Teknikkens stand State of the art
Sammenfoldbare tuber av metall eller plaster har lenge vært kjent innen emballasjeområdet. Ekstruderte metalltuber er sprø som sådanne, og gjentatt anvendelse fører ganske ofte til sprekkdannelse i veggene slik at produktet utsondres fra et annet sted enn utmatningsåpningen som er i det vesentlige stiv. Blant kjente metalltuber har aluminium-tuber selv om disse trolig er de minst.skjøre, hatt en noe begrenset anvendelse fordi det hittil ikke har vært mulig på slike tubers innvendige overflate å påføre et fullstendig tilfredsstillende belegg dersom dette er nødvendig for å •hindre angrep og korrosjon av metallet på grunn av et alkalisk eller surt innhold og forurensning av innholdet på grunn av reaksjonsproduktene. Uaktet en metalltubes forholdsvis skjøre art krever den nevnte innvendige belegning et ytterligere behandlingstrinn som nødvendigvis øker prisen for slutt-gjenstanden. Collapsible tubes made of metal or plastic have long been known in the field of packaging. Extruded metal tubes are brittle as such, and repeated use quite often leads to cracking of the walls so that the product is secreted from a place other than the discharge opening which is essentially rigid. Among known metal tubes, aluminum tubes, even though these are probably the least fragile, have had a somewhat limited use because it has not been possible until now to apply a completely satisfactory coating to the inner surface of such tubes if this is necessary to •prevent attack and corrosion of the metal due to an alkaline or acidic content and contamination of the content due to the reaction products. Notwithstanding the relatively fragile nature of a metal tube, the aforementioned internal coating requires a further processing step which necessarily increases the price of the final object.
Tuber av polyethylen og andre plastmaterialer har hatt utstrakt kommersiell suksess for emballering av en rekke produkter. Imidlertid er det blitt notert at visse andre produkter efter en viss tid forringes når de inneholdes i slike tuber. Plaster, f.eks. polyethylen, er gjennom-trengelige i en viss grad når de anvendes med de; vegg-tykkelsersom er vanlige for rørformige beholdere, og de etheriske oljer som anvendes i de fleste tannpleiemidler Tubes made of polyethylene and other plastic materials have had widespread commercial success for packaging a variety of products. However, it has been noted that certain other products deteriorate over time when contained in such tubes. Plasters, e.g. polyethylene, are permeable to a certain extent when used with those; wall thicknesses that are common for tubular containers, and the essential oils used in most dentifrices
for å sette smak på disse, får redusert volum under lagring av beholderen og gjør at tannpleiemidlet blir mindre vel-smakende. Dessuten absorberer plastbeholderveggen oxygen med tiden, og dette kan til slutt føre til at produktet blir spaltet,hvilket i virkeligheten har vist seg å være tilfellet for fluoridholdige tannpastaer. to add flavor to these, gets a reduced volume during storage of the container and makes the toothpaste less good-tasting. Also, the plastic container wall absorbs oxygen over time, and this can eventually cause the product to decompose, which in reality has been shown to be the case with fluoride toothpastes.
Det er derfor blitt foreslått å tilveiebringe en forholdsvis tynn barriere av en metallfolie mellom produktet og polyethylentubelegemet for å hindre det nevnte tap av etheriske oljer og absorpsjonen av oxygen. Metallbarrieren er blitt foreslått som et mellomlag mellom mot hverandre anordnede ark av polyethylen, og det er blitt foreslått at et laminat kan dannes ved innvirkning av varme med eller uten egnede klebemidler. Selv om imidlertid en oppbygning av denne generelle art effektivt vil hindre endel gjennomtrengning av produktet og absorpsjon av oxygen gjennom rør-legemet, og spesielt når- det innvendige termoplastlag består av en copolymer av et olefin og en monomer som inneholder en polar gruppe og som lar seg copolymerisere med dette,er mulig-heten fremdeles tilstede for at produktet vil forringes om enn i en langt mindre grad. It has therefore been proposed to provide a relatively thin barrier of a metal foil between the product and the polyethylene tube body to prevent the aforementioned loss of essential oils and the absorption of oxygen. The metal barrier has been proposed as an intermediate layer between mutually arranged sheets of polyethylene, and it has been proposed that a laminate can be formed by the action of heat with or without suitable adhesives. Although, however, a structure of this general nature will effectively prevent complete penetration of the product and absorption of oxygen through the tube body, and especially when the inner thermoplastic layer consists of a copolymer of an olefin and a monomer containing a polar group and which allows copolymerize with this, the possibility is still present that the product will deteriorate, albeit to a much lesser extent.
