If the cover of a reagent bottle is placed on a table with the bottom down, it can pick up material from the table which would contaminate the contents of the reagent bottle after the cap is put back on the bottle.
The reagent bottle is not used for dropping, having only a common stopper.
It is a heavy glass bottle (unlikely to break or react with the reagent chemicals) used to store moderate amounts of laboratory chemicals (reagents)
used as a container where you put chemicals that can't be thrown in the sink.

This is to prevent contamination of the remaining reagent in the bottle.
So you don't get water, dirt or other contaminants in the reagent bottle. The reagent bottle should contain chemicals that are as pure as possible. If each person put a dirty spatula in the bottle, the reagent bottle would very quickly accumulate all kinds of junk, ruining the chemicals inside or causing hazardous chemical reactions.
A Reagent Bottle.
Your question supplies its own answer, though you may need to ensure the bottle's material will withstand the intended reagent.
Reagent bottles are containers made of glass or plastic, and are closed by special caps or stoppers, and are intended to contain chemicals in liquid or powder form for laboratories and stored in cabinets or on shelves.

used to utilize chemicals
To remove the fine solid powder from the reagent bottle used clean, dry spatula and transferred to a clean, dry watch glass or poured from a bottle by slightly tipping and then rotating the bottle.
