Description
本発明は、ヘアカラー２剤、シャンプー、リンスなどの液状体や調味料などの粉状体を充填するための容器として用いられる口栓付きパウチに関する。 The present invention relates to a pouch with a stopper used as a container for filling liquids such as two hair color agents, shampoos and rinses, and powders such as seasonings.
パウチ用口栓として、上部に雄ネジを有しかつ下部がパウチの開口部に挿入固定されるスパウトと、スパウト上部の雄ネジにねじ合わせられる雌ネジを周壁部に有するキャップとを備えたものが知られている（下記特許文献１等参照）。
ところで、内容物が例えばヘアカラー２剤等の粘性液状体である場合には、注入口の口径をできるだけ大きくして注入作業を容易にかつ迅速に行いたい反面、注出口をより口径の小さいものとして注出量をコントロールし易くしたいという要請がある。
しかしながら、従来のパウチ用口栓にあっては、スパウトが、パウチに内容物を充填する際の注入口と、パウチに充填された内容物を取り出す際の注出口とを兼用するものであって、通常、スパウトの口径が注入口として要求されるサイズに設定されるため、注出口としては口径が大きすぎて注出量のコントロールがし難く、注出作業が困難になるケースがあった。
By the way, when the content is a viscous liquid material such as two hair color agents, it is desirable to make the injection port as large as possible to perform the injection operation easily and quickly, while the spout has a smaller diameter. There is a request to make it easier to control the amount of water dispensed.
However, in the conventional plug for a pouch, the spout serves as both an inlet for filling the contents into the pouch and a spout for taking out the contents filled in the pouch. usually to be set to the size of the diameter of the spout is required as NOTE oN mouth spout as hardly is pouring amount control by diameter is too large, there are cases where the pouring work becomes difficult .
本発明の目的は、パウチへの内容物の注入を容易かつ迅速に行うことができる上、内容物の注出量をコントロールし易いパウチ用口栓を提供することにある。 An object of the present invention is to provide a pouch plug that can easily and quickly inject the contents into the pouch and can easily control the amount of the contents poured out.
本発明によるパウチ用口栓は、上部に雄ネジを有しかつ下部がパウチの開口部に挿入固定されるスパウトと、スパウト上部の雄ネジにねじ合わせられる雌ネジを周壁部に有するキャップと、スパウトの口径よりも小さい口径のノズル部および外向き環状フランジ部を有しかつスパウトの上端部に取り付けられる中栓とを備え、中栓のフランジ部の外周縁に、フランジ部の厚みよりも小さい厚みを有しかつキャップの周壁部内面に係り合わせられる突起が、周方向に間隔をおいて複数形成されていることを特徴としている。
A spout for a pouch according to the present invention has a spout having a male screw at the upper part and a lower part inserted and fixed in the opening of the pouch, and a cap having a female screw screwed to the male screw at the upper part of the spout on the peripheral wall part, A nozzle portion having a smaller diameter than the diameter of the spout and an inner plug attached to the upper end portion of the spout and having an outer annular flange portion, and the outer peripheral edge of the flange portion of the inner plug is smaller than the thickness of the flange portion A plurality of protrusions having a thickness and being engaged with the inner surface of the peripheral wall portion of the cap are formed at intervals in the circumferential direction.
本発明のパウチ用口栓によれば、相対的に口径の大きいスパウトを通じて、パウチへの内容物の注入を容易かつ迅速に行うことができる上、内容物注入後にスパウト上端部に中栓を取り付けることによって、相対的に口径の小さい中栓のノズル部を通じて、内容物の注出を良好に行うことができる。
また、本発明によるパウチ用口栓の場合、中栓をキャップの内側に押し込むようにすれば、そのフランジ部の外周縁に形成された突起がキャップの周壁部内面に係り合わせられ、それによって中栓がキャップに保持される。そして、この中栓付きキャップを、パウチに内容物を充填した後のスパウト上部にねじ嵌めれば、それに伴って中栓の外筒部がスパウト上端部内に強制的に嵌め込まれるため、パウチに充填された内容物がスパウトから溢れ出したりせずに、中栓の装着作業を容易に行うことができる。
According to the pouch plug of the present invention, it is possible to easily and quickly inject the contents into the pouch through a spout having a relatively large diameter, and the inner plug is attached to the upper end of the spout after the contents are injected. Thus, the content can be poured out through the nozzle portion of the inner plug having a relatively small diameter.