Det er en ulempe ved en polyolefinoverflate at denne ikke er istand til lett å bli trykket eller bli påført et dekorasjonsmateriale. Dessuten har polyolefin en hukommelses-virkning, dvs. at det ikke holder seg sammentrykket når det klemmes sammen, og dette er en spesiell ulempe ved tannpleie-middeltuber. For å motvirke en slik manglende sammentrykkbarhet må metallaget være forholdsvis tykt slik at metall-lagets sammentrykkbarhet påtvinges plasten. A disadvantage of a polyolefin surface is that it is not capable of being easily printed or applied to a decorative material. In addition, polyolefin has a memory effect, i.e. that it does not retain its compression when squeezed together, and this is a particular disadvantage of dental care product tubes. In order to counteract such a lack of compressibility, the metal layer must be relatively thick so that the compressibility of the metal layer is imposed on the plastic.
Oppsummering av oppfinnelsen Summary of the invention
Det tas derfor ved oppfinnelsen sikte på å tilveiebringe et laminat til bruk i en sammenfoldbar beholder for utmatning av viskøse produkter. The invention therefore aims to provide a laminate for use in a collapsible container for dispensing viscous products.
En slik beholder vil ofte være rørformig med en rekke vedhengende lag i dens. kroppsdel, idet ett av lagene, Such a container will often be tubular with a number of attached layers within it. body part, being one of the layers,
f.eks. en metallfolie, danner en barriere mot migrering av produkt og absorpsjon av oxygen, og et annet av lagene består av et polyalkylenmateriale fra gruppen bestående av polyethylenterefthalat og polybutylenterefthalat eller en kopolymer med en mindre mengde av en annen dicarboxylsyre med varierende densitet, smeltepunkt og krystallinitet. Det sistnevnte lag befinner seg innerst og fortrinnsvis ytterst med forskjellige ytterligere laminerte lag klemt inn mellom disse. e.g. a metal foil, forms a barrier against migration of product and absorption of oxygen, and another of the layers consists of a polyalkylene material from the group consisting of polyethylene terephthalate and polybutylene terephthalate or a copolymer with a smaller amount of another dicarboxylic acid with varying density, melting point and crystallinity. The latter layer is located at the innermost and preferably at the outermost with various further laminated layers sandwiched between them.
Slike ytterligere lag omfatter papir og egnede klebemidler og bindemidler, som kopolymerer av ethylen og acrylsyre. Such additional layers include paper and suitable adhesives and binders, such as copolymers of ethylene and acrylic acid.
Oppfinnelsen angår således et laminat til bruk i sammenfoldbar beholder for utmatning av viskøse produkter, The invention thus relates to a laminate for use in a collapsible container for dispensing viscous products,
og laminatet er særpreget ved at det omfatter et første lag av en polyester, et annet lag av metallfolie, et tredje lag av papir og et fjerde lag av en polyester. and the laminate is distinctive in that it comprises a first layer of a polyester, a second layer of metal foil, a third layer of paper and a fourth layer of a polyester.
Laminatet ifølge oppfinnelsen kan anvendes for frem-stilling av en sammenfoldbar utmatningsbeholder ved hjelp av vanlige og kjente apparater. Eksempler på et slikt ut-styr og en slik fremgangsmåte er angitt i US patent 3832964. The laminate according to the invention can be used for the production of a collapsible dispensing container using common and known devices. Examples of such equipment and such a method are indicated in US patent 3832964.
Tuber av laminatene ifølge oppfinnelsen kan fremstilles ved at et rørformig legeme formes fra et barrierelag og en polyester laminert til dette. Det laminerte rørlegeme blir derefter anbragt på en formdel tilstøtende til en barriere-del som også er anbragt på denne. Tubes of the laminates according to the invention can be produced by forming a tubular body from a barrier layer and a polyester laminated to this. The laminated pipe body is then placed on a form part adjacent to a barrier part which is also placed on this.

Metallfolien kan fortrinnsvis utgjøres av en aluminiumfolie, og papirlaget kan med fordel bestå av kraftpapir. The metal foil can preferably consist of an aluminum foil, and the paper layer can advantageously consist of kraft paper.
Tykkelsesområdet for hvert av lagene er som følger: Polyethylenterefthalatlaget 11: 0,0127-0,0762 mm, fortrinnsvis 0,0254 mm. The thickness range for each of the layers is as follows: Polyethylene terephthalate layer 11: 0.0127-0.0762 mm, preferably 0.0254 mm.
Klebemiddellaget 12: tilstrekkelig til å sikre ved-hengning. Adhesive layer 12: sufficient to ensure adhesion.
Metallfolielaget 13: 0,0127-0,0508 mm, fortrinnsvis 0,0254 mm. The metal foil layer 13: 0.0127-0.0508 mm, preferably 0.0254 mm.
Klebemiddellaget 14: tilstrekkelig til å sikre ved-he ngning. Adhesive layer 14: sufficient to ensure adhesion.
Papirlaget 15: 0,0 381-0,06 35 mm, fortrinnsvis 0,0508 mm. Paper layer 15: 0.0 381-0.06 35 mm, preferably 0.0508 mm.

