    Method of manufacturing a sealed container
    The present invention relates to sealed containers in the pharmaceutical or biotechnological field.
    More particularly, the invention relates to sealed containers used in sealed assemblies between a sterile enclosure such as an insulator and one or more of said containers. In this field, it is known to use a sterile enclosure comprising a plurality of doors, and to connect at these doors containers, themselves equipped with doors. The doors are open following the connection between the sterile enclosure and the outer container, to allow a transfer of objects contained in the container to the sterile enclosure, and possibly in the opposite direction.
    Methods of manufacturing sealed containers for biopharmaceutical applications, such as the container described in FR2721289, are already commonly known. In particular, it involves mounting a sealed assembly by assembling a pocket comprising a wall and an access opening to a connector provided with a door, the other access opening of the pocket being intended to be closed. A known method of manufacture of such an assembly for such a container is by inserting the thickness of the wall of the pocket at its access opening between the connector and a complementary piece which clamps the previous assembly. However, this type of container is intended to be subject to significant constraints, and a risk of loss of sealing at the assembly, or weakening of the material constituting the pocket may eventually lead to a rupture, exists always. We are therefore seeking to reduce such risks for the ever more demanding applications targeted in the biopharmaceutical field.
    The search for another solution to ensure a better seal has led to consider a welded connection between the pocket and the connector. However, such a method of assembly poses a problem in terms of the usual materials constituting these components, which are not sufficiently compatible for a welded joint to be possible (temperature resistance) and guarantee better performance.
    We are therefore looking for an alternative solution to these sealing assembly manufacturing processes. For this purpose, in the method of manufacturing a sealed assembly according to the invention there is provided a pocket comprising a flexible film wall, the wall of said pocket defining an interior volume of said pocket, said pocket having two opposite ends, a first access opening at the first end adapted to be able to communicate the interior volume of the pocket with the outside of the pocket, a second access opening to the second end adapted to be able to communicate the interior volume of the pocket with outside the pocket, there is provided a connection system, the connection system comprising a connector adapted to be mechanically connected to a complementary connector of a sterile enclosure for sterile communication between the bag and the enclosure, the connector comprising a pocket attachment portion, the connection system further comprising a surmoulage surmou 1 to the fastening portion, the manufacturing method further comprising the following steps of positioning the wall of the pocket facing the overmoulding at the first access opening, the fixing portion surrounding a passage space between the pocket and the enclosure at said first access opening, weld the wall of the pocket to the overmoulding continuously closed along the first access opening.
    In the case of such a manufacturing process, the overmolding, chosen from a suitable material, allows the welding of the pocket wall on said overmolding, for a good seal of the container thus manufactured. In addition, the sealed container thus manufactured can be sterilized by steam or gamma radiation.

    The present invention relates to sealed containers and their manufacture for pharmaceutical or biotechnological type applications requiring to limit or avoid any contamination, including by particles from the external environment.
    It will typically be to obtain a pocket whose contents must be isolated from the external environment, assembled to another enclosure, such as an insulator, for a sterile transfer between the pocket and the enclosure. A typical application will be to use such a container to transfer sterile packaging material or syringe caps from a pouch in which they are initially contained and sterilized to an insulator.
    Figure 1 shows a sealed container. Said container comprises a sealed assembly whose second access opening 20 is sealed.
    More specifically, the sealed assembly comprises a pocket 1 comprising a flexible film wall 8, the wall 8 of said pocket defining an interior volume V of said pocket, said pocket 1 having two opposite ends, a first access opening 10 adapted to ability to communicate the interior volume of the pocket with the outside of the pocket at the first end, a second access opening 20 adapted to be able to communicate the interior volume of the pocket with the outside of the pocket at the second end . The container also comprises a connection system 9 which has a connector 21 comprising a fixing portion 210 and an overmoulding 40 overmolded on the fastening portion 210. The wall of the bag is positioned opposite the overmoulding at the first opening. access 10, the wall of the bag being welded to the overmolding 40. The second access opening 20 of said pocket 1 is sealed.
    Said assembly can be sealed at the connector 21.
    Said assembly may in particular be connected to a complementary connector of a sterile enclosure, such an assembly between the connectors allowing sterile communication between the contents of the bag 1 and the enclosure 11. The attachment portion 210 is at the level of the access opening of the pocket 1 and surrounds a passage space 24 between the pocket 1 and the enclosure 11 at the access opening 10. The assembly thus formed can for example be removable and transportable, for example example of single use, the assembly being small, the bag being flexible, which limits the size for the transport and delivery of these containers.
