<p><P>PROBLEM TO BE SOLVED: To solve the problem that the purpose is not sufficiently achieved owing to the overflowing of a liquid to be poured into a glass or a container because the inflow of a pressure allowing the liquid to exit and that of air in an amount corresponding to a liquid amount flowing out try to enter an existing pet bottle cause such an alternately breathing state when pouring the liquid from the pet bottle and prevent the liquid in the pet bottle from stably pouring out. <P>SOLUTION: An air hole C is formed at the upper part of the main body of the pet bottle as shown in Fig.1, so that the trouble in pouring the liquid which is shown when unsealing begins is avoided, and the pet bottle is safely used. The liquid in the pet bottle does not flow backward through the air hole even when the pet bottle is completely turned upside down, and the liquid in the pet bottle is quickly poured for a relatively short time. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
