Description

The present invention relates to a packaging method and packaging form for packaging an object with a sheet-like packaging material.

A packaging method called a so-called overwrap packaging method has conventionally been carried out by steps as shown in FIG. 8 (see, for example, Patent Document 1).
That is, a sheet-like packaging material 1 cut into a rectangular shape is placed over a square box-shaped object 10 to be packaged, and the packaging material 1 is placed so as to cover the top, front, back, and bottom surfaces of the object 10 to be packaged. The article to be packaged 10 is wrapped around the body (Step A). Next, the ears 20 protruding from both sides of the packaged object 10 are folded in. At this time, first, the front part 20a and the back part 20b of the ear part 20 are folded in toward the side surface of the object to be packaged 10 (step B). When the front part 20a and the back part 20b are folded in, the lower part 20c and the upper part 20d of the ear part 20 are formed into a trapezoidal shape. Next, the lower surface portion 20c of the ear portion 20 is folded in toward the side surface of the object to be packaged 10 (step C), and finally the upper surface portion 20d of the ear portion 20 is folded in toward the side surface of the object to be packaged 10. Paste it on the folded lower surface portion 20c (Step D). Through these series of steps, a packaging form as shown in FIG. 9(a) is completed.

Now, in the packaging form formed by the conventional packaging method, as shown in FIG. appear. Furthermore, portions of the front portion 20a, back portion 20b, and lower surface portion 20c of the ear portion 20 are exposed to the surface on both sides of the packaged object 10. For this reason, the patterns printed on these parts are displayed overlapping each other on both sides of the packaged object 10, resulting in an unsightly appearance. Furthermore, on both sides of the packaged product 10, various symbols and numbers related to the packaged product 10 may be printed and displayed on the upper surface portion 20d of the ear portion 20 placed on the most surface side. If 20d were folded into a trapezoidal shape, there was a risk that part of the printed content would be hidden (see FIG. 9(b)).

The present invention was made in view of the above-mentioned circumstances, and an object of the present invention is to improve packaging quality by focusing on both sides of an object to be packaged.

The packaging method according to the present invention is a method for packaging an object having a hexahedral shape having a front, back, top, bottom, and both side surfaces, with adjacent surfaces intersecting at right angles, and in which a sheet-like product cut into a rectangular shape is used. A wrapping process in which the packaging material is wrapped around the object to be packaged and the packaging material is extended outward from both sides of the object to form a cylindrical ear; For each ear part, any one of its front part, back part, top part, or bottom part is selected as the first folding flap, and the first folding flap is folded toward both sides of the packaged object. In the folding process, at each edge of the packaging material, the portions adjacent to both sides of the first folding flap are used as side folding flaps, and the portions facing the first folding flap are used as surface flaps, and these side folding flaps and A second folding step of folding the surface flap toward both sides of the packaged object is included.
Then, in the first folding step, both edges of the first folding flap are folded in line with both edges of each side of the packaged object, and in the second folding step, each side folding flap is arranged inside the surface flap. In addition, both edges of the surface flap are arranged in alignment with both edges of each side surface of the packaged object.

In this manner, by folding the first folding flap, each side folding flap, and the surface flap, the surface flaps appear on the surface over the entire width on both sides of the packaged object. Thereby, it is possible to realize packaging that gives a clean impression on both sides of the packaged item.

Furthermore, in the body wrapping process, each ear part is formed so that the length extending from both side surfaces of the packaged object matches the length of both end edges of each side surface of the packaged object. Surface flaps appear on the surface over the entire surface. This gives a cleaner impression on both sides of the packaged item, and since the surface flap is rectangular when printing, it is possible to form a large printing area that is easy to print. Since the folding flap is folded back outward, the sealing performance is also improved compared to the conventional technology.

Furthermore, in the body wrapping process, if both edges of the packaging material are overlapped on the lower surface of the packaged object, and in the first folding process, the lower surface part of each ear is selected as the first folding flap, the overlapping part of the packaging material can be overlapped. is placed under the object to be packaged, and since the overlapping portions are hidden by surface flaps on both sides of the object, it is possible to realize packaging with an even neater impression.

Next, the packaging form according to the present invention is a packaging form for a packaged object having a hexahedral shape having a front surface, a back surface, a top surface, a bottom surface, and both side surfaces, and adjacent surfaces intersecting at right angles, and is cut into a rectangular shape. A sheet-like packaging material is wrapped around the packaged object, and the packaging material is extended outward from both sides of the packaged object to form a cylindrical ear, which extends from both sides of the packaged object. For each ear to be packaged, select one of its front part, back part, top part, or bottom part as the first folding flap, and use both edges of the first folding flap as both edges of each side of the packaged object. , the first folding flaps are folded toward both sides of the packaged item, and further, in each ear of the packaging material, the portions adjacent to both sides of the first folding flaps are used as side folding flaps, and 1. The part facing the first folding flap is used as the front flap, and each side folding flap is arranged inside the front flap, and both edges of the front flap are aligned with both edges of each side of the packaged item. It is characterized in that the side folding flaps and the front flaps are formed by folding them toward both sides of the packaged item.

