Description

本発明は、容器の口部を封止する天井壁を有するベースと、このベースの天井壁にて破断予定ラインにより区画され注出口を形作る障壁と、この障壁に繋がりその引き起こしにより前記破断予定ラインに沿って前記障壁を引きちぎって注出口を形成するプルトップ式中栓及び、それを備えるキャップに関するものである。   The present invention includes a base having a ceiling wall that seals the mouth of a container, a barrier that is partitioned by a line to be broken at the ceiling wall of the base to form a spout, and the line to be broken by connecting to the barrier and causing it. And a cap provided with the same.

こうした中栓等は一般的に、醤油や食用油などを内容物とする容器に用いられるが、例えば、内容物を高温充填する容器において、容器内が減圧した状態でベースから障壁を一気に引きちぎって抜栓すると、容器が復元する反動で内容物が一緒に飛び散るといった不都合が生じる。このため、従来は、破断予定ラインを細溝で形成し、この細溝で区画した障壁の一端を均等な幅の狭幅部分とすると共に、この狭幅部分を形作る細溝の溝底を厚くすることにより、この肉厚部分にて、密閉壁の引きちぎりを一旦停止させて、抜栓に伴う内容物の飛散を防止していた(例えば、特許文献１参照。)。
実公昭５９−２２０３８号公報 Such plugs are generally used in containers that contain soy sauce or edible oil. For example, in a container that is filled with contents at a high temperature, the container is evacuated and the barrier is removed from the base at once. Unplugging causes the inconvenience that the contents are scattered together by the reaction of restoring the container. For this reason, conventionally, the line to be broken is formed by a narrow groove, and one end of the barrier defined by the narrow groove is made a narrow portion having a uniform width, and the groove bottom of the narrow groove forming the narrow portion is thickened. By doing this, the tearing of the sealing wall was temporarily stopped at this thick portion, and the scattering of the contents accompanying the plugging was prevented (for example, see Patent Document 1).
Japanese Utility Model Publication No.59-22038

しかしながら、上述のキャップは、その細溝がほぼ直線形になる部分の途中に肉厚部分があるため、例えば、密閉壁とベースとの連結が強固で密閉壁を比較的大きな力で引っ張らなければならない場合などでは、勢いあまってそのまま肉厚部分を越えて障壁が一気に引きちぎれて内容物が飛び散ってしまうといった問題があった。   However, since the cap has a thick portion in the middle of the portion where the narrow groove is almost linear, for example, the connection between the sealing wall and the base is strong and the sealing wall must be pulled with a relatively large force. In the case where it was not possible, there was a problem that the contents splattered because of the momentum and the barrier was torn over the thick part as it was.

解決しようとする問題点は、従来技術にあってもなお、比較的大きな力で障壁を引っ張った場合に障壁が一気に引きちぎれてしまうことである。   The problem to be solved is that even in the prior art, when the barrier is pulled with a relatively large force, the barrier is torn off at once.

本発明は、容器の口部を封止する天井壁を有するベースと、このベースの天井壁にて破断予定ラインにより区画され注出口を形作る障壁と、この障壁に繋がりその引き起こしにより前記破断予定ラインに沿って前記障壁を引きちぎって注出口を形成するプルタブとを備えるプルトップ式中栓において、前記破断予定ラインは、円弧形ラインの端部としてなり互いに離間した２つの基点と、前記天井壁の外周縁から近くに位置する２つの頂点と、これら頂点の相互間に介在し前記頂点よりも前記天井壁の外周縁から遠くに位置する折り返し点とをほぼＭ字形に結ぶ破断生起ラインを有し、前記障壁は、前記破断生起ラインにて区画され前記天井壁の外周縁に向かって膨出する２つの膨出部の一方に前記プルタブを備えることを特徴とするプルトップ式中栓である。   The present invention includes a base having a ceiling wall that seals the mouth of a container, a barrier that is partitioned by a line to be broken at the ceiling wall of the base to form a spout, and the line to be broken by connecting to the barrier and causing it. The pull-top type inner stopper includes a pull tab that tears the barrier along the wall to form a spout, and the break planned line is an end of an arc-shaped line and is separated from each other, and the ceiling wall It has a fracture occurrence line that connects two vertices located close to the outer peripheral edge and a folding point that is interposed between these vertices and that is located farther from the outer peripheral edge of the ceiling wall than the vertex. The barrier is provided with the pull tab on one of two bulging portions which are defined by the fracture occurrence line and bulge toward the outer peripheral edge of the ceiling wall. It is a plug in up formula.

