Abstract

A refillable container including an outer container (3), a lid member (4), an inner container (5), and a pump (6). The outer container has an opening formed in an upper part thereof, and the lid member is configured to close the opening of the outer container. The inner container is made of paper, configured to store the liquid content therein, and replaceably accommodated in the outer container. The pump is configured to pump up the liquid content in the inner container stored in the outer container and to dispense the liquid content outside of the refillable container. When the opening of the outer container is closed by the lid member, a suction tube (15) of the pump, which is arranged below the lid member, is inserted from a suction port (8), which is formed in an upper surface of the inner container, into the inner container.
