Description

本発明は、缶蓋の蓋体パネルがヒンジ部を有してスコア線が形成され、このスコア線に囲まれた舌片状の開口片を押し下げて開口操作を行うプルタブ式の開口缶蓋に関し、プルタブの後端部側の押圧部を親指で下げながら前端部側の指掛け部を人指し指の裏で押し上げながら簡易に舌片状の開口片を開口することが可能な簡易開口缶蓋を提供するものである。  The present invention relates to a pull tab type open can lid in which a lid body panel of a can lid has a hinge portion to form a score line, and an opening operation is performed by pressing down a tongue-shaped opening piece surrounded by the score line. Provided is a simple opening can lid capable of easily opening a tongue-shaped opening piece while pushing a finger-holding portion on the front end side behind the index finger while lowering the pressing portion on the rear end side of the pull tab with a thumb Is.

従来の簡易開口缶蓋は、開口操作を行う薄板状のプルタブを有している。すなわち、蓋体パネルの中央を横断して設けられた凹部のほぼ中央にリベット部を介してプルタブが固着されている。  The conventional simple opening can lid has a thin plate-like pull tab for performing an opening operation. That is, the pull tab is fixed to the substantially center of the recess provided across the center of the lid panel via the rivet portion.

このプルタブには、リベット部に対して互いに反対側に指掛け部と押圧部とが設けられている。蓋体パネルの凹部の押圧側にはスコア線が刻設されるが、このスコア線は開口時にヒンジとなるヒンジ部を残して形成されている。  The pull tab is provided with a finger hook portion and a pressing portion on opposite sides of the rivet portion. A score line is engraved on the pressing side of the concave portion of the lid panel, and this score line is formed leaving a hinge portion that becomes a hinge when opened.

そして、このスコア線に囲まれた部分が、スコア線の破断によって押し下げられる開口片を形成している。一方、指掛け部の近傍下方には、指掛け部に指を掛け易くするために窪み部が蓋体パネルの凹部の上面に設けられている。  And the part enclosed by this score line forms the opening piece pressed down by the fracture | rupture of a score line. On the other hand, a recessed portion is provided on the upper surface of the concave portion of the lid panel so as to make it easier to place a finger on the finger hanging portion below the vicinity of the finger hanging portion.

従来の簡易開口缶蓋を開口するには、指掛け部に指を掛けてプルタブを引き起こすと、リベット部が上方へ引っ張られると共に、押圧部が開口片を下方へ押圧するので、リベット部に近接するスコア線が引きちぎられように初期破断され、さらにプルタブを引き上げることによって、リベット部を支点、押圧部を作用点とするてこ作用により、スコア線に沿って破断が進行し、ヒンジ部をヒンジとして開口片が押し下げられて開口するようになっている。  In order to open the conventional simple can lid, when a finger is placed on the finger-hanging part to cause a pull tab, the rivet part is pulled upward, and the pressing part presses the opening piece downward, so that it is close to the rivet part. The score line is initially broken so that it is torn, and further pulling up the pull tab causes the breakage to progress along the score line by lever action with the rivet part as the fulcrum and the pressing part as the action point, opening the hinge part as a hinge A piece is pushed down to open.

特開２００１−１０６２２８号公報  JP 2001-106228 A

従来の簡易開口間蓋においては、指掛け部と蓋体パネルの上面との隙間が狭く、指を掛けにくいという課題を有し、さらに指を掛け易くするために窪み部及び指掛け分の下面を支持するディンブルが設けられているが強度及び取り扱い上の問題から限界があり、完全は期しがたい。また、薄い板状ノプルタブの下面に指を挿入して引き上げる構造となっているために指を差し込んだ場合に爪を割るという問題があった。  Conventional lids with simple openings have the problem that the gap between the finger rest and the top surface of the lid panel is narrow, making it difficult to place fingers. Dimples are provided, but there are limitations due to strength and handling problems, and it is completely difficult to complete. In addition, since the finger is inserted into the lower surface of the thin plate-like nopple tab and pulled up, there is a problem that the fingernail is broken when the finger is inserted.

