摘要:
A filtering discharge container employing a delaminatable bottle was provided, which reliably prevents a content liquid from leaking out before the first use, and reduces a discharging resistance during the second and subsequent use. An engagement portion (31c) is provided in an outlet passage of a mouth cap (3). A plug (34) is engaged with the engagement portion (31c) in such a manner that the plug (34) can be disengaged from the engagement portion (31c) by an internal pressure of an inner layer bag (22) increased by squeeze-deforming a body of an outer layer bottle (21). The outlet passage is closed with the plug (34) engaged with the engagement portion (31c). After the plug (34) is disengaged from the engagement portion (31c), liquid communication is established between the inside of the inner layer bag (22) and a filter (33).
