Title:

FILTER-EQUIPPED CONTAINER

Document Type and Number:

WIPO Patent Application WO/2005/044689

Kind Code:

A1

Abstract:

This invention provides 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 disposed upstream of the filter film (25a), the contents liquid holding member (25b) being in planar contact with the filter film (25a).
