  • Patent number: 5064106
    Abstract: A package for dispensing premeasured quantities of a granular or powdered fluent material, having an elongate container with sloping shoulders and an open, upstanding neck surmounted by an overcap. The overcap has a topwall, a dispensing orifice, an outer skirt, and an inner skirt separate from or partially contiguous with the outer skirt. The inner skirt surrounds the container neck in an overlapping, laterally-spaced relationship. These define a preliminary measuring section above the container neck bounded by the topwall and the inner skirt, a main measuring section bounded by the sloping shoulders and the outer skirt, and an outlet passage located between the inner and outer skirts and communicating with the dispensing orifice.

  • Patent number: 5040783
    Abstract: A stacking device for forming stacks of articles of predetermined count, using a stacking wheel having a multiplicty of uniformly spaced peripheral slots. The slots are adapted to receive articles sequentially at a loading station and carry them to an unloading station having a plurality of stacking sites. The slots are divided into two or more sets, the slots in each set being equal to number to the predetermined count and adapted to deliver the articles therein to the unloading station with the leading edges of the articles at a predetermined radial offset from the axis of the stacking wheel. Each set of slots is associated with the stacking of articles at a specific stacking site and the slots of a set associated with one stacking site provide a different radial offset than those of a set associated with another stacking site. The stacking sites are arranged, in the downstream direction, in order of diminishing radial offset of their associated sets of slots.

  • Patent number: 5015245
    Abstract: Disposable sanitary articles comprise paper treated with polycationic latexes as wet-strength agents. The paper has sufficient wet strength that it can serve as the backsheet for absorbent articles, garments, and the like. Thus, KYMENE is reacted, for example, with acrylic acid and cross-linked with styrene/butadiene to provide a polycationic latex which is used to treat paper to enhance its wet strength. Diapers, sanitary napkins, pantiliners, and the like, prepared from the foregoing materials are disclosed.

  • Patent number: 5009804
    Abstract: Granular laundry detergent compositions are disclosed comprising two separate surfactant-containing components, optionally together with other dry mixed ingredients. The first component, preferably spray dried, contains a slowly-dissolving surfactant in combination with an organic and/or inorganic salt. The surfactant is preferably a long chain (C.sub.16+) alkyl sulfate or a long chain fatty acid salt. The second component comprises one or more surfactants of higher solubility rate and is preferably formed by agglomeration. Satisfactory release of the compositions from the dispensing compartment of an automatic washing machine can be maintained even when the compositions are of a concentrated high density type.

  • Patent number: 5000978
    Abstract: A process for making coated detergent granules by producing detergent granules and then uniformly distributing finely divided powder onto the surfaces of the detergent granules by means of an electrostatic charging and delivery system. The detergent granules are comprised of from about 10 to 20 weight % water so that the finely divided powder adheres to the moist detergent granules even after the electrostatic change dissipates.
