Definitions
- the present invention relates to an end portion structure of a paper product, and a package made of paper.
- a package that houses a housed object such as tobacco products
- a soft pack type package As one form of a hard type package, a hinge lid package (also referred to as a hinge lid box) including a lid is known.
- a hinge lid package of this kind usually has a box-shaped external shape, and a housing portion that houses a cigarette bundle, and a lid for opening and closing an opening end that is formed at an upper portion of the housing portion are turnably connected via a hinge that is provided along an edge portion of the opening end.
- Hinge lid packages are generally made of paper, and in the hinge lid package made of paper, there has been the problem that a gap occurs between a lid and a main body due to deflection of paper.
- an art of preventing occurrence of a gap by fitting a lid and a part of a main body In order to solve the problem like this, there is proposed an art of preventing occurrence of a gap by fitting a lid and a part of a main body.
- complication of the structure of the package is feared.
- deterioration of paper at the fitted spot by being repeatedly fitted is also feared.
- these problems are not limited to hinge lid packages, but can be said of all paper products including slide type packages having inner boxes and outer boxes. In particular, at the end portions of paper products, deflection and deterioration are feared.
- the present invention has an object to provide an art of restraining deflection and deterioration of an end portion of a paper product.
- an end portion of a paper product is bent, and a way of bending is devised, so that a tensile force can be given to a bend portion in advance.
- the present invention is an end portion structure of a paper product, including an end portion of the paper product, a bend portion that connects to the end portion, is bent to a side of the end portion, and is bonded to the end portion, a rectilinear bend line which is provided in a border between the end portion and the bend portion, and in (along) which the bend portion is bent, and a ruled line that is provided in a vicinity of the bend line, and in the end portion or the bend portion, with a distance from the bend line changing, and is the ruled line in which the end portion or the bend portion bends when the bend portion is bent.
- One of features of the end portion structure of a paper product according to the present invention is including the ruled line in addition to the bend line.
- the ruled line is for facilitating bending a paper product similarly to an ordinary ruled line, and can be formed by a fold, perforations, and a thin-walled portion.
- a paper product is originally bent in a ruled line position, but in the end portion structure of a paper product according to the present invention, the paper product is bent in the bend line which is different from the ruled line, contrary to the ruled line, although the end portion structure of a paper product according to the present invention has the ruled line for bending.
- a restoration force to return to an original position acts in the bent position.
- the bend portion is also bent in the ruled line, in addition to being bent in the bend line, and a restoration force also acts in the ruled line.
- the ruled line is formed so that the distance from the bend line changes. Consequently, when compared with a case where the ruled line is formed into a shape of a straight line parallel with the bend line, bending is difficult in the ruled line. Accordingly, when the paper product is bent in the rectilinear bend line, the paper product bends while resisting in the ruled line, and therefore a stronger restoration force acts. Further, the bend portion is bonded to the end portion.
- the bend portion cannot return to the original position, although the restoration force which is stronger than the conventional restoration force acts on the end portion of the paper product. Consequently, in the end portion structure of a paper product according to the present invention, a tensile force acts on an inside of the end portion of a paper product, and the end portion of a paper product is restrained from deflecting. That is, in the end portion structure of a paper product according to the present invention, deflection of paper due to deterioration over time is restrained by controlling the tensile force, in other words, controlling deflection. Further, since in the end portion structure of a paper product according to the present invention, the bend portion is bent to make a double structure, and further the structure is very simple, so that deterioration hardly occurs.
- the ruled line can be formed into a V shape in which the distance from the bend line gradually becomes longer, and becomes shorter again.
- the ruled line may be in a rectilinear shape, or may be in a curved shape.
- a position of the V-shaped ruled line may be provided throughout the entire bend line, or may be provided at a part of the bend line (a central portion, or an end portion, for example).
- the number of V-shapes may be one, or may be more than one.
- the ruled line may be of a structure having a plurality of the V-shapes.
- a vertex of the V-shape may be provided at either the end portion side or the bend portion side of the paper product, but is more preferably provided at the bend portion side.
- the ruled line may extend from both end portions of the rectilinear bend line, and may form a predetermined angle with the bend line.
- the present invention is an example in which base ends of two lines forming the V-shape are provided at both the end portions of the bend line.
- the predetermined angle can be designed with the tensile force, and the change of the shape of the paper product taken into consideration.
- the ruled line may be in a rectilinear shape or may be in a curved shape.
- the angle formed by the ruled line and the bend line can be made an angle formed by a tangential line of the ruled line in a curved shape and the bend line in a rectilinear shape.
- the predetermined angle can be made 0.1 degrees to 5.0 degrees.
- the predetermined angle can be preferably made 0.2 degrees to 2.0 degrees.
- the predetermined angle can be more preferably made 0.5 degrees to 1.0 degree. Thereby, a sufficient tensile force can be caused to act, and the change of the shape of the paper product can be restrained.
- a distal end portion may be bonded to the end portion.
- the tensile force can be effectively caused to act.
- the bend portion may be entirely bonded to the end portion.
