Abstract

<P>PROBLEM TO BE SOLVED: To provide a paper box whose lid can be securely kept open in an upright position. <P>SOLUTION: Of the six faces of the paper box 1, an upper face 16, or an upper wall 16, is used to provide the lid 28 by forming perforations 27 along the shape of the lid 28, except one side at its basal end, which serves as a crease 29. Thus, the paper box 1 having the lid 28 bendable along the crease 29 is obtained. In such a paper box 1, the lid 28 is provided with a pair of tongues 31 and 32, right and left, which are formed so as to project back from the crease 29. Locking parts 33 and 34 for locking the tongues 31 and 32, respectively, are formed in the upper wall 16. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、菓子や化粧品や小物などを収容する蓋付きの紙箱に関する。 The present invention relates to a paper box with a lid that accommodates confectionery, cosmetics, accessories, and the like.

従来の直方体状に組み立てた紙箱において、上側壁から前壁にわたって略Ｕ字状の切目を設けて、切目のＵ字部分に蓋を形成し、該蓋を後端縁に設けた折目に沿って折曲げ可能とした紙箱が公知となっている。このような紙箱は、折目部分を谷折りに折り曲げて蓋とし、上側壁に対し起立状態とすることで、開放されるようになっているが、蓋を手で支えるなどしないと、起立状態に保持することができず、すぐに閉鎖されるようになっていた。そのため、紙箱に収容したものを繰り返して取り出すような場合には、毎回蓋を開かなければならなかった。 In a conventional paper box assembled in a rectangular parallelepiped shape, a substantially U-shaped cut is provided from the upper side wall to the front wall, a lid is formed on the U-shaped part of the cut, and the lid is provided along the crease provided on the rear edge. Paper boxes that can be bent are known. Such a paper box is designed to be opened by folding the fold part into a valley fold to make it a lid and standing up with respect to the upper side wall. Could not be held in and was supposed to be immediately closed. Therefore, the lid had to be opened every time when the items stored in the paper box were repeatedly taken out.

そこで、紙箱の蓋を上側壁に起立状態に保持するための技術が提案されている。この技術においては、蓋に折目よりも後方に突出する舌片が形成され、この舌片の下面に重なり合う固定片が形成される。そして、蓋の開放に伴い固定片が舌片により押し下げられ、蓋の開度が９０度を越えると、固定片の復元力により蓋が後傾方向に付勢され、この付勢力が折目において作用する閉鎖方向の力と均衡し、蓋の起立状態が保持されるようになっている（例えば、特許文献１参照。）。
特開平１０−１８１７３９号公報 Therefore, a technique for holding the lid of the paper box upright on the upper side wall has been proposed. In this technique, a tongue piece that protrudes rearward from the fold is formed on the lid, and a fixed piece that overlaps the lower surface of the tongue piece is formed. When the lid is opened, the fixing piece is pushed down by the tongue piece, and when the opening degree of the lid exceeds 90 degrees, the lid is urged backward by the restoring force of the fixing piece, and this urging force is applied at the fold. In balance with the acting force in the closing direction, the standing state of the lid is maintained (for example, see Patent Document 1).
Japanese Patent Laid-Open No. 10-181739

しかし、従来の紙箱においては、蓋を折目に沿って折り曲げて開いたときに、舌片を固定片に重なり合わせて蓋を起立状態に保持する構成のため、誤って手が蓋に軽く触れたときなどに、簡単に蓋が閉じてしまうという不具合があった。また、固定片の部分には切込みを設けなければならず、折り曲げ、貼り合わせの工程が増加していた。 However, in the conventional paper box, when the lid is folded along the crease and opened, the tongue is overlapped with the fixed piece and the lid is held upright. In some cases, the lid could easily close. In addition, the fixing piece portion must be provided with a cut, and the number of bending and bonding steps has increased.

本発明の解決しようとする課題は以上の如くであり、次にこの課題を解決するための手段を説明する。 The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

即ち、請求項１においては、紙箱の６面のうちの上側壁に、一辺を残して切目を設けて蓋を形成し、該蓋の基端側縁の一辺を折目として、該折目に沿って折曲可能に形成した蓋を備える紙箱において、前記蓋に折目よりも後方へ突出する左右一対の舌片を形成し、各舌片を係止する係止片を上側壁に形成したものである。 That is, in claim 1, a cover is formed by providing a cut on the upper side wall of the six surfaces of the paper box, leaving one side, and one side of the base end side edge of the cover is defined as a fold. In a paper box provided with a lid that can be bent along, a pair of left and right tongue pieces projecting rearward from the fold are formed on the lid, and a locking piece for locking each tongue piece is formed on the upper side wall. Is.

