  • Patent number: 6749551
    Abstract: A container body with a container opening and a flap partially secured to the container body and completely covering the container opening is disclosed. The flap is secured to the container by a hinge or fold line and formed from the same substrate as the container body. The container body contains a first magnetic region adjacent to and surrounding the perimeter of the container opening. The flap contains a second magnetic region aligned with and opposite the container body's first magnetic region. The first and second magnetic regions are magnetically attracted to each other. The flap is held in a closed position by magnetic attraction between the flap's magnetic region and the container body's magnetic region.

  • Publication number: 20030118823
    Abstract: Product attrition by dusting of granular and shaped activated carbons is disclosed to be reduced significantly, or essentially eliminated, by the application of a thin, continuous polymer coating on the granular or shaped activated carbon, without a reduction in adsorption velocity or capacity of the activated carbon when used in fluid stream filters for removing contaminants. The avoidance of carbon dust leads to improved fluid stream filter performance in contaminant removal.
