Straw made from paper or paper-like material

A straw made from paper or paper-like material and comprising a tubular body having a circumference formed by a wall surrounding a central axis and a bendable part extending axially along the central axis, wherein:

• said bendable part comprises at least two corrugated profiles provided in the wall,
• each corrugated profile comprises inward corrugations and outward corrugations being positioned one after the other in axial direction along the central axis,
• the inward corrugations extend along only part of the circumference of the tubular body,
• the outward corrugations extend along only part of the circumference of the tubular body,
• at least one of the at least two corrugated profiles is circumferentially offset relative to at least one other of the at least two corrugated profiles,
• said at least one of the at least two corrugated profiles comprises inward corrugations which are located between two inward corrugations of said at least one other of the at least two corrugated profiles when seen in axial direction along the central axis, and
• said at least one of the at least two corrugated profiles comprises outward corrugations which are located between two outward corrugations of said at least one other of the at least two corrugated profiles when seen in axial direction along the central axis.

A system for producing a straw made from paper or paper-like material and comprising a tubular body having a circumference formed by a wall surrounding a central axis and a bendable part extending axially along the central axis, wherein the system comprises:

• a holding unit to hold the tubular body of the straw in an operation position,
• a profiling device comprising at least two series of push members which are positionable along the tubular body being held in the operation position,
• wherein:
• each of the at least two series of push members comprises multiple push members being spaced from each other in axial direction along the central axis of the tubular body,
• each push member is movable from a first member position in which the push member is spaced from the circumference of the tubular body into a second member position located closer to the central axis to push a contact part of the circumference of the tubular body coming in contact with the push member towards the central axis in order to form an inward corrugation extending along only part of the circumference of the tubular body,
• at least one of the at least two series of push members is positioned circumferentially offset in view of the tubular body relative to at least one other of the at least two series of push members,
• said at least one of the at least two series of push members comprises push members which are located between two push members of said at least one other of the at least two series of push members when seen in axial direction along the central axis of the tubular body, and
• the profiling device is configured to move the push members of the at least two series of push members from the first member position into the second member position to form with each series of push members inward corrugations being positioned one after the other in axial direction along the central axis and to move the inward corrugations of each of the at least two series of push members towards each other in axial direction along the central axis to form outward corrugations extending along only part of the circumference of the tubular body and between subsequent inward corrugations, thereby providing the bendable part to the tubular body, which bendable part comprises at least two corrugated profiles provided in the wall, wherein each corrugated profile comprises inward corrugations and outward corrugations being positioned one after the other in axial direction along the central axis.

A method for producing a straw made from paper or paper-like material and comprising a tubular body having a circumference formed by a wall surrounding a central axis and a bendable part extending axially along the central axis, said method comprises:

• providing the tubular body made from paper or paper-like material and having the circumference formed by the wall surrounding the central axis,
• positioning at least two series of push members along the tubular body, wherein:
• each of the at least two series of push member comprises multiple push members being spaced from each other in axial direction along the central axis of the tubular body,
• each push member is movable from a first member position in which the push member is spaced from the circumference of the tubular body into a second member position located closer to the central axis to push a contact part of the circumference of the tubular body coming in contact with the push member towards the central axis in order to form an inward corrugation extending along only part of the circumference of the tubular body,
• at least one of the at least two series of push members is positioned in view of the tubular body circumferentially offset relative to at least one other of the at least two series of push members,
• said at least one of the at least two series of push members comprises push members which are located between two push members of said at least one other of the at least two series of push members when seen in axial direction along the central axis of the tubular body,
• moving the push members of the at least two series of push members from the first member position into the second member position to form with each series of push members inward corrugations being positioned one after the other in axial direction along the central axis and moving the inward corrugations of each of the at least two series of push members closer to each other in axial direction along the central axis to form outward corrugations extending along only part of the circumference of the tubular body and between subsequent inward corrugations, thereby providing the bendable part to the tubular body, which bendable part comprises at least two corrugated profiles provided in the wall, wherein each corrugated profile comprises inward corrugations and outward corrugations being positioned one after the other in axial direction along the central axis.