Further, in the case of the pouch plug according to the present invention, if the inner plug is pushed into the inside of the cap, the protrusion formed on the outer peripheral edge of the flange portion is engaged with the inner surface of the peripheral wall portion of the cap. The stopper is held in the cap. And if this cap with inner plug is screwed into the upper part of the spout after filling the contents in the pouch, the outer cylinder part of the inner plug will be forcibly fitted into the upper end of the spout. The attached contents can be easily attached without overflowing the spouted contents.
本発明によるパウチ用口栓において、中栓が、スパウトの上端部に強制的に嵌め入れられる外筒部と、外筒部の内周面下部から外筒部内を上方にのびるテーパ筒部と、テーパ筒部の上端に連なって上方突出状に形成された内筒部とを有しており、内筒部によってノズル部が構成されているのが好ましい。 In the pouch plug according to the present invention, the inner plug is forcibly fitted into the upper end portion of the spout, and the tapered tube portion extends upward from the lower portion of the inner peripheral surface of the outer tube portion. It is preferable that the inner cylinder part is formed so as to project upward from the upper end of the tapered cylinder part, and the nozzle part is constituted by the inner cylinder part.
中栓を上記のような構成とすれば、中栓の外筒部がスパウト上端部内に嵌め込まれているため、中栓が外れ難く、また、液状体よりなる内容物がノズル部から垂れ落ちた場合の液溜り部を内筒部と外筒部との間に形成することができるので、使い勝手がよい。 If the inner plug is configured as described above, the outer tube portion of the inner plug is fitted into the upper end of the spout, so that the inner plug is difficult to come off, and the content made of a liquid material hangs down from the nozzle portion. Since the liquid reservoir part in the case can be formed between the inner cylinder part and the outer cylinder part, it is easy to use.
本発明によるパウチ用口栓において、より好ましくは、外向き環状フランジ部が、中栓の外筒部上端に、スパウトの上端面に受けられるように形成されている。 In the pouch plug according to the present invention, more preferably, the outward annular flange portion is formed at the upper end of the outer tube portion of the inner plug so as to be received by the upper end surface of the spout.
上記のようなフランジ部が中栓に形成されていれば、中栓がスパウト上端部内に入り込むのを阻止することができる。 If the flange part as described above is formed in the inner plug, the inner plug can be prevented from entering the upper end of the spout.
本発明によるパウチ用口栓の中栓において、さらに好ましくは、キャップの頂壁部下面に、中栓のフランジ部上面に当接させられる環状下方凸部が形成されている。 In the inner plug of the pouch spout according to the present invention, more preferably, an annular downward convex portion that is brought into contact with the upper surface of the flange portion of the inner plug is formed on the lower surface of the top wall portion of the cap.
上記構成によれば、キャップの環状下方凸部が中栓のフランジ部上面に当接させられることによって、閉栓時のシール性を確保することができる。 According to the said structure, the cyclic | annular downward convex part of a cap is contact | abutted to the flange part upper surface of an inner stopper, and the sealing performance at the time of closure can be ensured.
本発明によるパウチ用口栓において、中栓における外筒部の外周面下部に環状溝が形成されているとともに、環状溝に強制的に嵌め入れられる環状リブがスパウトの上端部内周面に形成されている場合がある。 In the pouch plug according to the present invention, an annular groove is formed in the lower part of the outer peripheral surface of the outer tube portion of the inner plug, and an annular rib forcibly fitted into the annular groove is formed on the inner peripheral surface of the upper end portion of the spout. There may be.
上記の場合、スパウト上端部への外筒部の挿入がスムーズであり、また、強制嵌合に要する力も比較的小さくて済むので、中栓の装着作業が容易である。 In the above case, the outer tube portion can be smoothly inserted into the upper end portion of the spout, and the force required for forced fitting can be relatively small, so that the inner plug can be easily attached.
本発明によるパウチ用口栓において、キャップの頂壁部下面に、中栓のノズル部に嵌め入れられる垂下状のプラグ部が形成されている場合がある。 In the pouch spigot according to the present invention, a drooping plug portion that can be fitted into the nozzle portion of the inner plug may be formed on the lower surface of the top wall portion of the cap.
