Abstract: The present invention provides a flexible storage bag having an opening and a color indicating element adjacent to the opening, a mechanical interlocking seal for closing the opening, and a slider for sealing the mechanical interlocking seal. The slider includes an aperture, and the color indicating element is viewable through the aperture when the slider reaches a position along the mechanical interlocking seal to register the aperture with the color indicating element. The color indicating element is preferably positioned adjacent to an end of the mechanical interlocking seal, preferably positioned so as to indicate that the mechanical interlocking seal has been fully closed. The color indicating element may be a plastic insert of a different color than its surroundings or may be printed or painted in place.

Abstract: The strength of lignocellulosic materials is improved by treating them with water-soluble strengthening agents containing sulfonic units, and rendering these agents water-insoluble by reacting them with compounds containing azetidinium rings. Thus, a substantial reduction or elimination of the bleeding of said strengthening agents from the lignocellulosic materials when touched with wet hands or contacted under humid conditions is achieved.

Abstract: An ultrasonic atomizer is provided including an ultrasonic vibrator, a reservoir, and a heat exchanger. The ultrasonic vibrator is connected to an amplifying section. The amplifying section has an exterior surface and a tip thereon. The amplifying section can be elongated and the amplifying section can be inclined at an angle that is preferably between about 5.degree. to 10.degree. from horizontal. The reservoir is in fluid communication with the exterior surface of the amplifying section. The reservoir contains a liquid. A pump can be located between the reservoir and the exterior surface of the amplifying section in order to assure a liquid flow rate of between about 10 to about 30 ml/min. The heat exchanger is provided in order to control the temperature and viscosity of the liquid. The liquid is directed to flow from the reservoir and over the exterior surface of the amplifying section to the tip. A feed tube having a dispensing end can be provided.

Abstract: The present invention provides a selectively-activatible sheet material for delivering a substance to a target surface. The sheet material comprises a three-dimensional sheet of material having a first side and a second side. The first side has a plurality of hollow protrusions extending outwardly therefrom and separated from one another by valleys, while the second side has a plurality of depressions corresponding with the hollow protrusions. A substance adheres to and partially fills a location protected from external contact comprising the valleys and/or depressions. The sheet material may be selectively activated by deforming the hollow protrusions to deliver the substance to a target surface. The three-dimensional structure includes hollow protrusions which are adapted to progressively activate in multiple discrete stages to effect multistage progressive delivery of the substance to the target surface.

Abstract: A high pressure manually-actuated spray pump for dispensing a fluid. The spray pump comprises a nozzle through which the fluid is dispensed and a pumping engine. The pumping engine comprises a reservoir, a closure, and a plunger. The reservoir has an open top and a closed bottom and an interior surface. The plunger has an outer surface and a longitudinal passageway extending therethrough. The plunger further having an outlet valve mounted therein and an upper end and a lower end. The lower end being slidably disposed within the open top of the reservoir forming an interior chamber within the reservoir. The interior chamber has an annular chamber and a main chamber. The annular chamber being in fluid communication with the main chamber. The annular chamber is formed by the outer surface of the plunger being spaced away from the interior surface of the reservoir such that there is no frictional contact between the outer surface and the interior surface.

Abstract: The present invention provides a dispensing pump for dispensing a plurality of fluids simultaneously but separately through a spout. The spout has a plurality of discharge orifices and a closure associated with the spout for closing the discharge orifices. The closure is sized and adapted to seal all discharge orifices and further includes at least one plug seal for sealing at least one respective discharge orifice but has fewer plug seals than discharge orifices.

Abstract: A package comprising an array of at least two substantially parallelepipedal packs, the packs including compressed flexible articles encased in a flexible bag, and a flexible paper covering disposed adjacent the whole of the bottom panel of the array and a substantial part of the side panels of the array corresponding to at least 30 percent of the height of the array. The paper covering is held under tension around the array so as to create a strong and protective outer casing for the array.

Abstract: Hair care compositions which provide improved styling and hair conditioning properties are disclosed. The compositions comprise from about 0.1% to about 10.0% of a specifically-defined silicone copolymer and from about 0.5% to about 99.5% of a carrier suitable for application to hair. These compositions are characterized by the fact that, when dried, the polymer phase separates into a discontinuous phase which includes a silicone macromer and a continuous phase which includes the copolymer backbone.

Abstract: The present invention relates to hair spray compositions comprising from about 0.01% to about 2% of an ionic surfactant or a nonionic surfactant having an HLB of about 7 or less; from about 0.5% to about 15% of an ionic resin having a weight average molecular weight of at least about 300,000; and a liquid vehicle. This invention further relates to hairspray compositions comprising from about 0.5% to about 15% of an ionic, silicone macromer-containing resin as the hair setting agent, a liquid vehicle comprising a mixture of water and monohydric alcohol solvent (e.g., C.sub.1 -C.sub.3 monohydric alcohols) wherein the composition contains at least about 10%, by weight of the composition, of water, and an ionic surfactant. Suitable surfactants are organic surfactant selected from the group consisting of anionic surfactants, amphoteric surfactants, zwitterionic surfactants, cationic surfactants, and nonionic surfactants having an average HLB of less than or equal to about 7.

Abstract: An aqueous hair setting composition, comprising: (a) from about 0.1% to about 15%, by weight, of a cationic, water soluble polymeric hair setting agent, said hair setting agent being a silicone macromer-grafted copolymer derived by polymerization of: (i) from about 1% to about 20%, by weight, silicone macromers; (ii) from about 5% to about 75%, by weight, nonionic, quaternizable monomers; and (iii) from about 5% to about 90%, by weight, nonionic, water soluble, non-quaternizable monomers; wherein at least about 5 wt/%, of the monomers, calculated by total weight of the copolymer, are quaternized and said copolymer has a backbone having a Tg of from about 30.degree. C. to about 140.degree. C.; and (b) from about 75% to about 99.9%, by weight, water.

Abstract: Disclosed is a vehicle system having a thickening system which comprises a nonionic long-chain alkylated water-soluble polymer and a specific cationic quaternary ammonium surfactant component dispersed in a compatible solvent. The quaternary surfactant component has an iodine value of at least about 15. The quaternary surfactant component is characterized by having a sufficient level of unsaturated C.sub.14 -C.sub.22 alkyl or C.sub.14 -C.sub.22 alkyl amido C.sub.2 -C.sub.6 alkylene radicals such that the average iodine value is at least about 15. These vehicle systems are useful in cosmetic compositions which are used to deliver an active component to the hair or skin. The vehicle systems are particularly useful in hair care compositions, especially rinse-off hair conditioning and styling compositions.
