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 the mouth of the embankment body and the cap. It is designed to be able to be fitted, and in particular, the purpose is to easily and reliably fit the inner stopper.

中栓を有する増体は、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増体日部内に嵌め込むことが
行なわれている。In the case of an extender with an inner stopper, the inner stopper and the cap are fitted together when the contents are filled, but in order to improve work efficiency, the inner stopper is assembled into the cap in advance.
The inner stopper and the cap are fitted into the growth area at the same time.

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

べく上述の組み付きを強固のものとすると、使用開始に
際してキャップを堤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 that when the cap was removed from the mouth of the embankment body, even the inner stopper fell out.

ものであり、以下その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 embankment body, and loosens the assembly between the cap and the inner plug after it is fitted into the mouth of the embankment. This is intended to ensure a firm fit between the mouth part and the mouth part, and examples thereof will be described below with reference to the drawings.

先ず１０は化粧水等を収納する増体であって、その口部

の内面には、上述した堤体口部１１の螺溝１２に螺合す
る螺溝２４が刻み込まれている。Reference numeral 20 denotes a cap body in the shape of a top plate, and the center of the lower surface of the top plate 21 has an engaging portion 22 a that bulges outward.
A retaining piece 22 with a
A threaded groove 24 is cut into the inner surface of the embankment to be threaded into the threaded groove 12 of the above-described embankment body mouth portion 11.

次いで３０は軟質合成樹脂材料による弾性変形が可能な

３２が内方向に膨出して設けられている。Next, reference numeral 30 denotes an elastically deformable crested plate-shaped inner stopper made of a soft synthetic resin material, and a retaining part 32 that engages with the inner surface of the peripheral wall 31 over the same strip 13 of the embankment body mouth part 11. is provided to bulge inward.

また、頂部３３の中央部は凹部３４となっていて、前記
キャップ体頂板２１から垂下設された保合片２２に対応

係合部２２ ａと係合する保合部３４ ｂが、内方向に
膨出して設けられている。Further, the center portion of the top portion 33 is a recess 34, and a vertical surface 34a of the recess at a position corresponding to the retaining piece 22 hanging down from the cap body top plate 21 is provided with a vertical surface 34a for engagement of the engaging piece 22. A retaining portion 34b that engages with the portion 22a is provided to bulge inward.

即ち、キャップ体２０と中栓３０との組み付きは、キャ

体口部１１と中栓３０との組み付きは、中栓周壁３１内
面の係合部３２が増体口部１１の側条１３を乗り越えて
係合して達成されるのである（第２図参照）。That is, the assembly of the cap body 20 and the inner plug 30 is such that the engaging portion 22a of the engaging piece 22 of the cap body 20 engages by exceeding the retaining portion 34b of the inner plug 30 from above. (See Fig. 1), and the assembly of the growth opening part 11 and the inner plug 30 is ensured when the engaging part 32 on the inner surface of the inner plug peripheral wall 31 is on the side of the growth opening part 11. This is achieved by getting over the strip 13 and engaging (see Figure 2).

ところで、中栓：３０に於ける周壁３１の内径は増体口

０の係合部２２ ａと中栓３０の係合部３４ ｂとの係
合がゆるんでほぼ解除される程度の寸法となっている。By the way, the inner diameter of the peripheral wall 31 of the inner stopper 30 is considerably smaller than the outer diameter of the expansion opening 11, and when the inner stopper 30 is fitted into the opening 11, the side strips 13 The inner stopper 30 is elastically deformed in an outwardly extending manner due to the engagement of the retaining portion 32 with the inner stopper 30, and thereby the cap body 2
The dimensions are such that the engagement between the engagement part 22a of the inner plug 30 and the engagement part 34b of the inner stopper 30 is loosened and almost released.

つまりキャップ体用と中栓３０とは、一方の係合部２２
ａが外方向に、他方の保合部３４ ｂが内方向に夫々
膨出していて上下方向の組み付きがなされているので、
上述のように中栓３０が増体口部１１に無理に嵌め込ま

ずれし、従ってこの保合部３４ ｂとキャップ体２０の
係合部２２ ａとの係合がゆるめられることになるので
ある。In other words, the one for the cap body and the inner stopper 30 are
Since the retaining portion a bulges outward and the other retaining portion 34b bulges inward, they are assembled in the vertical direction.
As a result of the inner stopper 30 being forcefully fitted into the expansion opening 11 as described above, the inner stopper 30, especially the top plate 33, is pulled outward, and the bulging retaining part 34b is also pulled outward. As a result, the engagement between the retaining portion 34b and the engaging portion 22a of the cap body 20 is loosened.

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、増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増体口部に嵌め
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, and the inner stopper and the cap body will not come apart during the assembly process. It becomes possible to simultaneously and extremely easily fit the two into the enlargement opening.

しかも、この口部への嵌め込みに際し、中栓の周壁内径

際してキャップ体のみを増体口部から取り外すことが出
来るのである。Moreover, when fitting into this opening, the inner diameter of the peripheral wall of the inner plug is smaller than the outer diameter of the opening, so the assembly of the inner plug into the enlarged opening is extremely strong and perfect. As a result, the connection between the cap body and the inner stopper is loosened and almost released, and only the cap body can be removed from the expansion 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 during use.
