Den kremlignende konsistens for tannpleiemidler fåes typisk ved anvendelse av et gelmiddel eller bindemiddel. Tidligere er gelmidler blitt valgt primært for å gjøre det The cream-like consistency of dental care agents is typically obtained by using a gel agent or binder. In the past, gel agents have been chosen primarily to do so
lett å dispergere tannpleiemidlet i munnhulen. En rekke gelmidler, som cellulosematerialer, sjøplantederivater, gummier eller leirer, tilfredsstiller denne betingelse. Imidlertid vil enkelte gelmidler, selv om de generelt er ønskede for tannpleiemidler emballert i fleksible tuber, forårsake ulemper når tannpleiemidlene emballeres i mekanisk betjente utmatningsanordninger eller trykkforskjellsutmatningsanord-ninger. easy to disperse the toothpaste in the oral cavity. A number of gel agents, such as cellulose materials, marine plant derivatives, gums or clays, satisfy this condition. However, certain gel agents, although generally desirable for dentifrices packaged in flexible tubes, will cause disadvantages when the dentifrices are packaged in mechanically operated dispensing devices or pressure difference dispensing devices.
Tannpleiemidler som inneholder vanlige poleringsmidler, som a-aluminiumoxydtrihydrat, og vanlige gelmidler, som natriumcarboxymethylcellulose eller hydroxyethylcellulose eller blandinger derav, kan lett fylles i fleksible tuber eller mekanisk betjente utmatningsanordninger eller trykk-forskjellsutmatningsanordninger og ekstruderes fra .disse. Dentifrices containing common polishing agents, such as α-aluminum oxide trihydrate, and common gelling agents, such as sodium carboxymethylcellulose or hydroxyethylcellulose or mixtures thereof, can be readily filled into flexible tubes or mechanically operated or pressure differential dispensing devices and extruded therefrom.
Når imidlertid tannpleiemidlet inneholder en rekke aktive bestanddeler, kan vanskeligheter oppstå dersom det gjøres forsøk på å fylle et tannpleiemiddel i en mekanisk betjent utmatningsanordning eller trykkforskjellsutmatningsanordning og/eller når det gjøres forsøk på å ekstrudere tannpleiemidlet fra denne. Spesielt kan lekkasje fra åpninger i utmatnings-anordningene forekomme under ifylling eller transport, og produktet kan være vanskelig å ekstrudere med en rheologisk ønsket båndform. However, when the dentifrice contains a number of active ingredients, difficulties may arise if an attempt is made to fill a dentifrice into a mechanically operated dispensing device or pressure difference dispensing device and/or when an attempt is made to extrude the dentifrice from this. In particular, leakage from openings in the dispensing devices can occur during filling or transport, and the product can be difficult to extrude with a rheologically desired strip shape.
Tannpleiemidler som er tykke eller er tilbøyelige til Dentifrices that are thick or tend to
å bli tykke, kan for brukeren bli tiltagende vanskelige med tiden å ekstrudere fra en tannpleiemiddeltube. Med andre ord må brukeren øke trykket mot en tannpleiemiddeltube som inneholder et slikt tannpleiemiddel under brukstiden av dette for å mykne eller gj.øre den halvfaste tannpleiemiddelmasse flytende for å kunne ekstrudere denne. Dette har tidligere ikke vært et vesentlig problem fordi oppskrifter kan reguleres for anvendelse av mindre gelmiddel slik at det fåes en balanse mellom at tannpleiemidlet ikke skal være for mykt ved begynnelsen av anvendelsen av dette og ikke skal være for tykt ved slutten av anvendelsen av dette, og i ethvert tilfelle har brukerne lett vent seg til å påføre det trykk som er nødvendig for å ekstrudere den ønskede mengde av tannpleiemiddel på busten til en tannbørste. becoming thick, may become increasingly difficult for the user to extrude from a dentifrice tube over time. In other words, the user must increase the pressure against a dentifrice tube containing such a dentifrice during the period of its use in order to soften or liquefy the semi-solid dentifrice mass in order to be able to extrude it. This has not previously been a significant problem because recipes can be adjusted for the use of less gel agent so that a balance is achieved between the dental care agent not being too soft at the beginning of its use and not being too thick at the end of its use, and in any event, users have easily become accustomed to applying the pressure necessary to extrude the desired amount of dentifrice onto the bristles of a toothbrush.
