Abstract
Abstract A sachet of flexible sheet material containing a composition, for example, for treating fabrics in a washing machine, so shaped and dimensioned that when immersed in water in the absence of the treatment composition its thickness at at least one point is at least 1 cm . The thickness of the sachet thus remains at least 1 cm after delivery of its contents, so that passage of the sachet between the inner and outer drums of an automatic washing machine is prevented or substantially reduced.
