Abstract

Because known dry closures consisting of a cylinder which is filled in the inside of the closure with drying agent and is closed off by means of a cardboard disc are unsuitable for plastic containers for tablets, dragees and the like and have the disadvantage, inter alia, that the material to be kept dry and lying in the vicinity of the cardboard disc becomes too dry and the material lying in the vicinity of the bottom of the container cannot be kept dry enough, the invention proposes a container or container closure with an insert containing granular drying agent, in which the insert consists of a plastic holding drying agent grains in bound form.

Description

Bei der meist rohrförmigen Verpackung von Tabletten, Dragees, Kapseln oder Perlen wird je nach Art des Füllguts häufig darauf Wert gelegt, daß dieses nicht feucht wird. Ist dies der Fall, muß befürchtet werden, daß trotz eines Schraubverschlusses oder Stopfens, vor allem durch das Öffnen des Behälters, feuchte Luft in das Innere gelangen kann, die ihre Feuchtigkeit an das Füllgut abgibt. Es sind deshalb seit langem sogennante "Trockenverschlüsse" bekannt. Diese bestehen aus einem im Inneren des Verschlusses angebrachten Zylinder, der einen geringeren Durchmesser als der den Behälterrand übergreifende Außenzylinder bei einem Schraubverschluß oder in den Behälterrand eingreifende Außenzylinder bei einem Stopfen aufweist und der mit einem Trockenmittel gefüllt und danach dem Behälterinnenraum zugewandt, durch eine Pappscheibe verschlossen ist. Zweck dieser Maßnahme ist es, die im Behälterinneren entstehende Feuchtigkeit sozusagen "aufzusaugen", d.h. der Wasserdampf dringt durch die Pappscheibe und wird von dem Trockenmittel, z.B. Silikagel oder Tonerde oder Molekularsieb, absorbiert.In the mostly tubular packaging of tablets, dragées, capsules or pearls, depending on the type of filling, it is often important that it does not become damp. If this is the case, it must be feared that despite a screw cap or stopper, especially by opening the container, moist air can get inside, which releases its moisture to the contents. Therefore, so-called "dry closures" have been known for a long time. These consist of a cylinder fitted inside the closure, which has a smaller diameter than the outer cylinder overlapping the container edge in the case of a screw closure or into the container edge engaging outer cylinder in a plug and which is filled with a desiccant and then facing the interior of the container, is closed by a cardboard disc. The purpose of this measure is, so to speak, to "absorb" the moisture which arises inside the container, ie the water vapor penetrates through the cardboard disc and is absorbed by the drying agent, for example silica gel or alumina or molecular sieve.

Es sind ferner aus diesen Trockenverschlüssen entwickelte Trockenmittelzylinder bekannt, die wie die für Verschlüsse vorbeschriebenen aufgebaut sind und dazu dienen, in meist größeren Behältern dem Füllgut zugegeben zu werden.Desiccant cylinders developed from these dry closures are also known, which are constructed like the ones described above for closures and are used to be added to the contents in mostly larger containers.

