Definitions

  • the invention relates to a sealing element for containers with pharmaceutical content, in particular for bottle-shaped containers with substances intended for infusion, transfusion or injection, which consists of a support part with at least one cavity and a filling part made of elastic material, which fills the cavity and one which rests against the container neck Sealing surface forms.
  • a method for producing such a sealing element is also specified.
  • Stopper-shaped or disk-shaped elastic sealing elements for containers with pharmaceutical contents are known, for example, from DE-A-27 27 737 and from DE-C-23 27 553.
  • the bottle neck is sealed with the aid of a pierceable elastic sealing element which is overlaid by a closure cap which can be removed in the central region and / or as a whole.
  • the closure cap can, as shown in DE-B-23 61 350, be formed by a metal crimp cap, which is fixed with its crimp edge to the bottle neck and thereby holds the sealing element.
  • the stopper-shaped or disc-shaped sealing elements used for pre-closing the bottle-shaped containers are made of solid rubber or a plastic with corresponding rubber-elastic properties.
  • Such massive training means a considerable waste of material of the relatively expensive elastic rubber material.
  • rubber components penetrate into the container contents, mix with it and thereby contaminate it.
  • particles of the stopper detached from the needle tip are also introduced into the container contents and passed on with the container contents.
  • a pot-shaped support part forms one or more cavities which are filled with an elastic filling material. The filler does not penetrate the support part.
  • FR-A-1 325 077 describes a plug-shaped sealing element in two-component design. This consists of a plastic support part, which forms receiving spaces for introducing separate rubber-elastic filler parts and for an edge seal against the container neck.
  • the rubber-elastic filler parts which are inserted as form-fitting insert parts in corresponding cylindrical-shaped receiving spaces, cover molded membrane sections in the support part, which can be pierced together with the rubber-elastic filler parts when used with an injection needle.
  • the invention is based on the task of designing a sealing element of the type mentioned at the outset, which can be found in CH-A-397 953, in such a way that a filling part consisting of several parts can advantageously be connected to the supporting part in one operation.
  • This object is achieved in that the support part is designed as an open skeleton, in which the filler part is inserted in such a way that the filler part and the skeleton part penetrate, so that the filling of the cavity and the support layer with sealing surface form a coherent part.
  • the filling part produced by injection into the support part is firmly - preferably permanently - connected to it.
  • This firm connection of a relatively dimensionally stable skeleton with a penetrating, injected elastic filler sufficient dimensional stability and elasticity can be achieved with inexpensive use of materials.
  • the sealing element can be designed in various ways, expediently as a plug.
  • the support part has an upper cover part with a flange edge, which is connected to a cylindrical plug-in part via webs.
  • the support part has an upper cover part with a flange edge, which is connected to a solid cylindrical or hollow cylindrical plug-in part, with passage-side recesses being provided as penetration points between the support part and the filler part.
  • a membrane part superimposed with a support layer made of the coherent filling part can advantageously be integrally molded in the support part.
  • the elastic support layer which forms the filling part on the membrane part, holds infusion and injection needles in place thanks to their clamping action.
  • a stripping effect occurs on it, which results in the filling part ejected particles and the like are kept away from the container contents.
  • the filler part forms a support layer on a membrane part
  • Puncture orientation recesses for the circular and annular surface formed by the reinforcing strips on the membrane part are preformed on the surface of the support layer of the filling part on the membrane part. These orientation recesses enable the targeted insertion of the transfusion needle or an additional injection needle.
  • a further use advantage when pulling out the plug-shaped sealing element can optionally be achieved in that a pull-off element is integrally formed on the support part.
  • the pull-off element can expediently be designed in a ring shape, its height essentially corresponding to the thickness of the cover part enclosed by the ring-shaped pull-off element.
  • the pull-off ring forms the outer edge of the cover part and can be overlaid with it by a crimp cap when producing a cap closure.
  • Various pharmaceutically compatible plastics are suitable as the material for the essentially dimensionally stable but not always rigid support part. Since the supporting part as a skeleton does not have to have any significant elastic properties, its selection can be made primarily from the point of view of a material that is well compatible with the container contents. The required elastic properties are generated by the elastic filler. A sprayable rubber compound appears to be particularly suitable for this. The weight proportion of the support part is expediently more than 25% of the proportion of the filler part. As a result, the use of the expensive elastic filling material remains restricted to the areas in which elastic properties for edge sealing or for additional holding of puncture needles must be present.
  • a cap closure can advantageously be produced by covering the sealing element with a closure cap.
  • An expedient method for producing a sealing element of the type described at the outset can be carried out in such a way that in a first operation the support part is molded in one mold recess of a displaceable or rotatable injection mold, and that in the mold recess after the mold has been moved remaining support part is injected in a second operation of the filling part, while a support part is injected in the other mold recess. This enables cyclical work at high working speeds.
  • FIGS. 1 and 2 show a support part 1, which as a skeleton consists of an upper cover part 2 with a flange edge 3 which is open on the underside and a cup-shaped inner wall part 5 which forms part of a hollow insert part 4.
  • a membrane part 6 is molded in one piece into the bottom of the pot-shaped inner wall part 5.
  • connection between the cup-shaped inner wall part 5 and the cover part 2 is made via webs 7 which are integrally connected to the two parts 2.5.
  • the lower edge of the cup-shaped inner wall part 5 is raised with a conical outer wall part 8 up to the sealing surface formed when the plug is completely closed.
  • Injection recesses 9 are located on the cover part 2, through which the material of the filling part can be injected and connected to the support part 1.
  • the embodiment of the complete sealing plug essentially corresponds to FIG. 3.
  • annular reinforcement strips 10, 11 are arranged, which delimit an outer annular puncture surface 12 and an inner circular puncture surface 13.
  • Orientation recesses 15, 16 are formed in the filling part 14 (cf. FIG. 5).
  • a pull-off ring 17 is integrally connected to the cover part 2 via a connecting web 18 for pulling out the sealing plug from the container neck.
  • the dashed position of the pull ring 17 shows the position of use.
  • the height of the pull ring 17 is adapted to the thickness of the cover part 2.
  • the filling part is formed on the cylindrical, solid insertion part 4 as a support layer 19.
  • the connection between the support layer 20 resting on the membrane part 6 and the support layer 19 takes place via passage recesses 21.
  • FIG. 4 shows a support part 1 corresponding to FIG. 3, in which the membrane part 6 is not, however, covered by a support layer of the filling part 14. Rather, in the edge region of the membrane part 6 there is a tube holder 22 with lip seals 23 which clamp a piercing part 24 after the membrane part 6 has been severed and the edge seal.
  • the bearing layer 19 of the filling part 14 is delimited in the edge region of the cylindrical insert part 4 by an integrally molded edge strip 25.
  • the sealing element consisting of a support part designed as an open skeleton and a filler part produced by injection and thereby firmly connected to it, can be used both as part of a cap closure and on its own, i.e. H. can be used without an overlapping cap for closing containers.
  • the overlapping closure cap can also be replaced by an open closure strip, a cover film or the like.