    The second access opening 20 is then closed in a leaktight manner, thus forming a pocket, after, in particular, introducing the products into the pocket 1. According to a first variant, the second access opening 20 is closed off by a closure surface 2, the closure surface 2 being adapted to attach to the wall of the pocket 1 at its second access opening 20 (Figure 1b). In essence, each point of the circumference of the closure surface 2 is fixed at a point of the circumference of the second access opening 20 of the pocket 1, ideally bijective. In a second variant, the second access opening 20 is closed by a weld on itself of the wall of the pocket 1 at its second access opening 20 (Figure 1a). Essentially all the points of the circumference of the closure surface 2 are welded together ideally a point. In use, the internal volume V of said pocket 1 is filled with the material to be introduced into the chamber 11, such as, for example, elements such as syringe plugs. The contents of the container thus formed is then for example sterilized with gamma rays.
    Sterilization can for example be made through the wall 8 of the pocket. Part of the wall of the pocket 1 may for example be Tyvec® which is a vapor permeable material. The pocket is for example in this case then over-packaged to ensure its sterility until use. In the case where the second access opening 20 is closed by a closure surface, the sterilization can be made through the closure surface 2 which can for example be made of Tyvec®.
    More specifically in a first embodiment illustrated in FIG. 2, the connector 21 comprises a radially outer surface 22 oriented radially outwardly of the connector 21, and the overmolding 40 comprises a radially inner surface 41 and an opposite radially outer surface 42. on the radially inner surface 41 of the over-molding 40. In addition, the pocket 1 comprises an inner surface 6 facing towards the internal volume V. In the receptacle thus formed, the radially outer surface 22 of the connector 21 is opposite the radially inner surface 41 overmolding 40, such as during the positioning step overmolding 40 facing the wall of the pocket 1, the radially outer surface 42 of overmolding 40 is also compared with the inner surface 6 of the pocket 1. Thus at the first access opening 10 of the bag 1, the passage between the bag 1 and the outside is constituted the superposition, going from the inside to the outside, of the thickness of the connector 21 at its fixing portion, the thickness of the overmoulding and the thickness of the wall of the pocket 1.
    In particular, the wall 8 of the pocket is made of flexible film and welded to the overmolding 40 in a continuous closed manner along the first access opening 10.
    In another embodiment illustrated in FIG. 3, said connector 21 comprises a radially inner surface 23 oriented radially towards the inside of the connector 21, and the overmoulding 40 comprises a radially inner surface 41 and a radially outer surface 42 opposite to the radially inner surface 41 of overmolding 40. In addition the pocket 1 comprises an outer surface 7 opposite to the inner surface 6. In the container thus formed, the radially inner surface 23 of the connector 21 is opposite the radially outer surface 42 of the overmoulding 40, such as during the step of positioning the overmolding 40 facing the wall 8 of the pocket 1, the radially inner surface 41 of the over-molding 40 is also placed in register with the outer surface 7 of the wall 8 of the pocket 1. Thus at the level of the first access opening of the pocket 1, the passage between the pocket 1 and the outside consists of the superposition, going from inside to outside, the thickness of the wall of the pocket 1, the thickness of the overmoulding and the thickness of the connector 21 at its fixing portion.
    In particular, as illustrated in FIG. 4, the fastening portion 210 of the connector 21 can comprise a body 70 with a projecting element 202 that extends radially from said main body 70. Said projecting element 202 is adapted to be encapsulated in the Overmolding 40. The thickness of the body at the projecting element 202 is typically two to three times greater than that of the body at the level where there is no protruding element.
    The manufacturing method of the assembly illustrated in FIG. 5 comprises the following steps in the order: positioning the wall of the pocket 1 facing the overmolding 40 at the level of the first access opening 10, the overmolding 40, worn by the connector 21, being for example inserted into the pocket 1 by its access opening 10, near the access opening 10 of the pocket 1, weld the wall of the pocket 1, at its first opening access, overmoulding 40, continuously closed along the first access opening.
    The manufacturing method also comprises a step of obtaining overmolding 40, illustrated in FIG. 6. In this step of obtaining overmolding 40, a molding element 3 is provided adapted to at least partially surround the fixing portion 210. The molding element comprises for example two semicircular cavities 31 and 32 and a tubular section 33 used to contain the material. Also provided is a molding product 4 in a material adapted to be welded to said product with the flexible film wall of the pouch.
    The method includes at least the following three steps. It is a question of at least partially surrounding the fixing portion 210 of the connector 21 by the molding element 3 so as to define a closed cavity between the fixing portion 210 and the molding element 3. It is then a question of pouring or injecting the molding product 4 between the fixing portion 210 and the molding element 3. It is finally a question of removing the molding element 3, releasing the overmolding 40 on at least one part of the fastening portion 210. The piece 21 is for example obtained by injection molding using a molding element 30.
