Description

この発明は、被包装物をシート状の包装材で包装するための包装方法と包装形態に関する。 The present invention relates to a packaging method and packaging form for packaging an object with a sheet-like packaging material.

いわゆる上包み包装方法と称する包装方法は、従来、図８に示すような工程により実行されていた（例えば、特許文献１を参照）。
すなわち、角箱形状の被包装物１０に対して、矩形状に裁断したシート状の包装材１を上面から被せ、当該被包装物１０の上面、正面、背面及び下面を包むように、包装材１で被包装物１０を胴巻きする（工程Ａ）。次いで、被包装物１０の両側面から突き出した各耳部２０を折り込んでいく。このときは、まず耳部２０の正面部分２０ａと背面部分２０ｂを被包装物１０の側面に向かって折り込んでいく（工程Ｂ）。正面部分２０ａと背面部分２０ｂが折り込まれると、耳部２０の下面部分２０ｃと上面部分２０ｄは台形状に成形される。次に、耳部２０の下面部分２０ｃを被包装物１０の側面に向かって折り込み（工程Ｃ）、最後に耳部２０の上面部分２０ｄを被包装物１０の側面に向かって折り込んで、先に折り込まれた下面部分２０ｃに貼り付ける（工程Ｄ）。これら一連の工程を経て、図９（ａ）に示すような包装形態が完成する。 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.

さて、従来の包装方法により形成した包装形態は、図９（ｂ）に示すように、台形状に成形された耳部２０の上面部分２０ｄの全体が、被包装物１０の両側面において表面に現れる。さらに、耳部２０の正面部分２０ａ、背面部分２０ｂ及び下面部分２０ｃも、一部が被包装物１０の両側面において表面に露出する。このため、これら各部分に印刷された模様等が、被包装物１０の両側面で重なり合って表示され、見栄えが良くないという課題を有していた。また、被包装物１０の両側面において、いちばん表面に置かれる耳部２０の上面部分２０ｄに、被包装物１０に関する各種の記号や数字等を印字して表示することもあるが、その上面部分２０ｄが台形状に折り込まれていると、それらの印字内容の一部が隠れてしまうおそれがあった（図９（ｂ）参照）。 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)).

特開昭５５－１２０１３号公報Japanese Unexamined Patent Publication No. 55-12013

本発明は、上述した事情に鑑みてなされたもので、被包装物の両側面に着目して包装品質の向上を図ることを目的とする。 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.

本発明に係る包装方法は、正面、背面、上面、下面及び両側面を有し隣接する面が直角に交わる六面体形状をした被包装物の包装方法であって、矩形状に裁断したシート状の包装材を被包装物に胴巻きするとともに、被包装物の両側面よりも外側に当該包装材を延出させて筒形の耳部を形成する胴巻き工程と、包装材の両側面から延出する各耳部について、その正面部分、背面部分、上面部分又は下面部分のいずれか一つを第１折込みフラップとして選択し、当該第１折込みフラップを被包装物の両側面に向けてそれぞれ折り込む第１折込み工程と、包装材の各耳部において、第１折込みフラップの両側に隣接する部分を側部折込みフラップとし、第１折込みフラップに対向していた部分を表面フラップとして、これら側部折込みフラップ及び表面フラップを被包装物の両側面に向けて折り込む第２折込み工程と、を含んでいる。
そして、第１折込み工程では、第１折込みフラップの両端縁を、被包装物の各側面の両端縁に合わせて折り込み、第２折込み工程では、各側部折込みフラップを表面フラップの内側に配置するとともに、表面フラップの両端縁を被包装物の各側面の両端縁に合わせて配置することを特徴とする。 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.

このように、第１折込みフラップ、各側部折込みフラップ及び表面フラップを折り込むことで、被包装物の両側面において、表面フラップが全幅にわたって表面に現れる。これにより、被包装物の両側面がすっきりとした印象の包装を実現することができる。 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.

