Summary for Patent: 8,931,476
Abstract: An inhaler, such as a breath-actuated metered-dose inhaler, for delivering medicament to a patient. The inhaler includes a housing for holding the medicament and having an air inlet and a medicament delivery port which together define an air flow path into which the medicament is dispensed. The air inlet includes an array of elongate apertures formed in the housing, the long sides of adjacent apertures facing each other. Each aperture is provided with a respective different opening in an outer surface of the housing. The opening of each aperture extends in two different planes such that, if at least a part of the opening is covered in one of the two different planes during inhalation by the patient, a void space is created between the cover and the aperture so as to provide an air flow path through the void space to the at least one aperture.
