どから成形されている。In the figure, 10 is a sealing 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 formed from a cup-shaped plastic film having a heat shrinkability, which is made slightly larger than the outer diameter of the bottle mouth.
封栓本体10の裏面には感圧接着剤14の層が設けられる。

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 surface of the closure body 10.
As the pressure-sensitive adhesive 14, for example, a self-adhesive latex containing natural rubber as a main component is adopted. Same adhesive
The 14 layers do not necessarily have to be provided on the entire back surface of the closure body 10, and when the closure body 10 is removed from the bottle mouth (opened), the sealing material 11 is removed together with the closure body 10. It is sufficient if it has a sufficient adhesive force.

い。In this embodiment, the layer of the pressure-sensitive adhesive 14 is preliminarily coated with the sealing body 10
Although it may be provided on the contact surface of the sealing material 11 with the sealing body 10, the pressure-sensitive adhesive 14 is separately prepared and sealed in a bottle mouth. The plug body 10 may be loaded between the sealing material 11 and the sealing body 11 at the time of bonding.

合は、壜口の頂面とシール材11間に通常のパッキン材13
を介装させる。When attempting to seal the bottle with the above-mentioned plug, first, the bottle 12 is covered with the sealing material 11 gently and heated. By this heating, the sealing material 11 is shrunk so as to be brought into close contact with the bottle mouth and temporarily sealed. At this time, if it is desired to improve the sealing property, a normal packing material 13 should be provided between the top surface of the bottle and the sealing material 11.
Intervene.
また、シール材11を壜口に被せるときの深さは、壜口と
シール材の密着性が確保される深さであれば十分であ

して接着一体化される。After finishing the temporary seal, tighten the closure body 10 around the bottle,
Or screw it in. At this time, since there is a layer of pressure-sensitive adhesive 14 on the back surface of the closure body 10, the closure body 10 presses the surface of the sealing material 11 as the winding or screwing progresses, and the pressing force seals. The material 11 and the plug body 10 are bonded and integrated 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10

The sealing material and sealing body are bonded and integrated via pressure-sensitive adhesive by pressure, so that the sealing material and the sealing body are handled separately when sealing, and the sealing property is easy to manage. The sealing material and the body of the sealing plug can be integrated and removed at the same time, and the complexity of opening the plug can be eliminated. In particular, in the present invention, for temporary sealing, the sealing material is lightly covered on the bottle mouth, and then contracted and adhered only by heating, so that the mechanical structure for mounting the sealing material is simple.
