PRESSURED THERMOPLASTIC BEVERAGE CONTAINING BOTTLE WITH FINGER GRIPPING FORMATIONS

摘要

A thermoplastic bottle having a generally cylindrical body, in turn having an upper portion, a lower portion, and opposite sides joining at a diametric plane. A plurality of adjacent finger recesses extend about one of the opposite sides in the lower portion of the body, and a thumb depression is provided in the lower portion on the other of the opposite sides. A continuous circumferential indentation is formed in the cylindrical body between the upper portion and the lower portion to decouple pre ssure response of the upper and lower portions and minimize lean transfer to the upper portion resulting from expansion of the lower portion on the one of the opposite sides. The bottle is also formed with at least one vertical reinforcing indentation, preferably at least one set of three such vertical reinforcing indentations in each of the finger grooves, a nd at least one, preferably three spaced vertical reinforcing indentations in the thumb depr ession. The bottle has a bottom closure base having an odd number of at least five proje cting feet, one of the feet being aligned vertically with the thumb depression so that at least three of the five feet remain in a common plane during vertical stretching to as sure a stable base for maintaining the bottle in upright posture.