- tensile forces that act on an inside of the end portion of the paper product can be caused to differ between a case where the ruled line is provided in the end portion, and a case where the ruled line is provided in the bend portion.
- the end portion side can be expanded in the end portion structure of a paper product.
- the bend portion side can be expanded (the end portion side is recessed) in the end portion structure of a paper product. That is, a direction to expand (a direction to recess) the end portion structure can be determined depending on a position where the ruled line is provided. Accordingly, the position where the ruled line is provided can be properly changed in accordance with a use purpose of the paper product.
- the present invention can be defined as the package having the end portion structure of a paper product described above.
- the present invention is a package made of paper, including an end portion that forms at least a part of an opening edge of the package of paper, a bend portion that connects to the end portion, is bent to a side of the end portion, and is bonded to the end portion, a rectilinear bend line that is provided in a border between the end portion and the bend portion, and in (along) which the bend portion is bent, and a ruled line that is provided in a vicinity of the bend line, and in the end portion or the bend portion, with a distance from the bend line changing, and is the ruled line in which the end portion or the bend portion bends when the bend portion is bent.
- a tensile force acts on an inside of the end portion that forms at least a part of the opening edge of the package made of paper. Consequently, deflection due to deterioration over time in the opening of the package can be restrained. Accordingly, when the package is formed by the lid unit and the housing unit, a gap hardly occurs between the lid unit and the housing unit. Further, in the package made of paper according to the present invention, the bend portion is bent to make a double structure, and further, the structure is very simple, so that the opening of the package is hardly deteriorated.
- the package made of paper can be made a package including a housing portion in a substantially rectangular parallelepiped shape that houses a housed object and has an opening from which the housed object is taken out, and a lid unit that covers at least the opening.

- the paper product is bent in the bend line BL which is different from the ruled line RL, in the end portion structure 1 of a paper product according to the first embodiment.
- a restoration force to return to the original position acts in the bent position.
- the bend portion 4 is also bent in the ruled line RL, in addition to being bent in the bend line BL, and a restoration force also acts in the ruled line RL.
- the ruled line RL is formed into the V-shape so that the distance from the bend line BL changes.
- the V-shaped ruled line RL is difficult to bend. Accordingly, when the paper product is bent in the rectilinear bend line BL, the paper product is bent while resisting in the ruled line RL, and therefore a stronger restoration force acts. Further, the bend portion 4 is bonded to the end portion 2. As a result, the bend portion cannot return to the original position, although the restoration force which is stronger than the conventional restoration force acts on the end portion 2 of the paper product.

Japanese Patent Laid-Open No. 2011-68411 - Hinge lid packages are generally made of paper, and in the hinge lid package made of paper, there has been the problem that a gap occurs between a lid and a main body due to deflection of paper. In order to solve the problem like this, there is proposed an art of preventing occurrence of a gap by fitting a lid and a part of a main body. However, in the conventional art like this, complication of the structure of the package is feared. Further, deterioration of paper at the fitted spot by being repeatedly fitted is also feared. Note that these problems are not limited to hinge lid packages, but can be said of all paper products including slide type packages having inner boxes and outer boxes. In particular, at the end portions of paper products, deflection and deterioration are feared.
- In the light of the above described problems, the present invention has an object to provide an art of restraining deflection and deterioration of an end portion of a paper product.
- In the present invention, in order to solve the aforementioned problems, an end portion of a paper product is bent, and a way of bending is devised, so that a tensile force can be given to a bend portion in advance.
- In more detail, the present invention is an end portion structure of a paper product, including an end portion of the paper product, a bend portion that connects to the end portion, is bent to a side of the end portion, and is bonded to the end portion, a rectilinear bend line which is provided in a border between the end portion and the bend portion, and in (along) which the bend portion is bent, and a ruled line that is provided in a vicinity of the bend line, and in the end portion or the bend portion, with a distance from the bend line changing, and is the ruled line in which the end portion or the bend portion bends when the bend portion is bent.
- One of features of the end portion structure of a paper product according to the present invention is including the ruled line in addition to the bend line. The ruled line is for facilitating bending a paper product similarly to an ordinary ruled line, and can be formed by a fold, perforations, and a thin-walled portion. A paper product is originally bent in a ruled line position, but in the end portion structure of a paper product according to the present invention, the paper product is bent in the bend line which is different from the ruled line, contrary to the ruled line, although the end portion structure of a paper product according to the present invention has the ruled line for bending. Here, when the paper product is bent, a restoration force to return to an original position acts in the bent position. In the end portion structure of a paper product according to the present invention, the bend portion is also bent in the ruled line, in addition to being bent in the bend line, and a restoration force also acts in the ruled line. Further, the ruled line is formed so that the distance from the bend line changes. Consequently, when compared with a case where the ruled line is formed into a shape of a straight line parallel with the bend line, bending is difficult in the ruled line. Accordingly, when the paper product is bent in the rectilinear bend line, the paper product bends while resisting in the ruled line, and therefore a stronger restoration force acts. Further, the bend portion is bonded to the end portion. As a result, the bend portion cannot return to the original position, although the restoration force which is stronger than the conventional restoration force acts on the end portion of the paper product. Consequently, in the end portion structure of a paper product according to the present invention, a tensile force acts on an inside of the end portion of a paper product, and the end portion of a paper product is restrained from deflecting. That is, in the end portion structure of a paper product according to the present invention, deflection of paper due to deterioration over time is restrained by controlling the tensile force, in other words, controlling deflection. Further, since in the end portion structure of a paper product according to the present invention, the bend portion is bent to make a double structure, and further the structure is very simple, so that deterioration hardly occurs.
