Definitions

  • the present invention relates to a cap for a container with a neck, intended to block a stopper in the neck of said container.
  • the invention relates in particular to a locking cap suitable for bottles, for example for pharmaceutical products capable of undergoing a freeze-drying step, before the cap is locked by the cap.
  • EP2464577 which describes a locking cap according to the preamble of claim 1, and EP2464580 , locking caps for necked containers.
  • These caps comprise an outer ring and a muselet formed of two rings interconnected by several substantially identical branches extending in an axial direction.
  • Such a cap makes it possible to block a stopper in the neck of the container, said stopper being held in the muzzle.
  • the stopper further comprises an opening in its foot which allows water vapor to escape during freeze-drying.
  • the document WO2012/069538 proposes a stopper device configured to surround an upper part of the stopper: during freeze-drying, the stopper, which has an opening in its base, is only partially pressed into the neck of the container, and the stopper device does not reach said collar.
  • the evaporative flows can pass from the opening of the plug to the outside, without disturbance.
  • This solution nevertheless has the disadvantage of holding the stopper in the neck insecurely during freeze-drying, because only a small part of the foot is held in the neck, whereas a very substantial part of the stopper carrying the stopper device n is not maintained.
  • the plugging device is only placed on the plug, and not held on the latter: the plugging device and the plug are therefore likely to come apart accidentally.
  • the present invention proposes a solution aimed at remedying all or part of the drawbacks of the state of the art.
  • the invention relates to a locking cap allowing effective freeze-drying while ensuring good hold of the stopper, in an intermediate holding position, prior to moving into the locking position.
  • the present invention relates to a locking cap 100 for a container 200 with a neck, intended to block a stopper 10 in the neck 201 of said container 200.
  • the container 200 can in particular take the form of a bottle, having a neck 201 of circular opening, ending in a flange 202 flared relative to the outer perimeter of the neck 201.
  • the outer diameter of the collar 202 is greater than the outer diameter of the neck 201, as illustrated in Figures la, lb.
  • the stopper 10 has a circular section and a T-shape with a head 11 and a foot 12, the head 11 being of greater diameter than the foot 12. Thus, when the foot 12 of the stopper 10 is completely inserted into the neck 201, the head 11 locks against collar 202.
  • the stopper 10 when the contents of the bottle are intended to be freeze-dried, the stopper 10 has an opening 13 in its foot 12, to allow the passage of evaporative flows as long as the stopper 10 is not completely inserted into the neck 202 ( figure 1b and 4b ).
  • the cap 100 when it is associated with the stopper 10, is capable of adopting two positions on the container 200: a first position, called intermediate holding position, in which the stopper 10 is partially pressed into the neck 201 ( figures 1a, 1b , 1c, 1d ). It is in this position that the container 200 can be subjected to a freeze-drying step, because the partial depression of the stopper allows the evaporative flows to pass through the opening 13 arranged in the foot 12 of the stopper 10. We will describe more far from the characteristics of the cap 100 which allow the effective circulation of these evaporative flows.
  • the cap 100 associated with the cap 10 can also adopt a second position, called locking, in which the cap 10 is fully depressed and locked in the neck 201 by the cap 100 ( figure 4a , 4b , 4c , 4d ). In this position, the stopper 10 hermetically closes the container 200, the foot 12 (and therefore the opening 13) being completely surrounded by the neck 201 of the container 200.
  • the cap 100 comprises an outer body 30 and a cage 20 configured to fit and lock axially in the outer body 30.
  • the cage 20 comprises an upper ring 21 and a plurality n of branches 22 connected to the upper ring 21 and defining therewith a generally cylindrical shape of the cage 20, of central axis z ( figures 2a, 2b ).
  • Cage 20 also comprises n/2 middle bridges 25 and n/2 lower bridges 26, each connecting two adjacent branches 22 together.
  • the adjectives “upper”, “median” and “lower” are used in reference to a cage 20 mounted in a cap 100 in the intermediate holding position or in the locking position on a container 200.
  • the container 200 being in the vertical position , the upper ring 21 of the cage 20 is in a “high” position, at a higher altitude than the other elements of the cage 20; the middle bridges 25 and the lower bridges 26 are respectively at a middle and low altitude.
