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.

1. A free-standing dispenser (220; 320; 420; 520) for liquids, the dispenser comprising: a bowl- or tray-shaped rigid container (221) with an open face, the container having a refill opening (222), which is kept closed by a valve unless the dispenser is connected to a supply container, and a dispens
1. A free-standing dispenser (220; 320; 420; 520) for liquids, the dispenser comprising: a bowl- or tray-shaped rigid container (221) with an open face, the container 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 being located with a spacing from each other;wherein the open face of the bowl is covered by a deformable resilient membrane (227) to form a closed dispense cavity (226) adjacent to the refill opening, the volume of this cavity being reduced as the membrane is deformed inwardly so as to empty the cavity, the refill and dispense openings being such that if the dispenser is applied to the supply container by way of the refill opening, with the cavity initially empty, when the membrane is subsequently allowed to spring back to its rest shape it draws liquid from the supply container into the cavity;wherein the resilience of the membrane, when deformed, exerts sufficient negative pressure to suck liquid in from the supply container when liquid within the supply container is unpressurized;wherein the dispenser is configured to be readily detached from the supply container for use;wherein the dispenser is configured to automatically commence drawing liquid from the supply container into the cavity to refill or recharge the cavity as soon as the dispenser is attached to the supply container. 2. A dispenser according to claim 1, further including a pump (225) for dispensing liquid from the dispense opening (224), the cavity becoming mainly or completely evacuated as the pump is operated. 3. A dispenser according to claim 1, in which the rigid container is generally round in outline and the refill and dispense openings are located approximately at opposite ends of a diameter. 4. A dispenser according to claim 1, in which a lip of the bowl, defining the open face, has a groove and the membrane is retained in this groove by a sealing ring (228). 5. A dispenser according to claim 1, in which the membrane is integral with the bowl. 6. A dispenser according to claim 1, in which the dispenser (320) is generally spherical, the rigid container (321) being approximately a hemisphere and the membrane (327) approximately forming the other half of the sphere. 7. A dispenser according to claim 6, in which the dispense opening takes the form of a manual valve (325). 8. A dispenser according to claim 7, in which the manual valve (325) is located on the membrane (327). 9. A dispenser according to claim 1, and including an auxiliary restoring means (340) assisting the membrane to return to the full configuration. 10. A dispenser according to claim 1 and having the form of a flat-sided bottle (420), one or each flat side being constituted by a membrane (427). 11. A container system for liquids, including a parent container (110; 310) and a free-standing child container (220; 320), in which: the parent container (110) provides a storage cavity (113) for confining a liquid;the child container (220) is configured to be readily detached from the parent container (110) for use;the child container (220) is further configured to be recoupled to the parent container (110) and to automatically commence drawing liquid from the parent container (110) through a supply opening (111) in the parent container (110) to refill or recharge the child container (220) as soon as the child container (220) is recoupled to the parent container (110);the child container (220) is a dispenser having a refill opening (222), which is kept closed by a valve unless the child container (220) is connected to the parent container (110), and a dispense opening (224), these openings being located with a spacing from each other; andan open face of the child container (220) is covered by a deformable resilient membrane (227) to form a dispense cavity (226) adjacent to the refill opening, the volume of the dispense cavity being reduced as the membrane is deformed inwardly so as to empty the dispense cavity, the refill and dispense openings being such that if the child container is applied to the parent container by way of the refill opening, with the dispense cavity initially empty, when the membrane is subsequently allowed to spring back to its rest shape it draws liquid from the parent into the dispense cavity;wherein the resilience of the membrane, when deformed, exerts sufficient negative pressure to suck liquid in from the supply container when liquid within the supply container is unpressurized. 12. A container system (100) according to claim 11, wherein the membrane urges liquid from the parent container (110; 310) to the child container (220; 320) when the child container (220) is coupled to the parent container (110), so as to cause an amount of liquid to pass from the storage cavity (113) into the dispense cavity (226), ensuring that the child container (220) is filled when connected to the parent container (110). 13. A container system according to claim 11, wherein the child is attached to the parent by a magnetic connection. 14. A container system for liquids, including a parent container (510) and a free-standing child container (520), in which: the parent container (510) provides a storage cavity for confining a liquid, and is configured to refill the child container (520) through a supply opening in the parent container (510);the child container (520) comprises a refill opening (522), which is kept closed by a valve unless the child container is connected to the parent container, and a dispense opening (524), these openings being located with a spacing from each other; and a dispense cavity (526) adjacent to the refill opening, whose volume is reduced as liquid is dispensed, the refill and dispense openings being such that if the child container is applied to a suitable parent container by way of the refill opening, with the dispense cavity initially empty, a resilient component draws liquid from the parent into the dispense cavity;the resilience of the membrane, when deformed, exerts sufficient negative pressure to suck liquid in from the supply container when liquid within the supply container is unpressurized;the connection between parent and child containers is magnetic, so that the child container is readily detachable from the parent container; andthe child container is configured to reattach to the parent container, and once attached, to automatically commence drawing liquid from the parent container into the dispense cavity to refill or recharge the dispense cavity as soon as the child container is attached to the parent container. 15. A container system according to claim 14, wherein the child container (520) does not contain a ferromagnetic part.
