Description

Leicht zu öffnender Verpackungsbehälter Seit einigen Jahren werden verderbliche Lebensmittel in flachen sterilisierbaren Schälchen verpackt.Easy-to-open packaging container has been used for several years Perishable food packaged in flat, sterilizable bowls.

Das eigentliche Schälchen besteht z.B. aus einem Aluminiumband der Dicke o,lo mm. Die Außenseite ist mit einer farblosen oder gefarbten Lackschicht von ca. o,oo5 mm Dicke versehen, während die Innenseite mit einer ungereckten Polypropylenfolie von 0,050 mm Dicke kaschiert ist, Das Schälchen wird aus dieser Verbundfolie durch einen dem Tiefziehen ähnlichen Umform-Prozeß hergestellt. Nach dem Ftillen des Schälohens mit dem zu verpackenden FUllgut wird ein Deckel aus einem gleichartig aufgebauten Verbundmaterial mitteils Druck und Hitze auf den flachen Schälohenrand aufgesiegelt. Anschließend wird die fertige Verpackung gegebenenfalls noch sterilisiert.The actual bowl consists e.g. of an aluminum band of Thickness 0.1 mm. The outside is covered with a colorless or colored layer of varnish approx. 0.05 mm thick, while the inside is covered with an unstretched polypropylene film 0.050 mm thick is laminated, the bowl is made of this composite film through produced a forming process similar to deep drawing. After filling the Schälohens With the contents to be packaged, a lid is made from a similarly constructed one The composite material is sealed onto the flat edge of the peel using pressure and heat. The finished packaging is then optionally sterilized.

Das öffnen solcher Schälchen, zwecks Entnahme des Inhalts, geschieht üblicherweise durch Aufschneiden entlang der Siegelnaht mit Hilfe eines spitzen Messers. Weil diese Art der ordnung nicht befriedigt, ist schon eine andere Offnungsmöglichkeit vorgeschlagen. Hierzu wird das Aluminium band ftlr den Deckel statt mit einer ungereckten mit einer dünnen biaxial gereckten Polypropylenfolie kaschiert. Wird der Deckel aus diesem Verbundrnaterlal auf den SahWlchenrantl gesiegelt, dann schrumpft die gereckte Polypropylenfolie in der Nähe der Siegelnaht unter gleichzeitiger Einbuße an Festigkeit. Der Deckel wird dann zweckmäßig noch mit einer Uber den Deckelrand hinausragenden Aufreißlasche versehen und es gelingt auf diese Weise den Deckel ohne Zuhilfenahme eines Werkzeuges einfach durch Abreißen zu entfernen, wobei die Polypropylenfolie entlang der Siegelnaht zerreißt. Die gewünschte mechanische Schwächung der Polypropylenfolie in der Nähe der Siegelnaht durch den Schrumpfprozeß ist von der Bildung zahlreicher Poren in der Propylenfolie begleitet und die darunter liegende Klebstoffschicht bietet nur einen unvollkommenen Schutz des Aluminiumbandes. Wird nun ein chemisch aggressives Füllgut verpackt, wie z.B. stark gewürzte, salzhaltige oder saure Fleisch- oder Fischwaren, dann korrodiert das Aluminium unter den Poren der Kunststoff-Folie. Deshalb ist diese bequeme OfRnungsmethode bisher auf nicht korrodierende Füllgüter beschränkt.Such bowls are opened for the purpose of removing the contents usually by cutting open along the sealing seam with the help of a pointed Knife. Because this type of order is unsatisfactory, there is another possibility of opening suggested. To do this, the aluminum band is attached to the lid instead of an unstretched one laminated with a thin biaxially stretched polypropylene film. Will the lid from this composite material to the SahWlchenrantl sealed, then the stretched polypropylene film shrinks in the vicinity of the sealing seam while at the same time Loss of strength. The lid is then expediently still with an over the edge of the lid protruding pull tab provided and it succeeds in this way the lid can be removed simply by tearing off without the aid of a tool, whereby the Polypropylene film tears along the sealing seam. The desired mechanical weakening of the polypropylene film near the sealing seam due to the shrinking process is from accompanied the formation of numerous pores in the propylene film and the one below The adhesive layer only provides imperfect protection for the aluminum tape. Will a chemically aggressive product is now packaged, such as strongly spiced, salty or acidic meat or fish products, then the aluminum corrodes under the pores the plastic film. This is why this convenient opening method has not yet been opened limited corrosive products.

