Abstract
Description
Oppfinnelsen vedrører blæreformede Innpakninger, i det følgende kalt bl 1ster-paknlnger og nærmere bestemt en blister-innpaknlng for oppbevaring og avgivelse av hydrofile kontaktlinser som holdes 1 en vanndig oppløsning. The invention relates to blister-shaped packages, hereinafter called blister packages and more specifically a blister package for storing and dispensing hydrophilic contact lenses which are held in an aqueous solution.
Myke, hydrofile kontaktlinser tilvirkes av hydrofilt polymert materiale slik som kopolymerer av hydroksyletyl metakrylat og kan Inneholde fra 20 - 90$ eller mer vann, avhengig av polymersammensetning. Slike linser må oppbevares i en steril vanndig oppløsning, vanligvis isotonisk saltoppløsning for å forghindre dehydratisering og for å opprettholde linsene i en tilstand klar for bruk. Soft, hydrophilic contact lenses are made from hydrophilic polymeric material such as copolymers of hydroxylethyl methacrylate and can contain from 20 - 90$ or more water, depending on the polymer composition. Such lenses must be stored in a sterile aqueous solution, usually isotonic saline, to prevent dehydration and to maintain the lenses in a ready-to-use condition.
Vanlig praksis for linsefabrikanter har vært å bruke plottede glassflasker som lagrings- og transportbeholder for hver individuell linse. Standardflasken for kontaktlinser er omkring 10 cm<3> i volum, er forseglet med en silikonpropp og anordnet med en overtrukket metallfolie som sikkerhetsforseg-ling. Hver flaske inneholder omkring 7 cm<3> saltoppløsning og en enkelt kontaktlinse som er identifisert på flaskens merkelapp. Når linsen skal tas ut for anpasning på en pasient, må den praktiserende først rive av og fjerne metallsikkerhetsforseglingen, så fjerne proppen, og til slutt ta ut linsen med en plastpinsett. Common practice for lens manufacturers has been to use plotted glass bottles as storage and transport containers for each individual lens. The standard bottle for contact lenses is about 10 cm<3> in volume, is sealed with a silicone stopper and arranged with a coated metal foil as a safety seal. Each bottle contains approximately 7 cm<3> of saline solution and a single contact lens identified on the bottle's label. When removing the lens for fitting on a patient, the practitioner must first tear off and remove the metal safety seal, then remove the stopper, and finally remove the lens with plastic tweezers.
Pakking av kontaktlinser i glassflasker er kostbart på grunn av flaskenes kostnad, proppene og forseglingene, og frakten er kostbar på grunn av vekten på flaskene og saltoppløs-ningen. Flaskene er også utsatt for brekkasje dersom de utilsiktet mistes under håndtering, og uttak av linsen fra flasken med pinsetter er ubehendig siden linsen er nesten usynlig når neddykket i saltoppløsning. Det er følgelig et formål med den foreliggende oppfinnelse å tilveiebringe en forbedret pakning for oppbevaring, frakt og avgivelse av hydrofile kontaktlinser. Det er videre et formål med denne oppfinnelse å tilveiebringe en linseinnpakning som tillater forbedret effektivitet i linsens tilvirkningsprosess. Det er enda et formål med den foreliggende oppfinnelse å tilveiebringe en ukostbar innpakning som tillater behendig uttak av kontaktlinsen. Disse og andre formål med oppfinnelsen vil fremkomme av den følgende beskrivelse og kravene. Packing contact lenses in glass bottles is expensive because of the cost of the bottles, the stoppers and the seals, and shipping is expensive because of the weight of the bottles and the salt solution. The bottles are also susceptible to breakage if they are accidentally dropped during handling, and removing the lens from the bottle with tweezers is awkward since the lens is almost invisible when immersed in saline solution. Accordingly, it is an object of the present invention to provide an improved package for storing, shipping and dispensing hydrophilic contact lenses. It is further an object of this invention to provide a lens packaging which allows improved efficiency in the lens manufacturing process. It is a further object of the present invention to provide an inexpensive packaging which allows for convenient removal of the contact lens. These and other objects of the invention will appear from the following description and the claims.
