【発明の属する技術分野】
この発明は、靴箱等として、扁平な折畳状態から組み立てて使用される厚紙製の蓋付き箱に関するものである。
【０００２】
【従来の技術】
例えば、靴店で靴を包装する際には、図１１に示すように、底面板５３に前面板５４、一対の側面板５５及び後面板５６を連設して身５１を構成し、後面板５６に繋がる天面板５７に蓋前板５８及び一対の蓋側板５９を連設して身５１に被さる蓋５２を構成した靴箱を使用する。
【０００３】
この靴箱の身５１は、前面板５４と側面板５５及び後面板５６と側面板５５とを斜谷折線ｄに沿って折り曲げられる連結片６１，６２を介してそれぞれ繋ぎ、前面板５４及び側面板５５から延出した重合板６３，６４を内側へ折り曲げ、前面板５４と重合板６３とで連結片６１を抱き込むことにより保形する。
【０００４】
また、蓋５２は、蓋前板５８と蓋側板５９とを斜谷折線ｅに沿って折り曲げられる連結片６５を介して繋ぎ、蓋前板５８から延出した重合板６６を内側へ折り曲げ、蓋前板５８と重合板６６とで連結片６５を抱き込むことにより保形する。
【０００５】
【発明が解決しようとする課題】
しかしながら、上記のような靴箱は、組み立てに手間がかかり、店頭で迅速に靴を包装できないという問題がある。また、重合板を要することから、製造に多量の用紙を消費するという問題もある。
【０００６】
そこで、この発明は、折畳状態からの組み立てが容易で、少量の材料で製造できる蓋付き箱を提供することを課題とする。
【０００７】
【課題を解決するための手段】
上記課題を解決するため、この発明は、底面板、前面板、一対の側面板及び後面板を連設して身を構成し、その後面板に繋がる天面板に蓋前板及び一対の蓋側板を連設して身に被さる蓋を構成し、扁平な折畳状態から組み立てられるようにした蓋付き箱において、底面板の前角から前面板の端縁に至る斜山折線と、底面板の後角から側面板の端縁に至る斜谷折線と、天面板の前角から蓋前板の端縁に至る斜山折線とを設け、折畳状態では、前面板、両側面板及び蓋前板をそれぞれ斜山折線、斜谷折線及び斜山折線に沿って折り曲げ、底面板と後面板とが重なるように二つ折りにすることとしたのである。
【０００８】
この蓋付き箱は、連結片の折り曲げや抱込等の作業を要することなく、扁平な折畳状態から迅速に組み立てることができ、重合板が不要であることから、少量の用紙で製造できる。
【０００９】
なお、前記蓋前板の斜山折線に代えて、天面板の前角から蓋側板の端縁に至る斜谷折線を設け、折畳状態では、この斜谷折線に沿って蓋側板を折り曲げるようにしてもよい。
【００１０】
また、前記蓋前板及び一対の蓋側板を下方へ延長し、組立時に蓋前板が前面板を覆うようにすると、前方の稜線が補強されて、積上時の剛性が向上し、蓋前板の端縁が見えにくくなって、美粧性が向上する。
【００１１】
【発明の実施の形態】
まず、この発明の第１実施形態を図１乃至図５に基づいて説明する。
【００１２】
この蓋付き箱のブランクは、図１に示すように、底面板３に前面板４、一対の側面板５及び後面板６を連設し、また後面板６に繋がる天面板７に蓋前板８及び一対の蓋側板９を連設し、前面板４、後面板６及び蓋前板８の両側縁からそれぞれ継代１１，１２，１３を延出したものとされ、蓋側板９の端縁は前下がりになるように傾斜し、蓋前板８は前面板４を覆える大きさとなっている。
【００１３】
また、このブランクには、底面板３の前角から前面板４の端縁に至る斜山折線ａと、底面板３の後角から側面板５の端縁に至る斜谷折線ｂと、天面板７の前角から蓋前板８の端縁に至る斜山折線ｃとが、水平及び垂直方向に対して４５°の角度で傾斜するように設けられている。
【００１４】
