Description

  The present invention relates to a stirring rod for stirring and mixing a liquid or powder and a stirrer equipped with the stirring rod.

  Conventionally, for example, when preparing a glaze, the raw material of a glaze is put into the container made from a vinyl chloride, it stirs with a stirrer, and it mixes and prepares a component. As such a stirrer, there is a type equipped with a stirring blade in a container (for example, Japanese Patent Application Laid-Open No. 2003-159523). Various types (for example, Japanese Patent Application Laid-Open No. 2001-224940) have been proposed in which an agitation rod provided is mounted and an operator holds and agitates a main body provided with a driving means.

However, in the case of the former stirrer, there is no problem because the rotation position of the stirring blade in the container is determined in advance, but in the case of the latter stirrer, the stirring blade often contacts the inner surface of the container during stirring. There is a problem that the container is damaged by the contact, and the container composition (vinyl chloride) scraped by the contact is mixed in the glaze.
