| مستخلص: | Substrates for use with an aerosol delivery device to vaporize and deliver an aerosol to a user include a base material, an aerosol former and an aerosol agent. In a method for forming the substrates, a mixture of substrate materials is extruded and then spheronized to produce pellet substrates that are generally spherical, substantially spherical or rounded, or in the form of relatively short rods having rounded ends. In another method for forming the substrates, a base material is coated with a first coating and optionally the base material having the first coating thereon is subsequently coated with a second coating so as to produce pellet substrates having a relatively smooth, dry exterior surface. In this manner, the substrates are formable relative to one another and can be easily and readily loaded into and removed from the aerosol delivery device. |

| Claim: | 1. Substrates for use with an aerosol delivery device to vaporize and deliver an aerosol, comprising: a mixture in the form of an extrudable paste comprising an uncoated base material and an aerosol former; wherein the uncoated base material comprises an organic fiber that is ground into a powder before being mixed with the aerosol former; and wherein the extrudable paste is extruded to form rod-like substrates having a length that is about 2-4 times a diameter of the rod-like substrates, the diameter is from about 0.5 mm to about 2 mm, and the length is from about 1 mm to about 4 mm. |
| Claim: | 2. Substrates according to claim 1 , wherein the substrates formed by extruding the extrudable paste are formed into short rods having rounded ends. |
| Claim: | 3. Substrates according to claim 1 , wherein the substrates are spheronized after the extrudable paste is extruded. |
| Claim: | 4. Substrates according to claim 1 , wherein the organic fiber is selected from the group consisting of a food fiber and a plant fiber. |
| Claim: | 5. Substrates according to claim 4 , wherein the organic fiber of the base material is selected from the group consisting of a hemp biomass and a peppermint leaf. |
| Claim: | 6. Substrates according to claim 1 , wherein the aerosol former is selected from the group consisting of glycerin, vegetable glycerin, and mixtures thereof. |
| Claim: | 7. Substrates according to claim 1 , wherein the mixture further comprises a hydrocolloid. |
| Claim: | 8. Substrates according to claim 7 , wherein the hydrocolloid comprises a hydrated water-soluble gum. |
| Claim: | 9. Substrates according to claim 1 , wherein the mixture further comprises an aerosol agent in the form of a dissolved aspirin. |
| Claim: | 10. Substrates according to claim 1 , wherein the mixture further comprises an aerosol agent in the form of a tetrahydrocannabinol (THC) oil, a cannabidiol (CBD) oil, or mixtures thereof. |
| Claim: | 11. Process for producing substrates according claim 1 for use with an aerosol delivery device to vaporize and deliver an aerosol, comprising: grinding an uncoated base material comprising an organic fiber into a powder; mixing the powder of the base material with an aerosol former into a mixture in the form of an extrudable paste; extruding the paste of the mixture to form rod-like substrates. |
| Claim: | 12. Process according to claim 11 further comprising forming the extruded substrates into short rods having rounded ends. |
| Claim: | 13. Process according to claim 11 further comprising spheronizing the extruded substrates to form spherical, substantially spherical or rounded substrates. |
| Claim: | 14. Process according to claim 11 , wherein the organic fiber is selected from the group consisting of a food fiber and a plant fiber. |
| Claim: | 15. Process according to claim 11 , wherein the base material is selected from the group consisting of hemp biomass and peppermint leaf. |
| Claim: | 16. Process according to claim 11 , wherein the aerosol former is selected from the group consisting of glycerin, vegetable glycerin and mixtures thereof. |
| Claim: | 17. Process according to claim 11 , wherein the mixture further comprises a hydrocolloid. |
| Claim: | 18. Process according to claim 17 , wherein the hydrocolloid comprises a hydrated water-soluble gum. |
| Claim: | 19. Process according to claim 11 , wherein the mixture further comprises an aerosol agent selected from the group consisting of a dissolved aspirin, a THC oil, a CBD oil, and mixtures thereof. |
| Claim: | 20. Substrates for delivering an aerosol, comprising: a base material comprising an organic fiber selected from the group consisting of a hemp biomass and a peppermint leaf that is ground into a powder; an aerosol former selected from the group consisting of glycerin, vegetable glycerin, and mixtures thereof; and an aerosol agent selected from the group consisting of a dissolved aspirin, a tetrahydrocannabinol (THC) oil, a cannabidiol (CBD) oil, or mixtures thereof; wherein the base material, the aerosol former and the aerosol agent are mixed together to form an extrudable paste; wherein the extrudable paste is extruded into SA-eft-rods having rounded ends to form the substrates; and wherein the rods have a length that is about 2-4 times a diameter of the rods, the diameter is from about 0.5 mm to about 2 mm, and the length is from about 1 mm to about 4 mm. |
