Description

Packaging blanks and packaging boxes

The present invention relates to a packaging blank and a packaging box.

Cigarette packages formed by folding a packaging blank into a box shape along a folding line are widely known as packaging boxes for wrapping tobacco articles such as cigarettes. As is well known, a packaging machine for producing a cigarette package produces a cigarette package by sequentially folding a blank around an inner bundle of cigarettes or filter cigarettes. Usually, a cigarette package is often manufactured using a high-speed packaging machine from the viewpoint of increasing its productivity.

And, as the folding of the packaging blank becomes faster, the spacing between the guide plates installed in the packaging machine for transferring or folding the packaging blank is more delicate from the viewpoint of ensuring the appearance quality in the molded packaging box. As a result of being set to a tight size, there may be a location where the packaging blank transferred along the transfer path contacts the guide plate of the packaging machine too strongly.

When such an excessive contact pressure portion occurs, the outer surface of the packaging blank is damaged, or the ink printed on the blank surface is peeled off, which causes the appearance quality of the packaging box to deteriorate. In addition, the ink peeled off from the packaging blank may adhere to the guide plate at a location where the contact pressure is excessive, and such ink may cause ink stains on the packaging blank by reattaching to the subsequent packaging blank. Become.

Japanese Patent Laying-Open No. 2015-67799 International Publication No. 2014/157337

Conventionally, when a defect is discovered by appearance inspection of a packaging box after molding, it has been necessary to investigate and identify a place that requires machine adjustment in a manufacturing machine in a post-operative or coping therapy each time.

The present invention has been made in view of the above circumstances, and the purpose thereof is a packaging blank that is transferred on a transfer path of a packaging machine when a packaging box is manufactured by folding and forming the packaging blank. Is to provide a technique for easily finding a place where the packaging machine part is in excessively strong contact.

In order to solve the above problems, the present invention forms a stress light emitting part formed by applying stress light emitting ink on a panel included in a packaging blank, so that the packaging box manufacturing process can be performed on the transport path of the packaging machine. It was made possible to easily find where the transported packaging blanks contact the packaging machine parts too strongly.

More specifically, the present invention is a packaging blank that forms a packaging box by being folded along a folding line, and a plurality of panels connected via the folding line, and at least one of the panels. And a stress light emitting portion formed by applying stress light emitting ink to the outer surface of the panel.

The stress-stimulated luminescent ink here is an ink containing a stress-stimulated luminescent material, which is a material that emits light upon receiving a mechanical stimulus of an externally applied force (compression, displacement, friction, impact, etc.). For example, strontium aluminate is used. A main component that contains europium (Eu) as an activator can be preferably used. Such europium-containing strontium aluminate is a compound having a crystal structure in which many lattice defects exist, and is released when electrons captured by the lattice defects are subjected to a mechanical stimulus from the outside. It is thought that light is generated when supplemented by europium again.

According to the packaging blank according to the present invention, if there is an excessive contact pressure portion where the packaging blank is in excessively strong contact with the packaging machine part on the transport path of the packaging machine, Since the light emission phenomenon occurs, the position of the excessive contact pressure can be easily identified by visual observation. In particular, since a large number of packaging blanks are continuously transferred in the transfer path of the packaging machine, the light emission phenomenon occurs continuously at the location where the contact pressure is excessive, and the location where the contact pressure is excessive is visually determined. Easy. As a result, it is possible to quickly and easily find the place where machine adjustment of the packaging machine is to be performed, simply by monitoring (visually) during the manufacturing process of the packaging box, without major modification or alteration of the packaging machine. It becomes possible. That is, the cause of the deterioration of the appearance quality of the packaging box can be easily and quickly investigated, and the countermeasure can be performed earlier than in the past.

Here, the stress light emitting portion may be formed in a predetermined panel inner region that is not in contact with the folding line.

Further, the stress light emitting portion may be formed in a perforation region where a perforation to be torn when the packaging box after molding is opened is installed. In this case, the perforation may be formed at the boundary between the opening band that is cut off from the panel when the packaging box after molding is opened and the panel.

