The discharge assembly includes a transmission member and a compression member that are connected to each other. The compression member is elastic. The coupling member includes a first end connected to the applicator assembly, and a second end detachably connected to the container assembly. The transmission member and the compression member are provided in the coupling member. The operable member is provided on a sidewall of the coupling member. A first valve is arranged between the first end of the discharge assembly and the applicator assembly. A second valve is arranged between the second end of the discharge assembly and the container assembly. Therefore, the material can be added to the applicator assembly through a one-handed operation of the user, and the use is very convenient. ## Claims ### Claim 1 A side-operated makeup pen, comprising an applicator assembly, a coupling member, an operable member, a discharge assembly, and a container assembly, wherein the discharge assembly comprises a transmission member and a compression member, wherein the transmission member and the compression member are connected to each other;
