Abstract
Cartridges are configurable between a closed state and an open state. The cartridges include a cartridge body and a reservoir disposed in the cartridge body. The cartridge body has an outer locking element, and the reservoir has a rotational locking element. In the closed state, the outer locking element engages the rotational locking element such that the reservoir cannot be rotated out of a first rotational position relative to the cartridge body in which a fluid outlet of the reservoir is not in fluid communication with a fluid outlet of the cartridge body. In the open state, the outer locking element of the cartridge body does not engage the rotational locking element of the reservoir, and the reservoir is in a second rotational position relative to the cartridge body such that the fluid outlet of the reservoir is in fluid communication with the fluid outlet of the cartridge body.
