Tubular bag

Abstract

A tubular bag with cap closure for the accommodation of fluid foodstuffs, wherein the base of the bag is constructed especially as a standing base and is welded or sealed fluid-tight with the bag as a separate component along the base-end bag edge, wherein the tubular part of the bag is manufactured from a single cut of film, especially a cut of laminated film, the longitudinal edges of which are sealed one over the other to form a “lap seal” (inner/outer seal) or alternatively constructed as a “fin seal” (inner/inner seal). A cap closure that is part of a relatively stiff cover is welded or sealed fluid-tight with the upper or closure-end bag edge. The tubular bag according to the invention has an enhanced filling capacity and improved stability.

1 . A tubular bag with cap closure for the accommodation of fluid foodstuffs, wherein the base of the bag is constructed as a standing base and is welded or sealed fluid-tight with the bag as a separate component along the base-end bag edge, wherein the cap closure is part of a relatively stiff cover, which is fluid-tight welded or sealed with the upper or closure-end bag edge, and wherein the tubular part of the bag is plastically deformed within a mold to form a durable profile  
   
   
       2 . A bag according to  claim 1 , wherein the base is constructed from a relatively stiff or rigid or alternatively flexible disc, the circumferential edge of which is welded or sealed with the circumferential edge of the tubular part of the bag, which edge is deformed at its base somewhat radially towards the outside.  
   
   
       3 . A bag according to  claim 1 , wherein the cap closure comprises a screw cap.  
   
   
       4 . A bag according to  claim 1 , wherein the durable profile comprises a bulge.  
   
   
       5 . A bag according to  claim 1 , wherein the durable profile forms a barrel shape.  
   
   
       6 . A bag according to  claim 1 , wherein the durable profile forms a bullet shape.
