A refill closure system to be used with bulk refill containers and targeted refill bottles in which the closure system includes a pour cap and a funnel, the funnel being sealed to the pour cap in a closed or non-use state and detached from the pour cap in a use state wherein the funnel may be inserted in a targeted refill bottle to facilitate filling of the targeted refill bottle from a bulk refill container.

First claim

What is claimed is:

1 . A refill system, comprising:
a refill container; a product in the container; a closure system attached to the refill container, comprising:
a pour cap, comprising:
a closure skirt;
a funnel skirt defining an interior space; and
a funnel plug positioned in the interior space;

a funnel, comprising:
a funnel wall;
a funnel attachment system; and
a chamfered edge at a small end of the funnel;
wherein the chamfered edge of the funnel engages an exterior surface of the funnel plug in a closed position.

2 . The refill system of claim 1 , wherein the funnel attachment system further comprises a threaded attachment system.

3 . The refill system of claim 1 , wherein the funnel attachment system further comprises a snap-fit attachment system.

4 . A closure system, comprising:
a pour cap, comprising:
a closure skirt;
a funnel skirt extending downwardly within the closure skirt and having a wall with an interior surface; and
one or more pour openings in the funnel skirt;
a funnel, comprising:
a funnel wall having an exterior surface configured and arranged to mate with said interior surface of said funnel skirt wall when received in assembled relation; and
a funnel attachment system;
wherein the funnel attachment system attaches the funnel to the pour cap in a closed position.

5 . The closure system of claim 4 , wherein the funnel attachment system further comprises:
a funnel skirt thread on said interior surface of the funnel skirt; and a funnel thread on the exterior surface of the funnel wall, wherein the funnel skirt thread and funnel thread are engaged in the closed position.

6 . The closure system of claim 4 , wherein the funnel attachment system further comprises:
an exterior thread on an exterior surface of the closure skirt; an attachment skirt extending off the funnel wall; and a funnel thread on an interior surface of the attachment skirt, wherein the funnel thread and exterior thread are engaged in the closed position.

7 . The closure system of claim 4 , wherein the funnel attachment system further comprises:
a retaining recess in an interior surface of the funnel skirt; and a retaining bead on an external surface of the funnel wall, wherein the retaining bead sits in the retaining recess in the closed position.

8 . The closure system of claim 7 , further comprising a stop skirt extending off an external surface of the funnel wall, wherein the stop skirt contacts the pour cap in a closed position and is not in contact with the pour cap in an open position.

9 . The closure system of claim 4 , further comprising at least one seal bead on an external surface of the funnel wall, wherein the at least one seal bead seals against an internal surface of the funnel skirt in the closed position.

10 . The closure system of claim 4 , further comprising a plug seal extending off of an exterior surface of the funnel skirt adjacent an interior surface of the closure skirt.

11 . The closure system of claim 4 , further comprising:
a bottom surface at an end of the funnel skirt wherein said one or more pour openings in said funnel skirt comprises one or more openings in said bottom surface.

12 . The closure system of claim 4 , further comprising:
a bottom surface at an end of the funnel skirt; and a funnel plug extending upwardly from the bottom surface into an interior space defined by the interior surface of the wall of the funnel skirt.

13 . The closure system of claim 4 , further comprising:
a bottom surface at an end of the funnel skirt; a funnel plug extending upwardly from the bottom surface into an interior space defined by the interior surface of the wall of the funnel skirt; and a chamfered edge at a small end of the funnel, wherein the chamfered edge seals to an exterior surface of the funnel plug in a closed position.

14 . A method of refilling a container, comprising:
providing a target container comprising a container opening; providing a refill product, the refill product comprising:
a refill container comprising a refill container opening;
a product stored in the refill container;
a pour cap attached to the refill container opening, the pour cap comprising a closure skirt, a funnel skirt extending downwardly within the closure skirt and having a wall with an interior surface, and one or more pour openings in the funnel skirt; and
a funnel attached to the pour cap, the funnel comprising a funnel wall having an exterior surface configured and arranged to mate with said interior surface of said funnel skirt wall when received in assembled relation, and a funnel attachment system, wherein the funnel attachment system attaches the funnel to the pour cap in a closed position;
removing the funnel from the pour cap; inserting the funnel in the target container opening; pouring the product from the refill container through the pour cap and into the funnel; removing the funnel from the target container opening; and reattaching the funnel to the pour cap.

15 . The method of claim 14 , further comprising:
removing a dispenser from the target container opening prior to inserting the funnel in the target container opening; and reattaching the dispenser to the target container opening after removing the funnel from the target container opening.

16 . The method of claim 14 , wherein removing the funnel from the pour cap further comprises unscrewing the funnel from the pour cap.

17 . The method of claim 14 , wherein the product stored in the refill container is a liquid soap.

18 . The method of claim 14 , wherein the product stored in the refill container is a lotion.

19 . The method of claim 14 , wherein the product stored in the refill container is a powder.

20 . A refill system, comprising:
a refill container; a product in the container; a closure system attached to the refill container, comprising:
a pour cap, comprising:
a closure skirt;
a funnel skirt defining an interior space; and
a funnel plug positioned in the interior space;