また、本発明は、上記中栓にヒンジを介して揺動可能に繋がる蓋体を設けたことを特徴とするプルトップ式中栓を備えるキャップである。   The present invention also provides a cap having a pull-top type inner plug, wherein the inner plug is provided with a lid that is swingably connected via a hinge.

本発明にあっては、プルタブの引き起こしにより、プルタブに隣接する破断生起ラインの頂点からこの頂点に繋がる基点及び折り返し点に向かってそれぞれ障壁の引きちぎりを開始するが、特に、折り返し点での破断は、プルタブに隣接する頂点から折り返し点に向かってのち、プルタブに隣接しない他方の頂点に向かって折り返されて破断に要する力の向きが変わるため、結果として折り返し点では破断しにくくなる。更に、プルタブが存在しない他方の頂点での破断も、折り返し点から当該他方の頂点に向かってのち、この他方の頂点に繋がる基点に向かって折り返されて破断に要する力の向きが再び変わるため、結果としてプルタブが存在しない他方の頂点でも破断しにくくなる。即ち、本発明によれば、破断生起ラインの折り返し点及びプルタブの存在しない他方の頂点で更に大きな破断力が要求されるため、比較的大きな力で障壁を引っ張っても、破断生起ラインの破断はその折り返し点からプルタブの存在しない他方の頂点に至るまでの領域内にて停止し、従来の如く、障壁がベースから一気に引きちぎれてしまうことがない。従って、本発明によれば、使用者には障壁を注意深く引きちぎる等の煩雑さがなく、障壁の引きちぎりを破断生起ラインの折り返し点からプルタブの存在しない他方の頂点に至るまでの領域で確実に一時停止させることにより、抜栓に伴う内容物の飛散を防止することができる。   In the present invention, the pulling of the pull tab starts the tearing of the barrier from the vertex of the fracture occurrence line adjacent to the pull tab toward the base point and the folding point connected to this vertex, in particular, breaking at the folding point. Is turned from the vertex adjacent to the pull tab toward the turning point, and then is turned toward the other vertex not adjacent to the pull tab to change the direction of the force required for breaking. As a result, it is difficult to break at the turning point. Furthermore, since the break at the other apex where the pull tab does not exist is directed from the turn point toward the other apex, it is turned toward the base point connected to the other apex, and the direction of the force required for the break is changed again. As a result, it becomes difficult to break even at the other apex where there is no pull tab. That is, according to the present invention, since a larger breaking force is required at the folding point of the fracture occurrence line and the other apex where the pull tab does not exist, even if the barrier is pulled with a relatively large force, the fracture occurrence line is not broken. It stops in the region from the turning point to the other apex where the pull tab does not exist, and the barrier is not torn off from the base at a stroke as in the prior art. Therefore, according to the present invention, there is no trouble such as carefully tearing the barrier to the user, and the tearing of the barrier is ensured in the region from the turning point of the fracture occurrence line to the other apex where there is no pull tab. By temporarily stopping, it is possible to prevent the contents from being scattered due to the plugging.

また、本発明は、前記中栓にヒンジを介して揺動可能に繋がる蓋体を設けたキャップ、前記中栓に、この中栓に着脱可能に嵌合する蓋体を設けたキャップである。   Further, the present invention is a cap provided with a lid that is swingably connected to the inner plug via a hinge, and a cap provided with a lid that is detachably fitted to the inner plug.

以下、図面を参照して、本発明であるプルトップ式キャップの一形態を詳細に説明にする。   Hereinafter, an embodiment of the pull-top cap according to the present invention will be described in detail with reference to the drawings.

図１(ａ),(ｂ)はそれぞれ、本発明の一形態であるプルトップ式キャップを上方から示す正面図及びそのＸ−Ｘ断面図であり、図２は、図１(ｂ)を矢印Ｖから示す要部背面図である。   1A and 1B are a front view and a cross-sectional view taken along line XX, respectively, showing a pull-top cap according to one embodiment of the present invention, and FIG. It is a principal part rear view shown from.

キャップ１0０は、容器20の口部21に取り付けられる中栓110と、この中栓110にヒンジ120を介して揺動可能に連結される蓋体130とからなる。中栓110は、容器20の口部21にアンダーカット嵌合によって取り付けられるベース111を備える。このベース111は、容器20の口部21を封止する天井壁112を有し、この天井壁112には環状の周壁113が一体に成形されている。この周壁113で包囲された天井壁112には、細溝からなる破断予定ライン１により区画され注出口を形作る障壁114と、この障壁114に繋がりその引き起こしにより破断予定ライン１に沿って障壁114を引きちぎって注出口を形成するプルタブ115とを備える。   The cap 100 includes an inner plug 110 attached to the mouth portion 21 of the container 20, and a lid body 130 that is swingably connected to the inner plug 110 via a hinge 120. The inner plug 110 includes a base 111 attached to the mouth portion 21 of the container 20 by undercut fitting. The base 111 has a ceiling wall 112 that seals the mouth portion 21 of the container 20, and an annular peripheral wall 113 is integrally formed on the ceiling wall 112. On the ceiling wall 112 surrounded by the peripheral wall 113, a barrier 114 is formed that is defined by a planned fracture line 1 made of a narrow groove and forms a spout, and a barrier 114 is formed along the planned fracture line 1 by connecting to the barrier 114 and causing it. And a pull tab 115 that tears to form a spout.

