Valve Bag

Abstract

The present invention relates to a valve bag for bulk material such as cement, gypsum, granulate, animal feed or similar, having a standing bottom, preferably a cross bottom or a block bottom, and having a valve bottom which is disposed opposite the standing bottom and into which a valve hose is inserted for filling the valve bag, wherein the valve hose is formed from a thermo material and a carrier material enveloping the thermo material, wherein the area proportion of the thermo material is smaller than the area proportion of the carrier material.

         3 . A valve bag ( 10 ) in accordance with  claim 2 , wherein the thermo material area in the region of the valve hose end facing the bag interior is shortened with respect o the carrier material ( 70 ). 
     
     
         4 . A valve bag ( 10 ) in accordance with  claim 1 , wherein the carrier material ( 70 ) substantially comprises a natural material, in particular paper. 
     
     
         5 . A valve bag ( 10 ) in accordance with  claim 1 , wherein the valve hose ( 50 ) has an almost constant strength in the axial direction. 
     
     
         6 . A valve bag ( 10 ) in accordance with  claim 1 , wherein the region of the earner material ( 70 ) overhanging with respect to the thermo material ( 60 ) is reinforced. 
     
     
         7 . A valve bag ( 10 ) in accordance with  claim 1 , wherein the carrier material ( 70 ) is folded over for reinforcement. 
     
     
         8 . A valve bag ( 10 ) in accordance with  claim 7 , wherein the carrier material ( 70 ) is folded over in the full valve periphery at the valve end facing the bag interior. 
     
     
         9 . A valve bag ( 10 ) in accordance with  claim 3 , wherein the carrier material ( 70 ) substantially comprises a natural material, in particular paper. 
     
     
         10 . A valve bag ( 10 ) in accordance with  claim 2 , wherein the carrier material ( 70 ) substantially comprises a natural material, in particular paper. 
     
     
         11 . A valve bag ( 10 ) in accordance with  claim 10 , wherein the valve hose ( 50 ) has an almost constant strength in the axial direction. 
     
     
         12 . A valve bag ( 10 ) in accordance with  claim 9 , wherein the valve hose ( 50 ) has an almost constant strength in the axial direction. 
     
     
         13 . A valve bag ( 10 ) in accordance with  claim 4 , wherein the valve hose ( 50 ) has an almost constant strength in the axial direction. 
     
     
         14 . A valve bag ( 10 ) in accordance with  claim 3 , wherein the valve hose ( 50 ) has an almost constant strength in the axial direction. 
     
     
         15 . A valve bag ( 10 ) in accordance with  claim 2 , wherein the valve hose ( 50 ) has an almost constant strength in the axial direction. 
     
     
         16 . A valve bag ( 10 ) in accordance with  claim 15 , wherein the region of the carrier material ( 70 ) overhanging with respect to the thermo material ( 60 ) is reinforced. 
     
     
         17 . A valve bag ( 10 ) in accordance with  claim 14 , wherein the region of the carrier material ( 70 ) overhanging with respect to the thermo material ( 60 ) is reinforced. 
     
     
         18 . A valve bag ( 10 ) in accordance with  claim 13 , wherein the region of the carrier material ( 70 ) overhanging with respect to the thermo material ( 60 ) is reinforced.