The present invention can also be specified as a packaging box formed by folding any of the packaging blanks described above along the folding line. Further, in this case, the packaging box may be covered with an outer packaging film, and a stress light emitting portion formed by applying stress light emitting ink may be formed on at least a part of the outer packaging film. Further, an opening tape for opening the outer packaging film may be extended to the outer packaging film, and the stress light emitting portion may be formed on the opening tape.

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, when manufacturing a packaging box by folding and forming a packaging blank, it is easy to find a location where the blank transported on the transport path of the packaging machine makes excessive contact with the parts of the packaging machine. Technology can be provided.

The dimensions, materials, shapes, relative arrangements, and the like of the constituent elements described in the present embodiment are not intended to limit the technical scope of the invention only to those unless otherwise specified. Moreover, the packaging box and the packaging blank according to the present invention are cigarettes (filter cigarettes, double-cut cigarettes (no filter)), cigars (cigars), cigarillos, snus, snuff tobaccos manufactured using a high-speed packaging machine. It can be suitably used for smoking articles such as chewing tobacco and electronic tobacco.

<Embodiment 1>
1 and 2 are views showing a cigarette package (hereinafter simply referred to as “package”) 1 which is an example of a packaging box according to the first embodiment. The package 1 is a tan grid type package that includes a package body 2 and a tan grid 3 that extends integrally from the rear edge of the opening end of the package body 2 via a hinge H, and has a substantially rectangular parallelepiped box shape as a whole.

The tongue grid 3 has a top wall 31 that can close the opening end of the package body 2 and a tongue 32 that integrally extends from the top wall 31 via a folding line FL. The package 1 can open and close the open end of the package body 2 by operating the tan grid 3. When closing the package 1, the tongue 32 of the tan grid 3 is overlapped with the front wall 21 of the package body 2 from the outside, and the tip thereof is inserted into the package body 2 through a cut line CL formed on the front wall 21. In addition, a substantially U-shaped notch CA connected to the opening end is formed in the upper portion of the front wall 21 in the package body 2. The notch CA is formed to facilitate the removal of the cigarette from the package body 2 and has the same function as the notch of the inner frame in a normal hinge lid type pack.

In this embodiment, the cigarette packaged in the package 1 is accommodated in the form of an inclusion body IP in the package body 2, for example. The inner body IP may be, for example, 20 cigarettes wrapped with aluminum foil, and is sometimes called an inner pack. Furthermore, the top flaps TF are connected to the open ends of the package body 2 on both side edges thereof via separation lines or folding lines. The top flap TF functions as a reinforcing member for the package body 2 when the inner package IP is packaged, that is, when the package 1 is manufactured. Reference numeral 4 shown in FIGS. 1 and 2 is a “stress light emitting portion” formed on the outer surface of the package 1. Details of the stress light emitting section 4 will be described later.

The package body 2 and the tan grid 3 of the package 1 configured as described above can be formed into a box shape by folding a single packaging blank (hereinafter simply referred to as “blank”) BL1 shown in FIG. it can. In FIG. 3, reference numeral FP denotes a front panel that becomes the front wall 21 of the package body 2. The symbol LP is a lid panel that becomes the tan grid 3. Symbol FL is a folding line that divides each panel. The aforementioned cut line CL is formed in the front panel FP. FIG. 3 shows the outer surface of the blank BL1. The outer surface of the blank BL1 is the surface that becomes the outer surface of the package 1 after the blank BL1 is folded into a box shape. On the outer surface of the blank BL1, for example, a brand logo, a product name, and other decorative characters and patterns (not shown) are printed in advance. Moreover, although the stress light emission part 4 is formed in the outer surface (outermost layer) of blank BL1, the detail is mentioned later.

The details of the blank BL1 will be described. The front panel FP and the lid panel LP are connected from the front panel FP side via the bottom panel BP and the rear panel RP. Further, outer side flaps SFo are respectively connected to both sides of the front panel FP via folding lines FL. Inner side flaps SFi are connected to both sides of the rear panel RP via folding lines FL. A top flap TF and a bottom flap BF are respectively connected to both ends of the inner side flap SFi via a folding line FL.

