Clear deformation was observed in all 0 pieces even by visual inspection. Also,
In the drop test, damage was observed in 3 out of 10 pieces at the 20th to 28th drop.
本発明のエアゾール容器は、その容器本体が二重構造に
なっていて、且つ、内層が高ニトリル樹脂からなるので
、耐薬品性、ガスバリヤ−性などに優れ、エアゾール容
器として好適に使用し得る。Since the aerosol container of the present invention has a double-layered container body and an inner layer made of a high nitrile resin, it has excellent chemical resistance, gas barrier properties, etc., and can be suitably used as an aerosol container.
また、本発明のエアゾール容器は、外層が耐熱性、耐衝
撃性などに優れた合成樹脂からなるので、耐熱性、耐衝
撃性などに優れたエアゾール容器であり、更に、耐圧性
