A bottle cap is an inclined plane.
I am not sure exactly why.
A screw has external threads, so methinks the screw-top BOTTLE is really the screw, and the cap a mere receptacle. Yes. And a screw is really a modified wedge or incline.
If you mean 'Screw Thread' I will give examples, but first understand that the word screw is a process. It is something you can do. We often say 'Screw these pieces together'. Now some examples :- Top of a toothpaste tube with a screw on lid. top of a jar of food with a screw on lid . A screw thread inside a water tap handle. Most common of all of course is a wood screw, and a metal thread screw or bolt.. Also the screw thread on the cap of a bottle of soft drink.
The sphere forms a circle in the plane. There are two bits of sphere which are spherical caps with a circular base.
Then you would have an upside down liter bottle. Hopefully the cap is on because then you would just have a mess...good thing it's just water
Maybe a water bottle cap, a paperclip, a small eraser, a small leaf, and a grape.
some examples of screws in a house-a bulb holder , a jar lid or a bottle cap.

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 screw on bottle cap was introduced in the early 1960s, eliminating the need to use bottle openers, first in sodas, then a little later, bottled beer and now, good grief, wine!!! However, there are some (bless them) companies that refuse to bottle their beer or wine using these convenient but annoying screw on lids!
