The hinged lid package is generally made of paper, and in the paper hinged lid box, there is a problem that a gap is generated between the lid and the body due to the deflection of the paper. In order to solve such a problem, a technique of preventing the generation of a gap by fitting a cover to a part of the body has been proposed. However, in this prior art, there is a concern that the construction of the package is complicated. In addition, deterioration of paper at the fitting portion due to repeated fitting is also a concern. In addition, such a problem is not limited to the hinge lid package, and the slide package having the inner box and the outer box is the first, and the entire paper product has such a problem. Especially in the end of paper products, deflection and deterioration are particularly worrying.

The present invention has been made in view of the above problems, and an object thereof is to provide a technique for suppressing deflection and deterioration of an end portion of a paper product.

In order to solve the above problems, the present invention is to bend the end of the paper product, and to work on the bending method, and to apply tension to the bent portion in advance.

More specifically, the present invention provides an end structure of a paper product, comprising: an end portion of the paper product; a bent portion connected to the end portion, bent toward the end portion, and then at the end portion a straight line (scored line) provided at a boundary between the end portion and the bent portion, wherein the bent portion is bent; and a rule is provided in the vicinity of the fold line and at the end portion or The aforementioned bent portion varies with the distance from the aforementioned fold line When the bent portion is bent, the end portion or the bent portion is bent.

One of the features of the end structure of the paper product of the present invention is that it has a scribe line in addition to the fold line. The scribing system is the same as the general scribing line, and is used to make the paper product easy to bend, and can be formed by creases, seam holes, and thin walls. The paper product is originally bent at the scribing position, but in the end structure of the paper product of the present invention, although it has a scribe line for bending, it is opposite to the scribe line and is different from the scribe line. Bend. Here, when the paper product is bent, there is a restoring force to be restored in the bent position. In the end structure of the paper product of the present invention, in addition to the bending of the bent portion, the scribe line is also bent, and the scribe line also has a restoring force. Furthermore, the underline is formed so as to vary with the distance from the fold line. Therefore, for example, when the scribe line is compared with a straight line parallel to the fold line, the scribe line becomes less likely to be bent. Therefore, when the paper product is bent by a linear fold line, since the resistance is generated while the scribing is generated, a stronger restoring force is exerted. Furthermore, the bent portion is followed by the end portion. As a result, in the end portion of the paper product, although a stronger resilience is produced, it cannot be restored to its original state. Therefore, in the end structure of the paper product of the present invention, the tension acts on the inside of the end portion of the paper product, and the end portion of the paper product is suppressed from being bent. In other words, in the end structure of the paper product of the present invention, the deflection of the paper due to deterioration over time is suppressed by controlling the tension, that is, by controlling the deflection. Further, in the end structure of the paper product of the present invention, the bent portion is bent to have a double structure, and has a very simple structure, so that it is less likely to deteriorate.

The aforementioned scribing system can be set to gradually increase the distance from the aforementioned fold line V-shaped that becomes longer and shorter. Although it is only an example of a scribe line, by setting a scribe line into a V shape, it is easy to process a scribe line, and it is easy to adjust a tension. The scribing line may be linear or curved. The position of the V-shaped scribe line may be provided to cover the entire fold line, or may be provided at a part of the fold line (for example, the center portion or the end portion). The number of V words can be one or plural. In other words, the scribe line can be configured to have a plurality of the aforementioned V-shapes. By setting a plurality of V words, a stronger tension can be exerted. The apex of the V-shaped line may be provided on either the end side of the paper product or the side of the bent portion, but it is more preferably provided on the side of the bent portion. By providing the scribe line on the side of the bent portion, the direction of the restoring force of the crease line and the scribe line can be made uniform, and a stronger tension can be exerted.

