Description

  The present invention relates to a cigarette box with a hinged lid and an associated packaging method.

  A rigid hinged lid cigarette box includes an inner package that encloses a group of cigarettes and a rigid outer package that houses the inner package. The outer package includes a cup-shaped container having an open top and a lid hingedly connected to the container to rotate between an open position and a closed position that open and close the open top.

  Most commercial cigarette box lids have a front wall, a top wall perpendicular to the front wall, a rear wall opposite the front wall and parallel to the front wall, and two opposing walls perpendicular to the other wall. Parallel side walls. Usually, the upper and rear walls of the lid are one layer, and only a limited portion of the front wall of the lid is double-layered by folding the reinforcing flap and gluing it to the inner surface. However, in some cases, the top and rear walls must also be reinforced to reinforce the entire lid and reduce deformation caused by repeated opening and closing of the lid.

  In order to reinforce the top and back walls of the lid, the walls are each made of two layers that are overlapped and preferably glued. Thus, for the front wall, top wall and back wall of the lid, the blank from which the outer package is produced has an inner panel and an outer panel, the panels being stacked, preferably Are glued together. In a preferred embodiment, before applying the blank to the inner package, i.e. upstream of the packaging unit where the blank is folded around the inner package, the inner and outer panels of the front, top and rear walls of the lid are , Superimposed and preferably glued. However, it has been found that the inevitable rebound force in the blank causes relative movement between the laminated and glued inner and outer panels of the front, top and rear walls of the lid. As a result, in the actual container, the inner panel and the outer panel do not match properly (the adhesive between the inner panel and the outer panel is cured to some extent in order to exhibit sufficient grasping power. Note that it takes time).

  Therefore, mechanical means for applying pressure to the panels in order to keep the inner and outer panels of the lid front wall, top wall, and rear wall in place after the inner and outer panels are overlaid. Needed. However, this type of means is complicated to manufacture and greatly increases the cost of the packaging machine.

  It is an object of the present invention to provide a hinged lid cigarette box and associated packaging method that is designed to obviate the above drawbacks and at the same time is cheap and easy to implement.

  In accordance with the present invention, there is provided a hinged lid cigarette box and associated packaging method as claimed in the claims.

  In the variant of FIG. 7, the mechanical holder 21 comprises a rotating tab 30 that is arranged side by side on the holding tab 22 and separated from the holding tab 22 by a fold line 23. The rotating tab 30 is formed by a central portion of the outer panel 9 ′ separated from the rest of the outer panel 9 ′ by a U-shaped through cut and by a fold line 23 connecting the ends of the U-shaped through cut. It plays the role of rotating 22. When rotated (pressed) about the fold line 23, the rotating tab 30 causes a similar rotation of the holding tab 22 about the fold line 23.

  4-7, the lower free end of the inner panel 9 "is inserted below the holding tab 22 of the holding body 21. In the embodiment of Figs. 8-10, the inner panel 9 is inserted. The lower free end of "" is positioned so as to contact the upper free end of the holding tab 22 of the holding body 21. That is, the two free ends of the inner panel 9 "and the retaining tab 22 are coplanar and are positioned to face and abut each other, and the retaining tab 22 has the inner panel 9" on the outer side. It can be lifted against the outer panel 9 'before or after being overlaid on the panel 9'.

  In the illustrated embodiment, the holding body 21 of the outer panel 9 ′ has only one holding tab 22. In a completely equivalent embodiment (not shown), the holding body 21 of the outer panel 9 ′ has two (or three) holding tabs 22 in parallel.

  In another embodiment (not shown), the cigarette box 1 is of a slide open type and comprises two partially separable containers, one inserted inside the other. The container 2 forms an inner container, is accommodated inside the outer container, is in a closed state in which the container 2 is inserted into the outer container, and the container 2 is partially pulled out of the outer container. Slide between open states. The lid 5 of the container 2 has a connection tab connected to the lid 5 at one end and connected to the outer container at the opposite end, and “automatically” when the container 2 slides relative to the outer container. The lid 5 can be rotated (ie, without the user needing to touch the lid 5). In other words, when the container 2 slides relative to the outer container, the connecting tab mechanically connects the wall of the lid 5 to the wall of the outer container so that the outer container moves from the closed position to the open position or vice versa. Since the lid 5 is pushed automatically (ie, the user does not have to touch the lid), the user only applies enough pressure to slide the container 2 against the outer container without having to touch the lid 5 Now the lid rotates "automatically".

  In another embodiment (not shown), the lid 5 does not have the front wall 14 (thus the blank 24 does not have the panels 14 'and 14 "). This embodiment is combined with the slide open mold described above. It is preferred (but not necessarily combined).

  In another variant, the container 2 can be accommodated in an outer box which forms part of the cigarette box 1 as well.

  The cigarette box 1 described above has a number of advantages.

  First, in the cigarette box 1 described above, the inner panel 9 ″ is held in the correct position by the holder 21 of the outer panel 9 ′, so that the inner panels 9 ″, 15 ″, 13 ″ and 14 ″ are After being glued to the outer panels 9 ', 15', 13 'and 14', after being overlaid on the corresponding outer panels 9 ', 15', 13 'and 14' The important thing is that the inner panels 9 ", 15", 13 "and 14" are connected and prevented from moving significantly with respect to each other, so that only the inner panel 9 " It only needs to be mechanically connected to the outer panel 9 ′ by 21.

  Secondly, the cigarette box 1 described above is different from the similar known cigarette box 1 only in that the holding body 21 is present, so that it can be easily manufactured at low cost. The holding body can be easily manufactured on the outer panel 9 'by a simple mechanical operation (ie by forming a U-shaped through cut and fold line 23) that is not different from the operation that the blank 24 has already undergone.

  Finally, the cigarette box 1 described above can be manufactured inexpensively and easily because the holding tab 22 can be folded when the blank 24 is folded by a few simple operations on the outer panel 9 '.
