Problems solved by technology

In general, however, these two types of cassettes require specific machines to be manufactured with relatively high precision, such as those disclosed in European patent documents EP-A-0205894 and EP-A-0200087, but these The machine works relatively slowly and is strictly a dedicated machine, that is, it cannot be used for the manufacture of other packs than the two types mentioned above
[0009] The above factors make the cost of these two packaging boxes very high
[0010] Furthermore, besides the high price, boxes with rounded edges present other disadvantages: as a result of the difficulty of aligning the two circular profiles with each other, usually the lids of the boxes do not align very precisely with their box-shaped parts. close together; and at the rounded corners of the upper top and lower bottom surfaces, the outer transparent wrapping material cannot coincide with the outer surface of the box. As a result, a rigid convex shape is formed at both ends of these rounded corners. sharp corners, which are not only unsightly, but also cause hard scratches to fabric fibers and similar objects with which they come into contact

Embodiment Construction

[0023] Numeral 1 in Fig. 1 to Fig. 5 indicates a whole cigarette case containing a group of cigarettes 2, wherein the cigarettes are arranged in layers. In the embodiment shown, the cigarettes are three-ply, wherein the middle ply has fewer cigarettes 2 than the outer two plies.

[0024] The cigarette case 1 comprises a cup-shaped lower bottom container 3, which is open at its upper end 4; Rotate between to open and close the upper end 4 respectively.

[0025] When the top cover 5 is closed, the cigarette case 1 is substantially a rectangular parallelepiped, which is surrounded by a front wall 6 and a rear wall 7, two sides 8, a top wall 10 and a bottom wall 11, wherein: The front wall 6 and the rear wall 7 are basically kept parallel to each other and bent outward; the two sides 8 are parallel to each other and are generally perpendicular to the side walls 6 and 7, and at the corresponding sharp edges 9 and the walls 6 and 7 connected together; the top wall 10 and a bottom ...

Abstract

A rigid packet with a hinged lid (5) for cigarettes has a front wall (6) and a rear wall (7), each curving outwards and having a respective flat central portion (12) and two curved, preweakened lateral bands (17) connecting the relative flat central portion (12) to two flat lateral walls (8) of the packet at respective sharp edges (9).

Description

technical field [0001] The invention relates to a clamshell hard shell packaging box. [0002] More particularly, the present invention relates to a hinge-lid rigid box made of flat paperboard or similar material with pre-folded weakening grooves. Background technique [0003] A particularly suitable application of the invention is in the manufacture of cigarette packs, to which particular reference is made in the following description which is only illustrative. [0004] Hinged-lid hard-shell cigarette packs are generally of rectangular cross-sectional parallelepipedic construction comprising a front wall and a rear wall joined together at each longitudinal edge by two side walls. [0005] Given their non-removable shape and their tendency to be so rigid as to damage the fibers of clothing or other objects in contact with them, rigid boxes of the parallelepipedic structure with rectangular cross-sections as described above have several drawbacks. [0006] Another disadvan...
