【０００３】
【発明が解決しようとする課題】
▲１▼箱体の外側面に接着してあった係止舌片を剥離するものであり、この剥離痕が箱体の外観を損なう。
【０００４】
▲２▼係止舌片を剥離することにより、箱体と係止舌片の強度低下を招く。
▲３▼起こされた係止舌片は、起こされる前に接着されていた箱体の外側面側への復元習性を備え、これが蓋の係止凹部から外れる係止解除習性として作用し、蓋のロックの確実性を損ない、洗剤の吸湿を招き易くなる。
【０００５】
▲４▼蓋に設けてある粘着シール片を剥離するとき、粘着シール片の表層部が箱体の側壁の側に残留して該粘着シール片が層間剥離し、この層間剥離が蓋の広い範囲にまで及んで蓋の強度低下を招く。
【０００６】
本発明の課題は、箱体の外観と強度を損なうことなく、蓋のロックの確実性を向上することにある。
【０００８】

【００１０】
【発明の実施の形態】
粉体洗剤用紙容器１０は、図１、図２に示す如く、箱体１１と蓋１２と封緘紙１３とからなる。
【００１１】
箱体１１は、紙だけ、又は紙を主材料としたプラスチックフィルムをラミネートされた素材を折り曲げて組立てたものであり、正面板１１Ａ、背面板１１Ｂ、両側板１１Ｃ、底板１１Ｄを有し、上面に開口１１Ｅを有する。箱体１１は、正面板１１Ａ、背面板１１Ｂ、側板１１Ｃを上側辺で折り返した内側折り返し片１１Ｆを備え、この折り返し片１１Ｆを内折り接着してある（図３、図４、図６）。
【００１２】
蓋１２は、紙だけ、又は紙を主材料としたプラスチックフィルムをラミネートされた素材を折り曲げて組立てたものであり、前板１２Ａ、後板１２Ｂ、両側板１２Ｃ、天板１２Ｄを有する。蓋１２は、箱体１１の背面板１１Ｂに接着されるヒンジ結合部１２Ｅを後板１２Ｂに備え、箱体１１の開口１１Ｅを覆う。
【００１３】
蓋１２は、前板１２Ａの下縁中央部に全切線又は裏半切線２１を介したつまみ片２２を突出させ、つまみ片２２の裏面を箱体１１の正面板１１Ａの外面の凸部２３に貼り付け、箱体１１の開口１１Ｅを封止する（図３）。凸部２３は、箱体１１の正面板１１Ａの外面に突出るように設けた。尚、蓋１２の前板１２Ａにおいてつまみ片２２を区画する全切線又は裏半切線２１のうち、全切線はつまみ片２２の全巾の両端部を除く範囲に、裏半切線はつまみ片２２の全巾に渡って設けることができる。また、凸部２３はつまみ片２２の内側に隠れる範囲に設けられ、つまみ片２２は凸部２３の高さ方向の中間より上半部に接着され、下半部は接着されなくても良い。つまみ片２２は、凸部２３に貼り付けられて箱体１１の正面板１１Ａの外面から凸部２３の高さだけ浮き上がり、つまみ易い。
【００１４】
箱体１１は、正面板１１Ａにおいて前述の折り返し片１１Ｆに重なる該正面板１１Ａの上側辺の近傍に穿たれた孔３１により、蓋１２を箱体１１にロックするための係合端３１Ａを形成する。また、箱体１１は、折り返し片１１Ｆと正面板１１Ａとの間に間隙を形成するための凸部３２を、折り返し片１１Ｆ（又は正面板１１Ａ）に設け、係合端３１Ａを形成する孔３１の深さを大きくしている（図４）。
【００１５】
蓋１２は、箱体１１に蓋１２をロックするための係合片３３を前述のつまみ片２２により構成する。蓋１２を箱体１１に被せるにあたり、図４に示す如く、つまみ片２２を全切線又は裏半切線の折り曲げ部で内側に向けて折り曲げてこれを係合片３３とし、蓋を閉じることでこの係合片３３（つまみ片２２）を上述の孔３１の係合端３１Ａに係合させ、蓋１２がヒンジ結合部１２Ｅの反発力により開き方向へ復帰するのを防止する。
【００１６】
箱体１１に蓋１２をロックするための前述の係合端３１Ａは、孔３１によらず、正面板１１Ａの上側辺で折り返される折り返し片を箱体１１の外側に折り返し、この外側折り返し片の先端により係合端３１Ａを形成しても良い。
