Description

La présente invention concerne un emballage pour produit pulvérulent qui comporte un dispositif de fermeture perfectionné.The present invention relates to a packaging for powdered product which comprises an improved closure device.

On connait déjà des dispositifs permettant de délivrer une quantité donnée de produit caustique, utilisé notamment pour le débouchage de lavabos.Devices are already known which make it possible to deliver a given quantity of caustic product, used in particular for unclogging sinks.

Un tel dispositif pour déboucher les lavabos est décrit plus particulièrement dans le brevet suisse n° 543 426.Such a device for unblocking sinks is described more particularly in Swiss Patent No. 543,426.

Le dispositif décrit dans ce brevet comporte un boîtier inférieur muni d'un couvercle-supérieur et, à sa partie inférieure, muni de fentes dentelées, une collerette étant prévue entre le bord inférieur de ce boîtier et le couvercle. Le dispositif comporte, en outre, un boîtier inférieur qui peut coulisser par rapport au boîtier supérieur. Il comporte une première partie cylindrique supérieure, une seconde partie cylindrique inférieure, et une partie conique intermédiaire. Le dispositif comporte, en outre un obturateur conique qui est fixé à la partie inférieure du boîtier supérieur et qui coopère avec le boîtier inférieur lors de la fermeture du dispositif.The device described in this patent comprises a lower housing provided with an upper cover and, at its lower part, provided with serrated slots, a flange being provided between the lower edge of this housing and the cover. The device further comprises a lower housing which can slide relative to the upper housing. It comprises a first upper cylindrical part, a second lower cylindrical part, and an intermediate conical part. The device further comprises a conical shutter which is fixed to the lower part of the upper housing and which cooperates with the lower housing when the device is closed.

Le rôle de cet obturateur est de permettre l'écoulement du produit pulvérulent qui se trouve dans le boîtier supérieur, le produit pulvérulent, lorsque le dispositif est ouvert, coulant le long des parois de l'obturateur conique qui est alors désolidarisé du conteneur inférieur et le produit. pulvérulent passant au travers des fentes du boîtier supérieur.The role of this shutter is to allow the flow of the pulverulent product which is in the upper case, the pulverulent product, when the device is open, flowing along the walls of the conical shutter which is then detached from the lower container and the product. powder passing through the slots in the upper case.

L'obturateur dont la pointe du cone est dirigée vers le boîtier supérieur comporte, en outre, une branche dirigée depuis le boîtier supérieur vers le boîtier inférieur. Cette branche centrale a une double fonction. En premier lieu, elle permet de positionner le dispositif dans le lavabo de façon que ce dispositif soit situé axialement par rapport à l'ouverture de vidange du lavabo. La seconde fonction de cette branche est d'empêcher l'ouverture par inadvertance du dispositif. En effet, la branche dépassant légèrement du boîtier inférieur lorsque le dispositif est placé sur un plan continu, lorsque l'utilisateur appuie sur le couvercle du boîtier supérieur, la branche qui repose sur le plan continu s'oppose à l'ouverture.The shutter, the tip of the cone of which is directed towards the upper case, further comprises a branch directed from the upper case to the lower case. This central branch has a dual function. Firstly, it makes it possible to position the device in the sink so that this device is located axially with respect to the drain opening of the sink. The second function of this branch is to prevent inadvertent opening of the device. Indeed, the branch slightly protruding from the lower housing when the device is placed on a continuous plane, when the user presses on the cover of the upper housing, the branch which rests on the continuous plane opposes the opening.

