Description

【０００１】
【産業上の利用分野】
本発明は液体収納容器の注ぎ口に取り付けられる液体収納容器用プルタブに関するものである。
【０００２】
【従来技術及び発明が解決しようとする課題】
従来、紙又はプラスチックを主たる素材として形成される液体収納容器には注ぎ口が設けられており、該注ぎ口にはフイルム状のシートや樹脂製のプルタブ等の蓋材が取り付けられ密封されている。そしてその開封は、該蓋材全体を剥がし取ることによって行われる。
【０００３】
しかしながら蓋材全体を剥がし取ってしまうと、注ぎ口が常に開放された状態となるので、ジュースなどの内容物がこぼれやすくなってしまう。また剥がし取られた蓋材が液体収納容器とは別のゴミとなってしまい、これを安易に捨てることによってゴミ問題が引き起こされる。
【０００４】
これらの問題点を解決するため、蓋材の一部分のみを剥がすようにすることも可能であるが、この場合、剥がした蓋材から手を離すと、該蓋材自身の復元力（いわゆる「腰」）によって、該蓋材が再び注ぎ口に覆いかぶさってしまうという不具合があった。
【０００５】
また蓋材の一部分のみを剥がすようにした場合は、その注ぎ口に直接口を付けて内容物を飲むときに、剥がして引き上げた状態の蓋材が鼻に当たって邪魔になってしまうという問題点もあった。
【０００６】
本発明は上述の点に鑑みてなされたものでありその目的は、開封後のプルタブが容器に残ったままでも十分な開封状態を保ち注ぎ口を覆わず、且つ飲料時の邪魔にならず、しかも構造が簡単で製造の容易な液体収納容器用プルタブを提供することにある。
【０００７】
【課題を解決するための手段】
上記問題点を解決するため本発明は、紙又はプラスチックを主たる素材として形成された液体収納容器の注ぎ口を覆ってこれを密封するように取り付けられる液体収納容器用プルタブにおいて、前記プルタブは、シート状であってその周囲を連結部を残してリング状にカットすることによってその外側部分を取っ手部、内側部分を本体部として構成し、前記本体部の連結部と反対側の端部を、該端部と連結部を結ぶ線に対して斜めの線で裏面側に折り返し、さらにこのプルタブを注ぎ口の上に載せて前記折り返した部分の下面を前記液体収納容器表面に接着するとともに、該折り返した部分と前記連結部の間の本体部の部分で前記注ぎ口を塞いで密封して構成した。
【０００８】
【作用】
プルタブを開封した際、本体部の折り返した部分が広がった状態をそのまま保持するので、該プルタブが再び注ぎ口を閉じる方向に移動しようとすることはなく（又はその力は小さく）、従って十分な開封状態を容易に維持できる。
また本体部の連結部と反対側の端部は、該端部と連結部を結ぶ線に対して斜めの線で裏面側に折り返されているので、開封したプルタブは横方向を向いて係止される。従って直接注ぎ口に口を付けて内容物を飲む場合であっても、該引き上げて係止したプルタブが鼻に当たって邪魔になることはない。
【０００９】
【実施例】
以下、本発明の１実施例を図面に基づいて詳細に説明する。
図１は本発明の１実施例にかかる液体収納容器用プルタブを示す図であり、同図（ａ）は斜視図、同図（ｂ）は平面図、同図（ｃ）は同図（ｂ）のＡ−Ａ断面拡大図である。
【００１０】
同図に示すようにこのプルタブ１０は、紙又はプラスチックを主たる素材として形成された液体収納容器８０の上蓋８１に設けた注ぎ口８３を覆ってこれを密封するように取り付けられている。
【００１１】
ここでプルタブ１０は、その外形が略楕円状の樹脂製シートで形成されており、その周囲を連結部１５を残してリング状にカットし（カット線１７）、その外側部分を取っ手部２０とし、内側部分を本体部３０としている。
【００１２】
そして本体部３０の連結部１５と反対側の端部は、該端部と連結部１５を結ぶ線（プルタブ１０の長手方向）に対して約４５度斜めの折り曲げ線３３で裏面側に折り返されている。折り返された部分が固定部３１となる（点線で示す）。
【００１３】
言い替えればこの折り曲げ線３３は、この液体収納容器８０の注ぎ口８３に口を付けて内容物を飲むときに該注ぎ口８３を傾ける方向（図１（ｂ）のＡ−Ａ線方向）に対して約４５度斜めの線となるように形成されている。
【００１４】
また折り曲げ線３３の中央には、円弧状に突出する係止片３５が設けられている。
【００１５】
