Abstract
The present disclosure relates to a liquid refilling system (10) including a parent device (201) and a child or portable travel sized device (101) that can be releasably coupled to the parent device (201) to transfer liquid from the parent to the child device. The parent device (210) is provided with a pump (207) in liquid communication with a parent reservoir (203) containing the liquid. The pump of the parent device has a volume which is preferably substantially equal to the volume (Vcr) of the child reservoir thereby enabling a minimal number of single actuations of the parent pump (207) to completely fill the child reservoir (103) if desired upon coupling thereof.
