Abstract:
1. An apparatus for inspecting ventilation of filter cigarettes, comprising: a fluid machine for producing pressure difference between both ends of a test-gas transmitting path including at least one end portion of a filter cigarette to be inspected; a measuring instrument provided on the transmitting path, for measuring a quantity of the test gas; a port provided in the transmitting path, for receiving the one end portion of the filter cigarette from one opening end of said port; and a plate-like packing covering another opening end of said port, for being pressed with the end face of the filter cigarette, the packing including a hole positioned in a center thereof, a flat inner circular area surrounding the hole, and a flat outer circular area surrounding the inner flat circular area, the flat outer circular area being elastically deformable more easily than the flat inner circular area, wherein, when a filter cigarette is inspected, the flat inner circular area of the plate-like packing is brought into surface contact with the end face of the filter cigarette, and the flat outer circular area of the plate-like packing is brought into tight contact with the outer circumferential edge of the end face of the filter cigarette.
