconvénients susmentionnés et a pour but un récipient du type indiqué au début qui présente une bonne maniabilité et incite l'utilisateur à consommer en une seule fois toute la dose de liquide contenue dans le récipient.The present invention eliminates the aforementioned drawbacks and aims at a container of the type indicated at the start which has good maneuverability and encourages the user to consume at once the entire dose of liquid contained in the container.

Ce but est atteint conformément à l'invention du fait que le récipient comprend un goulot rigide en tant qu'organe verseur, un fond au moins semi-rigide et des parois latérales au moins se- mi-rigides, que les parties de la paroi de fond sont inclinées par rapport à l'axe du goulot et du récipient d'un angle suffisant pour que ledit récipient ne puisse tenir dans la position debout, que le bouchon présentant de façon connue en soi une paroi d'obturation prolongée vers le fond par jupe latérale, est lui-même destructible et doit être détruit pour l'ouverture du récipient et est fixé de façon étanche sur le bord libre du goulot par l'intermédiaire de l'extrémité arrière ou inférieure de la jupe latérale, extrémité inférieure fixée à demeure sur ledit bord de goulot. Il est avantageux de prévoir qu'entre son extrémité inférieure et la paroi d'obturation, la jupe latérale comporte une bande annulaire fermée munie d'une languette de préhension et reliée à la partie inférieure et à la partie supérieure de la jupe ou à la paroi d'obturation par des zones annulaires d'affaiblissement permetant la destruction du bouchon et le déchirement de la jupe par traction sur la languette de préhension.This object is achieved in accordance with the invention because the container comprises a rigid neck as a pouring member, an at least semi-rigid bottom and at least semi-rigid side walls, as the parts of the wall bottom are inclined with respect to the axis of the neck and of the container at an angle sufficient for said container to be able to hold in the upright position, only the cap having, in a manner known per se, a closure wall extended towards the bottom by side skirt, is itself destructible and must be destroyed for the opening of the container and is tightly fixed on the free edge of the neck through the rear or lower end of the side skirt, lower end fixed permanently on said edge of the neck. It is advantageous to provide that between its lower end and the closure wall, the side skirt has a closed annular band provided with a gripping tab and connected to the lower part and to the upper part of the skirt or to the sealing wall by annular zones of weakness allowing the destruction of the plug and the tearing of the skirt by traction on the gripping tab.

Grâce à cette conception, le récipient ou flacon est également manipulable avec toute la sécurité requise pendant son vidage et du fait que le bouchon est détruit il ne peut être réutilisé après l'ouverture du récipient et aussi du fait que ledit récipient ne tient pas debout, l'utilisateur est incité à utiliser le contenu entier du récipient et à jeter celui-ci aussitôt après son vidage.Thanks to this design, the container or bottle can also be handled with all the security required during emptying and the fact that the cap is destroyed it cannot be reused after the opening of the container and also because the said container does not stand upright , the user is encouraged to use the entire contents of the container and discard it immediately after emptying.

D'autres caractéristiques importantes et avantages de l'invention ressortiront de la description suivante de plusieurs modes de réalisation d'un récipient conforme à l'invention, description faite en référence au dessin annexé sur lequel:

  • la figure 1 est une vue schématique latérale en élévation d'un récipient obturé en position couchée selon l'invention;
  • la figure 2 est une vue latérale d'une coupe verticale à travers le récipient suivant la ligne II-II de la figure 1;
  • la figure 3 est une vue schématique latérale d'une variante du fond du récipient;
  • la figure 4 est une vue frontale du bouchon du récipient obturé en position couchée;
  • la figure 5 est une vue d'une coupe axiale à travers le bouchon et le goulot du récipient selon la ligne V-V de la figure 4, et
  • la figure 6 est une vue d'une coupe transversale du bouchon selon la ligne VI-VI de la figure 5.
Other important characteristics and advantages of the invention will emerge from the following description of several embodiments of a container according to the invention, description made with reference to the appended drawing in which:
  • Figure 1 is a schematic side view in elevation of a closed container in the lying position according to the invention;
  • Figure 2 is a side view of a vertical section through the container taken along line II-II of Figure 1;
  • Figure 3 is a schematic side view of a variant of the bottom of the container;
  • Figure 4 is a front view of the cap of the container closed in the supine position;
  • FIG. 5 is a view of an axial section through the stopper and the neck of the container along the line VV of FIG. 4, and
  • FIG. 6 is a view of a cross section of the plug along the line VI-VI of FIG. 5.

