The invention discloses a novel sealed packaging container, which comprises a container cover and an open container body. A first inner matching groove, a second inner matching groove, a first outer matching groove and a second outer matching groove of the rotating structure are correspondingly arranged on the edge of the container cover and the mouth of the container body; the second inner matching groove is nested in the first inner matching groove, and the first outer matching groove is nested in the second outer matching groove; and an anti-tripping structure is further disposed on the novel sealed packaging container. At least one pair of corresponding groove walls of the first inner and outer matching grooves and the second inner and outer matching grooves are tapered and fitted to each other. The inner groove walls of the first inner matching groove and the second inner matching groove and/or the outer groove walls of the first inner matching groove and the second inner matchinggroove are in line contact with each other in an elastic ejecting-holding manner. Two indentations that are easy to tear are extended downward from the upper end portion on the outer groove wall of the second outer matching groove, the portion between the two indentations forms an anti-counterfeit strip, the depth of the two indentations is slightly smaller than the thickness of the outer groovewall of the second outer matching groove. According to the packaging container of the invention, the anti-deformation ability is high, the anti-tripping structure is relatively stable, and the sealingperformance is good.
