Description
Die Erfindung betrifft eine autoklavierbare Tube für Nahrungsmittel für Tiere oder Menschen, insbesondere für pastöse Tiernahrung.The invention relates to an autoclavable tube for food for animals or humans, in particular for pasty pet food.
Es ist bekannt, beispielsweise Snacks für Hunde oder Katzen in Tubenform zur Verfügung zu stellen. Weiter ist es bekannt, diese Nahrungsmittel zur Haltbarmachung in einem Autoklaven thermisch zu behandeln. Zu diesem Zwecke werden die Tuben mitsamt Inhalt in den Autoklaven verbracht und dort der thermischen Behandlung unterzogen. Hierfür geeignete Tuben bestehen im Stand der Technik im Wesentlichen aus Aluminium.It is known, for example, to provide snacks for dogs or cats in tube form. It is also known to thermally treat these foods for preservation in an autoclave. For this purpose, the tubes are placed together with the contents in the autoclave and subjected there to the thermal treatment. Tubes suitable for this purpose consist essentially of aluminum in the prior art.
Es ist Aufgabe der vorliegenden Erfindung, eine Alternative zu dem im Stand der Technik bekannten, autoklavierbaren Aluminiumtuben zur Verfügung zu stellen.It is an object of the present invention to provide an alternative to the known in the art, autoclavable aluminum tubes available.
Diese Aufgabe wird gelöst durch eine (Kunststoff-)Tube mit den Merkmalen des Anspruchs 1 und eine (Kunststoff-)Tube mit den Merkmalen des Anspruchs 10.This object is achieved by a (plastic) tube having the features of
Eine erfindungsgemäße autoklavierbare (Kunststoff-)Tube für Nahrungsmittel für Tiere oder Menschen, insbesondere für pastöse Tiernahrung, umfasst einen Tubenkörper, der aus einem Material besteht, das über eine Polypropylen aufweisende Schicht verfügt, insbesondere über eine aus Polypropylen bestehende Materialschicht, sowie über eine Sauerstoffbarriere.An autoclavable (plastic) tube for food for animals or humans, in particular for pasty pet food according to the invention, comprises a tube body which consists of a material which has a polypropylene-containing layer, in particular via a material layer consisting of polypropylene, and via an oxygen barrier ,
Es hat sich gezeigt, dass Polypropylen ein für die erfindungsgemäße Tube geeigneter Kunststoff ist. Insbesondere hält es die für einen Autoklaviervorgang notwendigen Temperaturen aus (in der Regel oberhalb von 100°C), ohne Schaden zu nehmen.It has been found that polypropylene is a suitable for the tube according to the invention plastic. In particular, it keeps the temperatures necessary for an autoclaving process (usually above 100 ° C) without being damaged.
Die Sauerstoffbarriere der Tube sorgt dafür, dass die Haltbarkeit des Nahrungsmittels negativ beeinflussender Sauerstoff nicht oder nur in vernachlässigbarer Menge durch den Tubenkörper in das Tubeninnere bzw. in den von dem Tubenkörper eingeschlossenen Innenraum dringen kann.The oxygen barrier of the tube ensures that the life of the food negatively influencing oxygen can not penetrate or only in negligible amount through the tube body into the tube interior or in the enclosed by the tube body interior.
Erfindungsgemäß wird daher erstmals eine zu den gängigen Aluminiumtuben alternative, autoklavierbare (Kunststoff-)Tube zur Verfügung gestellt.Therefore, according to the invention, an alternative to the common aluminum tubes, autoclavable (plastic) tube is provided for the first time.
Der Begriff ”autoklavierbar” bezieht sich im Rahmen dieser Anmeldung allgemein auf die Fähigkeit der Tube bzw. des verwendeten Materials, den üblicherweise im Rahmen des Autoklavierens vorherrschenden Prozessparametern, wie Temperatur und Druck, standhalten zu können bzw. den Prozess (vollständig oder im Wesentlichen) unbeschadet überstehen zu können.For the purposes of this application, the term "autoclavable" generally refers to the ability of the tube or of the material used to be able to withstand the process parameters usually prevailing during autoclaving, such as temperature and pressure, or the process (complete or substantial). unscathed to survive.
Was die oben erwähnte Sauerstoffbarriere betrifft, so kann diese beispielsweise eine Schicht aus EVOH sein, aus Aluminium, eine Schicht aus metallisiertem PET oder eine Schicht aus einem autoklavierbaren Kunststoffmaterial mit SiOx.As for the above-mentioned oxygen barrier, it may be, for example, a layer of EVOH, aluminum, a layer of metallized PET or a layer of an autoclavable plastic material containing SiO x .
Es ist aber auch denkbar, dass die Sauerstoffbarriere keine separate Schicht des für den Tubenkörper verwendeten Materials bildet, sondern in die Polypropylenschicht bzw. in die Polypropylenmatrix integriert ist, beispielsweise durch geeignete Zusätze zu dem Polypropylenmaterial.However, it is also conceivable that the oxygen barrier does not form a separate layer of the material used for the tube body, but is integrated in the polypropylene layer or in the polypropylene matrix, for example by suitable additives to the polypropylene material.