ところで、この例では、斜山折線ａ，ｃを罫線とし、斜谷折線ｂを罫線にミシン目状の切目を入れたリード罫としているが、これらは、斜谷折線ｂが逆折しやすいように、罫線、ミシン目、半切線等を適宜組み合わせて形成すればよい。
【００１５】
このようなブランクから蓋付き箱を形成するには、底面板３から前面板４、側面板５及び後面板６を起こして、継代１１を側面板５の前端部内面に貼着し、継代１２を側面板５の斜谷折線ｂより後部の内面に貼着し、また、天面板７から蓋前板８及び蓋側板９を起こし、継代１３を蓋側板９の前端部内面に貼着する。
【００１６】
そして、図２に示すように、前面板４、側面板５及び蓋前板８をそれぞれ斜山折線ａ、斜谷折線ｂ及び斜山折線ｃに沿って折り曲げ、底面板３と後面板６とが重なるように二つ折りにすると、この蓋付き箱は扁平に折り畳まれるので、輸送時や保管時に嵩張ることがない。
【００１７】
一方、このように扁平に折り畳んだ状態から蓋付き箱を組み立てるには、図３に示すように、底面板３から後面板６を起こし、図４に示すように、前面板４、両側面板５及び蓋前板８の折り曲げを伸ばして、身１及び蓋２を形成する。
【００１８】
そして、靴等の商品を身１に収納し、図５に示すように、蓋２を身１に被せるように閉じると、前面板４、両側面板５及び蓋前板８の屈曲が阻止され、この蓋付き箱は、確実に保形される。
【００１９】
このように、上記蓋付き箱は、従来例のような連結片の折り曲げや抱込等の作業を要することなく、扁平な折畳状態から迅速に組み立てることができる。
【００２０】
また、構造が簡単で、重合板が不要であることから、少量の用紙で製造でき、加工の手間もあまりかからない。
【００２１】
また、蓋前板８及び一対の蓋側板９を下方へ延長して、組立時に蓋前板８が前面板４を覆うようにしたので、前方の稜線が補強されて、積上時の剛性が向上するほか、蓋前板８の端縁が見えにくくなって、美粧性にも優れたものとなる。
【００２２】
次に、この発明の第２実施形態を図６乃至図１０に基づいて、上記第１実施形態との相違点を中心に説明する。
【００２３】
この蓋付き箱のブランクでは、前記蓋前板８の斜山折線ａに代えて、図６に示すように、天面板７の前角から蓋側板９の端縁に至る斜谷折線ｆが設けられ、蓋側板９は前端から後端まで長くなっている。
【００２４】
そして、このブランクを組み立てて折り畳む際には、図７に示すように、斜谷折線ｆに沿って蓋側板９を折り曲げるようにして、底面板３と後面板６とが重なるように二つ折りにする。
【００２５】
また、この折畳状態から蓋付き箱を組み立てる際には、図８に示すように、底面板３から後面板６を起こし、図９に示すように、前面板４、両側面板５及び蓋側板９の折り曲げを伸ばして、身１及び蓋２を形成する。
【００２６】
その後、靴等の商品を身１に収納し、図１０に示すように、蓋２を身１に被せるように閉じると、前面板４、両側面板５及び蓋側板９の屈曲が阻止され、この蓋付き箱は、確実に保形される。
【００２７】
このような蓋付き箱では、組立時に蓋２の正面となる蓋前板８に折線が現れないので、商品包装時の美観が向上する。
【００２８】
【発明の効果】
以上のように、この発明に係る蓋付き箱は、底面板から後面板を起こし、前面板、両側面板及び蓋前板又は蓋側板の折り曲げを伸ばすだけで、扁平な折畳状態から迅速に組み立てることができ、また、少量の材料で製造できるので、低コストで供給できる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cardboard box with a lid, which is used as a shoe box or the like when assembled from a flat folded state.
