US Patent 9427063 Compact liquid container

The present invention relates to a container system for liquids such as spray fragrances. The system includes a parent container (110) and a child container (120). The parent container provides a first cavity (113) for confining a liquid, and couples detachably to the child container for refilling the child container through a supply opening (111) in the parent container, so that the child container can be used for instance as a travel pack in a handbag or hand luggage. Here the child container is a compact dispenser, comprising a bowl-shaped rigid container (221) having a refill opening (222), which is kept closed by a valve unless the dispenser is connected to a supply container, and a dispense opening (224). These openings are located with a spacing from each other, and a pump (225) dispenses liquid from the dispense opening (224). In this particularly simple construction, the opening of the bowl is covered by a deformable membrane (227) to form a closed dispense cavity (226), the cavity becoming mainly or completely evacuated as the dispensing means is operated. The membrane then relaxes again, filling the dispenser, when the dispenser is re-applied to the parent container.
