  • the retaining protrusion will engage with the retaining protrusion to secure the first housing portion 110 to the second housing portion 120.
  • the first housing portion 110 is considered to be engages with the second housing portion 120. This action compresses the sealing material which may flow across the interface 130 between the first housing portion 110 and the second housing portion 120 to form a seal. Any excess sealing material is collected in the first 114 and second 124 reservoirs to prevent leakage out of the aerosol-generating device 100.