- The ruled line can be formed into a V shape in which the distance from the bend line gradually becomes longer, and becomes shorter again. By forming the ruled line into the V-shape, though it is only an example of the ruled line, work of the ruled line is facilitated, and adjustment of the tensile force is easily performed. The ruled line may be in a rectilinear shape, or may be in a curved shape. A position of the V-shaped ruled line may be provided throughout the entire bend line, or may be provided at a part of the bend line (a central portion, or an end portion, for example). The number of V-shapes may be one, or may be more than one. In other words, the ruled line may be of a structure having a plurality of the V-shapes. By providing the plurality of V-shapes, a stronger tensile force can be caused to act. In the ruled line, a vertex of the V-shape may be provided at either the end portion side or the bend portion side of the paper product, but is more preferably provided at the bend portion side. By providing the ruled line at the bend portion side, directions of restoration forces of the bend line and the ruled line correspond to each other, and a stronger tensile force can be caused to act.
- Here, the ruled line may extend from both end portions of the rectilinear bend line, and may form a predetermined angle with the bend line. The present invention is an example in which base ends of two lines forming the V-shape are provided at both the end portions of the bend line. By extending the V-shaped ruled line from both the end portions of the bend line, the ruled line is close to the bend line in vicinities of both the end portions of the bend line, and the distance from the bend line gradually becomes longer toward the center. Consequently, when the paper product bends in the ruled line, it is hardly noticeable, and a change of the shape of the paper product by providing the ruled line can be decreased. When the predetermined angle is made large, bending becomes difficult in the ruled line, and therefore the tensile force increases. When the predetermined angle is made small, bending becomes easy in the ruled line, and the tensile force decreases. Further, when the predetermined angle is made large, the thickness of the end portion increases, the shape of the paper product changes, and the influence on the paper product is feared. By making the predetermined angle small, the change of the shape of the paper product can be decreased. Accordingly, the predetermined angle can be designed with the tensile force, and the change of the shape of the paper product taken into consideration. The ruled line may be in a rectilinear shape or may be in a curved shape. When the ruled line is in a curved shape, the angle formed by the ruled line and the bend line can be made an angle formed by a tangential line of the ruled line in a curved shape and the bend line in a rectilinear shape.
- Further, the predetermined angle can be made 0.1 degrees to 5.0 degrees. The predetermined angle can be preferably made 0.2 degrees to 2.0 degrees. The predetermined angle can be more preferably made 0.5 degrees to 1.0 degree. Thereby, a sufficient tensile force can be caused to act, and the change of the shape of the paper product can be restrained.
- Further, in the bend portion, a distal end portion may be bonded to the end portion. By bonding the distal end portion on which the restoration force acts most significantly, the tensile force can be effectively caused to act. The bend portion may be entirely bonded to the end portion.
- Further, tensile forces that act on an inside of the end portion of the paper product can be caused to differ between a case where the ruled line is provided in the end portion, and a case where the ruled line is provided in the bend portion. When the ruled line is provided in the end portion, the end portion side can be expanded in the end portion structure of a paper product. When the ruled line is provided in the bend portion, the bend portion side can be expanded (the end portion side is recessed) in the end portion structure of a paper product. That is, a direction to expand (a direction to recess) the end portion structure can be determined depending on a position where the ruled line is provided. Accordingly, the position where the ruled line is provided can be properly changed in accordance with a use purpose of the paper product.
- Here, the present invention can be defined as the package having the end portion structure of a paper product described above. For example, the present invention is a package made of paper, including an end portion that forms at least a part of an opening edge of the package of paper, a bend portion that connects to the end portion, is bent to a side of the end portion, and is bonded to the end portion, a rectilinear bend line that is provided in a border between the end portion and the bend portion, and in (along) which the bend portion is bent, and a ruled line that is provided in a vicinity of the bend line, and in the end portion or the bend portion, with a distance from the bend line changing, and is the ruled line in which the end portion or the bend portion bends when the bend portion is bent.
- In the package made of paper according to the present invention, a tensile force acts on an inside of the end portion that forms at least a part of the opening edge of the package made of paper. Consequently, deflection due to deterioration over time in the opening of the package can be restrained. Accordingly, when the package is formed by the lid unit and the housing unit, a gap hardly occurs between the lid unit and the housing unit. Further, in the package made of paper according to the present invention, the bend portion is bent to make a double structure, and further, the structure is very simple, so that the opening of the package is hardly deteriorated.
