Abstract

A process for filling and sealing a vessel which is formed of starch or at least one other hydrophilic material, or a mixture of compounds of this nature, and which comprises a container part and a closure part, the container part and closure part being capable of cooperating along respective mating areas to provide a non-locking mating free of any snap-lock, comprising: (a) introducing a product constituting the filling into the container part of the vessel; (b) bringing a sealing liquid into contact with the whole or a portion of that mating area of the closure part which touches the mating area of the container part when the vessel is in the closed state, and/or with the whole or a portion of that mating area of the container part which touches the mating area of the closure part when the vessel is in the closed state; and (c) subsequently uniting the container part and the closure part in order to form the sealed vessel. <IMAGE>

Description

       

  
 



  Es ist bekannt, druckgeformte Formkörper aus natürlicher Stärke und hydrophilen Materialien, wie beispielsweise Gelatine, mittels Spritzgiessen herzustellen. Bevorzugt werden solche Behälter hergestellt für das Befüllen mit Pharmazeutika, Esswaren, Chemikalien, u.a.m., insbesondere als pharmazeutische Kapseln, für die dosierte Verabreichung von Medikamenten. Diese Behälter bestehen aus einem Hauptteil und einem Verschlussteil, wobei regelmässig mindestens einer der beiden Teile und in der Regel beide Teile miteinander passenden Hinterschneidungen versehen sind, um einen Schnappeffekt und dadurch einen guten Verschluss derselben zu gewährleisten. Pharmazeutische Kapseln sind von relativ kleiner Dimension. Der Schnappeffekt ist von besonderer Wichtigkeit, weil dieser bei abgefüllten pharmazeutischen Wirkstoffen ein zufälliges oder auch absichtliches \ffnen der Kapseln verhindern muss.

  Gemäss den heute bekannten Methoden wird, entsprechend der Grösse der pharmazeutischen Kapsel, der Schnappverschluss durch eine Hinterschneidung hoher Präzision von ca. 0.03 mm bis 0.15 mm im Hauptteil und/oder im Verschlussteil erreicht. Eine kleinere Hinterschneidung bewirkt einen mangelhaften Verschluss; eine zu grosse verursacht Risse vor allem im Hauptteil. 



  Auch exakt gearbeitete Hinterschneidungen sind mit diversen Nachteilen behaftet. Die Wandstärke einer pharmazeutischen Kapsel ist möglichst dünn zu halten. Als Folge ergeben sich verschiedene Wandstärken des Haupt- und des Verschlussteils. Dadurch ergibt sich eine unterschiedliche Dimensionsdynamik dieser beiden Teile was besonders bei veränderlicher Luftfeuchtigkeit zu einer unterschiedlichen Geometrie beider Teile und zu Spannungen führt. 



  Diese kann unter Umständen das Sprengen der Kapseln verursachen. Abgefüllte Pulver oder Flüssigkeiten laufen dann aus. Insbesondere auch in der Abfüllmaschine können beim Schliessen der Kapseln Schwierigkeiten entstehen. 



  Die Herstellung von Hinterschneidungen ist aber auch technisch aufwendig. Insbesondere sind Schieber- oder Backenwerkzeuge notwendig, wobei sodann Schiebermarkierungen als Unebenheiten auf der Kapseloberfläche erscheinen. Durch die notwendigen Schieber oder Backen hat das Werkzeug mehr gleitende Teile, höheren Verschleiss, höhere Drucke bzw. Schliesskräfte, höhere Fehleranfälligkeit und damit erhöhte Stillstandzeiten und Betriebskosten. Zusätzlich verursachen Schieber eine gewisse Destabilisierung des Werkzeugs. Insbesondere können auch weniger Kavitäten pro verfügbare Fläche angebracht werden, was den Ausstoss erheblich vermindert. 



  Es wurde nun gefunden, dass sich alle diese genannten Nachteile beheben lassen, wenn man eine druckgeformte Kapsel im Abfüllprozess verwendet, welche keine Hinterschneidungen aufweist und diese Kapsel wie im weiteren beschrieben in erfindungsgemässer Weise versiegelt. 



  Die Erfindungsdefinition ist dargestellt in den Patentansprüchen 1, 13, 14, 16. Besondere Ausführungsformen sind in den abhängigen Patentansprüchen dargestellt. 



