Disinfectant caps and packaging for use with a medical device (e.g., connector, luer access device, etc.) are disclosed herein. The disinfectant caps apply the antiseptic fluid (e.g., disinfectant) directly onto the surface of the medical device. The disinfectant cap for disinfecting a surface of a medical device comprises a cap body having a bottom wall and a sidewall extending therefrom, the sidewall defining a top opening, antiseptic fluid contained within the cap body, and a deformable top wall connected to the cap body, the top wall movable from a first position sealing the antiseptic fluid within the cap body to a second position releasing the antiseptic fluid from the cap body.
