<P>PROBLEM TO BE SOLVED: To provide a liquid storing tool capable of generating large liquid suction force by actuating a pump device and having good use feeling. <P>SOLUTION: An engine oil storing tool 1 comprises a bottle 5 and a pump device 7 fixed to a mouth part 3 of the bottle 5. A piston rod 13 of the pump device 7 is formed in a hollow shape, and the inside of the piston rod 13 is communicated with a cap-side space 45 of a cylinder 9. A base of a suction pipe 17 is connected to an upper end of the piston rod 13. A discharge tube 19 is attached to a lower end of the cylinder 9. A check valve preventing a liquid reverse flow is structured in the piston rod 13. A check valve preventing air inflow from the inside of the bottle 5 is structured at the discharge tube 19. <P>COPYRIGHT: (C)2013,JPO&INPIT |
