It is an object of the present invention to provide an agitating device which can be shaken to agitate, whip, froth and disperse the liquid material content.

There is provided a device for mixing liquid material comprising: a container containing liquid material; an opening-closing member formed on the top of said container; and a coil spring accommodated in said container and having an end fixed on the upper part of said container so as to be vibrable and oscillable. The coil spring has a smaller coil pitch in its lowest part than that in its upper part.

Apparatus for mixing culinary ingredients including a container with a lid and mixer with fingers are disclosed. Methods of mixing culinary ingredients using apparatus are also disclosed.

The stirring utensil may comprise a stirring disc, a handle, and a ball and socket joint. The stirring disc may detachably couple to the handle via the ball and socket joint. The stirring utensil may be adapted for a user to stir non-solid food to mix the non-solid food and to separate lumps from the bottom of a pot. As non-limiting examples, the non-solid food may be soup, sauce, or gravy. The stirring disc may make contact with the bottom of the pot to separate the non-solid food from the pot in order to prevent the non-solid food from scorching. The stirring disc may be elevated above the bottom of the pot to mix the non-solid food at all depths. The ball and socket joint may enable the stirring disc to rotate and tilt while stirring.

Apparatus for mixing culinary ingredients including a container with a lid and mixer with fingers are disclosed. Methods of mixing culinary ingredients using apparatus are also disclosed.

Proposed is a vertically movable mixer including a container comprising a bottom portion in which a central through-hole is formed, a motor housing coupled to the container under the container, a motor built in the motor housing, a sliding member configured to reciprocally slidably move in a vertical direction through the central through-hole of the container, a rotatable shaft rotatably installed in the sliding member so as to be configured to reciprocally slidably move in the vertical direction in conjunction with the sliding member and axially mounted on a motor shaft of the motor so as to be configured to rotate by rotation of the motor, and a rotatable blade mounted on the rotatable shaft and configured to cut, grind, and mill food contained in the container while rotating and while reciprocally slidably moving in the vertical direction.
