An improved lining for thermos, essentially characterized by the fact that it consists of two pieces, one of them a frame made of waterproof elastic material that forms a ring that fits against the outside of the neck of the thermos protecting it and sealing against any slippage of the liquid towards the interior of the sheath, this fence carrying a raised edge forming a pouring lip that only affects a sector of it.
