Cartridges for vaporizer devices

Abstract

Cartridges for vaporizer devices are provided. In one exemplary embodiment, the cartridge can include a primary reservoir, a secondary reservoir in fluid communication with the primary reservoir, and a vaporization chamber in communication with the secondary reservoir in which the vaporization chamber includes a first wicking element. The primary reservoir is configured to store a majority fraction of vaporizable material when in a first pressure state and configured to expel the vaporizable material in response to an increase in headspace when in a second pressure state. The secondary reservoir is formed of absorbent material configured to receive a first volume of the vaporizable material from the primary reservoir in the first pressure state and to receive a second volume of the vaporizable material from the primary reservoir in the second pressure state in which the second volume is greater than the first volume. Vaporizer devices are also provided.

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 755,895, filed November 5, 2018, entitled "Cartridge for Evaporator Apparatus," the disclosure of which is incorporated by reference in its entirety to the extent permitted Incorporated into this article. technical field [0003] The subject matter described herein relates to an evaporator apparatus including an evaporator cartridge. Background technique [0004] Evaporator devices, also known as vaporizers, electronic vaporizer devices, or e-evaporator devices, can be used to deliver an aerosol containing one or more active ingredients (e.g., a gaseous and / or condensed phase material, suspended In a stationary or moving mass of air (or some other gaseous carrier), the delivery is achieved by inhalation of the aerosol by the user of the vaporization device. Electronic nicotine delivery systems (ENDS), for example, include a class of batter...

Problems solved by technology

[0011] Vaporizable material leaks are problematic because such leaks often interfere with the function and cleanliness of the vaporizer unit (e.g. leaked vaporizable material clogs electrical ports or creates a mess that requires cleaning)

Additionally, leakage of evaporable material from a cartridge can negatively impact the user experience due to the potential to contaminate or damage other items or fabrics in the vicinity of the leaking cartridge

Leakage into the cartridge or parts of the vaporizer unit may also cause the liquid vaporizable material to bypass the vaporization chamber, causing the user to experience an unpleasant sensation from inhaling the vaporizable material in liquid form
