Definitions

  • the invention relates to a closure for a bottle, comprising a cup-shaped closure cap with at least one puncture-side puncture opening and a pierceable sealing element made of elastomeric material which covers the puncture opening in a sealing manner, the bottle having a bottle neck with an at least partially circumferential and bead-shaped fastening flange, which can be joined together with the open, front edge of the closure cap.
  • Such a closure is known from DE 38 35 720 A1.
  • the cap of the closure is manufactured and in a further manufacturing step in the same tool or a part thereof, the elastic sealing element is injected into the cap.
  • the sealing element welds firmly and inseparably to the polymeric material of the cap.
  • the cap is provided with a recess in the region of its base, the recess being filled with the elastomeric material of the sealing element in order to achieve a flush surface on the side of the cap base facing away from the bottle.
  • the sealing element is exposed to tensile stresses which reduce the service life due to the manufacturing process and which can lead to detachment from the polymeric material of the closure cap. Such detachment affects the sterile sealing of the bottle contents and can lead to contamination of the environment through leakage during the removal of the liquid.
  • the cap and the bottle are made of a thermoplastic elastomer and are welded together.
  • the invention has for its object to further develop a closure of the known type such that a reliable and secure sealing of the bottle contents is guaranteed even during its removal and that the sealing element closes the puncture site automatically and completely after pulling out a removal spike.
  • the closure cap comprises an inner and an outer shell, which has a substantially identical shape and can be fixed one inside the other with axial and radial compression of the disk-shaped sealing element, and that the sealing element is in one piece with the inside - Or the outer shell formed, annular and projecting in the direction of the outer or inner shell is arranged.
  • the sealing element is formed by a separately produced individual part and is fixed in a sealed manner between the two shells in the state mounted on the bottle with all-round prestressing.
  • the pressure bias acting on all sides of the sealing element on the one hand results in a reliable seal of the bottle contents from the environment and on the other hand that infusion spikes, whose diameter does not exceed 5 mm, can be removed from the cap and then the puncture site of the sealing element by the pressure bias automatically closes again liquid-tight.
  • Such usage properties are particularly advantageous when the contents of the bottle to be closed are not to be removed completely and the bottle, which is only partially emptied, is to be disposed of.
  • a leakage barrier for opened medication bottles is of particular advantage.
  • the inner shell can be provided with the receptacle on the side facing away from the bottle, the receptacle completely enclosing the sealing element and being guided on the outside in a bulge in the outer shell. It is advantageous here that displacements of the inner shell and / or the sealing element transversely when the infusion spike is inserted and its subsequent loading for the piercing direction can be reliably avoided.
  • the sealing of the contents of the bottle is therefore always of the same quality.
  • assembly errors during the fitting together of the individual parts of the closure cap are minimized by such a configuration.
  • the inner and outer shells as well as the sealing element form a preassembled unit, the inner and outer shells being able to be snapped into one another in a form-fitting manner by means of a captive lock, with the tensioning element being inserted essentially without tension. Relaxation phenomena of the sealing element when the closure cap is not yet assembled can thereby be avoided. Due to the loss-proof interconnected parts of the cap, this can be placed uniformly and easily on the bottle and connected to it. When the bottle is closed, the preassembled unit, consisting of the outer and inner shell, is put together with the sealing element inserted without tension.
  • the unit is then placed on the bottle and pressed with elastic open and radial deformation of the sealing element with the open end of the cap onto a mounting flange of the bottle.
  • the cap can then be welded to the bottle, the outer and inner shells being welded to one another and to the fastening flange at the same time.
  • the captive device can be formed by a depression into which a projection can be snapped, the depression and the projection being arranged on the mutually facing peripheral regions of the inner and outer shells.
  • the outer shell on the side facing the inner shell can have a groove-shaped circumferential recess, which can be brought into engagement with a bead-shaped circumferential projection of the inner shell, the recess and the projection being formed in one piece with the outer and the inner shell according to an advantageous embodiment are.
  • the simple, low-part construction of the closure cap is advantageous in terms of assembly technology and economy.
  • the depression and / or the projection can be fixed to one another by an elastically flexible expansion and / or deflection in the form of a clip connection.
  • the outer shell can completely cover the sealing element and can be provided with at least one puncture point of reduced material thickness.
  • the advantage here is that the surface of the outer shell is essentially flat and can therefore be disinfected with a disinfectant without any problems before the infusion spike is inserted.
  • the comparatively more open-pored surface of the sealing element is protected from contamination during storage of the closed bottle and is arranged aseptically within the closure cap.
