Description

Title of the invention: Sealed connection device for transferring objects with improved spillage Technical field

[0001] The invention relates to the sealed transfer of objects from a sealed container to a cell, with a double-door connection system. STATE OF THE PRIOR ART

[0002] In various industrial sectors, tasks are carried out in a confined atmosphere, for example to protect the environment from radioactivity or toxicity, or to carry out these tasks in an aseptic atmosphere, or both simultaneously.

[0003] The transfer of objects from a container to a cell without breaking the seal is ensured with a double-door connection device, known for example from documents FR2695343 and US8950624.

[0004] Such a device is for example used for packaging medicines. A filling line is then installed in the cell, and small objects such as bottle caps are transferred into the cell to supply this line.

[0005] In such a device, the cell is equipped with a flange closed on the inside by a door mounted on a hinge fitted to this flange, and the container is for example a bag whose mouth is provided with another flange fitted with another door.

[0006] The connection consists of engaging the container flange in that of the cell, and pivoting it on itself, which has the effect of:

[0007] - secure the two flanges to each other by engaging a first connection at bayonet which is a flange-flange connection;

[0008] - secure the two doors to each other by engaging a second connection to bayonet which is a door-to-door connection;

[0009] - detach the container door from its flange by disengaging a third bayonet connection which is a flange-door connection.

[0010] After connection, the cell door is pivoted inwards to open it: the container door then being rigidly secured to that of the cell by the door-door connection, it is taken with the cell door to extract it from the container flange.

[0011] When the objects have been transferred, the cell door can then be folded back against this opening. The container door, which is integral with the cell door, then returns to its place in the cell flange.

[0012] The container is then rotated on itself in the opposite direction, which has the effect of:

[0013] - secure the container door to the container flange;

[0014] - separate the container door from the cell door;

[0015] - separate the container flange from the cell flange.

[0016] In such a device, the container flange has internal ears projecting radially inwards and being regularly spaced at its internal circumference. The container door has external ears intended to cooperate with these internal ears to form the flange-door connection.

[0017] At the end of the transfer, it happens that undischarged objects remain positioned between two internal ears of the container flange, so that they block the closing of the assembly consisting of the cell door secured to the container door because they constitute an obstacle to the passage of an external ear of the container door.

[0018] In addition, for reasons of container cleanliness, it becomes necessary to limit as much as possible the contact between the elements of the container and the components transported in the container. Indeed, in the solutions present on the market, the containers are composed of a flexible plastic bag connected to a connector which will be essentially made of plastic. The components therefore come into contact with the bag on the one hand and parts made of injected plastic material.

[0019] The pockets, due to their manufacturing process, are at a sufficient level of cleanliness, on the other hand the plastic parts require cleaning and can present sources of pollution such as injection points or the joint plane lines of the tooling.

[0020] The invention makes it possible to have the pocket covering the entire flow area of ​​the components, thus protecting the transported components from the plastic parts constituting the container flange.

[0021] In storage, the components can only touch the rear face of the container door, which limits the risk of pollution by taking particular care of this surface.

[0022] Advantageously, the flexible bag replaces the flexible sleeve to allow easy flow for transfer systems mounted on vertical walls, and automated, for which the manual operation of extracting this flexible sleeve is no longer desired.

[0023] The construction of the two-part flange allows for a rigid material, resistant to the usual sterilization processes: sterilization by gamma radiation or X, by steam sterilization, ethylene oxide sterilization, for the connection part which will bond with the insulator and a material which will be advantageously weldable with the flexible bag for the internal insert. This construction of the container flange in two parts advantageously allows: • To use the most suitable material for the function to be performed • To allow the internal passage to be completely covered by the flexible bag, the bag being folded and fixed to the outside of the internal insert, then this assembly being brought back into the container flange

[0024] The front face of the internal insert also allows the integrated fall to be docked with the line in order to create a flow zone.

