There is provided a rupturing system (200) for an aerosol-generating system, wherein the rupturing system (200) comprises a first tube (104) and a second tube (102), wherein the first tube (104) and the second tube (102) are movable relative to each other along a first motion path from a first position to a second position such that the defined volume is larger in the first position than in the second position. The rupturing system (200) further comprises a rupturing member (114) connected to one of the first tube (104) and the second tube (102), wherein the rupturing member (114) is arranged such that in the first position the rupturing member (114) is contained completely in the defined volume of the first tube (104) and the second tube (102), and wherein in the second position the rupturing member (114) at least partially protrudes from the defined volume to rupture a container. The rupturing system (200) also comprises a first wrapper (402; 502) overlying at least a portion of the first tube (104), wherein the first wrapper (402; 502) is attached to the first tube (104).
