    The container flange can advantageously be manufactured by injection with manufacturing tolerances ranging from 1 to 2 mm over a diameter of 100 or 200 mm. The container flange is made of material having a given elasticity. The outer ears of outer ears (32) each have an elongated hole (41) defining an outer portion (40) of small width and which has an outwardly curved shape (40A), which increases the overall outer diameter of the container flange at the outer ear of about 1.2%. As a result, this outer portion (40) has a certain flexibility enabling them to flex inwardly of the container flange under the pressure of an inner wall of another entity, for example a containment enclosure. Application to containment enclosures and double door open / close systems.

    [0001] 1 PLASTIC CONTAINER BRACKET AND DOOR WITH COMPENSATION OF INJECTION TOLERANCES FOR CONNECTION DESCRIPTION PRIOR ART AND PROBLEM POSE In the double door seals, on the cell (also called glove box or isolator) is mounted a set consisting of a cell flange fixed to the wall of the cell in a sealed manner. This cell flange is closed by a cell door sealing by means of a generally elastomeric seal, preferably of the lip type. Such assemblies are generally made of stainless steel for cell flanges and generally of plastic for cell doors, less heavy, which facilitates the manipulation of operators. The object transfer is via containers consisting of a container flange having a seal and a container door sealingly closing the assembly, at the rear of the container flange is reported a container body with its bottom closing a closed and sealed volume. These assemblies are frequently made of machined plastic, which makes it possible to respect the tolerances and to guarantee the mechanical and sealing characteristics. Achievements were made in injected parts with a negative result on the degradation of the mechanical characteristics and sealing. This is due to injection tolerances much higher than those machined, which may call into question the use of these so-called double-door systems with rapid opening, in the case where the needs require a large number of containers because their cost becomes unbearable. The connection of the container to the cell flange is generally performed by bayonet system, the male ears of the container engaging in the female ears of the cell flange, followed by a rotation of the container of about 60 ° for four equidistant ears. This has the effect of locking the container flange to the cell flange, unlocking the container door from its container flange and locking it to the cell door. The number of ears and generally four, systems exist with three ears and others with six ears.
    [0002] FIG. 1 shows a conventional manufacturing assembly of a flange and cell door 4, the cell door 5 in the closed position seals with the cell flange 10 by its gasket 6, it is provided with a hinge 8 allowing its opening by a rotation about its axis 9. Note the ears 7 of the cell door 4 waiting to receive the inner lugs 24 of the container door 23 see Figure 2. The cell flange 10 is mounted sealingly on the wall 2 of the cell, by its seal 11 pressed under the action of the nut 13 and its pressure screws (not shown) pressing the support washer 12 on the wall 2. Note the outer ears 14 waiting to receive the ears 19 of the container flange 17 see Figure 2 at the connection of 16 out of 4 and the inlet slopes 15 for the outer ears 19 of the container flanges: 17 and 31 corresponding to the ear container flange self-compensating games 32 see Figures 4, and 5. Figure 2 shows a conventional manufacturing assembly of a container 16 comprising: a) - a container flange 17 having its seal 18 and its body with its bottom 21 the latter can be attached by welding or flange with a gasket and screw, also the container flange can end with a ferrule with bead allowing the tight fitting of a flexible bag used for the transfer of the components of the packaging machines. The container flange has outer lugs 19 enabling them to be locked on the lugs 14 of the cell flange 10 and the inner lugs 24 allowing them to be locked on the lugs 7 of the cell door 5. FIG. 3 represents the container assembly connected to the flange and cell door assembly. Arrow F1 indicates the approach phase of the entire container 16 over the entire flange and cell door 4.
    [0003] The arrow F2 indicates the locking phase by rotating (about 60 °) for four-ear assemblies) of the entire container 16 over the entire flange and cell door 4. In the same rotational movement takes place the locking of the container on the cell flange between the ears 19 on the ears 14, the unlocking of the container door of its flange between the inner lugs 20 and the outer ears 25 and the locking of the door The arrow F3 indicates the opening of the double door constituted by the cell door 5 and the container door 23. Door 10 3 is maintained in its state thanks to the seal 6 applied to the container door 23. The return to the initial position is effected by the reverse process. These sets can be made of different materials: stainless steel, aluminum and rigid plastic. For large volumes the body of the container is replaced by a flexible plastic bag. In order to respect the tolerances of the connection of the container to the cell flange, this makes it necessary to match the conditions of development and of obtaining the parts of the junction with the tolerances of the junction. In the case of single-use and high consumption containers, several thousand, these are made from a plastic blank 20 obtained by injection, then a machining resumption of all the parts related to the characteristics. of the junction: joint groove, seal range, and all elements with "toleranced" dimensions related to the mechanical and sealing characteristics, etc. Containers have been made in injection without resuming machining with 25 tolerances. injection, in accordance with standard NF T58-000 and according to the tolerance class chosen (normal, reduced and precision). For indication the tolerance deviation taking a reduced class is of the order, for a diameter 200mm, 2.3mm. We realize that the games are such that they do not allow the functional guarantee of such systems.
