Reconstituted plant with plant extract for devices that heat tobacco without burning it
The invention relates to a reconstituted plant leaf comprising plant fibres and a plant extract other than the tobacco plant suitable for devices that heat tobacco without burning it.
1. A reconstituted plant leaf comprising:
a fibrous substrate, wherein the fibrous substrate is a reconstituted base-web comprising refined plant fibers from a plant, wherein the reconstituted base-web is obtained by a papermaking process;
an aerosol-generating agent, and
a plant extract from the same plant species as the refined plant fibers characterized in that the plant fibres represent from 30% to 92% by weight of dry matter of the reconstituted plant leaf,
the plant extract represents from 12% to 46% by weight of dry matter of the reconstituted plant leaf, wherein all components of the plant extract are derived from a plant, the plant fibres and plant extract are not from a tobacco plant and the aerosol-generating agent represents from 10% to 50% by weight of the dry matter of the leaf.
2. The reconstituted plant leaf according to claim 1 , in which the aerosol-generating agent is sorbitol, glycerol, propylene glycol, triethylene glycol, lactic acid, glyceryl diacetate, glyceryl triacetate, triethyl citrate, isopropyl myristate or a mixture thereof.
3. The reconstituted plant leaf according to claim 1 , in which the fibrous substrate further comprises a tobacco extract, wherein the ratio of the content by weight of dry matter of the plant extract contained in the reconstituted plant leaf to the content by weight of dry matter of the tobacco extract contained in the reconstituted plant leaf is from 95:5 to 5:95.
4. The reconstituted plant leaf according to claim 1 , in which the plant fibres represent from 40% to 75% by weight of dry matter of the reconstituted plant leaf.
5. The reconstituted plant leaf according to claim 1 , in which the plant fibres and the plant extract are selected from spore-producing plants, seed-producing plants or a mixture thereof.
6. The reconstituted plant leaf according to claim 1 , having a basis weight from 20 g/m 2 to 150 g/m 2.
7. The reconstituted plant leaf according to claim 1 , further comprising particles selected from plant particles, tobacco particles, or a mixture thereof, wherein the particles represent from 5% to 65% by weight of dry matter of the reconstituted plant leaf.
8. The reconstituted plant leaf according to claim 1 , in which the plant fibres represent from 50% to 60% by weight of dry matter of the reconstituted plant leaf.
9. The reconstituted plant leaf according to claim 1 , in which the plant fibres, the plant extract, or both, comprise components from a rooibos plant.
10. The reconstituted plant leaf according to claim 1 , wherein the fibrous substrate does not comprise whole plant leaves.
11. A mixture of reconstituted leaves/tobacco comprising tobacco and the reconstituted plant leaf of claim 1 .
12. A papermaking process for making the reconstituted plant leaf of claim 1 comprising the following steps:
passing the plant fibres through a papermaking machine to constitute a plant base web; and
incorporating the aerosol-generating agent and optionally the extract in the plant base web.
13. A blend of reconstituted leaves comprising the reconstituted plant leaf of claim 1 combined with a mixed reconstituted leaf comprising:
a fibrous substrate comprising tobacco fibres,
an aerosol-generating agent, and
plant extract,
characterized in that the plant is not a tobacco plant and the aerosol-generating agent represents from 8 to 50% by weight of the dry matter of the leaf.
