Description
Dispositif à sécurité pour la fermeture de conteneurs devant etre stérilisés.Safety device for closing containers to be sterilized.
La présente invention concerne un dispositif à sécurité pour réaliser la fermeture de conteneurs devant être stérilisés. The present invention relates to a safety device for closing containers to be sterilized.
On sait que de nombreux dispositifs et instruments chirurgicaux doivent être stérilisés et maintenus à l'état stérile jusqu'3 leur utilisation. Pour cela, il est souvent commode d'inclure ces dispositifs et instruments dans des conteneurs que l'on pourra stériliser extérieurement et intérieurement, notamment à la vapeur, grâce en particulier pour la stérilisation intérieure au fait que lesdits conteneurs sont munis de perforations avec filtres spéciaux. It is known that many surgical devices and instruments must be sterilized and kept sterile until used. For this, it is often convenient to include these devices and instruments in containers that can be sterilized externally and internally, in particular with steam, thanks in particular for internal sterilization to the fact that said containers are provided with perforations with filters special.
Ces conteneurs sont très généralement constitués d'un corps et d'un couvercle, la liaison entre le sommet des parois dudit corps et le pourtour du fond du couvercle étant rendue étanche grâce à l'interposition d'un ,oint, relativement épais de préférence, réalisé en un matériau résistant à la température. These containers very generally consist of a body and a cover, the connection between the top of the walls of said body and the periphery of the bottom of the cover being sealed by the interposition of an, anointed, relatively thick preferably , made of a temperature resistant material.
L'invention consiste dans un dispositif permettant de fermer, à l'état étanche, de tels conteneurs, de maintenir cet état étanche pendant la durée de stockage dudit conteneur et, de préférence, de présenter une sécurité contre toute fausse manoeuvre intempestive tendant à ouvrir ledit conteneur. The invention consists in a device making it possible to close, in a sealed state, such containers, to maintain this sealed state during the storage time of said container and, preferably, to present a security against any untimely false maneuver tending to open. said container.
Le dispositif selon l'invention utilise pour la fermeture de conteneurs stérilisables formés d'un corps, de préférence de forme parallélépipédique,composés d'un fond et de parois latérales et d'un couvercle de forme correspondant à celle dudit corps qui comporte également un fond muni sur le pourtour de sa face interne d'un joints de préférence relativement épais, et des parois latérales, ledit couvercle s'emboitant autour dudit fond, ledit dispositif est caractérisé en ce qu'il comporte
- sur la face extérieure d'une des parois latérales dudit fond ou dudit couvercle, un axe sur lequel vient se fixer et autour duquel peut tourner une came de forme générale circulaire et comportant, sur sa face interne, un rebord en forme de spire disposé à partir d'une échancrure
- et sur la face extérieure d'une des parois latérales correspondates dudit couvercle ou dudit fond, d'un pion,
- ladite came et ledit plor étant disposés de telle sorte que, lorsque le couvercle est posé sur le fond, le pion vienne s'engager dans l'échancrure de la came et que, par rotation de ladite came, le pion s 'appuyant sur ledit rebord de ladite came provoque un rapprochement dudit couvercle avec ledit fond et > par-là même, la fermeture du conteneur.The device according to the invention uses for the closure of sterilizable containers formed of a body, preferably of parallelepiped shape, composed of a bottom and side walls and a cover of shape corresponding to that of said body which also comprises a bottom provided around its inner face with preferably relatively thick seals, and side walls, said cover fitting around said bottom, said device is characterized in that it comprises
- on the outer face of one of the side walls of said bottom or of said cover, an axis on which is fixed and around which a cam of generally circular shape can rotate and comprising, on its internal face, a rim in the form of a coil arranged from a notch
- and on the outer face of one of the corresponding side walls of said cover or said bottom, of a pin,
- Said cam and said plor being arranged so that, when the cover is placed on the bottom, the pin comes to engage in the notch of the cam and that, by rotation of said cam, the pin pressing on said edge of said cam causes said cover to approach said bottom and> thereby, the closure of the container.
I1 va de soi que la came peut être portée soit par le fond, soit par le couvercle du conteneur Cependant, on préfère, en général, que la came soit portée par une paroi latérale du fond du conteneur. It goes without saying that the cam can be carried either by the bottom or by the lid of the container. However, it is generally preferred that the cam is carried by a side wall of the bottom of the container.
Le rebord en forme de spire qui constitue la face interne de la came a généralement une hauteur sensiblement constante mais le pas de la spire, c'est-8-dire la différence de distance des deux extrémités dudit rebord en forme de spire avec l'axe de rotation de la came, peut être variable selon les modèles et est adapté à l'épaisseur et à flexibilité d joint situé au fond du couvercle. The whorl-shaped rim which constitutes the internal face of the cam generally has a substantially constant height but the pitch of the whorl, that is to say the difference in distance between the two ends of said whorl-shaped rim with the axis of rotation of the cam, can be variable depending on the model and is adapted to the thickness and flexibility of the seal located at the bottom of the cover.