Tannpleiemidler som er tynne når de ekstruderes fra Dentifrices that are thin when extruded
en tube, er også blitt akseptert under bruk av tannpleiemidlene dersom de størkner til en mer fast form på tannbørste-busten i løpet av noen få sekunder. Gelmiddeltypen vil således kunne varieres sterkt for tannpleiemidler som er emballert i tuber. Det er i virkeligheten blitt foreslått å anvende produktet "Genuvisco Type 0819" som er et iota-carragenan (i-carragenan), som et mulig fortykningsmiddel for tannpastaer. a tube, has also been accepted during use of the dental care products if they solidify into a more solid form on the toothbrush bristles within a few seconds. The type of gel agent can thus be varied greatly for dental care products that are packaged in tubes. It has actually been proposed to use the product "Genuvisco Type 0819" which is an iota-carrageenan (i-carrageenan) as a possible thickener for toothpastes.
I-carragenan som selges under varemerket "Viscarin TP-5", I-carrageenan sold under the trade name "Viscarin TP-5",
er også blitt foreslått for mulig anvendelse i tannpastaer når disse inneholder dikalsiumfosfater eller siliciumdioxyd. Dessuten er i-carragenan blitt beskrevet som en fortykkende komponent sammen med k-carragenan og alkalimetallalginat i et tannpleiemiddel som inneholder galactangalactose, ifølge japansk patentpublikasjon 56 115711, publisert 11. september 1981. has also been suggested for possible use in toothpastes when these contain dicalcium phosphates or silicon dioxide. Also, i-carrageenan has been described as a thickening component together with k-carrageenan and alkali metal alginate in a dentifrice containing galactangalactose, according to Japanese Patent Publication 56 115711, published on September 11, 1981.
Når en tannpleiemiddelutmatningsanordning som betjenes mekanisk eller ved trykkforskjell anvendes, kan det hende at vanlige metoder for å nedsette fortykningen av tannpleiemidler ikke er helt tilfredsstillende fordi sammenlignet med et tannpleiemiddel som er fylt i en fleksibel tube, må tannpleiemidlet når en utmatningsanordning anvendes, være forholdsvis tynt under ifyllingen, men gjenvinne sin konsistens og bevare denne under transport, lagring og bruk. Med andre ord gjen-vinner tannpleiemidlet etter ifylling i det vesentlige den konsistens som det hadde før flytendegjøringsvirkningen under ifyllingen under innvirkning av skjærkraft for transport, lagring og bruk. Vanlige gelmidler, som natriumcarboxymethylcellulose, hydroxyethylcellulose eller blandinger derav, When a dentifrice dispensing device operated mechanically or by pressure difference is used, it may be that common methods of reducing the thickening of dentifrices are not entirely satisfactory because compared to a dentifrice which is filled in a flexible tube, the dentifrice when a dispensing device is used must be relatively thin during filling, but regain its consistency and preserve this during transport, storage and use. In other words, the dentifrice after filling essentially regains the consistency it had before the liquefaction effect during filling under the influence of shear force for transport, storage and use. Common gelling agents, such as sodium carboxymethylcellulose, hydroxyethylcellulose or mixtures thereof,
