Problems solved by technology
[0010] However, in standard packaging machines, placing and folding the collar around the bundle of cigarettes prior to wrapping the inner wrapping sheet around the bundle is very complicated
So, in order to achieve this inner packaging, it is necessary to make improvements that may reduce the overall productivity

Embodiment Construction
[0023] refer to Figure 13 , numeral 1 shows a complete inner package for a rigid pack of cigarettes, preferably made of cardboard or cardboard, and shaped as a cup with a reclosable lid.
[0024] Said inner pack 1 encloses a bundle of cigarettes 10 having a parallelepiped shape and said inner pack 1 has an opening for extracting the cigarettes at the front and at the top, defined by a weakening line 2 .
[0025] When the inner package 1 surrounds the bundle of cigarettes 10, the inner package 1 has a cuboid shape, which has a top wall 3 and a bottom wall 4 parallel and opposite to each other, and two main sides parallel and opposite to each other. Walls 5 and 6, and a secondary side wall 7 parallel to and opposite to each other. In particular, said main side wall 5 defines a front wall of said inner packaging 1 and the other main side wall 6 defines a rear wall of said inner packaging 1 . Four longitudinal edges are defined between said secondary side wall 7, front wall 5 a...

A method for manufacturing a sealed package (1) for a bundle of cigarettes (10), comprising: providing a rigid container (20) suitable for a bundle of cigarettes (10) to be assembled therein; inserting a reinforcing component (30) Within a rigid container (20); a bundle of cigarettes is inserted into the rigid container (20) to be surrounded by a reinforcing component (30); a packaging sheet (11) is provided with a line of weakening (2) to form a pair of the bundle The entrance of the cigarette (10); fold the packaging sheet (11) into a U shape on the rigid container (20) to have two parallel wings on the rigid container (20); from the rigid container (20) Take a bunch of cigarettes (10) with the reinforcing component (3) and drag the packaging sheet (11) until it contacts the bunch of cigarettes (10) and the reinforcing component (3) without the rigid container (20) inserted therein; by The transverse fins (9) are produced to perform a first sealing step to form a connection of two wings of the packaging sheet along a transverse edge (14) of a bundle of cigarettes (10). When the transverse fins (9) are vertically aligned with the bundle of cigarettes When the edges of the bottom wall of (10) are arranged, the transverse fins (9) are welded; and a final sealing step is performed on the open side of the packaging sheet (11) to form a sealed package (1).
Description
technical field [0001] The present invention relates to a method for producing a sealed pack of a bundle of cigarettes. [0002] The invention also relates to associated equipment for carrying out said method. [0003] The invention is particularly applicable to the tobacco industry. Background technique [0004] Traditionally, cigarettes are packed in rigid or semi-rigid containers, which are wrapped inside an inner wrapper, usually made of aluminum foil. [0005] Even if said inner packaging is widely used, this form of inner packaging is a compromise solution between the manufacturing cost and the necessity not to change the aroma quality of cigarette tobacco. [0006] In fact, in order to better preserve the quality perception of the product, it is certainly preferable to realize a hermetically sealed inner package produced starting from a sheet of thermoplastic film welded along the periphery of the bundle of cigarettes contained therein. [0007] In order to maintai...
