The plugging type dental liquid housing container, comprising,

• a container main body having a holding blade plate projected on an outer circumference face of a cylindrical liquid housing part which has an opening upper end and a closing bottom part, and
• a plug body having a sealing plug part at a lower end thereof, and a contacting blade plate projected on an outer circumference face of a plug main body which is provided starting from an upper end of the sealing plug part,
• wherein the container main body comprises,
• a flat face, which is rectangular with a center axis of the liquid housing part and is contacted with an end face being on the plug main body side of the lower face of the contacting blade plate, when the plug body is plugged, a slope face inclined to be raised in the predetermined direction from one end of the flat face,
• a stepped face fallen to another end of the flat face from a top point of the slope face, and
• an inner face taper part having an inner diameter gradually decreasing toward the bottom part side from at least the flat face, the slope face and the stepped face being formed at an end face of an opening end of the liquid housing part, the inner face taper part being formed on the opening part side of an inner face of the liquid housing part, and wherein
• the sealing plug part of the plug body comprises, a truncated conical shape part tapered toward the lower end, and
• plural annular projection ridge parts on the upper side of the truncated conical shape part, which are contacted with a portion on the bottom part side than the inner face taper part of the inner face of the liquid housing part of the container main body, and positioned at the inner face taper part of the liquid housing part when the plug body is rotated to move the end face of the contacting blade plate along the slope face of the end face of an opening end of the liquid housing part to the top point of this slope face.
