DRINKABLE WATER BOTTLE MADE OF PLASTIC

摘要

The drink water bottle of good impact resistance and pressure resistance has five legs each at every 72 degree on the bottom part. An angle of the rib(42) on the bottom is larger than an angle of the leg(40). A groove(44) is projected to inside of the bottle in the center of the bottom of the rib(42) and the leg(40), and a diameter of the inner groove(44-2) is larger than that of the outer groove(44-1). Apexes(P1) of the rib(42) and the leg(40) are formed on the outer groove(44-1) and the inner groove(44-2), respectively. The bottom(40-1) of the leg(40) is formed in slant and straightly to the normal line of the groove(44).
