Description

La présente invention est relative à des perfectionnements apportés aux ensembles verseurs escamotables utilisés notamment bien que non exclusivement sur des bidons de manière à faciliter l'écoulement de leur contenu sans nuire à leur possibilité d'empilage.The present invention relates to improvements made to the retractable pouring assemblies used in particular although not exclusively on cans so as to facilitate the flow of their contents without harming their possibility of stacking.

Lorsque les verseurs en question sont associés à un bidon métallique tel qu'un bidon d'huile pour véhicule, ils comprennent généralement trois éléments : une embase encliquetée dans une ouverture du dessus du récipient, un verseur tubulaire propre à coulisser de manière étanche par rapport à l'embase afin de venir en saillie par rapport au récipient contre une butée appropriée, et un bouchon associé à l'extrémité libre du verseur.When the pourers in question are associated with a metal canister such as a canister of vehicle oil, they generally comprise three elements: a base snapped into an opening at the top of the container, a tubular pourer capable of sliding in leaktight relation to to the base in order to project from the container against an appropriate stop, and a plug associated with the free end of the pourer.

Les perfectionnements qui font l'objet de la présente invention visent à permettre la réalisation d'un verseur du genre en question qui réponde mieux que jusqu'à présent au divers desiderata de la pratique.The improvements which are the subject of the present invention aim to allow the production of a pourer of the genus in question which responds better than so far to the various wishes of the practice.

A cet effet le bouchon comporte une seconde jupe extérieure dont la face intérieure est pourvue de deux joncs séparés situés en vis-à-vis et qui s'encliquettent sous un cordon de l'embase tandis que la face extérieure de ladite jupe est associée à deux demi-anneaux constituant chacun levier destiné à assurer l'arrachage du bouchon par rapport au cordon précité de l'embase. Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :

  • Fig. 1 est une vue en coupe d'un ensemble verseur établi conformément à l'invention représenté en position effacée par rapport au-dessus d'un récipient.
  • Fig. 2 est une vue semblable à celle de fig. 1, mais illustrant le verseur à sa position sortie.
  • Fig. 3 montre le bouchon de fermeture du bec verseur en vue par dessous.
  • Fig. 4 est une vue partielle extérieure du dispositif suivant l'invention.
  • Fig. 5 illustre la manière dont le bouchon est dégagé de l'embase.
  • Fig. 6 est une vue par dessous du bec verseur selon l'invention suivant la flèche F (fig. 1).
To this end, the stopper has a second outer skirt, the inner face of which is provided with two separate rods located opposite and which snap under a bead of the base while the outer face of said skirt is associated with two half-rings each constituting a lever intended to ensure the tearing of the plug with respect to the aforementioned cord of the base. The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:
  • Fig. 1 is a sectional view of a pouring assembly established in accordance with the invention shown in the erased position relative to the top of a container.
  • Fig. 2 is a view similar to that of FIG. 1, but illustrating the pourer in its extended position.
  • Fig. 3 shows the closure cap of the spout seen from below.
  • Fig. 4 is a partial exterior view of the device according to the invention.
  • Fig. 5 illustrates the manner in which the plug is released from the base.
  • Fig. 6 is a view from below of the pouring spout according to the invention according to arrow F (FIG. 1).

0n a représenté en fig. 1 un ensemble verseur escamotable suivant l'invention associé au-dessus la d'un récipient 1 réalisé sous la forme d'un bidon métallique. Ce verseur est plus particulièrement disposé dans une ouverture lb pratiquée au centre d'un bossage lc du dessus précité.0n is shown in fig. 1 a retractable pouring assembly according to the invention associated above the container 1 made in the form of a metal container. This pourer is more particularly arranged in an opening 1b made in the center of a boss lc from the above-mentioned top.

L'ensemble verseur comprend une embase 2, un verseur tubulaire 3 et un bouchon 4 formant ce dernier, ces trois éléments étant réalisés en une matière plastique appropriée comme on l'expliquera mieux plus loin.The pouring assembly comprises a base 2, a tubular pourer 3 and a plug 4 forming the latter, these three elements being made of a suitable plastic material as will be explained better below.

