Definitions

  • the present invention relates to a closing system for a hand-held medical container, said closing system allowing both opening and closing of said container with a single hand
  • Small containers that can be hold with a single hand, such as bottles, vials or tubes are widely use in everyday life to store some material in the form of a liquid, a paste or divided matter. They usually consist in a storage compartment, intended to store the material and a closing system, intended to prevent spilling of the material when the container is transported or turned over.
  • the distal end of a component or apparatus must be understood as meaning the end furthest from the hand of the user and the proximal end must be understood as meaning the end closest to the hand of the user, with reference to the injection device intended to be used with said component or apparatus.
  • the distal direction must be understood as the direction of injection with reference to the injection device, and the proximal direction is the opposite direction, i.e. the direction of the transfer of the product from the vial to the injection device.
  • hand-held containers such as vials are commonly used to store and distribute drugs or vaccines intended to be injected to patients.
  • Such containers are inexpensive, durable and can be made sterile before being filled with a pharmaceutical product.
  • a number of doses can be stored in a limited space and such medical containers are therefore convenient for medical staff working outside of the hospital. Indeed, they are widely used in large scale immunization programs or during pandemics, where populations living in remote area, far away from towns and hospital facilities, need to be vaccinated or cured.
  • vials are usually closed by a septum intended to be pierced by the needle of an injection device.
  • This septum therefore acts as a barrier between the inside of the vial and the outside environment: it protects the pharmaceutical product stored in said vial from outside contaminants such as dust, bacteria, germs or viruses.
  • the septum itself may be damaged during transportation or when handled in rough conditions. This could include shocks, excessive sunlight, excessive temperature, very low or high humidity level, or contact with hazardous liquid. Additionally, it is sometimes difficult to guaranty favorable hygienic conditions in such remote locations, and the septum and/or the vials could be contacted by unclean hands or contaminated surfaces. Finally, and in the case of multidose vials, the septum needs to be pierced several successive times i.e. as many times as the number of product doses stored into the vial. This repeated piercing could mechanically damage the septum, for example by leaving tiny holes through its material.
  • a first embodiment of the present invention is a closing system for a container to be hold with a single hand, said closing system comprising:
  • the closing system of the present invention is intended to be adapted to a hand-held container.
  • This could be a medical container, such as for example a conventional vial for storing pharmaceutical products, such as multidose vials for vaccines.
  • a vial 1 is shown on Figures 1A-1C and generally comprises a tubular barrel 2 having a longitudinal axis A, closed at an end and having a collar 3 at the opposite end, said collar 3 forming an opening 3a closed by a septum 4.
  • the septum 4 is fixedly attached to the collar 3 of the vial 1 by a peripheral band 5, said peripheral band 5 leaving a part of the septum 4, herein called outer surface 4a of the septum, directly facing the outside of the vial 1, namely the outside environment.
  • the septum 4 is usually made of a material impermeable to gas and liquid and it seals hermetically the content of the vial 1.
  • the septum 4 is also pierceable by the needle of an injection device intended to be filled with the product contained in the vial, said septum 4 being accessible to said needle via its outer surface 4a.
  • the closing system of the present invention could be integrated in the hand-held container, the cap being a part of the container wall.
  • the closing system of the present invention allows an efficient closure of the vial and an efficient protection of the vial septum. Thanks to the hinge and the guiding member, it is also very simple to manipulate with a single hand: the container can be grasped by one hand and only the thumb is required to open and close the cover.
  • the closing system is thus particularly valuable in the field of medicine where the health workers often need their second hand to handle a swab, another container or an injection device. Furthermore, the cover cannot be separated from the cap even if the container falls during operation. The closing system is therefore resistant to rough conditions often met in remote areas, outside the hospital.
  • the hinge of the closing system comprises a shaft extending in the distal direction from the cover, and a corner hole provided in the transversal wall. This hinge allows a straightforward planar movement of the cover regarding the cap: the cover slides in a planar rotation regarding the transversal wall to give access to the access port. Moreover, the cover can be guided during the whole movement by a single finger contacting the guiding member.
  • the guiding member is a stud. This shape has been found preferable to allow the user's thumb to guide the cover during the closing and the opening. Moreover, the stud also provides a visual and tactile indication to the user for an obvious operation of the closing system. Any health care worker is thus able to use the closing system in an appropriate way without a specific training.
