Récipient à parois déformables utilisable comme poubelle jetable Container with deformable walls usable as a disposable bin
Domaine technique La présente invention concerne les récipients à parois déformables et en particulier un récipient pouvant être rendu hermétiquement clos de façon simple et pratique et pouvant être utilisé comme poubelle jetable ou aisément transportable spécialement dans le domaine des soins médicaux.Technical Field The present invention relates to containers with deformable walls and in particular a container which can be made hermetically sealed in a simple and practical manner and which can be used as a disposable bin or easily transportable especially in the field of medical care.
Etat de la techniqueState of the art
Le problème de l'élimination des déchets est un problème crucial de notre temps, qui fait de plus en plus appel à des poubelles ou conteneurs spécialisés dans lesquels les gens se débarrassent de leurs déchets de façon sélective.The problem of waste disposal is a crucial problem of our time, which increasingly uses specialized bins or containers in which people dispose of their waste selectively.
L'élimination des déchets résultant des soins médicaux tels que pansements, compresses, cotons, ... pose un problème encore plus crucial dans la mesure où elle doit être séparée de l'élimination des autres déchets, et donner lieu à des précautions supplémentaires pour éviter tout risque de contamination. Autant cette élimination peut être rendue facile en milieu hospitalier, autant elle est plus difficile lorsqu'il s'agit de soins médicaux à domicile donnés par une infirmière.The elimination of waste resulting from medical care such as dressings, compresses, cottons, etc. poses an even more crucial problem since it must be separated from the elimination of other waste, and give rise to additional precautions for avoid any risk of contamination. As much as this elimination can be made easy in a hospital environment, it is more difficult when it comes to medical care at home given by a nurse.
Il existe bien des petites poubelles dont le couvercle de fermeture est commandé par 1'appui sur une pédale. Ces poubelles peuvent effectivement servir à se débarrasser des déchets demandant des précautions particulières tels que ceux provenant des soins médicaux. Mais, elles présentent l'inconvénient de devoir être vidées lorsqu'elles sont pleines avec les inconvénients résultants (salissure, microbes...). En outre, elles sont coûteuses du fait qu'elles comportent deux parties, dont une partie mécanique, généralement métallique, assure l'ouverture du couvercle; et pas très solides du fait que le mécanisme est fragile et ne supporte pas d'être manipulé brutalement. Il existe aussi une gamme importante de poubelles en matière plastique sur le marché, destinées à l'incinération. Ces dernières comportent au moins deux parties, le couvercle et le récipient. Il y a donc deux moules à fabriquer, deux produits à gérer, d'où un coût de fabrication important entre 1'amortissement des deux outillages et les coûts fixes.There are many small trash cans whose closing lid is controlled by pressing a pedal. These bins can actually be used to get rid of waste requiring special precautions such as those from medical care. However, they have the drawback of having to be emptied when they are full with the resulting drawbacks (dirt, microbes, etc.). In addition, they are expensive because they have two parts, one of which is a mechanical part, generally metallic, which opens the cover; and not very solid because the mechanism is fragile and does not support being roughly handled. There is also a large range of plastic bins on the market, intended for incineration. The latter have at least two parts, the cover and the container. There are therefore two molds to manufacture, two products to manage, hence a significant manufacturing cost between the amortization of the two tools and the fixed costs.
Exposé de 1' inventionStatement of the invention
C'est pourquoi le but de 1'invention est de réaliser un récipient bon marché, solide, simple à utiliser et pouvant être rendu hermétiquement clos après usage.This is why the aim of the invention is to produce an inexpensive container, solid, simple to use and capable of being hermetically sealed after use.
Un autre but de 1'invention est de réaliser un récipient comme ci-dessus pouvant être utilisé comme poubelle portative, principalement pour les déchets provenant des soins médicaux.Another object of the invention is to provide a container as above which can be used as a portable trash can, mainly for medical care waste.

