Abstract
Description
- The present invention relates to a container for tobacco articles.
- More specifically, the present invention relates to a container for tobacco articles, e.g. a cigarette packet or carton, of the type formed by folding sheet material, normally a blank, and comprising at least one double-layer wall defined by an inner portion and an outer portion of sheet material superimposed on each other, at least part of the inner portion being covered by a corresponding part of the outer portion.
- The present invention is particularly advantageous for producing hinged-lid packets of cigarettes, to which the following description refers purely by way of example.
- In the tobacco industry, hinged-lid packets of cigarettes, i.e. packets comprising a body and a lid hinged to each other along a hinge line, are known to be produced by folding a flat, substantially rectangular blank, on which two preformed longitudinal fold lines or strips, parallel to each other and to a longitudinal axis of the blank, define a central body divided by a number of preformed transverse fold lines and by said hinge line into a succession of panels normally comprising a first front panel of the body, a second bottom panel of the body, a third rear panel of the body, a fourth rear panel of the lid connected to the third panel along said hinge line, a fifth top panel of the lid, a sixth front panel of the lid, and a seventh reinforcing panel of the sixth panel.
- Outwards of the central body, the preformed longitudinal fold lines or strips define two first flaps connected to respective longitudinal edges of the first panel; two second flaps connected to respective longitudinal edges of the third panel; two third flaps connected to respective longitudinal edges of the fourth panel; and two fourth flaps connected to respective longitudinal edges of the sixth panel.
- When folding the blank, each of the above flaps is folded squarely with respect to the relative panel and superimposed on another flap to form a relative portion of a lateral wall of the packet. More specifically, each first flap is placed on and gummed to the outer surface of a corresponding second flap, and each fourth flap is placed on and gummed to the outer surface of a corresponding third flap, to form, on the packet, two opposite lateral walls, on each of which the free edges of the outer flaps are visible.
- The fact that the free edges are visible has both aesthetic and functional drawbacks. That is, the free edges, on the one hand, are normally the natural colour of the cardboard from which the blank is made, as opposed to the same colour/s as the adjacent outer surface of the packet, and, on the other, are rough, so that the packet is apt to catch, in use, on surrounding materials, and any transparent overwrapping material is prevented from adhering perfectly to the outer surface of the packet.
- US4526317 discloses a parallelepiped container for cigarettes formed by bending and folding a single blank of a suitably cut sheet of paperboard, cardboard or other stiff, resilient and foldable material. The container carries a boxlike lid hinged along its rear wall; the inner sides of the lid carry lid guide panels, spaced from the lid sides, with the side portions of certain corner posts slidably positioned between the lid sides and the lid guide panels. In a modification, the corner posts and the upper portion of the front of the main body portion of the container are debossed. US 4 526 317 discloses all features of the preambles of the independent claims.
- US5197935 discloses a liquids package having side walls as well as upper and lower walls serving as top and bottom respectively, a side wall and the top having a sealing seam extending along edges of adjacent wall panels; so that the package may have a smooth outer surface in the region of sealing seams, without the formation of synthetic plastics beads or the like, the outer surface of the two wall panels which are connected to each other by the sealing seam are disposed to merge steadily into each other via the gap along at least one end face of an edge which belongs to the relevant wall panel so that the other surfaces are flush in cross-section, and in that the sealing seam is masked on the inside of the package by a synthetic plastics bead.
- It is an object of the present invention to provide a container for tobacco articles, designed to eliminate the aforementioned drawbacks.
- According to the present invention, there is provided a container for tobacco articles, as claimed in Claim 1 and, preferably, in any one of the following Claims depending directly and/or indirectly on Claim 1.
- The present invention also relates to a method of producing the container for tobacco articles as defined above. According to the present invention, there is provided a method of producing a container for tobacco articles, as claimed in
Claim 6 and, preferably, in any one of the following Claims depending directly and/or indirectly onClaim 6. - A number of non-limiting embodiments of the present invention will be described by way of example with reference to the accompanying drawings, in which:
