bicycle handle bar bags
What you describe I believe is an old Cannondale handle bar bag. I do not know if any body makes that particular design anymore. But rest assured there is a wide variety of handlebar bags on the market to meet every budget and every need. The following links are to a super nice one that I wish I could buy(below) and to one I own that is pretty decent (above). Just search for bicycle handle bar bags.
