Abstract:
A filter-equipped container which, particularly in a small-sized eyedrop bottle or the like, is capable of accurate dropping while preventing bubbles from being involved when a contents liquid is to be delivered through a delivery port. To solve such problem, a plug body 12 disposed in the mouth of a bottle 10 is provided with a delivery passage for delivering contents liquid received in the bottle 10, the delivery passage being provided with a filter 25. The filter 25 is composed of a filter film 25a for filtering bacteria to prevent the latter from permeating from upstream to downstream as seen in the direction of delivery, and a contents liquid holding member 25b of porous material that has microscopic pores, disposed upstream of the filter film 25a, the contents liquid holding member 25b being in planar contact with the filter film 25a.
