以下、この発明の詳細を一実施例を示す図面について説
明する。Hereinafter, details of the present invention will be explained with reference to the drawings showing one embodiment.
第１図（ａ）において１は栓体である。栓体１は栓本体
１３、薄肉体２２及びタブ材１４とからなる。In FIG. 1(a), 1 is a stopper. The plug body 1 consists of a plug body 13, a thin body 22, and a tab material 14.
栓本体１３は、ポリプロピレン、ポリエチレン等の弾性
を有する合成樹脂で構成され、栓胴部ト５とフランジ部
１６とを有する。The stopper body 13 is made of an elastic synthetic resin such as polypropylene or polyethylene, and has a stopper body 5 and a flange 16.
栓胴部１５はほぼ円筒状をなし軸方向に孔１７が形成さ
れており、栓胴部１５の一端１８側の外周部には袋容器
２の底３に取付けるための環状のフランジ部１６が形成
されている。The stopper body 15 has a substantially cylindrical shape with a hole 17 formed in the axial direction, and an annular flange 16 for attaching to the bottom 3 of the bag container 2 is provided on the outer periphery of the stopper body 15 on the one end 18 side. It is formed.
孔１７には内容物取出し用のプラグ４を流体密に揺通し
得る。即ち、孔１７の内壁はプラグ４の外形とほぼ一致
する形状をなすが、途中にプラグ４の径より小さい内径
の環状小径部１９．２１を、軸方向に間隔をあけて形成
されている点が重要である。A plug 4 for removing contents can be fluid-tightly swung through the hole 17. That is, the inner wall of the hole 17 has a shape that almost matches the outer shape of the plug 4, but an annular small diameter portion 19.21 having an inner diameter smaller than the diameter of the plug 4 is formed in the middle at intervals in the axial direction. is important.
環状小径部１９．２１は、縦断面形状が内側に突出する
円弧状をなし、この部分の内径は一定ではないがプラグ
４の経通を弾性変形により許容し、このとき環状小径部
１９．２１においてはその内壁のほぼ全体がプラグ４の
側面に密着するように構成されている。The annular small diameter portion 19.21 has an arcuate longitudinal cross-sectional shape that projects inward, and although the inner diameter of this portion is not constant, it allows the plug 4 to pass therethrough by elastic deformation. is constructed so that almost the entire inner wall thereof is in close contact with the side surface of the plug 4.
環状小径部１９．２１の１ｉ１断面形状は、第１図（ｂ
）に示す栓体１ａの環状小径部１９ａ。The 1i1 cross-sectional shape of the annular small diameter portion 19.21 is shown in Figure 1 (b
) shows an annular small diameter portion 19a of the plug 1a.

密着性を保持し、この密着性が、使用中にプラグ４と栓
本体１３との軸が僅かにずれて傾斜した状態になった場
合でも保たれるような形状とする。21a, it can be a triangular or trapezoidal shape that projects inward, or other shapes, but due to the elastic deformation of the inner wall, almost the entire inner wall of that part maintains close contact with the side surface of the plug 4, The shape is such that this adhesion is maintained even if the axes of the plug 4 and the plug body 13 are slightly deviated and tilted during use.

る。At one end 18 of the stopper body 15, a thin wall 22, which is an inner lining material made of the same material as the stopper body 15 and formed in a sheet shape, is located to close one end of the hole 17. is plug 4
It has the thickness and strength to pierce and destroy.
薄肉体２２としては、第１図（Ｃ）に示す栓体１ｂの薄
肉体２２ａのように、栓胴部１５と一体に構成すること
もできる。The thin body 22 can also be constructed integrally with the stopper body 15, like the thin body 22a of the stopper body 1b shown in FIG. 1(C).
タブ材１４は栓１１部１５の（ｔ！！端２３に剥Ｈ可能
に貼着されて孔１７の他端の開口をυｊ塞している。The tab material 14 is removably attached to the (t!! end 23 of the stopper 11 portion 15) and closes the opening at the other end of the hole 17.

The tip of the captured plug 4 pierces the thin body 22, and the contents flow out of the bag container 2 through the inside of the plug 4. At this time, the side surface of the plug 4 is in close contact with the inner wall of the annular small diameter portion 19.21 while elastically deforming it, and even if the plug 4 is slightly displaced relative to the plug body 1 and the axes of both are inclined, the close contact is maintained. The properties of the plug are maintained and the contents do not leak onto the outside of the plug.
栓体１ａ、１ｂも同様の作用・効果を奏する。The plug bodies 1a and 1b also have similar functions and effects.
