Description
[0001] The present invention relates to a rigid hinged-lid
cigarette packet.
[0002] More specifically, the present invention relates to a rigid
hinged-lid cigarette packet of the type in the form of a
rectangular-section prism, and comprising a cup-shaped container, a
lid hinged to the container, and a collar in turn comprising a
first part projecting axially from an open end of the container and
connected in sliding manner to the lid, and a second part housed
inside the container; the container comprising a front wall, a rear
wall, and two lateral walls perpendicular to the front and rear
walls and connected to the front and rear walls along longitudinal
edges; each lateral wall being defined by superimposing a
respective first and a respective second appendix projecting
laterally from the front wall and rear wall respectively; and each
first appendix being connected to the front wall along a respective
longitudinal edge.
BACKGROUND OF THE INVENTION
[0003] Packets of the above type are normally formed from two flat
blanks, a first of which, when folded, forms the container and the
lid, and a second of which, when folded, forms the relative
collar.
[0004] On known cigarette packing machines, the last folding
operations performed on the first of said two blanks normally
comprise turning said front wall over into a position facing the
relative rear wall and onto said second part of the collar, and
squarely folding the relative first lateral appendixes.
[0005] Theoretically, following the above two folding operations,
the front and rear walls of the cup-shaped container should be
perfectly parallel and perfectly juxtaposed. In actual fact,
however, this is not always so, on account of the increasingly fast
operating speed of the packing machines employed.
SUMMARY OF THE INVENTION
[0006] It is an object of the present invention to perfect packets
of the above type, to ensure the above objective is safely
achieved.
[0007] According to the present invention, there is provided a
rigid hinged-lid cigarette packet in the form of a
rectangular-section prism, and comprising a cup-shaped container, a
lid hinged to said container, and a collar in turn comprising a
first part projecting axially from an open end of said container
and connected in sliding manner to said lid, and a second part
housed inside said container; the container comprising a front
wall, a rear wall, and two lateral walls perpendicular to the front
and rear walls and connected to the front and rear walls along
longitudinal edges; each lateral wall being defined by
superimposing a respective first and a respective second appendix
projecting laterally from the front wall and rear wall
respectively; each first appendix being connected to the front wall
along a respective longitudinal edge; and the packet being
characterized by said collar being provided, at said second part,
with at least two longitudinal slits defining respective tabs, each
of which has a free edge extending along a respective said
longitudinal edge.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] A number of nonlimiting embodiments of the present invention
will be described by way of example with reference to the
accompanying drawings, in which:
[0009] FIG. 1 shows a transparent view in perspective of a first
preferred embodiment of the packet according to the present
invention;
[0010] FIG. 2 shows the same view as in FIG. 1, of a second
preferred embodiment of the packet according to the present
invention.
DETAILED DESCRIPTION OF THE INVENTION
[0011] Number 1 in FIGS. 1 and 2 indicates as a whole a rigid
hinged-lid cigarette packet in the form of a rectangular-section
prism, and comprising a cup-shaped container 2, a cup-shaped lid 3
hinged to container 2 along a transverse hinge line 4, and a collar
5 in turn comprising a first part 6 projecting axially from an end
opening 7 of container 2 and connected in sliding manner to lid 3
when lid 3 is positioned closing opening 7, and a second part 8
housed inside container 2.
[0012] Container 2 comprises a front wall 9, a rear wall 10, and
two lateral walls 11 perpendicular to front wall 9 and rear wall 10
and connected to front wall 9 and rear wall 10 along longitudinal
edges 12 crosswise to hinge line 4, which extends at an end edge of
rear wall 10.
[0013] Each lateral wall 11 is defined by superimposing two
appendixes 13 and 14, of which the outer appendix 13 projects
laterally from front wall 9 and is connected to front wall 9 along
a relative longitudinal edge 12, and the inner appendix 14 projects
laterally from rear wall 10 and is connected to rear wall 10 along
a relative longitudinal edge 12.
[0014] Collar 5 comprises a front wall 15 substantially coplanar
with an inner surface of front wall 9; and two lateral strips 16,
each of which is substantially coplanar with an inner surface of a
relative lateral wall 11, and is connected to front wall 15 along a
relative longitudinal edge 17 extending along and inwards of a
relative longitudinal edge 12 of container 2.
[0015] A substantially C-shaped slit 18 is formed astride the
portion of each longitudinal edge 17 extending along part 6 of
collar 5, and comprises a straight central portion parallel to
relative longitudinal edge 17, and two end portions extending
across relative longitudinal edge 17. The two slits 18 are
positioned with their concavities facing and opposite, and define
respective tabs 20 coplanar with front wall 15, and whose free
edges 19--defined by the straight central portions of respective
slits 18--project laterally with respect to front wall 15 to
define, in known manner, a brake for the movement of lid 3 with
respect to container 2 and about hinge line 4.
[0016] In the FIG. 1 embodiment, a substantially C-shaped slit 21,
substantially identical with corresponding slit 18, is formed
astride the portion of each longitudinal edge 17 extending along
part 8 of collar 5, and comprises a straight central portion
parallel to relative longitudinal edge 17, and two end portions
extending across relative longitudinal edge 17. The two slits 21
are positioned with their concavities facing and opposite, and
define respective tabs 23 coplanar with front wall 15, and whose
free edges 22--defined by the straight central portions of
respective slits 21--project slightly and laterally with respect to
front wall 15 to define a locator by which to position front wall 9
with respect to rear wall 10.
[0017] When forming packet 1, and particularly when folding
appendixes 13 squarely, the free edges 22 of tabs 23 define a
relatively rigid support for appendixes 13 as they are folded, and
provide for automatically positioning front wall 9 with respect to
rear wall 10.
[0018] In the FIG. 2 embodiment, a substantially C-shaped slit 24
is formed astride the portion of each longitudinal edge 17
extending along part 8 of collar 5, and comprises a straight
central portion parallel to relative longitudinal edge 17, and two
end portions extending across relative longitudinal edge 17. The
two slits 24 define respective tabs 26, each of which is coplanar
with relative lateral strip 16, and whose free edge 25--defined by
the straight central portion of relative slit 24--projects slightly
and frontwards with respect to front wall 15.
[0019] When forming packet 1, and particularly when folding front
wall 9 squarely, the free edges 25 of tabs 26 define a relatively
rigid support for front wall 9, so as to ensure front wall 9 and
rear wall 10 are substantially perfectly parallel.
[0020] In a variation not shown, both a slit 21 and a slit 24 are
formed astride the portion of each longitudinal edge 17 extending
along part 8 of collar 5.