Ce que l'on appelle ici la face interne de la came est celle qui fait face à la paroi latérale du fond ou du couvercle. What is called here the internal face of the cam is that which faces the side wall of the bottom or of the cover.
Le rebord en forme de spire ne fait pas un tour entier mais est interrompu, sur une certaine largeur, pour ménager une échancrure suffisante pour le passage du pion. The spiral-shaped rim does not make an entire turn but is interrupted, over a certain width, to provide a notch sufficient for the passage of the pawn.
Le dispositif selon l'invention présente divers avantages parmi lesquels on peut citer les suivants:
- lorsque le joint, disposé entre le fond et le couvercle, est neuf il permettra un certain serrage par rotation de la came, c'est-a-dire que le pion parcourra une certaine longueur du rebord en forme de spire lors de la fermeture
- au fur et à mesure que le joint s'usera pour obtenir un serrage identique il faudra que le pion parcourt une longueur plus grande du rebord en forme de spire mais ceci sera très facile à réaliser en exerçant sur la came une force sensiblement constante
- lorsque le joint sera trop usé, donc considéré comme hors d'usage, le pion pourra parcourir tout le tour du rebord en forme de spire c'est-à-dire qu'il reviendra dans l'échancrure et que la fermeture n'aura pas lieu.The device according to the invention has various advantages, among which the following can be cited:
- when the seal, arranged between the bottom and the cover, is new it will allow a certain tightening by rotation of the cam, that is to say that the pin will travel a certain length of the rim in the form of a coil when closing
- as the joint wears down to obtain identical tightening, the pin must travel a greater length of the spiral-shaped rim, but this will be very easy to achieve by exerting on the cam a substantially constant force
- when the seal is too worn, therefore considered to be out of use, the pin can travel all around the edge in the form of a turn, that is to say that it will return in the notch and that the closure does not will not take place.
Mais le dispositif selon l'invention peut être complété par un dispositif complémentaire de sécurité qui évite toute fausse manoeuvre c'est- -dire toute ouverture intempestive du conteneur. However, the device according to the invention can be completed by an additional safety device which avoids any false maneuver, that is to say any untimely opening of the container.
Ce dispositif est caractérisé en ce que l'axe autour duquel tourne ladite came est constitué par un manchon intermédiaire, solidaire de la paroi latérale du fond ou du couvercle du conteneur, et comportant un alésage permettant la traversée de ladite paroi et, vers l'extérieur de ladite paroi, un trou taraudé dont le filetage est inversé par rapport au sens d'enroulement du rebord en forme de spire et en ce que l'on dispose d'une vis de blocage comportant une extrémité susceptible de pénétrer dans ledit alésage, une partie intermédiaire filetée venant se visser dans ledit trou taraudé et une tête venant appuyer sur la face extérieure de ladite came lorsque ladite vis de blocage est serrée, ladite tête comportant des moyens spécifiques pour effectuer le serrage et le desserrage de ladite vis de blocage. This device is characterized in that the axis around which said cam rotates is constituted by an intermediate sleeve, integral with the side wall of the bottom or of the container cover, and comprising a bore allowing the passage of said wall and, towards the outside of said wall, a threaded hole whose thread is reversed with respect to the winding direction of the spiral-shaped rim and in that there is a locking screw having an end capable of penetrating said bore, a threaded intermediate part coming to be screwed into said tapped hole and a head coming to press on the external face of said cam when said locking screw is tightened, said head comprising specific means for tightening and loosening said locking screw.
On comprend que, lorsque le conteneur a été fermé, comme expliqué précédemmenty par coopération entre le pion et la came et que la vis de blocage a été serrée avec une clé adéquate agissant sur ladite vis, si par inadvertance quelqu'un, ne disposant. It is understood that, when the container has been closed, as explained above by cooperation between the pin and the cam and that the locking screw has been tightened with an adequate key acting on said screw, if someone inadvertently does not have it.
pas de ladite clé, rente d'ouvrir la boSte, cette action sur la came aura tendance, par frottement, à entraîner la vis de blocage et, compte tenu du pas de vis inverse de ladite vis dans ledit manchon intermédiaire, à serrer ladite vis de blocage donc à bloquer ladite came.pitch of said key, rent to open the box, this action on the cam will tend, by friction, to drive the locking screw and, taking into account the reverse pitch of said screw in said intermediate sleeve, to tighten said screw blocking therefore to block said cam.
L'invention sera mieux comprise en 8@ se référant à l'exemple non limitatif ci-après qui décrit un mode de mise en oeuvre de l'invention. The invention will be better understood in 8 @ referring to the nonlimiting example below which describes an embodiment of the invention.
