Patent ID: 7886995

Claim:
A discharge mechanism of contents comprising: an operation member having a passage region for contents, an output hole in the passage region, and an output side space region having a first bottom surface part that is a sheath-shaped space region extending from the output hole part to a downstream side thereof; a sheath-shaped nozzle member mounted on said output side space region and having a second bottom surface part in which a discharge hole for said contents to an external space is formed; a core mounted between said operation member and said sheath-shaped nozzle member that includes a first contact part making contact with said first bottom surface part and a second contact part making contact with said second bottom surface part to produce a passage space for said contents between an outer peripheral surface of said core and an inner peripheral surface of said sheath-shaped nozzle member; a plurality of first downstream recessed passages outwardly extending from said output hole to said passage space provided on said first bottom surface part for generating an initial swirling flow of said contents in a first swirling direction from said output hole to said passage space; and a plurality of second downstream recessed passages inwardly extending from said passage space to said discharge hole provided on said second bottom surface part for generating a final swirling flow of said contents in same direction as said initial swirling flow from said passage space to said discharge hole.