kan med fordel anvendes for tannpleiemidler som inneholder ot-aluminiumoxydtrihydrat som poleringsmiddel og som skal fylles i en utmatningsanordning. Når imidlertid et slikt tannpleiemiddel inneholder flere utgangsmaterialer for aktive bestanddeler, som minst to utgangsmaterialer for fluor, et desensibiliseringsmiddel, som allantoin (C^HgN^O^) , og et vasodilatorisk middel, som pyridylcarbinol, can be advantageously used for dental care products that contain ot-aluminium oxide trihydrate as a polishing agent and which are to be filled in a dispensing device. However, when such a dentifrice contains several starting materials for active ingredients, such as at least two starting materials for fluoride, a desensitizing agent, such as allantoin (C^HgN^O^), and a vasodilatory agent, such as pyridylcarbinol,
oppstår vanskeligheter når tannpleiemidlet fylles i en mekanisk betjent utmatningsanordning eller en trykkforskjellsutmatningsanordning . Spesielt kan tannpleiemidlet sive ut gjennom rommet mellom en stav og et stempel som anvendes spesielt i en mekanisk betjent utmatningsanordning, og lekkasje forekommer ved utmatningsanordningens åpninger. Dessuten kan det tannpleiemiddelbånd som ekstruderes fra en mekanisk betjent utmatningsanordning eller trykkforskjellsutmatningsanordning, være ujevnt eller ikke-kontinuerlig. Da det er spesielt ønskelig å fremstille et tannpleiemiddel som inneholder a-aluminiumoxydtrihydratpoleringsmiddel og som inneholder flere aktive midler, som dem som er nevnt ovenfor, var det på grunn av forlikeligheten mellom slike materialer og poleringsmidlet nødvendig med et alternativt gelsystem. difficulties arise when the dentifrice is filled into a mechanically operated dispensing device or a pressure differential dispensing device. In particular, the dental care agent can seep out through the space between a rod and a piston which is used in particular in a mechanically operated dispensing device, and leakage occurs at the dispensing device's openings. Also, the dentifrice strip extruded from a mechanically operated or differential pressure dispenser may be uneven or non-continuous. As it is particularly desirable to produce a dentifrice which contains α-aluminium oxide trihydrate polishing agent and which contains several active agents, such as those mentioned above, due to the compatibility between such materials and the polishing agent, an alternative gel system was necessary.
Blant de alternative typer av gelmidler var det over-raskende at en blanding av et cellulosegelmiddel og i-carragenan gir et utmerket tannpleiemiddel som inneholder a-aluminiumoxydtrihydrat og flere aktive bestanddeler og som skal fylles i og ekstruderes fra en mekanisk utmatningsanordning eller trykkforskjellsutmatningsanordning. Det er bemerkelses-verdig at xanthan ikke har vært forlikelig med cellulose-..... gelmidler fordi det kan inneholdes cellulase. Among the alternative types of gelling agents, it was surprising that a mixture of a cellulose gelling agent and i-carrageenan provides an excellent dentifrice containing α-aluminum oxide trihydrate and several active ingredients and to be filled in and extruded from a mechanical dispensing device or pressure difference dispensing device. It is noteworthy that xanthan has not been compatible with cellulose... gelling agents because it may contain cellulase.
Det er en fordel ved den foreliggende oppfinnelse at det ved denne tilveiebringes et tannpleiemiddel som lett kan fylles i og ekstruderes fra en mekanisk betjent utmatningsanordning eller en trykkforskjellsutmatningsanordning for tannpleiemidler. It is an advantage of the present invention that it provides a dental care agent which can be easily filled in and extruded from a mechanically operated dispensing device or a pressure difference dispensing device for dental care agents.