  • the guiding member could be a hole, a lug or a ring.
  • the cover further comprises a pushing surface, to allow the opening of the cover by a suggested thrust movement from the user's thumb. It also provides further visual and tactile indication for an untrained user to operate the closing system in an appropriate way.
  • the hinge is located on a side of the cover. This position allows a fast opening with only a limited movement of the user's thumb.
  • the hinge is also located on a rear portion of the cover, to allow a natural sliding movement to the back of the closing system.
  • the pushing surface is located on a front portion of the cover, in order to be located nearby the user's thumb when the user grasps the container with his hand. Due to its position, the user is lead to push onto this surface without a specific training.
  • the stud is located on a rear portion of the cover. This position is advantageous to supplement the pushing surface during the opening movement, in particular in case the user does not grasp the container in the most appropriate way.
  • the stud is located on a first side of the cover and the hinge is located on an opposite, second side of the cover. Consequently, the stud located on a rear portion of the cover is brought nearby the user's thumb when the cover is in the open position. The closing movement is thus rendered obvious to untrained users, as they only need to pull the stud with their thumb to close the cover.
  • the pushing surface and the stud are located on the same first side of the cover.
  • the pushing surface is thus located at another extremity of the cover regarding the hinge, which allows smooth and easy opening of the cover thanks to a leverage effect.
  • said thumb would come in contact with the stud and a fast opening will be possible anyway.
  • the closing system comprises unidirectional means only allowing a clockwise or a counterclockwise rotation. This forces the user to manipulate the closing system in only one direction, therefore restricting any inappropriate operation.
  • the closing and the opening must be done in the same clockwise or counterclockwise movement, which renders the closing system safe and obvious to manipulate.
  • said unidirectional means comprises a tooth located on a flexible leg substantially parallel to said cover, and three openings located on said transversal wall.
  • the closing system further comprises locking means to maintain the cover in a closed position during storage. These locking means prevent undesired opening of the cover, in particular during storage and shipping.
  • the locking means comprises a peg located on a longitudinal extension of said cover, and a notch located on the skirt. Only a small pressure is required to disengage the peg from the notch and these locking means efficiently prevents undesired opening without hampering a simple opening of the closing system.
  • said transversal wall comprises a rear extension intended to block the user's index finger when said user grasps said closing system. This helps the user to firmly grasp the container, even if the user's hand or the container is wet or dirty. Moreover, it also helps to correctly place the thumb nearby the pushing surface and thus improves the obviousness to manipulate the closing system.
  • the adaptor 10 comprises a gripping member 20 intended to secure the adaptor onto the vial 1, a counting ring 30 intended to provide information on the number of doses of product already withdrawn from the vial 1 and/or still left inside the vial 1, a cap 40, intended to be snap-fitted to the gripping member 20, a pierceable elastomeric piece 50 intended to be accommodated in the cap 40, and a cover 60 intended to prevent or allow access to the opening 3a of the vial 1, once the adaptor 10 is coupled to the vial 1.
  • the gripping member 20 comprises a U-shaped body 21, having a partially tubular wall 22 with a height suitable for surrounding the collar 3 of the vial 1 (see Figures 11A-11B ).
  • the gripping member further comprises two free ends 22a corresponding to the ends of the branches of the U, the U-shaped body 21 therefore forming a clipping member.

  • the counting ring 30 is provided with information data corresponding to these ten doses of product to be withdrawn from the vial 1.
  • the flat cylinder 31 is thus provided with printed digits 34 indicating the numbers 1 to 10, these digits being regularly distributed along the circumference of the flat cylinder 31.
  • the cap 40 comprises a transversal wall 41 having a substantially circular shape except a corner 41a, and a rear extension 41b.
  • a front rim 42 is extending from the front of the transversal wall 41 in the distal direction.
  • a U-shaped skirt 43 also extends from the transversal wall 41 in the distal direction, the free ends 43a of the U forming a front opening 43b of the skirt 43. Close to each free end 43a, the skirt 43 is provided on its outer surface with four recesses 43c (only two being visible on Figure 2 ) and a notch 43d immediately nearby the transversal wall 41.
  • the circular transversal wall 41 is provided with a central access port 44 and with a front side hole 45.