- The package made of paper can be made a package including a housing portion in a substantially rectangular parallelepiped shape that houses a housed object and has an opening from which the housed object is taken out, and a lid unit that covers at least the opening. In the package like this, the end portion structure according to the present invention described above can be used in an end portion of the lid unit, for example, an end portion of the top wall of the lid unit or the front wall of the lid unit. Further, the end portion structure according to the aforementioned present invention may be used in the end portion of the opening of the housing unit. More specifically, the present invention is a package made of paper including a housing portion in a substantially rectangular parallelepiped shape that houses a housed object, and has an opening from which the housed object is taken out, and a lid unit that covers at least the opening, and is a package made of paper including a bend portion that connects to at least either one of an end portion of the lid unit and an end portion of the opening of the housing unit, is bent to an inside of the package, and is bonded to the end portion, a rectilinear bend line that is provided in a border between the end portion and the bend portion, and in (along) which the bend portion is bent, and a ruled line that is provided in a vicinity of the bend line, and in the end portion or the bend portion, with a distance from the bend line changing, and is the ruled line in which the end portion or the bend portion bends when the bend portion is bent. By bending the bend portion to the inside of the package, a tensile force toward the inside acts on the end portion of the lid unit and the end portion of the opening of the housing portion. As a result, a gap hardly occurs between the lid unit and the housing unit.
- Further, the package made of paper can be made, for example, a package including an inner box that houses a housed object and has an opening from which the housed object is taken out, and an outer box that houses the inner box, and has a putting-in-and-taking-out port through which the inner box is put in and taken out. In the package like this, the end portion structure according to the present invention described above may be used in the end portion of the opening of the inner box. Further, the end portion structure according to the present invention described above may be used in the end portion of the putting-in-and-taking-out port of the outer box. More specifically, the present invention is a package made of paper including an inner box that houses a housed object, and has an opening from which the housed object is taken out, and an outer box that houses the inner box, and has a putting-in-and-taking-out port through which the inner box is put in and taken out, and is a package made of paper including a bend portion that connects to at least either one of an end portion of the opening of the inner box and an end portion of the putting-in-and-taking-out port of the outer box, is bent to an inside of the package, and is bonded to the end portion, a rectilinear bend line that is provided in a border between the end portion and the bend portion, and in (along) which the bend portion is bent, and a ruled line that is provided in a vicinity of the bend line, and in the end portion or the bend portion, with a distance from the bend line changing, and is the ruled line in which the end portion or the bend portion bends when the bend portion is bent. By bending the bend portion to the inside of the package, a tensile force toward the inside acts on the end portion of the opening of the inner box and the end portion of the putting-in-and-taking-out port of the outer box. As a result, a gap hardly occurs between the inner box and the outer box.
- Note that the package made of paper to which the end portion structure of a paper product of the present invention is applied is not limited to what is described above. The end portion structure of a paper product of the present invention can be widely used in the end portion of a package made of paper that is an end portion of a package made of paper that can be bent. In the aforementioned package, a tensile force is caused to act on the inside of the package, but a tensile force can be also caused to act on an outside of the package in accordance with a use purpose. For example, in a package including a lid unit having a front wall, and a housing unit having a front wall that partially overlaps the front wall of the lid unit, an end portion structure that causes a tensile force to act on the outside of the package can be used in an end portion of the front wall of the housing unit. Thereby, the resistance between the front wall of the housing object and the front wall of the lid unit increases, and lid closure is enhanced.
- Further, the present invention can be also defined as a blank of the package made of paper described above. For example, the present invention is a blank of a package made of paper including a housing unit in a substantially rectangular parallelepiped shape that houses a housed object, and has an opening from which the housed object is taken out, and a lid unit that covers at least the opening, and is a blank of a package made of paper including a lid panel forming the lid unit, a housing panel that connects to the lid panel, or formed of a separate member from the lid panel, and forms the housing unit, a reinforcement panel that connects to at least either one end portion of an end portion of the lid panel and an end portion of the housing panel, is bent to an inside of the package, and is bonded to at least either one panel of the lid panel and the housing panel, a rectilinear bend line that is provided in a border of the end portion of the lid panel or the end portion of the housing panel, and the reinforcement panel, and in which the reinforcement panel is bent, and a ruled line that is provided in a vicinity of the bend line, and in at least one of the lid panel or the housing panel, and the reinforcement panel, with a distance from the bend line changing, and is the ruled line in which one of the lid panel or the housing penal and the reinforcement panel bends when the reinforcement panel is bent.
- Further, for example, the present invention is a blank of a package made of paper including an inner box that houses a housed object, and has an opening from which the housed object is taken out, and an outer box that houses the inner box and has a putting-in-and-taking-out port through which the inner box is put in and taken out, and is the blank of the package made of paper including an inner box panel forming the inner box, an outer box panel that is formed of a separate member from the inner box panel, and forms the outer box unit, a reinforcement panel that connects to at least either one end portion of an end portion of the inner box panel and an end portion of the outer box panel, is bent to an inside of the package, and is bonded to at least either one panel of the inner box panel and the outer box panel, a rectilinear bend line that is provided in a border between the end portion of the inner box panel or the end portion of the outer box panel, and the reinforcement panel, and in which the reinforcement panel is bent, and a ruled line that is provided in a vicinity of the bend line, and in one of the inner box panel or the outer box panel, and the reinforcement panel, with a distance from the bend line changing, and is the ruled line in which one of the inner box panel or the outer box panel, and the reinforcement panel bends when the reinforcement panel is bent.
