MULTI-PART PACKAGING WITH SEALED CONNECTION JOINT

摘要

Multi-part packaging (1) having a sealed-off connection joint (7), consisting of at least two packaging sleeves (2, 3) that can be inserted into one another on the end side, wherein on the end side, a connection sleeve (4) having a reduced diameter is formed onto the one packaging sleeve (2), which connection sleeve can be inserted, with shape fit, into an accommodation region (5) of the opposite connection sleeve (3), which region is adapted to the profile of this connection sleeve (4), thereby forming an insertion region (6) between the two packaging sleeves (2, 3), which region is formed, on the edge side, by a connection joint (7) that runs in the circumference direction and can be sealed off, in air-tight manner, by means of a sealing film (8) that is wound onto the connection joint in the circumference direction and sealed on there, wherein the end-side overlap edges (21, 22) of the sealing film (8) reciprocally overlap in a coverage region (23) that runs parallel to the longitudinal axis of the packaging sleeve (2, 3) in the axial direction, wherein the coverage region (23) of the sealing film (8) that runs in the axial direction is additionally sealed.
