PROBLEM TO BE SOLVED: To provide a discharge product which includes a new structure and enables a user to check the residual quantity of a content.SOLUTION: A discharge product 10 includes: an outer container 11; two flexible inner containers 12 housed in the outer container 11; and a valve assembly 13 which closes the outer container 11 and allows the interior of the two inner containers 12 and outer air to communicate with each other or shields the interior of the two inner containers 12 from the outer air. The two inner containers 12 contact with each other so that a contact line X vertically extending is formed in an expansion state where an undiluted solution is stored therein. Further, the two inner containers 12 are separated from each other so that the contact line X disappears in a contraction state where the undiluted solution is discharged. A user can check the residual quantity of the undiluted solution by visually checking a state of the contact line X from a window part 15 of the outer container 11.SELECTED DRAWING: Figure 1 |
