Definitions

  • the present invention relates to a device for sealing a fluid product reservoir, for example a bottle containing a pharmaceutical fluid product.
  • a preferred field of application of the present invention is that of stoppers which can be pierced using a needle to remove all or part of the fluid product contained in the reservoir.
  • a closure device of this type comprises a cap of relatively soft material, such as an elastomer, which is force-fitted into the neck of the tank.
  • a cap of relatively soft material such as an elastomer
  • the cap is pushed into its closed position, in which it seals the tank in a sealed manner, and a metal capsule is mounted, in particular crimped, around the cap to secure it to the neck of the tank.
  • the capsule if the capsule is not perforated to allow the cap to be pierced to remove the fluid contained in the reservoir, the capsule must be completely removed before use, which can be difficult. This also implies a risk of accidental removal of the cap, with the consequent risk of loss of the fluid contained in the reservoir.
  • a metal capsule generally made of aluminum
  • the use of a part metal is disadvantageous in terms of recycling and environmental friendliness.
  • the removable protective cover can usually be removed and replaced easily, so that it is impossible to know whether or not product has already been withdrawn from the tank.
  • the integrity of the fluid contained in the tank is also not guaranteed.
  • this type of shutter device does not allow for high-speed assembly, for example using a machine that can simultaneously assemble several dozen shutter devices.
  • the present invention aims to remedy the aforementioned drawbacks.
  • the present invention aims in particular to provide a sealing device which guarantees the integrity of the fluid contained in the tank until its use.
  • the present invention also aims to provide a sealing device which includes a tamper-proof first use indicator.
  • the present invention also aims to provide a sealing device which makes it possible to use a stopper provided with a coating on the face in contact with the fluid product.
  • the present invention also aims to provide a sealing device which is completely free of metal.
  • the present invention as disclosed in claim 1 also aims to provide a sealing device which can be assembled at high speeds, in particular in an assembly machine capable of assembling several tens, for example one hundred, devices simultaneously.
  • the present invention also aims to provide a sealing device which is simple and inexpensive to manufacture and assemble.
  • said axial barrel of said plug comprises on its outer surface at least one sealing bead which cooperates with the interior of said neck of said tank to guarantee the sealed sealing of said tank.
  • said radial plate of said plug has an external diameter greater than the external diameter of said axial barrel, and comprises at least one annular projection extending downwards which, in the sealing position, cooperates with said upper axial edge of said neck.
  • said annular projection is peripheral and is, during the assembly of said sealing device on said neck of said tank, crushed on said upper axial edge of said neck to achieve sealing with said tank.
  • said radial plate comprises a central tapping zone defined inside an axial ring.
  • the radially external edge of said axial ring is conical, widening upwards.
  • said radial flange of said fixing ring is positioned on said radial plate of said plug, said central opening receiving said axial ring and said tapping zone of said plug.
  • the radial edge of said central opening snaps onto said radially external conical edge of said axial ring.
  • said first means of fixing said fixing ring are snap-fastening means, comprising at least one radial profile extending radially inwards.
  • said first fixing means comprise a single radial profile which extends over the entire periphery of said cylindrical axial sleeve.
  • the internal diameter of said axial envelope of said cover is identical to or very slightly greater than the external diameter of said axial sleeve of said fixing ring, so that in the assembled state of the closure device, said axial envelope is positioned around said axial sleeve with little or no play between them.
  • said second means for fixing said cover comprise one or more projection(s) extending radially outwards.
  • said complementary fixing means of said blocking element comprise one or more profiles extending radially inwards, said profiles snapping onto said one or more projection(s) forming said second fixing means of said cover.
  • said axial wall of said locking element comprises, on its lower axial edge, an annular radial wall extending radially inwards, the radially internal edge of said annular radial wall having a diameter less than the external diameter of said cylindrical axial sleeve of said fixing ring, and less than the external diameter of said reservoir.
  • said device is free of metal.
  • the present invention also relates to an assembly comprising a fluid product reservoir comprising a neck and a closure device as described above, for fixing and holding a cap on said neck.
  • axial and radial refer to the longitudinal central axis of the device.
  • top, bottom, “upper” and “lower” refer to the upright position of the device as shown in the Figures 11 and 12 .
  • the reservoir 1 may in particular be in the form of a bottle.
  • the reservoir 1 contains a fluid product, in particular of the pharmaceutical type.
  • a closure device is fixed to the neck 2 of the tank 1.
  • This closure device comprises a cap 10, a fixing ring 20, a cover 30 and a blocking element 40.
  • the plug 10 intended to seal the tank 1 in a sealed manner is preferably made of elastically deformable material, such as for example rubber or any other suitable elastomeric material.