  Unter Stärke ist das natürlich vorkommende pflanzliche Kohlehydrat zu verstehen, welches zur Hauptsache aus Amylose  und Amylopektin besteht. Sie wird z.B. aus Kartoffeln, Reis, Tapioca, Mais, Korn wie Roggen, Hafer, Weizen und anderen Pflanzen gewonnen. Solche Stärke lässt sich unter Anwendung von Druck und erhöhter Temperatur zu kompakten Formkörpern hoher Präzision verarbeiten. Das Herstellungsverfahren für das Druckformen insbesondere für das Spritzgiessen unter Druck und erhöhter Temperatur, d.h. die Verfahrensbedingungen sowie die möglichen Zusätze wie Streckmittel, Gleitmittel, Weichmacher und/oder Farbstoffe sind in der Europäischen Patenanmeldung Nr. 84 300 940.8 (Publ. Nr. 118 240) beschrieben und gelten auch für die vorliegende Erfindung. 



  Unter dem Ausdruck "hydrophile Materialien" sind solche hydrophilen Materialien zu verstehen, die für die Herstellung der erfindungsgemässen Behälter, insbesondere von pharmazeutischen Kapseln, geeignet sind. 



  "Hydrophile Materialien" sind polymere Materialien wie beispielsweise Gelatine; pflanzliche Proteine wie Sonnenblumen-, Baumwollsamen-, Erdnuss-, Rapssamenproteine; Blutproteine; Eiproteine; acylierte Derivate der vorgenannten Proteine; Alginate; Lactose; Gummi Arabicum  wasserlösliche Derivate der Cellulose, wie z.B.

Solche sind z.B. Hydroxpropylmethylcellulosephthalat (HMPCP), Polyvinylacetatphthalat (PVAP), Celluloseacetylphthalat (CAP), kationisch modifizierte Acrylate  und Methacrylate z.B. mit einer tertiären oder quaternären Aminogruppe, wie die gegebenenfalls quaternierte Diäthylaminoäthylgruppierung; Gelatine-phthalate; Gelatine-succinate u.a. Bevorzugt ist Gelatine. 



  Die Herstellungsverfahren für das Druckformen solcher hydrophilen Materialien insbesondere für das Spritzgiessen unter erhöhtem Druck und erhöhter Temperatur, d.h. die Verfahrensbedingungen sowie die möglichen Zusätze wie Streckmittel, Gleitmittel, Weichmacher und/oder Farbstoffe sind in der Europäischen Patentanmeldung Nr. 8 301 643.9 (Pupl. Nr. 090 600) beschrieben. 



  Die in den beiden vorgehend genannten Europäischen Patentanmeldungen Nos. 84 300 940.8 und  83 301 643.9 beschriebenen Details für die Herstellung solcher druckgeformten Behälter, insbesondere druckgeformte vorzugsweise spritzgegossene pharmazeutische Kapseln, gelten auch für die vorliegende Erfindung und sind Teil derselben. In der vorliegenden Erfindung werden derart erhältliche druckgeformte Behälter, vorzugsweise pharmazeutische Kapseln, verwendet, die hinterschneidungsfrei sind. 



  Als mögliche Streckmitttel sind die oben genannten Materialien zu nennen, d.h. Stärke oder ein anderes der "hydrophilen Materialien", wobei diese als Zusätze die Funktion einer Mischkomponente oder Streckmittel übernehmen. Streckmittel sind aber auch anorganische Füllmaterialien wie Oxide des Magnesiums, Aluminiums, Siliziums, Titans u.a. Für Streckmittel sind Konzentrationen von bis zu 50% angezeigt, vorzugsweise 3-10%, bezogen auf das Gewicht aller die Behälterwand bildenden Komponenten. 



   Weichmacher sind beispielsweise Polyalkylenoxide, wie Polyäthylenglykole, Polypropylenglykole, Polyäthylen-propylenglykole; niedrigmolekulare organische  Weichmacher  wie  Glycerin, Glycerinmono-, - di- und -triacetat; Propylenglykol, Sorbitol, Natrium-diaethylsulfosuccinat, Triäthylcitrat, Tributylcitrat u.a. in einer Konzentration von 0,5-15%, bezogen auf das Gewicht aller Komponenten. 



  Farbstoffe sind beispielsweise bekannte Azofarbstoffe oder organische oder anorganische Pigmente, oder natürlich vorkommende Farbstoffe. Bevorzugt sind anorganische Pigmente, wie die an sich bekannten Oxide des Eisens oder des Titans in einer Konzentration von 0.001-10%, vorzugsweise 0.5-5%, bezogen auf das Gewicht aller die Behälterwand bildenden Komponenten. 



