Description

本発明は、例えば、焼酎、清酒等の瓶１本ずつ包装する包装用紙箱に関する。 The present invention relates to a packaging paper box for packaging, for example, bottles of shochu, sake and the like one by one.

焼酎、清酒等の瓶は、７２０ｍｌ，９００ｍｌ，１８００ｍｌ等が一般的であり、店頭で販売する際には、顧客が瓶を手に取ってラベルに表示された内容物の情報等を確認できるように未包装の瓶のまま陳列されている場合が多い。焼酎、清酒等を顧客が贈答用等として購入する場合、店員に紙箱包装を希望することを告げると、店員が店舗に用意されている包装用紙箱を取り出し、瓶を包装用紙箱に収納して顧客に手渡ししている。 Bottles for shochu, sake, etc. are generally 720ml, 900ml, 1800ml, etc. When selling at the store, customers can check the information etc. displayed on the label by picking up the bottle In many cases, they are displayed as unpackaged bottles. When a customer purchases shochu, sake, etc. for gifts etc., tells the store clerk that he wants to wrap the paper box, and the store clerk takes out the wrapping paper box prepared in the store and stores the bottle in the wrapping paper box. Handing it over to the customer.

焼酎、清酒等の瓶を包装する包装用紙箱は、瓶を立てに１本ずつ収納できるように、上部に蓋部を有する縦長の直方体形状が一般的であるが、包装用紙箱は、店舗で保管する際に嵩張らないように扁平状に折り畳まれる折り畳み式である。しかも、包装用紙箱は必要に応じてワンタッチで組立てられると共に、組立て後は、糊や粘着テープを用いることなく立体的箱形状に保てるように構成されている。 Packaging paper boxes that wrap bottles such as shochu, sake, etc. are generally in the shape of a rectangular parallelepiped with a lid on the top so that bottles can be stored one by one. It is a foldable type that is folded flat so as not to be bulky during storage. In addition, the packaging paper box can be assembled with a single touch if necessary, and can be maintained in a three-dimensional box shape without using glue or adhesive tape after assembly.

図１１は従来の底組込み式包装用紙箱の展開図、図１２は組立て状態の底部を示し、（ａ）は内底面図、（ｂ）は外底面図である。図１１及び図１２に示すように、厚紙にコーティングを施したコートボール、段ボール等によって形成された六角筒形状の箱主体５０は、同一幅、同一長さの長方形状の第１側板〜第６側板５１〜５６が第１山折り線〜第５山折り線５７ａ〜５７ｅを介して連設されている。さらに、第１側板５１には山折り線５８を介して糊代片５９が連設されている。 FIG. 11 is a developed view of a conventional bottom built-in packaging paper box, FIG. 12 shows a bottom portion in an assembled state, (a) is an inner bottom view, and (b) is an outer bottom view. As shown in FIG. 11 and FIG. 12, hexagonal cylindrical box main body 50 formed by coated balls, corrugated cardboard, etc., coated on cardboard, is a rectangular first side plate to sixth plate having the same width and the same length. Side plates 51 to 56 are connected to each other via first to fifth fold lines 57a to 57e. Further, a paste margin piece 59 is continuously provided on the first side plate 51 via a mountain fold line 58.

箱主体５０の底部６０側には第１側板〜第６側板５１〜５６と山折り線５１ａ〜５１ｆを介して第１底部片〜第６底部片６１〜６６が連設されている。第1底部片６１〜第６底部片６６は同一形状であり、山折り線５１ａ〜５１ｆを底辺とする略直角三角形状に形成されている。 First to sixth bottom pieces 61 to 66 are continuously provided on the bottom 60 side of the box main body 50 via first to sixth side plates 51 to 56 and mountain fold lines 51a to 51f. The first bottom piece 61 to the sixth bottom piece 66 have the same shape, and are formed in a substantially right triangle shape with the mountain fold lines 51a to 51f as the bottoms.

