Description
Die vorliegende Erfindung betrifft Behälter und insbesondere zusammendrückbare Spender, deren Behälterteil aus laminierten Wänden gebildet ist, wobei in allen dafür anfälligen Bereichen des Behälters Produktpermeation und -absorption sowie Sauerstoffabsorption im wesentlichen unterdrückt werden.The present invention relates to containers and, more particularly, to collapsible dispensers, the container portion of which is composed of Laminated walls is formed, with product permeation in all areas of the container that are prone to this and absorption as well as oxygen absorption are substantially suppressed.
Im Verpackungsbereich sind aus Metall oder Kunststoff bestehende zusammendrückbar Tuben seit langem bekannt. Tuben aus extrudiertem Metall sind brüchig und längererIn the packaging sector, compressible tubes made of metal or plastic have long been known. Extruded metal tubes are brittle and longer

Ware aus einer anderen Stelle als der im wesentlichen starren Spenderöffnung austritt. Von den bekannten Metalltuben sind Aluminiumtuben, die wahrscheinlich am wenigsten brüchig sind, in ihrem Anwendungsbereich eingeschränkt, daGoods emerge from a point other than the essentially rigid dispenser opening. From the well-known metal tubes Aluminum tubes, which are likely to be the least fragile, are limited in their scope because of this

verhindern. Abgesehen von der relativ brüchigen Natur 25impede. Apart from the relatively fragile nature 25
einer Metalltube kommt hinzu, daß die genannte innere Beschichtung eine zusätzliche Herstellungsstufe erfordert, die notwendigerweise den Preis des fertigen Artikels erhöht.a metal tube is added to that said inner tube Coating requires an additional manufacturing stage, which necessarily increases the price of the finished item elevated.
Tuben aus Polyethylen und anderen Kunststoffen werden zur Verpackung vieler Materialien verwendet. Es wurde jedoch beobachtet, daß bestimmte Waren nach einiger Zeit in solchen Behältern verderben. Kunststoff wie beispielsweiseTubes made from polyethylene and other plastics are used to package many materials. It did, however observed that certain goods spoil after a while in such containers. Plastic such as
Polyethylen ist in gewissem Ausmaß permeabel, wenn er in 35Polyethylene is permeable to some extent when put in 35
den für tubenförmige Behälter verwendeten Wandstärken eingesetzt wird. Die in den meisten Zahnpasten zur Geschmacksverleihung enthaltenen essentiellen Öle nehmen volumenmäßig während der Lagerung des Behälters ab, wodurch die Zahnpasta weniger schmackhaft wird. Weiterhin absorbiert die Wand des Plastikbehälters mit der Zeit Sauerstoff und schließlich wird das Produkt zersetzt, was bei fluoridhaltigen Zahnpasten in der Tat beobachtet wurde.the wall thicknesses used for tubular containers is used. Take the essential oils found in most toothpastes for flavoring in volume during storage of the container, making the toothpaste less tasty. Farther the wall of the plastic container will absorb oxygen over time and eventually the product will decompose, which has indeed been observed with toothpastes containing fluoride.
Dementsprechend wurde vorgeschlagen, eine Sperrschicht aus einer relativ dünnen Metallfolie zwischen der Ware und dem Tubenkörper aus Polyethylen anzuordnen, um den genannten Verlust an essentiellen Ölen und die Absorption von Sauerstoff zu verhindern. Gemäß einem Vorschlag bildet die Metallsperrschicht eine Zwischenschicht zwischen Lagen aus Polyethylen; durch Erhitzen mit oder ohne geeigneten Klebstoffen wird ein Laminat hergestellt. Obwohl eine Struktur dieses allgemeinen Typs einen Teil der Produktpermeation und der Sauerstoffabsorption durch den Tubenkörper verhindert, insbesondere dann, wenn die innere thermoplastische Schicht ein Copolymer aus einem Olefin und einem eine polare Gruppe enthaltenden Monomer ist, das mit diesem copolymerisierbar ist, bleibt dennoch die Möglichkeit, daß die Ware verdirbt, wenn auch in viel geringerem Ausmaß.Accordingly, it has been proposed to place a barrier layer of a relatively thin metal foil between the goods and to arrange the tube body made of polyethylene, in order to avoid the mentioned loss of essential oils and the absorption to prevent oxygen. According to one proposal, the metal barrier layer forms an intermediate layer between layers of polyethylene; a laminate is made by heating with or without suitable adhesives. Although a structure of this general type does some of the product permeation and oxygen absorption through Prevents the tube body, especially if the inner thermoplastic layer is a copolymer of a Olefin and a polar group-containing monomer copolymerizable therewith still remains the possibility of the goods spoiling, albeit to a much lesser extent.
Ein Nachteil der Polyolefinoberflache liegt in der mangelnden Eignung der Oberfläche für die Annahme von Druck- und Dekorationsmaterialien. Außerdem zeigt das Polyolefin einen Gedächtniseffekt; d.h., es bleibt nach dem Drücken nicht zusammengedrückt, was bei Zahnpastatuben ein besonderer Nachteil ist. Um diesen Mangel an Zusammendrückbarkeit zu beheben, muß die Metallschicht relativ dick sein, so daß ihre Zusammendrückbarkeit auf den Kunststoff übertragen wird.A disadvantage of the polyolefin surface is the lack of it Suitability of the surface for the acceptance of printing and decoration materials. In addition, the polyolefin shows a memory effect; i.e., it does not remain compressed after pressing, which is a special thing with toothpaste tubes Disadvantage is. To remedy this lack of compressibility, the metal layer must be relatively thick so that their compressibility is transferred to the plastic.

