How about something like this:

class Outer
   class Inner
     def initialize(&block)
       @cleaner = block
     end

     def close
       @cleaner.call self
     end
   end

   def create_inner
     inner = Inner.new { |_inner|
       remove_inner(_inner)
     }
     ...
   end

   private
   #######
   def remove_inner
     ...
   end
end
