【0001】
【発明の属する技術分野】
本発明はキッチンペーパー、ティッシュペーパー、ビニル袋等、折り重ねられた枚葉シートや袋を収納し、簡便に内容物を取り出せる構造のカートンに関する。
【0002】
【従来の技術】
従来、キッチンペーパー、ティッシュペーパー、ビニル袋等、折り重ねられた枚葉シートや袋を収納し、天板部に周縁部を残した開口部を持ち、ここから前記折り重ねられた内容物を取り出すカートンが知られ、一般家庭の台所等で広く使用されている。これらカートン内に収納されたシート状内容物はZ字状に折り畳まれ、かつ端部が次のシート端部と重なるように積み重ねられているため、1枚のシートを取り出すと、次のシートが半立ち状態の掴みやすい状態になる便利なものである。
【0003】
ところで、前記収納カートンの中でも、台所等で使用することから水滴飛びや油跳ねなどから保護する意味もあり、開口部を持つ天板部を覆い隠す上蓋付きのものがあり、このタイプのカートンでは使用する際には前記上蓋を上側に引き起こし天板部を表面に晒してから内容物を取り出していた。しかしながら、前記上蓋は単に天板部後方の横折線部を支軸に開閉可能な構造となっているのみであるため、カートン材質の反力で閉じようとする動きをするため片方の手で上蓋を戻らないように抑えつつ、もう一方の手でシートを引き出さねばならず、煩雑な台所での家事仕事においてはもっと簡便に内容物を取り出すことできる上蓋カートンが要望されていた。
【0004】
【発明が解決しようとする課題】
本発明は、上蓋カートンにおいて、その開口部を覆う上蓋部が開けた状態を維持でき、かつ閉める場合でも簡単に閉じることができ、また閉じた状態では上蓋ロック機能も併せ持ち内容物を保護できる構成である開口維持構造付き上蓋カートンを提供することである。
【0005】
【課題を解決するための手段】
本発明において上記の課題を達成する為に、まず請求項1及び2の発明では、カートンの天板内または天板及び天板と連接する前面板に跨る一部に取り出し用の開口部を設け、収納時には後面外板から連接する上蓋部により前記開口部をロックし保護できる1枚のブランクからなる上蓋カートンにおいて、前記後面外板と前記上蓋部との境目で前記上蓋部の回転支軸となる横折線を有する横折線部に、前記横折線の代わりに、前記後面外板及び前記上蓋部の一部に及んで設けた2本1組の縦方向切込みと、この組同士の2本の縦方向切込みの間を前記横折線より上蓋寄りにずらして設けた横方向折線によって形成されるヒンジ部を少なくとも1ヶ所以上持つことを特徴とし、更にはそのヒンジ部が2本の縦直線切込みとこの間のずらした水平な折線とからなる略H字状形状のヒンジ部であることを特徴とする開口維持構造付き上蓋カートンである。
【0006】
また請求項3の発明では、前記前面板の前記開口部端に外方に折り曲げられて設けてある上蓋部係止片と、前記上蓋部内の上蓋前面板の先端部内側に折り曲げて設けてある上蓋前面板補強板とを有し、前記上蓋部係止片を前記上蓋前面板補強板に引っかけて前記上蓋部を閉じた状態にロックするのに用いられるロック機構を備えたことを特徴とする請求項1又は2記載の開口維持構造付き上蓋カートンである。
【0007】
【発明の実施の形態】
以下、本発明の実施の形態について図を用いて説明する。
〔実施例1〕
本発明の請求項1及び2に係る上蓋カートンの一例として、上蓋開き自立状態における見取り図を図1(a)に、上蓋部の開閉の動作を側面より見た側面断面図を図1(b)に、上蓋部回転支軸となる横折線部のヒンジ部の拡大図を図1(c)に示し、その上蓋カートンを1枚のブランクに展開した展開図を図2に示す。
【0008】
本発明の請求項1及び2に係る上蓋カートンは図2に示すように、直方体の胴部を構成する後面板(10),天板(20)、前面板(30)、底面板(40)、後面外板(50)とその左右側面部を構成する側面板(24R、24L)、(44R、44L)、及び上蓋部を構成する上蓋天板(60)、上蓋前面板(70)、上蓋側面板(64R、64L)の部材と組立時に相互の部材を接着させるための幾つかの接着片などを持ち、実線で図示される外形線、及び切込み線で型紙より打ち抜き機にて用意される。またこの打ち抜きの際に天板(20)と前面板(30)に跨る中央部には周縁部を残して内容物を取り出す開口部が同時に打ち抜かれ形成される。
【0009】
