Description

La présente invention a pour objet un dispositif d'écoulement du contenu d'un récipient.The present invention relates to a device for draining the contents of a container.

Plus particulièrement, elle a pour objet un dispositif d'écoulement du contenu stérile d'un récipient, dans des conditions de propreté bactériologique.More particularly, it relates to a device for discharging the sterile content of a container, under conditions of bacteriological cleanliness.

Ce dispositif peut avantageusement être utilisé quand il est posé notamment sur les ouvertures de récipients contenant des préparations riches en principes nutritifs destinées par exemple, aux malades nourris par sonde ou «per os». De telles préparations doivent être maintenues à l'abri de la contamination bactérienne, après l'ouverture du récipient.This device can advantageously be used when it is placed in particular on the openings of containers containing preparations rich in nutritive principles intended for example, for patients fed by tube or "per os". Such preparations should be kept away from bacterial contamination after the container has been opened.

On connait déjà de nombreux dispositifs pouvant être utilisés pour l'écoulement du contenu d'un récipient.We already know many devices that can be used for the flow of the contents of a container.

Le dispositif de l'invention peut encore être caractérisé par les points suivants:

  • - il comporte au moins deux rangées de nervures parallèles entre elles et lesdites nervures des différentes rangées sont disposées en chicanes les unes par rapport aux autres;
  • - la dépression de la base a une forme géométrique, dotée de parties amincies qui rendent cette dépression susceptible d'être déformée et aplatie d'une manière irréversible.
  • - la dépression de la base a la forme d'une pyramide tronquée à section trapézoïdale, dont les arêtes sont arrondies et la paroi au niveau de ces arêtes est amincie, ou la forme d'un cône circulaire ou elliptique tronqué;
The device of the invention can also be characterized by the following points:
  • - It comprises at least two rows of ribs parallel to each other and said ribs of the different rows are arranged in baffles with respect to each other;
  • - The depression of the base has a geometric shape, with thinned parts which make this depression liable to be deformed and flattened in an irreversible manner.
  • - The depression of the base has the shape of a truncated pyramid with a trapezoidal section, the edges of which are rounded and the wall at the level of these edges is thinned, or the shape of a truncated circular or elliptical cone;

Ainsi le brevet américain 2 844 289 décrit un dispositif d'écoulement destiné à une ouverture tubulaire et qui est sous forme d'un bouchon exécuté comme un corps tubulaire. Il comporte une dépression de forme circulaire qui est constituée par un évasement vers l'extérieur, à paroi amincie, qui fait le tour de la dépression et qui forme une jupe. Cette jupe se prolonge en une collerette périphérique, exécutée sous forme d'une jante circulaire, laquelle jante est dessinée de manière incurvée, pour qu'elle puisse coopérer avec le rebord de l'ouverture tubulaire d'un récipient et établir un contact étanche avec ce dernier.Thus, US Pat. No. 2,844,289 describes a flow device intended for a tubular opening and which is in the form of a plug executed like a tubular body. It comprises a depression of circular shape which is constituted by a widening towards the outside, with a thinned wall, which goes around the depression and which forms a skirt. This skirt extends into a peripheral flange, executed in the form of a circular rim, which rim is drawn in a curved manner, so that it can cooperate with the rim of the tubular opening of a container and establish a tight contact with this last.

Néanmoins peu de ces dispositifs peuvent satisfaire simultanément aux conditions de propreté bactériologique exigées, tout en gardant l'avantage d'une manipulation aisée lors de leur mise en place et de leur utilisation.However, few of these devices can simultaneously satisfy the required bacteriological cleanliness conditions, while retaining the advantage of easy handling during their installation and use.

Afin de remédier à ces inconvénients et afin de pouvoir garantir la propreté bactériologique du contenu d'un récipient pendant toute la durée d'écoulement de son contenu, la Société demanderesse a mis au point le dispositif de la présente invention.In order to remedy these drawbacks and in order to be able to guarantee the bacteriological cleanliness of the contents of a container throughout the duration of the flow of its contents, the Applicant Company has developed the device of the present invention.

Les avantages du présent dispositif sont obtenus grâce à sa conception et à l'agencement de ses éléments.The advantages of the present device are obtained thanks to its design and the arrangement of its elements.

