A vented liquid containment device has a cup member located within the structure of a threaded cap so that a filter material can be placed within the cup member to prevent liquids from being splashed in an upward direction into contact with a vent that is formed within an inside portion of the cap.
A vented liquid containment device has a cup member located within the structure of a threaded cap so that a filter material can be placed within the cup member to prevent liquids from being splashed in an upward direction into contact with a vent that is formed within an inside portion of the cap. When used in conjunction with a marine vessel, rough water can cause oil within an oil reservoir to splash upwardly and come into contact with the vent opening which is intended to allow air and other gases to pass back and forth between the cavity of the reservoir and the atmosphere. The presence of the filter material prevents the liquids from being splashed into direct contact with the vent openings which could otherwise allow oil to spill outwardly onto surfaces of the reservoir and nearby components.

I claim: 1. A vented liquid containment device, comprising: a cap having a top portion and a generally cylindrical side portion; a thread structure formed on an inner surface of said generally cylindrical side portion; a vent formed within a preselected portion of said cap; a cup member shaped to be received within an inner portion of said cap; a flange extending in a radially outward direction from said cup member beyond a radially innermost portion of said thread structure and shaped to be received within said cap at a position proximate an inner surface of said top portion, said flange being retained in position relative to said cap by said thread structure; a fluid passage formed through a surface of said cup member, said fluid passage being disposed in fluid communication with said vent, said vent comprising a slot formed in said inner surface of said generally cylindrical side portion and said inner surface of said top portion; and filter material disposed within an internal cavity of said cup member. 2. The device of claim 1, wherein: said cup member comprises a tapered side surface, whereby a first end of said cup member has a larger diameter than a second end of said cup member. 3. The device of claim 2, wherein: said first end is disposed in contact with said inner surface of said top portion. 4. The device of claim 3, wherein: said second end extends away from said cap. 5. The device of claim 1, further comprising: a reservoir having a neck, said neck being threaded to receive said thread structure in attaching relation between said neck and said cap. 6. The device of claim 5, wherein: said reservoir is an oil reservoir. 7. The device of claim 1, further comprising: a seal disposed within said cap, said flange being disposed between said top portion of said cap and said seal. 8. The device of claim 1, wherein: said filter material comprises a polishing pad. 9. A vented liquid containment device, comprising: a cap having a top portion and a generally cylindrical side portion; a thread structure formed on an inner surface of said generally cylindrical side portion; a vent formed within a preselected portion of said cap; a cup member shaped to be received within an inner portion of said cap; a flange extending in a radially outward direction from said cup member and shaped to be received within said cap at a position proximate an inner surface of said top portion, said flange being retained in position within said cap by a radially innermost portion of said thread structure; a fluid passage formed through a surface of said cup member, said fluid passage being disposed in fluid communication with said vent; filter material disposed within an internal cavity of said cup member; and a seal disposed within said cap, said flange being disposed between said top portion of said cap and said seal, said vent comprising a slot formed in said inner surface of said generally cylindrical side portion and said inner surface of said top portion. 10. The device of claim 9, wherein: said cup member comprises a tapered side surface, whereby a first end of said cup member has a larger diameter than a second end of said cup member. 11. The device of claim 10, wherein: said first end is disposed in contact with said inner surface of said top portion. 12. The device of claim 11, wherein: said second end extends away from said cap. 13. The device of claim 12, further comprising: a reservoir having a neck, said neck being threaded to receive said thread structure in attaching relation between said neck and said cap. 14. The device of claim 13, wherein: said reservoir is an oil reservoir. 15. The device of claim 14, wherein: said filter material is an expanded foam. 16. A vented liquid containment device, comprising: a cap having a top portion and a generally cylindrical side portion; a thread structure formed on an inner surface of said generally cylindrical side portion; a vent formed within a preselected portion of said cap; a cup member shaped to be received within an inner portion of said cap; a flange extending in a radially outward direction from said cup member and shaped to be received within said cap at a position proximate an inner surface of said top portion, said flange being retained in position within said cap by a radially innermost portion of said thread structure; a fluid passage formed through a surface of said cup member, said fluid passage being disposed in fluid communication with said vent, said vent comprising a slot formed through said thread structure in said inner surface of said generally cylindrical side portion and said inner surface of said top portion; filter material disposed within an internal cavity of said cup member; and a seal disposed within said cap, said flange being disposed between said top portion of said cap and said seal; and a reservoir having a neck, said neck being threaded to receive said thread structure in attaching relation between said neck and said cap. 17. The device of claim 16, wherein: said vent comprises a slot formed in said inner surface of said generally cylindrical side portion and said inner surface of said top portion, said cup member comprising a tapered side surface, whereby a first end of said cup member has a larger diameter than a second end of said cup member, said first end being disposed in contact with said inner surface of said top portion, said second end extending away from said cap. 18. The device of claim 17, wherein: said reservoir is an oil reservoir.