På Fig. 2 er et eksempel på den laminerte oppbygning av en sammenfoldbar beholder vist ved de lag som er vist på Fig. 1, idet laget 11 utgjør det innerste lag og de øvrige lag består av de samme materialer og i den samme rekkefølge som vist. In Fig. 2, an example of the laminated structure of a collapsible container is shown by the layers shown in Fig. 1, with layer 11 constituting the innermost layer and the other layers consisting of the same materials and in the same order as shown .
Det fremgår av det ovenstående at det ved oppfinnelsen er blitt tilveiebragt en sammenfoldbar beholder med en oppbygning som sterkt reduserer de problemer som hittil ikke er blitt løst i henhold til teknikkens stand. Laminatet og det laminerte skulderstykke 20 virker slik at en gjennomtrengning av produktet og absorpsjon av oxygen unngås fullstendig, og dette sterkt ønskede resultat oppnås ved anvendelse av rimelige materialer som fortrinnsvis er kombinert under dannelse av den laminattype som er antydet på Fig. 2. It appears from the above that the invention has provided a collapsible container with a structure that greatly reduces the problems that have not been solved up to now according to the state of the art. The laminate and the laminated shoulder piece 20 act so that a penetration of the product and absorption of oxygen is completely avoided, and this highly desired result is achieved by the use of inexpensive materials which are preferably combined to form the type of laminate indicated in Fig. 2.
Det ytre lag av et polyethylenterefthalat er termo-plastisk og istand til sammensmelting når det utsettes for et sidesammenføyningstrinn, og til å gi tilstrekkelig beskyttelse for papiret og metallfoliemellomlaget. Måten for å sammenføye en sammenfoldbar tannpleiemiddeltube av den her beskrevne generelle type er beskrevet i US patent 3295725. The outer layer of a polyethylene terephthalate is thermoplastic and capable of fusing when subjected to a side joining step, and of providing adequate protection for the paper and metal foil interlayer. The method of joining a collapsible dentifrice tube of the general type described here is described in US patent 3295725.
Da det ytterste og innerste lag av laminatet ifølge oppfinnelsen fortrinnsvis er de samme, kan de brettede kanter av røret fremstilt fra laminatet bekvemt bindes sammen ved anvendelse av varme. Et egnet klebemiddel kan anvendes dersom sammenbinding ved hjelp av varme ikke er mulig. Denne modifikasjon kommer i tillegg til de ovennevnte fire-lags laminater som fra utsiden og innad omfatter polyalkylenterefthalat, papir, folie og polyalkylenterefthalat, eller polyalkylenterefthalat, folie, papir og polyalkylen-teref thalat. Det tas sikte på at egnede klebemidler vil bli anvendt mellom laminatlagene dersom dette skulle være nød-vendig. De samme oppbygninger kan anvendes for skulder-stykket, hetten, halsen, stangen,stemplet og ved fremstill-ing av utmatningsventiler for slike beholdere, spesielt i forbindelse med de innvendige deler som er utsatt for det inneholdte tannpleiemiddel, og igjen vil forlikelige klebemidler naturlig bli anvendt dersom dette skulle være nødvendig. As the outermost and innermost layers of the laminate according to the invention are preferably the same, the folded edges of the tube produced from the laminate can be conveniently bonded together by the application of heat. A suitable adhesive can be used if bonding using heat is not possible. This modification is in addition to the above-mentioned four-layer laminates which from the outside and inside comprise polyalkylene terephthalate, paper, foil and polyalkylene terephthalate, or polyalkylene terephthalate, foil, paper and polyalkylene terephthalate. It is intended that suitable adhesives will be used between the laminate layers should this be necessary. The same constructions can be used for the shoulder piece, the cap, the neck, the rod, the piston and in the production of discharge valves for such containers, especially in connection with the internal parts which are exposed to the contained dentifrice, and again compatible adhesives will naturally be applied if this should be necessary.
Forskjellige utføreIsesformer av oppfinnelsen er her blitt beskrevet, og disse og andre forandringer kan selv-følgelig utføres uten at dette avviker fra de nye erkjennelser som det her bidras med. Når dessuten materialet er støpt i form av en film på de innvendige overflater av fiberfat som anvendes for lagring av smaksmiddeltilsatte tannpleiemidler, vil materialet forsinke tap av smak inn i fatene, hvorved lagringslevealderen forlenges. Various embodiments of the invention have been described here, and these and other changes can of course be made without this deviating from the new findings that are contributed here. Furthermore, when the material is cast in the form of a film on the inner surfaces of fiber barrels used for the storage of flavored dental care products, the material will delay the loss of flavor into the barrels, thereby extending the storage life.
Polyethylenterefthalatet (PET) er spesielt gunstig fordi det har en meget lav absorpsjon av smak, hvilket fremgår av de nedenstående tabeller hvor PET er sammenlignet med polyethylen og hvor tykkelsene av lag eller belegg er de samme: The polyethylene terephthalate (PET) is particularly beneficial because it has a very low absorption of taste, which is evident from the tables below where PET is compared with polyethylene and where the thicknesses of layers or coatings are the same:
