An oxygen-absorbing composition for absorbing oxygen from an enclosure, such as a package, containing a low-moisture product having an equilibrium relative humidity, or water activity, of between 30% and 90% including in relatively sufficient proportions for absorbing oxygen in the container, particles of iron, particles of a solid electrolyte material, and particles of hydrogel.

Oxygen absorber for low moisture products

A method of attaching a membrane across an opening of an annular deformable wall including the steps of placing a disc across the opening with the disc extending outwardly beyond the wall, and deforming the outer edge of the disc and the wall simultaneously by applying heat and pressure thereto to fuse the outer edge of the disc onto the wall.

Method of fabrication of a container for bulk material

A combined controlled rate adsorbent and disc drive stabilizing unit in the shape of a computer disc including an adsorbent of planar shape, a casing of porous material having a predetermined water vapor transmission rate encasing the adsorbent for prolonging the water vapor adsorption time of the adsorbent, and a self-sustaining jacket on the casing of a shape for installation into a computer disc drive during transit.

Controlled rate adsorbent and disc drive stabilizing unit

A controlled rate adsorbent unit including an adsorbent and a heat-shrunk casing of porous material having a predetermined water vapor transmission rate encasing the adsorbent for prolonging the water vapor adsorption time of the adsorbent. The controlled rate adsorbent unit may be in the shape of a recording disc or it may be in the shape of a three-dimensional solid with the heat-shrunk casing stretched tightly thereover. A method of fabricating a controlled rate adsorbent unit including the steps of providing an adsorbent material, heating the adsorbent material to dry off moisture therefrom, providing a porous material having a controlled water vapor transmission rate, sealing the adsorbent material in a casing of the porous material, heat-shrinking the porous material about the adsorbent, and storing the sealed adsorbent material in a moisture barrier package.

Controlled rate adsorbent unit and method of fabrication thereof

A container for material such as desiccant, adsorbent, absorbent or the like, including a molded shell made of high density polyethylene having a cylindrical side wall and an end wall and an open end, and a permeable membrane closing the open end by extending over onto the edge of the side wall and being deformed therewith and fused thereto into a frustoconical shape. A method of attaching a membrane across an opening of an annular deformable wall including the steps of placing a disc across the opening with the disc extending outwardly beyond the wall, and deforming the outer edge of the disc and the wall simultaneously by applying heat and pressure thereto to fuse the outer edge of the disc onto the wall. A container having a shell of the above-described type wherein the permeable membrane is secured to the end of the cylindrical side wall, and the overhanging portion of the membrane is sealed to the adjacent edge of the side wall which is deformed into a frustoconical shape.