    [0004] The present invention therefore aims to overcome this disadvantage. OBJECT OF THE INVENTION The present invention relates to a system making it possible to overcome the radial clearance resulting from the drawbacks mentioned above, related to the injection tolerances. It allows the use of parts made by injection without being taken up in machining and to make a zero clearance connection of a container on a cell flange, this principle being independent of the number of ears. One could consider applying this principle to metal assemblies, which would in this case to widen the manufacturing tolerances, decreasing the rejects as well as their cost. According to its main feature, the inner lugs and the outer lugs of the container flange have a special shape which allows the recovery of the radial clearance and refocusing, on the one hand the container flange on the cell flange and on the other part of the container door on its container flange. The same is true for the container door with respect to the cell door, since the inner lugs of the container door have the same shape as the inner lugs of the container flange. For disposable container heads, the inherent elasticity of the material is sufficient, for multipurpose container heads, an elastic element is incorporated in the center of the special shape, which has the effect of compensating for the lack of elasticity of the remanence of the material over time.
    [0005] In fact, the main object of the invention is an assembly comprising a container with its container flange equipped with its container door, the container to be attached to an opening of another entity, the container flange having at minus one set of outer ears for attaching the container assembly comprising the container flange and one container door being of a material having a determined resilience, the outer lugs each have an oblong hole defining an outer portion; the outer ear of small width and which has an outwardly curved shape, which increases the overall external diameter of the container flange at the level of the outer ear, each outer portion thereby having a determined flexibility allowing it to bend inwardly 5 of the container flange under the constraint of the groove centering diameter 14 of the cell flange ule of said other entity, during his engagement in his ears. A further feature of the invention is that the container flange comprises an inner set of lugs for attaching this container flange to the container door, each having an elongated hole defining an inner portion of the inner lug. of small width and which has an inwardly curved shape which decreases the overall internal diameter of the container flange, each inner lug thereby having a specific flexibility allowing it to flex towards the outside of the container, under the constraint of centering diameter at the bottom of the container door, when mounted on its container flange.
    [0006] Preferably, the container door comprises an inner set of ears for attachment to the ears of the cell door of the other entity, each having an oblong hole defining an inner inward portion, identical in shape curved ear which decreases the inner diameter of these ears, each inner ear thereby having a specific flexibility allowing it to bend outward of the container door under the constraint of the groove centering diameter of the ears of the cell door of the other entity, when berthing the two entities. In a preferred embodiment of the invention, the domed portions of the outer and inner lugs are central with respect to their respective elongated holes and are shorter than the length of their respective elongated holes. In one advantageous application, the other entity is a sealed containment cell having a cell flange, the assembly being part of a double door type closure system. In a preferred embodiment of the invention, an outer wall 30 of the oblong hole of the outer ear has an arcuate shape corresponding to the curved shape of the outer portion of the outer ear, so that the outer portion has a constant width. In correspondence, preferably, an inner wall of the oblong hole of the inner lug has an arcuate shape corresponding to the curved shape of the inner part of the inner lug, so that this inner part has a constant width. It is advantageous to place an elastic element in each oblong hole of the inner and outer lugs to compensate for possible remanence of the material constituting the container flange.
