<p><P>PROBLEM TO BE SOLVED: To create a bottle form which ensures that a shrink film on it does not rupture in freezing and which is capable of absorbing an increase in volume due to the freezing, and to provide a synthetic resin bottle that can be safely preserved and used in freezing and which does not pose any problems in its outer appearance. <P>SOLUTION: In the bottle whose body portion 4 is wrapped with the shrink film 9, the circumferential length of the horizontal section of the body portion, across the range of the whole height of the portion wrapped with the shrink film, is made approximately equal to the circumferential length of the shrink film in its wrapped state, and with respect to the portion, out of the body portion, wrapped with the shrink film, the shape of the horizontal section across the range of a prescribed height is made out of round, thus the bottle is put to use by freezing a content liquid constituted mainly of water. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
