Description

Hinge lid type package

The present invention relates to a hinge lid type package.

Conventionally, a box-type package or the like is known as a package (packaging) for containing an article such as a tobacco product. As one form of the box-type package, there is known a hinge-lid type package including a lid (lid) connected to an outer box through a hinge so as to be opened and closed. In addition, this type of hinge lid type package is usually formed by folding a blank in which a folding line is formed at an appropriate position and bonding the appropriate position.

Normally, an outer box and a lid are formed by folding a single blank in a hinge lid type package. FIG. 16 shows a blank 100 for forming a hinge-lid type package having a general rectangular parallelepiped shape. The illustrated blank 100 has a first section R1 that serves as an outer box and a second section R2 that serves as a lid. The first section R1 includes a front wall panel P101 serving as a front wall, a rear wall, a side wall, and a bottom wall of the outer box, a rear wall panel P102, a side wall panel P103, and a bottom wall panel P104. In the illustrated example, the bottom wall panel P104 has a shape and a size corresponding to the entire bottom wall of the outer box. In the first section R1 of the blank, a side flap P105 that reinforces the side wall of the outer box and a bottom flap P106 that reinforces the bottom wall are provided.

On the other hand, the second section R2 of the blank B1 has a front wall panel P107, a rear wall panel P108, a side wall panel P109, and a top wall panel P110 that become the front wall, rear wall, side wall, and top wall of the lid. Further, a side flap P111 that reinforces the side wall of the lid and a top flap P112 that reinforces the top wall are provided in the second section R2.

In recent years, development of a deformed hinge-lid type package having a cross section other than a rectangular cross section, that is, a cross section of a deformed cross section is also in progress. In a rectangular hinge-lid type package having a rectangular cross section, the depth dimension is usually constant, whereas in a deformed hinge-lid type package, the depth dimension is not constant. For example, as shown in FIG. 17, a case is considered where the front wall and the rear wall are inclined in the end region in the width direction of the package, and an inclined wall portion T1 whose depth dimension is gradually narrowed toward the end portion is formed. . The odd-shaped hinge lid type package having the cross section shown in FIG. 17 has a front wall W1 and a rear wall W2 that are not flat as a whole, and the front wall W1 has a front wall central portion W1a and front wall inclined portions W1b on both sides thereof. The rear wall W2 includes a rear wall central portion W2a and rear wall inclined portions W2b on both sides thereof. The front wall inclined portion W1b and the rear wall inclined portion W2b are connected by a side wall W3.

When the outer box and the lid of the odd-shaped hinge lid type package having a cross section as shown in FIG. 17 are formed with a single blank, the bottom wall panel in the first section R1 is replaced with the front wall panel according to the conventional general method. When the top wall panel in the second section R2 is connected between the front wall panel and the rear wall panel, the size of the reinforcing flap for reinforcing the top wall and the bottom wall of the package is increased. It is likely to be difficult to ensure sufficient.

For example, a blank 200 shown in FIG. 18 is an example of a blank for forming a deformed hinge lid type package having a cross section shown in FIG. As in FIG. 16, the first section R1 corresponds to the outer box, and the second section R2 corresponds to the lid. FIG. 18 shows the type of hatching separately for each part of the package after molding. Further, reference symbols P101a, P101b, P102a, and P102b in the first section R1 indicate panels corresponding to the front wall central portion W1a, the front wall inclined portion W1b, the rear wall central portion W2a, and the rear wall inclined portion W2b of the outer box, respectively. . Similarly, symbols P101a, P101b, P102a, and P102b in the second section R2 indicate panels corresponding to the front wall central portion W1a, the front wall inclined portion W1b, the rear wall central portion W2a, and the rear wall inclined portion W2b of the lid, respectively. .

