Description

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.
Bekannt sind auch Durchdrückverpackungen, die auch als Blisterverpackungen 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.
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.
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.
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 gelöster Form relativ instabil und nicht längere Zeit lagerfähig sind oder die ihre Wirkungen verändern, so dass die flüssige Darreichungsform erst bei Bedarf hergestellt werden muss. Dieses ist aufwendig, zumal mitunter eine genaue Dosierung zwischen dem Medikament und der Flüssigkeit einzuhalten und eine keimfreie Herstellung zu sichern ist.There are already containers for receiving drinks or food known, at the opening of a collar-shaped edge flange is formed. The container closure consists of a film, preferably an aluminum foil, which is releasably and fluid-tightly connected to the edge flange. Regularly, a tab is provided which protrudes beyond the edge flange and which allows removal of the film from the container opening.
Also known are blister packs, which are also referred to as blister packs, for receiving medicines or dietary supplements in the form of tablets, pills or dragees. These packages consist of two superimposed and interconnected foils, wherein in the upper foil convex recesses for receiving a drug or a dietary supplement in tablet form are formed and the flat side of the upper foil is covered by the lower foil. The upper foil is predominantly a plastic foil and the lower foil is an aluminum foil.
When using the drug or dietary supplement, it is forced through the bottom film by pressure on the bulge and taken with a liquid or by drowning a liquid.
A disadvantage of this known blister pack is that its sterility is no longer guaranteed by the contact of the drug with the ambient air or the touch of the hands.
Another disadvantage is that in some situations, for example when traveling is not always a liquid for the intake of the drug is available or otherwise must be carried separately.
Many people, but especially the elderly, are reluctant to take medicines or dietary supplements in solid form, so that a liquid dosage form is generally preferred. Now there are also drugs that are relatively unstable in dissolved form and are not storable for a long time or that change their effects, so that the liquid dosage form must be produced only when needed. This is expensive, especially since sometimes maintain a precise dosage between the drug and the liquid and to ensure a germ-free production.

Aus FR 1 591 549 A sowie US 4,836,370 sind jeweils Verschlüsse für Flüssigkeitsbehälter bekannt, bei denen ein Verschluss für einen Flüssigkeitsbehälter eine Kappe ausbildet, in der Nahrungsergänzungsmittel oder dergleichen anbringbar sind. Durch Druckausübung auf eine den Flüssigkeitsbehälter zugewandte Folie des Verschlusses kann diese zum Zerreißen gebracht werden, so dass das in dem Verschluss angeordnete Nahrungsergänzungsmittel oder dergleichen in den Behälter eintritt.FR 1 591 549 A and US 4,836,370 each have closures known for liquid containers in which a closure for a liquid container forms a cap, attachable in the dietary supplements or the like are. By applying pressure to a liquid container facing film of the closure can tear this be brought so that the arranged in the closure Dietary supplements or the like in the container entry.

Aufgabe der vorliegenden Erfindung ist es deshalb, einen Verschluss für Flüssigkeitsbehälter zu schaffen, der mit einem, an der Öffnung des Flüssigkeitsbehälters angeformten kragenförmigen 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.Object of the present invention is therefore a closure to create for liquid containers, with a, formed on the opening of the liquid container collar-shaped Edge flange detachable, but connected liquid-tight is one and the one germ-free and one against the outside Environment as well as against the container interior tightly closed Storage of a drug or a Dietary supplement until its use together with a liquid and also the preparation of a dispersion or suspension of the drug or dietary supplement and the liquid in the container opening the liquid container allows.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass die obere und untere Folie an ihrem Umfangsrand miteinander verklebt oder verschweißt sind, die untere Folie an ihrem Umfangsrand mit einem kragenförmigen Randflansch des Flüssigkeitsbehälters lösbar verbunden ist und dass am Umfangsrand der oberen Folie und am Umfangsrand der unteren Folie eine über den Randflansch des Flüssigkeitsbehälters hervorstehende Abziehlasche ausgebildet ist.According to the invention, this object is achieved in that the Upper and lower film glued together at their peripheral edge or welded, the lower film at its peripheral edge with a collar-shaped edge flange of the liquid container is detachably connected and that at the peripheral edge the upper foil and at the peripheral edge of the lower foil a over the edge flange of the liquid container protruding Abziehlasche is formed.

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 Nahrungsergänzungsmittel ausgeübten Druckes derart zerreißbar ist, daß das Medikament oder Nahrungsergänzungsmittel 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 Foil glued together only at its peripheral edge or welded. In another embodiment, the plane is Surface of the upper foil and the covering surface of this bottom sheet glued or welded together flat. The upper foil has a lower foil more .... Tear resistance on. The tensile strength difference is the two films according to the invention designed so that the lower Foil as a result of a bulge in the upper foil and about this on the drug or dietary supplement applied pressure is such a tearable that the drug or dietary supplement through the lower foil through can be pressed into the interior of the liquid container and the top sheet is unbreakable by the applied pressure is.

