実に達成せんとするものである。[Detailed description of the invention] The present invention relates to a structure related to a structure mouth and a cap, and after filling the embankment body with contents, the inner stopper and the cap body are simultaneously fitted into the structure mouth. In particular, the purpose is to easily and reliably fit the inner stopper.

中栓を有する堤体は、内容物が充填された段階で中栓と
キャップとが嵌め込まれる訳であるが、作業能率を向上
させる為に、予め中栓をキャップ内に組み込んでおき、
中栓とキャップとを同時に堤体口部内に嵌め込ませよう
とすることが行なわれている。In the case of an embankment body having an inner stopper, the inner stopper and the cap are fitted into each other when the contents are filled, but in order to improve work efficiency, the inner stopper is assembled into the cap in advance.
Attempts have been made to simultaneously fit the inner stopper and the cap into the mouth of the embankment body.

しかしながら、流れ作業の中にあって、予めキャップに
組み込まれた中栓は、震動等によってその組み付きが外
れてしまうことが多々見られ、またこの不都合を避ける
べく上述の組み付きを強固のものとすると、使用開始に
際してキャップを構体口部から外すときに中栓までもが
脱は出てしまう欠点が存したのである。However, during assembly line operations, the inner stopper that has been assembled into the cap in advance often comes unattached due to vibrations, etc., and in order to avoid this inconvenience, the above-mentioned assembly is strengthened. There was a drawback in that when the cap was removed from the mouth of the structure at the beginning of use, even the inner stopper fell out.

ャップと中栓との組み付きを強固のものとし、口部への
嵌め込み後はキャップと中栓との組み付きをゆるめてほ
ぼ解除させると共に中栓と口部との嵌め込みを強固にな
さんとするものであり、以下その一実施例を図面に従っ
て説明する。Therefore, the present invention makes the assembly between the cap and the inner plug strong before it is fitted into the mouth of the structure, and after the cap and the inner plug are fitted into the mouth, the assembly between the cap and the inner plug is loosened and almost released. This is intended to ensure a firm fit between the inner stopper and the opening, and one embodiment thereof will be described below with reference to the drawings.

先ず１０は化粧水等を収納する堤体であって、その口部
１１の外周面に螺溝１２を刻み込んだものである。First, reference numeral 10 is a bank body for storing lotion, etc., and a spiral groove 12 is carved into the outer circumferential surface of the mouth portion 11 of the bank body 10.

また２０は有頂板部形状のキャップ体であって、その周
壁２１の内面には上述した構体口部１１の螺溝１２に螺
合する螺溝２２が刻み込まれてあり、更にこの周壁２１
内面の上端部には内方向に膨出した保合部２３が設けら
れている。Reference numeral 20 denotes a cap body in the shape of a top plate, and the inner surface of its peripheral wall 21 has a threaded groove 22 that is threadedly engaged with the threaded groove 12 of the structure opening 11 described above.
A retaining portion 23 that bulges inward is provided at the upper end of the inner surface.

次いで３０は軟質合成樹脂材料による弾性変形が可能な
有底板部形状の中栓であって、前述の増体口部１１内に
ぴったりと嵌入する周壁３１の外周面上端に鍔部３２を
周設し、更に当該鍔部３２の周端に外方向に突出する態
様で保合片３３が設けられている。Next, 30 is a bottomed plate-shaped inner plug made of a soft synthetic resin material that can be elastically deformed, and a flange 32 is provided around the upper end of the outer peripheral surface of a peripheral wall 31 that fits snugly into the aforementioned expansion opening 11. Furthermore, a retaining piece 33 is provided at the peripheral end of the flange 32 in such a manner as to protrude outward.

