SELF-CLOSING VENTILATION INSERT (OPTIONS), APPLICATION OF VENTILATION INSERT (OPTIONS) AND METHOD FOR ITS MANUFACTURE

摘要

1. A self-closing ventilation insert (1) for textiles, shoes or objects, containing at least! one core element (9) with a first breathable layer (2), with an absorber (3) located on the first breathable layer (2), swelling upon contact with water to form an absorption layer, with a second breathable layer (4), and coatings ( 5, 6) on top of the first and second breathable layers (2, 4) and one layer (7) of the base on the coatings (5, 6), characterized in that the coatings (5, 6) and / or layers (7) of the base, if necessary when compressed in separate sections of breathable layers (2, 4) form the structure of chambers (8), limiting which maximize the spread of the absorber and the seal of the absorber during the swelling process, which closes the ventilation insert. ! 2. The ventilation insert according to claim 1, characterized in that the core element (9) and, if necessary, coatings contain fixtures (10) for fixing, which provide positioning of the element in the mold for injection molding. ! 3. The ventilation insert according to claim 1 or 2, characterized in that the core element is made of breathable layers (2, 4), the absorption layer (3), and, if necessary, the coatings (5, 6) have passage openings (11), through which in the manufacture of the ventilation insert passes fluid material for the base layer. ! 4. The ventilation insert according to claim 1, characterized in that the core element (9) of the ventilation insert is made integrally of breathable layers (2, 4) and an absorption layer (3), preferably in the form of a fleece equipped with an absorber, and preferably a core element (9 ) and coatings (5, 6) form