Der Nachteil dieser Art der Trockenhaltung in einem Arznei- oder Genußmittelbehälter kann in einer sogenannten "Übertrocknung" insbesondere des in der Nähe der im Stopfen zusammengefaßten Trockensubstanz liegenden Füllgutes liegen.
Hierunter wird verstanden, daß der Wasserdampf zu schnell durch die Trennung zwischen Trockensubstanz und Inhalt bildende Pappscheibe diffundiert, die den die Substanz aufnehmenden Zylinder verschließt, wodurch die in der Nähe befindlichen Tabletten, Dragees oder dergleichen zu trocken werden und dann leicht brechen. Dies wird häufig von dem Zustand begleitet, daß der über der Pappscheibe liegende Anteil der Trockensubstanz sehr schnell und intensiv verbraucht wird, wodurch eine Art Barriereschicht entsteht, die das Eindringen weiteren Wasserdampfs verhindert. Die Folge ist, daß das oben in der Nähe der Trockensubstanz liegende Füllgut zu trocken wird und das mehr in der Nähe des Bodens des Behälters liegende Füllgut nicht trocken genug gehalten wird. Besonders nachteilig macht sich dies nach der Erfahrungspraxis bei Gelatinekapseln bemerkbar. Außerdem ist die Herstellung derartiger Verschlüsse kompliziert, weil zuerst der Verschluß gespritzt, dann der Innenzylinder mit Trockensubstanz gefüllt, danach eine Pappscheibe eingelegt und dann, meist durch Umbördelung des Zylinderrandes, die Pappscheibe befestigt werden muß.The disadvantage of this type of keeping dry in a medicament or luxury food container can lie in a so-called "overdrying", in particular of the filling material lying in the vicinity of the dry substance combined in the stopper.
This is understood to mean that the water vapor diffuses too quickly through the separation between the dry substance and the content-forming cardboard disc which closes the cylinder holding the substance, as a result of which the nearby tablets, coated tablets or the like become too dry and then break easily. This is often accompanied by the condition that the portion of the dry matter lying over the cardboard disc is used up very quickly and intensely, as a result a kind of barrier layer is created that prevents the penetration of further water vapor. The result is that the filling material lying near the dry substance at the top becomes too dry and the filling material lying near the bottom of the container is not kept dry enough. This is particularly disadvantageous according to experience with gelatin capsules. In addition, the manufacture of such closures is complicated because first the closure is injected, then the inner cylinder is filled with dry matter, then a cardboard disc is inserted and then, usually by flanging the edge of the cylinder, the cardboard disc has to be fastened.

Hier setzt die Erfindung ein, deren Aufgabe es demnach war, einen Arznei- bzw. Genußmittelbehälter für Tabletten, Dragées, Kapseln und dergleichen zu schaffen, der den gesamten Inhalt trocken hält, ohne daß eine stellenweise Übertrocknung zu befürchten ist und der einfach in der Herstellung ist. Diese Aufgabe löst die Erfindung allgemein dadurch, daß für einen Behälter und dessen Verschluß, insbesondere für Arzneimittel und Genußmittel in Form von Tabletten, Dragées, Kapseln und Perlen, mit einem ein körniges Trockenmittel enthaltenden Einsatz dieser Einsatz für den Behälter und/oder Verschluß aus Kunststoff besteht, in dem die Trockenmittelkörner gebunden aufgenommen, aber in größtmöglicher Menge nicht vollständig eingebettet sind, so daß zumindest ein wesentlicher Teil ihrer aktiven Oberfläche dem Behälterinnenraum frei zugewandt liegt.This is where the invention comes in, the object of which was therefore to create a medicament or luxury container for tablets, dragées, capsules and the like, which keeps the entire contents dry without the risk of over-drying in places and which is simple to manufacture is. This object is generally achieved by the fact that for a container and its closure, in particular for pharmaceuticals and luxury items in the form of tablets, dragees, capsules and pearls, with an insert containing a granular drying agent, this insert for the container and / or closure made of plastic exists in which the desiccant grains are bound but not fully embedded in the largest possible amount, so that at least a substantial part of their active surface is exposed to the interior of the container.

Durch die CH-PS 343 104 ist es zwar bekanntgeworden, sogenannte Weichpackungsmaterialien, z.B. Folien für Suppenbeutel, mit Absorptionsmaterial in feinster Verteilung und durch das Material, in dem das Absorptionsmaterial eingebettet ist selber oder durch eine zusätzliche Schicht geschützt, zu versehen. Die Feinstverteilung des Absorptionsmaterials und dessen vollständige Einbettung, gegebenenfalls unter Verwendung einer, wenn natürlich auch Feuchtigkeit durchlassenden Schutzschicht ist technisch aufwendig und kann die Wirkung des Absorptionsmaterials erheblich einschränken.CH-PS 343 104 has made it known to provide so-called soft packaging materials, for example foils for soup bags, with absorption material in the finest distribution and with the material in which the absorption material is embedded itself or protected by an additional layer. The very fine distribution of the absorption material and its complete embedding, if necessary using a protective layer, which of course also allows moisture to pass through, is technically complex and can considerably limit the effect of the absorption material.

Fig. 1 zeigt einen allgemein mit 1 bezeichneten Behälter aus Kuststoff, insbesondere für während der Aufbewahrung trockenzuhaltende Arzneimittel in Tabletten-, Dragée-, Kapsel und Perlenform, der aber auch für Genußmittel, z.B. sog. Brausetabletten geeignet ist. Er besteht aus dem meist aber nicht immer zylindrischen Hauptkörper 2 mit Boden 3 und einer umlaufenden Ringrille 4 im Randbereich für den Eingriff des Dichtungswulstes eines Verschlußstopfens. Der Behälter kann aber auch am oberen offenen Rand ein Außengewinde aufweisen und mit einer Verschlußkappe verschlossen werden.Fig. 1 shows a container made of plastic, generally designated 1, in particular for medicinal products to be kept dry during storage in tablet, dragee, capsule and pearl form, but which can also be used for stimulants, e.g. so-called effervescent tablets is suitable. It consists of the main body 2, which is usually but not always cylindrical, with a base 3 and a circumferential annular groove 4 in the edge region for the engagement of the sealing bead of a sealing plug. The container can also have an external thread on the upper open edge and be closed with a sealing cap.

Erfindungsgemäß ist der Hauptkörper 2 des Behalters 1 innen mit einer Trockenmittelschicht ausgekleidet, die aus einem Einsatz in Form eines Hohlzylinders 5 besteht.According to the invention, the main body 2 of the container 1 is lined on the inside with a desiccant layer, which consists of an insert in the form of a hollow cylinder 5.

Der Hohlzylinder 5 ist aus einem Kunststoff, z.B. PS, PE oder PP mit Beimischung von Trockenmittel in Körnerform gespritzt, und zwar derart, daß die Trockenmittelkörner im größtmöglichen Umfang gebunden, aber nicht völlig eingebettet sind, d.h. zumindest ein wesentlicher Teil ihrer aktiven Oberfläche dem Innenraum 6 des Behälters zugewandt liegt. Hierzu beträgt die Dicke des Hohlzylinders 5 bei einer Körnergröße des Trockenmittels von 0,5 bis 0,8 mm etwa 1,5 mm, d.h. die Korngröße macht etwa 30 bis 50 % der Zylinderdicke aus. Die Gesamtwanddicke des Behälters kann dann etwa 2 mm betragen.The hollow cylinder 5 is made of a plastic, e.g. PS, PE or PP are injected in the form of granules with the addition of a desiccant, in such a way that the desiccant grains are bound as much as possible, but are not completely embedded, i.e. at least a substantial part of its active surface faces the interior 6 of the container. For this purpose, the thickness of the hollow cylinder 5 with a grain size of the desiccant of 0.5 to 0.8 mm is approximately 1.5 mm, i.e. the grain size is about 30 to 50% of the cylinder thickness. The total wall thickness of the container can then be approximately 2 mm.

Der Einsatz in Form eines Hohlzylinders 5 kann je nach Inhaltsart und -form,d.h. Je nach dem gewünschten Trocknungsgrad,oben und unten offen sein oder, wie dargestellt, einen Boden 7 aufweisen.The insert in the form of a hollow cylinder 5 can be open at the top and bottom depending on the type and shape of content, ie depending on the desired degree of drying, or, as shown, have a bottom 7.

Der Einsatz kann auch aus einem Kunststoff-Trockenmittel-Gemisch bestehen, dem ein geringer Prozentsatz Treibmittel zugemischt wurde.The insert can also consist of a plastic desiccant mixture to which a small percentage of blowing agent has been added.

Das Treibmittel soll also so dosiert zugesetzt werden, daß kein Aufschäumen, sondern nur in gewissem Umfang eine porige Oberflächenstruktur entsteht, d.h. die Trockensubstanz nicht eingebettet, sondern für die Entfaltung ihrer Wirksamkeit für den im Behälter entstehenden Wasserdampf zugänglich bleibt. Damit wird eine direkt zugängliche, das Trockenmittel aufweisende Oberfläche geschaffen, die aber gleichzeitig durch die Tatsache, daß das Trockenmittel nicht kompakt, sondern von Kunsstoff gehalten, vorliegt, eine örtliche übertrocknung vermeidet.The blowing agent should therefore be added in such a way that no foaming occurs, but only to a certain extent a porous surface structure, i.e. the dry substance is not embedded, but remains accessible for the development of its effectiveness for the water vapor generated in the container. This creates a directly accessible surface containing the desiccant, but at the same time avoids local overdrying due to the fact that the desiccant is not compact but held by plastic.

