  However, in these packages, the packaging film is easily opened, but there is a problem that the packaging film may be unintentionally opened during transportation and transportation. Moreover, it is necessary to attach a separate member such as an opening tape or a separating tape when manufacturing the package, and there are still problems to be solved from the viewpoint of easily manufacturing the package and improving productivity. It was a thing.

  The present invention has been made to solve such problems of the prior art, and can effectively prevent a situation in which a packaging film is unintentionally opened during transportation and transportation. The present invention provides a package that is easy to manufacture and can be manufactured with high productivity.

  As a result of intensive studies to solve the problems of the prior art as described above, the inventor arranges an opening band as an opening means in an oblique direction with respect to the stacking direction of the objects to be packaged. The present invention has been completed by conceiving that the above-mentioned problems can be solved by giving a part of the film (side edge portion) a function as an opening tape or the like. Specifically, the following packages are provided by the present invention.

[1] A laminated body in which a plurality of packaging bodies are laminated in multiple stages and a packaging film that encapsulates the laminated body, and the packaging film has one side edge and the other side edge overlapping each other. As described above, it is wound around the circumferential surface of the laminated body and joined along the laminating direction of the laminated body so that a tip end portion of at least one side edge portion becomes a free end portion. And a pair of opening cut lines are formed in the packaging film, and an area between the pair of opening cut lines is an open band, and the opening band is a portion of the free end. A packaging body that is formed in an oblique direction with respect to the stacking direction of the packaging bodies as a starting point.

  The packaging body of the present invention can effectively prevent a situation in which the packaging film is unintentionally opened during transportation and transportation. Moreover, it is easy to manufacture and can be manufactured with high productivity.

  Hereinafter, the best mode for carrying out the package of the present invention will be specifically described with reference to the drawings. However, the present invention broadly encompasses a package including the device-specific matters, and is not limited to the following embodiments.

[1] Structure of features of the present invention:
The package body of the present invention is, for example, like the package body 1A shown in FIGS. 1 and 2, the package body 2 is formed so that the one side edge portion and the other side edge portion overlap each other. It is wound around the circumferential surface of the laminated body 10 laminated in a plurality of stages, and is joined along the lamination direction of the laminated body 10 so that the distal end side of at least one side edge portion 12 becomes the free end portion 14. 16 is formed, the packaging film 4 is formed with a pair of opening cut lines 18a and 18b, and an area between the pair of opening cutting lines 18a and 18b is an opening band 20. The unsealing band 20 is a package body that is formed in an oblique direction with respect to the stacking direction of the package body 2, starting from the tip of the free end portion 14. A package 1A shown in FIGS. 1 and 2 is an example of a package in which the package 2 is a tissue carton, and the five packages 2a, 2b, 2c, 2d, and 2e are vertically arranged in five stages. The packaging film 4 is wrapped around the circumferential surface of the laminated body 10 that has been laminated.

  In the conventional package, opening means such as perforations are arranged along the stacking direction of the packaged body or perpendicular to the stacking direction, and the opening means is arranged along the boundaries of the plurality of packaged objects. Often placed. However, such a package has a horizontal displacement force or a horizontal displacement with respect to the packaging film when a plurality of packages within the package are displaced along the boundary during transportation and transportation. The spreading force acts, and there is a problem that the perforations formed in the stacking direction (vertical direction) of the packaged body and the direction (horizontal direction) orthogonal to the stacking direction of the packaged body are broken.

  Therefore, in the packaging body of the present invention, the opening band 20 formed between the pair of opening cut lines 18 a and 18 b is arranged obliquely with respect to the stacking direction of the stacked body 10. In this way, the opening band 20 (and thus the opening cutting lines 18a and 18b) that is the opening means is inclined with respect to the direction of the force acting during transportation and transportation, and arranged at a certain angle. Therefore, it is possible to effectively prevent a situation in which the opening cut lines 18a and 18b are not easily subjected to a large breaking force, and the packaging film is unintentionally opened during transportation and transportation.

