A noise dampening member in or on the device inhibits noise and vibrations from the pump mechanism from transferring through the base and housing. The noise dampening member can be an elastomer that is coated on or adhered to the base. The noise dampening member can be molded in or on the base in a suitable location to dampen noise produced by the mechanical component. The noise dampening member can be between the base and the mechanical component or spaced from the mechanical component. The noise dampening member can be molded in a recessed area formed in the base and can have a top face that is recessed, aligned with or project from the top face of the base. ## Claims ### Claim 1 A delivery device, comprising: a housing;