Ce dispositif ne permet pas une fermeture totale. En effet, la branche s'oppose à l'ouverture c'est-à-dire à la désoli- darisation du boîtier supérieur et du boîtier inférieur, lorsque l'utilisatéur effectue une pression axiale. Mais la branche ne permet pas une fermeture correcte lorsque l'utilisateur effectue une rotation autour de l'axe longitudinal du dispositif et par une telle rotation et une poussée simultanée, l'utilisateur peut ouvrir un tel dispositif.This device does not allow total closure. Indeed, the branch opposes the opening, that is to say the separation of the upper housing and the lower housing, when the user is carrying out an axial pressure. However, the branch does not allow correct closure when the user rotates about the longitudinal axis of the device and by such rotation and simultaneous pushing, the user can open such a device.

Ceci comporte un grave inconvénient car le produit pulvérulent contenu dans le boîtier supérieur est en général un produit dangereux, plus particulièrement à base de soude caustique et si un enfant effectue une poussée et une rotation simultanée, il peut ouvrir par inadvertance le dispositif et recevoir du produit pulvérulent sur les mains ou sur une autre partie du corps, ce qui peut provoquer des accidents.This has a serious drawback because the powdery product contained in the upper casing is generally a dangerous product, more particularly based on caustic soda and if a child pushes and rotates simultaneously, he can inadvertently open the device and receive powdery product on the hands or on another part of the body, which can cause accidents.

L'invention vise à pallier ces inconvénients.The invention aims to overcome these drawbacks.

Un but de l'invention est de fournir un emballage pour produit pulvérulent, notamment produit caustique qui ne puisse pas être ouvert par inadvertance et donc comportant une fermeture de sécurité.An object of the invention is to provide a packaging for a pulverulent product, in particular a caustic product which cannot be opened inadvertently and therefore comprises a safety closure.

Un tel emballage est constitué-d'un boîtier supérieur pseudo-cylindrique, fermé à son extrémité supérieure, comportant à sa partie extrême inférieure des orifices ménagés dans sa paroi,

  • - d'un boîtier inférieur co-axial au boîtier supérieur dont la partie supérieure est pseudo-cylindrique de rayon r, la partie inférieure est pseudo-cylindrique de rayon R supérieur au rayon de la partie supérieure, et d'une partie médiane pseudo-conique, le boîtier inférieur étant ouvert à ses deux extrémités,
  • - d'un obturateur placé à l'intérieur de et coopérant avec le boîtier inférieur, muni de moyens de solidarisation avec le bord libre de la partie extrême inférieure du boîtier supérieur, l'ensemble du boîtier supérieur-obturateur coulissant axialement entre une position de fermeture et une position d'ouverture maximum,
  • - des moyens de fixation temporaire de la partie extrême inférieure de l'ensemble du boîtier supérieur-obturateur avec le boîtier inférieur, qui, lorsqu'ils sont actifs, déterminent la fermeture,
  • - des moyens d'arrêt du coulissement axial de l'ensemble boîtier supérieur-obturateur par rapport au boîtier inférieur, qui, lorsqu'ils sont actifs, déterminent la position d'ouverture maximum.
Such packaging consists of a pseudo-cylindrical upper housing, closed at its upper end, comprising at its lower end portion orifices formed in its wall,
  • - from a lower housing co-axial to the upper housing, the upper part of which is pseudo-cylindrical with radius r, the lower part is pseudo-cylindrical with radius R greater than the radius of the upper part, and a middle part pseudo- conical, the lower case being open at both ends,
  • - a shutter placed inside and cooperating with the lower case, provided with means for securing with the free edge of the lower end part of the upper case, the whole of the upper case-shutter sliding axially between a position of closing and a maximum opening position,
  • - means for temporarily fixing the lower end part of the assembly of the upper shutter box with the lower box, which, when they are active, determine closure,
  • - Means for stopping the axial sliding of the upper housing-shutter assembly relative to the lower housing, which, when active, determine the maximum opening position.

Un tel dispositif est caractérisé par le fait qu'il comporte des moyens de blocageen position fermée dont la fonction estd'empêcher le coulissement axial tout en permettant la rotation axiale de l'ensemble boîtier supérieur-obturateur par rapport au boîtier inférieur.Such a device is characterized in that it comprises locking means in the closed position, the function of which is to prevent axial sliding while allowing the axial rotation of the upper housing-shutter assembly relative to the lower housing.

