Abstract

The combined stopper and pouring spout is for use on plastics bottles etc., comprising a body (2) together with a cap (9) and a guarantee seal. The body incorporates an annular spout (8) and fits on the bottle opening in an airtight manner, the cap houses demountably onto the body to close the spout, and the seal comprises a band (16) which is torn off prior to the first use. The bottom edge of the cap has an internally projecting annular outstand (13) together with externally projecting teeth (15), the former engaging a similar body formation (14), whilst the latter fits between easily breakable bars (18) connecting the band to the body. The arrangement improves resistance to internal pressure. The bars project from raised sectors (19), and the band comprises a belt located by a cross wall (5) and a lip (17).

Description

La présente invention a trait aux bouchons verseurs en matière plastique moulée, destinés à équiper les bouteilles et autres récipients analogues en vue d'en assurer l'obturation tout en en garantissant le contenu jusqu'au moment de la première utilisation. The present invention relates to molded plastic pouring caps, intended to equip bottles and other similar containers with a view to ensuring their closure while guaranteeing the contents thereof until the time of first use.

On sait que les bouchons verseurs de ce type comprennent généralement un corps propre à être fixé de manière étanche sur l'ouverture du récipient et pourvu axialement d'un bec verseur annulaire, un capuchon amovible de fermeture agence de manière å coiffer le corps précité en obturant le bec de celui-ci, et une bande déchirable de garantie assurant l'assemblage desdits corps et capuchon jusqu'au moment de la première utilisation. It is known that pouring caps of this type generally comprise a body capable of being tightly fixed on the opening of the container and provided axially with an annular pouring spout, a removable closure cap arranged so as to cover the aforementioned body in closing the spout thereof, and a tear-off guarantee strip ensuring the assembly of said bodies and cap until the time of first use.

Le problème principal qui se pose dans la conception de ce genre de bouchons réside dans la retenue en place du capuchon amovible, cette retenue devant être efficace jusqu'à la première ouverture afin de s'opposer à tout risque d'expulsion dudit capuchon sous l'effet d'une pression interne engendrée lors du stockage du récipient à l'étant plein, tout en étant beaucoup plus faible lors de l'utilisation ultérieure dudit récipient afin de ne pas gêner celle-ci. The main problem which arises in the design of this kind of plugs resides in the retention in place of the removable cap, this retention having to be effective until the first opening in order to oppose any risk of expulsion of said cap under the effect of an internal pressure generated during storage of the container when full, while being much weaker during the subsequent use of said container so as not to interfere with it.

C'est ce problème que la présente invention a entendu résoudre de manière simple et parfaitement satisfaisante, et ce en faisant simultanément comporter à la base du capuchon amovible d'une part un relief annulaire tourné vers l'intérieur afin de venir s'encliqueter au-dessous d'un rebord prévu à cet effet sur la paroi externe du corps, et d'autre part une série de dents espacées tournées vers l'extérieur en vue de venir se disposer entre les pontets qui assurent la liaison å faible résistance entre la base de garantie entourant ledit capuchon et la partie du corps située dans le prolongement de la bande précitée. It is this problem that the present invention has intended to resolve in a simple and perfectly satisfactory manner, and this by making simultaneously comprise at the base of the removable cap on the one hand an annular relief turned inwards in order to snap into place. below a rim provided for this purpose on the external wall of the body, and on the other hand a series of spaced teeth turned towards the outside in order to come to be disposed between the bridges which ensure the connection at low resistance between the warranty base surrounding said cap and the part of the body situated in the extension of the aforementioned strip.

Le dessin annexe, 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 montre, moitié en élévation, moitie en coupe axiale, un bouchon verseur du type inviolable établi conformement à la présente invention.
The accompanying drawing, given by way of example, will make it possible to better understand the invention, the characteristics which it presents and the advantages which it is likely to provide.
Fig. 1 shows, half in elevation, half in axial section, a tamper-evident type pouring plug established in accordance with the present invention.

Fig. 2 est une coupe axiale partielle à plus grande échelle. Fig. 2 is a partial axial section on a larger scale.

En fig. 1 la référence 1 désigne la partie supérieure du col d'une bouteille usuelle en matière synthétique, cette partie étant profilée en la pour assurer la retenue du corps du bouchon verseur, lequel corps a été désigné en 2 en fig. 2. Ce corps 2 comprend à sa base deux parois annulaires concentriques 3 et 4 réunies à leur sommet par une cloison transversale 5, la paroi 4 présentant sur sa paroi interne une saillie 6 destinée à coopérer avec le profil la du col 1. Au-dessus de la cloison 5, le corps 2 est raidi par un croisillon transversal 7 qui opère la régulation de lécoulement liquide, et il se prolonge vers le haut par un manchon axial 8 conforme de manière à constituer bec verseur. In fig. 1 the reference 1 designates the upper part of the neck of a conventional plastic bottle, this part being profiled in the to ensure the retention of the body of the pouring plug, which body has been designated in 2 in fig. 2. This body 2 comprises at its base two concentric annular walls 3 and 4 joined at their top by a transverse partition 5, the wall 4 having on its internal wall a projection 6 intended to cooperate with the profile 1a of the neck 1. Au- above the partition 5, the body 2 is stiffened by a transverse cross 7 which operates the regulation of the liquid flow, and it is extended upwards by an axial sleeve 8 conforming so as to constitute a spout.

