small bottle

[Diver Dave]

Here's a bottle I just found today. Its approx 3 3/4 " tall with a cap that is mostly rotted away. It is marked around the neck with the date Feb. 14 1922, and MCH. PAT'D. Can anyone tell me what it is? Thanks!

Here's a better picture of the MCH PAT'D marking. Is this possibly an Ink bottle?
Thanks
