Description

Hinge lid package and its blank

The present invention relates to a hinge lid package particularly suitable for housing stick-shaped smoking articles such as cigarettes and filter cigarettes.

This type of package for housing a cigarette generally has a rectangular parallelepiped appearance, and has a structure in which an integral lid (lid) is provided on the box body via a hinge. Therefore, it is generally called a hinge lid package. In such a cigarette hinge lid package, an auxiliary material called an inner frame is disposed inside the box body.
The hinge lid package is also used for other articles such as boxes for storing stick-shaped confectionery. However, the inner frame is often not arranged like a hinge lid package for cigarettes. In the case of a cigarette box, structural requirements are stricter than a box for storing confectionery.

The reason for this is that, in the case of a cigarette hinge lid package, the cigarette to be stored is easily deformed by external force, and is not a product that is consumed in a short time like confectionery, for example, 20 cigarettes It is necessary to stably store and hold each cigarette until it is consumed. The lid is opened and closed each time the cigarette is taken out, and when the lid is closed, it is required to have a structure capable of maintaining the closed state.
Therefore, the inner frame is employed in the hinge lid package for cigarette as described above. The inner frame cooperates with the box body to protect the internal cigarette, and it has an auxiliary structure such that the lid is not inadvertently opened when there is no opening operation by the user by engaging with the inner surface of the lid. Also works.

Various proposals have hitherto been made for the hinge lid package as described above. For example, as shown in Patent Document 1 (see FIG. 2), the box body has an inclined opening inclined forward and downward on the upper end side. ing. An inner frame having a U-shaped cross section is partially accommodated in the box body so as to protrude from the opening, and is fixed to the front wall or the like of the box body.

On the other hand, the lid of the hinge lid package has a box shape and is connected via a hinge provided behind the box body. The lid is provided so as to cover the inner frame protruding from the opening of the box and close the opening of the box body. Generally, when the lid is closed, the opening edges of the box body and the lid are formed so as to coincide with each other.

By the way, an inner pack is accommodated inside the hinge lid package for cigarettes. This inner pack usually includes a bundle formed of 20 cigarettes in a stacked state and an inner paper for wrapping the bundle. Therefore, the inner pack has four edges along the longitudinal direction of the cigarette, and the outline of these edges is rounded. When the inner pack is housed in the package, not only is there a useless gap between the rounded edge of the inner pack and the corresponding corner edge of the package, but the package has a shape that is difficult to grip due to the corner edge. Become. Therefore, in recent years, many cigarette packages with these four corners rounded (hereinafter referred to as round corners) have been seen. Patent Document 1 shows a hinge lid package of this round corner type.

No. 2007/138861 publication (JP WO2007 / 138861)

However, in the conventional hinge lid package, when the lid is opened, the cigarette inside is taken out and then the lid is closed, there is a possibility that the side wall of the lid collides with the side wall of the inner frame. With this, the lid cannot be opened and closed stably.

As described above, since the inner frame has a U-shaped cross section and includes a side wall, if the opening degree of the lid is within a range where the side wall of the inner frame and the side wall of the lid overlap each other, Things don't happen. That is, if the lid is opened within a range where the side wall of the inner frame and the side wall of the lid are not separated from each other, a collision when the lid is closed can be prevented as described above.
However, there are occasions when the lid is greatly opened, and in this case, the side wall of the lid is separated from the inner frame. Then, when the lid is subsequently closed, a collision occurs as described above.
In the above-described round corner type hinge lid package, since the corners are rounded, more collisions tend to occur than in the case of a general square shape.

The present invention has been made in view of the situation as described above, and an object thereof is to provide a hinge lid package having an improved structure so that a collision with an inner frame does not occur when a lid is closed. .

The above-described object is a box body that has a box-like shape and has an inclined opening that is inclined forward and downward at the upper end, and a box that is connected to a rear edge of the inclined opening via a hinge and opens and closes the inclined opening. And a lid
An inner frame that is partly housed in the box body and disposed so as to have a protruding portion from the inclined opening, and has a U-shaped cross-sectional shape;
When the lid is closed, it covers the protruding portion of the inner frame, and the front opening edge and the left and right side opening edges of the lid are in contact with the corresponding opening edge except for the rear edge of the inclined opening. A hinge lid package,
The side opening edge has a convex portion protruding downward on the hinge side, and the side edge of the inclined opening portion has a concave portion for receiving the convex portion when the lid is closed. Can be achieved by the package.

The convex portion can be formed as a bulging portion having a predetermined width at the tip. Further, the convex portion can be an extended portion that suppresses a collision by expanding a range in which the side wall of the lid overlaps the side wall of the inner frame, and the concave portion is a convex portion of the side opening edge. It is desirable to have a shape corresponding to.
The box body may have round corners rounded at four corners along the longitudinal direction.

The hinge lid package can be easily formed by using a blank that allows the box body and the lid to be integrally formed.

In the hinge lid package of the present invention, the side opening edge of the side wall of the lid has a convex portion protruding downward on the hinge side, and this convex portion expands the range in which the side wall of the lid and the side wall of the inner frame overlap each other. Therefore, it is possible to effectively suppress the above-described collision that occurs when the lid is opened.

It is the perspective view which showed the hinge lid package which concerns on embodiment of this invention, and is the figure which showed the state which closed the lid | cover. It is the perspective view which showed the hinge lid package which concerns on embodiment of this invention, and is the figure which showed the state which opened the lid | cover. It is the figure shown in order to demonstrate the settable area | region of the convex part provided in the side opening edge of the side wall of a lid | cover. It is the figure which showed an example of the blank which can form the box main body and cover of the hinge lid package shown in FIGS. It is the figure which showed an example of the blank of the inner frame used with a hinge lid package.

Hereinafter, a hinge lid package according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 and FIG. 2 are perspective views showing a hinge lid package PA suitable for housing a rod-like smoking article such as a cigarette. FIG. 1 shows a state in which the lid is closed, and FIG. 2 shows that the lid is opened. Indicates the state.
The hinge lid package PA is a round corner type. The basic configuration is substantially the same as that of the conventional hinge lid package. The basic configuration will be briefly described, and then the characteristic parts of the hinge lid package of the present invention will be described in detail.

The hinge lid package PA includes a box body 1, and the box body 1 has an inclined opening 2 at its upper end. A lid 4 is connected to the rear edge of the inclined opening 2 via a hinge (self-hinge) 3, and the lid 4 rotates around the hinge 3 to open and close the inclined opening 2 of the box body 1. It is formed to do.

More specifically, as shown in FIG. 2, the hinge lid package PA includes a box body 1 and has an inclined opening 2 inclined forward and downward at the upper end. The hinge lid package PA further includes an inner frame 10, and the inner frame 10 has a substantially U-shaped cross section. More specifically, the lower side of the inner frame 10 is partially inserted into the box body 1, while the upper side is a protruding portion 11 protruding from the inclined opening 2. Therefore, since the inner frame 10 has a front wall 11a exposed to the outside of the box body 1, a substantially U-shaped notch 12 is formed in the front wall 11a.

On the other hand, the lid 4 has a box shape and can cover the protruding portion 11 of the inner frame 10 to close the inclined opening 2 of the box body 1. That is, when the lid 4 is closed, the opening edges of the lid 4 and the inclined opening 2 on the box body 1 side are in contact with each other.

The hinge lid package PA exemplified here is a round corner type. That is, as apparent from FIGS. 1 and 2, the box body 1 includes arcuate vertical edges 6 as four corner edges extending in the longitudinal direction. These arc vertical edges 6 form round corners that are rounded at the corners of the arc shape when viewed in the cross section of the box body 1. Further, the four corner edges of the lid 4 along the longitudinal direction of the box body 1 are also formed as arc vertical edges 7 similar to the arc vertical edges 6. When the lid 4 is closed, the arc vertical edge 7 of the lid 4 coincides with the corresponding arc vertical edge 6 of the box body 1, and these arc

vertical edges

6, 7 are arranged on the same line.

Further, the inner frame 10 has two arc vertical edges 13 corresponding to the two arc vertical edges 6 on the front wall side in the box main body 1 so as to match the corresponding arc vertical edges 6 from the inside. 1 is fixed to the inner surface of the front side. Therefore, as shown in FIG. 2, the inner pack IP in the box body 1 is held so as to be held in the inner frame 10. The inner pack IP includes a bundle of 20 filter cigarettes in a stacked state and an inner packaging material that wraps the bundle.

In the hinge lid package PA having the basic structure as described above, when the lid 4 shown in FIG. 2 is opened to the closed state shown in FIG. As described above, there is a case in which the lid collides with the side wall of the inner frame.
The hinge lid package PA according to the present invention has a configuration that suppresses such inconveniences. Hereinafter, this point will be described.

Also in the hinge lid package PA, the edge portion of the front wall and the left and right side walls of the lid 4 and the edge portion of the inclined opening of the box body 1 are formed so as to contact each other. More specifically, the front opening edge 4fr of the lid 4 and the left and right side opening edges 4sd-R, 4sd-L are formed on the front side, excluding the rear edge (side on which the hinge 3 is provided) of the inclined opening 2. The front edge 2fr and the left and right side edges 2sd-R and 2sd-L are formed in contact with each other.
However, the side opening edges 4sd-R and 4sd-L (the right side 4sd-R is shown in the figure, but the left side 4sd-L is the same) are protruded downward on the hinge 3 side. Part 4sd-pr.

