JP4105546B2 - Pack with rigid hinged lid for tobacco products - Google Patents

Abstract

A rigid pack with a hinged lid for tobacco products appears as a container (3) presenting an open top (4) surrounded by a free edge (3a), and a lid (5) hinged to the container along a crease line (6) and presenting a free bottom edge (5a) . When the lid (5) occupies the closed position, the two free edges (3a, 5a) meet along a closure line (15) of which at least one portion describes a path deviating at least in part from a path parallel to the hinge line (6) and exhibiting a highlighted area (21) along at least part of its length. The highlighted area (21) serves to accentuate the closure line (15) and can be printed, if intended simply to make the line more clearly visible, or alternatively, obtained by embossing or by applying a layer of material having a high coefficient of friction with the additional end in view of providing a roughened surface which besides accentuating the closure line (15) also facilitates the operation of opening the lid (5).

Description

[0001]
[Technical field]
The present invention relates to a rigid pack having a hinged lid for tobacco products.
[0002]
As used herein, the term “pack” may be understood to mean a carton for containing multiple packets of cigarettes, or generally a single packet containing a group of cigarettes or tobacco products. .
[0003]
[Background technology]
Generally, a rigid packet of the above type is machined from a flat die-cut blank that has been creased and hinged at the rear edge of the container so that it can rotate around the hinge line to close the open end of the container. It includes a lid that is stopped and a reinforced frame that is partially installed inside the container. The frame is fixed to the front surface of the container and the two flank surfaces and functions as a stabilizing element that acts to hold the lid in place when the pack is closed.
[0004]
Traditionally, when this type of pack is closed, the lower free edge of the lid and the upper free edge of the container contact each other along the closing line, and in particular, each edge portion that is aligned at the front of the pack is hinged. Are provided in parallel.
[0005]
The prior art also includes packs in which two free edges, or at least the portion of the edge that coincides with the portion of the closure line that occupies the front of the pack, is distorted and not parallel to the hinge line.
[0006]
The latter solution is empirically considered to enable effective closure of the lid by increasing the contact area between the inside of the lid and the reinforcing frame.
[0007]
In addition, this solution is confusing for consumers accustomed to handling traditional types of packets to position the edge of the lid with the first touch and when opening the lid, especially when breaking new packets A difficulty has been observed. This is because the contact surface between the frame and the lid is large, and as a result, the packet may be damaged.
[0008]
The object of the present invention is to eliminate the above-mentioned drawbacks.
[0009]
[Disclosure of the Invention]
The object includes a container having an opening forming an upper free edge, and a lid hinged to the container along a hinge line and having a lower edge, wherein the lower edge is provided by the container. Forming a closure line when in a closed position in contact with the upper free edge, at least a portion of the closure line coinciding with at least the front surface of the pack extends along a direction inclined with respect to the hinge line; In a pack with a rigid hinge lid for a tobacco product exhibiting a substantially parallelepiped appearance, wherein a highlight region that acts to emphasize the closing line is formed along the closing line, wherein the highlight region is the closing line. Extending from one flank surface of the pack to the other flank surface through the front surface of the pack along the entire length of the pack to form a closure line for the lower edge of the lid, and the highlight Band is characterized in that material layer of high coefficient of friction forms a granted rough surface is accomplished by the pack.
[0010]
The present invention will now be described in detail by way of example with reference to the accompanying drawings.
[0011]
Referring to Figures 1 to 10 of the accompanying drawings, 1 generally indicates a pack of tobacco products, in this particular example, embodied as a rigid packet 2 for containing a group of cigarettes (not shown), It includes a cup-shaped container 3 having an open upper end 4 and a cup-shaped lid 5 mounted thereon, the lid 5 being in the open position shown in FIGS. 2, 4, 6, 8 and 10, and FIGS. Connected to the container 3 along the hinge line 6 is rotatable between a closed position in which the open upper end 4 of the container shown in 5, 7 and 9 is closed.