【００１７】

(a)蓋１２をロックするための係合端３１Ａと係合片３３について、係合端３１Ａは箱体１１の側壁（正面板１１Ａ）の外面に予め設け、係合片３３は蓋１２の側面（前板１２Ａ）に予め突出して設けられる。従って、係合端３１Ａを係合片３３の使用に際し、紙容器１０の外観を損なうことがないし、箱体１１と蓋１２の強度低下を招くこともない。
【００１９】
(b)係合片３３は蓋１２の内側に折り曲げられて用いられるが、折り曲げられる前の外方へと広がる復元習性を備え、これが箱体１１の係合端３１Ａに深く当たる係合促進習性として作用し、蓋１２のロックの確実性を向上し、洗剤を吸湿防止する。
【００２０】
(c)箱体１１の側壁（正面板１１Ａ）で折り返し片１１Ｆに重なる上側辺の近傍に穿たれた孔３１、又は折り返し片の先端により係合端３１Ａを形成するから、箱体１１の側壁（正面板１１Ａ）の外面に予め確実に係合端３１Ａを設けることができる。
【００２１】
(d)折り返し片１１Ｆと箱体１１の側壁（正面板１１Ａ）との間に間隙を形成するための凸部３２を箱体１１の側壁（正面板１１Ａ）（折り返し片１１Ｆでも可）にも設けた。従って、上述(c)の孔３１の深さ、折り返し片の先端が箱体１１の側壁に対する段差量を大きくとることができ、蓋１２の係合片３３が閉蓋時にそれらの孔３１又は折り返し片の先端からなる係合端３１Ａに落ち込む節度感を大きくするし、蓋１２のロックの確実性も向上する。
【００２２】
(e)箱体１１の側壁（正面板１１Ａ）の外面に貼り付けられる蓋１２のつまみ片２２が、蓋１２の側面に全切線又は裏半切線２１を介して突出状に設けられる。従って、蓋１２の開蓋時に、つまみ片２２を剥離するとき、つまみ片２２の表層部が箱体１１の側壁（正面板１１Ａ）の側に残留して該つまみ片２２が層間剥離しても、この層間剥離は全切線又は裏半切線２１で止められ、蓋１２の広い範囲に及ぶことを防止でき、蓋１２の強度を損なうことがない。
【００２３】
(f)つまみ片２２を箱体１１の側壁（正面板１１Ａ）の外面に設けた凸部２３に貼り付けたから、つまみ片２２が箱体１１の側壁の外面から浮き上がるように設けられるものとなり、蓋１２の開封時につまみ易くなる。
【００２４】
(g)蓋１２のつまみ片２２を、前述の蓋１２をロックするための係合片３３として兼用でき、紙容器１０を簡素化できる。
【００２５】
尚、紙容器１０にあっては、蓋１２の後板１２Ｂにおいて、図２に示す如く、ヒンジ結合部１２Ｅを挟む両側部を閉蓋状態下でヒンジ結合部１２Ｅの側に延長した舌片部４１としている。蓋１２の開蓋時に、後板１２Ｂが箱体１１の背面板１１Ｂとヒンジ結合部１２Ｅに対し全閉状態から90度を越えて回転すると、後板１２Ｂの両側の舌片部４１が箱体１１の背面板１１Ｂに接する面を表裏反転するに至り（図６）、蓋１２の開き状態を維持する（図５）。
【００２６】
また、箱体１１は両側板１１Ｃに吊手のための金属鋲５１を孔状取着部にリベット止めしているが、金属鋲５１の分別廃棄のために以下の構成を備える。箱体１１は、図５に示す如く、金属鋲５１の取着部の直上の外縁部（側板１１Ｃと折り返し片１１Ｆ）に切断開始部５２を設け、切断開始部５２から金属鋲５１の取着部に至る半切線等の切断誘導線５３を設けている。箱体１１の側板１１Ｃと折り返し片１１Ｆを切断開始部５２から切断誘導線５３に沿って金属鋲５１の取着部まで切断し、金属鋲５１を取外しできる。
【００２７】
また、箱体１１は両側板１１Ｃと背面板１１Ｂに、図２、図５に示す如くの折畳み用罫線６１を備え、使用済の空箱を容易に平たく折畳み可能としている。
【００２８】
【発明の効果】
以上のように本発明によれば、箱体の外観と強度を損なうことなく、蓋のロックの確実性を向上することができる。
