Disclosed is an improved apparatus for facilitating the filling of flexible containers. The apparatus consists of a substantially rigid, frustoconical tubular structure, somewhat smaller, in transverse dimension, than the transverse dimension of the flexible container to be filled. Means are provided for holding the apparatus when material is loaded through it into the container, and longitudinal grooves are provided in the outer surface of the apparatus to permit the release of air from the container as it is being filled.

The apparatus for facilitating loading of bulk materials into a flexible container having an opening, comprising a solid, one-piece shell-like structure having: a longitudinal axis; an upper end; a lower end, said upper end having a cross-sectional area greater than that of said lower end; and a gripping rim proximate to said upper end, said gripping rim extending around the entire outer circumference of said shell-like structure, said rim being substantially wider, as measured longitudinally along the shell-like structure, than its thickness, as measured radially from said longitudinal axis; said shell-like structure provided, on its outer surface, with a plurality of longitudinal grooves, said grooves extending toward said upper end from a point in proximity to said lower end.
