ようになっている。The venting valve label A has a square base film 2 in which a vent 2a communicating with a gas vent hole of a sealed bag is formed at the center, and an upper surface of the square base film 2 having the same shape as the base film 2. The base film has a three-layer film structure including a cover film 4 laminated via an adhesive layer 3 and two opposing reinforcing sheets 5, 5 laminated on both measuring portions on the cover film 4. The pressure-sensitive adhesive layer 3 between the base film 2 and the cover film 4 is formed on both sides of the base film 2. A non-adhesive band 6 on which the adhesive layer 3 is not formed is formed in the central band leading to. The exposed surface 4a of the cover film 4 and the exposed surface 2b of the base film 2 in the non-adhesive band 6 are in contact with each other. Doing Sealing liquid such as silicone oil is filled in the non-adhesive band 6. Further, the reinforcing sheets 5, 5 are laminated at such a position that these opposed edges 5 a, 5 a are slightly inside the edges 6 a, 6 a of the non-adhesive strip 6, and press the cover film 4 to cover the cover film 4. The exposed surface 4a of the film is brought into contact with the exposed surface 2b of the base film.

It is to apply, but it is complicated to apply the adhesive on both sides in this way, it is difficult to accurately position the end forming the non-adhesive band,
There was a manufacturing problem. In addition, the exposed surface 2b of the base film and the exposed surface 4a of the cover film correspond to the thickness of the adhesive layer 3.
Are separated from each other, so that a relatively large amount of sealing liquid must be filled in order to completely close the non-adhesive strip 6, and as a result, the sealing liquid oozes out of the valve label, and the sealing is performed. There was a problem that the outer surface of the bag was stained.

流出するおそれが少ない。The degassing valve label of the present invention has the same function as the above-described degassing valve label, and adheres the vent hole of the base film in correspondence with the vent hole of the sealing bag. A base film and an adhesive layer formed on the entire lower surface, and a belt-like coating layer extending from one end to the other end of the base film on the adhesive layer and passing through a portion facing the air hole. Formed with a cover film, comprising two reinforcing sheets facing each other laminated on both sides of the cover film, the cover film is adhered to the base film by an adhesive layer, and the belt-shaped The coating layer forming portion is in a non-adhered state with the base film due to the interposition of the sealing liquid, and a gas for allowing the high-pressure gas from the vent hole of the base film to escape between the strip-shaped coating layer and the base film to the outside. Since the discharge path was used, the coating layer on the pressure-sensitive adhesive layer can be easily and accurately formed by printing or other means, and the coating layer thus formed has a very small thickness. Since it is provided on the pressure-sensitive adhesive layer formed on the entire lower surface of the cover film, it slightly protrudes from the pressure-sensitive adhesive layer, so that the coating layer surface adheres well to the base film surface and shuts off gas in the gas exhaust passage. The sealing effect is high, the ventilation holes in the base film are securely closed, the sealing of the sealing bag can be securely maintained, and the amount of the sealing liquid is extremely small, and the sealing liquid may flow out of the label. Less is.

ものである。Although not shown, the degassing valve film 1 of the present invention usually has an adhesive applied to the lower surface of the base film 2 and the surface of the adhesive is protected by a release sheet. Then, the air holes 2a of the cover film 2 are adhered to the gas vent holes of the sealing bag so as to correspond to the gas vent holes. If the internal pressure of the sealed bag is substantially equal to the atmospheric pressure, the surface of the coating film layer 7 is in close contact with the surface of the base film 2 and the sealing liquid is filled between them. Is closed, so that the ventilation holes 2a of the base film 2 are closed, so that no gas flows into and out of the sealing bag, and the sealing of the sealing bag is maintained. When high-pressure gas is generated from the contents of the sealing bag in this state, the high-pressure gas passes through the vent hole 2a of the base film 2 and the surface of the coating layer 7 of the gas discharge passage 8 through the vent hole of the sealing bag. The adhesive layer 3 and the cover film 4 are pushed up through the
The surface of the film layer 7 and the surface of the coating layer 7 are released from close contact to form a gap between them, thereby passing through the gas discharge passage 8 and escaping out of the sealed bag. When the gas having a pressure higher than the atmospheric pressure escapes to the outside as described above, when the high pressure state in the sealed bag is eliminated, the pressing force on the cover film 4 by the high pressure gas is released, and the gas is pressed by the reinforcing sheet. The cover film 4 is elastically restored, the state of close contact between the surface of the base film 2 and the surface of the coating film layer 7 is restored, and the gas exhaust passage 8 is returned to its original closed state. Therefore, the inside of the sealed bag and the outside air are shut off again, and the sealed state of the sealed bag is maintained.

As the printing ink, any type of ink can be used as long as it can lose the adhesive force of the adhesive on its surface, and is preferably of a type that can withstand a sealing liquid such as silicone oil.

したガス抜き弁フィルムＡと異なるところである。The degassing valve label 1 is formed by laminating three layers of films, and the gas discharge passage 8 is formed by applying an adhesive to the entire lower surface of the cover film 4 and then coating the adhesive layer 3 with a coating layer. 7 can be formed by printing, so that the structure is simple, easy to manufacture and low cost. The coating layer 7 on the pressure-sensitive adhesive layer 3 of the cover film 4 that closes the ventilation holes 2 a of the base film 2 is applied on the pressure-sensitive adhesive layer 3 formed on the entire lower surface of the cover film 4. Therefore, the coating layer 7 slightly protrudes from the pressure-sensitive adhesive layer 3 by the thickness thereof, and both ends of the coating layer 7 of the cover film 4 are pressed toward the base film 2 by the ends of the reinforcing sheets 5 and 5. Therefore, the surface of the coating layer 7 is firmly pressed against the surface of the base film 2, and the air holes 2