Les moyens de blocage sont constitués par au moins un butoir venant en butée sur une saillie circulaire comportant au moins une discontinuité, le butoir lorsqu'il n'est pas en regard de la discontinuité, empêchant le coulissement axial.The locking means consist of at least one stopper abutting on a circular projection comprising at least one discontinuity, the stopper when it is not opposite the discontinuity, preventing axial sliding.

Le butoir peut, selon un mode de réalisation de l'invention, être situé sur le boîtier inférieur et la saillie peut être située sur le boîtier supérieur.The stopper can, according to one embodiment of the invention, be located on the lower case and the projection can be located on the upper case.

Au contraire, selon un autre mode de réalisation, le butoir est situé sur le boîtier supérieur et la saillie est située sur le boîtier inférieur.On the contrary, according to another embodiment, the stopper is located on the upper case and the projection is located on the lower case.

Le butoir et la saillie peuvent être d'autre part situés dans l'espace interne compris entre la paroi externe du boîtier supérieur et la paroi interne du boîtier inférieur.The stopper and the projection may also be located in the internal space between the external wall of the upper housing and the internal wall of the lower housing.

Le butoir et la saillie peuvent être situés sur les parois externes des boîtiers.The stopper and the projection can be located on the outer walls of the housings.

Le butoir, selon un mode de réalisation de l'invention, est un pivot et la saillie discontinue est un clip ou selon un deuxième mode de réalisation, le butoir est une patte longitudinale, la saillie discontinue étant une collerette disposée sur la paroi externe du boîtier supérieur, le bord libre de la patte venant en butée sur la saillie.The stopper, according to one embodiment of the invention, is a pivot and the discontinuous projection is a clip or according to a second embodiment, the stopper is a longitudinal tab, the discontinuous projection being a flange disposed on the outer wall of the upper housing, the free edge of the tab abutting the projection.

Enfin, on peut prévoir des dents internes qui permettent d'orienter le sens de rotation d'ouverture.Finally, it is possible to provide internal teeth which make it possible to orient the direction of opening rotation.

Par ailleurs, l'obturateur peut faire partie intégrante du boîtier supérieur à savoir l'obturateur et le boîtier supérieur peuvent être moulés d'une seule pièce. En outre, l'obturateur a une forme conique et ne comporte pas de branche axiale.Furthermore, the shutter can be an integral part of the upper case, namely the shutter and the upper case can be molded in one piece. In addition, the shutter has a conical shape and does not have an axial branch.

Sur la figure 1, on a représenté un dispositif selon l'invention en position fermée.In Figure 1, there is shown a device according to the invention in the closed position.

Le dispositif 1 est constitué d'un boîtier supérieur 2 pseudo-cylindrique d'axe de rotation xx, fermé à son extrémité supérieure 3 par un couvercle 4 et comportant à sa partie extrême inférieure 5 des orifices 6 ménagés dans la paroi. Un boîtier inférieur 7 est co-axial au boîtier supérieur 2 et il est constitué d'une partie supérieure 8, d'une partie inférieure 9 et d'une partie médiane 10. La partie supérieure est pseudo-cylindrique de révolution d'axe xx, la partie inférieure est elle aussi pseudo-cylindrique d'axe xx, le rayon r de la partie supérieure étant inférieur au rayon R de la partie inférieure 9. La partie médiane 10 est pseudo-conique. Le boîtier inférieur 7 est ouvert à ses deux extrémités 11-12 et il peut coulisser par rapport au boîtier supérieur 2.The device 1 consists of an upper pseudo-cylindrical housing 2 with an axis of rotation xx, closed at its upper end 3 by a cover 4 and comprising at its lower end 5 orifices 6 formed in the wall. A lower housing 7 is co-axial with the upper housing 2 and it consists of an upper part 8, a lower part 9 and a middle part 10. The upper part is pseudo-cylindrical with revolution of axis xx , the lower part is also pseudo-cylindrical with axis xx, the radius r of the upper part being less than the radius R of the lower part 9. The middle part 10 is pseudo-conical. The lower case 7 is open at its two ends 11-12 and it can slide relative to the upper case 2.

