Cartridge for an aerosol-generating system
There is provided a cartridge for an aerosol-generating system, the cartridge including a liquid storage container containing: a first liquid composition and a second composition; a plurality of capsules, each capsule encapsulating the second composition to separate the second composition from the first liquid composition, each capsule including a frangible shell encapsulating the second composition; a capsule retainer; and an outlet in the liquid storage container configured to deliver liquid from the liquid storage container, the capsule retainer substantially preventing any frangible shells, or parts thereof, from exiting the cartridge through the outlet. An aerosol-generating device configured to receive the cartridge to form an aerosol-generating system is also provided.
1. A cartridge for an aerosol-generating system, the cartridge comprising:
a liquid storage container containing a first liquid composition and a second composition;
a plurality of capsules, each capsule encapsulating the second composition to separate the second composition from the first liquid composition, wherein each capsule comprises a frangible shell encapsulating the second composition;
a capsule retainer; and
an outlet in the liquid storage container configured to deliver liquid from the liquid storage container, wherein the capsule retainer substantially prevents any frangible shells, or parts thereof, from exiting the cartridge through the outlet.
2. The cartridge according to claim 1 , wherein the second composition is a liquid.
3. The cartridge according to claim 1 , wherein the second composition is a liquid, and each capsule further comprises a porous element having the second liquid composition sorbed thereon.
4. The cartridge according to claim 1 , further comprising at least two sets of capsules, the first set comprising the plurality of capsules encapsulating the second composition, and the second set comprising another plurality of capsules comprising a shell encapsulating a third composition.
5. The cartridge according to claim 1 , further comprising a solid body freely movable within the liquid storage container.
6. The cartridge according to claim 1 , wherein the liquid storage container comprises a flexible wall and the capsule retainer is an adhesive configured to adhere the capsules to at least one wall of the liquid storage container.
7. The cartridge according to claim 1 , wherein the capsule retainer comprises a filter element.
8. The cartridge according to claim 7 , wherein the filter element is movable between a first position adjacent the outlet to a second position remote from the first position.
9. The cartridge according to claim 8 , further comprising a liquid transport element coupled to the filter element, the liquid transport element extending through the outlet.
10. The cartridge according to claim 1 , wherein the first liquid composition comprises an aerosol-forming substrate.
11. An aerosol-generating system, comprising:
a cartridge comprising:
a liquid storage container containing a first liquid composition and a second composition,
a plurality of capsules, each capsule encapsulating the second composition to separate the second composition from the first liquid composition, wherein each capsule comprises a frangible shell encapsulating the second composition,
a capsule retainer, and
an outlet in the liquid storage container configured to deliver liquid from the liquid storage container, wherein the capsule retainer substantially prevents any frangible shells, or parts thereof, from exiting the cartridge through the outlet; and
a device configured to receive the cartridge, the device comprising:
a housing having a cavity configured to receive the cartridge,
a liquid transport element comprising a first portion insertable into the outlet of the cartridge, and a second portion,
a heating element adjacent the second portion of the liquid transport element, and
a power supply configured to supply power to the heating element.
12. The aerosol-generating system according to claim 11 , further comprising an actuator configured to engage the cartridge with the liquid transport element when the cartridge is received in the cavity.
13. The aerosol-generating system according to claim 11 , further comprising a capsule rupturing device, the device being at least one of: an ultrasonic generator, an ultraviolet light, and a crusher.
