TODAY’S PATENT – FOOD MIXER
The Food Mixer was invented by Masayasu Kurachi, Atsushi Takahara, Hideto OMI on December 31, 2020 bearing patent number US20200404929A1.
A food mixer comprises a container, a rotational shaft, an agitation member, a main packing, a collar, and a sub packing. The rotational shaft penetrates a wall of the container and is rotatably supported by the container. The agitation member is configured to agitate a work product in the container by rotating together with the rotational shaft. The main packing is disposed between the container and the rotational shaft. The collar is held at an outer periphery of the rotational shaft by a fixing member so that a space is formed between the main packing and the collar. The collar allows the space to be opened toward the container when the collar moves away from the fixed position after the fixing state is removed. The sub packing is provided between an outer periphery of the collar and a boss portion.