Selon l'invention, le dispositif d'écoulement du contenu stérile d'un récipient muni d'un couvercle assurant, en fonction, la propreté bactériologique dudit contenu, étant adaptable à une ouverture pratiquée dans ledit couvercle, ou présente sur ledit récipient, ou faisant corps avec celui-ci, et étant exécuté sous forme d'un bouchon en matière plastique déformable comprenant un orifice de vidange doté d'un bec d'écoulement et une base munie d'une dépression qui, grâce à ses parois amincies, peut par pression se déformer et s'aplatir, ledit bouchon étant, en outre doté d'un moyen qui lors de l'aplatissement vient s'enclencher sur le récipient et maintient en place l'ensemble, est caractérisé en ce que:

  • - the depression of the base has such a geometric shape and is endowed with thinned parts such that it is capable of being irreversibly deformed,
  • - at least one side of the edge of this depression such as that situated opposite the clip comprises a retaining lug arranged on a wall and extending opposite the depression,
  • - during the flattening of the depression, its walls also flatten and rotate said lug so as to engage it under the cover to maintain it,
  • -and the flat part of the base which surrounds the depression comprises on its surface, oriented opposite the flow spout, at least one row of discontinuous ribs, intended to cooperate with a seal, disposed between said base and the cover , or intended to cooperate with the lid of the container, so as to ensure, after the closure of said container, simultaneously impermeability to the liquid contained therein and permeability to air,
  • - the thinned parts of the walls of the depression are in the form of grooves;
  • - The depression retaining lug is arranged so as to form an obtuse angle with the wall of the depression at the edge of which it is placed;
  • - It has four retaining pins arranged on the walls of the depression;
  • -the base has a retaining clip;
  • - It is deprived of the joint and the rows of ribs are made of an elastically deformable material different from that of which the base is made, and are applied to the surface of the part of the base which surrounds the depression;

Le dispositif de l'invention peut encore être illustré par les modes d'éxécution qui suivent:

  • - il est éxécuté notamment en une matière plastique telle que le polyéthylène, le polypropylène, le chlorure de polyvinyle ou le téflon;
  • - la dépression de la base peut avoir tout autre forme géométrique permettant d'assurer l'aplatissement de ladite dépression; elle peut aussi avoir la forme d'une pyramide triangulaire tronquée, d'un cylindre, d'un parallélépipède ou d'un prisme;
  • - une fois fabriqué, il peut-être conditionné stérilement, notamment dans des sachets, et stérilisé au moyen par exemple d'oxyde d'éthylène ou par irradiation;
  • - le joint dans le cas où il est présent est exécuté en une matière élastiquement déformable, tel qu'un latex naturel ou synthétique;
  • - le clip de sécurité est disposé à l'extrémité la moins large du dispositif de l'invention;
  • - les ergots de maintien sont disposés dans la partie la plus large du dispositif de l'invention;
  • - le bec d'écoulement sur lequel doit être relié un conduit comporte à son extrémité un demi-pas ou un pas de vis sur lequel se visse un embout sous forme d'écrou, de manière à assurer une communication étanche entre le dispositif de l'invention et le conduit.
The device of the invention can also be illustrated by the following modes of execution:
  • - It is executed in particular in a plastic material such as polyethylene, polypropylene, polyvinyl chloride or Teflon;
  • - The depression of the base can have any other geometric shape making it possible to flatten said depression; it can also have the shape of a truncated triangular pyramid, a cylinder, a parallelepiped or a prism;
  • - Once manufactured, it can be sterile packaged, in particular in sachets, and sterilized using, for example, ethylene oxide or by irradiation;
  • - the joint, if present, is executed in an elastically deformable material, such as a natural or synthetic latex;
  • - The safety clip is arranged at the narrower end of the device of the invention;
  • - The retaining lugs are arranged in the widest part of the device of the invention;
  • - The outlet spout to which a conduit must be connected has at its end a half-pitch or a pitch of screw on which is screwed a nozzle in the form of a nut, so as to ensure tight communication between the device of the invention and the conduit.

Les dimensions du dispositif de l'invention sont choisies en fonction des dimensions de l'ouverture du récipient qu'il ferme.The dimensions of the device of the invention are chosen according to the dimensions of the opening of the container which it closes.

Dans le cas où le dispositif ne dispose pas du joint et où les rangées des nervures sont appliquées sur la surface précitée de la partie de la base qui entoure la dépression, lesdites nervures sont éxécutées en un matériau suffisament déformable tel que le latex naturel ou synthétique, et l'espacement des nervures entre elles et le nombre des rangées sont choisis de manière à assurer à la fermeture du récipient, l'imperméabilité au liquide contenu et la perméabilité à l'air.In the case where the device does not have the seal and where the rows of ribs are applied to the aforementioned surface of the part of the base which surrounds the depression, said ribs are made of a sufficiently deformable material such as natural or synthetic latex , and the spacing of the ribs between them and the number of rows are chosen so as to ensure, when the container is closed, the impermeability to the liquid contained and the air permeability.

