Methods, Devices and Systems for Refilling a Liquid Dispenser

摘要

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.

主权项

1. A liquid refill system for use with a fragrance composition, said liquid refill system (10) comprising:
a) a child device having a liquid reservoir having a volume (VCR) and an air outlet valve said device having a first portion having a dispensing mechanism and a second portion having a child component of a refill mechanism comprising a child liquid inlet and a child one way liquid inlet refill valve associated therewith; b) a parent device having a liquid reservoir containing a liquid and an optional air inlet valve said device having a first portion having a parent component of a refill mechanism and a liquid outlet having a one way liquid valve associated therewith, said parent device having a pump having a pump volume (VPP), in liquid communication with the parent liquid reservoir via a one way liquid inlet valve and in liquid communication with said liquid outlet and optionally having a liquid return valve, wherein the ratio of the volume of the parent pump to the volume of the child reservoir is 12:1 or less.