Innpakningen ifølge den foreliggende oppfinnelse er en tilformet blister-pakning dekket med et fleksibelt platemateriale som kan rives av fra pakningen for å gi adkomst til linsen. Den støpe basis eller blisterpartiet av pakningen innbefatter et hulrom for å oppta kontaktlinsen og saltopp-løsning, og en utad forløpende flens rundt omkretsen av hulrommet til hvilke dekselmaterialet er forseglet. Pakning-ens hulrom er definert ved en nedre flate og sidevegger som forløper mellom den nedre overflate og den omkretsmessige flens. Et parti av sideveggen er skråstilt bort fra bunnflaten for å danne en rampe eller skrånende flate mellom bunnen av hulrommet og flensen. Dekselmaterialet er forseglet til flensen rundt hulrommet ved hjelp av hvilke dekselet tillates å hurtig trekkes eller skrelt av fra flensen. Flensen inntil den skrånende flate og det overliggende dekselmateriale forløper utad forbi forseglingsområdet for å tilveiebringe uforseglede kanter som kan gripes for å lette fjerning av dekselet. The packaging according to the present invention is a shaped blister pack covered with a flexible sheet material which can be torn off from the packaging to give access to the lens. The molded base or blister portion of the package includes a cavity to receive the contact lens and saline solution, and an outwardly extending flange around the perimeter of the cavity to which the cover material is sealed. The gasket's cavity is defined by a lower surface and side walls extending between the lower surface and the circumferential flange. A portion of the side wall is sloped away from the bottom surface to form a ramp or sloping surface between the bottom of the cavity and the flange. The cover material is sealed to the flange around the cavity by means of which the cover is allowed to be quickly pulled or peeled off from the flange. The flange adjacent to the inclined surface and the overlying cover material extend outward past the sealing area to provide unsealed edges which can be gripped to facilitate removal of the cover.
Pakningen ifølge den foreliggende oppfinnelse er ukostbar, av lav vekt og krever mindre saltoppløsning for linseoppbevar-ing. Pakningen åpnes hensiktsmessig ved å trekke av dekselet fra flensen for å eksponere hulrommet og linsen i et grunt bad av saltoppløsning. Linsen fjernes hensiktsmessig ved å skli linsen opp den skrå flate ved bruk av enten pinsett eller en finger. The package according to the present invention is inexpensive, of low weight and requires less salt solution for lens storage. The package is conveniently opened by pulling the cover off the flange to expose the cavity and lens in a shallow bath of saline solution. The lens is conveniently removed by sliding the lens up the inclined surface using either tweezers or a finger.
Basispartiet av pakningen kan være sprøytestøpt eller termoformet fra ethvert egnet termoplastisk platemateriale slik som polypropylen. Dekselforrådet kan være et laminat av polypropylenf i lm og aluminiumsfolie som kan varmeforsegles til flensen rundt hulrommet av pakningen. Linseidentifikasjon og annen merkelappinformasjon kan trykkes på dekselmaterialet. Når pakningen åpnes og steriliteten går tapt, er pakningen ikke foranderlig for å lukke seg igjen. The base portion of the gasket may be injection molded or thermoformed from any suitable thermoplastic sheet material such as polypropylene. The cover stock can be a laminate of polypropylene f i lm and aluminum foil which can be heat sealed to the flange around the cavity of the gasket. Lens identification and other label information can be printed on the cover material. When the package is opened and sterility is lost, the package is not changeable to close again.

Med henvisning til fig.l er det illustrert en foretrukken utførelse av en pakning ifølge den foreliggende oppfinnelse innbefattende et nedre basisparti 11 og dekselelement 12. Det nedre parti innbefatter et hulrom indikert generelt som 13 som er formet ved den skrånende sidevegg 14 og de oppadstående sidevegger 15. Hulrommet er omgitt av en utad forløpende flens 16. Dekselet 12 er forseglet til flensen 16 rundt åpningen av hulrommet 13 som indikert ved forseglingslinjen 17. Hulrommet 13 er dimensjonert til å motta kontaktlinsen 19 og en tilstrekkelig mengde saltoppløsning 20 for fullstendig å neddykke linsen. With reference to Fig.1, a preferred embodiment of a gasket according to the present invention is illustrated including a lower base portion 11 and cover element 12. The lower portion includes a cavity indicated generally as 13 which is formed by the sloping side wall 14 and the upstanding side walls 15. The cavity is surrounded by an outwardly extending flange 16. The cover 12 is sealed to the flange 16 around the opening of the cavity 13 as indicated by the seal line 17. The cavity 13 is sized to receive the contact lens 19 and a sufficient amount of saline solution 20 to completely immerse the lens .
