A resealable pouring spout for a bag, the spout having a pouring spout body (2) configured to be welded to the bag, a flange (3), a cutting device (1) having a flange-side cutting system (4), and a screwable sealing cap (5) on the pouring spout body (2). The pouring spout is configured to turn and displace the cutting device in a direction of the flange when the sealing cap is opened for the first time, and thereby cut open the bag.

1. A resealable pouring spout for a bag made of flexible film, wherein the resealable pouring spout comprises a pouring spout body (2), which is configured to be welded to the bag and has a flange (3), a cutting device (1) disposed in the pouring spout body and having a flange-side cutting system (4
1. A resealable pouring spout for a bag made of flexible film, wherein the resealable pouring spout comprises a pouring spout body (2), which is configured to be welded to the bag and has a flange (3), a cutting device (1) disposed in the pouring spout body and having a flange-side cutting system (4), and a screwable sealing cap (5) on the pouring spout body (2), and wherein the pouring spout is configured to turn and displace the cutting device in a direction of the flange when the sealing cap is opened for the first time, and thereby cut open the bag in a region of the flange, wherein the cutting system (4) of the cutting device (1) has at least one cutting tooth group (11) extending over a part of a cutting circle circumference,wherein the cutting tooth group (11) respectively has a number of cutting teeth (12, 12a),wherein the cutting teeth of the cutting tooth group (11) are arranged such that a leading cutting tooth (12a) in a cutting direction protrudes farthest in an axial direction (A), and further cutting teeth (12), following on from the leading cutting tooth (12a), of the cutting tooth group (11) protrude on a continually decreasing scale less far in the axial direction (A), andwherein the leading cutting tooth (12a) in the cutting tooth group (11) has a flattening (13a) running parallel to the flange (3), and in that the further cutting teeth (12), following on from the leading cutting tooth (12a), of the cutting tooth group (11) have constantly diminishing flattenings (13) following an equal course. 2. The resealable pouring spout as claimed in claim 1, characterized in that the leading cutting tooth (12a) in the cutting direction has frontally in the cutting direction (S) an inclined chamfer (14) on the flattening (13a), which chamfer avoids premature penetration of the flexible film. 3. The resealable pouring spout as claimed in claim 2, characterized in that the chamfer (14) opens out in an extensively tapered manner into a cutting edge (15) running substantially parallel to a rotational axis of the cutting device (1). 4. The resealable pouring spout as claimed in claim 3, characterized in that the cutting device (1) has a partially cylindrical body (10), and the cutting edge (15) lies in an outer face of the partially cylindrical body (10). 5. The resealable pouring spout as claimed in claim 3, characterized in that the cutting system (4) of the cutting device (1) has in a sector of the cutting circle circumference an outflow recess. 6. The resealable pouring spout as claimed in claim 5, characterized in that the cutting system (4) has a plurality of cutting tooth groups (11), and the cutting tooth groups are arranged distributed over at least three-quarters of the cutting circle circumference in order to approximately balance axially acting forces in a penetration operation. 7. The resealable pouring spout as claimed in claim 1, characterized in that the cutting system (4) of the cutting device (1) has in a sector of the cutting circle circumference an outflow recess. 8. The resealable pouring spout as claimed in claim 1, characterized in that the cutting system (4) has a plurality of cutting tooth groups (11), and the cutting tooth groups are arranged distributed over at least three-quarters of the cutting circle circumference in order to approximately balance axially acting forces in a penetration operation.
