Zur Entnahme einer Knopfzelle (4) braucht diese nur von außen durch die leicht aufreißbare Aluminiumfolie durchgedrückt zu werden. Bei besonders zuverlässigen Verpackungen zum Versand in Gebiete mit extrem feuchtem oder trockenen Klima kann sowohl der Napffolie als auch der Verschlußfolie ein mehrschichtiges Kunststoff/Metall-Verbundmaterial zugrundeliegen.A packaging (1) intended especially for zinc / air hearing aid batteries of the button cell type, which is impermeable to air and water vapor, is partly made of a tear-resistant, preferably transparent film (2) made of PVC or polyvinylidene chloride with cup-shaped features (3) for receiving the button cells and the other part of a sealing film (5) made of aluminum and sealed onto this surface. To remove a button cell (4), it only needs to be pushed through from the outside through the easily tearable aluminum foil. In the case of particularly reliable packaging for shipping to areas with an extremely humid or dry climate, both the cup film and the sealing film can be based on a multi-layer plastic / metal composite material.

Description

Die Erfindung betrifft ein Verpackungselement zur Lagerung von galvanischen Luftsauerstoffelementen unter Luftabschluß bis zu ihrer Inbetriebnahme. Un­ter den Luftsauerstoffelementen bilden insbesondere Hörgerätebatterien vom Knopfzellentyp das bevorzugte Anwendungsgebiet der Erfindung.The invention relates to a packaging element for storing galvanic atmospheric oxygen elements in the absence of air until they are put into operation. Among the atmospheric oxygen elements, in particular hearing aid batteries of the button cell type form the preferred field of application of the invention.

Die handelsüblichen Knopfzellen des wiederaufladbaren Ni/Cd-Systems oder Knopfzellen der Primärsystem Ag₂O/Zn und HgO/Zn gelangen meist in relativ aufwendigen Verpackungen an den Endverbraucher. Beispiele für solche Behältnisse lassen sich der US-PS 3,414,161 oder der DE-AS 25 45 049 ent­nehmen. Alle ähneln sich in ihrem grundlegenden Aufbau aus zwei runden Ge­häuseschalen aus Plastik, von denen die eine durch entsprechende Segmentie­rung kreisförmig angeordnete Fächer für die Aufnahme der Knopfzellen be­sitzt, und welche beide so ineinandergefügt sind, daß die eine Gehäuseschale gegen die festgehaltene andere Schale gedreht werden kann. Dabei werden die Knopfzellen der Reihe nach mit einem Ausgabeauslaß an der nichtsegmen­tierten, glatten Gehäuseschale zur Deckung gebracht und können diesem nach Hochklappen einer Verschlußlasche entnommen werden.The commercial button cells of the rechargeable Ni / Cd system or button cells of the primary systems Ag₂O / Zn and HgO / Zn usually reach the end consumer in relatively complex packaging. Examples of such containers can be found in US Pat. No. 3,414,161 or DE-AS 25 45 049. All of them are similar in their basic structure, consisting of two round plastic housing shells, one of which has compartments arranged in a circular manner to accommodate the button cells, and both of which are joined together so that one housing shell can be rotated against the other shell . The button cells are brought in line with an output outlet on the non-segmented, smooth housing shell and can be removed after folding up a closure flap.

Mit der Einführung von Zink/Luft-Knopfzellen auf dem Markt stellte sich das Problem einer Verpackung, bei welcher die im Kathodenbecher vorhandenen Lufteinlaßöffnungen vor dem Eindringen von Umgebungsluft unbedingt ge­schützt werden mußten. Abgesehen vom Sauerstoff, der mit der negativen Elektrode reagiert und diese allmählich in inaktives Zinkoxid umwandelt, macht eindringendes Kohlendioxid den Laugeelektrolyten durch Karbonatbil­dung unbrauchbar. Ferner kann Wasser in die Zelle eindringen, wenn die re­lative Feuchte der Außenatmosphäre höher ist als diejenige über dem Elektro­lyten, oder sie kann austrocknen, wenn die relative Feuchte draußen kleiner ist. Kapazitätsverluste der Zellen während der Lagerhaltung sind in allen die­sen Fällen unausbleiblich.With the introduction of zinc / air button cells on the market, there was the problem of packaging in which the air inlet openings in the cathode cup had to be protected against the ingress of ambient air. Apart from the oxygen, which reacts with the negative electrode and gradually converts it into inactive zinc oxide, penetrating carbon dioxide renders the lye electrolyte unusable due to the formation of carbonate. Furthermore, water can enter the cell if the relative humidity of the outside atmosphere is higher than that above the electrolyte, or it can dry out if the relative humidity outside is lower. Loss of capacity of the cells during storage is inevitable in all these cases.

Eine bekannte Lösung für dieses Problem stellt eine Batterie-Verpackung gemäß US-PS 4,015,708 in der Form eines Falt-Etuis dar. Das Etui besitzt eine flache Einlage aus z.B. steifem Karton mit mehreren runden Aussparungen für die aufzunehmenden Zink/Luft-Zellen und mit einer Rückwand aus Polyester, an welche die Zellen mit den Gehäuseböden durch ein Klebemittel leicht angeklebt sind. Die Polyesterfolie hält Sauerstoff, Kohlendioxid und Feuchtig­keit von den Bodenöffnungen fern, gestattet aber einen Durchtritt von Wasser­stoff von drinnen nach draußen in solchem Umfang, daß kein Überdruck entste­hen kann, bei dem sich die Folie von dem Klebemittel trennt.A known solution to this problem is a battery packaging according to US Pat. No. 4,015,708 in the form of a folding case. The case has a flat insert made of, for example, rigid cardboard with several round cutouts for the zinc / air cells to be picked up and with a back wall made of polyester, to which the cells with the housing bottoms are easily glued by an adhesive. The polyester film keeps oxygen, carbon dioxide and moisture away from the bottom openings, but allows hydrogen to pass from inside to the outside to such an extent that there can be no excess pressure at which the film separates from the adhesive.

Es ist auch bekannt, die Zellen einzeln am Becherboden mit Etiketten abzukle­ben. Diese Etiketten sind aufgebaut aus einem zweilagigen Laminat Polyester­folie und bedrucktem Papier, zusätzlich versehen mit einer vollflächigen Per­manentkleberschicht auf Kautschukbasis.It is also known to tape the cells individually on the bottom of the cup with labels. These labels are made up of a two-layer laminate of polyester film and printed paper, additionally provided with a full-surface permanent adhesive layer based on rubber.

Indessen hat sich gezeigt, daß die Etikettierung eine ganze Reihe von Schwachstellen aufweist. Bei Knopfzellen mit allgemein üblichen Lagerzeiten von 6 - 24 Monaten altern z.B. diese Kautschukkleber und lassen in Ihrer Klebekraft nach. Dadurch können sich in der Kleberschicht Luftkanäle bilden, die Ursache von Zellenausfällen sind.However, it has been shown that the labeling has a number of weak points. For button cells with generally common storage times of 6 - 24 months, e.g. these rubber adhesives and their adhesive strength will decrease. As a result, air channels can form in the adhesive layer, which are the cause of cell failures.

Auch sonst können die Kleberschichten Fehlstellen aufweisen in Form kleber­freier Linien und Nester, die bereits von Anfang an Luftzutritt ermöglichen. Becherböden mit Schmutz,- Fett- oder Olsresten reduzieren die Haftung der Kleber ganz erheblich. Ein zusätzlicher Nachteil ist bei obigen Kontakt­klebern, daß sie nur bei entsprechendem Anpreßdruck ihre optimale Haftkraft entwickeln. Des weiteren brauchen die Haftkleber möglichst große Kontakt­flächen. Die erforderlichen Becherprägungen müssen daher auf ein Minimum reduziert werden.Otherwise, the adhesive layers can have imperfections in the form of adhesive-free lines and nests, which allow air to enter from the start. Cup bottoms with dirt, grease or oil residues reduce the adhesive's adhesion considerably. An additional disadvantage with the above contact adhesives is that they only develop their optimal adhesive force when the appropriate contact pressure is applied. Furthermore, the pressure sensitive adhesives need the largest possible contact areas. The required embossed cups must therefore be reduced to a minimum.

Bei der weiter oben erwähnten Kartonhalterung kommt als eine umständliche Maßnahme hinzu, daß sie vorbeugend mit neutralisierenden Salzen imprägniert werden muß, um einen Schaden durch Elektrolytaustritt zu begrenzen.In the case of the cardboard holder mentioned above, a cumbersome measure is that it must be impregnated with neutralizing salts in order to limit damage caused by electrolyte leakage.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Verpackungselement für Luftsauerstoffelemente, insbesondere zur Verwendung in Hörgeräten anzuge­ben, das luftdicht und wasserdampfdicht ist, die erwähnten Nachteile vermei­det und zudem vollautomatische Verpackungsabläufe ermöglicht.The invention is therefore based on the object of specifying a packaging element for atmospheric oxygen elements, in particular for use in hearing aids, which is airtight and water vapor-tight, avoids the disadvantages mentioned and, moreover, enables fully automatic packaging processes.

Die Aufgabe wird erfindungsgemäß mit den im kennzeichnenden Teil des An­spruchs 1 angegebenen Mitteln gelöst.The object is achieved with the means specified in the characterizing part of claim 1.

