Abstract

A new pouch for laundry products and the combination of pouch and laundry product. The pouch includes a tearing notch or a length of weakness, which may comprise a tear tape, permitting manual opening of the pouch prior to tossing the pouch into the washing machine. By tearing open the pouch it is possible to direct liquid or gelled detergent onto clothes for pretreating stains. The remainder of the product, in a second chamber, e.g. liquid, gel or solid, eg, a powder, is retained in the pouch until release during wash. In this respect, it is preferred that at least part of the pouch is a water soluble film to promote release of product during washing in the washing machine and to minimize residue left from the pouch at the conclusion of the wash. The pouch of the invention preferably comprises at least two chambers, one of the chambers being openable by manual tearing along a tearing notch or a line of weakness. In accordance with another embodiment of the invention, a pouch with one or more chambers is provided which narrows to a nozzle for dispensing of product.
