Definitions

  • the present invention relates to a pocket having a flexible external envelope comprising a collar followed by a flared part, the neck having a free end delimiting an opening, the pocket being likely to adopt a flattened configuration in which the aperture is closed, however the cervix is likely to adopt a substantially tubular configuration in which the opening is open, the pocket being, moreover, provided with a reinforcing element disposed at least near the free end of the neck.

Abstract

The pouch is made of e.g. a supple plastics material and has its neck equipped with a collar (222) of a semi-rigid material, such as stiff card or plastics. The collar lies flat when not in use and is opened by pressing its opposite ends towards one another. The lower edge of the collar is cut out to form two projecting tongues (226) which are designed to hold the top of the pouch open when in use. It also has a tab (244) formed by an additional cut-away portion (242) which retains the collar in its open position when folded upwards along a horizontal line (246).

Description

La présente invention concerne une poche présentant une enveloppe externe souple comprenant un col suivi par une partie évasée, le col ayant une extrémité libre délimitant une ouverture, la poche étant susceptible d'adopter une configuration aplatie dans laquelle l'ouverture est refermée, cependant que le col est susceptible d'adopter une configuration sensiblement tubulaire dans laquelle l'ouverture est ouverte, la poche étant, en outre, munie d'un élément de renfort disposé au moins au voisinage de l'extrémité libre du col.The present invention relates to a pocket having a flexible external envelope comprising a collar followed by a flared part, the neck having a free end delimiting an opening, the pocket being likely to adopt a flattened configuration in which the aperture is closed, however the cervix is likely to adopt a substantially tubular configuration in which the opening is open, the pocket being, moreover, provided with a reinforcing element disposed at least near the free end of the neck.

Des poches de ce type sont utilisées pour recevoir des déchets sous forme généralement liquide, notamment des déchets d'origine humaine tels que de l'urine ou des vomissures. Ces poches se présentent normalement dans leur forme aplatie et sont ouvertes pour recevoir les déchets. A cette occasion, la poche est maintenue au voisinage de l'extrémité libre du col pour contraindre ce dernier à adopter sa configuration sensiblement tubulaire. Une fois que les déchets ont été introduits, il suffit de relâcher l'extrémité libre du col pour que celui-ci reprenne naturellement sa configuration aplatie, refermant ainsi l'ouverture.Pockets of this type are used to receive waste in generally liquid form, including original waste human such as urine or vomit. These pockets show up normally in their flattened shape and are open to receive waste. On this occasion, the pocket is held in the vicinity of the free end of the neck to force the latter to adopt its substantially tubular configuration. Once the waste has been introduced, it is enough to release the free end of the neck so that it naturally resumes its flattened configuration, thus closing the opening.

De telles poches sont couramment réalisées au moyen de feuilles minces de papier ou de matière plastique, éventuellement transparentes, dotées de la souplesse voulue. Pour l'ouverture, l'élément de renfort est déformé par l'utilisateur, ce qui contraint la partie du col disposée autour de cet élément à adopter la configuration tubulaire souhaitée.Such bags are commonly made using sheets thin paper or plastic, possibly transparent, with the flexibility you want. For the opening, the reinforcing element is deformed by the user, which constrains the part of the neck arranged around of this element to adopt the desired tubular configuration.

Les dimensions transversales de l'ouverture sont choisies de manière appropriée à l'usage que l'on souhaite faire de la poche. Généralement, surtout lorsque la poche est destinée à recevoir des urines ou des vomissures, l'ouverture doit pouvoir être manipulée avec une seule main, de sorte que ses dimensions transversales sont nettement inférieures aux dimensions transversales courantes de la poche. Par exemple, lorsque la poche est utilisée comme urinal, sa largeur maximale et celle de l'ouverture peuvent respectivement varier entre 15 et 20 cm et entre 4 et 10 cm, selon que l'utilisateur est un adulte ou un enfant.The transverse dimensions of the opening are chosen from appropriately for the use you wish to make of the pocket. Generally, especially when the bag is intended to receive urine or vomit, the opening must be able to be handled with just one hand, so that its transverse dimensions are clearly smaller than the current transverse dimensions of the pocket. By example, when the bag is used as urinal, its maximum width and that of the opening can vary respectively between 15 and 20 cm and between 4 and 10 cm, depending on whether the user is an adult or a child.

La présence de l'élément de renfort permet d'ouvrir l'ouverture de l'extrémité supérieure du col en rapprochant les deux bords longitudinaux de cet élément qui déterminent sa largeur maximale dans la configuration aplatie. Toutefois, du fait de la souplesse du matériau qui constitue l'enveloppe externe de la poche, il existe un risque que seul le col soit convenablement ouvert, tandis que le reste de l'enveloppe externe reste plat, les feuilles qui constituent cette enveloppe ayant naturellement tendance à rester "collées" les unes aux autres. Par conséquent, lors de l'utilisation, il existe un risque de reflux vers l'extérieur pour le produit versé dans la poche.The presence of the reinforcing element makes it possible to open the opening of the upper end of the neck by bringing the two longitudinal edges together of this element which determine its maximum width in the configuration flattened. However, due to the flexibility of the material which constitutes the outer envelope of the pocket, there is a risk that only the collar is suitably open, while the rest of the outer casing remains flat, the leaves which constitute this envelope having naturally tendency to remain "glued" to each other. Therefore, when use, there is a risk of outward flow back to the product poured into the pocket.