In this manner, by folding the first folding flap, each side folding flap, and the surface flap, the surface flaps appear on the surface over the entire width on both sides of the packaged object. As a result, it is possible to realize a packaging form that gives a clean impression on both sides of the packaged item.

Furthermore, by forming the length of each ear portion to match the length of both edges of each side surface of the packaged object, the length of each ear portion extending from both sides of the packaged object can be formed to match the length of both edges of each side surface of the packaged object, so that the surface area extends over the entire both sides of the packaged object. A flap appears on the surface. This gives a cleaner impression on both sides of the packaged item, and since the surface flap is rectangular when printing, it is possible to form a large printing area that is easy to print. Since the folding flap is folded back outward, the sealing performance is also improved compared to the conventional technology.

Furthermore, by overlapping both edges of the packaging material on the underside of the object to be packaged, and by selecting the lower surface portion of each ear as the first folding flap, the overlapping portion of the packaging material is placed under the object to be packaged, Moreover, since the overlapped portions on both sides of the packaged object are hidden by surface flaps, it is possible to realize a packaging form with an even neater impression.

As explained above, according to the present invention, it is possible to improve the packaging quality, especially on both sides of the packaged object.

Embodiments of the present invention will be described in detail below with reference to the drawings.
FIG. 1 is a process diagram of the packaging method according to this embodiment.
The packaging method according to the present embodiment includes a plurality of steps, in which an object to be packaged 10 is overwrapped using a sheet-like packaging material 1 (for example, wrapping paper or packaging film) cut into a rectangular shape.
As shown in FIG. 2, the packaged object 10 has a front surface 11, a back surface 12, an upper surface 13, a lower surface 14, and both side surfaces 15, 15, and has a hexahedral shape (i.e., a rectangular parallelepiped or a cube) in which adjacent surfaces intersect at right angles. It is aimed at those of. Examples of this type of packaged object 10 include a packaging box containing a product such as a confectionery, a bundle of sheet-like products such as copy paper, and the like.

As shown in FIG. 1, the packaging method according to the present embodiment includes a body wrapping process, a first folding process, and a second folding process, and the packaging method includes a wrapping process, a first folding process, and a second folding process. 10 is transported, each of these steps is carried out during the transport process, and the packaging form described below is finished.

First, in the body wrapping process, a sheet-like packaging material 1 cut into a rectangular shape is placed on the top surface 13 of the packaged product 10 supplied to the packaging line, and the top surface 13, front surface 11, and rear surface of the packaged product 10 are The article to be packaged 10 is wrapped around the body with the packaging material 1 so as to wrap the article 12 and the lower surface 14. Both edges of the packaging material 1 are overlapped at the lower surface 14 of the object to be packaged 10. In this way, by arranging the overlapping portion 1a of the packaging material 1 on the lower surface 14 of the object to be packaged 10, the overlapping portion 1a is hidden by the object to be packaged 10 when the object to be packaged 10 is normally arranged. This gives it a clean appearance. The overlapped portions 1a of the packaging material 1 are pasted together using an adhesive such as glue or adhesive tape.
Through this body wrapping process, a body wrapping packaging form as shown in FIG. 3 is formed.

In the body-wrap packaging form shown in FIG. A cylindrical ear portion 20 is formed by extending the packaging material 1. Each of these ear portions 20 is folded into both side surfaces 15, 15 of the object to be packaged 10 through a first folding step and a second folding step, which will be described later.

In this embodiment, as shown in FIG. , 15a are formed to match the length L0 of each ear. That is, it is set as L1=L0.

Next, a first folding step is performed on the ears 20 of the packaging material 1 with the object to be packaged 10 wrapped around it.
In this embodiment, the lower surface portion of each ear portion 20 is set as the first folding flap 21, and the first folding flap 21 is folded toward both sides 15, 15 of the packaged object 10, respectively. At this time, both edges of the first folding flap 21 are aligned with both edges 15a, 15a of each side surface 15, 15 of the object to be packaged 10.

Here, as shown in FIG. 3, in each ear portion 20 of the packaging material 1 in which the article to be packaged 10 is wrapped around the body, both side portions adjacent to both sides of the first folding flap 21 are referred to as side folding flaps 22, 22, A portion facing the first folding flap 21 (in this embodiment, the upper surface portion) is a front flap 23.

In addition, at the stage where the body wrapping process is completed, the boundaries between the first folding flap 21, the side folding flaps 22, 22, and the surface flap 23 do not normally appear clearly as shown in FIG. However, as the process progresses, the boundaries between them are folded in, and the first fold-in flap 21, the side fold-in flaps 22, 22, and the surface flap 23 can be clearly distinguished.

