The object of the invention is to provide a st~atd-up bag of the above type ptnvided with a discharge spout suitable for dt'inlang out of the bag.
The stand up bag according to the invention is characterised in that one of the side seams has as unsealed portion between the Y-fold of the bottom wall and the Y-fold of the top wall so as to pmvide an opeaimg, into which a filling pipe can be inserted for fr~hg the bag, and in that afb3r removal of the removable end portion the discharge spouthas an outer'width of less than or equal to 50 mm at least in the spout discharge portion provided by removing the removable end portion. As a result the bag is completely ready made with the acception of the said unsealed portion of one side seam, when the bag is filled with the liquid ptnduct to be packed there.
Especially, flee discharge spent with the discharge passage and the removable end portion have been formed before the liquid product is fiDad into the bag_ After filling of the bag only the side walls in the unsealed portion of said one side warns need be i5 sealed. Further aver ramaval of the removable end portion the outer discharge portion of the discharge spout may be inserted into n person's mouth or between n pezsan's lips, whereby the discharge spout serves as a drinknng spout Furthermore the narrow width of the spout and thus of the discharge passage allows a user to easy control the discharge of the contents of the bag, eg if the contents or a portion f has to be tcansfeaed to another container and the bag is txaned and pressure is applied thereto.
As every person has as individual mouth size end some people find it uncomfortable to insert large objects into their moutbs, sceording to the invention the outGC width of the discharge spout may be less than yr equal to 40 mm, preferably less than ox equal to 30 mm, and most preferably less thaw or equal to 25 xnm, at least in the spout discharge portion provided by removing the removable end portion. Decreasing discharge spout sizes make drinking out of the spout more pleasant for an increasing m~rber of par3vns, including children.

Furthermore according to the invention the width of the discharge passage may be such that the parts of the second top wall panel and the second side wall, respectively, forming the spout abut each other for closing the passage so as to prevent a liquid contained in the container and having a viscosity corresponding to the viscosity of water substantially from flowing out through the spout when the bag rests on the second side wall subsequent to the removal of the removable end portion. As a result user convenience is obtained in that the contents of the bag do not flow out, if the bag falls over or a user inadvertently places the bag on the second side wall after opening of the bag.
~ Moreover according to the invention the discharge passage has such a width that in order to make the liquid contained in the container flow out through the discharge passage, a certain amount of pressure has to be applied to the liquid product in the bag by squeezing the bag. The risk of unintended discharge of the liquid contained in the bag is thus minimized.
Moreover according to the invention the spout side seams may extend substantially parallel to each other so as to provide a discharge passage having the same flow area over its entire length.
According to yet another embodiment of the invention the spout side seams may, however, also extend in a substantially converging manner when seen in outward direction, whereby the effective flow area of the discharge passage is positioned at the discharge end of the spout. This embodiment of the invention is considered particularly advantageous in connection with more viscous or paste-like liquids such as sour dairy product, mayonnaise, ketchup and mustard, where a controlled discharge is desired.
According to a further embodiment of the invention the spout side seams may, however, also extend in a substantially diverging manner when seen in outward direction, whereby the smallest and effective flow area determines the volume flowrate LJ. n~ n~ LVVL IJ~J'T lrf7llJ IIUUL ~HICIVI

The cmbodinunt is thus considered particularly advantageous in cases, where the user is bo drink directly out of the spout, the desired comnlrination of volume flow rate and discharge velocity thereby being obtained, when the bag is squeezed.
Mvrmver acc~ng to the im~ention the bag may have an interior voh~me less than ar equal to one litre, but may also have au interior volume less than or equal tro 0.5 litres or less than or equal to O.ZS litres.
~rthermore according to the invention a weakened portion in form of as incision aadlor a laser perForstioa may be provided between the removable end portion and the discharge spout to obtain a defined rcmo~al of the r~a~ovable end portion.