さらに、胴巻き工程において、各耳部は、被包装物の両側面から延出する長さを、被包装物の各側面の両端縁の長さに合わせて形成することで、被包装物の両側面全体にわたって表面フラップが表面に現れる。これにより、被包装物の両側面がいっそうすっきりとした印象となり、印刷する際に表面フラップが矩形なので、印刷し易い大きな印字領域を形成でき、また表面フラップが矩形で接着領域が広く、側部折込フラップが外側に向かって折り返されているので、従来技術に比べ、密封性も向上した。 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.

さらに、胴巻き工程において、被包装物の下面で包装材の両端縁を重ね合わせ、且つ第１折込み工程において、各耳部の下面部分を第１折込みフラップとして選択すれば、包装材の重ね合わせ部分が被包装物の下に配置され、しかも被包装物の両側面では当該重ね合わせ部分が表面フラップで隠されるため、いっそうすっきりとした印象の包装を実現することができる。 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.

次に、本発明に係る包装形態は、正面、背面、上面、下面及び両側面を有し隣接する面が直角に交わる六面体形状をした被包装物の包装形態であって、矩形状に裁断したシート状の包装材を被包装物に胴巻きするとともに、被包装物の両側面よりも外側に当該包装材を延出させて筒形の耳部を形成し、被包装物の両側面から延出する各耳部について、その正面部分、背面部分、上面部分又は下面部分のいずれか一つを第１折込みフラップとして選択し、当該第１折込みフラップの両端縁を被包装物の各側面の両端縁に合わせて、当該第１折込みフラップを被包装物の両側面に向けてそれぞれ折り込み、さらに、包装材の各耳部において、第１折込みフラップの両側に隣接する部分を側部折込みフラップとし、第１折込みフラップに対向していた部分を表面フラップとして、各側部折込みフラップを表面フラップの内側に配置するとともに、表面フラップの両端縁を被包装物の各側面の両端縁に合わせて配置するように、側部折込みフラップ及び表面フラップを被包装物の両側面に向けて折り込んで形成することを特徴とする。 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.

このように、第１折込みフラップ、各側部折込みフラップ及び表面フラップを折り込むことで、被包装物の両側面において、表面フラップが全幅にわたって表面に現れる。これにより、被包装物の両側面がすっきりとした印象の包装形態を実現することができる。 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.

さらに、各耳部は、被包装物の両側面から延出する長さを、被包装物の各側面の両端縁の長さに合わせて形成することで、被包装物の両側面全体にわたって表面フラップが表面に現れる。これにより、被包装物の両側面がいっそうすっきりとした印象となり、印刷する際に表面フラップが矩形なので、印刷し易い大きな印字領域を形成でき、また表面フラップが矩形で接着領域が広く、側部折込フラップが外側に向かって折り返されているので、従来技術に比べ、密封性も向上した。 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.

さらに、被包装物の下面で包装材の両端縁を重ね合わせ、且つ各耳部の下面部分を第１折込みフラップとして選択すれば、包装材の重ね合わせ部分が被包装物の下に配置され、しかも被包装物の両側面では当該重ね合わせ部分が表面フラップで隠されるため、いっそうすっきりとした印象の包装形態を実現することができる。 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.

以上説明したように、本発明によれば、特に被包装物の両側面における包装品質の向上を図ることができる。 As explained above, according to the present invention, it is possible to improve the packaging quality, especially on both sides of the packaged object.

以下、この発明の実施の形態について図面を参照して詳細に説明する。
図１は、本実施形態に係る包装方法の工程図である。
本実施形態に係る包装方法は、複数の工程で構成され、矩形状に裁断したシート状の包装材１（例えば、包装紙や包装フィルム）によって被包装物１０を上包み包装する。
被包装物１０は、図２に示すように、正面１１、背面１２、上面１３、下面１４及び両側面１５，１５を有し、隣接する面が直角に交わる六面体形状（すなわち、直方体又は立方体）のものを対象としている。この種の被包装物１０としては、例えば、包装箱に菓子等の製品を収容したものや、コピー用紙をはじめとするシート状製品の束などがある。 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.