[0002]
[Prior art]
For example, when packing shoes in a shoe store, as shown in FIG. 11, a front plate 54, a pair of side plates 55, and a rear plate 56 are connected to a bottom plate 53 to form a body 51, and a rear plate is formed. A shoe box is used in which a lid front plate 58 and a pair of lid side plates 59 are connected to a top plate 57 connected to 56 to form a lid 52 that covers the body 51.
[0003]
The body 51 of the shoe box connects the front plate 54 and the side plate 55 and the rear plate 56 and the side plate 55 via connecting pieces 61 and 62 which are bent along the valley fold line d. The overlapping plates 63 and 64 extending from 55 are bent inward, and the front plate 54 and the overlapping plate 63 embrace the connecting piece 61 to maintain the shape.
[0004]
In addition, the lid 52 connects the lid front plate 58 and the lid side plate 59 via a connecting piece 65 that is bent along the inclined valley line e, and folds the superposed plate 66 extending from the lid front plate 58 inward, thereby forming a lid. The shape is maintained by holding the connecting piece 65 between the front plate 58 and the overlapping plate 66.
[0005]
[Problems to be solved by the invention]
However, the shoe box as described above has a problem that it takes time and effort to assemble, and that the shoe cannot be quickly packaged at a store. In addition, there is also a problem that a large amount of paper is consumed for production because a superposed plate is required.
[0006]
Therefore, an object of the present invention is to provide a box with a lid that can be easily assembled from a folded state and can be manufactured with a small amount of material.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides a body by connecting a bottom plate, a front plate, a pair of side plates and a rear plate in a row, and a lid front plate and a pair of lid side plates on a top plate connected to the rear plate. In a box with a lid, which is constructed so as to cover the body in a continuous manner and can be assembled from a flat folded state, a bent mountain fold line from the front corner of the bottom plate to the edge of the front plate, and the back of the bottom plate A valley fold line from the corner to the edge of the side plate and a sloping mountain fold line from the front corner of the top plate to the edge of the lid front plate are provided, and in the folded state, the front plate, both side plates and the lid front plate are They were folded along the skewed fold line, the valley fold line, and the skewed fold line, respectively, and were folded in two so that the bottom plate and the rear plate overlapped.
[0008]
This box with a lid can be quickly assembled from a flat folded state without the need to bend or embrace a connecting piece, and can be manufactured with a small amount of paper because a superposed plate is not required.
[0009]
In addition, instead of the sloping fold line of the lid front plate, a sloping fold line from the front corner of the top plate to the edge of the lid side plate is provided, and in the folded state, the lid side plate is bent along the sloping fold line. It may be.
[0010]
Further, if the lid front plate and the pair of lid side plates are extended downward so that the lid front plate covers the front plate at the time of assembly, the front ridgeline is reinforced, rigidity at the time of stacking is improved, and The edges of the board are less visible and the aesthetics are improved.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
First, a first embodiment of the present invention will be described with reference to FIGS.
[0012]
As shown in FIG. 1, the blank of the box with a lid is formed by connecting a front plate 4, a pair of side plates 5 and a rear plate 6 to a bottom plate 3, and a front plate 7 to a top plate 7 connected to the rear plate 6. 8 and a pair of lid side plates 9 are connected to each other, and passages 11, 12, and 13 are extended from both side edges of the front plate 4, the rear plate 6, and the front plate 8 of the lid. Is inclined so as to fall forward, and the front lid plate 8 is large enough to cover the front plate 4.
[0013]
The blank also includes a sloped fold line a extending from the front corner of the bottom plate 3 to the edge of the front plate 4, a sloped fold line b extending from the rear corner of the bottom plate 3 to the edge of the side plate 5, The inclined crease line c extending from the front corner of the face plate 7 to the edge of the lid front plate 8 is provided so as to be inclined at an angle of 45 ° with respect to the horizontal and vertical directions.