Oppfinnelsen angår således et tannpleiemiddel i en mekanisk betjent utmatningsanordning eller trykkforskjellsutmatningsanordning, og tannpleiemidlet er særpreget ved at det omfatter 20-80 vekt% av en vandig fuktighetsbevarende bærer, 0,1-5 vekt% av en gelmiddelblanding, 20 - 75 vekt% a-aluminiumoxydtrihydrat som poleringsmiddel, natriumfluorid og natriummonofluorfosfat i en mengde tilstrekkelig til å gi 300 - 10.000 ppm fluor, 0,05 - 0,5 vekt% allantoin som desensibiliseringsmiddel og 0,05 - 0,5 vekt% pyridylcarbinol, idet gelmiddelblandingen utgjøres av en blanding av et cellulosegelmiddel eller xanthan og i-carragenan i et vektforhold av cellulosegelmiddel eller xanthan til i-carragenan av 5:1 - 1:5. The invention thus relates to a dental care agent in a mechanically operated dispensing device or pressure difference dispensing device, and the dental care agent is characterized by the fact that it comprises 20-80% by weight of an aqueous moisture-preserving carrier, 0.1-5% by weight of a gel agent mixture, 20-75% by weight a- aluminum oxide trihydrate as a polishing agent, sodium fluoride and sodium monofluorophosphate in an amount sufficient to provide 300 - 10,000 ppm fluorine, 0.05 - 0.5% by weight allantoin as a desensitizing agent and 0.05 - 0.5% by weight pyridylcarbinol, the gelling agent mixture consisting of a mixture of a cellulose gelling agent or xanthan and i-carrageenan in a weight ratio of cellulose gelling agent or xanthan to i-carrageenan of 5:1 - 1:5.
I tannpleiemidlet omfatter tannpleiemiddelbæreren en flytende fase som er mengdeavpasset i forhold til gelmidlet slik at det fåes en ekstruderbar, kremlignende masse med ønsket konsistens. Den flytende fase i tannpleiemidlet vil hovedsakelig utgjøres av vann og et fuktighetsbevarende middel, som polyoler, innbefattende glycerol, sorbitol, maltitol, xylitol, lavmolekylær polyethylenglycol (f.eks. molekylvekt 400 eller 600), propylenglycol eller et lignende fuktighetsbevarende middel, innbefattende egnede blandinger av disse. Det er som regel fordelaktig som den flytende fase å anvende vann og et fuktighetsbevarende middel som glycerol, sorbitol eller polyethylenglycol, typisk i mengder av 10 - 55 vekt% vann og 20 - 50 vekt% fuktighetsbevarende middel. In the dentifrice, the dentifrice carrier comprises a liquid phase whose quantity is adjusted in relation to the gel agent so that an extrudable, cream-like mass with the desired consistency is obtained. The liquid phase in the dentifrice will mainly consist of water and a humectant, such as polyols, including glycerol, sorbitol, maltitol, xylitol, low molecular weight polyethylene glycol (e.g. molecular weight 400 or 600), propylene glycol or a similar humectant, including suitable mixtures of these. It is generally advantageous as the liquid phase to use water and a humectant such as glycerol, sorbitol or polyethylene glycol, typically in amounts of 10-55% by weight of water and 20-50% by weight of humectant.
Tannpleiemidlet inneholder a-aluminiumoxydtrihydrat The toothpaste contains α-aluminium oxide trihydrate
som poleringsmiddel i en mengde av 20 - 75 vekt%. a-aluminium- as a polishing agent in an amount of 20 - 75% by weight. a-aluminum-
oxydtrihydrat blir typisk fremstilt ved Bayer-prosessen og anvendt som partikler med en størrelse under 4 0 jam, hovedsakelig med en størrelse av 3 - 20 pm. Andre poleringsmidler kan være tilstede, som uoppløselig natriummetafosfat, dikalsic fosfat, kalsinert aluminiumoxyd, siliciumdioxyd eller kalsium-carbonat, i mindre mengder i forhold til a-aluminiumoxydtrihydrat . oxide trihydrate is typically prepared by the Bayer process and used as particles with a size below 40 µm, mainly with a size of 3 - 20 µm. Other polishing agents may be present, such as insoluble sodium metaphosphate, dicalcic phosphate, calcined aluminum oxide, silicon dioxide or calcium carbonate, in smaller amounts compared to α-aluminium oxide trihydrate.
