Abstract

The invention relates to a seal for containers of liquids. The inventive seal is connected to an edge flange (7) which is moulded onto the opening of the container (6), in such a way that the connection is liquid tight. The seal consists of two films (2,4) located one above the other. A hollow space for accommodating a medicament or a nutritional supplement (3) is provided between the two films. Said hollow space is formed by a central, convex, cup-shaped rounded section (8) in the top film (2) and by the bottom film (4) covering the flat side of the top film (2). The flat surface of the top film (2) and the surface of the bottom film (4) covering the same are at least partially joined by sticking or welding. The top film (2) is more resistant to tearing than the bottom film (4). The difference in tear resistance between the two films (2, 4) is such that when pressure is applied to the rounded section (8) and hereby to the medicament or nutritional supplement (3), the bottom film (4) can be broken whilst the top film cannot.

Description

Verschluß für FlüssigkeitsbehälterClosure for liquid containers
Es sind bereits Behälter zur Aufnahme von Getränken oder Nahrungsmitteln bekannt, an deren Öffnung ein kragenförmiger Randflansch angeformt ist. Der Behälterverschluß besteht dabei aus einer Folie, vorzugsweise einer Aluminiumfolie, die mit dem Randflansch lösbar und flüssigkeitsdicht verbunden ist. Regelmäßig ist auch eine Lasche vorgesehen, die über den Randflansch hervorsteht und die ein Abziehen der Folie von der Behälteröffnung ermöglicht.Containers for holding beverages or food are already known, at the opening of which a collar-shaped edge flange is molded. The container closure consists of a film, preferably an aluminum film, which is detachably and liquid-tightly connected to the edge flange. A tab is also regularly provided, which protrudes beyond the edge flange and which enables the film to be pulled off the container opening.
Bekannt sind auch Durchdrückverpackungen, die auch als Bli- sterverpackungen bezeichnet werden, zur Aufnahme von Medikamenten oder Nahrungsergänzungsmitteln in Form von Tabletten, Pillen oder Dragees. Diese Verpackungen bestehen aus zwei übereinander angeordneten und miteinander verbundenen Folien, wobei in der oberen Folie konvexe Ausbuchtungen zur Aufnahme eines Medikaments oder eines Nahrungsergänzungsmittels in Tablettenform ausgebildet sind und die ebene Seite der oberen Folie durch die untere Folie abgedeckt ist. Dabei ist die obere Folie vorwiegend eine Kunststoffolie und die untere Folie eine Aluminiumfolie.Press-through packaging, which is also known as blister packaging, for receiving medicaments or food supplements in the form of tablets, pills or dragees is also known. These packages consist of two films arranged one above the other and connected to one another, convex bulges for receiving a medicament or a food supplement in tablet form are formed in the upper film and the flat side of the upper film is covered by the lower film. The upper film is primarily a plastic film and the lower film is an aluminum film.
Beim Gebrauch des Medikaments oder des Nahrungsergänzungsmittels wird dieses durch Druck auf die Ausbuchtung durch die untere Folie hindurchgedrückt und zusammen mit einer Flüssigkeit oder durch Nachtrinken einer Flüssigkeit eingenommen. Ein Nachteil dieser bekannten Durchdrückverpackung besteht darin, daß durch den Kontakt des Medikaments mit der Umgebungsluft oder der Berührung mit den Händen dessen Keimfreiheit nicht mehr gewährleistet ist.When using the medicament or the nutritional supplement, it is pressed through the lower film by pressure on the bulge and taken together with a liquid or by drinking a liquid afterwards. A disadvantage of this known push-through packaging is that the sterility is no longer guaranteed by the contact of the medication with the ambient air or the contact with the hands.
Nachteilig ist auch, daß in manchen Situationen, beispielsweise bei Reisen nicht immer eine Flüssigkeit für die Einnahme des Medikaments zur Verfügung steht oder anderenfalls separat mitgeführt werden muß.It is also disadvantageous that in some situations, for example when traveling, a liquid is not always available for taking the medication, or else it must be carried separately.
Viele Menschen, insbesondere aber alte Menschen, nehmen Medikamente oder Nahrungsergänzungsmittel in fester Form nur ungern ein, so daß eine flüssige Darreichungsform allgemein bevorzugt wird. Nun gibt es auch Medikamente, die in gelösterMany people, especially old people, are reluctant to take medication or nutritional supplements in solid form, so that a liquid dosage form is generally preferred.