Le dispositif comporte, en outre, un obturateur 13 placé à l'intérieur et coopérant avec le boîtier inférieur 7. L'obturateur 13 est muni de moyens de solidarisation avec le bord libre 15 de la partie extrême inférieure 5 du boîtier supérieur 2, l'ensemble du boîtier supérieur 2 et obturateur 13 pouvant coulisser axialement entre une position de fermeture (représentée sur la figure 1) et 'une position d'ouverture maximum (représentée sur la figure 2).The device further comprises a shutter 13 placed inside and cooperating with the lower housing 7. The shutter 13 is provided with means for securing with the free edge 15 of the lower end portion 5 of the upper housing 2, l assembly of the upper housing 2 and shutter 13 which can slide axially between a closed position (shown in FIG. 1) and 'a maximum opening position (shown in Figure 2).

D'une manière connue, les moyens de solidarisation 14 de l'obturateur 13 peuvent être constitués d'une rainure 16 et d'un rebord 17 continu, le rebord 17 s'engageant dans une rainure interne 18 du boîtier inférieur tandis que la rainure 16 coopère avec des plots disposés à l'intérieur de la partie extrême inférieure 5 du boîtier supérieur 2.In a known manner, the means 14 for securing the shutter 13 may consist of a groove 16 and a continuous rim 17, the rim 17 engaging in an internal groove 18 of the lower housing while the groove 16 cooperates with studs arranged inside the lower end portion 5 of the upper housing 2.

Mais selon l'invention, on peut prévoir que le boîtier supérieur 2 et l'obturateur'13 sont constitués d'une seule pièce par exemple d'une pièce qui est moulée ou injectée, l'obturateur 13 ne comportant alors plus de rainure 16 et comportant uniquement un rebord 17 circulaire.However, according to the invention, provision can be made for the upper housing 2 and the shutter 13 to consist of a single piece, for example of a piece which is molded or injected, the shutter 13 then no longer having a groove 16 and comprising only a circular rim 17.

Ce rebord 17 constitue des moyens de fixation 18 temporaire de la partie extrême inférieure 5 de l'ensemble boîtier supérieur 2-obturateur 13 avec le boîtier inférieur 7. Ces moyens de fixation 18 temporaire, lorsqu'ils sont actifs, déterminent la fermeture et lorsqu'ils sont inactifs (voir figure 4) déterminent l'ouverture.This rim 17 constitutes temporary fixing means 18 for the lower end portion 5 of the upper 2-shutter housing assembly 13 with the lower housing 7. These temporary fixing means 18, when active, determine the closure and when 'they are inactive (see figure 4) determine the opening.

Le dispositif comporte, en outre, des moyens d'arrêt 19 du coulissement axial de l'ensemble boîtier supérieur 2 obturateur 13 par rapport au boîtier inférieur 7. Lorsque les moyens d'arrêt 19 sont actifs, ils déterminent la position d'ouverture maximum (figure 2).The device also comprises means 19 for stopping the axial sliding of the upper casing 2 assembly shutter 13 relative to the lower casing 7. When the stopping means 19 are active, they determine the maximum opening position. (figure 2).

D'une manière connue, les moyens d'arrêt 19 du coulissement axial sont constitués par le bord libre 20 supérieur de la partie supérieure du boîtier inférieur 7 et par une collerette 21 disposée sensiblement à mi-hauteur du boîtier supérieur 2.In a known manner, the means 19 for stopping the axial sliding consist of the upper free edge 20 of the upper part of the lower housing 7 and by a flange 21 disposed substantially halfway up the upper housing 2.

