At this time, it is installed so that the opening of the outer cylinder is on the bottom and the collar portion of the auxiliary gripping member is caught in the hole. That is, in the state installed in the fixture, it is installed so that the distal end side of the outer cylinder protrudes upward from the hole of the fixture.

Abstract

La présente invention concerne un applicateur de tampon (1) qui comprend : un tube externe (2) ; un tube interne (3) qui, en étant inséré dans le tube externe, extrude l'absorbant (4) à l'intérieur du tube externe ; et un élément de préhension auxiliaire (10). Une ouverture est formée à une extrémité du tube externe, et une partie de préhension (7), que l'utilisateur saisit, est formée à l'autre extrémité du tube externe. L'élément de préhension auxiliaire (10) comprend une couverture (11) qui recouvre la surface circonférentielle externe de la partie de préhension de tube externe, et une bride (12) qui s'étend radialement vers l'extérieur depuis la surface circonférentielle externe (11a) de la couverture. Des saillies (5) qui font saillie radialement vers l'extérieur sont formées sur la surface circonférentielle externe de la partie de préhension. Des parties de verrouillage (13), qui engagent les saillies et restreignent le déplacement de l'élément de préhension auxiliaire par rapport au tube externe dans la direction d'insertion, sont formées sur la surface circonférentielle interne de la couverture.
