Abstract

Abstract A plastic beverage container is formed from a tubular blank and has a lower portion formed in a bottle-like shape and an upper portion which includes a gradually diametrically reduced bellows tube. The upper portion further comprises a mouth tube with a smaller diameter than the bellows tube with the upper portion of the mouth tube forming a small tube with a smaller diameter than the mouth tube. The upper portion of the small tube forms a fine tube with a smaller diameter than the small tube with a thin walled junction formed between the small tube and the mouth tube. The small tube is provided with a pair of outwardly extending twist vanes to permit the tube to be broken at the thin walled junction for consumption of the beverage.