  Bevorzugt haben die aus Stärke und/oder den anderen hydrophilen Materialien geformten Behälter einen Wassergehalt von 10-20%, vorzugsweise 12-19% und insbesondere 14-18%, bezogen auf das Gewicht aller die Behälterwand bildenden Komponenten. 



  Bevorzugt beträgt die Summe von Weichmacher und Wasser höchstens 25%, vorzugsweise höchstens 20%, bezogen auf das Gewicht aller die Behälterwand bildenden Komponenten. 



  Der im weiteren gebrauchte Ausdruck "Kapseln" bedeutet ebenfalls Behälter irgendwelcher Art gemäss der oben erwähnten Definition. 



  Das Spezielle an den Kapseln der vorliegenden Erfindung im Vergleich mit der EP 84  300 940.8 (118 240) und der EP 83 301 643.9 (060 900) ist, dass die Kapseln der vorliegenden Erfindung keine Hinterschneidungen und somit auch keine Schnappverschlüsse irgendwelcher Art aufweisen. Bevorzugt sind solche Kapseln, bei welchen sich der Hauptteil und der Verschlussteil verformungsfrei zusammenfügen lassen. Solche Kapseln sind neu und Gegenstand der vorliegenden Erfindung. Verschlossene Kapseln der vorliegenden Erfindung weisen bevorzugt zu allen Stellen eine praktisch gleiche Wandstärke auf, so dass Spannungen infolge unterschiedlicher Dimensionsdynamik vermieden werden. 



  Kapseln der vorliegenden Erfindung lassen sich einfach herstellen, füllen und verschliessen. Durch den fehlenden Schnappverschluss lassen sie sich jedoch relativ einfach öffnen oder öffnen sich von selbst bei der weiteren Behandlung, insbesondere wenn der Hauptteil und der Verschlussteil zwar mit hoher Präzision jedoch verformungsfrei ineinandergefügt sind. In der Regel sind die ineinandergeschobenen Flächensegmente nur 0.5 mm bis maximal 2 mm hoch. 



  Es war deshalb überraschend festzustellen, dass sich die Kapseln nicht öffnen, wenn man mindestens eine der sich berührenden Flächen des Hauptteiles oder des Verschlussteiles vor dem endgültigen Verschliessen mit einer Versiegelungsflüssigkeit in Berührung bringt. 



  Bevorzugt enthält diese Versiegelungsflüssigkeit Wasser. Bevorzugt ist dies ein Gemisch von Wasser und einem Alkohol, vorzugsweise einen solchen mit 1-4 C-Atomen, vorzugsweise Aethanol, Propanole und Butanole, insbesonere Aethanol oder Isopropylalkohol, vorzugsweise Aethanol, in einem Wasser/Alkohol-Verhältnis von 95:5 bis 40:60, vorzugsweise ca. 80:20 bis 60:40, vorzugsweise ca. 70:30. 



  Weitere wässrige Versiegelungsmittel sind zum Beispiel wässrige Lösungen von Saccharose, Stärke, Mono-, Oligo- und Polysaccharide, Glycerin und andere Polyole, Glycol, Polyglikole von Aethylenglykol und/oder Propylenglykol, an sich bekannte anionische, kationische oder amphothere oberflächenaktive Mittel, Gelatine, Polyvinylalkohole, wasserlösliche anionische oder kationische Acrylpolymere in einer Konzentration von 0.5-10 Gewichtsprozent vorzugsweise 1-4 Gewichtsprozent, bezogen auf das Gesamtgewicht der Versiegelungsflüssigkeit. 



  Bevorzugt ist das oben erwähnte Wasser/Aethanolgemisch. 



  Wasser alleine beispielsweise bewirkt eine übermässige oder unpräzise Benetzung, was eine Schädigung des Füllgutes oder der Kapsel zur Folge hat. Infolge der hohen Empfindlichkeit der Kapselwand gegenüber Wasser, muss die Versiegelungsflüssigkeit eine präzise örtliche und mengenmässige Benetzung erlauben. 



  Natürlich braucht es eine gewisse Zeit, bis ein Versiegelungseffekt eintritt. Es war deshalb überraschend festzustellen, dass sich die erfindungsgemässen Kapseln ohne irgendwelche \ffnungserscheinungen weiter verarbeiten und verpacken liessen. 



  Durch das genaue örtliche und dosierte Aufbringen der Versiegelungflüssigkeit wird eine exakte und flüssigkeitsdichte Versiegelung erreicht. Die Kapsel kann nach der Versiegelung nur durch Zerstörung geöffnet werden. 