- Although the housed object that is housed in the housing unit of the package made of paper is not specially limited, an aggregate of bar-shaped articles, for example, a tobacco product can be preferably illustrated as the housed object. That is, the housed object according to the present invention may be a tobacco product. Note that the tobacco products may include, for example, cigarettes (filter cigarettes, plain cigarettes (no filter)), cigars (rolled in dried tobacco leaf), cigarillos, snus, snuff, chewing tobacco, electronic cigarettes and others.

-
Fig. 1 illustrates a production process of an end portion structure of a paper product according to a first embodiment. Reference signs (a-1) to (a-4) at a left side ofFig. 1 illustrate plan views of the end portion of a paper product. Reference signs (b-1) to (b-4) at a right side ofFig. 1 denote plane sectional views of the end portion of a paper product. - In production of the end portion structure of a paper product according to the first embodiment, a ruled line RL is worked for the paper product first. As illustrated in
Fig. 1 (a-1) andFig. 1 (b-1), anend portion structure 1 of a paper product according to the first embodiment includes anend portion 2 of a paper product, a bend portion (a folding portion) 4 that connects to theend portion 2, is bent to a side of theend portion 2, and is bonded to amargin 3 for bonding in theend portion 2, a rectilinear bend line BL which is provided on a border between theend portion 2 and thebend portion 4, and in which thebend portion 4 is bent, and a V-shaped ruled line RL that is provided in a vicinity of the bend line BL, and in thebend portion 4, with a distance from the bend line BL changing, and is the ruled line RL that bends when thebend portion 4 is bent. -
Fig. 2 illustrates an enlarged plan view before bending of the end portion structure of a paper product according to the first embodiment. One of features of theend portion structure 1 of a paper product according to the first embodiment is including the V-shaped ruled line RL in the vicinity of the rectilinear bend line BL. The ruled line RL is for facilitating bending a paper product similarly to an ordinary ruled line. The ruled line RL can be formed by a fold, perforations, and a thin-walled portion. As work of the ruled line RL, an existing working technique, work by a plotter, and work by embossing are illustrated. - In the ruled line RL of the first embodiment, two straight lines forming a V-shape extend from both end portions of the rectilinear bend line BL, and form predetermined angles α with the bend line BL. In the first embodiment, the predetermined angle α is one degree. The predetermined angle α is not limited to this angle. The predetermined angle α can be made 0.1 degrees to 5.0 degrees. The predetermined angle α can be preferably made 0.2 degrees to 2.0 degrees. The predetermined angle α can be more preferably made 0.5 degrees to 1.0 degree. When the predetermined angle α is made large, bending becomes difficult in the ruled line RL, and therefore, a tensile force increases. When the predetermined angle α is made small, bending becomes easy in the ruled line RL, and the tensile force decreases. Further, when the predetermined angle α is made large, a thickness of the end portion increases, and the shape of the paper product changes, whereby an influence on the paper product is feared. By making the predetermined angle α small, change of the shape of the paper product can be decreased. Accordingly, the predetermined angle α can be designed with consideration given to the tensile force and the change of the shape of the paper product. The ruled line RL may be in a curved shape.
- Explanation will return to
Fig. 1 . As illustrated inFig. 1 (a-2) and (a-3) andFig. 1 (b-2) and (b-3), in production of theend portion structure 1 of the paper product according to the first embodiment, thebend portion 4 is bent in the bend line BL next. In theend portion structure 1 of the paper product according to the first embodiment, thebend portion 4 is also bent in the V-shaped ruled line RL in addition to thebend portion 4 being bent in the bend line BL. Consequently, as illustrated inFig. 1 (a-3), a vicinity of the bend line BL and the ruled line RL slightly becomes V-shaped. The drawing illustrates by emphasizing, and when the predetermined angle α is one degree, the vicinity of the bend line BL and the ruled line RL is substantially rectilinear. The same also applies to the other drawings. - As illustrated in
Fig. 1 (a-4) andFig. 1 (b-4), in production of theend portion structure 1 of a paper product according to the first embodiment, thebend portion 4 is bonded to themargin 3 for bonding in theend portion 2 next. In the first embodiment, a distal end portion of thebend portion 4 is bonded. By bonding the distal end portion on which a restoration force acts most significantly, the tensile force can be caused to act effectively. Note that thebend portion 4 may be entirely bonded to theend portion 2. By the above, theend portion structure 1 of a paper product according to the first embodiment is completed. -
Fig. 3A illustrates a plan view of the end portion structure of a paper product according to the first embodiment.Fig. 3B illustrates a sectional view along line A-A inFig. 3A. Fig. 3C illustrates a sectional view along line B-B inFig. 3A . Theend portion structure 1 of the paper product according to the first embodiment is bent in the rectilinear bend line BL, and the ruled line RL, theend portion 2 and thebend portion 4 overlap each other to be in a double structure. Further, theend portion 2 and thebend portion 4 curve in such a manner that thebend portion 4 side expands. - Although a paper product is originally bent in a ruled line position, the paper product is bent in the bend line BL which is different from the ruled line RL, in the
