  • Patent number: 11766110
    Abstract: An applicator which comprises an application body arranged inside the front part of a barrel cylinder supplying the application body with the application liquid stored in a storage portion in the barrel cylinder, and is configured such that: a full coupling portion and a temporary coupling portion are formed on each of a front barrel and the barrel cylinder; the front barrel and the barrel cylinder each have an anti-rotation rib; the anti-rotation ribs are not engaged with each other in the initial coupled state before the temporary coupled state in which the temporary coupling portions of the barrel cylinder and the front barrel are engaged with each other; and, the anti-rotation ribs become engaged with each other in the fully coupled state in which the full coupling portions are engaged with each other.