La collerette 21 est placée à l'extérieur du boîtier supérieur 2.The flange 21 is placed outside the upper housing 2.

Le dispositif selon l'invention est tel qu'il comporte des moyens de blocage 22 de l'emballage en position fermée (voir figures 1 et 5). Les moyens de blocage.22 ont pour fonction d'empêcher le coulissement axial du boîtier supérieur 2 par rapport au boîtier inférieur 7, tout en permettant le pivotement axial de l'ensemble boîtier supérieur 2 obturateur 13 par rapport au boîtier inférieur 7.The device according to the invention is such that it includes means 22 for locking the packaging in the closed position (see FIGS. 1 and 5). The locking means. 22 have the function of preventing the axial sliding of the upper housing 2 relative to the lower housing 7, while allowing the axial pivoting of the upper housing 2 assembly shutter 13 relative to the lower housing 7.

Selon un premier mode de réalisation de l'invention, les moyens de blocage 22 sont constitués par au moins un butoir 23 venant en butée sur la saillie circulaire 21 qui comporte au moins une discontinuité 24, le butoir 23, lors-. qu'il n'est pas en regard de la discontinuité 24 empêchant le coulissement axial.According to a first embodiment of the invention, the locking means 22 are constituted by at least one stop 23 coming into abutment on the circular projection 21 which comprises at least one discontinuity 24, the stop 23, when. that it is not opposite the discontinuity 24 preventing axial sliding.

Sur la figure 1, on voit nettement que lorsque le butoir 23 vient heurter la saillie 21, si on effectue une poussée axiale dans le sens de la flèche Fl, c'est-à-dire ayant tendance à rapprocher le boîtier supérieur 2 du boîtier inférieur 7, le butoir 23 venant s'appuyer contre la collerette 21 ne permet pas un rapprochement et donc un déplacement des deux boîtiers. Au contraire, si on effectue une rotation du boîtier supérieur 2 dans le sens de la flèche F2 ou relativement du boîtier inférieur 7 dans le sens de la flèche F3, contraire au sens de la flèche F2, le butoir 23 parvient en regard de la discontinuité 24. Or, cette discontinuité 24 ayant des dimensions correspondant au butoir 23, lorsqu'on effectue une poussée dans le sens de la flèche F1, le butoir 23 s'engage dans la discontinuité 24 et les deux boîtiers 2 et 7 peuvent se rapprocher en coulissant.In FIG. 1, it can clearly be seen that when the stopper 23 strikes the projection 21, if an axial thrust is carried out in the direction of the arrow F1, that is to say having a tendency to bring the upper housing 2 closer to the housing lower 7, the stop 23 coming to bear against the flange 21 does not allow a bringing together and therefore a displacement of the two housings. On the contrary, if the upper housing 2 is rotated in the direction of the arrow F2 or relatively of the lower housing 7 in the direction of the arrow F3, contrary to the direction of the arrow F2, the stop 23 arrives opposite the discontinuity 24. However, this discontinuity 24 having dimensions corresponding to the stop 23, when a push is made in the direction of the arrow F1, the stop 23 engages in the discontinuity 24 and the two housings 2 and 7 can be brought together in sliding.

La collerette 21 se rapproche donc du bord libre 20 et lorsque la collerette 21-vient buter contre le bord 20 du boîtier 7, les deux boîtiers 2 et 7 sont rapprochés au maximum et le dispositif est dans sa position d'ouverture maximum (figure 2 et 4).The collar 21 therefore approaches the free edge 20 and when the collar 21 abuts against the edge 20 of the housing 7, the two housings 2 and 7 are brought as close together as possible and the device is in its maximum open position (FIG. 2 and 4).