Gelmiddelblandingen i tannpleiemidlene ifølge oppfinnelsen er tilstede i en mengde av 0,1 - 5 vekt%. Den inneholder et cellulosegelmiddel eller xanthan blandet med i-carragenan i et vektforhold mellom cellulosegelmidlet eller xanthanet og i-carragenanet av 5:1 - 1:5, fortrinnsvis 1:1 - 1:3, og den samlede gelmiddelblandingsmengde er fortrinnsvis 0,2-3 vekt%. The gel agent mixture in the dental care products according to the invention is present in an amount of 0.1 - 5% by weight. It contains a cellulose gelling agent or xanthan mixed with i-carrageenan in a weight ratio between the cellulose gelling agent or the xanthan and the i-carrageenan of 5:1 - 1:5, preferably 1:1 - 1:3, and the total amount of gelling agent mixture is preferably 0.2- 3% by weight.
Som nevnt ovenfor, er iota-carragenan tilgjengelig i handelen som "Genuvisco Type 0819" ogViscarin TP-5" og er blitt anbefalt for anvendelse i en tannpasta. En slik anvendelse i en tannpasta er beskrevet i japansk patentpublikasjon 56 115711, hvor i-carragenan er nevnt som en mulig bestanddel i et gelsystem sammen med k-carragenan og alkalimetallalginat. I US patent 4 353 890 er i-carragenan beskrevet som et alternativ til k-carragenan som et tannpasta-gelmiddel hvor tannpastaen utsettes for mikrobølgebestråling for å redusere carragenans generelle tilbøyelighet til å As mentioned above, iota-carrageenan is commercially available as "Genuvisco Type 0819" and Viscarin TP-5" and has been recommended for use in a toothpaste. Such use in a toothpaste is disclosed in Japanese Patent Publication 56 115711, wherein i-carrageenan is mentioned as a possible component in a gel system together with k-carrageenan and alkali metal alginate. In US patent 4,353,890, i-carrageenan is described as an alternative to k-carrageenan as a toothpaste gelling agent where the toothpaste is exposed to microwave irradiation to reduce the carrageenan's general inclination to
bli tynt under fremstillingen. Carragenanet kan være det eneste gelmiddel eller anvendes i blanding med andre gelmidler. Tannpleiemidlet ifølge oppfinnelsen som inneholder i-carragenan og som skal fylles i en mekanisk betjent utmatningsanordning eller trykkforskjellsutmatningsanordning, behøver ikke å utsettes for mikrobølgebestråling. become thin during preparation. The carrageenan can be the only gelling agent or used in a mixture with other gelling agents. The toothpaste according to the invention which contains i-carrageenan and which is to be filled in a mechanically operated dispensing device or pressure difference dispensing device, does not need to be exposed to microwave radiation.
Den teknikkens stand som er generelt omtalt ovenfor, antyder ikke at gelsystemer av cellulosegelmiddel og i-carragenan kan gi tannpleiemidler som inneholder a-aluminiumoxydtrihydrat som poleringsmiddel og en rekke aktive bestanddeler, slik at tannpleiemidlene får de egenskaper som er nødvendige for effektivt å kunne fylles i mekanisk betjente utmatningsanordninger eller trykkforskjellsutmatningsanord-ninger og ekstruderes fra disse. The state of the art which is generally discussed above does not suggest that gel systems of cellulose gel agent and i-carrageenan can provide dentifrices containing α-aluminium oxide trihydrate as a polishing agent and a number of active ingredients, so that the dentifrices acquire the properties necessary to be effectively filled in mechanically operated discharge devices or pressure difference discharge devices and are extruded from these.
Det bør bemerkes at i US patent 4 029 760 er et munn-pleiemiddel beskrevet hvori i-carragenin er angitt som et alternativt antigingivittmiddel til andre carrageniner. Carrageniner er sterkt avpolymeriserte derivater av carragenaner. Carragenaner synes ikke å gi en antigingivittvirk-ning. It should be noted that in US patent 4,029,760 an oral care agent is described in which i-carrageenan is indicated as an alternative antigingivitis agent to other carrageenins. Carrageenins are highly depolymerized derivatives of carrageenans. Carrageenans do not seem to have an antigingivitis effect.
