  • Patent number: 12225936
    Abstract: A disposable capsule, containing herbal product such as cannabis, can be used with a vaporizer for vaporizing the volatile constituents. The limited battery capacity of portable vaporizers necessitates efficient energy use in order to generate vapor from the herbal product. This is achieved through various features of the invention. Aided by airtightness of the vaporizer capsule connection, the airflow through the capsule can be guided in a controlled fashion.
