Abstract: Apparatus comprising means for blow molding a preform having a body which is longitudinally partitioned by a bulkhead having the size, shape, and orientation required in a finished, precisely partitioned bulbous-shape container to convert the preform into such a finished bulbous-shape container while constraining the bulkhead from changing size, shape, or orientation during the blow molding operation. An integrated injection-blow molding embodiment is disclosed as well as discrete injection molding and blow molding apparatuses.

Abstract: A longitudinally partitioned bulbous-shape, top-opening container of unitary construction is provided which comprises a precisely shaped, sized, and oriented integral bulkhead. Such containers may be made by the method of providing a thermoplastic preform which is longitudinally partitioned by an integral bulkhead of the size, shape, and orientation desired in the finished container, and then blow molding the outer wall of the preform to the bulbous-shape of the finished container while constraining or confining the bulkhead from changing size, shape, or orientation.

Abstract: A porous article releasably containing a dry, activated bleaching composition suitable for use in an automatic dryer.