破断予定ライン１は、図２に示す如く、周壁113の中心Ｏ1周りに形成された円弧形のライン２と、この円弧形ライン２の端部である２つの基点Ａ,Ｂに繋がる破断生起ライン３とからなり、この破断生起ライン３は、これら基点Ａ，Ｂと、天井壁112の外周縁（本形態では周壁113の内周縁113e）から近くに位置する２つの頂点Ｃ,Ｄと、これら頂点４,５の相互間に介在し頂点Ｃ,Ｄよりも周壁113の外周縁113eから遠くに位置する折り返し点Ｅとを結んだほぼＭ字形をしている。   As shown in FIG. 2, the planned fracture line 1 is an arc-shaped line 2 formed around the center O 1 of the peripheral wall 113 and two fracture points A and B that are ends of the arc-shaped line 2. The fracture occurrence line 3 includes the base points A and B, and two vertices C and D located near the outer peripheral edge of the ceiling wall 112 (in this embodiment, the inner peripheral edge 113e of the peripheral wall 113). These are generally M-shaped, which are interposed between the vertices 4 and 5 and connect the turning point E located farther from the outer peripheral edge 113e of the peripheral wall 113 than the vertices C and D.

本形態の破断生起ライン３において、基点Ａと頂点Ｃとを結ぶライン3a、基点Ｂと頂点Ｄとを結ぶライン3b、頂点Ｃと折り返し点Ｅを結ぶライン3c及び、頂点Ｄと折り返し点Ｅとを結ぶライン3dはそれぞれほぼ直線で構成され、頂点Ｃ,Ｄ及び折り返し点Ｅにおいてそれぞれ、曲率半径ｒ1,ｒ2をもって曲線的に繋がっている。これにより、障壁114は、破断生起ライン３にて区画された部分に、周壁113の内周縁113eに向かって膨出する２つの膨出部114a,114b（図中斜線に示す。）が形成される。そして、プルタブ115は、これら膨出部114a,114bの一方（本形態では、膨出部114a）に、支柱115aを介してプルリング115bを一体に形成されている。   In the fracture occurrence line 3 of the present embodiment, a line 3a connecting the base point A and the vertex C, a line 3b connecting the base point B and the vertex D, a line 3c connecting the vertex C and the turning point E, and the vertex D and the turning point E Lines 3d connecting each other are substantially straight lines, and are connected in a curved line with radii of curvature r1 and r2 at the vertices C and D and the turning points E, respectively. As a result, the barrier 114 is formed with two bulging portions 114a and 114b (indicated by hatching in the drawing) that bulge toward the inner peripheral edge 113e of the peripheral wall 113 at the portion defined by the fracture occurrence line 3. The In the pull tab 115, a pull ring 115b is integrally formed on one of the bulging portions 114a and 114b (in this embodiment, the bulging portion 114a) via a support column 115a.