Here, the scribe line may extend from both end portions of the linear fold line and form a predetermined angle with the fold line. In the present invention, the base ends of the two lines constituting the V-shape are provided as an example of both end portions of the fold line. By extending the V-shaped scribe line from both end portions of the fold line, the scribe line is close to the fold line in the vicinity of both end portions of the fold line, and the distance from the fold line gradually increases toward the center. Therefore, the paper product is not easily noticeable when the scribe line is bent, and the change in the shape of the paper product due to the setting of the scribe line can be reduced. When the predetermined angle is increased, the tension becomes large because it is not easily bent at the scribe line. On the other hand, when the predetermined angle is decreased, it is easy to bend at the scribe line, and the tension is made small. Further, when the predetermined angle is increased, the thickness of the end portion is increased, and the shape of the paper product is changed, which is a concern for the paper product. On the other hand, by reducing the predetermined angle, the shape of the paper product can be reduced. Variety. Therefore, the predetermined angle can be designed in consideration of the tension and the change in the shape of the paper product. In addition, the scribe line may be linear or curved. When the scribe line is curved, the angle formed by the scribe line and the fold line can be set to an angle formed by a tangent line of the curved line and a straight line.

In addition, the aforementioned predetermined angle can be set to 0.1 to 5.0. degree. Preferably, the predetermined angle is set to be 0.2 to 2.0 degrees. More preferably, the aforementioned predetermined angle can be set to 0.5 to 1.0 degrees. Thereby, sufficient tension can be exerted, and also variations in the shape of the paper product can be suppressed.

In addition, the bent portion may be configured such that the front end portion is followed by the Ends. The tension can be effectively acted upon by the front end portion that produces the maximum action with the restoring force. The bent portion may also be provided so as to be entirely attached to the end portion.

Further, the aforementioned scribing line may be provided at the end portion When it is provided in the bent portion, the tension acting on the inside of the end portion of the paper product is different. When the aforementioned scribe line is provided at the end, the end structure of the paper product can expand the end side. On the other hand, when the scribe line is provided in the bent portion, the end structure of the paper product can expand the bent portion side (the end portion side is recessed). In other words, the direction in which the end structure is expanded (the direction of the recess) can be determined depending on the position at which the scribe line is provided. Therefore, the position where the scribing is provided can be appropriately changed in accordance with the use of the paper product.

Here, the present invention can be specifically designated to have the above paper A package constructed with the end of the article. For example, the present invention is a paper package comprising: an end portion forming at least a portion of an opening edge of the paper package; a bent portion connected to the end portion and bent at the end portion side, and And the end portion; a linear fold line is provided at the end portion and the aforementioned bend The boundary of the portion is bent by the bent portion; and the scribe line is provided in the vicinity of the fold line, and is provided at the end portion or the bent portion, which varies according to the distance from the fold line, and is in the aforementioned bend When the portion is bent, the end portion or the bent portion is bent.

In the paper packaging box of the present invention, it is formed into a paper system. The inside of the end of at least a portion of the opening edge of the package creates a pulling force. Therefore, the deflection in the opening of the package due to deterioration over the years is suppressed. Therefore, for example, when the package is constituted by the lid portion and the accommodating portion, it is difficult to form a gap between the lid portion and the accommodating portion. Further, since the bent portion of the paper packaging box of the present invention is bent to have a double structure and has a very simple configuration, the opening of the package is not easily deteriorated.

The paper packaging box can be set, for example, to include: a substantially rectangular shape The body-shaped accommodating portion accommodates the object to be stored and has an opening for taking out the object to be stored; and the lid portion covers at least the opening. In such a package, the end structure of the present invention described above can be used for the end of the cover, such as the upper wall of the cover or the end of the front wall of the cover. Further, the end structure of the present invention described above may be used as an end portion of the opening of the accommodating portion. Specifically, the present invention relates to a paper package comprising: a substantially rectangular parallelepiped housing portion for receiving an object to be received and having an opening for taking out the object to be stored; and a cover portion covering at least the opening; the paper system The packaging box includes: a bent portion connected to an end portion of at least one of an end portion of the lid portion and an opening portion of the accommodating portion, and is bent at an inner side of the package, and then An end portion; a linear fold line provided at a boundary between the end portion and the bent portion to bend the bent portion; and a scribe line in the vicinity of the fold line The end portion or the bent portion is changed in accordance with the distance from the fold line, and when the bent portion is bent, the end portion or the bent portion is bent. By bending the bent portion to the inside of the package, the tension toward the inside can be applied to the end portion of the lid portion or the end portion of the opening of the accommodating portion. As a result, a gap is less likely to occur between the lid portion and the accommodating portion.

