A packaging pouch (10) with an integral drinking straw or pouring spout (38,42) and an easy-to-open protective region providing access to the drinking straw or pouring spout, features a first compartment (32) to accommodate the contents e.g. a drink and—separated in a fluid-tight manner—a second compartment (34) to accommodate a tube part (42). The tube (38, 42) leads from the first compartment (32) to the second compartment (34) and is joined in the transition region to the pouch (10) in a fluid-tight manner and features a valve element for opening and closing a through-flow channel (37). At the end projecting into the second compartment the tube features a closure (44,46) which is closed in a fluid-tight manner when the pouch is in the unopened state and contains a valve element (58, 56) which, under the action of pressure from the side, frees a through-flow channel (37) and which closes automatically.
A packaging pouch (10), having two opposing walls, with a tube (38, 42) for drinking or pouring and an easy-to-open protective region as access to the tube (38, 42), which is located inside of the packaging pouch (10), comprises a first compartment (32) that contains fluid contents and, a second compartment (34) in which a first tube part (38) is located, that is separated in a fluid-tight manner from the first compartment (32) by means of transition region (30) formed by joined portions of inside surfaces of the two opposing walls of the pouch, where the tube (38, 42) is joined in the transition region (30) to inside surfaces of the two opposing walls of the packaging pouch (10) in a fluid-tight manner, leads from the first compartment to the second compartment and comprises a valve element for opening and closing a through-flow channel (37), the valve element (58, 56) is positioned in the portion of the tube (38, 42) which is located in the transition region (30) and, under the action of pressure from the side, frees the through-flow channel (37) and closes automatically.
A packaging pouch (10), comprises two opposing walls, with a tube (38, 42) for drinking or pouring, a seal portion of the pouch (10) which separates the pouch (10) in a fluid-tight manner into a first compartment (32) and a second compartment (34), an extending item (66) that is located in a fluid-tight manner in the seal portion and extends into the second compartment (34), a locking piece (72) is located on the extending item (66) that extends into the second compartment (34), the first compartment (32) contains fluid contents of pouch (10) and a tube part (38), the tube (38, 42) extends in a fluid-tight manner through a passageway (68) in extending item (66), the second compartment (34), pouches provide an easy-to-open protective region for access to a tube part (42) that is located in an projects into the second compartment (34), the tube part (42) of the tube (38, 42) has a fold (64) that effectively prevents the flow of fluid through the tube (38, 42) when pouch (10) is in the unopened state and, after opening the pouch (10), permits flow through the tube (38, 42) by straightening out end piece of the tube part (42), the locking piece (72) secures the end piece (43) of the tube portion (42) in the folded position.
