Abstract

A cartridge may include a housing, a liquid supply reservoir in the housing and configured to store a pre-vapor formulation, a vaporizer, and a porous plug. The vaporizer may be in liquid communication with the liquid supply reservoir. The vaporizer may be configured to generate a vapor from heating a portion of the pre-vapor formulation. The porous plug may be connected to the housing and separated from the liquid supply reservoir. The porous plug may be permeable to the vapor. The porous plug may enclose a flavoring additive contacting a storage material. The flavoring additive may be configured to at least partially elute from the storage material or at least partially volatilize from the storage material if the vapor flows through the porous plug. An e-vaping device may include the cartridge.

First claim

What is claimed is:

1. A cartridge, comprising:
a housing including a first end opposite a second end;
a liquid supply reservoir in the housing and configured to store a pre-vapor formulation;
a vaporizer in the housing and in liquid communication with the liquid supply reservoir, the vaporizer being configured to generate a vapor from heating a portion of the pre-vapor formulation;
a tip structure connected to the first end of the housing, the tip structure outside the housing;
a mouth-end insert in the housing at the first end, the mouth-end insert between the vaporizer and the tip structure; and
a porous plug in the tip structure, wherein
the porous plug is permeable to the vapor,
the porous plug encloses a flavoring additive contacting a storage material, and
the flavoring additive is configured to at least partially elute from the storage material or at least partially volatilize from the storage material in response to the vapor flowing through the porous plug.

2. The cartridge of claim 1 , wherein
the flavoring additive includes one of menthol, limonene, benzaldehyde, ethyl vanoline, and
the storage material includes one of a botanic material and a non-botanic material.

3. The cartridge of claim 1 , wherein the flavoring additive includes menthol.

4. The cartridge of claim 1 , wherein
the storage material includes one of a botanic material and a non-botanic material, and
the botanic material includes one of menthol crystal, mint leaves, tea leaves, coffee powder, dry flowers, lemon grass, orange peels, star anise, and clove, and the non-botanic material includes one of paper, cellulose, zerolite, cellulose acetate with acid, cellulose acetate without acid, and a polymer.

5. The cartridge of claim 1 , wherein
the porous plug is a bag containing the flavoring additive and the storage material, and
a material of the bag includes one of porous aluminum foil, perforated aluminum foil, nylon, filter paper, silk, plastic, and cellulose acetate.

6. The cartridge of claim 1 , further comprising:
the pre-vapor formulation in the liquid supply reservoir, wherein
the pre-vapor formulation includes nicotine and at least one of glycerin (Gly) and propylene glycol, and
the flavoring additive is configured to adsorb to the storage material or absorb in the storage material.

7. The cartridge of claim 1 , wherein
a volume ratio of the liquid supply reservoir to the porous plug is in a range of about 10:90 (liquid supply volume: porous plug volume) to about 90:10 (liquid supply volume: porous plug volume).

8. The cartridge of claim 1 , wherein
a weight ratio of the flavoring additive to the storage material ranges from about 1:99 (flavoring additive: storage material) to 80:20 (flavoring additive: storage material).

9. The cartridge of claim 1 , further comprising:
an inner gasket in the housing.

10. A method of making an e-vaping device, comprising:
connecting the cartridge of claim 1 to a battery section such that the battery section and cartridge are removably coupled to each other, wherein
the battery section includes a power supply, and
the power supply is configured to provide power to the vaporizer for the vaporizer generating the vapor from the pre-vapor formulation.

11. A cartridge, comprising:
a housing including first and second ends that are opposite each other and in fluid communication with each other through a channel;
a liquid supply reservoir in the housing and configured to store pre-vapor formulation;
a vaporizer in the housing and in liquid communication with the liquid supply reservoir, the vaporizer being configured to generate a vapor from the pre-vapor formulation;
a tip structure connected to the first end of the housing, the tip structure outside the housing;
a mouth-end insert in the housing at the first end, the mouth-end insert between the vaporizer and the tip structure; and
a porous plug in the tip structure, wherein
the porous plug encloses a flavoring additive and at least one of a botanic material and a non-botanic material, and
the porous plug is permeable to the vapor.

12. The cartridge of claim 11 , wherein
the botanic material includes one of menthol crystal, mint leaves, tea leaves, coffee powder, dry flowers, lemon grass, orange peels, star anise, and clove, and
the non-botanic material includes one of paper, cellulose, zerolite, cellulose acetate with acid, cellulose acetate without acid, and a polymer.

13. The cartridge of claim 11 , wherein
the porous plug is a bag containing the flavoring additive and a storage material,
a material of the porous plug includes one of perforated aluminum foil, porous aluminum foil, nylon, filter paper, silk, plastic, and cellulose acetate, and
the flavoring additive is adsorbed onto the storage material or absorbed in the storage material.

14. A method of making a cartridge, the method comprising:
forming a liquid supply reservoir and a vaporizer in a housing,
the liquid supply reservoir being configured to store a pre-vapor formulation,
the vaporizer being in liquid communication with the liquid supply reservoir,
the vaporizer being configured to generate a vapor from heating a portion of the pre-vapor formulation;
arranging a mouth-end insert in the housing;
arranging a tip structure connected to the housing, the tip structure outside the housing, such that the mouth-end insert in the housing is between the vaporizer and the tip structure; and

arranging a porous plug in the tip structure, wherein
the porous plug is permeable to the vapor,
the porous plug encloss a flavoring additive contacting a storage material, and
the flavoring additive is configured to at least partially elute from the storage material or at least partially volatilize from the storage material in response to the vapor flowing through the porous plug.

15. The method of claim 14 , wherein
the storage material includes one of a botanic material and a non-botanic material,
the botanic material includes one of menthol crystal, mint leaves, tea leaves, coffee powder, and dry flowers, and
the non-botanic material includes one of paper, cellulose, zerolite, and a polymer.