L'invention a pour but de remédier à cet inconvénient en proposant une poche pour laquelle le passage à la configuration tubulaire du col assure l'écartement des parois de l'enveloppe externe non seulement dans la région de ce col, mais également au moins dans la région de la partie évasée proche du col.The object of the invention is to remedy this drawback by proposing a pocket for which the passage to the tubular configuration of the neck ensures the spacing of the walls of the external envelope not only in the region of this pass, but also at least in the region of the flared part near the neck.

Ce but est atteint grâce au fait que l'élément de renfort est constitué par un manchon relativement rigide et flexible disposé à l'intérieur de la poche, ce manchon s'étendant dans le col à partir d'une première extrémité située au voisinage de l'ouverture, jusqu'à une deuxième extrémité située du côté de la partie évasée, que le manchon présente, au voisinage de la base du col raccordée à la partie évasée, une découpe de part et d'autre de laquelle sont délimitées une première portion située du côté de la première extrémité du manchon et une deuxième portion située du côté de la deuxième extrémité dudit manchon, la deuxième portion étant munie d'au moins deux pattes sensiblement transversales qui se font face et qui ont des extrémités latérales libres, et que, dans la configuration aplatie de la poche, le manchon est lui-même aplati et présente deux éléments de paroi disposés l'un contre l'autre, tandis que, pour amener le col dans sa configuration sensiblement tubulaire et ouvrir l'ouverture, le manchon est susceptible d'être déformé élastiquement pour adopter une configuration dite "ouverte", dans laquelle la première portion est sensiblement tubulaire, cependant que les extrémités latérales des pattes sont écartées l'une de l'autre.This object is achieved thanks to the fact that the reinforcing element is consisting of a relatively rigid and flexible sleeve disposed at inside the pocket, this sleeve extending into the neck from a first end located near the opening, up to a second end located on the side of the flared part, that the sleeve presents, in the vicinity of the base of the neck connected to the flared part, a cut on either side of which are delimited a first portion located on the side of the first end of the sleeve and a second portion located on the side of the second end of said sleeve, the second portion being provided with at least two legs substantially facing each other and having free lateral ends, and that, in the flattened configuration of the pocket, the sleeve is itself flattened and has two wall elements arranged one against the other, while, to bring the neck into its configuration substantially tubular and open the opening, the sleeve may be deformed elastically to adopt a so-called "open" configuration, in which the first portion is substantially tubular, while the lateral ends of the legs are spaced from one another.

On comprend que, grâce à cette conformation, la déformation du manchon permet non seulement d'amener le col à son diamètre d'ouverture grâce à la première portion du manchon, mais également d'écarter les parois de la poche au moins dans la partie évasée de son enveloppe externe du fait de l'écartement des pattes qui équipent la deuxième portion du manchon. We understand that, thanks to this conformation, the deformation of the sleeve not only brings the neck to its diameter opening thanks to the first portion of the sleeve, but also to spread the walls of the pocket at least in the flared part of its outer shell due to the spacing of the legs which equip the second portion of the sleeve.

La précision selon laquelle le manchon est "relativement rigide et flexible" signifie qu'il est réalisé dans un matériau doté d'une rigidité supérieure à celle de la paroi externe de la poche. Par exemple, le manchon peut être réalisé dans un carton léger ou dans un plastique d'épaisseur supérieure à celle du plastique qui constitue la paroi externe.The clarification that the sleeve is "relatively rigid and flexible "means that it is made of a material with rigidity greater than that of the external wall of the pocket. For example, the sleeve can be made of light cardboard or plastic of thickness greater than that of the plastic which constitutes the external wall.

Selon un mode de réalisation particulièrement avantageux, le manchon comporte un organe de maintien en configuration d'ouverture, susceptible d'être actionné pour maintenir ledit manchon dans sa conformation ouverte.According to a particularly advantageous embodiment, the sleeve includes a holding member in the opening configuration, capable of being actuated to maintain said sleeve in its open conformation.

Cet organe de maintien, par exemple formé par une languette ménagée dans une zone de pliage du manchon, est particulièrement intéressant lorsque la poche est destinée à servir d'urinal à usage féminin, puisqu'il permet d'éviter toute fermeture intempestive de la poche même si, du fait d'une mauvaise manipulation, la sollicitation de la main plaçant le manchon dans sa configuration ouverte est malencontreusement relâchée.This holding member, for example formed by a tongue formed in a bend zone of the sleeve, is particularly interesting when the bag is intended to serve as a urinal for female use, since it avoids any untimely closing of the pocket itself if, due to improper handling, the stress of the hand placing the sleeve in its open configuration is unfortunately released.

L'invention sera bien comprise et ses avantages apparaítront mieux à la lecture de la description détaillée qui suit, d'un mode de réalisation et de ses variantes représentés à titre d'exemples non limitatifs. La description se réfère aux dessins annexés sur lesquels :

La figure 1 montre une poche de sécurité 10, par exemple destinée à être utilisée comme urinal. Cette poche comporte une enveloppe externe 12 qui est souple. Cette enveloppe est par exemple réalisée à partir de deux feuilles minces de matière plastique découpées de manière convenable et soudées l'une sur l'autre sur presque l'intégralité du contour, par une ligne de soudure 14.FIG. 1 shows a safety pocket 10, for example intended to be used as urinal. This pocket has an envelope external 12 which is flexible. This envelope is for example produced at from two thin sheets of plastic cut so suitable and welded to each other over almost the entire outline, by a weld line 14.