Die Ausführungsform nach Fig. 2 unterscheidet sich von der nach Fig. 1 dadurch, daß die wirksame aktive Oberfläche der im Raum 8 des Behälters 9 wirkenden Trockensubstanz durch eine sich vom Boden 10 des hohlzylinderförmigen Einsatzes 11 erhebenden Stempel vergrößert ist, der je nach Inhaltsart verschieden hoch sein kann.The embodiment according to FIG. 2 differs from that according to FIG. 1 in that the effective active surface of the dry substance acting in the space 8 of the container 9 is increased by a stamp rising from the bottom 10 of the hollow cylindrical insert 11 which differs depending on the type of content can be high.

Für einen Behälter nach den Fig. 1 und 2 kann ein in Fig. 3 im Vertikalschnitt dargestellter Stopfen 13 mit als Handhabe dienender Deckplatte 14 genügen, dessen in den Behälter eingreifender Zylinder 15 einen Dichtwulst 16 aufweist. Wenn die aktive Oberfläche des Trockenmittels so weit wie bei dem Beispiel nach Fig. 1 reicht oder sogar gemäß Fig. 2 noch durch einen Stempel 12 erhöht ist, kann ein Stopfeneinsatz 17 in Form eines Vollzylinders geringer Höhe bzw. einer Tablette ausreichen.For a container according to FIGS. 1 and 2, a stopper 13 shown in vertical section in FIG. 3 with a cover plate 14 serving as a handle, the cylinder 15 of which engages in the container has a sealing bead 16, is sufficient. If the active surface of the desiccant extends as far as in the example according to FIG. 1 or is even increased according to FIG. 2 by a stamp 12, a plug insert 17 in the form of a solid cylinder of low height or a tablet can suffice.

Der Behälter 18 nach Fig. 4 wiest einen hohlzylindrischen Einsatz 19 mit oder ohne Boden auf, der nur einen Teil der Höhe des Hauptkörpers des Behälters einnimmt. In einem solchen Fall kann ein Stopfen 20 nach den Fig. 5 und 6 zweckmäßig sein, dessen Einsatz 21 weiter als der Einsatz 17 des Stopfens 13 nach Fig. 3 in den Innenraum 22 des Behälters 18 nach dem Verschließen eingreift und der über eine große trockenmittelaktive Oberfläche verfügt. Diese wird bei diesem Ausführungsbeispiel dadurch erreicht, daß der Einstz 21 in Form eines in einer Ausnehmung 23 der Unterseite der Deckplatte 24 eingesetzten Zylinders in einzelne aufrechtstehende, im Abstand liegende Scheiben 25a, 25b ... aufgeteilt ist, so daß Zwischenkanäle 26 entstehen, in die im Raum 22 entstehender Wasserdampf eindringen kann.The container 18 of FIG. 4 has a hollow cylindrical insert 19 with or without a bottom, which occupies only part of the height of the main body of the container. In such a case, a stopper 20 according to FIGS. 5 and 6 can be expedient, the insert 21 of which engages further than the insert 17 of the stopper 13 according to FIG. 3 into the interior 22 of the container 18 after the closure and which has a large active desiccant Surface. This is achieved in this embodiment in that the insert 21 in the form of a cylinder inserted into a recess 23 in the underside of the cover plate 24 is divided into individual upright, spaced disks 25a, 25b ... so that intermediate channels 26 are formed in the water vapor arising in room 22 can penetrate.

In den Stopfen kann aber auch, wie in den Fig. 7 und 8 veranschaulicht, ein zylinderförmiger Einsatz 27 eingesetzt sein, der aus konzentrischen Ringen 28a, 28b mit Mittelstempel 29 besteht, zwischen deren senkrechte Wände 30 ebenfalls die gegebenenfalls zu feuchte Luft aus dem Innenraum des Behälters eindringen kann .However, as illustrated in FIGS. 7 and 8, a cylindrical insert 27 can also be inserted into the stopper, which consists of concentric rings 28a, 28b with a central punch 29, between the vertical walls 30 of which the possibly too humid air from the interior of the container can penetrate.

