Container-handling apparatus with a transportation element

1. An apparatus comprising a container-handling machine that comprises a rotor that rotates around a machine axis, an inlet transporter that brings containers to said rotor, an outlet transporter that takes containers from said rotor, and a container-handling section that extends along a handling direction along which said containers move after having been taken from said rotor, wherein said rotor comprises handling positions and a transport element, wherein said transport element comprises pockets along a circumference thereof, wherein each of said pockets comprises a flank that forms a first abutment surface that abuts a container during motion thereof, wherein said container-handling machine further comprises a finger that is assigned to said pocket, and wherein said finger forms a second abutment surface that adjoins said first abutment surface and that extends in a radial direction away from said machine axis, said second abutment surface comprising a first section and a second section, the second section being either concave or convex and extending away from said machine axis.

2. The apparatus of claim 1 , wherein said second abutment surface is connected so as to be directly adjacent to said first abutment surface and to extend in a direction radially away from said machine axis.

3. The apparatus of claim 1 , wherein said container has a velocity, wherein said second abutment surface is shaped such said container, after leaving said pocket and while contacting said second abutment surface, said container's velocity is changed such that said container sustains a reduced centripetal acceleration relative to that sustained by said container while said container was moving with said pocket.

4. The apparatus of claim 1 , wherein said second abutment surface comprises a first section that connects to said first abutment surface to form a smooth curve with no inflection point.

5. The apparatus of claim 1 , wherein said finger is arranged to extend from a circumference of said transport element.

6. The apparatus of claim 1 , wherein said second section is concave.

7. The apparatus of claim 1 , wherein said second section is convex.

8. The apparatus of claim 1 , wherein said second abutment surface comprises a first section and a second section, wherein said second section is directly adjacent to said first section so as to form a continuous curve along said first and second sections.

9. The apparatus of claim 1 , wherein said wherein said second abutment surface comprises a first section and a second section, wherein said first section is concave and said second section is convex, whereby said second abutment surface imparts an acceleration that changes sign as said container moves between said first section and said second section.

10. The apparatus of claim 9 , wherein said second section is distal to said first section and said second section is configured as a clothoid.

11. The apparatus of claim 1 , wherein said second abutment surface comprises first, second, and third sections that extend away from said machine axis, wherein said second section connects said first and third sections and is adjacent to said first and third sections, wherein said first, second, and third sections are curved such that acceleration of said container changes sign in crossing between said first and second sections and changes sign again in crossing between said second and third sections.

12. The apparatus of claim 1 , wherein said transport element comprises said transport finger, wherein said container-handling machine comprises a guide rail that guides said container as said container disengages from said transport finger, and wherein said guide rail guides said container along said handling direction by abutting a side of said container to constrain said container from moving laterally and away from said handling direction.

13. The apparatus of claim 1 , wherein said outlet transporter comprises further transport fingers that move together in a lateral direction, wherein said second abutment surface causes a change in sign of an acceleration of said container to achieve a velocity that matches that of said transport fingers of said outlet transporter, thereby promoting jerk-free transfer of said container between said rotor and said outlet transporter.

14. The apparatus of claim 1 , wherein said container-handling machine comprises a filling machine.

15. The apparatus of claim 1 , wherein said container-handling machine comprises a closing machine.

16. An apparatus comprising a container-handling machine that comprises a rotor that rotates around a machine axis, an inlet transporter that brings containers to said rotor, an outlet transporter that takes containers from said rotor, and a container-handling section that extends along a handling direction along which said containers move after having been taken from said rotor, wherein said rotor comprises handling positions and a transport element, wherein said transport element comprises pockets along a circumference thereof, wherein each of said pockets comprises a flank that forms a first abutment surface that abuts a container during motion thereof, wherein said container-handling machine further comprises a finger that is assigned to said pocket, and wherein said finger forms a second abutment surface that adjoins said first abutment surface and that extends in a radial direction away from said machine axis, wherein said wherein said second abutment surface comprises a first section and a second section, wherein said first section is concave and said second section is convex, whereby said second abutment surface imparts an acceleration that changes sign as said container moves between said first section and said second section, and wherein said second section is distal to said first section and said second section is configured as a polynomial of order greater than or equal to two.

17. An apparatus comprising a container-handling machine that comprises a rotor that rotates around a machine axis, an inlet transporter that brings containers to said rotor, an outlet transporter that takes containers from said rotor, and a container-handling section that extends along a handling direction along which said containers move after having been taken from said rotor, wherein said rotor comprises handling positions and a transport element, wherein said transport element comprises pockets along a circumference thereof, wherein each of said pockets comprises a flank that forms a first abutment surface that abuts a container during motion thereof, wherein said container-handling machine further comprises a finger that is assigned to said pocket, wherein said finger forms a second abutment surface that adjoins said first abutment surface and that extends in a radial direction away from said machine axis, and wherein said second abutment surface comprises first, second, third, and fourth sections that extend away from said machine axis, wherein said second section is between said first and third sections, wherein said third section is between said second section and said fourth section, and wherein said sections are curved such that acceleration of said container changes sign when crossing between any two adjacent sections.
