The hinge lead package has a problem in that a paper sheet is common, and in a paper-made hinge lead package, a warp of the paper is caused and a gap is formed between the cover and the main body. In order to solve such a problem, a technique of preventing the occurrence of a gap by fitting a part of the lid and the main body has been proposed. However, in such a conventional technique, it is concerned that the structure of the package becomes complicated. In addition, deterioration of the paper at the point of attachment by repeatedly fitting is also a concern. Further, this problem is not limited to the hinge lead package, but can be said about the paper product as a whole including the slide-type package having the inner box and the outer box. In particular, at the end portion of a paper product, there is a fear of bending or deterioration.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a technique for suppressing warping and deterioration of an end portion of a paper product.

In order to solve the above problems, the present invention is directed to bending an end portion of a paper product and studying a bending method so that a bending portion is given a tensile force in advance.

In particular, the present invention relates to an end structure of a paper product, comprising: an end of the paper product; a bending portion which is connected to the end portion and is bent toward the end portion and is adhered to the end portion; A folding line provided on a boundary of the folding line and bent in a straight line; a folding line provided in the vicinity of the folding line and at the end or the folding line, the folding line being bent at a distance from the folding line; And the end portion or the bent portion is folded.

The end structure of the paper product of the present invention is characterized in that it has a ruled line in addition to a folding line. The ruled line is for easy bending of a paper product, such as a general ruled line, and can be constituted by a folded portion, a sewing portion, and a thin wall. Although the paper product is originally bent at the ruled line position, the end structure of the paper product of the present invention can be bent at a folding line separate from the ruled line in spite of having the ruled line for bending. Here, when the paper product is bent, a restoring force to return to the original position acts at the folded position. In the end structure of the paper product according to the present invention, in addition to the folded portion being folded at the folding line, the folded portion is folded at the ruled line, and the restoring force is also applied to the ruled line. The ruled line is formed such that the distance from the folding line changes. Thus, for example, as compared with the case where the ruled line is formed in a straight line parallel to the folding line, it is difficult to bend the ruled line. Therefore, when the paper product is bent at the straight line folding line, the paper is warped and bent at the ruled line, so that stronger restoring force acts. Furthermore, the bent portion is adhered to the end portion. As a result, at the end portion of the paper product, a stronger restoring force than the conventional one acts, but it can not return to its original state. Therefore, in the end structure of the paper product of the present invention, a tensile force acts on the inside of the end portion of the paper product, and the end portion of the paper product is prevented from bending. That is, in the end structure of the paper product of the present invention, by controlling the tensile force, that is, by controlling the warpage, the warp of the paper due to the deterioration of performance over time is suppressed. Further, the end structure of the paper product of the present invention is a double structure in which the bent portion is folded, and since it is a simpler structure, it is difficult to deteriorate.

The ruled line can be a V-shaped shape in which the distance from the folding line becomes longer and shorter again. Although it is merely an example of a ruled line, it is easy to process a ruled line and the adjustment of a tensile force is facilitated by making the ruled line a V-shaped. The ruled line may be a straight line or a curved line. The ruled line position of the V character may be provided over the whole of the folding line, or may be provided at a part of the folding line (for example, the central portion or the end portion). The number of V characters may be one or plural. In other words, the ruled line may be configured to have a plurality of V-shaped characters. By providing a plurality of V-shaped elements, a stronger tensile force can be applied. The ruled line may be provided on either the end side or the bending side of the paper product, but it is more preferable to provide the ruled line on the bending side. By providing a ruled line on the bending side, the direction of the restoring force between the folding line and the ruled line coincides with each other, so that a stronger tensile force can be applied.

