1. An aerosol-generating system comprising:
an aerosol-generating article, the aerosol-generating article comprising a single metered-dose of an aerosol-forming substrate, the metered-dose comprising an amount of the aerosol-forming substrate sufficient for generating an amount of aerosol for a single puff;
an airflow pathway arranged between an air inlet and an air outlet;
an aerosolisation chamber arranged at a location along the airflow pathway such that the airflow pathway passes through at least a portion of the aerosolisation chamber; and
a flow controller for selectively controlling the flow of air through the airflow pathway, the flow controller having an open configuration in which air can flow into and out of the aerosolisation chamber and a closed configuration in which air is substantially prevented from flowing into and out of the aerosolisation chamber;
wherein the aerosolisation chamber is configured to open to receive one aerosol-generating article at a time;
wherein the aerosolisation chamber is configured to close to contain the aerosol-generating article;
the aerosol-generating system further comprising:
a heating element arranged to heat the aerosolisation chamber when an aerosol-generating article is received within the aerosolisation chamber; and
a guard for preventing the aerosol-generating article from leaving the aerolisation chamber via the airflow pathway, the guard comprising a mesh or a plate having at least one hole formed therethrough for preventing the aerosol-generating article from leaving the aerosolisation chamber via the airflow pathway whilst still permitting air to flow through the airflow pathway, wherein the mesh or plate is arranged across at least a portion of the airflow pathway;
wherein the aerosol-generating system is configured to heat the aerosolisation chamber containing the aerosol-generating article when the flow controller is in the closed configuration.
