Abstract

A method for producing a packaging which is filled with liquid is proposed in which the pack is molded from a semirigid sealable packaging material. To increase the drop resistance and impact resistance of the pack, a partial vacuum is generated in the latter, so that its walls are arched inwards.

Description

Verfahren zum Herstellen einer mit Flüssigkeit gefüll-Method for producing a liquid-filled

ten, halb steifen Verpackung Stand der Technik Die Erfindung geht aus von einem Verfahren nach der Gattung des Hauptanspruchs. Es sind bereits mehrere Verfahren und Vorrichtungen zum Herstellen von mit Flüssigkeit gefüllten Verpackungen bekannt, die ganz oder teilweise aus halbsteifen Packstoffen, wie mit einem siegelbaren kunststoffbeschichteten Karton oder ähnlichen Laminaten geformt sind. Diese Verpackungen haben an den Verbindungen und Verschlüssen heißgesiegelte oder geschweißte Siegelnähte, deren Festigkeit gegenüber der des Packstoffes vermindert ist. Bei Stoßeinwirkung auf eine solche Packung oder bei Herabfallen einer solchen aus einem Verkaufsregal kann eine solche Siegelnaht durch den plötzlich auftretenden Druckaufbau in der nicht steifen Verpackung aufplatzen. Es ist daher wünschenswert die Fall-und Stoßfestigkeit halbsteifer Verpackungen zu erhöhen.th, semi-rigid packaging prior art The invention works from a method according to the preamble of the main claim. There are already several Methods and devices for the production of packaging filled with liquids known to be wholly or partially made of semi-rigid packaging materials, such as with a sealable plastic-coated cardboard or similar laminates are molded. This packaging have heat-sealed or welded sealing seams on the connections and fasteners, whose strength is reduced compared to that of the packaging material. With impact on such a pack or if it falls off a sales shelf such a sealed seam can occur due to the sudden build-up of pressure in the do not burst open stiff packaging. It is therefore desirable to have the drop and impact resistance to increase semi-rigid packaging.

Vorteile der Erfindung Das erfindungsgemäße Verfahren mit den kennzeichnenden Merkmalen des Hauptanspruchs hat den Vorteil, daß, da durch den Unterdruck der Verpackung die halbsteife Wandung nach innen gewölbt ist, bei Stoßeinwirkung zunächst Energie für die Beseitigung der nach innen gerichteten Wölbung verzehrt wird, ehe in der Packung ein zum Platzen führender Überdruck erzeugt wird. Ein günstiger Nebeneffekt des Unterdrucks ist, daß durch die nach innen gerichtete Wölbung der Packungswände die Griffigkeit der Packung gesteigert ist gegenüber einer solchen Pakkung, deren Wandung nach außen gewölbt ist.Advantages of the invention The method according to the invention with the characterizing Features of the main claim has the advantage that, because through the Under pressure of the packaging the semi-rigid wall is curved inwards, when impacted First of all, energy is consumed in removing the inwardly directed bulge before an overpressure leading to bursting is generated in the pack. A cheaper one Side effect of the negative pressure is that the inward curvature of the Pack walls the grip of the pack is increased compared to such Package, the wall of which is curved outwards.

Beschreibung der Erfindung Maßnahmen zum Erzeugen von Unterdruck in einer Verpakkung aus einem halbsteifen Packstoff sind: a) Verformen der Verpackung bzw. eines Teils deren Wandung nach dem Füllen mit einer Flüssigkeitsmenge im Sinne einer Verkleinerung des Fassungsvolumens der Packung vor dem Verschließen, mit der Folge, daß die Verpackung wieder ihre Idealform einnehmen will.Description of the invention Measures for generating negative pressure in A package made from a semi-rigid packaging material is: a) Deforming the package or a part of its wall after filling with an amount of liquid in the sense a reduction in the volume of the pack before closing, with the The result is that the packaging wants to resume its ideal shape.

b) Einführen von Wasserdampf in den Kopfraum der Verpackung vor oder beim Verschließen der Verpackung; durch Kondensation des Wasserdampfes wird in der Verpackung ein Unterdruck erzeugt, durch den die Wandung der Verpackung nach innen verwölbt wird.b) Introduction of water vapor into the headspace of the packaging in front of or when closing the packaging; by condensation of the water vapor in the Packaging creates a negative pressure through which the wall of the packaging inward becomes arched.

c) Einführen eines Gases, beispielsweise Kohlendioxyd, in die Flüssigkeit und/oder in den Kopfraum der Verpackung vor oder beim Verschließen der Verpackung; es wird ein Gas ausgewählt, das von der Flüssigkeit absorbiert wird, so daß in der Verpackung ein Unterdruck entsteht.c) Introducing a gas, for example carbon dioxide, into the liquid and / or in the head space of the packaging before or when the packaging is closed; a gas is selected which is absorbed by the liquid so that in the Packaging creates a vacuum.

d) Heißabrüllen der Flüssigkeit und Verschließen der Verpackung vor Abkühlen der Flüssigkeit; durch die mit der Abkühlung verbundene Kontraktion der Flüssigkeit und des Gases im Kopfraum entsteht in der verschlossenen Packung ein Unterdruck.d) Hot filling of the liquid and sealing of the packaging Cooling the liquid; due to the contraction of the Liquid and the gas in the head space is created in the sealed pack Negative pressure.

Beim Durchführen einer oder zugleich mehrerer solcher Maßnahmen vor oder beim Verschließen von Verpackungsbehältern aus einem halbsteifen Packstoff wird eine nach innen gerichtete Wölbung der Packungswandung oder Packungswände bzw. ein Unterdruck in der Verpackung erzeugt. Die Fallhöhe einer derart hergestellten Pakkung ist um 100 bis 200 % höher gegenüber einer solchen ohne Unterdruck.When performing one or more such measures at the same time or when closing packaging containers made from a semi-rigid packaging material an inward curvature of the packing wall or packing walls or creates a vacuum in the packaging. The height of fall of a manufactured in this way Packing is 100 to 200% higher than one without negative pressure.
