Document.Container (Word)

Returns the object that represents the container application for the specified document.

The Container property provides access to the specified document's container application if the document is embedded in another application as an OLE object. This property also provides a pathway into the object model of the container application if a Word document is opened as an ActiveX document — for example, when a Word document is opened in Microsoft Office Binder or Internet Explorer.