[0012]
The container 3 has a lower end surface 7, a front surface 8, a rear surface 9 and two flank surfaces 10. The upper free edges 8a and 10a of the front face 8 and the flank face 10 combine to form the upper free edge 3a of the container and thus coincide with the open upper end 4 towards the lid 5.
Similarly, the lid 5 has a front surface 11, a rear surface 12, two flank surfaces 13, and an upper end surface 14.
[0013]
The front face 8 of the container 3 and the front face 11 of the lid 5 form the front face 2 a of the packet 2, while the flank face 10 of the container and the flank face 13 of the lid form the flank face 2 b of the packet 2.
[0014]
The front face 11 and the flank face 13 of the lid combine to form a lower edge 5a of the lid 5 and have free edges 11a and 13a that coincide with the open lower end, respectively, said open lower end when the lid 5 is in the closed position To the container 3.
[0015]
In the closed position, the upper free edge 3a and the lower edge 5a of the matching container 3 and lid 5, respectively, form a closed line on the packet 2.
[0016]
The single packet 2 contains an inner package 16 enclosing a group of cigarettes (not shown), and has a reinforcing frame 17 interposed between the hard material of the packet 2 and the inner package 16, and the reinforcing frame 17 is a container. 3 and a portion 17a located inside the container 3 and a portion 17b protruding from the container through the open upper end 4.
[0017]
More precisely, the reinforced frame 17 has a breast piece 18 partly fixed inside the front face 8 of the container 3 and two side pieces partly fixed inside the flank face 10 of the container 3. 19
[0018]
The breast piece 18 of the frame 17 terminates at the top at a “U” shaped edge 20 having a concave contour line towards the lid 5.
[0019]
In the example of FIGS. 1 to 10 showing the packet 2 in the closed position, i.e. the lower free edge 5a of the lid 5 engages the upper free edge 3a of the container 3 and the two matching edges join to form the closing line 15. The closed line 15 forms a path deviated from a path parallel to the hinge line 6.
[0020]
In the case of FIG. 1, more precisely, the closing line 15 describes a passage across the front face 2a, the concave ridge line towards the lower end face 7 near each flank surface 2b, and two concave ridge lines on each flank face 2b. The arcuate end faces the upper end surface 14.
[0021]
In the case of FIG. 3, the closing line 15 describes an arcuate passage having a concave ridge line toward the upper end surface 14 on the front surface 2a and the flank surface 2b.
[0022]
Finally, in the example of FIGS. 5, 7 and 9, the closing line 15 crosses both the front surface 2a and the flank surface 2b as shown in FIG. 5 or across the front surface 2a as shown in FIGS. Draw a wavy passage that extends.
[0023]
As can be seen, the closing line 15 shown in the accompanying drawings is merely exemplary, and in practice at least a portion of the closing line 15 is from a passage parallel to the hinge line 6 to which the lid 5 and the container 3 are connected. Draw a predetermined path deflected.
[0024]
According to the invention, the single packet 2 has a highlight area 21 which occupies at least a part of the closing line 15 and highlights the closing line 15.
[0025]
In the examples of FIGS. 1, 2, 5 and 6, the highlight area 21 extends along the entire length of the closing line 15, while in the examples of FIGS. 3, 4, 7, 8, 9 and 10, the highlight area 21 Extends along only part of the closing line 15.
[0026]
The highlight area 21 may be formed in the lid 6 in all illustrated embodiments and printed as shown in the examples of FIGS. Alternatively, the highlight region 21 may be formed by reeding or embossing, as shown in the examples of FIGS. Finally, as shown in the examples of FIGS. 7 to 10, the highlight region 21 can be formed by adding a layer 22 of a material having a high friction coefficient such as paint or lacquer.
[0027]
For this purpose, in the case of the illustrations of FIGS. 5 and 6 and FIGS. 7, 8, 9 and 10, the respective highlight areas 21 can more easily recognize the closing line 15 and open the lid 5 from the container 3. It is important to observe that it provides a rough surface for ease of operation.
[0028]
Furthermore, it should be noted that the highlight areas 21 obtained by embossing in the examples of FIGS. 5 and 6 or by application of materials in the examples of FIGS. In addition, it can be formed.
[0029]
As shown in the examples of FIGS. 11 and 12, all the packets shown in FIGS. 1 to 10 are formed to have longitudinally inclined corner edges 23 (FIG. 11) or arcuate corner edges 24 (FIG. 12). it can.