  In addition, since the conventional packaging body is provided with other members such as an opening tape and a separating tape for the purpose of facilitating the opening of the packaging film, the manufacturing process of the packaging body is increased. Was reducing productivity.

  Therefore, in the packaging body of the present invention, a conventional packaging film is wound around the peripheral surface of the laminate so that one side edge and the other side edge overlap, and the side edges are joined together. Using the packaging form (caramel packaging etc.) to join, the free end part 14 is formed in a part of the packaging film 4 at the time of joining, and the opening band 20 is formed starting from the tip of the free end part 14. It was decided. According to such a configuration, since the free end portion 14 functions as an opening tape or the like, there is no need to attach separate members such as an opening tape and a separating tape when manufacturing the packaging body, and the packaging body is simplified. It becomes possible to improve productivity.

  In the packaging body of the present invention, the packaging film is wound around the circumferential surface of the laminate so that the one side edge portion and the other side edge portion overlap each other, and the leading end side of at least one side edge portion becomes the free end portion. Next, it joins along the lamination direction of a to-be-packaged body, and forms a junction part.

  The winding direction of the packaging film is a direction orthogonal to the stacking direction of the laminate, that is, the horizontal direction. Thereby, at least the peripheral surface of the package is encapsulated. A packaging body 1A shown in FIGS. 1 and 2 is a rectangular parallelepiped packaging body, and a packaging film 4 is wound around its peripheral surface, that is, four side surfaces. However, the upper surface and the bottom surface of the laminate may be encapsulated with a packaging film.

  The side edges of the packaging film preferably overlap 50 to 100 mm at the tip, and more preferably 60 to 90 mm. When the overlap part of a packaging film is less than 50 mm, when forming a junction part, a high processing precision will be requested | required and manufacture of a package may become difficult. If the overlapping portion of the packaging film exceeds 100 mm, the free end becomes wider than necessary, and the manufacturing cost increases.

  In the packaging body of the present invention, the joining portion is formed along the stacking direction of the packaging body, that is, in the vertical direction. The method for forming the joint is not particularly limited, but a method such as heat sealing or ultrasonic fusion is preferably used. As shown in FIG.1 and FIG.2, 5-15 mm is preferable and, as for the width W1 of the junction part 16, 5-10 mm is still more preferable. If the width of the joint is less than 5 mm, sufficient bonding strength cannot be obtained. In other words, there is a possibility that the opening cut line is difficult to break.

  As shown in FIGS. 1 and 2, a free end portion 14 is formed on the distal end side of one side edge portion 12 of the packaging film 4. The width W2 of the free end portion 14 is preferably 10 to 30 mm, and more preferably 15 to 25 mm. If the width of the free end portion is less than 10 mm, it is difficult to pick the free end portion, and it may be difficult to break the opening cut line. When the width of the free end exceeds 30 mm, the width of the free end becomes unnecessarily large, and it becomes a hindrance during transportation, such as being caught by another object during transportation.

  In addition, as shown in FIG.1 and FIG.2, it is more preferable that the front-end | tip of the free end part 14 of the packaging film 4 is cut in zigzag shape, such as a wave shape and a saw blade shape. Since the tip of the free end is cut in a zigzag shape, the opening cut line can be easily broken starting from the zigzag cut portion.

  In the package of the present invention, a pair of opening cut lines, that is, a pair of opening cut lines, is formed on the packaging film. The opening cut line may be a so-called perforation, or may be formed by intermittently forming relatively long cuts. However, perforations are preferred from the viewpoint of preventing unexpected breakage.

  In the package of this invention, as shown in FIG.1 and FIG.2, the area | region between a pair of opening cut lines 18a and 18b is the opening band 20 which is an opening means. When the pair of opening cut lines are broken, an opening band that is a band-shaped member is formed, and the opening of the package is achieved by pulling the opening band.