L'enveloppe 12 comprend un col 16 qui, dans le sens allant vers le fond de la poche, est suivi par une partie évasée 18, elle-même suivie par une partie utile 20 de la poche qui présente une largeur sensiblement constante.The envelope 12 comprises a neck 16 which, in the direction going towards the bottom of the pocket, is followed by a flared portion 18, itself followed by a useful part 20 of the pocket which has a width which is substantially constant.

Plus précisément, dans l'exemple représenté, un bord 12a de l'enveloppe 12 est sensiblement rectiligne à partir de l'extrémité libre du col 16, tandis que le bord opposé 12'a présente tout d'abord une première portion 12b qui est située dans la région du col 16 et qui est sensiblement parallèle au bord 12a dans cette région, ou qui a tout au plus tendance à s'écarter légèrement de ce bord 12a. Le bord 12'a présente ensuite une deuxième portion 12c qui va en s'écartant du bord 12a. C'est cette portion 12c qui définit la portion évasée 18 de l'enveloppe externe. Enfin, la partie utile 20 de la poche est délimitée entre le bord 12a et la portion 12d du bord 12'a qui lui fait face. Cette portion 12d peut être sensiblement parallèle au bord 12a ou, comme dans l'exemple représenté, avoir légèrement tendance à se rapprocher de ce dernier. D'autres configurations sont encore possibles, l'essentiel étant d'obtenir un volume interne correspondant à l'utilisation que l'on souhaite faire de la poche. Enfin, le bord 12a et la portion 12d du bord 12'a sont raccordés par le fond 12e de la poche, qui est situé à l'opposé de l'extrémité libre 16a du col 16.More specifically, in the example shown, an edge 12a of the envelope 12 is substantially straight from the free end of the neck 16, while the opposite edge 12 ′ a first presents a first portion 12b which is located in the region of the neck 16 and which is substantially parallel to edge 12a in this region, or which at most tends to slightly deviate from this edge 12a. The edge 12'a then has a second portion 12c which goes away from the edge 12a. It's that portion 12c which defines the flared portion 18 of the external envelope. Finally, the part useful 20 of the pocket is delimited between the edge 12a and the portion 12d of the edge 12'a facing it. This portion 12d can be substantially parallel to edge 12a or, as in the example shown, have slightly tending to approach the latter. Others configurations are still possible, the main thing being to obtain a volume internal corresponding to the use that one wishes to make of the pocket. Finally, the edge 12a and the portion 12d of the edge 12'a are connected by the bottom 12e of the pocket, which is located opposite the free end 16a of the col 16.

On a indiqué précédemment que la soudure 14 était presque continue. En fait, comme on le voit sur la figure 1, cette soudure forme une ligne continue entre deux extrémités 14a et 14b entre lesquelles elle est interrompue. Ces extrémités sont situées de chaque côté du col 16. Ainsi, l'extrémité 16a du col présente une ouverture 17 qui s'étend sur sensiblement toute sa largeur. Dans toute la suite, on considérera que la longueur des différents éléments de la poche est définie dans la direction, donnée par l'axe D, qui va de l'extrémité libre 16a du col au fond 12e de la poche, tandis que la largeur des différents éléments est définie transversalement à cette longueur.It was previously indicated that the weld 14 was almost keep on going. In fact, as seen in Figure 1, this weld forms a continuous line between two ends 14a and 14b between which it is interrupted. These ends are located on each side of the neck 16. Thus, the end 16a of the neck has an opening 17 which extends over substantially its entire width. In the following, we will consider that the length of the various elements of the pocket is defined in the direction, given by axis D, which goes from the free end 16a of the neck to the bottom 12e of the pocket, while the width of the different elements is defined transversely to this length.

La poche comporte un élément de renfort 22 constitué par un manchon relativement rigide et flexible qui est disposé à l'intérieur de la poche, dans la région du col 16. Plus précisément, ce manchon s'étend dans le col à partir d'une première extrémité 22a disposée au voisinage de l'ouverture 17, jusqu'à une deuxième extrémité 22b qui est située à l'intérieur de la poche, dans la région de la partie évasée 18. Au voisinage de la base 16b du col 16 (c'est-à-dire au voisinage de la zone de raccordement entre le col et la partie évasée), ce manchon présente une découpe 24 de part et d'autre de laquelle sont délimitées une première portion 23a et une deuxième portion 23b. La portion 23a s'étend entre la découpe 24 et l'extrémité 22a du manchon, tandis que la portion 23b s'étend entre la découpe et l'extrémité 22b.The pocket includes a reinforcing element 22 constituted by a relatively rigid and flexible sleeve which is disposed inside the pocket, in the region of the neck 16. More precisely, this sleeve extends in the neck from a first end 22a disposed in the vicinity from the opening 17, to a second end 22b which is located at inside the pocket, in the region of the flared part 18. In the vicinity from the base 16b of the neck 16 (i.e. in the vicinity of the area of connection between the neck and the flared part), this sleeve has a cutout 24 on either side of which are delimited a first portion 23a and a second portion 23b. The portion 23a extends between the cutout 24 and the end 22a of the sleeve, while the portion 23b extends between the cutout and the end 22b.

