Sourcing of European Manufacturers - Thermos/Vacuum Flasks

We are looking to work with European manufacturers of vacuum flasks. Most production seems to happen in the east. We would like research to be done and a spreadsheet put together of potential companies that we can reach out to. They must be manufacturers not wholesalers. An example of the kind of product we are looking for is attached. Essentially a 0.5l stainless steel flask. Turkey manufacturers would also be acceptable.
