Abstract: An article for the protection of humans, animals and other articles from damage due to undesired exposure to lasers comprising a tubular element comprising at least one layer comprising a xerogel comprising at least one water-insoluble hydrophilic polymer wherein if said tubular element comprises at least three layers the layer adjacent the distal side, relative to the laser beams, of said xerogel layer comprises a metallic layer the proximal surface of which may be reflective or nonreflective of the laser beams and wherein said xerogel layer may further comprise a pigment. In addition, the layer on the distal side of said metallic layer may be a xerogel. During use of the articles of the invention the xerogels thereof are in a hydrated condition, i.e., they are hydrogels.

Abstract: An article for generating foams from foamable liquids and pressurized gases comprising a housing encompassing a hollow porous element in fluid connection with the gas source through an inlet port in the housing, a mixing chamber comprising the space between the walls of the porous element and housing in fluid connection a source of the foamable liquid wherein the liquid and the gas diffusing thereto through the wall of the element mix to form the foam which is discharged without passing through pores the article further comprising, if desired, a valve to prevent entry of the gas to the porous element, and therethrough to mix with the liquid, whereby the liquid is dispensed in its liquid form.

Abstract: An article for use in brushing and scrubbing surfaces with flowable materials comprising an easily delaminable reservoir for said flowable materials which, as required, will supply the materials in unreduced strength to disposable scrubbing implements for the application of said materials to, and scrubbing and brushing of surfaces, said reservoir comprising:(a) a first member comprising a semi-rigid flat sheet; and(b) a formed second member comprising a cavity comprising a bottom wall, a circumferential side wall depending perpendicularly from said bottom wall and terminating at its upper end in a circumferential flange extending outward from said normal to said upper end and a top opening coplanar with the upper surface of said flange, the first and second members of said reservoir being delaminable upon the application of a slight pressure to said first member adjacent said cavity; wherein said first member is in adherent contact with said the flange of said second member adherence being effected by means o

Abstract: An applicator package for the application of flowable materials to surfaces, comprising: an applicator pad; a backing member, one surface of which is in adhesive contact with the pad, comprising a first, flexible sheet; a second member, in contact with the other surface of the backing member, comprising a formed semi-rigid sheet having at least one recess adjacent the pad; at least one cavity, or reservoir for flowable materials distally spaced from the recess; a peripheral groove in fluid connection with the recess and spaced from the distal and side edges of the member; co-planar separations, between the cavity and the groove and recess, in contact with the backing member the backing member being sealed to the second member at the periphery thereof and at the separations between the cavity, groove and recess; and an opening adjacent to and between the pad and the recess to permit the flow of the flowable materials therethrough into the pad and therethrough to the desired surfaces.
