Apparatus for accommodating exchangeable containers and metering media

An apparatus for accommodating different exchangeable containers, each container having an actuatable spray pin for discharging contents of the container, the apparatus comprising:

• a body defining at least two separated and closable internal spaces, each internal space defining a longitudinal axis and adapted to receive one of the containers;
• and,
• a functional lid coupled to the body and closing one of the internal spaces, the functional lid including at least one spray-pin-receiving recess aligned with the longitudinal axis and positioned to receive and directly engage the spray pin when the one of the containers is received in the one of the internal spaces, the functional lid further including a channel having at least a portion aligned with the longitudinal axis and in direct fluid communication with the spray-pin-receiving recess for receiving and directing the contents of the container when the functional lid is actuated, and the functional lid further including an opening communicating with the channel and through which the contents of the container are expelled when the functional lid is actuated, wherein the functional lid is moveable with respect to the body to depress the spray pin and thereby expel the contents of the container through the channel and the opening.
