Abstract

Example embodiments relate to a cartridge configured to house a pre-vapor formulation for an e-vaping device, the cartridge including an inner portion and an outer portion configured to store the pre-vapor formulation. The outer portion includes a plurality of fibers configured to be mobile and/or configured to be substantially free of entanglement with one another. The fibers are configured to be substantially free of entanglement with one another based on the lengths of the plurality of fibers. For example, the lengths of the plurality of fibers may be in a range of about 3 mm to about 7 mm. The lengths may also be about 5 mm.

First claim

What is claimed is:

1. A storage medium, the storage medium including:
a gauze configured to absorb a pre-vapor formulation, and
a plurality of fibers dispersed in the gauze and configured to be mobile with respect to one another, the plurality of fibers being insoluble in the pre-vapor formulation,
the gauze and plurality of fibers being different material, respective lengths of the plurality of fibers are in a range of about 3 mm to about 7 mm.

2. The storage medium of claim 1 , wherein the plurality of fibers are configured to be mobile with respect to one another based on the respective lengths of the plurality of fibers.

3. The storage medium of claim 1 , wherein the respective lengths of the plurality of fibers are about 5 mm.

4. The storage medium of claim 1 , wherein about 30% of the plurality of fibers have a length of about 3 mm, about 50% of the plurality of fibers have a length of about 5 mm, and about 20% of the plurality of fibers have a length of about 7 mm.

5. The storage medium of claim 1 , wherein about 20% of the plurality of fibers have a length of about 3 mm, about 75% of the plurality of fibers have a length of about 5 mm, and about 5% of the plurality of fibers have a length of about 7 mm.

6. The storage medium of claim 1 , wherein about 30% of the plurality of fibers have a length of about 3 mm, about 60% of the plurality of fibers have a length of about 5 mm, and about 10% of the plurality of fibers have a length of about 7 mm.

7. The storage medium of claim 1 , wherein a surface area of each of the plurality of fibers is in a range of about 13 in 2 to about 17 in 2 .

8. The storage medium of claim 7 , wherein the surface area of each of the plurality of fibers is about 15 in 2 .

9. The storage medium of claim 1 , wherein the gauze and the plurality of fibers are configured to cooperatively wring the pre-vapor formulation from the storage medium, based on the plurality of fibers being free to move independently of each other.

10. A storage medium, the storage medium including:
a gauze configured to absorb a pre-vapor formulation, and
a plurality of fibers in the gauze and configured to be mobile with respect to one another, the gauze and plurality of fibers being different materials, the plurality of fibers being insoluble in the pre-vapor formulation, wherein a diameter of one or more of the plurality of fibers is in a range of about 20 μm to about 28 μm.

11. The storage medium of claim 10 , wherein the diameter of one or more of the plurality of fibers is about 24 μm.

12. The storage medium of claim 10 , wherein about 30% of the plurality of fibers have a length of about 3 mm, about 50% of the plurality of fibers have a length of about 5 mm, and about 20% of the plurality of fibers have a length of about 7 mm.

13. The storage medium of claim 10 , wherein about 20% of the plurality of fibers have a length of about 3 mm, about 75% of the plurality of fibers have a length of about 5 mm, and about 5% of the plurality of fibers have a length of about 7 mm.

14. The storage medium of claim 10 , wherein about 30% of the plurality of fibers have a length of about 3 mm, about 60% of the plurality of fibers have a length of about 5 mm, and about 10% of the plurality of fibers have a length of about 7 mm.

15. The storage medium of claim 10 , wherein a surface area of each of the plurality of fibers is in a range of about 13 in 2 to about 17 in 2 .

16. The storage medium of claim 15 , wherein the surface area of each of the plurality of fibers is about 15 in 2 .

17. The storage medium of claim 10 , wherein the gauze and the plurality of fibers are configured to cooperatively wring the pre-vapor formulation from the storage medium, based on the plurality of fibers being free to move independently of each other.

18. A storage medium, the storage medium including:
a gauze configured to store a pre-vapor formulation, and
a plurality of fibers in the gauze and configured to be mobile with respect to one another, the gauze and plurality of fibers being different materials, the plurality of fibers being a matrix of polymer fibers configured to compress the gauze based on a low moisture state of the storage medium.

19. The storage medium of claim 18 , wherein a surface area of each of the plurality of fibers is in a range of about 13 in 2 to about 17 in 2 .

20. The storage medium of claim 19 , wherein the surface area of each of the plurality of fibers is about 15 in 2 .