  • the middle bridges 25 are located, in an axial direction z, between the upper ring 21 and the lower bridges 26.
  • the middle bridges 25 and the lower bridges 26 are arranged alternately around the periphery of the cage 20.
  • the cage has six branches 22, three middle bridges 25 and three lower bridges 26.
  • the middle bridges 25 occupy between 20% and 40% of the perimeter of the cage 20, for example 30%; and the lower decks 26 occupy between 40% and 70% of said perimeter, for example 60%.
  • the residual perimeter to reach 100% is occupied by branches 22 ( figure 2a ).
  • the cage 20 further comprises a plurality of first tongues 23, each being supported by a central bridge 25.
  • Each first tongue 23 is flexible and inclined with respect to the branches 22 towards the inside of the cage 20, at an angle between 20° and 60°, advantageously around 45°, towards the upper ring 21.
  • first tongues 23 are intended to block the stopper 10 inside the cage 20, against the upper ring 21, when the stopper 10 is associated with the cap 100.
  • the first tongues 23 flex to allow the head 11 of the stopper 10 when the latter is introduced into the cage 20, and come to block under the head 11, to prevent the stopper 10 from coming out of the said cage 20.
  • the cap 10 remains firmly attached to the cap 100 and no accidental separation between cap 10 and cap 100 can take place, in particular, when the cap 100 is in its intermediate holding position on the container. 200.
  • the cage 20 also comprises a plurality of second tongues 24, each supported by a lower bridge 26.
  • Each second tongue 24 is flexible and inclined with respect to the branches 22 towards the inside of the cage 20, at an angle between 20° and 60°, advantageously around 30°, towards the upper ring 21.
  • These second tabs 24 are intended to remain above the collar 202, slightly raised or in contact thereon, when the cap 100 is in the intermediate holding position ( picture 1a ). In this intermediate holding position, the lower bridges 26 and the branches 22 are intended to at least partially surround the collar 202. of freeze-drying.
  • each median bridge 25 is designed to provide an open space 251 between it and the flange 202, when the cap 100 is in its intermediate holding position ( figure 1c ).
  • the cage 20 thus has n/2 open spaces 251 distributed around its periphery, allowing efficient evacuation of the evaporative flows during freeze-drying steps.
  • each open space 251 has a height, along the axial direction z, of between 0.2 mm and 2 mm, and a width, along the perimeter of the cage 20, substantially equal to the width of a median bridge 25.
  • the height of the open space 251 can be defined as the distance, in the axial direction z, between the median bridge 25 and a line marking the start of the inward inclination of the cage 20, of the second tabs 24 ( figure 2a ). Indeed, it is at this inclination start line that the contact between the collar 202 and the second tabs 24 is likely to be established, thus defining the intermediate holding position.
  • the second tabs 24 are intended to bear under the flange 202 of the neck 201 of the container 200, when the cap 100 is in the locking position ( figure 4a , 4c ). Indeed, when passing into the locked position, the stopper 10 / cap 100 assembly will descend into / around the neck 201 of the container 200, so as to completely push the foot 12 of the stopper 10 into the neck 201, until that its head 11 rests on the collar 202. During the depression, the second tongues 24 flex and disappear to let the collar 202 pass, and come to block under the latter, thus locking the stopper 10 on the container 200.
  • the first tabs 23 are erased because they are in contact with the peripheral edge of the collar 202. They therefore do not remain under the head 11 of the stopper 10 and allow it to rest on the flange 202.
  • the middle bridges 25 then surround the peripheral edge of the flange 202, eliminating the open space 251.
  • the second tabs 24 are configured to allow passage from the intermediate holding position to the locking position of the cap 100 associated with the cap 10, when a weak force of between 30 N and 70 N, preferentially between 30 N and 50 N , is applied to the cap 100.
  • the second tongues 24 have an inclination with respect to the branches 22 of the order of 20° to 60°, a thickness between 0.6 and 1.3 mm and a flexibility conferred by the choice of the material forming the cage 20.
  • This advantageous configuration thanks to which the passage into the locking position is made possible by applying a force of low amplitude, makes it possible to collectively lock a plurality of caps 100 on their respective containers 200, by means of a plate exerting a force in the upper part of the plurality of caps 100.
  • This low closing force also makes it possible to compensate for the significant variations in height of the containers 200 and thus to achieve closure of all of said containers present under the closure plate without generating broken.