Here, the ruled line may extend from both ends of the folding line on the straight line and form a predetermined angle with the folding line. The present invention is an example in which base ends of two lines constituting a V-character are provided at both ends of a folding line. By extending the ruled line of the V-shape from the both ends of the folding line, the ruled line comes close to the folding line in the vicinity of both ends of the folding line, and the distance from the folding line gradually increases toward the center. Therefore, even when the paper product is bent at the ruled line, it becomes less conspicuous, and it is possible to reduce a change in the shape of the paper product by providing ruled lines. If the predetermined angle is increased, it is difficult to bend in the ruled line, so that the tensile force becomes large. On the other hand, if the predetermined angle is made smaller, it is easy to bend in the ruled line, so that the tensile force is reduced. Further, if the predetermined angle is increased, the thickness of the end portion increases, so that the shape of the paper product is changed, which may affect the paper product. On the other hand, by reducing the predetermined angle, a change in the shape of the paper product can be reduced. Therefore, the predetermined angle can be designed in consideration of the tensile force and the shape change of the paper product. The ruled line may be a straight line or a curved line. When the ruled line is a curved line, the angle formed by the ruled line and the folding line may be an angle formed by the tangent line of the ruled line in the curve and the folding line in the straight line.

The predetermined angle may be 0.1 to 5.0 degrees. Preferably, the predetermined angle may be 0.2 to 2.0 degrees. More preferably, the predetermined angle may be 0.5 to 1.0 degrees. As a result, a sufficient tensile force can be exerted, and a change in shape of the paper product can be suppressed.

The bent portion may be bonded to the end portion of the bent portion. By adhering the tip end with the greatest restoring force, the tensile force can be effectively applied. The bent portion may be entirely adhered to its end portion.

The ruled line may be different in tensile force acting on the inside of the end portion of the paper product in the case where the ruled line is provided at the end portion and in the case where the ruled line is provided at the bent portion. When the ruled line is provided at the end portion, the end portion structure of the paper product can be inflated at the end portion side. On the other hand, when a ruled line is provided on the bending portion, the end structure of the paper product can inflate the bending portion side (concave the end portion). That is, the direction (concave direction) in which the end structure is inflated can be determined by the position where the ruled line is provided. Therefore, the position provided by the ruled line can be appropriately changed depending on the use of the paper product.

Here, the present invention can be specified as a package having an end structure of the paper product. For example, the present invention is a package made of paper, comprising: an end portion forming at least a part of an opening edge of the package; a bending portion extending from the end portion and bent toward the end portion, A folding line provided at a boundary between the end portion and the bent portion and formed by a straight line bent at the folded portion and a folded line provided in the vicinity of the folded line and at the end or the folded portion, And a ruled line in which the end portion or the bent portion is bent when the bent portion is bent.

In the package made of paper according to the present invention, tensile force acts inside the end portion forming at least a part of the opening edge of the package made of paper. Therefore, in the opening of the package, warping due to deterioration in performance over time is suppressed. Therefore, for example, when the package is constituted by the lid portion and the accommodating portion, a gap is not easily generated between the lid portion and the accommodating portion. Further, the package made of paper of the present invention has a double structure in which the bent portion is folded, so that the package has a simpler structure, so that the opening of the package is less likely to deteriorate.

The package made of paper may be, for example, a package including a substantially rectangular parallelepiped-shaped housing portion having an opening for housing the object to be held and a lid portion at least covering the opening. In such a package, the end structure of the present invention can be used for an end portion of the lid portion, for example, an upper wall of the lid portion or an end portion of the front wall of the lid portion. Further, the end structure of the present invention may be used at the end of the opening of the accommodating portion. Specifically, the present invention is a package made of paper including a substantially rectangular parallelepiped-shaped housing portion having an opening for housing an object to be contained and a lid portion at least covering the opening, wherein the end portion of the lid portion And a bent portion which is connected to at least one of the ends of the opening of the receiving portion and is bent toward the inside of the package and bonded to the end portion of the package and a bending portion provided at a boundary between the end portion and the bending portion, A folding line on a straight line which is further bent and a ruled line which is provided in the vicinity of the folding line and at the end or the folding line and in which the distance from the folding line changes, And is a package made of paper having a folded ruled line. By bending the bent portion to the inside of the package, an inward pulling force acts on the end of the lid portion and the end portion of the opening of the receiving portion. As a result, a gap is less likely to occur between the lid portion and the accommodating portion.