La deuxième portion 23b est munie de deux pattes 26 sensiblement transversales à l'axe D. Dans la position aplatie de la poche, les deux pattes 26 sont disposées l'une contre l'autre, ce qui explique que l'on n'en voie qu'une seule sur la figure 1. En revanche, sur la figure 2, les deux pattes 26 sont visibles. Les extrémités latérales 26a des pattes sont libres, c'est-à-dire que ces extrémités ne se rejoignent pas et ne sont pas fixées entre elles. Ainsi, la découpe 24 comporte deux encoches 24a et 24b qui sont sensiblement transversales et, éventuellement, une ligne de découpe séparant les extrémités 26a des deux pattes.The second portion 23b is provided with two legs 26 substantially transverse to the axis D. In the flattened position of the pocket, the two legs 26 are arranged one against the other, which explains why we only see one in figure 1. On the other hand, in figure 2, the two tabs 26 are visible. The lateral ends 26a of the legs are free, that is to say that these ends do not meet and are not fixed together. Thus, the cutout 24 has two notches 24a and 24b which are substantially transverse and, optionally, a line of cut separating the ends 26a of the two legs.

Le manchon est fixé à l'intérieur de la poche et, comme on le voit sur la figure 1, il est fixé dans la région du col à l'aide de deux soudures transversales 15a et 15b.The sleeve is fixed inside the pocket and, as we can see in Figure 1, it is fixed in the neck region using two welds 15a and 15b.

La première portion 23a du manchon s'étend sur sensiblement toute la largeur du col 16, c'est-à-dire que la distance qui, dans la configuration aplatie, sépare les bords longitudinaux 22c et 22d du manchon dans sa première portion est sensiblement égale à la largeur du col donnée par la distance entre les extrémités 14a et 14b de la soudure 14. La deuxième portion s'étend globalement dans le prolongement de la première, vers le fond 12e de la poche. Toutefois, comme on l'a indiqué en traits mixtes interrompus sur la figure 1, la dimension transversale d maximale de la deuxième portion dans la région des pattes peut être supérieure à la largeur courante de la première portion. Cette disposition vise à augmenter encore l'effet des pattes qui est d'écarter les deux parois de la poche dans la région située en dessous du col.The first portion 23a of the sleeve extends over substantially the entire width of the neck 16, that is to say the distance which, in the flattened configuration, separates the longitudinal edges 22c and 22d from the sleeve in its first portion is substantially equal to the width of the neck given by the distance between the ends 14a and 14b of the weld 14. The second portion generally extends in line with the first, toward the 12th bottom of the pocket. However, as noted in broken lines in FIG. 1, the transverse dimension d maximum of the second portion in the leg region can be greater than the current width of the first portion. This provision aims to further increase the effect of the legs which is to separate the two walls from the pocket in the region below the neck.

On voit en effet sur la figure 2 la partie supérieure de la poche dans la configuration ouverte de cette dernière. Pour parvenir à cette configuration, le manchon est déformé élastiquement, de telle sorte que sa première portion 23a adopte une configuration sensiblement tubulaire. En revanche, grâce à la découpe 24 et au fait que les extrémités latérales des pattes sont libres, ces dernières restent sensiblement rectilignes. Elles sont raccordées à la partie courante du manchon par leurs extrémités internes 26b opposées aux extrémités 26a. Lorsque l'on déforme le manchon comme sur la figure 2, les extrémités internes 26b prennent un écartement donné, fonction du diamètre de la première portion du manchon. Les pattes 26 conservent alors, sur pratiquement toute leur longueur, un écartement e sensiblement égal à l'écartement entre leurs extrémités internes respectives.We can see in Figure 2 the upper part of the pocket in the open configuration of the latter. To achieve this configuration, the sleeve is elastically deformed, so that its first portion 23a adopts a substantially tubular configuration. However, thanks to the cutout 24 and the fact that the lateral ends legs are free, the latter remain substantially straight. They are connected to the current part of the sleeve by their internal ends 26b opposite ends 26a. When we deforms the sleeve as in FIG. 2, the internal ends 26b take a given distance, depending on the diameter of the first portion of the sleeve. The legs 26 then retain, on practically their entire length, a spacing e substantially equal to the spacing between their respective internal ends.

Ainsi, lorsque l'on déforme le manchon, le col 16 de la poche qui est disposé autour de la première portion 23a du manchon adopte une forme tubulaire dont le diamètre est déterminé par l'écartement maximal des parois en regard du manchon. Les pattes 26 s'étendent dans la partie évasée 18 de la poche et tendent à écarter cette dernière qui, dans un plan perpendiculaire à celui de la figure 1 passant par l'axe D, adopte sensiblement le diamètre de la première portion 23a du manchon et qui, dans la région des extrémités des pattes 26 (région qui est éloignée de l'axe D) adopte l'écartement e. Ainsi, les parois de la poche se décollent l'une de l'autre dans la région de la partie évasée.Thus, when the sleeve is deformed, the neck 16 of the pocket which is arranged around the first portion 23a of the sleeve adopts a tubular shape whose diameter is determined by the maximum spacing walls opposite the sleeve. The legs 26 extend in the part flared 18 from the pocket and tend to spread the latter which, in a plane perpendicular to that of Figure 1 passing through the axis D, adopts substantially the diameter of the first portion 23a of the sleeve and which, in the region of the ends of the legs 26 (region which is distant from axis D) adopts spacing e. Thus, the walls of the pocket come off each other in the region of the flared part.