Die obere und untere Folie kann eine Kunststoffolie aus Polymeren, Copolymeren oder Polymer-Blends sein.
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.The upper and lower film may be a plastic film of polymers, copolymers or polymer blends.
Furthermore, the upper film may be thermoplastically deformable. However, the upper film may also be selected from the group consisting of a polyethylene, a polyethylene copolymer, a polyethylene terephthalate, a polypropylene, a polypropylene copolymer and mixtures thereof. On the other hand, the lower film may comprise an aluminum foil, a single or double coated aluminum foil or a brittle polymer foil. Conveniently, the closure also has an over the collar-shaped edge flange protruding Abziehlasche which is formed at the peripheral edge of the upper film or at the peripheral edge of the upper and lower film.

Ein wesentlicher Vorteil der Erfindung besteht darin, daß das Medikament oder das Nahrungsergänzungsmittel 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 Nahrungsergänzungsmittels 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 Nahrungsergänzungsmittel und der im Behälter befindlichen Flüssigkeit ohne großen Arbeitsaufwand möglich.A significant advantage of the invention is that the drug or dietary supplement and the liquid required for ingestion is contained in a single package, so that the separate entrainment or procurement of revenue liquid is eliminated. The germ-free and liquid-tight arrangement of the drug or dietary supplement within the container closure a separate storage of both components is achieved until use, whereby a longer shelf life is achievable.
The pushing of the drug or the food supplement through the lower film into the interior of the liquid container with a closed container advantageously allows the germ-free production of a dispersion or suspension, which is generally preferred as a liquid dosage form by consumers. Finally, by the invention, a precise dosage of drug or dietary supplement and the liquid in the container without much work is possible.

Die Erfindung soll nachstehend anhand der dazugehörigen Zeichnung näher erläutert werden. Es zeigen:

  • Fig. 1 - eine Vorderansicht des Flüssigkeitsbehälters mit dem erfindungsgemäßen Verschluß;
  • Fig. 2 - den oberen Teil des Flüssigkeitsbehälters mit dem erfindungsgemäßen Verschluß und dem Medikament oder Nahrungsergänzungsmittel in Tablettenform im Schnitt;
  • Fig. 3 - den oberen Teil des Flüssigkeitsbehälters nach Fig. 2 mit dem durch die untere Folie hindurchgedrückten Medikament oder Nahrungsergänzungsmittel in Tablettenform im Schnitt.
    • The invention will be explained below with reference to the accompanying drawings. Show it:
  • Fig. 1 - a front view of the liquid container with the closure according to the invention;
  • Figure 2 - the upper part of the liquid container with the closure according to the invention and the drug or dietary supplement in tablet form in section.
  • Fig. 3 - the upper part of the liquid container of Fig. 2 with the pushed through the lower film drug or dietary supplement in tablet form in section.

    • 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.As is apparent from FIGS. 2 and 3, the invention consists Closure of two superposed foils 2 and 4, between which a cavity for receiving a drug or dietary supplement 3 is formed. This Cavity is formed by a centrally arranged, convex, cup-shaped Bulge 8 in the upper slide 2 and through the the level side of the upper film 2 covering lower film 4 is formed. The thus formed closure is with a, at the Opening of the liquid container 6 integrally formed collar-shaped Edge flange 7 connected liquid-tight. Furthermore, the flat surface of the upper film 2 and the surface covering this the lower film 4 at least in part by gluing or welding together. After a Embodiment of the closure is the upper and lower Foil 2 and 4 glued together only at their peripheral edge or welded. This embodiment is given priority to Liquid container with a small width of the container opening used. For container openings with a larger one Width is according to another embodiment, the flat surface the upper sheet 2 and the covering surface of the lower Foil 4 glued together flat or welded.

    Der Verschluss weist auch eine über den Randflansch 7 hervorstehende Abziehlasche 5 auf, die am Umfangsrand der oberen Folie 2 und am Umfangsrand der unteren Folie 4 ausgebildet ist.The closure also has a protruding over the edge flange 7 Abziehlasche 5, which at the peripheral edge of the upper Foil 2 and formed on the peripheral edge of the lower film 4 is.

    Diese Ausführungsvariante ermöglicht, den Flüssigkeitsbehälter 6 während der Einnahme der zuvor hergestellten Dispersion oder Suspension aus dem Medikament oder dem Nahrungsergänzungsmittel 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.This embodiment allows the liquid container 6 while taking the previously prepared dispersion or suspension of the drug or dietary supplement 3 and the liquid 1, for example water, essentially keep it closed, which is hygienic Reasons is recommended. Here, in the liquid container 6 located dispersion or suspension, for example be absorbed by a drinking straw, the in the crack is introduced 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.When the pull tab 5 at the peripheral edge of the upper and the lower Foil 2 and 4 is formed, both foils together deducted from the edge flange 7 and thus the liquid container 6 are fully opened. To make this possible is the upper and the lower film 2 and 4 with each other welded or unsolvable glued and the lower Foil 4 releasably bonded to the edge flange 7.

