You can try:
    <div tal:repeat...>
       <tal:div tal:define="
         myTypeObject	mytype/getObject;
	 parent		myTypeObject/aq_parent;
	 ">
	 ...
I am not sure that it will work.

  The "aq_parent" may return the wrong object.

  If it does, you need an internal method "getContainer"
  with the definition:

       def getContainer(obj): return obj.aq_inner.aq_parent