  Um eine schnellere Versiegelung zu erreichen, kann man auch die verschlossene Kapsel bzw. die Verschlussstelle erwärmen. Jede Wärmequelle, welche die Kapsel oder deren Inhalt nicht beschädigt, kann verwendet werden, wie z.B Konventionswärme, wie erwärmte Luft; elektromagnetische Strahlung einer geeigneten Frequenz, z.B. Mikrowellen oder Infrarot-Strahlung oder Ultraschall, wobei die erzeugte Temperatur unkritisch ist, vorausgesetzt, dass keine Schädigung der Kapsel oder deren Inhalt verursacht wird. Eine Beschleunigung der Versiegelung durch solche zusätzlichen Massnahmen ist allerdings nur nach Bedarf nötig. Eine Erwärmung auf 30 bis 50 DEG C genügt in der Regel. 



  Das Füllgut kann fest, pastös oder flüssig sein. Die Füllinhalte für pharmazeutische Kapseln sind an sich bekannt und entsprechen den Stoffen, welche mit der Kapselwand verträglich sind und die üblicherweise in pharmazeutische Hartgelatinekapseln abgefüllt werden. 



  Durch die Verwendung der erfindungsgemässen Kapseln und deren Versiegelung ergeben sich neben der Behebung der eingangs genannten Nachteile noch weitere unerwartete Vorteile. So gelingt es, die Wandstärke der Kapsel stark zu reduzieren, da die mechanische Beanspruchung durch den Schnappverschluss entfällt. Dies bedingt eine bedeutend erhöhte \ffnungs- und Auflösungsgeschwindigkeit der Kapsel im Magen- oder Darmsaft sowie auch eine Materialersparnis und bessere Volumenausnützung der Kapsel. 



  In den dieser Erfindungsbeschreibung beigefügten Figuren 1, sind die folgenden Teile erläutert: 
 
   Fig. 1 zeigt die Seitenansicht einer erfindungsgemässen Kapsel, 
   Fig. 2 zeigt den Längsschnitt einer erfindungsgemässen Kapsel gemäss Linie II-II in Fig. 1, 
   Fig. 3 (a) bis (u) zeigt verschiedene Ausführungsformen des spannungslosen Verschlusses des Hauptteiles mit dem Verschlussteil entsprechend dem Hinweis III in Fig. 2, 
   Fig. 4 zeigt eine Ansicht einer Abfüll-/Versiegelungsmaschine für die erfindungsgemässen Kapseln von oben, 
   Fig. 5 zeigt die mit der Abfüll-/Versiegelungsmaschine verbundene Benetzungsstation im Schnitt, gemäss der Linie V-V in Fig. 4 und 
   Fig. 6 zeigt eine perspektivische Abbildung einer Abfüllmaschine, d.h. eine Maschine gemäss Fig. 4 mit Benetzungsstation. 
 



   Fig. 1 zeigt eine Aufsicht einer druckgeformten Kapsel (20), welche im Prinzip ganz unterschiedliche äussere Formen haben kann, wie dies ganz allgemein für Behälter und im speziellen für Kapseln bekannt ist. Fig. 1 ist lediglich eine der  zahlreichen an sich bekannten äusseren Formen. 



  Fig. 2 zeigt den Querschnitt einer erfindungsgemässen Kapsel (20) wobei der hinterschneidungsfreie Verschluss mit Bezug auf Fig. 3 speziell angedeutet ist. Verschlussteil (21) und Hauptteil (22) sind spannungslos ineinandergefügt. 



  Fig. 3 (a) bis (u) zeigt Beispiele hinterschneidungsfreier Verschlüsse, wobei der obere Abschnitt (22) jeweils zum Verschlussteil und der untere (24) zum Hauptteil gehört, wie dies in Fig. 2 gezeigt ist. 



  Fig. 4 zeigt das Muster einer Abfüllmaschine im horizontalen Querschnitt mit einer Versiegelungsstation. Dabei ist der Vorratsbehälter (1) mit einer Transportrinne (2) verbunden, welche die Hauptteile unter Vibration zur Hauptteil-Aufgabestation (3) führt. In dieser Hauptteil-Aufgabestation (3) werden die Hauptteile mit der \ffnung nach oben durch den Stössel (3a) in den Hauptteilhalter (5) gedrückt. Der Hauptteilhalter (5) ist fest montiert am Drehteller (4). Die Hauptteile werden nun durch Drehung des Drehtellers taktweise zur Füllstation (6) transportiert und dort mit einer dosierten Menge eines Pulvers (19), einer Paste oder einer Flüssigkeit aus einem Vorratsbehälter (6a) gefüllt. Der gefüllte Hauptteil wandert anschliessend taktweise zur Verschliess-Station (7).