Tannpleiemidler blir vanligvis fremstilt ved en kaldprosess, f.eks. ved ca. 25°C, eller ved en varmprosess, f.eks. ved ca. 60°C. I-carragenan kan anvendes ved kaldprosess-eller varmprosessmetodene. Da xanthan fremstilles ved kaldbehandling når xanthan anvendes, kan dette lett blandes med i-carragenan og innarbeides sammen med dette i tannpleiemidlet ved kaldbehandling. I-carragenan kan anvendes bare ved varmbehandling. Tooth care products are usually produced by a cold process, e.g. at approx. 25°C, or by a hot process, e.g. at approx. 60°C. I-carrageenan can be used by cold process or hot process methods. As xanthan is produced by cold processing when xanthan is used, this can easily be mixed with i-carrageenan and incorporated together with this in the dental care product by cold processing. I-carrageenan can only be used with heat treatment.

Typiske ønskede cellulosegelmidler innbefatter alkali-metallcarboxymethylcellulose, methylcellulose, hydroxymethyl-cellulose eller hydroxypropylcellulose. Natriumcarboxymethylcellulose er foretrukken. Det blandede gelsystem er tilstede i en mengde av 0,1 - 5 vekt% av tannpleiemidlet, og vektforholdet mellom cellulosegelmiddel og i-carragenan er 5:1 - 1:5, fortrinnsvis 1:1 - 1:3, og mest foretrukket ca. 1:1. Typical desired cellulosic gelling agents include alkali metal carboxymethylcellulose, methylcellulose, hydroxymethylcellulose or hydroxypropylcellulose. Sodium carboxymethylcellulose is preferred. The mixed gel system is present in an amount of 0.1 - 5% by weight of the dental care agent, and the weight ratio between cellulose gel agent and i-carrageenan is 5:1 - 1:5, preferably 1:1 - 1:3, and most preferably approx. 1:1.
Et typisk foretrukket tannpleiemiddel kan således inneholde en samlet gelmiddelmengde av 0,9 - 1,2%, innbefattende 0,3 - 0,9% av såvel cellulosegelmiddel som i-carragenan, idet vektforholdet mellom disse to er 1:1 - 1:3. A typical preferred dental care product can thus contain a total amount of gelling agent of 0.9 - 1.2%, including 0.3 - 0.9% of both cellulose gelling agent and i-carrageenan, the weight ratio between these two being 1:1 - 1:3 .
Det bør bemerkes at kvaliteter av natriumcarboxymethylcellulose som kan anvendes, innbefatter de følgende: It should be noted that grades of sodium carboxymethylcellulose which may be used include the following:
Dessuten innbefatter anvendbare kvaliteter av hydroxyethylcellulose de følgende: Additionally, useful grades of hydroxyethyl cellulose include the following:
Cellulosegelmidlet og i-carragenanet kan blandes mekanisk med hverandre før de blandes med den flytende fase i tannkrembæreren eller de kan blandes separat med den flytende fase under anvendelse av varmproduksjons (typisk ca. 60°C)-eller kaldproduksjons (typisk ca. 25°C)-metoder. The cellulose gelling agent and the i-carrageenan can be mechanically mixed with each other before being mixed with the liquid phase in the toothpaste carrier or they can be mixed separately with the liquid phase using hot production (typically about 60°C) or cold production (typically about 25°C ) methods.