Tel qu'on peut le voir sur le dessin, le récipient à dose unitaire 1 tel qu'une petite bouteille ou un flacon est réalisé, de préférence, en une matière plastique, par exemple, à l'aide d'une opération de moulage par extrusion-soufflage ou injection- soufflage, cette matière plastique étant imperméable à l'air. Le récipient 1 comprend en tant qu'organe verseur un goulot 2 qui est rigide et qui s'évase vers l'arrière, c'est-à-dire vers le fond, pour se raccorder aux parois latérales 3 qui sont au moins semi-rigides, sinon rigides et qui se terminent par le fond 4 qui, pour sa part, est de préférence rigide et tout au moins semi-rigide et comporte des parties de fond 4a, 4b etc. suffisamment inclinées par rapport à l'axe 5 du récipient 1 ou de son goulot 2 pour que, - à aucun état de remplissage (plein, vide, presque vide, semi-rempli) - le récipient ne puisse se tenir debout, c'est-à-dire dans une position dans laquelle l'axe 5 est vertical. Les génératrices des parois latérales 3 peuvent être parallèles à l'axe 5 du goulot 2 et du flacon 1, mais en vue d'inciter l'utilisateur à ne conserver aucun reste du contenu du récipient 1 après l'ouverture de celui-ci, il est avantageux de donner également aux parois latérales une forme courbe ou bombée 3a (voir traits interrompus figure 1). Cé qui supprime même la position stable du récipient 1 lorsqu'il repose sur des faces latérales planes 3 (voir figure 2) qui, dans certains cas, sont plus avantageuses, notamment en vue de réduire le volume de transport occupé par plusieurs récipients.As can be seen in the drawing, the unit dose container 1 such as a small bottle or a vial is preferably made of a plastic material, for example, using a molding operation by extrusion blow molding or injection blow molding, this plastic material being impermeable to air. The container 1 comprises as a pouring member a neck 2 which is rigid and which flares backwards, that is to say towards the bottom, to be connected to the side walls 3 which are at least semi rigid, if not rigid and which terminate in the bottom 4 which, for its part, is preferably rigid and at least semi-rigid and comprises bottom parts 4a, 4b etc. sufficiently inclined with respect to the axis 5 of the container 1 or of its neck 2 so that, - in no filling state (full, empty, almost empty, semi-filled) - the container cannot stand upright, this is that is to say in a position in which the axis 5 is vertical. The generatrices of the side walls 3 can be parallel to the axis 5 of the neck 2 and of the bottle 1, but with a view to inciting the user to keep no residue of the contents of the container 1 after the opening of the latter, it is advantageous to also give the side walls a curved or domed shape 3a (see broken lines in Figure 1). This eliminates even the stable position of the container 1 when it rests on flat side faces 3 (see FIG. 2) which, in certain cases, are more advantageous, in particular with a view to reducing the transport volume occupied by several containers.

Avantageusement, la section transversale du récipient 1 peut être circulaire, ovale etc. ou s'inscrire dans un triangle, un rectangle, un carré ou tout autre polygone. Il est également avantageux de prévoir un fond bombé 4 comportant plusieurs parties de fond courbes 4a, 4b, 4c, 4d qui convergent vers l'axe 5. A chaque point de surface, par exemple 6, du fond bombé 4, on peut associer une tangente 7 qui est située dans un plan radial comprenant l'axe 5 et qui inclut avec ledit axe 5 un angle A ou β compris de préférence entre 15° et 75° ou entre 105° et 165°, ces angles étant en tout cas différents de 90° et suffisants pour empêcher le récipient 1 de pouvoir se tenir debout. On peut également prévoir un fond plat 4 incliné par rapport à l'axe 5 d'un angle :\ ou/7'(voirfigure 3).Advantageously, the cross section of the container 1 can be circular, oval, etc. or register in a triangle, a rectangle, a square or any other polygon. It is also advantageous to provide a curved bottom 4 comprising several curved bottom parts 4a, 4b, 4c, 4d which converge towards the axis 5. At each point of surface, for example 6, of the convex bottom 4, it is possible to associate a tangent 7 which is situated in a radial plane comprising the axis 5 and which includes with said axis 5 an angle A or β preferably between 15 ° and 75 ° or between 105 ° and 165 °, these angles being in any case different from 90 ° and sufficient to prevent the container 1 from being able to stand. One can also provide a flat bottom 4 inclined with respect to the axis 5 by an angle: \ or / 7 '(see Figure 3).