Erfindungsgemäß wird dieser Nachteil dadurch behoben, daß das Aluminiumband des Deckels auf der Innenseite unter der Klebstoffschicht und der heißsiegelfähigen biaxial gereckten Kunststoff-Folie eine Korrosionsschutsohicht trägt. Gegen-.According to the invention, this disadvantage is eliminated in that the aluminum strip of the lid on the inside under the adhesive layer and the heat sealable biaxially stretched plastic film has a corrosion protection layer. Against-.

stand der Erfindung ist demzufolge ein leicht zu öffnender Verpackungsbehälter für aggressive FUllgUter aus mit-thermoplastischer Kunststoff-Folie kaschiertem Aluminiumband, der mit einer aufreißbaren Heißsiegelnaht zwischen der Folie des Unterteils und der biaxial gereckten Folie des Deckels versehen ist, gekennzeichnet durch eine Korrosionsschutzschicht unter der biaxial gereckten thermoplastischen Kunststoff-Folie.The present invention is therefore an easy-to-open packaging container for aggressive filling goods made of laminated with thermoplastic plastic film Aluminum tape with a tearable heat-sealed seam between the foil of the The lower part and the biaxially stretched film of the lid is marked by a corrosion protection layer under the biaxially stretched thermoplastic Plastic film.

Diese biaxial gereckten thermoplastischen Kunsttoff-Folien bestehen entweder aus Polyäthylen hoher Dichte oder aus Polypropylen, wobei letzteres bevorzugt wird. Für die Korrosionsschutzschicht eignen sich Einbrennlaoke zum Beispiel auf der Basis von Phenol-Epoxydharzen, 2-Komponenten-Reaktionslacken, insbesondere auf Urethanbasis, zum Beispiel Desmophen-Desmoduroder aus einem rein physikalisch trocknendem Lack? zum Beispiel auf Basis von Nitrozellulose, Ferner besteht die Möglichkeit, anstelle des Lackes als Korrosionsschutzschicht eine Kunststoff-Folie mit hoher Erweichungstemperatur, z.B. aus Polyäthylenterephthalat, zwischen dem Aluminium und der biaxial gereckten heißsiegelfähigen Kunststoff-Folie aufzubringen.These biaxially stretched thermoplastic plastic films are made either high density polyethylene or polypropylene, the latter being preferred will. For the corrosion protection layer, for example, baked-in laokes are suitable on based on phenolic epoxy resins, 2-component reactive lacquers, in particular on Urethane base, for example Desmophen-Desmodur or from a purely physically drying one Paint? for example based on nitrocellulose, there is also the possibility of Instead of the paint as a corrosion protection layer, a plastic film with a high Softening temperature, e.g. from polyethylene terephthalate, between the aluminum and to apply the biaxially stretched heat-sealable plastic film.

Der Rand des Schälcheist zweckmäßigerweise zur Erhöhung der Festigkeit als Rollrand 4 ausgebildet. Der Deckel 2 ist mit einer Aufreißlasche 3 versehen. Sein Aufbau von außen nach innen ist in der Fig. 2 dargestellt.The bowl 1 consists of an aluminum strip 0.1 mm thick, which is provided on the outside with a layer of varnish 0.05 mm thick and Laminated on the inside with an unstretched polypropylene film 0.05 mm thick is. The edge of the peel is useful to increase the strength than Rolled edge 4 formed. The cover 2 is provided with a pull tab 3. being The structure from the outside to the inside is shown in FIG.

Hierin sind: A) Ein Schutzlack, der das Aluminium gegen Verfärbung beim Sterilisieren durch das Wasser im Autoklaven schützt.Herein are: A) A protective varnish that protects the aluminum against discoloration during sterilization by the water in the autoclave.

Üblich sind hierfür Nitrozellulose- oder Einbrennlacke, die auch eingefärbt sein können. Die Auftragsstärke beträgt 2 - lo ggqm. Nitrocellulose or stoving enamels are common for this, as are can be colored. The application strength is 2 - lo ggqm.

B) Ein Aluminiumband aus weichem oder hartem Reinaluminium oder Legierungen des Aluminiums, insbesondere mit Mangan oder Magnesium. Die Dicke des Bandes liegt nach DIN 1784, Blatt 2, im Bereich von o,o21 bis o,35o mm und Beträgt vorzugsweise 0,05 bis o,l mm.B) An aluminum strip made of soft or hard pure aluminum or alloys of aluminum, especially with manganese or magnesium. The thickness of the tape lies according to DIN 1784, sheet 2, in the range from 0.021 to 0.350 mm and is preferably 0.05 to 0.1 mm.

C) Korrosionsschutzschicht gemäß der Erfindung, AuStragsstärke 3 bis 30 g/qm, vorzugsweise 5 bis lo g/qm.C) Corrosion protection layer according to the invention, application thickness 3 to 30 g / m², preferably 5 to 10 g / m².