Further, the paper-made package includes, for example, an inner box having an opening for receiving the object to be received and an object to be taken therefrom, and an outer box having an inlet and an outlet for receiving and receiving the inner box Package. In this package, the end structure of the present invention can be used at the end of the opening of the inner box. Further, the end structure of the present invention may be used at an end portion of a cash-box of the outer box. More specifically, the present invention relates to a package made of paper, comprising an inner box having an opening for receiving an object to be received and for taking out an object to be received, and an outer box having an inner box for accommodating the inner box, A bent portion which is connected to at least one of end portions of an opening of the inner box and an end portion of an outlet port of the outer box and is bent inside the package and bonded to the end portion; A folding line provided on a boundary between the folding line and the folding line so as to fold the folding line; a ruling line provided in the vicinity of the folding line and at the end or the folding line, And the folded portion is folded when the additional folded portion is folded. By bending the bent portion to the inside of the package, a tensile force acting inward is applied to the end of the opening of the inner box and the end of the cashbox of the outer box. As a result, a clearance between the inner box and the outer box becomes less likely to occur.

The paper package to which the end structure of the paper product of the present invention is applied is not limited to the above-described substrate. The end structure of the paper product of the present invention can be widely used as an end portion of a package made of paper, which can be bent at the end of a package made of paper. In the package, the tensile force is applied to the inside of the package, but the tensile force may act outside the package depending on the application. For example, in the package having the lid portion having the front wall and the receiving portion having the front wall partially overlapping the front wall of the lid portion, an end structure in which the tensile force acts on the outer side of the package can be used at the end portion of the front wall of the receiving portion . As a result, the resistance between the front wall of the container and the front wall of the lid portion is increased, and the lid closing is improved.

Further, the present invention may be specified as the blank of the paper package. For example, the present invention is a blank for a package made of paper, comprising: a substantially rectangular parallelepiped-shaped receiving portion for receiving an object to be contained and having an opening for taking an object to be held; and a lid portion at least covering the opening, And at least one of an end portion of the lid panel and an end portion of the receiving panel, which is composed of a member separate from the lid panel and constitutes the receiving portion, A reinforcement panel which is connected to an end of either one of the lid panel and the receiving panel and is bent inside the package and adhered to at least one panel of the lid panel and the receiving panel; A folding line provided on a boundary with the reinforcing panel and having a straight line in which the reinforcing panel is bent and a vicinity of the folding line, Is a ruled line provided on either one of the accommodation panel and the reinforcing panel and the distance from the folding line is changed. When the reinforcing panel is bent, the lid panel or the receiving panel and the reinforcing panel Is a blank of a package made of paper having a folded ruled line.

Further, for example, the present invention provides a paper making apparatus comprising: an inner box having an opening for receiving an object to be received and for taking out an object to be received; and an outer box having an inner box for accommodating the inner box, An inner box panel constituting the inner box and an outer box panel constituted by a member different from the inner box panel and constituting the outer box part; and an end part of the inner box panel, A reinforcing panel extending from at least one of the ends of the box panel to the inside of the package and being bonded to at least one of the inner box panel and the outer box panel, Or an end portion of the outer box panel and a folding portion provided on a boundary between the reinforcing panel and a straight line folding the reinforcing panel And a reinforcing panel provided on one of the inner box panel, the outer box panel and the reinforcing panel in the vicinity of the folding line, wherein the reinforcing panel is bent with a ruled line varying in distance from the folding line , The inner box panel or the outer box panel, and the reinforcing panel.

The material to be received in the receiving portion of the paper-made package is not particularly limited, but a collection of the bar-shaped articles, for example, a cigarette product can be suitably exemplified as the material to be received. That is, the object of the present invention may be a cigarette product. Examples of the tobacco product include tobacco cigarettes (filter cigarettes, tobacco cigarettes (no filter), cigars, cigarillos, snus, tobacco, chewing tobacco, and electronic cigarettes.

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

According to the present invention, it is possible to provide a technique for suppressing warping and deterioration of an end portion of a paper product.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of an end structure of a paper product of the present invention will be described with reference to the drawings.

