【発明の実施の形態】
以下、本発明に係る袋用注出栓の実施形態を図面を参照しながら説明する。
図１乃至図４は請求項１、４及び５記載の袋用注出栓を示す。
１は口頸部部材で、口頸筒２の下端部外面から口頸筒２下半部を囲成させて下方小径のテーパ筒３を起立し、該テーパ筒上端部の左右両部から弾性片４を介して下向き半割筒５を左右方向へ突設し、かつこれら左右両半割筒５の前後両側から挟持板６ａ、６ｂを前後方向へ突設する。
なお、半割筒５として、テーパ筒３のテーパとほぼ等しいテーパを有する半割テーパ筒を使用する。
【００１６】
そして、図示例のように、左側に位置する挟持板６ａの中央部に透孔７を穿設すると共に、右側に位置する挟持板６ｂの中央部下面に突起８を形成する。しかし、これに限らず、透孔７を右側に位置する挟持板６ｂに、また突起８を左側に位置する挟持板６ａに、それぞれ形成してもよい。突起８は図示するように、その下部を半球面形状に形成する。
なお、請求項４に記載し、かつ図３に示すように、口頸筒２上面をキャップ９で閉塞させることも可能である。
さらに、請求項５に記載し、かつ図１に示すように、左右の挟持板６ａ、６ｂ下面を互いに噛合い可能な波形の凹凸面１０に形成することもできる。
【００１７】
上記構成に係る口頸部部材１を袋１１に装着するには、図２に示すように、袋１１の上縁と側縁との角部を切除して開口部１２を形成した後、該開口部へテーパ筒３を挿通させる。次いで左右の弾性片４を下方へ屈曲して左右両半割筒５を、袋角部を介してテーパ筒３外面へ嵌合させると共に、左右両挟持板６ａ、６ｂで開口部１２に連続する袋の上縁部分１１ａと側縁部分１１ｂとを挟持させることにより、前後両突起８を袋の上縁部分１１ａと側縁部分１１ｂとを介して透孔７へ挿通させて、半球形状部の端面を透孔７の外縁へ係合させる。
【００１８】
図５乃至図１１は請求項２、４及び５記載の袋用注出栓を示す。
口頸筒２から半割筒５を突設し、さらに該半割筒から挟持板６ａ、６ｂを突設して、該挟持板に透孔７と突起８とを形成する点は図１乃至図４に記載の実施形態と同様であるから、この点についての説明は省略する。
本実施形態では、透孔７を左側の挟持板６ａの右端部に穿設すると共に、突起８を右側の挟持板６ｂの左端部下面から突設し、突起８下部を下方小径のテーパ部に形成する。
【００１９】
上記構成に係る口頸部部材１１を袋１１に装着するには、図９に点線で示すように袋１１の角部に形成した破断線に沿って角部を除去して開口部１２を形成し、上記同様に該開口部に口頸筒２を挿通させ、かつ半割筒５を口頸筒２へ嵌合させると共に、左右の挟持板６ａ、６ｂで開口部１２両側の袋縁部分を挟持させるが、この際、図１１に明示するように透孔７と突起８とを袋１１の外方へ位置させた状態で突起８を透孔７へ挿通させて、突起８のテーパ部端面を透孔７の外縁へ係合させる。
【００２０】
したがって、突起８上部の長さを適当に設定することにより左右の挟持板６ａ、６ｂの挟持力を大にして、挟持板を互いに圧接させることにより挟持板６ａ、６ｂから袋１１が容易に離脱しないようにすることができる。また、請求項５記載のように挟持板下面を互いに噛合い可能な波形状の凹凸面に形成すると、袋１１の離脱防止効果はさらに増大する。
【００２１】
図１２乃至図１８は請求項３、４及び５記載の袋用注出栓を示す。
ここでは説明の重複を避けるため、図５乃至図１１に示す実施形態と異なる点について説明する。
本実施形態では、口頸筒２下部を下方小外径のテーパ筒部に形成する。
また、図１６に示すように、開口部１２両側の袋縁部分に挿通孔１３を穿設しておく。
口頸部部材１を袋１１に装着させるに際しては、左右の挟持板６ａ、６ｂで開口部１２両側の袋縁部分を挟持させることにより、挿通孔１３を介して突起８を透孔７へ挿通させる。
【００２２】
【発明の効果】
請求項１、２及び３記載の発明に係る袋用注出栓は、口頸部部材を袋へ取り付けたので、注出時の液垂れが防止される。
また、口頸部部材は、挟持板を左右に開くだけで袋から取外し可能であり、従って、口頸部部材の再利用が可能になる。
【００２３】
請求項１記載の発明に係る袋用注出栓は、袋縁部を介して突起を透孔へ挿通させるため、袋に孔を設ける必要がなく、このため穿孔工程の省略化が可能になる。
また、袋開口部へテーパ筒を挿通させるので、開口部の口径に製造上の誤差が生じても、テーパ筒と開口部との間に隙間が生ずることがなく、従って、開口部口径の寸法精度を低くすることができる。
【００２４】
請求項２記載の発明に係る袋用注出栓は、突起と透孔とを袋の外方へ位置させた状態で突起を透孔へ挿通させるため、袋に穿孔を施す必要がなく、また突起及び透孔と袋縁又は袋の挿通孔との位置合わせを不要にすることができる。
【００２５】
請求項３記載の発明に係る袋用注出栓は、袋に突起挿通用の孔を形成したので、挟持板から袋が離脱することがない。
また、口頸筒下部をテーパ筒部に形成したため、口頸筒の開口部への挿通が容易になる。
【００２６】
請求項４記載の発明に係る袋用注出栓は、キャップを設けたので、口頸筒の閉塞が容易に行える。
請求項５記載の発明に係る袋用注出栓は、挟持板下面を凹凸面に形成したため、挟持板の袋への装着がさらに強固になる。

【The invention's effect】
Since the mouth-and-neck part member is attached to the bag, the pour-out stopper for the bag according to the inventions of claims 1, 2, and 3 is prevented from dripping during the pour-out.
Further, the mouth / neck member can be removed from the bag simply by opening the holding plate to the left and right, and thus the mouth / neck member can be reused.
[0023]
The bag spout according to the first aspect of the present invention allows the projection to be inserted into the through hole through the bag edge portion, so that there is no need to provide a hole in the bag, and therefore the perforation process can be omitted. .
In addition, since the tapered tube is inserted into the bag opening, even if a manufacturing error occurs in the opening diameter, there is no gap between the tapered tube and the opening. The accuracy can be lowered.
[0024]
The bag spout according to the invention described in claim 2 allows the protrusion to be inserted into the through-hole in a state where the protrusion and the through-hole are positioned outward of the bag, so that there is no need to perforate the bag. It is possible to eliminate the need for alignment between the protrusion and the through hole and the bag edge or the bag insertion hole.
[0025]
In the bag spout according to the invention described in claim 3, since the protrusion insertion hole is formed in the bag, the bag is not detached from the holding plate.
Moreover, since the lower part of the mouth-and-neck tube is formed in the tapered tube part, the insertion into the opening part of the mouth-neck tube becomes easy.
[0026]
Since the bag pouring tap according to the invention described in claim 4 is provided with a cap, the mouth-and-neck tube can be easily closed.
In the bag spout according to the invention described in claim 5, since the bottom surface of the sandwiching plate is formed as an uneven surface, the mounting of the sandwiching plate on the bag is further strengthened.