    [0007] This element is elastically, preferably a leaf spring. LIST OF FIGURES The invention and its technical features will be better understood on reading the following description, accompanied by several figures respectively representing: FIG. 1, a traditional manufacturing assembly of a flange and a cell door; - Figure 2, a conventional manufacturing assembly of a container 20 comprising, inter alia, a container flange; - Figure 3, a container assembly connected to a flange assembly and corresponding cell door; - Figure 4, the assembly according to the invention comprising the container flange; FIG. 5 is a view from below of the assembly according to the invention using the container flange according to the invention; - Figure 6, the container flange according to the invention; - Figure 7, the container flange in perspective, seen from below; FIGS. 8A and 8B, in plan view and on a large scale, an outer lug of the container flange according to the invention; - Figure 9, in top view and on a large scale, an inner lug of the container flange according to the invention; - Figure 10, in profile perspective, the container door; - Figure 11, on a large scale, one of the inner lugs of the container door according to the invention; - Figure 12, on a large scale, one of the inner lugs of the container door in the use of the assembly according to the invention with a containment cell; - Figure 13, a compensation spring blade used together with the assembly according to the invention; - Figure 14, the same leaf spring in the free state; - Figure 15, the leaf spring in action. DETAILED DESCRIPTION OF AN EMBODIMENT OF THE INVENTION In principle, each outer lug has a domed shape whose outer diameter is greater than a value calculated from the injection tolerance class. For example, the injection tolerance is + or - 1 mm for a diameter of 200 mm and the functional tolerance is -0.1 to -0.2; in this case the rating on the ear will be between 200 and 202, for a nominal dimension of a diameter of 201 + or - 1 mm. In this case each ear must flex at most 1mm to compensate for this dimensional difference. The same reasoning is applicable to the inner lugs of the container flange and the inner lugs of the container door.
    [0008] With reference to FIGS. 4 and 5, the plastic container assembly 30 is obtained by injection without machining retouching by means of self-compensating lugs due to the intervals of the injection tolerances. It is composed of a container flange 31 comprising four outer lugs 32 to compensate for automatic play, four inner lugs 33 to catch play, a shell 34 attached to the rear of the container flange ending in a bead 35 in four bag holding sectors, a container door 36 comprising four outer lugs 37 and four inner lugs 38 with clearance clearance. A container body, represented by the bag subassembly flexible 26 comprising a retaining ring 28 at the top of the bag, the flexible bag 27 and its fixing collar 29 on the shell 5 of the container flange. Referring to Figure 6, the single container flange 31 its groove (39) receives the seal not shown, perspective view from above, to better appreciate the details. Figure 7 gives a better appreciation of the details, especially the four outer ears. FIGS. 8A and 8B show, in plan view and on a large scale, one of the outer lugs 32 of the container flange 31 engaged in one of the lugs 14 of the cell flange 10, during its axial engagement with the cell flange 10. The outer lugs 32 of the container flange 31 on the inlet slopes 15 undergo a radial reaction along the arrow F1 deforming the outer portions 40 of the oblong holes 41 along the deformed 42, recovering the injection tolerances and realizing an assembly without clearance. Indeed, each outer portion 40 has a curved shape 40A. Note during the rotation of the lock according to the arrow F2 of the container flange 31 on the cell flange the friction is low. The outer lugs 32 which self-center the container flange are in circumferential contact only on the sector of the deformed approximately one-third of the ear area. The arrow of the arc of this deformed corresponds to the absorption of the interval of the tolerance of injection added to those of the standard of the junction, parts concerned divided by two. Figure 8A shows the realization of the particular geometrical shape of an outer lug 32 of the container flange 31 for locking it to the lugs 14 of the cell flange secured to the wall 2 of the cell. The minimum number of ears is three. In the case here described preferentially they are four in number, nothing prevents a higher number of ears.
    [0009] The ear has a width, at its apex, corresponding to a first angle α distributed by half with respect to its axis X-X. It comprises the following sectors: a) A first sector at a second angle 131 which makes it possible to receive the inlet slope 45, see FIG. 7, which facilitates the engagement of the ears of the container flange 32 in those 14 of the cell flange 10 and gives the start of the oblong hole 41. b) A second sector at a third angle el defining the length of a first oblong hole 41, whose axis is shown by the line X1-X1. c) A third delimited area of the outer wall 41E by ab of diameter D1 corresponding to the inside diameter of the lugs 14 of the cell flange 10 less the injection tolerance of the container flange 31 increased by twice the value Y half of the diametrical tolerance interval of the junction between the cell flange 14 and the injected container flange 31. d) A fourth sector of the outer wall 41E delimited by b-d 15 corresponding to a concave shape whose center is symbolized by the axis X1-X1. The diameter D2 corresponding to the inside diameter of the lugs 14 of the cell flange 10 increased by the injection tolerance of the container flange 31 increased by twice the value of Y, Y corresponding to half the diametric tolerance interval. from the junction between the