また従来のステイオンタブ式の缶蓋は、スコア線の初期破断された部分が空気穴となって缶の内外が錬通され、スコア線の破断が進行される構造であるが、上記の缶蓋は当該気穴となる部分が一箇所なので初期破断後、スコア線が漸次破断されるばあいに比較的大きな力が必要となるものであった。  In addition, the conventional steion tab type can lid has a structure in which the portion where the score line is initially broken serves as an air hole so that the inside and outside of the can are kneaded, and the score line breaks down. Since the lid has only one portion that becomes the pore, a relatively large force is required when the score line is gradually broken after the initial break.

本発明者は、上記課題を解決し、かつ、さらに簡易に開口できる様にするためプルタブ２は後端部側の押掛部８とリベット部３に固定される舌片部１２との接合部を、部分片１３の横幅が舌片部１２の横幅より狭くすると、容易に該押掛部８を下方に押圧させることが出来ることを見出し、さらに親指で該押掛部８を下方に押圧させながらプルタブ前端部側の指掛部９を上方に傾斜させ、次いで人指し指の内側でプルタブ２を引き上げることにより開口し易くすることを見出した。  The present inventor has solved the above-mentioned problems and allows the pull tab 2 to be joined between the pushing portion 8 on the rear end side and the tongue piece portion 12 fixed to the rivet portion 3 so that the opening can be made easier. When the lateral width of the partial piece 13 is narrower than the lateral width of the tongue piece portion 12, it is found that the pushing portion 8 can be easily pushed downward, and the pushing portion 8 is pushed downward with a thumb. However, it has been found that the finger tab 9 on the front end side of the pull tab is inclined upward, and then the pull tab 2 is pulled up inside the index finger to facilitate opening.

本発明は、さらにプルタブ２の両端側に２個の窪み部を設け、開口片側の窪み部５上に位置するプルタブ後端部の押掛部８を押しながら、連動して上方に上がるプルタブ前端部側の指掛部９を上方に傾斜させ、次いで人指し指の内側でプルタブ２を引き上げ易くすると共に、さらに指を上方に引き上げることによって、押掛部８が窪み部５に接しスコア線７が初期破断され、順次開口片が缶内部に押されて開口されるように工夫している。  The present invention further provides two recesses on both ends of the pull tab 2 and pulls the pull tab front end that rises in conjunction with the pushing portion 8 at the rear end of the pull tab located on the recess 5 on the opening piece side. By tilting the finger-holding part 9 on the part side upward and then making it easy to pull up the pull tab 2 inside the index finger, and further lifting the finger upward, the pressing part 8 comes into contact with the hollow part 5 and the score line 7 is initially The device is designed so that it is broken and the opening pieces are sequentially pushed into the can to be opened.

即ち本発明の第一は、蓋体パネル２の上面に、スコア線７に囲まれた舌片状の開口片６を有すると共に、プルタブ２がリベット部３を介してほぼ中央に固着されてなる簡易開口缶蓋において、前記プルタブ２は、後端部側の押掛部８と前記リベット部３に固定される舌片部１２とを連接する部分片１３の横幅が舌片部１２の横幅より狭く連接され、該押掛部８を下方に押圧させながらプルタブ前端部側の指掛部９を上方に傾斜させることを特徴とする簡易開口缶蓋である。  That is, the first of the present invention has a tongue-shaped opening piece 6 surrounded by the score line 7 on the upper surface of the lid panel 2 and the pull tab 2 is fixed to the substantially center through the rivet portion 3. In the simple opening can lid, the pull tab 2 has a lateral width of the partial piece 13 connecting the pushing portion 8 on the rear end side and the tongue piece portion 12 fixed to the rivet portion 3 from the lateral width of the tongue piece portion 12. A simple opening can lid characterized in that the finger hooking portion 9 on the front side of the pull tab is inclined upward while being pressed narrowly and pressing the pressing portion 8 downward.

本発明の第二は、第一発明においてプルタブは、後端部側の押掛部８と前記リベット部３に固定される舌片部１２とを連接する部分片１３の横幅が舌片部１２の横幅より少なくとも６分の５以下であることを特徴とする簡易開口缶蓋である。  In the second aspect of the present invention, in the first aspect of the present invention, the pull tab has a lateral width of the piece 13 connecting the pushing portion 8 on the rear end side and the tongue piece 12 fixed to the rivet portion 3. It is a simple opening can lid characterized by being at least 5/6 or less than the lateral width of.

本発明の第三は、第一発明においてプルタブの押掛部８の底部を、押掛部の先端部側から少なくとも傾斜角５度以上の角度を有することを特徴とする簡易開口缶蓋である。  A third aspect of the present invention is a simple opening can lid characterized in that, in the first invention, the bottom portion of the pulling portion 8 of the pull tab has an angle of at least an inclination angle of 5 degrees or more from the tip end side of the pressing portion. .

