HETEROGENEOUS MATERIAL STORAGE UNIT HAVING A SEPARATE SEALING COVER TO IMPROVE SEALING PROPERTIES

摘要

A heterogenous material storage unit having a sealing cover is provided to drop contents from a storage space which is open when an operation part is pulled in an upward direction or twisted. A heterogeneous material storage unit(1) comprises a fixed part(10) and an operation part(20). An inlet(11) is formed at the upper end of the fixed part, and a projection(12) is extended from the lower end of the unit. A storage space(22) and a longitudinally extended tube(21) are formed around the inlet. The tube is adhered to an inner wall of the inlet to create an air-tight state. When the operation part is lifted up, an outlet passage(24) with an outlet hole(23) for communication with the outside air and the inside of the container is formed. The lower end of the tube is air-tightly shut by a sealing cover(30). The sealing cover is removed from the tube when the operation part is lifted up, or rotates several times, being stopped by the projection.
