       3 . The plastic bottle described in  claim 1  or  claim 2 , wherein at the bottom of the above-mentioned main body both ends in the width direction and both ends in the depth direction are rounded chamfered, and both the above-mentioned ends in the depth direction are round chamfered with a diameter that is smaller than that of the above-mentioned both ends in the width direction. 
   
   
       4 . The plastic bottle described in any one of the claims from  claim 1  to  claim 3 , wherein the above-mentioned main body has two first side walls that extend substantially in the width direction, and two second side walls that extend substantially in the depth direction, such that they are respectively positioned between the said two first side walls and moreover link these. 
   
   
       5 . The plastic bottle described in  claim 4 , wherein at least one of either the above-mentioned first side walls and the above-mentioned second side walls is curved outwards from the bottle. 
   
   
       6 . The plastic bottle described in  claim 4  or  claim 5 , wherein the corners between the above-mentioned first side walls and the above-mentioned second side walls are chamfered or rounded chamfered. 
   
   
       7 . The plastic bottle described in  claim 6 , wherein the lower part of the above-mentioned main body is chamfered or rounded chamfered at a greater value than the tipper part of the same. 
   
   
       8 . The plastic bottle described in  claim 6  or  claim 7 , wherein the distances between two corners located at opposed angles is formed such that the distance at the lower part of the above-mentioned main body is shorter than that at the upper part thereof. 
   
   
       9 . The plastic bottle described in any one of the claims from  claim 1  to  claim 8 , wherein the above-mentioned main part has vacuum absorption panels on at least two of the side walls. 
   
   
       10 . The plastic bottle described in  claim 9 , wherein at least two of the above-mentioned side walls are side walls that extend substantially in the width direction of the above-mentioned main body. 
   
   
       11 . The plastic bottle described in any one of the claims from  claim 1  to  claim 10 , wherein concave ribs are formed along the circumferential direction on the above-mentioned main body. 
   
   
       12 . The plastic bottle described in any one of the claims from  claim 1  to  claim 11 , wherein when the transverse sectional area of the above-mentioned mouth is set at A and the transverse sectional area of the above-mentioned main body is set at S, 4.0≦S/A≦13.0. 
   
   
       13 . The plastic bottle described in any one of the claims from  claim 1  to  claim 12 , wherein the bottle capacity is at least 300 ml and no greater than 800 ml, or the bottle height is at least 140 mm and no greater than 220 mm. 
   
   
       14 . The plastic bottle described in any one of the claims from  claim 1  to  claim 13 , wherein the said plastic bottle is formed by stretch molding by the cold parison method with a parison whose section is a perfect circle.