L'extrémité libre du goulot rigide 2 est obturée par un bouchon destructible 8 qui présente la particularité d'être fixé à demeure sur le bord 2a du goulot 2. Le bouchon destructible 8 qui présente une section transversale similaire à celle du goulot 2, par exemple circulaire, ovale, ou polygonale, comprend une paroi d'obturation 8a qui s'étent transversalement à l'axe 5, et peut être légèrement bombée soit vers l'extérieur, soit de préférence vers l'intérieur du bouchon et qui est prolongée vers le bas (c'est-à-dire vers le fond 4) par une jupe latérale 8b dont l'extrémité inférieure ou arrière 8c est conformée en un bourrelet muni d'une rainure ou gorge annulaire coaxiale 8d dont les flancs latéraux 8e coiffent le bord 2a du goulot 2. Le bouchon 8 peut également être réalisé en une matière plastique et la fixation étanche dudit bouchon 8 sur le bord 2a du goulot 2 peut se faire par collage ou par soudure lorsque le flacon et le bouchon sont en matière thermoplastique.The free end of the rigid neck 2 is closed by a destructible plug 8 which has the particularity of being permanently fixed to the edge 2a of the neck 2. The destructible plug 8 which has a cross section similar to that of the neck 2, by example circular, oval, or polygonal, comprises a closure wall 8a which extend transversely to the axis 5, and can be slightly curved either outwardly, or preferably inwardly of the plug and which is extended downwards (that is to say towards the bottom 4) by a lateral skirt 8b, the lower or rear end 8c of which is shaped as a bead provided with a coaxial annular groove or groove 8d, the lateral flanks 8e of which cover the edge 2a of the neck 2. The stopper 8 can also be made of a plastic material and the tight fixing of said stopper 8 on the edge 2a of the neck 2 can be done by gluing or by welding when the bottle and the stopper are made of thermoplastic material .

A partir de la face extérieure de la jupe latérale 8 sont ménagées dans celle-ci deux gorges annulaires 9, 10 parallèles entre-elles et perpendiculaires à l'axe 5 du goulot 2. Ces gorges annulaires 9, 10 se trouvent en face de zones annulaires d'affaiblissement 11, 12 dont l'épaisseur est plus faible que l'épaisseur normale de la paroi de la jupe latérale 8 et peuvent être déchirées. Les gorges annulaires 9, 10 et les zones d'affaiblissement 11, 12 délimitent dans la jupe 8 une bande annulaire de déchirement 13 qui, par l'intermédiaire d'une pièce d'écartement radial 14, est reliée à une languette de préhension 15 s'étendant, sur une courte distance, parallèlement à la bande 13. Comme on peut le voir sur la figure 6, la bande de déchirement 13 présente au voisinage immédiat de la pièce d'écartement 14, dans sa partie recouverte par la languette de préhension 15, un amincissement 16 facilitant le début de l'arrachement de la partie de bande solidaire de la pièce d'écartement 14. Bien entendu, le bouchon 8 étant réalisé en une matière plastique et venu de moulage, tous les éléments constitutifs dudit bouchon 8 sont d'une seule pièce. L'épaisseur de la jupe et la largeur ou hauteur axiale de la bande de déchirement 13 sont telles que la résistance à la traction de ladite bande 13 soit suffisante pour assurer le déchirement de la jupe 8b aux endroits des zones d'affaiblissement 11, 12, c'est-à-dire des gorges 9, 10 et pour empêcher à la fois la rupture de ladite bande 13. Pour éviter que la partie de jupe 8b solidaire de la paroi 8a après arrachement de la bande 13 ne puisse servir de bouchon, il est avantageux de prévoir la deuxième zone d'affaiblissement 12 au voisinage immédiat du bord de la paroi d'obturation 8a.From the outer face of the side skirt 8 are formed therein two annular grooves 9, 10 parallel to each other and perpendicular to the axis 5 of the neck 2. These annular grooves 9, 10 are located opposite zones annular weakening 11, 12 whose thickness is less than the normal thickness of the wall of the side skirt 8 and can be torn. The annular grooves 9, 10 and the weakening zones 11, 12 define in the skirt 8 an annular tear strip 13 which, by means of a radial spacer 14, is connected to a gripping tongue 15 extending, over a short distance, parallel to the strip 13. As can be seen in FIG. 6, the tear strip 13 present in the immediate vicinity of the spacer 14, in its part covered by the tongue of gripping 15, a thinning 16 facilitating the start of the tearing off of the strip part secured to the spacer 14. Of course, the plug 8 being made of a plastic material and molded, all the constituent elements of said plug 8 are in one piece. The thickness of the skirt and the axial width or height of the tear strip 13 are such that the tensile strength of said strip 13 is sufficient to ensure the tear of the skirt 8b at the locations of the weakening zones 11, 12 , that is to say grooves 9, 10 and to prevent both the rupture of said strip 13. To prevent the skirt portion 8b secured to the wall 8a after tearing of the strip 13 can not serve as a plug , it is advantageous to provide the second weakening zone 12 in the immediate vicinity of the edge of the closure wall 8a.

