PROBLEM TO BE SOLVED: To provide an inside plug that facilitates insertion of an absorbent wick, and to provide a vaporization device.SOLUTION: A funnel part 71 is provided on an inside plug 43 mounted on an opening 42 of a container 11. The funnel part 71 includes: a large-diameter cylindrical part 72 that extends downward from a top surface 53 a tapered part 73 that inclines inward as extending downward from the lower edge of the large-diameter cylindrical part 72 and a small-diameter cylindrical part 74 that extends downward from the lower edge of the tapered part 73. The small-diameter cylindrical part 74 has a linear shape that extends in the up-down direction, and an insertion hole 91 for guiding an absorbent wick in the vertical direction is provided on the inner side of the small-diameter cylindrical part 74. A guide part 101 is provided on the lower portion of the funnel part 71, and extends downward from the lower front edge of the small-diameter cylindrical part 74. The guide part 101 is inclined toward the back surface side as extending downward, and guides the absorbent wick 44 inserted into the insertion hole 91 in an oblique direction.COPYRIGHT: (C)2015,JPO&INPIT【課題】吸上芯の挿入を容易とする中栓及び揮散装置を提供する。【解決手段】容器体11の口部42に装着される中栓43に漏斗部71を設け、漏斗部71を天面53より下方へ延出した大径円筒部72と、大径円筒部72の下縁より下方へ向かうに従って内側へ傾斜したテーパー部73と、テーパー部73の下縁より下方へ向けて延出した小径円筒部74で構成する。小径円筒部74を上下方向に延在する直線状に形成し、小径筒部74の内側に吸上芯を垂直方向に案内する挿通穴91を設ける。漏斗部71の下部にガイド部101を設け、ガイド部101は小径円筒部74の前方側の下縁より下方へ向けて延出する。ガイド部101を下方へ向かうに従って背面側へ向けて傾斜し、挿通穴91を挿通した吸上芯44を斜め方向に案内する。【選択図】図4
