PROBLEM TO BE SOLVED: To obtain a container having an over-cap not being capable of being removed even when a user intends to remove the over-cap in a vertical direction, being capable of being easily removed by pulling up the over-cap while slightly rotating the over-cap and being capable of being fitted to the container by simply pressing the over-cap.SOLUTION: In a fitting cap constituted of a plug (1) covering a container mouth portion and a detachable over-cap (2) further covering the plug (1), the plug (1) consists of a plug top plate (12) covering an extraction port leading end of a container main body and a plug side wall (15), and the plug top plate (12) has a nozzle portion (11) extracting contents. The fitting cap includes: axes having predetermined inclined angles against an extraction direction on one wall between the plug side wall and an over-cap inner wall; a plurality of longitudinal ribs (16) having longitudinal ribs cross sections vertically cutting the axes and varying; and protrusions (23) on the other wall. The protrusions (23) are fitted among the longitudinal ribs (16) to be inserted therein, or the longitudinal ribs (16) are fitted among the protrusions (23) to be inserted therein.SELECTED DRAWING: Figure 1 |