D) Die Klebstoffschicht. Vorzugsweise werden hier 2-Komponenten. Polyurethan-Klebstoffe verwendet, die AuStragsstärke beträgt 3 bis lo g/qm.D) The adhesive layer. Preferably 2 components are used here. Polyurethane adhesives used, the application rate is 3 to lo g / sqm.

E) Eine heißsiegelfähige biaxial gereckte Kunststoff-Folie, z.B. aus Polypropylen oder Polyäthylen hoher Dichte von o,ol bis o,o25 mm, vorzugsweise o,ol5 bis o,o20 mm Dicke.E) A heat-sealable biaxially stretched plastic film, e.g. from Polypropylene or high density polyethylene from 0.01 to 0.025 mm, preferably 0.01 to 5 Up to 0.020 mm thick.

Abgesehen davon, daß die Kunststoff-Folie des Deckels biaxial gereckt ist, besteht sie erfindungsgemäß immer aus dem gleichen Material, das zum Kaschieren des Behälterunterteils verwendet ist. Wenn hier eine Polypropylenfolie gewählt wurde, besteht auch die heißsiegelfähige Innenschicht des Deckels aus einer Polypropylenfolie, die jedoch biaxial gereckt ist, um ein leichtes offenen durch Aufreißen entlang der Siegelnaht zu ermöglichen.Apart from the fact that the plastic film of the lid is biaxially stretched is, according to the invention it always consists of the same material that is used for lamination of the container base is used. If a polypropylene film was chosen here, the heat-sealable inner layer of the lid also consists of a polypropylene film, which, however, is biaxially stretched to a slight open by tearing along to enable the sealing seam.

In der erfindungsgemäßen Weise aufgebaute Verpackungsbehälter haben sich auch fUr chemisch aggressive Füllgüter bestens bewährt. Zum Beispiel wuSbn tiefgezogene Schälchen aus dem obengenannten Verbundmaterial (lackiertes Aluminiumband o,ll mm, kaschiert mit ungerecktem Polypropylen o>o5o mm) mit Heringen in Tomatensoße gefüllt. Die Dosen wurden mit einem Deckel versiegelt, der erfindungsgemäß folgenden Aufbau (von außen nach innen) hatte: Melamin-Epoxyd-Lack : 4 g/qm Aluminiumband, weich : mit 98,6 Al : 05 o70 mm Phenol-Epoxyd-Lack : 7 g/qm 2-Komponenten-Polyurethan-Kleber : 5 g/qm Biaxial gereckte Polypropylenfolie : 0,015 mm.Have packaging containers constructed in the manner according to the invention has also proven its worth for chemically aggressive filling goods. For example wuSbn Deep-drawn bowls made from the above-mentioned composite material (lacquered aluminum strip o, ll mm, laminated with unstretched polypropylene (> o5o mm) with herrings in tomato sauce filled. The cans were sealed with a lid according to the invention Structure (from outside to inside) had: Melamine-epoxy paint: 4 g / sqm aluminum tape, soft: with 98.6 Al: 05 o70 mm phenol epoxy paint: 7 g / sqm 2-component polyurethane adhesive : 5 g / qm Biaxially oriented polypropylene film: 0.015 mm.

Die Siegeltemperatur betrug 220°C bei einer Siegelzeit von o,5 sec.The sealing temperature was 220 ° C. with a sealing time of 0.5 seconds.

Anschließend wurden die Schälchen im Autoklaven bei einem Gegendruck von 2,8 atü 4o Minuten bei 1210C sterilisiert.The bowls were then placed in the autoclave at a counter pressure sterilized from 2.8 atmospheres for 40 minutes at 1210C.

Zum Vergleich wurde ein Teil der Schälchen mit Deckeln versehen, die sich lediglich durch Fortfall des als Korrosionsschutzschicht dienenden Phenol-Epoxyd-Lackes von den erfindungsgemäßen Dedc eln -unterschieden.For comparison, some of the bowls were provided with lids that only by eliminating the phenol-epoxy paint used as a corrosion protection layer differ from the dedc eln according to the invention.

Nach sechsmonatiger Lagerzeit der sterilisierten Dosen bei normaler Raumtemperatur zeigten die Dosen mit den erfindungsgemäßen Deckeln keinerlei Korrosionsschäden, während die Deckel ohne Korrosionsschutzschicht starke Korrosionen aufwiesen.After six months of storage of the sterilized cans at normal The cans with the lids according to the invention showed no corrosion damage whatsoever at room temperature, while the lids without an anti-corrosion layer showed severe corrosion.