上蓋カートンの組立は以下のような手順でなされる。即ち、カートンの胴部は連接する各部材である後面板(10),天板(20)、前面板(30)、底面板(40)を図2内の1点鎖線で示される横折線で直角に折られ筒状直方体が形成された後、後面外板(50)の内側と後面板(10)外側が繋ぎ留めるため帯状に重ねてサック貼りされ、左右が閉じられていない筒状直方体が形成される。
【0010】
なお、天板(20)と前面板(30)の中央部には略4角形状の開口部が設られており、内容物を取り出すことができ、かつ不要に次のシート状内容物まで誤って出てこないよう、その左右両縁が適宜長さ分残されている。当実施例では略4角形状の開口部としているが、多角形状や長円状や楕円状の開口部でも何ら問題はない。また、前面板(30)の開口部上縁真ん中当たりには、閉じた状態時の上蓋部を簡便に係止するため上蓋部係止片(32)が上蓋部係止片補助切り込み(33)を持つ横折線(33a)にて折れ曲がり自由に設けられている。
【0011】
次に左右側面部のうち片方、例えば右側面部を前面板接着片(34R)、後面板接着片(54R)上に接着糊付けをし、各々縦折線で直角に折り曲げた後、側面板(44R)と接着させた後、更に側面板(44R)上に接着糊付けをし、側面板(24R)と接着させる。この片側が閉鎖された状態で、予め所定数量分、折重ねられたシート状内容物が側面より充填され、その後、他方の側面部も同様にして折り曲げられ、接着され、カートンの箱本体の組み立ては完成する。
【0012】
次に上蓋部(100)の組立を行うに当たっては、後面外板(50)と上蓋天板(60)との境目である横折線(51a)に平行で2〜3mm程上蓋天板(60)寄りにずらして設けるヒンジ部横折線(53h)が誤って同一直線上にならないよう、予め筋押し具などを用いて折り目を付けておく。このヒンジ部の横折線(53h)が上蓋部の回転支軸となる前記横折線(51a)から少しずらして設けることにより、後述する上蓋部の開閉動作時においては、上蓋部を開いた時に上蓋部が戻ろうとする動きに対し歯止めとなりヒンジ部の係止効果を生じる。
【0013】
上記、折り目付け作業を行った後、上蓋天板(60)は後面外板(50)から横折線(51a)を主体として折り曲げられ、次いで上蓋前面板(70)も直角に折り曲げ、先端の上蓋前面板補強板(76)はその内側を接着糊付けされ、折り返されて上蓋前面板(70)に接着される。また、接着糊付けされた上蓋前面接着片(74R、74L)も直角に折り曲げられた後、上蓋側面板(64R、64L)の内側に接着され、前面と左右側面を持つ上蓋部(100)が形成される。なお、この状態では流通時に必要とされる密閉状態でないため、前記上蓋側面板(64R、64L)の内、上蓋側面板切り離しミシン目(63)で区切られる略3角形状の側面板補強板(66R、66L)の裏側に接着糊付けをし上蓋部(100)を箱本体部に覆い重ねて接着すると共に、前記折り曲げて形成させた上蓋前面板補強板(76)上にもスポット状に接着糊付けをして上蓋が開かないように仮付けしておく。
この状態、もしくはシュリンク状の樹脂フィルムで全面を包装した状態で消費者の元に流通する。
【0014】
消費者においては、使用開始に当たり、まず仮止めされてあるカートンの上蓋前面部を持ち上方に引き上げることで、上蓋部(100)を構成する上蓋側面板(64R、64L)の内、上蓋側面板切り離しミシン目(63)を境目としてカートン胴体側面部と接着している側面板補強板(66R、66L)を切り離して、上蓋部として上方に開き、開口部が露出する。
【0015】
実施例1の上蓋カートンでは、上蓋部(100)が上蓋前面板(70)、左右の上蓋側面板(64R、64L)、上蓋天板(60)からなる立体的な上蓋部であり、また後面外板(50)との連接部で上蓋部の回転支軸となる所には横折線(51a)及び同軸上に2つのヒンジ部(53)を持つ構成となっている。前記ヒンジ部(53)は図1(c)に示すようにヒンジ部縦切込み(53v)と横折線上から数mm上蓋天板寄りに偏って設けられたヒンジ部横折線(53h)からなる略H字状の形状のヒンジであるため、横折線(51a)を回転支軸として動く上蓋部の開閉動作に対し、ヒンジ部下方部分が突っ張り、障害となり止めようとする効果が発生するため、上蓋部が直角から更に約120度〜140度程後方に開いた状態においては、立体形状の上蓋部の重量的バランスと、前記折線上のヒンジ部の係止的動きにより、上蓋部(100)は手を離しても開いた状態を維持し、内容物を取り出す際に上蓋部を手で抑えておく必要がない。
