Definitions
- the invention relates to a closure for medication bottles, which has a pierceable sealing insert which is held by an externally heat-sealable closure cap which has an opening which is closed before use with a plastic cap seated on the closure cap.
- the closure is intended to ensure the originality of the sealed medication bottle.
- Closures for medication bottles in various designs are already known, in which an opening of a crimp cap is released by tearing off or pulling out a plastic cap.
- axial extensions of the plastic caps penetrate the openings of the crimp caps and engage behind them in a form-fitting manner.
- the sealing cap which is usually designed as a crimp cap, is then exposed, for example, by pulling out the plastic cap (cf. DE-PS 26 28 771).
- the opening of the closure cap is uncovered by tearing out one connected to the rest of the closure cap by bridges Ringes (cf. DE-PS 1 207 043).
- closures still have considerable disadvantages.
- the above-mentioned closures have the disadvantage in common that there is no hermetic sealing between the plastic cap and the usually made of aluminum closure cap, so that e.g. During the sterilization, water vapor or during storage, dirt and germs can get between the closure cap and the plastic cap, which can lead to highly undesirable contamination at the puncture point of the closure.
- the closure there has a closure cap made of aluminum, the later opening of which is also predetermined by scratches in the closure cap, an axial, outwardly directed projection being provided within the predetermined breaking point. This is inserted through the opening of a plastic disc and then riveted to it by spreading out the projecting part.
- This closure has the particular disadvantage that the extreme when riveting sensitive predetermined breaking points can be injured, so that a hermetically sealed closure is no longer guaranteed.
- a plastic cap with a sealing cap is hermetically welded along a zone that runs back in the circumferential direction and is approximately linear in its radial extent.
- Such a hermetically sealed connection between the closure and the plastic cap prevents dirt, germs or water vapor from reaching the opening of the closure, which later represents the puncture point of the closure.
- the narrow, practically linear welding zone still allows the closure to be torn open by hand.
- the welding zone can advantageously be arranged at a certain distance from the edge of the opening of the closure cap. This has the advantage that the edge of the opening is not affected by the tearing open, so that when the medication bottle provided with such a closure is put into use, it is possible to disinfect the puncture point when the closure cap is opened with a cotton ball.
- a particularly advantageous development of the invention is that the welding of the cap on a ring around the cap opening of the cap and pointing away from the inside of the bottle, for. B. circular bead.
- This version is particularly good adjustable.
- a somewhat modified, advantageous embodiment of the invention consists in that the welding of the closure cap takes place in a ring around the cap opening of the closure cap and points in the direction of the inside of the bottle, with a ring of the plastic cap protruding correspondingly in the direction of the inside of the bottle engaging in this bead and is welded there.
- beaded versions of the closure cap there are several advantages. Depending on the depth and shape of the bead, it is possible to set the tearing force smaller or larger.
- the bead When the bead is molded into the closure cap, which is generally made of metal, preferably aluminum, according to the invention, the bead is thinned in a specific manner in a specific cross-sectional area; this enables a faster heat transfer at the thinned points of the sealing cap when a welding stamp is applied, so that it is possible to make the radial extent of the welding zone almost linear.
- This not only provides a hermetically sealed connection between the plastic and the closure cap, but also achieves an almost linear, easily tearable connection of the aluminum cap with the plastic cap and at the same time geometrically sufficiently precise conditions for tearing off the closure cap.
- the invention also relates to a method for producing a closure of the type mentioned at the outset, the task according to the invention being analogous to that which has already been explained above in connection with the closure.
- the solution of the method according to the invention Make such a closure is in particular that on the closure cap a thinned, along a in the circumferential direction, in its radial extent approximately linear wall area, preferably in the form of a bead, formed on this closure cap and then taking advantage of the comparatively faster heat transfer during thinned wall area a radial line-shaped welding zone between the closure and the plastic cap is produced.
- Fig. 1 shows the mouth 1a of a medication bottle 1, which is closed with a closure designated as a whole by V.
- the closure V includes an elastic sealing part 2, which is held on the bottle 1 by a closure cap 3 made of aluminum.
- This cap 3 has a central opening 5, which is closed by a plastic cap 4 before use.
- the bead 6 is circular. It could also have a different, receding, for example oval or elliptical shape.
