Abstract: A flask, particularly for carrying alcoholic beverages, comprises a tubular body portion, having a seamless continuous internal surface, with respective inner end members fitted in the body portion to close the ends thereof and respective outer end members secured by soldering to the body portion at the ends thereof to define respective chambers between the inner and outer end members. The solder of the joints is out of contact with the interior of the flask, and any excess solder is received in the chamber, so that in use, liquid in the flask cannot become contaminated by contact with solder. A filling and pouring spout is secured to the inner and outer end members at one end of the flask.