  The unsealing band 20 is formed in an oblique direction with respect to the stacking direction of the packaged body 2, starting from the tip of the free end 14 formed on the tip side of one side edge 12 of the packaging film 4. . The degree of inclination with respect to the stacking direction of the packaged body is not particularly limited. However, it is preferable to incline 20-70 degrees with respect to the lamination direction (namely, vertical direction) of a to-be-packaged body, and it is still more preferable to incline 30-60 degrees. If it is less than 20 °, the inclination is too small, and there is a risk of causing the same problem as that in which the opening means is simply arranged in the vertical direction. On the other hand, when the angle exceeds 70 °, the inclination is excessively large, and the same problem as that in which the opening means is arranged in the horizontal direction may occur.

  The opening band is preferably formed from the portion of the packaging film that encloses the uppermost package body to the portion that encapsulates the lowermost package body. For example, in the package 1 </ b> A shown in FIG. 1, five packages 2 (tissue cartons) are laminated to form a laminate 10, and the unsealing band 20 is the uppermost layer of the package film 4. It is formed from the portion enclosing the package 2a to the portion enclosing the lowermost package 2e.

  In this case, the opening band may be formed from the portion of the packaging film that encloses the uppermost package body to the portion that encapsulates the lowermost package body, and its directionality is It is not limited. That is, in the example shown in FIG.1 and FIG.2, the starting point is formed in the upper part of the package 1A, and the opening band 20 is arrange | positioned toward the lower part from there, On the contrary, it is in the lower part of a package. A starting point is formed, and an opening band may be arranged from there to the upper part. However, as shown in FIG. 1, it is preferable that the starting point is formed at the upper part of the package 1A and the opening band 20 is arranged from there to the lower part in that the starting point is at the upper part and the opening is easy. .

  Moreover, as shown in FIG.1 and FIG.2, it is preferable that the opening band 20 is formed so that a width | variety may become narrow as it goes to an end point from the starting point. Such a configuration has an advantage that when the starting part of the opening band is pulled, the tensile force reaches the end part without being attenuated, and the opening band can be easily broken. As a degree of narrowing the width, the ratio of the width of the end point portion to the width of the start point portion is preferably 40 to 90%, and more preferably 50 to 80%. If it is less than 40%, the width on the end point side of the opening band becomes too narrow, and the opening band may be broken in the middle. On the other hand, if it exceeds 90%, the tensile force may not sufficiently converge on the end point side, and it may not be possible to break to the end point of the opening band.

  Furthermore, it is preferable that the opening band is formed so as to surround 50% of the circumference of the laminated body in the packaging film. By carrying out like this, a packaging film is fully fractured | ruptured and it becomes easy to take out the to-be-packaged body which is the contents. In order to exhibit such an effect more reliably, it is more preferable that the packaging film is formed so as to surround 70% of the peripheral diameter of the laminate. For example, in the case of a package body in which a rectangular parallelepiped package body such as a tissue carton is packaged, it is preferable that an opening band is formed so as to surround three sides of a rectangular outer peripheral shape.

  Furthermore, it is preferable that the packaging body of the present invention is provided with a marking that indicates the position of the starting point of the opening band. By this marking, the user can find out the starting point of the unsealing band without making a mistake, and can surely break the unsealing cut line and open the packaging film.

  The mode of marking is not particularly limited, and characters, symbols, figures, coloring, and the like can be employed. The marking may be applied to a free end formed on the leading end side of one side edge of the packaging film, or may be applied to a portion near the free end of the packaging film. In the package 1 </ b> A shown in FIG. 1, two types of markings 22 are attached to a portion in the vicinity of the free end portion 14 of the packaging film 4. One is a marking 22a made up of the characters "can be peeled from here", and the other is a marking 22b made up of a colored arrow symbol.

  In the package of this invention, it is preferable that the peeling strength of a junction part is lower than the breaking strength of the cutting line for opening. By setting the peel strength of the joint within this range, it is possible to obtain an effect that the tear strip can be reliably broken while peeling the joint. The breaking strength of the opening cut line can be appropriately adjusted by adjusting the pitch of the perforations when the opening cut line is formed by perforations.