請求項２においては、前記上側壁に設けた折目を後方に突出する平面視円弧状に形成したものである。 According to a second aspect of the present invention, the fold provided on the upper side wall is formed in a circular arc shape in plan view protruding rearward.

本発明の効果として、以下に示すような効果を奏する。 As effects of the present invention, the following effects can be obtained.

請求項１においては、紙箱の６面のうちの上側壁に、一辺を残して切目を設けて蓋を形成し、該蓋の基端側縁の一辺を折目として、該折目に沿って折曲可能に形成した蓋を備える紙箱において、前記蓋に折目よりも後方へ突出する左右一対の舌片を形成し、各舌片を係止する係止片を上側壁に形成したことから、蓋を開けるべく折目に沿って折り曲げたときに、舌片を係止片に係止させて、上側壁に蓋を確実に起立状態に保つことができる。そのため、例えば手が軽く触れた程度では蓋が閉じることはない。また、切り込みのみの構成で舌片と係止片を構成できるので、製作が簡単で、更なる折り曲げ工程や貼り付け工程が不要であり、安価に起立状態するための部材を構成できる。 In claim 1, the upper side wall of the six surfaces of the paper box is provided with a cut leaving a side to form a lid, and one side of the base side edge of the lid is taken as a fold along the fold. In a paper box having a lid formed so as to be bendable, a pair of left and right tongues protruding rearward from the fold are formed on the lid, and a locking piece for locking each tongue piece is formed on the upper side wall. When the tongue is bent along the fold to open the lid, the tongue piece can be locked to the locking piece, so that the lid can be reliably kept upright on the upper side wall. Therefore, for example, the lid does not close when the hand is lightly touched. In addition, since the tongue piece and the locking piece can be configured only by the notch, it is easy to manufacture, does not require a further bending step or affixing step, and can constitute a member for standing up at a low cost.

請求項２においては、前記上側壁に設けた折目を後方に突出する平面視円弧状に形成したことから、蓋を開いたときに舌片が僅かに前方に突出し、係止片に係止しやすくなる。また、蓋を開いたときに折目の両側が持ち上げられるため、閉じ方向へ戻す力が従来の折目が直線状のときに比べて大きくなり、繰り返し蓋を開け閉めしても中途半端な開け位置で止まることもない。 In claim 2, since the fold provided on the upper side wall is formed in a circular arc shape in a plan view protruding backward, the tongue piece slightly protrudes forward when the lid is opened and is locked to the locking piece. It becomes easy to do. Also, since both sides of the fold are lifted when the lid is opened, the force to return to the closing direction is greater than when the conventional fold is linear, and even if the lid is opened and closed repeatedly, halfway opening It does not stop at the position.

次に、発明の実施の形態を説明する。

FIG. 5 is a plan view of the paper box, and FIG. 6 is a perspective view of the locking portion.

本発明の一実施例に係る紙箱１は一枚の紙箱用台紙１ａから構成されている。紙箱の６面のうち図２に示すように、上面を上側壁１６、蓋２８を開放する側を前として、前面を前側壁２２、後面を後側壁６、左右の側面を左右側壁１９・２０、底面を底板２として説明する。 A paper box 1 according to an embodiment of the present invention is composed of a single paper box mount 1a. As shown in FIG. 2, among the six surfaces of the paper box, the upper surface is the upper side wall 16, the side where the lid 28 is opened is the front, the front surface is the front side wall 22, the rear surface is the rear side wall 6, and the left and right side surfaces are the left and right side walls 19. The bottom surface will be described as the bottom plate 2.

