Liquid Refilling System and Devices

摘要

The disclosure relates to a liquid refilling system (10) having a parent device (201) and a child or portable travel device 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 has a pump (207), an actuator (217) and an actuator stroke limitation means (218) whereby the amount of liquid dispensed by the parent device (201) can be selected as a single use predetermined amount or as a child refill amount. The parent pump is in liquid communication with the parent liquid reservoir and the pump has a volume which is substantially equal to the volume of the child.

主权项

1. A liquid refill system for use with a fragrance composition, said liquid refill system comprising:
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; and a parent device having a liquid reservoir containing a liquid and preferably an 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 and an actuator releasably attached to said parent device, wherein said pump has 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 (Vpp) to the volume of the child liquid reservoir (Vcr) is 12:1 or less, preferably 1:1; and said actuator having an actuator stroke limitation means, whereby the maximum volume (Vpa) of liquid dispensed upon actuation of the actuator is predetermined and less than said pump volume (Vpp).