次にこのプルタブ１０の製造と液体収納容器８０への取り付けは以下のようにして行われる。
【００１６】
即ちまず図４に示すように、プルタブ１０の外形をシートから打ち抜く工程と、カット線１７とカット線１９を設ける工程を一度のカット工程によって行う。
【００１７】
次にカット線１９の両端を結ぶ線を折り曲げ線３３（図１参照）として固定部３１を本体部３０の裏面側（図４の矢印方向）に折り曲げる。
【００１８】
次にこのプルタブ１０を図１に示すように液体収納容器８０の上蓋８１の上に載せ、折り返した固定部３１と前記連結部１５の間の本体部３０の部分で前記注ぎ口８３を覆った状態でプルタブ１０の固定部３１の下面を上蓋８１に接着又は溶着して固定する。固定する面を図１（ｂ）の点線の斜線で示す。
【００１９】
一方図１（ｃ）に示すように液体収納容器８０の内面と前記プルタブ１０下面の注ぎ口８３に面する面に、薄い樹脂製フイルム８７を密着して張り付けて注ぎ口８３を封止する。これによってプルタブ１０の取り付けが完了する。
【００２０】
次に図２（ａ）乃至（ｃ）はこのプルタブ１０の開封動作を示す図である。すなわちまず図２（ａ）に示すようにプルタブ１０の取っ手部２０を連結部１５を支点にして引き上げる。
【００２１】
さらに該取っ手部２０を引き上げると、図２（ｂ）に示すように固定部３１の折り曲げ線３３付近を支点として本体部３０が上蓋８１から引き上げられる。このとき本体部３０の下面に張り付けられているフイルム８７（図１（ｃ）参照）が注ぎ口８３の形状に剥ぎ取られ、該注ぎ口８３が開口する。
【００２２】
そしてこの状態でさらに取っ手部２０を持ち上げながら上蓋８１の外周のフランジ８５方向に引っ張ってゆき、図２（ｃ）に示すように該取っ手部２０を上蓋８１のフランジ８５に係止させる。このとき係止片３５の先端は上蓋８１上を回動して固定部３１側に入り込んで上蓋８１上に当接，係止される。
【００２３】
本発明においては、図２（ｃ）に示すようにプルタブ１０を開封した際、本体部３０の折り畳まれた部分が広がった状態をそのまま維持しようとするので、該プルタブ１０が再び注ぎ口８３を閉じる方向に移動しようとすることはなく（又はその力は小さく）、従って十分な開封状態を容易に維持でき、再び注ぎ口８３を覆うことはない。
【００２４】
特にこの実施例の場合、折り曲げ線３３のところに係止片３５を設けたので、上述のようにプルタブ１０を引き上げた際に該係止片３５が固定部３１側に入り込んで上蓋８１上に当接，係止するので、プルタブ１０の十分な開封状態をさらに確実に維持できる。
【００２５】
ところで前述のように本体部３０は折り曲げ線３３付近を支点として引き上げられるが、該折り曲げ線３３は前述のようにプルタブ１０の長手方向に対して約４５度傾いているので、引き上げられた本体部３０は、図２（ｃ）及び図３に示すようにプルタブ１０の当初の長手方向とは約９０度異なる横方向を向いて係止される。
【００２６】
従って直接この注ぎ口８３に口を付けて内容物を飲む場合であっても、該引き上げて係止したプルタブ１０が鼻に当たって邪魔になることはない。
【００２７】
以上本発明の１実施例を詳細に説明したが、本発明はこれに限られるものではない。例えば注ぎ口８３をプルタブ１０によって封止する構造は上記構造に限定されるものではなく、他の種々の封止構造が適用できる。
【００２８】
また折り曲げ線３３の傾斜角度を約４５度以外の角度としても良いことは言うまでもない。
【００２９】
【発明の効果】
以上詳細に説明したように本発明にかかる液体収納容器用プルタブによれば、以下のような優れた効果を有する。
▲１▼開封後のプルタブが液体収納容器に接続されたままの状態でも十分な開封状態を容易に維持でき、再び注ぎ口８３を覆うことはない。
【００３０】
▲２▼プルタブが液体収納容器と別ゴミにならない。
【００３１】
▲３▼プルタブを開封状態として内容物を飲む際、該プルタブは注ぎ口８３の横方向に位置するので、該プルタブが鼻に当たらず邪魔にならない。
【００３２】
▲４▼シートをカットするだけで製造できるので、その製造が容易である。

TECHNICAL FIELD The present invention relates to a liquid storage container pull tab attached to a spout of a liquid storage container.
