Abstract: The present invention relates to a filter bag holder comprising a flexible tubular member having a relatively constant outside diameter throughout a substantial portion of its length to one of its axial ends and having two axially spaced annular ribs protruding from the outside of the tubular member near its other axial end. The constant-diameter end may be attached to a filter bag, and the ribbed end engages in the region between the two axially spaced protruding annular ribs with a rim around an aperture in a partition located between mediums under different pressures.

Abstract: An eight-sided foldable container having a bottom of the glued-automatic variety is disclosed. The container is constructed from a single sheet of foldable material which comprises eight side panels, a plurality of which are provided with bottom panels which extend angularly downwardly from the side panels via fold lines. These bottom panels are folded inwardly at their respective fold lines toward the center of the formed container such that two pairs are bonded together so as to enable the remaining bottom panels to interlock with and be supported by said bonded bottom panels, thereby forming a container bottom capable of supporting substantial weight, as well as being folded to a relatively flat condition. The blanks used for the construction of the container are also disclosed.