In addition, the paper package can be set, for example, to include: a box for accommodating the object to be stored and having an opening for taking out the object to be stored; and an outer box for accommodating the inner box and having a take-out opening for taking out the inner box. In such a package, the end structure of the present invention described above can be used for the end of the opening of the inner casing. Further, the end structure of the present invention described above may be used as an end portion of the outer casing for taking out the inlet and outlet. Specifically, the present invention relates to a paper package, comprising: an inner box for accommodating the object and having an opening for taking out the object; and an outer box for accommodating the inner box and having the inside of the box The paper box is provided with: a bent portion connected to an end of at least one of an end portion of the opening of the inner box and an end portion of the outer box And bending at the inner side of the package, and then at the end; a linear fold line is provided at a boundary between the end portion and the bent portion, and the bent portion is bent; and a scribe line is formed at the fold line In the vicinity of the end portion or the bent portion, which varies depending on the distance from the fold line, and when the bent portion is bent, the end portion or the bent portion is bent. By bending the bent portion to the inside of the package, the tension toward the inside can be applied to the end of the opening of the inner casing or the end of the outer casing from which the outer casing is taken out. As a result, a gap is less likely to occur between the inner box and the outer box.

In addition, the end construction of the paper product to which the present invention is applied The paper package is not limited to the above. The end structure of the paper product of the present invention can be widely used at the end of a paper package and is the end of a bendable paper package. Further, in the above-described package, although the tension acts on the inner side of the package, the tension may be applied to the outer side of the package depending on the application. For example, in a package having a cover portion having a front wall and a portion having a front wall overlapping the front wall of the cover portion, a tension can be applied to the package at the end of the front wall of the housing portion. The outer end structure. Thereby, the resistance of the front wall of the container and the front wall of the lid portion can be increased, and the closure property can be improved.

In addition, the present invention can also be specifically designated as the paper described above. The prototype of the box. For example, the present invention is a prototype sheet of a paper package, the paper package comprising: a substantially rectangular parallelepiped housing portion for receiving an object to be received, and having an opening for taking out the object; and a cover portion, at least Covering the opening; the prototype sheet includes: a cover panel constituting the cover portion; and a receiving panel connected to the cover panel or a member different from the cover panel to constitute the accommodating portion; the reinforcing panel; The end of the cover panel and the end of the receiving panel are connected to each other and are bent inside the package, and then at least one of the cover panel and the receiving panel a linear fold line provided at an end of the cover panel or at an interface between an end of the receiving panel and the reinforcing panel, wherein the reinforcing panel is bent; and a scribe line is provided in the vicinity of the fold line and One of the cover panel or the receiving panel and the reinforcing panel, along with the distance from the fold line In the case of the change, when the reinforcing panel is bent, one of the cover panel or the receiving panel and the reinforcing panel is bent.

<production step>

Fig. 1 is a view showing the steps of producing the end structure of the paper product of the first embodiment. (a-1) to (a-4) on the left side of the first figure show the end of the paper product Top view. (b-1) to (b-4) on the right side of Fig. 1 are plan sectional views showing the end portions of the paper product.