上記の場合、キャップのプラグ部が中栓のノズル部に嵌め入れられることによって、シール性が確保されるので、内容物の漏れ等のおそれがない。
また、上記の場合、スパウト上端部への装着前の中栓をキャップの内側に押し込めば、中栓のノズル部にキャップのプラグ部が嵌め入れられることによって、中栓がキャップに保持されるため、この中栓付きキャップを、パウチに内容物を充填した後のスパウト上部にねじ嵌めれば、それに伴って中栓の外筒部をスパウト上端部内に強制的に嵌め込むことができる。従って、上記の場合、中栓のフランジ部に前述のような突起を形成しなくても、突起を形成した場合と同様の効果が得られる。もっとも、中栓をより安定的に保持できる点では、キャップのプラグ部および中栓のプラグ部の両方が形成されているのが好ましい。
In the above case, since the sealing portion is secured by fitting the plug portion of the cap into the nozzle portion of the inner plug, there is no risk of leakage of the contents.
Also, in the above case, if the inner plug before being attached to the upper end of the spout is pushed into the inside of the cap, the plug portion of the cap is fitted into the nozzle portion of the inner plug so that the inner plug is held by the cap. If the cap with the inner plug is screwed into the upper part of the spout after the pouch is filled with the contents, the outer cylinder portion of the inner plug can be forcibly fitted into the upper end of the spout. Therefore, in the above case, the same effect as when the protrusion is formed can be obtained without forming the protrusion as described above on the flange portion of the inner plug. However, it is preferable that both the plug portion of the cap and the plug portion of the inner plug are formed in that the inner plug can be held more stably.
また、本発明によるパウチ用口栓において、キャップの頂壁部下面に、中栓のノズル部上端面に当接させられるシール部が形成されている場合もある。 In the pouch spigot according to the present invention, a seal portion that is brought into contact with the upper end surface of the nozzle portion of the inner plug may be formed on the lower surface of the top wall portion of the cap.
上記の場合、キャップのシール部が中栓のノズル部上端面に当接させられることによって、より優れたシール性が得られる。シール部は、好適には、パッキン等のシール部材をキャップの頂壁部下面に接合することによって形成される。 In the above case, the sealing portion of the cap is brought into contact with the upper end surface of the nozzle portion of the inner plug, so that more excellent sealing performance is obtained. The seal portion is preferably formed by joining a seal member such as packing to the lower surface of the top wall portion of the cap.
次に、本発明による口栓付きパウチは、前述した本発明による口栓を備えてなるものである。 Next, a pouch with a plug according to the present invention comprises the plug according to the present invention described above.
本発明の口栓付きパウチによれば、相対的に口径の大きいスパウトを通じて、パウチへの内容物の注入を容易にかつ迅速に行うことができる上、内容物注入後にスパウト上端部に中栓を取り付けることによって、相対的に口径の小さい中栓のノズル部を通じて、内容物の注出を良好に行うことができるので、例えばヘアカラー２剤等の粘性液状体の容器として好適に使用することができる。 According to the pouch with a plug of the present invention, the contents can be easily and quickly injected into the pouch through a spout having a relatively large diameter, and an inner plug is attached to the upper end of the spout after the contents are injected. By attaching, the content can be favorably poured out through the nozzle part of the inner plug having a relatively small diameter, so that it can be suitably used, for example, as a container for viscous liquid materials such as two hair color agents. it can.
また、本発明による包装体は、前述した本発明による口栓付きパウチに内容物が充填されてなるものである。 The package according to the present invention is formed by filling the contents of the above-mentioned pouch with a stopper according to the present invention.
上記の包装体にあっては、パウチに充填された内容物を中栓のノズル部を通じて注出させることができるため、注出量をコントロールしやすく、使い勝手がよい。 In the above package, the contents filled in the pouch can be poured out through the nozzle portion of the inner plug, so that the amount of dispensing is easy to control and easy to use.