L'embase 2 qui est réalisée en une matière telle que le polyéthylène comprend un manchon central 5 prolongé radialement par une collerette 6 qui comporte une extrémité 6a retournée vers le bas, une gorge 7 étant pratiquée immédiatement en dessous de la face inférieure de cette collerette. Le bas du manchon 5 est pourvu d'un bord 5a rabattu deux fois à 90° de manière à constituer une cheminée centrale mince 5b propre à coopérer de manière étanche avec la périphérie du bec tubulaire 3. La partie du manchon 5 située au-dessus de la collerette 6 est pourvue d'un cordon périphérique 8.The base 2 which is made of a material such as polyethylene comprises a central sleeve 5 extended radially by a flange 6 which has one end 6a turned downwards, a groove 7 being formed immediately below the underside of this flange . The bottom of the sleeve 5 is provided with an edge 5a folded twice at 90 ° so as to constitute a thin central chimney 5b capable of cooperating in leaktight manner with the periphery of the tubular spout 3. The part of the sleeve 5 situated above of the collar 6 is provided with a peripheral cord 8.

Comme représenté en fig. 2 l'embase 2 est encliquetée élastiquement à l'intérieur de l'ouverture lb déterminée dans le bossage lc du dessus la du récipient 1.As shown in fig. 2 the base 2 is snapped elastically inside the opening lb determined in the boss lc from above the of the container 1.

Le verseur tubulaire 3 réalisé aussi en polyéthylène comporte 1 sa partie supérieure un filetage 9 tandis que sa base est entourée par une bride périphérique 10. Le pourtour du bec 3 est pourvu d'un bourrelet 11 dont la distance à la bride 10 est au jeu près égale à la hauteur de la cheminée 5b.The tubular pourer 3 also made of polyethylene comprises 1 its upper part a thread 9 while its base is surrounded by a peripheral flange 10. The periphery of the spout 3 is provided with a bead 11 whose distance from the flange 10 is at play almost equal to the height of the chimney 5b .

Le bouchon 4 réalisé préférablement en polypropylène est pourvu d'une jupe 12 dont la face intérieure est filetée, son fond 4a qui comporte une lèvre annulaire 13 disposée plus au centre que la jupe 12, se prolongeant au-delà de celle-ci pour porter une seconde jupe 14 coaxiale à la première et dont la face intérieure est pourvue de deux joncs diamétralement opposés 14a, 14b (fig. 3) s'étendant sur environ le quart de la circonférence de la face considérée. La seconde jupe 14 est entourée de deux demi-panneaux 15, 16 dont la longueur est inférieure à sa demi-circonférence. Chaque anneau est rendu solidaire de cette dernière par l'intermédiaire de deux tenons 17.18, 19.20 situés deux à deux en vis-à-vis l'un de l'autre et au-delà de chacun desquels chaque demi-anneau dépasse pour former un pied 15a, 15b respectivement 16a, 16b. Chaque demi-anneau comporte encore une oreille centrale 15c, 16c facilitant la préhension comme on l'expliquera mieux plus loin. Enfin le pourtour de la jupe 14 est relié au milieu de chaque anneau par un pontet 21, 22.The plug 4, preferably made of polypropylene, is provided with a skirt 12, the inner face of which is threaded, its bottom 4a which comprises an annular lip 13 disposed more in the center than the skirt 12, extending beyond the latter to carry a second skirt 14 coaxial with the first and the inner face of which is provided with two diametrically opposite rods 14a, 14b (fig. 3) extending over approximately a quarter of the circumference of the face considered. The second skirt 14 is surrounded by two half-panels 15, 16 whose length is less than its half-circumference. Each ring is made integral with the latter by means of two tenons 17.18, 19.20 located two by two opposite one another and beyond each of which each half-ring projects to form a foot 15a, 15b respectively 16a, 16b. Each half-ring also has a central ear 15c, 16c facilitating gripping as will be explained better below. Finally, the periphery of the skirt 14 is connected to the middle of each ring by a bridge 21, 22.

