Definitions

  • Ampoule for receiving a dose of a liquid agent to be taken into an application device, preferably an injection syringe, on the ampoule vessel of which an ampoule neck with a predetermined breaking point and handle for opening the, for example, conical head of the application device is provided.
  • an application device preferably an injection syringe
  • ampoules of this type have mostly been made of glass, with the ampoule neck being sealed at its free end after the ampoule has been filled in order to seal it tightly.
  • the user has to prearrange the wall of the ampoule neck at a suitable point with an ampoule saw and break off the sealed portion of the ampoule neck in order to insert a pull-on cannula into the opened one, which is placed on the head of an application device, for example the cone for the injection needle of an injection syringe Insert the neck of the ampoule and transfer the contents of the ampoule to the application device, for example to be able to pull it into the injection syringe.
  • an application device for example the cone for the injection needle of an injection syringe
  • Glass ampoules are also already known in which a predetermined breaking point is pre-formed by scratching the wall of the ampoule neck and secured by a marking strip.
  • a predetermined breaking point is formed on the ampoule neck in that an annular wall area of the ampoule neck is provided with internal stresses in the glass by means of special heat treatment.
  • the scoring by the user is not necessary. It is only necessary to break off the part of the ampoule neck which is closed by melting, this part of the ampoule neck serving as a handle.
  • the phenomenon occurs that when a part of the ampoule neck breaks off, glass particles enter the Get ampoule content.
  • the syringe cylinder with a receiving cone for a cannula is made of a plastic ampoule and is closed at the end opposite the ampoule neck to the plunger of the syringe .
  • the ampoule neck has a predetermined breaking point in order to break off the closed part at a defined point and to be able to use the remaining part as a receiving cone for the cannula.
  • Dose containers made of plastic are also known, for example from US Pat. No. 4,643,309, the container neck of which is conical in order to be able to insert the conical head of an injection syringe after removal of a closure cap.
  • the container neck of which is conical in order to be able to insert the conical head of an injection syringe after removal of a closure cap.
  • there are no facilities for admitting air so that when the contents of the container are transferred to the injection syringe, either the seat of the head in the container neck must be loosened or the container wall must be pressed together. Both make it difficult to transfer the contents of the container and make the activity of the user unsafe during the transfer.
  • ampoules which are used to hold liquid agents to be taken up in application devices, for example injection syringes, in such a way that the transfer of the ampoule content into the application device, for example the drawing up of the ampoule content onto an injection syringe, is made considerably easier and safer becomes.
  • the ampoule neck is made of elastically stretchable material, and is designed as an insertion and holding ring for the preferably conical head of the application device designed to attach the actual applicator (injection needle) and that a ventilation device leading into the interior of the ampoule is provided.
  • the ampoule with its ampoule neck can be securely and sufficiently firmly taken over for the ampoule contents and - apart from the air inlet - can be plugged together tightly with the respective application device.
  • the user no longer has to hold the ampoule during the transfer of the ampoule contents into the application device, but can instead safely insert the application device into the open ampoule neck. and hold the application device, for example an injection syringe, with one hand and actuate it with the other hand to open the contents of the ampoule.
  • the elastically stretchable design of the ampoule neck does not represent a significant increase in effort, particularly not if the entire ampoule is made in one piece from elastically stretchable material, for example plastic such as polypropylene.
  • the ampoule neck carries at its free end a closure piece which is connected in one piece to the mouth edge region of the impulse neck via an annular predetermined breaking point, the actual mouth edge of the ampoule neck being designed as a funnel-shaped introduction for the head or cone of the application device.
  • the actual mouth edge of the neck of the ampoule can preferably be designed with a rounded curvature to form the funnel-shaped introduction.
  • the closure piece can have a substantially disc-shaped part arranged within the mouth edge region, the predetermined breaking point surrounding the closure piece being arranged so as to be recessed around the funnel-shaped insertion relative to the actual mouth edge of the ampoule neck.
  • the head of the application device for example the receiving cone of an injection syringe
  • the head of the application device can be inserted particularly safely and simply into the mouth edge region of the ampoule neck after the closure piece has been removed.
  • the residues of the predetermined breaking point remaining when the closure piece is removed reach the outer surface of the head or the receiving cone and are thereby pressed against the peripheral wall of the ampoule neck, so that the detachment of plastic particles from these residues the predetermined breaking point is impossible or made harmless for the transfer of the ampoule content into the application device because particles adhering to the remnants of the predetermined breaking point are displaced radially outward from the peripheral surface of the head or receiving cone and are prevented from penetrating into the interior of the ampoule.
  • a ventilation device on the ampoule which is closed during transport of the ampoule and is closed when the ampoule is in use and which can be opened simultaneously with the ampoule neck when the ampoule is in use, ensures that when the liquid ampoule contents are sucked in by the application device, for example an injection syringe, air flows into the ampoule container. This avoids the formation of a vacuum inside the ampoule container, which would resist the aspiration of the liquid ampoule contents by the application device.
  • the ampoule neck can have a ventilation channel on its inside, which can extend essentially axially to the ampoule neck. However, it is preferred to provide a separate ventilation opening in addition to the ampoule neck to form the ventilation device.