Allgemein gesprochen besteht der Tubenkörper bzw. die Wandung desselben bevorzugt aus einem Verbundmaterial aus mehreren Schichten bzw. einem Mehrschichtmaterial, insbesondere einem Laminat, wobei jeweils benachbarte Schichten flächig aneinander anliegen. Jeweils aneinander angrenzende Schichten sind dabei miteinander verbunden.Generally speaking, the tube body or the wall thereof preferably consists of a composite material of a plurality of layers or of a multi-layer material, in particular a laminate, wherein adjacent layers abut each other flatly. Each adjacent layers are connected to each other.
Ein solches Mehrschichtmaterial ist bzw. wird erfindungsgemäß vorzugsweise im Cast-Film-Verfahren hergestellt.Such a multilayer material is or is preferably produced according to the invention in the cast-film process.
Gemäß einer besonders bevorzugten Ausführungsform der vorliegenden Erfindung besteht eine weiter innenliegende Materialschicht eines entsprechenden Mehrschichtmaterial des Tubenkörpers aus Polypropylen und eine weiter außen liegende weitere Materialschicht aus einem – ebenfalls für den Einsatz in einem Autoklaven geeigneten – Kunststoffmaterial, bevorzugt ebenfalls Polypropylen, wobei zwischen diesen eine Sauerstoffbarriereschicht angeordnet ist, beispielsweise aus einem der oben genannten Sauerstoffbarrierematerialien.According to a particularly preferred embodiment of the present invention, a further inner layer of material of a corresponding multilayer material of the tube body of polypropylene and a further outer layer further material of a - also suitable for use in an autoclave - plastic material, preferably also polypropylene, with an oxygen barrier layer between them is arranged, for example, from one of the above-mentioned oxygen barrier materials.
Grundsätzlich kann das Mehrschichtmaterial bei diesem Aufbau noch weitere Schichten aufweisen.In principle, the multilayer material may have further layers in this construction.
Es ist aber auch denkbar, dass das Mehrschichtmaterial desselben letztlich nur aus diesen vorgenannten drei Schichten besteht, nämlich der inneren Schicht aus Polypropylen, der äußeren, gegebenenfalls außenseitig zudem bedruckten und oberflächenveredelten Schicht aus Polypropylen und der zwischen diesen Polypropylenschichten angeordneten Sauerstoffbarriereschicht.However, it is also conceivable that the multilayer material of the latter ultimately consists only of these aforementioned three layers, namely the inner layer of polypropylene, the outer, optionally also printed on the outside and surface-finished layer of polypropylene and arranged between these polypropylene layers oxygen barrier layer.
Die Begriffe ”innen” und ”außen” bzw. ”weiter innen” und ”weiter außen” beziehen sich dabei auf die Anordnung der Schichten des Mehrschichtmaterials in Bezug auf die Lage relativ zu bzw. die Entfernung zu dem Innenraum des von dem Mehrschichtmaterials gebildeten Tubenkörpers, in dessen Innenraum das Nahrungsmittel als Tubeninhalt angeordnet ist/wird.The terms "inside" and "outside" or "further inside" and "further outside" refer to the arrangement of the layers of the multilayer material with respect to the position relative to or the distance to the interior of the tube body formed by the multilayer material in whose interior the food is / is arranged as tube contents.
Was die Tubenschulter der erfindungsgemäßen Tube betrifft, so ist sie vorzugsweise ebenfalls aus einem Material hergestellt, das mindestens eine Schicht aus Polypropylen umfasst.As regards the tube shoulder of the tube according to the invention, it is preferably also made of a material comprising at least one layer of polypropylene.
Ebenfalls bevorzugt weist auch die Tubenschulter der Tube eine entsprechende Sauerstoffbarriere auf, insbesondere eine Sauerstoffbarriereschicht.Also preferably, the tube shoulder of the tube has a corresponding oxygen barrier, in particular an oxygen barrier layer.
Die Sauerstoffbarriere bzw. die Sauerstoffbarriereschicht kann dabei so wie oben für den Tubenkörper beschrieben ausgebildet sein. Insbesondere kann sie aus einem der oben für den Tubenkörper beschriebenen Materialien oder Materialschichten ausgebildet sein.The oxygen barrier or the oxygen barrier layer can be designed as described above for the tube body. In particular, it may be formed from one of the materials or material layers described above for the tube body.
Vorzugsweise ist die Tubenschulter ebenfalls aus einem Mehrschichtmaterial (aus Kunststoff) ausgebildet, insbesondere einem Laminat, das mindestens eine Schicht aus Polypropylen umfasst sowie eine Sauerstoffbarriereschicht.Preferably, the tube shoulder is also formed of a multi-layer material (made of plastic), in particular a laminate comprising at least one layer of polypropylene and an oxygen barrier layer.
Eine in der oben beschriebenen Weise spezifizierte, autoklavierbare Tube kann erfindungsgemäß dazu verwendet werden, darin enthaltene Nahrung für Tiere oder Menschen zu autoklavieren. Die gesamte Tube wird dann mitsamt der in dieser bzw. in dem Innenraum des Tubenkörpers enthaltenen Nahrung in einen Autoklaven verbracht und dort entsprechend thermisch behandelt.An autoclavable tube specified in the manner described above can be used according to the invention to autoclave food for animals or humans contained therein. The entire tube is then brought together with the food contained in this or in the interior of the tube body in an autoclave and treated there accordingly.