En vue de son montage par rapport au récipient 1 l'assemblage du verseur s'effectue tout d'abord en engageant le bec dans l'embase 2 par son extrémité qui porte le filetage 9, cette opération s'effectuant à partir du dessous par rapport à la cheminée 5b. Le bouchon 4 est ensuite vissé à fond par rapport au filetage 9. Enfin le bec est escamoté de manière que le bouchon vienne se placer comme représenté en fig. 1 par rapport à l'embase 2. On a affaire à ce moment à un obturateur inviolable (fig. 4) dont les demi- anneaux 15, 16 reposent contre le dessus de la collerette 6. Lors du premier emploi, l'utilisateur saisit ensemble les deux oreilles 15c, 16c et agit sur elles pour faire pivoter les demi-anneaux dans le sens des flèches Fl, F2 (fig. 5) autour des pontets ce qui provoque d'abord la rupture des pontets d'inviolabilité 21, 22 puis la mise en contact de l'extrémité des pieds 15a, 15b, 16a, 16b avec le dessus de la collerette 6. Par suite de la qualité de la matière constituant le bouchon et de la dimension des tenons 17, 18, 19, 20 le soulèvement des anneaux au-delà de leur position correspondant au contact des pieds avec le dessus de la collerette 6 provoque le dégagement du bouchon par rapport aux joncs 14a, 14b par effet de levier de sorte que le bouchon se dégage de l'embase 2. Si l'utilisateur tire encore plus les deux demi-anneaux vers le haut il provoque la sortie du bec 3 jusqu'à ce que sa bride 10 vienne en contact avec le bord rabattu inférieur 5a de ladite embase (fig. 2). A ce moment le bec est axialement verrouillé entre le bourrelet 11 et la bride 10. Comme celle-ci comporte des saillies radiales 23 orientées vers l'extérieur (fig. 6), la rotation du bouchon encore solidaire angulairement du bec 3 amène ces saillies contre des butées 24 ménagées sous le bord inférieur de l'embase (flèche F3), ainsi le dévissage du bouchon peut s'effectuer facilement puisque le bec 3 devient fixe.In view of its mounting relative to the container 1, the pourer is assembled first by engaging the spout in the base 2 by its end which carries the thread 9, this operation being carried out from below by compared to the chimney 5b. The plug 4 is then screwed in completely with respect to the thread 9. Finally, the spout is retracted so that the plug comes to be placed as shown in FIG. 1 relative to the base 2. We are dealing at this time with a tamper-evident shutter (fig. 4) whose half-rings 15, 16 rest against the top of the flange 6. During the first use, the user grasps together the two ears 15c, 16c and acts on them to rotate the half-rings in the direction of the arrows Fl, F2 (fig. 5) around the bridges which firstly causes the tamper-evident bridges 21, 22 to break then bringing the ends of the feet 15a, 15b, 16a, 16b into contact with the above the collar 6. Owing to the quality of the material constituting the stopper and the size of the studs 17, 18, 19, 20 the lifting of the rings beyond their position corresponding to the contact of the feet with the top of the flange 6 causes the plug to be released relative to the rods 14a, 14b by leverage so that the plug is released from the base 2. If the user pulls the two half-rings even more upwards, it causes the outlet of the spout 3 until its flange 10 comes into contact with the lower folded edge 5a of said base (fig. 2). At this moment the spout is axially locked between the bead 11 and the flange 10. As the latter has radial projections 23 facing outwards (fig. 6), the rotation of the plug still angularly integral with the spout 3 brings these projections against stops 24 formed under the lower edge of the base (arrow F3), thus unscrewing the plug can be carried out easily since the spout 3 becomes fixed.

Après déversement du contenu du récipient lorsqu'on revisse le bouchon 4 sur le bec 3 celui-ci tourne dans le sens de la flèche F4 de manière que les saillies quittent les butées sur lesquelles elles sont en appui pour venir contre leurs voisines. On peut donc ainsi visser à fond le bouchon. Pour escamoter le bec il suffit d'appuyer sur le bouchon en direction du bas : la cheminée 5b se déforme légèrement au passage du bourrelet 11, enfin les joncs 14a, 14b viennent s'encliqueter sous le cordon 8 de l'embase. On notera qu'on prévoit avantageusement quatre saillies 23 et quatre butées 24.After the contents of the container have been spilled when the cap 4 is screwed back onto the spout 3, the latter rotates in the direction of the arrow F4 so that the projections leave the stops on which they are bearing to come against their neighbors. It is thus possible to screw the cap fully. To retract the spout, simply press the plug in the direction of the bottom: the chimney 5b deforms slightly when the bead 11 passes, finally the rods 14a, 14b snap under the cord 8 of the base. It will be noted that advantageously four projections 23 and four stops 24 are provided.

