PROTECTED KETTLE WHICH PROVIDES REASONABLE PROTECTION AGAINST THE ACCIDENTAL OUTBURST OF POTENTIALLY DANGEROUS LIQUIDS, OR BOILED LIQUIDS, AND ENABLES THEIR CONTROLLED POURING

摘要

A safety device for a liquid-containing vessel for preventing accidental spilling of the liquid contained in the vessel, the liquid having a rest level. The safety device comprises a lid assembly having a lower partition, the partition dividing the vessel into a first lower liquid containing portion and a second upper portion empty from liquid and having a second liquid opening, the lower partition comprising a movable flap and a first liquid opening that is located lower than and below the second liquid opening in an upright position of the vessel, the flap having positive magnetic attraction with the first liquid opening and being configured to seal the first liquid opening against passage of the liquid. In an upright position of the vessel, the entire safety device is located higher than and above the rest level of the liquid and the flap is normally open with respect to the first liquid opening. In a tilted position of the vessel, where the level of the liquid forms an acute angle with the first liquid opening that is larger than a given minimal operating angle, the flap closes and seals the first liquid opening at least under the hydrostatic force of the liquid and remains in a closed position at least by the positive magnetic attraction with the first liquid opening.
