チャイルドレジスタントキャップ

Took me a solid minute to figure out the push-and-turn motion, but that's exactly what I wanted for the medicine bottles. The 45mm fit snugly on the 250cc round bottles, no wobble or leaks.

Finally, a cap that actually requires adult-level coordination to open—my toddler hasn't cracked it once. The 45mm size fits our round pharmacy bottles perfectly, and the mechanism feels sturdy without being frustrating for me.

The push-down-and-turn mechanism is really stiff out of the package, which gave me confidence it’ll actually keep curious little hands out. After a few tries it loosened up slightly but still requires two coordinated movements to open.