On notera la présence dans le fond du bouchon d'une seconde lèvre 26 (fig. 2) qui vient coopérer avec la périphérie intérieure du débouché 5c en vue d'assurer l'étanchéité lors du rebouchage aussi bien par rapport à l'intérieur de l'embase qu'à l'extérieur.Note the presence in the bottom of the cap of a second lip 26 (fig. 2) which comes to cooperate with the inner periphery of the outlet 5c in order to ensure sealing during the filling as well with respect to the interior of the base only outside.

On observe en fig. 6 la présence d'un croisillon 26 à l'intérieur du bec 3, son centre étant destiné à recevoir le point d'injection de l'élément en question.We observe in fig. 6 the presence of a spider 26 inside the spout 3, its center being intended to receive the point of injection of the element in question.

Cette pression s'établit à 40 bars et se maintient à cette valeur. On refroidit, dégaze l'autoclave, on chauffe tout en distillant à pression atmosphérique 2 heures à 130°C puis 2 heures à 150°C. Après traitements habituels, on obtient la benzoxazolone avec un R T de 57,5 % et un T T de 95 %.It is purged with nitrogen and heated for 8 hours at 170 ° C. The atmosphere under ammonia pressure is thus obtained by decomposition of urea in the presence of water. This pressure is established at 40 bars and is maintained at this value. Cooled, degassed the autoclave, heated while distilling at atmospheric pressure for 2 hours at 130 ° C. then 2 hours at 150 ° C. After usual treatments, benzoxazolone is obtained with an R T of 57.5% and a T T of 95%.

Exemple 10Example 10

Dans un autoclave de 140cm3 revêtu intérieurement de poly- tétrafluoroéthylène, on charge :

  • - 24 g d'orthochlorophénol
  • - 28 g d'urée
  • - 2,5 g de CuC12
  • - 6,35 g de NH3.
In an autoclave of 140 cm 3 coated on the inside with polytetrafluoroethylene, we load:
  • - 24 g of orthochlorophenol
  • - 28 g of urea
  • - 2.5 g of CuC1 2
  • - 6.35 g of NH 3 .

On ferme l'autoclave, purge à l'aide de NH3. On chauffe à 170°C pendant 6 heures. La pression se stabilise initialement à environ 26 bars (pression relative) puis descend progressivement jusqu'à environ 10 bars en fin de réaction. On refroidit à 120°C, ouvre l'autoclave, et transfère le contenu de l'autoclave dans un ballon de 250cm3 sous pression atmosphérique muni d'un système de distillation semblable à celui de l'exemple 1. Dans ce ballon on ajoute lentement 3 cm3 d'eau ; on chauffe alors 2 h. à 14O°C puis 2 h. à 150°C en ajoutant régulièrement de l'eau à raison de 4,5 cm3/h tout au long de la distillation. On refroidit à nouveau à 120°C, ajoute 80 cm3 d'eau, refroidit à 20°C, ajoute 15cm3 d'une solution aqueuse d'acide sulfurique 6 N, ajoute 50 cm3 d'acétate d'éthyle. On décante et sépare la phase aqueuse qu'on lave à l'aide d'acétate d'éthyle. Dans la phase organique on obtient de la benzoxazolone avec un RT de 30 % et un T T de 80 %.The autoclave is closed and purged using NH 3 . The mixture is heated at 170 ° C for 6 hours. The pressure initially stabilizes at around 26 bars (relative pressure) and then gradually drops to around 10 bars at the end of the reaction. Cool to 120 ° C., open the autoclave, and transfer the contents of the autoclave to a 250 cm 3 flask at atmospheric pressure fitted with a distillation system similar to that of Example 1. To this flask is added slowly 3 cm 3 of water; it is then heated for 2 hours. at 140 ° C and then 2 h. at 150 ° C by regularly adding water at the rate of 4.5 cm 3 / h throughout the distillation. Cool again to 120 ° C, add 80 cm 3 of water, cool to 20 ° C, add 15 cm 3 of a 6N aqueous sulfuric acid solution, add 50 cm 3 of ethyl acetate. The aqueous phase is decanted and separated, which is washed with ethyl acetate. In the organic phase, benzoxazolone is obtained with a RT of 30% and a TT of 80%.

On a également obtenu la benzoxazolone en présence de Fe C12, NiCl2 et Ni.Benzoxazolone was also obtained in the presence of Fe C1 2 , NiCl 2 and Ni.
