Ventil-Membran-Mechanismus zum Erhalt eines konstanten PartialdrucJces von Gasen in abgefüllten Flüssigkeiten bei teilweiser Entleerung des Behältnisses.Valve-diaphragm mechanism for maintaining a constant partial pressure of gases in filled liquids when the container is partially emptied.
Stand der TechnikState of the art
Eine 1000, 2000 und mehr ml fassende Getränkeflasche besteht in üblicher Bauform aus dem Behältniss in den unterschiedlichsten Formen und dem Verschluß.A beverage bottle with a capacity of 1000, 2000 or more ml usually consists of a container in a variety of shapes and a closure.
Problemproblem
Der im Anspruch 1 angegebenen Erfindung liegt das Problem zugrunde, daß ein Getränk relativ schnell seine orginale Frische und den Geschmack verliert, wenn es halb geleert und verschlossen steht ( in Abhängigkeit von der Umgebungstemperatur schneller oder langsamer).Das in der Flüssigkeit gelöste Gas entweicht teilweise und vermischt sich mit der beim Teilentleeren eingedrungenen Luft.Der Flüssigkeitsrest ist in seiner Zusammensetzung abweichend vom Orginalzustand.Das Getränk wird schal.The invention specified in claim 1 is based on the problem that a drink loses its original freshness and taste relatively quickly when it is half empty and left closed (faster or slower depending on the ambient temperature). The gas dissolved in the liquid partially escapes and mixes with the air that has entered when the container is partially emptied. The composition of the remaining liquid differs from the original state. The drink becomes stale.
Dieses Problem wird mit den Maßnahmen des Anspruches 1 gelöst.This problem is solved by the measures of claim 1.
Vorteilhafte Wirkung der ErfindungAdvantageous effect of the invention
Mit der Erfindung wird erreicht, daß kein Konzentrationsaustausch entlang des Konzentrationsgefälles der in der Flüssigkeit gelösten Gase und der bei der Teilentleerung des Behältnisses eingetretenen Luft erfolgen kann.The invention ensures that no exchange of concentration can occur along the concentration gradient of the gases dissolved in the liquid and the air that has entered during the partial emptying of the container.
Darstellung der ErfindungDescription of the invention
Ein Ausführungsbeispiel der Erfindung wird anhand der Figur 1 und 2, ein weiteres anhand der Figuren 3 und 4 erläutert.Das Erste zeigt:One embodiment of the invention is explained using Figures 1 and 2, another using Figures 3 and 4. The first shows:
Fig.l das Behältniss im Ausgangszustand, geschlossen (inFig.l the container in its initial state, closed (in
diesem Falle eine Flasche )
Fig.2 das Behältniss nach der Teilentleerung im geschlossenen Zustandin this case a bottle)
Fig.2 the container after partial emptying in the closed state
das zweite Beispiel zeigt:
Fig.3 siehe Fig.lthe second example shows:
Fig.3 see Fig.l
(in diesem Falle ein Standbehältniss z.b.ein Faß )
Fig.4 siehe Fig.2(in this case a container such as a barrel)
Fig.4 see Fig.2
Figur 1 und 2 stellen eine Mehrwegflasche aus Plaste mit
Schraubverschluß dar. Am Flaschenboden ist ein Ventil eingearbeitet, welches Luft nach innen läßt, nach außen zu jedoch
luftdicht schließt ( mehrere Bauformen möglich)( 4). Zirkulär am Boden ist die zusammengefaltete bzw. dehnbare undurchlässige
Membran dergestalt angebracht, daß sie sich luftdicht schließend in das Flascheninnere wölbt und der Flascheninnenseite anliegt (
3). Wird nun der Verschluß der Flasche ( 2) geöffnet und ein Teil der Flüssigkeit ( 8) ausgekippt, gelangt eine etwa gleichgroße
Menge Luft (7) durch das Ventil in den von der Membran
abgeschlossenen Anteil der Flasche. Da sich die Membran durch den beim Ausgießen der Flüssigkeit entstehenden Unterdruck entfaltet
wird gleichfalls die Luft durch das Ventil angesaugt. Wird die Flasche nun abgesetzt, drückt die Flüssigkeit auf die Membran.
Der Druck wird über die nun in der Flasche befindlichen Luft weitergeleitet und das Ventil am Flaschenboden schließt. Wird
die Flasche nun geschlossen kann kein Konzentrationsaustausch zwischen der in der Flasche befindlichen Luft und dem in der
Flüssigkeit gelösten Gas stattfinden.Figures 1 and 2 show a reusable plastic bottle with a screw cap. A valve is incorporated into the bottom of the bottle, which allows air to enter but is hermetically sealed to the outside (several designs possible) (4). The folded or stretchable impermeable membrane is attached to the bottom in a circular manner in such a way that it curves into the inside of the bottle, sealing it hermetically and resting against the inside of the bottle (3). If the bottle cap (2) is now opened and part of the liquid (8) is tipped out, an approximately equal amount of air (7) passes through the valve into the space covered by the membrane.
closed part of the bottle. As the membrane unfolds due to the negative pressure created when the liquid is poured out, the air is also sucked in through the valve. If the bottle is now put down, the liquid presses on the membrane. The pressure is passed on via the air now in the bottle and the valve at the bottom of the bottle closes. If the bottle is now closed, no exchange of concentration can take place between the air in the bottle and the gas dissolved in the liquid.
Fig. 3 und 4 stellt denselben Wirkungsmechanismus anhand eines faßartigen Behältnisses dar, bei welchem die Flüssigkeit an einem unten angebrachten Hahn abgezapft wird. In gleichem Maße wie Flüssigkeit austritt, wird Luft durch das Ventil ( 4) angesaugt ( 7) und gelangt in den durch die Membran ( 3) abgetrennten Anteil des Behältnisses. Wird der Hahn geschlossen, kann ebenfalls kein Gasaustausch mehr erfolgen. Das Ventil muß einen größeren Durchmesser haben als der Ausfluß, damit keine Luft durch die Ausflußöffnung angesaugt wird.Fig. 3 and 4 show the same mechanism of action using a barrel-like container, in which the liquid is drawn off from a tap at the bottom. As liquid comes out, air is sucked in through the valve (4) (7) and reaches the part of the container separated by the membrane (3). If the tap is closed, gas exchange can no longer take place. The valve must have a larger diameter than the outlet so that no air is sucked in through the outlet opening.