A ce corps 2 est associé un capuchon amovible de fermeture 9, réalisé en une matière synthétique plus rigide que celle qui forme le corps 2. Ce capuchon 9 comprend un fond transversal 10 solidaire d'une part d'une cheminée cylindrique 11 propre à obturer de manière étanche le bec verseur 8 du corps 2, et d'autre part d'une jupe cylindrique 12 concentrique à ladite cheminée 11.L'on observera que la base de cette jupe 12 comporte
- d'une part un bourrelet 13 qui fait saillie sur sa paroi interne en vue de venir s'encliqueter au-dessous d'un relief ou rebord annulaire 14 prévu obliquement dans la zone commune de raccordement de la cloison 5, du bec verseur 8 et du croisillon 7 du corps 2 ;
- et d'autre part une série de dents 15 tournes vers I'extérieur de façon à venir se disposer entre les organes qui rassurent, avec une faible résistance au déchirage, la jonction de la cloison transversale 5 et du bord inférieur d'une bande de garantie 16.
With this body 2 is associated a removable closure cap 9, made of a more rigid synthetic material than that which forms the body 2. This cap 9 comprises a transverse bottom 10 secured on the one hand to a cylindrical chimney 11 suitable for closing off sealingly the pouring spout 8 of the body 2, and on the other hand a cylindrical skirt 12 concentric with said chimney 11. It will be observed that the base of this skirt 12 comprises
- On the one hand a bead 13 which projects on its internal wall in order to snap below an annular relief or rim 14 provided obliquely in the common zone of connection of the partition 5, of the pouring spout 8 and of the cross member 7 of the body 2;
- And on the other hand, a series of teeth 15 facing outwards so as to be placed between the members which reassure, with low tear resistance, the junction of the transverse partition 5 and the lower edge of a strip warranty 16.

Cette bande de garantie 16, munie à la façon usuelle d'une tirette de manoeuvre (non représentée), ceinture la jupe 12 du capuchon 3 en se trouvant protégée par une partie en redan 17 prévue au niveau du fond 10 dudit capuchon. Les organes qui assurent la liaison de cette bande 16 avec le corps 2 sont constitués, dans l'exemple de réalisation envisage, par des pontets 18 réunissant le bord inférieur de ladite bande à des secteurs espacés 19 solidaires de la face supérieure de la cloison transversale annulaire 5. Bien entendu ces organes 18-19 sont prévus de manière à présenter une section de passage suffisante pour que la bande 16 et le corps 2 soient susceptibles d'entre obtenus en une seule opération de moulage. This guarantee strip 16, provided in the usual way with an operating puller (not shown), surrounds the skirt 12 of the cap 3 while being protected by a step portion 17 provided at the bottom 10 of said cap. The members which ensure the connection of this strip 16 with the body 2 are constituted, in the embodiment envisaged, by bridges 18 joining the lower edge of said strip to spaced sectors 19 integral with the upper face of the transverse partition annular 5. Of course, these members 18-19 are provided so as to have a sufficient cross-section so that the strip 16 and the body 2 are capable of being obtained in a single molding operation.

On comprend que par suite des parties 13 et 15 prévues à l'oppose les unes des autres 8-la base du capuchon 9 et tout particulièrement grâce à la coopération du bord inférieur de la bande 16 et des dents extérieures 15, l'on obtient une retenue particulièrement efficace de ce capuchon sur le corps 2, retenue qui le met radEalement à l'abri de tout risque d'expulsion sous 11 effet d'une pression interne aussi longtemps que la bande 16 précitée est en place.Par contre, lorsque cette bande 16 a été éliminée par déchirage à l'occasion de la première utilisation de la bouteille 1, la retenue du capuchon n'est plus assurée que par la coopération des parties 13 et 14 qui opèrent en encliquetage relativement doux, non susceptible de gêner en quoi que ce soit l'utilisation normale de la bouteille. It is understood that as a result of the parts 13 and 15 provided at the opposite of each other 8-the base of the cap 9 and very particularly thanks to the cooperation of the lower edge of the strip 16 and the outer teeth 15, one obtains a particularly effective retention of this cap on the body 2, a retention which radially protects it from any risk of expulsion under the effect of internal pressure as long as the aforementioned strip 16 is in place. However, when this strip 16 has been eliminated by tearing during the first use of the bottle 1, the retention of the cap is no longer ensured except by the cooperation of the parts 13 and 14 which operate in relatively soft snap-in, not liable to interfere in whatever normal use of the bottle.

I1 va de soi qu'on peut imaginer d'autres formes de réalisation pour les organes qui assurent la jonction de la bande 16 et du corps 2, pour autant que ces organes laissent place aux dents extérieures 15 coopérant avec le bord inférieur de ladite bande. It goes without saying that other embodiments can be imagined for the members which provide the junction of the strip 16 and the body 2, provided that these members give way to the external teeth 15 cooperating with the lower edge of the said strip. .

I1 doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents.  It should moreover be understood that the above description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