end portion structure 1 of a paper product according to the first embodiment. Here, when the paper product is bent, a restoration force to return to the original position acts in the bent position. In theend portion structure 1 of a paper product according to the first embodiment, thebend portion 4 is also bent in the ruled line RL, in addition to being bent in the bend line BL, and a restoration force also acts in the ruled line RL. Further, the ruled line RL is formed into the V-shape so that the distance from the bend line BL changes. Consequently, as compared with a case where the ruled line RL is formed into a rectilinear shape parallel with the bend line, the V-shaped ruled line RL is difficult to bend. Accordingly, when the paper product is bent in the rectilinear bend line BL, the paper product is bent while resisting in the ruled line RL, and therefore a stronger restoration force acts. Further, thebend portion 4 is bonded to theend portion 2. As a result, the bend portion cannot return to the original position, although the restoration force which is stronger than the conventional restoration force acts on theend portion 2 of the paper product. Consequently, in theend portion structure 1 of the paper product according to the first embodiment, a tensile force acts on an inside of theend portion 2 and thebend portion 4 so that thebend portion 4 side expands. As a result, theend portion 2 and thebend portion 4 curve so that thebend portion 4 side expands. Since in theend portion structure 1 of a paper product according to the first embodiment, the tensile force acts on the inside of theend portion 2 and thebend portion 4 in advance, deflection of paper due to deterioration over time can be restrained. Further, since theend portion structure 1 of a paper product according to the first embodiment is a double structure with theend portion 2 and thebend portion 4 overlapping each other, and further is a very simple structure, and therefore, is difficult to deteriorate. - Further, by extending the V-shaped ruled line RL from both end portions of the bend line BL, the ruled line RL is close to the bend line BL in vicinities of both end portions of the bend line BL, and the distance from the bend line BL becomes gradually longer toward a center. Consequently, when the paper product is bent in the ruled line RL, it is not inconspicuous, and a change in the shape of the paper product by providing the ruled line RL can be decreased.
- The
end portion structure 1 of a paper product according to the first embodiment is only an example. For example, as for the ruled line RL, the V-shaped ruled line RL may be provided in a central portion of the bend line BL, as illustrated inFig. 4 . As being compared with the first embodiment on the assumption that a distance to a vertex of the ruled line RL from the bend line BL is the same, in an example (modification 1) illustrated inFig. 4 , the predetermined angle α is larger than in the first embodiment. As a result, a larger tensile force can be caused to act on an inside of theend portion 2 and thebend portion 4. - Further, for example, as for the ruled line RL, a plurality of V-shaped ruled lines RL may be provided as illustrated in
Fig. 5 . As being compared with the first embodiment on the assumption that distances to vertexes of the ruled lines RL from the bend line BL are the same as in the first embodiment, in an example illustrated inFig. 5 , the predetermined angle α is larger than in the first embodiment. Further, as being compared withmodification 1 of the first embodiment on the assumption that the distances to the vertexes of the ruled lines RL from the bend line BL are the same, in the example (modification 2) illustrated inFig. 5 , the two V-shaped ruled lines RL similar tomodification 1 are present. As a result, a larger tensile force can be caused to act on an inside of theend portion 2 and thebend portion 4. - Note that the ruled line RL may be provided at the
end portion 2 side. When the ruled line RL is provided at thebend portion 4 side, theend portion 2 and thebend portion 4 curve so that thebend portion 4 side expands. When the ruled line RL is provided at theend portion 2 side, theend portion 2 and thebend portion 4 bend so that theend portion 2 side expands (thebend portion 4 side is recessed). That is, a direction to expand (a direction to recess) the end portion can be determined depending on a position where the ruled line RL is provided. Accordingly, the position where the ruled line RL is provided can be properly changed in accordance with a use purpose. - Next, a case where the
end portion structure 1 of a paper product according to the first embodiment is applied to the package made of paper will be described. A housed object that is housed in the package is not limited to a specific matter, however, a case where tobacco products such as filter cigarettes, and plain cigarettes are housed in the package will be described as an example, here. Further, a material, a shape and relative disposition and the like of the components described in the present embodiment are not intended to limit the technical range of the invention to only them unless specific explanation is specially made. -
Fig. 6 illustrates a perspective view of a state where alid 30a of a hinge lid package (hereinafter, simply referred to as "a package") according to the second embodiment is closed, seen from an upper front side.Fig. 7 illustrates a perspective view of a state where the lid of the package according to the second embodiment is opened, seen from the upper front side.Fig. 8 illustrates a plan view of the state in which the lid of the package according to the second embodiment is closed, seen from above. - A
