Abstract
The invention relates to an imposed means of ensuring that the sealing edge(s) of a flat, for instance rectangular, detergent-containing sachets is (are) kept closed. The sealing edge is of the type which is sealed with such a glue that it opens in the water of the washing machine at a temperature above room temperature. The improved means consists in that said sealing edges of the sachets may be bent as they are packaged in a box, as a result of which premature opening of the sachets is prevented during transport or after they have been introduced into the washing machine.