The structure of the end structure of the paper product of the first embodiment In the first place, the paper product is subjected to scribing RL processing. As shown in Fig. 1 (a-1) and Fig. 1 (b-1), the end structure 1 of the paper product according to the first embodiment includes an end portion 2 of a paper product, a bent portion 4, and an end portion. The portion 2 is connected, and is bent at the end portion 2 side, and then to the adhesive portion 3 of the end portion 2; the linear fold line BL is provided at the boundary between the end portion 2 and the bent portion 4, and the bent portion 4 is bent; the V shape The scribe line RL is provided in the vicinity of the fold line BL, and is provided in the bent portion 4, which varies depending on the distance from the fold line BL, and is bent when the bent portion 4 is bent.

Figure 2 is a view showing the end of the paper product of the first embodiment. An enlarged top view of the structure before bending. One of the features of the end structure 1 of the paper product according to the first embodiment is that a V-shaped scribe line RL is provided in the vicinity of the linear fold line BL. The scribe line RL is the same as a general scribe line and is used to make the paper product easy to bend. The scribe line RL can be formed by creases, pierced holes, and thin walls. The processing system of the scribe line RL includes, for example, a conventional processing technique, processing by a plotter, and processing by press forming.

In the scribe line RL of the first embodiment, two straight lines forming a V-shape extend from both end portions of the linear fold line BL, and form a predetermined angle α with the fold line BL. In the first embodiment, the predetermined angle α is 1 degree. The predetermined angle α is not limited to this angle. The predetermined angle α can be set to 0.1 to 5.0 degrees. Preferably, the predetermined angle α can be set to 0.2 to 2.0 degrees. More preferably, the predetermined angle α can be set to 0.5 to 1.0 degrees. When the predetermined angle α is increased, since it is not easily bent by the scribe line RL, the tension becomes large. On the other hand, when the predetermined angle α is decreased, it is easy to bend at the scribe line RL, and the tension is made small. Further, when the predetermined angle α is increased, the thickness of the end portion is increased, and the shape of the paper product is changed, so that there is a doubt that the paper product is affected. On the other hand, by reducing the predetermined angle α, the change in the shape of the paper product can be reduced. Therefore, the predetermined angle α can be designed in consideration of variations in the shape of the tension and the paper product. In addition, the scribe line RL may also be curved.

Go back to the description in Figure 1. As shown in Figure 1 (a-2), (a-3), In the production of the end portion structure 1 of the paper product according to the first embodiment, as shown in Figs. 1 (b-2) and (b-3), the linear fold line BL is then bent. In the end structure 1 of the paper product according to the first embodiment, the bent portion 4 is bent in the V-shaped scribe line RL except that the fold line BL is bent. Therefore, the vicinity of the broken line BL and the scribe line RL is slightly V-shaped as shown in Fig. 1(a-3). In addition, the drawing emphasizes that when the predetermined angle α is 1 degree, the vicinity of the fold line BL and the scribe line RL is substantially linear. The same applies to other drawings.

As shown in Figure 1 (a-4) and Figure 1 (b-4), at the first In the production of the end structure 1 of the paper product of the embodiment, the bent portion 4 is next followed by the sticky region 3 of the end portion 2. In the first embodiment, the front end portion of the bent portion 4 is followed. The tension can be effectively acted upon by the front end portion which is most effective in the restoring force. Further, the bent portion 4 may be entirely attached to the end portion 2. According to the above aspect, the end structure 1 of the paper product of the first embodiment is completed.

<constitution>

Fig. 3A is a view showing the end structure of the paper product of the first embodiment; Top view. Fig. 3B is a cross-sectional view taken along line A-A of Fig. 3A. Fig. 3C is a cross-sectional view taken along line B-B of Fig. 3A. In the end structure 1 of the paper product according to the first embodiment, the linear fold line BL and the scribe line RL are bent, and the end portion 2 and the bent portion 4 are stacked to have a double structure. Further, the end portion 2 and the bent portion 4 are curved so as to expand the side of the bent portion 4.

