Claims20
A microkettle, comprising:
- a vessel having a floor and upwardly extending sidewalls defining an interior volume;
- a cup handle positioned on an outer portion of the vessel;
- a lid pivotally attached to the vessel at a pivot location, the lid having a lid lever operable to pivot the lid between a closed position in which the lid encloses the interior volume and an open position in which the lid is rotated to enable access to the interior volume;
- and
- an insert attached to the lid and extending into the interior volume when the lid is in the closed position, the insert having one or more channels and one or more ribs configured to provide nucleation sites to facilitate boiling when a liquid is heated in the vessel.

A microkettle, comprising:
- a vessel having a floor and upwardly extending sidewalls defining an interior volume, the sidewalls terminating in an open-topped rim of the vessel;
- a cup handle positioned on an outer portion of the vessel;
- a lid pivotally attached to the vessel at a pivot location located at a juncture of the vessel sidewall and the cup handle, the lid having a lid lever operable to pivot the lid between a closed position in which the lid encloses the interior volume and an open position in which the lid is rotated to enable access to the interior volume;
- and
- an insert attached to an interior surface of the lid at a mount and extending into the interior volume when the lid is in the closed position, the insert being configured to provide nucleation sites to facilitate boiling when a liquid is heated in the vessel, the insert further extending into the interior volume when the lid is in the open position.
