Description

Die Erfindung betrifft Behälter enthaltend den PMMA-Pulveranteil eines Zweikomponentensystems aus PMMA-Pulverkomponente und MMA-Monomerkomponente sowie Verwendungen derartiger Behälter. Das Zweikomponentensystem ist beispielsweise ein Dentalmaterial.The invention relates to containers comprising the PMMA powder portion of a two-component system of PMMA powder component and MMA monomer component and uses of such containers. The two-component system is for example a dental material.

Hintergrund und AufgabenstellungBackground and task

Bei der Herstellung von herausnehmbarem Zahnersatz wie Voll- oder Teil-Zahnprothesen wird sogenanntes Prothesenbasismaterial verwendet. Durch Vermischen eines Pulvers überwiegend basierend auf PMMA und einer Flüssigkeit, die hauptsächlich aus MMA besteht, entsteht nach Aushärtung ein in der Regel zahnfleischfarbenes Polymer, von dem die künstlichen Zähne der Voll- bzw. Teilprothese gehalten werden. Trotz genauer Vorgaben der Hersteller in der Gebrauchsanleitung über das Mischungsverhältnis von Pulver und Flüssigkeit dosiert die Mehrzahl der Anwender "nach Gefühl" über die Viskosität der dabei entstehenden Mischung. Hierdurch ergeben sich Schwankungen in den Werkstoffeigenschaften, im Farbeindruck und im Schrumpfungsverhalten. Außerdem ergibt sich durch das nicht-stöchiometrische Mengenverhältnis ein erhöhter Restmonomergehalt und damit einhergehend eine höhere gesundheitliche Belastung der Patienten. Zudem treten durch den erwähnten variablen Schrumpf Passungenauigkeiten der zahntechnischen Arbeit auf.In the production of removable dentures such as full or partial dentures so-called denture base material is used. By mixing a powder predominantly based on PMMA and a liquid, which consists mainly of MMA, is formed after curing a gum-colored polymer, of which the artificial teeth of the full or partial denture are held. Despite precise specifications of the manufacturers in the instructions for use on the mixing ratio of powder and liquid, the majority of users dosed "by feel" about the viscosity of the resulting mixture. This results in fluctuations in the material properties, in the color impression and in the shrinkage behavior. In addition, the non-stoichiometric ratio results in an increased residual monomer content and, consequently, a higher health burden on the patients. In addition, due to the mentioned variable shrink fit inaccuracies of the dental work on.

Lösliche Behälter zur Aufbewahrung von Pulver oder kompaktierten Feststoffen sind an sich bekannt. EP 0 642 985 B1 offenbart ein Verpackungssystem für gefährliche Zusammensetzungen mit einem äußeren und einem inneren, jeweils wasserlöslichen oder -dispergierbaren Beutel. Sie dienen der getrennten Aufbewahrung zweier gefährlicher landwirtschaftlicher Mittel, wobei der äußere Beutel zusätzlich zum Mittel einen oder mehrere mit dem anderen Mittel gefüllte innere Beutel enthält. Gemäß Anspruch 17 werden bestimmte Dosiermengen eingehalten. Die gesamte Verpackung ist zur Auflösung in Wasser vorgesehen.Soluble containers for storing powder or compacted solids are known per se. EP 0 642 985 B1 discloses a packaging system for hazardous compositions having an outer and an inner, each water-soluble or -dispersible bag. They serve the separate storage of two dangerous agricultural means, wherein the outer bag contains in addition to the means one or more filled with the other agent inner bag. According to claim 17 certain dosage levels are met. The entire packaging is intended for dissolution in water.

Auf dem Gebiet der Wasch- und Geschirrspülmittel haben sich ebenfalls wasserlösliche Verpackungsbeutel etabliert. EP 0 132 726 B1 beschreibt eine Innenverpackung, die bei einer vorgegebenen Temperatur wasserlöslich ist, während die Außenverpackung porös und für Wasser und Produkt durchlässig ist. Die Außenverpackung enthält für gewöhnlich Pulver, und in der Innenverpackung kann eine feste, pastenförmige oder flüssige Komponente gelagert sein. Eine Weiterentwicklung dieses Systems stellt DE 195 37 671 A1 vor. Dort ist der Innenbehälter nicht aus flexibler Folie, sondern aus starrem oder elastischem wasserlöslichem Material, z.B. als Kapsel gestaltet.In the field of detergents and dishwashing agents, water-soluble packaging bags have also become established. EP 0 132 726 B1 describes an inner packaging, which at a predetermined temperature is water-soluble, while the outer packaging is porous and permeable to water and product. The outer packaging usually contains powder and a solid, pasty or liquid component may be stored in the inner packaging. An evolution of this system provides DE 195 37 671 A1 in front. There, the inner container is not made of flexible film, but made of rigid or elastic water-soluble material, eg as a capsule.