<Preparation process>

Fig. 1 shows a step of making an end structure of a paper product according to the first embodiment. 1 (a-1) to (a-4) on the left side of Fig. 1 show plan views of the end portion of the paper product. (B-1) to (b-4) on the right side of Fig. 1 show flat sectional views of end portions of the paper product.

In the preparation of the end structure of the paper product of the first embodiment, first, the ruled line RL is processed with respect to the paper product. As shown in Figs. 1 (a-1) and 1 (b-1), the end structure 1 of the paper product of the first embodiment is connected to the end portion 2 and the end portion 2 of the paper product, A bending portion 4 that is bent toward the back portion 2 and bonded to the pasted portion 3 of the end portion 2 and a bent portion 4 that is provided at the boundary between the end portion 2 and the bending portion 4, The bent line RL is formed in the vicinity of the fold line BL and the fold line BL on the straight line and in the V-shaped ruled line RL provided in the bent section 4 and changing the distance from the fold line BL, Has a ruled line RL that is bent when bent.

Fig. 2 is an enlarged plan view of the end structure of the paper product of the first embodiment before bending. The end structure 1 of the paper product of the first embodiment is characterized in that it has a V-shaped ruled line RL near the straight fold line BL. The ruled line RL is intended to make it easier to bend the paper product, such as a general ruled line. The ruled line RL can be composed of a folded portion, a sewing portion, and a thin wall. Examples of the processing of the ruled line RL include conventional processing techniques, processing by a plotter, and processing by embossing.

The ruled line RL of the first embodiment is formed such that two straight lines forming a V-letter form a straight line extending from both ends of a folding line BL and form a predetermined angle alpha with the folding line BL. In the first embodiment, the predetermined angle alpha is 1 degree. The predetermined angle alpha is not limited to this angle. The predetermined angle? May be 0.1 to 5.0 degrees. Preferably, the predetermined angle alpha may be 0.2 to 2.0 degrees. More preferably, the predetermined angle alpha may be 0.5 to 1.0 degrees. If the predetermined angle? Is increased, the bending of the ruled line RL becomes difficult, and therefore the tensile force becomes large. On the other hand, if the predetermined angle? Is made smaller, the ruled line RL is easily bent and the tensile force is reduced. Further, if the predetermined angle? Is increased, the thickness of the end portion increases, and the shape of the paper product changes, which may affect the paper product. On the other hand, by reducing the predetermined angle?, It is possible to reduce the change in the shape of the paper product. Therefore, the predetermined angle alpha can be designed in consideration of the tensile force and the shape change of the paper product. The ruled line RL may be curved.

Returning to the description of Fig. As shown in Figs. 1 (a-2), (a-3), 1 (b-2) and 3 (b-3), in the preparation of the end structure 1 of the paper product of the first embodiment, , And is bent at a folding line BL in a straight line. In the end structure 1 of the paper product of the first embodiment, in addition to the folded portion 4 being folded at the fold line BL, the folded portion 4 is bent also in the V-shaped ruled line RL. Therefore, the vicinity of the fold line BL and the ruled line RL becomes slightly V-shaped as shown in Fig. 1 (a-3). The drawing is emphatically shown. When the predetermined angle? Is 1 degree, the vicinity of the fold line BL and the ruled line RL is substantially straight. The same is true for the other drawings.

In the preparation of the end part structure 1 of the paper product of the first embodiment as shown in Figs. 1 (a-4) and 1 (b-4), the folded part 4, (3). In the first embodiment, the leading end of the bent portion 4 is adhered. By adhering the tip end with the greatest restoring force, the tensile force can be effectively applied. The bent portion 4 may be entirely adhered to the end portion 2. Thus, the end structure 1 of the paper product of the first embodiment is completed.

<Configuration>

Fig. 3A shows a plan view of an end structure of the paper product of the first embodiment. Fig. Fig. 3B shows a cross-sectional view along the line A-A in Fig. 3A. 3C is a sectional view taken along the line B-B in Fig. 3A. The end structure 1 of the paper product of the first embodiment is folded at the straight line fold line BL and the ruled line RL and the end portion 2 and the bent portion 4 are folded and folded to form a double structure. The end portion 2 and the bent portion 4 are curved so that the bent portion 4 side is swollen.

