Description
Gaspolsterkissen Die Erfindung betrifft Gaspolsterkissen, wie sie für die Verpackung verschiedener Güter, z. B. Maschinen, Meßinstrumente usw., insbesondere für den Überseetransport, verwendet werden.Gas Pillows The invention relates to gas pillows such as these for the packaging of various goods, e.g. B. machines, measuring instruments, etc., in particular for overseas transport.
Die bekannten Gaspolsterkissen dieser Art bestehen aus verschweißten Kunststoff-Folien, vorzugsweise aus Polyvinylchlorid, und besitzen eine Füllung aus Luft. Nachteilig ist hierbei, daß die Folie nicht mit vertretbarem Aufwand gasdicht hergestellt werden kann; vielmehr tritt bei Belastung Luft infolge Diffusion nach außen. Bei 200 C und 10 kg Belastung kann ein 10. 10 cm großes Kissen aus 0,4 mm PVC-Folie etwa 1 cm3 Luft je Tag verlieren. The known gas cushion cushions of this type consist of welded Plastic films, preferably made of polyvinyl chloride, and have a filling from air. The disadvantage here is that the film is not gas-tight with a reasonable amount of effort can be produced; rather, air occurs after exposure as a result of diffusion Outside. At 200 C and a load of 10 kg, a 10.10 cm cushion made of 0.4 mm PVC film lose about 1 cm3 of air per day.
Erfindungsgemäß kann die Polsterwirkung über einen wesentlich längeren Zeitraum aufrechterhalten werden, wenn dafür gesorgt wird, daß im Füllgas der Partialdruck mindestens eines in der umgebenden Atmosphäre vorhandenen Gasbestandteils kleiner ist als in dieser Atmosphäre. Vorzugsweise ist im Füllgas der Partialdruck von Stickstoff und/oder Sauerstoff kleiner als in der Luft. According to the invention, the cushioning effect can last for a significantly longer period Period of time can be maintained if it is ensured that the partial pressure in the filling gas at least one gas component present in the surrounding atmosphere is smaller is than in this atmosphere. The partial pressure of nitrogen is preferably in the filling gas and / or oxygen less than in air.
Da die Diffusionsgeschwindigkeit eines Gases durch eine Folie weniger von den Gesamtdruckverhältnissen beeinflußt wird, sondern im wesentlichen vom Unterschied der Partialdrücke dieses Gases zu beiden Seiten der Folie abhängt, tritt bei dem erfindungsgemäß ausgebildeten Gaspolsterkissen nicht nur Gas aus dem Füllraum nach außen, sondern umgekehrt auch ein anderes Gas von außen in den Füllraum hinein. Auf diese Weise ist es möglich, den Gasverlust des Kissens zu verringern und die Polsterwirkung über einen längeren Zeitraum als bisher aufrechtzuerhalten. Unter gewissen Umständen kann man sogar erreichen, daß das Produkt aus Gesamtdruck und Volumen des Gases im Kissen etwa gleich groß bleibt oder sich im Laufe der Zeit sogar erhöht. Because the rate of diffusion of a gas through a film is less is influenced by the overall pressure conditions, but essentially by the difference the partial pressures of this gas depends on both sides of the film, occurs in the According to the invention designed gas cushion not only after gas from the filling space outside, but vice versa also another gas from outside into the filling space. In this way it is possible to reduce the gas loss of the cushion and the Maintain the cushioning effect over a longer period of time than before. Under Under certain circumstances one can even achieve that the product of total pressure and Volume of gas in the pillow remains about the same or changes over time even increased.
Bei einem bevorzugten Ausführungsbeispiel besteht die Kissenfolie aus einem Material, das gegenüber dem Gas kleineren Partialdrucks eine größere Durchlässigkeit besitzt als gegenüber wenigstens einem Teil des übrigen Füllgases. Auf diese Weise kann man auch bei relativ kleinem Partialdruckunterschied des von außen nach innen diffundierenden Gases Gasverluste in einem stärker belasteten Kissen ausgleichen. In a preferred embodiment, the pillow sheet is made made of a material that has a greater permeability than the gas with a lower partial pressure possesses than opposite at least part of the remaining filling gas. In this way can also be achieved with a relatively small difference in partial pressure from the outside to the inside diffusing gas compensate for gas losses in a more heavily loaded cushion.
Der kleinere Partialdruck innerhalb des Kissens ist vorzugsweise Null. Dies ist immer dann gegeben, wenn die Füllung nur aus einem einzigen Gas besteht, auch wenn es sich um ein in der Luft vorhandenes Gas handelt, also Stickstoff, Sauerstoff oder Kohlendioxyd. In jedem Fall besteht hinsichtlich der jeweils anderen Luftbestandteile ein Partialdruck- gefälle in das Kissen hinein. Wenn die Füllung aus einem Gasgemisch besteht, sollte dafür gesorgt werden, daß wenig oder kein Stickstoff und/oder Sauerstoff darin enthalten ist. The smaller partial pressure within the cushion is preferred Zero. This is always the case when the filling consists of only one gas, even if it is a gas that is present in the air, i.e. nitrogen, oxygen or carbon dioxide. In any case, there is air constituents with regard to the other in each case a partial pressure slope into the pillow. When the filling consists of a gas mixture care should be taken to have little or no nitrogen and / or oxygen is included.
Besondere Vorteile bietet es, wenn das Füllgas wenigstens teilweise aus größeren Molekülen als Stickstoff oder Sauerstoff besteht, beispielsweise von einem der als Kältemittel bekannten halogenisierten Kohlenwasserstoffe gebildet wird. Das Füllgas kann dann infolge der größeren Moleküle schlechter durch die Folie nach außen diffundieren als umgekehrt der Stickstoff oder Sauerstoff der Luft nach innen. In diesem Zusammenhang kann man Kunststoff-Folien verwenden, die bisher wegen ihrer hohen Luftdurchlässigkeit für Luftpolsterkissen nicht angewendet werden konnten. Unter gewissen Umständen kann sogar eine hohe Luftdurchlässigkeit erwünscht sein. It offers particular advantages if the filling gas is at least partially consists of larger molecules than nitrogen or oxygen, for example of one of the halogenated hydrocarbons known as refrigerants will. Because of the larger molecules, the filling gas can then pass through the film more poorly diffuse outwards than, conversely, nitrogen or oxygen in the air Inside. In this context you can use plastic foils, which were previously due to their high air permeability for air cushions could not be used. Under certain circumstances, a high level of air permeability may even be desirable.
In der Zeichnung ist ein Gaspolsterkissen veranschaulicht, das aus einem Schlauch 1 aus PolyvinyI-chlorid hergestellt und an den beiden Stirnseiten durch Schweißnähte 2 und 3 verschlossen ist. Die Gasfüllung des Kissens besteht bei diesem Ausführungsbeispiel aus einem einzigen Gas, nämlich Difluordichlormethan. In the drawing, a gas cushion is illustrated, which consists of a tube 1 made of polyvinyl chloride and made on the two end faces is closed by welds 2 and 3. The cushion is filled with gas in this embodiment from a single gas, namely difluorodichloromethane.
