Abstract: A mouthpiece device is provided for interconnection with a personal vaporizer device. The mouthpiece is connectable to a cartridge and comprises connection members to securely interconnect the mouthpiece and the cartridge. In some embodiments, at least one connection member is provided that is detachable from a remainder of the mouthpiece to prevent tampering with a mouthpiece or a cartridge.

Abstract: A vaporizer device including a body having a mouthpiece, a power source, a regulator coupled to the power source, a cavity configured to receive a vaporizer cartridge, and one or more airflow pathways configured to interconnect with an airflow coupler associated with a vaporizer cartridge. The vaporizer device may include a sensor configured to detect a pressure change in the one or more airflow pathways between the vaporizer cartridge and the mouthpiece. The vaporizer device may include a controller configured to control the regulator, and a data interface coupled to the processor, the data interface being configured to contact a receiving portion of a vaporizer cartridge when the vaporizer cartridge is inserted into the cavity.

Abstract: A dispensing device for storing and dispensing oils and other viscous liquids is provided. The device comprises an elongate body member and a dispensing tip. The dispensing tip comprises a valve member that is biased toward a closed position to prevent unwanted egress of device contents. In order to dispense device contents, a force is applied to the contents within the device, and that force is transmitted to the valve member to urge the valve member toward a temporary open position and allow contents to be dispensed.