【0016】
なお、本実施例でのヒンジ形状としては3本の直線からなる略H字状のものについて説明したが、縦方向切込みは円弧状切込みでも><字状切込みでも良く、またこの間を結ぶ横方向折線も円弧状やV字状の折線でも良く、その組み合わせが前記した突っ張り効果を生じるヒンジ形状であれば良く、また回転軸である横折線(51a)上に3個以上のヒンジ部を設けても構わない。
【0017】
従って、開口部より覗いているキッチンペーパー、ティッシュペーパー、ビニル袋等、折り重ねられた枚葉シートや袋などの内容物を片手のみで引き出し、使用に供することができる。また、内容物がZ字状に折り畳まれて収納されていれば、1枚取り出すと、折り重ねられている次葉の枚葉シートの一部が半立ち状態で開口部に位置するので、続けて使用するのにも便利である。
【0018】
また、使用が終わり上蓋部を閉じる場合は、ヒンジ部の突っ張り以上の力を加えて閉じ、図1(b)に示すように上蓋部(100)の上蓋天板(60)は天板(20)上に、上蓋前面板(70)は前面板(30)上に重なる閉じた状態になる。
【0019】
但し、このままでは上蓋部がロックされないので、ロックするためには前面板(30)の開口部端に連接して設けられている上蓋部係止片(32)を上蓋部係止片補助切り込み(33)を持つ横折線(33a)に従い少し外方に折り曲げておき、上蓋部(100)内の上蓋前面板(70)の先端部内側に折り曲げて設けてある上蓋前面板補強板(76)に引っかけ、ロックさせる。再度、上蓋部(100)を開ける際にはそのまま上に一定以上の力で引き上げれば引っかかっている上蓋部係止片(32)は反り戻り、ロックははずれ、簡単な構成でリクローズ性を備えたロック機構が実現できる。
【0020】
参考
また本発明に係る上蓋カートンの一参考例として、上蓋開き自立状態における見取り図を図3(a)に、側面断面図を図3(b)に、上蓋部回転支軸となる横折線部の逆U字状切込み突起部の拡大図を図3(c)に示し、その上蓋カートンを1枚のブランクに展開した展開図を図4に示す。
【0021】
参考例の上蓋カートンは図4に示すように、直方体の胴部を構成する後面板(10),天板(20)、前面板(30)、底面板(40)、後面外板(50)とその左右側面部を構成する側面板(24R、24L)、及び上蓋部を構成する長上蓋天板(62b)、短上蓋天板(62a)、上蓋前面板(70)の部材と組立時に相互の部材を接着させるための幾つかの接着片などを持ち、実線で図示される外形線、及び切込み線で型紙より打ち抜き機にて用意される。またこの打ち抜きの際に天板(20)と前面板(30)に跨る中央部には周縁部を残して内容物を取り出す開口部が同時に打ち抜かれ形成される。
【0022】
参考例では、上蓋天板(60)は、上蓋天板ミシン目(61)にて区切られる長上蓋天板(62b)、短上蓋天板(62a)より構成されており、また上蓋部の回転支軸となる横折線(51a)上の中央部には図3(c)に示すような突起補助切り込み(55a)を左右両端に持つ逆U字状切込み突起(55)の切込みが前記打ち抜き工程時に形成されている。後述するカートン組立により前記逆U字状切込み突起部と上蓋部下端に形成される該U字状切込み突起部相当抜き部分は後述する上蓋部(100)の開閉動作においてはカートンの紙厚により引っかかり開いた上蓋部(100)が戻ろうとする動きに対し係止的効果を生じる。
【0023】
カートンの胴部の組立は前述の実施例1とほぼ同様であり、まずカートン胴部となる部材を横折線に従って折り込んでいき、後面外板(50)と後面板(10)がその上辺にて一致するように接着される。なお、この際、横折線(51a)中央部に設けられた逆U字状切込み突起(55)部には折り目を付けず、折線相当部分から下側部分を接着しておく。また、上蓋前面板(70)のうち上蓋前面板切り離しミシン目(73)で区切られる前面板補強板(72R、72L)部には接着糊付けをし、前面板(30)上に接着して開口部を密封し、左右が閉じられていない筒状直方体が形成され、内容物を充填した後、左右の側面板を接着しカートンの組み立ては完成する。
【0024】