次に、図２を参照して、口栓（２）付きパウチ（１）の閉栓工程を説明する。
まず、図２（ａ）に示すようにキャップ（４）の内側に中栓（５）を押し込んで、中栓（５）のノズル部（５１）（内筒部（５Ｃ））にキャップ（４）のプラグ部（４４）を嵌め込むことにより、中栓（５）がキャップ（４）に保持された状態とする。
一方、パウチ（１）の開口部（１１）に、スパウト（３）の基部（３Ａ）を挿入して、基部（３Ａ）外面をヒートシールによりパウチ（１）に接合する（図２（ｂ）参照）。
そして、スパウト（３）を通じてパウチ（１）に液状体等の内容物を充填した後、図２（ｂ）に示すように、スパウト（３）の上部に中栓（５）付きキャップ（４）をねじ嵌めていく。そうすると、中栓（５）の外筒部（５Ａ）がスパウト（３）の注出部（３Ｂ）の上端部に挿入され、外筒部（５Ａ）の下端がスパウト（３）内周面の環状リブ（３６）を乗り越えることによって、環状リブ（３６）が中栓（５）の環状溝（５４）に強制的に嵌め入れられる。この際、中栓（５）のフランジ部（５３）上面がキャップ（４）の環状下方凸部（４３）によって上方から押さえつけられるため、キャップ（４）をねじ嵌めるための力が中栓（５）に伝わり易く、それによって環状リブ（３６）と環状溝（５４）との嵌合がより簡単にかつ確実に行われる。また、環状リブ（３６）が環状溝（５４）に嵌め入れられると、その時点で中栓（５）のフランジ部（５３）下面がスパウト（３）の上端面に受けられるので、中栓（５）は、それ以上はスパウト（３）の中に入り込まない。
以上の通り、比較例の口栓（２）によれば、キャップ（４）のねじ嵌め操作によって、それと同時にスパウト（３）上端への中栓（５）の装着が簡単に行えるため、特別な装置を使用しなくても、パウチ（１）に充填された内容物が溢れ出したりすることなく、パウチ（１）の閉栓作業を効率良く実施して、包装体を得ることができる。
Next, with reference to FIG. 2, the capping process of the pouch (1) with a stopper (2) is demonstrated.
First, as shown in FIG. 2A, the inner plug (5) is pushed inside the cap (4), and the cap (4) is inserted into the nozzle part (51) (inner cylinder part (5C)) of the inner plug (5). ), The inner plug (5) is held by the cap (4).
On the other hand, the base (3A) of the spout (3) is inserted into the opening (11) of the pouch (1), and the outer surface of the base (3A) is joined to the pouch (1) by heat sealing (FIG. 2B). reference).
And after filling a pouch (1) with contents, such as a liquid body, through a spout (3), as shown in FIG.2 (b), a cap (4) with an inside plug (5) is attached to the upper part of a spout (3). Fit the screw. Then, the outer cylinder part (5A) of the inner plug (5) is inserted into the upper end part of the spout part (3B) of the spout (3), and the lower end of the outer cylinder part (5A) is the spout (3) inner peripheral surface. By getting over the annular rib (36), the annular rib (36) is forcibly fitted into the annular groove (54) of the inner plug (5). At this time, since the upper surface of the flange portion (53) of the inner plug (5) is pressed from above by the annular lower convex portion (43) of the cap (4), the force for screwing the cap (4) is increased. ), Whereby the annular rib (36) and the annular groove (54) can be more easily and reliably engaged. Further, when the annular rib (36) is fitted into the annular groove (54), the lower surface of the flange portion (53) of the inner plug (5) is received by the upper end surface of the spout (3) at that time. 5) does not go into the spout (3) any more.
As described above, according to the spigot (2) of the comparative example , the cap (4) can be easily fitted into the upper end of the spout (3) at the same time by screwing the cap (4). Even if the device is not used, the contents filled in the pouch (1) do not overflow, and the pouch (1) can be efficiently closed to obtain a package.

That is, the pouch plug (2) shown in FIGS. 4 and 5 is related to the outer peripheral edge of the flange portion (53) of the inner plug (5) and the inner surface of the peripheral wall portion (4A) of the cap (4). A plurality of projections (55) to be aligned are formed at intervals in the circumferential direction. More specifically, the protrusions (55) have a thickness slightly smaller than half the thickness of the flange portion (53), and a total of four protrusions are formed at equal intervals in the circumferential direction of the flange portion (53). Has been.
この第１実施形態の場合、中栓（５）をキャップ（３）の内側に押し込むようにすれば、そのフランジ部（５３）の外周縁に形成された突起（５５）がキャップ（４）の周壁部（４Ａ）内面に係り合わせられる。したがって、中栓（５）は、比較例の場合と比べて、より確実にキャップ（４）に保持されるので、スパウト（３）の上端部に取り付ける際にキャップ（４）から脱落したり位置ズレを起こしたりするおそれがより少なくなり、作業の信頼性が向上する。
In the case of this first embodiment, if the inner plug (5) is pushed into the inside of the cap (3), the protrusion (55) formed on the outer peripheral edge of the flange portion (53) is formed on the cap (4). The peripheral wall (4A) is engaged with the inner surface. Accordingly, since the inner plug (5) is more securely held by the cap (4) than in the comparative example , the cap (4) may be detached from the cap (4) when attached to the upper end of the spout (3). There is less risk of misalignment and work reliability is improved.