The blank BL1 configured as described above is manufactured as a package 1 formed into a box shape by being sequentially folded around the cigarette inclusion body IP by a known packaging machine. In the manufacturing process of the package 1 by the packaging machine, for example, an inner package IP is formed by wrapping a three-stage stacked cigarette bundle with aluminum foil, and the blank BL1 is bonded to the upper surface of the inner package IP. For example, as shown in FIG. 4, the blank BL1 is supplied on the inner package IP so that the rear panel RP of the blank BL overlaps the inner package IP, and the rear panel RP is bonded to the upper surface of the inner package IP. . In FIG. 4, the top and bottom of the inclusion body IP and the blank BL1 are shown upside down. In addition, the blank BL1 is supplied onto the inclusion body IP after glue is applied in advance to a predetermined position of the blank BL1, for example, in the process of being conveyed on a blank supply line (not shown).

The inclusion body IP that has received the supply of the blank BL1 is sequentially folded around the inclusion body IP along the folding line FL in the process of being sequentially transferred along a transfer path (not shown) of the packaging machine. As a result, the package 1 is obtained. The folding of the blank BL1 along the folding line FL is realized by a guide plate (not shown) that extends along the transport path of the packaging machine. In addition to the guide plate for folding the blank BL1, the packaging machine includes a guide plate for guiding the blank BL1 in order to transfer the blank BL1 along the transfer path.

In the blank BL1, for example, the inner side flap SFi is folded along the both side surfaces of the inclusion body IP with the top flap TF and the bottom flap BF from the state shown in FIG. Then, the left and right top flaps TF and bottom flaps BF are folded along the both end surfaces of the inclusion body IP, and the state shown in FIG. 5 is obtained.

Further, the blank BL1 is lifted while the front panel FP is gradually folded from the folding line FL between the bottom panel BP and the rear panel RP, with the left and right outer side flaps SFo and the bottom panel BP. On the other hand, the lid panel LP is also lifted while being gradually folded along the folding line FL forming the hinge H. Then, as shown in FIG. 6, the front panel FP and the lid panel LP are folded. That is, the portions that become the tongues 32 of the front panel FP and the lid panel LP are overlapped with each other on the inclusion body IP, and the insertion of the tongues 32 into the cut lines CL formed on the front panel FP is completed. Then, the outer side flap SFo of the front panel FP is folded and overlapped and bonded to the inner side flap SFi. Thereby, folding of the blank BL1 is completed, and the package 1 shown in FIGS. 1 and 2 is completed.

By the way, like the blank BL1 according to the present embodiment, the packaging blank for folding and forming the package 1 for packaging the cigarette (the inclusion body IP) is a so-called high-speed packaging machine from the viewpoint of increasing the productivity of tobacco products. Often used and folded. And, as the manufacturing process of the package 1 (packaging process of the inclusion body IP) becomes faster, the distance between the guide plates for transferring or folding the blank BL1 along the transfer path from the viewpoint of ensuring the appearance quality of the package 1. There is a need to set the dimensions to delicate and tight. As a result, there may be a location where the blank BL1 transferred through the transfer path contacts the guide plate of the packaging machine excessively strongly.

Also, the glue applied to the blank BL1 in the manufacturing process of the package 1 may adhere to the guide plate of the packaging machine. When the glue gradually accumulates on the guide plate, the interval between the guide plates is gradually narrowed. As a result, the contact pressure of the blank BL1 with respect to the guide plate of the packaging machine may become excessively high.

As described above, in the manufacturing process of the package 1, when the contact pressure of the blank BL1 to the guide plate of the packaging machine is excessively high (hereinafter referred to as “excessive contact pressure”) on the transfer path of the blank BL1. The appearance quality of the package 1 may be deteriorated. For example, when the blank BL1 comes into excessively strong contact with the guide plate of the packaging machine, the outer surface of the blank BL1 may be damaged or the ink printed on the blank BL1 may be peeled off. In addition, the ink attached to the guide plate due to the separation from the blank BL1 may adhere again to the subsequent blank BL1, so that the outer surface of the blank BL1 may be stained by the ink.