[0025] The aim of the invention is to provide a solution to overcome these drawbacks. Statement of the invention

[0063] As a preliminary, an axial direction and a radial direction which is orthogonal to the axial direction are defined.

[0064] With reference to figures 1 to 3, a wall 1 of a cell is equipped with a cell flange 2 in which is engaged a container flange 3 provided with a container door 4. The container 80, extends in particular in the extension of the flange 3, outside the cell, and is, here, a flexible bag 81 made from a plastic film which defines a wall 82 of the bag 81. The assembly consisting of the container flange 3 and the container door 4 constitutes a closure 70 of the container 80 on which it is attached.

[0065] The container flange 3 has four internal ears, also called internal tabs, regularly distributed at 90° around a central axis AX of the flange 3. Two of these internal ears, marked 6 and 7, are visible in [Fig. 1], these internal ears protruding radially towards the axis AX of a cylindrical internal face 8 of this flange 3.

[0066] In this text, the terms "inner" or "internal" and "outer" or "external" are used with reference to the position or orientation relative to the longitudinal axis of the flange 3.

[0067] The container door 4 is mounted to rotate relative to the container flange 3 around a first axis of rotation 01, here coincident with the axis Ax. The container door 4 which can occupy a closed state to close a central opening 5 of the container flange 3 and an open state to release the central opening 5 comprises four external ears, also called external legs, regularly distributed at 90° around the axis AX, two of these external ears, marked by 9 and 11 being visible in [Fig.l]. These external ears protrude radially from the circular external periphery of the door 4 to be able to engage each between two contiguous internal ears of the flange 3, as in the configuration of [Fig.l]. The transition of the container door 4 from one state to the other is done by a rotation of the container door 4 relative to the container flange 3 around the axis 01.

[0068] The cell flange 2 is provided on the inside of the cell with a hinge 13 on which is mounted a cell door 14 visible in [Fig. 2]. This cell door 14 opens towards the inside of the cell to release the central opening 16 of the flange 2, as in the configuration of [Fig. 2]. This door 14 can also occupy a folded position over the opening 16 to close it, which corresponds to the configuration of [Fig. 1]. As visible in Figures 1 and 2, the hinge 13 extends along an axis AY which is parallel to the wall 1 and which is here oriented vertically.

[0069] The central opening 5 of the container flange 3 is, here, a second central opening, and the central opening 16 of the cell flange 2 is a first central opening.

[0070] The connection of the container flange 3 consists of engaging its end in the cell flange 2, then pivoting it around the axis AX by means of two gripping handles 17 and 18 of this flange 3 which extend radially.

[0071] This rotation has the effect of disengaging a first bayonet connection, called the door flange, corresponding to the internal lugs 6, 7 and external lugs 9 and 11 to separate the container door 4 from the container flange 3. This first bayonet connection thus constitutes a means of blocking and releasing the container door 4.

[0072] This rotation also has the effect of engaging a second bayonet connection, called a door-carrier, not visible, to secure the container door 4 to the cell door 14. This second bayonet connection thus constitutes a means for securing and detaching the container door and the cell door.

[0073] This rotation also has the effect of engaging a third bayonet connection, called flange-flange, not visible in the figures, to secure the two flanges. This third bayonet connection thus constitutes a means of coupling the two flanges.

[0074] Once the container flange 3 is connected to the cell flange 2, opening the cell door 14 allows the central opening 16 to be released, taking with it the container door 4, which corresponds to the situation in [Fig.2].

[0075] As seen in [Fig.3], the container flange 3 delimits a transfer path 30 which connects a supply end 31 of the container flange 3 and a supply end discharge 32 of the container flange 3. The end 32 opens opposite the central opening 5 which is closed by the container door 4. The container door 4 thus extends in the immediate vicinity of the discharge end 32. The wall 82 defines an interior volume 83 of the bag 81 and comprises a first wall portion 84 which extends outside the transfer path 30 and a second wall portion 85 which extends into the transfer path 30. The second wall portion 85 comprises an orifice 86 which defines a free edge 87 (here of substantially circular shape) which is attached and welded to an inner face 33 of the transfer path 30 - here at the discharge end 32. The first wall portion 84 corresponds substantially to a bottom of the bag 81 and the second wall portion 85 corresponds to a top of the bag 81.