On peut envisager également que le dispositif soit doté d'un moyen supplémentaire concourant à la propreté bactériologique du contenu du récipient lors de l'utilisation. A cet effet, on peut disposer en plus, par exemple, un filtre stérilisant entre le joint et la surface de la base doté des rangées de nervures.It is also conceivable that the device is provided with an additional means contributing to the bacteriological cleanliness of the contents of the container during use. For this purpose, in addition, for example, a sterilizing filter can be arranged between the seal and the surface of the base provided with rows of ribs.

On peut envisager également que le joint assume simultanément le rôle d'un joint et d'un filtre stérilisant. Dans ce cas, il doit être exécuté en un matériau simultanément perméable à l'air imperméable au liquide contenu dans le récipient.It is also conceivable that the seal simultaneously assumes the role of a seal and a sterilizing filter. In this case, it must be made of a material simultaneously permeable to air impermeable to the liquid contained in the container.

Lors de l'utilisation du dispositif de la présente invention on procède en premier lieu à l'ouverture du récipient (10).When using the device of the present invention, the container (10) is opened first.

Cette ouverture peut se faire par exemple par l'arrachement d'une partie du couvercle (9). Une fois l'ouverture pratiquée dans le récipient (10), on procède à la mise en place du dispositif selon l'invention, préalablement libéré de son conditionnement. Pour le mettre en place, on introduit premièrement le clip de sécurité (11) et les ergots de maintien (7) dans l'ouverture pratiquée, et applique la base (1 ) du dispositif contre le couvercle (9) du récipient (10).This opening can be done for example by tearing off part of the cover (9). Once the opening has been made in the container (10), the device according to the invention is put in place, previously released from its packaging. To set it up, first insert the safety clip (11) and the retaining pins (7) into the opening, and apply the base (1) of the device against the cover (9) of the container (10) .

Il suffit ensuite de faire pression sur le renforcement (14) du fond (5) de la dépression (2), pour que la dépression (2) s'aplatisse et que l'ensemble se déforme.It then suffices to apply pressure to the reinforcement (14) of the bottom (5) of the depression (2), so that the depression (2) becomes flat and the assembly is deformed.

Cette déformation est rendue possible grâce aux parites amincies (4) des parois (3) de la dépression (2).This deformation is made possible by the thinned parities (4) of the walls (3) of the depression (2).

Sous la pression exercée comme indiqué ci- dessus, lors de la déformation de la dépression (2), celle-ci s'aplatit donc jusqu'à ce que son fond (5) vienne se placer au même niveau que le reste de la base (1).Under the pressure exerted as indicated above, during the deformation of the depression (2), it therefore flattens until its bottom (5) comes to be placed at the same level as the rest of the base. (1).

Au cours de cette déformation, les parois (3) se rapprochent du plan horizontal du reste de la base (1). Ce faisant, et comme les parois comportent les ergots de maintien (7), l'orientation de ces derniers se trouve modifiée au fur et à mesure de la déformation de la dépression (2).During this deformation, the walls (3) approach the horizontal plane from the rest of the base (1). In doing so, and as the walls include the retaining lugs (7), the orientation of the latter is changed as the depression (2) is deformed.

En effet, comme les parois (3) s'aplatissent, elles déplacent simultanément les extrémités des sommets des ergots (7) de manière à les faire pivoter sous le couvercle (9) et ainsi à les enclan- cher sous le couvercle (9).Indeed, as the walls (3) flatten, they simultaneously move the ends of the tops of the lugs (7) so as to pivot them under the cover (9) and thus to engage them under the cover (9) .

Les ergots (7) enclenchés sous le couvercle (9), assurent le maintien en place du dispositif de l'invention.The pins (7) engaged under the cover (9), keep the device of the invention in place.

En fait, une fois le dispositif de l'invention mis en place, il est presque impossible en tirant sur le bec d'écoulement (12) de faire revenir le dispositif à sa position initiale, sans faire céder lesdites parois (3) et donc lacher la prise aux ergots de maintien (7).In fact, once the device of the invention in place, it is almost impossible by pulling on the flow spout (12) to return the device to its initial position, without causing said walls (3) and therefore release the plug from the retaining pins (7).

Lors de la mise en plan du dispositif, les rangées (16) des nervures (6) déforment le joint (15) juste suffisament pour garantir le bon contact entre lesdites nervures (6) et ledit joint (15).When the device is planed, the rows (16) of the ribs (6) deform the seal (15) just enough to guarantee good contact between said ribs (6) and said seal (15).

