Retaining cap

Abstract

A cap for a disposable oil filter. The cap is comprised of a locking ridge that is molded into the inside circumference of said cap. When firmly pressed over the seamed perimeter rim on the face end of the disposable oil filter, a locking ridge securely engages into the seam line, formed by the manufactures seaming process, thus locking cap on oil filter and forming a liquid tight seal on each side of locking ridge.

1 . A disposable retaining cap for a disposable oil filter, said filter having a threaded flow hole and a spin on type design, an inlet/outlet face end and a seamed perimeter rim with an inherent seam line, with said retaining cap comprising of a locking ridge and a flexible one piece design. Said retaining cap covers entire said inlet/outlet face end, said cap firmly snaps over said perimeter rim, said retaining caps' locking ridge engages into said inherent seam line, said retaining cap seals on each side of said locking ridge. 
   
   
       2 . A disposable retaining cap according to  claim 1 , molded of a flexible material, and oil resistant plastic. 
   
   
       3 . A disposable retaining cap according to  claim 1  that covers the entire inlet/outlet face end of a new disposable oil filter, thus forming a protective barrier. 
   
   
       4 . A disposable retaining cap according to  claim 1 , with the addition of a slightly oversized plug with ridges that is molded as one piece into the center of said retaining cap, said oversized plug inserts into said threaded flow hole of said disposable oil filter, and grabbed the threads, of said threaded flow hole, thus facilitating locking ridge and increasing the grip and integrity of said retaining cap, for a large diameter said disposable oil filter.
