Abstract
Disclosed herein is a device for draining a screw-on fluid filter which comprises a hollow body member movably engaged with a puncturing member. The hollow body member is dimensioned and arranged to at least partially engage a threaded attachment portion of the screw-on fluid filter. The puncturing member comprises a shaft having a puncture end movable within a conduit formed within the hollow body member wherein the puncturing member may be engaged with an inner side of a fluid filter to produce a puncture hole from inside out of the fluid filter, to produce a puncture hole from which fluid in the fluid filter may drain. A method of using the device is also disclosed.

A device for draining a screw-on fluid filter comprising:
- a hollow body member threadedly engaged with a puncturing member:
- the hollow body member comprising:
- a plurality of sides radially disposed about a central axis, the plurality of sides each having an outer surface separated from an inner surface by a thickness,
- wherein the outer surface of the plurality of sides defines a body member outer side and wherein the inner surface of the plurality of sides defines an internal conduit extending longitudinally along the central axis between a body member first end and a body member second end;
- the body member first end comprising outer threads disposed into at least a portion of the body member outer side, the outer threads being coaxially arranged about the central axis, wherein the outer threads are dimensioned and arranged to at least partially engage a threaded attachment portion of the screw-on fluid filter;
- and
- wherein at least a portion of the internal conduit comprises inner threads disposed into at least a portion of the inner surface,
- the puncturing member comprising:
- a shaft having a puncture end separated from a turning end,
- wherein at least a portion of the shaft is threaded,
- wherein at least a portion of the shaft is dimensioned such that the puncturing member threadedly engages the inner threads of the internal conduit such that rotating the puncturing member relative to the body member in a first rotational direction causes the puncture end to move away from the body member, and rotating the puncturing member relative to the body member in a second rotational direction causes the puncture end to move toward the body member.
A device for draining a screw-on fluid filter comprising:
- a hollow body member slidingly engagable with a puncturing member:
- the hollow body member comprising:
- a plurality of sides radially disposed about a central axis, the plurality of sides each having an outer surface separated from an inner surface by a thickness,
- wherein the outer surface of the plurality of sides defines a body member outer side and wherein the inner surface of the plurality of sides defines an internal conduit extending longitudinally along the central axis between a body member first end and a body member second end;
- the body member first end comprising outer threads disposed into at least a portion of the body member outer side, the threads being coaxially arranged about the central axis, wherein the threads are dimensioned and arranged to at least partially engage a threaded attachment portion of the screw-on fluid filter;
- the puncturing member comprising:
- a shaft having a puncture end separated from a striking end,
- wherein at least a portion of the shaft is dimensioned such that the puncturing member slidingly engages the internal conduit, and wherein the puncture end comprises at least one tapered end.