Aufgabe der Erfindung ist es daher, zur Überwindung der genannten Nachteile einen zusammendrückbaren Spender
vorzuschlagen, der in seinem Behälterbereich laminierte Wände aufweist.
5The object of the invention is therefore to propose a compressible dispenser, which has laminated walls in its container area, in order to overcome the disadvantages mentioned.

Zur Lösung dieser Aufgabe wird ein tubenförmiger Behälter vorgeschlagen, dessen Körper mehrere miteinander verbundene Schichten aufweist, wobei eine dieser Schichten, etwa eine Metallfolie, eine Sperrschicht gegen Produktdurchtritt und Sauerstoffabsorption bildet und eine weitere Schicht aus einem Polyalkylenmaterial wie Polyethylenterephthalat oder Polybutylenterephthalat oder einem Copolymer mit einer geringen Menge an einer anderen Dicarbonsäure besteht, wobei Dichte, Schmelzpunkt und Kristallinität variabel sind. Die letztere Schicht bildet die Innenschicht und vorzugsweise die Außenschicht, wobei zwischen diesen verschiedene weitere Laminatschichten angeordnet sind.A tube-shaped container is used to solve this problem proposed whose body has several interconnected layers, one of these layers, for example a metal foil that forms a barrier layer against product penetration and oxygen absorption and another Layer of a polyalkylene material such as polyethylene terephthalate or polybutylene terephthalate or a Copolymer with a small amount of another dicarboxylic acid, with density, melting point and Crystallinity are variable. The latter layer forms the inner layer and preferably the outer layer, wherein between these various further laminate layers are arranged.

Durch den erfindungsgemäßen zu s aminen drückbar en Behälter werden die genannten Nachteile aus dem Stand der Technik überwunden. Der laminierte Behälterkörper und das laminierte Schulterstück 2 0 verhindern völlig die Produktpermeation und die Sauerstoffabsorption; dieses äußerst erstrebenswerte Resultat wird unter Verwendung preisgünstiger Materialien erzielt, die vorzugsweise auf die in FigurBy means of the container according to the invention which can be pressed to form amines the disadvantages mentioned from the prior art are overcome. The laminated container body and the laminated one Shoulder piece 2 0 completely prevent product permeation and oxygen absorption; this extremely desirable The result is achieved using inexpensive materials, which are preferably based on those shown in FIG
2 gezeigte Weise zu einem Laminat vereinigt werden.2 can be combined to form a laminate.
Die Außenschicht aus einem Polyethylenterephthalat bes.teht aus einem thermoplastischen Material, das bei der Seitennahtbildungsstufe schweißbar ist und daß der Papier- und der Metallfolienzwischenschicht angemessenen Schutz bietet. Die Nahtbildung bei einer zusammendrückbaren Zahnpastatube des hier offenbarten allgemeinen Typs ist in der US-PS 3 295 725 beschrieben.The outer layer made of a polyethylene terephthalate bes.teht consists of a thermoplastic material that is used in the side seam formation stage is weldable and that the paper and metal foil interlayers have adequate protection offers. Seam formation in a compressible tube of toothpaste of the general type disclosed herein is shown in FIG U.S. Patent 3,295,725.

Verschiede Modifikationen der Erfindung wurden offenbart, die neben anderen zum erfindungsgemäßen Konzept gehören. Wenn das erfindungsgemäße Material als Folie auf die Innenflächen der Trommeln aus Fasermaterial aufgebracht wird, die zur Lagerung der aromatisierten Zahnpasten verwendet werden, dann verlangsamt das erfindungsgemäße Material den Verlust an Geschmacksstoffen in den Trommeln und erhöht dadurch die Lagerfähigkeit.Various modifications of the invention have been disclosed which, among others, belong to the inventive concept. If the material according to the invention as a film on the Inner surfaces of the drums made of fiber material are applied, which are used to store the flavored toothpastes are used, the inventive material slows down the loss of flavor in the drums and thereby increases the shelf life.
Das Polyethylenterephthalat (PET) ist besonders geeignet, da es eine sehr niedrige Geschmackstoffabsorption zeigt, wie aus den folgenden Tabellen ersichtlich ist, in denen PET mit Polyethylen verglichen wird, wobei die Dicken der Schichten oder Überzüge gleich sind:The polyethylene terephthalate (PET) is particularly suitable because it shows a very low flavor absorption, as can be seen from the following tables, in which PET is compared to polyethylene, the thicknesses the layers or coatings are the same:
