DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge lid pack, and more particularly to a hinge lid pack suitable as a packaging pack for smoking articles such as filter cigarettes and a blank thereof.

[0002]

2. Description of the Related Art A hinge lid pack for an internal body of a filter cigarette includes a box-shaped pack body, an inner frame protruding from an opening of the pack body, and
When closing the lid, cover the protrusion of the inner frame,
And a box-shaped lid that is in close contact with the opening of the pack body.

[0003]

By the way, this kind of hinge lid pack is such that when the lid is closed, the opening of the pack body and the opening edge of the lid simply coincide with each other on the front side. It has a uniform design and lacks the appeal of promoting consumer willingness to purchase. The present invention has been made on the basis of the above circumstances, and an object of the present invention is to provide a hinge lid pack and a blank thereof that have a simple configuration and can enhance the appeal to consumers.

[0004]

According to a hinge lid pack which achieves the above object, a front edge of the pack opening in the pack body is depressed in a triangular shape, and conversely, a front side of the lid opening edge. The parts are projected in a triangular shape. With this configuration, when the lid is closed, the front part of the lid opening edge matches the concave front edge of the pack opening not in a straight line but with each other so as to mesh with each other.

[0005] The meshing state of the pack opening and the lid makes the appearance of the hinge lid pack of the present invention unique even when the lid is opened as well as when the lid is closed, as compared with a normal hinge lid back. And it has excellent appeal to consumers. The left and right side walls of the lid include an outer side wall and an inner side wall, and the inner side wall is positioned so as to be recessed from a corresponding portion of the lid opening edge. With this configuration, even when the front edge of the inner frame or the above-described inner package and the ceiling wall of the lid interfere with each other during the folding forming of the hinge lid pack, the inner side wall does not protrude from the outer side wall. The beauty of the pack is maintained.

[0006] In the case of the above-mentioned hinge lid pack, it is preferable that the front edge of the inner frame is also depressed in a triangular shape similar to the front edge of the pack opening. According to such a configuration, at the time of opening the lid, the V-shaped band formed between the front edge of the opening in the pack body and the front edge of the inner frame has a triangular shape at the front side of the lid opening edge. The shape conforms to the shape, and is aesthetically superior.

The present invention also provides a blank for forming the above-mentioned hinge lid pack (claim 4).
The blank includes a main blank for forming the pack body and the lid according to claim 1 or 2 described above, and a sub-blank for forming the inner frame according to claim 1 or 3.

Are engaged with the front edge 4a of the opening 4 so as to mesh with each other. FIG. 2 shows the pack body 2 and the lid 12 described above.
Are shown for forming the main blank. These main blanks are sections 16, 18, 20 for forming the front wall 8, the bottom wall and the rear wall of the pack body 2, respectively.
The sections 16, 18, and 20 are arranged in a line via a fold line.

Outer side flaps 22 forming left and right outer walls of the pack body 2 are connected to both sides of the section 16 through folding lines, and inner side flaps 24 corresponding to the outer side flaps 22 are provided on both sides of the section 20. Are connected via a folding line. Each inner side flap 24 has a section 18
The inner bottom flaps 26 for forming the inner bottom wall so as to be located on both sides of the inner bottom wall are connected to each other through folding lines.

Further, section 20 includes section 18
A lid portion for forming the lid 12 on the opposite side is connected via a double-dashed fold line serving as the self-hinge 10, and this lid portion is connected from the section 20 side to the rear wall of the lid 12 and the outside. It has sections 28, 30, and 32 which are the top wall and the front wall.
30 and 32 are also connected in a line via a folding line.

On both sides of the section 28, inner side flaps 34 for forming left and right inner walls of the lid 12 are formed.
Are connected via folding lines, and outer side flaps 36 for forming left and right outer walls of the lid 12 are connected to both sides of the section 32 via folding lines, respectively. Further, inner top flaps 38 serving as inner top walls of the lid 12 are connected to the inner side flaps 34 via folding lines so as to be located on both sides of the section 30.