図１に示すように、該台紙１ａには、四角形状の底板２と、底板２の前側縁に折目３を介して連設される前接合片４と、底板２の左右側縁に折目７・８を介して連設される左右接合片９・１０と、底板２の後側縁に折目５を介して連設される後側壁６と、後側壁６の左右側縁に折目１１・１２を介して連設される左右折曲片１３・１４と、後側壁６の後側縁に折目１５を介して連設される上側壁１６と、上側壁１６の左右側縁に折目１７・１８を介して連設される左右側壁１９・２０と、上側壁１６の後側縁に折目２１を介して連設される前側壁２２と、前側壁２２の左右側縁に折目２３・２４を介して連設される左右折曲片２５・２６とが備えられている。 As shown in FIG. 1, the mount 1 a includes a rectangular bottom plate 2, a front joining piece 4 connected to the front side edge of the bottom plate 2 via a fold 3, and folded to the left and right side edges of the bottom plate 2. Folded to the left and right side edges of the rear side wall 6, the left and right joint pieces 9, 10 connected via the eyes 7, 8, the rear side wall 6 connected to the rear side edge of the bottom plate 2 via the fold 5. Left and right bent pieces 13 and 14 provided continuously through the eyes 11 and 12, an upper side wall 16 connected to the rear side edge of the rear side wall 6 through the fold 15, and left and right side edges of the upper side wall 16 Left and right side walls 19, 20 connected to each other through the folds 17, 18, a front side wall 22 connected to the rear side edge of the upper side wall 16 via the folds 21, and left and right side edges of the front side wall 22 And left and right bent pieces 25 and 26 connected to each other through the folds 23 and 24, respectively.

また、前記台紙１ａには、上側壁１６から前側壁２２にわたって一辺を残して略Ｕ字型に切目２７が点線状に設けられ、該切目２７で囲まれた部分が蓋２８とされている。そして、該蓋２８の基端側縁の一辺が折目２９とされ、図５に示すように、該折目２９が後方（開放側と反対方向の後側壁６側）に突出する平面視円弧状に形成されている。該折目２９には他の折目と同様に押し型等で線状に窪みを形成して折り曲げ易くし、更に、該折目２９には蓋２８を千切って取り去ることが可能なように目の粗い切目を施している。 Further, the mount 1a is provided with a substantially U-shaped cut line 27 in a dotted line shape, leaving one side from the upper side wall 16 to the front side wall 22, and a portion surrounded by the cut line 27 is a lid 28. Then, one side edge of the base end side edge of the lid 28 is a fold 29, and as shown in FIG. 5, the fold 29 protrudes rearward (rear side wall 6 side opposite to the open side) in plan view. It is formed in an arc shape. Like the other folds, the fold 29 is formed into a linear depression with a pressing die or the like so that it can be bent easily. Further, the fold 29 can be removed by cutting off the lid 28. A rough cut is made.

蓋２８の基端側縁の両側部、つまり、前記折目２９の両側には、折目２９よりも後側壁６側へ突出する一対の舌片３１・３２が形成され、該舌片３１・３２の両外側に該舌片３１・３２を係止するための一対の係止片３３・３４が上側壁１６に形成されている。該舌片３１・３２と係止片３３・３４は切り込みにより同時に形成され、舌片３１・３２の外側の凹部が上側壁１６において凸状の係止片３３・３４として形成され、両者は蓋２８を折り曲げることにより現出する。 A pair of tongue pieces 31, 32 projecting toward the rear side wall 6 from the fold 29 is formed on both sides of the base side edge of the lid 28, that is, on both sides of the fold 29. A pair of locking pieces 33 and 34 for locking the tongue pieces 31 and 32 are formed on the upper side wall 16 on both outer sides of 32. The tongue pieces 31 and 32 and the locking pieces 33 and 34 are simultaneously formed by cutting, and the recesses on the outer side of the tongue pieces 31 and 32 are formed as convex locking pieces 33 and 34 on the upper side wall 16. It appears by bending 28.

前記係止片３３・３４は折目２９の左右略延長線上に配置され、舌片３１・３２に隣接して切目２７よりも内側（蓋２８側）に突出するように形成されている。詳細に説明すると、折目２９の両端の左右側方に係止片３３・３４が位置し、折目２９の両側端は係止片３３・３４の前端（前側壁２２側の端部）よりも後方（後側壁６側）に位置させて、蓋２８を折り曲げたときに舌片３１・３２と係止片３３・３４が重なるようにしている。 The locking pieces 33 and 34 are disposed on substantially the left and right extension lines of the fold line 29 and are formed adjacent to the tongue pieces 31 and 32 so as to protrude inwardly (on the lid 28 side) from the cut line 27. More specifically, the locking pieces 33 and 34 are located on the left and right sides of both ends of the fold 29, and both side ends of the fold 29 are from the front ends (ends on the front side wall 22 side) of the locking pieces 33 and 34. Also, the tongue pieces 31 and 32 and the locking pieces 33 and 34 are overlapped when the lid 28 is bent.

また、蓋２８の先端に係止片３５が形成されるとともに、該係止片３５を差込可能とする差込孔３６が前接合片４に形成されている。 Further, a locking piece 35 is formed at the tip of the lid 28, and an insertion hole 36 through which the locking piece 35 can be inserted is formed in the front joining piece 4.

