A method for producing a container having a plurality of oral pouched snuff products contained in its interior space, said container having a base and a detachable lid together providing said interior container space, said method comprising:
- supplying and advancing at least one web of packaging material, said at least one web of packaging material advancing in a direction of travel, wherein the packaging material comprises a saliva-permeable material, and wherein the saliva-permeable material comprises a non-woven material;
- supplying a filling material to said at least one advancing web of packaging material;
- in a plurality of simultaneous ultrasonic welding and cutting operations, ultrasonically welding and cutting said at least one advancing web of packaging material to which the filling material has been supplied to provide a plurality of pouches enclosing the filling material,
- wherein for each of the plurality of simultaneous welding and cutting operations, said ultrasonic welding and cutting are performed simultaneously, thereby providing a welded area sealing a first end of a first pouch of the plurality of pouches and simultaneously sealing a second end of a second pouch of the plurality of pouches, and also simultaneously providing a cut in the welded area to separate the first pouch from the second pouch, wherein each of said simultaneous ultrasonic welding and cutting operations occurs at one position,
- wherein each of said simultaneous welding and cutting operations are performed by:
- passing the at least one web of packing material through a gap formed between a first operation surface and a second operation surface, wherein the first operation comprises a first welding surface and a second welding surface delimited by a cutting edge formed immediately between the first welding surface and the second welding surface;
- moving one or both of the first operation surface and the second operation in a main direction to close the gap, thereby contacting the first operation surface and the second operation surface to the at least one web of packaging material, whereby the first welding surface and second welding surface form the welded area on the at least one web of packaging material and the cutting edge simultaneously cuts the at least one web of packaging material in the welded area,
- each thereby provided oral pouched snuff product having a longitudinal direction extending between a first end and a second end, and a transverse direction perpendicular to said longitudinal direction, each pouch having a first elongated seal and a second elongated seal, each of said first and second elongated seals having a seal length extending along the transverse direction of the oral pouched snuff product and a seal width extending along the longitudinal direction of the oral pouched snuff product, said seal width being within the range of from 0.1 mm to 2 mm, said first elongated seal is sealing the first end of the pouch, and said second elongated seal is sealing the second end of the pouch, and each of said first elongated seal and said second elongated seal are coterminous with said first and second ends, respectively;
- and
- supplying the thereby provided plurality of oral pouched snuff products to the container.
