Abstract

The package (1), which is impermeable to air and water vapour and is intended, in particular, for zinc/air hearing aid batteries of the button cell type, is formed partially from a tear-resistant, preferably transparent film (2) of PVC or polyvinylidene chloride with cup-shaped elevations (3) for accommodating the button cells and partially from an aluminium closure foil (5) which is sealed flatly onto said film. To remove a button cell (4), the latter needs only to be pressed from the outside through the easily tearable aluminium foil. In the case of particularly reliable packages for despatch to areas with an extremely humid or dry climate, both the cup film and the closure foil can be based on a multi-layered plastic/metal composite material. <IMAGE>

Opfindelsen angår et pakningselement til lagring af galvaniske 1 uftoxygenceller under lufttæt tillukning, indtil de skal tages i brug. Sådanne 1 uftoxygencel1 er er f.eks. anvendt i forbindelse med høreapparater.The present invention relates to a packing element for storing galvanic 1 uftoxygen cells during airtight closure until they are put into service. Such 1 uftoxygencel1 is e.g. used in conjunction with hearing aids.

Genopladelige Ni/Cd-knapcel1 er eller Ag20/Zn eller HgO/Zn knapceller leveres for det meste til brugeren i forholdsvis dyre pakninger, jf. US patentskrift nr. 3.414.161. Disse pakninger består af to runde plastskaller, af hvilke den ene har 10 et rundt hulrum til optagelse af en knapcelle. Skallerne er således sammenføjet, at den ene skal kan drejes i forhold til den anden. Knapcellerne afdækkes derved en efter en, hvorefter de vil kunne udtages ved oplukning af en lukkelaske.Rechargeable Ni / Cd button cells or Ag20 / Zn or HgO / Zn button cells are mostly supplied to the user in relatively expensive packages, cf. US Patent No. 3,414,161. These seals consist of two round plastic shells, one of which has a round cavity for receiving a button cell. The shells are joined together so that one shell can be rotated relative to the other. The button cells are thereby uncovered one by one, after which they can be removed by opening a closure bag.

15 Ved pakning af zink/1uftknapce11 er opstod der imidlertid et problem, idet lufttilgangsåbninger i katodebægeret skulle beskyttes mod indtrængning af luft fra omgivelserne. Ud over at ilt kan reagere med den negative elektrode og omsætte denne til inaktivt zinkoxid, vil en indtrængende kuldioxid også 20 kunne gøre den basiske elektrolyt uanvendelig som følge af carbonatdanneIser. Endvidere kan der trænge vand ind i cellen, hvis den relative fugtighed af omgivelsernes luft er højere end fugtigheden over elektrolytten, eller elektrolytten vil kunne udtørre, hvis den relative fugtighed af omgivelsernes 25 luft er mindre end fugtigheden over elektrolytten. Cellens kapacitet kan derved blive reduceret under lagring.15 However, when packing zinc / 1 air button 11, a problem arose, as air inlet openings in the cathode cup had to be protected from air penetration from the surroundings. In addition to oxygen being able to react with the negative electrode and convert it to inert zinc oxide, an ingress of carbon dioxide could also render the basic electrolyte unusable due to carbonate formation. Furthermore, water may enter the cell if the relative humidity of the ambient air is higher than the humidity above the electrolyte or the electrolyte may dry out if the relative humidity of the ambient air is less than the humidity above the electrolyte. The capacity of the cell can thereby be reduced during storage.

Fra US patentskrift nr. 4.015.708 kendes en batteri pakn i ng, der løser dette problem ved hjælp af et foldeetui. Etuiet har 30 et fladt indlæg af f.eks. stift karton med et antal runde udsparinger til optagelse af zink/1uft-cel1 er og en bagvæg i form af en polyesterfolie, idet cellerne vil kunne fastklæbes til folien ved hjælp af klæbemiddel. Polyesterfolien hindrer en indtrængning af oxygen, kultveilte og fugt via åbningerne i 35 bunden af det enkelte cellebæger. Hydrogen vil imidlertid kunne trænge ind i et sådant omfang, at der kan opstå et overtryk, hvorved polyesterfolien vil kunne adskilles fra bunden af cellebægeret.From U.S. Patent No. 4,015,708, a battery pack is known which solves this problem by means of a folding case. The case has a flat insert of e.g. rigid cardboard with a number of circular recesses for receiving zinc / 1uft cell 1 and a back wall in the form of a polyester film, the cells being able to be adhered to the film by adhesive. The polyester foil prevents the penetration of oxygen, carbon dioxide and moisture through the openings in the bottom of the individual cell cup. However, hydrogen will be able to penetrate to such an extent that an overpressure may occur whereby the polyester film can be separated from the bottom of the cell cup.

Det er også kendt at klæbe etiketter på bunden af det enkelte cellebæger. Disse etiketter udgøres af en tolaget laminatpoly-esterfolie samt et lag trykt papir med kautschukklæbemiddel over hele fladen.It is also known to stick labels on the bottom of the individual cell cup. These labels consist of a two-layered laminate polyester film and a layer of printed paper with rubber shock adhesive all over the surface.

