た。However, since a gas barrier property is required for a sealing film, a laminated film using an aluminum foil as a barrier layer has been conventionally used. However, in this sealing film, in the disposal treatment after use, the residue of the aluminum foil remains at the time of incineration, and it is difficult to reuse the sealing film. Accordingly, recently, as a sealing film, as a substitute for a conventional laminated film using an aluminum foil as a barrier layer, a ceramic vapor-deposited film in which silicon oxide or the like is vapor-deposited on a polyethylene terephthalate film has tended to be used. However, the sealing film using this ceramic vapor deposition film has elongation unlike the sealing film using the conventional aluminum foil,
In the conventional opening-blade built-in spout provided with a plurality of opening blades having the same blade height or a plurality of opening blades sequentially having a small difference to the left and right around the opening blade having a high blade height, sealing is performed. The sealing film may not be easily broken by the opening blade due to the elongation of the film, and the commercial value of the product may be impaired.

The invention is characterized in that the plug body comprises a cap body and a cap which are externally protruded from a discharge hole of a liquid paper container sealed with a sealing film and movably incorporates an opening tubular body. At the time of removing the cap screwed into the cap, the cap is rotated to move the opening cylinder downward to break the sealing film. A plurality of triangular opening blades vertically connected to the lower end surface and vertically attached to the lower end surface, and a combination of a high blade height opening blade and a low blade height opening blade is provided. It is a stopper.

A plug comprising a plug body and a cap, wherein the cap is rotated to move the unsealing cylinder downward to break the sealing film when removing the cap screwed to the plug body. In the above, a plurality of triangular opening blades vertically connected to the lower end surface of the tubular body of the opening tubular body and connected vertically are mixed with a high blade-height opening blade and a low blade-height opening blade. A plug with a built-in opening blade, characterized in that it is provided with an opening.

た。According to the conventional opening plug with a built-in opening blade, the sealing film is first cut into a broken circular shape by a plurality of triangular opening blades provided at the lower end of the opening cylindrical body which descends at the time of opening. In the case of a sealing film using a ceramic vapor-deposited film, since the film has a large elongation, after being cut by the opening blade, it is further pulled by the valley between the opening blade and the lower end surface of the opening cylindrical body, The film could break, requiring a large force to break the sealing film.

要としない。On the other hand, in the plug with a built-in opening blade according to the present invention, first, a sealing film is formed by a plurality of triangular high-opening blades provided at the lower end of the opening cylindrical body which descends at the time of opening. After being cut into a broken circular shape, the sealing film extending along the lowering of the opening blade is then cut by an opening blade having a further lower blade height, which is used as a trigger to break the film. For this reason, even with a sealing film using a ceramic vapor deposition film having a large elongation, no force is required to break the sealing film as compared with a conventional opening blade of a plug with a built-in opening blade.
