/ Trangia Fuel Bottle
The Trangia fuel bottles are HDPE (high density polyethylene, aka 'fancy polythene'). Paraffin is often supplied in an HDPE bottle, e.g.
My only concern is that paraffin does tend to get everywhere. I was going to use the term 'creep', but that seems to have a specific meaning with paraffin at low temperatures. I mean that the oil tends to spread out if drips or runs occur at the spout. Meths, on the other hand, simply evaporates cleanly.
The design of the Trangia bottle closure is also unusual, in that the bottle has an internal thread, which is reinforced by an external, aluminium collar. It uses a silicone O-ring to form the seal.
Most simple bottles have an external thread, and a good cap has an internal thread to mate with this, but also should have a deep, internal, angled neck that mates with the smooth bottle opening inner face, forming a good seal.
I don't see a problem with using a Trangia fuel bottle to carry paraffin.
when using these bottles with meths there is always some 'leakage' when you have finished the job and have screwed the 'cap' back. ie there is still a small amount of meths in the system on the outside of the seal.
Therefore, given the smell and lack of evaporation of Papaffin I would not recommend Trangia bottles with the double spout cap. It will be a disaster!
My reply was mainly addressing the issue of chemical compatibility; it should be fine.
My comment about drips is pretty much the same as top cat's, only not quite as strongly worded; it will be an inconvenience, not a disaster...