&Lt; Action &gt;

In the end structure 1 of the paper product of the first embodiment, the paper product is originally bent at the ruled line position, but it is bent at the fold line BL different from the ruled line RL. Here, when the paper product is bent, a restoring force to return to the original position acts at the folded position. In the end portion structure 1 of the paper product of the first embodiment, the folded portion 4 is bent at the fold line BL and also folded at the folded line RL, . The ruled line RL is formed in a V-shape so as to change the distance from the fold line BL. Therefore, for example, as compared with the case where the ruled line RL is formed in a straight line parallel to the folding line, the ruled line RL having the V-shaped shape is difficult to bend. Therefore, when the paper product is bent at the straight line folding line BL, stronger restoring force acts because it is bent while being resistant to the ruled line RL. Furthermore, the bent portion 4 is adhered to the end portion 2. As a result, in the end portion 2 of the paper product, a stronger restoring force acts than in the past, but it can not return to its original state. Therefore, in the end structure 1 of the paper product of the first embodiment, a tensile force is applied so that the folded portion 4 is swollen inside the end portion 2 and the folded portion 4. As a result, the end portion 2 and the bent portion 4 are bent so that the bent portion 4 side is swollen. In the end structure (1) of the paper product of the first embodiment, tensile force acts beforehand in the end portion (2) and the bent portion (4) The warping can be suppressed. In addition, the end structure 1 of the paper product of the first embodiment is a double structure in which the end portion 2 and the bent portion 4 are folded and overlapped.

By extending the V-shaped ruled line RL from both ends of the fold line BL, the ruled line RL is close to the fold line BL in the vicinity of both ends of the fold line BL, (BL) gradually becomes longer. Therefore, even when the paper product is bent at the ruled line RL, it becomes less conspicuous, and it is possible to reduce a change in the shape of the paper product by providing the ruled line RL.

&Lt; Modification Example 1 &

The end structure 1 of the paper product of the first embodiment is merely an example. For example, as shown in FIG. 4, the ruled line RL may be provided with a V-shaped ruled line RL at the center of the folding line BL. In the example shown in Fig. 4 (Modification 1), the predetermined angle alpha is set to be equal to or larger than the distance from the fold line BL to the apex of the ruled line RL, It grows. As a result, a larger tensile force can be applied to the inside of the end portion 2 and the bent portion 4.

&Lt; Modification Example 2 &

For example, as shown in FIG. 5, a plurality of ruled lines RL may be provided in the V-shaped ruled lines RL. In the example shown in Fig. 5, the predetermined angle alpha is larger than that in the first embodiment, with the same distance from the fold line BL to the apex of the ruled line RL. Compared with the first modified example of the first embodiment in which the distance from the fold line BL to the apex of the ruled line RL is the same, in the example shown in Fig. 5 (modified example 2) There are two V-shaped ruled lines RL. As a result, a large tensile force can be exerted by the inside of the end portion (2) and the bent portion (4).

<Other Modifications>

The ruled line RL may be provided on the end portion 2 side. When the ruled line RL is provided on the side of the bending portion 4, the end portion 2 and the bending portion 4 are curved as the bending portion 4 side is swollen. On the other hand, when the ruled line RL is provided on the side of the end portion 2, the end portion 2 and the bent portion 4 are bent such that the side of the bent portion 4 is concave do. That is, the direction (concave direction) in which the end portion is swollen can be determined by the position where the ruled line RL is provided. Therefore, the position where the ruled line RL is provided can be appropriately changed according to the use.

&Lt; Second Embodiment &gt;

Next, a case where the end structure 1 of the paper product of the first embodiment is applied to a package made of paper will be described. The material to be contained in the package is not limited to a specific one, but a case where a cigarette product such as a filter cigarette or a tobacco cigarette is accommodated in a package will be described as an example. In addition, the material, shape, relative arrangement, and the like of the constituent elements described in the present embodiment are not intended to limit the technical scope of the invention to such a constituent element unless specifically stated.
