  • Publication number: 20220240596
    Abstract: Exposure of a leftover material at a cartridge that forms a vapor product is prevented. There is provided a cartridge that is assembled in a part of a vapor product that includes a heating element for heating an aerosol source. The cartridge includes a first component and a second component, at least one of which being formed of resin, and a connection section whose one end is connected to the first component and whose another end is joined or welded to the second component. The second component includes a recessed section. The other end of the connection section is joined or welded to the recessed section.

  • Patent number: 9568440
    Abstract: An approximate circle approximated to the profile of a filter end face in an inspection image obtained by photographing the filter end face of a filter cigarette is obtained, and the center position of the approximate circle is found. An area indicating a string-like flavor containing element embedded in the filter is detected in the inspection image, and the position of gravity center of the area is found. Distance between the gravity center position indicating the flavor containing element and the center position of the approximate circle is determined, and thus, the quality of the flavor containing element embedded in the filter is inspected.

  • Patent number: 8605984
    Abstract: A cigarette inspection device for inspecting a filter quality through an inspection image of filter end faces in a bundle of cigarettes for accurately detecting, for example, only contaminations. A pattern image is used for detecting a cigarette location on the basis of a preset location of each cigarette in the cigarette bundle and a search area on the inspection image is set. The pattern image is shifted within the search area, thereby obtaining a position at which the pattern image coincides with an image of the filter end face. An image of a filter end face of the cigarette is cut out from the inspection image according to the detected position, and quality (contamination) is inspected. Inspection results obtained with respect to the cigarettes are aggregated, and a judgment is made on the quality (presence or absence of a contamination) of the filter end face.