図１に示すように、本実施形態に係る包装方法は、胴巻き工程、第１折込み工程、第２折込み工程の各工程を含み、図示しない包装機械で構築された包装ラインに沿って被包装物１０を搬送し、その搬送過程でこれらの各工程が実施され、後述する包装形態に仕上げられる。 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.

まず、胴巻き工程では、包装ラインに供給された被包装物１０に対して、矩形状に裁断したシート状の包装材１を上面１３から被せ、当該被包装物１０の上面１３、正面１１、背面１２及び下面１４を包むように、包装材１で被包装物１０を胴巻きする。包装材１の両端縁は、被包装物１０の下面１４で重ね合わせる。このように、包装材１の重ね合わせ部分１ａを被包装物１０の下面１４に配置することで、被包装物１０の通常の配置状態では、当該重ね合わせ部分１ａが被包装物１０に隠されて、すっきりとした印象の外観となる。包装材１の重ね合わせ部分１ａは、糊等の接着剤や粘着テープを用いて貼り合わせる。
この胴巻き工程により、図３に示すような胴巻き包装形態が形成される。 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.

図３に示す胴巻き包装形態において、包装材１の幅寸法は、被包装物１０の幅寸法よりも長く設定してあり、両端部分には、被包装物１０の両側面１５，１５よりも外側に包装材１を延出させて筒形の耳部２０が形成される。これら各耳部２０は、後述する第１折込み工程及び第２折込み工程を経て、被包装物１０の両側面１５，１５にそれぞれ折り込まれる。 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.

本実施形態では、図３に示すように、被包装物１０の両側面１５，１５から延出する各耳部２０の長さＬ１を、被包装物１０の各側面１５，１５の両端縁１５ａ、１５ａの長さＬ０に合わせて、各耳部２０を形成してある。すなわち、Ｌ１＝Ｌ０に設定してある。 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.

次に、被包装物１０を胴巻きした包装材１の耳部２０に対して、第１折込み工程を実施する。
本実施形態では、各耳部２０の下面部分を第１折込みフラップ２１として設定し、この第１折込みフラップ２１を被包装物１０の両側面１５，１５に向けてそれぞれ折り込んでいく。このとき、第１折込みフラップ２１の両端縁を、被包装物１０の各側面１５，１５の両端縁１５ａ、１５ａに合わせるようにする。 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.

ここで、図３に示すように被包装物１０を胴巻き包装した包装材１の各耳部２０において、第１折込みフラップ２１の両側に隣接する両側面部分を側部折込みフラップ２２，２２とし、第１折込みフラップ２１と対向する部分（本実施形態では上面部分）を表面フラップ２３とする。 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.

なお、胴巻き工程が終了した段階では、通常、これら第１折込みフラップ２１、側部折込みフラップ２２，２２及び表面フラップ２３の境界が、図３に示すように明瞭には現れない。しかし、工程が進むうちに、それらの境界部分が折り込まれて、第１折込みフラップ２１、側部折込みフラップ２２，２２及び表面フラップ２３が明瞭に区分できるようになる。 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.

第１折込みフラップ２１を被包装物１０の両側面１５，１５に向けてそれぞれ折り込んでいく過程で、第１折込みフラップ２１と側部折込みフラップ２２，２２との境界が谷折りされるとともに、側部折込みフラップ２２，２２は対角線Ｘに沿って山折りされる。このように折り込まれた側部折込みフラップ２２，２２は、山折りされた対角線Ｘの両側が重ね合わされて、直角三角形状に成形される（図４参照）。 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).

また、第１折込み工程により、各耳部２０の第１折込みフラップ２１は、それぞれ被包装物１０の両側面１５，１５に重ね合わされる。本実施形態では、上述したように各耳部２０の長さＬ１を、被包装物１０の各側面１５，１５の両端縁１５ａ、１５ａの長さＬ０に合わせて設定してあるので、被包装物１０の各側面１５，１５の面積と第１折込みフラップ２１とが同じ面積の四角形となり、その結果、被包装物１０の各側面１５，１５の全面に第１折込みフラップ２１が重ね合わされる。 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.