As is apparent from FIG. 2, the section 16 serving as the front wall 8 of the pack body 2 has an edge opposite to the section 18, that is, the front edge 4a of the opening 4 in the pack body 2.
Is depressed in a triangular shape. On the other hand, the section 32 serving as the front wall of the lid 12 has a section 30.
The inner front flaps 40 are respectively connected to the left and right sides via fold lines on the opposite side to the fold lines, and the fold lines 40a have the same triangular bent shape coinciding with the edge 16a. The folding line 40a is a portion that forms the front portion 12a of the lid opening edge described above.

Further, gaps 42 are secured between the inner side flaps 24 as the inner side walls of the pack body 2 and the inner side flaps 34 as the inner side walls of the lid 12, respectively. 24 is formed by cutting the edge of the main blank, and has a triangular shape that gradually expands toward the side edge of the main blank as a whole.

The outer and inner side flaps 22 and 24 serving as outer and inner side walls of the pack body 2 and the outer side flap 2 serving as an outer side wall of the lid 12 are provided.

It is inclined symmetrically with respect to the longitudinal axis.

FIG. 3 shows a sub-blank for forming the above-mentioned inner frame 6, which has a substantially rectangular shape, and a section 44 having the same width as the inner portion of the filter cigarette FS at the center thereof. It includes a pair of side flaps 46 connected to both sides of the section 44 via fold lines. One edge 44a of the section 44 is triangularly recessed to form the above-described front edge 6a of the inner frame 6, and a side flap 46 connected to the concave edge 44a.
Is the side edge 6b described above. In contrast,
The other edge 44c of the section 44 protrudes in a triangular shape, and the triangular shapes of the edges 44a and 44c are congruent with each other.

According to the above-described sub-blank for the inner frame 6, for example, as shown in FIG. 4, on both sides of the web material 48 for the sub-blank, first, folding lines 50 shown by broken lines are respectively formed, After that, the web material 48 is cut and separated along a cutting line 52 indicated by a one-dot chain line, so that a sub blank can be obtained without wasting the material of the web material 48.

The above-mentioned main blank is folded in the same folding procedure as the main blank of the ordinary hinge lid pack, and the sub-blank is also folded in the same manner as the sub-blank of the ordinary hinge lid pack. The inner flap 6 is folded around the inner package body. Then, the inner package provided with the inner flap 6 is combined with the main blank during the folding process of the main blank, whereby a hinge lid pack (see FIG. 1) containing the inner package is manufactured.

FIG. 5 shows a folding process of the main blank. In this folding process, the inner frame 6 is folded after the inner side flaps 24, 34 on the left and right sides of the main blank are folded up from their folding lines. The provided inner package (see dash-dot line) is placed on the section 20 of the main bracket, and the inner bottom flap 26 of the inner side flap 24 is folded from its fold line onto the bottom surface of the inner package, and The inner top flap 38 of the flap 34 is folded from the folding line onto the top surface of the inner package.

Thereafter, the folding of the other sections and flaps is sequentially performed. At this time, the folding line of the section 30 must be accurately positioned at the top surface of the inner package. However, if the positioning of the inner frame on the section 20 or the mounting position of the inner frame 6 with respect to the inner frame occurs, the folding line of the section 30 may shift into the inner frame or the inner frame 6. In such a case, it is not possible to accurately fold up the section 30 with respect to the top surface of the inner packet, so that the outer side flap 3
6 and the inclined edge of the outer side flap 22 may not exactly match, and a gap may be generated between these inclined edges. However, even if such a gap occurs, the gap 42 described above is secured between the inner side flap 34 and the inner side flap 24, so that the inner side flap 34 (the inner wall of the lid 12) is The side flap 36 (outside wall of the lid 12), that is, the protrusion from the lid opening edge can be reliably prevented, and the aesthetic appearance of the hinge lid pack can be secured.

The present invention is not limited to the above-described embodiment, and various modifications are possible. For example, the inner front flap 4 forming the inner front wall of the lid 12
The shape of 0 and its folded form can be variously changed. Further, the inner frame 6 may be a normal one having a rectangular notch at the front edge 6a.

[0024]
