Description

本発明は、開口時に楽に開けられ中身のこぼれ難い缶蓋に関するものである。 The present invention relates to a can lid that can be easily opened when opened and does not easily spill contents.

従来使用されているステイオンタブ式の缶蓋においては、タブの一端とパネル部との隙間に指先を挿入し、タブの一端を引き上げることによってタブの他端が押し下げられ、パネル部に設けられた開口部切り込みを破断させ開口していた。しかしながら、従来のステイオンタブ式の缶蓋の開口は、タブの一端と缶蓋のパネル部の隙間が狭く、指先がわずかしか挿入できないため指先に力が入りにくく特に力の弱い高齢者、女性、子供には開け辛く、爪を傷めやすかった。また、開栓時力を掛ける方向と開口部が同一の為、内容物が開口部から飛び出し易かった。更にタブと缶の結合部が破断してタブと缶が別々になる恐れがある為タブがゴミとして回収されない事がよくある。
特開平７−１６５２３６号公報 In a conventional steion tab type can lid, a fingertip is inserted into the gap between one end of the tab and the panel portion, and the other end of the tab is pushed down by pulling up the one end of the tab. The opening cut was broken and opened. However, the opening of the conventional Steion tab type can lid has a narrow gap between one end of the tab and the panel portion of the can lid, and only a few fingertips can be inserted. It was difficult for children to open and it was easy to damage nails. In addition, since the opening direction is the same as the direction in which the force is applied at the time of opening the plug, the contents easily protrude from the opening. Further, since the joint between the tab and the can breaks and the tab and the can may be separated, the tab is often not collected as garbage.
JP 7-165236 A

解決しようとする問題点は、従来のステイオンタブが力の弱い人や爪の短い人にとって開け難く、更に開栓時に反動で内容物が飛び出る事が有った。 The problem to be solved is that the conventional steion tab is difficult to open for people with weak power or short nails, and the contents may pop out by reaction when opening.

更に、リベット留めされたタブの固定部が複数回折り曲げられる事により破断し、缶とタブが別々になる事があった。 Furthermore, the fixed part of the tab riveted may be broken by bending a plurality of times, and the can and the tab may be separated.

本発明は、上記の目的を達成する為に天板１の凸状の開栓スコア６と隣接する緩傾斜面３に、回転可能にリベット１５留めされた板状の開栓レバー１６を回転させる事により短辺側端部１９が開口部斜面８に押し当てられ、梃子の原理によって開栓スコア６が開栓スコア初綻部９より破断し、もう一方の開栓スコア直線部１１の未削部１２で折れ曲がり開口する。 In order to achieve the above-mentioned object, the present invention rotates a plate-like opening lever 16 that is rotatably attached to a gently inclined surface 3 adjacent to the convex opening score 6 of the top plate 1 by a rivet 15 . As a result, the end 19 on the short side is pressed against the inclined surface 8 of the opening, and the opening score 6 breaks from the opening opening score initial failure portion 9 by the principle of the lever, and the other opening score straight line portion 11 is not cut. The portion 12 is bent and opened.

本発明は、開栓レバー１６の回転軸となるリベット１５が緩傾斜面３に留められる事によって角度が付けられている為、未開栓時は長辺側端部２０が缶上端よりはみ出す事も無く、開栓時に缶上端より長辺側端部２０がはみ出る為に力を掛け易く、更に缶蓋中心点２から回転軸をずらす事でリベット１５から長辺側端部２０までの距離もより長く取れ、開栓レバー１６をリベット１５で回転させ開口部斜面８に押し当てる事により、梃子の原理にて容易に開栓することが出来。開栓時の缶の動きも水平方向の回転となる為、内容物が飛び出し難い缶蓋を提供する事を目的としている。 In the present invention, since the rivet 15 serving as the rotation shaft of the opening lever 16 is angled by being fastened to the gently inclined surface 3, the long side end 20 may protrude beyond the upper end of the can when not opened. Without opening, the end 20 on the long side protrudes from the upper end of the can, so it is easy to apply force, and the distance from the rivet 15 to the end 20 on the long side is further increased by shifting the rotation axis from the can lid center point 2. It can be opened easily by the lever principle by turning the opening lever 16 with the rivet 15 and pressing it against the inclined surface 8 of the opening. Since the movement of the can at the time of opening is also a horizontal rotation, the object is to provide a can lid in which the contents are difficult to pop out.

開口部７を緩やかな開口部斜面８を持つ凸状に成型する事で、強度を確保しつつ天板１の緩傾斜面３が浅い角度でも開栓を可能にした。 By molding the opening 7 into a convex shape having a gentle opening slope 8, it is possible to open the plug even when the gentle slope 3 of the top plate 1 is shallow, while ensuring strength.