本発明の第四は、第一発明においてプルタブは、前端部の指掛部９の先端が上方に山形状に形成されてなることを特徴とする簡易開口缶蓋である。  According to a fourth aspect of the present invention, in the first aspect of the present invention, the pull tab is a simple open can lid characterized in that the front end of the finger hook portion 9 is formed in a mountain shape upward.

本発明はさらに蓋体パネル２の上面に、スコア線７に囲まれた舌片状の開口片６を有すると共に、プルタブ２がリベット部３を介してほぼ中央に固着されてなる簡易開口缶蓋において、前記窪み部はプルタブ３の前端部側と後端部側の二箇所に設けられ、プルタブ後端部側の窪み部５はプルタブ後端部側の押掛部８が開口片側の窪み部５表面に押圧されながらプルタブ前端部側の指掛部９を上方に傾斜させることを特徴とする簡易開口缶蓋である。  The present invention further has a tongue-shaped opening piece 6 surrounded by a score line 7 on the upper surface of the lid panel 2, and a simple opening can lid in which the pull tab 2 is fixed substantially at the center via the rivet portion 3. The recesses are provided at two locations on the front end side and the rear end side of the pull tab 3, and the recesses 5 on the rear end side of the pull tab are the recesses on the pull tab rear end side. 5 A simple opening can lid characterized in that the finger hook portion 9 on the front end side of the pull tab is inclined upward while being pressed against the surface.

本発明によれば、従来は指を入れて引き上げる指掛部と窪み部との間にある隙間が狭く、そのため無理やり指をこじ入れるため爪を痛めるという課題があったが、本発明は、指掛部と窪み部の間の隙間を広くとるため、使用者は指の内側で押さえ上部に引き上げるだけで簡易に開口できるものである。  According to the present invention, conventionally, there is a problem that the gap between the finger hooking portion and the recessed portion that is pulled up by inserting a finger is narrow, so that the finger is forced to pry and the nail is damaged. Since the gap between the hanging portion and the recessed portion is widened, the user can easily open it by simply pulling it up to the top of the press inside the finger.

また、プルタブの押掛部を抑える場合に右手親指で抑える場合には、プルタブの指掛け部は左手の人差し指等の指の内側で押さえるだけでよく、更に、手幅の大きい大人の場合は、右手や左手の親指と人指し指を用いて簡易に開口が出来るものである。  Also, when holding the pull tab with the right thumb, hold the pull tab with the finger of the left index finger, etc., and for adults with a large hand width, It can be easily opened using the thumb and index finger of the left hand.

本発明の第一実施の形態を実施例に基づき、図面を参照して説明する。  A first embodiment of the present invention will be described based on examples with reference to the drawings.

図１は、本発明の簡易開口缶蓋を示す斜視図である。本発明の簡易開口蓋缶は、蓋体パネル１の上面に、スコア線７に囲まれた舌片状の開口片６を有すると共に、プルタブ２がリベット部３を介してほぼ中央に固着されてなる簡易開口缶蓋であるが、本発明の第一の特徴は、前記プルタブ２は、後端部側の押掛部８と前記リベット部３に固定される舌片部１２とを連接する部分片１３の横幅が舌片部１２の横幅より狭く連接され、該押掛部８を下方に押圧させながらプルタブ前端部側の指掛部９を上方に傾斜させることを特徴とする簡易開口缶蓋である。  FIG. 1 is a perspective view showing a simple opening can lid of the present invention. The simple opening lid can of the present invention has a tongue-like opening piece 6 surrounded by a score line 7 on the upper surface of the lid panel 1, and a pull tab 2 is fixed substantially at the center via a rivet portion 3. The first feature of the present invention is that the pull tab 2 is a portion that connects the pushing portion 8 on the rear end side and the tongue piece portion 12 fixed to the rivet portion 3. A simple opening can lid characterized in that the lateral width of the piece 13 is connected to be narrower than the lateral width of the tongue piece 12 and the finger hooking portion 9 on the front end side of the pull tab is inclined upward while pressing the pressing portion 8 downward. It is.

この場合、前記プルタブの接合部は図２や図５に示すように、押掛部８と舌片部１２との間が後端部側の押掛部８と前記リベット部３に固定される舌片部１２とを連接する部分片１３の横幅が舌片部１２の横幅より少なくとも６分の５以下であればよい。これ以上であると従来のプルタブのように舌片部１２と押掛部８とが一体的に接続されて固定状態となり、下方への押圧が難しくなる。  In this case, as shown in FIG. 2 and FIG. 5, the joint portion of the pull tab is fixed between the pushing portion 8 and the tongue piece portion 12 to the pushing portion 8 on the rear end side and the rivet portion 3. The width of the piece 13 connecting the tongue piece 12 may be at least 5/6 or less than the width of the tongue piece 12. If it is more than this, the tongue piece 12 and the hooking portion 8 are integrally connected as in a conventional pull tab and become fixed, making downward pressing difficult.

この横幅の狭さは、図２に示すように部分片１３の一方を狭めることによって舌片部１２の最大横幅より少なくすることで左側に傾きながら押し下げられることを見出している。また図５に示すように、部分片１３の両方を狭めることによって舌片部１２の最大横幅より少なくすることで同様に押掛部８の押し下げが容易に出来るようになる。  It has been found that this narrow width can be pushed down while tilting to the left side by narrowing one of the pieces 13 and making it smaller than the maximum width of the tongue piece 12 as shown in FIG. Further, as shown in FIG. 5, the pressing portion 8 can be easily pushed down similarly by narrowing both the partial pieces 13 so as to be smaller than the maximum lateral width of the tongue piece portion 12.

本発明において、プルタブの押掛部８の底部１１は、押掛部の先端部側から少なくとも傾斜角５度以上の角度を有することを特徴とするが、これは角度を設けることによってリベット部３に固定される舌片部１２を基点に押掛部８を下方に押圧させながらプルタブ前端部側の指掛部９を上方に傾斜させることが可能となることによる。この場合、先端部から斜めに角度を持たせるが、最大角度は先端から５０度以内が好ましい。  In the present invention, the bottom portion 11 of the pushing portion 8 of the pull tab is characterized by having an angle of at least an inclination angle of 5 degrees or more from the tip end side of the pushing portion. This is because the finger hook 9 on the front end side of the pull tab can be tilted upward while pressing the hook 8 downward with the tongue piece 12 fixed to the base. In this case, an angle is given obliquely from the tip, but the maximum angle is preferably within 50 degrees from the tip.

本発明において、前端部の指掛部９の先端が上方に山形状に形成されてなることを特徴とするが、これは上方に傾斜された指掛部９に指先を掛けて更に引き上げる効果を与えるものである。此れは図３及び図４に示すようにプルタブ２の押掛部８を下方に押し下げると押掛部８の下端が開口片６の表面に接すると同時に、リベット部３の働きでシーソのように指掛部９が連動して上方に上がり、窪み部９との間に隙間が大きく広がり、使用者は図４のように指先の内側で抑えながら引き上げることが出来るようになる。  The present invention is characterized in that the front end of the finger hook portion 9 is formed in a mountain shape upward, and this has the effect of further pulling up the finger hook portion 9 inclined upward. To give. As shown in FIGS. 3 and 4, when the pushing portion 8 of the pull tab 2 is pushed downward, the lower end of the pushing portion 8 comes into contact with the surface of the opening piece 6 and at the same time, the rivet portion 3 acts like a seesaw. Then, the finger hooking portion 9 is interlocked and lifts upward, and a gap is greatly widened between the hollow portion 9 and the user can pull up while restraining it inside the fingertip as shown in FIG.

本実施例の特徴は、窪み部として従来のように指掛部側の一箇所のみでなく、図３に示すようにプルタブ２の前端部側と後端部側の二箇所に設けられ、プルタブ後端部側の窪み部５はプルタブ後端部側の押掛部８が開口片６側の窪み部５表面に押圧されながらプルタブ前端部側の指掛部９を上方に傾斜させることを特徴とする簡易開口缶蓋である。  The feature of the present embodiment is that it is provided not only at one place on the finger-hanging portion side as in the prior art as a recessed portion but also at two places on the front end side and the rear end side of the pull tab 2 as shown in FIG. The recess 5 on the rear end side is characterized in that the finger hook 9 on the front end side of the pull tab is inclined upward while the pressing portion 8 on the rear end side of the pull tab is pressed against the surface of the recess 5 on the opening piece 6 side. This is a simple open can lid.

