a first latch moveable between a latched configuration wherein the first latch secures the first and second housing components in the closed configuration and an unlatched configuration wherein the first and second housing components are moveable to the open configuration;
a cap movably connected to one of the first and second housing component, wherein the cap is moveable between a closed position, wherein the cap engages the other of the first and second housing components and maintains the first and second housing components in the closed configuration, and an open position, wherein the first and second housing components are capable of being pivoted to the open configuration; and
a second latch moveable between a latched configuration wherein the second latch secures the cap to the other of the first and second housing components in the closed position and an unlatched configuration wherein the cap is moveable to the open position, and wherein the first latch is moveable from the latched configuration to the unlatched configuration only when the second latch is in the unlatched configuration.
11. The holding chamber of claim 10 wherein at least one or both of the first and second housing components comprises an engagement member disposed in the interior space, wherein the engagement member is adapted to engage a medicament delivery device disposed in the interior space, and wherein the interior space is dimensioned to receive the medicament delivery device when the first and second housing components are in the closed configuration.
12. The holding chamber of claim 11 wherein the engagement member comprises a first rib disposed on the first housing component, wherein the first rib is shaped and dimensioned to engage the medicament delivery device.
13. The holding chamber of claim 12 further comprising a second engagement member comprising a second rib disposed on the second housing component, wherein the second rib is shaped and dimensioned to engage the medicament delivery device.
14. The holding chamber of claim 10 further comprising a biasing member biasing the cap to the open position and maintaining the cap in the open position when the second latch is in the unlatched configuration.
15. A holding chamber configured to enclose and carry a pressurized metered dose inhaler, the holding chamber comprising:
a first housing component comprising a user interface having an outlet opening; and
a second housing component having an inlet opening spaced apart from the outlet opening of the first housing component, wherein the inlet opening comprises a sealable backpiece configured to receive a mouthpiece of the pressurized metered dose inhaler, wherein the first housing component is pivotally connected to the second housing component about a pivot axis, wherein the first and second housing components are pivotable relative to each other about the pivot axis between a closed configuration and an open configuration;