    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 Nahrungsergänzungsmittel 3 ausgeübten Druckes nicht nur einreißt, sondern so aufreißt, daß das Medikament oder Nahrungsergänzungsmittel 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.
    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.
    Die obere Folie 2 ist thermoplastisch verformbar. Nach einer anderen Ausführungsvariante ist die obere Folie 2 aus der Gruppe ausgewählt, bestehend aus einem Polyethylen, einem Polyethylen-Mischpolymerisat, einem Polyethylenterephthalat, einem Polypropylen, einem Polypropylen-Mischpolymerisat und Gemischen davon.
    Nach einer weiteren Ausführungsvariante ist die untere Folie 4 eine Aluminiumfolie, eine ein- oder beidseitig beschichtete Aluminiumfolie oder eine spröde Polymerfolie.
    In Fig. 2 und 3 ist das Medikament oder Nahrungsergänzungsmittel 3 in Tablettenform dargestellt. Die Tablettenform ist für das Durchdrücken durch die untere Folie 4 sehr vorteilhaft. Das Medikament oder Nahrungsergänzungsmittel 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.    The upper film 2 has a greater tensile strength than the lower film 4. The tensile strength difference of the two films 2 and 4 is designed so that the lower film 4 not only tears as a result of a pressure exerted on the bulge 8 in the upper film 2 and on the drug or dietary supplement 3 pressure, but so tears that the Drug or dietary supplement 3 can be pushed through the lower film 4 into the interior of the liquid container 6. Due to the applied pressure, the bulge 8 is merely bent or buckled, wherein the upper foil 2 does not rupture.
    The tear strength of the films 2 and 4 is to be interpreted depending on the film material used, on the clear width of the container opening and on the film thickness. The thickness of the films is always greater than 0.015 mm.
    The films 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, the upper and the lower film 2 and 4 is a plastic film of polymers, copolymers or polymer blends, such as PE, LDPE, MDPE, HDPE, LLDPE, PET and PP.
    The upper film 2 is thermoplastically deformable. According to another embodiment variant, the upper film 2 is selected from the group consisting of a polyethylene, a polyethylene copolymer, a polyethylene terephthalate, a polypropylene, a polypropylene copolymer and mixtures thereof.
    According to a further embodiment, the lower film 4 is an aluminum foil, a single or double coated aluminum foil or a brittle polymer foil.
    In Fig. 2 and 3, the drug or dietary supplement 3 is shown in tablet form. The tablet form is very advantageous for pushing through the lower foil 4. The drug or dietary supplement 3 may also be present in powdered or liquid form.
    In one embodiment, the clear width of the container opening is 20 mm and the width of the edge flange 3.5 mm. The upper film 2 is made 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 film 2 and 4 is welded or sealed together at its peripheral edge and the lower film 4 with the edge flange 7 releasably bonded. 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 is the container opening 70 mm and the width of the edge flange 6 mm. The upper film 2 is a polypropylene film having a Thickness of 0.2 mm and the lower film 4 a plastic coated on both sides Aluminum foil with a thickness of 0.1 mm. The flat surface of the upper film 2 and this covering Surface of the lower film 4 is flat with each other solvable bonded. 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 handling of the closure according to the invention takes place following way:

    Es wird Druck, beispielsweise mit einem Finger auf die Ausbuchtung 8 in der oberen Folie 2 ausgeübt und das Medikament oder Nahrungsergänzungsmittel 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 Nahrungsergänzungsmittel 3 und der Flüssigkeit 1 hergestellt.
    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 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.    It is pressure, for example, with a finger exerted on the bulge 8 in the upper sheet 2 and the medicament or dietary supplement 3 is pushed through the lower film 4, whereby it falls into the liquid container 1 located in the liquid 1, which in Fig. 3 by the Arrow A is shown. By shaking the liquid container 6, the desired dispersion or suspension of the drug or dietary supplement 3 and the liquid 1 is prepared.
    By means of trained on the peripheral edge of the upper and lower film 2 and 4 Abziehlasche 5 both films 2 and 4 are withdrawn together and simultaneously from the edge flange 7 (see Fig. 3, arrow B) and the liquid container 6 thereby fully opened. If the pull-tab 5 is formed only 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. In this case, the dispersion or suspension can be absorbed 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 Nahrungsergänzungsmittel 3 durch die untere Folie 4 hindurchgedrückt und dann zusammen mit der Flüssigkeit 1 oder durch Nachtrinken der Flüssigkeit 1 eingenommen.It goes without saying that the user is free to do so Pressing the drug or dietary supplement 3 through the lower film 4 and the preparation of a dispersion or suspension. In this case, the upper and lower film 2 and 4 pulled together from the edge flange 7, the drug or dietary supplement 3 by the pressed lower foil 4 and then together with the Liquid 1 or taken by Nachtrinken the liquid 1.
