った。However, a spout cap formed of a relatively soft synthetic resin such as a low-density polyethylene resin has a low heat resistance, and therefore has a low heat resistance of, for example, 85%.
When the content liquid is heated and filled at ~ 90 ° and sealed with the spout cap, the spout cap is heated by the pre-cooled content liquid and thermally shrinks and deforms, and the sealing property is reduced and the bottle is sealed. There was a problem that the assembling strength was reduced.
【０００６】また、全体を一体成形するものであるか

ことになる。[Function] Assembling the spout cap to the mouthpiece of the bottle
This is achieved by forcibly pushing the inner cylinder into the mouthpiece from above while inverting the seal cylinder piece upward and outward with the reinforcing cylinder fitted to the outer periphery of the inner cylinder of the cap body. In this assembled state, the sealing cylinder piece is densely fitted between the reinforcing cylinder made of a relatively hard synthetic resin and the mouthpiece.
The outer peripheral surface of the inverted seal cylinder piece is pressed against the inner peripheral surface of the mouthpiece.

A substantially central portion of the cylindrical wall is connected to the top plate 5 and a part of the bottom wall is provided. On the upper surface, a pull ring 1 is formed by engraving a breaking groove 8.
0 is integrally formed to form an excision wall 9.
【００１６】また、内筒３外周面上端の頂板５部分に

との連続部に係止して、上記嵌着状態が維持される。Next, the reinforcing cylinder 12 having an inner diameter equal to the outer diameter of the inner cylinder 3 of the cap body 2 and fitted to the outer peripheral surface of the inner cylinder 3 is made of a relatively hard synthetic resin material. Upper end is concave groove 6
And the lower end thereof is engaged with a continuous portion between the lower end of the inner cylinder 3 and the upper end of the seal cylinder piece 11, so that the above-mentioned fitted state is maintained.

である。When the dispensing cap 1 is to be fitted from above into the mouthpiece 14 of the bottle 13 with the reinforcing cylinder 12 fitted on the cap body 2, first, the upper end of the mouthpiece 14 is enlarged in diameter. When the sealing cylinder piece 11 is brought into contact with the sealing cylinder piece 11 and forcibly pushed from above, the sealing cylinder piece 11 is turned upward and outward, and is tightly fitted between the reinforcing cylinder body 12 and the mouthpiece 3. It becomes.

保されるのである。Therefore, even if the dispensing cap 1 is heated by heating and filling the bottle 13 with the liquid, the reinforcing cylinder 12
Does not generate thermal shrinkage deformation, the pressurization between the outer peripheral surface of the inverted seal cylinder piece 11 and the inner peripheral surface of the mouthpiece 14 is maintained,
The sealing performance of the bottle 14 of the bottle 13 with the dispensing cap 1 is ensured.
【００２０】補強筒体１２は、キャップ本体２とは別体
に成形されるので、成形時の型抜きに規制されることは
なく、或る程度自由な形状を選択できる。Since the reinforcing cylindrical body 12 is formed separately from the cap body 2, the reinforcing cylindrical body 12 is not restricted by die-cutting at the time of forming, and can have any shape.

われることはない。According to the pouring cap of the present invention, when assembled to the bottle mouth cylinder, the seal cylinder is integrally connected to the lower end of the inner cylinder of the cap body formed of a relatively soft synthetic resin. Since the piece is located between the reinforcing cylinder and the mouthpiece molded of a relatively hard synthetic resin, the reinforcing cylinder is not deformed even if the pouring cap is deformed due to heat shrinkage or the like. Therefore, the inverted outer peripheral surface of the seal cylinder piece is always pressed against the inner peripheral surface of the mouthpiece, so that the sealing performance is not impaired.
