  • Patent number: 11737546
    Abstract: An applicator in which a through-hole in a plug cannot be distorted and therefore an air flow passage for a liquid application material can be secured, and liquid leakage from a core material impregnated with a liquid application material cannot be caused upon uncapping the applicator. The applicator includes: a body; an application member housed in the body; a storage section in which the liquid application material is stored; and a plug positioned on the rear end of the application member to penetrate and hold the application member into and in a through-hole that is bored in the plug, and can allow an rear-end-side tip part of the application member to be exposed on the storage section side, wherein the shape of the through-hole is formed in such a manner that the width of a gap between the through-hole and the application member penetrating in the through-hole can be adjusted.
