Why do plastic carbonated drink bottles have many "stubby" feet rather than a flat bottom?

Answer 1

Although,there is some thought applied from the answerers above,I tend to disgree on the grounds that "still" drinks dont have "feet".
I prefer to think that the design allows for structural integrity to the bottle containing highly expansive liquid.A flat base would become convex during expansion of the liquid and would be unable to stand.

Answer 2

The stubby feet serve this purpose: they minimize contact between the drink and the surface that it is sitting on. This minimizes thermal transfer, and keeps the drink colder for longer, since less of it is touching a warm table or coaster. This has an added benefit of not letting the drink go flat as quickly, since carbonation will dissipate faster from a warm beverage than from a cold one.

Answer 3

Actually it has more to do with the fact the plastic plugs are extruded in a press, and it is the molding process that causes it more than an issues of liquid contact or standing up, it is them mold itself that is responsible for the knobbly bottom.

Answer 4

ft might desire to be arched to stability the bodyweight between the heel and the forepart of the foot, This keeps stability and can provide the basically right option alignment to the backbone.Flat ft

Answer 5

its better for grip/balance a flat bottom can be knockeds over alot easier

Answer 6

its about pressure and the thickness of plastic used,.

Answer 7

hmm...good question
