Abstract:
1. An applicator cap closed on a front side and opening on a rear side, covering an applying part provided in a front end of a barrel cylinder of an applicator, the applying part being inserted from the opening on the rear side and into the applicator cap, and detachably fitted on the barrel cylinder so as to be able to seal and keep a surrounding space of the applying part airtight, wherein an outer periphery of the cap has an annular indentation configuration formed in such a manner that an outside diameter of a middle part of the cap with respect to an axial direction of the cap is smaller than an outside diameter of a front end of the cap with respect to the axial direction and an outer periphery of the front end and an outer periphery of the middle part are continuously formed by way of a step having an angle, a slip stopper is formed, on an outer peripheral surface in a bottom of the middle part of the cap with respect to the axial direction, in a projected and indented configuration, a distal part of a projected portion in the projected and indented configuration is acute-angled, and the projected portion is annularly formed, a clip having a narrower width than the outside diameter of the middle part of the cap with respect to the axial direction is provided on an outer peripheral side of the cap, the barrel cylinder is provided at a front end of the barrel cylinder with a holder for holding the applying part, a diameter on a front side of the holder is smaller than a diameter on a rear side of the holder, and a sealing structure for keeping the surrounding space of the applying part airtight is formed at a corresponding position between an outer periphery of the smaller diameter part of the holder and an inner periphery of the cap, the sealing structure of the inner periphery of the cap is formed on an inner peripheral side of the middle part of the cap with respect to the axial direction, and the inner periphery of the cap is so formed that an inside diameter around the applying part is smaller than an inside diameter around the holder and a front end of the inner periphery of the cap is closed while an outer peripheral part in front of the middle part with respect to the axial direction is made greater toward the front, forming a hollowed bowl-like shape.