  • this ventilation opening can be formed on a ventilation tube which extends parallel to the ampoule neck and which has a closure element which can be broken off together with the closure piece of the ampoule neck.
  • the ampoule tube can be made longer than the ampoule neck after the interior of the ampoule.
  • the separate ventilation opening to be provided next to the ampoule neck can also be a thinned, penetrable wall area of the ampoule shoulder. It is also possible to separate and form a ventilation tube into the ampoule shoulder or another wall part of the ampoule at a distance from the ampoule neck.
  • the ampoule according to the invention is preferably intended for use in conjunction with conventional injection syringes which are designed for multiple use for drawing in the liquid to be administered and with a receiving cone for applying an injection needle.
  • the ampoule neck is preferably designed with a greater axial length than the receiving cone of conventional injection syringes. This ensures that the receiving cone of an injection syringe pressed into the mouth of the ampoule neck is positively surrounded by the ampoule neck. It is achieved in this way that the entire amount of liquid contained in the ampoule can be sucked into the injection syringe.
  • the ampoule container together with the ampoule neck, is formed in one piece from thermoplastic material, preferably polypropylene, and is sealed at its end opposite the ampoule neck after filling.
  • the ampoule can be designed similarly to a dose container known from DE-PS 26 53 993 or 19 65 761.
  • the ampoule vessel can be particularly advantageously thicker on its part adjacent to the ampoule neck than on its part opposite the ampoule neck.
  • the ampoule container on its part adjacent to the ampoule neck is designed to be significantly less flexible than on the part opposite the ampoule neck. This has the advantage that when the ampoule is touched on the part adjacent to the ampoule neck, undesired compression and thus inadvertent pressing out of ampoule contents avoided and the ampoule can still be firmly gripped.
  • the container wall is sufficiently thin and flexible that it can be compressed and welded after the ampoule has been filled.
  • the ampoule container with a cylindrical outer shape and the open end opposite the ampoule neck can be produced in one piece with the ampoule neck and its closure piece by hand by injection molding.
  • the cylindrical outer shape of the wall of the ampoule container has the advantage on the one hand that any further processing, in particular printing, and the feeding within the filling and welding machine is made considerably easier.
  • the cylindrical outer shape has the advantage that the expansion of shape at the weld, which is unavoidable during welding, is noticeably less than that of ampoules, in which the conical shape of the ampoule container is assumed.
  • the production of ampoules according to the invention with a cylindrical outer shape of the ampoule container by injection molding may initially appear difficult.
  • the ampoule container can be made with a slightly conically tapering interior from the open end to the ampoule neck and correspondingly with a wall thickness increasing conically from the open end to the ampoule neck.
  • the demolding of the ampoule according to the invention during manufacture by injection molding is considerably facilitated and, on the other hand, a desired wall formation of the ampoule vessel is achieved with less flexibility in the part adjacent to the ampoule neck and greater flexibility in the part remote from the ampoule neck.
  • the transition from the ampoule container to the ampoule neck can also be designed as an ampoule shoulder in which blind embossments are provided, for example for information about the volume and content of the respective ampoule.
  • This blind embossing on the ampoule shoulder inevitably falls into the user's field of vision when touching the ampoule to open it and when attaching the ampoule to an application device, so that additional security can be given that an ampoule before opening and before applying the application device to the correct content and correct amount is checked.
  • the empty ampoule can also be kept as a control piece.
  • the ampoule 10 is made in one piece from thermoplastic, namely polypropylene by injection molding. It has an ampoule container 11 which merges into an ampoule neck 13 via an ampoule shoulder 12. At the free end of the ampoule neck 13, a closure piece 14 is formed, which can be removed by twisting it off at the same time as breaking off and tearing it off. At the end remote from the ampoule neck 13, the peripheral wall of the ampoule container 11 is compressed flat after filling and welded tightly at a closure seam 15.
  • the ampoule neck 13 is elastically stretchable due to the production of the entire ampoule 10 from polypropylene and as an insertion and retaining ring for the head of one Application device, for example the receiving cone 17, an injection syringe 16, wherein this conical head or receiving cone 17 is used to attach the actual applicator, for example a conventional injection needle.

  • the disc-shaped part 18 of the closure piece 14 is arranged in the interior of the mouth edge region 20 of the container neck 13 and is connected in one piece to the mouth edge region 20 of the ampoule neck 13 via an annular predetermined breaking point 21 surrounding the periphery of the disc-shaped part 18.
  • the container neck 13 is sealed at its free end by the disk-shaped part 18 of the closure piece 14 and the predetermined breaking point 21.
  • the predetermined breaking point 21 is destroyed by unscrewing, breaking off and tearing off the closure piece 13.
  • the mouth of the ampoule neck 13 is exposed.
  • the head of an application device for example the receiving cone 17 of an injection syringe, 16 can now be inserted into the open end of the ampoule neck 13.
  • the rim area 20 of the ampoule neck is essentially funnel-shaped towards the inside.
  • the different embodiments shown in the drawing show variations in the design of this funnel-shaped introduction. In the example in FIG.
