Abstract

A refillable liquid product container system comprises a liquid product container (100) having a body and a neck extending outwardly from the body, wherein said neck or an optional dispensing fitment arranged in said neck facilitates dispensing of a liquid product from the container. The system also includes a manually operable screw cap (1) that is to be removed by a user from the container (100) when a liquid product is to be dispensed from the container, and that is to be replaced to close the container. The screw cap has a top wall (2) and a downward depending circumferential skirt (3), and wherein the screw cap has a screw thread (11) that mates with a screw thread on said neck or on said optional dispensing fitment when present. A refilling station (110) allowing a user to refill the container (100) with a liquid product, said refilling station comprising a male filling element (30) through which said liquid product is supplied to the container.

Claims

1. A refillable liquid product container system comprising:

a liquid product container comprising;

a body and a neck extending outwardly from the body, wherein said neck or an optional dispensing fitment arranged in said neck facilitates dispensing of a liquid product from the container; and

a manually operable screw cap that is to be removed by a user from the container when a liquid product is to be dispensed from the container, and that is to be replaced to close the container;

wherein the screw cap has a top wall and a downward depending circumferential skirt, and wherein the screw cap has a screw thread that mates with a screw thread on said neck or on said optional dispensing fitment when present;

a refilling station allowing a user to refill the container with a liquid product, said refilling station comprising a male filling element through which said liquid product is supplied to the container;

wherein the screw cap is provided with a tubular portion, said tubular portion forming a bore for the male filling element of the refilling station, said bore having an insertion opening at the top wall for the male filling element;

wherein said tubular portion forms in said bore a seat for a stopper at a distance from the insertion opening;

wherein the container further comprises a stopper that is arranged in the seat to close off the bore;

wherein the male filling element has a tubular portion which fits into the bore, and the male filling element is provided with a liquid product passage which extends through its tubular portion to one or more ports for dispensing the liquid product into the container;

wherein the male filling element has a head which is adapted to couple with the stopper, so that upon introduction of the male filling element into the bore, the head couples with the stopper when in its seat and upon further introduction of the male filling element into the bore, presses the stopper off its seat so that the one or more dispensing ports come in communication with the interior of the container;

and so that upon withdrawal of the male filling element from the bore, the male filling element draws the stopper in its seat, and upon further withdrawal uncouples from the stopper.

2. System according to claim 1, wherein the tubular portion of the screw cap extends downwardly from the top wall of said cap.

3. System according to claim 1, wherein the container is a unitary blow-molded hand-held plastic container.

4. System according to claim 1, wherein the body of the container is a collapsible pouch, the pouch being provided with a spout forming the neck of the container.

5. System according to claim 1, wherein the screw cap is a dosing cap with an effective dosing volume.

6. Method of refilling a container in a system according to claim 1 comprising:

providing the container with the cap secured onto the neck of the container to be refilled;

bringing the container to the refilling station;

introducing the male filling element into the bore of the cap so as to couple the head of the male filling element to the stopper;

pressing the stopper of its seat;

filling the liquid into the container via the male filling element;

terminating the filling;

withdrawing the male filling element from the bore, thereby pulling the stopper into its seat; and

disconnecting the head from the stopper upon continued withdrawal of the male filling element.

7. System according to claim 5, wherein the effective dosing volume is at least 10 milliliters.