This is complex, especially since an exact dosage between the medication and the liquid must sometimes be observed and a germ-free production must be ensured.
Aufgabe der vorliegenden Erfindung ist es deshalb, einen Verschluß für Flüssigkeitsbehälter zu schaffen, der mit einem, an der Öffnung des Flüssigkeitsbehälters angeformten kragenförmi- gen Randflansch lösbar aber flüssigkeitsdicht verbunden ist und der eine keimfreie und eine gegenüber der äußeren Umgebung als auch gegenüber dem Behälterinnenraum dicht verschlossene Aufbewahrung eines Medikaments oder eines Nahrungsergänzungsmittels bis zu seinem Gebrauch zusammen mit einer Flüssigkeit und der auch die Herstellung einer Dispersion oder Suspension aus dem Medikament bzw. Nahrungsergänzungsmittel und der im Behälter befindlichen Flüssigkeit vor dem Öffnen des Flüssigkeitsbehälters ermöglicht.The object of the present invention is therefore to create a closure for liquid containers which is detachably but liquid-tightly connected to a collar-shaped edge flange formed on the opening of the liquid container and which is germ-free and sealed against the external environment and also against the container interior sealed storage of a medicament or nutritional supplement until it is used together with a liquid and which also enables the preparation of a dispersion or suspension of the medicament or nutritional supplement and the liquid in the container before opening the liquid container.
Erfindungsgemäß wird diese Aufgabe durch zwei übereinander angeordnete Folien gelöst, zwischen denen ein Hohlraum zur Aufnahme des Medikaments oder Nahrungsergänzungsmittels ausgebildet ist. Dabei wird dieser Hohlraum durch eine zentrisch angeordnete, konvexe, napfförmige Ausbuchtung in der oberen Folie und die die ebene Seite der oberen Folie abdeckende untere Folie gebildet. In weiterer Ausbildung der Erfindung ist die ebene Fläche der oberen Folie und die diese abdeckende Fläche der unteren Folie mindestens zum Teil durch Verkleben oder Verschweißen miteinander verbunden.According to the invention, this object is achieved by means of two foils arranged one above the other, between which a cavity is formed for receiving the medicament or food supplement. This cavity is formed by a centrally arranged, convex, cup-shaped bulge in the upper film and the lower film covering the flat side of the upper film. In a further embodiment of the invention, the flat surface of the upper film and the surface of the lower film covering this are at least partially connected to one another by gluing or welding.
Nach einer ersten Ausführungsform ist die obere und die untere Folie nur an ihrem Umfangsrand miteinander verklebt oder verschweißt. Bei einer anderen Ausführungsform ist die ebene Fläche der oberen Folie und die diese abdeckende Fläche der unteren Folie flächig miteinander verklebt oder verschweißt. Die obere Folie weist gegenüber der unteren Folie eine größere Reißfestigkeit auf. Dabei ist die Reißfestigkeitsdifferenz der beiden Folien nach der Erfindung so ausgelegt, daß die untere Folie infolge eines auf die Ausbuchtung in der oberen Folie und über diese auf das Medikament oder Nahrungserganzungsmittel ausgeübten Druckes derart zerreißbar ist, daß das Medikament oder Nahrungserganzungsmittel durch die untere Folie hindurch in das Innere des Flüssigkeitsbehälters drückbar ist und die obere Folie durch den ausgeübten Druck unzerreißbar ist.According to a first embodiment, the upper and the lower film are glued or welded to one another only at their peripheral edge. In another embodiment, the flat surface of the upper film and the surface of the lower film covering it are adhesively bonded or welded to one another. The upper film has a larger one than the lower film Tensile strength. The difference in tensile strength of the two films according to the invention is designed such that the lower film can be torn as a result of a pressure exerted on the bulge in the upper film and, via this, on the medicament or food supplement, such that the medicament or food supplement passes through the lower film can be pressed into the interior of the liquid container and the upper film cannot be torn by the pressure exerted.
Die obere und untere Folie kann eine Kunststoffolie aus Polymeren, Copoly eren oder Polymer-Blends sein.The upper and lower film can be a plastic film made of polymers, copoly mers or polymer blends.