Conventionally, the appearance of a package after manufacture is inspected, and when a defect in appearance quality is found, each time an excessive contact pressure point that requires machine adjustment in the manufacturing machine is investigated after-the-fact or treatment. It was necessary, and it was not easy to find an excessive contact pressure point at an early stage. On the other hand, in this embodiment, in order to enable easy discovery of a contact pressure excessive point on the transfer path of the blank BL1 without requiring a large-scale modification or alteration of the packaging machine, The stress light emission part 4 was provided on the outer surface (see FIG. 3). Hereinafter, the stress light emission part 4 formed in the outer surface of blank BL1 is demonstrated in detail.

Here, the stress light emitting portion 4 is formed by applying stress light emitting ink to the outer surface of the blank BL1, and is formed in a panel connected via a folding line FL. Examples of the panel here include the front panel FP, the lid panel LP, the rear panel RP, and the like shown in FIG. Moreover, in FIG. 3, the area | region range in which the stress light emission part 4 is formed is illustrated by hatching. In the example shown in FIG. 3, a predetermined panel inner region (hatching region in FIG. 3) that is not in contact with the folding line FL among the outer surfaces of the front panel FP, the lid panel LP, the bottom panel BP, the rear panel RP, and the outer side flap SFo. Is formed. However, the stress light emission part 4 may be formed in the whole panel (all area | regions) connected via the folding line FL. Moreover, the stress light emission part 4 may be formed in the one part panel with which blank BL1 is provided, and may be formed in all the panels.

The stress luminescent ink that forms the stress luminescent portion 4 includes a stress luminescent material that is a material that emits light in response to a mechanical stimulus of an externally applied force (compression, displacement, friction, impact, etc.). In other words, the stress-luminescent ink is an ink that emits light upon receiving a mechanical stimulus of an externally applied force (compression, displacement, friction, impact, etc.). The stress-stimulated luminescent material in the present embodiment contains strontium aluminate as a main component and europium (Eu) as an activator. Europium-containing strontium aluminate is a compound having a crystal structure in which many lattice defects exist. The luminescence mechanism of europium-containing strontium aluminate is not fully understood, but electrons captured by lattice defects are released when mechanically stimulated from the outside, and the released electrons become europium again. It is thought that light is generated when supplemented.

The stress-stimulated luminescent ink may contain materials contained in ordinary inks such as a diluent, a dispersant, a viscosity modifier and the like in addition to the stress-stimulated luminescent material (europium-containing strontium aluminate). Here, the stress luminescent ink may contain 5 to 50 parts by weight of a stress luminescent material (europium-containing strontium aluminate) per 1 part by weight of a diluent (for example, colorless medium). However, the content of the stress luminescent material in the stress luminescent ink is not particularly limited.

Here, if the layer thickness in the stress light emitting portion 4 is too thin (too small), there is a risk that the amount of light emitted when a mechanical stimulus is applied from the outside may be insufficient, and if the layer thickness is too thick (too large). And ink cracks are likely to occur. Therefore, from the viewpoint of ensuring both the amount of light emission in the stress light emitting portion 4 and the suppression of ink cracking, the layer thickness of the stress light emitting portion 4 is preferably adjusted within the range of 1 μm to 50 μm, and is adjusted within the range of 3 to 30 μm. It is more preferable.