  In dieser werden die vom Verschlussteil-Vorratsbehälter (10) mittels Vibration durch die Transportrinne (9) herangeführten Verschlussteile über den Drehstern (8) nach der Benetzung durch den Filz (12a) auf die Hauptteile mittels des Verschlussteilhalters (8a) aufgesetzt. Nach taktweisem Weitertransport wird der geschlossene Behälter, im vorliegenden Fall eine pharmazeutische Kapsel an der Auswerfstation (11) aus dem Hauptteilhalter (5) ausgestossen. 



  Fig. 5 zeigt eine Versiegelungsstation im horizontalen Querschnitt. Die in der Transportrinne (9) befindlichen Verschlussteile (21) werden vom Verschlussteilhalter (8a) mittels Vakuum aufgenommen und durch anschliessende Dreh- und Vertikalbewegung zur Positionier- und Benetzungseinheit (12) transportiert. Durch vertikale Bewegung des Verschlussteilhalters (8a) wird das Verschlussteil (21) auf den mit Versiegelungsflüssigkeit (13) getränkten Filz (12a) gedrückt. Dabei wir das Verschlussteil (21) ausgerichtet und mit Versiegelungsflüssigkeit im Überlappungsbereich benetzt. Die Versiegelungsflüssigkeit wird mittels Kapillarwirkung aus dem Behälter (14), welcher mit einem Tropfer (15) und einem Überlauf (16) auf Niveau gehalten wird, in den Filz (12a) gesaugt.

  Eine anschliessende Dreh- und Vertikalbewegung des Verschlussteilhalters (8a) bringt das Verschlussteil (21) zur Verschliess-Station (7) in der  durch Vertikalbewegung des Verschlussteilhalters (8a) das Verschlussteil (21) auf das Hauptteil (22) gedrückt wird. Gleichzeitig wird das Vakuum, das den Verschlussteil (21) im Verschlussteilhalter (8a) hält, weggenommen. Der Verschlussteilhalter (8a) bewegt sich nun durch Dreh- und Vertikalbewegung weiter zur Vibrationsrinne (9), um ein neues Verschlussteil (21) aufzunehmen. 



  Die beschriebene Verschliessmaschine sowie die Versiegelungsstation sind neu und Teil dieser Erfindung. Während üblicherweise pharmazeutische Hartgelatinekapseln im vorverschlossenen Zustand für die Verschliessmaschine angeliefert werden, können erfindungsgemäss der Verschlussteil (21) und der Hauptteil (22) in separaten Vorratsbehältern (10) (1) aufgegeben und unabhängig voneinander zur Schliess-Station (7) transportiert werden. So können auch die Teile unabhängig vor dem Verschliessen benetzt werden. 



  Die folgenden Beispiele erläutern die Erfindung:

  Die Kappe einer aus natürlicher Weizenstärke gemäss den Bedingungen der EP 84 300 940.8 (118 240), Beispiel 8, spritzgegossenen Kapsel mit der Form der Fig. 1 der vorliegenden Erfindung wird mit der Lippe auf einen feinen Filz, welcher mit einer Versiegelungsflüssigkeit bestehend aus 70 Vol.% Wasser und 30 Vol.% Aethanol getränkt ist, 1,5mm tief eingedrückt, so dass die dünne Lippe des Verschlussteiles vollständig benetzt wird. Anschliessend wird dieses Verschlussteil mit dem dazu passenden Hauptteil spannungsfrei zusammengefügt. Nach 10 Minuten lässt sich die Kapsel nicht mehr öffnen.

  It is known to produce compression molded articles from natural starch and hydrophilic materials, such as gelatin, by means of injection molding. Such containers are preferably produced for filling with pharmaceuticals, edibles, chemicals, etc., in particular as pharmaceutical capsules, for the metered administration of medicaments. These containers consist of a main part and a closure part, with at least one of the two parts and generally both parts being provided with matching undercuts to ensure a snap effect and thereby a good closure thereof. Pharmaceutical capsules are of a relatively small dimension. The snap effect is of particular importance because it has to prevent accidental or even deliberate opening of the capsules when the pharmaceutical active ingredients are filled.

  According to the methods known today, depending on the size of the pharmaceutical capsule, the snap closure is achieved by an undercut of high precision of approximately 0.03 mm to 0.15 mm in the main part and / or in the closure part. A smaller undercut causes poor closure; too large causes cracks, especially in the main part.