package 10a according to the second embodiment is a so-called box type package with a hinge lid having a substantially rectangular parallelepiped shape. Thepackage 10a is formed by including a packagemain body 20a as a housing portion, and alid 30a as a lid member that is rotatably connected to the packagemain body 20a via a hinge H. Hereinafter, in the present specification, a front surface side of thepackage 10a will be defined as "a front side", and a rear surface side will be defined as "a rear side", except for a case of being specially mentioned. Further, a lid side of thepackage 10a will be defined as "an upper side", and an opposite side (a bottom side of the package will be defined as "a lower side". - The package
main body 20a is a box body having a shape in which an upper end side of a rectangular parallelepiped shape is diagonally cut out. The packagemain body 20a has afront wall 21a and a rear wall of the package main body, which face each other,side walls main body 20a has an upper portion opened, and tobacco products are capable of being put in and taken out. The hinge H is formed at an upper end of the rear wall of the packagemain body 20a. The hinge H extends over between rear portions of upper end edges of therespective side walls lid 30a to be mutually rotatable. - An
inner frame 40a has a substantially U-shaped front surface frame, and side surface frames that are connected to both side edges of the front surface frame. Theinner frame 40a is bonded to an inner surface of the packagemain body 20a, more specifically, inner surfaces of thefront wall 21a and theside walls main body 20a. - The
lid 30a has an oblong rear wall of the lid, which is connected to the hinge H, an oblongtop wall 34a of the lid, which is connected to the rear wall of the lid to be orthogonal to the rear wall, an oblongfront wall 31a of the lid, which is connected to thetop wall 34a of the lid to be orthogonal to thetop wall 34a, and a pair ofside walls side walls lid 30a are respectively trapezoidal, and are connected to respective side edges of the rear wall, thetop wall 34a and thefront wall 31a of the lid. - In the
package 10a according to the second embodiment, theend portion structure 1 of a paper product according to the first embodiment is used in thefront wall 31a of the lid. Theend portion 2 in theend portion structure 1 of a paper product corresponds to thefront wall 31a of the lid, and thebend portion 4 corresponds to a frontwall reinforcement frame 35a of the lid, which reinforces thefront wall 31a of the lid. In a lower edge of thefront wall 31a of the lid, that is, a bend portion of the frontwall reinforcement frame 35a of the lid, the bend line BL and the ruled line RL are present, and the reinforcement frame is bent inward in the bend line BL and the ruled line RL. As a result, as illustrated inFig. 6, Fig. 7 andFig. 8 , thefront wall 31a of the lid slightly curves to expand to the rear side. -
Fig. 9 illustrates a blank in a vicinity of the top wall of the lid, in a blank of the package according to the second embodiment. A front wall panel P1 that is located at an opposite side from a rear wall panel to be thefront wall 31a of the lid is connected to an upper edge of a top wall panel forming thetop wall 34a of the lid. A front wall reinforcement panel P2 that forms the frontwall reinforcement frame 35a of the lid is further connected to an upper edge of the front wall panel P1. The front wall reinforcement panel P2 is bent inward in the bend line BL and the ruled line RL, is laid on the front wall panel P1 and bonded, and thereby reinforces thefront wall 31a of the lid. Side wall panels P3 to be theside walls 32a of the lid respectively connect to both side edges of the front wall panel P1. Panels that are located under the side wall panels P3 are inner top flaps P4 that are laid on the top wall panel and reinforce the top wall of the lid. - In the
package 10a according to the second embodiment, theend portion structure 1 of a paper product according to the first embodiment is used in thefront wall 31a of the lid, and thefront wall 31a of the lid and the frontwall reinforcement panel 35a of the lid slightly curve to expand to the rear side. That is, a tensile force acts on an inside of thefront wall 31a of the lid and the frontwall reinforcement panel 35a of the lid so that thefront wall 31a of the lid expands to the rear side. As a result, deflection of paper due to deterioration over time can be restrained. Thefront wall 31a of the lid and the frontwall reinforcement panel 35a of the lid overlap each other to make a double structure, and further the structure is very simple, so that deterioration hardly occurs. Further, thefront wall 31a of the lid and the frontwall reinforcement panel 35a of the lid slightly curve to expand to the rear side, and are in close contact with theinner frame 40a, and therefore lid closure is enhanced. Further, a gap hardly occurs between thelid 30a and the opening of the packagemain body 20a, and therefore, a tobacco product, for example, a shredded cigarette hardly falls to outside. -

Fig. 15 illustrates a perspective view of a state where an inner box of a package according to a fourth embodiment is housed in an outer box, seen from an upper front side.Fig. 16 illustrates a perspective view of a state where the inner box of the package according to the fourth embodiment is slid from the outer box, seen from the upper front side.Fig. 17 illustrates a perspective view of a state where the inner box of the package according to the fourth embodiment is taken out of the outer box, seen from the upper front side. - A
package 10c according to the fourth embodiment is formed by including anouter box 50 having a substantially rectangular parallelepiped shape having an opening at a right side part, and aninner box 60 that is housed in theouter box 50 and has a substantially rectangular parallelepiped shape in which cigarettes as tobacco products are housed and from which cigarettes are capable of being taken out through an opening at an upper portion. - In the