Som illustrert i fig.l, forløper det parti av flensen 16 og dekselet 12 inntil den skrånende sidevegg 14 godt forbi forseglingsområdet 17. De uforseglede kanter av flensen og dekselet tilveiebringer derved gripeinnretninger hvorved dekselet kan hurtig trekkes av fra flensen for å gi adkomst til hulrommet 13 og linsen som holdes deri. En åpnet pakning med dekselelementet fortsatt festet langs den bakre kant av flensen er Illustrert i fig.2. Forseglingslinjen mellom den skrånende sidevegg 14 og de uforseglede kanter av dekselet og flensen er fortrinnsvis vinkelformet som illustrert i fig.l og 2 for å forenkle åpning av pakningen siden vinkelutform-ingen tillater at en u.er jevn avrivningskraft kan påføres, som sikrer at pakningen kan åpnes uten spill av innholdet. Fig.3 er et sideriss som tydeligst illustrerer helningen på den skrå flaten 14. Fortrinnsvis bør flaten 14 danne en stump vinkel fra omkring 130 - 160° med planet for bunnflaten av hulrommet 13 og mest fordelaktig fra omkring 140 - 150°. En helning innenfor dette området tillater lensen å bli hurtig tatt ut fra hulrommet uten unødvendig å øke volumet til hulrommet eller lengden av forseglingslinjen rundt omkretsen av hulrommet. En typisk kontaktlinse har en diameter på omkring 13 - 15 mm og en dybde på omnkring 3-4 mm. Et passende hulrom for en slik linse er fra 6 - 10 mm dypt med en bunnflate på 20 x 20 mm og en åpning på omkring 20 x 30 mm. Den ytre dimensjon av en slik pakning er omkring 3x6 cm. Fig.4 er et riss sett ovenfra av pakningen ifølge fig.l med dekselet 12 fjernet for mer tydelig å illustrere utseendet at hulrommet 13. Fig. 5 er en skisse sett ovenfra av nok en utførelse av pakningen hvor hulrommet 23 som omgir flensen 26 defineres ved en halvsirkulær oppadstående sidevegg 25 som går over til den skråstilte sidevegg 24. Fig.6 illustrerer nok en utførelse av foreliggende oppfinnelse hvor bunnflaten 28 av hulrommet 33 er konkavt. Den konkave flate oppmuntrer linsen som holdes i hulrommet til å hvile mot bunnflaten mot kantene av linsen forløpende oppad, og derved gjøre det enklere å lokalisere linsen og bringe den opp til flensen 36 av pakningen. Den skråstilte sideveggflate kan likeledes være flat eller konkav etter ønske. As illustrated in Fig.l, the portion of the flange 16 and the cover 12 extends up to the sloping side wall 14 well past the sealing area 17. The unsealed edges of the flange and the cover thereby provide gripping means whereby the cover can be quickly pulled off the flange to provide access to the cavity 13 and the lens held therein. An opened gasket with the cover element still attached along the rear edge of the flange is illustrated in Fig.2. The seal line between the sloped sidewall 14 and the unsealed edges of the cover and flange is preferably angled as illustrated in Figures 1 and 2 to facilitate opening of the gasket since the angled design allows a uniform tear-off force to be applied, which ensures that the gasket can be opened without spilling the contents. Fig.3 is a side view which most clearly illustrates the inclination of the inclined surface 14. Preferably, the surface 14 should form an obtuse angle from about 130 - 160° with the plane of the bottom surface of the cavity 13 and most advantageously from about 140 - 150°. A slope within this range allows the lens to be quickly removed from the cavity without unnecessarily increasing the volume of the cavity or the length of the seal line around the circumference of the cavity. A typical contact lens has a diameter of around 13 - 15 mm and a depth of around 3-4 mm. A suitable cavity for such a lens is from 6 - 10 mm deep with a bottom surface of 20 x 20 mm and an opening of around 20 x 30 mm. The outer dimension of such a package is around 3x6 cm. Fig.4 is a view from above of the gasket according to fig.1 with the cover 12 removed to more clearly illustrate the appearance of the cavity 13. Fig.5 is a sketch seen from above of yet another embodiment of the gasket where the cavity 23 surrounding the flange 26 is defined by a semi-circular upright side wall 25 which transitions to the inclined side wall 24. Fig.6 illustrates yet another embodiment of the present invention where the bottom surface 28 of the cavity 33 is concave. The concave surface encourages the lens held in the cavity to rest against the bottom surface against the edges of the lens extending upward, thereby making it easier to locate the lens and bring it up to the flange 36 of the gasket. The inclined side wall surface can likewise be flat or concave as desired.