EP 941 939 A1 beschreibt ein lösliches Produkt in einem löslichen Behälter, beide zur Auflösung in einer vorgegebenen Menge Lösemittel vorgesehen. Gemäß Anspruch 11 kann es sich auch um zwei ineinanderliegende Behälter mit verschiedenen löslichen Produkten handeln. EP 941 939 A1 describes a soluble product in a soluble container, both intended for dissolution in a given amount of solvent. According to claim 11, it may also be two nested containers with different soluble products.

Aufgabe der Erfindung ist es, einen Behälter und Verwendungen solcher Behälter anzugeben, welche oben genannte Nachteile vermeiden und eine einfache, aber trotzdem exakte Dosierung des PMMA-Pulvers ohne aufwendige und teure Zusatzgeräte ermöglichen. Gelöst wird diese Aufgabe durch die im Anspruch 1 einen Behälter betreffende angegebene Merkmalskombination und die in den Ansprüchen 10 und 11 eine Verwendung eines solchen Behälters betreffenden angegebenen Merkmalskombinationen.The object of the invention is to provide a container and uses such containers, which avoid the above-mentioned disadvantages and allow a simple, but nevertheless exact metering of PMMA powder without consuming and expensive accessories. This problem is solved by the specified feature combination relating to claim 1 in claim 1 and the specified feature combinations relating to the use of such a container in claims 10 and 11.

Im Vorliegenden wird ein Verpackungsmaterial empfohlen, das direkt in der flüssigen Monomerkomponente löslich ist.In the present case, a packaging material is recommended which is directly soluble in the liquid monomer component.

Die Erfindung betrifft somit Behälter enthaltend den PMMA-Pulveranteil eines Zweikomponentensystems aus PMMA-Pulverkomponente und MMA-Monomerkomponente, die aus einem in der MMA-Monomer-Lösung löslichen Material, insbesondere PMMA-Folie bestehen.The invention thus relates to containers comprising the PMMA powder portion of a two-component system comprising PMMA powder component and MMA monomer component, which consist of a material which is soluble in the MMA monomer solution, in particular PMMA film.

Die Wandstärke der Folie beträgt zweckmäßig von 10 bis 2000 µm, insbesondere von 20 bis 200 µm.The wall thickness of the film is suitably from 10 to 2000 .mu.m, in particular from 20 to 200 microns.

Es kann vorteilhaft sein, wenn der Behälter in geschlossenem Zustand eng am PMMA-Pulver anliegt. Dies wird z.B. durch Evakuieren erreicht. Die Geometrie des Behälters ist zweckmäßigerweise so gestaltet, dass der Folienanteil möglichst gering ist. Der Behälter kann mikroperforiert sein, wobei die Lochgrößen unterhalb der Partikelgröße des verpackten Pulvers liegen. Der Behälter kann in bekannter Weise ausgestaltet sein, z.B. als Flachbeutel, Flachbeutel mit Euroloch, Flachbeutel mit Rundloch, Kettenbeutel, Standbodenbeutel, Seitenfaltbeutel, Stabilpackbeutel, Drei-Siegelrandbeutel, Vier-Siegelrandbeutel, tetraederförmiger Beutel, Blockbodenbeutel, Kapsel oder Muldenverpackung.It may be advantageous if the container in the closed state is close to the PMMA powder. This is achieved, for example, by evacuation. The geometry of the container is expediently designed so that the film content is as low as possible. The container may be microperforated, with the hole sizes below the particle size of the packaged powder. The container can be configured in a known manner, eg as a flat bag, flat bag with Euro hole, flat bag with round hole, chain bag, stand-up bag, side-folding bag, stabilized bag, three-edge bag, four-edge bag, tetrahedral bag, block bottom bag, capsule or trough packaging.

Hierzu bieten sich Polymerfolien z.B. aus PMMA an.According to the invention, the corresponding amount of powder is packaged in a film soluble in the monomer (e.g., MMA). For this purpose, polymer films are available, for example. from PMMA.

Die Verpackung kann dabei in Form eines Beutels mit einer losen oder verpressten Pulverschüttung oder aber in einer kompakten Füllung mit formschlüssiger Umhüllung durch eine Folie oder einen Film erfolgen.The packaging may be in the form of a bag with a loose or compressed powder bed or in a compact filling with positive wrapping by a film or a film.

Die Folie muss einerseits eine hinreichend hohe Wandstärke aufweisen, um mechanische Belastungen während der Herstellung und des Transportes unbeschadet zu überstehen und dem Produkt einen hinreichenden Schutz gegenüber Umwelteinflüssen, Feuchtigkeit und Schmutz zu bieten, andererseits muss die Folie hinreichend dünn sein, um in möglichst kurzer Zeit an- bzw. aufgelöst zu werden.On the one hand, the film must have a sufficiently high wall thickness in order to withstand mechanical stresses during manufacture and transport, and to provide the product with sufficient protection against environmental influences, moisture and dirt. On the other hand, the film must be sufficiently thin in the shortest possible time to be dissolved or dissolved.

Hier haben sich Materialstärken < 60 µm bewährt.Here, material thicknesses of <60 μm have been proven.