Das Verpackungselement ist demnach im wesentlichen aus zwei Folien zusam­mengesetzt, von denen die eine durch ihre Formgebung als Behältnis fungiert und die andere dieses verschließt. Durch Versiegelung mittels Wärmekontakt, Wärmeimpuls, Hochfrequenz, Ultraschall oder Reibungswärme werden die beiden Verpackungsteile fest miteinander verbunden, wobei in der Regel die Verschlußfolie glattflächig über der die Zelle aufnehmenden Folie liegt.The packaging element is therefore essentially composed of two foils, one of which functions as a container due to its shape and the other seals it. The two packaging parts are firmly connected to one another by sealing by means of heat contact, heat pulse, high frequency, ultrasound or frictional heat, the sealing film generally lying smoothly over the film holding the cell.

Die erfindungsgemäß verwendeten Folien tragen durch ihre Materialauswahl und ihre Stärke der Forderung nach unbedingter Undurchlässigkeit für Luft und Wasserdampf Rechnung.The films used according to the invention take account of the requirement for unconditional impermeability to air and water vapor due to their material selection and their strength.

Während die zur Aufnahme der Zellen bestimmte und mit napfförmigen Vertie­fungen versehene Folie aus einem Kunststoff mit entsprechender Eigenschaft besteht, ist die aufgesiegelte Verschlußfolie vorzugsweise eine Metallfolie, insbesondere aus Aluminium, mit einer zum Heißversiegeln aufkaschierten Klebeschicht.While the film intended for receiving the cells and provided with cup-shaped depressions consists of a plastic with a corresponding property, the sealed sealing film is preferably a metal film, in particular made of aluminum, with an adhesive layer laminated on for heat sealing.

Geeignete Kunststoffe für die napfartig ausgeformte Folie sind u.a. Polyvinyl­chlorid (PVC) und Polyvinylidenchlorid (PVDC), von denen sich das letztge­nannte Material durch besonders gutes Sperrvermögen gegenüber Wasserdampf auszeichnet.Suitable plastics for the cup-shaped film include Polyvinyl chloride (PVC) and polyvinylidene chloride (PVDC), of which the latter material is characterized by particularly good barrier properties against water vapor.

Die Verformung dieser Folien, die im Ausgangszustand eine Dicke von 0,2 bis 0,5 mm aufweisen und vorteilhafterweise durchsichtig sind, geschieht durch Wärmetiefziehen.The deformation of these foils, which in the initial state have a thickness of 0.2 to 0.5 mm and are advantageously transparent, takes place by deep drawing.

Im Gegensatz zu dem zähen und reißfesten Napfmaterial, mit dem sich zwangsläufig eine gewisse Starrheit verbindet, ist die aufgesiegelte Verschluß­folie relativ dünn und kann daher leicht aufgerissen oder abgelöst werden. Eine erfindungsgemäß verwendbare Aluminiumfolie ist etwa 0,02 bis 0,03 mm dick. Der Verpackungsinhalt wird dann zwecks Entnahme einfach durch die Alu­miniumfolie gedrückt, da diese leicht aufplatzt.In contrast to the tough and tear-resistant cup material, which inevitably combines with a certain rigidity, the sealed sealing film is relatively thin and can therefore be easily torn open or detached. An aluminum foil which can be used according to the invention is approximately 0.02 to 0.03 mm thick. The contents of the packaging are then simply pushed through the aluminum foil for removal, as this easily bursts open.

Für den Versand und Lagerung von Luftsauerstoffelementen in Klimazonen mit extrem hoher bzw. niedriger Luftfeuchte kann die Schutzwirkung der Ver­packung durch die Verwendung von Kunststoff/Metall-Verbundfolien sowohl auf Behälter-Seite als auch auf Seiten der Abdeckung weiter erhöht werden. Ein absolut wasserdampfdichtes Napfmaterial setzt sich z.B. aus fünf Schich­ten, nämlich einer Kunststoff-Stützfolie, einem ersten Kaschierkleber, einer Aluminiumfolie, einem zweiten Kaschierkleber sowie einer siegelbaren Kunst­stoff-Folie zusammen und ist durch diesen Aufbau relativ starr. Dagegen kann ein flexibles Napfmaterial z.B. aus einem 3-Schicht-Verbund, Kunststoff-­Stützfolie - Kaschierkleber - Aluminiumfolie, bestehen, dem sich aluminiumseitig noch eine Heißsiegelschicht zum Verbinden mit der Verschlußfolie anfügt.For the shipping and storage of atmospheric oxygen elements in climatic zones with extremely high or low air humidity, the protective effect of the packaging can be further increased by using plastic / metal composite films on the container side as well as on the cover side. An absolutely water-vapor-proof bowl material e.g. composed of five layers, namely a plastic backing film, a first laminating adhesive, an aluminum foil, a second laminating adhesive and a sealable plastic film and is relatively rigid due to this structure. In contrast, a flexible cup material e.g. consist of a 3-layer composite, plastic backing film - laminating adhesive - aluminum foil, to which there is also a heat-sealing layer on the aluminum side for connection to the sealing film.