  Precisely worked undercuts also have various disadvantages. The wall thickness of a pharmaceutical capsule should be kept as thin as possible. As a result, there are different wall thicknesses of the main and the closure part. This results in a different dimensional dynamics of these two parts, which leads to a different geometry of the two parts and to stresses, especially when the air humidity changes.



  This may cause the capsules to explode. Bottled powders or liquids then run out. Difficulties can arise when closing the capsules, particularly in the filling machine.



  The production of undercuts is also technically complex. In particular, slide or jaw tools are necessary, with slide marks then appearing as bumps on the capsule surface. Due to the necessary slides or jaws, the tool has more sliding parts, higher wear, higher pressures or closing forces, higher susceptibility to errors and thus increased downtimes and operating costs. In addition, slides cause a certain degree of tool destabilization. In particular, fewer cavities can be installed per available area, which considerably reduces the output.



  It has now been found that all of the disadvantages mentioned can be remedied if a pressure-molded capsule is used in the filling process which has no undercuts and seals this capsule in the manner according to the invention as described below.



  The definition of the invention is shown in claims 1, 13, 14, 16. Particular embodiments are shown in the dependent claims.



  Starch is understood to mean the naturally occurring vegetable carbohydrate, which mainly consists of amylose and amylopectin. It will e.g. made from potatoes, rice, tapioca, corn, grain such as rye, oats, wheat and other plants. Such starch can be processed into compact moldings of high precision using pressure and elevated temperature. The manufacturing process for pressure molding, in particular for injection molding under pressure and elevated temperature, i.e. the process conditions and the possible additives such as extenders, lubricants, plasticizers and / or dyes are described in European Patent Application No. 84 300 940.8 (Publ. No. 118 240) and also apply to the present invention.



  The term “hydrophilic materials” is to be understood as meaning those hydrophilic materials which are suitable for the production of the containers according to the invention, in particular of pharmaceutical capsules.



  "Hydrophilic materials" are polymeric materials such as gelatin; vegetable proteins such as sunflower, cottonseed, peanut, rapeseed proteins; Blood proteins; Egg proteins; acylated derivatives of the aforementioned proteins; Alginates; Lactose; Gum arabic water-soluble derivatives of cellulose, e.g. Hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methyl cellulose; other water soluble carbohydrates, e.g. Agar Agar; water-soluble synthetic polymers such as anionic or cationic polyacrylates, polyvinylpyrrolidones, vinyl acetate; or networked derivatives of the above connections.



  "Hydrophilic polymeric materials" are also those with so-called enteric properties, i.e. those polymers that dissolve in aqueous media with a slightly basic pH. Such are e.g. Hydroxypropyl methyl cellulose phthalate (HMPCP), polyvinyl acetate phthalate (PVAP), cellulose acetyl phthalate (CAP), cationically modified acrylates and methacrylates e.g. with a tertiary or quaternary amino group, such as the optionally quaternized diethylaminoethyl group; Gelatin phthalates; Gelatin succinate and others Gelatin is preferred.



  The manufacturing processes for pressure molding such hydrophilic materials, especially for injection molding under elevated pressure and temperature, i.e. the process conditions and the possible additives such as extenders, lubricants, plasticizers and / or dyes are described in European Patent Application No. 8 301 643.9 (Pupl. No. 090 600).



  The European patent applications Nos. 84 300 940.8 and 83 301 643.9 details described for the production of such pressure-molded containers, in particular pressure-molded, preferably injection-molded pharmaceutical capsules, also apply to the present invention and are part of the same. In the present invention, pressure-molded containers obtainable in this way, preferably pharmaceutical capsules, are used which are free of undercuts.



  The materials mentioned above can be mentioned as possible extenders, i.e. Starch or another of the "hydrophilic materials", which act as additives as a mixing component or extender. However, extenders are also inorganic fillers such as oxides of magnesium, aluminum, silicon, titanium and others. Concentrations of up to 50% are indicated for extenders, preferably 3-10%, based on the weight of all components forming the container wall.



   Plasticizers are, for example, polyalkylene oxides, such as polyethylene glycols, polypropylene glycols, polyethylene propylene glycols; low molecular weight organic plasticizers such as glycerol, glycerol mono-, di- and triacetate; Propylene glycol, sorbitol, sodium diaethyl sulfosuccinate, triethyl citrate, tributyl citrate and others in a concentration of 0.5-15%, based on the weight of all components.



