Molded filter end cap and method of manufacture

1. A filter element, comprising:

a filter media having first and second filter ends;

a first end cap attached to the first filter end;

a second end cap attached to the second filter end, the second end cap formed from a molded material and including a handle structure unitarily molded therein, the handle structure including a flange with a void formed at least partially transversely therethrough, the void molded without a mold split such that no mold split parting line is formed on the second end cap; the molded material being molded directly to the filter element; and

wherein the second end cap includes a side wall progressing around the handle structure, and wherein the void opens toward diametrically opposed portions of the side wall, and wherein a portion of the void and the flange are disposed above a rim of the side wall.

2. A filter element, comprising:

a filter media having first and second filter ends;

a first end cap attached to the first filter end;

a second end cap attached to the second filter end, the second end cap formed from a molded material and including a handle structure unitarily molded therein, the handle structure including a flange with a void formed at least partially transversely therethrough, the void molded without a mold split such that no mold split parting line is formed on the second end cap; the molded material being molded directly to the filter element; and

wherein the second end cap is a closed end cap including a circumferential side wall and a solid floor extending radially inwardly from the circumferential side wall, the floor unitarily molded with a lower portion of the side wall such that the floor and side wall form a recess in the second end cap, the handle structure projecting from the floor.

3. The filter element of claim 2 , wherein the flange of the handle structure in the second end cap includes a bottom and opposing ends, the bottom and a portion of the opposing ends within the recess unitarily molded with the solid floor and the circumferential side wall, respectively, and the flange intersecting a central axis such that the flange of the handle structure divides the recess.

4. A filter element comprising:

a filter media having first and second filter ends;

a first end cap attached to the first filter end;

a second end cap attached to the second filter end, the second end cap formed from a molded material and including a handle structure unitarily molded therein, the handle structure including a flange with a void formed at least partially transversely therethrough, the void molded without a mold split such that no mold split parting line is formed on the second end cap;

wherein the filter media is embedded into a side wall above a floor in surrounding relation to the handle structure.

5. A filter element, comprising:

a filter media having first and second filter ends;

a first end cap attached to the first filter end;

a second end cap attached to the second filter end, the second end cap formed from polyurethane having a free rise surface and including a handle structure unitarily molded therein, the handle structure including a flange having a grommet molded therein, the grommet defining an aperture passing transversely through the flange.

6. The filter element of claim 5 , wherein the second end cap includes a circumferential side wall and a floor extending radially inwardly from the circumferential side wall, and wherein a central axis of the aperture is generally parallel to a top surface of the floor; and wherein the grommet includes an exposed grommet surface, the exposed grommet surface planar with an external surface of the flange adjacent the exposed grommet surface.

7. The filter element of claim 5 , wherein the grommet includes a groove extending circumferentially around an outer periphery, the groove permitting the grommet to interlock with the flange of the handle structure; and wherein the grommet is formed from an elastomeric material.

8. The filter element of claim 5 , wherein an upper portion of the flange and a portion of the aperture passing through the flange are each disposed above a rim in a sidewall of the second end cap; and wherein the aperture formed by the grommet is sized and dimensioned to receive one or more human fingers.

9. The filter element of claim 5 , wherein the second end cap includes at least one locating lug including a chamfered lower portion, the chamfered lower portion having a decreasing profile as the chamfered lowered portion progresses toward a bottom of the second end cap.

10. A filter element, comprising:

a filter media having first and second filter ends;

a first end cap attached to the first filter end;

a free rise molded second urethane end cap being formed around the second filter end and including a handle structure unitarily molded therein, the handle structure including a flange with a void formed at least partially transversely therethrough.

11. The filter element of claim 10 , wherein the void is molded without a mold split such that no mold split parting line is formed on the second end cap.

12. The filter element of claim 10 , wherein the void in the flange is surrounded by a grommet, the grommet being molded into the flange.

13. A filter element, comprising:

a filter media having first and second filter ends;

a first end cap attached to the first filter end;

a second end cap attached to the second filter end, the second end cap formed from a molded material and including a handle structure unitarily molded therein, the handle structure including a flange with a void formed at least partially transversely therethrough, the void molded without a mold split such that no mold split parting line is formed on the second end cap; the molded material being molded directly to the filter element; and

wherein the molded material has a free rise surface formed by an open molding technique.