[0076] The bag 81 contains objects 21, here vaccine bottle lids.

[0077] When using the container 80, the objects 21 which rest, after emptying the bag 81, in the transfer path 30 - that is to say in a volume partially delimited circumferentially by the second wall portion 85 - are likely to hinder the closing of the door 4. A raising of the bottom of the bag 81 - here carried out by moving the first wall portion 84 upwards according to the representation of [Fig. 3] - causes a raising of the second wall portion 85 by rotation of the latter around the free edge 87. The new position 85' of the portion 85 of the bag 81 is partially represented in broken lines in [Fig. 3]. The objects 21 which rest on the second portion of wall 85 placed in this position 85' are then drawn by gravity through the opening 5. Nothing more prevents the closing of the door 4 and it can be closed again.

[0078] The manufacture of the closure 70 and the container 80 will now be detailed with reference to figures 4 to 6. The container flange 3 comprises a first flange element 40 and a second flange element 50. The first flange element 40 comprises a tubular body 41 in the form of a right cylinder with axis Ax defining an internal volume 42 of the first flange element 40. The internal volume 42 has a first internal diameter D42. The tubular body 41 carries at its first end 43 radially external ears 44 of the second bayonet connection.

[0079] The second element 50 comprises a first section 51 in the shape of a straight cylinder and which defines the discharge end 32 of the container flange 3.

[0080] The first section 51 comprises a distal end 52 which describes a circle of outer diameter D52 substantially smaller than the diameter D42.

[0081] The first flange element 40 comprises a first crown 45 extending in external projection in a first radial plane Prl to define a first assembly flange 46. The flange 46 comprises a groove 47 for receiving a sealing O-ring 48. The flange 46 extends near a second end 49 of the flange element 40 opposite the first end 43.

[0082] The second flange element 50 comprises a second crown 53 which projects externally from the first section 51 and which extends in a second radial plane Pr2 located near the supply end 31 to define a second assembly flange 54.

[0083] The flange elements 40 and 50 are advantageously produced by thermoplastic injection.

[0084] The manufacture of the container 80 according to the first embodiment of the invention takes place as follows.

[0085] According to a first step shown in [Fig.5], the free edge 87 of the bag 81 is engaged in the first section 51 from the feed end 31 until the free edge 87 is in the immediate vicinity of the distal end 52. The edge 87 is then welded to a radially internal face 51.1 of the first section 51. In this configuration, the first wall portion 84 extends outside the first section 51 and the second wall portion 85 extends inside the first section 51.

[0086] According to a second step, the distal end 52 of the second flange element 50 is engaged through the end 49 of the first flange element 40. The second element 50 is then slid relative to the first element 40 along the axis Ax until the first assembly flange 46 comes into contact with the second assembly flange 54. An assembly collar 60 is made up of two half-collars 61 and 62 articulated at their first ends and connected by screwing at their second ends. The collar 60 has a groove 63 for receiving the flanges 46 and 57. The profiles of the flanges 46 and 54 as well as the profile of the groove 63 are arranged so that screwing the half-collars 61 and 62 together tightens the assembly flanges 46 and 57 against each other, compressing the seal 48. The container 80 shown in [Fig.6] is then obtained.The second flange element 50 extends inside the internal volume 42 of the first flange element 40. As seen in [Fig.6], the collar 60 has an outside diameter D60 substantially equal to an outside diameter D44 of the ears 44. After filling, the door 4 and its seal are installed in front of the opening 5 to obtain the closed container 80 of [Fig.3].