  • the outer body 30 is in a generally cylindrical shape with a central axis z ( 1d figures , 3a , 3b , 4d ).
  • One end 30a of outer body 30 is semi-closed and the other end 30b is open.
  • the open end 30b is provided to accommodate the cage 20, which will fit into the outer body 30, placing the upper ring 21 against the inner surface of the semi-closed end 30a.
  • the outer body 30 is configured to completely surround the cage 20 when the latter is nested, so as to prevent any access to said cage 20 from the outside, when the cap 100 locks the stopper 10 on the container 200.
  • the outer body 30 comprises a circular groove 31, provided in its cylindrical inner walls and capable of cooperating with complementary means of the cage 20, to lock the cage 20 axially in the outer body 30 ( picture 3a ).
  • These means are, for example, notches 221 arranged on the branches 22 of the cage 20 (visible on the figures 2a and 2b ) and provided to come to lock in the groove 31, when the cage 20 is completely inserted into the outer body 30.
  • the outer body 30 can thus rotate freely around the central axis z, when the cap 100 is in the locking position on the container, without damaging the cage 20 and risking affecting the reliability and sealing of the closure of the container 200.
  • the semi-closed end 30a of the outer body 30 is closed off by a cap 32, the role of which is to prevent any access to the stopper 10 ( 3c, 3d figures ).
  • the capsule 32 When it is desired to access the contents of the container 200, the capsule 32 must be removed, thus revealing the orifice of the semi-closed end 30a and of the upper ring 21 of the cage 20: the head 11 of the stopper 10 is accessible and the contents of the container 200 can be removed, for example, by inserting a needle through the stopper 10.
  • the capsule 32 once removed, cannot be reattached to the outer body 30, so as to ensure single use of the container 200 and its contents.
  • the irreversible fixing methods of the capsule 32 on the body 30 known from the documents EP2464577 and EP2464580 may be implemented within the scope of the present invention.
  • cap 10 can be introduced into the cap 100 after assembly of the cage 20, the outer body 30 and the capsule 32 forming the cap 100, it is possible advantageously to store the locking cap 100 and the cap separately. before use.
  • the locking cap 100 is completely removable and allows the removal of the stopper 10 for a total opening of the container ( figures 5a to 5e ).
  • the cage 20 comprises at least one lower bridge 26 supporting a third tongue 27 inclined towards the outside of the cage 20, in the direction of the upper ring 21.
  • the (at least one) lower bridge 26 also has a breakable zone 28 adjacent to said third tab 27 ( figure 5a ) .
  • the outer body 30 also has a breakable part 35 ( Figures 5b, 5c ).
  • the breakable part 35 may for example consist of a portion of the semi-closed end 30a and of the cylindrical wall, said portion being delimited by a double groove at the level of which the thickness of the outer body 30 is reduced ( figure 5c ).
  • a capsule 32 as for example illustrated in the figures 5d and 5e , is fixed on the outer surface of the semi-closed end 30a of the outer body 30.
  • the capsule 32 may comprise a pin intended to pass through an orifice present for example in the center of the semi-closed end 30a of the outer body 30, and in particular in the portion of said end belonging to the breakable part 35.
  • the attachment between the cap 32 and the outer body 30 can be made by riveting.
  • the third tongue 27 is initially designed so that it is inclined towards the outside of the cage 20, in the direction of the upper ring 21; due to its elastic properties, it is capable of folding back parallel to the inner walls of the outer body 30, when the cage 20 is locked axially in the outer body 30.
  • the third tongue 27 advantageously regains its initial inclination, towards the outside of the cage 20, which facilitates its gripping by the user.
  • the opening tab 27 advantageously has an elongated shape, which facilitates gripping all the more.
  • the cage 20 can then be easily detached from the neck 201 of the container 200 leaving free access to the removal of the plug 10.
  • the various elements forming the cap 100 according to the present invention are preferably made by molding a plastic material, compatible both with lyophilization processes, with gamma sterilization processes, autoclave and ethylene oxide (ETO), and with the targeted fields of application.
  • the cage 20, the outer body 30 and the capsule 32 could be formed from materials such as polycarbonate (PC), polypropylene (PP) or polybutylene terephthalate (PBT).