Weiterhin kann die obere Folie thermoplastisch verformbar sein. Die obere Folie kann aber auch aus der Gruppe ausgewählt sein, bestehend aus einem Polyethylen, einem Polyethylen- Mischpolymerisat, einem Polyethylenterephthalat , einem Polypropylen, einem Polypropylen-Mischpolymerisat und Gemischen davon. Hingegen kann die untere Folie eine Aluminiumfolie, eine ein- oder beidseitig beschichtete Aluminiumfolie oder eine spröde Polymerfolie umfassen. Zweckmäßigerweise verfügt der Verschluß auch über eine über den kragenförmigen Randflansch hervorstehende Abziehlasche, die am Umfangsrand der oberen Folie oder am Umfangsrand der oberen und der unteren Folie ausgebildet ist.Furthermore, the upper film can be thermoplastic. The top film can also be selected from the group consisting of a polyethylene, a polyethylene copolymer, a polyethylene terephthalate, a polypropylene, a polypropylene copolymer and mixtures thereof. In contrast, the lower film can comprise an aluminum film, an aluminum film coated on one or both sides or a brittle polymer film. The closure also expediently has a pull tab which projects beyond the collar-shaped edge flange and is formed on the peripheral edge of the upper film or on the peripheral edge of the upper and lower films.
Ein wesentlicher Vorteil der Erfindung besteht darin, daß das Medikament oder das Nahrungserganzungsmittel und die zur Einnahme benötigte Flüssigkeit in einer einzigen Verpackung enthalten ist, so daß die separate Mitführung oder Beschaffung von Einnahmeflüssigkeit entfällt. Durch die keimfreie und flüssigkeitsdichte Anordnung des Medikaments oder des Nahrungsergänzungsmittels innerhalb des Behälterverschlusses wird eine getrennte Aufbewahrung beider Komponenten bis zum Gebrauch erzielt, wodurch eine längere Lagerfähigkeit erreichbar ist. Das Durchdrücken des Medikamentes bzw. des Nahrungsergänzungs- mittels durch die untere Folie in das Innere des Flüssigkeitsbehälters bei geschlossenem Behälter ermöglicht in vorteilhafter Weise die keimfreie Herstellung einer Dispersion oder Suspension, die als flüssige Darreichungsform von den Verbrauchern allgemein bevorzugt wird. Letzlich ist durch die Erfindung auch eine genaue Dosierung von Medikament oder Nahrungserganzungsmittel und der im Behälter befindlichen Flüssigkeit ohne großen Arbeitsaufwand möglich.An important advantage of the invention is that the medicament or the food supplement and the liquid required for ingestion are contained in a single package, so that the separate carrying or procurement of ingestion liquid is not necessary. Due to the aseptic and liquid-tight arrangement of the medication or the nutritional supplement within the container closure, separate storage of both components is achieved until use, so that a longer shelf life can be achieved. Pushing through the medication or nutritional supplement by means of the lower film into the interior of the liquid container when the container is closed advantageously enables the aseptic production of a dispersion or suspension, which is generally preferred by consumers as a liquid administration form. Ultimately, the invention also enables precise dosing of medication or food supplements and the liquid in the container without great effort.

