Abstract

To avoid droplet formation at pouring apertures for liquids, a liquid-repellent material is provided for the pouring aperture or for its coating.

Description

Die Erfindung basiert auf der Erkenntnis, daß die beim Ausgie­ ßen von Flüssigkeiten wie z.B. Kaffee, Tee schwer zu vermeiden­ de Tropfenbildung auf der starken Adhäsion (Benetzbarkeit) zwi­ schen der auszugießenden Flüssigkeit und dem Gefäßrandmaterial bzw. dem Material am Ende eines Ausgußrohrs des Gefäßes besteht. Durch einen einfachen Versuch kann man sich leicht hiervon über­ zeugen. Bestreicht man z.B. die Ausgußöffnung einer stark trop­ fenden Kaffeekanne mit Kerzenwachs (Paraffin), so ist die Trop­ fenbildung und das Herunterlaufen von Tropfen am Ausgußrohr so­ fort unterbunden. Da Kerzenwachs oder Fette wie Vaseline etc. trotz guter Eigenschaften bei der Vermeidung einer Tropfenbil­ dung wenig beständig, d.h. nicht spülfest sind, werden in der vorliegenden Erfindung insbesondere Ausgußöffnungen oder deren Beschichtung aus flüssigkeitsabstoßenden (spülfesten) und wär­ mebeständigen Materialien wie z.B. Polytetrafluorethylen PTFE, Polyvinylidenfluorid PVDF oder Polyethylen PE vorgesehen.The invention is based on the knowledge that when pouring eating liquids such as Coffee, tea difficult to avoid de Drop formation on the strong adhesion (wettability) between the liquid to be poured out and the rim of the vessel or the material at the end of a pouring tube of the vessel. You can easily get over this by a simple experiment testify. If you paint e.g. the spout of a strongly trop The coffee pot with candle wax (paraffin) is the trop so formation and the running of drops on the pouring spout prevented further. Since candle wax or fats like petroleum jelly etc. despite good properties in avoiding a drop bil less stable, i.e. are not washable, are in the present invention, in particular spout openings or their Coating made of liquid-repellent (rinse-proof) and warm resistant materials such as Polytetrafluoroethylene PTFE, Polyvinylidene fluoride PVDF or polyethylene PE is provided.

In entsprechender Weise kann auch die Tropfenbildung beim Aus­ gießen anderer Flüssigkeiten durch geeignete flüssigkeitsabstos­ sende Materialien oder Beschichtungen der Ausgußöffnungen ver­ mieden werden.In a corresponding manner, the formation of drops when off pour other liquids using suitable liquid repulsions ver sending materials or coatings of the spout be avoided.

Die Erfindung kann sowohl bei Ausgußöffnungen, die Teil des Ge­ fäßrandes sind, als auch bei Öffnungen von Ausgußrohren von Flüs­ sigkeitsgefäßen eingesetzt werden.The invention can be used for pouring openings that are part of the Ge are edge of the barrel, as well as openings of pouring pipes from rivers liquid vessels are used.