[0087] Elements identical or analogous to those previously described will bear a numerical reference identical to this in the following description of a second, third and fourth embodiment of the invention.

[0088] According to a second embodiment of the invention shown in Figures 7 to 9, the closure 70 comprises a clamping ring 71 - here a clamping ring 71 whose section is substantially L-shaped - and which has a clamping face 72. The clamping face 72 extends in a third radial clamping plane Pr3. The clamping ring 71 is attached by gluing to a radially internal face 41.1 of the tubular body 41, which makes it possible to easily adapt the flange 3 of the first embodiment to this second embodiment.

[0089] According to the second embodiment, the distal end 52 of the second flange element 50 comprises a housing 55 for receiving a seal 56 - here an O-ring.

[0090] The manufacture of the container 80 according to the second embodiment of the invention takes place as follows.

[0091] According to a first step, the free edge 87 of the bag 81 is engaged in the first section 51 from the supply end 31 until the free edge 87 is in the immediate vicinity of the distal end 52. The free edge 87 is then moved radially so that the wall 82 extends opposite the distal end 52 of the second flange element 50. Finally, the free edge 87 is then brought radially towards the supply end 31 of the second flange element 50. Thus, the free edge 87 extends opposite a radially external surface 51.2 of the first section 51 which defines the transfer path 30 ([Fig.9]).

[0092] In this configuration, the first wall portion 84 extends outside the first section 51 and the second wall portion 85 extends inside the first section 51.

[0093] According to a second step, the distal end 52 of the second flange element 50 is engaged through the end 49 of the first flange element 40. The second element 50 is then slid relative to the first element 40 along the axis Ax until the first assembly flange 46 comes into contact with the second assembly flange 54. In this configuration, the distal end 52 of the second flange element 50 extends opposite the clamping face 72 of the ring 71 and the seal 56 presses the wall 82 against the clamping face 72.

[0094] The tightening of the assembly collar 60 causes the wall 82 to be tightened between the seal 56 and the tightening face 72.

[0095] According to a third embodiment of the invention shown in figures 10 to 12, the closure 70 comprises a clamping ring 71 - here a clamping ring 71 whose section is substantially L-shaped - and which has a clamping face 72. The clamping face 72 extends parallel to the axis 01 and comprises an annular housing 73 for receiving a seal 74 - here an O-ring. The clamping ring 71 also comprises an appendage 75 which projects radially inside the face 72.

[0096] According to this third embodiment, the distal end 52 of the second flange element 50 comprises a housing 55 for receiving the seal 74.

[0097] The manufacture of the container 80 according to the third embodiment of the invention takes place as follows.

[0098] According to a first step, the free edge 87 of the bag 81 is engaged in the first section 51 from the supply end 31 until the free edge 87 is in the immediate vicinity of the distal end 52. The free edge 87 is then moved radially so that the wall 82 extends opposite the distal end 52 of the second flange element 50. Finally, the free edge 87 is then brought radially towards the supply end 31 of the second flange element 50. Thus, the wall 82 extends opposite the housing 55 of the seal 74 and the free edge 87 extends opposite a radially external surface 51.2 of the first section 51 which defines the transfer path 30 ([Fig. 12]). In this configuration, the first wall portion 84 extends outside the first section 51 and the second wall portion 85 extends inside the first section 51.

[0099] According to a second step, the seal 74 is installed in its housing. In doing so, the seal 74 comes to bear on the wall 82. The ring 71 is then engaged on the distal end 52 of the second flange element 50 and the latter is translated relative to the second flange element 50 until the appendage 75 comes into contact with the distal end 52. At the end of this step, the seal 74 is in place in the housing 73 and the clamping ring 71 exerts a radial clamping force on the wall 82 against the radially external surface 51.2 of the first section 51.

