Abstract

The Parent Patent (3016169) described a method for the mfr., sterilisation and filling of containers, esp. cups for yoghurt, cream and other milk prods., in a continuous flow line. The phase during which the foil is prepd. for the deep drawing operation by preheating is now also carried out with a sterilising medium e.g. steam. The heating surfaces of the preheating station are equipped with shallow recesses and control inlets for the supply of a sterilising hot medium. This heats and sterilises the foil as it moves in steps to the deep drawing station where the cups are produced. This optimises the total effect of the sterilisation and ensures freedom from all germs.

Description

Verfahren und Vorrichtuno zur Herstelluno.Method and device for manufacturing.

Sterilisation und von Behältern -============= = (Zusatz zu P 30 16 169.4) Die Zusatzerfindung betrifft ein Verfahren gemäß Oberbegriff des Hauptanspruches und eine Vorrichtung zu dessen Durchführung.Sterilization and of containers - ============= = (addition to P 30 16 169.4) The additional invention relates to a method according to the preamble of the main claim and a device for its implementation.

Das Verfahren nach der Hauptansmeldung und die zugehörige Vorrichtung zu seiner Durchführung arbeiten, wie sich gezeigt hat, hinsichtlich des Ausformungsvorganges und hinsichtlich des Sterilisationseffektes absolut zufriedenstellend.The method according to the main application and the associated device work for its implementation, as has been shown, with regard to the shaping process and absolutely satisfactory with regard to the sterilization effect.

Es wurde nun gefunden, daß eine weitere Verbesserung erzielt werden kann, die hinsichtlich des Verfahrens darin besteht, daß man unter Ausnutnutzung der Vorwärmphase des Folienbandes auch bereits während dieser das Folienband mit sterilisierendem Medium beaufschlagt.It has now been found that a further improvement can be achieved can, which in terms of the method is that one is taking advantage of the preheating phase of the film tape also during this the film tape with applied to sterilizing medium.

Vorrichtungsmäßig schlägt sich dies nach der vorliegenden Zusatzerfindung einfach darin nieder, daß die Heizflächen der Vorwärmstation mit Ausnehmungen zur mindestens beschickungeseitigen Bespülung des Folienbandes mit sterilisierendem Medium und die Ausnehmungen mit steuerbaren Mediumszuleitungen versehen werden.In terms of device, this is reflected in the present additional invention simply down in the fact that the heating surfaces of the preheating station with recesses for At least on the loading side, the film strip is rinsed with sterilizing agent Medium and the recesses are provided with controllable medium supply lines.

Unabhängig davon wurde ferner gefunden, daß die Aufgabe gemäß Hauptanmeldung P 30 16 169.4 auch noch auf andere Weise gelöst werden kann und zwar im Sinne des Nebenanspruches 3, wobei also mit dem gleichen Sterilisstionseffekt das Tiefziehen in an sich bekannter Weise mittels Matrize und Patrize erfolgt, die Becher aber, im Folienverband verbleibend, mindestens einen Taktschritt weitergerückt und dann während der Ausformung von Folgebehältern mit sterilisierendem Medium beaufschlagt werden.Independently of this, it was also found that the task according to the main application P 30 16 169.4 can also be solved in other ways, namely in the sense of Secondary claim 3, with the deep drawing thus having the same sterilization effect takes place in a manner known per se by means of a female mold and male mold, but the cups, Remaining in the film bandage, advanced at least one step and then acted upon with sterilizing medium during the formation of subsequent containers will.

Vorrichtungsmäßig bedarf dies nur einer Weiterbildung der Vorrichtung im Sinne des Anspruches 4.In terms of device, this only requires a further development of the device within the meaning of claim 4.

Die erfindungegemäBen Zusätze und Nebenlösungen werden nachfolgend anhand der zeichnerischen Darstellung von Ausführungsbeispielen näher erläutert.The additives and secondary solutions according to the invention are described below explained in more detail with reference to the graphic representation of exemplary embodiments.

Es zeigen schematisch Fig. 1 die Vorwärmetation mit anschließender Tiefziehetation und Fig. 2 die Vorrichtung für die Nebenlösung.It shows schematically Fig. 1 the preheating station with subsequent Deep-drawing station and FIG. 2 the device for the secondary solution.

In den Figuren sind die entsprechenden Bezugszeichen benutzt, soweit es sich nicht um neue Teile bzw. Ausbildungen handelt.In the figures, the corresponding reference numerals are used to the extent that they are not new parts or training.

Gemäß Fig. 1 sind die Heizflächen 3' der Vorwärmstation 3 zusätzlich mit flachen Ausnehmungen 30 und mit steuerbaren Mediumszufuhrleitungen 31 versehen, durch die im Arbeits-bzw. Förderschrittakt sterilisierendes Medium in die Ausnehmungen 3c geleitet und damit das Folienband 1 erwärmt und vorsterilisiert-warden kann, was natürlich die Gesamtkeimabtdtung optimiert.According to FIG. 1, the heating surfaces 3 'of the preheating station 3 are additional provided with shallow recesses 30 and with controllable medium supply lines 31, through the work or. Feed step act of sterilizing medium into the recesses 3c and so that the film strip 1 can be heated and pre-sterilized, which of course optimizes the overall germination.

GemäB Fig. 2 ist zur Durchführung der unabhängigen Verfahrenslösung hinter der hier in üblicher Weise ausgebildeten Tiefziehstation 4', die also mkt Patrize 3 und Matrize 34 arbeitet, am Unterteil 8 ein weiteres Becheraufnahmeteil 32 mit entsprechenden Formeintiefungen 7' und am Oberteil 9 ein Becherabdeckteil 9' mit steuerbsrer Zuleitung 35 für das sterilisierende Medium vorgesehen.According to Fig. 2 is to carry out the independent process solution behind the deep-drawing station 4 ', which is designed here in the usual way, that is to say mkt The male part 3 and the female part 34 work, and another cup-receiving part on the lower part 8 32 with corresponding shape recesses 7 'and on the upper part 9 a cup cover part 9 'provided with a controllable supply line 35 for the sterilizing medium.

Eine Nachapülung mit keimfreier und trockner Luft kann hierbei natürlich auch ohne weiteres vorgesehen werden. L e e r s e i t eA post-purging with sterile and dry air can of course be done here can also be provided without further ado. L e r s e i t e
