An interesting proposal. I'm not a fan of puzzle caches, but they're clearly marked on the map and easy to avoid.

If the cache description (or logs) don't mention the type of container, how would one avoid finding that type of container?

Exactly.

I don't hate anything

 

I don't see any hate going on either.  I think that in general, geocachers prefer a larger container that is weather resistant or even water proof, but to claim that geocacher *hate* containers that are not ideal is a gross exaggeration.

This is my alternative to a film canister:

The thread of a beverage bottle is sawn off. I opted for a standard returnable bottle in Germany (Perlenflasche) because they are more robust than disposable ones . The cut surface is then ground off.

The thread is then placed on aluminum foil and four magnets are placed in it. I use 8mm diameter and 2mm thick ones. 9mm diameter also fit and you can also use thicker magnets if necessary. My first attempts were 2 magnets 10 mm in diameter and 2 mm thick. Also works, but was too weak for me.

The thread is then filled with two-component adhesive until the magnets are just covered. The aluminum foil is easy to peel off and if there are leftovers, they don't bother either. From today's experience, I would prefer to leave it on because it is an additional protection for the magnets. If the cache is placed on a rough surface and the protective layer of the magnet is damaged, it will start to corrode.

The cache is waterproof like a petling and has an inside diameter of 21mm and a depth of 17mm

The reason why I came up with this solution is that it looks like a rotary knob or a valve and, on corresponding technical systems, looks like it belongs to them. I painted one red and attached it to the side wall of an extinguishing system in a parking garage. It is clearly visible to the public and has survived well for 5 years so far.

I found one like those yesterday.

I made one of these; it's been deployed for years.

 

It's embedded in a six-inch block of 2x4, screwed to what had been a utility panel on a pre-existing desolate pole.

 

The cap is the original Coca-Cola cap. "Hmmm," she thought as she stood in the middle of the field. "Something looks out of place."
