<P>PROBLEM TO BE SOLVED: To prevent any liquid leakage from a discharge port without increasing the number of components while ensuring the quality of a content. <P>SOLUTION: A discharging container includes a container body 4 having an inner container 2 rich in flexibility for storing a content, and an outer container 3 that is elastically deformable, and a discharge cap 6 attached to a mouth 4a of the container body 4 with a discharge port 5 being formed therein. An intake hole 8c from which outside air is sucked is formed between the outer container 3 and the inner container 2. The discharge cap 6 includes an outside air introducing hole 11d for communicating the outer side with the intake hole 8c, an air valve 12c for changing the communication and the interception between the intake hole 8c and the outside air introducing hole 11d, a communication hole 10g for communicating the discharge port 5 with the inside of the inner container 2, a valve member 12b for changing the communication and the interception between the discharge port 5 and the communication hole 10g, and an discharge film 20 that is elastically deformable to close the discharge port 5. A slit 20a is formed in the discharge film 20, and when the discharge film 20 is elastically deformed as the internal pressure in the inner container 2 is increased, the slit 20a is expanded to open the discharge port 5. <P>COPYRIGHT: (C)2013,JPO&INPIT |