従って中栓３０を前記キャップ体２０内に嵌め込むと、
上述の保合片３３は内方に押される如くして弾性変形し
てキャップ体周壁２１内面の係合部２３に当接係合し、
もって中栓３０はキャップ体２０内に確固と組み付くこ
ととなるのである（第１図参照）。Therefore, when the inner stopper 30 is fitted into the cap body 20,
The above-mentioned retaining piece 33 is pushed inward and elastically deforms to abut and engage with the engaging portion 23 on the inner surface of the cap body peripheral wall 21,
As a result, the inner stopper 30 is securely assembled within the cap body 20 (see FIG. 1).

尚、図示例では鍔部３２の周端上部もまたキャップ体２
０内面上端に密接するようになっていて上述の保合を補
なっている。In the illustrated example, the upper peripheral end of the flange 32 is also connected to the cap body 2.
0 is in close contact with the upper end of the inner surface to supplement the above-mentioned retention.

ところで中栓３０は、鍔部３２下面が堤体口部１１上端
面に密接するようにして口部１１内に密嵌入されるので
あるが、この中栓３０に於ける周壁２１の外径は、上記
口部１１の内径よりも充分大きなものとなっており、中
栓３０を口部１１内にぴったりと嵌入したときに、殊に
鍔部３２が内方向に位置ずれする態様で弾性変形し、且
つそれによってキャップ体２０の係合片３３による係合
がゆるめられる程度の寸法となっている。By the way, the inner plug 30 is tightly fitted into the mouth part 11 so that the lower surface of the flange part 32 is in close contact with the upper end surface of the embankment body mouth part 11, but the outer diameter of the peripheral wall 21 in this inner plug 30 is , is sufficiently larger than the inner diameter of the opening 11, and when the inner stopper 30 is tightly fitted into the opening 11, the flange 32 is elastically deformed in such a manner that it is displaced inwardly. , and has a size that allows the engagement by the engagement piece 33 of the cap body 20 to be loosened.

従って周壁２１の外面下部は上述の嵌入がしやすいよう
にテーパー面としておくのがよいであろう。Therefore, it is preferable that the lower part of the outer surface of the peripheral wall 21 has a tapered surface to facilitate the above-mentioned fitting.

つまり、キャップ体２０と中栓３０との係合は、常に外
方向へ弾性復帰しようとする係合片３３が係合部２３を
押圧することによって遠戚されているのであるから、上
述のように中栓３０を口部１１内に無理に嵌め込まれる
結果、中栓３０の鍔部３２が内方向に位置ずれし、よっ
て上述の如く保合がゆるめられて解かれることになるの
である。In other words, the engagement between the cap body 20 and the inner stopper 30 is achieved by the engagement piece 33, which always tries to elastically return outward, pressing the engagement portion 23, as described above. As a result of the inner stopper 30 being forcefully fitted into the mouth portion 11, the flange 32 of the inner stopper 30 is displaced inwardly, and as a result, the attachment is loosened and released as described above.

本考案は、以上説明したような構成、作用を営む。The present invention has the configuration and operation as explained above.

従って、キャップ体と中栓との組み付きが強固である為
に、流れ作業の工程にあってその組み付きが解けてしま
うことはなく、構体内に内容液を充填した段階で中栓と
キャップ体とを同時に且つ極めて簡単に構体口部に嵌め
込むことが可能となる。Therefore, since the assembly between the cap body and the inner stopper is strong, the assembly will not come undone during the assembly process, and the inner stopper and the cap body will not come apart during the assembly process. can be fitted into the structure mouth at the same time and extremely easily.

しかも、この口部への嵌め込みに際し、中栓の周壁外径

るのである。Moreover, when fitting into this opening, the outer diameter of the peripheral wall of the inner plug is larger than the inner diameter of the opening, so the assembly of the inner plug into the structural opening is extremely strong and can be carried out snugly. This causes the cap body and the inner stopper to become loosely bonded and are almost released, so that only the cap body can be removed from the body opening when used.

故に本考案は、各部材の相互の組み付きが強固であって
作業能率の向上を得ることが出来、且つ使用に際しては
支障がない極めて有効なものなのである。Therefore, the present invention is extremely effective because the mutual assembly of each member is strong, the work efficiency can be improved, and there is no problem in use.