  Dyes are, for example, known azo dyes or organic or inorganic pigments, or naturally occurring dyes. Inorganic pigments, such as the oxides of iron or titanium known per se, are preferred in a concentration of 0.001-10%, preferably 0.5-5%, based on the weight of all components forming the container wall.



  The containers formed from starch and / or the other hydrophilic materials preferably have a water content of 10-20%, preferably 12-19% and in particular 14-18%, based on the weight of all components forming the container wall.



  The sum of plasticizer and water is preferably at most 25%, preferably at most 20%, based on the weight of all components forming the container wall.



  The term "capsules" used in the following also means containers of any kind according to the definition mentioned above.



  The special feature of the capsules of the present invention in comparison with EP 84 300 940.8 (118 240) and EP 83 301 643.9 (060 900) is that the capsules of the present invention have no undercuts and therefore also no snap closures of any kind. Preferred capsules are those in which the main part and the closure part can be joined together without deformation. Such capsules are new and the subject of the present invention. Sealed capsules of the present invention preferably have practically the same wall thickness at all points, so that stresses due to different dimensional dynamics are avoided.



  Capsules of the present invention are easy to manufacture, fill and seal. However, due to the lack of a snap lock, they can be opened relatively easily or open on their own during further treatment, in particular if the main part and the lock part are joined together with high precision but without deformation. As a rule, the nested surface segments are only 0.5 mm to a maximum of 2 mm high.



  It was therefore surprising to find that the capsules do not open if at least one of the contacting surfaces of the main part or the closure part is brought into contact with a sealing liquid before the final closure.



  This sealing liquid preferably contains water. This is preferably a mixture of water and an alcohol, preferably one with 1-4 C atoms, preferably ethanol, propanols and butanols, in particular ethanol or isopropyl alcohol, preferably ethanol, in a water / alcohol ratio of 95: 5 to 40 : 60, preferably about 80:20 to 60:40, preferably about 70:30.



  Further aqueous sealing agents are, for example, aqueous solutions of sucrose, starch, mono-, oligo- and polysaccharides, glycerin and other polyols, glycol, polyglikols of ethylene glycol and / or propylene glycol, known anionic, cationic or amphoteric surface-active agents, gelatin, polyvinyl alcohols , water-soluble anionic or cationic acrylic polymers in a concentration of 0.5-10 percent by weight, preferably 1-4 percent by weight, based on the total weight of the sealing liquid.



  The above-mentioned water / ethanol mixture is preferred.



  Water alone, for example, causes excessive or imprecise wetting, which results in damage to the contents or the capsule. Due to the high sensitivity of the capsule wall to water, the sealing liquid must allow precise local and quantitative wetting.



  Of course, it takes a certain amount of time for a sealing effect to occur. It was therefore surprising to find that the capsules according to the invention could be further processed and packaged without any opening symptoms.



  Due to the precise local and metered application of the sealing liquid, an exact and liquid-tight seal is achieved. After sealing, the capsule can only be opened by destruction.



  In order to achieve a faster sealing, you can also warm the sealed capsule or the sealing point. Any heat source that does not damage the capsule or its contents can be used, such as convention heat such as heated air; electromagnetic radiation of a suitable frequency, e.g. Microwaves or infrared radiation or ultrasound, the temperature generated being uncritical, provided that the capsule or its contents are not damaged. An acceleration of the sealing by such additional measures is only necessary if necessary. Heating to 30 to 50 ° C is usually sufficient.



  The contents can be solid, pasty or liquid. The filling contents for pharmaceutical capsules are known per se and correspond to the substances which are compatible with the capsule wall and which are usually filled into pharmaceutical hard gelatin capsules.



  By using the capsules according to the invention and sealing them, there are further unexpected advantages in addition to the elimination of the disadvantages mentioned at the beginning. This enables the wall thickness of the capsule to be greatly reduced, since the mechanical stress due to the snap closure is eliminated. This results in a significantly increased opening and dissolving speed of the capsule in the gastric or intestinal juice as well as a saving in material and better volume utilization of the capsule.



  In the figures 1 attached to this description of the invention, the following parts are explained:
 
   1 shows the side view of a capsule according to the invention,
   2 shows the longitudinal section of a capsule according to the invention along line II-II in FIG. 1,
   3 (a) to (u) show different embodiments of the tension-free closure of the main part with the closure part in accordance with note III in FIG. 2,
   4 shows a top view of a filling / sealing machine for the capsules according to the invention,
   Fig. 5 shows the wetting station connected to the filling / sealing machine in section, according to the line V-V in Fig. 4 and
   Fig. 6 shows a perspective illustration of a filling machine, i.e. 4 with a wetting station.
 