[0002]
2. Prior Art and Problems to be Solved by the Invention
2. Description of the Related Art Conventionally, a spout is provided in a liquid storage container formed mainly of paper or plastic, and a lid material such as a film-shaped sheet or a resin pull tab is attached to the spout to be sealed. . Then, the opening is performed by peeling off the entire lid material.
[0003]
However, if the entire lid material is peeled off, the spout is always in an open state, so that contents such as juice are easily spilled. Further, the lid material that has been peeled off becomes garbage separate from the liquid storage container. Discarding this easily causes a garbage problem.
[0004]
In order to solve these problems, it is possible to peel off only a part of the lid material. However, in this case, when the hand is released from the peeled lid material, the restoring force of the lid material itself (so-called “low back”) is obtained. ), There is a problem that the lid material again covers the spout.
[0005]
Also, if only a part of the lid material is peeled off, there is also a problem that when the spout is directly attached to the mouth and the contents are drunk, the lid material that has been peeled and pulled up hits the nose and gets in the way. there were.
[0006]
The present invention has been made in view of the above points, the purpose of the present invention is to keep a sufficiently opened state even if the pull tab after opening remains in the container, do not cover the spout, and do not disturb the drink, Moreover, it is an object of the present invention to provide a pull tab for a liquid storage container which has a simple structure and is easy to manufacture.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, the present invention is directed to a liquid storage container pull tab which is attached to cover and seal a spout of a liquid storage container formed mainly of paper or plastic, wherein the pull tab is a sheet By cutting the periphery into a ring shape leaving a connecting part, the outer part is configured as a handle part, the inner part is formed as a main body part, and the end part of the main body part opposite to the connecting part, Fold it back to the back side with a line oblique to the line connecting the end and the connecting part, further put this pull tab on the spout, adhere the lower surface of the folded part to the surface of the liquid storage container, and The spout is sealed by closing the spout at the portion of the main body between the connecting portion and the connecting portion.
[0008]
[Action]
When the pull tab is opened, the folded portion of the main body keeps the spread state, so that the pull tab does not try to move in the direction of closing the spout again (or the force is small), and therefore, it is sufficient. The opened state can be easily maintained.
In addition, the end of the main body opposite to the connecting portion is folded back to the back side with a line oblique to the line connecting the end and the connecting portion, so that the opened pull tab is locked in the lateral direction. Is done. Therefore, even when the contents are drunk with the spout directly attached to the spout, the pulled-up and locked pull tab does not hit the nose and obstruct it.
[0009]
【Example】
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a view showing a pull tab for a liquid storage container according to one embodiment of the present invention. FIG. 1 (a) is a perspective view, FIG. 1 (b) is a plan view, and FIG. 1 (c) is FIG. FIG.
[0010]
As shown in the figure, the pull tab 10 is attached so as to cover a spout 83 provided in an upper lid 81 of a liquid storage container 80 formed mainly of paper or plastic and seal the same.
[0011]
Here, the pull tab 10 is formed of a resin sheet having an approximately elliptical outer shape, and its periphery is cut into a ring shape (cut line 17) except for the connecting portion 15, and its outer portion is used as a handle portion 20. The inner part is a main body 30.
[0012]
Then, the end of the main body 30 opposite to the connecting portion 15 is folded back to the back side at a bending line 33 that is inclined at about 45 degrees with respect to a line connecting the end and the connecting portion 15 (the longitudinal direction of the pull tab 10). ing. The folded part becomes the fixing part 31 (shown by a dotted line).
[0013]
In other words, the bending line 33 is inclined with respect to the direction in which the spout 83 is inclined when the spout 83 of the liquid container 80 is attached to drink the contents (the direction of the line AA in FIG. 1B). It is formed so as to be a line inclined at about 45 degrees.
[0014]
At the center of the bending line 33, a locking piece 35 that protrudes in an arc shape is provided.