Xanthangurrurii er et gjæringsprodukt fremstilt ved innvirkning av bakteriene av slekten Xanthomonas på kullhydrater. Fire arter av Xanthomonas, dvs. X campetris, X phaseoli, X ^malvocearum og X carotae, er i litteraturen blitt angitt å være de mest effektive gummiprodusenter. Selv om den nøyaktige kjemiske struktur ikke er blitt fastslått, er det generelt akseptert at den er et heteropolysaccharid med en molekylvekt av flere millioner. De inneholder D-glucose, D-mannose og D-glucoronsyre i molforholdet 2,8:3:2. Molekylet inneholder 4,7% acetyl og ca. 3% pyruvat. Den foreslåtte kjemiske struktur finnes i McNeely og Kang, Industrial Gums, red. Xanthangurrurii is a fermentation product produced by the action of the bacteria of the genus Xanthomonas on carbohydrates. Four species of Xanthomonas, ie X campetris, X phaseoli, X ^malvocearum and X carotae, have been reported in the literature to be the most efficient rubber producers. Although its exact chemical structure has not been determined, it is generally accepted that it is a heteropolysaccharide with a molecular weight of several million. They contain D-glucose, D-mannose and D-glucoronic acid in the molar ratio 2.8:3:2. The molecule contains 4.7% acetyl and approx. 3% pyruvate. The proposed chemical structure is found in McNeely and Kang, Industrial Gums, ed.

Ytterligere beskrivelse av xanthan-gummi finnes i Manufacturing Chemist, mai 1960, s. 206 - 208 (innbefattende omtale på side 208 av potensiell anvendelse av gummier som er beskrevet i denne publikasjon, for fremstilling av tannpastaer). R. L. Whistler, CH XXL, 2nd edition, New York, 1973. The method for extracting, isolating and purifying the xanthan gum is also found in this publication. Further description of xanthan gum can be found in Manufacturing Chemist, May 1960, pp. 206-208 (including discussion on page 208 of the potential use of gums described in this publication for the manufacture of toothpastes).
Xanthanet og i-carragenanet kan blandes mekanisk med hverandre før de blandes med den flytende fase av tannkrembæreren eller de kan blandes separat med den flytende fase ved hjelp av kaldproduksjons (typisk ca. 25°C)-metoder. The xanthan and i-carrageenan can be mechanically mixed with each other before mixing with the liquid phase of the toothpaste carrier or they can be mixed separately with the liquid phase using cold production (typically about 25°C) methods.
Tannpleiemidlet pakkes i en beholder hvorfra det lett kan ekstruderes, f.eks. en trykkforskjellsutmatningsanordning eller en mekanisk betjent utmatningsanordning for tannkrem. The toothpaste is packaged in a container from which it can be easily extruded, e.g. a differential pressure dispensing device or a mechanically operated toothpaste dispensing device.
De rheologiske egenskaper er sterkt ønskede når en mekanisk betjent utmatningsbeholder av den type som er beskrevet i britisk patentsøknad 2 070 695A, publisert 9. september 1981, anvendes. Utmatningsbeholderen omfatter et utmatnihgsmunnstykke, et strekkelement, en sentral stav, et stempel og en håndbe-tjeningsinnretning. The rheological properties are highly desirable when a mechanically operated discharge container of the type described in British Patent Application 2,070,695A, published September 9, 1981, is used. The dispensing container comprises a dispensing nozzle, a tension element, a central rod, a piston and a manual operating device.

Når f.eks. en mekanisk betjent utmatningsanordning av den type som er beskrevet i den publiserte- britiske patentsøknad 2 070 695A anvendes, blir en på forhånd bestemt mengde av tannpleiemidlet ekstrudert;gjennom et munnstykke for å fylle utmatningsanordningen som er åpen ved sin bunn og inneholder en sentral stav. Et stempel med en diameter som svarer til utmatningsanordningens innvendige diameter og som har et sentralt hull for at den sentrale stav kan innføres i dette, får gli på plass. Utmatningsanordningen blir deretter lukket medl en bunnskive. When e.g. a mechanically operated dispensing device of the type described in published British patent application 2 070 695A is used, a predetermined quantity of the dentifrice is extruded through a nozzle to fill the dispensing device which is open at its bottom and contains a central rod. A piston with a diameter corresponding to the inside diameter of the dispensing device and having a central hole for the central rod to be inserted therein is allowed to slide into place. The dispensing device is then closed with a bottom disc.
