1. A reservoir for a drug delivery device, the reservoir including a greatest depth, the reservoir comprising:
a first rigid body having a first face and an opposing second face, the first face having a first face first region and a first face second region surrounded by the first face first region, the first face second region being recessed a variable depth with respect to the first face first region;
a second body formed from flexible material, the second body having an attachment region welded onto the first face first region, the second body and the first face second region forming an interior volume of the reservoir, the interior volume holding a medicament volume;
an access port projecting outwardly from the first rigid body, the access port forming a continuous part of the first rigid body;
a channel extending from a first opening in an exterior face of the access port to a second opening into the interior volume, the channel forming a straight line segment from the first opening in the exterior face of the access port extending toward the interior volume, the channel defining a bore from the first opening;
a septum located in the bore; and
a cap partially covering the first opening and friction fit in the bore whereby the cap holds the septum in the bore.
 
13. A cassette for a drug delivery device, the cassette comprising:
a first body having a first face and an opposing second face, the first body formed of rigid plastic, the first face having a first face first region and a first face second region, the first face first region surrounding the first face second region, the first face first region being substantially planar, the first face second region being recessed a variable depth with respect to the first face first region;
a second body formed from flexible material, the second body having an attachment region welded onto the first face first region, the second body and the first face second region forming an interior volume of a reservoir, the interior volume of the reservoir being variable based on a displacement of the second body;
an access port raised from the first body, the access port being formed as a continuous part of the first body;
a channel extending from a first opening in an exterior face of the access port to a second opening into the interior volume, the channel forming a straight line segment from the first opening in the exterior face of the access port extending toward the interior volume, the channel defining a bore from the first opening;
a pierceable septum disposed in the bore, the pierceable septum, in an unpierced state, sealing a medicament volume within the reservoir, the medicament volume being pre-filled into the reservoir, the medicament volume filling the interior volume of the reservoir to a non-pressurized state; and
a cap partially covering the first opening and friction fit in the bore whereby the cap holds the septum in the bore.
