Abstract:
In a filtering dispenser container which includes a plug attached to a mouth portion of a bottle thereof and having a liquid discharge passage, and a filter and a check valve provided in the discharge passage, air lock is prevented, even if the container contains a highly percolative liquid, by preventing a very small amount of liquid percolating the check valve from reaching the filter. In the filtering dispenser container, a dam (14) is provided between the check valve (23) and the filter (25) for retaining a very small amount of the liquid percolating the check valve (23) when the check valve is closed. Thus, the filter (25) is prevented from being wetted with the liquid percolating the closed check valve (23) during storage or delivery of the container before the first use of the container.
