Abstract: A carrier for particulate material, comprising a pair of elongated rigid bars which are attached to opposite side edges of a sheet of planar flexible material. The dimension of one end edge of the sheet of flexible material is substantially less than the opposite end edge thereof, so that when the carrier is in the fully extended position, so that all elements lie in the same plane, the two rigid bars taper toward each other from the wide end of the sheet to the narrow end of the sheet.