Grâce à l'invention, l'ouverture du récipient 1 est extrêmement simple et sans danger et doit se faire par la destruction du bouchon 8. Il suffit de tirer sur la languette de préhension 15 de façon à la faire tourner autour du goulot 2 à partir de son extrémité libre en direction de la pièce d'écartement 14. On constatera que la bande de déchirement 13 se séparera complètement de la partie inférieure de la jupe 8, partie inférieure comprenant le bourrelet 8c et fixée à demeure sur le goulot 2, et que sur une faible longueur, elle restera attachée à la partie supérieure de la jupe 8 ou à la paroi d'obturation 8a, ce qui évite tout contact des doigts avec cette dernière.Thanks to the invention, the opening of the container 1 is extremely simple and safe and must be done by destroying the plug 8. It suffices to pull the gripping tab 15 so as to rotate it around the neck 2 to from its free end in the direction of the spacer 14. It will be seen that the tear strip 13 will separate completely from the lower part of the skirt 8, the lower part comprising the bead 8c and fixed permanently to the neck 2, and that over a short length, it will remain attached to the upper part of the skirt 8 or to the closure wall 8a, which avoids any contact of the fingers with the latter.

Les différents modes de réalisation précédemment décrits peuvent subir un certain nombre de modifications sans que l'on sorte pour cela du cadre de protection défini par les revendications annexées. Il est notamment entendu que la structure du bouchon utilisé en combinaison avec le récipient peut être différente de celle décrite ci-dessus, à condition que la jupe du bouchon soit rendue à demeure solidaire du goulot du récipient et comporte une bande de déchirement qui, une fois enlevée, détruit le bouchon et ouvre en même temps le récipient. Le récipient précédemment décrit peut être muni d'un bouchon tel que décrit dans la demande de brevet intitulée »Bouchon destructible à usage unique et flacon muni d'un tel bouchon« et déposée ce même jour au nom du titulaire de la présente demande de brevet. Les gorges annulaires 9, 10 et les zones d'affaiblissement correspondantes 11, 12 ne sont pas nécessairement parallèles entre elles et perpendiculaires à l'axe 5 du goulot 2. Ces gorges 9, 10 peuvent également s.'entrécou- per ou être plus ou moins inclinées l'une sur l'autre sans s'entrecouper, la languette de préhension 15 étant avantageusement attachée à la partie la plus large de la bande de déchirement délimitée par lesdites gorges.The various embodiments described above can undergo a number of modifications without departing from the protective framework defined by the appended claims. It is understood in particular that the structure of the stopper used in combination with the container may be different from that described above, provided that the skirt of the stopper is permanently fixed to the neck of the container and includes a tear strip which, once removed, destroys the cap and at the same time opens the container. The container described above can be provided with a stopper as described in the patent application entitled "Destructible stopper for single use and bottle provided with such a stopper" and deposited on the same day in the name of the holder of this patent application. . The annular grooves 9, 10 and the corresponding weakening zones 11, 12 are not necessarily parallel to each other and perpendicular to the axis 5 of the neck 2. These grooves 9, 10 can also intersect or be more or less inclined to each other without intersecting, the gripping tab 15 being advantageously attached to the widest part of the tear strip delimited by said grooves.

Compte tenu de la forme particulière du fond 4 du récipient 1, il peut être avantageux de prévoir pour le transport groupé de plusieurs,récipients 1 dans des boîtes en carton, un moyen permettant de maintenir debout les récipients. A cet effet, on prévoit entre l'extrémité inférieure des parois latérales 3 du récipient 1 et le bord des parties de fond inclinées 4a, 4b, 4c, 4d un rétreint de placement 16 qui comprend un épaulement d'appui 17 de faible largeur et perpendiculaire à l'axe 5 et une paroi latérale 18 en retrait de la largeur de l'épaulement d'appui 17 par rapport aux parois latérales 3 et de faible hauteur. Les récipients 1 peuvent s'engager par leur rétreint 16 dans les alvéoles de forme correspondante d'une plaque alvéolée de support placée dans la boîte en carton.Given the particular shape of the bottom 4 of the container 1, it may be advantageous to provide for the grouped transport of several, containers 1 in cardboard boxes, a means for keeping the containers upright. For this purpose, there is provided between the lower end of the side walls 3 of the container 1 and the edge of the inclined bottom parts 4a, 4b, 4c, 4d a restricted placement 16 which comprises a support shoulder 17 of small width and perpendicular to the axis 5 and a side wall 18 set back from the width of the support shoulder 17 relative to the side walls 3 and of low height. The containers 1 can engage by their constriction 16 in the cells of corresponding shape of a honeycomb support plate placed in the cardboard box.
