ABSTRACT:
A unitary package for use in the washing and in the conditioning treatment of fabrics in a laundering operation. There is provided a packet in which a multi-layer plug-like laminate is contained in and is bonded within a cup-like water-insoluble and water-impermeable receptacle having an open top. The laminate presents an exposed upper surface to the wash water in the tub of a washing machine. Only after the materials (for example, detergents) in the top layer of the laminate have dissolved and dispersed does the washing water reach to solublize the second layer containing the fabric conditioner (for example, a fabric softener). Thus, the article of the invention ensures the simple and highly reliable manner time-spaced sequential incorporation of two different functional agents into a fabric washing system, even though the agents are added simultaneously.
