C-c C-u then M-x hide-subtree would close parent heading.. You can do

(defun close-parent-heading ()
  (outline-up-heading 1)

then bind it to a key.
If you want to hide parent headings until you reach certain condition, then 
have to write a more complicated function like so:

(defun fold-until-tagged-blah ()
  "Fold headings containing point upward until heading tagged :blah"
  (let (done)
    (while (not done)
      (cond ((member "blah" (org-get-tags-at nil t))
             (setq done t))
            ((not (org-up-heading-safe))
             (setq done t))))
