<P>PROBLEM TO BE SOLVED: To propose a container with a pump which is capable of stably dispensing its contents without causing air intrusion. <P>SOLUTION: The container with a pump includes: a body 1 defining a filling space for contents; a pump 4 held so as to be suspended from the top of the filling space M through a mouth 1a in the body 1; a nozzle head 5 that actuates the pump 4 such that the contents in the filling space M is jetted outside by its being sucked, pressurized, and compressed; and an inner plate 11 defining a bottom wall for the filling space M and slid upward in the filling space as the filled contents decreases in quantity. In the container with a pump, the suction opening S of the pump 4 is provided with a valve 4d that opens only when the contents are sucked, thus preventing air remaining in the cylinder 4a from being shifted into the contents. <P>COPYRIGHT: (C)2010,JPO&INPIT |
