Not sure what you mean by "container" here. A web viewer can be used to show a website or the system's default web viewer can be pointed at a specified URL from the database.
Much depends on the basic design of your database, but if each Part is a record--such as rows in a portal or rows of records in a list view, another field in the same record can store the URL associated with that part (or the ID of a related record that stores the URL so that multiple parts can refer to the same web site if that is needed.)
Button Setup can be used to set up a field (with the part number in it) as a button. This button can perform a script that uses Set Web Viewer and this associated URL field (or related record) to bring up the web site for that part.