Aus einem ähnlichen Schichten-Verbund kann aber auch die Verschlußfolie selbst gebildet sein. In diesem Fall muß jedoch die Packung zur Produktentnah­me eingerissen werden, da die Kunsstoffkomponente die mechanische Wider­standsfähigkeit der Verschlußfolie erhöht, so daß sie nicht mehr durchdrückbar ist.However, the sealing film itself can also be formed from a similar layer composite. In this case, however, the package must be torn to remove the product, since the plastic component increases the mechanical resistance of the sealing film, so that it can no longer be pushed through.

In einer weiteren Ausführungsform der Erfindung wird das Verpackungselement nur von zwei aufeinandergesiegelten Behälter-Folien gebildet, deren napfarti­ge Ausformungen, einander gegenüberliegend, sich zu einer hermetisch dichten Kapsel ergänzen.In a further embodiment of the invention, the packaging element is formed only by two container films sealed to one another, the cup-like formations of which lie opposite one another and complement one another to form a hermetically sealed capsule.

Bei den napfförmigen Kunststoff/Aluminium-Verbundfolien wird ein entspre­chend abgestimmtes Streckziehen eingesetzt.A suitably coordinated stretching process is used for the cup-shaped plastic / aluminum composite films.

Der große Vorteil der erfindungsgemäßen Verpackung liegt allgemein in der Heißversiegelung der beiden Verpackungsteile, welche hinsichtlich Verpackungsicherheit einer Abklebung mittels Etiketten weit überlegen ist. Die auf die Metallfolie aufgetragenen Heißsiegelkleber schmelzen nur bei Wärmekontakt oberhalb 90°C. Im gehärteten Zustand bei Raumtemperatur ist ihre Klebekraft erheblich höher als diejenige von Kontaktklebern.The great advantage of the packaging according to the invention generally lies in the heat sealing of the two packaging parts, which is far superior to masking by means of labels in terms of packaging security. The heat seal adhesives applied to the metal foil only melt when they come into contact with heat above 90 ° C. In the hardened state at room temperature, their adhesive strength is considerably higher than that of contact adhesives.

Beispiele für erfindungsgemäße Verpackungen sind in zwei Figuren dargestellt.

  • Figur 1 zeigt eine Durchdrückpackung.
  • Figur 2 zeigt eine Einreißpackung.
Examples of packaging according to the invention are shown in two figures.
  • Figure 1 shows a blister pack.
  • Figure 2 shows a tear pack.

Gemäß Figur 1 wird bei einem als Beispiel gewählten Sechser-Pack 1 die Ober­seite von einer transparenten Kunststoffolie 2 mit napfförmigen Ausprägungen 3 gebildet, welche die Knopfzellen 4 aufnehmen und eine kreisförmige Anord­nung besitzen. Auf ihrer Unterseite ist die Kunststoffolie durch eine Aluminiumfolie 5 glattflächig versiegelt, so daß die Knopfzellen hermetisch verkapselt sind. Durch das Versiegelungswerkzeug (Walze oder Stempel) erhält die Aluminiumfolie eine rasterähnliche Textur, die wegen der Durchsichtigkeit der Folie 2 auch von oben her sichtbar ist. Aus dem vordersten Napf wurde eine Knopfzelle, indem sie durch die Aluminiumfolie 5 hindurchgedrückt wurde, bereits entnommen.According to FIG. 1, in a six-pack 1 chosen as an example, the upper side is formed by a transparent plastic film 2 with cup-shaped features 3, which receive the button cells 4 and have a circular arrangement. The plastic film is sealed on its underside by an aluminum film 5 so that the button cells are hermetically encapsulated. The sealing tool (roller or stamp) gives the aluminum foil a grid-like texture, which is also visible from above due to the transparency of the foil 2. A button cell has already been removed from the foremost bowl by pushing it through the aluminum foil 5.

Bei der in Figur 2 als Vierer-Pack 6 wiedergegebenen Einreißpackung sind zwei gleiche, durch Streckziehen hergestellte Kunststoff/Aluminium-Verbundfolien 7 aufeinandergesiegelt. Die Festigkeit des mehrlagigen Napfmaterials erlaubt eine Entnahme der Knopfzellen 4 nur durch Einreißen.In the case of the tear pack shown in FIG. 2 as a four-pack 6, two identical plastic / aluminum composite films 7 produced by stretch-drawing are sealed to one another. The strength of the multi-layer cup material allows the button cells 4 to be removed only by tearing.
