Description

Packet for tobacco products {PACKET FOR TOBACCO PRODUCTS}

The present invention relates to a packet for tobacco products.

Hereinafter, in this specification, specifically and as an example, a cigarette hard packet is referred to, but the scope of the present invention is not limited thereby.

Prior art cigarette hard packets are obtained by folding a flat paperboard blank provided with one or more pre-fragmented fold lines, a container opening at one end, a lid hinged to one end edge of the container, And a collar fixed inside the container.

Generally, the conventional hard packet extends along the main longitudinal axis and includes a front wall portion, a rear wall portion, two side wall portions, an upper wall and a lower wall. The front wall portion and the rear wall portion are connected to two side wall portions by respective (sharp or round or beveled) edges parallel to the longitudinal axis of the main extension.

In order to make the conventional hard packet more attractive from an aesthetic point of view, the above-mentioned edge connecting the packet, specifically, the front wall portion and the rear wall portion to each side wall portion has been modified.

However, there is a concern that the deformation of the parallel edges mentioned above results in deformation of the outer circumference of the packet along the section transverse to the longitudinal axis of the main extension, and causes various defects when packaging the packet.

The object of the present invention is to provide a cigarette packet capable of overcoming the above mentioned drawbacks, i.e. the related longitudinal direction, parallel to the main extension axis, while the outer periphery of the packet remains the same as the perimeter of the conventional packet. It is to provide a packet forming a specific shape of the corners.

Accordingly, the present invention provides a cigarette packet including the features set out in claim 1.

More specifically, reference numerals "8" and "9" denote the connecting edges of the side wall portion 4 and the side wall portion 5 and the front wall portion 2, respectively, and reference numerals "10" and "11" are respectively. The connecting edge of the side wall part 4 and the side wall part 5 and the rear wall part 3 is shown.

The packet 1 includes a container 12 for accommodating a group of cigarettes 13 and a lid 14 hinged to the container 12 along the hinge line 15.

The hinge line 15 is located on the rear wall 3 and rotates the lid 14 around the hinge line 15 to move the packet 1 from the closed position to the open position and vice versa. .

The collar 16 is fixed inside the container 12 at least at the front wall 2.

Preferably, the collar 16 is secured inside the container 12 at the front wall 2 and at the side walls 4 and 5.

Different embodiments of the packet 1 shown in Figs. 1 to 8 have a common technical feature, which is shown sequentially by the codes introduced below and below.

More specifically, the packet 1 has at least one edge face 17 having a variable transverse dimension along a direction parallel to the longitudinal axis A, along each of the connecting edges 8, 9, 10, 11 It includes.

Each edge face 17 emanates from at least one first shared vertex 19, provided along each connecting edge 8, 9, 10 and 11, and the same connecting edge 8, 9, 10 and According to 11) it is also defined by the associated side wall edge 18, which extends to converge at at least one second shared vertex 20, also provided.

Adjacent to the front wall portion 2 and the two side wall portions 4 and 5, the side wall edge 18 of the edge face 17 is a front wall portion 2 and two side wall portions 4 and 5, respectively. It extends along at least part of.