本発明にあっては、プルタブ115の引き起こしにより、プルタブ115に隣接する破断生起ライン３の頂点Ｃから基点Ａ及び折り返し点Ｅに向かってそれぞれ障壁114の引きちぎりを開始するが、特に、折り返し点Ｅでの破断は、頂点Ｃから折り返し点Ｅに向かってのち、他方の頂点Ｄに向かって折り返されて破断に要する力の向きが変わるため、結果として折り返し点Ｅでは破断しにくくなる。更に、折り返し点Ｅから頂点Ｄでの破断も、折り返し点Ｅから頂点Ｄに向かってのち、他方の基点Ｂに向かって折り返されて破断に要する力の向きが再び変わるため、結果として頂点Ｄでも破断しにくくなる。即ち、本発明によれば、破断生起ライン３の折り返し点Ｅ及び頂点Ｂで更に大きな破断力が要求されるため、比較的大きな力で障壁114を引っ張っても、破断生起ライン３の破断はその折り返し点Ｅから頂点Ｂに至るまでの領域Ｌ内にて停止し、従来の如く、障壁114がベース110から一気に引きちぎれてしまうことがない。従って、本発明によれば、使用者には障壁114を注意深く引きちぎる等の煩雑さがなく、障壁114の引きちぎりを破断生起ライン３の折り返し点Ｅから頂点Ｂに至るまでの領域Ｌ内で確実に一時停止させることにより、抜栓に伴う内容物の飛散を防止することができる。   In the present invention, the pulling of the pull tab 115 starts the tearing of the barrier 114 from the vertex C of the fracture occurrence line 3 adjacent to the pull tab 115 toward the base point A and the folding point E, respectively. The break at E is directed from the vertex C toward the turn-back point E and then turned toward the other vertex D to change the direction of the force required for breakage. Furthermore, the break from the turn point E to the vertex D is also turned from the turn point E to the vertex D and then turned toward the other base point B, and the direction of the force required for the break is changed again. It becomes difficult to break. That is, according to the present invention, since a larger breaking force is required at the turning points E and apexes B of the fracture occurrence line 3, even if the barrier 114 is pulled with a relatively large force, the fracture of the fracture occurrence line 3 is not It stops in the area | region L from the folding | turning point E to the vertex B, and the barrier 114 is not torn off at a stretch from the base 110 like the past. Therefore, according to the present invention, there is no trouble such as carefully tearing the barrier 114 to the user, and the tearing of the barrier 114 can be surely performed in the region L from the turning point E to the vertex B of the fracture occurrence line 3. By temporarily stopping the content, it is possible to prevent the contents from being scattered due to the unplugging.

図３は、図１,２に示す形態の変形例であって、図１(ｂ)を矢印Ｖから示す要部背面図である。なお、以下の説明において、図１,２と同一部分は同一符号をもって、その説明を省略する。   FIG. 3 is a modification of the embodiment shown in FIGS. 1 and 2 and is a main part rear view showing FIG. In the following description, the same parts as those in FIGS.

本形態において、頂点Ｃと基点Ａとを結ぶライン3aは、頂点Ｃと基点Ａとの相互間に介在しこれらの点Ａ,Ｃよりも周壁113の内周縁113eから遠くに位置する中点Ｆを通る凹み線であり、同様に、頂点Ｄと基点Ｂとを結ぶライン3bも、頂点Ｄと基点Ｂとの相互間に介在しこれらの点Ｂ,Ｄよりも周壁113の内周縁113eから遠くに位置する中点Ｇを通る凹み線である。この場合も、障壁114は、破断生起ライン1bにて区画された部分に、周壁113の内周縁113eに向かって膨出する２つの膨出部114a,114b（図中斜線に示す。）が形成される。そして、プルタブ115も、これら膨出部114a,114bの一方（本形態では、膨出部114a）に、支柱115aを介してプルリング115bを一体に形成されている。   In this embodiment, the line 3a connecting the vertex C and the base point A is interposed between the vertex C and the base point A, and is a midpoint F located farther from the inner peripheral edge 113e of the peripheral wall 113 than these points A and C. Similarly, a line 3b connecting the vertex D and the base point B is also interposed between the vertex D and the base point B, and is farther from the inner peripheral edge 113e of the peripheral wall 113 than these points B and D. It is a dent line which passes through the middle point G located at. Also in this case, the barrier 114 is formed with two bulging portions 114a and 114b (indicated by hatching in the drawing) that bulge toward the inner peripheral edge 113e of the peripheral wall 113 at the portion defined by the fracture occurrence line 1b. Is done. In the pull tab 115, a pull ring 115b is integrally formed on one of the bulging portions 114a and 114b (in this embodiment, the bulging portion 114a) via a support column 115a.

