Applicator

摘要

An applicator comprising a transmission member, a housing guiding a reciprocation of the transmission member, and a cap covering the housing. The transmission member is provided with a stopper extending in a direction orthogonal to an axial direction thereof. An upper end of the housing is formed with a projection sliding the stopper. The inside of the cap is formed with a lead part. The stopper is slid by the lead part to an end part of the projection when the cap is pushed and thereafter disengages from the projection when the cap is further pushed, so that the transmission member transmits the biasing force of an elastic member to a microneedle. This enables the microneedle to be applied to skin.

1. An applicator for applying a microneedle to skin, the applicator comprising:
a transmission member for transmitting a biasing force of an elastic member to the microneedle; a housing containing at least a part of the transmission member and guiding a reciprocation of the transmission member; and a cap disposed so as to cover the housing and adapted to impart the biasing force to the elastic member by being pressed toward the transmission member; wherein the transmission member is provided with a stopper extending in a direction orthogonal to an axial direction of the transmission member; wherein one end of the housing adapted to mount the stopper is formed with a projection guiding the stopper along one circumferential direction; wherein an inside of the cap is formed with a lead part adapted to come into contact with the stopper when the cap is pushed; and wherein the stopper is slid by the lead part to an end part of the projection when the cap is pushed toward the transmission member and thereafter disengages from the projection when the cap is further pushed toward the transmission member, so that the transmission member transmits the biasing force to the microneedle.