Lors de cette déformation du joint (15), le degré de compression dudit joint (15) n'est pas uniforme sur toute sa surface. En effet, la compression est beaucoup plus grande aux endroits où les nervures (6) compriment ledit joint (15) qu'aux endroits situés entre les nervures (6).During this deformation of the seal (15), the degree of compression of said seal (15) is not united forms over its entire surface. Indeed, the compression is much greater at the places where the ribs (6) compress said seal (15) than at the places located between the ribs (6).

Néanmoins, la compression est suffisament forte pour créer le contact intime entre le joint et la partie (1') de la base (1 ). Ce contact, compte tenu également du fait que lesdites nervures des différentes rangées sont disposées en chicanes les unes par rapport aux autres, empêche le liquide contenu dans le récipient de traverser les chicanes des nervures et de provoquer des fuites, d'autant plus que le dispositif de la présente invention est notamment destiné aux liquides plus ou moins visqueux, comme c'est le cas des préparations nutritives.However, the compression is strong enough to create intimate contact between the joint and the part (1 ') of the base (1). This contact, also taking into account the fact that said ribs of the different rows are arranged in baffles with respect to each other, prevents the liquid contained in the container from passing through the baffles of the ribs and causing leaks, all the more so as the The device of the present invention is in particular intended for more or less viscous liquids, as is the case with nutritive preparations.

Si un tel liquide parvient à s'infiltrer dans la première rangée, les nervures des rangées suivantes étant disposées en chicanes ne lui permettent pas de traverser toutes les rangées.If such a liquid manages to seep into the first row, the ribs of the following rows being arranged in baffles do not allow it to cross all the rows.

En ce qui concerne la perméabilité à l'air du dispositif de l'invention mis en place, le récipient une fois retourné et l'écoulement du liquide du récipient commencé, il se crée à l'intérieur du dispositif une dépression. Cette dépression grandit avec l'écoulement du liquide et fait appel d'air.With regard to the air permeability of the device of the invention installed, the container once turned over and the flow of the liquid from the container started, a vacuum is created inside the device. This depression increases with the flow of liquid and draws in air.

Cette force d'aspiration combinée avec la compression mesurée exercée sur le joint (15) par les rangées (16) des nervures (6), et variable selon les endroits, permet à l'air de traverser le passage pour pénétrer entre lesdites nervures (6) et, en cheminant entre les rangées (16), de pénétrer par l'ouverture du couvercle (9), dans le récipient.This suction force combined with the measured compression exerted on the seal (15) by the rows (16) of the ribs (6), and variable depending on the location, allows air to pass through the passage to penetrate between said ribs ( 6) and, moving between the rows (16), to penetrate through the opening of the cover (9), into the container.

Par la même occasion, l'air aspiré empêche simultanément le liquide de s'infiltrer profondément entre les rangées (16).At the same time, the air drawn in simultaneously prevents the liquid from seeping deeply between the rows (16).

Grâce à l'agencement du dispositif de l'invention, le liquide peut s'écouler du récipient normalement, sans que des fuites se produisent.Thanks to the arrangement of the device of the invention, the liquid can flow from the container normally, without leakage occurring.

Une fois donc le dispositif de l'invention mis en place, on relie le bec d'écoulement (12) à un conduit que l'on visse sur le demi-pas de vis (13) dudit bec d'écoulement (12), puis on retourne le récipient (10) de 180° et suspend l'ensemble à une potence.Once the device of the invention has been put in place, the flow spout (12) is connected to a duct which is screwed onto the half-pitch of the screw (13) of said flow spout (12), then the container (10) is turned over 180 ° and the assembly is suspended from a bracket.

L'écoulement de la préparation nutritive contenue dans le récipient (10) doit s'effectuer dans des conditions de lenteur suffisante pour que le malade ne subisse pas de phénomène d'intolé- rence digestive.The flow of the nutritive preparation contained in the container (10) must be carried out under conditions of sufficient slowness so that the patient does not undergo a phenomenon of digestive intolerance.

A cet effet, le conduit peut être doté d'un système de contrôle de débit, tel qu'un compte- gouttes et d'un système de régulation de vitesse d'écoulement, comme par exemple une pince de Mohr.For this purpose, the conduit can be provided with a flow control system, such as a dropper and with a flow speed regulation system, such as for example a Mohr forceps.

Grâce à la conception du dispositif de l'invention et à l'agencement de ses éléments, l'écoulement du contenu d'un récipient s'effectue dans les conditions recherchées.Thanks to the design of the device of the invention and the arrangement of its elements, the flow of the contents of a container takes place under the desired conditions.