本発明にあっても、プルタブ115の引き起こしにより、プルタブ115に隣接する破断生起ライン３の頂点Ｃから基点Ａ及び折り返し点Ｅに向かってそれぞれ障壁114の引きちぎりを開始するが、特に、折り返し点Ｅでの破断は、頂点Ｃから折り返し点Ｅに向かってのち、他方の頂点Ｄに向かって折り返されて破断に要する力の向きが変わるため、この場合も、折り返し点Ｅでは破断しにくくなる。更に、プルタブ115が存在しない頂点Ｄでの破断でも、折り返し点Ｅから頂点Ｄに向かってのち、この他方の頂点Ｄに繋がる基点Ｂに向かって折り返されて破断に要する力の向きが再び変わるため、この場合も、頂点Ｄでは破断しにくくなる。即ち、本発明によれば、破断生起ライン３の折り返し点Ｅ及び頂点Ｄで更に大きな破断力が要求されるため、比較的大きな力で障壁114を引っ張っても、破断生起ライン３の破断はその折り返し点Ｅから頂点Ｄに至るまでの領域Ｌにて停止し、従来の如く、障壁114がベース110から一気に引きちぎれてしまうことがない。従って、本発明によれば、使用者には障壁114を注意深く引きちぎる等の煩雑さがなく、障壁114の引きちぎりを破断生起ライン３の折り返し点Ｅから頂点Ｄに至るまでの領域Ｌで確実に一時停止させることにより、抜栓に伴う内容物の飛散を防止することができる。   Even in the present invention, the pulling of the pull tab 115 starts the tearing of the barrier 114 from the vertex C of the fracture occurrence line 3 adjacent to the pull tab 115 toward the base point A and the folding point E, respectively. The break at E is directed from the vertex C toward the turn-back point E, and then turned toward the other vertex D to change the direction of the force required for the break. Further, even in a break at the vertex D where the pull tab 115 does not exist, the direction of the force required for the break is changed again by being folded back from the turn point E toward the vertex D and then toward the base point B connected to the other vertex D. Also in this case, it is difficult to break at the vertex D. That is, according to the present invention, since a larger breaking force is required at the turning points E and vertex D of the fracture occurrence line 3, even if the barrier 114 is pulled with a relatively large force, the fracture of the fracture occurrence line 3 is not It stops in the area | region L from the folding | turning point E to the vertex D, and the barrier 114 is not torn off at a stretch from the base 110 like the past. Therefore, according to the present invention, there is no trouble such as carefully tearing the barrier 114 to the user, and the tearing of the barrier 114 is reliably performed in the region L from the turning point E to the vertex D of the fracture occurrence line 3. By temporarily stopping, it is possible to prevent the contents from being scattered due to the plugging.

ところで、本発明の中栓110は、様々な形態のキャップに採用することができる。例えば、蓋体130は、中栓110のベース111に着脱可能に嵌合させてもよい。特に、かかる構成においては、ベース111と蓋体130との嵌合部にそれぞれ、凸部及び凹部を設け、中栓110に対して蓋体130を着脱可能に凹凸嵌合させてもよい。更に、本発明は、ベース111と蓋体130とにそれぞれ、おねじ部及びめねじ部を設け、中栓110に対して蓋体130を着脱可能にねじ止めしてもよい。   By the way, the inner plug 110 of the present invention can be employed in various types of caps. For example, the lid 130 may be detachably fitted to the base 111 of the inner plug 110. In particular, in such a configuration, a convex portion and a concave portion may be provided in the fitting portion between the base 111 and the lid body 130, respectively, and the lid body 130 may be detachably fitted to the inner plug 110. Further, according to the present invention, the base 111 and the lid 130 may be provided with a male screw portion and a female screw portion, respectively, and the lid 130 may be detachably screwed to the inner plug 110.

上述したところは、本発明の好適な実施例を示したに過ぎず、当業者によれば、請求の範囲において、種々の変更を加えることができる。例えば、本発明に係る破断予定ラインは、本形態に示す如く、中心Ｏ1と折り返し点Ｅとを通る軸線Ｘに対して線対称な形状であれば、プルタブ115の引き起こしによる障壁114の引きちぎりを効果的に実現できるが、必ずしも線対称である必要はない。また、頂点Ｃ,Ｄと折り返し点Ｅはそれぞれ、曲率半径ｒ1,ｒ2のほぼＵ字形をなしているが、基点Ａと頂点Ｃとの相互間、頂点Ｃと折り返し点Ｅとの相互間をそれぞれ直線的に繋いで鋭角なＶ字形としてもよい。同様に、基点Ｂと頂点Ｄとの相互間、頂点Ｄと折り返し点Ｅとの相互間も直線的に繋いで鋭角なＶ字形としてもよい。また、内容物の使いきりを想定した場合は、蓋体130を用いることなく、中栓110のみで使用することもできる。   The above description is only a preferred embodiment of the present invention, and various modifications can be made by those skilled in the art within the scope of the claims. For example, if the planned break line according to the present invention has a line-symmetric shape with respect to the axis X passing through the center O1 and the turning point E as shown in the present embodiment, the barrier 114 caused by the pull tab 115 is torn off. Although effective, it does not necessarily have to be line symmetric. The vertices C and D and the turning points E are substantially U-shaped with the radii of curvature r1 and r2, respectively, but between the base point A and the vertex C and between the vertex C and the turning point E, respectively. It is good also as an acute-angled V character shape connected linearly. Similarly, the base point B and the vertex D, and the vertex D and the turning point E may be linearly connected to form an acute V shape. Further, when it is assumed that the contents are used up, the inner plug 110 can be used without using the lid 130.