消費者に流通し使用に際しても実施例1の場合と同様に、まずカートンの前面部にある挿し込み板(72M)を引き上げ、接着密封してある上蓋前面板(70)を上蓋前面板切り離しミシン目(73)部から上を切り離し、上蓋部(100)を開放する。次に上蓋天板(60)内に設けられている上蓋天板ミシン目(61)にて軽く、逆く字状に折り曲げる。上蓋部(100)を開くに当たっては、回転支軸となる横折線(51a)の中央部に設けられた逆U字状切込み突起(55)を乗り越えて後方に回転させ開く。この後方に大きく上蓋部(100)を開いた状態では、図3(b)に示すように横から見て立体状になった上蓋部(100)の重量的バランスと、回転軸上に設けられた逆U字状切込み突起(55)の戻ろうとする動きに対する係止効果により、上蓋部(100)はほぼ直立した状態で自立するため、消費者は内容物を上蓋部を戻らないよう押し留めながら取り出すことなく簡単に片手で取り出せる。
【0025】
また、上蓋部(100)を閉じる時は開く時と同様に逆U字状切込み突起を乗り越えるのに十分な適当な力により閉じれば、開口部を覆う使用前の閉じた状態に戻すことができ、上蓋をロックするには上蓋前面板(70)の先端に連接して設けられている挿し込み片把持板(72M)を折線に従い少し上方に反らしてその折線中心部に設けられている挿し込み片(71)を前面板(30)内の挿し込み片係止部(31)に挿し込みロックさせ、内容物を水滴飛びや油跳ねなど想定される台所などの使用環境下から保護することができる。なお、本実施例では逆U字状切込み突起(55)は横折線(51a)上に1つ設けたもので説明したが、適宜長さをもつ複数個の逆U字状切込み突起を持つものでも同様であり、またその形状も逆U字状以外に意匠性を考えて長円状や楕円状など舌片として同様に係止効果が得られれば適宜形状で構わない。
【0026】
【発明の効果】
以上のように本発明の請求項1及び2に発明の上蓋カートンでは、上蓋部の回転支軸となる横折線部に2本1組の縦方向切れ込みとこの間を前記横折線より上蓋寄りにずらして設けた横方向折線によって形成される略H字形状のヒンジ部を持ち、該ヒンジ部が上蓋部の開閉動作に対し、障害となり係止する効果を持つため、上蓋部が立体的形状であり開いた状態の際に重量的バランスをある角度にて取りやすいことと相まって上蓋部が開いた状態を維持することが可能であり、開口部から折り畳んで収納されているシート状内容物を上蓋部を片手で抑えることなく簡便に取り出すことができる。また上蓋部が開いて自立した状態から、軽く手前に引く動作で上蓋部は閉じることが可能であり、閉じた状態では上蓋部係止部により上蓋部はロックされ、開口部は上蓋部により完全に覆うことができるので、台所など水滴飛びや油跳ねなどから内容物を保護することが可能であり、必要時には挿し込み把持片を片手で掴んで開ける簡便に開けることが可能な使い勝手のよい上蓋カートンを簡単な構成と組み立てで提供できる。更に、上蓋部が上蓋側面部と上蓋前面部を持つ立体的形状になっているためより上蓋部の開け閉めが意図した通りスムーズに行えるとともに高級感も演出でき他類似商品との差別化も図ることができ、また箱としての剛性も上がるなどの効果がある。
【0027】
また、本発明の参考例の上蓋カートンでは、上蓋部の回転支軸となる横折線部に逆U字形状などの舌片状切込み突起部を持ち、該舌片状切込み突起部が上蓋部の開閉動作に対し、障害となり係止する効果を持つため、上蓋部が開いた状態では天板部が逆く字状となり立体的形状のため重量的バランスをある角度にて取りやすいことと相まって上蓋部がほぼ直立した状態で開いた状態を維持することが可能であるため、開口部から折り畳んで収納されているシート状内容物を上蓋部を片手で抑えることなく簡便に取り出すことができる。また上蓋部が開いた自立状態からの閉じる動作も軽い力で行え、ロックできる効果は前記請求項1、2のカートンと同様にある。

Then, the adhesive is further glued on the side plate (44R) to adhere to the side plate (24R). With this one side closed, a predetermined amount of sheet-like contents folded in advance are filled from the side, and then the other side is folded and bonded in the same manner to assemble the carton box body. Is completed.
