  • Patent number: 5891008
    Abstract: An improved method is disclosed for forming a strata of overlapping sheets suitable for use in a pop-up dispensing system. The sheets are cut from ribbons which initially have edges essentially parallel to the longitudinal axis of the ribbon. At least one side edge of each ribbon is stretched to form a knee-like protrusion, with the opposing side edge being either, substantially parallel to the longitudinal axis of the ribbon, or also stretched to form one or more knee-like protrusions on the opposing edge. The ribbons are then aligned so that a knee-like protrusion on one edge aligns with either the essentially parallel edge of an adjacent ribbon or a knee-like protrusion on the side edge of an adjacent ribbon. After phasing, the ribbons are overlapped creating a series of predetermined areas of greatest overlap adjoining areas of least or no overlap, such that successive ribbons are bonded only by the interfacial interaction between each ribbon.

  • Patent number: 5656282
    Abstract: A pouch package, containing a volatile solution-impregnated patch, is made of a peelable barrier film. The pouch envelops an absorbent substrate saturated preferably with bug repellent fluid. A PSA (pressure sensitive adhesive) coated backing film is laminated to the absorbent substrate. The backing film has a connecting portion which is peelably sealed to the inside of the pouch. When the pouch is peeled open, the PSA coated backing film is exposed and placed against a target surface, such as a patch wearer's clothing. Finally, the side of the pouch facing the absorbent substrate is peeled off the backing film connecting portion to expose the absorbent substrate. A key to functionality of the pouch package is differential adhesion. First, the pouch barrier film must be peelable from itself, yet it must not adhere to the pressure sensitive adhesive on the backing film. A release paper may be used to cover the PSA when peeling the pouch open.

The sheets are cut from ribbons having at least one side edge which has a knee-like protrusion, with the opposing side edge being either, substantially parallel to the longitudinal axis of the ribbon, or having one or more knee-like protrusions formed on the opposing edge. The ribbons are then phased so that the knee-like protrusion on one edge aligns with either the essentially parallel edge of an adjoining ribbon or a knee-like protrusion on the side edge of the adjoining ribbon. Phasing can be accomplished by either, aligning knee-like protrusions on the side edges of adjoining ribbons, or reversing the orientation of the side edges of alternating ribbons. After phasing, the ribbons are overlapped creating a series of predetermined, areas of greatest overlap adjoining areas of least overlap such that successive ribbons are bonded only by the interfacial interaction between ribbons.

  • Patent number: 5535887
    Abstract: A tissue package comprising a plurality of tissues and a dispensing package. The plurality of tissues is compressed in two discrete stages, each of which stage can be released independently from the other. The first stage of compression is less than the second stage of compression. The tissues are transported and stored while under the second stage of compression. The user releases the second stage of compression, whereby the tissues can expand up to the first stage of compression. The user releases the first stage of compression just before installing the plurality of tissues into a dispensing package or dispenses the tissues through a restraint while they are held in the first stage compression.

  • Patent number: 5492962
    Abstract: Methods of producing particulate, absorbent, polymeric compositions comprising interparticle crosslinked aggregates. In the methods of the present invention, an interparticle crosslinking agent is applied onto precursor particles; the precursor particles are physically associated to form a multiplicity of aggregates; and the interparticle crosslinking agent is reacted with the polymer material of the precursor particles of the aggregates, while maintaining the physical association of the precursor particles, to form crosslink bonds between the precursor particles to form interparticle crosslinked aggregates. The interparticle crosslinked aggregates are formed to such an extent that the mass average particle size of the polymeric composition is at least about 25% greater than the mass average particle size of the precursor particles.