Dans l'exemple représenté, la partie évasée 18 est obtenue en faisant en sorte que la portion 12c du bord 12'a s'écarte du bord 12a. Dans ces conditions, il est avantageux que les pattes soient dirigées vers cette portion 12c.In the example shown, the flared part 18 is obtained by causing the portion 12c of the edge 12'a to move away from the edge 12a. Under these conditions, it is advantageous for the legs to be directed towards this portion 12c.

Si la portion évasée avait une autre conformation, par exemple une forme tronconique symétrique par rapport à l'axe D, on pourrait choisir de réaliser un manchon analogue à celui de la figure 1 en dirigeant ses pattes vers l'un ou vers l'autre des deux bords de la portion tronconique. On pourrait également choisir d'utiliser un manchon comportant quatre pattes analogues aux pattes 26, respectivement disposées de part et d'autre de l'axe D de manière à bien écarter les parois de la poche dans la partie évasée, dans deux directions opposées partant transversalement à l'axe D.If the flared portion had another conformation, for example a frustoconical shape symmetrical about the D axis, we could choose to make a sleeve similar to that of Figure 1 by directing its legs towards one or the other of the two edges of the frustoconical portion. One could also choose to use a sleeve comprising four legs similar to legs 26, respectively arranged on the side and on the other side of the axis D so as to spread the walls of the pocket well in the flared part, in two opposite directions going transversely to axis D.

Globalement, la première portion 23a du manchon présente une symétrie par rapport à l'axe D. Notamment, dans la configuration ouverte, cet axe correspond à l'axe géométrique du tube que forme la première portion 23a du manchon. Dans ces conditions, le diamètre de ce tube est donné par l'écartement des deux parois opposées du manchon, mesuré selon un plan passant par l'axe D et perpendiculaire au plan de la poche dans sa configuration aplatie. Il est avantageux de faire en sorte que l'écartement e des extrémités des pattes soit sensiblement égal à ce diamètre. Pour ce faire, comme on le voit sur la figure 1, la découpe qui ménage les deux pattes s'étend sensiblement jusqu'à l'axe D à partir d'un bord longitudinal 22c que présente le manchon dans sa configuration aplatie. Dans l'exemple représenté, ce bord 22c est celui des bords longitudinaux du manchon qui est voisin de la portion 12c du bord de la poche.Overall, the first portion 23a of the sleeve has a symmetry with respect to the D axis. In particular, in the open configuration, this axis corresponds to the geometric axis of the tube that the first forms portion 23a of the sleeve. Under these conditions, the diameter of this tube is given by the spacing of the two opposite walls of the sleeve, measured along a plane passing through the axis D and perpendicular to the plane of the pocket in its flattened configuration. It pays to have the spacing e of the ends of the legs is substantially equal to this diameter. To do this, as seen in Figure 1, the cutout cleaning the two legs extends substantially to the axis D from a longitudinal edge 22c presented by the sleeve in its configuration flattened. In the example shown, this edge 22c is that of the edges longitudinal of the sleeve which is close to the portion 12c of the edge of the poached.

De préférence, il est même souhaitable que cette découpe s'étende, dans la direction allant du bord 22c au bord opposé 22d, au-delà de l'axe D. Ainsi, les extrémités 26b des pattes sont reliées à la partie courante du manchon dans une région sur laquelle les parois du manchon divergent en configuration ouverte, c'est-à-dire qu'elles vont en s'écartant l'une de l'autre, lorsque l'on ouvre le manchon. Les pattes étant relativement rigides, elles ont ainsi tendance, lorsque le manchon est ouvert, à s'écarter en suivant la direction divergente donnée par les parois du manchon dans la région de leurs extrémités internes 26b. Ainsi, même si les parois de la poche ont quelque peu tendance à résister à l'écartement des pattes 26, on peut s'assurer que l'espacement e entre les extrémités 26a de ces pattes est suffisant. Pour que les pattes aient la rigidité souhaitée, il est toutefois préférable que la découpe 24 ne s'étende pas trop au-delà de l'axe D mais dépasse seulement de quelques millimètres.Preferably, it is even desirable that this cutting extends, in the direction from edge 22c to opposite edge 22d, beyond of the axis D. Thus, the ends 26b of the legs are connected to the part current of the sleeve in a region on which the walls of the sleeve diverge in open configuration, that is to say that they move apart from each other, when the sleeve is opened. The legs being relatively rigid, they thus tend, when the sleeve is open, to move away in the divergent direction given by the walls of the sleeve in the region of their internal ends 26b. So even if the pocket walls have a tendency to resist the spacing of the legs 26, it can be ensured that the spacing e between the ends 26a of these legs is sufficient. So that the legs have the desired stiffness, it is however preferable that the cut 24 does not does not extend too far beyond the D axis but only exceeds by a few millimeters.

