Abstract

PROBLEM TO BE SOLVED: To provide a cigarette packet having a hinged lid which can be formed by a thin sheet material and can prevent a front panel of a container, i.e., the packet from being collapsed in a lateral direction during its normal use. SOLUTION: A typical rigid cigarette packet 1 is comprised of a container 2 having one opening end 3 and a lid 4 pivotally attached a rear edge of the container 2 and oscillated to expose or close the opening end 3. A frame member 14 is connected to a front panel 5 of the container 2 at a lower portion 17 of its central part 15 and an upper part 16 is protruded into the lid 4 through the opening end 3. The lower portion 17 of the frame member 14 at the central part 15 is formed with a plurality of reinforcing ribs 19, these reinforcing ribs 19 are extended across the lower portion 17 of the central part 15 and crossed with a major longitudinal axis 20 of the container 2. With such an arrangement as above, rigidity is applied to both central part 15 itself and the front panel 5 of the container 2 connected to the central part 15.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cigarette (cigarette) packet with a lid. In particular, the present invention relates to a box-shaped container having a main longitudinal axis and having a front panel arranged parallel to this axis and opening at one end, and a container hinged to this container to approach or separate from a position surrounding the open end. And a frame member having a first portion disposed inside the container at least partially in contact with the front panel and a second portion protruding from the container through an open end. And a cigarette packet comprising a substantially rigid assembly.

[0002]

BACKGROUND OF THE INVENTION Conventional cigarette packets of the type described above are generally formed from blanks, i.e., flat die-cuts made from cardboard and similar materials. The thickness of the blanks has been steadily decreasing over time for obvious savings, and in recent years it has become so thin that assembled packets cannot retain their stable shape during normal use. In particular, with the most recently manufactured packets, it has been found that the simple act of opening the lid often causes the front panel of the container to permanently bend outwards, making it difficult to close the lid thereafter.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a tobacco packet of the above type which can be formed from a particularly thin sheet material without the above-mentioned disadvantages.

[0004]

To achieve the above object, the present invention provides a box-shaped container having a main longitudinal axis and a front panel arranged parallel to the longitudinal axis and having an opening at one end. A lid that is hinged to this container and is movable with respect to the container in a direction toward or away from the position surrounding the opening end, and a first portion and an opening that are arranged inside the container in at least partial contact with the front panel A lidded tobacco packet comprising a frame member having a second portion projecting from the container through an edge, the front panel being crushed laterally inward or laterally outward during normal use A cigarette packet with a lid, characterized in that it comprises a plurality of transverse reinforcing elements for preventing

Further, the present invention provides the above tobacco packet, wherein the plurality of reinforcing elements are composed of a plurality of ribs. Further, the present invention provides the above tobacco packet, wherein the plurality of ribs are arranged so as to cross the longitudinal axis of the tobacco packet. Further, the present invention provides the above tobacco packet, wherein the plurality of ribs are linear.

Further, the present invention provides the above-mentioned tobacco packet, wherein the plurality of ribs are lid-shaped tobacco packets which are ridges coined on a sheet material forming a part of the tobacco packet. The invention further provides a tobacco packet according to the above, wherein a plurality of ribs are formed in a central portion of a frame member arranged substantially flush with a front panel of the container.

Further, the present invention provides the above-mentioned cigarette packet, wherein a plurality of ribs are formed in a lower portion of a central portion of the frame member, and the lid-attached cigarette packet is arranged inside the container by contacting an inner surface of the front panel. provide.

DETAILED DESCRIPTION OF THE INVENTION Referring to FIG. 1, a solid cigarette packet 1 capable of containing a group of cigarettes (not shown).
Are arranged on the upper side, which also has a box-like appearance, on the lower side, which is essentially formed as a box with an upper open end 3, and which is hinged to the vessel 2, Upper open end 3
And a lid 4 that is pivotable between an open position that exposes the open end and a closed position that covers the open end 3. The container 2 includes a front panel 5 and a rear panel 6 that are arranged parallel to each other, and two lateral panels 7 that are parallel to each other and orthogonal to the front panel 5 and the rear panel 6, a front panel 5, and a rear panel 5. A panel 6 and a lower end panel 8 arranged orthogonally to both lateral panels 7 are provided.

The lid 4 is provided with a front panel 9 and a rear panel 10 which are arranged parallel to each other and oppositely to each other, and two horizontal panels 1 which are arranged parallel to each other and orthogonal to the front panel 9 and the rear panel 10.
1, a front panel 9, a rear panel 10, and both lateral panels 11
And an end panel 12 arranged orthogonally to each other. In particular, the upper and lower edges of the rear panel 6 of the container and the rear panel 10 of the lid, respectively, are permanently and foldably interconnected along the fold line forming the hinge 13. The lid 4 is the hinge part 1
With respect to 3, it is pivotable between the open and closed positions described above.

The packet 1 further comprises a U-shaped frame member 14 which partially projects from the open end 3 of the container. The frame member 14 comprises a central part 15, which is formed by an upper part 16 extending upward from the rear side of the front panel 5 of the container and a lower part 17 rigidly connected to the inner surface of the front panel 5. It The frame member 14 further comprises two lateral parts 18. Each lateral portion 18 is fixed to the inner surface of the corresponding lateral panel 7 and projects beyond the open end 3 into the lid 4.

As shown in FIG. 2, the frame member 14
Has a plurality of reinforcing ribs 19. Those reinforcing ribs 19
Extend across the lower part 17 of the central part 15 and
Intersects the major longitudinal axis 20 of. Thereby, the central part 15
Rigidity is imparted to both itself and the front panel 5 of the container 2 connected thereto. The reinforcing rib 19 is formed in a linear shape in the illustrated embodiment, and has the shape of a ridge imprinted on the sheet material forming the frame member 14. Of course reinforcement rib 1
9 may have a shape other than the linear shape shown in the drawing, such as a sine curve, and the container 2 is not the frame member 14.
The front panel 5 can also be directly coined.

In another embodiment not shown, the reinforcing rib 1
It is also possible to omit 9 and instead install a reinforcing member that is firmly connected to the inner surface of the front panel 5. For example, a stiffening member of this kind may consist of a tongue or flap (not shown) extending from the upper edge of the front panel 5 and folded flat against the inner front surface of the container. The flap may include a plurality of ribs similar to the reinforcing ribs 19 shown.