[0012]
Next, when assembling the upper lid portion (100), the upper lid top plate (60) is parallel to the horizontal folding line (51a) which is the boundary between the rear outer plate (50) and the upper lid top plate (60). A crease is made in advance using a muscle pusher or the like so that the hinge side folding line (53h) provided by shifting toward the side does not mistakenly be on the same straight line. By providing the horizontal fold line (53h) of the hinge part with a slight shift from the horizontal fold line (51a) serving as the rotation support shaft of the upper lid part, when the upper lid part is opened and closed, the upper lid part is opened. It becomes a pawl against the movement of the part to return, and the locking effect of the hinge part is produced.
[0013]
After performing the above-described crease operation, the top lid top plate (60) is folded from the rear outer plate (50) with the horizontal folding line (51a) as a main body, and then the upper lid front plate (70) is also bent at a right angle, and the top lid of the tip The front plate reinforcing plate (76) is adhesively glued on the inside, folded back and bonded to the upper lid front plate (70). Also, the adhesive lid glued upper lid front adhesive pieces (74R, 74L) are bent at right angles and then adhered to the inner side of the upper lid side plates (64R, 64L) to form the upper lid portion (100) having the front and left and right sides. Is done. In this state, since it is not a sealed state required at the time of distribution, among the upper lid side plates (64R, 64L), a substantially triangular side plate reinforcing plate (separated by an upper lid side plate separation perforation (63)) ( 66R, 66L), and the upper lid portion (100) is covered and adhered to the box body, and the upper lid front plate reinforcing plate (76) formed by bending is also glued in a spot shape. And temporarily attach it so that the upper lid does not open.
In this state, or in a state where the entire surface is packaged with a shrink-like resin film, it is distributed to consumers.
[0014]
At the start of use, the consumer first holds the front surface portion of the upper lid of the carton that is temporarily fixed and pulls it upward, so that the upper lid side plate (64R, 64L) that forms the upper lid portion (100) is the upper lid side plate. The side plate reinforcing plates (66R, 66L) bonded to the carton body side surface portion are separated with the separation perforation (63) as a boundary, and are opened upward as the upper lid portion to expose the opening.
[0015]
In the upper lid carton of Example 1, the upper lid portion (100) is a three-dimensional upper lid portion comprising an upper lid front plate (70), left and right upper lid side plates (64R, 64L), and an upper lid top plate (60). At the place where it is connected to the outer plate (50), which is the rotation support shaft of the upper lid, there is a horizontal folding line (51a) and two hinges (53) on the same axis. As shown in FIG. 1 (c), the hinge part (53) is substantially composed of a hinge part vertical cut (53v) and a hinge part horizontal fold line (53h) provided so as to be offset from the horizontal fold line by several mm toward the top lid top plate. Since it is an H-shaped hinge, the lower part of the hinge part is stretched against the opening / closing operation of the upper cover part that moves with the horizontal folding line (51a) as the rotation support shaft, and the effect of trying to stop it becomes an obstacle. In a state where the portion is further opened from about 120 degrees to 140 degrees from a right angle, the upper lid portion (100) is caused by the weight balance of the three-dimensional upper lid portion and the latching movement of the hinge portion on the fold line. Even if the hand is released, it remains open and there is no need to hold the upper lid by hand when taking out the contents.