package 10c according to the fourth embodiment, theend portion structure 1 of a paper product according to the first embodiment is used in atop wall 51 of the outer box. Theend portion 2 of theend portion structure 1 of a paper product corresponds to atop wall 51 of the outer box, and thebend portion 4 corresponds to a topwall reinforcement frame 56 of the outer box that reinforces thetop wall 51 of the outer box. In a right side edge of thetop wall 51 of the outer box, that is, a bend portion of the topwall reinforcement frame 56 of the outer box, the bend line BL and the ruled line RL are present, and the topwall reinforcement frame 56 of the outer box is bent inward in the bend line BL and the ruled line RL. As a result, thetop wall 51 of the outer box slightly curves to expand to a bottom side, as illustrated inFig. 15 and Fig. 16 . - As illustrated in
Fig. 17 , thepackage 10c according to the fourth embodiment includes atop wall 65 of the inner box, which connects to an upper edge of a side wall 62 (a left side) of the inner box, and is connected to a left side upper edge of afront wall 61 of the inner box, and a left side upper edge of arear wall 63 of the inner box. Further, a topwall reinforcement frame 66 of the inner box, which is bent outward and reinforces thetop wall 65 of the inner box, connects to thetop wall 65 of the inner box. In thetop wall 65 of the inner box, theend portion structure 1 of a paper product according to the first embodiment is used. However, in thetop wall 65 of the inner box, theend portion structure 1 of a paper product according to the first embodiment is used in an inverted orientation, that is, in such a manner that thebend portion 4 is bent outward, unlike the embodiments described above. Theend portion 2 of theend portion structure 1 of a paper product corresponds to thetop wall 65 of the inner box, and thebend portion 4 corresponds to the topwall reinforcement frame 66 of the inner box, which is located on an outside of thetop wall 65 of the inner box, and reinforces the top wall of the inner box. The bend line BL and the ruled line RL are present in a right side edge of thetop wall 65 of the inner box, that is, a bend portion of the topwall reinforcement frame 66 of the inner box, and the topwall reinforcement frame 66 of the inner box is bent to outside in the bend line BL and the ruled line RL. As a result, thetop wall 65 of the inner box slightly curves to expand upward, as illustrated inFig. 17 . - In the
package 10c according to the fourth embodiment, theend portion structure 1 of a paper product according to the first embodiment is used in thetop wall 51 of the outer box, and thetop wall 51 of the outer box and the topwall reinforcement frame 56 of the outer box slightly curve to expand to the bottom side. That is, a tensile force acts on an inside of thetop wall 51 of the outer box and the topwall reinforcement frame 56 of the outer box so that thetop wall 51 of the outer box and the topwall reinforcement frame 66 of the outer box expand to the bottom side. As a result, deflection of paper due to deterioration over time can be restrained. Thetop wall 51 of the outer box and the topwall reinforcement frame 66 of the outer box overlap each other to make a double structure, and further the structure is very simple, so that deterioration hardly occurs. Further, thetop wall 51 of the outer box, and the topwall reinforcement frame 56 of the outer box curve to expand to the bottom side, and thereby, a gap hardly occurs between the opening of theouter box 50 and theinner box 60. As a result, a tobacco product, for example, a shredded cigarette can be restrained from dropping to outside. Theend portion structure 1 of a paper product according to the first embodiment may be used in the side wall 62 (the right side) of the inner box. The side wall 62 (the right side) of the inner box is slightly curved so as to expand to a left side, whereby a gap more hardly occurs between the opening of theouter box 50 and theinner box 60. - Further, in the
package 10c according to the fourth embodiment, theend portion structure 1 of a paper product according to the first embodiment is used in thetop wall 65 of the inner box, and thetop wall 65 of the inner box and the topwall reinforcement frame 66 of the inner box slightly curve to expand upward. That is, a tensile force acts on the inside of thetop wall 65 of the inner box and the topwall reinforcement frame 66 of the inner box so that thetop wall 65 of the inner box and the topwall reinforcement frame 66 of the inner box expand upward. As a result, deflection of paper due to deterioration over time can be restrained. Further, thetop wall 65 of the inner box and the topwall reinforcement frame 66 of the inner box overlap each other to make the double structure, and further the structure is very simple, so that deterioration hardly occurs. Further, thetop wall 65 of the inner box and the topwall reinforcement frame 66 of the inner box curve to expand upward, whereby resistance to the inner surface of thetop wall 51 of the outer box becomes large. As a result, theinner box 60 can be prevented from falling off from theouter box 50. - Although preferable embodiments of the present invention are described thus far, the end portion structure of the paper product and the package made of paper according to the present invention can be carried out by combining the respective embodiments as much as possible. Although in the present embodiment, the packages that house tobacco products (for example, cigarettes) are cited as the application examples of the end portion structure of a paper product according to the present invention, the application examples are not limited to these examples. The end portion structure of a paper product according to the present invention can be widely applied to the packages that house articles other than tobacco products.