In the process of folding the first folding flap 21 toward both sides 15, 15 of the article to be packaged 10, the boundaries between the first folding flap 21 and the side folding flaps 22, 22 are valley-folded, and the sides are folded. The partial folding flaps 22, 22 are mountain-folded along the diagonal line X. The side folding flaps 22, 22 folded in this way are formed into a right triangular shape by overlapping both sides of the mountain-folded diagonal line X (see FIG. 4).

Further, by the first folding step, the first folding flaps 21 of each ear portion 20 are overlapped with both side surfaces 15, 15 of the packaged object 10, respectively. In this embodiment, as described above, the length L1 of each ear portion 20 is set to match the length L0 of both end edges 15a, 15a of each side surface 15, 15 of the object to be packaged 10. The area of each side surface 15, 15 of the object 10 and the first folding flap 21 form a rectangle with the same area, and as a result, the first folding flap 21 is superimposed on the entire surface of each side surface 15, 15 of the object 10 to be packaged.

FIG. 4 shows an intermediate packaging state after the first folding process has been completed.
As mentioned above, the side folding flaps 22, 22 are formed into a right triangle shape at the time when the first folding step is completed.

Next, a second folding step is performed on the ears 20 of the packaging material 1.
FIG. 5 shows the packaging state during the second folding process.
In the second folding step, the surface flap 23 of each ear portion 20 and each side folding flap 22, 22 adjacent to both sides of this surface flap 23 are turned toward both sides 15, 15 of the packaged object 10, respectively. Fold it in. At this time, as shown in FIG. 5, the boundaries between the front flap 23 and each side folding flap 22, 22 are mountain-folded, and the middle part of each side folding flap 22, 22 is valley-folded. Each side folding flap 22, 22 is folded inside the flap 23. Specifically, as shown in FIG. 4, each of the side folding flaps 22, 22 is inserted along a perpendicular line a drawn from the apex c to the base b of the side folding flaps 22, 22 shaped like a right triangle. Fold it in the valley and fold it in.

Then, both end edges 23a, 23a of the surface flap 23 are arranged in alignment with both end edges 15a, 15a of each side surface 15, 15 of the object to be packaged 10. In this embodiment, as described above, the length L1 of each ear portion 20 is set to match the length L0 of both end edges 15a, 15a of each side surface 15, 15 of the object to be packaged 10. The area of each side surface 15, 15 of the object 10 and the surface flap 23 form a rectangle with the same area. 23 are superimposed.

As a result, as shown in FIG. 6(a), the surface flaps 23 are arranged on the entire surface of both sides 15, 15 of the packaged object 10, and the first folding flap 21 and the side folding flaps 22, 22 is folded inside this surface flap 23 and is hidden. Furthermore, the overlapped portion 1a of the packaging material 1 is also placed inside the surface flap 23 and is hidden. As a result, it is possible to realize a packaging form in which both sides 15, 15 of the packaged object 10 have a neat impression.

As shown in FIG. 6(b), printing or printing areas 23b can also be formed on the surface flaps 23 disposed on the surfaces of both side surfaces 15, 15 of the object to be packaged 10. For example, a product symbol representing the contents of the packaged object 10, an expiration date, etc. can be printed on the printing or printing area 23b formed on the surface flap 23. Further, a pattern may be applied to the surface flap 23.

Note that the present invention is not limited to the embodiments described above, and it goes without saying that various modifications and applications can be made as necessary.
For example, as shown in FIG. 7(a), if the surface flap 23 is disposed on the entire width L2 of both side surfaces 15, 15 of the object to be packaged 10, It does not have to be in a form that covers the entire area. In this way, even if the surface flaps 23 are arranged over the entire width L2 of both side surfaces 15, 15 of the object to be packaged 10, a packaging form that gives a neat impression on both side surfaces 15, 15 of the object to be packaged 10 can be realized. can do. Moreover, a sufficient printing or printing area can be secured on the surface flap 23.
In such a packaging form, as shown in FIG. 7(b), the length L1 of the ear portion 20 is set shorter than the length L0 of both end edges 15a, 15a of each side surface 15, 15 of the packaged object 10. This can be achieved by doing so.
In this packaging form, after the first folding flap 21 is folded toward both sides 15, 15 of the packaged object 10, the side folding flaps 22, 22 are folded in from the apex c (corner of the packaged object 10). It can be formed by valley-folding and folding along the perpendicular line a drawn to the bottom b (the ridge line when the middle part is mountain-folded).

Further, in the embodiment described above, the lower surface portion of the ear portion 20 is set as the first folding flap 21, but the present invention is not limited to this, and either the upper surface portion or the side portion of the ear portion 20 is set as the first folding flap 21. May be set.
