The illustrations really aren't that close... I am surprised CM won this claim
The name is different
the colors scheme is different
The character is different
the wording is different
The color of the beverage is different

To be honest I have seen way worse rip offs than this... 

PS - not defending the Admiral brand here, it looks like corporate  laziness which is par for most companies marketing strategy :'Copy what the other guys do'

Think how much money the Admiral brand has pissed away on bottling, labeling, advertising etc., just because some owner(s) knew better than the designers and marketers around them.
