て指をけがするなどの欠点があった。Conventionally, solid and foamed polyvinyl chloride resins have been used for tear-off type caps such as lip caps and maxi caps. However, recently, di-2-ethylhexyl phthalate and di-octyl adipate, which have become the mainstream plasticizers contained in polyvinyl chloride resins, have become problematic in terms of toxicity. In addition, plasticizers used in polyvinyl chloride resin,
There are also safety issues with 7-talic acid plasticizers and citric acid ester plasticizers. Furthermore, if polyvinyl chloride compound lining caps containing plasticizers are used for beer, etc., there is a concern that the plasticizers will be extracted into the beer and impair the taste of the beer. When this happens, there is resistance when tearing, and the liner is difficult to cut, requiring force to open the cap, which can result in injury to one's fingers.
本発明はこれらの欠点を除去し、無害で引き裂き容易で
かつシール性にすぐれた引き裂き型キャップを提供する
ものである。The present invention eliminates these drawbacks and provides a tear-off cap that is harmless, easy to tear, and has excellent sealing properties.

シリコーンゴムに着目した。シリコーンゴムは価格が高
い欠点はあるが、その物性には非常に優れたものがある
。それは毒性の点では全く安のことはポリ塩化ビニル樹
脂に比し、量が少なくて所望のシール効果が得られる。The present invention focuses on silicone rubber, which has been conventionally used in pharmaceutical and food products. Although silicone rubber has the disadvantage of being expensive, it has very good physical properties. In terms of toxicity, it is quite cheap compared to polyvinyl chloride resin, and requires less amount to achieve the desired sealing effect.

る。In addition, since it is non-toxic, it can be used with any kind of contents with confidence.Furthermore, by using silicone rubber for tear-type caps, taking advantage of silicone rubber's weakness to tearing, which is said to be a drawback of silicone rubber, it can be used with polyvinyl chloride. The liner can be easily torn with less force than a tear-off cap made of resin, making it very easy to open.

。Moreover, it is easy to lay the silicone rubber on the tear-off die. This silicone rubber compound has thixotropic properties and can be easily cut from the nozzle that extrudes the foam compound during lining, allowing the liner to be lined accurately at the appropriate position on the inner surface of the tear-off type cap. It is very economical because the conventional lining machine for polyvinyl chloride resin can be used as is by selecting the fun pound. Note that the shape of the liner of the tear-off cap is not particularly limited as long as it is provided at a desired position depending on the intended use. Further, the silicone rubber may be of a thermosetting type or a room temperature curing type, and is not limited thereto either.

上記で得た引き裂き型リップキャップの性能Ｅ験を以下
の試験法により測定する。The performance E test of the tear-type lip cap obtained above is measured by the following test method.
１） 持続耐圧試験
規定の瓶を使用し、所定濃度の硫醗及び炭酸水素ナトリ
ウムを入れ、上記引き裂き型リップキャップを打栓密封
後、瓶内圧かびボリュームになる様調整する。常温にて
瓶内圧を安定させた後、ｇｔ’ｃ水槽中に７時間浸漬し
、再び常温に戻し、２ｔ１時間放置後、内圧を測定し、
ガスの漏れの有無を観る。1) Use a bottle specified for the sustained pressure test, add sulfur and sodium bicarbonate at the specified concentration, seal the bottle with the tear-off lip cap, and adjust the bottle internal pressure to the mold volume. After stabilizing the internal pressure of the bottle at room temperature, it was immersed in a GT'C water tank for 7 hours, returned to room temperature again, and left for 2t for 1 hour, then the internal pressure was measured.
Check for gas leaks.
２） 持続耐減圧試験
規定の瓶を使用し、沸騰水を満たし、上記引き裂き型キ
ャップを打栓密封後、常温にて２１時間放置し、減圧度
保持性を測定する。2) Continuous Decompression Resistance Test Using a bottle specified in the regulations, fill it with boiling water, seal it with the above-mentioned tear-off type cap, leave it at room temperature for 21 hours, and measure the degree of decompression retention.
結 果
上記のごとく、持続耐圧試験、會続耐減圧試験共に漏れ
はなかった。Results As mentioned above, there was no leakage in both the continuous pressure test and the continuous decompression test.
また引き裂きに対しては、ポリ塩化ビニルＩｉ脂と同じ
厚さ、量の場合３〜を分の／の力で裂は引き裂きを容易
にした。Regarding tearing, in the case of the same thickness and amount as polyvinyl chloride Ii fat, tearing was facilitated with a force of 3 to 1/2 minutes.
