Description
463 868 Det har sålunda föreslagits att anordna en relativt tunn metallfoliebarriär mellan produkten och poly- etentubkroppen för att förhindra nämnda förlust av essentiella oljor och syreabsorption. Metallbarriären har föreslagits som ett mellanskikt mellan utåtvända skikt av polyeten och att ett laminat värmeformas med eller utan lämpliga bindemedel. Emellertid, även om en struktur med denna allmänna uppbyggnad effektivt förhindrar viss produktgenomträngning och syreabsorption genom tubkroppen, och särskilt när det inre termoplast- iska skiktet är en sampolymer av en olefin och en monomer innehållande en polär grupp, vilken är sampolymeriserbar därmed, kvarstår möjligheten till produktförsämring om än i väsentligt mindre utsträckning. Thus, it has been proposed to provide a relatively thin metal foil barrier between the product and the polyethylene tube body to prevent said loss of essential oils and oxygen absorption. The metal barrier has been proposed as an intermediate layer between outwardly facing layers of polyethylene and that a laminate is thermoformed with or without suitable adhesives. However, although a structure of this general structure effectively prevents some product penetration and oxygen absorption through the tube body, and especially when the inner thermoplastic layer is a copolymer of an olefin and a monomer containing a polar group which is copolymerizable therewith, the possibility of product deterioration, albeit to a significantly lesser extent.
En nackdel med en polyolefinyta ligger i oförmågan hos ytan att lätt motta tryck- eller dekorativt material.A disadvantage of a polyolefin surface lies in the inability of the surface to easily receive print or decorative material.
Dessutom har polyolefin en minneseffekt, d v s den förblir inte sammanpressad efter sammantryckning, vilket är särskilt till nackdel vid tandkrämstuber. För att motverka en sådan brist med avseende på kompressibilitet måste metallskiktet vara relativt tjockt, så att dess kompressibilitet överföres på plasten. Ändamålet för föreliggande uppfinning är att undvika ovan- nämnda olägenheter vid en inledningsvis beskriven be- hållare.In addition, polyolefin has a memory effect, i.e. it does not remain compressed after compression, which is particularly disadvantageous in toothpaste tubes. To counteract such a deficiency in compressibility, the metal layer must be relatively thick, so that its compressibility is transferred to the plastic. The object of the present invention is to avoid the above-mentioned inconveniences of an initially described container.
Detta uppnås enligt uppfinningen vid en sådan behållare genom att ett innersta skikt av polyester, som är bundet till metallfolieskiktet, varvid polyestern är polyalkylen- tereftalat. Härvid kan lämpligen det innersta skiktet av polyestern vara säkrat vid metallfolien med ett bindemedel.This is achieved according to the invention in such a container by an innermost layer of polyester, which is bonded to the metal foil layer, the polyester being polyalkylene terephthalate. In this case, the innermost layer of the polyester can suitably be secured to the metal foil with a binder.
Ox 463 868 Övriga särdrag hos uppfinningen framgår av de i under- kraven angivna kännetecken.Ox 463 868 Other features of the invention appear from the features set forth in the subclaims.
Den hopfällbara behållaren enligt föreliggande uppfinning kan framställas med konventionell apparatur. Exempel på sådan utrustning och metod kan utläsas ur US patent 3 832 964, som skall anses utgöra en del av denna be- skrivning.The collapsible container of the present invention can be made with conventional apparatus. Examples of such equipment and methods can be found in U.S. Patent 3,832,964, which is incorporated herein by reference.
Uppfinningen kommer i det följande att beskrivas närmare i anslutning till bifogade ritning, på vilken Fig 1 är en tvärsnittsvy av en del av ett laminerat sub- strat enligt föreliggande uppfinning, och Fig 2 är en sidovy av en hopfällbar pastadispenseringsbe- hållare i enlighet med uppfinningen, med delar av kropps- väggarna bortbrutna för att mer fullständigt illustrera den laminerade strukturen.The invention will be described in more detail below with reference to the accompanying drawing, in which Fig. 1 is a cross-sectional view of a part of a laminated substrate according to the present invention, and Fig. 2 is a side view of a collapsible pasta dispensing container in accordance with the invention. , with parts of the body walls broken away to more fully illustrate the laminated structure.
Med hänvisning till fig 1 visas ett substrat 10 i tvärsnitt, för att därigenom åskådliggöra kompo- nenterna i sandwichstrukturen som utgör den laminerade konfigurationen.Referring to Fig. 1, a substrate 10 is shown in cross section, thereby illustrating the components of the sandwich structure constituting the laminated configuration.
Härav framgår att det understa skiktet 11 är en poly- ester. Det andra skiktet 12 ovanför är ett bindemedels- skikt, som förbinder polyesterskiktet 11 med det tredje skiktet 13 som är en metallfolie såsom en aluminiumfolie.From this it appears that the bottom layer 11 is a polyester. The second layer 12 above is an adhesive layer connecting the polyester layer 11 to the third layer 13 which is a metal foil such as an aluminum foil.
