I guess photoworks is a private user only site. Strange to be photo-sharing...

I have a plastic bottle that once held Lipton's green tea.

The cap has similar threads.
I'm wondering what the reason for these strange threads?

Can't see the photo without signing up.

So it had a break-off tamper indicator ring at the bottom of the cap?

Maybe to make it easier to push the cap onto the bottle.