The stand-up bag shown in Figs. 1 to 3 comprises a fizst silo wall l and a second side wall 2 a=raaged opposite each other and a top wall 3 and a bottom wall 4 also arranged opposite each other. The side walls 1,2 are sealed rogethct by means of side scaling seams 5,6 extending along two opposod side edges. The bottom wall 4 is folded inwards along a bottom wall fold 13 and sealed to the side walls 1,2 along two opposed transverse bottom seams 7, 8. The bottom wall panels 4a, 4b are sealed together and also sealed to the side walls 1,2 along the bottom side seams 9,10 aligned with the side scams 5,6.
In a coweapanding manur.,r the top wall is folded inwards into v-shape along a top wall fold 14 and thus comprises a first top wall panel 3a and a second top wall panel 3b. The two top wall panels 3a, 3b are sealed together and sealed to the first side wall and the second side wall, respectively, along bop side seams 15,16 aligned with the side seams 5,6. The first top wall panel 3a is sealed to the first side wall 1 along a t~ansvetse top sealing 11. The second top wall panel 3b and the second side wall 2 arc sealed together 1S along transverse aligned top seam portions 12a, 12b, an unsealed central area being provided ther8between. The second top wall panel 3b and the second side wall 2 both exbandbeyvnd the upper transverse top seam portions 12a,12b, which are $ush with the upper transverse top seam 11. The cxteneion 17 of the second top wall panel 3b and the e~atensioa 18 of the second side wall 2 are sealed together to form a discharge spout 19 having a discharge psasag~o 20. The discharge passage 20 is sideways defined by the spout side seams 21,22 c~nu~ected to the respective upper transverse top seam portion 12a and 12b. The discharge passage 20 is closed by meats of a seating seam Z3 inbercoanecting the spout side seams 21, 22 nn an voter removable end portion providing the passage with a discharge apa~g 25 when removed. In the embodiment shown in figs. 1-3, the discharge spout 19 is provided with an incision 26 for easy and well-definad xemoval of tfie removable end portion 24, In order for the discharge spout 19 to serve as a drinking spout aRer the removable discharge portion 24 has been removed, the sport has an outer width B in the discharge AMENDED SHEET

portion 27 cinder the incision 26 preferably of less than 30 mm and a projecting length L preferably exceeding 10 mm. The Shape sail size of the removable end portion 24 may be altered in any way, as it has no influence on the function of the discharge spout 19 as a dtinicing spout. ~ .
In the almbodimeat shown in Figs. 1-3 the spout side seams 21, 22 extend substantially parallel such that the discharge passage 20 has a substantially aanstant effective $ow aroa. "T6te chosen effective flow area preferably corrospoads to an effective passage width b preferably less than or equal to 15 Win, most preferably less than or equal to 10 mai, a suitable combination of the volume flow rate through ~e passage and the discharge velocity from tho passage being obtained thereby. At a suitably small effective passage width, a self-sealing passage is obtained in the sense that the wall portions of the passage abut each other substmntially so as to prevent liduid having a viscosity corresponding to that of water from flowing out of the, passage, when pressure is not applied to the liquid contained in the bag by squeezing the latter when it horizontally positioned.
Figs. I and 2 further illustrate a prefabricated bag according to the invention for the maaof the bag . The prefabricated bag is idc>otical to the shown bag with the exception that the silo seam 6 has a unsealed area 30 bdween the bottom wall fold I3 of the bottom wall 4 sad the top wall fold 14 of the top wall 3, said area 30 being betty~ea the lines 3 I and 32. In fig. 1 the imsealad area is further illustrated by means of dotted lines between the lines 31 sad 32. The unsealed area 30 of $e side seam 6 between the side walls 1 and 2 foams an opening 33 into the iateriar of the bag. A
filling tube for filling the prefabricated bag may be inserted through the apeni~g 33.
Subsequent to filling of the prefabricatedbag the filling opening 33 is closaiby sealing the side walls 2 bogother in the unsealed area 30 of the side ses~aa 6. ' ' As ahawn in Figs. 1 and 2, the bag may fiudicr be provided ~rith oblique bottom side searAS 34, 35, 36, 37 Extending from a level of the side seams 5,6 coaasponding to the AMENDED SHEET
Em~f .ze a t :29/04. «.~ 1,,..~, rm~r .nr .: ~ r~ t-.uxi bottom wall fold 13 and between a side seam 5,6 and a transverse bottom seam 7,8.
Each of the oblique seams 34-37 comlects a bottom wall panel 4a,4b to the adjacent side wall 1,2. The provision of the oblique bottom side seams 34-37 makes it possible to cut away the corner portions of the side walls 1,2 and corner portions of the bottom wall 4, said corner portions of the side walls being positioned outside of these oblique seams. Naturally, the top wall 3 may be connected to the side walls 1,2 by means of corresponding oblique top side seams.
Referring now to Fig. 4, in which a bag is diagrammatically shown comprising a discharge spout 39 having spout side seams 41,42 extending from the top seams portions 32a,32b so as to define a discharge passage 40 converging when seen in outward direction. The effective sectional area of flow of the discharge passage is thus determined by the inner width b of the passage 40 at the discharge opening 45 provided when the removable end portion 33 has been torn off along the tear line defined by the .
tear incision 46.
Advantageously, the width and then projecting length of the discharge spout 39 correspond to the width and length of the above discharge spout 19.
Fig. 5 is a diagrammatic view of a bag according to the invention, said bag comprising a discharge spout 59 with spout side seams 61,62 extending such from the upper top seam portions 52a,52b so as to define a discharge passage 60 substantially diverging when seen in outward direction. The smallest width b or the effective flow area of the discharge passage 60 is thus spaced apart from the discharge opening 65 formed by tearing off the removable end portion 64 along the tear line defined by the tear incision 66. The width b of the discharge passage 60 may for instance be between 6 - 10 mm and the width of the passage in the discharge opening 65 may for instance be 15 mm.
The outer width and the projecting length of the discharge spout 59 is advantageously as described above with reference to the discharge spout 19.
~ Moreover according to the invention the discharge passage has such a width that in order to make the liquid contained in the container flow out through the discharge passage, a certain amount of pressure has to be applied to the liquid product in the bag by squeezing the bag. The risk of unintended discharge of the liquid contained in the bag is thus minimized.
Moreover according to the invention the spout side seams may extend substantially parallel to each other so as to provide a discharge passage having the same flow area over its entire length.
According to yet another embodiment of the invention the spout side seams may, however, also extend in a substantially converging manner when seen in outward direction, whereby the effective flow area of the discharge passage is positioned at the discharge end of the spout. This embodiment of the invention is considered particularly advantageous in connection with more viscous or paste-like liquids such as sour dairy product, mayonnaise, ketchup and mustard, where a controlled discharge is desired.