    In the case where the fastening portion 210 of the connector is for example annular, the molding element 3 is also annular such that it surrounds the thickness of the connector 21 at its fastening portion 210. The overmolding 40 thus obtained is then also annular. The weld is then a circular weld.
    Such a manufacturing method will be used in particular to assemble a plastic film bag with a connector 21 made of polycarbonate (PC) or acrylonitrile butadiene styrene (ABS) or polyvinylidene fluoride (PVDF) or polybutylene terephthalate (PBT). Such materials for the connector 21 will be rigid that can withstand the locking forces of the second connector and resistant to different treatments associated with steam sterilization (at temperatures below 125 ° C), gamma or ethylene oxide.
    The plastic film may be in particular polyethylene (PE), high density polyethylene (HDPE) or low density polyethylene (LDPE).
    The molding product 4 will then be for example polyethylene (PE), high density (HDPE) or in the form of thermoplastic elastomer (TPE) or may also be thermoplastic elastomer or polypropylene or polyvinylidene fluoride (PVDF). Overmolding 4 in such materials is poorly resistant to sterilization (<125 ° C) and will also tend to deform at weld working temperatures above 120 ° C, its mechanical strength then being insufficient at these temperatures, but will not not to melt when the temperature rises when it is mounted on the connector which will "cash" then its deformation.
    However, it is demonstrated by the tests that the welding of the plastic film on the overmolding is resistant to gamma sterilization or steam sterilization.
    To perform the welding, the film and the overmoulding will begin to melt at almost the same time, therefore in temperature ranges close to 120 ° (far from the soldering temperatures of the materials chosen for the connector 21, which is in the order of 200 °) .
    Advantageously consider the case where the connector 21 is polyvinylidene fluoride (PVDF) and overmolding 40 is high density polyethylene (HDPE) or thermoplastic elastomer (TPE); the connector 21 is made of polycarbonate (PC) and the overmolding 40 is made of high-density polyethylene (HDPE) or thermoplastic elastomer (TPE); the connector 21 is made of acrylonitrile butadiene styrene (ABS) and the overmolding 40 is high density polyethylene (HDPE) or thermoplastic elastomer (TPE); the connector 21 is polybutylene terephthalate (PBT) and the overmoulding 40 is high density polyethylene (HDPE) or polyvinylidene fluoride (PVDF).
    In a particular embodiment illustrated in FIG. 7, the connector 21 comprises, for example, a first door 14 adapted to equip the access opening 10 of the pocket 1. The first door 14 comprises a flange-like frame 200, the fixing portion 210 forming at least part of the flange 200. Thus the first door 14 can be used to seal the container.
    It is then possible to form a sealed assembly by assembling the sealed container described above with an enclosure 11. Such a temporary assembly may, for example, make it possible to ensure a clean transfer of a biopharmaceutical content between the pocket thus formed and the enclosure 11. The enclosure 11 also comprises, for example, a second door 12 comprising a flange-like frame 201, said second door 12 being adapted to equip an access opening 13 of this enclosure 11 and being complementary to the first door 14.
    More specifically, each door may be circular, the diametrical dimension of the second door 12 being greater than the size of the opening in the flange 200 for the first door. Each door is provided with sealing means with its flange, such as a compressible annular seal carried by the flange and cooperating with a bearing of said door. Each door is also associated with locking means in the closed position on its flange. To position the flange 200 of the first door relative to the flange 201 of the second door, the flange 201 of the second door is secured to a plurality of longitudinal fingers projecting outwards and adapted to cooperate with circular notches in the periphery. of the flange 200 of the first door. In the absence of any transfer, each door is locked on its flange. When it comes to transferring the contents of the bag to the enclosure 11, the flange of the first door 200 is brought against that of the second door 201 where it is positioned by the fingers and finally by engagement of a boss central of the second door in a recess of the first door. The two flanges are then locked together in the so-called coupled position and then the two doors are unlocked to allow communication between the pocket and the enclosure 11. For example, one of the enclosures is for example constituted by an insulator and the pocket contains one or more objects or a load to be transferred into the coupled position by the passage thus established between the two enclosures, for example to supply the clean room with components or products required for manufacture or production in progress in the clean room, or conversely to evacuate waste or products of said clean room. The pouch can contain sterile objects, caps, hoses, syringe pistons.
    The bag may in particular be a raft bag © as shown in FIG. 8. In this case, a pipe 100 of an aseptic connector 102 passes sterilely through the wall 8 of the bag 1 and via a connector 101. then be inserted sterilely into the chamber 11 to form a sterile line between an end of the pipe 100, through which products can be entered, and the enclosure 11 to which the products can be routed.
    In another particular embodiment, the overmoulding is assembled on one side of the plastic film by adjusting the diameter of the hole with the elasticity of the film used for mounting the connector called flat mounting.
