Pouch for fluid

Abstract

A pouch for fluid comprises: a first film ( 1100 ) and a second film ( 1200 ) connected to each other by means of a stronger seal ( 1300 ) and a weaker seal ( 2700 ) so as to form a cavity ( 1500 ) for a fluid, wherein the cavity ( 1500 ) has a perimeter and said perimeter comprises at least a part of the stronger seal ( 1300 ) and at least a part of the weaker seal ( 2700 ), and wherein the weaker seal ( 2700 ) is in proximity of the stronger seal ( 1300 ).

         12 . A pouch for fluid comprising:
 a first film and a second film connected to each other by means of a stronger seal and a weaker seal so as to form a cavity for a fluid,   wherein the cavity has a perimeter and said perimeter comprises at least a part of the stronger seal and at least a part of the weaker seal,   characterized in that the weaker seal is in proximity of the stronger seal.   
     
     
         13 . The pouch according to  claim 12 ,
 wherein the weaker seal and the stronger seal are configured such that the weaker seal opens only if at least a first portion of the stronger seal is opened or removed.   
     
     
         14 . The pouch according  claim 13 , further comprising an opening structure,
 wherein the opening structure is configured so as to facilitate opening of the first film and/or of the second film at least along a first length,   wherein the first length crosses at least the first portion of the stronger seal.   
     
     
         15 . The pouch according to  claim 14 , wherein the first length further crosses at least a part of the weaker seal. 
     
     
         16 . The pouch according to  claim 15 , wherein the first length crosses only parts of the first film and/or of the second film in which the stronger seal or the weaker seal are present. 
     
     
         17 . The pouch according to  claim 14 , wherein the opening structure comprises weakening points and/or holes made in the first film and/or in the second film. 
     
     
         18 . The pouch according to  claim 14 , wherein the opening structure is configured to facilitate cutting of the first film and/or of the second film so as to leave at least part of the weaker seal exposed to the ambient. 
     
     
         19 . The pouch according to  claim 12 , wherein the weaker seal has a length equal to or less than 50 mm and/or a width equal to or less than 5 mm. 
     
     
         20 . The pouch according to  claim 12 , wherein the first film and/or the second film comprise a blend of ionomer and polypropylene. 
     
     
         21 . The pouch according to  claim 12 ,
 wherein the stronger seal has a sealing strength above 15N/15 mm, and/or   wherein the weaker seal has a sealing strength of 1-8N/15 mm.   
     
     
         22 . A manufacturing method for a pouch for fluid, the method comprising the steps of:
 providing a first film and a second film,   connecting the first film and the second film to each other so as to form a for the fluid by realizing a stronger seal and a weaker seal,   characterized in that the weaker seal is made in proximity of the stronger seal.
