Abstract

One general aspect includes a cap for a the overflow reservoir bottle, including a lower cup having a syncline void, said syncline void having by a wall extending above and below at least one surface of the lower cup. The cap also includes an upper cup with an anticline projection nesting adjacent to the syncline void of the lower cup, and said upper cup affixed to the lower cup, with at least one vent to permit gas to traverse the overflow reservoir bottle.

First claim

What is claimed is:

1. A recovery cap for an overflow reservoir bottle, comprising:
a lower cup having a syncline void defined by an upper wall extending above a surface of the lower cup and an outer wall extending below a surface of the lower cup; and
an upper cup with an anticline projection nesting adjacent to the syncline void of the lower cup, the upper cup being affixed to the lower cup,
wherein a first distance defines a vent to permit gas to traverse the overflow reservoir bottle provided between a first horizontal wall of the upper wall and the upper cup and wherein a second distance is defined between a second horizontal wall of the upper wall and the upper cup, the first distance and the second distance being different.

2. The cap of claim 1 , wherein the upper cup is affixed to the lower cup by at least one of a plastic weld, an adhesive bond and a mechanical fastener.

3. The cap of claim 1 , wherein the anticline projection further includes a notch to increase a surface area of the anticline projection.

4. The cap of claim 1 , wherein a lower wall extending below a lower surface of the lower cup is at a first angle relative a perpendicular plane to said at least one surface of the lower cup.

5. The cap of claim 4 , wherein a first upper wall extending above a second face of the lower cup is at a second angle relative the perpendicular plane to said at least one surface of the lower cup.

6. The cap of claim 5 , wherein a second upper wall extending above the second face of the lower cup is at a third angle relative the perpendicular plane to said at least one surface of the lower cup.

7. The cap of claim 1 , wherein the lower cup has a thread pattern to attach the cap to the overflow reservoir bottle.

8. The cap of claim 1 , wherein the lower cup has a snap fastener to attach the cap to the overflow reservoir bottle.

9. A system to prevent loss of a liquid from an overflow reservoir bottle, comprising:
means for the overflow reservoir bottle to permit a gas to ingress and egress the overflow reservoir bottle via a cap with a lower cup having a syncline void defined by an upper wall and an outer wall, and an upper cup attached to the lower cup with an anticline projection nesting adjacent to the syncline void of the lower cup, a first distance defining a vent to permit gas to traverse the overflow reservoir bottle provided between a first horizontal wall of the upper wall and the upper cup and a second distance defined between a second horizontal wall of the upper wall and the upper cup, the first distance and the second distance being different.

10. The system of claim 9 , further including means for attaching the lower cup to the upper cup via at least one of a plastic welding and an adhesive bonding and a mechanical fastening.

11. The system of claim 9 , wherein the anticline projection further includes a notch to increase a surface area of the anticline projection.

12. The system of claim 9 , further including means for screwing the cap on to the overflow reservoir bottle.

13. The system of claim 9 , further including means for attaching the cap to the overflow reservoir bottle via a snap fastener.