Selon l'exemple représenté sur les figures 1 à 3, le manchon comporte deux plaquettes analogues 25a et 25b qui constituent respectivement les premier et deuxième éléments de paroi que présente le manchon dans sa configuration aplatie. Ces plaquettes sont naturellement planes et sont réalisées en carton léger ou en plastique relativement rigide et flexible. Les plaquettes sont respectivement fixées (par exemple par collage ou par soudure) sur les faces internes de la poche qui se trouvent en regard l'une de l'autre lorsqu'elle occupe sa configuration aplatie. Les plaquettes sont fixées de telle sorte que leurs extrémités longitudinales soient adjacentes deux à deux et respectivement voisines des deux bords longitudinaux que présente le col 16 dans la configuration aplatie de la poche. Ainsi, les deux bords longitudinaux des plaquettes définissent respectivement les bords 22c et 22d du manchon précédemment évoqué et ne sont pas désignés par d'autres références.According to the example shown in Figures 1 to 3, the sleeve comprises two similar plates 25a and 25b which constitute respectively the first and second wall elements that presents the sleeve in its flattened configuration. These plates are naturally flat and made of light cardboard or plastic relatively rigid and flexible. The plates are respectively fixed (for example by gluing or welding) on the internal faces of the pocket which are facing each other when it occupies its flattened configuration. The plates are fixed so that their longitudinal ends are adjacent two by two and respectively adjacent to the two longitudinal edges presented by the neck 16 in the flattened pocket configuration. Thus, the two longitudinal edges of the plates respectively define the edges 22c and 22d of the sleeve previously mentioned and are not designated by other references.

Pour former la découpe 24, chaque plaquette présente une encoche sensiblement transversale, respectivement 24a et 24b. Pour chaque plaquette, on distingue une première et une deuxième portion qui s'étendent respectivement de part et d'autre de cette encoche et qui correspondent respectivement aux première et deuxième portions du manchon. Il faut noter qu'une autre découpe rendant les extrémités latérales des pattes libres n'est pas nécessaire dans la mesure où ces extrémités coïncident normalement avec les bords longitudinaux des plaquettes qui sont initialement séparés l'un de l'autre et sont simplement maintenus en position grâce au fait que la largeur des premières portions des plaquettes est sensiblement égale à celle du col.To form the cutout 24, each plate has a substantially transverse notch, respectively 24a and 24b. For each plate, there is a first and a second portion which extend respectively on either side of this notch and which correspond respectively to the first and second portions of the muff. It should be noted that another cut making the ends side of the free legs is not necessary since these ends normally coincide with the longitudinal edges of the pads which are initially separated from each other and are simply kept in position thanks to the fact that the width of the first portions platelets is substantially equal to that of the cervix.

Les deux pattes sont constituées par les portions des plaquettes situées entre leur découpe respective et celle de leurs extrémités qui est dirigée vers l'intérieur de la poche. Chaque plaquette présente deux bords longitudinaux qui sont respectivement situés au voisinage des deux bords longitudinaux que présente le col lorsque la poche est dans sa configuration aplatie.The two legs are formed by the portions of the pads located between their respective cutout and that of their ends which is directed towards the inside of the pocket. Each plate has two edges longitudinal which are respectively located in the vicinity of the two edges the neck presents when the pocket is in its flattened configuration.

Comme on le voit sur les dessins, les extrémités latérales 26a des pattes sont arrondies pour éviter de blesser les parois de la poche lors de leur écartement.As can be seen in the drawings, the lateral ends 26a of the legs are rounded to avoid injuring the walls of the pocket when their spacing.

On remarque également que les bords supérieurs 26c des pattes, c'est-à-dire les bords qui sont tournés vers l'ouverture de la poche, ne sont pas tout à fait transversaux mais sont légèrement inclinés de manière à s'étendre sensiblement parallèlement à la portion évasée de l'enveloppe externe de la poche, plus précisément à son bord 12c. De ce fait, les pattes ont une forme tout à fait adaptée à celle de la portion évasée de la poche dans laquelle elles se trouvent et ouvrent cette dernière sans difficulté.We also note that the upper edges 26c of the legs, i.e. the edges which face the opening of the pocket, do not are not completely transverse but are slightly inclined so to extend substantially parallel to the flared portion of the envelope outer pocket, more precisely on its edge 12c. Therefore, the legs have a shape perfectly suited to that of the flared portion of the pocket in which they are located and open the latter without difficulty.

La découpe 24 est située au voisinage de la base du col 16 et, de préférence, légèrement en dessous de cette base dans le sens allant vers le fond 12e de la poche. The cutout 24 is located in the vicinity of the base of the neck 16 and, from preferably slightly below this base in the direction of the 12th bottom of the pocket.

On voit sur les figures que le manchon 22 comporte un prolongement 27 qui s'étend vers l'extérieur au-delà de l'ouverture 17. Ce prolongement est muni de moyens pour faciliter le passage de la configuration aplatie du manchon à sa configuration tubulaire. ll s'agit de moyens de préhension qui permettent de bien saisir les parois en regard du manchon pour les écarter légèrement tout en rapprochant les bords longitudinaux 22c et 22d. Dans l'exemple des figures 1 et 2, ces moyens de préhension sont simplement constitués par deux languettes 27a et 27b qui équipent respectivement les deux parois du manchon parallèles aux deux parois en regard de la poche.We see in the figures that the sleeve 22 has a extension 27 which extends outwards beyond the opening 17. This extension is provided with means to facilitate the passage of the flattened configuration of the sleeve to its tubular configuration. lt's about gripping means which make it possible to grasp the facing walls well the sleeve to spread them slightly while bringing the edges together 22c and 22d. In the example of FIGS. 1 and 2, these means grip are simply formed by two tabs 27a and 27b which respectively equip the two walls of the sleeve parallel to the two walls facing the pocket.

