FIELD: construction.SUBSTANCE: system of liquid delivery comprises at least one foam material with gradient porosity. The foam material is filled with liquid and is arranged as capable of passive and permanent liquid release regardless of gravitation during contact between an application surface with other surface. At the same time the foam material with gradient porosity is characterised by extent of compression that varies along its length within the limits from approximately 0 to approximately 20.EFFECT: gradual serial delivery of liquid compositions that does not depend on gravitation and allowing for variations depending on a task set.1 cl, 5 dwg |
