Abstract
A detergent-containing water-insoluble closed bag is so constructed as to open and discharge its contents under mechanical action in a washing machine in use. The seams of the bag may be heat-sealed or cold pressure sealed such that at least one seam will burst open in use. The bag material may be porous with a pore size selected to minimize dusting of the detergent. The bag material may include a thermoplastic component to enable heat-sealing. The bag may contain conventional detergent compositions and/or other fabric treatment materials. These products give consumer benefits both by way of improved efficiency in the use of the detergent compositions and in greater convenience in use.
