| abstract |
A solid chemical concentrate system comprising at least two cooperating molded parts. The first molded part is a bar which has been bent inward and has an interior opening. The second molded part is an insert which is introduced into the interior opening of said bar and interlocks with the latter. The solid chemical concentrate constitutes chemical systems comprising active constituents which may be identical, different but compatible, or functionally and chemically incompatible, combined within a matrix to form at least one substantially continuous surface. The system can also comprise a thin polymeric covering layer, soluble or dispersible in water. |
