<p>A moisture-absorbing device comprises a tube (2) which is made of board coated with plastic and which in its longitudinal direction is devided into an upper chamber containing a moisture-absorbing agent and a lower chamber containing a liquid-collecting means (15) and communicating with the upper chamber via a liquid-permeable means (10, 11, 12). The tube (2) has at least one opening (5) on a level with the upper chamber. A netting element (6), which has at least one fine-mashed netting portion (7), is so attached to the inside of the tube (2) that the netting portion (7) is located in front of the opening (5). The liquid-collecting means consists of a liquid-tight container (15) connected to the liquid-permeable means (10, 11, 12).</p> |