[0014]
By the way, in this example, the sloped fold lines a and c are ruled lines, and the sloping fold line b is a lead ruled line in which perforated cuts are formed in the ruled lines. In addition, a ruled line, a perforation, a half-cut line, or the like may be appropriately combined and formed.
[0015]
To form a box with a lid from such a blank, the front plate 4, the side plate 5, and the rear plate 6 are raised from the bottom plate 3, the passage 11 is attached to the inner surface of the front end of the side plate 5, The margin 12 is stuck on the inner surface of the side plate 5 behind the valley fold line b, the lid front plate 8 and the lid side plate 9 are raised from the top plate 7, and the passage 13 is stuck on the inner surface of the front end of the lid side plate 9. To wear.
[0016]
Then, as shown in FIG. 2, the front plate 4, the side plate 5, and the lid front plate 8 are bent along the ridge line a, the valley line b, and the ridge line c, respectively. When the box with the lid is folded in two so as to overlap with each other, the box with the lid is folded flat, so that it does not become bulky during transportation or storage.
[0017]
On the other hand, in order to assemble the box with the lid from the flat folded state, the rear plate 6 is raised from the bottom plate 3 as shown in FIG. 3, and the front plate 4 and the both side plates 5 as shown in FIG. The body 1 and the lid 2 are formed by extending the bending of the lid front plate 8.
[0018]
Then, when goods such as shoes are stored in the body 1 and the cover 2 is closed so as to cover the body 1 as shown in FIG. 5, the front plate 4, the side plates 5 and the cover front plate 8 are prevented from bending, The box with the lid is securely retained.
[0019]
As described above, the box with the lid can be quickly assembled from the flat folded state without the need for the operation of bending or embracing the connecting piece as in the conventional example.
[0020]
In addition, since the structure is simple and a superposed plate is not required, it can be manufactured with a small amount of paper, and the processing time is not much.
[0021]
Further, the front lid plate 8 and the pair of lid side plates 9 are extended downward so that the front lid plate 8 covers the front plate 4 during assembly, so that the front ridgeline is reinforced and rigidity during stacking is improved. In addition to the above, the edge of the lid front plate 8 is hardly seen, and the cosmetics are also excellent.
[0022]
Next, a second embodiment of the present invention will be described with reference to FIGS. 6 to 10, focusing on differences from the first embodiment.
[0023]
In the blank of the box with the lid, instead of the sloping fold line a of the front plate 8 of the cover, a valley fold line f extending from the front corner of the top plate 7 to the edge of the lid side plate 9 is provided as shown in FIG. The lid side plate 9 is elongated from the front end to the rear end.
[0024]
Then, when assembling and folding this blank, as shown in FIG. 7, the lid side plate 9 is bent along the inclined valley fold line f, so that the bottom plate 3 and the rear plate 6 are folded in two so as to overlap each other. I do.
[0025]
When assembling the box with the lid from the folded state, the rear plate 6 is raised from the bottom plate 3 as shown in FIG. 8, and as shown in FIG. The body 9 and the lid 2 are formed by extending the fold of 9.
[0026]
Thereafter, when products such as shoes are stored in the body 1 and the cover 2 is closed so as to cover the body 1 as shown in FIG. 10, the front plate 4, the side plates 5 and the cover side plate 9 are prevented from bending. The box with lid is securely retained.
[0027]
In such a box with a lid, since a folding line does not appear on the lid front plate 8 which is the front of the lid 2 at the time of assembly, the aesthetic appearance at the time of packaging the product is improved.
[0028]
【The invention's effect】
As described above, the box with the lid according to the present invention can be quickly assembled from the flat folded state only by raising the rear panel from the bottom panel and extending the bending of the front panel, both side panels, and the lid front panel or the lid side panel. And it can be manufactured with a small amount of material, so that it can be supplied at low cost.
