1. A method for using a medicinal fluid injection device including a housing having an opening in a side surface thereof, and an injection needle inside the opening, the method comprising:
positioning a cover body to the opening of the medicinal fluid injection device;
discharging an air in the injection needle to inside of the cover body as a priming operation comprising a movement of the medicinal fluid; and
separating the cover body from the medicinal fluid injection device,
wherein a cover part of the cover body is configured to bulge in a direction away from the housing due to the priming operation, and
wherein positioning the cover body is to define a closed space between the cover part and an auxiliary cover part which is positioned to the opening, and for the injection needle to penetrate through the auxiliary cover part.
