description The present invention relates to an inhaler housing. The inhaler housing being arranged to contain a pressurised canister for sliding motion within a tubular body, the inhaler housing having a valve stem block for connection to a valve stem of a pressurised canister, the valve stem block having a top surface, the tubular body having at least two mutually opposed guide ribs for guiding canister position. The guide ribs have substantially straight guide edges extending substantially parallel to and spaced from one another. Each straight guide edge has an upper corner where the straight guide edge meets a further surface of the rib leading outwardly towards an upper rib section near an inner wall of the tubular body. At least one of the ribs has its straight guide edge's upper corner positioned a distance D2 in a direction parallel to an axis of the valve stem block along away from the top surface of the valve stem block, a distance between the straight guide edges of the ribs perpendicular to the axis being ID2, and in which the ratio D2/ID2 is less than 0.8.
