Abstract
The specification discloses a disposable packet containing a substance to be released upon subjection of the packet to water. The pouch includes a water-soluble paper envelope with the substance sealed therein. The interior surfaces of the envelope are coated with adhesive in a discontinuous or disconnected pattern, so that the adhesive does not significantly impede dissolution of the envelope. The adhesive is activated in selected areas to seal the envelope.
