<P>PROBLEM TO BE SOLVED: To solve the following problems of a conventional bottle container: it is difficult to use up all the content due to flat or convex inside bottom surface, opaque body, or indistinguishable nozzle direction; a viscous pump bottle container gradually sags in the middle, and air is sucked, thereby becoming difficult to empty it; and it is difficult to distinguish the direction of a nozzle of a spray bottle container which is used generally aslant and only the air and gas come out. <P>SOLUTION: In order to use up all the content, the inside bottom surface of the bottle container has a concave surface structure in which the center is concave so as to gather the content. Accordingly, the content is gathered in the center by dead weight. The spray bottle container which is used generally aslant has the concave surface structure, thereby emptying the container even when it is used aslant to some extent. <P>COPYRIGHT: (C)2012,JPO&INPIT |