Corresponding to the shape of the side opening edges 4sd-R and 4sd-L of the lid 4, the side edges 2sd-R and 2sd-L of the inclined opening are provided with the protrusions 4sd-pr when the lid is closed. A receiving recess 2sd-ed is provided. In particular, it is preferable that the concave portion 2sd-ed has a shape just corresponding to the convex portion 4sd-pr of the side opening edge as shown in FIG. Thus, by making it the shape which matched mutually, in the state which closed the lid | cover, it can be set as a flat side surface like the conventional hinge lid package.

If the projection 4sd-pr as described above is provided, as shown in FIG. 2, when the lid 4 is opened, the range in which the side wall overlaps the side wall 14 of the inner frame 10 can be expanded, thereby preventing collision. Acts as an extension for
As is apparent from FIG. 2, the convex portion 4sd-pr faces downward toward the hinge 3 side (preferably, one side of the base of the convex portion 4sd-pr is hooked on the hinge 3). It is desirable to be provided to project. That is, even if the convex portion 4sd-pr is provided only at the center or the front side (the side opposite to the hinge 3) of the side portion, the effect of preventing the collision cannot be expected.

FIG. 3 is a side view of the hinge lid package PA shown in order to explain the settable range of the convex portion provided on the side opening edge.
As shown in FIG. 3, the convex portion 4sd-pr provided on the side opening edge has a straight line with a downward slope drawn from the hinge 3 toward the front opening edge (front opening edge of the lid 4) 4fr. In this case, it is provided so as to protrude downward from the reference line EL at a position close to the hinge 3 side. The reference line EL here is a conventional hinge lid package that corresponds to a side edge line formed by the lid and the inclined opening (an oblique straight line in which the lid and the opening on the box body side are in contact with each other). It is.

The convex portion 4sd-pr needs to be set so as to be at least within the sector shape FA with the length of the reference line EL having the radius R around the hinge 3. When the convex portion 4sd-pr has the maximum shape, this sector shape may be used. However, from the standpoint of obtaining a collision prevention effect by making a simple change to the conventional hinge lid package, as shown in FIGS. 1 and 2, the convex portion protrudes toward the hinge 3 and protrudes downward. That you let me. And the convex part needs to be a shape which does not interfere with the box main body side (namely, the lid | cover 4 can be opened and closed). If it is the convex part which satisfy | fills this condition, it will function as an extension part which expands the range which the side wall of a lid | cover overlaps with the side wall of an inner frame in the range which a lid | cover rotates, and suppresses a collision.
However, as in the convex portion 4sd-pr illustrated in FIGS. 1 and 2, the convex portion provided on the side opening edge is formed as a bulging portion having a predetermined width at the tip, so that the aesthetics and durability are improved. From the viewpoint of That is, the convex portion 4sd-pr is not a triangular shape with a sharp tip (in this case, the tip has no width), but a polygonal shape such as a quadrangle or more, and a concave portion 2sd provided on the edge portion on the box body 1 side. The contacting corner (the lower corner in FIG. 3) is preferably 90 degrees or more. It is more desirable that each corner has a rounded shape. In this way, it does not include the corners on the outer peripheral line that defines the shape of the convex part, but includes a curve in a part of the outer peripheral line, or by making the entire outer peripheral line a curve, the appearance is only beautiful The durability of the convex portion itself can be improved. That is, when the convex portion has a pointed triangular mountain shape or the like, the tip of the convex portion is easily damaged and inferior in durability, but the durability is improved by adopting a structure including a curved line having no angular portion.
In FIG. 3, the case of the quadrangular convex portion 4sd-pr shown in FIGS. 1 and 2 is indicated by a dotted line.

Furthermore, an example of the blank for forming the hinge lid package shown in FIGS.
FIG. 4 shows an example of a blank BL-A in which the box body and the lid of the round corner type hinge lid package shown in FIGS.
The basic configuration and folding procedure of the blank BL-A are well known and will be briefly described below.
The blank BL-A is roughly divided into a main section 20 for forming the box body 1 and a subsection 30 for forming the lid 4. These

sections

20 and 30 are adjacent to the longitudinal direction of the blank BL-A, and are described above. Are connected to each other via a hinge (self-hinge) 3.

The main section 20 has a rear panel 34, a bottom panel 36, and a front panel 38. These

panels

34, 36, and 38 are sequentially arranged along the longitudinal direction of the blank BL-A from the subsection 30, that is, the hinge 3 side. Yes. Panels adjacent to each other in the longitudinal direction of the blank BL-A are connected to each other through a lateral folding line, and these lateral folding lines extend in a direction perpendicular to the longitudinal direction of the blank BL-A. These

panels

34, 36, and 38 are portions for forming the rear wall, the bottom wall, and the front wall of the box body 1, respectively.