Det fjärde skiktet 14 är ett annat bindemedel som vid- häftande förbinder den andra ytan på metallfolieskiktet 13 till ett pappersskikt 15. Det översta skiktet 16 är en polyester. 463 868 Den termoplastiska polyestern enligt föreliggande upp- finning omfattar polyalkylentereftalat såsom polyetylen- tereftalat och polybutylentereftalat.The fourth layer 14 is another adhesive which adheres the second surface of the metal foil layer 13 to a paper layer 15. The top layer 16 is a polyester. 463 868 The thermoplastic polyester of the present invention comprises polyalkylene terephthalate such as polyethylene terephthalate and polybutylene terephthalate.
De användbara polyesterhartserna beskrives med avseende på behållaranvändning i US patent 3 152 515 och 4 197 326.The useful polyester resins are described with respect to container use in U.S. Patents 3,152,515 and 4,197,326.
Dessa patent beskriver exempelvis ett polyester-polyetylen- tereftalat. Dessa patent skall anses utgöra en del av föreliggande beskrivning.These patents describe, for example, a polyester-polyethylene terephthalate. These patents are to be considered as part of the present specification.
Inom ramen för uppfinningen kan bindemedlen vara en sampolymer av etylen och akrylsyra eller metakrylsyra, eller natrium- eller zinksalterna därav i ett lösnings- medelssystem.Within the scope of the invention, the binders may be a copolymer of ethylene and acrylic acid or methacrylic acid, or the sodium or zinc salts thereof in a solvent system.
Metallfolien kan företrädesvis vara aluminiumfolie.The metal foil may preferably be aluminum foil.
Pappersskiktet är lämpligen ett kraftpapper.The paper layer is suitably a kraft paper.
Tjockleksintervallet för vardera av skikten är följande: Polyetylentereftalatskiktet 11-0,0127 - 0,0762 mm, företrädesvis 0,0254 mm.The thickness range for each of the layers is as follows: The polyethylene terephthalate layer 11-0.0127 - 0.0762 mm, preferably 0.0254 mm.
Bindemedelsskiktet 12 - tillräckligt för att säker- ställa vidhäftning.Adhesive layer 12 - sufficient to ensure adhesion.
Metallfolieskiktet 13 - 0,0127 - 0,0508 mm, företrädes- vis 0,0254 mm.The metal foil layer 13 - 0.0127 - 0.0508 mm, preferably 0.0254 mm.
Bindemedelsskiktet 14 - tillräckligt för att säkerställa vidhäftning.The adhesive layer 14 - sufficient to ensure adhesion.
Pappersskiktet 15 - 0,0381 - 0,0635 mm, företrädes- vis 0,0508 mm.The paper layer 15 - 0.0381 - 0.0635 mm, preferably 0.0508 mm.
Polyetylentereftalatskiktet 16 - 0,0889 - 0,127 mm, företrädesvis O,1016 mm. 463 868 Det yttersta polyetylentereftalatskiktet 16 vidhäftar till pappersskiktet 15 genom pâläggning av tillräck- ligt värme och tryck till substratet. För den händelse påläggningen av värme och tryck inte är tillfyllest kan ett lämpligt bindemedel utnyttjas.The polyethylene terephthalate layer 16 - 0.0889 - 0.127 mm, preferably 0, 1016 mm. 463 868 The outermost polyethylene terephthalate layer 16 adheres to the paper layer 15 by applying sufficient heat and pressure to the substrate. In the event that the application of heat and pressure is not sufficient, a suitable binder can be used.
Fig 2 är ett exempel på den laminerade strukturen hos en hopfällbar behållare med de skikt som demonstreras i fig 1 med skiktet 11 innerst och de andra skikten framställda av samma material och i samma ordningsföljd som visas.Fig. 2 is an example of the laminated structure of a collapsible container with the layers demonstrated in Fig. 1 with the layer 11 at the bottom and the other layers made of the same material and in the same order as shown.
Såsom framgår ovan tillhandahålles en hopfällbar be- hâllarstruktur, som väsentligt reducerar de problem som hittills varit olösta enligt den kända tekniken.As can be seen above, a collapsible container structure is provided, which substantially reduces the problems which have hitherto been unresolved according to the prior art.
Det laminerade substratet och det laminerade skulder- stycket 20 eliminerar fullständigt produktgenomträng- ning och syreabsorption, och detta ytterst önskvärda resultat uppnås genom användning av billiga material, som företrädesvis kombineras till laminerad form på det sätt som antytts i fig 2.The laminated substrate and the laminated shoulder piece 20 completely eliminate product penetration and oxygen absorption, and this highly desirable result is achieved by the use of inexpensive materials, which are preferably combined into laminated form in the manner indicated in Fig. 2.
Det yttre skiktet av en polyetylentereftalat är en termoplast som kan sammansmältas under ett sido- sömnadssteg och säkerställer tillräckligt skydd för de mellanliggande pappers- och metallfolieskikten.The outer layer of a polyethylene terephthalate is a thermoplastic that can be fused during a side seaming step and ensures adequate protection for the intermediate paper and metal foil layers.
