Abstract: A microneedle injection apparatus comprising a dual cover. The apparatus can include a housing having a base and a cavity; a microneedle array comprising a first side comprising a plurality of microneedles; and a microneedle array holder configured to hold a microneedle array and located in the housing. The microneedle array holder can be movable between a retracted position, and an extended position. The apparatus can further include a cover (113) configured to be positioned to cover the opening (115) in the base (112) of the housing. The cover can include (i) a first portion (140) configured to cover at least a portion of the base of the housing adjacent the opening, and (ii) a second portion (142) configured to be received in the cavity of the housing and further configured to cover the plurality of microneedles on the microneedle array when the microneedle array holder is in the retracted position.