In the blank 200 formed as described above, between the panel P101b and the panel P102b in the first section R1 (second section R2) and the bottom wall (top wall) panel (indicated by reference numeral A1 in FIG. 18). ) Are not connected, and therefore, between the front wall inclined portion W1b and the bottom wall (top wall) or between the rear wall inclined portion W2b and the bottom wall (top wall) in the outer box (lid) during package molding. There may be a gap. Moreover, even if it is going to connect the joining flap for closing these clearance gaps with panel P101b or panel P102b, it may be difficult to ensure the magnitude | size of a joining flap sufficiently in relation to the magnitude | size of clearance gap A1. Then, when the joining flap is provided in the gap A1, it is difficult to properly apply the adhesive to the joining flap at the time of package molding, or the repulsive force when the joining flap is folded is likely to increase. There is also a risk that the adhesive of the industrial flap may be peeled off. As a result, a gap is formed in the molded package, and there is a possibility that an object to be stored falls outside the gap, or the strength and rigidity of the package are reduced.

The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a hinge lid type package formed by folding a single blank into an outer box and a lid. It is an object of the present invention to provide a technique capable of suppressing a decrease in rigidity and strength without forming a gap between each of the other wall surfaces.

In the present invention, the following means are adopted in order to solve the above problems. The present invention includes an outer box having an opening end at an upper portion and capable of accommodating an object to be stored therein, and is rotatably connected to the outer box via a hinge at a rear opening edge of the opening end. A lid for opening and closing an end, and the outer box and the lid are formed by folding a single blank, wherein the outer box and the lid are respectively formed on the center side in the width direction. A front wall and a rear wall that are arranged in a straight line, and a front wall and a rear wall that are formed adjacent to the front wall and the front wall and the rear wall are inclined. An inclined wall portion whose depth dimension is gradually narrowed toward the direction end portion side, and the ceiling wall of the lid and the bottom wall of the outer box are respectively facing the front wall and the rear wall of the front wall and the rear wall. Compatible with walls A central flap that connects the portions to be connected to each other, and an inner flap that is folded from one of the edges of the front wall and the rear wall that correspond to the inclined wall portion and that is disposed adjacent to the central flap And an outer flap which is folded from one of the edges of the front wall and the rear wall corresponding to the inclined wall portion and is fixed to the central flap and the inner flap and covers at least a part thereof It is characterized by including these.

In the hinge lid type package according to the present invention, the top wall and the bottom wall respectively connect a central flap connecting portions corresponding to the facing wall portion of the front wall and the rear wall, and an inclined wall portion in the front wall and the rear wall. The inner flap that is folded from one of the edges corresponding to the inner flap and disposed adjacent to the center flap, and the other edge of the parts corresponding to the inclined wall portions of the front wall and the rear wall And an outer flap fixed to the central flap and the inner flap and covering at least a part of these.

In the region corresponding to the inclined wall portion of the package, the inner flap and the outer flap are overlapped with each other to form the top wall and the bottom wall, and the inner wall starts from the edge of either the front wall or the rear wall. The flap is folded and the outer flap is folded from one of the other edges. By bonding the inner flap and the outer flap configured in this manner to each other, in the package after molding, in the region corresponding to the inclined wall portion, the boundary portion (connecting portion) between the top wall and the other wall surface or the bottom It can suppress that a clearance gap is formed in the boundary part (connection part) of a wall and another wall surface.

Moreover, since the central flap which forms a part of a bottom wall and a top wall connects the parts corresponding to a facing wall part among front walls and a rear wall, a ceiling wall and a bottom wall also in a facing wall part Can be prevented from forming a gap at the boundary portion connected to the front wall and the rear wall.

In the present invention, the central flap is installed at a position corresponding to the facing wall portion of the package, and the space adjacent to the central flap can be used as the installation space for the folded inner flap. Thereby, it becomes difficult for the inner flap to interfere with other members, and as a result, it becomes easy to ensure the size of the inner flap. Therefore, it can suppress that the repulsion force at the time of folding an inner flap becomes large at the time of manufacture of a package, and can suppress that the adhesion | attachment between an inner flap and an outer flap peels off. Therefore, it can suppress suitably that the rigidity and intensity | strength of a package fall. Further, in the package after molding, it is difficult for a gap to be formed at the boundary between the bottom wall of the outer box or the top wall of the lid and the other wall surface, so that an object to be accommodated in the package falls outside the gap. Can be suppressed.

