FIELD: chemical industry; other industries; production of the filtering cartridges. ^ SUBSTANCE: the invention is intended for filtration. The filtering cartridge contains the body filled with filtering material and the bottom with the surrounding wall, and also the cover tightly sealing the body. The cover has the base and the formed on it along its periphery the strip-shaped lateral wall fixed on the inner side of the surrounding wall. The cover base in direction of the surrounding wall passes through the bent inside edge section in the lateral wall. At that the bent edge section and the strip-shaped lateral wall in the formed area are joined transforming into the sharp inside common wall section. The technical result of the invention is the decreased danger of the cutting destruction, provision of the additional tightening effort. ^ EFFECT: the invention ensures the decreased danger of the cutting destruction, provision of the additional tightening effort. ^ 15 cl, 4 dwg |