タブに指先を引っ掛ける必要が無い為、爪を傷付ける事もない。また回転軸が斜めになっているので、缶上端から開栓レバー１６がはみ出し指の腹側で力を掛け易くなる。 There is no need to hang your fingertips on the tabs, so your nails will not be damaged. Further, since the rotation shaft is inclined, the opening lever 16 protrudes from the upper end of the can and it is easy to apply a force on the ventral side of the finger.

開栓レバー１６の開栓レバー取り付け用穴１７を扇形長円状開栓レバー取り付け用穴２１にする事で、開栓時に開栓レバー１６をスライドさせ天板１から浮かせ、親指や複数の指を開栓レバー１６に掛けやすくする事が出来るので、より楽に開栓出来る。 By making the opening lever mounting hole 17 of the opening lever 16 into a fan-shaped oval opening lever mounting hole 21, the opening lever 16 is slid to float from the top plate 1 when opening, and a thumb or a plurality of fingers Can be easily hung on the opening lever 16 so that it can be opened more easily.

開栓作業が開栓レバー１６を回転軸で回転させ開口部斜面８に押し当てる方法であり、垂直方向の回転運動ではない為、開栓時に反動で内容物が飛び出る事もない。 The opening operation is a method in which the opening lever 16 is rotated around the rotating shaft and pressed against the inclined surface 8 of the opening, and since it is not a rotational movement in the vertical direction, the contents do not pop out by reaction when opening.

リベット１５による回転軸の為開栓レバー１６が破断して缶と分離する事もない。 Because of the rotation shaft by the rivet 15, the opening lever 16 is not broken and separated from the can.

補強リブ凸１４と開栓スコアの未削部１２を隣接させ段差を作る事で、開栓スコアの未削部１２と開栓レバー１６への皮膚の挟み込みを防止出来る。 By making the reinforcing rib projection 14 and the uncut portion 12 of the opening score adjacent to each other to create a step, it is possible to prevent the skin from being caught between the uncut portion 12 of the opening score and the opening lever 16 .

開栓作業による指の運動方向に開栓スコア６が無い為、切り口で指を怪我する危険が少ない。 Since there is no opening score 6 in the direction of finger movement due to the opening operation, there is little risk of injury to the finger at the cut end.

上記において説明したように本発明は容易に実施可能である。 As described above, the present invention can be easily implemented.

以下、本発明の実施の形態についての一例を説明する。
まず、開栓レバー１６を緩傾斜面３に回転可能な状態且つ開栓レバー１６の短辺側端部１９が開口部斜面８と隣接するようリベット１５にて取り付ける。
その際指掛け用切り欠き１８に突起５がはまり開栓レバー１６の動きはある程度制限される。 Hereinafter, an example of the embodiment of the present invention will be described.
First, the opening lever 16 is attached by the rivet 15 so that the opening lever 16 can rotate on the gently inclined surface 3 and the end 19 on the short side of the opening lever 16 is adjacent to the opening slope 8.
At that time, the protrusion 5 is fitted into the finger notch 18 and the movement of the opening lever 16 is restricted to some extent.

尚、開栓レバー取り付け用穴１７から短辺側端部１９までの距離をＬ、リベット用穴４から未削部１２までの距離をＡとすると、Ｌ＞Ａとする。 If the distance from the opening lever mounting hole 17 to the short side end 19 is L and the distance from the rivet hole 4 to the uncut portion 12 is A, then L> A.

上記構成による天板１に設けられた開口部７が開口するまでの動作を説明すれば、まず、開栓レバー１６が開口部斜面８と隣接する状態を開栓前とし開栓レバー１６の指掛け用切り欠き１８を押し出すようにリベット１５を中心に回転させる。 The operation until the opening 7 provided in the top plate 1 having the above structure is opened will be described. First, the state in which the opening lever 16 is adjacent to the opening inclined surface 8 is the state before opening the finger. Rotate about the rivet 15 to push out the notch 18 for use.

この時、開栓レバー取り付け用穴１７を扇形長円状取り付け用穴２１にする事で、開栓レバー１６が僅かにスライドして長辺側端部２０が天板１よりはみ出る為、より指が掛け易くなる。 At this time, by making the opening lever mounting hole 17 into a fan-shaped oblong mounting hole 21, the opening lever 16 slides slightly and the long side end 20 protrudes from the top plate 1, so that more fingers It becomes easy to apply.

これによって短辺側端部１９が、開口部斜面８に乗り上げる形になり、開栓スコア初綻部９へと圧力が加わり開栓スコア６が破断し開栓できる。 As a result, the short side end portion 19 rides on the opening slope 8 and pressure is applied to the opening score initial failure portion 9 so that the opening score 6 breaks and can be opened.

その際、開栓レバー１６は突起５により短辺側端部１９を緩傾斜面３に押し付ける方向に力が掛かる事で、より強く開口部斜面８に力が伝わる。
At that time, the force is transmitted to the opening slope 8 more strongly by applying force in the direction in which the plug opening lever 16 presses the short side end 19 against the gently inclined surface 3 by the protrusion 5.