Inner side flaps 40 are connected to both sides of the rear panel 34 through vertical folding lines, respectively. The vertical folding line extends along the longitudinal direction of the blank BL-A, and each inner side flap 40 is a portion for forming an inner side portion of the side wall in the box body 1. Further, outer side flaps 42 are respectively connected to both sides of the front panel 38 via vertical folding lines, and these outer side flaps 42 are portions for forming the outer side portion of the side wall. That is, the side wall of the box body 1 is formed by overlapping the inner and outer side flaps 40 and 42 with each other.

Further, as seen in FIG. 4, inner bottom flaps 44 are connected to the lower ends of the inner side flaps 40 via lateral folding lines, respectively, and these inner bottom flaps 44 function as reinforcing members for the bottom panel 36, It is a part for forming the inner part of a bottom wall.

On the other hand, the subsection 30 includes a rear panel 46, a top panel 48, a front panel 50, and an inner front panel 52. These

panels

46, 48, 50, 52 are sequentially arranged in the longitudinal direction of the blank BL-A from the rear panel 34 side. ing. Again, the panels adjacent to each other in the longitudinal direction of the blank BL-A are connected to each other via a horizontal folding line. The rear panel 46, the top panel 48, and the front panel 50 are portions for forming the rear wall, the upper wall, and the front wall of the lid 4, and the inner front panel 52 functions as a reinforcing member for the front panel 50. It is a part for forming the inner part of the wall.

Inner side flaps 54 are connected to both sides of the rear panel 46 via vertical folding lines, and outside flaps 56 are connected to both sides of the front panel 50 via vertical folding lines, respectively. The inner and outer side flaps 54 and 56 arranged on the same side as viewed in FIG. 4 are portions for forming the side wall of the lid 4 by being overlapped with each other.
The portion for forming the side wall has a special shape different from a conventional general blank. That is, the convex portion 54pr is provided on the lower side of the inner side flap 54. The outside flap 56 overlapped with the inner side flap 54 is provided with a concave portion 56pr on the upper side corresponding to the convex portion.
Furthermore, the upper end of the inner side flap 40 described above corresponds to the concave portion 40de corresponding to the convex portion 54pr. Although this portion corresponds to the configuration related to the projection for preventing collision described above, it can be understood from this that the hinge lid package of the present invention can be manufactured only by making a simple change to the shape of the blank BL-A. .

Further, as seen in FIG. 4, an inner top flap 58 is connected to the upper edge of the inner side flap 54 via a horizontal folding line, and these inner top flaps 58 serve as reinforcing members for the top panel 48, and It is a part for forming the inner part of the wall. The inner top flap 58 is also formed in a shape corresponding to the inner side flap 54.

Usually, the above-described horizontal folding line and vertical folding line are formed by indentation lines. However, the above-described vertical folding lines for forming the arc

vertical edges

6 and 7, that is, the

folding zones

6a and 8a are indented lines. Instead, it is desirable to form a round corner with a plurality of longitudinal grooves.

These vertical grooves extend in parallel with each other within the width W of the folding band along the width direction of the blank BL-A. These longitudinal grooves are formed, for example, by forming cuts along the longitudinal direction of the blank BL-A, and the number of longitudinal grooves included in the folding zone is preferably about 5 to 8. The longitudinal grooves reduce the thickness of the blank BL-A and increase the flexibility of the folding zones 6a and 7a. The longitudinal grooves also absorb the difference between the arc lengths of the outer surfaces and the arc lengths of their inner surfaces at the arc

vertical edges

6 and 7. Therefore, when the blank BL-A is folded along the folding band 6a or 7a, folding in the folding bands 6a and 7a becomes easy. In the blank BL-A as described above, a normal packaging machine can be used for folding, whereby a lid that is integral with the box body in the hinge lid package of FIGS. 1 and 2 can be easily formed.

Further, FIG. 5 is a view showing an example of a blank BL-B that can form the inner frame 10 described above. This blank BL-B is provided with an arc vertical edge 13 corresponding to the arc vertical edge 6 on the box side so as to be housed in a round corner type box body, and similarly a folding area 13a for forming a round. Is provided. If the inner frame 10 formed by the blank BL-B is fixed in a box body with a lid assembled from the blank BL-A, the hinge lid package PA shown in FIGS. It can be.

Needless to say, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims.
In the above-described embodiment, the round corner type hinge lid package is taken as an example. However, by applying the present invention to a hinge lid package having four corners which are generally used in the prior art, a lid, an inner frame, Needless to say, the collision can be suppressed.