L'objet de l'invention est donc un récipient à parois parois déformables comprenant une première partie constituée d'une portion d'une surface de forme déterminée se terminant à son intersection avec un plan qu'elle coupe selon une courbe correspondant à une ligne de moindre épaisseur de la paroi du récipient, cette surface étant normalement fermée si elle n'était pas limitée à une portion, et une deuxième partie constituée d'une surface symétrique de la surface de forme déterminée par rapport au plan et raccordée à la première partie par la ligne de moindre épaisseur. La deuxième partie comporte une ouverture pour introduire des objets dans le récipient. Le récipient peut être rendu hermétiquement clos en exerçant une pression sur le dessus de la deuxième partie de façon à faire basculer celle-ci en contact avec la première partie par rotation par rapport à la ligne de moindre épaisseur agissant comme charnière de sorte que 1 'ouverture se trouve bouchée par la paroi de la première partie.The object of the invention is therefore a container with deformable wall walls comprising a first part consisting of a portion of a surface of determined shape ending at its intersection with a plane which it cuts according to a curve corresponding to a line. of lesser thickness of the wall of the container, this surface being normally closed if it were not limited to a portion, and a second part consisting of a surface symmetrical with the surface of shape determined with respect to the plane and connected to the first part by the line of lesser thickness.

La figure 3 est une vue en coupe partielle du récipient fermé selon la ligne A-A de la figure 2, et la figure 4 représente un mode de réalisation particulier d'un récipient utilisant les principes de l' invention.Figure 3 is a partial sectional view of the closed container along line A-A of Figure 2, and Figure 4 shows a particular embodiment of a container using the principles of the invention.
Description détaillée de 1 'invention La figure 1 représente un récipient à parois déformables en matière plastique pouvant être utilisé dans diverses applications et en particulier en tant que poubelle portative et bon marché pour l'élimination des déchets provenant des soins médicaux. Le corps du récipient 10 destiné à recevoir les déchets est prolongé vers le haut par une première partie 12 en forme de calotte sphérique s'arrêtant à la ligne 16 se trouvant à 1' intersection de la calotte sphérique avec un plan. La ligne 16 correspond à une moindre épaisseur de la paroi du récipient de façon à fonctionner comme une charnière comme on va le voir.DETAILED DESCRIPTION OF THE INVENTION FIG. 1 represents a container with deformable walls made of plastic material which can be used in various applications and in particular as a portable and inexpensive bin for the disposal of waste from medical care. The body of the container 10 intended to receive the waste is extended upwards by a first part 12 in the form of a spherical cap ending at the line 16 located at the intersection of the spherical cap with a plane. Line 16 corresponds to a lesser thickness of the wall of the container so as to function as a hinge as will be seen.
La partie 14 de dessus du récipient a également la forme d'une calotte sphérique symétrique de la calotte sphérique correspondant à la partie 12. Ainsi, lorsqu'on exerce une pression au sommet de la partie 14, sa paroi se déforme tout en opposant une force qui tend à s'opposer à la pression exercée. Lorsque la partie 14 est suffisamment déformée vers le bas, elle bascule d'un seul coup vers le bas en utilisant la ligne 16 de moindre épaisseur comme charnière, pour venir se loger à l'intérieur de la partie concave 12. Ce basculement est plus facile si la partie convexe 14 est légèrement plus petite en hauteur que la partie concave 12; mais ceci n'est pas obligé dans la mesure où les parois en matière plastique sont suffisamment déformables pour que la partie 14 vienne se plaquer dans la partie 12 de même dimension. La partie supérieure 12 comporte une ouverture 18 par laquelle on peut introduire les déchets. Lorsque la partie 14 est plaquée à 1'intérieur de la partie concave 12, l'ouverture 18 se trouve donc obturée par la paroi 12 et le récipient est donc hermétiquement clos tel qu'illustré sur la figure 2.The top part 14 of the container also has the shape of a spherical cap symmetrical with the spherical cap corresponding to the part 12. Thus, when a pressure is exerted on the top of the part 14, its wall deforms while opposing a force which tends to oppose the pressure exerted. When part 14 is enough deformed downward, it swings down suddenly using the line 16 of lesser thickness as a hinge, to come to be housed inside the concave part 12. This tilting is easier if the convex part 14 is slightly smaller in height than the concave part 12; but this is not obligatory insofar as the plastic walls are sufficiently deformable for the part 14 to be pressed against the part 12 of the same dimension. The upper part 12 has an opening 18 through which the waste can be introduced. When the part 14 is pressed inside the concave part 12, the opening 18 is therefore closed off by the wall 12 and the container is therefore hermetically sealed as illustrated in FIG. 2.
