Bag filler spout

A filler spout for use in feeding a stream of flowable material into a closed end multi-wall bag to facilitate insertion of the spout into the bag without damaging the inner wall thereof, and to ensure a constant volume passage for exhaust from the bag as the bag is filled by the flowable material, said spout comprising:

• (a) an outer tubular shroud member having a blunt curvilinear closed end and an opposite open end, an exhaust port formed in the side wall of the shroud member, and a discharge opening formed in the side wall of said shroud member intermediate said blunt curvilinear closed end and said exhaust port;
• and
• (b) an open ended material delivery tube disposed within the bore of said shroud member and spaced from the wall thereof so as to define an exhaust passage, one end of said exhaust passage being in communication with said exhaust port and the other end of said exhaust passage opening to ambient surroundings through the open end of said shroud member, said delivery tube having an inlet end adapted for connection with a material impelling machine, and an outlet end disposed contiguous to said discharge opening of said shroud member, said inlet end of said delivery tube projecting outwardly beyond said open end of said shroud member, said delivery tube having a first straight line portion extending from said inlet end into said shroud member and a second curvilinear portion extending from said first portion to said outlet end, said delivery tube being operable to divert the direction of a stream of material impelled therethrough approximately 90.degree. from said inlet end to said outlet end whereby said exhaust passage is maintained at a constant volume by said shroud member and whereby said closed curvilinear blunt end of said shroud facilitates entry of the spout into the bag without damaging the inner wall thereof.