この場合、プルタブ２の前端部に設けられる指掛部９の先端は、上方に山形状に形成されることが好ましいが、此れは図４に示すようにプルタブ２の押掛部８を下方に押し下げると指掛部９が連動して上方に上がり、指掛部９下の蓋体パネル表面との間に隙間が大きく広がり、使用者は指先の内側で抑えながら引き上げることが出来るようになる。  In this case, it is preferable that the tip of the finger hook portion 9 provided at the front end portion of the pull tab 2 is formed in a mountain shape upward. This is because the push portion 8 of the pull tab 2 is moved downward as shown in FIG. When pressed down, the finger hooking portion 9 is interlocked and lifted upward, and a gap is greatly widened between the lid panel surface under the finger hooking portion 9 and the user can pull up while restraining inside the fingertip. .

またプルタブ２の後端部側押掛部８の先端部を山形形状に少なくとも３ｍｍ以上、好ましくは５ｍｍ以上の傾斜を有する事が好ましい、此れによって、押掛部８をスコア線７に囲まれた舌片状の開口片４表面に押し下げることによって、リベット部５を支点にしてプルタブ３の前端部側の指掛部３ｂが上方へ傾斜する構造となっている。  Further, it is preferable that the front end portion of the rear end side pushing portion 8 of the pull tab 2 has a mountain shape and has an inclination of at least 3 mm or more, preferably 5 mm or more, whereby the pushing portion 8 is surrounded by the score line 7. By pushing down on the surface of the tongue-shaped opening piece 4, the finger hook portion 3 b on the front end side of the pull tab 3 is inclined upward with the rivet portion 5 as a fulcrum.

本発明の第一の簡易開口缶蓋は、従来開口時に狭い指掛部３ｂに無理やり指を押し込んで開口していたものを、反対側にある押掛部８をその下部に設けた開口片４に接するまで押掛ることによって、リベット部３を支点として作用させながら反対に位置する指掛部３ｂの先端部を上方に上げる構造となっている。  In the first simple opening can lid of the present invention, an opening piece 4 provided with a pressing portion 8 on the opposite side is provided on the lower side of a conventional finger opening portion that is forcibly pushed into a narrow finger holding portion 3b at the time of opening. In this structure, the tip end portion of the finger hook portion 3b positioned opposite to the rivet portion 3 is lifted upward while acting as a fulcrum.

本発明の第二の簡易開口缶蓋は、従来開口時に狭い指掛部９に無理やり指を押し込んで開口していたものを、反対側に設けられている押掛部８をその下部に設けた窪み部５に接するまで押掛ることによって、リベット部３を支点として作用させながら反対に位置する指掛部９の先端部を上方に上げる構造となっている。  The second simple opening can lid of the present invention is provided with a pressing portion 8 provided on the opposite side, which has been opened by forcibly pushing a finger into the narrow finger hanging portion 9 at the time of opening. By pushing until it comes into contact with the indentation portion 5, the tip portion of the finger hook portion 9 positioned in the opposite direction is raised upward while acting as the rivet portion 3 as a fulcrum.

本発明の第二実施例において窪み部５及び窪み部１０の窪み部分は蓋体パネルの２の平面から、窪み部８は２ｍｍ、窪み部９は４ｍｍ下げる状態としたが、此れは隙間をどの程度設けるかによって当然に変わるものである。  In the second embodiment of the present invention, the recessed portions 5 and 10 are lowered from the 2 planes of the lid panel, the recessed portion 8 is lowered by 2 mm, and the recessed portion 9 is lowered by 4 mm. Naturally, it depends on how much it is provided.

本発明で重要なことは、従来のようにリベット部３でプルタブ２を固定しすぎないことであり、プルタブ２がシーソーのようにリベット部３を支点として働くように設定する必要がある。  What is important in the present invention is that the pull tab 2 is not excessively fixed by the rivet portion 3 as in the prior art, and it is necessary to set the pull tab 2 so that the rivet portion 3 works as a fulcrum like a seesaw.

本発明で重要なことは、プルタブ２の後端部側押掛部８を山形形状に少なくとも３ｍｍ以上、好ましくは５ｍｍ以上の傾斜を有する事が好ましい。  What is important in the present invention is that the rear end side pushing portion 8 of the pull tab 2 has an angled shape of at least 3 mm or more, preferably 5 mm or more.