In the present invention, the central flap on the lid side connects the upper edges of the front wall and the rear wall of the lid, and the inner flap and the outer flap that form the top wall of the lid are The upper edge of either the wall or the rear wall may be folded from the upper edge of either one. The central flap on the outer box side connects the lower edges of the front wall and the rear wall of the outer box, and the inner flap and the outer flap forming the bottom wall on the outer box side are The wall and the rear wall may be folded from the lower edge of either one and the other lower edge, respectively.

In the present invention, the inclined wall portion may be formed on both sides of the facing wall portion.

The object to be accommodated in the deformed hinge lid type package according to the present invention is not particularly limited, but an aggregate of rod-shaped articles, for example, tobacco products can be preferably exemplified as the object to be accommodated. That is, the article to be stored according to the present invention may be a tobacco product. Examples of cigarette products include cigarettes (filter cigarettes, double-cut cigarettes (no filter)), cigars (cigars), cigarillos, snus, snuff, chewing tobacco, and electronic cigarettes.

In addition, the means for solving the problems in the present invention can be employed in combination as much as possible.

According to the present invention, in the hinge lid type package formed by folding the outer box and the lid with a single blank, a gap is formed between each of the top wall and the bottom wall and the other wall surface after forming. In addition, it is possible to suppress a decrease in rigidity and strength.

As described above, according to the package 1A according to the present embodiment, the region on the end side has a deformed (special shape) cross section in which the depth dimension is gradually narrowed compared to the region on the center side in the width direction. In this case, the formation of a gap at the boundary between the bottom wall 45 of the outer box 4 and the top wall 35 of the lid 3 and the other wall surface can be preferably suppressed. Therefore, it is possible to prevent the object to be accommodated in the package 1, in the present embodiment, the cigarette 6 from being spilled outside from the gap.

Also in the present embodiment, as in the first embodiment, the bottom center flap F1 is installed at a position corresponding to the “facing wall portion 40a” of the outer box 4, and the spaces on both sides of the bottom center flap F1 are folded. The installation space for the inner flaps F2b and F2c was secured. Similarly, for the top wall 35 of the lid 3, a top center flap F4 is installed at a position corresponding to the “facing wall portion 30a” of the lid 3, and a space on both sides of the top center flap F4 is folded into a top inner flap. The installation space for F5b and F5c was secured. Therefore, the bottom inner flaps F2b and F2c and the top inner flaps F5b and F5c can be sufficiently large, so that the repulsive force is hardly increased when they are folded along the folding line. As a result, at the time of molding the package 1A, it is possible to suitably suppress the adhesion of the bottom inner flaps F2b and F2c and the top inner flaps F5b and F5c. Therefore, it is possible to suppress a decrease in rigidity and strength of the outer box 4 and the lid 3 of the package 1.

The preferred embodiment of the present invention has been described above, but the hinge lid type package according to the present invention can be implemented by combining the embodiments as much as possible. It goes without saying that various modifications can be made to the above embodiment. For example, in the

packages

1 and 1A according to the above-described embodiment, the

inclined wall portions

30b and 30c (40b and 40c) are formed on both sides of the facing wall portion 30a (40a) formed in the region on the center side in the width direction. However, the inclined wall 30b (40b) or 30c (40c) may be formed only on one side of the facing wall 30a.

In the above embodiment, cigarettes have been described as examples of objects to be accommodated in the package, but the present invention is not limited to this. For example, tobacco products other than cigarettes such as cigars, cigarettes, snus, snuff, chewing tobacco, and electronic tobacco may be contained in the package. The package may contain articles other than tobacco products.