Wie aus Fig. 2 und 3 ersichtlich ist, besteht der erfindungsgemäße Verschluß aus zwei übereinander angeordneten Folien 2 und 4, zwischen denen ein Hohlraum zur Aufnahme eines Medikaments oder Nahrungsergänzungsmittels 3 ausgebildet ist. Dieser Hohlraum wird durch eine zentrisch angeordnete, konvexe, napfförmige Ausbuchtung 8 in der oberen Folie 2 und durch die die ebene Seite der oberen Folie 2 abdeckende untere Folie 4 gebildet. Der so ausgebildete Verschluß ist mit einem, an der Öffnung des Flüssigkeitsbehälters 6 angeformten kragenförmigen Randflansch 7 flüssigkeitsdicht verbunden. Weiterhin ist die ebene Fläche der oberen Folie 2 und die diese abdeckende Fläche der unteren Folie 4 mindestens zu einem Teil durch Verkleben oder Verschweißen miteinander verbunden. Nach einer Ausführungsform des Verschlusses ist die obere und untere Folie 2 und 4 nur an ihrem Umfangsrand miteinander verklebt oder verschweißt. Diese Ausführungsform wird vorrangig für Flüssigkeitsbehälter mit einer geringen Weite der Behälteröffnung verwendet. Für Behälteröffnungen mit einer größeren Weite ist nach einer anderen Ausführungsform die ebene Fläche der oberen Folie 2 und die diese abdeckende Fläche der unteren folie 4 flächig miteinander verklebt oder verschweißt. Der Verschluß weist auch eine über den Randflansch 7 hervorstehende Abziehlasche 5 auf, die am Umfangsrand der oberen Folie 2 oder am Umfangsrand der oberen und der unteren Folie 2 und 4 ausgebildet ist. Durch die Ausbildung der AbziehlascheAs can be seen from FIGS. 2 and 3, the closure according to the invention consists of two films 2 and 4 arranged one above the other, between which a cavity is formed for receiving a medicament or nutritional supplement 3. This cavity is formed by a centrally arranged, convex, cup-shaped bulge 8 in the upper film 2 and by the lower film 4 covering the flat side of the upper film 2. The closure formed in this way is connected in a liquid-tight manner to a collar-shaped edge flange 7 formed on the opening of the liquid container 6. Furthermore, the flat surface of the upper film 2 and the surface of the lower film 4 covering this are connected to one another at least in part by gluing or welding. According to one embodiment of the closure, the upper and lower Sheets 2 and 4 are only glued or welded together at their peripheral edge. This embodiment is primarily used for liquid containers with a small width of the container opening. For container openings with a larger width, according to another embodiment, the flat surface of the upper film 2 and the surface of the lower film 4 covering this are glued or welded to one another over the surface. The closure also has a pull tab 5 projecting over the edge flange 7, which is formed on the peripheral edge of the upper film 2 or on the peripheral edge of the upper and lower films 2 and 4. By forming the pull tab
5 an der oberen Folie 2 wird erreicht, daß nur diese vom Randflansch 7 abgezogen werden kann und die untere Folie 4 mit dem Randflansch 7 fest verbunden bleibt. Dazu ist die obere und die untere Folie 2 und 4 lösbar miteinander verklebt und die untere Folie 4 mit dem Randflansch 7 verschweißt oder unlösbar verklebt.5 on the upper film 2 is achieved that only this can be removed from the edge flange 7 and the lower film 4 remains firmly connected to the edge flange 7. For this purpose, the upper and lower foils 2 and 4 are detachably glued to one another and the lower foil 4 is welded to the edge flange 7 or glued inseparably.
Diese Ausführungsvariante ermöglicht, den FlüssigkeitsbehälterThis variant enables the liquid container
6 während der Einnahme der zuvor hergestellten Dispersion oder Suspension aus dem Medikament oder dem Nahrungserganzungsmittel 3 und der Flüssigkeit 1, beispielsweise Wasser im wesentlichen verschlossen zu halten, was aus hygienischen Gründen empfehlenswert ist. Hierbei kann die im Flüssigkeitsbehälter 6 befindliche Dispersion oder Suspension zum Beispiel mittels eines Trinkhalmes aufgenommen werden, der in den Riß in der unteren Folie 4 eingeführt wird.6 to keep essentially closed while taking the previously prepared dispersion or suspension of the medicament or the food supplement 3 and the liquid 1, for example water, which is recommended for hygienic reasons. Here, the dispersion or suspension in the liquid container 6 can be absorbed, for example, by means of a drinking straw which is introduced into the crack in the lower film 4.
