摘要： A substance delivery system has a three dimensional structure with outermost surface features and spaces for containing a substance. The substance has a level below the outermost surface features such that the substance is protected from inadvertent contact with external surfaces. The substance remains protected until the three dimensional structure is sufficiently deformed into a substantially two dimensional structure and the substance is thereby exposed to contact an external surface without compliance of the external surface being necessary. Deforming is preferably achieved by a compression force, wherein the outermost surface features of the three dimensional structure deform in a direction of the compression force. A method of making the three dimensional material includes the steps of coating a substance onto a forming surface, transferring the coating of substance from the forming surface to a piece of material, and forming the piece of material into a three dimensional structure on the forming surface while the substance is in contact with the forming surface.

摘要： A method of making a gas permeable material having a diffusive gas permeability at 0.21 atmosphere diffusive driving force in the range of about 0.5.times.10.sup.5 cm.sup.3 /100 square inches/day to about 2.times.10.sup.5 cm.sup.3 /100 square inches/day. The method comprises the step of coating a pattern of spots of a gas impermeable material onto a porous substrate, followed by a step of enlarging the pattern of spots to cover greater than about 95% of the porous substrate such that the gas permeability occurs only through openings between the pattern of spots. The gas impermeable material is preferably a hot melt adhesive and the porous substrate is preferably a nonwoven. The step of enlarging the pattern of spots includes smearing substantially circular spots into oblong spots as the pattern of spots is printed onto the porous substrate until the oblong spots partially overlap. The smearing is achieved by operating a printing screen at a surface speed higher than a draw rate of the porous substrate. Alternatively, the step of enlarging the pattern of spots includes calendering through a fixed gap the porous substrate after the pattern of spots is coated thereon.

摘要： A method for making a flexible film having pressure sensitive adhesive protected from inadvertent adherence. The method coats a forming screen with an interconnected layer of pressure sensitive adhesive and places a piece of flexible film in contact with the layer of adhesive. The layer of adhesive preferentially adheres to the piece of flexible film. The forming screen has a plurality of recesses therein. The coating step applies the layer of adhesive without bridging the recesses. Another step forms the piece of flexible film to create a plurality of protrusions extending into the recesses. The plurality of protrusions are registered with the interconnected layer of pressure sensitive adhesive by virtue of using the same screen to transfer adhesive and to form protrusions. The forming screen may be wrapped around a rotating drum and the piece of flexible film may be a portion of a continuous web of flexible film. Preferably, the plurality of protrusions are conical, with a base diameter of 0.015 inches to 0.030 inches, a center-to-center spacing of 0.03 to 0.06 inches, and a protrusion height of 0.004 to 0.012 inches.

摘要： A composite material for controlling oxygen flux into a thermal cell comprises a bottom sheet formed to have a pocket. The bottom sheet is impermeable to oxygen. A plurality of particles is placed in the pocket. The plurality of particles reacts exothermally when exposed to oxygen. A top sheet is sealed to the bottom sheet at a flange around the pocket to enclose the plurality of particles such that the particles cannot fall out of the pocket. The top sheet has a substrate which is highly permeable to oxygen. The substrate is coated with an oxygen permeable silicone based elastomer to a thickness which regulates an oxygen flux into the pocket when the top sheet is exposed to oxygen. The composite material further comprises an oxygen impermeable barrier film bonded to the top sheet by pressure sensitive adhesive for preventing exposure of the top sheet to oxygen until the body warmer is intended to be used. A method for making a top sheet material involves coating a silicone rubber layer onto a smooth surface, partially curing the silicone, pressing a porous substrate against the silicone rubber layer, and completely curing the silicone rubber such that it adheres to the substrate.
