（実施例）
以下、本発明の代表的な実施例を図面に基づいて詳述す
る。(Example) Hereinafter, typical examples of the present invention will be described in detail based on the drawings.
第１図は同実施例を示すものであり、第２図は第１図の
■部拡大図である。FIG. 1 shows the same embodiment, and FIG. 2 is an enlarged view of the section ``■'' in FIG. 1.

フィルムなどから成形されている。In the figure, 10 is a closure body made of metal or plastic, 11 is a sealing material, and 12 is a bottle made of glass, PET, or the like. The sealing material 11 is molded from a heat-shrinkable plastic film or the like in a cup shape that is slightly larger than the outer diameter of the day of the week.

）ときに、シール材１１が封栓本体１０と一体となって
取外されるに十分な接着力を有する程度であれば良い。A layer of pressure sensitive adhesive 14 is provided on the back side of the closure body 10. As the pressure-sensitive adhesive 14, for example, self-adhesive latex containing natural rubber as a main component is used. The layer of adhesive 14 does not necessarily need to be provided on the entire back surface of the closure body 10, and when the closure body 10 is removed (opened) from the day of the week, the sealing material 11 is removed integrally with the closure body 10. It is sufficient as long as it has sufficient adhesive strength to be removed.

体１０を装着する時点でシール材１１との間に装填する
ようにしても良い。In this embodiment, a layer of pressure-sensitive adhesive 14 is provided in advance on the back surface of the sealing body 10, but it may also be provided on the surface of the sealing material 11 that comes into contact with the sealing body 10. Furthermore, the pressure-sensitive adhesive 14 may be prepared separately and loaded between the sealing material 11 and the sealing material 11 when the sealing body 10 is attached on each day of the week.

。この加熱によりシール材１１を収縮させて境目に密着
させ仮シールをする。このとき、シール性を高めようと
する場合は、境目の頂面とシール材１１間に通常のパツ
キン材１３を介装させる。When attempting to seal the boundary with the above sealing cap, first, the sealing material 11 is gently placed on the boundary of the bottle 12 and heated. By this heating, the sealing material 11 is contracted and brought into close contact with the boundary to form a temporary seal. At this time, if the sealing performance is to be improved, a normal packing material 13 is interposed between the top surface of the boundary and the sealing material 11.
また、シール材１１を境目に被せるときの深さは、境目
とシール材の密着性が確保される深さであれば十分であ
り、例えばねし栓の場合にはその深さはねじ部に軽くか
かるか、或は殆んどかからない程度で足りる。In addition, the depth at which the sealing material 11 is applied to the boundary is sufficient as long as the adhesiveness between the boundary and the sealing material is ensured. It is sufficient that it is applied lightly or hardly at all.

圧接着剤１４を介して接着一体化される。After completing the above-mentioned temporary sealing, the sealing body 10 is tightened or screwed in at the boundary. At this time, since there is a layer of pressure-sensitive adhesive 14 on the back surface of the sealing body 10, as the tightening or screwing progresses, the sealing body 10 presses the surface of the sealing material 11, and the pressing force causes the sealing. The material 11 and the sealing body 10 are bonded together via a pressure-sensitive adhesive 14.
こうして密栓された壜１２を開栓するときは、封栓本体
ＩＯを境目から取り外せば、同本体１０と一体になって
シール材１１も同時に境目から外される。When opening the bottle 12 sealed in this manner, the sealing body IO is removed from the border, and the sealing material 11 is also removed from the border at the same time as the main body 10.
図示例は、巻締めキャップ又はねし栓に本発明を適用し
た場合の例であるが、図示しない王冠（打栓をするタイ

。The illustrated example is an example in which the present invention is applied to a tightening cap or a screw stopper, but it goes without saying that the present invention can also be similarly applied to a crown (a type with a stopper), which is not shown.

By using pressure to bond and integrate the sealing material and the sealing body with a pressure-sensitive adhesive, the sealing material and the sealing body are handled separately when sealing, making it easy to manage the sealing quality. The sealing material and the sealing body are integrated and can be removed at the same time, eliminating complications when opening the cap. In particular, in the present invention, for temporary sealing, the sealing material is lightly placed on the border of the container and then heated to shrink and adhere, so the structure of the mechanical device for attaching the sealing material is simple.