Wenn die Abziehlasche 5 am Umfangsrand der oberen und der unteren Folie 2 und 4 ausgebildet ist, können beide Folien gemeinsam vom Randflansch 7 abgezogen und damit der Flüssigkeitsbehälter 6 vollständig geöffnet werden. Um dieses zu ermöglichen, ist die obere und die untere Folie 2 und 4 miteinander verschweißt oder unlösbar verklebt und die untere Folie 4 mit dem Randflansch 7 lösbar verklebt. Die obere Folie 2 weist gegenüber der unteren Folie 4 eine größere Reißfestigkeit auf. Die Reißfestigkeitsdifferenz der beiden Folien 2 und 4 ist dabei so ausgelegt, daß die untere Folie 4 infolge eines auf die Ausbuchtung 8 in der oberen Folie 2 und über diese auf das Medikament oder Nahrungserganzungsmittel 3 ausgeübten Druckes nicht nur einreißt, sondern so aufreißt, daß das Medikament oder NahrungserganzungsmittelIf the pull tab 5 is formed on the circumferential edge of the upper and lower foils 2 and 4, both foils can be pulled off together from the edge flange 7 and the liquid container 6 can thus be opened completely. To make this possible, the upper and lower foils 2 and 4 are welded to one another or permanently bonded and the lower foil 4 is releasably glued to the edge flange 7. The upper film 2 has a greater tear resistance than the lower film 4. The difference in tensile strength of the Both foils 2 and 4 are designed such that the lower foil 4 not only tears as a result of a pressure exerted on the bulge 8 in the upper foil 2 and via this on the medicament or food supplement 3, but also tears open such that the medicament or food supplement
3 durch die untere Folie 4 hindurch in das Innere des Flüssigkeitsbehälters 6 gedrückt werden kann. Durch den ausgeübten Druck wird die Ausbuchtung 8 lediglich durchgebogen oder geknautscht, wobei die obere Folie 2 nicht zerreißt.3 can be pressed through the lower film 4 into the interior of the liquid container 6. The bulge 8 is merely bent or crumpled by the pressure exerted, the upper film 2 not tearing.
Die Reißfestigkeit der Folien 2 und 4 ist in Abhängigkeit von dem verwendeten Folienmaterial, von der lichten Weite der Behälteröffnung und von der Foliendicke auszulegen. Die Dicke der Folien ist aber stets größer als 0,015 mm. Die Folien 2 und 4 bestehen aus einem lebensmitteltechnisch unbedenklichen Material, beispielsweise gemäß der US-Vorschrift FDA-Regulations 21 CFR, 177.1520 oder gemäß der europäischen Richtlinie 90/128/EWG, Anlage 2, Abschnitt A. Gemäß einer Ausführungsvariante ist die obere und die untere Folie 2 und 4 eine Kunststoffolie aus Polymeren, Copolymeren oder Polymer-Blends, wie beispielsweise PE, LDPE, MDPE, HDPE, LLDPE, PET und PP.The tensile strength of films 2 and 4 is to be designed depending on the film material used, the inside width of the container opening and the film thickness. However, the thickness of the foils is always greater than 0.015 mm. The foils 2 and 4 consist of a food-safe material, for example according to the US regulation FDA Regulations 21 CFR, 177.1520 or according to the European Directive 90/128 / EEC, Appendix 2, Section A. According to one embodiment variant, the upper and the lower film 2 and 4 a plastic film made of polymers, copolymers or polymer blends, such as PE, LDPE, MDPE, HDPE, LLDPE, PET and PP.

In Fig. 2 und 3 ist das Medikament oder Nahrungserganzungsmittel 3 in Tablettenform dargestellt. Die Tablettenform ist für das Durchdrücken durch die untere Folie 4 sehr vorteilhaft. Das Medikament oder Nahrungserganzungsmittel 3 kann aber auch in pulverförmiger oder flüssiger Form vorliegen. Bei einem Ausführungsbeispiel beträgt die lichte Weite der Behälteröffnung 20 mm und die Breite des Randflansches 3,5 mm. Die obere Folie 2 besteht aus Polyethylen mit einer Dicke von 0,15 mm und die untere Folie 4 aus Aluminium mit einer Dicke von 0,075 mm. Die obere und untere Folie 2 und 4 ist an ihrem Umfangsrand miteinander verschweißt oder versiegelt und die untere Folie 4 mit dem Randflansch 7 lösbar verklebt. Die Abziehlasche 5 ist am Umfangsrand der oberen und der unteren Folie 2 und 4 ausgebildet.2 and 3, the medicament or food supplement 3 is shown in tablet form. The tablet form is very advantageous for pushing through the lower film 4. However, the medicament or food supplement 3 can also be in powder or liquid form. In one embodiment, the inside width is Container opening 20 mm and the width of the edge flange 3.5 mm. The upper film 2 consists of polyethylene with a thickness of 0.15 mm and the lower film 4 made of aluminum with a thickness of 0.075 mm. The upper and lower films 2 and 4 are welded or sealed to one another at their peripheral edge and the lower film 4 is releasably glued to the edge flange 7. The pull tab 5 is formed on the peripheral edge of the upper and lower foils 2 and 4.