  • the puncture point of the outer shell has a comparatively relatively reduced material thickness.
  • the reduced material thickness is preferably achieved by maintaining the largely flat surface of the outer shell on the side facing away from the bottle and reducing the thickness of the material on one side on the side facing the sealing element, so that a cavity is formed between the sealing element and the adjacent outer shell becomes.
  • the cavity promotes a low-force piercing and an exact positioning of the infusion spike due to its elastic deformation during the piercing process.
  • the outer shell can be provided on the side facing away from the bottle with at least one marking which identifies the puncture site. Such a marking can be carried out, for example, by means of a contrastable marking which differs from the color of the Lift off the outer shell and / or by embossing the surface of the outer shell.
  • the inner shell can be provided with at least one recess which has a shape which essentially corresponds to the puncture points and is assigned concentrically to this.
  • the inner shell can be provided with at least one recess which has a shape which essentially corresponds to the puncture points and is assigned concentrically to this.
  • the outer shell / or the inner shell can be provided with integral, wedge-shaped sealing lips which sealingly touch the sealing element and enclose the puncture point and / or the recess.
  • the wedge-shaped design of the sealing lips causes a high surface pressure on the surface of the sealing element and thus an excellent seal.
  • the sealing lips provide additional security against loss of liquid, since a flat support of the sealing element between the outer and the inner shell leads to a good sealing result.
  • the closure cap and the bottle can preferably consist of the same material from polymeric material, the closure cap being weldable to the fastening flange of the bottle.
  • a thermoplastic elastomer such as polypropylene or polyethylene, can be used as the material for the bottle and the cap. This ensures good recyclability of the materials.
  • a bottle 1 is shown, which is designed as an infusion bottle with pharmaceutical content and consists of polypropylene.
  • the bottle 1 with its cap 2 is arranged in a hanging manner, the bottle content being removed as an infusion through an infusion spike 19.
  • the infusion spike 19 is enclosed by the first piercing opening 3 of the closure cap 2 and is automatically held in its position by a non-positive connection to the inner shell 8, the sealing element 4 and the outer shell 9.
  • a second piercing opening 21 is provided which surrounds a cannula 20 in order to be able to supply additional active substances to the bottle contents.
  • the inner shell 8 and the outer shell 9 are both essentially pot-shaped, the sealing element 4 being arranged in an annular receptacle 10 on the side of the inner shell 8 facing the outer shell 9.
  • the annular receptacle 10 is guided on the outer circumferential side by the bulge 11 of the outer shell 9.
  • the sealing element 4 is accommodated in the radial and axial direction under prestress within the closure cap 2.
  • the radial and axial preload of the sealing element 4 is dimensioned such that its puncture openings are automatically closed again after the spike 19 and the cannula 20 have been removed. This leakage barrier is particularly useful if not all of the liquid is removed from the bottle 1.
  • Escaping liquid when the infusion spike 19 and the cannula 20 are removed can thereby also be avoided in the hanging position of the bottle 1 and subsequently during its disposal.
  • the bottle neck 5 of the bottle 1 is provided with an annular fastening flange 6, which is welded to the edge 7 of the closure cap 2, which is open at the end, in a liquid-tight manner.
  • FIG. 2 shows the detail "Y" of the closure cap 2 from FIG. 1 in an enlarged view.
  • the sealing element 4 is arranged under radial and axial prestress between the inner 8 and the outer shell 9, the cannula 20 penetrating the puncture point 16 of the outer shell 9 and the recess 17 of the inner shell 8 and the sealing element 4.
  • the outer shell 9 and the inner shell 8 are provided with integrally molded, wedge-shaped sealing lips 18, which are pressed into the elastically flexible material of the sealing element 4 pressed on all sides.
  • the outer shell 9 and the inner shell 8 are welded to one another and together with the fastening flange 6 of the bottle neck 5.
  • the cap 2 is shown as a pre-assembled unit 12, consisting of the inner shell 8, the sealing element 4 and the outer shell 9 in a cross-sectional view.
  • the captive lock 13 is formed by a groove-shaped recess 14 which is arranged on the side of the outer shell 9 facing the inner shell 8 in the region of the end face facing the fastening flange 6.
  • the inner shell 8 is provided with a protrusion 15 which extends in the form of a bead and which is snapped into the depression 14.
  • the outer shell 9 is provided with a bulge 11, which serves as a guide for the receptacle 10 of the inner shell 8 and completely covers the sealing element 4 on the outside.
