Design and application of a multi-chamber cartridge including a hydrogel formulation

An e-vaping device, comprising:

• a cartridge including:
• an outer container extending in a longitudinal direction;
• a conduit within the outer container;
• a storage portion between the outer container and the conduit, the storage portion being configured to store pre-vapor formulation ingredients, and including a plurality of chambers, the plurality of chambers configured to each store pre-vapor formulation ingredients including at least one of nicotine, flavorants, aroma, acids, propylene glycol, glycerol and a combination thereof;
• a wick in fluid communication with at least one of the plurality of chambers and the conduit and being configured to deliver one or more ingredients in each of the plurality of chambers to the conduit;
• and
• a heater operatively coupled to the wick;
• and
• a power supply source coupled to the cartridge, the power supply source being configured to power the heater to heat the pre-vapor formulation ingredients via the one or more of the plurality of wicks.

A method of operating an e-vaping device, the e-vaping device including an outer shell and an inner conduit, a storage portion between the outer shell and the inner conduit being configured to store ingredients of a pre-vapor formulation and including a plurality of chambers, and a mouth-end insert, the method comprising:

• storing one or more ingredients of the pre-vapor formulation in one or more of the plurality of chambers;
• connecting one or more of the plurality of chambers with the inner conduit via a respective wick configured to deliver the one or more ingredients present in the one or more of the plurality of chambers to the inner conduit;
• upon operation of the e-vaping device, vaporizing each of the ingredients delivered, from each of the one or more of the plurality of chambers, in the inner conduit to generate vaporized ingredients;
• and
• expressing a combination of the vaporized ingredients through the mouth-end insert.