55

En sådan etikettering har imidlertid flere svage punkter. Ved knapceller, der har ligget på lager i 6-24 måneder, kan kaut-schukklæbemidlet være ændret, og vedhæftningen kan være reduceret. I klæbemidlet kan der derved dannes luftkanaler, hvil-10 ket kan forårsage udfald af celler. Klæbemiddel lagene kan også have fejlsteder i form af klæbefri linier og huller, der allerede fra begyndelsen muliggør en lufttilgang. Bægerbunde med urenheder, såsom fedtstoffer og olierester reducerer også ved-hæftningen af klæbemidlet. En yderligere ulempe ved det nævnte 15 klæbemiddel er desuden, at det kun ved et passende tryk giver en optimal vedhæftning. Endvidere behøver klæbemidlet en forholdsvis stor kontaktflade. Eventuelle prægninger på bægeret må derfor reduceres til et minimum for ikke at reducere kontaktf 1 aden.However, such labeling has several weaknesses. For button cells that have been in storage for 6-24 months, the cautious shock adhesive may have changed and the adhesion may have been reduced. Air ducts can thereby be formed in the adhesive, which can cause cell failure. The adhesive layers may also have defect points in the form of adhesive-free lines and holes, which from the outset enable an air supply. Cup bottoms with impurities such as fats and oil residues also reduce the adhesion of the adhesive. A further disadvantage of said adhesive is that it provides only an optimal adhesion at an appropriate pressure. Furthermore, the adhesive needs a relatively large contact surface. Therefore, any imprints on the cup must be reduced to a minimum so as not to reduce the contact surface.

Fra tysk offentliggørelsesskrift nr. 2.335.123 kendes en "verbundfolie" til fremstilling af gennemtrykspakninger. Der er imidlertid kun anvendt en aluminiumsdækfolie på den ene side af gennemtrykspakningen.German publication specification No. 2,335,123 discloses a "compound foil" for the production of pressure seals. However, only one aluminum cover film is used on one side of the pressure seal.

Formålet med opfindelsen er at anvise et pakningselement til 1 uftoxygencel1 er, især til anvendelse i høreapparater, og som er luft- og damptæt, og som ikke har de ovennævnte ulemper, og som desuden muliggør en fuldautomatisk pakning.The object of the invention is to provide a gasket element for 1 uftoxygen cell 1, especially for use in hearing aids, which are air and vapor tight and which do not have the disadvantages mentioned above, and which furthermore enable a fully automatic gasket.

Et pakningselement af den indledningsvis nævnte art er ifølge opfindelsen ejendommeligt ved, at det består af en til cellens ydre mål i det væsentlige tilpasset skålformet beholder af et laminat bestående af en plastfolie og en metalfolie, der er 35 uigennemtrængeligt for luft og vanddamp, på hvilket laminat der er forseglet en lukkefolie af metal eller af forbundne plast- og metalfolier, der ligeledes er uigennemtrængelige for luft og vanddamp, og som kan afrives eller frigøres.According to the invention, a packing element of the kind mentioned in the invention is characterized in that it consists of a substantially adapted bowl-shaped container of a laminate consisting of a plastic film and a metal film impervious to air and water vapor, on which laminate which is sealed a metal sealing film or of associated plastic and metal foils which are also impermeable to air and water vapor and which can be peeled off or released.

Pakningselementet er derved sammensat af to folier, af hvilke i hvert fald det ene gennem sin formgivning fungerer som beholder, og den anden lukker denne beholder. Ved en forsegling med varmekontakt, varmeimpulsti 1førsel, højfrekvens, ultralyd 5 eller friktionsvarme, bliver pakningselementets to folier forbundet indbyrdes, hvorved lukkefolien i regelen kommer til at ligge glat over den folie, der fungerer som beholder for cel-1 en.The packing element is thereby composed of two sheets, at least one of which, through its shaping, acts as a container and the other closes this container. In a sealing with heat contact, heat impulse path, high frequency, ultrasonic 5 or frictional heat, the two foils of the packing element are interconnected, whereby the closing foil will generally lie smoothly over the foil which serves as the container for the cell-1.

10 De anvendte folier skulle, ud fra materialevalg og tykkelse, være ubetinget uigennemtrængelige for luft og vanddamp.10 The films used should, based on material selection and thickness, be unconditionally impermeable to air and water vapor.

Selv om folierne med skålformede fordybninger består af et laminat af metal og plastmateriale, er den forseglede lukkefolie 15 fortrinsvis en metalfolie, fortrinsvis en aluminiumsfolie med et klæbelag.Although the foil-shaped foil films consist of a metal and plastic laminate, the sealed foil 15 is preferably a metal foil, preferably an aluminum foil with an adhesive layer.

