Pinhole gas / gas bottle

Pinhole gas

Butane gas is convenience.but,it might regard as a double-edged sword.Pinhole part of yellow is made of elastic material,unlike the rest of part.This pinhole lets you recognize which is using before and after.In addition, in case of explosion when atmospheric pressure becomes higher with rising temperature,pinhole would pop out so that warn you of the dangers of explosion.When the pressure in gas container goes lower, the pinhole also goes down toward the bottom.So there is an empty part after pinhole goes down,this gap not only show you the availability of the gas before using it,but also give you space to make piercing a hole after using.