[0016]
The hinge shape in this embodiment has been described as being substantially H-shaped consisting of three straight lines. However, the longitudinal cut may be an arc-shaped cut or a <cut-shaped cut, and a horizontal direction connecting these cuts. The fold line may also be an arc shape or a V-shaped fold line, and the combination may be any hinge shape that produces the above-mentioned tension effect, and three or more hinge portions are provided on the horizontal fold line (51a) that is the rotating shaft. It doesn't matter.
[0017]
Therefore, it is possible to draw out contents such as folded sheet sheets and bags, such as kitchen paper, tissue paper, and vinyl bags, which are viewed from the opening, with one hand and use them. In addition, if the contents are folded and stored in a Z-shape, when one sheet is taken out, a part of the sheet of the next leaf that is folded is located in the opening in a semi-standing state. It is also convenient to use.
[0018]
Further, when the upper lid portion is closed after use, the upper lid top plate (60) of the upper lid portion (100) is attached to the top plate (20) as shown in FIG. ) And the upper lid front plate (70) is in a closed state overlying the front plate (30).
[0019]
However, since the upper lid portion is not locked in this state, in order to lock the upper lid portion locking piece (32) connected to the opening end of the front plate (30), the upper lid portion locking piece auxiliary cut ( 33) is bent slightly outward in accordance with the horizontal folding line (33a) having the upper lid front plate reinforcing plate (76) provided on the inner side of the front end portion of the upper lid front plate (70) in the upper lid portion (100). Hook and lock. When the upper cover part (100) is opened again, if the upper cover part (32) is pulled up as it is with a certain level of force, the upper cover part locking piece (32) is warped back, the lock is released, and it has a simple structure and has recloseability. A lock mechanism can be realized.
[0020]

Also as a reference example of the upper lid cartons according to the present onset bright, the sketch in the upper lid opened self-supporting in FIG. 3 (a), a side cross-sectional view in FIG. 3 (b), the transverse fold line portion comprising an upper lid section rotating shaft An enlarged view of the inverted U-shaped cut protrusion is shown in FIG. 3C, and a developed view of the upper cover carton developed on one blank is shown in FIG.
[0021]
As shown in FIG. 4, the upper cover carton of this reference example has a rear plate (10), a top plate (20), a front plate (30), a bottom plate (40), a rear outer plate (50 ) And the side plates (24R, 24L) constituting the left and right side portions thereof, and the members of the long upper lid top plate (62b), the short upper lid top plate (62a) and the upper lid front plate (70) constituting the upper lid portion during assembly. It has several adhesive pieces for bonding the members to each other, and is prepared by a punching machine from the pattern paper with outlines and cut lines shown as solid lines. Further, at the time of this punching, an opening for taking out the contents while leaving the peripheral edge is simultaneously punched and formed in the central portion straddling the top plate (20) and the front plate (30).
[0022]
In this reference example, the upper lid top plate (60) is composed of a long upper lid top plate (62b) and a short upper lid top plate (62a) separated by an upper lid top plate perforation (61). In the center part on the horizontal folding line (51a) serving as the rotation support shaft, the notch of the inverted U-shaped incision protrusion (55) having auxiliary protrusions (55a) on both the left and right sides as shown in FIG. It is formed during the process. The U-shaped cut protrusion corresponding to the reverse U-shaped cut projection and the lower portion formed at the lower end of the upper lid by carton assembly described later are caught by the paper thickness of the carton in the opening / closing operation of the upper lid (100) described later. The open upper lid part (100) has a locking effect on the movement to return.
[0023]
The assembling of the carton body is substantially the same as that of the first embodiment described above. First, the carton body member is folded according to the horizontal folding line, and the rear outer plate (50) and the rear plate (10) are located at the upper side. Glued to match. At this time, the lower U-shaped cut protrusion (55) provided at the central portion of the horizontal fold line (51a) is not creased and the lower portion is bonded to the fold line equivalent portion. Also, the front plate reinforcing plate (72R, 72L) portion of the upper cover front plate (70) separated by the perforation (73) of the upper cover front plate is bonded and glued on the front plate (30). After the parts are sealed and a cylindrical rectangular parallelepiped that is not closed on both sides is formed and filled with the contents, the left and right side plates are bonded to complete the assembly of the carton.
