Many homes have this seemingly simple device. The thermos, or Dewar vessel, was once invented for the chemical industry, but today it is used in all spheres of life, from the same chemistry and physics to household needs. So what if your faithful assistant is out of order?
Instructions
Step 1
Determine the cause of the breakdown. If it's all about the vacuum tube, then home repair is almost impossible. To do this, you need special equipment that allows you to work with vacuum. The purchase of which will cost more than the thermos itself. In this case, it is easier to take the thermos to a repair shop or, indeed, buy a new one.
Step 2
If the bottom of the thermos is broken or rusted, it is not difficult to repair it. Cut a circle with a diameter of the bottom of a thermos from a regular tin can. Place a corrugated cardboard circle (you can cut it out of a box from household appliances) and foil (cut it out of a tea bag) as a shock absorber between the flask and the cut out circle. Thus, you get good thermal insulation from the bottom.
Step 3
Secure it all with small nails. Make a cross from the rails and nail it to the body of the thermos. You can also make a wooden circle if you can cut it out (then the thermos will have a more aesthetic appearance).
Step 4
If the problem lies in the lid of the thermos, more precisely, in the stopper, it can also be solved. Clean the old cork material and wrap it with a thick synthetic cloth in several layers. On top of it, glue or tie polyethylene or a rubber layer (you can take the material from ordinary rubber gloves).
Step 5
Wrap all this at the base with a strong bundle and fit the old plug in place. This design is temporary and not very aesthetic, but functional and will help keep you warm.
Step 6
If the outer shell of the thermos is crumpled, and the tube itself is not damaged, take the thermos to the nearest auto repair shop, there they will certainly help to deal with the dents. However, you can try to straighten the dent yourself with a hammer, but you risk damaging the internal structure (see step 1).