  • the transversal wall 41 is further provided in its corner 41a with a corner hole 46 surrounded by three openings 49a, 49b and 49c regularly placed around the corner hole.
  • the access port 44 is designed to accommodate a needle and is described as a needle access port 44.

  • the elastomeric piece 50 can be presented by the distal face of the cap 40, proximally pushed into the needle access port 44. It is easily deformed in the needle access port thanks to its elastomeric properties which allows the inner radial pegs 44c to pass along the distal portion of the longitudinal wall 54 up to the circular groove 56.
  • the shoulder 57 rests on the abutment surface 44d of the needle access port 44 and prevents any further proximal translation: the elastomeric piece 50 is correctly assembled with the cap 40.
  • the flat cylinder 31 of the counting ring is snap-fitted on the cap 40 and the central hole 33 is engaged with the radial outer pegs 47 of the cap 40, is blocked in the distal direction. Therefore, the flat cylinder 31 is capable of rotating with respect to said radial outer pegs 47.
  • the cap 40 is itself snap-fitted on the gripping member 20 thanks to the recesses 43c engaged with the radial pegs 23 present on the tubular wall 22 of U-shaped element 21 of the gripping member 20. As a consequence, the cap 40 is fixed with respect to the gripping member 20.

  • the shaft 66 can rotate within corner hole 46, in a clockwise direction indicated by the arrow 69.
  • the shaft 66 together with the corner transversal rim 48 therefore form a hinge at the corners 41a and 61d of the cap 40 and the cover 60, respectively.
  • This hinge (46, 66) allows the planar rotation of the cover 60 from a first position closing the needle access port 44 to a second position giving access to the needle access port 44.
  • this hinge is located on a side of the cover 60. More precisely, in the present embodiment, the hinge (46, 66) is located on the rear portion of the cover 60, i.e. on the corner 61d. The cover 60, the cap 40 and the hinge (46,66) therefore form a closing system for the vial 1.
  • the cover 60 is maintained in its first, close position as the peg 63a engages the notch 63d of the cap 40, the peg 63a and the notch 43d serving as locking means for preventing any undesired rotation of the cover 60.
  • the cover 60 therefore allows an efficient protection against dust and contamination of the elastomeric piece 50 and thus of the septum 4 of the vial 1, when the vial 1 is not in used.
  • the vials containing vaccines are stored at cold temperature (2-8°C) and, when a user takes a vial out of the refrigerated storage, some condensation could appear on the surface of the vial septum and/or on the surface of adaptor 10 as it is exposed to ambient temperature.
  • the discontinuous circular rim 64d of the cover 60 is in tight contact with the transversal wall 41 of the cap 40, in particular with the portion located around the needle access port 44, when the cover 60 is in close position. This prevents any condensation from being trapped into the recess 51 while effectively closing the needle access port 44 as this discontinuous circular rim 64d allows a gas exchange between the recess 51 and the outside environment.
  • distally slopped surface 52 of the elastomeric piece 50 shown on Figures 7A and 7B is also designed to guide the condensation towards the recess 51 therefore limiting the trapping of the condensation between the elastomeric piece 50 and the needle access port 44.
  • the growth of bacteria around the elastomeric piece 50 is therefore widely prevented, as this space is kept dry from condensation.
  • the condensation is not trapped but directed towards the recess 51 where it can be evaporated, even when the cover 60 is closed thanks to the discontinuous rim 64d.
  • the protrusion 55 of the recess 51 remains a dry and clean pierceable surface as the limited amount of condensation is restricted to a portion of the bottom surface around the protrusion 55.
  • the discontinuous circular rim 64d, the distally slopped surface 52 and the protrusion 55 are thus all designed in such a way to prevent or to limit contamination due to bacteria growing in condensation nearby the pierceable elastomeric piece 50 and the septum 4.
  • the distal tooth 64c of the cover 60 is engaged successively with the opening 49a, 49b, and 49c of the cap 40as this tooth 64c has a slopped surface inclined toward the direction of the rotation as seen on Figure 9B . Thanks to its straight surface in the counter direction of the rotation, the flexible leg 64b and the distal tooth 64c prevent the cover 60 from moving in the counterclockwise direction, and therefore form, together with the openings 49a, 49b and 49c unidirectional means. These unidirectional means help and guide the user to operate the adaptor 10 in a safe and appropriate manner, even if he does not have received any particular training.
