Microneedle-mounted seal-type fluid injection container

The present invention relates to a seal-type fluid injection container equipped with microneedles, which can inject a fluid for caring and treating skin or scalp while beating the skin or scalp. The present invention relates to a needle cover (20) in which a microneedle (25) is coupled to a coupling groove part (12) in the upper part of a container body (10) and to slit grooves (22) formed side by side in the left-right direction, and in which a fluid discharge hole (13) in the form of a long hole is formed in the bottom surface of the coupling groove part (12) in a direction intersecting the slit grooves (22) of the needle cover (20). According to the present invention, an air hole (14) is formed in the upper part of a container main body (10) for realizing air circulation while the fluid flows out, thereby not only being capable of appropriately, equally and smoothly supplying the fluid to a microneedle without a separate nozzle opening/closing structure, but also being capable of preventing fluid leakage a
