Patent NZ-595041-A (NZ)
Title: Refill liquid container
Inventor: FARRAR PETER ANTONY
IPC: A45D34/02
Filed: 2010-02-17
Abstract: 595041 A container system for liquids, including a parent container 110 and a child container 120, in which the parent container 110 provides a first cavity 113 for confining a liquid, and is configured to couple detachably to the child container 120 for refilling the child container 120 through a supply opening 111 in the parent container 110, and the child container 120 provides a second cavity 126 for confining a liquid, and comprises a dispensing mechanism 125 for dispensing liquid from the second cavity 126, and a fluid transfer assembly 123a for controlling liquid flow into the child container 120 through a refill opening. The fluid transfer assembly 123a forms a channel between the first cavity 113 and the second cavity 126 to allow liquid flow when the parent container 110 is coupled to the child container 120. The container system includes a movable part which, in one direction of travel, urges liquid from the parent container 110 to the child container 120. This movement is brought about as a consequence of the coupling of the child container 120 to the parent container 110 and is such as to cause an amount of liquid to pass from the first cavity 113 into the second cavity 126, sufficient to refill the child container 120 for further use, as soon as it is connected to the parent container 110. The system further includes a securing mechanism 130 for the detachable coupling of the child container 120 to the parent 110, so that, when they are coupled, the unit can be used in a combined configuration, drawing liquid from the parent container 110.
