Patent ID: 7654420

Claim:
A discharge container, comprising: a cylindrical container body with a bottom ( 1 ) which includes a cylindrical wide opening ( 2 ) disposed at the top end of the container body ( 1 ), a support ( 6 ) extending upward from a bottom wall ( 3 ) along a center axis, and a fixed partitioning plate ( 7 ) extending from a region from a peripheral wall ( 4 ) to a bottom wall ( 3 ) as a base end to partition the inside of the container body ( 1 ) in a radial direction; a rotor ( 11 ) which includes a cylindrical shaft piece ( 12 ) rotatably engaging with the outer surface of the support ( 6 ), and a rotatable partitioning plate ( 13 ) extending from the cylindrical shaft piece ( 12 ) as a base end to be arranged in a radial direction along with the fixed partitioning plate ( 7 ); and a cylindrical lid with a top ( 20 ) which has a top wall ( 32 ) having a saucer-shaped upper surface, and a downwardly extending shaft ( 23 ) extending downwardly from the lower surface of the top wall ( 32 ) and engaging with the inner surface of the cylindrical shaft piece ( 12 ) from above such that the downwardly extending shaft ( 23 ) cannot rotate therein, the lid ( 20 ) covering the cylindrical opening ( 2 ) as a lid and rotatably engaging with the cylindrical opening ( 2 ), wherein: the edge of the fixed partitioning plate ( 7 ) is brought into sliding contact with the cylindrical shaft piece ( 12 ); the edge of the rotatable partitioning plate ( 13 ) is formed by a spatula-shaped sliding member ( 14 ) made of soft material and is brought into sliding and linear contact with an area from the peripheral wall ( 4 ) to the bottom wall ( 3 ) of the container body ( 1 ); the lower surface of the top wall ( 32 ) is brought into sliding contact with the upper end surfaces of the cylindrical opening ( 2 ) and the fixed partitioning plate ( 7 ) and brought into contact with the upper end surface of the rotatable partitioning plate ( 13 ); an storage chamber (R) is formed by the fixed partitioning plate ( 7 ), the rotatable partitioning plate ( 13 ), the peripheral wall ( 4 ), the bottom wall ( 3 ), the cylindrical shaft piece ( 12 ), and the top wall ( 32 ); a discharge opening ( 33 ) communicating with the storage chamber (R) is provided on the top wall ( 32 ); and the capacity of the storage chamber (R) is reduced by decreasing a central angle between the fixed partitioning plate ( 7 ) and the rotatable partitioning plate ( 13 ) by the relative rotation between the container body ( 1 ) and the lid ( 20 ), whereby contents within the container are pressed and discharged from the discharge opening ( 33 ) to the upper surface of the top wall ( 32 ).