- a bead 6 which is circular in the circumferential direction and a correspondingly designed welding zone is particularly advantageous. It is also part of the invention that the welding zone 20 is very narrow in its radial extent, 5 is practically approximately line-like, as can be seen particularly well from FIG. 5, the strong, non-scale enlargement according to FIG. 5 also having to be taken into account.
- Fig. 5 shows a longitudinal section through the bead 6 of the cap corresponding to the section A in Fig. 1. In Fig.
- FIG. 2 shows a perspective view of the closure cap 3 with the central opening 5 and the bead 6 arranged coaxially thereto.
- the radial distance a between the edge 5a of the opening 5 on the one hand and the bead 6 on the other hand can be clearly seen.
- Fig. 3 shows a perspective view of a slightly modified cap 3 '. It differs from the closure cap 3 already described, particularly clearly visible in FIG. 2, above all in that - starting from the cap opening 5 - incisions 7, 7a and. 7b are attached. Such incisions for breaking open and easy removal of caps, especially metallic caps, are known per se. 3, a bead section 6a lying between two adjacent incisions 7a and 7b is widened. This allows you to connect the plastic cap 4 in the area of this widened bead portion 6a more firmly with the closure cap 3 ', because a widened welding zone section 21 is available for this connection compared to the rest of the welding zone 20.
- the closure cap 3 shows a situation when the closure cap 3 is torn open, which can be easily removed from the mouth 1 a of the bottle 1 after corresponding tearing of incisions 7, 7a, 7b. 4, the bead 6 with corresponding bead sections 6b and dashed lines in FIG. 4, the separated welding zone 20, can be seen clearly. There it can also be clearly seen that the plastic cap 4 has a recess 9 opposite the widened welding zone section 21 as a finger insert. This can both facilitate operation and indicate the direction in which it is torn open.
- Fig. 6 shows in a similar representation as Fig. 1, a closure V '.
- a bead 10 in the cap 3a, which is directed towards the inside of the bottle.
- an annular elevation 11 which fits into this bead 10.
- the bead has, at least over a large part of its circumferential area, a substantially smaller wall thickness d compared to the wall thickness D of the sealing capsule 3 'in the area outside of its bead 10.
- the elevation 11 of the plastic cap 4' is designed in such a way that that they are only in ver
- the thin portion 11a of the bead 11 rests and can be welded in a ring-like manner in the manner of the material thinning in the manner already mentioned.
- FIG. 7 shows an enlargement of the corresponding area of bead 10 and the welding zone 20a there, designated B in FIG. 6.
- the wall thickness D of the undeformed sealing cap 3 is thinned to a thickness d at the welding zone (20, 20a).
- This thinning takes place in such a way that the plastic cap 4 is hermetically welded on a self-contained line or area of small radial expansion and can be torn off the cap 3 again by pushing it up.
- the position and extent of the welding zone being defined in such a way that the force for pushing up and tearing off is between 5-200 Newtons (N), preferably between 10 and 25 N.
- the cap 3 is regularly made of metal, preferably of aluminum. 3 and 4, the cap 3 made of aluminum can be easily broken open so that it can be easily removed from the mouth end of the bottle 1 as a crimp cap. 2 that the bead 6 is arranged at a radial distance a from the inner edge 5a of the opening 5 of the cap 3.
- a suitable shaping of the deep-drawing die forming the cap 3 attaches a self-tapering, thinned wall area in the form of an axially outwardly or inwardly projecting bead (6, 10).
- the plastic cap 4 is provided with a recess 15 or elevation 11 matching the bead 6 or 10.
- the two parts 4 and 4 'and 3 or 3' placed against one another (see FIGS. 1 and 5 on the one hand and FIGS.
- the radial width of the welding zone 20, 20a of the closure cap 3 is, depending on the diameter of the cap 3, 0.5 to 3.5 mm, preferably 1, 2 to 2.5 mm. The smaller values mentioned above apply to smaller cap diameters.
- the ratio of the wall thickness D of the undeformed closure cap 3 to the wall thickness d in the area of the bead 6, 10 and there in particular in the area of the welding zone 20, 20a D: d is between 1.1 to 1.5, preferably at 1, 25 to 1.5 selected.
- the distance a of the bead 6, 10 from the edge 5 'of the opening 5 of the cap is, depending on the size of the cap 3, between 0.1 and 10.00 mm, preferably between 0.3 and 1.0 mm.