Det nedre parti 12 av pakningen ifølge den foreliggende oppfinnelse fremstilles fordelaktig ved termoforming av polypropylen platemateriale som har en tykkelse på omkring 0,8 mm. Polypropylen er foretrukket for dens gode termoform-ings egenskaper og dens evne til å motstå varmesteriliser-ingstemperaturer ved omkring 120°C med liten eller ingen krynmping eller forskyvning, og dens evne til å bli varmeforseglet til dekselmaterialet. The lower part 12 of the gasket according to the present invention is advantageously produced by thermoforming polypropylene sheet material which has a thickness of about 0.8 mm. Polypropylene is preferred for its good thermoforming properties and its ability to withstand heat sterilization temperatures of about 120°C with little or no shrinkage or displacement, and its ability to be heat sealed to the cover material.
Dekselmaterialet er fortrinnsvis en addisivlaminat av aluminiumsfolie og polypropylenflim som kan varmeforsegles til basisseksjonen av pakningen for å tilveiebringe en lufttett tetning, og likevel hurtig rives av fra pakningen når pakningen skal åpnes. Aluminiumsfolien er fortrinnsvis belagt eller lakket på den motsatte overflate for å tilveiebringe merkelappidentif ikasj on og en mottagende flate for senere å inntrykke linseparametre, slik som diameter, styrke og basiskrumning. The cover material is preferably an additive laminate of aluminum foil and polypropylene film which can be heat sealed to the base section of the package to provide an airtight seal, and yet quickly torn off from the package when the package is to be opened. The aluminum foil is preferably coated or varnished on the opposite surface to provide label identification and a receiving surface for later imprinting lens parameters, such as diameter, strength and base curvature.
Pakningen ifølge den foreliggende oppfinnelse kan bygges av materialer forskjellig fra de allerede identifisert selv om de materialer som allerede er identifisert tilveiebringer gode resultater.Pakninger oppbygd av materialer slik som polyetylen som er mindre varmeresistente ell polypropylen og ikke egnet for varmesterilisering kan stråle- eller gassteri-liseres, eller alternativt med aseptiske monteringsteknikker. The package according to the present invention can be built from materials different from those already identified, even if the materials already identified provide good results. Packages built from materials such as polyethylene which are less heat resistant or polypropylene and not suitable for heat sterilization can be radiation or gas sterilized. lysed, or alternatively with aseptic mounting techniques.
I tillegg til å motstå steriliseringstemperaturer på omkring 120°C, må de forseglede pakninger for hydrofile kontaktlinser være ugjennomtrengelige for bakterier for å bevare steriliteten, ha en neglisjerbar fuktighetsoverføringsgrad for å unngå vanntap, og være istand til å opprettholde linsen i sin opprinnelige tilstand for angitte liggetider på produktet, vanligvis 2 - 4 år. Pakningsmaterialene og pakningsprose-dyrene må velges samsvarende. In addition to withstanding sterilization temperatures of around 120°C, the sealed packages for hydrophilic contact lenses must be impervious to bacteria to preserve sterility, have a negligible moisture transfer rate to avoid water loss, and be able to maintain the lens in its original state for specified shelf life of the product, usually 2 - 4 years. The packing materials and packing procedures must be selected accordingly.
Mens pakningen ifølge den foreliggende oppfinnelse som illustrert heri, har vært generelt rektangulære i form med en rektangulær eller et avlangt hulrom, skal det forstås at mange andre størrelser og former kan anvendes uten å avvike fra oppfinnelsens ramme. Pakningene ifølge den foreliggende oppfinnelse kjennetegnes ved et oppbevaringshulrom som har en skrånende vegg eller rampe som forløper fra bunnen av hulrommet til en omkretsmessig utadstående flens, og en avtagbar dekselplate forseglet tilflensen rundt omkretsen av hulrommet. Materialer, tilvirkningsmetoder og pakningsutseen-det kan variere i samsvar med de spesifikke behov og ønsker til den praktiserende person. While the packing according to the present invention as illustrated herein has generally been rectangular in shape with a rectangular or an elongated cavity, it should be understood that many other sizes and shapes can be used without deviating from the scope of the invention. The gaskets of the present invention are characterized by a storage cavity having an inclined wall or ramp extending from the bottom of the cavity to a circumferentially protruding flange, and a removable cover plate sealed to the flange around the circumference of the cavity. Materials, manufacturing methods and packaging appearance - this can vary in accordance with the specific needs and wishes of the practitioner.