Sättet att sy ihop en hopfällbar tandkrämstub av den allmänna typ som beskrives här framgår av US patent nr 3 295 725, vilken skall anses utgöra en del av före- liggande beskrivning. 463 868 .Emellertid kan det yttre skiktet av polyalkylentereftalat och papper elimineras, om foliebarriären är tillräckligt tjock för att motstå skador, och härvid införes flytande termoplastiskt material i den överlappande sidosömmen under dess försegling, när ett sådant system utnyttjas.The method of sewing together a collapsible toothpaste tube of the general type described herein is disclosed in U.S. Patent No. 3,295,725, which is to be construed as part of the present specification. 463 868. However, the outer layer of polyalkylene terephthalate and paper can be eliminated if the film barrier is thick enough to withstand damage, thereby introducing liquid thermoplastic material into the overlapping side seam during its sealing, when such a system is used.
Vidare kan det yttre skiktet vara papper i ett tre- skiktslaminat med papper, folie och en polyalkylen- tereftalat såsom beskrivits. Då de yttersta och innersta skikten företrädesvis är samma kan de vikta kanterna på tuben som framställes av substratet enkelt värme- förseglas. Ett lämpligt bindemedel kan användas när värmeförsegling inte är möjlig. Denna modifikation är förutom de tidigare nämnda fyrskiktslaminaten samman- satta av utifrån och in polyalkylentereftalat, papper, folie och polyalkylentereftalat; eller polyalkylenter- eftalat, folie, papper och polyetylentereftalat. Givet- vis kan lämpliga bindemedel utnyttjas mellan laminat- skikten så snart detta är nödvändigt. Liknande upp- byggnad kan utnyttjas för skulderstycket, kapsylen, halsen, stången, kolven och vid konstruktionen av utmatningsventilér för sådana behållare, särskilt i samband med att de inre delarna utsättes för det inne- slutna tandvårdsmedlet och återigen när så erfordras kan givetvis lämpliga bindemedel utnyttjas.Furthermore, the outer layer may be paper in a three-layer laminate with paper, foil and a polyalkylene terephthalate as described. Since the outermost and innermost layers are preferably the same, the folded edges of the tube made of the substrate can be easily heat sealed. A suitable adhesive can be used when heat sealing is not possible. This modification is in addition to the previously mentioned four-layer laminates composed of external and internal polyalkylene terephthalate, paper, foil and polyalkylene terephthalate; or polyalkylene terephthalate, foil, paper and polyethylene terephthalate. Of course, suitable adhesives can be used between the laminate layers as soon as this is necessary. Similar construction can be used for the shoulder piece, the cap, the neck, the rod, the piston and in the construction of discharge valves for such containers, especially in connection with the inner parts being exposed to the enclosed dentifrice and again when necessary suitable binders can of course be used. .
Olika modifikationer av uppfinningen har beskrivits häri och dessa och andra förändringar kan givetvis utföras utan att härigenom hamna utanför ramen för föreliggande uppfinning. Vidare kommer materialet, när det gjutes som en film på innerytorna hos fiber- trummor som utnyttjas för lagring av smaksatt tand- vårdsmedel att minska hastigheten för aromförlust till trummorna, och därigenom förlänga lagringslivs- längden. 463 868 Polyetylentereftalatet (PET) är särskilt användbart eftersom det har mycket låg aromabsorptionskarakteristika, vilket framgår av nedanstående tabeller, där PET jäm- föres med polyetylen, varvid tjocklekarna för skikten eller beläggningen är desamma: Tabell 1 Aromabsorntion från en tandvårdsmedelpasta (Åldringsbetingelse: 1 vecka vid rumstemperatur) Arom absorberad (%) PET 0,1 aluminiserad PET (1,5 - 2 ohm) 0,0 aluminiserad PET (2 - 3 ohm) nylon 6,6 polyetylen 2,4 Tabell II Aromabsorption från en tandvårdsmedelgel (Åldringsbetingelse: 2 veckor vid rumstemperatur) Arom absorberad (%) PET 0,0 aluminiserad PET (1,5 - 2 ohm) 0,0 aluminiserad PET (2 - 3 ohm) 0,0 nylon 6,6 0,2 1,0 polyetylenVarious modifications of the invention have been described herein and these and other changes may, of course, be made without departing from the scope of the present invention. Furthermore, when cast as a film on the inner surfaces of fibrous drums used for storing flavored dentifrice, the material will reduce the rate of aroma loss to the drums, thereby extending the shelf life. 463 868 The polyethylene terephthalate (PET) is particularly useful because it has very low aroma absorption characteristics, as shown in the following tables, where PET is compared with polyethylene, the thicknesses of the layers or coating being the same: Table 1 Aroma absorption from a dentifrice paste (Aging condition: 1 at room temperature) Aroma absorbed (%) PET 0.1 aluminized PET (1.5 - 2 ohms) 0.0 aluminized PET (2 - 3 ohms) nylon 6.6 polyethylene 2.4 Table II Aroma absorption from a dentifrice gel (Aging condition: 2 weeks at room temperature) Aroma absorbed (%) PET 0.0 aluminized PET (1.5 - 2 ohms) 0.0 aluminized PET (2 - 3 ohms) 0.0 nylon 6.6 0.2 1.0 polyethylene
