Articles formed of pulp base materials with modulated scent release
Described are articles formed of a pulp base material comprising fibers, wherein pores are formed between the fibers. A volatile composition with at least one top note component and at least one base note component at least partially fills the pores of the pulp base material. A release rate of the at least one top note component is modulated by the pulp base material, and a release rate of the at least one base note component is enhanced by the pulp base material.
1. An article comprising
a pulp base material comprising:
fibers, wherein pores are formed between the fibers;
at least one low porosity zone having a first porosity; and
at least one high porosity zone having a second porosity;

a volatile composition comprising at least one top note component having a first volatility and at least one base note component having a second volatility, wherein the first volatility is higher than the second volatility;
wherein the volatile composition at least partially fills the pores of the pulp base material;
wherein a release rate of the at least one top note component is modulated by the pulp base material; and
wherein a release rate of the at least one base note component is enhanced by the pulp base material.
2. The article of claim 1 , wherein a modulating coating is applied to the pulp base material.
3. The article of claim 1 , wherein
the volatile composition is mixed with a dye before at least partially filling the pores of the pulp base material such that the at least two zones with different porosities each have a different visual appearance;
wherein the at least one low porosity zone has a darker visual appearance than the at least one high porosity zone.
4. The article of claim 1 , further comprising a second material disposed within the pulp base material.
5. The article of claim 4 , wherein the second material comprises a biological plant-derived material.
6. The article of claim 4 , wherein the second material comprises a scented rod of spiral wound paper.
7. The article of claim 4 , wherein the second material is disposed within at least one opening of the pulp base material.
8. The article of claim 4 , wherein the second material has a different porosity than the pulp base material at least prior to disposing the second material within the pulp base material.
9. The article of claim 4 , wherein the second material comprises second fibers, wherein the second fibers are from a different source compared to the fibers of the pulp base material.
10. An article comprising
a pulp base material comprising:
fibers, wherein pores are formed between the fibers;
at least one low density zone having a first density; and
at least one high density zone having a second density;
wherein the first density is lower than the second density;
a volatile composition comprising at least one top note component having a first volatility and at least one base note component having a second volatility, wherein the first volatility is higher than the second volatility;
wherein the volatile composition at least partially fills the pores of the pulp base material;
wherein a release rate of the at least one top note component is modulated by the pulp base material; and
wherein a release rate of the at least one base note component is enhanced by the pulp base material.
11. The article of claim 10 , wherein a modulating coating is applied to the pulp base material.
12. The article of claim 10 , wherein
the volatile composition is mixed with a dye before at least partially filling the pores of the pulp base material such that the at least two zones with different densities each have a different visual appearance;
wherein the at least one high density zone has a darker visual appearance than the at least one low density zone.
13. An article comprising
a pulp base material comprising fibers, wherein pores are formed between the fibers;
a second material disposed within the pulp base material;
the combined materials comprising:
at least one low density zone having a first density; and
at least one high density zone having a second density;
wherein the first density is lower than the second density;
a volatile composition comprising at least one top note component having a first volatility and at least one base note component having a second volatility, wherein the first volatility is higher than the second volatility;
wherein the volatile composition at least partially fills the pores of the combined materials;
wherein a release rate of the at least one top note component is modulated by the combined materials; and
wherein a release rate of the at least one base note component is enhanced by the combined materials.
14. The article of claim 13 , wherein the second material comprises a biological plant-derived material.
15. The article of claim 13 , wherein the second material comprises a scented rod of spiral wound paper.
16. The article of claim 13 , wherein the second material is disposed within at least one opening of the pulp base material.
17. The article of claim 13 , wherein the second material has a different density than the pulp base material at least prior to disposing the second material within the pulp base material.
18. The article of claim 13 , wherein the second material comprises second fibers, wherein the second fibers are from a different source compared to the fibers of the pulp base material.
19. The article of claim 13 , wherein a modulating coating is applied to the combined materials.
20. The article of claim 13 , wherein
the volatile composition is mixed with a dye before at least partially filling the pores of the combined materials such that the at least two zones with different densities each have a different visual appearance; and
the at least one high density zone has a darker visual appearance than the at least one low density zone.
