Abstract
A multi-part packaging including at least two packaging sleeves and a sealing film that seals a connection joint between the packaging sleeves is disclosed. One of the two packaging sleeves includes an end region having a reduced diameter that can be inserted into an accommodation region of the other packaging sleeve forming the connection joint that runs in the circumference direction which can be sealed in an air-tight manner by means of the sealing film that is wound onto the connection joint in the circumference direction and sealed thereon. Edges of the sealing film overlap in a coverage region that runs parallel to a longitudinal axis of the packaging sleeves in the axial direction, wherein a first overlap edge conforms to a starting edge of a second overlap edge to form the air-tight seal.
Claims19
A multi-part packaging comprising:
- a first packaging sleeve that has a longitudinal dimension and a diameter dimension, the first packaging sleeve also having a face side that defines a profile and a circumferential edge located longitudinally away from the face side, the first packaging sleeve defining a connection sleeve between the face side and the circumferential edge with the connection sleeve having a diameter dimension that is less than the diameter dimension of the first packaging sleeve;
- a second packaging sleeve that has a longitudinal dimension and a diameter dimension, the second packaging sleeve having a longitudinal end that defines an accommodation region with a profile corresponding to the profile of the face side of the first packaging sleeve such that the connection sleeve of the first packaging sleeve is insertable in the accommodation region of the second packaging sleeve and, at times when the connection sleeve is inserted in the accommodation region, the first packing sleeve cooperates with the second packaging sleeve to establish a connection joint between the circumferential edge of the first packaging sleeve and the longitudinal end in the accommodation region of the second packaging sleeve;
- and
- a sealing film comprising a starting edge, an ending edge, and a length that is greater than the diameter dimension of the second packing sleeve, wherein the sealing film is located and sealed over the connection joint such that a first overlap edge comprising the ending edge covers a second overlap-edge comprising the starting edge to define a coverage region that runs in the longitudinal dimension of the first and second packaging sleeves, wherein a rear edge of the first overlap edge conforms to the starting edge of the second overlap edge forming an overlap step that is radially offset to provide an air-tight seal against the starting edge that runs in an axial direction.

A multi-part packaging comprising:
- a first packaging sleeve having a longitudinal dimension and a diameter dimension, the first packaging sleeve including a first closed end and a second open end, and a connection sleeve adjacent the second open end, wherein the connection sleeve has a diameter dimension that is less than the diameter dimension of the first packaging sleeve;
- a second packaging sleeve having a longitudinal dimension and a diameter dimension, the second packaging sleeve having a first open end and a second closed end, and an accommodation region adjacent the first open end, wherein the accommodation region has a profile corresponding to a profile of the connection sleeve of the first packaging sleeve so that the connection sleeve of the first packaging sleeve is insertable in the accommodation region of the second packaging sleeve and, at times when the connection sleeve is inserted in the accommodation region, the first packing sleeve cooperates with the second packaging sleeve to establish a connection joint therebetween;
- and
- a sealing film that provides an air-tight seal over the connection joint, the sealing film having a starting edge in a second overlap edge, and a first overlap edge that covers the second overlap edge to define a coverage region that runs in the longitudinal dimension of the first and second packaging sleeves,
- wherein the sealing film comprises a heat-seal-capable sealing surface located on a side of the sealing film that faces a peripheral surface of the first and second packaging sleeves,
- wherein the first overlap edge of the sealing film conforms to the starting edge of the second overlap edge forming a sealing surface thereon that is approximately perpendicular to the peripheral surface of the multi-part packaging to provide an air-tight seal against the starting edge that runs in an axial direction, and
- wherein the sealing film further comprises a support film length that extends beyond the first overlap edge, the support film having a width substantially the same as the sealing film.