Selon un mode de réalisation de l'invention, le butoir 23 est situé sur le boîtier inférieur 7 et la saillie 21 est située sur le boîtier supérieur 2. Mais on peut aussi prévoir l'inverse, à savoir que le butoir 23 est situé sur le boîtier supérieur 2 et la saillie 21 est située sur le boîtier inférieur 7.According to one embodiment of the invention, the stopper 23 is located on the lower case 7 and the projection 21 is located on the upper case 2. But one can also provide the reverse, namely that the stopper 23 is located on the upper housing 2 and the projection 21 is located on the lower housing 7.

Selon le mode de réalisation représenté sur les figures 1, 2, 3 et 4, le butoir 23 est une patte longitudinale et la saillie discontinue 21 est une collerette disposée sur la paroi externe du boîtier supérieur 2, le bord libre 24 supérieur de la patte venant en butée sur la saillie 21.According to the embodiment shown in Figures 1, 2, 3 and 4, the stopper 23 is a longitudinal tab and the discontinuous projection 21 is a flange disposed on the outer wall of the upper housing 2, the upper free edge 24 of the tab coming into abutment on projection 21.

Sur les figures 5 et 6, on a représenté un autre mode de réalisation de la présente invention.In FIGS. 5 and 6, another embodiment of the present invention is shown.

Le dispositif représenté sur la figure 5, en position de fermeture, comporte un butoir et une saillie située dans l'espace interne compris entre la paroi externe du boîtier supérieur 2 et la paroi interne du boîtier inférieur 7.The device shown in FIG. 5, in the closed position, includes a stopper and a projection located in the internal space between the external wall of the upper housing 2 and the internal wall of the lower housing 7.

Le butoir est situé sur la paroi extérieure du boîtier supérieur 2, tandis que la saillie est située sur la paroi interne du boîtier 7.The stopper is located on the outer wall of the upper housing 2, while the projection is located on the inner wall of the housing 7.

Le butoir est un plot 24 et la saillie est un clip 25, le clip 25 étant disposé sur la paroi externe du boîtier supérieur 2.The stopper is a stud 24 and the projection is a clip 25, the clip 25 being arranged on the external wall of the upper housing 2.

Lorsqu'on effectue une rotation du boîtier supérieur 2 dans le sens de la flèche f3, par rapport au boîtier inférieur 7, le plot 24 vient en regard de l'interstice 26 du clip 25, puis lorsque l'on effectue une poussée dans le sens de la flèche fl, le plot 24 traverse l'interstice du clip 25 et on peut rapprocher le boîtier 2 supérieur du boîtier 7 inférieur.When the upper case 2 is rotated in the direction of the arrow f3, relative to the lower case 7, the stud 24 comes opposite the gap 26 of the clip 25, then when a push is made in the direction of the arrow fl, the stud 24 crosses the gap of the clip 25 and the upper housing 2 can be brought closer to the lower housing 7.

Le dispositif de sécurité constitué par les moyens de blocage 22 de l'emballage selon l'invention permet de réaliser l'obturateur 13 sur la forme d'un cône dont le sommet 27 est dirigé vers le boîtier supérieur 2. Un tel obturateur 13 ne comporte donc pas, contrairement à la technique antérieure, de pointe qui lorsque le dispositif est disposé sur un plan continu repose sur ce dernier dans le but d'empêcher une ouverture de l'emballage selon l'invention.The safety device constituted by the blocking means 22 of the packaging according to the invention makes it possible to produce the shutter 13 in the form of a cone, the apex of which is directed towards the upper housing 2. Such a shutter 13 does not Unlike the prior art, therefore, there is no advanced tip which, when the device is placed on a continuous plane, rests on the latter in order to prevent opening of the packaging according to the invention.

Enfin, on peut prévoir des dents (non représentées) qui déterminent un sens de rotation possible du boîtier supérieur 2 par rapport au boîtier inférieur 7.Finally, it is possible to provide teeth (not shown) which determine a possible direction of rotation of the upper housing 2 relative to the lower housing 7.