[0100] According to a third step, the distal end 52 of the second flange element 50, equipped with the clamping ring 71, is engaged through the end 49 of the first flange element 40. The second element 50 is then slid relative to the first element 40 along the axis Ax until the first assembly flange 46 comes into contact with the second assembly flange 54.

[0101] The assembly collar 60 is then mounted and tightened on the first assembly flange 46 and the second assembly flange 54.

[0102] According to a fourth embodiment of the invention shown in figures 13 to 15, the closure 70 comprises a clamping ring 71 - here a clamping ring 71 of truncated cone section which has a clamping face 72 provided with two fir-tooth reliefs 76 and 77. The clamping ring 71 also comprises a radial appendage 78.

[0103] According to this fourth embodiment, the distal end 52 of the second flange element 50 comprises two housings 58 and 59 arranged to cooperate with the reliefs 76 and 77.

[0104] The manufacture of the container 80 according to the third embodiment of the invention takes place as follows.

[0105] According to a first step, the free edge 87 of the bag 81 is engaged in the first section 51 from the feed end 31 until the free edge 87 is in the immediate vicinity of the distal end 52. The free edge 87 is then moved radially so that the wall 82 extends facing the distal end 52 of the second flange element 50. Finally, the free edge 87 is then brought back radially towards the supply end 31 of the second flange element 50. Thus, the wall 82 extends opposite the two fir-tooth reliefs 76 and 77 and the free edge 87 extends facing a radially external surface 51.2 of the first section 51 which defines the transfer path 30 ([Fig. 12]). In this configuration, the first wall portion 84 extends outside the first section 51 and the second wall portion 85 extends inside the first section 51.

[0106] According to a second step, the ring 71 is engaged on the distal end 52 of the second flange element 50 and the latter is translated relative to the second flange element 50 until the fir-tooth reliefs 76 and 77 are respectively received in the housings 58 and 59. At the end of this step, the clamping ring 71 exerts a radial clamping force on the wall 82 against the radially external surface 51.2 of the first section 51.

[0107] According to a third step, the distal end 52 of the second flange element 50, equipped with the clamping ring 71, is engaged through the end 49 of the first flange element 40. The second element 50 is then slid relative to the first element 40 along the axis Ax until the first assembly flange 46 comes into contact with the second assembly flange 54.

[0108] The assembly collar 60 is then mounted and tightened on the first assembly flange 46 and the second assembly flange 54.

[0109] Of course, the invention is not limited to the embodiments described but encompasses any variant falling within the scope of the invention as defined by the claims.

[0110] In particular, - although here the tubular body is in the form of a right cylinder, the invention also applies to other types of tubular bodies, such as for example a truncated cone-shaped, elliptical or any other shaped tubular body; - although here the first assembly flange comprises a groove for receiving a sealing gasket, the invention also applies to other sealed connection configurations such as for example a second assembly flange comprising a groove for receiving a sealing gasket, an absence of gasket, an absence of groove, or sealing made with jointing paste; - although here the clamping ring is attached by gluing to the tubular body, the invention also applies to a clamping ring which would be in continuity of material with the tubular body, such as for example a ring molded at the same time as the tubular body or attached to it by core welding; although here the clamping ring is attached by gluing to the tubular body, the invention also applies to other means for rigidly connecting the ring and the tubular body, such as for example shrink fitting, screwing, fillet welding or mounting in a groove; although here the seal is an O-ring, the invention also applies to other seal profiles such as a flat seal or a seal of any shape; although here the wall extends entirely in the transfer path, the invention also applies to a wall which would extend partially to the discharge end, such as for example a wall whose free edge describes a biased orifice whose upper apex would be connected to the supply end and a lower apex would be connected to the discharge end; although here a free edge extends facing a radially external surface of the transfer path, the invention also applies to other configurations in which the wall extends facing a radially external surface of the transfer path, such as for example an edge added by welding to a radially external surface of the transfer path, or a fold of the wall 82 arranged so that the free edge of the wall extends facing a radially internal surface of the transfer path.
