You want to create a custom post type, but you don't want to be able to display those posts on the front end (either individually, via single.php, nor together in an archive using archive.php or index.php)?
If that's the case you can prevent displaying single posts or archives of that post type by editing the options for the post type (edit the post type at Toolset > Post types) and unchecking "has_archive" and "publicly_queryable", and checking "exclude_from_search".
