SPUIT

摘要

The present invention relates to a spuit comprising: a cap unit coupled with the top end of a container and having an assembling hole formed in the top end thereof; a flexible pumping unit having a flange formed in the bottom end thereof, having an assembling groove formed in the top of the flange to be inserted in an assembling hole, having a hanging projection formed in the top end of the assembling groove, and having a pumping hole formed therein to be pumped by being elastically restored after shrinking by pressure, wherein the pumping hole is downwardly opened; and a pipe-shaped spuit pipe having a coupling projection formed on the top end outer circumferential surface to be inserted in a coupling groove formed in an inner circumferential surface disposed in the flange top of the pumping unit. More specifically, multiple first projections and first grooves are formed in the outer circumferential surface of the assembling groove contacting the inner circumferential surface of the assembling hole. Accordingly, when the assembling hole of the cap unit and the assembling groove of the pumping unit are assembled, only the first projections of the assembling groove contact the inner circumferential surface of the assembling hole. Consequently, when the coupling projections of the spuit pipe are inserted in the bottom end of the downwardly-opened pumping unit, gaps between the first projections or the first grooves are enlarged or expanded, and the coupling projection of the spuit pipe is actively inserted, so that the assembling properties of the spuit pipe can be improved.
