Hinge lid pack, especially for cigarettes, with structural locking device

摘要

With hinge lid packs having a pack part 10 and a lid 11 hinged thereon, especially when they are equipped with round edges, it is difficult to ensure that the lid 11 precisely remains in the proper closing position. In order to guarantee an accurate closing position, a closing pressure is applied to the lid which is a result of frictional resistance or interlocking of a collar 23 in the lid 11. Collar 23 and lid 11 are interlocked by pushing webs 42, which define a recess 29 of the collar 23, into lateral openings 43 of an inner lid flap 39 so that the webs 42 move into a wedged position.
