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.
A bottle cap is an inclined plane. I am not sure exactly why.
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.
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.
because they don't want you to spill it when you open it or because they are cheap. pick either reason.

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!
a bottle cap is on the top of a bottle, the size of the bottle is what determines the size of the cap. psypocalipse out.
The first modern bottle cap was a screw-on cap invented in 1856. There was also a recloseable wire-and-cap type of bottle cap invented in the same year, still used today on some high-end beers such as Grolsch. The modern "crown cap" bottle cap was invented in 1890, modernized to the "pilfer proof" cap in 1936, and twist-off bottle caps in 1966. Bottle caps are no longer manufactured today, as most people drink their beer straight from their high-speed internet connection. :)