[0015]
Next, the production of the pull tab 10 and the attachment to the liquid container 80 are performed as follows.
[0016]
That is, first, as shown in FIG. 4, the step of punching the outer shape of the pull tab 10 from the sheet and the step of providing the cut lines 17 and 19 are performed by a single cutting step.
[0017]
Next, the fixing portion 31 is bent toward the back surface side of the main body 30 (in the direction of the arrow in FIG. 4) as a bending line 33 (see FIG. 1) connecting the both ends of the cut line 19.
[0018]
Next, as shown in FIG. 1, the pull tab 10 was placed on the upper lid 81 of the liquid container 80, and the spout 83 was covered with the folded main part 30 between the fixed part 31 and the connecting part 15. In this state, the lower surface of the fixing portion 31 of the pull tab 10 is fixed to the upper lid 81 by bonding or welding. The surface to be fixed is indicated by the hatched dotted line in FIG.
[0019]
On the other hand, as shown in FIG. 1C, a thin resin film 87 is adhered to the inner surface of the liquid container 80 and the surface of the lower surface of the pull tab 10 facing the spout 83 to seal the spout 83. Thus, the attachment of the pull tab 10 is completed.
[0020]
Next, FIGS. 2A to 2C are views showing the opening operation of the pull tab 10. FIG. That is, first, as shown in FIG. 2A, the handle portion 20 of the pull tab 10 is pulled up with the connecting portion 15 as a fulcrum.
[0021]
When the handle portion 20 is further pulled up, the main body portion 30 is pulled up from the upper lid 81 with the vicinity of the bending line 33 of the fixing portion 31 as a fulcrum as shown in FIG. At this time, the film 87 (see FIG. 1C) attached to the lower surface of the main body 30 is peeled off in the shape of the spout 83, and the spout 83 is opened.
[0022]
In this state, the handle portion 20 is further pulled in the direction of the flange 85 on the outer periphery of the upper cover 81 while being further lifted, and the handle portion 20 is locked to the flange 85 of the upper cover 81 as shown in FIG. At this time, the tip of the locking piece 35 rotates on the upper lid 81, enters the fixing portion 31 side, and abuts and locks on the upper lid 81.
[0023]
In the present invention, as shown in FIG. 2C, when the pull tab 10 is opened, the folded portion of the main body 30 tries to maintain the spread state as it is, so that the pull tab 10 closes the spout 83 again. No attempt is made to move in the closing direction (or the force is small), so that a sufficient open state can be easily maintained and will not cover the spout 83 again.
[0024]
In particular, in the case of this embodiment, since the locking piece 35 is provided at the bending line 33, when the pull tab 10 is pulled up as described above, the locking piece 35 enters the fixing portion 31 side and is placed on the upper lid 81. Since the pull tab 10 is abutted and locked, a sufficient unsealed state of the pull tab 10 can be more reliably maintained.
[0025]
By the way, as described above, the main body portion 30 is pulled up with the vicinity of the bending line 33 as a fulcrum, but since the bending line 33 is inclined about 45 degrees with respect to the longitudinal direction of the pull tab 10 as described above, As shown in FIGS. 2C and 3, the lock 30 is oriented in a lateral direction different from the initial longitudinal direction of the pull tab 10 by about 90 degrees.
[0026]
Therefore, even when the spout 83 is directly attached to the spout to drink the contents, the pulled-up and locked pull tab 10 does not hit the nose and obstruct it.
[0027]
Although one embodiment of the present invention has been described in detail, the present invention is not limited to this. For example, the structure for sealing the spout 83 with the pull tab 10 is not limited to the above structure, and various other sealing structures can be applied.
[0028]
Needless to say, the inclination angle of the bending line 33 may be set to an angle other than about 45 degrees.
[0029]
【The invention's effect】
As described in detail above, the pull tab for a liquid storage container according to the present invention has the following excellent effects.
{Circle around (1)} Even when the pull tab after opening is still connected to the liquid container, a sufficient opening state can be easily maintained, and the spout 83 will not be covered again.
[0030]
(2) The pull tab does not become garbage separate from the liquid storage container.
[0031]
{Circle around (3)} When the contents are to be drunk with the pull tab opened, the pull tab is located in the lateral direction of the spout 83, so that the pull tab does not hit the nose and does not get in the way.
[0032]
{Circle around (4)} Since the sheet can be manufactured only by cutting the sheet, the manufacture is easy.