<Action effect>

The paper product is originally bent at the scribing position, but in the end structure 1 of the paper product of the first embodiment, it is bent at a fold line BL different from the scribe line RL. Here, when the paper product is bent, there is a restoring force to be restored at the bent position. In the end structure 1 of the paper product according to the first embodiment, in addition to the bending of the fold line 4, the bent line 4 is bent at the scribe line RL, and the scribe line RL also has a restoring force. Further, the scribe line RL is formed in a V shape which changes in accordance with the distance from the fold line BL. Therefore, for example, in a case where the scribe line RL is formed in a straight line parallel to the fold line, the V-shaped scribe line RL is not easily bent. Therefore, when the paper product is bent at the linear fold line BL, the scribe line RL is bent while generating resistance, and a stronger restoring force acts. Further, the bent portion 4 is followed by the end portion 2. As a result, in the end portion 2 of the paper product, although there is a more conventional resilience generating effect, it cannot be restored. Therefore, in the end structure 1 of the paper product according to the first embodiment, the tension acts on the inside of the end portion 2 and the bent portion 4, and the bent portion 4 side is inflated. As a result, the end portion 2 and the bent portion 4 are bent to expand the side of the bent portion 4. In the end structure 1 of the paper product of the first embodiment, since the tension acts on the inside of the end portion 2 and the bent portion 4 in advance, it is possible to suppress the deflection of the paper due to deterioration over the years. In addition, In the end structure 1 of the paper product according to the first embodiment, the end portion 2 and the bent portion 4 are stacked to have a double structure, and the structure is extremely simple, so that it is less likely to deteriorate.

In addition, by making the V-shaped scribe line RL from the fold line BL The both end portions are extended such that the scribe line RL approaches the fold line BL in the vicinity of both end portions of the fold line BL, and the distance from the fold line BL gradually increases toward the center. Therefore, the paper product is not easily noticeable when the scribe line RL is bent, and the change in the shape of the paper product caused by the provision of the scribe line RL can be reduced.

<Modification 1>

The end structure 1 of the paper product of the first embodiment is only an example. For example, as shown in FIG. 4, the scribe line RL may be provided with a V-shaped scribe line RL at the center of the fold line BL. When the distance from the crease line BL to the apex of the scribe line RL is the same as that of the first embodiment, in the example (variation 1) shown in Fig. 4, the predetermined angle α is more than that of the first embodiment. Big. As a result, a larger tension can be applied to the inside of the end portion 2 and the bent portion 4.

<Modification 2>

Further, for example, as shown in FIG. 5, the scribe line RL may be provided with a plurality of V-shaped scribe lines RL. When the distance from the crease line BL to the apex of the scribe line RL is the same, and compared with the first embodiment, in the example shown in Fig. 5, the predetermined angle α is larger than that of the first embodiment. In addition, when the distance from the vertices of the fold line BL to the scribe line RL is the same as that of the first modification of the first embodiment, in the example (variation 2) shown in FIG. 5, there are two The same V-shaped scribe line RL of the modification 1 is used. As a result, a larger tension can be applied to the inside of the end portion 2 and the bent portion 4.

<Other Modifications>

Further, the scribe line RL may be provided on the end portion 2 side. When the scribe line RL is provided on the side of the bent portion 4, the end portion 2 and the bent portion 4 are curved so as to expand the side of the bent portion 4. On the other hand, when the scribe line RL is provided on the end portion 2 side, the end portion 2 and the bent portion 4 are curved so as to expand the end portion 2 side (the side of the bent portion 4 is recessed). In other words, depending on the position at which the scribe line RL is provided, the direction in which the end portion is expanded (the direction of the recess) can be determined. Therefore, the position where the scribe line RL is provided can be appropriately changed according to the use.

<Second embodiment>

Next, the case where the end structure 1 of the paper product of the first embodiment is applied to a paper package will be described. The object to be accommodated in the package is not particularly limited, but a case in which a tobacco product such as a filter cigarette or a two-cut cigarette is housed in a package will be described as an example. In addition, the material, the shape, the relative arrangement, and the like of the constituent elements described in the present embodiment are not limited to the specific materials, shapes, and relative arrangements unless otherwise specified.
