Title: Automatic pull-out and closing device
Inventor: ZIMMER PETER
IPC: B65D47/06
Filed: 1981-02-24
Abstract: Drinks which have been brought to a particular temperature must, if the desired temperature is to be preserved over a relatively long period, be stored in thermos flasks, the seals of which are designed as screws. When such drinks are poured out, the aforementioned seals must always be screwed open and closed. In this process, it frequently happens that the thermos containers are not properly sealed, which results in unintended temperature loss. According to the invention, an automatic pouring-out and closing device is produced, and illustrated in the attached drawing, to ensure that a thermos flask is opened and closed automatically. A ball (8) is arranged in the funnel-shaped interior (5) of the automatic device. During the pouring-out process, the ball (8) rolls across the running webs (9) towards the lid (6). The liquid simultaneously reaches the spout (4) via the through-flow apertures (7 and 10). After pouring out, the ball (8) rolls back onto the through-flow aperture (7) and recloses the thermos flask in an airtight manner. The automatic device is preferably intended for use with thermos flasks, but it can also be used with other liquid containers. <IMAGE>
