PROBLEM TO BE SOLVED: To provide a refilling bag facilitating holding an inlet on the opening part of a bottle, preventing an inserted inlet from being blocked, and capable of increasing a flow quantity of liquid to extract.SOLUTION: Notches 11 and 12 are provided on both sides of an inlet 10, so it is easy to hold the inlet in a state of inserting into the opening part of a bottle, and to perform a refilling operation. Since there are two pairs of linear recesses 20 formed facing each other on the front and back surfaces, from a section close to an inlet seal part in the vicinity of a base part of the inlet 10 to a bag body, a flow quantity and a flow velocity of liquid going from both the notches to the inlet are suppressed, and a quantity of liquid invading into the inlet is suppressed when extracting content liquid in a state of inserting the inlet into the opening part of the bottle, consequently, the inlet can be prevented from being blocked. Furthermore, since no recess is provided on a section excluding the vicinity of the base part of the inlet, a sufficient extraction flow channel is secured so as to enlarge a flow quantity and a flow velocity of liquid to extract. |