In addition, the average particle diameter of the stress-stimulated luminescent material contained in the stress-stimulated luminescent ink is not particularly limited. Moreover, the base material of the blank BL1 to which the stress-luminescent ink is applied is not particularly limited, and examples thereof include fine paper, art paper, coated paper, cast coated paper, and synthetic resin impregnated paper. Moreover, as for the color of the base material of the blank BL1 to which the stress-luminescent ink is applied, the light-colored system is more likely to obtain a light-emitting effect when a mechanical stimulus is applied to the stress-luminescent material, and the base material is white. And particularly preferred. In the Munsell color system (Munsell color system), there is an embodiment in which the brightness of the base material of the blank BL1 is set to 6 or more and 10 or less. Moreover, it is preferable to set the lightness of the base material of the blank BL1 to 7 or more and 10 or less, and it is particularly preferable to set it to 8 or more and 10 or less. In the Munsell color system, the brightness of white is 10, and the brightness of black is 1.

Also, various printing methods can be adopted as the printing method of the stress-luminescent ink on the blank BL1. For example, the stress-luminescent ink may be printed by offset printing, flexographic printing, gravure printing, screen printing, or the like. In addition, from the viewpoint of increasing the amount of light emission when mechanical stimulus is applied to the stress light emitting portion 4 from the outside, it is preferable to apply the stress light emitting ink by flexographic printing, gravure printing, or screen printing. By doing in this way, it becomes easy to ensure the application quantity of stress light emission ink, and there exists an advantage that it is easy to ensure the light emission quantity in the stress light emission part 4. FIG.

<Effect>
According to the blank BL1 configured as described above, when the transfer path of the packaging machine is transferred in the manufacturing process of the package 1, the contact of the blank BL1 with the guide plate is present if there is an excessive contact pressure location on the transfer path. When the pressure is excessively increased, the stress-stimulated luminescent material contained in the stress-stimulated luminescent ink of the stress-stimulated luminescence part 4 emits light. In addition, since a large number of blanks BL1 are continuously conveyed at a high speed in the transfer path of the packaging machine, the light emission phenomenon occurs continuously at the above-mentioned contact pressure excessively locations. It can be easily identified. As described above, according to the blank BL1 in the present embodiment, mechanical adjustment of the packaging machine (e.g., monitoring (visually) during the manufacturing process of the package 1 without modification or alteration of the packaging machine) It is possible to quickly and easily find a place where guide plate interval adjustment, shape change, and the like are to be performed. In this way, the cause of the deterioration in the external appearance quality of the package 1 can be easily and quickly investigated, so that the countermeasure can be performed earlier than in the prior art. Is less likely to be damaged.

Further, when the paste applied to the blank BL1 gradually accumulates on the guide plate of the packaging machine during the manufacturing process of the package 1, an excessively large contact pressure portion is suddenly generated on the transfer path of the blank BL1 at a certain timing. It is assumed that In contrast to this, according to the blank BL1 according to the present embodiment, it is easy to identify an excessively large contact pressure portion by visually confirming the light emission of the stress light emitting section 4.

Further, as shown in FIGS. 1 and 2, naturally, the stress light emitting portion 4 is also formed on the outer surface of the package 1 formed from the blank BL1. As described above, the stress light emitting portion 4 formed on the outer surface of the package 1 can be used for various purposes. For example, after consuming (smoking) all the cigarettes in the package 1, when the owner (consumer) squeezes the package 1 when discarding the package 1, the stress luminescent material of the stress luminescent part 4 is mechanically It emits light when a stimulus is applied. Thereby, visual interest and enjoyment can be provided to the owner of the package 1, and the ownership satisfaction of the package 1 can also be increased. In addition, when the owner discards the package 1, a secondary effect can be expected that the volume of the discarded waste can be reduced by crushing the package 1 in an attempt to cause the stress light emitting unit 4 to emit light.

Moreover, the owner of the package 1 does not stop at the time of disposal of the package 1, and gives mechanical stresses such as compression, displacement, friction, and impact to the stress light-emitting unit 4 from the outside at an arbitrary timing using, for example, a fingertip or a nail. By performing the operation (hereinafter referred to as “mechanical stimulus applying operation”), the stress light emitting unit 4 can emit light. That is, in this way, the light emission phenomenon of the stress light emitting portion 4 formed on the outer surface of the package 1 can be enjoyed at an arbitrary timing. In addition, the stress light emitting unit 4 can be easily made to emit light by a mechanical stimulus applying operation with a fingertip or the like without requiring a special instrument or machine, which is highly convenient. The stress light emitting unit 4 emits light only when an external force is applied by a mechanical stimulus applying operation with a fingertip or the like, and the light emission disappears when the applied state of the external force is canceled. It can be carried out.

