<p><P>PROBLEM TO BE SOLVED: To provide a container which is integrally formed with an opening narrower than the inner diameter of a body portion and is capable of supporting itself on a horizontal surface, wherein almost the entire amount of liquid contents can easily be taken out, and the container can be implemented at low cost. <P>SOLUTION: The opening (3) narrower than the inner diameter of the body portion (2) is integrally formed with the upper end of the body portion (2) having the shape of a tube with a bottom. A horizontal ground-contact portion (7) which can stably be placed on the horizontal surface is formed on the lower surface of a bottom part (6) of the lower end of the body portion (2). A recessed portion (8), which is deeper than the peripheral part is formed at the center part of the inner surface of the bottom part (6). The recessed portion becomes gradually deeper toward the center part, and the part between the center part and the peripheral part is formed on a curved surface projecting toward the inside of the body portion (2). A thick-walled portion (9) having a thickness thicker along the peripheral part than in the center part is formed on the bottom part (6). An annular groove portion (10) is formed on the outer peripheral surface of the thick portion (9). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