Symétriquement à l'ouverture 18 par rapport au plan de la ligne 16, la partie 12 comporte une protubérance 22 vers l'extérieur. L'utilité de la protubérance 22 est de verrouiller le récipient. Par le même effet que lors de la fermeture du récipient, il suffit d'exercer une pression sur la protubérance 22 pour la faire basculer à 1 ' intérieur du récipient. Du fait que la protubérance 22 est symétrique de l'ouverture 18 par rapport au plan de la ligne 16, la protubérance 22 rentre dans l'ouverture 18 comme illustré sur la figure 3 qui est une coupe du récipient fermé selon la ligne A-A de la figure 2. La paroi 26 de la partie supérieure épousant la forme de la paroi 28 de la partie concave, est alors verrouillée par la protubérance rentrée à 1 ' intérieur du récipient. Le récipient illustré sur les figures 1, 2 et 3 est généralement en matière plastique telle que du polyéthylène, ou de la matière plastique recyclée. Mais il pourrait être également en métal suffisamment souple pour que les parois soient déformables. Le récipient peut avoir n'importe quelles dimensions et la partie 10 peut être plus ou moins profonde, quitte à être réduite à rien de sorte que le récipient soit formé de deux calottes sphériques symétriques.Symmetrically at the opening 18 relative to the plane of the line 16, the part 12 has a protrusion 22 outwards. The utility of the protrusion 22 is to lock the container. By the same effect as when the container is closed, it suffices to exert pressure on the protuberance 22 to cause it to tilt inside the container. Because the protrusion 22 is symmetrical with the opening 18 relative to the plane of the line 16, the protrusion 22 enters the opening 18 as illustrated in FIG. 3 which is a section through the closed container along line AA of the Figure 2. The wall 26 of the upper part matching the shape of the wall 28 of the concave part, is then locked by the protrusion retracted 1 inside the container. The container illustrated in FIGS. 1, 2 and 3 is generally made of plastic material such as polyethylene, or recycled plastic material. But it could also be made of metal which is flexible enough for the walls to be deformable. The container can have any size and the part 10 can be more or less deep, even if it is reduced to nothing so that the container is formed by two symmetrical spherical caps.
Un récipient de petite taille peut être utilisé comme poubelle portative jetable. Ainsi, une infirmière donnant des soins à domicile y jettera les pansements, bandes, tissus... ayant servi pour son patient et fermera ensuite le récipient comme il a été décrit précédemment avant de le jeter, donc en évitant tout risque de contamination. Mais le récipient peut être de dimensions moyennes et servir plusieurs fois. C'est pour cette raison qu'un élément de préhension 20 est prévu au sommet de la partie 14 comme illustré sur la figure 1. Ainsi, lorsque l'infirmière, par exemple, voudra se servir de la poubelle une deuxième fois après l'avoir fermée, il suffit qu'elle saisisse l'élément 20 et qu'elle tire vers le haut pour que la partie 14 revienne dans sa position initiale.A small container can be used as a portable disposable bin. Thus, a nurse giving care at home will throw there the dressings, bands, fabrics ... having served for his patient and will then close the container as it was described previously before throwing it away, therefore avoiding any risk of contamination. However, the container can be of medium size and serve several times. It is for this reason that a gripping element 20 is provided at the top of the part 14 as illustrated in FIG. 1. Thus, when the nurse, for example, wants to use the trash a second time after the having closed, it suffices that it grips the element 20 and that it pulls upwards so that the part 14 returns to its initial position.
De même façon, la protubérance 22 peut être pourvue d'un élément de préhension 24 (voir figures 2 et 3) qu'il suffira de tirer pour déverrouiller le récipient.Similarly, the protrusion 22 can be provided with a gripping element 24 (see Figures 2 and 3) that will suffice to pull to unlock the container.
Même si le récipient est appelé à ne servir qu'une fois, les éléments de préhension 20 et 24 ont leur utilité. En effet, le transport étant une partie importante des frais de revient d'un produit, il est préférable que le produit avant usage soit le moins encombrant possible. Avec le système de l'invention, il est plus économique de transporter les récipients en position fermée et de les rendre opérationnels par traction sur l'élément de préhension 24 puis sur l'élément de préhension 20 au moment de l'usage.Even if the container is to be used only once, the gripping elements 20 and 24 are useful. In fact, transport being an important part of the cost price of a product, it is preferable that the product before use is as compact as possible. With the system of the invention, it is more economical to transport the containers in the closed position and to make them operational by pulling on the gripping element 24 then on the gripping element 20 at the time of use.