Figs. I and 2 further illustrate a prefabricated bag according to the invention for the maaof the bag . The prefabricated bag is idc>otical to the shown bag with the exception that the silo seam 6 has a unsealed area 30 bdween the bottom wall fold I3 of the bottom wall 4 sad the top wall fold 14 of the top wall 3, said area 30 being betty~ea the lines 3 I and 32. In fig. 1 the imsealad area is further illustrated by means of dotted lines between the lines 31 sad 32. The unsealed area 30 of $e side seam 6 between the side walls 1 and 2 foams an opening 33 into the iateriar of the bag. A
filling tube for filling the prefabricated bag may be inserted through the apeni~g 33.
Subsequent to filling of the prefabricatedbag the filling opening 33 is closaiby sealing the side walls 2 bogother in the unsealed area 30 of the side ses~aa 6. ' ' As ahawn in Figs. 1 and 2, the bag may fiudicr be provided ~rith oblique bottom side searAS 34, 35, 36, 37 Extending from a level of the side seams 5,6 coaasponding to the AMENDED SHEET
Em~f .ze a t :29/04. «.~ 1,,..~, rm~r .nr .: ~ r~ t-.uxi bottom wall fold 13 and between a side seam 5,6 and a transverse bottom seam 7,8.
Each of the oblique seams 34-37 comlects a bottom wall panel 4a,4b to the adjacent side wall 1,2. The provision of the oblique bottom side seams 34-37 makes it possible to cut away the corner portions of the side walls 1,2 and corner portions of the bottom wall 4, said corner portions of the side walls being positioned outside of these oblique seams. Naturally, the top wall 3 may be connected to the side walls 1,2 by means of corresponding oblique top side seams.
Referring now to Fig. 4, in which a bag is diagrammatically shown comprising a discharge spout 39 having spout side seams 41,42 extending from the top seams portions 32a,32b so as to define a discharge passage 40 converging when seen in outward direction. The effective sectional area of flow of the discharge passage is thus determined by the inner width b of the passage 40 at the discharge opening 45 provided when the removable end portion 33 has been torn off along the tear line defined by the .
tear incision 46.
Advantageously, the width and then projecting length of the discharge spout 39 correspond to the width and length of the above discharge spout 19.
Fig. 5 is a diagrammatic view of a bag according to the invention, said bag comprising a discharge spout 59 with spout side seams 61,62 extending such from the upper top seam portions 52a,52b so as to define a discharge passage 60 substantially diverging when seen in outward direction. The smallest width b or the effective flow area of the discharge passage 60 is thus spaced apart from the discharge opening 65 formed by tearing off the removable end portion 64 along the tear line defined by the tear incision 66. The width b of the discharge passage 60 may for instance be between 6 - 10 mm and the width of the passage in the discharge opening 65 may for instance be 15 mm.
The outer width and the projecting length of the discharge spout 59 is advantageously as described above with reference to the discharge spout 19.
