A hollow plastic product with a substantially tubular section, two open ends and a thread at the outside of one end of the product is removed from a core mold part by closing the threaded end of the molded product and injecting compressed air into the molded product to loosen the molded product from the core mold part. The threaded end of the product is closed by attaching a closure having a matching thread onto the threaded end.
