I assume the second "line" of your drawing is skewed. I presume 
the foil extends out of the cap (where my arrows are pointing) to 
enable connections to be made?  That scheme ispretty much the 
one I used except I used folded plastic rather than silicone rubber. It 
still doesn't exclude air from the cap and oil would not only be 
difficult to get into a design like that but it will also do things to the 
rubber.  For exactly those reasons I have gone the MMC and/or 
commercial cap route.

Regards,
Malcolm