Egnede plastmaterialer til den skålformede folie er f.eks. po-lyvinylchlorid (PVC), og polyvinyl idenchlorid (PVDC), af hvi 1 -20 ke sidstnævnte udmærker sig ved en god spærreevne over for vanddamp.Suitable plastics materials for the bowl-shaped foil are e.g. polyvinyl chloride (PVC) and polyvinyl idene chloride (PVDC), of which 1 -20 ke the latter are distinguished by a good water vapor barrier.

Formningen af disse folier, der i udgangstilstand har en tykkelse på 0,2-0,5 mm, sker ved varmdybtrækning.The molding of these foils, which in the initial state has a thickness of 0.2-0.5 mm, is done by hot dip.

25 I modsætning til den seje og brudfaste skålformede del, som har en vis stivhed, er den forseglede lukkefolie forholdsvis tynd og kan let afrives eller frigøres. En passende lukkefolie i form af en aluminiumsfolie har en tykkelse på ca. 0,02-0,03 30 mm.25 Unlike the tough and fracture-shaped bowl-shaped portion which has some stiffness, the sealed closure film is relatively thin and can be easily torn off or released. A suitable sealing foil in the form of an aluminum foil has a thickness of approx. 0.02-0.03 30 mm.

En celle i pakningselementet trykkes let ud gennem aluminiumsfolien, da denne let brydes.A cell in the gasket element is easily pushed out through the aluminum foil as it is easily broken.

35 Til forsendelse og lagring af 1 uftoxygenceller i klimazoner med ekstrem høj henholdsvis ekstrem lav luftfugtighed, kan beskyttelsesvirkningen af pakningselementet forbedres ved anven-For shipping and storing 1 uftoxygen cells in climate zones with extremely high and extremely low humidity, the protective effect of the packing element can be enhanced by the use of

4 delse af forbundne plast- og metalfolier, såvel på beholdersiden som på afdækningssiden. En absolut damptæt skålformet del er f.eks. sammensat af fem lag, nemlig en piast-beskyttel-sesfolie, et første klæbelag, en aluminiumsfolie, et andet klæ-5 belag, samt en forseglelig plastfolie, og er gennem denne opbygning forholdsvis stiv. En fleksibel skålformet del kan f.eks. bestå af en forbindelse af en plastfolie, et klæbelag og en aluminiumsfolie, idet der til aluminiumsiden er tilføjet et varmforsegleligt lag, der kan forbindes med lukkefolien.4 for bonded plastic and metal foils, both on the container side and on the cover side. An absolutely vapor-proof bowl-shaped portion is e.g. composed of five layers, namely a piast protective film, a first adhesive layer, an aluminum foil, a second adhesive coating, and a sealable plastic film, and are relatively rigid throughout this structure. A flexible bowl-shaped part can e.g. consist of a connection of a plastic film, an adhesive layer and an aluminum foil, a heat-sealable layer which can be connected to the closure foil is added to the aluminum side.

1010

Lukkefolien kan dannes ved en tilsvarende forbindelse af lag.The closure foil can be formed by a corresponding layer of layers.

I dette tilfælde må der dog skæres i pakningen til udtagning af indholdet, da plastkomponenterne øger den mekaniske modstandsstyrke af lukkefolien, således at denne ikke længere er 15 let at bryde.In this case, however, the packing must be cut to remove the contents as the plastic components increase the mechanical resistance of the closure foil so that it is no longer easy to break.

I en yderligere udførelsesform bliver pakningselementet dannet af to på hinanden forseglede beholderfolier, hvis skålformede dele ligger over for hinanden til afgrænsning af en hermetisk 20 tæt kapsel.In a further embodiment, the packing element is formed by two sealed container foils, the bowl-shaped portions of which are opposite one another to define a hermetically sealed capsule.

Ved de skålformede forbundne plast- og aluminiumsfolier anvendes en passende strækretning.A suitable stretching direction is used for the bowl-shaped plastic and aluminum foils.

25 Den store fordel ved pakningselementet ifølge opfindelsen ligger i varmforseglingen, der er påklæbningen af etiketter stærkt overlegen i henseende til sikkerhed. Den på metal folierne påførte varmforseglingsklæber smelter ved en varmekontakt på 90eC eller derover. I hærdet tilstand ved stuetemperatur har 30 den en væsentlig højere klæbeevne end kontaktklæberen.The great advantage of the packaging element according to the invention lies in the heat seal, which is the adhesive of labels strongly superior for safety. The heat sealing adhesives applied to the metal foil melt at a heat contact of 90 ° C or more. When cured at room temperature, it has a substantially higher adhesive capacity than the contact adhesive.

Et eksempel på et pakningselement ifølge opfindelsen er vist på tegningen.An example of a packing element according to the invention is shown in the drawing.

35 Ved det på tegningen viste pakningselement i form af en fire-stykspakke 6 er to ens ved trækning formede laminater bestående af en plastfolie og en aluminiumsfolie 7 forseglet til hin-In the drawing element shown in the drawing, in the form of a four-piece package 6, two similarly drawn laminates consisting of a plastic film and an aluminum foil 7 are sealed to each other.