Fig. 7 veranschaulicht auch, daß die Ringe 28 und Stempel 29 unterschiedliche Höhen aufweisen können, ebenso wie dies die Scheiben 25 des Verschlusses nach den Fig. 5 und 6 tun können.FIG. 7 also illustrates that the rings 28 and punches 29 may have different heights, as may the washers 25 of the closure of FIGS. 5 and 6.

Die Unteransicht eines dem Aufbauprinzip den Fig. 7 und 8 folgenden Stopfens 31 gemäß Fig. 9 zeigt, daß z.B. dieRinge 32a, 32b auch Zwischenräume 33,34 bildende Unterbrechungen aufweisen können, um der einströmenden Luft überall Zugang zu verschaffen.The bottom view of a plug 31 according to FIG. 9 following the construction principle of FIGS. 7 and 8 shows that, for example, the rings 32a, 32b can also have interruptions 33.34, in order to provide access to the inflowing air everywhere.

Auch dem trockenzuhaltendem Gut lose beigegebenen Trockenmittelkapseln können nach dem Erfindungsprinzip gestaltet sein und werden auch in diesem Fall durch ihre gegenüber bekannten Kapseln wesentlich vergrößerte aktive Oberfläche eine bessere Trockenhaltung gewährleisten oder in geringerer Zahl zum Einsatz gelangen können. Hierfür können z.B. einfach Einsätze 21 oder 27 nach den Fig. 5 bis 9 verwendet werden.The desiccant capsules loosely added to the material to be kept dry can also be designed according to the principle of the invention and will also ensure better dryness in this case or can be used in smaller numbers due to their active surface, which is significantly larger than known capsules. For this, e.g. simple inserts 21 or 27 according to FIGS. 5 to 9 can be used.

Die dargestellten und vorstehend beschriebenen Beispiele können nur eine kleine Auswahl der Gestaltungsmöglichkeiten wiedergeben, die sich dem Erfindungsgedanken unterordnen. So können selbstverständlich alle dargestellten Behälter mit allen dargestellten Stopfen kombiniert werden, ebenso wie anstelle der dargestellten und beschriebenen Stopfen auch den Behälterrand übergreifende Kappen nach dem Prinzip der Stopfendarstellung erfindungsgemäß mit einem Trockenmitteleinsatz ausgerüstet werden können.The examples shown and described above can only represent a small selection of the design options that are subordinate to the inventive concept. Thus, of course, all of the containers shown can be combined with all of the plugs shown, just as caps instead of the plugs shown and described can also be equipped with a desiccant insert according to the invention, according to the principle of the plug.

Die Einsätze der Behälter müssen nicht durchgehende Zylinder sein, sondern können in Felder oder Streifen aufgeteilt sein, die nur durch ein oder mehrere Ringe zusammengehalten sind. Die Stopfeneinsätze müssen nicht kreisrund sein, sondern können jede andere Form, z.B. quadratische haben.The inserts of the containers do not have to be continuous cylinders, but can be divided into fields or strips which are only held together by one or more rings. The plug inserts do not have to be circular, but can have any other shape, e.g. have square.

Die Herstellung eines Behälters oder Verschlusses nach der Erfindung kann in der Weise erfolgen, daß zunächst ein Einsatz auf einer Maschine gespritzt wird und in derselben oder einer anderen um diesen herum der Behälter vervollständigt wird. Dadurch kann der Arbeitsaufwand gegenüber dem Füllen eines im Verschluß befindlichen Zylinders mit Trockenmittel, Verschließen durch eine Pappscheibe und Befestigen der Scheibe wesentlich verringert werden.The manufacture of a container or closure according to the invention can be carried out by first injecting an insert on a machine and completing the container in or around the machine. As a result, the workload compared to filling a cylinder in the closure with desiccant, sealing with a cardboard disc and fastening the disc can be significantly reduced.
