Presents a liquid detergent refill pouch for easy refilling. This standing pouch with a spout has an inner disk inside the spout, preventing the detergent from coming out when the pouch is turned upside down. When the pouch spout is set at the bottle spout and the inner disk is pushed open, the contents are discharged without spilling. In addition, the unique structure allows the air in the bottle to be replaced by the contents, drastically reducing the time for refilling.