図４は、第１折込み工程を終えた中間の包装状態を示している。
既述したように、第１折込み工程を終えた時点で、側部折込みフラップ２２，２２は直角三角形状に成形されている。 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.

次に、包装材１の耳部２０に対して、第２折込み工程を実施する。
図５は、第２折込み工程の実施途中における包装状態を示している。
第２折込み工程では、各耳部２０の表面フラップ２３と、この表面フラップ２３の両側に隣接する各側部折込みフラップ２２，２２とを、被包装物１０の両側面１５，１５に向けてそれぞれ折り込んでいく。このとき、図５に示すように、表面フラップ２３と各側部折込みフラップ２２，２２との境界をそれぞれ山折りするとともに、各側部折込みフラップ２２，２２の中間部を谷折りして、表面フラップ２３の内側に各側部折込みフラップ２２，２２を折込んでいく。具体的には、図４に示すように、直角三角形状に成形された側部折込みフラップ２２，２２の頂点ｃから底辺ｂに引いた垂線ａに沿って、各側部折込みフラップ２２，２２を谷折りして折り込んでいく。 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.

そして、表面フラップ２３の両端縁２３ａ，２３ａを、被包装物１０の各側面１５，１５の両端縁１５ａ、１５ａに合わせて配置する。本実施形態では、上述したように各耳部２０の長さＬ１を、被包装物１０の各側面１５，１５の両端縁１５ａ、１５ａの長さＬ０に合わせて設定してあるので、被包装物１０の各側面１５，１５の面積と表面フラップ２３とが同じ面積の四角形となり、その結果、被包装物１０の各側面１５，１５の全面に、第１折込みフラップ２１を挟んで、表面フラップ２３が重ね合わされる。 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.

これにより、図６（ａ）に示すように、被包装物１０の両側面１５，１５において、その表面の全体に表面フラップ２３が配置され、第１折込みフラップ２１や側部折込みフラップ２２，２２は、この表面フラップ２３の内側に折り込まれて隠される。さらに、包装材１の重ね合わせ部分１ａも表面フラップ２３の内側に配置されて隠される。その結果、被包装物１０の両側面１５，１５がすっきりとした印象の包装形態を実現することができる。 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.

図６（ｂ）に示すように、被包装物１０の両側面１５，１５における表面に配置された表面フラップ２３には、印刷又は印字領域２３ｂを形成することもできる。例えば、表面フラップ２３に形成した印刷又は印字領域２３ｂに、被包装物１０の内容を表す商品記号や、賞味期限などを印字することができる。また、表面フラップ２３に模様を施してもよい。 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.

なお、本発明は上述した実施形態に限定されるものではなく、必要に応じて種々の変形実施や応用実施が可能であることは勿論である。
例えば、図７（ａ）に示すように、表面フラップ２３は、被包装物１０の両側面１５，１５の全幅Ｌ２にわたってその表面に配置されていれば、被包装物１０の両側面１５，１５の全体を覆う形態でなくてもよい。このように、被包装物１０の両側面１５，１５の全幅Ｌ２にわたって表面フラップ２３が配置されているだけでも、当該被包装物１０の両側面１５，１５がすっきりとした印象の包装形態を実現することができる。しかも、表面フラップ２３に充分な面積の印刷又は印字領域を確保することができる。
このような包装形態は、図７（ｂ）に示すように、耳部２０の長さＬ１を、被包装物１０の各側面１５，１５の両端縁１５ａ、１５ａの長さＬ０よりも短く設定することで実現することができる。
かかる包装形態も、第１折込みフラップ２１を被包装物１０の両側面１５，１５に向けてそれぞれ折り込んだ後、側部折込みフラップ２２，２２を、頂点ｃ（被包装物１０の角部）から底辺ｂ（中間部を山折りしたときの稜線）に引いた垂線ａに沿って、谷折りして折り込んでいくことにより、形成することができる。 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).

また、上述した実施形態では、耳部２０の下面部分を第１折込みフラップ２１に設定したが、これに限定されず、耳部２０の上面部分や側面部分のいずれかを第１折込みフラップ２１に設定してもよい。 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.