  • This plug 10 comprises a radial plate 11 and an approximately cylindrical axial barrel 12. In the sealing position, the axial barrel 12 penetrates inside said neck 2.
  • the cap 10 includes sealing means for achieving sealing with the tank.
  • the axial barrel 12 comprises on its external surface at least one peripheral sealing bead 13 which cooperates with the interior of the neck 2 of the tank 1 to guarantee the sealed sealing of the tank.
  • the radial plate 11 has an external diameter greater than the external diameter of the axial barrel 12, and comprises at its radially outer edge an annular projection 14 extending downwards.
  • this annular projection 14 will deform and provide a certain spring effect as well as dimensional compensation, to optimize the assembly and/or the sealing in the assembled state.
  • the annular projection 14 is peripheral and is, during the assembly of the closure device on the neck 2 of the tank 1, crushed on the upper axial edge 3 of said neck 2 to achieve sealing with the tank 1.
  • the sealing bead 13 is no longer obligatory, and could either be completely omitted, or replaced by several parts of beads separated from each other and distributed on the periphery of the axial barrel 12, without sealing function.
  • the radial plate 11 comprises a tapping zone 15 intended to be pierced by a suitable device, such as a syringe, to collect all or part of the fluid product contained in the reservoir 1.
  • This tapping zone 15 is preferably central and defined inside an axial ring 16, as visible in particular in the figure.
  • the radially external edge of said axial ring 16 is slightly conical, flaring upwards.
  • the internal surface of the cap 10 which comes into contact with the fluid product contained in the reservoir 1 may be covered with a coating, in particular a thin film of ETFE (ethylene tetrafluoroethylene), in order to limit the interactions between the cap 10 and the fluid product.
  • a coating in particular a thin film of ETFE (ethylene tetrafluoroethylene), in order to limit the interactions between the cap 10 and the fluid product.
  • ETFE ethylene tetrafluoroethylene
  • the fixing ring 20 is provided for fixing and holding the cap 10 on the neck 2 of the tank 1.
  • This fixing ring 20 comprises a cylindrical axial sleeve 21 provided on the upper side with a radial flange 22 extending radially inwards and comprising a central opening 23.
  • said radial flange 22 is positioned on the radial plate 11 of the plug 10, with the opening 23 receiving the axial ring 16 and the tapping zone 15 of the plug 10.
  • the radial edge of said central opening 23 snaps onto the radially external edge of said axial ring 16 when the latter is slightly conical.
  • the cylindrical axial sleeve 21 comprises first fixing means 25, in particular by snap-fastening, for fixing to the neck 2 of the tank 1.
  • first fixing means 25 comprise a radial profile extending radially inwards. In the example shown, this radial profile is peripheral, but it could alternatively comprise several lugs distributed around the periphery. Other means of fixing to the neck 2 of the tank 1 are also conceivable.
  • the cover 30 comprises a radial disc 31 which, in the assembled state, is positioned on the upper surface of the radial flange 22 of the fixing ring 20, as visible in particular on the Figures 1 and 2 .
  • the cover 30 also comprises a cylindrical axial envelope 32 extending axially downward from said radial disk 31, the internal diameter of said axial envelope 32 being identical to or very slightly greater than the external diameter of the axial sleeve 21 of the fixing ring 20.
  • said axial envelope 32 is positioned around the axial sleeve 21 with little or no play between them.
  • the axial envelope 32 only extends over a small part of the height of the axial sleeve 21.
  • the axial envelope 32 comprises second fixing means 33, such as one or more projections extending radially outwards, which will be described in more detail below. These second fixing means 33 are advantageously provided at the level of the lower axial edge of the axial envelope 32.
  • the lower surface of the radial disk 31 comprises a central recess 35 delimited by an annular axial projection 36, said central recess 35 being found in the assembled state above the tapping zone 15 of the plug 10.
  • the annular axial projection 36 is connected to the axial envelope 32 by a plurality of radial bridges 37 distributed around the periphery. In this implementation, it is therefore the annular axial projection 36 and the radial bridges 37 which are, in the assembled state, in contact with the upper surface of the radial flange 22 of the fixing ring 20.
  • the locking element 40 comprises a cylindrical axial wall 41 whose internal diameter is greater than the external diameter of the axial casing 32 and that of the second fixing means 33 of the cover 30.
  • the axial wall 41 comprises complementary fixing means 43, advantageously at its upper axial edge.
  • these complementary fixing means comprise one or more profiles 43 extending radially inwards, with the internal diameter of said profiles 43 which is identical to or slightly greater than the external diameter of the axial casing 32 but less than the external diameter of the projections 33 of the cover 30.