La figure 3 montre une variante de réalisation, sur laquelle, pour simplifier, le contour de l'enveloppe est simplement indiqué par des traits mixtes interrompus. On voit que le prolongement 127 du manchon 122 présente deux languettes, respectivement 127a et 127b, qui, contrairement à l'exemple de la figure 2, n'ont pas la même forme. En effet, ces deux languettes présentent deux surfaces de préhension décalées. Pour réaliser ces surfaces, il suffit de découper le prolongement 127 de chacun des deux éléments de paroi du manchon ou de chacune de ses deux parois en regard, de manière asymétrique par rapport à l'axe D. Ainsi, une portion découpée du prolongement de la première plaquette se trouve en regard d'une portion restée pleine du prolongement de la deuxième plaquette.FIG. 3 shows an alternative embodiment, in which, for simplify, the outline of the envelope is simply indicated by lines mixed interrupted. We see that the extension 127 of the sleeve 122 has two tabs, respectively 127a and 127b, which, unlike the example in Figure 2, do not have the same shape. In effect, these two tabs have two gripping surfaces staggered. To make these surfaces, just cut the extension 127 of each of the two wall elements of the sleeve or of each of its two facing walls, asymmetrically with respect to the axis D. Thus, a cut portion of the extension of the first wafer is located opposite a portion that remains full of the extension of the second brochure.

Sur les figures 4 à 6, on utilise, pour désigner les éléments communs aux figures 1 et 2, les mêmes références que sur ces figures, augmentées de 200. Le manchon 222 comporte un organe de maintien en configuration d'ouverture.In Figures 4 to 6, we use to designate the elements common to FIGS. 1 and 2, the same references as in these figures, increased by 200. The sleeve 222 includes a holding member in opening configuration.

Plus précisément, le manchon présente une zone de pliage 240, mieux visible sur la figure 5, de part et d'autre de laquelle s'étendent ses deux éléments de paroi 225a et 225b. Une découpe 242 est formée dans le manchon et s'étend de part et d'autre de la zone de pliage, avantageusement symétriquement par rapport à cette dernière. Cette découpe 242 laisse subsister une languette 244 qui, comme on le voit sur la figure 6, peut être pliée sur elle-même. Dans cette situation, la ligne de pliure 246 de la languette s'étend sensiblement transversalement à la zone de pliage 240 et vient en quelque sorte casser la continuité de cette zone de pliage, ce qui empêche les deux éléments de paroi 225a et 225b de se rabattre l'un contre l'autre. La languette 244, une fois qu'elle est pliée comme le montre la figure 6, maintient donc le manchon dans sa configuration ouverte.More specifically, the sleeve has a folding zone 240, better visible in Figure 5, on either side of which extend its two wall elements 225a and 225b. A cutout 242 is formed in the sleeve and extends on either side of the folding zone, advantageously symmetrically with respect to the latter. This cutout 242 leaves a tab 244 which, as seen on Figure 6, can be folded on itself. In this situation, the line of fold 246 of the tongue extends substantially transversely to the folding zone 240 and somehow breaks the continuity of this folding area, which prevents the two wall elements 225a and 225b to fall back against each other. Tab 244, once it is folded as shown in Figure 6, therefore keeps the sleeve in its open configuration.

La languette 244 reste dans sa position repliée grâce à la relative rigidité du matériau qui constitue le manchon et au point dur que forme la cassure 240a de la zone de pliage 240.The tongue 244 remains in its folded position thanks to the relative rigidity of the material which constitutes the sleeve and the hard point formed by the break 240a of the bending zone 240.

La découpe 242 peut par exemple présenter sensiblement la forme d'un "V" comme sur les figures, celle d'un "V" renversé ou une autre forme du même type.The cutout 242 can for example have substantially the shape of a "V" as in the figures, that of an inverted "V" or another form of the same type.

Sur la figure 6, la languette 244 est située dans le prolongement 227 du manchon qui s'étend vers l'extérieur au-delà de l'ouverture 217, ce qui permet de plier cette languette vers l'extérieur du manchon. Il est toutefois possible de choisir de la plier vers l'intérieur du manchon, et elle peut être située dans la partie du manchon s'étendant dans la poche.In Figure 6, the tongue 244 is located in the extension 227 of the sleeve which extends outwards beyond the opening 217, this which allows this tab to be folded outwards from the sleeve. It is however possible to choose to fold it towards the inside of the sleeve, and it can be located in the part of the sleeve extending into the pocket.

Dans l'exemple représenté, la languette 244 est disposée dans la région du manchon opposée aux extrémités libres des pattes 226.In the example shown, the tongue 244 is arranged in the sleeve region opposite the free ends of tabs 226.

