Fluid bottle with refill bottle opener

1. A fluid reservoir ( 50 , 70 , 80 ) capable of being refilled by a refill bottle ( 100 ) containing refill fluid, the refill bottle including an outlet passage ( 106 ) closed by a fluid seal ( 104 ), the fluid reservoir comprising:

an inlet passage ( 44 , 52 , 60 , 74 , 84 );

a support structure for holding the refill bottle ( 100 ) within the inlet passage in an orientation to encourage fluid in the refill bottle to flow into the inlet passage of the fluid reservoir, the support structure having a centrally disposed first opening in a bottom thereof; and

a piercing structure configured to surround the first opening, the piercing structure having a continuous first end in contact with the bottom of the support structure and a continuous distal end, portions of the distal end formed into a thin edge to pierce a seal of the refill bottle.

2. The device as defined in claim 1 wherein the first means is integrally formed as part of the inlet passage of the reservoir.

3. The device as defined in claim 1 wherein the support structure is configured to support refill bottle in an orientation that is neither vertical nor horizontal.

4. The device as defined in claim 1 wherein the support structure includes a housing having a central first axis which is configured at a non-zero vertical or horizontal angle relative to the inlet.

5. A fluid reservoir ( 44 , 52 , 60 , 84 ) capable of being refilled by a refill bottle ( 100 ) containing refill fluid, the refill bottle including an outlet passage ( 106 ) closed by a fluid seal ( 104 ), the fluid reservoir comprising:

a housing ( 202 ) having a bottom with an opening therein defining an inlet passage into the reservoir, a peripheral wall defining an open mouth for receiving the fluid bottle, and an inlet passage ( 44 , 52 , 60 , 74 , 84 ), the housing configured to receive the refill bottle thereon;

a plurality of spaced ribs configured to pierce the liquid seal as the refill bottle is placed upon the housing, each rib including a first and a second end and a body, each rib spanning the fluid inlet and spaced apart from one another, such spacing not blocking flow of fluid from the refill bottle, each of the first ends joined together at a common location apart from edges of the inlet passage, at least one piecing formation located proximate the common location.

6. The device as defined in claim 5 wherein the at least one piercing formation terminates below an outer end of the wall of the housing.

7. The device as defined in claim 1 including a plurality of piercing elements generally positioned about the opening in the bottom.

8. The device as defined in claim 5 wherein the inlet passage of the reservoir and the housing are configured to present the bottom at an angle that is not horizontal.

9. The device as defined in claim 5 wherein an axis through the inlet passage of the reservoir is generally vertical and wherein a center axis of the housing is angled relative to the axis of the inlet passage.

10. The device as defined in claim 1 wherein the piercing structure includes a tapered wall extending between the first and second ends.

11. The device as defined in claim 1 wherein adjacent portions of the tapered wall, not including the thin edge to pierce the seal, are recessed below the thin edge forming a valley between adjacent thin edges.

12. The device as defined in claim 5 wherein the common location at which the spaced ribs connect includes a second opening for fluid in the refill bottle to flow into the reservoir.

13. The device as defined in claim 1 wherein the first end of the piercing, where it connects to the bottom, is spaced apart by first spacing from a side wall of the inlet passage and wherein the bottom, with this first spacing, includes at least one additional flow opening.

14. A fluid reservoir ( 44 , 52 , 60 , 84 ) capable of being refilled by a refill bottle ( 100 ) containing refill fluid, the refill bottle including an outlet passage ( 106 ) closed by a fluid seal ( 104 ), the fluid reservoir comprising:

a housing ( 202 ) having a bottom with an opening therein defining an inlet passage into the reservoir, a peripheral wall defining an open mouth for receiving the fluid bottle, and an inlet passage ( 44 , 52 , 60 , 74 , 84 ), the housing configured to receive the refill bottle on the mouth;

the mouth oriented at an angle to the housing and configured to be installed to a mounting structure so that an axis through the mouth is at an angle that is between vertical and horizontal to facilitate receipt of the refill bottle.