[0024]
In the same manner as in the first embodiment, the insertion plate (72M) on the front part of the carton is first pulled up, and the upper lid front plate (70) that has been adhesively sealed is separated from the upper lid front plate. The top is cut off from the eyes (73) and the upper lid (100) is opened. Next, the upper lid top plate perforation (61) provided in the upper lid top plate (60) is lightly bent in a reverse shape. When opening the upper cover part (100), the upper cover part (100) is rotated backward by opening over the inverted U-shaped incision protrusion (55) provided at the center of the horizontal folding line (51a) serving as a rotation support shaft. In a state where the upper lid portion (100) is greatly opened to the rear, the weight balance of the upper lid portion (100) which is three-dimensional when viewed from the side as shown in FIG. Due to the locking effect of the inverted U-shaped incision protrusion (55) against the returning movement, the upper lid part (100) is self-supporting in an almost upright state, so the consumer presses the contents so as not to return the upper lid part. You can easily take it out with one hand without taking it out.
[0025]
Moreover, when closing the upper lid part (100), it is possible to return to the closed state before use so as to cover the opening as long as the upper lid part (100) is closed with an appropriate force sufficient to get over the inverted U-shaped cutting protrusion. In order to lock the upper lid, the insertion piece gripping plate (72M) provided to be connected to the tip of the upper lid front plate (70) is slightly warped upward according to the fold line and is inserted at the center of the fold line. The piece (71) can be inserted and locked in the insertion piece locking portion (31) in the front plate (30), and the contents can be protected from the assumed environment of use such as a kitchen such as splashing water or splashing oil. it can. In the present embodiment, one reverse U-shaped cut protrusion (55) is provided on the horizontal folding line (51a). However, the reverse U-shaped cut protrusion (55a) has a plurality of reverse U-shaped cut protrusions having appropriate lengths. However, the shape is the same, and the shape may be an appropriate shape as long as the locking effect is similarly obtained as a tongue piece such as an ellipse or an ellipse in consideration of the design other than the inverted U-shape.

【The invention's effect】
As described above, in the upper lid carton according to the first and second aspects of the present invention, a set of two longitudinal cuts in the horizontal folding line portion serving as the rotation support shaft of the upper lid portion and the interval between them are shifted closer to the upper lid than the horizontal folding line. The upper lid has a three-dimensional shape because it has a substantially H-shaped hinge formed by a lateral folding line provided and has the effect of obstructing and locking the opening / closing operation of the upper lid. It is possible to maintain a state in which the upper lid is opened in combination with being easy to take a weight balance at an angle in the opened state, and the upper lid portion is used to hold the sheet-like contents stored by folding from the opening. Can be easily taken out without being suppressed with one hand. In addition, the upper lid can be closed by a light pulling action from the state where the upper lid is open and self-supporting. In the closed state, the upper lid is locked by the upper lid locking portion, and the opening is completely closed by the upper lid. It is possible to protect the contents from splashing water or splashing oil in the kitchen, etc., and when necessary, the user can insert the gripping piece with one hand and open it easily. The carton can be provided with simple configuration and assembly. Furthermore, the upper lid has a three-dimensional shape with a side surface portion on the upper lid and a front surface portion on the upper lid, so that the upper lid can be opened and closed more smoothly as intended, and a high-class feeling can be produced and differentiated from other similar products. And the rigidity of the box is increased.
[0027]
Further, in the upper lid carton of the reference example of the present invention, the horizontal folding line portion serving as the rotation support shaft of the upper lid portion has a tongue-like cut projection portion such as an inverted U shape, and the tongue-like cut projection portion is the upper lid portion. The top cover is coupled with the fact that the top plate is shaped like an upside down shape when the top cover is open, and the three-dimensional shape makes it easy to take a weight balance at a certain angle. Since it is possible to maintain the open state in a state where the portion is almost upright, the sheet-like contents stored by being folded from the opening can be easily taken out without holding the upper lid portion with one hand. Further, the closing operation from the self-supporting state in which the upper lid portion is opened can be performed with a light force, and the effect of being able to be locked is the same as in the carton of the first and second aspects.