cell flange 14 and the container flange 31. This sector by point b 20 on a diameter D1 to come to point c on a diameter D2 in the axis X1-X1 to return to the point d on the diameter D1, determining a progressive curve, the shape of the oblong hole 41 follows this curve, the width of its recess can absorb the deformation 42 due to the flexion of the outer wall 40 under the effect of a force in the direction of the arrow F and the possibility of setting up a possible leaf spring 61 25 see Figure 14, to fight against possible remanence of the outer wall 40 of the oblong hole 41. On the section aa of Figure 8B, the chamfer 46 allows the pen The outer lugs 32 of the container flange 31 in the entry slopes 15 and then in the bottom of the lugs 14 of the cell flange 10 of FIG. 1, the chamfer 46 must be at least equal to or greater than the value of the deformed 42 at the point c of the outer wall 3036054 10 40 of the oblong hole 41. The compression of the points c on the cell flange creates a natural retention of the container flange on its cell flange helping the operator when the connection operation. It is possible to increase the spring effect of the outer wall of the oblong by accompanying it with a leaf spring according to the principle shown in Figures 13 to 15. Referring to Figure 9 showing in view From above and on a large scale, one of the inner lugs 33 of the free-flowing container flange 31, is found in the same principle the oblong hole 52 and its wall 53 allowing a deformed along the arrow F1 in contact with the bottom of the container. groove 49 of the outer lugs 37 of the container door 36. The principle is identical to that described for FIG. 8. In this FIG. 9 shows the realization of the particular geometrical shape of an inner lug 33 of the container flange 31 allowing the locking of its container door 36. The minimum number of ears is three, 15 in here preferentially described there are four, nothing prevents a higher number of ears. The ear has a width, at its apex, corresponding to the first angle distributed by half with respect to its axis XX, it comprises the following sectors: a) A first sector at a second angle 132 which gives the start of a second oblong hole 43. b) A second sector following a third angle 02 delimiting the length of the oblong hole 43, whose axis is represented by the line X1-X1. c) A third sector of the inner portion 44 delimited by ab of diameter D1 corresponding to the groove bottom diameter 49 inside the lugs 37 of the container door 36 increased by the injection tolerance of the container flange 31 and the container door 36, the whole being increased by twice the value Y corresponding to half the diametrical tolerance interval of the junction of the container flange and its container door. d) A fourth sector of the inner wall 44 delimited by b-d 30 having a convex shape 44A whose center is symbolized by the axis X1-X1 3036054 11 input. The diameter D2 corresponds to the diameter of the groove bottom 49 of the lugs 37 of the container door 36 minus the injection tolerance of the container door and the container flange 31, the whole being increased by twice the value of Y, Y corresponding to half of the diametrical tolerance interval of the junction between the container flange 31 and its container door 36. This sector starts from the point b on a diameter D1 to come to the point c on the diameter D2 in the axis X1-X1 to return to the point d on the diameter D1, determining a progressive curve, the shape of the oblong hole 43 follows this curve. The width I of its recess absorbs the deformation 48 due to the flexion of the inner wall 44 under the effect of a force in the direction of the arrow F1 F1 and the possibility of setting up a possible blade of spring 61 see FIG. 14, to combat any remanence of the inner wall 44 of the oblong hole 43. Referring to FIG. 10, showing in perspective of the profile the injection container door 36, the latter comprises four inner lugs 38 15 each having an oblong 52 with its inner wall 53 allowing deformation 54, see FIGS. 11 and 12, four outer lugs 37 and their locking pin 57 of the end of locking of the container door 36 on its container flange 31, the contact faces with the joints of the junction; the face 58 with the seal 6 of the cell door 5 and the face 59 with the seal of the container flange 31. The chamfer 47 allows the penetration 20 of the container door on the inner lugs of the container flange, this chamfer must be at least equal to or greater than the value of the deformed 48 at the point c of the inner wall 44 of the oblong hole 43. Referring to Figure 11 representing on a large scale one of the inner lugs 38 in the free state of the container door 36, the deformation 54 represented by the sector 60 of the inner wall 53 of the oblong hole 52 is well noted. For the detailed description of FIG. 11 concerning the inner lug and its oblong hole of the container, it should be based on the detailed description of Figure 9. Referring to Figure 12 representing a large scale one of the ears 7 of the cell door 5 locked on one of the inner ears 38 of the por With the container 36, abutting on the pin 55 of the cell door 5, the deformation 54 on the sector is observed to disappear, permitting the absorption tolerances of the container door 36 to be absorbed. 13 shows the spring blade 61 of flexural compensation of the wall 43 housed in the oblong hole 43 of the container door 36. It bears on the inside wall 431 of the oblong hole 43. When the assembly container is multiple use, the outer portion 40 must return to its original position despite possible remanence of the material in time. Referring to Fig. 14 showing the leaf spring 61 in the free state 10 for the inner ear and the spring leaf 62 symmetrical to the leaf spring 61 along the X-X axis for an outer ear. FIG. 15 shows the leaf spring 61 in action under the effect of the ear 7 of the cell door 5.
