PROBLEM TO BE SOLVED: To disperse inclusions such as petals and gold pigments or the like in the content of a container main body clogged at an extremity end of a content inflow tube.SOLUTION: A cylinder 8 includes: a downstream side storing area A between a discharge valve 5 and a cup rubber 6 acting as a sucking check valve; an upstream side storing space area B at an upstream side of the cup rubber 6; and a lower end side cylinder part 8c for fixing a tube 9 to an upstream side of the upstream side storing area B. Pistons [2+3+4] cooperated with an operation button 1 include an upstream side piston member 4 moving while closely contacting with an inner peripheral surface of the cylinder 8 constituting the upstream side storing space B. Depressing the operation button 1 causes the content in the downstream side storing area A to be discharged into an outside area through a moving valve member 5 in an open state and the content in the upstream side storing area B to flow in reverse toward the tube 9 due to motion of the piston member 4, and the gold pigments 10b clogged at a mesh bushing 9b at the extremity end of the tube 9 are returned back into a container main body 10.SELECTED DRAWING: Figure 2 |