Further, since the owner can determine the presence or absence of the light emission phenomenon of the stress light emitting unit 4 only by performing a mechanical stimulus applying operation with a fingertip or the like, it is possible to easily determine the authenticity of the cigarette accommodated in the package 1 or inside. Can be used to prevent counterfeiting of products.

Further, as described above, the blank BL1 in the present embodiment is formed in a predetermined panel inner region that is not in contact with the folding line FL. This is because, when the blank BL1 is folded along the folding line FL, the blank BL1 is folded mainly because the panel inner region is in contact with the guide plate. That is, in the panel of the blank BL1, it is of course possible to form the stress light emitting portion 4 in the panel edge region in contact with the folding line FL, but the stress light emitting portion 4 formed in the panel edge region is formed in the panel inner region. Since the contribution to the discovery of the excessive contact pressure portion is relatively lower than that of the stress light emitting portion 4, in this embodiment, the stress light emitting portion 4 is not formed in the panel edge region but is formed in the panel inner region. . Thereby, while ensuring the function of easily finding a contact pressure excessive point on the transfer path of the blank BL1, it is possible to reduce the amount of stress-luminescent ink applied to the blank BL1, and to reduce the manufacturing cost of the blank BL1. Reduction can be achieved.

In addition, the blank BL1 in this embodiment may be a regular blank for shipping the package 1 after manufacture as a product, or a blank for prior confirmation for confirming in advance whether or not the specifications of the packaging machine are appropriate. There may be. For example, when the specifications such as the shape and interval of the guide plate in the packaging machine are changed, the package 1 is used by using a blank for preliminary confirmation (in this case, the blank BL1 shown in FIG. 3 becomes a blank for preliminary confirmation). When making a prototype, it may be confirmed whether or not the packaging machine has a portion to be mechanically adjusted based on whether or not the light emission phenomenon of the stress light emitting section 4 occurs. Thus, in the trial production stage of the package 1, it is advantageous from the viewpoint of cost to specify the location where mechanical adjustment should be performed using a blank for preliminary confirmation.

The inner front flap P12 is superimposed on the front wall panel P11 to reinforce the front wall of the lid 3A. Moreover, the side wall panel P13 used as the side wall in the lid 3A is connected with the both-sides edge of the front wall panel P11, respectively. The inner side flap P9 described above overlaps and adheres to the side wall panel P13, thereby reinforcing the side wall of the lid 3A.

As in the first embodiment, the blank BL2 formed as described above is folded along the folding line FL by a known packaging machine, and an appropriate place is bonded to form a package 1A as an example of a packaging box. The

<Embodiment 3>
Next, Embodiment 3 will be described. FIG. 9 is a diagram illustrating a package 1B according to the third embodiment. The package 1B includes a package main body 2B and a lid 3B connected to the package main body 2B via a hinge H, and has a substantially rectangular parallelepiped box shape as a whole. FIG. 9 shows the package 1B before opening.

An opening band 6 that crosses the package 1B in the width direction is formed on the front surface of the package 1B. A tongue-shaped tip knob 60 is formed at the tip of the opening band 6. The unsealing band 6 is formed as a region sandwiched between a pair of

parallel perforations

6a and 6b as a cutting line formed along the extending direction. That is, the

perforations

<Embodiment 4>
Next, Embodiment 4 will be described. FIG. 10 is a diagram illustrating a package 1C according to the fourth embodiment. The package 1C is a hinge lid package having a package body 2C and a lid 3C. FIG. 10 shows the package 1 C before opening, and the whole is covered with the outer packaging film 7. The outer packaging film 7 is provided with an opening tape (tier tape) 71, and a tip knob portion 72 is provided on the distal end side of the opening tape 71.

