- RIGID CONTAINER FOR A SOFT POUCH FOR CONTAINING A BIOPHARMACEUTICAL FLUID, ASSEMBLING A SOFT POUCH AND SUCH CONTAINER, AND METHOD FOR IMPLEMENTING A SAME
- the invention relates to the field of conditioning of biopharmaceutical fluids and more particularly to a rigid container for a 3D flexible pouch intended to contain such a biopharmaceutical fluid, a flexible 3D pouch intended for such a container, and a method of implementing such a container.
- Biopharmaceutical product means a product derived from biotechnology - culture media, cell cultures, buffer solutions, artificial nutrition liquids, blood products and derivatives of blood products - or a pharmaceutical product or, more generally, a product intended to be used in the medical field. Such a product is in liquid form, pasty, or possibly powdery. The invention also applies to other products but subject to similar requirements as regards their packaging.
- a 3D pocket is known for receiving such a biopharmaceutical product, which has a bottom end wall, an upper end wall, and a flexible side wall that can be in two extreme states - folded flat and unfolded deployed - and be deformed to pass from one to the other of these states or be in any intermediate state.
- the walls of the pouch made of plastics material such as polyethylene or a complex comprising polyethylene, define an internal space which, in the folded state, is of minimum volume and in unfolded and expanded state is maximum. This space is intended to receive the biopharmaceutical product for storage, processing, control.
- Such a flexible pouch, biocompatible, disposable can be large volume of at least 50 liters, up to 3,000 liters, or even more, which justifies it is called 3D.
- Such a pocket thus offers a large capacity while being easily stored.
- An example of such a pocket is described in international application WO00 / 04131.
- Such a 3D flexible pouch when filled with biopharmaceutical product must be placed in a rigid container which holds it from the outside. This requirement is particularly important in the case where the pocket filled with biopharmaceutical product has to be moved and transported by road, train or air. Indeed, there is the risk that the integrity of the pocket is affected by shocks, efforts, deformations ..., which can in turn affect the biopharmaceutical product it contains.
- such a rigid container comprises a lower transverse wall and an erected lateral peripheral axial wall limiting an upper transverse opening access to a housing defined by the inner faces of these walls, adapted to receive the pocket containing the biopharmaceutical fluid which comes to apply against these internal faces.
- Document EP-A-1012073 describes such a container, furthermore provided with a protective and containment wall capable of being placed transversely in the housing of the rigid container, having dimensions such that the transverse clearance between its outer peripheral free edge and the inner face of the side wall facing the rigid container is limited.
- Such a wall of protection and contention is able to be applied with a certain axial force against the outer face of the upper end wall of the pocket and to be fixedly held in this position by holding means in the active state. , supported by a system of screw jacks on removable spars located in this case in the upper part of the rigid container.
- the axial height of the height of the jack system determines the height of travel on which can be the plate protection and contention. Either this size is chosen restricted, for the advantages that it provides with the disadvantage that the plate of protection and contention can be implemented with a completely filled pocket is, if one wants that the race of the contention plate is the largest possible, for example because the pocket could be only partially filled, the cylinder system necessarily has a large axial size in height, which is a source of inconvenience, the lack of compactness being a problem. serious handicap for travel and transportation.
- the flexible pouch Since the flexible pouch is of maximum capacity and having regard to the very nature of its contents - a biopharmaceutical product - it must be possible to use the pouch without having to fill it completely, and with variable volumes. continuously.
- this situation poses another problem when the flexible pouch partially filled with biopharmaceutical product has to be moved and transported, especially over a large distance and under conditions such that it is prone to sudden movements or to significant accelerations, because the high inertia of the content of the flexible pouch then creates a movement of imbalance of the pocket and its contents that can affect the integrity of the pocket and therefore its contents.
- the document WO 2006/070010 describes a method for packaging a viscous product contained in a flexible pouch with a capacity greater than 50 liters, preferably greater than 100 liters, in volume units with a capacity of less than 50 liters, preferably less than 50 liters. 100 liters.
- This flexible bag has an evacuation passage of the viscous product located on its upper end wall.
- This flexible bag, filled with the viscous product, is placed in a rigid container having a lower transverse wall forming a pressure piston, mounted to slide vertically and driven by a jack system placed below this lower transverse wall and above a fixed lower floor.
- This container also comprises a fixed top cover, reversible, provided with a viscous product conveying orifice to a conditioner in a smaller volume, in communication with the discharge passage of the flexible bag.
- the arrangement according to WO 2006/070010 is for viscous products, but not for biopharmaceuticals. It is not intended to preserve the integrity of the pouch and its contents, and does not include the case of a pouch partially filled with its contents that can be moved and transported a significant distance and / or under conditions to generate sudden movements or accelerations. This arrangement is not more concerned with the compactness of the rigid container. Finally, this arrangement imposes evacuation from above, whereas in the case of 3D bags for biopharmaceutical products, evacuation is most often from below. In the arrangement according to WO 2004/074164, this disadvantage is overcome, but not the others, in particular the lack of compactness. Similar devices are described in GB-A-2159583 and BE-A-539623.
- a container comprising, on the one hand, a tray inside which is placed an envelope and, on the other hand, a holding plate which comes to rest on the envelope when this one is not completely filled or that its dimension in height is lower than that of the tank.
- the holding plate is then held inside the tray by means of pressure screws cooperating with threaded recesses arranged in the inner wall of the tray, as shown in Figure 4 of this document.
- a disadvantage of this device is that it does not preserve the integrity of the envelope regardless of its filling volume. Indeed, the position of the holding plate necessarily depends on the position of the threaded recesses. Therefore, the position of the holding plate relative to the bottom of the tray can be modulated continuously as a function of filling the envelope.
- EP-A-0 456 403 discloses a container for a flexible pouch filled with a pharmaceutical product.
- a support element is attached to the upper face of the flexible bag to move the upper face to the same level as the product when a portion of this product flows from the flexible bag.
- Such an embodiment has, like the previous embodiments, several disadvantages.
- the use of a support element is insufficient to prevent the pharmaceutical product contained in the flexible pouch from wobbling inside thereof when the container is set in motion.
- the sole weight of the support element does not provide a holding force sufficient to counter the forces exerted on the flexible bag when the product it contains moves and agitates.
- a rigid container for flexible pouch 3D of large capacity which, on the one hand, is able to preserve the integrity of the bag and its contents, even when the bag is only partially filled with biopharmaceutical product, when the bag thus filled is moved and transported a significant distance and / or under conditions that are capable of generating sudden movements or significant accelerations, and which, on the other hand, is compact.

- the holding means 16 are arranged so as to be applied at any desired location of a continuous zone 17 of the inner face 4a of the side wall 4, and this in a continuous variation.
- This zone 17 is extended in the vertical axial direction, in particular over all or substantially the entire height of the rigid container 1, so that the compression wall 15 can be placed in the housing 7 at any desired distance - continuously varying - from the lower transverse wall 3 or at any desired distance from the upper transverse opening 6.
- FIG. 5 illustrates three particular different possible positions in height of the contention plate 15, corresponding to three different volumes of the biopharmaceutical product contained in the flexible pouch 3D, 2, namely a volume V1, a volume V2 greater than V1, and a volume V3 greater than V2.
- the compression wall 15 can be applied and maintained with a certain axial force against the upper outer face 12a of the transverse upper wall 12 of the pocket 3D, 2, whatever the degree of filling of this, this degree of filling can vary continuously.