前記箱主体５０は、第１山折り線〜第５山折り線５７ａ〜５７ｅ及び山折り線５８を山折りし、第６側板５６を糊代片５９に糊付けすることにより六角筒形状に形成される。また、第１側板〜第６側板５１〜５６に対して山折り線５１ａ〜５１ｆから山折りして第１底部片〜第６底部片６１〜６６を箱主体５０の内部に折り込み、第１底部片６１の先端部の上に対して第２底部片６２を重ね、さらに第２底部片６２の先端部の上に対して第３底部片６３を重ねる要領で順次重ね、最終的に第６底部片６６の先端部を第１底部片６１の下（内側）に重ねることにより、底部６０が形成されている。 The box main body 50 is formed in a hexagonal cylinder shape by folding the first fold line to the fifth fold line 57a to 57e and the fold line 58, and gluing the sixth side plate 56 to the glue margin piece 59. The Further, the first bottom plate to the sixth side plates 51 to 56 are folded from the mountain fold lines 51a to 51f to fold the first bottom piece to the sixth bottom pieces 61 to 66 into the inside of the box main body 50. The second bottom piece 62 is overlaid on the top end of the piece 61, and the third bottom piece 63 is overlaid on the top end of the second bottom piece 62 one after another. The bottom portion 60 is formed by overlapping the tip portion of the piece 66 below (inner side) the first bottom piece 61.

前述のように構成された箱主体５０は、不使用時には扁平状に折り畳み可能であるが、第１底部片〜第６底部片６１〜６６を山折り線５１ａ〜５１ｆから山折りせずに箱主体５０の底部６０から外方に突出させた状態にすることにより、扁平状に折り畳みできる。 Although the box main body 50 configured as described above can be folded flat when not in use, the first bottom piece to the sixth bottom pieces 61 to 66 are not folded from the mountain fold lines 51a to 51f. By making it protrude outward from the bottom 60 of the main body 50, it can be folded flat.

さらに、焼酎、清酒等の瓶１本ずつ包装することが可能で、しかもワンタッチで組立て折り畳みが可能な六角筒形状の包装用紙箱が知られている（例えば、特許文献１参照。）。
実用新案登録第３１１０５２３号公報 Furthermore, a hexagonal cylindrical packaging paper box that can be packaged one by one, such as shochu, sake, etc., and can be assembled and folded with a single touch is known (for example, see Patent Document 1).

しかし、図１１及び図１２に示す包装用紙箱は、箱主体５０の底部６０を構成する第１底部片〜第６底部片６１〜６６が、その先端部のみが重なる構造であり、強度的に弱く、例えば焼酎、清酒等の瓶１本ずつ包装するには不向きである。また、箱主体５０の組立て時には第１底部片〜第６底部片６１〜６６を山折り線５１ａ〜５１ｆから山折りして箱主体５０の内部に折り込む面倒な操作が必要となる。
また、前記特許文献１は、箱主体の六角筒形状の底部開口を第１の底面片と第２の底面片の２枚の底面片で閉塞し、第１の底面片と第２の底面片の噛合部が互いに噛み合うようにした構造である。従って、繰り返し使用して噛合部の噛み合いが弱くなると底部が抜ける虞があり、例えば焼酎、清酒等の瓶１本ずつ包装するには不向きである。
本発明は、前記事情に着目してなされたもので、その目的とするところは、第１底部片と第４底部片とを結合した構造であり、繰り返し使用しても耐久性があり、また、組立て、折り畳みがワンタッチで行え、例えば焼酎、清酒等の瓶１本ずつ包装する場合に好適な包装用紙箱を提供することにある。 However, the packaging paper box shown in FIGS. 11 and 12 has a structure in which the first bottom piece to the sixth bottom pieces 61 to 66 constituting the bottom portion 60 of the box main body 50 are overlapped only at the front end portions, and the strength is high. It is weak and unsuitable for packaging bottles of shochu, sake, etc. one by one. Further, when the box main body 50 is assembled, a troublesome operation of folding the first bottom piece to the sixth bottom piece 61 to 66 from the mountain fold lines 51a to 51f and folding them into the box main body 50 is required.
Further, in Patent Document 1, a box-shaped hexagonal cylindrical bottom opening is closed with two bottom pieces, a first bottom piece and a second bottom piece, and a first bottom piece and a second bottom piece. This is a structure in which the meshing portions mesh with each other. Therefore, if the meshing of the meshing part becomes weak after repeated use, the bottom part may come off, which is unsuitable for packaging bottles of shochu, sake, etc. one by one.
The present invention has been made by paying attention to the above circumstances, and its object is a structure in which the first bottom piece and the fourth bottom piece are combined, and is durable even after repeated use. An object of the present invention is to provide a packaging paper box that can be assembled and folded with one touch and is suitable for packaging, for example, shochu and sake bottles one by one.