Bei einem anderen Ausführungsbeispiel beträgt die lichte Weite der Behälteröffnung 70 mm und die Breite des Randflansches 6 mm. Die obere Folie 2 ist eine Polypropylen-Folie mit einer Dicke von 0,2 mm und die untere Folie 4 eine beidseitig kunststoffbeschichtete Aluminiumfolie mit einer Dicke von 0,1 mm. Die ebene Fläche der oberen Folie 2 und die diese abdeckende Fläche der unteren Folie 4 ist flächig miteinander lösbar verklebt. Die untere Folie 4 ist mit dem Randflansch 7 verschweißt und die Abziehlasche 5 an der oberen Folie 2 ausgebildet.In another embodiment, the inside width of the container opening is 70 mm and the width of the edge flange is 6 mm. The upper film 2 is a polypropylene film with a thickness of 0.2 mm and the lower film 4 is a double-sided plastic-coated aluminum film with a thickness of 0.1 mm. The flat surface of the upper film 2 and the surface of the lower film 4 covering it is adhesively bonded to one another in a planar manner. The lower film 4 is welded to the edge flange 7 and the pull tab 5 is formed on the upper film 2.
Die Handhabung des erfindungsgemäßen Verschlusses erfolgt auf folgende Weise:The closure according to the invention is handled in the following way:
Es wird Druck, beispielsweise mit einem Finger auf die Ausbuchtung 8 in der oberen Folie 2 ausgeübt und das Medikament oder Nahrungserganzungsmittel 3 durch die untere Folie 4 hindurchgedrückt, wodurch es in die im Flüssigkeitsbehälter 6 befindliche Flüssigkeit 1 fällt, was in Fig. 3 durch den Pfeil A dargestellt ist. Durch Schütteln des Flüssigkeitsbehälters 6 wird die gewünschte Dispersion oder Suspension aus dem Medikament oder Nahrungserganzungsmittel 3 und der Flüssigkeit 1 hergestellt.Pressure is exerted, for example with a finger, on the bulge 8 in the upper film 2 and the medicament or food supplement 3 is pressed through the lower film 4, as a result of which it falls into the liquid 1 in the liquid container 6, which in FIG Arrow A is shown. The desired dispersion or suspension of the medicament or food supplement 3 and the liquid 1 is produced by shaking the liquid container 6.
Mittels der am Umfangsrand der oberen und der unteren Folie 2 und 4 ausgebildeten Abziehlasche 5 werden beide Folien 2 und 4 gemeinsam und gleichzeitig vom Randflansch 7 abgezogen (siehe Fig. 3, Pfeil B) und der Flüssigkeitsbehälter 6 dadurch 8 vollständig geöffnet. Ist die Abziehlasche 5 nur an der oberen Folie 2 ausgebildet, so wird nur die obere Folie 2 abgezogen und die untere Folie 4 bleibt mit dem Randflansch 7 fest verbunden. Hierbei kann die Dispersion oder Suspension mittels eines Trinkhalmes aufgenommen werden.By means of the pull tab 5 formed on the peripheral edge of the upper and lower foils 2 and 4, both foils 2 and 4 are pulled off together and simultaneously from the edge flange 7 (see FIG. 3, arrow B) and the liquid container 6 thereby 8 fully open. If the pull tab 5 is only formed on the upper film 2, only the upper film 2 is pulled off and the lower film 4 remains firmly connected to the edge flange 7. The dispersion or suspension can be taken up by means of a drinking straw.
Es bleibt dem Benutzer selbstverständlich unbenommen, auf das Durchdrücken des Medikaments oder Nahrungsergänzungsmittels 3 durch die untere Folie 4 und die Herstellung einer Dispersion oder Suspension zu verzichten. In diesem Falle wird die obere und untere Folie 2 und 4 gemeinsam vom Randflansch 7 abgezogen, das Medikament oder Nahrungserganzungsmittel 3 durch die untere Folie 4 hindurchgedrückt und dann zusammen mit der Flüssigkeit 1 oder durch Nachtrinken der Flüssigkeit 1 eingenommen. The user is, of course, at liberty to forego pushing the medication or food supplement 3 through the lower film 4 and producing a dispersion or suspension. In this case, the upper and lower films 2 and 4 are pulled off together from the edge flange 7, the medicament or food supplement 3 is pressed through the lower film 4 and then taken together with the liquid 1 or by drinking the liquid 1 again.
