Tubular Bag and Method For Filling It

Abstract

Tubular pouch ( 10 ) having a spout ( 13 ) sealed-in in the region of a top sealing seam ( 12 ) and having a stand-up base ( 11 ). The top sealing seam ( 12 ) is unsealed at at least one location ( 14, 15 ) between the spout ( 13 ) and the outer edge (partial sealing), so that, when the pouch ( 10 ) is being filled, air can escape from the pouch ( 10 ) to the outside (arrow 16 ) through that unsealed location ( 14, 15 ).

1 . A stand-up or other tubular pouch, said pouch having an outer edge, a top sealing seam and a pourer or spout sealed-in in the region of said top sealing seam, wherein at least one unsealed location is provided in said top sealing seam between said spout and said outer edge to allow air to escape from said pouch to the outside through said at least one unsealed location when said pouch is being filled. 
   
   
       2 . A tubular pouch according to  claim 1 , further including a stand-up or other base. 
   
   
       3 . A tubular pouch according to  claim 1 , wherein said top sealing seam has at least one unsealed location on each side of said spout. 
   
   
       4 . A method of filling a tubular pouch according to  claim 1 , comprising the steps of filling said pouch with liquid, paste-form or pourable pouch contents through said spout or an opening formed therein, and allowing air in the interior of the pouch to escape to the outside through said at least one unsealed location in said top sealing seam during filling, and, after said pouch has been filled, sealing said at least one unsealed location of the top sealing seam to provide fluid-tight closure.
