Abstract
Vaporizer device cartridges are provided. In some implementations, a cartridge comprises a storage compartment having first and second opposing ends, a sealing material sealing the second end, and a wick positioned proximate to the first end. The storage compartment is configured to hold a liquid vaporizable material. The sealing material is configured for insertion of a needle through the sealing material for dispensing the liquid vaporizable material into the storage compartment. The wick comprises opposing ends in communication with the storage compartment and is configured to allow a volume of air to exit the storage compartment through the wick when the storage compartment is being filled with the liquid vaporizable material.
