Abstract

PURPOSE:To effectively set a creamer vessel and to effectively prevent rotation by bringing a guide wall stood substantially in the half circumference of a hole of a cover into contact with the inner peripheral wall of a recess of a creamer body to restrict rotation of the cover, and providing a connector for connecting a plurality of protrusions formed on the outer peripheral edge of the cover and a L-shaped piece at the vessel. CONSTITUTION:Material is gradually solidified, since agitating while cooling, cream material is solidified to an agitating fan 5, and a reverse rotary force to the fan 5 is generated at a creamer vessel 6 by its reaction force. The guide wall 8d of a cover 8 is brought into contact with the inner peripheral wall 3c of the recess 3b of a creamer body to prevent it from rotating. The cover 8 and the vessel 6 are connected to the L-shaped piece 8d of the cover, protrusions 8c are connected to a bag part 13b and a recess 14a of a frame 13 and a handle 14 to prevent them from reversely rotating of the fan 5. Since the frame 13 is so caulked that the whole upper periphery is brought into close contact with the vessel 6, even if rotating motion of the fan 5 is applied to the vessel 6 and the frame 13, it does not rotate due to slip.
