Utility Model Registration No. 2568899 Specification

ところで、従来の二剤混合容器は、部品点数が多く効率的な組立てができないことから製造コストの上昇が避けられない不具合があり、しかも、中栓を取り外す収納部の回転操作に伴って容器の長さ（全高）が変動（長くなったり短くなったりする）するため使い勝手が良いとは言えないのが現状であった。   By the way, the conventional two-component mixing container has a problem that an increase in manufacturing cost is unavoidable due to the large number of parts that cannot be efficiently assembled. At present, the length (overall height) fluctuates (becomes longer or shorter), so it is not easy to use.

また、この種の容器は、商品の流通段階での不正な開封を目視でもって確認できるように、バージンリングを備えたものが存在する（特許文献２参照）が、容器の開封に際して該バージンリングは容器から完全に切り離された分離ごみとして別途、廃棄処理されており、同一種類の素材を回収して資源の再利用を図る観点からも好ましくない。
特開２００２−３２６６７１号公報 In addition, there are containers of this type that are provided with a virgin ring so that unauthorized opening in the product distribution stage can be visually confirmed (see Patent Document 2). Is separately disposed as separated waste completely separated from the container, which is not preferable from the viewpoint of collecting the same type of material and reusing resources.

図３〜図６は、上掲図1、２に示した構造の二剤混合容器を基本構造とした本発明にしたがう二剤混合容器の実施の形態を示したもの（請求項１に対応しており、符号１〜１１は図1、２に示したものと同じ。）であり、図における１２はバージンリングである。このバージンリング１２は先端方向内壁に上収納部１の外周壁に設けられた縦リブ（あるいは縦溝）１ｃに適合する縦溝（あるいは縦リブ）１２ａを有しており、これを廻り止めとすることで容器の開封前における上収納部１と中間筒体（下収納部を含む）５の相対的な回転を防止する。
3 to 6 show an embodiment of a two-component mixing container according to the present invention having the basic structure of the two-component mixing container having the structure shown in FIGS. 1 and 2 (corresponding to claim 1). 1 to 11 are the same as those shown in FIGS. 1 and 2), and 12 in the figure is a virgin ring. The virgin ring 12 has a longitudinal groove (or longitudinal rib) 12a adapted to a longitudinal rib (or longitudinal groove) 1c provided on the outer peripheral wall of the upper storage portion 1 on the inner wall in the front end direction. This prevents relative rotation of the upper storage portion 1 and the intermediate cylinder (including the lower storage portion) 5 before the container is opened.

また、図における１３はバージンリング１２と中間筒体５とを破断可能に一体連結する結合片、１４は中間筒体５の上端に一体的に設けられた傾斜付き凸部、１５はバージンリング１２の下端に一体的に設けられ該傾斜付き凸部１４に適合する傾斜付き凹部である。   Further, in the figure, reference numeral 13 denotes a connecting piece that integrally connects the virgin ring 12 and the intermediate cylinder 5 so as to be breakable, reference numeral 14 denotes an inclined convex portion integrally provided at the upper end of the intermediate cylinder 5, and reference numeral 15 denotes a virgin ring 12. It is a recessed part with a slope which is integrally provided in the lower end of this, and fits the convex part 14 with a slope.

図３〜６に示した二剤混合容器は、開封前の状態を図５に示す如く、バージンリング１２と中間筒体５は結合片１３を介してつながっており、縦リブ１ｃ及び縦溝１２ａにより廻り止めされており、容器の開封前においては上収納部１と中間筒体（下収納部３を含む）５の相対的な回転は防止されている。

 In the two-component mixing container shown in FIGS. 3 to 6 , the virgin ring 12 and the intermediate cylinder 5 are connected via the coupling piece 13 as shown in FIG. 5 in the state before opening, and the vertical rib 1c and the vertical groove 12a are connected. The upper storage part 1 and the intermediate cylinder (including the lower storage part 3) 5 are prevented from rotating relative to each other before the container is opened.

一方、容器内の内容物を混合して使用に供すべく中間筒体５を回転させると、該中間筒体５の傾斜付き凸部１４の傾斜面にバージンリング１２の傾斜付き凹部１５の傾斜面が沿って移動し、このとき、図６に示すように、バージンリング１２は中間筒体５から切り離され、前記縦リブ（又は縦溝）１ｃに案内されて上方へと移動することとなり、その行き止まり端で図７に示す如く、縦溝（又は縦リブ）１２ａの基底面（縦リブの場合は頂面）及び縦リブ（又は縦溝）１ｃの頂面（溝の場合は基底面）に形成した小突起ｐ、ｐ′によりアンダーカット嵌合して上収納部１に係留され、これによりバージンリング１２が分離ごみとなることはない。   On the other hand, when the intermediate cylinder 5 is rotated to mix and use the contents in the container, the inclined surface of the inclined concave portion 15 of the virgin ring 12 is added to the inclined surface of the inclined convex portion 14 of the intermediate cylindrical body 5. At this time, as shown in FIG. 6, the virgin ring 12 is cut off from the intermediate cylinder 5 and guided upward by the vertical rib (or vertical groove) 1c. At the dead end, as shown in FIG. 7, on the base surface (vertical surface in the case of vertical ribs) of the vertical groove (or vertical rib) 12a and the top surface (base surface in the case of grooves) of the vertical rib (or vertical groove) 1c. The formed small protrusions p and p ′ are undercut and are anchored to the upper storage portion 1, whereby the virgin ring 12 does not become separated garbage.

上記の例では、バージンリング１２を中間筒体５に結合片１３を介してつないだ場合について示したが、該バージンリング１２を結合片１３を介して上収納部に連結する（請求項２に対応）ことにより、上記縦リブ（あるいは縦溝）１ｃと縦溝（あるいは縦リブ）１２ａの配置関係は逆転して設けられることとなり、その動きも上方への移動から下方への移動となる。

In the above example, the case where the virgin ring 12 is connected to the intermediate cylinder 5 via the coupling piece 13 is shown. However, the virgin ring 12 is connected to the upper storage portion via the coupling piece 13 (claim 2). Accordingly, the arrangement relationship between the vertical rib (or vertical groove) 1c and the vertical groove (or vertical rib) 12a is reversed, and the movement also changes from upward to downward.

縦溝１２ａを縦リブとして縦リブ１ｃ同士で廻り止めを構成してもよく、この場合、アンダーカット嵌合に係留するための小突起は縦リブの側面に設けることができる。また、縦リブ（あるいいは縦溝）１ｃ及び縦溝１２ａは少なくとも１つ設けることが可能であり、その設置個数は限定されない。   The vertical grooves 1a may be used as the vertical ribs to prevent rotation between the vertical ribs 1c.