このように構成した台紙１ａを箱状に組み立てる場合、底板２の前後側縁に連設される前接合片４と後側壁６とをそれぞれ折目３・５に沿って内側に折り曲げ、上側壁１６を折目１５に沿って折り曲げ、更に前側壁２２を折目２１に沿って折り曲げて、その内側に配置した前接合片４に接着剤又は両面テープなどで貼り付ける。そして、後側壁６の左右折曲片１３・１４を折目１１・１２に沿って内側に折り曲げるとともに、前側壁２２の左右折曲片２５・２６を折目２３・２４に沿って折り曲げ、続いて底板２の左右接合片９・１０をそれぞれ折目７・８に沿って内側に折り曲げて前記折曲片１３・１４・２５・２６に重ね合わせ、最後に上側壁１６の左右側壁１９・２０を折目１７・１８に沿って折り曲げて、その内側に配置した接合片９・１０に接着剤又はテープなどで貼り付けることで、図２に示すように、紙箱１が組立状態に構成される。 When the mount 1a thus configured is assembled in a box shape, the front joining piece 4 and the rear side wall 6 connected to the front and rear side edges of the bottom plate 2 are folded inward along the fold lines 3 and 5, respectively, 16 is bent along the fold line 15, and the front side wall 22 is further folded along the fold line 21, and is attached to the front joining piece 4 disposed inside thereof with an adhesive or a double-sided tape. Then, the left and right bent pieces 13 and 14 of the rear side wall 6 are bent inward along the folds 11 and 12, and the left and right bent pieces 25 and 26 of the front side wall 22 are bent along the folds 23 and 24. Then, the left and right joining pieces 9 and 10 of the bottom plate 2 are folded inward along the folds 7 and 8 respectively and overlapped with the bent pieces 13, 14, 25 and 26, and finally the left and right side walls 19 and 20 of the upper side wall 16. Is folded along the folds 17 and 18 and attached to the joining pieces 9 and 10 disposed on the inner side with an adhesive or a tape, whereby the paper box 1 is assembled as shown in FIG. .

そして、図３に示すように、蓋２８を切目２７に沿って前側壁２２及び上側壁１６から切り離し、折目２９に沿って折り曲げて起立させることで、紙箱１が開放状態となる。このようにして蓋２８を開く際、舌片３１・３２も蓋２８に伴って傾動し、蓋２８の開度が１８０度を越えると、舌片３１・３２が係止片３３・３４を乗り越えて、その下方から上方へと移動する。これにより、蓋２８が閉じ方向へ移動しても、図６に示すように、舌片３１（３２）が係止片３３（３４）に係止され、蓋２８が起立した状態に保持される。 Then, as shown in FIG. 3, the lid 28 is separated from the front side wall 22 and the upper side wall 16 along the cut line 27, bent along the fold line 29, and stood up, whereby the paper box 1 is opened. When the lid 28 is opened in this way, the tongue pieces 31 and 32 also tilt with the lid 28, and when the opening degree of the lid 28 exceeds 180 degrees, the tongue pieces 31 and 32 get over the locking pieces 33 and 34. And move from below to above. Thus, even when the lid 28 moves in the closing direction, the tongue piece 31 (32) is locked to the locking piece 33 (34) and the lid 28 is held upright as shown in FIG. .

蓋２８を後上方へ折り曲げるとき、折目２９が後方に突出する円弧状に形成しているため、折目２９両側に位置する舌片３１・３２は上方へ持ち上げられる。つまり、蓋２８の回動支点は左右中央が低く、左右両側は若干高くなるため、舌片３１・３２先端が係止片３３・３４に近づき乗り上げることで係合するようになる。さらに、舌片３１・３２を構成する切目端の位置は折目２９の両端と一致し、蓋２８を持ち上げると折目２９に沿って折り曲げられるが、この折り曲げ時に蓋２８の回動支点は切目端よりも後方となる。つまり、折り曲げるときに切目端より更に前方に台紙を破りながら曲げることはない。よって、回動支点が係止片３３・３４の後部位置となり、蓋２８の回動時に舌片３１・３２と係止片３３・３４が平面視で重なり、１８０度を越えると、舌片３１・３２が係止片３３・３４を乗り越えることになる。 When the lid 28 is folded rearward and upward, since the fold 29 is formed in an arc shape protruding backward, the tongue pieces 31 and 32 positioned on both sides of the fold 29 are lifted upward. In other words, the pivotal fulcrum of the lid 28 is low at the center in the left and right sides and slightly higher on the left and right sides, so that the tips of the tongue pieces 31 and 32 approach the locking pieces 33 and 34 to engage with each other. Further, the positions of the cut ends constituting the tongue pieces 31 and 32 coincide with both ends of the fold 29, and when the lid 28 is lifted, the lid 28 is folded along the fold 29. Behind the edge. That is, when bending, it is not bent while tearing the mount further forward than the cut edge. Therefore, the rotation fulcrum becomes the rear position of the locking pieces 33 and 34. When the lid 28 is rotated, the tongue pieces 31 and 32 and the locking pieces 33 and 34 overlap in a plan view. -32 will get over the locking pieces 33, 34.