  • the profiles 43 of the locking element 40 snap onto the projection(s) 33 of the cover 30.
  • the external shape of the profiles 43 and projections 33 can be produced in a conventional manner, with inclined planes sliding on each other during the assembly phase, and radial surfaces forming snap-fastening stops after assembly.
  • the cover 30 comprises several separate projections 33, for example two or three, distributed over the periphery, but a single projection 33 extending radially outwards over the entire periphery would also be conceivable.
  • the blocking element 40 comprises a single profile 43 extending radially inwards around the entire periphery, but several separate profiles 43 distributed around the periphery would also be conceivable.
  • the second fastening means 33 of the cover 30 and the complementary fastening means 43 of the blocking element 40 could be made differently, without necessarily forming a snap-fastening.
  • the cover 30 and the blocking element 40 then form a unitary subassembly.
  • Other alternative fastenings are also possible.
  • the axial wall 41 comprises on a portion of its periphery a tearable tab 42 defined between two grooves 44, 45 which form bridges of thin material.
  • This tab 42 comprises a gripping portion 46 which the user can grasp to tear the tab on a portion of the periphery of the locking element 40.
  • the tearable tab 42 ends on the side opposite the gripping part 46 by a flared part 42', so that at the end of tearing, the axial wall 41 opens over its entire height, thus allowing the blocking element 40 to be removed from the sealing device.
  • said axial wall 41 On its lower axial edge, said axial wall 41 comprises an annular radial wall 49 extending radially inwards.
  • the radially inner edge of said annular radial wall 49 has a diameter smaller than the outer diameter of the cylindrical axial sleeve 21 of the fixing ring 20.
  • this annular radial wall 49 In the assembled state, this annular radial wall 49 is positioned axially under said cylindrical axial sleeve 21, thus preventing removal of the locking element 40 by upward axial traction.
  • the radially inner edge of the annular radial wall 49 also has a diameter smaller than the outer diameter of the tank 1.
  • the cap 10 In the assembled state of the closure device, the cap 10 seals with the neck 2 of the tank 1, the fixing ring 20 fixes and maintains said cap 10 in its sealed closure position, the cover 30 protects the cap 10 and prevents access to its tapping zone 15, and the element of locking device 40 prevents the removal of the cover 30 while being held in the locking position on the one hand by the snap-fastening with the cover 30 and on the other hand by the axial locking provided by the fixing ring 20 at the annular radial wall 49.
  • the shutter device In the assembled state, the shutter device therefore forms a non-dismountable subassembly.
  • the fixing ring 20 is first assembled on the plug 10, advantageously with a snap-fastening of one on the other at the central opening 23. Then, in the example of the figure 10 , the cover 30 is assembled on the fixing ring 20 from above, and then the locking element 40 snaps into place from below on the cover 30, according to the arrow F1.
  • the cap-fixing ring unit can first be arranged in the locking element 40, and then the cover 30 can be snapped into place from above.
  • the assembly of the cover 30 and the locking element 40 around the cap-fixing ring unit can be done in a single step, the cap-fixing ring unit then being sandwiched between the cover 30 and the locking element 40.
  • the assembly of the closure device on the neck 2 of the tank 1 is advantageously done by axially pushing the closure device downwards, according to the arrow F2 on the figure 11 .
  • the presence of the central recess 35 in the cover 30 ensures that during assembly, the entire force F2 exerted on the cover 30 is transmitted to the fixing ring 20, without direct interaction between the cover 30 and the plug 10.
  • said at least one sealing bead 13 are chosen such that the sealing is guaranteed in the assembled state, without generating excessive forces during assembly. This makes it possible to use an assembly machine with baskets or nests capable of simultaneously assembling several dozen devices, for example a hundred.
  • the closure device After assembly of the closure device on the tank, the closure device includes a tamper-proof first-use indicator. Indeed, as long as the tear-off tab 42 is not torn, and the blocking element 40 removed, the cover 30 cannot be removed. The contents of the tank are therefore perfectly protected. After removal of the blocking element 40, the cover 30 can also be removed. On the other hand, it is then no longer possible to replace another blocking element 40, because this assembly must necessarily be done before assembly on the tank 1. Indeed, the internal diameter of the annular radial wall 49 being less than the external diameter of the tank 1, it is not possible to assemble a blocking element 40 over the tank 1. Similarly, the internal diameter of the annular radial wall 49 being less than the external diameter of the cylindrical axial sleeve 21 of the fixing ring 20, it is not possible to assemble a blocking element 40 over the fixing ring 20.