Dans un mode particulier de 1'invention illustré sur la figure 4, le récipient se présente comme une suite de combinaison de calottes sphériques convexe et concave. Toute combinaison ou ensemble a un diamètre qui est inférieur à celui de la combinaison de dessous et qui est supérieur à celui de la combinaison de dessus. Ainsi, l'ensemble 30 est plus petit que l'ensemble 32, lui-même plus petit que l'ensemble 34, lui-même plus petit que l'ensemble 36. Si on applique le principe décrit en référence à la figure 1 en exerçant une pression sur le sommet de l'ensemble 30, la partie convexe supérieure entre dans la partie concave symétrique; puis cet ensemble concave en même temps que la partie convexe de 1 'ensemble 32 basculant vers le bas, forme un ensemble concave épousant la forme intérieure de la partie concave de l'ensemble 32.... et ainsi de suite. En phase finale, le récipient a donc la forme d'un bol avec chacune des parties (convexe ou concave) encastrée dans la partie inférieure.In a particular embodiment of the invention illustrated in FIG. 4, the container is presented as a series of combinations of convex and concave spherical caps. Any combination or set has a diameter which is less than that of the bottom suit and which is greater than that of the top suit. Thus, the set 30 is smaller than the set 32, itself smaller than the assembly 34, itself smaller than the assembly 36. If the principle described with reference to FIG. 1 is applied by applying pressure to the top of the assembly 30, the upper convex part enters the symmetrical concave part; then this concave assembly at the same time as the convex part of the assembly 32 tilting downwards, forms a concave assembly conforming to the internal shape of the concave part of the assembly 32 .... and so on. In the final phase, the container therefore has the shape of a bowl with each of the parts (convex or concave) embedded in the lower part.
Le mode de réalisation ci-dessus présente un avantage considérable sur tout autre récipient de même utilité dans la mesure où il est transportable sous une forme extrêmement réduite par rapport à sa forme utilisable. Donc, avec ce mode de réalisation, au coût de fabrication réduit s'ajoute un faible coût de transport.The above embodiment has a considerable advantage over any other container of the same utility insofar as it is transportable in an extremely reduced form compared to its usable form. Therefore, with this embodiment, the reduced manufacturing cost is added a low transport cost.
Bien que les modes de réalisation décrits ici concernent des récipients dont les deux parties 12 et 14 sont des calottes sphériques, il est évidemment possible d'utiliser des formes différentes (paraboloïde, cône... ) pour obtenir le même résultat, la condition restant que les deux parties sont symétriques par rapport à un plan dans lequel se situe la ligne de moindre épaisseur jouant le rôle de charnière.Although the embodiments described here relate to containers, the two parts 12 and 14 of which are spherical caps, it is obviously possible to use different shapes (paraboloid, cone, etc.) to obtain the same result, the condition remaining that the two parts are symmetrical with respect to a plane in which is located the line of least thickness playing the role of hinge.
Du fait de sa géométrie, et en particulier en utilisant des formes sensiblement sphériques, le mode de fabrication préféré consiste à réaliser le récipient en matière plastique d'une seule pièce par le procédé classique d'extrusion-soufflage, ou d'injection-soufflage. Ainsi, il suffira d'un seul moule contrairement aux procédés de fabrication antérieurs de récipients servant à l'élimination des déchets qui nécessitent au moins deux moules. On voit donc que le récipient qui vient d'être décrit présente de nombreux avantages pouvant être résumés par: un coût de fabrication faible (récipient d'une seule pièce), un encombrement réduit, une facilité et une simplicité d'utilisation, une rapidité de manipulation et une bonne étanchéité. Due to its geometry, and in particular by using substantially spherical shapes, the preferred method of manufacture consists in making the plastic container in one piece by the conventional extrusion blow molding or injection blow molding process. . Thus, a single mold will suffice, unlike previous methods of manufacturing containers used for the elimination of waste which require at least two molds. It can therefore be seen that the container which has just been described has numerous advantages which can be summarized by: a low manufacturing cost (container of a single piece), reduced dimensions, ease and simplicity of use, speed of handling and good sealing.