   Fig. 1 shows a plan view of a pressure-molded capsule (20), which in principle can have very different external shapes, as is generally known for containers and in particular for capsules. Fig. 1 is only one of the numerous known outer forms.



  FIG. 2 shows the cross section of a capsule (20) according to the invention, the undercut-free closure being specifically indicated with reference to FIG. 3. Closure part (21) and main part (22) are inserted into one another without tension.



  3 (a) to (u) show examples of undercut-free closures, the upper section (22) belonging to the closure part and the lower section (24) to the main part, as shown in FIG. 2.



  Fig. 4 shows the pattern of a filling machine in horizontal cross section with a sealing station. The storage container (1) is connected to a transport channel (2), which leads the main parts to the main part feed station (3) under vibration. In this main part feed station (3), the main parts are pressed with the opening upwards through the plunger (3a) into the main part holder (5). The main part holder (5) is fixed to the turntable (4). The main parts are then cyclically transported to the filling station (6) by rotating the turntable and filled there with a metered amount of a powder (19), a paste or a liquid from a storage container (6a). The filled main part then moves cyclically to the closing station (7).

  In this, the closure parts brought up by the closure part storage container (10) by means of vibration through the transport channel (9) are placed on the main parts by means of the closure part holder (8a) after wetting by the felt (12a). After further transport in cycles, the closed container, in the present case a pharmaceutical capsule, is ejected from the main part holder (5) at the ejection station (11).



  Fig. 5 shows a sealing station in horizontal cross section. The closure parts (21) located in the transport channel (9) are picked up by the closure part holder (8a) by means of a vacuum and transported to the positioning and wetting unit (12) by subsequent rotary and vertical movement. The closure part (21) is pressed onto the felt (12a) soaked with sealing liquid (13) by vertical movement of the closure part holder (8a). We align the closure part (21) and wet it with sealing liquid in the overlap area. The sealing liquid is sucked into the felt (12a) by means of capillary action from the container (14), which is kept at the same level with a dropper (15) and an overflow (16).

  A subsequent rotary and vertical movement of the closure part holder (8a) brings the closure part (21) to the closure station (7), in which the closure part (21) is pressed onto the main part (22) by vertical movement of the closure part holder (8a). At the same time, the vacuum which holds the closure part (21) in the closure part holder (8a) is removed. The closure part holder (8a) now moves further to the vibrating trough (9) by rotating and vertical movement in order to accommodate a new closure part (21).



  The sealing machine described and the sealing station are new and part of this invention. While pharmaceutical hard gelatin capsules are usually delivered in the pre-closed state for the closing machine, the closing part (21) and the main part (22) can be placed in separate storage containers (10) (1) and transported independently of one another to the closing station (7). This means that the parts can be wetted independently before they are closed.



  The following examples illustrate the invention:


 example 1
 



  The cap of a capsule with the shape of FIG. 1 of the present invention, injection molded from natural wheat starch in accordance with the conditions of EP 84 300 940.8 (118 240), Example 8, is placed with the lip on a fine felt which is sealed with a sealing liquid consisting of 70 Vol.% Water and 30 vol.% Ethanol is soaked, 1.5mm deep, so that the thin lip of the closure part is completely wetted. This locking part is then joined together with the matching main part without tension. The capsule can no longer be opened after 10 minutes. The same result is obtained if the capsule is filled beforehand with a solid, pasty or liquid pharmaceutical composition. The closure is liquid-tight (leak-proof).


 Example 2
 



  However, the procedure according to Example 1 is repeated with the addition that it immediately closes the capsule of a heat source as follows: (i) heated air, 35 ° C., 3 minutes, (ii) infrared radiation, 21/2 minutes and (iii) ultrasound , 2 seconds. The capsules can then no longer be opened and are liquid-tight.


 Example 3
 



  The cap (closure part) of a gelatin capsule, produced according to the conditions of EP 83 301 643.9 (060 900), example 2 (B-2), with the shape of FIG. 1 of the present invention, is placed with the lip on a plate which carries a 1.0 mm high liquid film of a mixture of water / ethanol (80:20). The cap is then closed with the main part without deformation.



  After 15 minutes of storage at room temperature, the capsule can no longer be opened. If a heat source according to Example 2 is subsequently used, the shorter welding times given there are obtained.



   In no case could the capsule be opened without destruction after the sealing was completed.


 Example 4
 



  The procedures of Examples 1, 2 and 3 were repeated using sealing fluids of the following compositions:
