Abstract

Embodiments of the present invention provide water bottle cap assemblies suitable for attachment to an endoscopic device and a water source. The water bottle cap assembly can include a plurality of ports and an engageable member to sealingly engage the cap with a water source. The assembly also includes a plurality of tubular members, each tubular member coupled to a respective port so as to be in fluid communication therewith. The assembly can include a cap having a grippable surface that is overmolded onto the cap. The cap can also have a soft inner seal on the interior surface, and the soft inner seal can be integrally formed with the overmolded grippable surface. The cap can have a top that is pressfit onto the main portion of the cap. The grippable surface material can be overmolded over the top of the cap.

First claim

What is claimed is:

1. A water bottle cap comprising a substrate, a top, a collar, and a sealing member, wherein the substrate comprises:
a plurality of flanges connected at an upper region of the substrate to form a circular upper edge of the substrate, each flange having a free end spaced apart from the free end of other flanges at a lower region of the substrate,
an outer surface, and
an inner surface,
wherein the sealing member is configured to absorb slack between the inner surface and a water bottle connected to the inner surface,
wherein the free end of each flange has a plurality of thread portions on the outer surface of the substrate,
wherein the collar comprises a plurality of threads on an interior collar surface for mating with the plurality of thread portions of the free end of each flange,
wherein the collar is configured to be positioned onto the outer surface of the substrate and tighten the flanges to tighten the substrate onto a water bottle opening, and
wherein the top of the cap comprises a plurality of ports and the top is pressfit onto the substrate near the circular upper edge of the substrate.

2. The water bottle cap of claim 1 , wherein the collar is configured to twist in a first direction onto the outer surface of the substrate.

3. The water bottle cap of claim 2 , wherein the plurality of thread portions of the free end of each flange are angled and correspond to the threads on the interior surface of the collar.

4. The water bottle cap of claim 1 , wherein the collar is configured to be pressed onto the outer surface of the substrate.

5. The water bottle cap of claim 1 , wherein at least one of the ports comprises a hollow cylindrical boss and extends in a direction exterior to the top of the cap.

6. The water bottle cap of claim 1 , wherein the sealing member is pliable enough to prevent fluid from passing between the inner surface and a variety of water bottle openings.

7. The water bottle cap of claim 5 , wherein the hollow cylindrical boss is integrally formed with the top.

8. The water bottle cap of claim 5 , wherein the hollow cylindrical boss is pressfit into the opening.

9. The water bottle cap of claim 5 , wherein the hollow cylindrical boss is integrally formed with a base, such that the base is held in place and partially covered by the top.

10. The water bottle cap of claim 1 , wherein the sealing member covers the entire inner surface of the substrate.
