Patent ID: 8028860

Claim:
A hermetically closed fluid bag ( 1 ) with an integrally welded-in, hermetically closed drinking spout or dispensing spout ( 2 ), whereby the fluid bag ( 1 ) forms two closed chambers ( 6 ; 7 ) including an upper bag chamber ( 7 ) and a lower bag chamber ( 6 ), and the two closed chambers are either separated from one another by a separating strip ( 8 ) on a single-piece bag, or are produced either by way of welding together two individual bags along the separating strip, or by producing the upper bag chamber ( 7 ) by putting over and shrinking on around the drinking spout or dispensing spout ( 2 ) which is welded into the lower bag chamber ( 6 ) and thereby said upper bag chamber ( 7 ) is welded together with said lower bag chamber ( 6 ), characterized in that the drinking spout or dispensing spout ( 2 ) in a closed condition is sealingly welded into the separating strip ( 8 ) so that the drinking spout or dispensing spout ( 2 ) connects the two chambers ( 6 ; 7 ) in an opened condition of the drinking spout or dispensing spout ( 2 ) and that a wedge-like lip spout ( 9 ) of the drinking spout or dispensing spout ( 2 ) either extends into the lower bag chamber ( 6 ) or into the upper bag chamber ( 7 ), and wherein the lower bag chamber ( 6 ) is envisaged for receiving a fluid, whilst the upper bag chamber ( 7 ) sealingly encloses an outlet side of the drinking spout or dispensing spout ( 2 ) as a protective chamber, and whereby said upper bag chamber ( 7 ) which works as the protective chamber is openable by hand; further that the drinking spout or dispensing spout ( 2 ) is in one piece, with a base ( 10 ) and the wedge-like lip spout ( 9 ) of rubber-elastic plastic, wherein a lip ( 14 ) at an end of the wedge-like lip spout ( 9 ) is closed hermetically via a thin location that can be torn open by mechanical action by hand or by mouth, by way of rotating the lip spout ( 9 ) or by way of pressing-together the lip ( 14 ) in a running direction of a lip line ( 16 ), or by inserting a drinking straw; and that the drinking spout ( 2 ) is provided with a push button ( 20 , 21 ), so that the lip spout ( 9 ) can be bent over and secured on a bent-over position by way of the push button.