また、舌片３１・３２を係止片３３・３４に係止させて、蓋２８を起立させた状態から、舌片３１・３２を係止片３３・３４の下方へと移動させて係止状態を解除し、蓋２８を折目２９に沿って折り曲げ、その先端に形成した係止片３５を前接合片４に形成した差込孔３６に差し込むことで、図４に示すように、紙箱１が閉鎖状態となる。 Further, the tongue pieces 31 and 32 are engaged with the engagement pieces 33 and 34, and the tongue pieces 31 and 32 are moved downward from the engagement pieces 33 and 34 from the state in which the lid 28 is erected. The state is released, the lid 28 is bent along the fold line 29, and the locking piece 35 formed at the tip thereof is inserted into the insertion hole 36 formed in the front joining piece 4, so that a paper box is formed as shown in FIG. 1 is closed.

以上のように、紙箱１の６面のうちの上側壁１６に、一辺を残して切目２７を設けて蓋２８を形成し、該蓋２８の基端側縁の一辺を折目２９として、該折目２９に沿って折曲可能に形成した蓋２８を備える紙箱１において、前記蓋２８に折目２９よりも後方へ突出する左右一対の舌片３１・３２を形成し、各舌片３１・３２を係止する係止片３３・３４を上側壁１６に形成したので、蓋２８を開けるべく折目２９に沿って折り曲げたときに、舌片３１・３２を係止片３３・３４に係止させて、上側壁１６に蓋２８を確実に起立状態に保つことができる。そのため、例えば手が軽く触れた程度では蓋が閉じることはない。また、切り込みのみの構成で舌片３１・３２と係止片３３・３４を構成できるので、製作が簡単で、更なる折り曲げ工程や貼り付け工程が不要であり、安価に起立状態するための部材を構成できる。 As described above, the upper wall 16 of the six faces of the paper box 1 is provided with a cut 27 with one side left to form a lid 28, and one side of the base side edge of the lid 28 is defined as a fold 29. In the paper box 1 including the lid 28 formed to be foldable along the fold 29, a pair of left and right tongue pieces 31, 32 protruding rearward from the fold 29 is formed on the lid 28, and each tongue piece 31. Since the locking pieces 33 and 34 for locking 32 are formed on the upper side wall 16, the tongue pieces 31 and 32 are engaged with the locking pieces 33 and 34 when folded along the fold 29 to open the lid 28. The lid 28 can be reliably kept upright on the upper side wall 16. Therefore, for example, the lid does not close when the hand is lightly touched. In addition, since the tongue pieces 31 and 32 and the locking pieces 33 and 34 can be configured only by the notches, the manufacture is simple, no further bending process or attaching process is required, and a member for standing up at a low cost. Can be configured.

また、前記上側壁１６に設けた折目２９を後方に突出するように平面視円弧状に形成したので、蓋２８を開いたときに舌片３１・３２が僅かに前方に突出し、係止片３３・３４に係止しやすくなる。また、蓋２８を開いたときに折目２９の両側が持ち上げられるため、閉じ方向へ戻す力が従来の折目が直線状のときに比べて大きくなり、繰り返し蓋２８を開け閉めしても中途半端な開け位置で止まることもない。 Further, since the fold 29 provided on the upper side wall 16 is formed in an arc shape in plan view so as to protrude rearward, the tongue pieces 31 and 32 protrude slightly forward when the lid 28 is opened, and the locking piece It becomes easy to lock to 33 and 34. Further, since both sides of the fold 29 are lifted when the lid 28 is opened, the force to return to the closing direction becomes larger than when the conventional fold is linear, and even if the lid 28 is repeatedly opened and closed It does not stop at the half-open position.