The outer packaging film 7 is a transparent or translucent film material, and is made of a material such as polypropylene, cellophane, or polyethylene terephthalate. However, materials other than those listed above may be used as the material of the outer packaging film 7. The opening tape 71 is a belt-like member wound around the package body 2 C along the horizontal direction, and is attached to the back surface (inner surface) side of the outer packaging film 7. The back surface (inner surface) of the outer packaging film 7 here is the surface facing the outer surface of the blank forming the package body 2C. When the package 1C is opened, the smoker (consumer) picks and pulls the tip knob 72. Thereby, the opening tape 71 can tear the outer packaging film 7, and can open the package 1C. In the package 1 C in the present embodiment, the stress light emitting portion 4 is formed by applying stress light emitting ink to at least a part of the outer packaging film 7.

FIG. 11 is a view showing the developed sheet-like outer packaging film 7. In FIG. 11, the back surface of the outer packaging film 7 is shown. The back surface of the outer packaging film 7 is the surface facing the outer surface of the package 1C in a state where the package 1C is covered as described above. Reference numeral 7A shown in FIG. 11 is a “side heat seal part”, reference numeral 7B is an “upper surface heat seal part”, and reference numeral 7C is a “lower heat seal part”. The sheet-like outer packaging film 7 is wound along the outer surface of the package 1C, and each heat seal portion is heat sealed (welded). More specifically, the sheet-like outer packaging film 7 is folded around the package 1C and heat-sealed in a state where the side surface heat seal portions 7A are overlapped. Thereafter, heat sealing is performed in a state where the upper surface heat seal portions 7B are overlapped with each other. Similarly, heat sealing is performed in a state where the lower surface heat seal portions 7C are overlapped with each other. Thereby, the package 1 C is sealed by the outer packaging film 7.

Returning to FIG. 11, the stress light emitting portion 4 is not provided in each heat seal portion (side heat seal portion 7 A, upper surface heat seal portion 7 B, lower surface heat seal portion 7 C) of the outer packaging film 7, except for the heat seal portion. The stress light-emitting portion 4 is provided in a region (a part or all of the region). Here, the reason why the stress light emitting portion 4 is not provided in the heat seal portion is that when the stress light emitting ink is applied to the region, there is a possibility that it cannot be welded well. Moreover, as shown in FIGS. 10 and 11, the stress-stimulated luminescent portion 4 is formed by applying the stress-stimulated ink to the opening tape 71 in the outer packaging film 7.

In the present embodiment, since the stress light emitting ink is applied to the outer surface of the outer packaging film 7 that covers the package 1C and the stress light emitting portion 4 is provided, the owner of the package 1C can select, for example, a fingertip or a nail at an arbitrary timing. The stress light emitting part 4 can be caused to emit light by performing a mechanical stimulus applying operation for applying a mechanical stimulus such as compression, displacement, friction, and impact to the stress light emitting part 4 of the envelope film 7 from outside. Thereby, visual interest and enjoyment can be provided to the owner of the package 1C, and satisfaction of ownership of the package 1C can be increased. In particular, according to the envelope film 7 according to the present embodiment, since the stress light emitting portion 4 is formed on the opening tape 71, when the package film 1C is opened, when the outer package film 7 is torn by the opening tape 71, the mechanical stimulus Thus, the stress light emitting portion 4 can emit light. That is, there is an advantage that an attractive element can be added to the operation of opening the package 1C.

In the present embodiment, the stress light emitting part 4 may be disposed on the inner surface side of the envelope film 7, and the stress light emitting part 4 emits light suitably by applying a mechanical stimulus to the stress light emitting part 4 through the film. Can be made. In the present embodiment, the stress light emitting section 4 may be provided on the outer surface of the package 1C (package main body 2C, lid 3C).

Although the preferred embodiments of the present invention have been described above, it is obvious to those skilled in the art that the packaging blank and the packaging box according to the present invention can be variously changed, improved, combined, and the like.
