A water-dispersible sheet is described that maintains water dispersibility while providing suppressed time degradation of the tacky adhesiveness of a tacky adhesive layer. The water-dispersible sheet has a paper substrate with a multilayer structure. One layer of the multilayer structure is an inner layer that is not in contact with the tacky adhesive layer. Another layer is a surface layer that is in contact with the tacky adhesive layer. The layers independently include mixed pulps of a wood pulp and a refined pulp with an &#x3b1;-cellulose content of 88 % by weight or more. The weight ratio of the layers and the beating degree of the mixed pulps are set in the specific ranges.

Water-dispersible sheet

A refillable container including an outer container (), a lid member (), an inner container (), and a pump (). 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 () of the pump, which is arranged below the lid member, is inserted from a suction port (), which is formed in an upper surface of the inner container, into the inner container.