Dans l'exemple des figures 4 à 6, le manchon est réalisé en une seule pièce et est formée dans une plaquette qui est repliée sur elle-même selon une zone de pliage 240. Comme on le voit mieux sur la figure 5, on peut d'ailleurs choisir de n'écraser la zone de pliage 240 pour former un véritable pli que sur une hauteur h à partir de la deuxième extrémité 222b du manchon, ce qui facilite le passage de la configuration aplatie à la configuration ouverte du manchon.In the example of FIGS. 4 to 6, the sleeve is made in one single piece and is formed in a wafer which is folded back on itself according to a folding zone 240. As can be seen better in the figure 5, it is also possible to choose not to crush the folding zone 240 to form a real fold only over a height h from the second end 222b of the sleeve, which facilitates the transition from the flattened configuration to the open configuration of the sleeve.

Lorsque la poche est destinée à être utilisée comme urinal, la partie supérieure 27, 127 ou 227 du manchon peut être conformée de manière à s'adapter au sexe (masculin ou féminin) de l'utilisateur, une pièce additionnelle d'adaptation pouvant être prévue.When the bag is intended to be used as urinal, the part upper 27, 127 or 227 of the sleeve can be shaped so as to adapt to the user's gender (male or female), one piece additional adaptation that may be expected.

Pour l'usage masculin, la forme de la première extrémité 22a ou 222a importe peu, il suffit que la partie tubulaire du manchon dans la configuration ouverte de ce dernier présente un diamètre suffisant.For male use, the shape of the first end 22a or 222 does not matter, it suffices that the tubular part of the sleeve in the open configuration of the latter has a sufficient diameter.

Pour l'usage féminin, comme le montrent les figures 4 à 6, il est préférable que la première extrémité 222a du manchon présente un bord concave, symétrique par rapport au plan d'aplatissement du manchon. Ainsi, pour l'utilisation de la poche, le bord du manchon peut être écarté de manière à dégager le méat urétral en s'adaptant au mieux à la conformation du sexe de l'utilisatrice, sans risque de fuite lors de la miction.For female use, as shown in Figures 4 to 6, it is preferable that the first end 222a of the sleeve has an edge concave, symmetrical with respect to the plane of flattening of the sleeve. Thus, for the use of the pocket, the edge of the sleeve can be spread so as to free the urethral meatus by adapting as best as possible to the conformation of the user's gender, without risk of leakage during urination.

Comme on le voit sur la figure 1, la poche peut comporter un clapet de sécurité, par exemple constitué par plusieurs feuilles internes disposées contre chacune des parois de la poche. Dans l'exemple représenté, ce clapet comporte ainsi, pour chaque paroi de la poche, une première paire de feuilles 30 qui s'étend à partir de l'ouverture jusqu'à une région médiane de la poche. Le clapet comporte également une deuxième paire de feuilles 32 qui s'étend à l'intérieur de la paire 30, également à partir de l'ouverture, sur une longueur légèrement moindre que celle de la paire 30. La paire de feuilles 30 et la paire de feuilles 32 sont soudées ensemble par des points de soudure 31 régulièrement espacés. Le clapet comporte enfin une troisième paire de feuilles 34 qui s'étend à l'intérieur de la paire 32 sur une longueur encore moindre que celle de la paire 32 et qui est soudée aux paires 30 et 32 par des points de soudure 33 qui sont régulièrement espacés et décalés par rapport au point de soudure 31.As seen in Figure 1, the pocket may have a valve security, for example consisting of several internal sheets arranged against each of the walls of the pocket. In the example shown, this valve thus comprises, for each wall of the pocket, a first pair of sheets 30 which extends from the opening to a middle region of the pocket. The valve also has a second pair of sheets 32 which extends inside the pair 30, also at from the opening, over a slightly shorter length than that of the pair 30. The pair of sheets 30 and the pair of sheets 32 are welded together by regularly spaced solder points 31. The valve finally has a third pair of sheets 34 which extends inside of pair 32 over an even shorter length than that of pair 32 and which is soldered to pairs 30 and 32 by solder points 33 which are regularly spaced and offset from the welding point 31.

Dans ce cas, la "paroi interne" de la poche est définie, dans la région du col, par les faces internes en regard des deux feuilles de la paire 34 la plus interne. Le manchon est donc au contact de ces faces internes. Ainsi, les premières (respectivement les deuxièmes) feuilles de chaque paire 30, 32, 34 sont prises en "sandwich" entre une première (respectivement une deuxième) paroi du manchon (plaquette 25a ou 25b) et une première (respectivement une deuxième) paroi de l'enveloppe externe 12. Les soudures 15a et 15b soudent donc ensemble, de chaque côté de la poche, une paroi du manchon, une feuille de chaque paire 30, 32, 34 et une paroi de l'enveloppe 12.In this case, the "internal wall" of the pocket is defined, in the neck region, by the internal faces opposite the two leaves of the innermost pair 34. The sleeve is therefore in contact with these faces internal. Thus, the first (respectively the second) sheets of each pair 30, 32, 34 are sandwiched between a first (respectively a second) wall of the sleeve (plate 25a or 25b) and a first (respectively a second) wall of the envelope external 12. The welds 15a and 15b therefore weld together, of each side of the pocket, a wall of the sleeve, a sheet of each pair 30, 32, 34 and a wall of the envelope 12.

Bien entendu, la poche munie du manchon selon l'invention peut comporter un clapet de sécurité diffèrent ou, selon les applications souhaitées, ne pas comporter de clapet.Of course, the pocket provided with the sleeve according to the invention can have a different safety valve or, depending on the applications do not have a valve.
