Help with Chinese box inscription and use

This Chinese box is being offered through an online auction. I'm intrigued by it, and would like to know if anyone knows what the inscription reads and also what might be the use of this box. Is it a trinket box? Additionally, do you have any guess as to its age. It's being sold as part of an estate.

 

looks like a pill box

 

What's it lined with? The writing on top doesn't look like modern Chinese.

 

The auction is some distance away, so I've not been able to personally handle it. I'm relying only on pictures provided, which don't include a picture of the inside beyond the one given.

 

Looks like copper and brass to me.

 

Same thoughts from me..copper & brass.

 

possibly an aide-memoire for non-chinese scripts ? important "words" in local and/or Korean caligraphies ?

 

maybe...they put remembering pills inside ???

 

Mark on the base is ?昌隆製 '?Chianlong made', the 'Made in China' stamp is most likely early post war, but may be inter-war at a push. Script on the top seems to be a mix of archaic Chinese and modern Chinese - so perhaps just made up - hardly anyone in China actually reads or understands archaic script outside university scholars. You sometimes find items where the maker just used old language for fun without even knowing what it meant, just because it looks cool. Same concept as someone in the UK using Celtic runes for example.
