Further, when the food is separated, the depth of the groove 51 is made as deep as possible in order to reduce the resistance to the food. However, if the groove 51 is made too deep, the strength of the intake portion 2 may not be maintained, and it may be difficult to place food on the intake portion 2. Therefore, the depth is preferably set so as not to exceed the central vertical axis CL.