  • the user sustains the pressure on the pushing surface 62 until the cover 60 is at 180° of its first position and allows the access to the needle access port 44.
  • the user can withdraw a dose of the pharmaceutical product stored in the vial 1.
  • This can be done by turning the vial over, the proximal face of the transversal wall 41 now substantially facing the ground as shown on Figure 12B .
  • the user then pierces both the elastomeric piece 50 and the septum 4 of the vial 1 with the needle 71 of an injection device 70. Thanks to the proximal surface 52 of the elastomeric piece 50, slopped distally towards the center of the recess 51, the needle 71 is guided into the recess 51 to pierce directly the central protrusion 55.
  • the risk of accidental pricking of the user by ripping of the needle on the needle access port is significantly reduced.
  • the needle 71 pierces the elastomeric piece 50 and the septum 4, it directly penetrates the dry and clean protrusion 55, and is not contaminated by any dust or bacteria developing in condensation water.
  • the user can then fill the injection device 70 by withdrawing a dose of the pharmaceutical product contained in the vial. Even if the inside of the vial 1 is under vacuum after removal of the needle 71, no outside air is sucked inside. Indeed the distal surface 53 of the elastomeric piece 50 and in particular the protruding part 53a engages the surface 4a of the septum 4. The interface between the elastomeric piece 50 and the septum 4 is preserved from outside air, condensation and contaminants; the elastomeric piece 50 and the septum 4 of the vial 1 behave has a single piece. The elastomeric piece 50 therefore allows the septum 4 of the vial to reseal before the complete removal of the needle 71 and prevent sucking of the outside air into the vial.
  • the elastomeric piece With the cover 60 in an open position, the elastomeric piece is directly exposed to outside contaminants. Nonetheless, any direct contact is avoided with the bottom surface of the elastomeric piece, intended to be pierced, even if the user's fingers or any contaminated surface might come in contact with the pierceable elastomeric piece 50.
  • the recess 51 and the proximal surface 52 prevent the user's finger or any other contaminated surface to contact the bottom surface 53.
  • any dust would penetrate the recess or if any condensation would form, they will mainly be restricted around the protrusion 55, therefore keeping the protrusion 55, intended to be pierced, substantially away from contaminants.
  • the recess 51 therefore provides an additional and valuable protection against the contamination of the inside of the vial 1. This is particularly important when the adaptor 10 is used in locations where the user has a limited access to efficient soap or sterilizing solution.
  • the adaptor 10 can be closed. Performing this step implies moving the cover 60 from the second open position back to its first close position.
  • the pushing surface 62 of the cover is now in the opposite direction as regards of the thumb of the user who has to pull on the stud 68 with his thumb for moving the cover 60 in a planar clockwise movement towards its close position. In this position, the peg 63a of the cover 60 is re-engaged in the notch 43d of the cap 40and the cover 60 is locked.
  • the pushing surface 62 and the stud 68 therefore permit a relay as an interface for the user's thumb.
  • the pushing surface 62 allows the user to rotate the cover 60 for the first 180° (the opening), while the stud 68 allows the user to rotate the cover 60 for the last 180° (the closing).
  • the pushing surface can also help the user for the very last degrees of the rotation, as it is almost came back to its first position in front of the thumb.
  • the stud 68 can also be used during the opening, for example if the user is unable to grasp the vial 1 in an appropriate way.
  • the clockwise rotation indicated by the arrow 69 present on the cap is forced by the unidirectional means 64b, 64c, 49a, 49b and 49c.
  • the fingers of user are just in contact with the cover 60 and with the rear extension 41b of the cap 40 and do not contact neither the cap 40 nor the elastomeric piece 50. This leads to a safe and straightforward operation with limited contamination, as the user is prevented from touching the pierceable elastomeric piece 50. The user is therefore preserved from any accidental pricking or movement and does not require particular training to properly operate the adaptor 10.
  • the closing system comprising the transversal wall 41, the cover 61 and the hinge (46, 66) could be used with any container intended to be manipulated with a single hand, particularly in the medical area but also in the fields of cosmetics, food or industry.
  • the system according to the present embodiment is included on an adaptor mounted on a container, but could be directly integrated on the container, therefore providing a container "ready-to-use" without the mounting step.
  • the closing system of the present invention allows a safe and straightforward manipulation even when operated by a untrained user.
